Services like ACPI namespace are not available and there are non-trivial problems to moving them to early boot. However, there's no reason we can't change to a different machvec later in boot when the services we need are available. By adding a entry point for later initialization of the swiotlb, we can add an error path for the hpzx1 machevec initialization and fall back to the DIG machine vector if IOMMU hardware isn't found in the system. Since ia64 uses 4GB for zone DMA (no ISA support), it's trivial to allocate a contiguous range from the slab for bounce buffer usage.

Without PNP, it probes legacy I/O ports for the keyboard controller, which causes an MCA on HP boxes. Also, I'm about to remove 8250_acpi.c, so we'll need PNP to detect non-PCI serial ports. Until 8250_acpi.c is removed, some systems will see serial ports reported twice (once from 8250_acpi.c and again from 8250_pnp.c). This is harmless. PNPACPI is still marked EXPERIMENTAL, but I'm not aware of any outstanding issues on ia64. IDE_GENERIC turned off (except for SGI simulator, all ia64 IDE is PCI) ide-generic probes compiled-in legacy I/O ports for IDE devices, which again causes an MCA. It would be nicer to just get rid of all the legacy junk from include/asm-ia64/ide.h, but that is a bit riskier because it could break ide-cs and the HDIO_REGISTER_HWIF ioctl (http://www.ussg.iu.edu/hypermail/linux/kernel/0508.2/0049.html).

This patch attempts to clean them up. Some of the various SN MAX_xxx #defines were also unclear & misused. The primary changes are: - use MAX_NUMNODES. This is the generic linux #define for the number of nodes that are known to the generic kernel. Arrays & loops for constructs that are 1:1 with linux-defined nodes should use the linux #define - not an SN equivalent. - use MAX_COMPACT_NODES for MAX_NUMNODES + NUM_TIOS. This is the number of nodes in the SSI system. Compact nodes are a hack to get around the IA64 architectural limit of 256 nodes. Large SGI systems have more than 256 nodes. When we upgrade to ACPI3.0, I _hope_ that all nodes will be real nodes that are known to the generic kernel. That will allow us to delete the notion of "compact nodes". - add MAX_NUMALINK_NODES for the total number of nodes that are in the numalink domain - all partitions. - simplified (understandable) scan_for_ionodes() - small amount of cleanup related to cnodes Signed-off-by: Jack Steiner Signed-off-by: Tony Luck diff --git a/arch/ia64/sn/kernel/io_init.c b/arch/ia64/sn/kernel/io_init.c index 906622d..b4f5053 100644 --- a/arch/ia64/sn/kernel/io_init.c +++ b/arch/ia64/sn/kernel/io_init.c @@ -22,8 +22,6 @@ #include "xtalk/hubdev.h" #include "xtalk/xwidgetdev.h" -nasid_t master_nasid = INVALID_NASID; /* Partition Master */ - static struct list_head sn_sysdata_list; /* sysdata list struct */ @@ -165,7 +163,7 @@ static void sn_fixup_ionodes(void) * Get SGI Specific HUB chipset information. * Inform Prom that this kernel can support domain bus numbering. */ - for (i = 0; i < numionodes; i++) { + for (i = 0; i < num_cnodes; i++) { hubdev = (struct hubdev_info *)(NODEPDA(i)->pdinfo); nasid = cnodeid_to_nasid(i); hubdev->max_segment_number = 0xffffffff; diff --git a/arch/ia64/sn/kernel/setup.c b/arch/ia64/sn/kernel/setup.c index 6f8c588..0fb579e 100644 --- a/arch/ia64/sn/kernel/setup.c +++ b/arch/ia64/sn/kernel/setup.c @@ -59,8 +59,6 @@ DEFINE_PER_CPU(struct pda_s, pda_percpu); #define MAX_PHYS_MEMORY (1UL << IA64_MAX_PHYS_BITS) /* Max physical address supported */ -lboard_t *root_lboard[MAX_COMPACT_NODES]; - extern void bte_init_node(nodepda_t *, cnodeid_t); extern void sn_timer_init(void); @@ -97,15 +95,15 @@ u8 sn_region_size; EXPORT_SYMBOL(sn_region_size); int sn_prom_type; /* 0=hardware, 1=medusa/realprom, 2=medusa/fakeprom */ -short physical_node_map[MAX_PHYSNODE_ID]; +short physical_node_map[MAX_NUMALINK_NODES]; static unsigned long sn_prom_features[MAX_PROM_FEATURE_SETS]; EXPORT_SYMBOL(physical_node_map); -int numionodes; +int num_cnodes; static void sn_init_pdas(char **); -static void scan_for_ionodes(void); +static void build_cnode_tables(void); static nodepda_t *nodepdaindr[MAX_COMPACT_NODES]; @@ -140,19 +138,6 @@ char drive_info[4 * 16]; #endif /* - * Get nasid of current cpu early in boot before nodepda is initialized - */ -static int -boot_get_nasid(void) -{ - int nasid; - - if (ia64_sn_get_sapic_info(get_sapicid(), &nasid, NULL, NULL)) - BUG(); - return nasid; -} - -/* * This routine can only be used during init, since * smp_boot_data is an init data structure. * We have to use smp_boot_data.cpu_phys_id to find @@ -223,7 +208,6 @@ void __init early_sn_setup(void) } extern int platform_intr_list[]; -extern nasid_t master_nasid; static int __initdata shub_1_1_found = 0; /* @@ -269,7 +253,6 @@ static void __init sn_check_for_wars(void) void __init sn_setup(char **cmdline_p) { long status, ticks_per_sec, drift; - int pxm; u32 version = sn_sal_rev(); extern void sn_cpu_init(void); @@ -300,11 +283,10 @@ void __init sn_setup(char **cmdline_p) MAX_DMA_ADDRESS = PAGE_OFFSET + MAX_PHYS_MEMORY; - memset(physical_node_map, -1, sizeof(physical_node_map)); - for (pxm = 0; pxm < MAX_PXM_DOMAINS; pxm++) - if (pxm_to_nid_map[pxm] != -1) - physical_node_map[pxm_to_nasid(pxm)] = - pxm_to_nid_map[pxm]; + /* + * Build the tables for managing cnodes. + */ + build_cnode_tables(); /* * Old PROMs do not provide an ACPI FADT.

I don't think that NODELAY option hurts performance. However, open-iscsi does not use MSG_MORE properly with sendpage, so NODELAY option hurts the open-iscsi performance. I've attached a patch to fix NODELAY and MSG_MORE problems and the write performance results with disktest. I use Opteron boxes connected directly, Chelsio NICs, 1500-byte MTU, 64 KB I/O size, and the iSCSI parameters on open-iscsi web site. With only NODELAY fix, the performance drops, as you said.

MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The problem is in the ondemand governor, there is a periodic measurement of the CPU usage. This CPU usage is updated by the scheduler after every tick (basically, by adding 1 either to "idle" or to "user" or to "system"). So if the frequency of the governor is too high, the stat will be meaningless (as mostly no number have changed). So this patch checks that the measurements are separated by at least 10 ticks. It means that by default, stats will have about 5% error (20 ticks). Of course those numbers can be argued but, IMHO, they look sane. The patch also includes a small clean-up to check more explictly the result of the conversion from ns to µs being null. Let's note that (on x86) this has never been really needed before 2.6.13 because HZ was always 1000. Now that HZ can be 100, some CPU might be affected by this problem. For instance when HZ=100, the centrino ,which has a 10µs transition latency, would lead to the governor allowing to read stats every tick (10ms)!

Export a new function ieee80211_crypt_quiescing from ieee80211.

This is usually called during a driver's host crypto data structure free (module unload) path.

TKIP encryption Originally, TKIP encryption issues msdu + mpdu encryption on every fragment. Change the behavior to msdu encryption on the whole packet, then mpdu encryption on every fragment. 2. Avoid repeated fragmentation when !host_encrypt. We only need do fragmentation when using host encryption. Otherwise we only need pass the whole packet to driver, letting driver do the fragmentation. 3. change the txb->payload_size to correct value FW will use this value to determine whether to do fragmentation. If we pass the wrong value, fw may cut on the wrong bound which will make decryption fail when we do host encryption. NOTE: This requires changing drivers (hostap) that have extra_prefix_len used within them (structure member name change).

To implement this, ieee80211_xmit will now call the driver's is_queue_full to determine if the current priority queue is full. If so, NETDEV_TX_BUSY is returned to the kernel and no processing is done on the frame.

Miller" Date: Wed, 21 Sep 2005 21:49:32 -0700 Subject: [SPARC64]: Remove ktlb.S instruction patching. This was kind of ugly, and actually buggy. The bug was that we didn't handle a machine with memory starting > 4GB. If the 'prompmd' was allocated in physical memory > 4GB we'd croak because the obp_iaddr_patch and obp_daddr_patch things only supported a 32-bit physical address. So fix this by just loading the appropriate values from two variables in the kernel image, which is locked into the TLB and thus accesses to them can't cause a recursive TLB miss.

This was not such a big problem after all as most of the users of llc_alloc_frame were setting the correct dev, but this way code is reduced.

However, we dont have VDSO support in the ppc32 tree at this time. Introducing this define causes a number of other things to get built with the assumption of VDSO, thus causing the compile errors for ppc32. Until we have VDSO on ppc32 we will leave AT_SYSINFO_EHDR a ppc64 only define. Signed-off-by: Kumar K.

Added support to use the Book-E wrtee[i] instructions that allow modifying MSR[EE] atomically. Additionally, added get_irq_desc() macros to ppc32 to allow mask_irq(), unmask_irq(), and ack_irq() to be common between ppc32 & ppc64. Note: because 64-bit Book-E implementations only have a 32-bit MSR the macro's for Book-E need to come before the PPC64 macro's to ensure the right thing happends for 64-bit Book-E processors.

What happens is that a first device_attach() call (module insertion time) is on the way binding the device to a driver. Another thread calls bus_rescan_devices(). Now when bus_rescan_devices_helper() checks for dev->driver it is still NULL 'cos the the prior device_attach() is not yet finished. But as soon as the first one releases the dev->sem the second device_attach() tries to rebind the already bound device again. device_bind_driver() does this blindly which leads to a corrupt driver->klist_devices list (the device links itself, the head points to the device). Later a call to device_release_driver() sets dev->driver to NULL and breaks the link it has to itself on knode_driver. Rmmoding the driver later calls driver_detach() which leads to an endless loop 'cos the list head in klist_devices still points to the device. And since dev->driver is NULL it's stuck with the same device forever. Boom. And rmmod hangs. Very easy to reproduce with new-style pcmcia and a 16bit card. Just loop modprobe ;cardctl eject; rmmod . Easiest fix is to check if the device is already bound to a driver in device_bind_driver(). This avoids the double binding.

To demonstrate, rename your network device from eth0 to eth1. Your pci (or usb, or whatever) device will still have a 'net:eth0' link, except now it points to /sys/class/net/eth1. The attached patch makes sure the class symlink name changes when the class device name changes. It isn't 100% correct, it should be using sysfs_rename_link.

This works using normal 16550A serial ports as well as the FTDI driver version 1.4.0 (Linux 2.6.8) but stopped working with the change to "ensure RTS and DTR are raised when changing baudrate" introduced in version 1.4.1 (Linux 2.6.9).

Miller" Date: Thu, 22 Sep 2005 20:11:33 -0700 Subject: [SPARC64]: Rewrite bootup sequence. Instead of all of this cpu-specific code to remap the kernel to the correct location, use portable firmware calls to do this instead. What we do now is the following in position independant assembler: chosen_node = prom_finddevice("/chosen"); prom_mmu_ihandle_cache = prom_getint(chosen_node, "mmu"); vaddr = 4MB_ALIGN(current_text_addr()); prom_translate(vaddr, &paddr_high, &paddr_low, &mode); prom_boot_mapping_mode = mode; prom_boot_mapping_phys_high = paddr_high; prom_boot_mapping_phys_low = paddr_low; prom_map(-1, 8 * 1024 * 1024, KERNBASE, paddr_low); and that replaces the massive amount of by-hand TLB probing and programming we used to do here. The new code should also handle properly the case where the kernel is mapped at the correct address already (think: future kexec support). Consequently, the bulk of remap_kernel() dies as does the entirety of arch/sparc64/prom/map.S We try to share some strings in the PROM library with the ones used at bootup, and while we're here mark input strings to oplib.h routines with "const" when appropriate. There are many more simplifications now possible. For one thing, we can consolidate the two copies we now have of a lot of cpu setup code sitting in head.S and trampoline.S. This is a significant step towards CONFIG_DEBUG_PAGEALLOC support. Signed-off-by: David S.

On iSeries the Hypervisor has already inserted some ptes for us, and we simply have to detect that and bolt them. iSeries_hpte_bolt_or_insert() implements that logic. For the case of a non-existing pte we just call iSeries_hpte_insert(). This appears to work, although it's not entirely equivalent to the old code in iSeries_make_pte() which panicked if we got a secondary slot. Not sure if that's important. Finally we call iSeries_hpte_bolt_or_insert() from create_pte_mapping(), which is called from htab_initialize() for each lmb region.

Biederman" Date: Thu, 22 Sep 2005 21:43:46 -0700 Subject: [PATCH] suspend: cleanup calling of power off methods. In the lead up to 2.6.13 I fixed a large number of reboot problems by making the calling conventions consistent. Despite checking and double checking my work it appears I missed an obvious one. The S4 suspend code for PM_DISK_PLATFORM was also calling device_shutdown without setting system_state, and was not calling the appropriate reboot_notifier. This patch fixes the bug by replacing the call of device_suspend with kernel_poweroff_prepare. Various forms of this failure have been fixed and tracked for a while.

The report-back-error functionality was lost when buf_check_size was converted from macro to inline function. The return in the macro used to exit from the functions that include it, after the conversion it just exits from the inline function itself. The patch makes buf_check_size to return flag and all functions that use it check if they should perform the operation, or exit.

Inspecting the slab->nodeid field will not reflect that the page is now in use for the slabs of another node. This patch fixes that issue by adding a node field to free_block so that the caller can indicate which node currently uses a slab. Also removes the check for the current node from kmalloc_cache_node since the process may shift later to another node which may lead to an allocation on another node than intended.

It drives things like fans, i2c busses, real time clock, etc... The current kernel contains a very crude driver that doesn't do much more than reading the real time clock synchronously. This is a completely rewritten driver that provides interrupt based command queuing, a userland interface, and an i2c/smbus driver for accessing the devices hanging off the SMU i2c busses like temperature sensors. This driver is a basic block for upcoming work on thermal control for those machines, among others.

I had an issue on ia64 where I got a bug in kernel/workqueue because kzalloc returned a NULL pointer due to the task structure getting too big for the slab allocator. Usually these cases are caught by the kmalloc macro in include/linux/slab.h. Compilation will fail if a too big value is passed to kmalloc. However, kzalloc uses __kmalloc which has no check for that. This patch makes __kmalloc bug if a too large entity is requested.

While actually, on general protection faults, that address is not accessible, so we'd better assume we couldn't satisfy the fault. Currently instead we think we've fixed it, so we go back, retry the instruction and fault again endlessly. This leads to the kernel hanging when doing copy_from_user(dest, -1, ...) in TT mode, since reading *(-1) causes a GFP, and we don't support kernel preemption.

Problem: In some circumstances, bd_claim() is returning the wrong error code. If we try to swapon an unused block device that isn't swap formatted, we get -EINVAL. But if that same block device is already mounted, we instead get -EBUSY, even though it still isn't a valid swap device. This issue came up on the busybox list trying to get the error message from "swapon -a" right. If a swap device is already enabled, we get -EBUSY, and we shouldn't report this as an error. But we can't distinguish the two -EBUSY conditions, which are very different errors. In the code, bd_claim() returns either 0 or -EBUSY, but in this case busy means "somebody other than sys_swapon has already claimed this", and _that_ means this block device can't be a valid swap device. So return -EINVAL there.

Prior to that, tcp_retrans_try_collapse() was the only way for that to happen on the retransmission path. When this happens with Reno, it is possible for sasked_out to become invalid because it is only an estimate and not tied to any particular packet on the retransmission queue. Therefore we need to adjust sacked_out as well as left_out in the Reno case. The following patch does exactly that.

It cannot be reasonably split up in multiple fixes, since all bugs interact with each other and affect the same function: Bug #1: The event cache code cannot be called while a lock is held. Therefore, the call to ip_conntrack_event_cache() within ip_ct_refresh_acct() needs to be moved outside of the locked section. This fixes a number of 2.6.14-rcX oops and deadlock reports. Bug #2: We used to call ct_add_counters() for unconfirmed connections without holding a lock. Since the add operations are not atomic, we could race with another CPU. Bug #3: ip_ct_refresh_acct() lost REFRESH events in some cases where refresh (and the corresponding event) are desired, but no accounting shall be performed. Both, evenst and accounting implicitly depended on the skb parameter bein non-null. We now re-introduce a non-accounting "ip_ct_refresh()" variant to explicitly state the desired behaviour.

This also provides an FSM hook for retrying an rpcbind with a different rpcbind protocol version. We'll use this later to try multiple rpcbind protocol versions when binding. To enable this, expose the RPC error code returned during a portmap request to the FSM so it can make some decision about how to report, retry, or fail the request.

Provide a debug setting for transports that is separate from RPCDBG_XPRT. Eliminate xprt_default_timeout(). Provide block comments for exposed interfaces in xprt.c, and eliminate the useless obvious comments. Convert printk's to dprintk's. Test-plan: Compile kernel with CONFIG_NFS enabled.

Compiler optimization removes unneeded code from xs_sendpages, as this function is now called with some constant arguments. We can now cleanly perform transport protocol-specific return code testing and error recovery in each path. Test-plan: Millions of fsx operations. Performance characterization such as "sio" or "iozone". Examine oprofile results for any changes before and after this patch is applied.

The first method we abstract is the one that serializes access to the RPC transport to prevent the bytes from different requests from mingling together. This method provides proper request serialization and the opportunity to prevent new requests from being started because the transport is congested. The normal situation is for the transport to handle congestion control itself. Although NFS over UDP was first, it has been recognized after years of experience that having the transport provide congestion control is much better than doing it in the RPC client. Thus TCP, and probably every future transport implementation, will use the default method, xprt_lock_write, provided in xprt.c, which does not provide any kind of congestion control. UDP can continue using the xprt.c-provided Van Jacobson congestion avoidance implementation. Test-plan: Use WAN simulation to cause sporadic bursty packet loss. Look for significant regression in performance or client stability.

They take a path relative to the rpc_pipefs root and thus need to perform a full lookup. If you look at debugfs or usbfs they always store the dentry for directories they created and thus can pass in a dentry + single pathname component pair into their equivalents of the above functions. And in fact rpc_pipefs actually stores a dentry for all but one component so this change not only simplifies the core rpc_pipe code but also the callers. Unfortuntately this code path is only used by the NFS4 idmapper and AUTH_GSSAPI for which I don't have a test enviroment. Could someone give it a spin?

All devices "consume" the indicated address space. If the resource is marked as a "producer", the range is also passed on to child devices. We currently ignore this flag when setting up MMIO and I/O port windows for PCI root bridges, so we could mistakenly interpret a "consumed-only" range, like CSR space for the device itself, as a window that is routed to children.

One is that we forgot to set the "secondary" bit in the hash PTEs when hashing a huge page in the secondary bucket (fortunately very rare).

Miller" Date: Sun, 25 Sep 2005 16:46:57 -0700 Subject: [SPARC64]: Add CONFIG_DEBUG_PAGEALLOC support. The trick is that we do the kernel linear mapping TLB miss starting with an instruction sequence like this: ba,pt %xcc, kvmap_load xor %g2, %g4, %g5 succeeded by an instruction sequence which performs a full page table walk starting at swapper_pg_dir. We first take over the trap table from the firmware. Then, using this constant PTE generation for the linear mapping area above, we build the kernel page tables for the linear mapping. After this is setup, we patch that branch above into a "nop", which will cause TLB misses to fall through to the full page table walk. With this, the page unmapping for CONFIG_DEBUG_PAGEALLOC is trivial. Signed-off-by: David S.

This is enough to build a 32-bit powermac kernel with ARCH=powerpc. For now we are getting some unmerged files from arch/ppc/kernel and arch/ppc/syslib, or arch/ppc64/kernel.

Miller" Date: Mon, 26 Sep 2005 00:32:17 -0700 Subject: [SPARC64]: Probe D/I/E-cache config and use. At boot time, determine the D-cache, I-cache and E-cache size and line-size. Use them in cache flushes when appropriate. This change was motivated by discovering that the D-cache on UltraSparc-IIIi and later are 64K not 32K, and the flushes done by the Cheetah error handlers were assuming a 32K size. There are still some pieces of code that are hard coding things and will need to be fixed up at some point. While we're here, fix the D-cache and I-cache parity error handlers to run with interrupts disabled, and when the trap occurs at trap level > 1 log the event via a counter displayed in /proc/cpuinfo.

But this bit only controls the routing of card functional interrupts, not the CSC interrupts which are used for interrupt probing. A bad side effect of messing with this register in yenta_probe_irq() is that it can lead to irq storms if a card is inserted and already powered by the BIOS. Usage in yenta_sock_init() and yenta_config_init() seem to be fishy as well.

Date: Mon, 26 Sep 2005 13:01:03 -0700 Subject: [IB] uverbs: Close some exploitable races Al Viro pointed out that the current IB userspace verbs interface allows userspace to cause mischief by closing file descriptors before we're ready, or issuing the same command twice at the same time. This patch closes those races, and fixes other obvious problems such as a module reference leak. Some other interface bogosities will require an ABI change to fix properly, so I'm deferring those fixes until 2.6.15.

This causes a huge performance penalty, since for every packet you iterate the nat code, even if you don't want it. This patch splits iptable_nat.ko into the NAT core (ip_nat.ko) and the iptables frontend (iptable_nat.ko). Threfore, ip_conntrack_netlink.ko will only pull ip_nat.ko, but not the frontend. ip_nat.ko will "only" allocate some resources, but not affect runtime performance. This separation is also a nice step in anticipation of new packet filters (nf-hipac, ipset, pkttables) being able to use the NAT core. Signed-off-by: Harald Welte Signed-off-by: David S.

There are a few adapters that are capable of creating devices with this large of a capacity, but now that we have the large fib support in, the management applications will be capable of generating them. The problem is, once they are created, the driver will not be able to access the devices correctly without this patch.

In the rare instances where the adapter, or the motherboard, is misbehaving; driver initialization or shutdown becomes problematic. By introducing a 3 minute timeout on the first interrupt driven command during initialization, or the issuance of the adapter shutdown command during driver unload, we can resolve the lockup problems induced by common (but rare) hardware misbehaviors. The timeout during initialization, should it occur, is accompanied by a message presented to the console and the logs indicating that the user should inspect and resolve problems with interrupt routing.

On normal builds it's always there, of course, but on O= it's created (by generic code) too late - when we get to asm-offset.h. We used to get away with that by accident - creation of include/asm-arm/arch symlink creates include/asm-arm and it happened to go before maketools. However, we did not have such dependency, so that luck didn't last - now maketools is picked first and we are screwed. Both the symlink and maketools are prerequisites of the same target (archprepare). This fix is obvious - make the latter explicitly depend on the former and be done with that.

MAC_RX_MODE reset must be done before setting up the MAC_MODE register on 5705_PLUS chips or the chip will stop receiving after a while. The MAC_RX_MODE reset is needed to prevent intermittently losing the first receive packet on serdes chips. 2. Skip MAC loopback test on 5780 because of hardware errata. Normal traffic including PHY loopback is not affected by the errata. 3. PHY loopback fails intermittently on 5708S and this is fixed by putting the PHY in loopback mode first before programming the MAC mode register. A MAC_RX_MODE reset is also added. 4.

The first issue was that __module_get failed at the BUG_ON check at the top of the routine (checking that my module reference count was not zero) when I created the first socket. When sk_alloc() is called, my module reference count was still 0. When I looked at why sctp didn't have this problem, I discovered that sctp creates a control socket during module init (when the module ref count is not 0), which keeps the reference count non-zero. This section has been updated to address the point Stephen raised about checking the return value of try_module_get(). The next problem arose when my socket init routine returned an error. This resulted in my module reference count being decremented below 0. My socket ops->release routine was also being called. The issue here is that sock_release() calls the ops->release routine and decrements the ref count if sock->ops is not NULL. Since the socket probably didn't get correctly initialized, this should not be done, so we will set sock->ops to NULL because we will not call try_module_get(). While searching for another bug, I also noticed that sys_accept() has a possibility of doing a module_put() when it did not do an __module_get so I re-ordered the call to security_socket_accept().

From: Oliver Dawid we found a bug in net/appletalk/ddp.c concerning broadcast packets. In kernel 2.4 it was working fine. The bug first occured 4 years ago when switching to new SNAP layer handling. This bug can be splitted up into a sending(1) and reception(2) problem: Sending(1) In kernel 2.4 broadcast packets were sent to a matching ethernet device and atalk_rcv() was called to receive it as "loopback" (so loopback packets were shortcutted and handled in DDP layer). When switching to the new SNAP structure, this shortcut was removed and the loopback packet was send to SNAP layer. The author forgot to replace the remote device pointer by the loopback device pointer before sending the packet to SNAP layer (by calling ddp_dl->request() ) therfor the packet was not sent back by underlying layers to ddp's atalk_rcv(). Reception(2) In atalk_rcv() a packet received by this loopback mechanism contains now the (rigth) loopback device pointer (in Kernel 2.4 it was the (wrong) remote ethernet device pointer) and therefor no matching socket will be found to deliver this packet to. Because a broadcast packet should be send to the first matching socket (as it is done in many other protocols (?)), we removed the network comparison in broadcast case. Below you will find a patch to correct this bug. Its diffed to kernel 2.6.14-rc1 Signed-off-by: Arnaldo Carvalho de Melo Signed-off-by: David S.

In doing this removed support for the BEGIN_FTR_SECTION/END_FTR_SECTION macros in C code since they dont compile correctly. C code should use cpu_has_feature(). This is based on Arnd Bergmann's initial patch.

Additionally, made call_setup_cpu check to see if the cpu_setup pointer is NULL or not before calling the function. This lets remove the dummy cpu_setup calls that just return.

For architectures without __HAVE_ARCH_MULTIPLE_ZERO_PAGE, move_pte becomes a noop. From: Hugh Dickins Fix nasty little bug we've missed in Nick's mremap move ZERO_PAGE patch. The "pte" at that point may be a swap entry or a pte_file entry: we must check pte_present before perhaps corrupting such an entry. Patch below against 2.6.14-rc2-mm1, but the same bug is in 2.6.14-rc2's mm/mremap.c, and more dangerous there since it's affecting all arches: I think the safest course is to send Nick's patch and Yoichi's build fix and this fix (build tested) on to Linus - so only MIPS can be affected.

The patch attempts to fix the races in dentry's fid management. Dentries don't keep the opened fids anymore, they are moved to the file structs. Ideally there should be no more than one fid with fidcreate equal to zero in the dentry's list of fids. v9fs_fid_create initializes the important fields (fid, fidcreated) before v9fs_fid is added to the list. v9fs_fid_lookup returns only fids that are not created by v9fs_create. v9fs_fid_get_created returns the fid created by the same process by v9fs_create (if any) and removes it from dentry's list Signed-off-by: Latchesar Ionkov Cc: Eric Van Hensbergen Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds diff --git a/fs/9p/fid.c b/fs/9p/fid.c index 821c9c4..d95f862 100644 --- a/fs/9p/fid.c +++ b/fs/9p/fid.c @@ -71,21 +71,28 @@ static int v9fs_fid_insert(struct v9fs_fid *fid, struct dentry *dentry) * */ -struct v9fs_fid *v9fs_fid_create(struct dentry *dentry) +struct v9fs_fid *v9fs_fid_create(struct dentry *dentry, + struct v9fs_session_info *v9ses, int fid, int create) { struct v9fs_fid *new;

While the queue_if_no_path variable is correctly set to 1, the saved_queue_if_no_path gets set to 0. When the device is subsequently made live (resumed), the saved value (0) always overwrites the live value (1) so the option *always* gets turned off. The fix adds a parameter to the queue_if_no_path() function to indicate whether the previous value should be preserved or not - if not, as when the device is being set up, the saved value is set to the new value (1).

This makes SUID binaries easier to support without going as far as labelling keys and key targets using the LSM facilities. This patch adds a second "pointer type" to key structures (struct key_ref *) that can have the bottom bit of the address set to indicate the possession of a key. This is propagated through searches from the keyring to the discovered key. It has been made a separate type so that the compiler can spot attempts to dereference a potentially incorrect pointer. The "possession" attribute can't be attached to a key structure directly as it's not an intrinsic property of a key. Pointers to keys have been replaced with struct key_ref *'s wherever possession information needs to be passed through. This does assume that the bottom bit of the pointer will always be zero on return from kmem_cache_alloc(). The key reference type has been made into a typedef so that at least it can be located in the sources, even though it's basically a pointer to an undefined type. I've also renamed the accessor functions to be more useful, and all reference variables should now end in "_ref".

One is via qc->complete_fn() callback and the + other is completion qc->waiting. qc->complete_fn() callback + is the asynchronous path used by normal SCSI translated + commands and qc->waiting is the synchronous (issuer sleeps in + process context) path used by internal commands. + + + Once initialization is complete, host_set lock is acquired + and the qc is issued. + + + + + SCSI commands + + + All libata drivers use ata_scsi_queuecmd() as + hostt->queuecommand callback. scmds can either be simulated + or translated. No qc is involved in processing a simulated + scmd. The result is computed right away and the scmd is + completed. + + + For a translated scmd, ata_qc_new_init() is invoked to + allocate a qc and the scmd is translated into the qc. SCSI + midlayer's completion notification function pointer is stored + into qc->scsidone. + + + qc->complete_fn() callback is used for completion + notification. ATA commands use ata_scsi_qc_complete() while + ATAPI commands use atapi_qc_complete(). Both functions end up + calling qc->scsidone to notify upper layer when the qc is + finished. After translation is completed, the qc is issued + with ata_qc_issue(). + + + Note that SCSI midlayer invokes hostt->queuecommand while + holding host_set lock, so all above occur while holding + host_set lock. + + + + + + + + How commands are processed + + Depending on which protocol and which controller are used, + commands are processed differently. For the purpose of + discussion, a controller which uses taskfile interface and all + standard callbacks is assumed. + + + Currently 6 ATA command protocols are used. They can be + sorted into the following four categories according to how + they are processed. + + + + ATA NO DATA or DMA + + + ATA_PROT_NODATA and ATA_PROT_DMA fall into this category. + These types of commands don't require any software + intervention once issued. Device will raise interrupt on + completion. + + + + + ATA PIO + + + ATA_PROT_PIO is in this category. libata currently + implements PIO with polling. ATA_NIEN bit is set to turn + off interrupt and pio_task on ata_wq performs polling and + IO. + + + + + ATAPI NODATA or DMA + + + ATA_PROT_ATAPI_NODATA and ATA_PROT_ATAPI_DMA are in this + category. packet_task is used to poll BSY bit after + issuing PACKET command. Once BSY is turned off by the + device, packet_task transfers CDB and hands off processing + to interrupt handler. + + + + + ATAPI PIO + + + ATA_PROT_ATAPI is in this category. ATA_NIEN bit is set + and, as in ATAPI NODATA or DMA, packet_task submits cdb. + However, after submitting cdb, further processing (data + transfer) is handed off to pio_task. + + + + + + + How commands are completed + + Once issued, all qc's are either completed with + ata_qc_complete() or time out. For commands which are handled + by interrupts, ata_host_intr() invokes ata_qc_complete(), and, + for PIO tasks, pio_task invokes ata_qc_complete(). In error + cases, packet_task may also complete commands. + + + ata_qc_complete() does the following. + + + + + + + DMA memory is unmapped. + + + + + + ATA_QCFLAG_ACTIVE is clared from qc->flags. + + + + + + qc->complete_fn() callback is invoked. If the return value of + the callback is not zero.

One + exception is short-circuit path in #3 which is used by + atapi_qc_complete(). + + + For all non-ATAPI commands, whether it fails or not, almost + the same code path is taken and very little error handling + takes place. A qc is completed with success status if it + succeeded, with failed status otherwise. + + + However, failed ATAPI commands require more handling as + REQUEST SENSE is needed to acquire sense data. If an ATAPI + command fails, ata_qc_complete() is invoked with error status, + which in turn invokes atapi_qc_complete() via + qc->complete_fn() callback. + + + This makes atapi_qc_complete() set scmd->result to + SAM_STAT_CHECK_CONDITION, complete the scmd and return 1. As + the sense data is empty but scmd->result is CHECK CONDITION, + SCSI midlayer will invoke EH for the scmd, and returning 1 + makes ata_qc_complete() to return without deallocating the qc. + This leads us to ata_scsi_error() with partially completed qc. + + + + + ata_scsi_error() + + ata_scsi_error() is the current hostt->eh_strategy_handler() + for libata. As discussed above, this will be entered in two + cases - timeout and ATAPI error completion. This function + calls low level libata driver's eng_timeout() callback, the + standard callback for which is ata_eng_timeout(). It checks + if a qc is active and calls ata_qc_timeout() on the qc if so. + Actual error handling occurs in ata_qc_timeout(). + + + If EH is invoked for timeout, ata_qc_timeout() stops BMDMA and + completes the qc. Note that as we're currently in EH, we + cannot call scsi_done. As described in SCSI EH doc, a + recovered scmd should be either retried with + scsi_queue_insert() or finished with scsi_finish_command(). + Here, we override qc->scsidone with scsi_finish_command() and + calls ata_qc_complete(). + + + If EH is invoked due to a failed ATAPI qc, the qc here is + completed but not deallocated. The purpose of this + half-completion is to use the qc as place holder to make EH + code reach this place. This is a bit hackish, but it works. + + + Once control reaches here, the qc is deallocated by invoking + __ata_qc_complete() explicitly. Then, internal qc for REQUEST + SENSE is issued. Once sense data is acquired, scmd is + finished by directly invoking scsi_finish_command() on the + scmd. Note that as we already have completed and deallocated + the qc which was associated with the scmd, we don't need + to/cannot call ata_qc_complete() again. + + + + + Problems with the current EH + + + + + + Error representation is too crude. Currently any and all + error conditions are represented with ATA STATUS and ERROR + registers. Errors which aren't ATA device errors are treated + as ATA device errors by setting ATA_ERR bit. Better error + descriptor which can properly represent ATA and other + errors/exceptions is needed. + + + + + + When handling timeouts, no action is taken to make device + forget about the timed out command and ready for new commands. + + + + + + EH handling via ata_scsi_error() is not properly protected + from usual command processing. On EH entrance, the device is + not in quiescent state. Timed out commands may succeed or + fail any time. pio_task and atapi_task may still be running. + + + + + + Too weak error recovery. Devices / controllers causing HSM + mismatch errors and other errors quite often require reset to + return to known state. Also, advanced error handling is + necessary to support features like NCQ and hotplug. + + + + + + ATA errors are directly handled in the interrupt handler and + PIO errors in pio_task. This is problematic for advanced + error handling for the following reasons. + + + First, advanced error handling often requires context and + internal qc execution. + + + Second, even a simple failure (say, CRC error) needs + information gathering and could trigger complex error handling + (say, resetting & reconfiguring). Having multiple code + paths to gather information, enter EH and trigger actions + makes life painful. + + + Third, scattered EH code makes implementing low level drivers + difficult. Low level drivers override libata callbacks. If + EH is scattered over several places, each affected callbacks + should perform its part of error handling.

Miller" Date: Wed, 28 Sep 2005 20:41:45 -0700 Subject: [SPARC64]: Fix fault handling in unaligned trap handler. We were not calling kernel_mna_trap_fault() correctly. Instead of being fancy, just return 0 vs. -EFAULT from the assembler stubs, and handle that return value as appropriate. Create an "__retl_efault" stub for assembler exception table entries and use it where possible. Signed-off-by: David S.

Instead of doing byte-at-a-time user accesses to figure out where the fault occurred, read the saved fault_address from the current thread structure. For the sake of defensive programming, if the fault_address does not fall into the user buffer range, simply assume the whole area faulted. This will cause the fixup for copy_from_user() to clear the entire kernel side buffer. Signed-off-by: David S.

Miller" Date: Thu, 29 Sep 2005 17:07:20 -0700 Subject: [TCP]: Revert 6b251858d377196b8cea20e65cae60f584a42735 But retain the comment fix. Alexey Kuznetsov has explained the situation as follows: -------------------- I think the fix is incorrect. Look, the RFC function init_cwnd(mss) is not continuous: f.e. for mss=1095 it needs initial window 1095*4, but for mss=1096 it is 1096*3. We do not know exactly what mss sender used for calculations. If we advertised 1096 (and calculate initial window 3*1096), the sender could limit it to some value < 1096 and then it will need window his_mss*4 > 3*1096 to send initial burst. See? So, the honest function for inital rcv_wnd derived from tcp_init_cwnd() is: init_rcv_wnd(mss)= min { init_cwnd(mss1)*mss1 for mss1 <= mss } It is something sort of: if (mss < 1096) return mss*4; if (mss < 1096*2) return 1096*4; return mss*2; (I just scrablled a graph of piece of paper, it is difficult to see or to explain without this) I selected it differently giving more window than it is strictly required. Initial receive window must be large enough to allow sender following to the rfc (or just setting initial cwnd to 2) to send initial burst. But besides that it is arbitrary, so I decided to give slack space of one segment. Actually, the logic was: If mss is low/normal (<=ethernet), set window to receive more than initial burst allowed by rfc under the worst conditions i.e. mss*4. This gives slack space of 1 segment for ethernet frames. For msses slighlty more than ethernet frame, take 3. Try to give slack space of 1 frame again. If mss is huge, force 2*mss. No slack space. Value 1460*3 is really confusing. Minimal one is 1096*2, but besides that it is an arbitrary value. It was meant to be ~4096. 1460*3 is just the magic number from RFC, 1460*3 = 1095*4 is the magic :-), so that I guess hands typed this themselves. -------------------- Signed-off-by: David S.

This known problem is even mentioned in the comments above tcp_grow_window() in tcp_input.c, specifically: ... * The scheme does not work when sender sends good segments opening * window and then starts to feed us spagetti. But it should work * in common situations. Otherwise, we have to rely on queue collapsing. ... When the sender gives full sized frames, the "struct sk_buff" overhead from each packet is small. So we'll advertize a larger window. If the sender moves to a mode where small segments are sent, this ratio becomes tilted to the other extreme and we start overrunning the socket buffer space. tcp_clamp_window() tries to address this, but it's clamping of tp->window_clamp is a wee bit too aggressive for this particular case.

Currently, IP sockets are classified by SELinux as being either TCP, UDP or 'Raw', the latter being a default for IP socket that is not TCP or UDP. The classification code is out of date and uses only the socket type parameter to socket(2) to determine the class of IP socket. So, any socket created with SOCK_STREAM will be classified by SELinux as TCP, and SOCK_DGRAM as UDP. Also, other socket types such as SOCK_SEQPACKET and SOCK_DCCP are currently ignored by SELinux, which classifies them as generic sockets, which means they don't even get basic IP level checking. This patch changes the SELinux IP socket classification logic, so that only an IPPROTO_IP protocol value passed to socket(2) classify the socket as TCP or UDP. The patch also drops the check for SOCK_RAW and converts it into a default, so that socket types like SOCK_DCCP and SOCK_SEQPACKET are classified as SECCLASS_RAWIP_SOCKET (instead of generic sockets). Note that protocol-specific support for SCTP, DCCP etc. is not addressed here, we're just getting these protocols checked at the IP layer. This fixes a reported problem where SCTP sockets were being recognized as generic SELinux sockets yet still being passed in one case to an IP level check, which then fails for generic sockets. It will also fix bugs where any SOCK_STREAM socket is classified as TCP or any SOCK_DGRAM socket is classified as UDP. This patch also unifies the way IP sockets classes are determined in selinux_socket_bind(), so we use the already calculated value instead of trying to recalculate it.

Indeed, hostfs i_op->truncate doesn't do anything. But hostfs_setattr() -> set_attr() correctly detects ATTR_SIZE and calls truncate() on the host. So we should be safe (using ftruncate() may be better, in case the file is unlinked on the host, but we aren't sure to have the file open for writing, and reopening it would cause the same races; plus nobody should expect UML to be so careful). So, the warning is wrong, because the current implementation is working. Al, am I correct, and can the warning be therefore dropped?

This error message is bogus for two reasons. First, it can never occur given that current code takes care to initialize IOC4 in such a way that these "unknown" interrupts could never occur. Second, this code fails to take into account that other drivers can share the IOC4 interrupt mechanism through SA_SHIRQ, and thus this driver is not in-fact "all-knowing". Finally, this error message triggers every time some "unknown" interrupt occurs -- it's not rate limited or repetition limited in any way, thereby effectively denying use of the console device. Given its bogosity in the first place, it's best to just get rid of it entirely.

Here is a quick fix for this. The right fix obviously is to have cpu_to_node[bsp] setup early for numa_init_array(). The following patch will fix the problem now, and the code can stay on even when cpu_to_node{BP] gets fixed early correctly. Thanks to Petr for access to his box.

There is no need for the jfs code setting the I_DIRTY bits in i_state. I am ashamed that the code ever did this, and surprised it hasn't been noticed until now. 2. Make sure special inodes are on an inode hash list. If the inodes are unhashed, __mark_inode_dirty will fail to put the inode on the superblock's dirty list, and the data will not be flushed under memory pressure. 3. Force writing journal data to disk when metapage_writepage is unable to write a metadata page due to pending journal I/O.

I've found the problem in general. It affects any 64-bit architecture. The problem occurs when you change the system time. Suppose that when you boot your system clock is forward by a day. This gets recorded down in skb_tv_base. You then wind the clock back by a day. From that point onwards the offset will be negative which essentially overflows the 32-bit variables they're stored in. In fact, why don't we just store the real time stamp in those 32-bit variables? After all, we're not going to overflow for quite a while yet. When we do overflow, we'll need a better solution of course. Signed-off-by: Herbert Xu Signed-off-by: David S.

Test for VIA K8T800 north bridge instead of AMD K8 HyperTransport bridge based on new information from Andi Kleen. The AMD HyperTransport interface is not responsible for PCI transactions and so the re-ordering is more likely done by the VIA north bridge. This code is subject to change if we get more information from AMD or VIA. PCI Express devices are excluded from doing the read flush since all chipsets in the write_reorder list are PCI chipsets.

As INET_MATCH first comparison uses inet_sk(__sk)->daddr, wich is far away from the begining of "struct sock", it has to bring into CPU cache cold cache line. Each iteration has to use at least 2 cache lines. This can be problematic if some chains are very long. 2) The goal ----------- The idea I had is to change things so that INET_MATCH() may return FALSE in 99% of cases only using the data already in the CPU cache, using one cache line per iteration. 3) Description of the patch --------------------------- Adds a new 'unsigned int skc_hash' field in 'struct sock_common', filling a 32 bits hole on 64 bits platform. struct sock_common { unsigned short skc_family; volatile unsigned char skc_state; unsigned char skc_reuse; int skc_bound_dev_if; struct hlist_node skc_node; struct hlist_node skc_bind_node; atomic_t skc_refcnt; + unsigned int skc_hash; struct proto *skc_prot; }; Store in this 32 bits field the full hash, not masked by (ehash_size - 1) Using this full hash as the first comparison done in INET_MATCH permits us immediatly skip the element without touching a second cache line in case of a miss. Suppress the sk_hashent/tw_hashent fields since skc_hash (aliased to sk_hash and tw_hash) already contains the slot number if we mask with (ehash_size - 1) File include/net/inet_hashtables.h 64 bits platforms : #define INET_MATCH(__sk, __hash, __cookie, __saddr, __daddr, __ports, __dif)\ (((__sk)->sk_hash == (__hash)) ((*((__u64 *)&(inet_sk(__sk)->daddr)))== (__cookie)) && \ ((*((__u32 *)&(inet_sk(__sk)->dport))) == (__ports)) && \ (!((__sk)->sk_bound_dev_if) || ((__sk)->sk_bound_dev_if == (__dif)))) 32bits platforms: #define TCP_IPV4_MATCH(__sk, __hash, __cookie, __saddr, __daddr, __ports, __dif)\ (((__sk)->sk_hash == (__hash)) && \ (inet_sk(__sk)->daddr == (__saddr)) && \ (inet_sk(__sk)->rcv_saddr == (__daddr)) && \ (!((__sk)->sk_bound_dev_if) || ((__sk)->sk_bound_dev_if == (__dif)))) - Adds a prefetch(head->chain.first) in __inet_lookup_established()/__tcp_v4_check_established() and __inet6_lookup_established()/__tcp_v6_check_established() and __dccp_v4_check_established() to bring into cache the first element of the list, before the {read|write}_lock(&head->lock); Signed-off-by: Eric Dumazet Acked-by: Arnaldo Carvalho de Melo Signed-off-by: David S.

Sorry, no exact revison and no more debugging > yet since it'a a production gateway. The breakage is caused by the change to use the CB area for flagging whether a packet has been queued due to proxy_delay. This area gets cleared every time arp_rcv gets called. Unfortunately packets delayed due to proxy_delay also go through arp_rcv when they are reprocessed. In fact, I can't think of a reason why delayed proxy packets should go through netfilter again at all. So the easiest solution is to bypass that and go straight to arp_process. This is essentially what would've happened before netfilter support was added to ARP. Signed-off-by: Herbert Xu Signed-off-by: David S.

These were only used for hostap_cs and only for tracking whether any of the netdevs were UP. This information is already available from local->num_dev_open, so there is not need for the special open/close handler. Let's get rid of these handlers. In addition to cleaning up the code, this fixes a module refcounting issue for hostap_cs where ejecting the card while any of the netdevs were open did not decrement refcount properly.

In case of OSN qeth communicates with the type-OSN OSA-card on one hand, and with the CCL-kernel-component Network Device Handler (NDH) on the other.

Currently it runs in DMA mode on a 6081 chip. The 5xxx series parts are not yet DMA capable in this driver because the registers have differences that haven't been accounted for yet. Basically, I'm focused on the 6xxx series right now. I apologize for those seeing problems on the 5xxx series, I've not had a chance to look at those problems yet. For those curious, the previous bug causing the SCSI timeout and subsequent panics was caused by an improper clear of hc_irq_cause in mv_host_intr(). This version is running well in my environment (6081 chips, with/without SW raid1) and is showing equal or better performance compared to the Marvell driver (mv_sata) in my initial tests (timed dd's of reads/writes to/from memory/disk). I still need to look at the causes of occasional problems such as this: ata11: translating stat 0x35 err 0x00 to sense ata11: status=0x35 { DeviceFault SeekComplete CorrectedError Error } SCSI error : <10 0 0 0> return code = 0x8000002 Current sda: sense key Hardware Error end_request: I/O error, dev sda, sector 3155010 and this, seen at init time: ATA: abnormal status 0x80 on port 0xE093911C but they aren't showstoppers.

Where + explicit distinction between error and exception is necessary, the + term 'non-error exception' is used. + + + + Exception categories + + Exceptions are described primarily with respect to legacy + taskfile + bus master IDE interface. If a controller provides + other better mechanism for error reporting, mapping those into + categories described below shouldn't be difficult. + + + + In the following sections, two recovery actions - reset and + reconfiguring transport - are mentioned. These are described + further in . + + + + HSM violation + + This error is indicated when STATUS value doesn't match HSM + requirement during issuing or excution any ATA/ATAPI command. + + + + Examples + + + + ATA_STATUS doesn't contain !BSY && DRDY && !DRQ while trying + to issue a command. + + + + + + !BSY && !DRQ during PIO data transfer. + + + + + + DRQ on command completion. + + + + + + !BSY && ERR after CDB tranfer starts but before the + last byte of CDB is transferred. ATA/ATAPI standard states + that "The device shall not terminate the PACKET command + with an error before the last byte of the command packet has + been written" in the error outputs description of PACKET + command and the state diagram doesn't include such + transitions. + + + + + + + In these cases, HSM is violated and not much information + regarding the error can be acquired from STATUS or ERROR + register. IOW, this error can be anything - driver bug, + faulty device, controller and/or cable. + + + + As HSM is violated, reset is necessary to restore known state. + Reconfiguring transport for lower speed might be helpful too + as transmission errors sometimes cause this kind of errors. + + + + + ATA/ATAPI device error (non-NCQ / non-CHECK CONDITION) + + + These are errors detected and reported by ATA/ATAPI devices + indicating device problems. For this type of errors, STATUS + and ERROR register values are valid and describe error + condition. Note that some of ATA bus errors are detected by + ATA/ATAPI devices and reported using the same mechanism as + device errors. Those cases are described later in this + section. + + + + For ATA commands, this type of errors are indicated by !BSY + && ERR during command execution and on completion. + + + For ATAPI commands, + + + + + + !BSY && ERR && ABRT right after issuing PACKET + indicates that PACKET command is not supported and falls in + this category. + + + + + + !BSY && ERR(==CHK) && !ABRT after the last + byte of CDB is transferred indicates CHECK CONDITION and + doesn't fall in this category. + + + + + + !BSY && ERR(==CHK) && ABRT after the last byte + of CDB is transferred *probably* indicates CHECK CONDITION and + doesn't fall in this category. + + + + + + + Of errors detected as above, the followings are not ATA/ATAPI + device errors but ATA bus errors and should be handled + according to . + + + + + + CRC error during data transfer + + + This is indicated by ICRC bit in the ERROR register and + means that corruption occurred during data transfer. Upto + ATA/ATAPI-7, the standard specifies that this bit is only + applicable to UDMA transfers but ATA/ATAPI-8 draft revision + 1f says that the bit may be applicable to multiword DMA and + PIO. + + + + + + ABRT error during data transfer or on completion + + + Upto ATA/ATAPI-7, the standard specifies that ABRT could be + set on ICRC errors and on cases where a device is not able + to complete a command.

So, this is kind of + gray area. Some heuristics are needed here. + + + + + + + + ATA/ATAPI device errors can be further categorized as follows. + + + + + + Media errors + + + This is indicated by UNC bit in the ERROR register. ATA + devices reports UNC error only after certain number of + retries cannot recover the data, so there's nothing much + else to do other than notifying upper layer. + + + READ and WRITE commands report CHS or LBA of the first + failed sector but ATA/ATAPI standard specifies that the + amount of transferred data on error completion is + indeterminate, so we cannot assume that sectors preceding + the failed sector have been transferred and thus cannot + complete those sectors successfully as SCSI does. + + + + + + Media changed / media change requested error + + + <<TODO: fill here>> + + + + + Address error + + + This is indicated by IDNF bit in the ERROR register. + Report to upper layer. + + + + + Other errors + + + This can be invalid command or parameter indicated by ABRT + ERROR bit or some other error condition. Note that ABRT + bit can indicate a lot of things including ICRC and Address + errors. Heuristics needed. + + + + + + + + Depending on commands, not all STATUS/ERROR bits are + applicable. These non-applicable bits are marked with + "na" in the output descriptions but upto ATA/ATAPI-7 + no definition of "na" can be found. However, + ATA/ATAPI-8 draft revision 1f describes "N/A" as + follows. + + +
+ + 3.2.3.3a N/A + + + A keyword the indicates a field has no defined value in + this standard and should not be checked by the host or + device. N/A fields should be cleared to zero. + + + + +
+ + + So, it seems reasonable to assume that "na" bits are + cleared to zero by devices and thus need no explicit masking. + + + + + + ATAPI device CHECK CONDITION + + + ATAPI device CHECK CONDITION error is indicated by set CHK bit + (ERR bit) in the STATUS register after the last byte of CDB is + transferred for a PACKET command. For this kind of errors, + sense data should be acquired to gather information regarding + the errors. REQUEST SENSE packet command should be used to + acquire sense data. + + + + Once sense data is acquired, this type of errors can be + handled similary to other SCSI errors. Note that sense data + may indicate ATA bus error (e.g. Sense Key 04h HARDWARE ERROR + && ASC/ASCQ 47h/00h SCSI PARITY ERROR). In such + cases, the error should be considered as an ATA bus error and + handled according to . + + + + + + ATA device error (NCQ) + + + NCQ command error is indicated by cleared BSY and set ERR bit + during NCQ command phase (one or more NCQ commands + outstanding). Although STATUS and ERROR registers will + contain valid values describing the error, READ LOG EXT is + required to clear the error condition, determine which command + has failed and acquire more information. + + + + READ LOG EXT Log Page 10h reports which tag has failed and + taskfile register values describing the error. With this + information the failed command can be handled as a normal ATA + command error as in and all + other in-flight commands must be retried. Note that this + retry should not be counted - it's likely that commands + retried this way would have completed normally if it were not + for the failed command. + + + + Note that ATA bus errors can be reported as ATA device NCQ + errors. This should be handled as described in . + + + + If READ LOG EXT Log Page 10h fails or reports NQ, we're + thoroughly screwed. This condition should be treated + according to . + + + + + + ATA bus error + + + ATA bus error means that data corruption occurred during + transmission over ATA bus (SATA or PATA). This type of errors + can be indicated by + + + + + + + ICRC or ABRT error as described in . + + + + + + Controller-specific error completion with error information + indicating transmission error. + + + + + + On some controllers, command timeout. In this case, there may + be a mechanism to determine that the timeout is due to + transmission error. + + + + + + Unknown/random errors, timeouts and all sorts of weirdities. + + + + + + + As described above, transmission errors can cause wide variety + of symptoms ranging from device ICRC error to random device + lockup, and, for many cases, there is no way to tell if an + error condition is due to transmission error or not; + therefore, it's necessary to employ some kind of heuristic + when dealing with errors and timeouts. For example, + encountering repetitive ABRT errors for known supported + command is likely to indicate ATA bus error. + + + + Once it's determined that ATA bus errors have possibly + occurred, lowering ATA bus transmission speed is one of + actions which may alleviate the problem. See for more information. + + + + + + PCI bus error + + + Data corruption or other failures during transmission over PCI + (or other system bus). For standard BMDMA, this is indicated + by Error bit in the BMDMA Status register. This type of + errors must be logged as it indicates something is very wrong + with the system. Resetting host controller is recommended. + + + + + + Late completion + + + This occurs when timeout occurs and the timeout handler finds + out that the timed out command has completed successfully or + with error. This is usually caused by lost interrupts. This + type of errors must be logged. Resetting host controller is + recommended. + + + + + + Unknown error (timeout) + + + This is when timeout occurs and the command is still + processing or the host and device are in unknown state. When + this occurs, HSM could be in any valid or invalid state. To + bring the device to known state and make it forget about the + timed out command, resetting is necessary. The timed out + command may be retried. + + + + Timeouts can also be caused by transmission errors. Refer to + for more details. + + + + + + Hotplug and power management exceptions + + + <<TODO: fill here>> + + + + + + + + EH recovery actions + + + This section discusses several important recovery actions. + + + + Clearing error condition + + + Many controllers require its error registers to be cleared by + error handler. Different controllers may have different + requirements. + + + + For SATA, it's strongly recommended to clear at least SError + register during error handling. + + + + + Reset + + + During EH, resetting is necessary in the following cases. + + + + + + + HSM is in unknown or invalid state + + + + + + HBA is in unknown or invalid state + + + + + + EH needs to make HBA/device forget about in-flight commands + + + + + + HBA/device behaves weirdly + + + + + + + Resetting during EH might be a good idea regardless of error + condition to improve EH robustness. Whether to reset both or + either one of HBA and device depends on situation but the + following scheme is recommended. + + + + + + + When it's known that HBA is in ready state but ATA/ATAPI + device in in unknown state, reset only device. + + + + + + If HBA is in unknown state, reset both HBA and device. + + + + + + + HBA resetting is implementation specific. For a controller + complying to taskfile/BMDMA PCI IDE, stopping active DMA + transaction may be sufficient iff BMDMA state is the only HBA + context. But even mostly taskfile/BMDMA PCI IDE complying + controllers may have implementation specific requirements and + mechanism to reset themselves. This must be addressed by + specific drivers. + + + + OTOH, ATA/ATAPI standard describes in detail ways to reset + ATA/ATAPI devices. + + + + + PATA hardware reset + + + This is hardware initiated device reset signalled with + asserted PATA RESET- signal. There is no standard way to + initiate hardware reset from software although some + hardware provides registers that allow driver to directly + tweak the RESET- signal. + + + + + Software reset + + + This is achieved by turning CONTROL SRST bit on for at + least 5us. Both PATA and SATA support it but, in case of + SATA, this may require controller-specific support as the + second Register FIS to clear SRST should be transmitted + while BSY bit is still set. Note that on PATA, this resets + both master and slave devices on a channel. + + + + + EXECUTE DEVICE DIAGNOSTIC command + + + Although ATA/ATAPI standard doesn't describe exactly, EDD + implies some level of resetting, possibly similar level + with software reset. Host-side EDD protocol can be handled + with normal command processing and most SATA controllers + should be able to handle EDD's just like other commands. + As in software reset, EDD affects both devices on a PATA + bus. + + + Although EDD does reset devices, this doesn't suit error + handling as EDD cannot be issued while BSY is set and it's + unclear how it will act when device is in unknown/weird + state. + + + + + ATAPI DEVICE RESET command + + + This is very similar to software reset except that reset + can be restricted to the selected device without affecting + the other device sharing the cable. + + + + + SATA phy reset + + + This is the preferred way of resetting a SATA device. In + effect, it's identical to PATA hardware reset. Note that + this can be done with the standard SCR Control register. + As such, it's usually easier to implement than software + reset. + + + + + + + + One more thing to consider when resetting devices is that + resetting clears certain configuration parameters and they + need to be set to their previous or newly adjusted values + after reset. + + + + Parameters affected are. + + + + + + + CHS set up with INITIALIZE DEVICE PARAMETERS (seldomly used) + + + + + + Parameters set with SET FEATURES including transfer mode setting + + + + + + Block count set with SET MULTIPLE MODE + + + + + + Other parameters (SET MAX, MEDIA LOCK...) + + + + + + + ATA/ATAPI standard specifies that some parameters must be + maintained across hardware or software reset, but doesn't + strictly specify all of them. Always reconfiguring needed + parameters after reset is required for robustness. Note that + this also applies when resuming from deep sleep (power-off). + + + + Also, ATA/ATAPI standard requires that IDENTIFY DEVICE / + IDENTIFY PACKET DEVICE is issued after any configuration + parameter is updated or a hardware reset and the result used + for further operation. OS driver is required to implement + revalidation mechanism to support this. + + + + + + Reconfigure transport + + + For both PATA and SATA, a lot of corners are cut for cheap + connectors, cables or controllers and it's quite common to see + high transmission error rate. This can be mitigated by + lowering transmission speed. + + + + The following is a possible scheme Jeff Garzik suggested. + + +
+ + If more than $N (3?) transmission errors happen in 15 minutes, + + + + + if SATA, decrease SATA PHY speed. if speed cannot be decreased, + + + + + decrease UDMA xfer speed. if at UDMA0, switch to PIO4, + + + + + decrease PIO xfer speed. if at PIO3, complain, but continue + + + +

It turns out that the problem is one of padding (the firmware cksum engine works only on 32-bit chunks, yuck), so the special casing for length == 1 wasn't sufficient anyway. This patch addresses the issue, as well the other issue of i386 + CONFIG_HIGHMEM being broken. It is pretty much the same workaround that Adaptec themselves used in their Windows driver. I have yet to check if it fixes the problem when the skb is non-linear, but this patch _will_ solve the problem for 99% of the users out there (those not using sendfile).

This ensures fail-over is rapid for multicast traffic as well. Otherwise, multicast traffic will be lost until the next IGMP membership report poll timeout. This is conceptually similar to the treatment of IGMP traffic in bond_alb_xmit.

This fixes a race condition with early start of udev, originally tracked down by Suresh B. Siddha. The problem was that switching to the user space VM would not clear the global low mappings for the beginning of memory, which lead to memory corruption. Drop the global bits. The kernel mapping stays global because it should stay constant.

This also creates merged versions of do_init_bootmem, paging_init and mem_init and moves them to arch/powerpc/mm/mem.c. It gets rid of the mem_pieces stuff. I made memory_limit a parameter to lmb_enforce_memory_limit rather than a global referenced by that function. This will require some small changes to ppc64 if we want to continue building ARCH=ppc64 using the merged lmb.c.

There's code in the CMC handler that's supposed to disable CMC interrupts and switch to polling mode when it sees a bunch of CMCs. Because disabling CMCs across all CPUs isn't safe in interrupt context, the disable is done with a schedule_work(). But with continual CMC interrupts, the schedule_work() never gets executed. The following patch immediately disables CMC interrupts for the current CPU. This then allows (at least) one CPU to ignore CMC interrupts, execute the schedule_work() code, and disable CMC interrupts on the rest of the CPUs.

Using "putname()" without the underscores will leak memory, because the allocation will have been hidden from the AUDITSYSCALL code. Arguably the real bug is that the AUDITSYSCALL code is really broken, but in the meantime this fixes the problem people see. Reported by Robert Derr, patch by Rick Lindsley.

This scenario is not possbile if 'A' does do_group_exit(), because it sets sig->flags = SIGNAL_GROUP_EXIT and delivers SIGKILL to subthreads atomically, holding both tasklist_lock and sighand->lock. That means that do_signal_stop() will notice !SIGNAL_STOP_DEQUEUED after re-locking ->sighand. And it is not possible to any other thread to re-add SIGNAL_STOP_DEQUEUED later, because dequeue_signal() can only return SIGKILL. I think it is better to change do_coredump() to do sigaddset(SIGKILL) and signal_wake_up() under sighand->lock, but this patch is much simpler.

This document explains more fully how that the +requesting algorithm works. + +The process starts by either the kernel requesting a service by calling +request_key(): + + struct key *request_key(const struct key_type *type, + const char *description, + const char *callout_string); + +Or by userspace invoking the request_key system call: + + key_serial_t request_key(const char *type, + const char *description, + const char *callout_info, + key_serial_t dest_keyring); + +The main difference between the two access points is that the in-kernel +interface does not need to link the key to a keyring to prevent it from being +immediately destroyed. The kernel interface returns a pointer directly to the +key, and it's up to the caller to destroy the key. + +The userspace interface links the key to a keyring associated with the process +to prevent the key from going away, and returns the serial number of the key to +the caller. + + +=========== +THE PROCESS +=========== + +A request proceeds in the following manner: + + (1) Process A calls request_key() [the userspace syscall calls the kernel + interface]. + + (2) request_key() searches the process's subscribed keyrings to see if there's + a suitable key there. If there is, it returns the key. If there isn't, and + callout_info is not set, an error is returned. Otherwise the process + proceeds to the next step. + + (3) request_key() sees that A doesn't have the desired key yet, so it creates + two things: + + (a) An uninstantiated key U of requested type and description. + + (b) An authorisation key V that refers to key U and notes that process A + is the context in which key U should be instantiated and secured, and + from which associated key requests may be satisfied. + + (4) request_key() then forks and executes /sbin/request-key with a new session + keyring that contains a link to auth key V. + + (5) /sbin/request-key execs an appropriate program to perform the actual + instantiation. + + (6) The program may want to access another key from A's context (say a + Kerberos TGT key). It just requests the appropriate key, and the keyring + search notes that the session keyring has auth key V in its bottom level. + + This will permit it to then search the keyrings of process A with the + UID, GID, groups and security info of process A as if it was process A, + and come up with key W. + + (7) The program then does what it must to get the data with which to + instantiate key U, using key W as a reference (perhaps it contacts a + Kerberos server using the TGT) and then instantiates key U. + + (8) Upon instantiating key U, auth key V is automatically revoked so that it + may not be used again. + + (9) The program then exits 0 and request_key() deletes key V and returns key + U to the caller. + +This also extends further. If key W (step 5 above) didn't exist, key W would be +created uninstantiated, another auth key (X) would be created [as per step 3] +and another copy of /sbin/request-key spawned [as per step 4]; but the context +specified by auth key X will still be process A, as it was in auth key V. + +This is because process A's keyrings can't simply be attached to +/sbin/request-key at the appropriate places because (a) execve will discard two +of them, and (b) it requires the same UID/GID/Groups all the way through. + + +====================== +NEGATIVE INSTANTIATION +====================== + +Rather than instantiating a key, it is possible for the possessor of an +authorisation key to negatively instantiate a key that's under construction. +This is a short duration placeholder that causes any attempt at re-requesting +the key whilst it exists to fail with error ENOKEY. + +This is provided to prevent excessive repeated spawning of /sbin/request-key +processes for a key that will never be obtainable. + +Should the /sbin/request-key process exit anything other than 0 or die on a +signal, the key under construction will be automatically negatively +instantiated for a short amount of time. + + +==================== +THE SEARCH ALGORITHM +==================== + +A search of any particular keyring proceeds in the following fashion: + + (1) When the key management code searches for a key (keyring_search_aux) it + firstly calls key_permission(SEARCH) on the keyring it's starting with, + if this denies permission, it doesn't search further. + + (2) It considers all the non-keyring keys within that keyring and, if any key + matches the criteria specified, calls key_permission(SEARCH) on it to see + if the key is allowed to be found. If it is, that key is returned; if + not, the search continues, and the error code is retained if of higher + priority than the one currently set. + + (3) It then considers all the keyring-type keys in the keyring it's currently + searching. It calls key_permission(SEARCH) on each keyring, and if this + grants permission, it recurses, executing steps (2) and (3) on that + keyring. + +The process stops immediately a valid key is found with permission granted to +use it. Any error from a previous match attempt is discarded and the key is +returned. + +When search_process_keyrings() is invoked, it performs the following searches +until one succeeds: + + (1) If extant, the process's thread keyring is searched. + + (2) If extant, the process's process keyring is searched. + + (3) The process's session keyring is searched. + + (4) If the process has a request_key() authorisation key in its session + keyring then: + + (a) If extant, the calling process's thread keyring is searched. + + (b) If extant, the calling process's process keyring is searched. + + (c) The calling process's session keyring is searched. + +The moment one succeeds, all pending errors are discarded and the found key is +returned. + +Only if all these fail does the whole thing fail with the highest priority +error. Note that several errors may have come from LSM. + +The error priority is: + + EKEYREVOKED > EKEYEXPIRED > ENOKEY + +EACCES/EPERM are only returned on a direct search of a specific keyring where +the basal keyring does not grant Search permission. diff --git a/Documentation/keys.txt b/Documentation/keys.txt index b22e7c8..4afe03a 100644 --- a/Documentation/keys.txt +++ b/Documentation/keys.txt @@ -361,6 +361,8 @@ The main syscalls are: /sbin/request-key will be invoked in an attempt to obtain a key.

We have separate 32-bit and 64-bit versions of entry.S and misc.S since the code is mostly sufficiently different to be not worth merging. There are some common bits that will be extracted in future.

Revert the offending part. It broke because: a) because this part doesn't fall under the description b) the author didn't know what he was doing here c) the author didn't try to compile the existing code and see that it worked perfectly. d) the author didn't ask us what was happening e) you didn't either, and somebody there should have learned that UML is a bit different. In fact, UML is special in linking to host libc and using its includes. In particular, since host includes always define both __BIG_ENDIAN and __LITTLE_ENDIAN, ntohll() macros started thinking to be in a big-endian world; and on-disk compatibility was broken. Many thanks go to Nix for reporting the problem and correctly diagnosing an endianness problem. Btw, this patch restores the previous code, which worked; but the definitions would be uncorrect if used in kernelspace files. Next patch addresses that.

Wysocki" Date: Sun, 9 Oct 2005 21:19:40 +0200 Subject: [PATCH] x86_64: Set up safe page tables during resume The following patch makes swsusp avoid the possible temporary corruption of page translation tables during resume on x86-64. This is achieved by creating a copy of the relevant page tables that will not be modified by swsusp and can be safely used by it on resume. The problem is that during resume on x86-64 swsusp may temporarily corrupt the page tables used for the direct mapping of RAM. If that happens, a page fault occurs and cannot be handled properly, which leads to the solid hang of the affected system. This leads to the loss of the system's state from before suspend and may result in the loss of data or the corruption of filesystems, so it is a serious issue. Also, it appears to happen quite often (for me, as often as 50% of the time). The problem is related to the fact that (at least) one of the PMD entries used in the direct memory mapping (starting at PAGE_OFFSET) points to a page table the physical address of which is much greater than the physical address of the PMD entry itself. Moreover, unfortunately, the physical address of the page table before suspend (i.e. the one stored in the suspend image) happens to be different to the physical address of the corresponding page table used during resume (i.e. the one that is valid right before swsusp_arch_resume() in arch/x86_64/kernel/suspend_asm.S is executed). Thus while the image is restored, the "offending" PMD entry gets overwritten, so it does not point to the right physical address any more (i.e. there's no page table at the address pointed to by it, because it points to the address the page table has been at during suspend). Consequently, if the PMD entry is used later on, and it _is_ used in the process of copying the image pages, a page fault occurs, but it cannot be handled in the normal way and the system hangs. In principle we can call create_resume_mapping() from swsusp_arch_resume() (ie. from suspend_asm.S), but then the memory allocations in create_resume_mapping(), resume_pud_mapping(), and resume_pmd_mapping() must be made carefully so that we use _only_ NosaveFree pages in them (the other pages are overwritten by the loop in swsusp_arch_resume()). Additionally, we are in atomic context at that time, so we cannot use GFP_KERNEL. Moreover, if one of the allocations fails, we should free all of the allocated pages, so we need to trace them somehow. All of this is done in the appended patch, except that the functions populating the page tables are located in arch/x86_64/kernel/suspend.c rather than in init.c. It may be done in a more elegan way in the future, with the help of some swsusp patches that are in the works now. [AK: move some externs into headers, renamed a function] Signed-off-by: Rafael J.

It may "forget" to service one in some circumstances, including when one of the drive is suspended (it will eventually fail to service the slave when the master is suspended for example). This prevents the wakeup requests that gets queued on wakeup from sleep from beeing serviced in some cases when 2 drives are sharing an IDE bus. The problem is deep enough in the way this code works (and there are probably a few other problematic but rare corner cases) and fixing it would require some major rethinking of the way IDE decides which channel to service. This is not 2.6.14 material. However, in the meantime, Bart has accepted this simple workaround that will fix the crash on wakeup from sleep since this specific corner case is actually hitting users to get into 2.6.14.

Miller" Date: Mon, 10 Oct 2005 16:12:13 -0700 Subject: [SPARC64]: Fix Ultra5, Ultra60, et al. boot failures. On the boot processor, we need to do the move onto the Linux trap table a little bit differently else we'll take unhandlable faults in the firmware address space. Previously we would do the following: 1) Disable PSTATE_IE in %pstate. 2) Set %tba by hand to sparc64_ttable_tl0 3) Initialize alternate, mmu, and interrupt global trap registers. 4) Call prom_set_traptable() That doesn't work very well actually with the way we boot the kernel VM these days. It worked by luck on many systems because the firmware accesses for the prom_set_traptable() call happened to be loaded into the TLB already, something we cannot assume. So the new scheme is this: 1) Clear PSTATE_IE in %pstate and set %pil to 15 2) Call prom_set_traptable() 3) Initialize alternate, mmu, and interrupt global trap registers. and this works quite well. This sequence has been moved into a callable function in assembler named setup-trap_table(). The idea is that eventually trampoline.S can use this code as well. That isn't possible currently due to some complications, but eventually we should be able to do it. Thanks to Meelis Roos for the Ultra5 boot failure report. Signed-off-by: David S.

This is because the urb saves a pointer to "current" when it is posted to the device, but there's no guarantee that this pointer is still valid afterwards. In fact, there are three separate issues: 1) the pointer to "current" can become invalid, since the task could be completely gone when the URB completion comes back from the device. 2) Even if the saved task pointer is still pointing to a valid task_struct, task_struct->sighand could have gone meanwhile. 3) Even if the process is perfectly fine, permissions may have changed, and we can no longer send it a signal. So what we do instead, is to save the PID and uid's of the process, and introduce a new kill_proc_info_as_uid() function.

This means that the inner MTU is smaller than it needs be. Worse yet, given an input MTU which is a multiple of 4 it will always produce an estimate which is not a multiple of 4. For example, given a standard ESP/3DES/MD5 transform and an MTU of 1500, the resulting MTU for transport mode is 1462 when it should be 1464. The reason for this is because IP header lengths are always a multiple of 4 for IPv4 and 8 for IPv6. * Ensure that the block size is at least 4. This is required by RFC2406 and corresponds to what the esp_output function does. At the moment this only affects crypto_null as its block size is 1. Signed-off-by: Herbert Xu Signed-off-by: David S.

A lot of the changes are just adding #include to files that use ppc_md or smp_ops_t. This also arranges for us to use semaphore.c, vecemu.c, vector.S and fpu.S from arch/powerpc/kernel when compiling with ARCH=ppc.

This adds in efficiency as every packet update makes the /sys/class/firmware/dell_rbu/loading and data files to disappear and reappear again. Thus the user app needs to wait for the files to reappear to dump another packet. This slows down the packet update tremendously in case of large number of packets. I am submitting a new patch for dell_rbu which will change the way we do packet updates; In the new method the user app will create a new single file which has already packetized the rbu image and all the packets are now staged in this file. This driver also creates a new entry in /sys/devices/platform/dell_rbu/packet_size ; the user needs to echo the packet size here before downloading the packet file. The user should do the following: create one single file which has all the packets stacked together. echo the packet size in to /sys/devices/platform/dell_rbu/packet_size. echo 1 > /sys/class/firmware/dell_rbu/loading cat the packetfile > /sys/class/firmware/dell_rbu/data echo 0 > /sys/class/firmware/dell_rbu/loading The driver takes the file which came through /sys/class/firmware/dell_rbu/data and takes chunks of paket_size data from it and place in contiguous memory. This makes packet update process very efficient and fast. As all the packet update happens in one single operation. The user can still read back the downloaded file from /sys/devices/platform/dell_rbu/data.

It may also fail with other non-canonical acls -- I can't tell, because that case never triggers: We only send non-canonical acls when we fake up an ACL_MASK entry. Instead of adding fake ACL_MASK entries at the end, inserting them in the correct position makes Solaris+VxFS happy. The Linux client and server sides don't care about entry order. The three-entry-acl special case in which we need a fake ACL_MASK entry was handled in xdr_nfsace_encode. The patch moves this into nfsacl_encode.

The incorrect calculations can result in either an oops or a panic when running fsck depending on the size of the partition. The problem with the seg_size calculation is that it can result in a negative number if size is offset > size. The problem with the nr_segs caculation is returns the wrong number of segments, e.g. it returns 1 when size is 200 and offset is 4095, when it should return 2 or more.

I have fixes for these, but am not comfortable putting them into 2.6.14 at this late date. So, this patch reverts the use of host AIO. I will resubmit the original patch, plus fixes to the driver after 2.6.14 in order to get a reasonable amount of testing before they're exposed to the general public.

It worked, but probably drifted a bit more than could be explained by the actual bad precision of the timebase calibration. We discovered that recently when somebody figured out that the common code was using CLOCK_TICK_RATE to correct the timekeeing, and ppc32 had a completely bogus value for it. This patch turns it into something saner. Probably not as good as doing something based on the actual timebase frequency precision but I'll leave that sort of math to others. This at least makes it better for the common HZ values.

However, some (rare & old) CPUs do not have such timebase and it is a bit annoying to have your stuff just crash because you are running on the wrong CPU... This exposes to userland a CPU feature bit that tells that the current processor doesn't have a standard timebase. It's negative logic so that glibc will still "just work" on older kernels (it will just be unhappy on those old CPUs but that doesn't really matter as distro tend to update glibc & kernel at the same time).

Nevertheless, the code to work around the ARM710 swi bug is itself currently buggy since it uses r8 as a pointer to S_PC while in fact it holds the spsr content these days. Fix that, and simplify the code as well.

Miller" Date: Wed, 12 Oct 2005 12:22:46 -0700 Subject: [SPARC64]: Fix boot failures on SunBlade-150 The sequence to move over to the Linux trap tables from the firmware ones needs to be more air tight. It turns out that to be %100 safe we do need to be able to translate OBP mappings in our TLB miss handlers early. In order not to eat up a lot of kernel image memory with static page tables, just use the translations array in the OBP TLB miss handlers. That solves the bulk of the problem. Furthermore, to make sure the OBP TLB miss path will work even before the fixed MMU globals are loaded, explicitly load %g1 to TLB_SFSR at the beginning of the i-TLB and d-TLB miss handlers. To ease the OBP TLB miss walking of the prom_trans[] array, we sort it then delete all of the non-OBP entries in there (for example, there are entries for the kernel image itself which we're not interested in at all). We also save about 32K of kernel image size with this change. Not a bad side effect :-) There are still some reasons why trampoline.S can't use the setup_trap_table() yet. The most noteworthy are: 1) OBP boots secondary processors with non-bias'd stack for some reason. This is easily fixed by using a small bootup stack in the kernel image explicitly for this purpose. 2) Doing a firmware call via the normal C call prom_set_trap_table() goes through the whole OBP enter/exit sequence that saves and restores OBP and Linux kernel state in the MMUs. This path unfortunately does a "flush %g6" while loading up the OBP locked TLB entries for the firmware call. If we setup the %g6 in the trampoline.S code properly, that is in the PAGE_OFFSET linear mapping, but we're not on the kernel trap table yet so those addresses won't translate properly. One idea is to do a by-hand firmware call like we do in the early bootup code and elsewhere here in trampoline.S But this fails as well, as aparently the secondary processors are not booted with OBP's special locked TLB entries loaded. These are necessary for the firwmare to processes TLB misses correctly up until the point where we take over the trap table. This does need to be resolved at some point. Signed-off-by: David S.

At that point, no more bridge traffic will come in, and the other code will not think that network device is part of a bridge. This should also fix the XEN test problems.

For now, just do nothing to quiet the other cpus, as the system should be quiescent enough. Later we may decide to implement smp_send_stop() like the other SMP platforms do. Based upon a report from Christopher Zimmermann. Signed-off-by: David S.

As an inline helper it will be tokenized before we get to that define and that's it; no matter what we define later, it won't affect anything.

This removes the btext initialization calls from prom_init() and initializes it instead after the device tree is unflattened. It would be nice to do it earlier, but that needs some more infrastructure to find the properties we need in the flattened device tree.

For example, #define list_for_each_rcu(pos, head) \ for (pos = (head)->next; prefetch(pos->next), pos != (head); \ pos = rcu_dereference(pos->next)) It will go something like: pos = (head)->next prefetch(pos->next) pos != (head) do stuff We're missing a barrier here. pos = rcu_dereference(pos->next) fetch pos->next barrier given by rcu_dereference(pos->next) store pos Without the missing barrier, the pos->next value may turn out to be stale. In fact, if "do stuff" were also dereferencing pos and relying on list_for_each_rcu to provide the barrier then it may also break.

I didn't know about messy programs like svgatextmode... Couldn't this be integrated in some linux/drivers/video/console/svgacon.c ?... So because of the existence of the svgatextmode program, the kernel is not supposed to touch to CRT_OVERFLOW/SYNC_END/DISP/DISP_END/OFFSET ? Disabling the check in vgacon_resize() might help indeed, but I'm really not sure whether it will work for any chipset: in my patch, CRT registers are set at each console switch, since stty rows/cols apply to consoles separately... The attached solution is to keep the test, but if it fails, we assume that the caller knows what it does (i.e. it is svgatextmode) and then disable any further call to vgacon_doresize. Svgatextmode is usually used to _expand_ the display, not to shrink it. And it is harmless in the case of a too big stty rows/cols: the display will just be cropped. I tested it on my laptop, and it works fine with svgatextmode. A better solution would be that svgatextmode explicitely tells the kernel not to care about video timing, but for this an interface needs be defined and svgatextmode be patched.

What happened? Highspeed HID devices are correctly recognized and enumerated by the kernel. But even if usbhid kernel module is loaded, no HID reports are received by the kernel. The output of the hardware USB analyzer told me that the host doesn't even poll for interrupt IN transfers (even the "interrupt in" USB transfer are polled by the host). After some debugging in hid-core.c I've found the reason. In case of a highspeed device, the endpoint interval is re-calculated in driver/usb/input/hid-core.c: line 1669: /* handle potential highspeed HID correctly */ interval = endpoint->bInterval; if (dev->speed == USB_SPEED_HIGH) interval = 1 << (interval - 1); Basically this calculation is correct (refer to USB 2.0 spec, 9.6.6). This new calculated value of "interval" is used as input for usb_fill_int_urb: line 1685: usb_fill_int_urb(hid->urbin, dev, pipe, hid->inbuf, 0, hid_irq_in, hid, interval); Unfortunately the same calculation as above is done a second time in usb_fill_int_urb in the file include/linux/usb.h: line 933: if (dev->speed == USB_SPEED_HIGH) urb->interval = 1 << (interval - 1); else urb->interval = interval; This means, that if the endpoint descriptor (of a high speed device) specifies e.g. bInterval = 7, the urb->interval gets the value: hid-core.c: interval = 1 << (7-1) = 0x40 = 64 urb->interval = 1 << (interval -1) = 1 << (63) = integer overflow Because of this the value of urb->interval is sometimes negative and is rejected in core/urb.c: line 353: /* too small? */ if (urb->interval <= 0) return -EINVAL; The conclusion is, that the recalculaton of the interval (which is necessary for highspeed) should not be made twice, because this is simply wrong. ;-) Re-calculation in usb_fill_int_urb makes more sense, because it is the most general approach. So it would make sense to remove it from hid-core.c. Because in hid-core.c the interval variable is only used for calling usb_fill_int_urb, it is no problem to remove the highspeed re-calculation in this file.

In the process of doing so it tried to sleep waiting for KIF_LOCKED while holding the ctx_lock spinlock. Recent fixes have ensured that multiple concurrent retries won't be attempted for a given iocb. Cancel has other problems and has no significant in-tree users that have been complaining about it. So for the immediate future we'll revert sleeping with the lock held and will address proper cancellation and retry serialization in the future.

When the machine has been idle for some time and the driver attempts to powerdown the display, rather than the display going blank, it goes gray with several strange lines. When I hit the "shift" key or other-wise wake up the display, the old video state is not fully restored..." vesafb recently added a blank method which has only 2 states, powerup and powerdown. The powerdown state is used for all blanking levels, but in his case, powerdown does not work correctly for higher levels of display powersaving. Thus, for intermediate power levels, use software blanking, and use only hardware blanking for an explicit powerdown.

After running offline diagnostics, adapter would report corrupted packets on receive. This was because of adapter not being brought out of "RLDRAM test mode". 2. Current EEPROM test works only for Xframe I. Since Xframe II uses different interface(SPI), support for this interface has been added. Also, since SPI supports write access to all areas of EEPROM, negative testing is done only for Xframe I. 3. Return values from subfunctions of offline diagnostics have been corrected. 4. In register test, expected value from rx_queue_cfg register is made to depend on adapter type. 5. After the test, need to restore values at EEPROM offsets 0x4F0 and 0x7F0. These locations were modified as part of test. 6. Use macro SPECIAL_REG_WRITE for write access to mc_rldram_test_ctrl register. Also, couple of unnecessary writes to mc_rldram_test_ctrl have been removed.

From Suzanne Wood : Clarify RCU implementation in bpqether.c. Because bpq_new_device() calls list_add_rcu() and bpq_free_device() calls list_del_rcu(), substitute list_for_each_entry_rcu() for list_for_each_entry() in bpq_get_ax25_dev() and in bpq_seq_start(). Add rcu dereference protection in bpq_seq_next(). The rcu_read_lock()/unlock() in bpq_device_event() are removed because netdev event handlers are called with RTNL locking in place. FYI: bpq_free_device() calls list_del_rcu() which, per list.h, requires synchronize_rcu() which can block or call_rcu() or call_rcu_bh() which cannot block. Herbert Xu notes that synchronization is done here by unregister_netdevice(). This calls synchronize_net() which in turn uses synchronize_rcu().

Currently the NFS client code enforces this ordering locally using semaphores to restrict access to structures until the RPC call is done. This, of course, only works with synchronous RPC calls, since the user process must first grab the semaphore. By dropping semaphores, and instead teaching the RPC engine to hold the RPC calls until they are ready to be sent, we can extend this process to work nicely with asynchronous RPC calls too. This patch adds a new list called "rpc_sequence" that defines the order of the RPC calls to be sent. We add one such list for each state_owner. When an RPC call is ready to be sent, it checks if it is top of the rpc_sequence list. If so, it proceeds. If not, it goes back to sleep, and loops until it hits top of the list. Once the RPC call has completed, it can then bump the sequence id counter, and remove itself from the rpc_sequence list, and then wake up the next sleeper. Note that the state_owner sequence ids and lock_owner sequence ids are all indexed to the same rpc_sequence list, so OPEN, LOCK,... requests are all ordered w.r.t. each other.

This patch ensures that we recheck the file state once nfs_wait_on_sequence() has completed waiting.

The function is called from the via-rhine versions of mdio_read and mdio_write. Those functions are indirectly called from rhine_check_media and rhine_tx_timeout, both of which can be called in interrupt context. So, create tx_timeout_task and check_media_task as instances of struct work_struct inside of rhine_private. Then, change rhine_tx_timeout to invoke schedule_work for tx_timeout_task (i.e. rhine_tx_timeout_task), moving the work to process context. Also, change rhine_error (invoked from rhine_interrupt) to invoke schedule_work for check_media_task (i.e. rhine_check_media_task), which simply calls rhine_check media in process context. Finally, add a call to flush_scheduled_work in rhine_close to avoid any resource conflicts with pending work items. Signed-off-by: John W.

The b44 hardware has a 30-bit DMA mask. On x86, anything less than a 32-bit DMA mask forces allocations into the 16MB GFP_DMA range. The memory there is somewhat limited, often resulting in an inability to initialize the b44 driver. This hack uses streaming DMA allocation APIs in order to provide an alternative in case the GFP_DMA allocation fails. It is somewhat ugly, but not much worse than the similar existing hacks to support SKB allocations in the same driver. FWIW, I have received positive feedback on this from several Fedora users.

At the time of mmap of hugepages, we populate the new PTEs. It is possible that HW has already cached some of the unused PTEs internally. These stale entries never get a chance to be purged in existing control flow. This patch extends the check in page fault code for hugepages. Check if a faulted address falls with in size for the hugetlb file backing it. We return VM_FAULT_MINOR for these cases (assuming that the arch specific page-faulting code purges the stale entry for the archs that need it).

If there is a running timer tracking a different process's CPU time clock when the process owning the timer exits, we deadlock on tasklist_lock in posix_cpu_timer_del via exit_itimers. That code was using tasklist_lock to check for a race with __exit_signal being called on the timer-target task and clearing its ->signal. However, there is actually no such race. __exit_signal will have called posix_cpu_timers_exit and posix_cpu_timers_exit_group before it does that. Those will clear those k_itimer's association with the dying task, so posix_cpu_timer_del will return early and never reach the code in question. In addition, posix_cpu_timer_del called from exit_itimers during execve or directly from timer_delete in the process owning the timer can race with an exiting timer-target task to cause a double put on timer-target task struct. Make sure we always access cpu_timers lists with sighand lock held.

This would only happen when resync/recovery is happening. This patch fixes three vaguely related bugs. 1/ The recent change to use kthreads got the setting of the process name wrong. This fixes it. 2/ The recent change to use kthreads lost the ability for md threads to be signalled with SIG_KILL. This restores that. 3/ There is a long standing bug in that if: - An array needs recovery (onto a hot-spare) and - The recovery is being blocked because some other array being recovered shares a physical device and - The recovery thread is killed with SIG_KILL Then the recovery will appear to have completed with no IO being done, which can cause data corruption. This patch makes sure that incomplete recovery will be treated as incomplete. Note that any kernel affected by bug 2 will not suffer the problem of bug 3, as the signal can never be delivered. Thus the current 2.6.14-rc kernels are not susceptible to data corruption. Note also that if arrays are shutdown (with "mdadm -S" or "raidstop") then the problem doesn't occur. It only happens if a SIGKILL is independently delivered as done by 'init' when shutting down.

This patch (as585) removes the flag from the child. This problem is starting to show up more and more as drivers turn to the kthread API instead of using kernel_thread(). As a result, their kernel threads are now children of the kthread worker instead of modprobe, and they inherit the PF_NOFREEZE flag.

We also introduce alloc_bootmem_low_pages_limit, alloc_bootmem_node_limit, alloc_bootmem_low_pages_node_limit apis, but alloc_bootmem_low_pages_limit is the only api used for swiotlb. The existing alloc_bootmem_low_pages() api could instead have been changed and made to pass right limit to the core allocator. But that would make the patch more intrusive for 2.6.14, as other arches use alloc_bootmem_low_pages(). We may be done that post 2.6.14 as a cleanup. With this, swiotlb gets memory within 4G for both x86_64 and ia64 arches.

As a side effect, it removes use of the term "perfmon" from ppc32, thus avoiding confusion with the unrelated performance counter interface from HP Labs also called "perfmon".

I found a double-free on an skb that could explain this though. dccp_sendmsg and dccp_write_xmit are a little confused as to what should free the packet when something goes wrong.

They were pretty similar already, the chief changes are: - Instead of inline asm to implement current_thread_info(), which needs to be different for ppc32 and ppc64, we use C with an asm("r1") register variable. gcc turns it into the same asm as we used to have for both platforms. - We replace ppc32's 'local_flags' with the ppc64 'syscall_noerror' field. The noerror flag was in fact the only thing in the local_flags field anyway, so the ppc64 approach is simpler, and means we only need a load-immediate/store instead of load/mask/store when clearing the flag. - In readiness for 64k pages, when THREAD_SIZE will be less than a page, ppc64 used kmalloc() rather than get_free_pages() to allocate the kernel stack. With this patch we do the same for ppc32, since there's no strong reason not to. - For ppc64, we no longer export THREAD_SHIFT and THREAD_SIZE via asm-offsets, thread_info.h can now be safely included in asm, as on ppc32. Built and booted on G4 Powerbook (ARCH=ppc and ARCH=powerpc) and Power5 (ARCH=ppc64 and ARCH=powerpc).

The code calls __hash_page() passing it an "access" parameter (the type of access that triggers the hash) containing the bits _PAGE_RW and _PAGE_USER of the linux PTE. The latter is useless in this case and the former is wrong. In fact, if we have a writeable PTE and we pass _PAGE_RW to hash_page(), it will set _PAGE_DIRTY (since we track dirty that way, by hash faulting !dirty) which is not what we want. In fact, the correct fix is to always pass 0. That means that only read-only or already dirty read write PTEs will be preloaded. The (hopefully rare) case of a non dirty read write PTE can't be preloaded this way, it will have to fault in hash_page on the actual access.

Both requests happen, but the southbridge hardware only acknowledges the C-state change. The PowerNow! driver is then stuck in a loop, waiting for the P-state change acknowledgement. The driver eventually times out, but can no longer perform P-state changes. It turns out the solution is to resend the P-state change, which the southbridge will acknowledge normally. Thanks to Johannes Winkelmann for reporting this and testing the fix.

Since then we've gotten the signal_struct.live counter, and do_exit can reliably do group-wide cleanup work. This patch moves the call to do_exit, where it's made without locks.

Thanks to Joel Soete for pointing out this oversight. Signed-off-by: Grant Grundler 2.6.14-rc2-pa3 move "sync" outside the main loop that fills IO Pdir. Signed-off-by: Grant Grundler remove explicit use of sr0 in fdc ops. Thanks to Joel Soete for reminding me were I added those... Signed-off-by: Grant Grundler 2.6.14-rc2-pa2 - make SBA more anal about invalidating pdir entries Previous code cleared the valid flag a pdir entry but it did NOT guarantee this change was visible to the PDIR before writing the PCOM register. Ie the SBA could pick up a stale entry if the write happened to hit the SBA before the cacheline was flushed from the cache. Long term, I think I want to make this a compile time flag. Developement tree should enable anal pdir checking by default and Debian can disable it with either a CONFIG option or one-line patch. fdc/sync options can only negatively affect performance though I haven't measure how much yet. If someone can run netperf TCP_RR across gige and compare -pa1 and -pa2, that would be sufficient. Cleaned up the use of "fdc" to make sure it's using "kernel" space id (specify sr0 but maps to sr4-7). It seems a bit fragile to assume "sr1" gets loaded with KERNEL_SPACE which is how the code works today. Tested on 32 and 64-bit SMP kernels on j6k. Signed-off-by: Grant Grundler remove PDC_NARROW from SBA and document history of PDC_NARROW a bit. It will still show up in an older kernel's .config file. Signed-off-by: Grant Grundler if/ifdef cleanups from Joel Soete. Signed-off-by: Grant Grundler 2.6.12-rc4-pa2 fix 32-bit support for Astro platforms o Since my last SBA code change, SBA could allocate more than 1GB of IOVA space on Astro boxes with more than 1GB of RAM when running 32-bit kernel. This is bad since IOMMU can only talk to the first 1GB at most. Kudos to jejb for quickly spotting that bug. o jejb also noted SBA should *always* reject DMA masks > 32-bits since DMA-mapping.txt indicates caller should try again with 32-bits. o off-by-one error when comparing the mask to IOVA space size.

Thanks to Joel Soete for pointing out this oversight. Signed-off-by: Grant Grundler 2.6.14-rc2-pa3 fdc/lci should be %r0 instead 0 for index (PA 1.1 compliance) From: Joel Soete Signed-off-by: Grant Grundler Explain why we need insert_resource() instead of request_resource(). Fundementally, this is more convoluted for ccio driver because of o legacy (HP-PB) transperant bridges. o support for MMIO behind card-mode Dino (PCI) o support for above bridges without ccio in the box SBA driver doesn't have to worry about those issues. Signed-off-by: Grant Grundler Use insert_resource instead of request_resource now that the subdevices will already have their resources claimed Signed-off-by: Matthew Wilcox re-enable use of "inline" for perf critical functions. Signed-off-by: Grant Grundler 2.6.12-rc4-pa5 fix sign extension of MMIO range Fixes the problem of claiming a range that is disabled on 64-bit kernel: ccio_init_resource() claimed CCIO bus address space (ffffffff00000000, ffffffffffffffff) also removes use of __FILE__.

Kudos to jejb for pointing out the the possibility that ext2_test_bit and ext2_find_next_zero() may in fact not be enumerating bits in the bitmap because of endianess.

I think header files that might go to user space should use something userspace will know about (__LP64__).

The problem has been around since 2.6.9-rc2-pa6 when we allowed floating point registers to be used in kernel code. The essence of the problem is that gcc prefers to use floating point for integer divides and multiples. Further, it can rely on the values in the no clobber fp regs being correct across a function call. Unfortunately, our task switch function only saves the integer no clobber registers, not the fp ones, so if gcc makes a function call to any function in the kernel which could sleep, the values it is relying on in any no clobber floating point register may be lost. In the case of alloc_slabmgmt, the value of the page offset is being stored in %fr12 across a call to kmem_getpages(), which sleeps if no pages are available. Thus, the offset can be trashed and the slab code can end up with a completely bogus address leading to corruption. Kudos to Randolph who came up with the program to trip this problem at will and thus allowed it to be tracked and fixed.

If we don't, then there's a window where we miss an EQ entry and then get stuck because we don't get another EQ event.

This doesn't work because the timer may have already fired when we acquire the write lock in neigh_changeaddr. The result is that the timer may keep firing for quite a while until the entry reaches NEIGH_FAILED. It should be setting the nud_state straight away so that if the timer has already fired it can simply exit once we relinquish the lock. In fact, this whole function is simply duplicating the logic in neigh_ifdown which in turn is already doing the right thing when it comes to deleting timers and setting nud_state. So all we have to do is take that code out and put it into a common function and make both neigh_changeaddr and neigh_ifdown call it.

There's no way to destroy this cache, so when we discard an overall idr tree we end up leaking some memory. Add and use idr_destroy() for this. v9fs and infiniband also need to use idr_destroy() to avoid leaks. Or, we make the cache global, like radix_tree_preload(). Which is probably better. Later.

This causes problems on non-cache-coherent architectures, because the device doing DMA won't see updates to the payload buffers that exist only in the CPU cache. Fix this by having all MAD consumers use ib_create_send_mad() to allocate their send buffers, and moving the DMA mapping into the MAD layer so it can be done just before calling send (and after any modifications of the send buffer by the MAD layer). Tested on a non-cache-coherent PowerPC 440SPe system.

As this dereference directly follows a list_for_each_entry_rcu line, we have already taken a read barrier with respect to getting an entry from the list. This read barrier guarantees that all values read out of fa are valid. In particular, the contents of structure pointed to by fa->fa_info is initialised before fa->fa_info is actually set (see fn_trie_insert); the setting of fa->fa_info itself is further separated with a write barrier from the insertion of fa into the list.

This also defines a CONFIG_PPC_I8259 symbol to select i8259.o for inclusion, and makes the platforms that need it select that symbol.

The parts of rtas.c that are to do with pSeries-specific error logging are protected by a new CONFIG_RTAS_ERROR_LOGGING symbol. The inclusion of rtas.o is controlled by the CONFIG_PPC_RTAS symbol, and the relevant platforms select that.

It also has no device_type on the /memory node and blows up if the output buffer for package-to-path is too big. This also fixes a bug with calling alloc_up with align == 0, where we did _ALIGN_UP(alloc_bottom, 0) which will end up as 0. Lastly, we now check the return value (in r3) from calling the prom, and return -1 from call_prom if we get a negative value back.

According to the HFS+ documentation these are files which are unlinked while in use. However, there may be a bug in the Linux hfsplus implementation which causes this to happen even when the files are not in use. It looks like the "opencnt" field is never initialized as (I think) it should be in hfsplus_read_inode. This means that a file can appear to be still in use when in fact it has been closed.

FP registers could be corrupted, leading to strange random application crashes. The confusion arises, because the thread_struct has (and requires) a 64-bit area to save the fpscr, because we use load/store double instructions to get it in to/out of the FPU. However, only the low 32-bits are actually used, so we want to treat it as a 32-bit quantity when manipulating its bits to avoid extra load/stores on 32-bit. This patch replaces the current definition with a structure of two 32-bit quantities (pad and val), to clarify things as much as is possible. The 'val' field is used when manipulating bits, the structure itself is used when obtaining the address for loading/unloading the value from the FPU. While we're at it, consolidate the 4 (!) almost identical versions of cvt_fd() and cvt_df() (arch/ppc/kernel/misc.S, arch/ppc64/kernel/misc.S, arch/powerpc/kernel/misc_32.S, arch/powerpc/kernel/misc_64.S) into a single version in fpu.S. The new version takes a pointer to thread_struct and applies the correct offset itself, rather than a pointer to the fpscr field itself, again to avoid confusion as to which is the correct field to use. Finally, this patch makes ARCH=ppc64 also use the consolidated fpu.S code, which it previously did not. Built for G5 (ARCH=ppc64 and ARCH=powerpc), 32-bit powermac (ARCH=ppc and ARCH=powerpc) and Walnut (ARCH=ppc, CONFIG_MATH_EMULATION=y). Booted on G5 (ARCH=powerpc) and things which previously fell over no longer do.

Likewise, we've never needed it for ppc64, but we still had an include/asm-ppc64/bootinfo.h from which nothing was used. This patch removes that file, and all references to it in arch/ppc64 and arch/powerpc. A related, unused variable 'boot_mem_size' is also removed from setup_32.c. The bootinfo stuff remains in ARCH=ppc for the time being. Built and booted on Power5 (ARCH=ppc64 and ARCH=powerpc), built for 32-bit powermac (ARCH=powerpc and ARCH=ppc).

It has usually been blamed on foreign operating systems. However, some of those reports implicate Linux as both systems are running Linux or the TCP connection is going across the loopback interface. In fact, there really is a bug in the Linux TCP header prediction code that's been there since at least 2.1.8. This bug was tracked down with help from Dale Blount. The effect of this bug ranges from harmless "Treason uncloaked" messages to hung/aborted TCP connections. The details of the bug and fix is as follows. When snd_wnd is updated, we only update pred_flags if tcp_fast_path_check succeeds. When it fails (for example, when our rcvbuf is used up), we will leave pred_flags with an out-of-date snd_wnd value. When the out-of-date pred_flags happens to match the next incoming packet we will again hit the fast path and use the current snd_wnd which will be wrong. In the case of the treason messages, it just happens that the snd_wnd cached in pred_flags is zero while tp->snd_wnd is non-zero. Therefore when a zero-window packet comes in we incorrectly conclude that the window is non-zero. In fact if the peer continues to send us zero-window pure ACKs we will continue making the same mistake. It's only when the peer transmits a zero-window packet with data attached that we get a chance to snap out of it. This is what triggers the treason message at the next retransmit timeout.

We start a periodic timer which polls the catastrophic error reporting buffer in device memory. If an error is detected, we dump the contents of the buffer for port-mortem debugging, and report a fatal asynchronous error to higher levels. In the future we can try to recover from these errors by resetting the device, but this will require some work in higher-level code as well. Let's get this in now, so that we at least get catastrophic errors reported in logs.

Oddly enough though, specifying the structures as packed the long way - one by one with the packed attribute does work. Rather than fighting over whether this is a gcc bug or some obscure side effect of pragma pack, it is easier to do what most (all but 96 other places in the kernel) do - and replace pragma pack with dozens of attribute(packed) structure qualifiers. Much more verbose ... but at least it works.

When a process enters flush_tlb_range() to purge TLBs for another process, it is possible to avoid flush_tlb_all() and instead allow sn2_global_tlb_purge() to purge TLBs only where necessary. This patch modifies flush_tlb_range() so that this case can be handled by platform TLB purge functions and updates ia64_global_tlb_purge() accordingly. sn2_global_tlb_purge() now calculates the region register value from the mm argument introduced with this patch.

The test can be unnecessarily long (and occurs while holding the tasklist_lock). Especially long on a large system with thousands of active tasks. The ptrace caller (presumably a debugger) specifies the pid of its target and an address to peek or poke. But the debugger could be attached to several tasks. The idea of find_thread_for_addr() is to find whether the target address is in the RBS for any of those tasks. Currently it searches the thread-list of the target pid. If that search does not find a match, and the shared mm-struct's user count indicates that there are other tasks sharing this address space (a rare occurrence), a search is made of all the tasks in the system. Another approach can drastically shorten this procedure. It depends upon the fact that in order to peek or poke from/to any task, the debugger must first attach to that task. And when it does, the attached task is made a child of the debugger (is chained to its children list). Therefore we can search just the debugger's children list.

The lookup cache would be invalid, of course, if the parent directory's mtime had changed, so nfs_lookup performed an inode revalidation on the parent. Since nfs_lookup() doesn't use a cache anymore, the revalidation is no longer necessary. There are cases where it will generate a lot of unnecessary GETATTR traffic. See http://bugzilla.linux-nfs.org/show_bug.cgi?id=9 Test-plan: Use lndir and "rm -rf" and watch for excess GETATTR traffic or application level errors.

This reduces code duplication, eases enforcing semantics over dispatch queue, and simplifies specific ioscheds.

This prevernts AS from doing incorrect update_write_batch after the forced dispatched requests are finished. * In cfq-iosched, cfqd->rq_in_driver currently counts the number of activated (removed) requests to determine whether queue-kicking is needed and cfq_max_depth has been reached. With generic dispatch queue, I think counting the number of dispatched requests would be more appropriate. * cfq_max_depth can be lowered to 1 again. Original from Tejun Heo, modified version applied.

This patch assumes generic dispatch queue patchset is applied. * Each request is tagged with REQ_ELVPRIV flag if it has its elevator private data set. * Requests which doesn't have REQ_ELVPRIV flag set never enter iosched. They are always directly back inserted to dispatch queue. Of course, elevator_put_req_fn is called only for requests which have its REQ_ELVPRIV set. * Request queue maintains the current number of requests which have its elevator data set (elevator_set_req_fn called) in q->rq->elvpriv. * If a request queue has QUEUE_FLAG_BYPASS set, elevator private data is not allocated for new requests. To switch to another iosched, we set QUEUE_FLAG_BYPASS and wait until elvpriv goes to zero; then, we attach the new iosched and clears QUEUE_FLAG_BYPASS. New implementation is much simpler and main code paths are less cluttered, IMHO.

The main difference for ppc64 is that the 'p' command to call show_state (which was always pretty dodgy) has been replaced by the ppc32 'p' command, which calls a given procedure (so in fact the old 'p' command behaviour can be achieved with 'p $show_state').

While there are no platforms in the tree ATM that use it, it has been tested tested on the IXP2350 NPU and I would like to get the support for that chipset upstream one piece at a time. There are also other Intel chipset ports in development that are waiting on this to go upstream. The patch replaces the print formats for physical addresses with %016llx which will create a bit extraneous output on 32-bit systems, but I think that is cleaner than having #ifdefs, specially since users will only see the output in error cases.

I submitted an ALSA patch for this http://thread.gmane.org/gmane.linux.alsa.devel/27804 issue and it was suggested that it might be preferable to change the register definitions to use u32. Most other subarches seem to use u32 for their register type, at least the ones which use a __REG macro (like the PXA) do. Nico indicated in the thread above that he wouldn't mind this patch. Changing the type required fixes for opposite warnings in the pxa2xx usb gadget code but that was the only new warning introduced on defconfig or lubbock, mainstone and our own PXA255 boards.

The latter left with unsigned int __nocast; we might want to add a different type for those but for now let's leave them alone. That, BTW, is a case when __nocast use had been actively confusing - it had been used in the same code for two different and similar types, with no way to catch misuses. Switch of gfp_t to bitwise had caught that immediately... One tricky bit is left alone to be dealt with later - mapping->flags is a mix of gfp_t and error indications. Left alone for now.

Honor power mode parameter of pxa_cpu_suspend(mode), no longer force to 3 (sleep). Full Deep Sleep low-power mode support for PXA27x is pending generic PM interfaces to select more than 2 suspend-to-RAM-style power modes, but this is expected soon. This can be hardcoded in the meantime by replacing the pxa_cpu_suspend() parameter value. From David Burrage and Todd Poynor. Try #2 removes one of the register copies and moves the code to save the pxa_cpu_suspend parameter to immediately surround the call that requires the parameter value be preserved.

ISP23xx and ISP24xx chips have support for an adaptive method of posting SCSI command completions for multiple SCSI commands during a single system interrupt. SCSI commands are placed on the system response queue without interrupting the host until 1) a delay timer expires; or 2) a SCSI command completes with an error. As long as the host software (qla2xxx) services the response queue for completions (this polling is done during queuecommand()) within the 'delay timer' period, the firmware will not generate system interrupt.

The system in question debian stable, using udev to manage /dev. The following patch to ide-tape.c allows udev to create the cdev nodes for my drive.

This will allow us to (hopefully) fix up the input and video class subsystem mess. But please people, don't go crazy and start making huge trees of class devices, you should only need 2 levels deep to get everything to work (remember to use a class_interface to get notification of a new class device being added to the system.) Oh, this also allows us to have the possibility of potentially, someday, moving /sys/block into /sys/class. The main hindrance is that pesky /dev numberspace issue...

The main culprits are due to the initialisation functions not being declared in a header file. Also, the firmware.c file should include to get the prototype of firmware_register() and firmware_unregister(). This patch moves the init function declerations from the init.c file to the base.h, and ensures it is included in all the relevant c sources. It also adds to the included headers for firmware.c. The patch does not solve all the sparse errors generated, but reduces the count significantly. drivers/base/core.c:161:1: warning: symbol 'devices_subsys' was not declared.

Then all devices were called at SUSPEND_SAVE_STATE level, and finally SUSPEND_POWER_DOWN level. However, with PM v2, to maintain compatibility for platform devices, I arranged for the PM v2 suspend/resume callbacks to call the old PM v1 suspend/resume callbacks three times with each level in order so that existing drivers continued to work. Since this is obsolete infrastructure which is no longer necessary, we can remove it. Here's an (untested) patch to do exactly that.

This patch incorporate the review comments by Jeff Garzik. 2. Renamed USO as UFO (UDP Fragmentation Offload) 3. udp sendfile support with UFO This patches uses scatter-gather feature of skb to generate large UDP datagram. Below is a "how-to" on changes required in network device driver to use the UFO interface. UDP Fragmentation Offload (UFO) Interface: ------------------------------------------- UFO is a feature wherein the Linux kernel network stack will offload the IP fragmentation functionality of large UDP datagram to hardware. This will reduce the overhead of stack in fragmenting the large UDP datagram to MTU sized packets 1) Drivers indicate their capability of UFO using dev->features |= NETIF_F_UFO | NETIF_F_HW_CSUM | NETIF_F_SG NETIF_F_HW_CSUM is required for UFO over ipv6. 2) UFO packet will be submitted for transmission using driver xmit routine. UFO packet will have a non-zero value for "skb_shinfo(skb)->ufo_size" skb_shinfo(skb)->ufo_size will indicate the length of data part in each IP fragment going out of the adapter after IP fragmentation by hardware. skb->data will contain MAC/IP/UDP header and skb_shinfo(skb)->frags[] contains the data payload. The skb->ip_summed will be set to CHECKSUM_HW indicating that hardware has to do checksum calculation. Hardware should compute the UDP checksum of complete datagram and also ip header checksum of each fragmented IP packet. For IPV6 the UFO provides the fragment identification-id in skb_shinfo(skb)->ip6_frag_id. The adapter should use this ID for generating IPv6 fragments.

The driver sends the heartbeat every 2 seconds and the ASF firmware will timeout and reset the device if no heartbeat is received after 5 seconds. The old scheme of 2 minutes is ineffective. tg3_write_mem_fast() is added to speed up the IO to send the heartbeat.

The old code mallocs and maps all the buffers in the pools regardless of MTU size and it also limits the number of buffer pools to three. This patch makes the driver malloc and map the buffers necessary to support the current MTU. It also changes the hardcoded names of the buffer pool number, size, and elements to arrays to make it easier to change (with the hope of making them runtime parameters in the future).

This patch is quite big (~234K) because there is virtualy 0% of common code between old and new version. New driver uses NAPI, it solves stability problems under heavy packet load and low memory, corrects chip register access and fixes numerous small bugs I don't even remember now. This patch has been tested on all supported in 2.6 PPC 4xx boards. It's been used in production for almost a year now on custom 4xx hardware. PPC32 specific parts are already upstream. Patch was acked by the current EMAC driver maintainer (Matt Porter). I will be maintaining this new version.

While some other sensors chips respond to all addresses in 0x290-0x297 range, Winbond chips respond to 0x295-0x296 only (this behavior is implied by documentation, and matches behavior observed on real systems). This is not problem alone, as no BIOS was found to put something at these unused addresses, and sensors chip itself provides nothing there as well. But in addition to only respond to these two addresses, also BIOS vendors report in their ACPI-PnP structures that there is some resource at I/O address 0x295 of length 2. And when later this hwmon driver attempts to request region with base 0x290/length 8, it fails as one request_region cannot span more than one device. Due to this we have to ask only for region this hardware really occupies, otherwise driver cannot be loaded on systems with ACPI-PnP enabled.

The key change is that it uses the new __iomem/iowrite8/ioread8 functions to abstract the direct or memory-mapped variants of register access. Also, the original driver would crash on module load on the Alpha because the PCI memory region was not remapped into kernel memory. I have managed the following testing: * compiled and tested it on my Alpha UP2000+ system. * compiles cleanly for x86 but I don't have the hardware to test.

The original implementation was known to have bugs (credits go to Hideki Iwamoto for reporting many of them recently), and was incomplete due to a conceptual limitation. The rewrite affects only software PEC. Hardware PEC needs very little code and is mostly untouched. Technically, both implementations differ in that the original one was emulating PEC in software by modifying the contents of an i2c_smbus_data union (changing the transaction to a different type), while the new one works one level lower, on i2c_msg structures (working on message contents). Due to the definition of the i2c_smbus_data union, not all SMBus transactions could be handled (at least not without changing the definition of this union, which would break user-space compatibility), and those which could had to be implemented individually. At the opposite, adding PEC to an i2c_msg structure can be done on any SMBus transaction with common code. Advantages of the new implementation: * It's about twice as small (from ~136 lines before to ~70 now, only counting i2c-core, including blank and comment lines). The memory used by i2c-core is down by ~640 bytes (~3.5%). * Easier to validate, less tricky code. The code being common to all transactions by design, the risk that a bug can stay uncovered is lower. * All SMBus transactions have PEC support in I2C emulation mode (providing the non-PEC transaction is also implemented). Transactions which have no emulation code right now will get PEC support for free when they finally get implemented. * Allows for code simplifications in header files and bus drivers (patch follows). Drawbacks (I guess there had to be at least one): * PEC emulation for non-PEC capable non-I2C SMBus masters was dropped. It was based on SMBus tricks and doesn't quite fit in the new design. I don't think it's really a problem, as the benefit was certainly not worth the additional complexity, but it's only fair that I at least mention it. Lastly, let's note that the new implementation does slightly affect compatibility (both in kernel and user-space), but doesn't actually break it. Some defines will be dropped, but the code can always be changed in a way that will work with both the old and the new implementations. It shouldn't be a problem as there doesn't seem to be many users of SMBus PEC to date anyway.

Only the ADM1032 chip supports it, and in a rather tricky way, which is why this patch comes with documentation reinforcements. At least, this demonstrates that the new PEC support logic in i2c-core can properly deal with chips with partial PEC support. As enabling PEC causes a significant performance drop, it can be disabled through a sysfs file (unsurprisingly named "pec").

It does +not support PEC on all transactions though, so some care must be taken. + +When reading a register value, the PEC byte is computed and sent by the +ADM1032 chip. However, in the case of a combined transaction (SMBus Read +Byte), the ADM1032 computes the CRC value over only the second half of +the message rather than its entirety, because it thinks the first half +of the message belongs to a different transaction.

Thus, PEC is explicitely disabled +on SMBus Send Byte transactions in the lm90 driver. + +PEC on byte data transactions represents a significant increase in bandwidth +usage (+33% for writes, +25% for reads) in normal conditions.

If the allocation of a new receive skb fails, we now drop the packet we just received and repost the original receive skb. This means that the receive ring always stays full and we don't have to monkey around with trying to schedule a refill task for later.

If, during the time it takes to complete BIST, userspace attempts to access PCI config space, the host bus bridge will master abort the access since the ipr adapter does not respond on the PCI bus for a brief period of time when running BIST. On PPC64 hardware, this master abort results in the host PCI bridge isolating that PCI device from the rest of the system, making the device unusable until Linux is rebooted. This patch is an attempt to close that exposure by introducing some blocking code in the PCI code. When blocked, writes will be humored and reads will return the cached value. Ben Herrenschmidt has also mentioned that he plans to use this in PPC power management.

If, during the time it takes to complete BIST, userspace attempts to access PCI config space, the host bus bridge will master abort the access since the ipr adapter does not respond on the PCI bus for a brief period of time when running BIST. On PPC64 hardware, this master abort results in the host PCI bridge isolating that PCI device from the rest of the system, making the device unusable until Linux is rebooted. This patch makes use of some newly added PCI layer APIs that allow for protection from userspace accessing config space of a device in scenarios such as this.

19:33:38 -0500 Subject: [PATCH] ppc64 PCI Hotplug: cleanup unsymmetric API routines This is a minor patch to the ppc64 PCI hotplug code; it makes the call to rpaphp_unconfig_pci_adapter() symmetric with respect to the call to rpaphp_config_pci_adapter(). I discussed this with John Rose, who had provided the last round of changes for these functions; he appearently had this patch but somehow failed to mail it out. Tested. (added/removed device).

We don't walk the acpi namespace anymore to build a list of bridges and devices. The remaining interaction with ACPI is to run the _OSHP method to transition control of hotplug hardware from system BIOS to the shpc hotplug driver, and to run the _HPP method to get hotplug device parameters like cache line size, latency timer and SERR/PERR enable from BIOS. Note that one of the side effects of this patch is that shpchp does not enable the hot-added device or its DMA bus mastering automatically now. It expects the device driver to do that. This may break some drivers and we will have to fix them as they are reported.

Not all of them will be shpc capable, so look for this capability early in the probe function and return if there's no work to do on this bridge. The old shpc driver did some initialization work on all bridges before detecting that shpc is not supported and unwinds the work it's already done in that case.

There's a lot of overlap in the information kept, and some of it is never used. This patch consolidates the state information to per-slot and eliminates unused data structures. The biggest change is to eliminate the pci_func structure and the code around managing its lists.

The patch adds two PCI fixups to arch/i386/pci/fixup.c, one that happens early on to cache the value of the PCI_CACHE_LINE_SIZE config register, and another that later restores the value, along with a valid IRQ number and some BAR values. I've tested it on my laptop, and it prevents me from running into what I consider to be a major bug: IRQ 11 is disabled by the IRQ debug code, causing my wireless to break. Thanks to Rob for the original patch to ohci1394.c and Stefan for lots of proofreading (and a last minute bug caught in review!) and additional information collection. I think the DMI system list is correct, but we may need to add some more PCI IDs to the PCI_FIXUP macros over time.

Follow-on patches will need to: (a) merge these copies with the originals in the HCD reset methods. they don't wholly agree, despite doing the very same thing; and (b) eventually change it so "usb-handoff" is the default, to help get more robust USB/BIOS/input/... interactions.

It does so by defining some inlined helpers, then using them. - Adds a useful invariant: the only interfaces marked active are those bound to non-suspended drivers. Later patches build on this invariant. - Simplifies the interface driver API (and removes some error paths) by removing the requirement that they record power state changes during suspend and resume callbacks. Now usbcore does that. A few drivers were simplified to address that last change.

When it sees such cases, suspend now just fails cleanly. That logic was not needed during system-wide sleep state transitions; and given the current notions of how to manage selective suspend transitions, we don't want it there either. Where it was particularly handy was coping with various limitations of the sysfs "echo -n N > power/state" support. (These include assuming that "N" is always meaningful to the driver; and that drivers can only transition to state N from state zero.)

The original reason to pass that parameter was so that this routine could suspend any active children. A previous patch removed that functionality ... leaving no reason to pass the parameter. A close analogy is pci_set_power_state, which doesn't need a pm_message_t either. On the internal code path that comes through the driver model, the parameter is now used to distinguish cases where USB devices need to "freeze" but not suspend. It also checks for an error case that's accessible through sysfs: attempting to suspend a device before its interfaces (or for hubs, ports).

It also wraps the calls to those root suspend routines just like on the PCI "USB_SUSPEND not defined" cases, so non-PCI bus glue won't be as tempted to behave very differently. Several of the SOC based OHCI drivers forgot to list those methods; the patch also adds those missing declarations.

(Essential to make OHCI autosuspend behave again...) * HC_SUSPENDED by itself only refers to the root hub's downstream ports. So let HCDs see root hub URBs unless the parent device is suspended. - Remove an assertion we no longer need (and now, also don't want). - Generic suspend/resume updates to work better with swsusp. * Ignore the FREEZE vs SUSPEND distinction for hardware; trying to use it breaks the swsusp snapshots it's supposed to help (sigh). * On resume, mark devices as resumed right away, but then do nothing else if the device is marked NOTATTACHED. These changes shouldn't be very noticable by themselves.

It'll be easier to keep things right from now on. - Now usbcore _always_ calls hcd->hub_suspend as needed, instead of only when USB_SUSPEND is enabled: * Those root hub methods are now called from hub suspend/resume; no more skipping between layers during device suspend/resume; * It now handles cases allowed by sysfs or autosuspended root hubs, by forcing the hub interface to resume too. - All devices, including virtual root hubs, now get the same treatment on their resume paths ... including re-activating all their interfaces. Plus it gets rid of those stub copies of usb_{suspend,resume}_device(), and updates the Kconfig to match the new definition of USB_SUSPEND: it provides (a) selective suspend, downstream from hubs; and (b) remote wakeup, upstream from any device configuration which supports it. This calls for minor followup patches for most HCDs (and their PCI glue).

This patch (as567) formalizes this practice and adds code to usb_bulk_message() for detecting when the target is really an interrupt endpoint. If it is, the routine submits an interrupt URB (using the default interval) instead of a bulk URB. In theory this should help HCDs that don't like it when people try to mix transfer types, queuing both periodic and non-periodic types for the same endpoint. Not fully tested -- I don't have any programs that use USBDEVFS_BULK for interrupt transfers -- but it compiles okay and normal bulk messages work as well as before.

Oddly enough, the identify device command appears to 'fall through' when the devices are in this state, the status register reading exactly the same opcode as the command (0xA1) that was just executed. I think it's safe to label this behaviour as specific to HP8200 devices, I can't get the flash devices to respond like this.

It renames the hub_suspend and hub_resume methods in struct usb_hcd to bus_suspend and bus_resume. These are more descriptive names, since the methods really do suspend or resume an entire USB bus, and less likely to be confused with the hub_suspend and hub_resume routines in hub.c. It also takes David's advice about removing the layer of bus glue, where those methods are called. And it implements a related change that David made to the other HCDs but forgot to put into dummy_hcd.

This patch (as579) improves it in three respects: TDs for a new URB aren't added to the schedule until all of them have been allocated. This way there's no risk of the controller executing some of them when an allocation fails. TDs for an unlinked URB are removed from the schedule as soon as the URB is unlinked, rather than waiting until the URB is given back. This way there's no risk of the controller still executing a TD after the URB completes. The urb->error_count values are now reported correctly. Although since they aren't used in any drivers except for debug messages in the system log, probably nobody cares.

Also made them always show up in the log file. + + (01/25/2000) gkh + Added initial framework for FTDI serial converter so that Bill Ryder + has a place to put his code. + Added the vendor specific info from Handspring. Now we can print out + informational debug messages as well as understand what is happening. + + (01/23/2000) gkh + Fixed problem of crash when trying to open a port that didn't have a + device assigned to it.

This should save lots of memory when + the number of minor nodes goes up to 256. + Added initial support for devices that have more than one port. + Added more debugging comments for the Visor, and added a needed + set_configuration call. + + (01/17/2000) gkh + Fixed the WhiteHEAT firmware (my processing tool had a bug) + and added new debug loader firmware for it. + Removed the put_char function as it isn't really needed. + Added visor startup commands as found by the Win98 dump. + + (01/13/2000) gkh + Fixed the vendor id for the generic driver to the one I meant it to be. + + (01/12/2000) gkh + Forget the version numbering...that's pretty useless... + Made the driver able to be compiled so that the user can select which + converter they want to use. This allows people who only want the Visor + support to not pay the memory size price of the WhiteHEAT. + Fixed bug where the generic driver (idVendor=0000 and idProduct=0000) + grabbed the root hub. Not good. + + version 0.4.0 (01/10/2000) gkh + Added whiteheat.h containing the firmware for the ConnectTech WhiteHEAT + device.

Now everything is based on the - * usb_serial_port structure instead of the larger usb_serial structure. - * This fixes the bug that a multiport device could not have more than - * one port open at one time. - * - * (03/17/2000) gkh - * Added config option for debugging messages. - * Added patch for keyspan pda from Brian Warner. - * - * (03/06/2000) gkh - * Added the keyspan pda code from Brian Warner - * Moved a bunch of the port specific stuff into its own structure. This - * is in anticipation of the true multiport devices (there's a bug if you - * try to access more than one port of any multiport device right now) - * - * (02/21/2000) gkh - * Made it so that any serial devices only have to specify which functions - * they want to overload from the generic function calls (great, - * inheritance in C, in a driver, just what I wanted...) - * Added support for set_termios and ioctl function calls. No drivers take - * advantage of this yet. - * Removed the #ifdef MODULE, now there is no module specific code. - * Cleaned up a few comments in usb-serial.h that were wrong (thanks again - * to Miles Lott). - * Small fix to get_free_serial. - * - * (02/14/2000) gkh - * Removed the Belkin and Peracom functionality from the driver due to - * the lack of support from the vendor, and me not wanting people to - * accidenatly buy the device, expecting it to work with Linux. - * Added read_bulk_callback and write_bulk_callback to the type structure - * for the needs of the FTDI and WhiteHEAT driver. - * Changed all reverences to FTDI to FTDI_SIO at the request of Bill - * Ryder. - * Changed the output urb size back to the max endpoint size to make - * the ftdi_sio driver have it easier, and due to the fact that it didn't - * really increase the speed any. - * - * (02/11/2000) gkh - * Added VISOR_FUNCTION_CONSOLE to the visor startup function. This was a - * patch from Miles Lott (milos@insync.net). - * Fixed bug with not restoring the minor range that a device grabs, if - * the startup function fails (thanks Miles for finding this). - * - * (02/05/2000) gkh - * Added initial framework for the Keyspan PDA serial converter so that - * Brian Warner has a place to put his code. - * Made the ezusb specific functions generic enough that different - * devices can use them (whiteheat and keyspan_pda both need them). - * Split out a whole bunch of structure and other stuff to a separate - * usb-serial.h file. - * Made the Visor connection messages a little more understandable, now - * that Miles Lott (milos@insync.net) has gotten the Generic channel to - * work. Also made them always show up in the log file. - * - * (01/25/2000) gkh - * Added initial framework for FTDI serial converter so that Bill Ryder - * has a place to put his code. - * Added the vendor specific info from Handspring. Now we can print out - * informational debug messages as well as understand what is happening. - * - * (01/23/2000) gkh - * Fixed problem of crash when trying to open a port that didn't have a - * device assigned to it. Made the minor node finding a little smarter, - * now it looks to find a continuous space for the new device. - * - * (01/21/2000) gkh - * Fixed bug in visor_startup with patch from Miles Lott (milos@insync.net) - * Fixed get_serial_by_minor which was all messed up for multi port - * devices. Fixed multi port problem for generic devices. Now the number - * of ports is determined by the number of bulk out endpoints for the - * generic device. - * - * (01/19/2000) gkh - * Removed lots of cruft that was around from the old (pre urb) driver - * interface. - * Made the serial_table dynamic. This should save lots of memory when - * the number of minor nodes goes up to 256. - * Added initial support for devices that have more than one port. - * Added more debugging comments for the Visor, and added a needed - * set_configuration call. - * - * (01/17/2000) gkh - * Fixed the WhiteHEAT firmware (my processing tool had a bug) - * and added new debug loader firmware for it. - * Removed the put_char function as it isn't really needed. - * Added visor startup commands as found by the Win98 dump. - * - * (01/13/2000) gkh - * Fixed the vendor id for the generic driver to the one I meant it to be. - * - * (01/12/2000) gkh - * Forget the version numbering...that's pretty useless... - * Made the driver able to be compiled so that the user can select which - * converter they want to use. This allows people who only want the Visor - * support to not pay the memory size price of the WhiteHEAT. - * Fixed bug where the generic driver (idVendor=0000 and idProduct=0000) - * grabbed the root hub. Not good. - * - * version 0.4.0 (01/10/2000) gkh - * Added whiteheat.h containing the firmware for the ConnectTech WhiteHEAT - * device. Added startup function to allow firmware to be downloaded to - * a device if it needs to be. - * Added firmware download logic to the WhiteHEAT device. - * Started to add #defines to split up the different drivers for potential - * configuration option. - * - * version 0.3.1 (12/30/99) gkh - * Fixed problems with urb for bulk out. - * Added initial support for multiple sets of endpoints. This enables - * the Handspring Visor to be attached successfully. Only the first - * bulk in / bulk out endpoint pair is being used right now. - * - * version 0.3.0 (12/27/99) gkh - * Added initial support for the Handspring Visor based on a patch from - * Miles Lott (milos@sneety.insync.net) - * Cleaned up the code a bunch and converted over to using urbs only. - * - * version 0.2.3 (12/21/99) gkh - * Added initial support for the Connect Tech WhiteHEAT converter. - * Incremented the number of ports in expectation of getting the - * WhiteHEAT to work properly (4 ports per connection). - * Added notification on insertion and removal of what port the - * device is/was connected to (and what kind of device it was). - * - * version 0.2.2 (12/16/99) gkh - * Changed major number to the new allocated number. We're legal now! - * - * version 0.2.1 (12/14/99) gkh - * Fixed bug that happens when device node is opened when there isn't a - * device attached to it. Thanks to marek@webdesign.no for noticing this. - * - * version 0.2.0 (11/10/99) gkh - * Split up internals to make it easier to add different types of serial - * converters to the code. - * Added a "generic" driver that gets it's vendor and product id - * from when the module is loaded. Thanks to David E. Nelson (dnelson@jump.net) - * for the idea and sample code (from the usb scanner driver.) - * Cleared up any licensing questions by releasing it under the GNU GPL. - * - * version 0.1.2 (10/25/99) gkh - * Fixed bug in detecting device. - * - * version 0.1.1 (10/05/99) gkh - * Changed the major number to not conflict with anything else. - * - * version 0.1 (09/28/99) gkh - * Can recognize the two different devices and start up a read from - * device when asked to. Writes also work. No control signals yet, this - * all is vendor specific data (i.e. no spec), also no control for - * different baud rates or other bit settings. - * Currently we are using the same devid as the acm driver.

It has been re-diffed against a current tree, and I also corrected a minor merging error. Some time ago we introduced a delay before device scanning, because many devices do not like to receive SCSI commands right after enumeration. Now it turns out there's a device that doesn't like to receive Get-Max-LUN right after enumeration either. Accordingly this patch delays the Get-Max-LUN request until the beginning of the scanning procedure. This fixes Bugzilla entry #5010. Three things are worth noting. First, I removed the locking code from usb_stor_acquire_resources. It's not needed, because the locking is to protect against disconnect events and acquire_resources is only called during probe (so the disconnect routine can't be called). Second, I initialized to 0 the buffer used for the Get-Max-LUN response. It's not really necessary, but it will prevent random values from showing up in the debugging log when the request fails. Third, I added a test against the SINGLE_LUN flag. This will allow us to use the flag to indicate Bulk-only devices that can't handle Get-Max-LUN.

Instead of storing a whole bunch of attributes for every single endpoint, each endpoint now gets its own kobject and they can share a static list of attributes. The number of extra fields added to struct usb_host_endpoint has been reduced from 4 to 1. The bEndpointAddress field is retained even though it is redundant (it repeats the same information as the attributes' directory name). The code avoids calling kobject_register, to prevent generating unwanted hotplug events.

Now they will correctly track along with altsetting changes. This fixes bugzilla entry #5467. In a separate but related change, when a usb_reset_configuration call fails, the device state is not changed to USB_STATE_ADDRESS. In the first place, failure means that we don't know what the state is, not that we know the device is unconfigured. In the second place, doing this can potentially lead to a memory leak, since usbcore might not realize there still is a current configuration that needs to be destroyed.

When we perform the reset, we wanted to tear down the internal data structures and rebuild them. Unfortunately, when it came to the rport structure, things were odd. If we deleted them, the scsi targets and sdevs would be torn down. Not a good thing for a temporary reset. We could block the rports, but we either maintain the internal structures to keep the rport reference (perhaps even replicating what's in the transport), or we have to fatten the fc transport with new search routines to find the rport (and deal with a case of a dangling rport that the driver forgets). It dawned on me that we had actually reached this state incorrectly. When the fc transport first started, we did the block/unblock first, then added the rport interface. The purpose of block/unblock is to hide the temporary disappearance of the rport (e.g. being deleted, then readded). Why are we making the driver do the block/unblock ? We should be making the transport have only an rport add/delete, and the let the transport handle the block/unblock. So... This patch removes the existing fc_remote_port_block/unblock functions. It moves the block/unblock functionality into the fc_remote_port_add/delete functions. Updates for the lpfc driver are included. Qlogic driver updates are also enclosed, thanks to the contributions of Andrew Vasquez. [Note: the qla2xxx changes are relative to the scsi-misc-2.6 tree as of this morning - which does not include the recent patches sent by Andrew]. The zfcp driver does not use the block/unblock functions. One last comment: The resulting behavior feels very clean. The LLDD is concerned only with add/delete, which corresponds to the physical disappearance. However, the fact that the scsi target and sdevs are not immediately torn down after the LLDD calls delete causes an interesting scenario... the midlayer can call the xxx_slave_alloc and xxx_queuecommand functions with a sdev that is at the location the rport used to be. The driver must validate the device exists when it first enters these functions. In thinking about it, this has always been the case for the LLDD and these routines. The existing drivers already check for existence. However, this highlights that simple validation via data structure dereferencing needs to be watched. To deal with this, a new transport function, fc_remote_port_chkready() was created that LLDDs should call when they first enter these two routines. It validates the rport state, and returns a scsi result which could be returned. In addition to solving the above, it also creates consistent behavior from the LLDD's when the block and deletes are occuring.

Although this is a performance booster for user applications, it is a problem for kernel. This patch explicitly instruct GCC to NOT generate altivec instructions while building the kernel. Here are some test cases I ran. (1) build gcc 4.0.1 with '--with-cpu=7450 --enable-altivec --enable-cxx-flags=-mcpu=7450', and use this gcc to build kernel WITHOUT this kernel patch. Kernel fail to boot up on a 7450 board because of altivec instructions in kernel. (2) build gcc 4.0.1 with "--with-cpu=7450 --enable-altivec --enable-cxx-flags=-mcpu=7450", and use this gcc to build kernel WITH this kernel patch. Kernel boot up on a 7450 board without any problem. (3) build gcc 4.0.1 with "--with-cpu=750 --enable-cxx-flags=-mcpu=750", and use this gcc to build kernel with or without this kernel patch. Kernel boot up on a 7450 board without any problem. This patch should also work with GCC 3 or even earlier GCC 2.95.3.

This allows mmap64() to work on /dev/mem for addresses above 4G on 32-bit architectures. We start with a pfn in mmap_mem(), so there's no need to convert to an address; in fact, it's actively bad, since the conversion can overflow when the address is above 4G. Similarly fix the ppc32 page_is_ram() function to avoid a conversion to an address by directly comparing to max_pfn. Working with max_pfn instead of high_memory fixes page_is_ram() to give the right answer for highmem pages.

Distance pointers never point before the beginning of the output - stream. - 2. Distance pointers can point back across blocks, up to 32k away. - 3. There is an implied maximum of 7 bits for the bit length table and - 15 bits for the actual data. - 4. If only one code exists, then it is encoded using one bit. (Zero - would be more efficient, but perhaps a little confusing.) If two - codes exist, they are coded using one bit each (0 and 1). - 5. There is no way of sending zero distance codes--a dummy must be - sent if there are none. (History: a pre 2.0 version of PKZIP would - store blocks with no distance codes, but this was discovered to be - too harsh a criterion.) Valid only for 1.93a. 2.04c does allow - zero distance codes, which is sent as one code of zero bits in - length. - 6. There are up to 286 literal/length codes. Code 256 represents the - end-of-block. Note however that the static length tree defines - 288 codes just to fill out the Huffman codes. Codes 286 and 287 - cannot be used though, since there is no length base or extra bits - defined for them. Similarily, there are up to 30 distance codes. - However, static trees define 32 codes (all 5 bits) to fill out the - Huffman codes, but the last two had better not show up in the data. - 7. Unzip can check dynamic Huffman blocks for complete code sets. - The exception is that a single code would not be complete (see #4). - 8. The five bits following the block type is really the number of - literal codes sent minus 257. - 9. Length codes 8,16,16 are interpreted as 13 length codes of 8 bits - (1+6+6). Therefore, to output three times the length, you output - three codes (1+1+1), whereas to output four times the same length, - you only need two codes (1+3). Hmm. - 10. In the tree reconstruction algorithm, Code = Code + Increment - only if BitLength(i) is not zero. (Pretty obvious.) - 11. Correction: 4 Bits: # of Bit Length codes - 4 (4 - 19) - 12. Note: length code 284 can represent 227-258, but length code 285 - really is 258. The last length deserves its own, short code - since it gets used a lot in very redundant files. The length - 258 is special since 258 - 3 (the min match length) is 255. - 13. The literal/length and distance code bit lengths are read as a - single stream of lengths. It is possible (and advantageous) for - a repeat code (16, 17, or 18) to go across the boundary between - the two sets of lengths. - */ - - -local void inflate_blocks_reset( - inflate_blocks_statef *s, - z_stream *z, - uLongf *c -) -{ - if (s->checkfn != Z_NULL) - *c = s->check; - if (s->mode == BTREE || s->mode == DTREE) - ZFREE(z, s->sub.trees.blens, s->sub.trees.nblens * sizeof(uInt)); - if (s->mode == CODES) - { - inflate_codes_free(s->sub.decode.codes, z); - inflate_trees_free(s->sub.decode.td, z); - inflate_trees_free(s->sub.decode.tl, z); - } - s->mode = TYPE; - s->bitk = 0; - s->bitb = 0; - s->read = s->write = s->window; - if (s->checkfn != Z_NULL) - s->check = (*s->checkfn)(0L, Z_NULL, 0); - Trace((stderr, "inflate: blocks reset\n")); -} - - -local inflate_blocks_statef *inflate_blocks_new( - z_stream *z, - check_func c, - uInt w -) -{ - inflate_blocks_statef *s; - - if ((s = (inflate_blocks_statef *)ZALLOC - (z,1,sizeof(struct inflate_blocks_state))) == Z_NULL) - return s; - if ((s->window = (Bytef *)ZALLOC(z, 1, w)) == Z_NULL) - { - ZFREE(z, s, sizeof(struct inflate_blocks_state)); - return Z_NULL; - } - s->end = s->window + w; - s->checkfn = c; - s->mode = TYPE; - Trace((stderr, "inflate: blocks allocated\n")); - inflate_blocks_reset(s, z, &s->check); - return s; -} - - -local int inflate_blocks( - inflate_blocks_statef *s, - z_stream *z, - int r -) -{ - uInt t; /* temporary storage */ - uLong b; /* bit buffer */ - uInt k; /* bits in bit buffer */ - Bytef *p; /* input data pointer */ - uInt n; /* bytes available there */ - Bytef *q; /* output window write pointer */ - uInt m; /* bytes to end of window or read pointer */ - - /* copy input/output information to locals (UPDATE macro restores) */ - LOAD - - /* process input based on current state */ - while (1) switch (s->mode) - { - case TYPE: - NEEDBITS(3) - t = (uInt)b & 7; - s->last = t & 1; - switch (t >> 1) - { - case 0: /* stored */ - Trace((stderr, "inflate: stored block%s\n", - s->last ?

However, the time it takes - to build this table can also be a factor if the data being decoded - is not very long. The most common codes are necessarily the - shortest codes, so those codes dominate the decoding time, and hence - the speed. The idea is you can have a shorter table that decodes the - shorter, more probable codes, and then point to subsidiary tables for - the longer codes. The time it costs to decode the longer codes is - then traded against the time it takes to make longer tables. - - This results of this trade are in the variables lbits and dbits - below. lbits is the number of bits the first level table for literal/ - length codes can decode in one step, and dbits is the same thing for - the distance codes. Subsequent tables are also less than or equal to - those sizes. These values may be adjusted either when all of the - codes are shorter than that, in which case the longest code length in - bits is used, or when the shortest code is *longer* than the requested - table size, in which case the length of the shortest code in bits is - used. - - There are two different values for the two tables, since they code a - different number of possibilities each. The literal/length table - codes 286 possible values, or in a flat code, a little over eight - bits. The distance table codes 30 possible values, or a little less - than five bits, flat. The optimum values for speed end up being - about one bit more than those, so lbits is 8+1 and dbits is 5+1. - The optimum values may differ though from machine to machine, and - possibly even between compilers.

If a compressed stream - with a larger window size is given as input, inflate() will return with - the error code Z_DATA_ERROR instead of trying to allocate a larger window. - - If next_out is not null, the library will use this buffer for the history - buffer; the buffer must either be large enough to hold the entire output - data, or have at least 1< Date: Fri, 28 Oct 2005 17:46:40 -0700 Subject: [PATCH] ppc64 boot: remove need for imagesize.c Compute the vmlinux size at runtime. Use Z_FULL_FLUSH instead of Z_FINISH, to extract only the ELF header and ELF program header. ->p_memsz is the required memory range for the executable, including bss ->p_filesz is the size of .text, .data and other runtime sections These values must be used for the claim call. All additional memory needed by the kernel is claimed in prom_init, remove the extra Mb. Pass the full memsize as target area to gunzip, otherwise not everything will be uncompressed. flush_cache has to flush all runtime sections, do not reduce the memrange by the ->p_offset value because its just that: an offset. Remove the Makefile code to produce an imagesize.c, its not needed anymore. Remove all FORCE flags, to not rebuild the zImage if vmlinux was not changed.

It uses the second arg as file content, which is the vmlinux, and the 5th arg as file name, which is the BOOTIMAGE name. A comment in an earlier patch to install.sh states that yaboot can not load a zImage+initrd combo. This was true in kernel 2.6.5 because it did use bi_recs to pass the initrd info. But this concept was always broken. Register r3 holds the initrd address and r4 holds the initrd size. This works with all kernel versions. The current code in main.c leaves r3 and r4 alone, so the kernel should be able to see and use the memory range with the initrd content. If one wants to rerun mkinitrd, it is currently hard to get the uname -r value for the installed zImage. Without this info, mkinitrd can not know what modules to use. This would be fixable by including the /proc/version output of the new kernel. But it is simpler to just use the plain vmlinux.

Specifically, -// every time a link re-init (e.g. LIP) takes place, all SCSI I/O has to be -// suspended until the login sequences have been completed. Login commands -// are frames just like SCSI commands are frames; they are subject to the same -// timeout issues and delays. Also, various specs provide up to 2 seconds for -// devices to log back in (i.e. respond with ACC to a login frame), so I/O to -// that device has to be suspended. -// A serious problem here occurs on highly loaded FC-AL systems. If our FC port -// has a low priority (e.g. high arbitrated loop physical address, alpa), and -// some other device is hogging bandwidth (permissible under FC-AL), we might -// time out thinking the link is hung, when it's simply busy. Many such -// considerations complicate the design. Although Tachyon assumes control -// (in silicon) for many link-specific issues, the Linux driver is left with the -// rest, which turns out to be a difficult, time critical chore. - -// These "worker" functions will handle things like FC Logins; all -// processes with I/O to our device must wait for the Login to complete -// and (if successful) I/O to resume. In the event of a malfunctioning or -// very busy loop, it may take hundreds of millisecs or even seconds to complete -// a frame send. We don't want to hang up the entire server (and all -// processes which don't depend on Fibre) during this wait. - -// The Tachyon chip can have around 30,000 I/O operations ("exchanges") -// open at one time. However, each exchange must be initiated -// synchronously (i.e. each of the 30k I/O had to be started one at a -// time by sending a starting frame via Tachyon's outbound que). - -// To accommodate kernel "module" build, this driver limits the exchanges -// to 256, because of the contiguous physical memory limitation of 128M. - -// Typical FC Exchanges are opened presuming the FC frames start without errors, -// while Exchange completion is handled in the interrupt handler. This -// optimizes performance for the "everything's working" case. -// However, when we have FC related errors or hot plugging of FC ports, we pause -// I/O and handle FC-specific tasks in the worker thread. These FC-specific -// functions will handle things like FC Logins and Aborts. As the Login sequence -// completes to each and every target, I/O can resume to that target. - -// Our kernel "worker thread" must share the HBA with threads calling -// "queuecommand". We define a "BoardLock" semaphore which indicates -// to "queuecommand" that the HBA is unavailable, and Cmnds are added to a -// board lock Q. When the worker thread finishes with the board, the board -// lock Q commands are completed with status causing immediate retry. -// Typically, the board is locked while Logins are in progress after an -// FC Link Down condition. When Cmnds are re-queued after board lock, the -// particular Scsi channel/target may or may not have logged back in. When -// the device is waiting for login, the "prli" flag is clear, in which case -// commands are passed to a Link Down Q. Whenever the login finally completes, -// the LinkDown Q is completed, again with status causing immediate retry. -// When FC devices are logged in, we build and start FC commands to the -// devices. - -// NOTE!!

But XCB=101 mappings are write-buffered while mappings using XCB=000 are not, which is why if we use XCB=101 mappings we do a readback for every CSR store in an attempt to make sure that the store has been pushed out of the xscale core and the gasket. Unfortunately, there are two issues with this: - we do a readback for every CSR store, which is wrong, because the register we are writing to might have unwanted side-effects on read, for example, in the case of the scratchpad ring enqueue/dequeue registers; and - the readback is totally ineffective in the way we currently do it, because we just issue a load but do not issue any instruction that depends on the return value of that load, so the xscale core does not wait for the load to complete before continuing. See this linux-arm-kernel mailing list post for further information: http://lists.arm.linux.org.uk/pipermail/linux-arm-kernel/2005-September/031314.html This means that my ixp2400 boxes have been running for many months without a working readback in ixp2000_reg_write, without any apparent adverse effects. Two of them have been running for a week now with the actual readback deleted from ixp2000_reg_write, also without any apparent ill effects. So, because in its current form it does more harm than good, the readback in ixp2000_reg_write should simply be killed, as the patch below does.

It links together aliased requests using rq->queuelist instead of spilling alises to dispatch queue like other ioscheds do. Requests linked in this way cannot be merged. Unfortunately, generic q->last_merge handling patch didn't take this into account and q->last_merge could be set to an aliased request resulting in Badness, corrupt list and eventually panic.

Biederman" Date: Sun, 30 Oct 2005 15:02:08 -0800 Subject: [PATCH] Don't uselessly export task_struct to userspace in core dumps task_struct is an internal structure to the kernel with a lot of good information, that is probably interesting in core dumps. However there is no way for user space to know what format that information is in making it useless. I grepped the GDB 6.3 source code and NT_TASKSTRUCT while defined is not used anywhere else. So I would be surprised if anyone notices it is missing. In addition exporting kernel pointers to all the interesting kernel data structures sounds like the very definition of an information leak. I haven't a clue what someone with evil intentions could do with that information, but in any attack against the kernel it looks like this is the perfect tool for aiming that attack. So since NT_TASKSTRUCT is useless as currently defined and is potentially dangerous, let's just not export it. (akpm: Daniel Jacobowitz "would be amazed" if anything was using NT_TASKSTRUCT).

Replace single semaphore with two semaphores. The suggestion to use two locks was made by Roman Zippel. Both locks are global. Code that wants to modify cpusets must first acquire the exclusive manage_sem, which allows them read-only access to cpusets, and holds off other would-be modifiers. Before making actual changes, the second semaphore, callback_sem must be acquired as well. Code that needs only to query cpusets must acquire callback_sem, which is also a global exclusive lock. The earlier problems with double tripping are avoided, because it is allowed for holders of manage_sem to nest the second callback_sem lock, and only callback_sem is needed by code called from within __alloc_pages(), where the double tripping had been possible. This is not quite the same as a normal read/write semaphore, because obtaining read-only access with intent to change must hold off other such attempts, while allowing read-only access w/o such intention. Changing cpusets involves several related checks and changes, which must be done while allowing read-only queries (to avoid the double trip), but while ensuring nothing changes (holding off other would be modifiers.) This overhaul of cpuset locking also makes careful use of task_lock() to guard access to the task->cpuset pointer, closing a couple of race conditions noticed while reading this code (thanks, Roman). I've never seen these races fail in any use or test. See further the comments in the code.

Only allow simple rename of cpuset directories in place. Don't allow moving cpusets elsewhere in hierarchy or renaming the special cpuset files in each cpuset directory. The usefulness of this simple rename became apparent when developing task migration facilities. It allows building a second cpuset hierarchy using new names and containing new CPUs and Memory Nodes, moving tasks from the old to the new cpusets, removing the old cpusets, and then renaming the new cpusets to be just like the old names, so that any knowledge that the tasks had of their cpuset names will still be valid. Leaf node cpusets can be migrated to other CPUs or Memory Nodes by just updating their 'cpus' and 'mems' files, but because no cpuset can contain CPUs or Nodes not in its parent cpuset, one cannot do this in a cpuset hierarchy without first expanding all the non-leaf cpusets to contain the union of both the old and new CPUs and Nodes, which would obfuscate the one-to-one migration of a task from one cpuset to another required to correctly migrate the physical page frames currently allocated to that task.

Some large NUMA configurations put as much as they can of kernel threads and other classic Unix load in what's called a bootcpuset, keeping the rest of the system free for dedicated jobs. This effort is thwarted by pdflush, which dynamically destroys and recreates pdflush daemons depending on load. It's easy enough to force the originally created pdflush deamons into the bootcpuset, at system boottime. But the pdflush threads created later were allowed to run freely across the system, due to the necessary line in their startup kthread(): set_cpus_allowed(current, CPU_MASK_ALL); By simply coding pdflush to start its threads with the cpus_allowed restrictions of its cpuset (inherited from kthread, its parent) we can ensure that dynamically created pdflush threads are also kept in the bootcpuset. On systems w/o cpusets, or w/o a bootcpuset implementation, the following will have no affect, leaving pdflush to run on any CPU, as before.

For example, if a task and its pages on nodes 8-11 are being migrated to nodes 24-27, then pages on node 9 (the 2nd node in the old set) should be moved to node 25 (the 2nd node in the new set.) As with other bitmap operations, the proper way to code this is to provide the underlying calculation in lib/bitmap.c, and then to provide the usual cpumask and nodemask wrappers. This patch provides that. These operations are termed 'remap' operations. Both remapping a single bit and a set of bits is supported.

It does so within the context of the task, without any need to support low level external mempolicy manipulation. If a system is not using cpusets, or if running on a system with just the root (all-encompassing) cpuset, then this remap is a no-op. Only when a task is moved between cpusets, or a cpusets memory placement is changed does the following apply. Otherwise, the main routine below, rebind_policy() is not even called. When mixing cpusets, scheduler affinity, and NUMA mempolicies, the essential role of cpusets is to place jobs (several related tasks) on a set of CPUs and Memory Nodes, the essential role of sched_setaffinity is to manage a jobs processor placement within its allowed cpuset, and the essential role of NUMA mempolicy (mbind, set_mempolicy) is to manage a jobs memory placement within its allowed cpuset. However, CPU affinity and NUMA memory placement are managed within the kernel using absolute system wide numbering, not cpuset relative numbering. This is ok until a job is migrated to a different cpuset, or what's the same, a jobs cpuset is moved to different CPUs and Memory Nodes. Then the CPU affinity and NUMA memory placement of the tasks in the job need to be updated, to preserve their cpuset-relative position. This can be done for CPU affinity using sched_setaffinity() from user code, as one task can modify anothers CPU affinity. This cannot be done from an external task for NUMA memory placement, as that can only be modified in the context of the task using it. However, it easy enough to remap a tasks NUMA mempolicy automatically when a task is migrated, using the existing cpuset mechanism to trigger a refresh of a tasks memory placement after its cpuset has changed. All that is needed is the old and new nodemask, and notice to the task that it needs to rebind its mempolicy. The tasks mems_allowed has the old mask, the tasks cpuset has the new mask, and the existing cpuset_update_current_mems_allowed() mechanism provides the notice. The bitmap/cpumask/nodemask remap operators provide the cpuset relative calculations. This patch leaves open a couple of issues: 1) Updating vma and shmfs/tmpfs/hugetlbfs memory policies: These mempolicies may reference nodes outside of those allowed to the current task by its cpuset. Tasks are migrated as part of jobs, which reside on what might be several cpusets in a subtree. When such a job is migrated, all NUMA memory policy references to nodes within that cpuset subtree should be translated, and references to any nodes outside that subtree should be left untouched. A future patch will provide the cpuset mechanism needed to mark such subtrees. With that patch, we will be able to correctly migrate these other memory policies across a job migration. 2) Updating cpuset, affinity and memory policies in user space: This is harder. Any placement state stored in user space using system-wide numbering will be invalidated across a migration. More work will be required to provide user code with a migration-safe means to manage its cpuset relative placement, while preserving the current API's that pass system wide numbers, not cpuset relative numbers across the kernel-user boundary.

This originated from a gdb bugreport (the fact gdb was segfaulting the task wasn't a kernel bug), but I just incidentally noticed the gdb bug triggered a real kernel bug as well. Most threads hangs in exit_mm because the core_dumping is still going, the core dumping hangs because the stopped task doesn't exit, the stopped task can't wakeup because it has SIGNAL_GROUP_EXIT set, hence the deadlock. To me it seems that the problem is that the force_sig_specific(SIGKILL) in zap_threads is a noop if the task has PF_PTRACED set (like in this case because gdb is attached). The __ptrace_unlink does nothing because the signal->flags is set to SIGNAL_GROUP_EXIT|SIGNAL_STOP_DEQUEUED (verified). The above info also shows that the stopped task hit a race and got the stop signal (presumably by the ptrace_attach, only the attach, state is still TASK_STOPPED and gdb hangs waiting the core before it can set it to TASK_TRACED) after one of the thread invoked the core dump (it's the core dump that sets signal->flags to SIGNAL_GROUP_EXIT). So beside the fact nobody would wakeup the task in __ptrace_unlink (the state is _not_ TASK_TRACED), there's a secondary problem in the signal handling code, where a task should ignore the ptrace-sigstops as long as SIGNAL_GROUP_EXIT is set (or the wakeup in __ptrace_unlink path wouldn't be enough). So I attempted to make this patch that seems to fix the problem. There were various ways to fix it, perhaps you prefer a different one, I just opted to the one that looked safer to me. I also removed the clearing of the stopped bits from the zap_other_threads (zap_other_threads was safe unlike zap_threads). I don't like useless code, this whole NPTL signal/ptrace thing is already unreadable enough and full of corner cases without confusing useless code into it to make it even less readable. And if this code is really needed, then you may want to explain why it's not being done in the other paths that sets SIGNAL_GROUP_EXIT at least. Even after this patch I still wonder who serializes the read of p->ptrace in zap_threads. Patch is called ptrace-core_dump-exit_group-deadlock-1.

This patch makes __generic_file_aio_read()'s error handling identical to other functions. #include #include #include #include #include #include #include #include #include int main(int argc, char **argv) { const char *path; struct stat stbuf; size_t len0, len1; void *buf0, *buf1; struct iovec iov[3]; int fd, i; ssize_t ret; if (argc < 2) { fprintf(stderr, "Usage: testreadv path (better be a " "small text file)\n"); return 1; } path = argv[1]; if (stat(path, &stbuf) < 0) { perror("stat"); return 1; } len0 = stbuf.st_size / 2; len1 = stbuf.st_size - len0; if (!len0 || !len1) { fprintf(stderr, "Dude, file is too small\n"); return 1; } if ((fd = open(path, O_RDONLY)) < 0) { perror("open"); return 1; } if (!(buf0 = malloc(len0)) || !(buf1 = malloc(len1))) { perror("malloc"); return 1; } memset(buf0, 0, len0); memset(buf1, 0, len1); iov[0].iov_base = buf0; iov[0].iov_len = len0; iov[1].iov_base = NULL; iov[1].iov_len = len1; iov[2].iov_base = buf1; iov[2].iov_len = len1; printf("vector "); for (i = 0; i < 3; i++) printf("%p:%zu ", iov[i].iov_base, iov[i].iov_len); printf("\n"); ret = readv(fd, iov, 3); if (ret < 0) perror("readv"); printf("readv returned %zd\nbuf0 = [%s]\nbuf1 = [%s]\n", ret, (char *)buf0, (char *)buf1); return 0; } Signed-off-by: Tejun Heo Cc: Benjamin LaHaise Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds diff --git a/mm/filemap.c b/mm/filemap.c index 768687f..5d6e4c2 100644 --- a/mm/filemap.c +++ b/mm/filemap.c @@ -1030,8 +1030,8 @@ __generic_file_aio_read(struct kiocb *iocb, const struct iovec *iov, desc.error = 0; do_generic_file_read(filp,ppos,&desc,file_read_actor); retval += desc.written; - if (!retval) { - retval = desc.error; + if (desc.error) { + retval = retval ?: desc.error; break; } } -- cgit v0.10.2 From c7e9dd4dd0b8dd75c410011b3c8f9980112fd0f8 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Sun, 30 Oct 2005 15:02:40 -0800 Subject: [PATCH] vm: remove redundant assignment from __pagevec_release_nonlru() This patch removes redundant assignment from __pagevec_release_nonlru(). pages_to_free.cold is set to pvec->cold by pagevec_init() call right above the assignment.

The notable changes are: (1) The key struct now supports a security pointer for the use of security modules. This will permit key labelling and restrictions on which programs may access a key. (2) Security modules get a chance to note (or abort) the allocation of a key. (3) The key permission checking can now be enhanced by the security modules; the permissions check consults LSM if all other checks bear out. (4) The key permissions checking functions now return an error code rather than a boolean value. (5) An extra permission has been added to govern the modification of attributes (UID, GID, permissions). Note that there isn't an LSM hook specifically for each keyctl() operation, but rather the permissions hook allows control of individual operations based on the permission request bits. Key management access control through LSM is enabled by automatically if both CONFIG_KEYS and CONFIG_SECURITY are enabled.

The only additional danger operations that debug code introduces seems to be related to bitmap, but bitmap operations tends to be all atomic anyway.

It was added somewhere between 2.6.5 and 2.6.8. I think it's wrong. The only way I can imagine the i_count to be zero in the above path, is that I_WILL_FREE is set. And if I_WILL_FREE is set, then we must not increase nr_unused. So I believe the above change is buggy and it will definitely overstate the number of unused inodes and it should be backed out. Note that __writeback_single_inode before calling __sync_single_inode, can drop the spinlock and we can have both the dirty and locked bitflags clear here: spin_unlock(&inode_lock); __wait_on_inode(inode); iput(inode); XXXXXXX spin_lock(&inode_lock); } use inode again here a construct like the above makes zero sense from a reference counting standpoint. Either we don't ever use the inode again after the iput, or the inode_lock should be taken _before_ executing the iput (i.e. a __iput would be required). Taking the inode_lock after iput means the iget was useless if we keep using the inode after the iput. So the only chance the 2.6 was safe to call __writeback_single_inode with the i_count == 0, is that I_WILL_FREE is set (I_WILL_FREE will prevent the VM to free the inode in XXXXX). Potentially calling the above iput with I_WILL_FREE was also wrong because it would recurse in iput_final (the second mainline bug). The below (untested) patch fixes the nr_unused accounting, avoids recursing in iput when I_WILL_FREE is set and makes sure (with the BUG_ON) that we don't corrupt memory and that all holders that don't set I_WILL_FREE, keeps a reference on the inode!

You can test this by writing something with the bright set to the console, for example: echo -e "\e[1;31mhello there\e[0m" and then wait for the console to blank itself (by default, after 10 mins of inactivity), maybe making it faster using setterm -blank 1 so you only have to wait 1 minute.

This rewrite adds a tristate CONFIG_RCU_TORTURE_TEST, which enables an intense torture test of the RCU infratructure. This is needed due to the continued changes to the RCU infrastructure to accommodate dynamic ticks, CPU hotplug, realtime, and so on. Most of the code is in a separate file that is compiled only if the CONFIG variable is set. Documentation on how to run the test and interpret the output is also included. This code has been tested on i386 and ppc64, and an earlier version of the code has received extensive testing on a number of architectures as part of the PREEMPT_RT patchset. Signed-off-by: "Paul E.

It creates an rcutorture kernel module that can +be loaded to run a torture test. The test periodically outputs +status messages via printk(), which can be examined via the dmesg +command (perhaps grepping for "rcutorture"). The test is started +when the module is loaded, and stops when the module is unloaded. + +However, actually setting this config option to "y" results in the system +running the test immediately upon boot, and ending only when the system +is taken down. Normally, one will instead want to build the system +with CONFIG_RCU_TORTURE_TEST=m and to use modprobe and rmmod to control +the test, perhaps using a script similar to the one shown at the end of +this document. Note that you will need CONFIG_MODULE_UNLOAD in order +to be able to end the test. + + +MODULE PARAMETERS + +This module has the following parameters: + +nreaders This is the number of RCU reading threads supported. + The default is twice the number of CPUs. Why twice? + To properly exercise RCU implementations with preemptible + read-side critical sections. + +stat_interval The number of seconds between output of torture + statistics (via printk()). Regardless of the interval, + statistics are printed when the module is unloaded. + Setting the interval to zero causes the statistics to + be printed -only- when the module is unloaded, and this + is the default. + +verbose Enable debug printk()s. Default is disabled. + + +OUTPUT + +The statistics output is as follows: + + rcutorture: --- Start of test: nreaders=16 stat_interval=0 verbose=0 + rcutorture: rtc: 0000000000000000 ver: 1916 tfle: 0 rta: 1916 rtaf: 0 rtf: 1915 + rcutorture: Reader Pipe: 1466408 9747 0 0 0 0 0 0 0 0 0 + rcutorture: Reader Batch: 1464477 11678 0 0 0 0 0 0 0 0 + rcutorture: Free-Block Circulation: 1915 1915 1915 1915 1915 1915 1915 1915 1915 1915 0 + rcutorture: --- End of test + +The command "dmesg | grep rcutorture:" will extract this information on +most systems. On more esoteric configurations, it may be necessary to +use other commands to access the output of the printk()s used by +the RCU torture test. The printk()s use KERN_ALERT, so they should +be evident. ;-) + +The entries are as follows: + +o "ggp": The number of counter flips (or batches) since boot. + +o "rtc": The hexadecimal address of the structure currently visible + to readers. + +o "ver": The number of times since boot that the rcutw writer task + has changed the structure visible to readers. + +o "tfle": If non-zero, indicates that the "torture freelist" + containing structure to be placed into the "rtc" area is empty. + This condition is important, since it can fool you into thinking + that RCU is working when it is not. :-/ + +o "rta": Number of structures allocated from the torture freelist. + +o "rtaf": Number of allocations from the torture freelist that have + failed due to the list being empty. + +o "rtf": Number of frees into the torture freelist. + +o "Reader Pipe": Histogram of "ages" of structures seen by readers. + If any entries past the first two are non-zero, RCU is broken. + And rcutorture prints the error flag string "!!!" to make sure + you notice. The age of a newly allocated structure is zero, + it becomes one when removed from reader visibility, and is + incremented once per grace period subsequently -- and is freed + after passing through (RCU_TORTURE_PIPE_LEN-2) grace periods. + + The output displayed above was taken from a correctly working + RCU. If you want to see what it looks like when broken, break + it yourself. ;-) + +o "Reader Batch": Another histogram of "ages" of structures seen + by readers, but in terms of counter flips (or batches) rather + than in terms of grace periods. The legal number of non-zero + entries is again two. The reason for this separate view is + that it is easier to get the third entry to show up in the + "Reader Batch" list than in the "Reader Pipe" list. + +o "Free-Block Circulation": Shows the number of torture structures + that have reached a given point in the pipeline. The first element + should closely correspond to the number of structures allocated, + the second to the number that have been removed from reader view, + and all but the last remaining to the corresponding number of + passes through a grace period. The last entry should be zero, + as it is only incremented if a torture structure's counter + somehow gets incremented farther than it should. + + +USAGE + +The following script may be used to torture RCU: + + #!/bin/sh + + modprobe rcutorture + sleep 100 + rmmod rcutorture + dmesg | grep rcutorture: + +The output can be manually inspected for the error flag of "!!!". +One could of course create a more elaborate script that automatically +checked for such errors. diff --git a/include/linux/rcupdate.h b/include/linux/rcupdate.h index 70191a5..cce2559 100644 --- a/include/linux/rcupdate.h +++ b/include/linux/rcupdate.h @@ -275,6 +275,7 @@ static inline int rcu_pending(int cpu) extern void rcu_init(void); extern void rcu_check_callbacks(int cpu, int user); extern void rcu_restart_cpu(int cpu); +extern long rcu_batches_completed(void); /* Exported interfaces */ extern void FASTCALL(call_rcu(struct rcu_head *head, diff --git a/kernel/Makefile b/kernel/Makefile index 980b5e4..4f5a145 100644 --- a/kernel/Makefile +++ b/kernel/Makefile @@ -31,6 +31,7 @@ obj-$(CONFIG_DETECT_SOFTLOCKUP) += softlockup.o obj-$(CONFIG_GENERIC_HARDIRQS) += irq/ obj-$(CONFIG_CRASH_DUMP) += crash_dump.o obj-$(CONFIG_SECCOMP) += seccomp.o +obj-$(CONFIG_RCU_TORTURE_TEST) += rcutorture.o ifneq ($(CONFIG_SCHED_NO_NO_OMIT_FRAME_POINTER),y) # According to Alan Modra , the -fno-omit-frame-pointer is diff --git a/kernel/rcupdate.c b/kernel/rcupdate.c index 2559d4b..c4d159a 100644 --- a/kernel/rcupdate.c +++ b/kernel/rcupdate.c @@ -154,6 +154,15 @@ void fastcall call_rcu_bh(struct rcu_head *head, } /* + * Return the number of RCU batches processed thus far.

In the typical case of a 14.32 MHz timer, this happens when the desired frequency exceeds 61 Hz. To avoid this multiplication, we can precompute and store the hardware timer frequency, instead of the period, in the device structure, which leaves us with a simple division when computing the number of timer ticks. As a side effect, this also removes a theoretical bug where the timer interpolator's frequency would be computed as a 32-bit value even if the HPET frequency is greater than 2^32 Hz (the HPET spec allows up to 10 GHz).

This reduces the number of indirect includes of sched.h by ~300. Another ~400 pointless direct includes can be removed after this disentangling (patch to follow later). However, quite a few indirect includes need to be fixed up for this. In order to feed the patches through -mm with as little disturbance as possible, I've split out the fixes I accumulated up to now (complete for i386 and x86_64, more archs to follow later) and post them before the real patch. This way this large part of the patch is kept simple with only adding #includes, and all hunks are independent of each other. So if any hunk rejects or gets in the way of other patches, just drop it. My scripts will pick it up again in the next round.

This change eliminates the sharing between our controller-wide spinlock and the SCSI core's Scsi_Host lock. As the locking in libata was already highly compartmentalized, always referencing our own lock, and never scsi_host::host_lock. As a side effect, this change eliminates a deadlock from calling scsi_finish_command() while inside our spinlock. diff --git a/drivers/scsi/libata-core.c b/drivers/scsi/libata-core.c index a17e120..ff18fa7 100644 --- a/drivers/scsi/libata-core.c +++ b/drivers/scsi/libata-core.c @@ -4089,8 +4089,6 @@ static void ata_host_init(struct ata_port *ap, struct Scsi_Host *host, host->unique_id = ata_unique_id++; host->max_cmd_len = 12; - scsi_assign_lock(host, &host_set->lock); - ap->flags = ATA_FLAG_PORT_DISABLED; ap->id = host->unique_id; ap->host = host; diff --git a/drivers/scsi/libata-scsi.c b/drivers/scsi/libata-scsi.c index 1e3792f..248baae 100644 --- a/drivers/scsi/libata-scsi.c +++ b/drivers/scsi/libata-scsi.c @@ -39,6 +39,7 @@ #include #include "scsi.h" #include +#include #include #include #include @@ -2405,8 +2406,12 @@ int ata_scsi_queuecmd(struct scsi_cmnd *cmd, void (*done)(struct scsi_cmnd *)) struct ata_port *ap; struct ata_device *dev; struct scsi_device *scsidev = cmd->device; + struct Scsi_Host *shost = scsidev->host; - ap = (struct ata_port *) &scsidev->host->hostdata[0]; + ap = (struct ata_port *) &shost->hostdata[0]; + + spin_unlock(shost->host_lock); + spin_lock(&ap->host_set->lock); ata_scsi_dump_cdb(ap, cmd); @@ -2429,6 +2434,8 @@ int ata_scsi_queuecmd(struct scsi_cmnd *cmd, void (*done)(struct scsi_cmnd *)) ata_scsi_translate(ap, dev, cmd, done, atapi_xlat); out_unlock: + spin_unlock(&ap->host_set->lock); + spin_lock(shost->host_lock); return 0; } -- cgit v0.10.2 From e0be618d1e8ed0a1a94ee14025ec5e3022d2ec5b Mon Sep 17 00:00:00 2001 From: Dmitry Torokhov Date: Mon, 31 Oct 2005 01:29:23 -0500 Subject: Input: evdev - allow querying EV_SW bits from compat_ioctl Signed-off-by: Dmitry Torokhov diff --git a/drivers/input/evdev.c b/drivers/input/evdev.c index a4696cd..d64d029 100644 --- a/drivers/input/evdev.c +++ b/drivers/input/evdev.c @@ -565,6 +565,7 @@ static long evdev_ioctl_compat(struct file *file, unsigned int cmd, unsigned lon case EV_LED: bits = dev->ledbit; max = LED_MAX; break; case EV_SND: bits = dev->sndbit; max = SND_MAX; break; case EV_FF: bits = dev->ffbit; max = FF_MAX; break; + case EV_SW: bits = dev->swbit; max = SW_MAX; break; default: return -EINVAL; } bit_to_user(bits, max); -- cgit v0.10.2 From 7972720aaa044d0bca40e2e1d4c176076a9f0e00 Mon Sep 17 00:00:00 2001 From: Dmitry Torokhov Date: Mon, 31 Oct 2005 01:29:37 -0500 Subject: Input: evdev - allow querying SW state from compat ioctl Signed-off-by: Dmitry Torokhov diff --git a/drivers/input/evdev.c b/drivers/input/evdev.c index d64d029..9f2352bd 100644 --- a/drivers/input/evdev.c +++ b/drivers/input/evdev.c @@ -580,6 +580,9 @@ static long evdev_ioctl_compat(struct file *file, unsigned int cmd, unsigned lon if (_IOC_NR(cmd) == _IOC_NR(EVIOCGSND(0))) bit_to_user(dev->snd, SND_MAX); + if (_IOC_NR(cmd) == _IOC_NR(EVIOCGSW(0))) + bit_to_user(dev->sw, SW_MAX); + if (_IOC_NR(cmd) == _IOC_NR(EVIOCGNAME(0))) { int len; if (!dev->name) return -ENOENT; -- cgit v0.10.2 From 995fc4df0bc8d88417742e4b1d17889fc64b6ef3 Mon Sep 17 00:00:00 2001 From: Dmitry Torokhov Date: Mon, 31 Oct 2005 01:29:51 -0500 Subject: Input: fix input_dev registration message Signed-off-by: Dmitry Torokhov diff --git a/drivers/input/input.c b/drivers/input/input.c index 3b1685f..1a1654c 100644 --- a/drivers/input/input.c +++ b/drivers/input/input.c @@ -730,7 +730,7 @@ static void input_register_classdevice(struct input_dev *dev) "input%ld", (unsigned long) atomic_inc_return(&input_no) - 1); path = kobject_get_path(&dev->cdev.class->subsys.kset.kobj, GFP_KERNEL); - printk(KERN_INFO "input: %s/%s as %s\n", + printk(KERN_INFO "input: %s as %s/%s\n", dev->name ?

The problem is that we are using the generic dispatch queue directly in the noop sched and merging is NOT allowed on dispatch queues but generic handling of last_merge tries to merge requests. I'm still trying to verify this, so I'll be back with results soon." In the meantime, disable merging for noop by setting REQ_NOMERGE in elevator_noop_add_request().

Since the driver didn't initiate the I/O, the data in it's internal tables will contain NULL pointers. When this condition is detected, a "flush cache and reset" is performed. The flush cache allows any pending "lazy writes" that the adapter is processing to complete ( a "must have" for a RAID adapter ) and the reset puts the adapter back into a known, good state.

The merge is essentially trivial, since the structure defined in each version was already identical. Only wrinkle is that the merged version now includes linux/types.h in order to get the fixed width integer types. In fact, the old versions probably should have been including that anyway, since the file uses various __kernel_*_t types. Built and booted on G5, built for 32-bit pmac, but not booted, since the merge tree currently doesn't boot there.

This re-introduces the set_bits() function from ppc64, which I removed because I thought it was unused (it exists on no other arch). In fact it is used in the powermac interrupt code (but not on pSeries). - We use LARXL/STCXL macros to generate the right (32 or 64 bit) instructions, similar to LDL/STL from ppc_asm.h, used in fpu.S - ppc32 previously used a full "sync" barrier at the end of test_and_*_bit(), whereas ppc64 used an "isync". The merged version uses "isync", since I believe that's sufficient. - The ppc64 versions of then minix_*() bitmap functions have changed semantics. Previously on ppc64, these functions were big-endian (that is bit 0 was the LSB in the first 64-bit, big-endian word). On ppc32 (and x86, for that matter, they were little-endian. As far as I can tell, the big-endian usage was simply wrong - I guess no-one ever tried to use minixfs on ppc64. - On ppc32 find_next_bit() and find_next_zero_bit() are no longer inline (they were already out-of-line on ppc64). - For ppc64, sched_find_first_bit() has moved from mmu_context.h to the merged bitops. What it was doing in mmu_context.h in the first place, I have no idea. - The fls() function is now implemented using the cntlzw instruction on ppc64, instead of generic_fls(), as it already was on ppc32. - For ARCH=ppc, this patch requires adding arch/powerpc/lib to the arch/ppc/Makefile. This in turn requires some changes to arch/powerpc/lib/Makefile which didn't correctly handle ARCH=ppc. Built and running on G5.

It is made of two levels: a template that consists of the core copy code and separate files that define macros to be used with the core code depending on the type of copy needed. This allows for best performances while sharing the same core for implementing memcpy(), copy_from_user() and copy_to_user() for instance. Two reasons for this work: 1) the current copy_to_user/copy_from_user implementation assumes no task switch will ever occur in the middle of each copied page making it completely unsafe with CONFIG_PREEMPT=y. 2) current copy implementations are measurably suboptimal and optimizing different implementations separately is a pain and more opportunities for bugs. The reason for (1) is the fact that copy inside user pages are performed with the ldm instruction which has no mean for testing user protections and could possibly race with process preemption bypassing the COW mechanism for example. This is a longstanding issue that we said ought to be fixed for about two years now. The solution is to substitute those ldm insns with a series of ldrt or strt insns to enforce user memory protection. At least on StrongARM and XScale cores the ldm is not faster than the equivalent ldr/str insns with a warm i-cache so there is no measurable performance degradation with that change. The fact that the copy code is a template makes it pretty easy to reuse the same core code as for memcpy and benefit from the same performance optimizations. Now (2) is best demonstrated with actual throughput measurements. First, here is a summary of memcopy tests performed on a StrongARM core: PTR alignment buffer size kernel version this version ------------------------------------------------------------ aligned 32 59.73 107.43 unaligned 32 61.31 74.72 aligned 100 132.47 136.15 unaligned 100 103.84 123.76 aligned 4096 130.67 130.80 unaligned 4096 130.68 130.64 aligned 1048576 68.03 68.18 unaligned 1048576 68.03 68.18 The buffer size is in bytes and the measured speed in MB/s. The copy was performed repeatedly with given buffer and throughput averaged over 3 seconds. Here we can see that the current kernel version has a higher entry cost that shows up with small buffers. As buffer size grows both implementation converge to the same throughput. Now here's the exact same test performed on an XScale core (PXA255): PTR alignment buffer size kernel version this version ------------------------------------------------------------ aligned 32 46.99 77.58 unaligned 32 53.61 59.59 aligned 100 107.19 136.59 unaligned 100 83.61 97.58 aligned 4096 129.13 129.98 unaligned 4096 128.36 128.53 aligned 1048576 53.76 59.41 unaligned 1048576 33.67 56.96 Again we can see the entry setup cost being higher for the current kernel before getting to the main copy loop. Then throughput results converge as long as the buffer remains in the cache. Then the 1MB case shows more differences probably due to better pld placement and/or less instruction interlocks in this proposed implementation. Disclaimer: The PXA system was running with slower clocks than the StrongARM system so trying to infer any conclusion by comparing those separate sets of results side by side would be completely inappropriate. So... What this patch does is to replace both memcpy and memmove with an implementation based on the provided copy code template. The memmove code is kept separate since it is used only if the memory areas involved do overlap in which case the code is a transposition of the template but with the copy occurring in the opposite direction (trying to fit that mode into the template turned it into a mess not worth it for memmove alone). And obviously both memcpy and memmove were tested with all kinds of pointer alignments and buffer sizes to exercise all code paths for correctness. The next patch will provide the now trivial replacement implementation copy_to_user and copy_from_user.

It is enabled unconditionally when CONFIG_PREEMPT=y. Otherwise if the configured architecture is not ARMv3 then it is enabled as well as it gives better performances at least on StrongARM and XScale cores.

The ixp2000 is an xscale-based CPU with a number of additional small CPUs ('microengines') on die that can be programmed to do various things. Depending on the ixp2000 model, there are between 2 and 16 microengines. This code provides an API that allows configuring the microengines, loading code into them, and starting and stopping them and reading out a number of status registers, and is used by the microengine network driver that was recently announced to netdev.

In addition flush the disk cache on fsync if the sync cached operation didn't sync the log to disk (this requires some additional bookeping in the transaction and log code). If the device doesn't claim to support barriers, the filesystem has an extern log volume or the trial superblock write with barriers enabled failed we disable barriers and print a warning. We should probably fail the mount completely, but that could lead to nasty boot failures for the root filesystem. Not enabled by default yet, needs more destructive testing first.

Basically, the data/attr forks now grow up/down from either end of the literal area, rather than dividing the literal area into two chunks and growing both upward. Means we can now make much more efficient use of the attribute space, incl. fitting DMF attributes inline in 256 byte inodes, and large jumps in dbench3 performance numbers. It is self enabling, but can be forced on/off via the attr2/noattr2 mount options.

The old ppc32 version did not implement the futex_atomic_op_inuser() callback (it always returned -ENOSYS), so FUTEX_WAKE_OP would not work on ppc32. In fact the ppc64 version of this function is almost suitable for ppc32 as well - the only change needed is to extend ppc_asm.h with a macro expanding to to the right pseudo-op to store a pointer (either ".long" or ".llong").

Therefore, this patch moves naca.h from include/asm-ppc64 to arch/powerpc/platforms/iseries. There was one file including naca.h outside of platforms/iseries - arch/ppc64/kernel/udbg_scc.c. However, that's obviously a hangover from older days. The include is not necessary, so this patch simply removes it. Built and booted on iSeries, built for G5 (which uses udbg_scc.o).

Further explanation by David Stevens: Multicast source filters aren't widely used yet, and that's really the only feature that's affected if an application actually exercises this bug, as far as I can tell. An ordinary filter-less multicast join should still work, and only forwarded multicast traffic making use of filters and doing empty-source filters with the MSFILTER ioctl would be at risk of not getting multicast traffic forwarded to them because the reports generated would not be based on the correct counts.

Original code was based on BIC 1.0 and the default there was 32. Later code (2.6.13) included compensation for delayed acks, and should have reduced the default value to 16; since normally TCP gets one ack for every two packets sent.

It works only when the XFS filesystem support is compiled into the kernel. Menuconfig prevents from setting CONFIG_XFS_FS=m and CONFIG_XFS_QUOTA=y. How to reproduce: configure the XFS filesystem with quota support as module. The resulting kernel won't have quota support compiled into xfs.ko.

Date: Tue, 1 Nov 2005 15:13:02 +0100 Subject: [PKT_SCHED]: Rework QoS and/or fair queueing configuration Make "QoS and/or fair queueing" have its own menu, it's too big to be inlined into "Network options". Remove the obsolete NET_QOS option. Automatically select NET_CLS if needed. Do the same for NET_ESTIMATOR but allow it to be selected manually for statistical purposes. Add comments to separate queueing from classification. Fix dependencies and ordering of classifiers. Improve descriptions/help texts and remove outdated pieces.

But we've already got in the linker script, so we can just use KERNELBASE directly. That means if we ever change KERNELBASE there's one less place to change it.

We can then define register_vpa() and unregister_vpa() which are both simple wrappers around vpa_call(). (we'll need unregister_vpa() for kexec soon) We can then cleanup vpa_init(), and because vpa_init() is only called from platforms/pseries we remove the definition in asm-ppc64/smp.h.

But it's not _quite_ right. The first problem is we calculate the number of registers with: nregs = sizeof(struct pt_regs) / sizeof(ELF_GREG_TYPE) For a 32-bit process on a 64-bit kernel that's bogus because the registers are 64 bits, but ELF_GREG_TYPE is u32, so nregs == 88 which is wrong. The other problem is the memset, which assumes a struct pt_regs is smaller than a struct elf_regs. For a 32-bit process on a 64-bit kernel that's false. The fix is to calculate the number of regs using sizeof(unsigned long), which should always be right, and just memset the whole damn thing _before_ copying the registers in.

Here the via8233_pcm_pointer_hw() function (named snd_via8233_pcm_pointer() before) needed to loop until a non zero position is red from the chip. Measurements have shown that more than 200 loops are typically needed on an Athlon64. As io-reads cost many cycles, those loops sum up huge. via8233_pcm_pointer_hw() runs either in interrupt or with interrupts disabled. So it introduces significant interrupt latency. The patch introduces a calculated position value hwptr_done, that is updated by the interrupt routine when a period is completed. It is only used, if the 823x chip returns a zero position, which can't be interpreted reliably. Further optimisation is applied on the 8233 chip's interrupt routine: Only the SGD_SHADOW is read, as it contains all infos needed. We ommit ~5 more register reads that way.

I have isolated this to the writes to the control port register at offset 0x6cc which were not already protected by the existing reset_workaround. I tried grouping these writes with the existing reset_workaround clause, but that caused the driver to have (un)load problems on the Dell Latitude LS laptops.

This results in an underrun when there isn't enough PCM data available at this point for all URBs. To avoid this, we begin submitting our URBs earlier (when the stream is prepared), with empy packets. When the stream is started, the prepare_playback_urb() call for each URB will be run only when the respective URB has completed previously, so the first hwptr_done updates will be done nicely staggered.

Previously there was a patch to remove this (although the original stuff was broken). Well, now the error bits are needed again. These are used extensively by the micro-engine drivers according to Deepak and also we will need it for the new EDAC code that Alan Cox is trying to push into the main kernel. Re-submit of 3072/1, generated against git tree pulled today. AFAICT, this git tree pulled in all the ARM changes that's in arm.diff. Please let me know if there are additional changes. Thx!

Unfortunately lib/lib.a is listed _before_ arch/arm/lib/lib.a in the link argument list and therefore the architecture specific lib functions are not picked up before the generic versions.

Such requests can arrive in the rescan, flush, and shutdown pathways. The patch also makes the scsi_disk keep a reference to the underlying scsi_device, and it erases the scsi_device's pointer to the scsi_disk when the scsi_device is removed (since the pointer should no longer be used).

Previously 2 buffer-mode was compilation option. Now with this patch applied one can load driver in 2 buffer-mode with module-load parameter ie. #insmod s2io.ko rx_ring_mode=2 This patch also provides 3 buffer-mode which provides header separation functionality. In 3 buffer-mode skb->data will have L2/L3/L4 headers and "skb_shinfo(skb)->frag_list->data" will have have L4 payload. one can load driver in 3 buffer-mode with same above module-load parameter ie. #insmod s2io.ko rx_ring_mode=3 Please review the patch.

This field indicates each phy address to be ignored when probing the mdio bus. This support is needed for the fs_enet and ibm_emac drivers to be converted to the generic phy layer among other drivers. Many systems lock up on probing certain phy addresses or probing doesn't return 0xffff when nothing is found at the address. A new driver I'm working on also makes use of this mask.

Converts the conditions of the form (wred && rio) to (wred) since wred can only be enabled in rio mode anyway. The patch also improves WRED mode detection. The current behaviour does not allow WRED mode to be turned off again without removing the whole qdisc first. The new algorithm checks each VQ against each other looking for equal priorities every time a VQ is changed or added. The performance is poor, O(n**2), but it's used only during administrative tasks and the number of VQs is strictly limited.

This _may_ help to avoid global synchronisation during small bursts of peers advertising but not caring about ECN. Use this option very carefully, it does more harm than good if (qth_max - qth_min) does not cover at least two average burst cycles. The difference to the current behaviour, in which we'd run into the hard queue limit, is that due to the low pass filter of RED short bursts are less likely to cause a global synchronisation.

When newt for instance asks to hide the cursor for better visual aspect, the kernel puts the vga cursor out of the screen, so that the cursor position can't be read by the hardware device. This is a great loss for such people. Here is a patch which uses the same technique as CUR_NONE for hiding the cursor while still moving it. Mario, you should apply it to the speakup kernel for access floppies asap. I'll submit a 2.4 patch too.

The problem is that a process switch return causes tss->io_bitmap_base to be set to IO_BITMAP_OFFSET so that the fault (that *really* sets the io bitmap) never triggers. This fixes that regression.

This eliminates some occasional extra interrupts when a older status tag is written even though all work has been processed. The idea is to read the status tag just before exiting bnx2_poll() and then check again for any new work. If no new work is pending, the status tag written back will not generate any extra interrupt.

This ensures that we have the kernel configuration included from the start, rather than relying on each file having #include as appropriate. History has shown that this is something which is difficult to get right. Since we now include the kernel configuration automatically, make configcheck becomes meaningless, so remove it.

AHB/PCI endianness fix MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Patch from Alessandro Zummo This patch fixes AHB/PCI endianness problems when the processor is in little-endian mode. The patch configures the CSR register closely following the directives in [1], paragraph 4.1, page 19. According to the considerations in [1], page 11, while the AHB bus supports both endian modes, on the IXP4XX it always uses big-endian. The PCI bus is connected to the South AHB. A wrong setting in the CSR register will thus cause a malfunctional PCI bus. A schematic diagram of the bus interconnections on the IXP4XX can be found in [1], page 18. The patch has been verified to work on the NSLU2 in both LE and BE modes. The author is Peter Korsgaard.

This is somewhat ugly to use the same field for different reasons. Introduce distinct field f->target for this purpose. Note, f->fragtree, f->dents, f->target may probably be put in a union.

For the initial scan of the host, we manually scan this bus since it does not obey SAM in regards to sparse LUNs and the disk array devices do not have a consistent product id to use scsi core's blacklist. If /proc/scsi/scsi or sysfs is used to delete one of these devices, the device will not be able to get added back by rescanning the host since scsi core will see ipr's max_channel as 4, rather than 255. Update max_channel after the initial scan so that ipr raid arrays can get re-added if they get deleted.

The queueing model is the NACA queueing model, but it does not mean use of NACA is required. The new model removes some of the adapter firmware queue state that made handling QERR=0 almost impossible. The queueing model on older adapters included the concept of a queue frozen state, which would freeze the response queue in the adapter when a check condition occurred, requiring a a primitive to resume the queue.

The +normal protocol is a four step process. First the device is told +to abort the command. If that doesn't work, the device is reset. +If that doesn't work, the SCSI bus is reset. If that doesn't work +the host bus adapter is reset. Because the cciss driver is a block +driver as well as a SCSI driver and only the tape drives and medium +changers are presented to the SCSI mid layer, and unlike more +straightforward SCSI drivers, disk i/o continues through the block +side during the SCSI error recovery process, the cciss driver only +implements the first two of these actions, aborting the command, and +resetting the device. Additionally, most tape drives will not oblige +in aborting commands, and sometimes it appears they will not even +obey a reset coommand, though in most circumstances they will. In +the case that the command cannot be aborted and the device cannot be +reset, the device will be set offline. + +In the event the error handling code is triggered and a tape drive is +successfully reset or the tardy command is successfully aborted, the +tape drive may still not allow i/o to continue until some command +is issued which positions the tape to a known position. Typically you +must rewind the tape (by issuing "mt -f /dev/st0 rewind" for example) +before i/o can proceed again to a tape drive which was reset. + diff --git a/drivers/block/cciss.c b/drivers/block/cciss.c index 486b6e1..4827860 100644 --- a/drivers/block/cciss.c +++ b/drivers/block/cciss.c @@ -148,6 +148,7 @@ static struct board_type products[] = { static ctlr_info_t *hba[MAX_CTLR]; static void do_cciss_request(request_queue_t *q); +static irqreturn_t do_cciss_intr(int irq, void *dev_id, struct pt_regs *regs); static int cciss_open(struct inode *inode, struct file *filep); static int cciss_release(struct inode *inode, struct file *filep); static int cciss_ioctl(struct inode *inode, struct file *filep, @@ -1586,6 +1587,24 @@ static int fill_cmd(CommandList_struct *c, __u8 cmd, int ctlr, void *buff, } } else if (cmd_type == TYPE_MSG) { switch (cmd) { + case 0: /* ABORT message */ + c->Request.CDBLen = 12; + c->Request.Type.Attribute = ATTR_SIMPLE; + c->Request.Type.Direction = XFER_WRITE; + c->Request.Timeout = 0; + c->Request.CDB[0] = cmd; /* abort */ + c->Request.CDB[1] = 0; /* abort a command */ + /* buff contains the tag of the command to abort */ + memcpy(&c->Request.CDB[4], buff, 8); + break; + case 1: /* RESET message */ + c->Request.CDBLen = 12; + c->Request.Type.Attribute = ATTR_SIMPLE; + c->Request.Type.Direction = XFER_WRITE; + c->Request.Timeout = 0; + memset(&c->Request.CDB[0], 0, sizeof(c->Request.CDB)); + c->Request.CDB[0] = cmd; /* reset */ + c->Request.CDB[1] = 0x04; /* reset a LUN */ case 3: /* No-Op message */ c->Request.CDBLen = 1; c->Request.Type.Attribute = ATTR_SIMPLE; @@ -1872,6 +1891,52 @@ static unsigned long pollcomplete(int ctlr) /* Invalid address to tell caller we ran out of time */ return 1; } + +static int add_sendcmd_reject(__u8 cmd, int ctlr, unsigned long complete) +{ + /* We get in here if sendcmd() is polling for completions + and gets some command back that it wasn't expecting -- + something other than that which it just sent down. + Ordinarily, that shouldn't happen, but it can happen when + the scsi tape stuff gets into error handling mode, and + starts using sendcmd() to try to abort commands and + reset tape drives.

Erase block summary (EBS) stores summary information at the end of every (closed) erase block. It is no longer necessary to scan all nodes separetly (and read all pages of them) just read this "small" summary, where every information is stored which is needed at mount time. This summary information is stored in a JFFS2_FEATURE_RWCOMPAT_DELETE. During the mount process if there is no summary info the orignal scan process will be executed. EBS works with NAND and NOR flashes, too. There is a user space tool called sumtool to generate this summary information for a JFFS2 image.

The resulting kernel still boots on any hardware. On current machines with 4K pages support only, the kernel will maintain 16 "subpages" for each 64K page transparently. Note that while real 64K capable HW has been tested, the current patch will not enable it yet as such hardware is not released yet, and I'm still verifying with the firmware architects the proper to get the information from the newer hypervisors.

First, in the hash setup code, one of the bits allows the size of the hash table to be reduced by a factor of 8 - which would be better accomplished with a command line option for that purpose. The other was a bunch of bus walking related messages in the iSeries code, which would seem to be insufficient reason to keep the mechanism. This patch removes the last traces of this mechanism.

It turned out that this was because of a race in the timeout handling do_write_buffer(). A small timeout of (HZ / 1000) + 1 is used there, and sometimes if the timer interrupt handling takes more than one or even two jiffies (which is 1-2 ms with HZ == 1000) and that interrupt happens just after chip_ready() call, the driver bails out from a ready polling loop despite the chip has actually become ready while all those interrupts were handled.

The patch fixes a bug in the SLB miss handler for hugepages on ppc64 introduced by the dynamic hugepage patch (commit id c594adad5653491813959277fb87a2fef54c4e05) due to a misunderstanding of the srd instruction's behaviour (mea culpa). The problem arises when a 64-bit process maps some hugepages in the low 4GB of the address space (unusual). In this case, as well as the 256M segment in question being marked for hugepages, other segments at 32G intervals will be incorrectly marked for hugepages. In the process, this patch tweaks the semantics of the hugepage bitmaps to be more sensible. Previously, an address below 4G was marked for hugepages if the appropriate segment bit in the "low areas" bitmask was set *or* if the low bit in the "high areas" bitmap was set (which would mark all addresses below 1TB for hugepage). With this patch, any given address is governed by a single bitmap. Addresses below 4GB are marked for hugepage if and only if their bit is set in the "low areas" bitmap (256M granularity). Addresses between 4GB and 1TB are marked for hugepage iff the low bit in the "high areas" bitmap is set. Higher addresses are marked for hugepage iff their bit in the "high areas" bitmap is set (1TB granularity). To avoid conflicts, this patch must be applied on top of BenH's pending patch for 64k base page size [0]. As such, this patch also addresses a hugepage problem introduced by that patch. That patch allows hugepages of 1MB in size on hardware which supports it, however, that won't work when using 4k pages (4 level pagetable), because in that case hugepage PTEs are stored at the PMD level, and each PMD entry maps 2MB. This patch simply disallows hugepages in that case (we can do something cleverer to re-enable them some other day). Built, booted, and a handful of hugepage related tests passed on POWER5 LPAR (both ARCH=powerpc and ARCH=ppc64).

Some platforms (like SH4-202) implement the VCR in a split VCRL and VCRH, but end up being in reverse order or have other quirks that need to be dealt with, so we add a set of superhyway_ops per-bus to accomodate this. We also have to extend the per-device resources somewhat, as some devices now conveniently split control and data blocks. So we allow a platform to register its set of SuperHyway devices via superhyway_add_devices() with the control block always ordered as the first resource (as this is the one that userspace cares about).

If we bump up the P1 offset, it's possible to hit a shadowed region of memory where we suddenly become magically contiguous. As people have been using this shadowed region workaround for quite some time (and without any adverse effects), it's time to drop the left over discontig bits that no longer have any practical use (it was always very much hp690-centric to begin with).

As a result, BIOS ends up bombarded with interrupts early on boot. The BIOS does not expect it since following a "normal" hardware cpu reset, all APIC LVT registers have the Mask bit (16) set and can't generate interrupts. For example, the version of Phoenix BIOS used by VMware enables interrupts for the first time before masking/clearing APIC LVT. The APIC Timer LVT register is still set up for a timer interrupt delivery with a high vector from the previous Linux incarnation (0xef in our case). The BIOS has not fully initialized its IDT at this point and the real mode gate for 0xef remains all zeros. Vector 0xef dispatches BIOS to address 0:0, BIOS takes a #GP and eventually hangs. machine_shutdown() does attempt to shut down APIC before jumping to BIOS, but it is ineffective" Signed-off-by: Zwane Mwaikambo Cc: "Seth, Rohit" Cc: Zachary Amsden Cc: "Eric W.

All the traces start at the last notifier_call_chain(...) in kernel/cpu.c. Since we hold the cpu_control semaphore it shouldn't be any problem to access cpu_online_map. The reason why cpu_up failed is simply that the cpu that was supposed to be taken online wasn't even there. That is because on s390 we never know when a new cpu comes and therefore cpu_possible_map consists of only ones and doesn't reflect reality.

So I fixed the thing by rewriting the __asm__ constraints more like unistd.h ones. Note: in syscall6 case I had to add one more instruction (i.e. moving arg6 in eax and shuffling things around) - it's needed for the function to be valid in general (we can't load the value from the stack, relative to ebp, because we change it), but could be avoided since we actually use a constant as param 6. The only fix would be to turn stub_syscall6 to a macro and use a "i" constraint for arg6 (i.e., specify it's a constant value).

It does not work together with the system call speedup that makes the complete system call path enabled for interrupts. To make pagex and the syscall speedup code work together we would have to add code to the program check handler to do a critical section cleanup like the asynchronous interrupt code. This would make program checks slower. Not what we want. Newer versions of z/VM have the improved pfault pseudo page fault interface. This replaces the old pagex interface and does not have the problem. So its better to just rip out the pagex code.

This let innocent tasks get their new limit tested along with a racing guilty task that was crossing the limit. This serializes the _nr accounting with a spinlock It also switches to using unsigned long for the global totals. Individual contexts are still limited to an unsigned int's worth of requests by the syscall interface. The problem and fix were verified with a simple program that spun creating and destroying a context while holding on to another long lived context. Before the patch a task creating a tiny context could get a spurious EAGAIN if it raced with a task creating a very large context that overran the limit.

That callback can return an error code, but currently the caller assumes any error is EFAULT, and will try various things to resolve the fault before eventually giving up with EFAULT (regardless of the original error code). This is not a theoretical case - arch callbacks currently return -ENOSYS if the opcode they are given is bogus. This patch alters the code to detect non-EFAULT errors and return them directly to the user.

This patch moves it to kernel/ptrace.c and leaves the arch-specific code as arch_ptrace. Some architectures have a too different ptrace so we have to exclude them. They continue to keep their implementations. For sh64 I had to add a sh64_ptrace wrapper because it does some initialization on the first call.

Help and analysis from Seetharami Seelam Performance testing from Seelam: I set up my system and executed a couple of tests that I used for OLS. I tested with AS, cooperative process patch merged in -mm tree (which I called Nick, below) and the cooperative patch with modifications to as_update_iohist (which I called Seelam). I used a dual-processor (2.28GHz Pentium 4 Xeon) system, with 1 GB main memory and 1 MB L2 cache, running Linux 2.6.9. Only a single processor is used for the experiments. I used 7.2K RPM Maxtor 10GB drive configured with ext2 file system. Experiment 1 (ex1) consists of reading one Linux source trees using find . -type f -exec cat '{}' ';' > /dev/null. Experiment 2 (ex2) consists of reading two disjoint Linux source trees using find . -type f -exec cat '{}' ';' > /dev/null. Experiment 3 (ex3) consists of streaming read of a 2GB file in the background and 1 instance of the chunk reads in Experiment 1. Timings for reading the Linux source are shown below: AS Nick Seelam ex1: 0m25.813s 0m27.859s 0m27.640s ex2: 1m11.468s 1m13.918s 1m5.869s ex3: 81m44.352s 10m38.572s 6m47.994s The difference between the numbers in Experiment 3 must be due to the code in as_update_iohist. (akpm: that's not part of this patch. So this patch is "Nick").

This has been out and tested for a while in the latest IPMI driver release. There are no functional changes, just changes as necessary to convert the locking over (and a few minor style updates). The IPMI driver uses read/write locks to ensure that things exist while they are in use. This is bad from a number of points of view. This patch removes the rwlocks and uses refcounts and RCU lists to manage what the locks did.

Clear B2H_ATN and drain the BMC message buffer on command timeout. This prevents further commands from failing after a timeout. Add bt_debug and smic_debug module parameters, expose them in sysfs. This lets you enable and disable debugging messages at runtime. Unsigned jiffies math in ipmi_si_intf.c causes a too-large value to be passed to ->event() after jiffies wrap-around. The BT driver had caught this, but didn't know how to fix it. Now all calls to ->event() use a sane value for time. Increase timeout for commands handed to the BT driver from 2 seconds to 5 seconds. This is necessary particularly when the previous command was a "Clear SEL", as that command completes, yet the BMC isn't really ready to handle another command yet. Silence BT debugging messages which were being printed on the console. Increase SMIC timeout form 1/10s to 2s. This is needed on Dell PowerEdge 2650 and PowerEdge 750 with ERA/O cards to allow commands to complete without timing out. Adds kcs_debug module param, to match behavior of BT and SMIC. This also prevents messages from being sent to the console unless explicitly requested.

If this occurs, no further commands will ever succeed unless the state of the controller is first cleared out. Furthermore, the soft reset would only occur if the first command after insmod was the one that timed out, not if a later command timed out. This patch changes the retry/reset mechanism to be as follows: Before retrying a command, clear the state of the BT controller such that the flags represent ready for a new transaction. This increases the chance of success of the restarted transaction. After 2 retries, issue a soft reset and retry one more time before giving up and reporting back a failure.

In particular, clearing OBF may not take effect immediately. We want it to delay in ERROR0 after clearing OBF a bit waiting for OBF to actually be clear before proceeding. This introduces a new return value from the LLDD's event loop, SI_SM_CALL_WITH_TICK_DELAY. This means the calling thread/timer should schedule_timeout() at least 1 tick, rather than busy-wait. This is a longer delay than SI_SM_CALL_WITH_DELAY, which is typically a 250us busy-wait.

The default poll interval is based on using a kernel timer, which varies with HZ. For character-based interfaces like KCS and SMIC though, that can be way too slow (>15 minutes to flash a new firmware with KCS, >20 seconds to retrieve the sensor list). This creates a low-priority kernel thread to poll more often. If the state machine is idle, so is the kernel thread. But if there's an active command, it polls quite rapidly. This decrease a firmware flash time from 15 minutes to 1.5 minutes, and the sensor list time to 4.5 seconds, on a Dell PowerEdge x8x system. The timer-based polling remains, to ensure some amount of responsiveness even under high user process CPU load. Checking for a stopped timer at rmmod now uses atomics and del_timer_sync() to ensure safe stoppage.

We currently serialize kprobe registration, unregistration and handler execution using a single spinlock - kprobe_lock. With these changes, kprobe handlers can run without any locks held. It also allows for simultaneous kprobe handler executions on different processors as we now track kprobe execution on a per processor basis. It is now necessary that the handlers be re-entrant since handlers can run concurrently on multiple processors. All changes have been tested on i386, ia64, ppc64 and x86_64, while sparc64 has been compile tested only. The patches can be viewed as 3 logical chunks: patch 1: Reorder preempt_(dis/en)able calls patches 2-7: Introduce per_cpu data areas to track kprobe execution patches 8-9: Use RCU to synchronize kprobe (un)registration and handler execution. Thanks to Maneesh Soni, James Keniston and Anil Keshavamurthy for their review and suggestions. Thanks again to Anil, Hien Nguyen and Kevin Stafford for testing the patches. This patch: Reorder preempt_disable/enable() calls in arch kprobes files in preparation to introduce locking changes. No functional changes introduced by this patch.

RIO is a switched fabric interconnect used in higher-end embedded applications. The curious can look at the specs over at http://www.rapidio.org The core code implements enumeration/discovery, management of devices/resources, and interfaces for RIO drivers. There's a lot more to do to take advantages of all the hardware features. However, this should provide a good base for folks with RIO hardware to start contributing.

This adds a driver option to force it, and by default "reads" the current value from the chip to get the firmware setting. It significantly improves the quality of images on the iMac G5 I have here (though the X driver doesn't yet "read" the current value and defaults to 0, so you have to add Option "FBDither" "true" to your X config file to get that, I'll try to fix X.org to "read" the default unless specified asap).

Daplas" Date: Mon, 7 Nov 2005 01:00:35 -0800 Subject: [PATCH] fbcon/fbdev: Move softcursor out of fbdev to fbcon According to Jon Smirl, filling in the field fb_cursor with soft_cursor for drivers that do not support hardware cursors is redundant. The soft_cursor function is usable by all drivers because it is just a wrapper around fb_imageblit. And because soft_cursor is an fbcon-specific hook, the file is moved to the console directory. Thus, drivers that do not support hardware cursors can leave the fb_cursor field blank. For drivers that do, they can fill up this field with their own version. The end result is a smaller code size. And if the framebuffer console is not loaded, module/kernel size is also reduced because the soft_cursor module will also not be loaded.

In both case, the screen stays black, but seems divided into 4 vertical bands. Some white lines pop up randomly on each vertical band." The problem is a combination of an incorrect xclk plus lack of timing information. The adapter is attached to an LCD device that can do 1280x600 (which is not a standard resolution). The global mode database does not have an entry for it. Fortunately, the Video BIOS contains the complete timing info for this display, however, atyfb is not making use of it. Add support to get the timing information from the BIOS, if available.

This patch fixes the function so that it looks for the closest mode as far as both resolution and refresh rate are concerned. The function's first argument is changed to fb_videomode so that the refresh rate can be specified by the caller, as fb_var_screeninfo doesn't have any fields that could directly hold this data.

Issues related to race with rename are +handled as described below : + +1. Look-up can be done in two ways - d_lookup() which is safe from + simultaneous renames and __d_lookup() which is not.

To avoid memcmp() in + __d_lookup() go out of bounds due to a rename and false positive + comparison, the name comparison is done while holding the + per-dentry lock. This prevents concurrent renames during this + operation. + +3.

Pages of data read from +backing store (usually the block device the filesystem is mounted on) are kept +around in case it's needed again, but marked as clean (freeable) in case the +Virtual Memory system needs the memory for something else. Similarly, data +written to files is marked clean as soon as it has been written to backing +store, but kept around for caching purposes until the VM reallocates the +memory. A similar mechanism (the dentry cache) greatly speeds up access to +directories. + +With ramfs, there is no backing store. Files written into ramfs allocate +dentries and page cache as usual, but there's nowhere to write them to. +This means the pages are never marked clean, so they can't be freed by the +VM when it's looking to recycle memory. + +The amount of code required to implement ramfs is tiny, because all the +work is done by the existing Linux caching infrastructure. Basically, +you're mounting the disk cache as a filesystem. Because of this, ramfs is not +an optional component removable via menuconfig, since there would be negligible +space savings. + +ramfs and ramdisk: +------------------ + +The older "ram disk" mechanism created a synthetic block device out of +an area of ram and used it as backing store for a filesystem. This block +device was of fixed size, so the filesystem mounted on it was of fixed +size. Using a ram disk also required unnecessarily copying memory from the +fake block device into the page cache (and copying changes back out), as well +as creating and destroying dentries. Plus it needed a filesystem driver +(such as ext2) to format and interpret this data. + +Compared to ramfs, this wastes memory (and memory bus bandwidth), creates +unnecessary work for the CPU, and pollutes the CPU caches. (There are tricks +to avoid this copying by playing with the page tables, but they're unpleasantly +complicated and turn out to be about as expensive as the copying anyway.) +More to the point, all the work ramfs is doing has to happen _anyway_, +since all file access goes through the page and dentry caches. The ram +disk is simply unnecessary, ramfs is internally much simpler. + +Another reason ramdisks are semi-obsolete is that the introduction of +loopback devices offered a more flexible and convenient way to create +synthetic block devices, now from files instead of from chunks of memory. +See losetup (8) for details. + +ramfs and tmpfs: +---------------- + +One downside of ramfs is you can keep writing data into it until you fill +up all memory, and the VM can't free it because the VM thinks that files +should get written to backing store (rather than swap space), but ramfs hasn't +got any backing store. Because of this, only root (or a trusted user) should +be allowed write access to a ramfs mount. + +A ramfs derivative called tmpfs was created to add size limits, and the ability +to write the data to swap space. Normal users can be allowed write access to +tmpfs mounts. See Documentation/filesystems/tmpfs.txt for more information. + +What is rootfs? +--------------- + +Rootfs is a special instance of ramfs, which is always present in 2.6 systems. +(It's used internally as the starting and stopping point for searches of the +kernel's doubly-linked list of mount points.) + +Most systems just mount another filesystem over it and ignore it. The +amount of space an empty instance of ramfs takes up is tiny. + +What is initramfs? +------------------ + +All 2.6 Linux kernels contain a gzipped "cpio" format archive, which is +extracted into rootfs when the kernel boots up. After extracting, the kernel +checks to see if rootfs contains a file "init", and if so it executes it as PID +1. If found, this init process is responsible for bringing the system the +rest of the way up, including locating and mounting the real root device (if +any). If rootfs does not contain an init program after the embedded cpio +archive is extracted into it, the kernel will fall through to the older code +to locate and mount a root partition, then exec some variant of /sbin/init +out of that. + +All this differs from the old initrd in several ways: + + - The old initrd was a separate file, while the initramfs archive is linked + into the linux kernel image. (The directory linux-*/usr is devoted to + generating this archive during the build.) + + - The old initrd file was a gzipped filesystem image (in some file format, + such as ext2, that had to be built into the kernel), while the new + initramfs archive is a gzipped cpio archive (like tar only simpler, + see cpio(1) and Documentation/early-userspace/buffer-format.txt). + + - The program run by the old initrd (which was called /initrd, not /init) did + some setup and then returned to the kernel, while the init program from + initramfs is not expected to return to the kernel. (If /init needs to hand + off control it can overmount / with a new root device and exec another init + program. See the switch_root utility, below.) + + - When switching another root device, initrd would pivot_root and then + umount the ramdisk. But initramfs is rootfs: you can neither pivot_root + rootfs, nor unmount it. Instead delete everything out of rootfs to + free up the space (find -xdev / -exec rm '{}' ';'), overmount rootfs + with the new root (cd /newmount; mount --move . /; chroot .), attach + stdin/stdout/stderr to the new /dev/console, and exec the new init. + + Since this is a remarkably persnickity process (and involves deleting + commands before you can run them), the klibc package introduced a helper + program (utils/run_init.c) to do all this for you. Most other packages + (such as busybox) have named this command "switch_root". + +Populating initramfs: +--------------------- + +The 2.6 kernel build process always creates a gzipped cpio format initramfs +archive and links it into the resulting kernel binary. By default, this +archive is empty (consuming 134 bytes on x86). The config option +CONFIG_INITRAMFS_SOURCE (for some reason buried under devices->block devices +in menuconfig, and living in usr/Kconfig) can be used to specify a source for +the initramfs archive, which will automatically be incorporated into the +resulting binary. This option can point to an existing gzipped cpio archive, a +directory containing files to be archived, or a text file specification such +as the following example: + + dir /dev 755 0 0 + nod /dev/console 644 0 0 c 5 1 + nod /dev/loop0 644 0 0 b 7 0 + dir /bin 755 1000 1000 + slink /bin/sh busybox 777 0 0 + file /bin/busybox initramfs/busybox 755 0 0 + dir /proc 755 0 0 + dir /sys 755 0 0 + dir /mnt 755 0 0 + file /init initramfs/init.sh 755 0 0 + +One advantage of the text file is that root access is not required to +set permissions or create device nodes in the new archive. (Note that those +two example "file" entries expect to find files named "init.sh" and "busybox" in +a directory called "initramfs", under the linux-2.6.* directory. See +Documentation/early-userspace/README for more details.) + +If you don't already understand what shared libraries, devices, and paths +you need to get a minimal root filesystem up and running, here are some +references: +http://www.tldp.org/HOWTO/Bootdisk-HOWTO/ +http://www.tldp.org/HOWTO/From-PowerUp-To-Bash-Prompt-HOWTO.html +http://www.linuxfromscratch.org/lfs/view/stable/ + +The "klibc" package (http://www.kernel.org/pub/linux/libs/klibc) is +designed to be a tiny C library to statically link early userspace +code against, along with some related utilities. It is BSD licensed. + +I use uClibc (http://www.uclibc.org) and busybox (http://www.busybox.net) +myself. These are LGPL and GPL, respectively. + +In theory you could use glibc, but that's not well suited for small embedded +uses like this. (A "hello world" program statically linked against glibc is +over 400k. With uClibc it's 7k. Also note that glibc dlopens libnss to do +name lookups, even when otherwise statically linked.) + +Future directions: +------------------ + +Today (2.6.14), initramfs is always compiled in, but not always used. The +kernel falls back to legacy boot code that is reached only if initramfs does +not contain an /init program. The fallback is legacy code, there to ensure a +smooth transition and allowing early boot functionality to gradually move to +"early userspace" (I.E. initramfs). + +The move to early userspace is necessary because finding and mounting the real +root device is complex. Root partitions can span multiple devices (raid or +separate journal). They can be out on the network (requiring dhcp, setting a +specific mac address, logging into a server, etc). They can live on removable +media, with dynamically allocated major/minor numbers and persistent naming +issues requiring a full udev implementation to sort out. They can be +compressed, encrypted, copy-on-write, loopback mounted, strangely partitioned, +and so on. + +This kind of complexity (which inevitably includes policy) is rightly handled +in userspace. Both klibc and busybox/uClibc are working on simple initramfs +packages to drop into a kernel build, and when standard solutions are ready +and widely deployed, the kernel's legacy early boot code will become obsolete +and a candidate for the feature removal schedule. + +But that's a while off yet. -- cgit v0.10.2 From d44e0780bcc47c9b8851099c0dfc1dda3c9db5a9 Mon Sep 17 00:00:00 2001 From: Randy Dunlap Date: Mon, 7 Nov 2005 01:01:10 -0800 Subject: [PATCH] kernel-doc: fix warnings in vmalloc.c Fix new kernel-doc errors in vmalloc.c.

Most it does is the #if 0 of EXPORT_SYMBOL's, so if any modular code will use any of them, re-adding will be trivial. Modular ISAPnP might be interesting in some cases, but this is more legacy code. If someone would work on it to sort all the issues out (starting with the point that most users of __ISAPNP__ will have to be fixed) re-enabling the required EXPORT_SYMBOL's won't be hard for him.

We need multiple notification points for these events because they can take many seconds to run which has nasty effects on the behaviour of the rest of the system. DIE_SS replaced by a generic DIE_FAULT which checks the vector number, to allow interception of faults other than SS. DIE_MACHINE_{HALT,RESTART} added to allow last minute close down processing, especially when the halt/restart routines are called from error handlers. DIE_OOPS added. The check for kprobe's break numbers has been moved from traps.c to kprobes.c, allowing DIE_BREAK to be used for any additional break numbers, i.e. it is no longer kprobes specific. Hooks for kernel debuggers and kernel dumpers added, ENTER and LEAVE. Both of these disable the system for long periods which impact on watchdogs and heartbeat systems in general. More patches to come that use these events to reset watchdogs and heartbeats. unregister_die_notifier() added and both routines exported. Requested by Dean Nelson. Lock removed from {un,}register_die_notifier. notifier_chain_register() already takes a lock. Also the generic notifier chain locking is being reworked to distinguish between callbacks that can block and those that cannot, the lock in {un,}register_die_notifier would interfere with that change. http://marc.theaimsgroup.com/?l=linux-kernel&m=113018709002036&w=2 Leading white space removed from arch/ia64/kernel/kprobes.c.

This seems to be a private affair between switch_mm and activate_mm, using page_table_lock as a per-mm lock, without any relation to its uses elsewhere. That's fine, but comment it as such; and unlock sooner in switch_mm, more like in activate_mm (preemption is disabled here). There is a block of "if (0)"ed code in smp_flush_tlb_pending which would have liked to rely on the page_table_lock, in switch_mm and elsewhere; but its comment explains how dup_mmap's flush_tlb_mm defeated it. And though that could have been changed at any time over the past few years, now the chance vanishes as we push the page_table_lock downwards, and perhaps split it per page table page. Just delete that block of code. Which leaves the mysterious spin_unlock_wait(&oldmm->page_table_lock) in kernel/fork.c copy_mm. Textual analysis (supported by Nick Piggin) suggests that the comment was written by DaveM, and that it relates to the defeated approach in the sparc64 smp_flush_tlb_pending. Just delete this block too. Signed-off-by: Hugh Dickins Signed-off-by: David S.

We now add back in as a supported rate any mandatory rate. Fixed #597 kernel oops due to calling dev_kfree_skb on an skb multiple times. Added code to control LEDs that can be controlled through the wireless NIC (vs. non-wireless HW interfaces) -- this is currently disabled by default due to reports by some users of it hanging their laptop. Added some more debug messages around fragmentation logic Added locking around STATUS_HCMD_ACTIVE to prevent re-entry race conditions Moved ipw_adapter_restart to only execute on the priv->workqueue to keep keyboard errors from occuring during adapter restart Added CFG_BACKGROUND_SCAN to easily allow people to play with background scanning implementations Modified WPA logic to send WPA IE if one is set (vs. being based on wpa_enabled) Modified scan result logic to report WPA and RSN IEs if set (vs. being based on wpa_enabled) Fixed issues with endianess compatability between the host and wireless adapter (thanks to York Liu and Yi Zhu) Fixed problem with Ad-Hoc network creation causing a firmware error if a scan was actively running (thanks to Mohamed Abbas) Signed-off-by: James Ketrenos diff --git a/drivers/net/wireless/ipw2200.c b/drivers/net/wireless/ipw2200.c index ddbee3e..ea7a3dc 100644 --- a/drivers/net/wireless/ipw2200.c +++ b/drivers/net/wireless/ipw2200.c @@ -32,7 +32,7 @@ #include "ipw2200.h" -#define IPW2200_VERSION "1.0.1" +#define IPW2200_VERSION "1.0.2" #define DRV_DESCRIPTION "Intel(R) PRO/Wireless 2200/2915 Network Driver" #define DRV_COPYRIGHT "Copyright(c) 2003-2004 Intel Corporation" #define DRV_VERSION IPW2200_VERSION @@ -49,6 +49,7 @@ static int mode = 0;

This is being actively developed but is the first step in getting WMM support into the driver and the kernel. * Fixed some race conditions with channel changes, association, and scan abort that could periodically cause a firmware restart. * Added some extensions to export scan and network statistics to user space (exposed through speed_scan and net_stats sysfs entries) * Fixed a few bugs in how monitor mode was supported (scan lists weren't quite right) * Updated the firmware requirement from 2.2 to 2.3 which supports monitor mode.

17 00:00:00 2001 From: James Ketrenos Date: Wed, 24 Aug 2005 22:33:31 -0500 Subject: Catch ipw2100 up to equivelancy with v1.1.1 * Added WE-18 support. This allows the use of -Dext with wpa_supplicant > 0.4.x (thanks to Hong Liu) * Fixed #339 problem with iwconfig set/get txpower (thanks to Hong Liu) * Fixed #598 problem when with error messages when module loaded with 'disable=1' (thanks to Hong Liu) * Fixed #640 problem with 'iwlist retry' now showing min/max retry * Fixed compatibility with wpa_supplicant and the new -Dipw interface (that included a fix for 64-bit compatibility) * Added CFG_CRC_CHECK which allows passing through packets with bad CRCs while in monitor mode.

Another channel change comes at this time, then the driver will issue disassociate command to the firmware which will cause the fatal error. It seems that the association/disassociation procedure should not be interrupted.

The proper way to deal with that is to introduce the second kind of reference to vfsmount. Semantics: - when the last normal reference is dropped, all special ones are converted to normal ones and if there had been any, cleanup is done. - normal reference can be cloned into a special one - special reference can be converted to normal one; that's a no-op if we'd already passed the point of no return (i.e. mntput() had converted special references to normal and started cleanup). The way it works: e.g. starting process accounting converts the vfsmount reference pinned by the opened file into special one and turns it back to normal when it gets shut down; acct_auto_close() is done when no normal references are left. That way it does *not* obstruct umount(2) and it silently gets turned off when the last normal reference to vfsmount is gone. Which is exactly what we want... The same should be done by LSM module that holds some internal references to vfsmount and wants to shut them down on umount - it should make them special and security_sb_umount_close() will be called exactly when the last normal reference to vfsmount is gone. quota handling is even simpler - we don't use normal file IO anymore, so there's no need to hold vfsmounts at all. DQUOT_OFF() is done from deactivate_super(), where it really belongs.

Also unbindable mount disallows bind mounts. The semantics is as follows. Bind semantics: It is invalid to bind mount an unbindable mount. Move semantics: It is invalid to move an unbindable mount under shared mount. Clone-namespace semantics: If a mount is unbindable in the parent namespace, the corresponding cloned mount in the child namespace becomes unbindable too. Note: there is subtle difference, unbindable mounts cannot be bind mounted but can be cloned during clone-namespace.

And mark some part + of its namespace as slave + + mount --make-rslave /myprivatetree + + Hence forth any mounts within the /myprivatetree done by the + process will not show up in any other namespace. However mounts + done in the parent namespace under /myprivatetree still shows + up in the process's namespace. + + + Apart from the above semantics this feature provides the + building blocks to solve the following problems: + + C) Per-user namespace + + The above semantics allows a way to share mounts across + namespaces. But namespaces are associated with processes. If + namespaces are made first class objects with user API to + associate/disassociate a namespace with userid, then each user + could have his/her own namespace and tailor it to his/her + requirements. Offcourse its needs support from PAM. + + D) Versioned files + + If the entire mount tree is visible at multiple locations, then + a underlying versioning file system can return different + version of the file depending on the path used to access that + file. + + An example is: + + mount --make-shared / + mount --rbind / /view/v1 + mount --rbind / /view/v2 + mount --rbind / /view/v3 + mount --rbind / /view/v4 + + and if /usr has a versioning filesystem mounted, than that + mount appears at /view/v1/usr, /view/v2/usr, /view/v3/usr and + /view/v4/usr too + + A user can request v3 version of the file /usr/fs/namespace.c + by accessing /view/v3/usr/fs/namespace.c . The underlying + versioning filesystem can then decipher that v3 version of the + filesystem is being requested and return the corresponding + inode. + +5) Detailed semantics: +------------------- + The section below explains the detailed semantics of + bind, rbind, move, mount, umount and clone-namespace operations. + + Note: the word 'vfsmount' and the noun 'mount' have been used + to mean the same thing, throughout this document. + +5a) Mount states + + A given mount can be in one of the following states + 1) shared + 2) slave + 3) shared and slave + 4) private + 5) unbindable + + A 'propagation event' is defined as event generated on a vfsmount + that leads to mount or unmount actions in other vfsmounts. + + A 'peer group' is defined as a group of vfsmounts that propagate + events to each other. + + (1) Shared mounts + + A 'shared mount' is defined as a vfsmount that belongs to a + 'peer group'. + + For example: + mount --make-shared /mnt + mount --bin /mnt /tmp + + The mount at /mnt and that at /tmp are both shared and belong + to the same peer group. Anything mounted or unmounted under + /mnt or /tmp reflect in all the other mounts of its peer + group. + + + (2) Slave mounts + + A 'slave mount' is defined as a vfsmount that receives + propagation events and does not forward propagation events. + + A slave mount as the name implies has a master mount from which + mount/unmount events are received. Events do not propagate from + the slave mount to the master. Only a shared mount can be made + a slave by executing the following command + + mount --make-slave mount + + A shared mount that is made as a slave is no more shared unless + modified to become shared. + + (3) Shared and Slave + + A vfsmount can be both shared as well as slave. This state + indicates that the mount is a slave of some vfsmount, and + has its own peer group too. This vfsmount receives propagation + events from its master vfsmount, and also forwards propagation + events to its 'peer group' and to its slave vfsmounts. + + Strictly speaking, the vfsmount is shared having its own + peer group, and this peer-group is a slave of some other + peer group. + + Only a slave vfsmount can be made as 'shared and slave' by + either executing the following command + mount --make-shared mount + or by moving the slave vfsmount under a shared vfsmount. + + (4) Private mount + + A 'private mount' is defined as vfsmount that does not + receive or forward any propagation events. + + (5) Unbindable mount + + A 'unbindable mount' is defined as vfsmount that does not + receive or forward any propagation events and cannot + be bind mounted. + + + State diagram: + The state diagram below explains the state transition of a mount, + in response to various commands. + ------------------------------------------------------------------------ + | |make-shared | make-slave | make-private |make-unbindab| + --------------|------------|--------------|--------------|-------------| + |shared |shared |*slave/private| private | unbindable | + | | | | | | + |-------------|------------|--------------|--------------|-------------| + |slave |shared | **slave | private | unbindable | + | |and slave | | | | + |-------------|------------|--------------|--------------|-------------| + |shared |shared | slave | private | unbindable | + |and slave |and slave | | | | + |-------------|------------|--------------|--------------|-------------| + |private |shared | **private | private | unbindable | + |-------------|------------|--------------|--------------|-------------| + |unbindable |shared |**unbindable | private | unbindable | + ------------------------------------------------------------------------ + + * if the shared mount is the only mount in its peer group, making it + slave, makes it private automatically.

A new propagation tree is set containing all new mounts + 'C', 'C1', .., 'Cn' with exactly the same configuration as the + propagation tree for 'B'. + + 3.

In other words 'A' and 'C' are both slave mounts of + 'Z'. All mount/unmount events on 'Z' propagates to 'A' and 'C'. But + mount/unmount on 'A' do not propagate anywhere else. Similarly + mount/unmount on 'C' do not propagate anywhere else. + + 8. 'A' is a unbindable mount and 'B' is a non-shared mount. This is a + invalid operation. A unbindable mount cannot be bind mounted. + +5c) Rbind semantics + + rbind is same as bind. Bind replicates the specified mount. Rbind + replicates all the mounts in the tree belonging to the specified mount. + Rbind mount is bind mount applied to all the mounts in the tree. + + If the source tree that is rbind has some unbindable mounts, + then the subtree under the unbindable mount is pruned in the new + location. + + eg: lets say we have the following mount tree. + + A + / \ + B C + / \ / \ + D E F G + + Lets say all the mount except the mount C in the tree are + of a type other than unbindable. + + If this tree is rbound to say Z + + We will have the following tree at the new location. + + Z + | + A' + / + B' Note how the tree under C is pruned + / \ in the new location. + D' E' + + + +5d) Move semantics + + Consider the following command + + mount --move A B/b + + where 'A' is the source mount, 'B' is the destination mount and 'b' is + the dentry in the destination mount. + + The outcome depends on the type of the mount of 'A' and 'B'. The table + below is a quick reference. + --------------------------------------------------------------------------- + | MOVE MOUNT OPERATION | + |************************************************************************** + | source(A)->| shared | private | slave | unbindable | + | dest(B) | | | | | + | | | | | | | + | v | | | | | + |************************************************************************** + | shared | shared | shared |shared and slave| invalid | + | | | | | | + |non-shared| shared | private | slave | unbindable | + *************************************************************************** + NOTE: moving a mount residing under a shared mount is invalid. + + Details follow: + + 1. 'A' is a shared mount and 'B' is a shared mount. The mount 'A' is + mounted on mount 'B' at dentry 'b'. Also new mounts 'A1', 'A2'...'An' + are created and mounted at dentry 'b' on all mounts that receive + propagation from mount 'B'. A new propagation tree is created in the + exact same configuration as that of 'B'. This new propagation tree + contains all the new mounts 'A1', 'A2'... 'An'. And this new + propagation tree is appended to the already existing propagation tree + of 'A'. + + 2. 'A' is a private mount and 'B' is a shared mount. The mount 'A' is + mounted on mount 'B' at dentry 'b'. Also new mount 'A1', 'A2'... 'An' + are created and mounted at dentry 'b' on all mounts that receive + propagation from mount 'B'. The mount 'A' becomes a shared mount and a + propagation tree is created which is identical to that of + 'B'. This new propagation tree contains all the new mounts 'A1', + 'A2'... 'An'. + + 3. 'A' is a slave mount of mount 'Z' and 'B' is a shared mount. The + mount 'A' is mounted on mount 'B' at dentry 'b'. Also new mounts 'A1', + 'A2'... 'An' are created and mounted at dentry 'b' on all mounts that + receive propagation from mount 'B'. A new propagation tree is created + in the exact same configuration as that of 'B'. This new propagation + tree contains all the new mounts 'A1', 'A2'... 'An'. And this new + propagation tree is appended to the already existing propagation tree of + 'A'. Mount 'A' continues to be the slave mount of 'Z' but it also + becomes 'shared'. + + 4. 'A' is a unbindable mount and 'B' is a shared mount. The operation + is invalid. Because mounting anything on the shared mount 'B' can + create new mounts that get mounted on the mounts that receive + propagation from 'B'. And since the mount 'A' is unbindable, cloning + it to mount at other mountpoints is not possible. + + 5. 'A' is a private mount and 'B' is a non-shared(private or slave or + unbindable) mount. The mount 'A' is mounted on mount 'B' at dentry 'b'. + + 6. 'A' is a shared mount and 'B' is a non-shared mount. The mount 'A' + is mounted on mount 'B' at dentry 'b'. Mount 'A' continues to be a + shared mount. + + 7. 'A' is a slave mount of mount 'Z' and 'B' is a non-shared mount. + The mount 'A' is mounted on mount 'B' at dentry 'b'. Mount 'A' + continues to be a slave mount of mount 'Z'. + + 8. 'A' is a unbindable mount and 'B' is a non-shared mount. The mount + 'A' is mounted on mount 'B' at dentry 'b'. Mount 'A' continues to be a + unbindable mount. + +5e) Mount semantics + + Consider the following command + + mount device B/b + + 'B' is the destination mount and 'b' is the dentry in the destination + mount. + + The above operation is the same as bind operation with the exception + that the source mount is always a private mount. + + +5f) Unmount semantics + + Consider the following command + + umount A + + where 'A' is a mount mounted on mount 'B' at dentry 'b'. + + If mount 'B' is shared, then all most-recently-mounted mounts at dentry + 'b' on mounts that receive propagation from mount 'B' and does not have + sub-mounts within them are unmounted. + + Example: Lets say 'B1', 'B2', 'B3' are shared mounts that propagate to + each other. + + lets say 'A1', 'A2', 'A3' are first mounted at dentry 'b' on mount + 'B1', 'B2' and 'B3' respectively. + + lets say 'C1', 'C2', 'C3' are next mounted at the same dentry 'b' on + mount 'B1', 'B2' and 'B3' respectively. + + if 'C1' is unmounted, all the mounts that are most-recently-mounted on + 'B1' and on the mounts that 'B1' propagates-to are unmounted. + + 'B1' propagates to 'B2' and 'B3'. And the most recently mounted mount + on 'B2' at dentry 'b' is 'C2', and that of mount 'B3' is 'C3'. + + So all 'C1', 'C2' and 'C3' should be unmounted. + + If any of 'C2' or 'C3' has some child mounts, then that mount is not + unmounted, but all other mounts are unmounted. However if 'C1' is told + to be unmounted and 'C1' has some sub-mounts, the umount operation is + failed entirely. + +5g) Clone Namespace + + A cloned namespace contains all the mounts as that of the parent + namespace. + + Lets say 'A' and 'B' are the corresponding mounts in the parent and the + child namespace. + + If 'A' is shared, then 'B' is also shared and 'A' and 'B' propagate to + each other. + + If 'A' is a slave mount of 'Z', then 'B' is also the slave mount of + 'Z'. + + If 'A' is a private mount, then 'B' is a private mount too. + + If 'A' is unbindable mount, then 'B' is a unbindable mount too. + + +6) Quiz + + A.

Lets call this mount 'C' + + 'B' is the slave of 'A' and 'C' is a slave of 'B' + A -> B -> C + + at this point if we execute the following command + + mount --bind /bin /tmp/test + + The mount is attempted on 'A' + + will the mount propagate to 'B' and 'C' ? + + what would be the contents of + /mnt/1/test be? + +7) FAQ + + Q1. Why is bind mount needed? How is it different from symbolic links? + symbolic links can get stale if the destination mount gets + unmounted or moved. Bind mounts continue to exist even if the + other mount is unmounted or moved. + + Q2. Why can't the shared subtree be implemented using exportfs? + + exportfs is a heavyweight way of accomplishing part of what + shared subtree can do. I cannot imagine a way to implement the + semantics of slave mount using exportfs? + + Q3 Why is unbindable mount needed? + + Lets say we want to replicate the mount tree at multiple + locations within the same subtree. + + if one rbind mounts a tree within the same subtree 'n' times + the number of mounts created is an exponential function of 'n'. + Having unbindable mount can help prune the unneeded bind + mounts. Here is a example. + + step 1: + lets say the root tree has just two directories with + one vfsmount. + root + / \ + tmp usr + + And we want to replicate the tree at multiple + mountpoints under /root/tmp + + step2: + mount --make-shared /root + + mkdir -p /tmp/m1 + + mount --rbind /root /tmp/m1 + + the new tree now looks like this: + + root + / \ + tmp usr + / + m1 + / \ + tmp usr + / + m1 + + it has two vfsmounts + + step3: + mkdir -p /tmp/m2 + mount --rbind /root /tmp/m2 + + the new tree now looks like this: + + root + / \ + tmp usr + / \ + m1 m2 + / \ / \ + tmp usr tmp usr + / \ / + m1 m2 m1 + / \ / \ + tmp usr tmp usr + / / \ + m1 m1 m2 + / \ + tmp usr + / \ + m1 m2 + + it has 6 vfsmounts + + step 4: + mkdir -p /tmp/m3 + mount --rbind /root /tmp/m3 + + I wont' draw the tree..but it has 24 vfsmounts + + + at step i the number of vfsmounts is V[i] = i*V[i-1]. + This is an exponential function. And this tree has way more + mounts than what we really needed in the first place. + + One could use a series of umount at each step to prune + out the unneeded mounts. But there is a better solution. + Unclonable mounts come in handy here. + + step 1: + lets say the root tree has just two directories with + one vfsmount. + root + / \ + tmp usr + + How do we set up the same tree at multiple locations under + /root/tmp + + step2: + mount --bind /root/tmp /root/tmp + + mount --make-rshared /root + mount --make-unbindable /root/tmp + + mkdir -p /tmp/m1 + + mount --rbind /root /tmp/m1 + + the new tree now looks like this: + + root + / \ + tmp usr + / + m1 + / \ + tmp usr + + step3: + mkdir -p /tmp/m2 + mount --rbind /root /tmp/m2 + + the new tree now looks like this: + + root + / \ + tmp usr + / \ + m1 m2 + / \ / \ + tmp usr tmp usr + + step4: + + mkdir -p /tmp/m3 + mount --rbind /root /tmp/m3 + + the new tree now looks like this: + + root + / \ + tmp usr + / \ \ + m1 m2 m3 + / \ / \ / \ + tmp usr tmp usr tmp usr + +8) Implementation + +8A) Datastructure + + 4 new fields are introduced to struct vfsmount + ->mnt_share + ->mnt_slave_list + ->mnt_slave + ->mnt_master + + ->mnt_share links togather all the mount to/from which this vfsmount + send/receives propagation events. + + ->mnt_slave_list links all the mounts to which this vfsmount propagates + to. + + ->mnt_slave links togather all the slaves that its master vfsmount + propagates to. + + ->mnt_master points to the master vfsmount from which this vfsmount + receives propagation. + + ->mnt_flags takes two more flags to indicate the propagation status of + the vfsmount.

But we forgot to convert one caller, when the real server for connection is unavailable caller should put the connection reference. It happens only when sysctl var expire_nodest_conn is set to 1 and such connections never expire.

This is necessary for Linux clients and servers to interoperate with Microsoft Point-to-Point Tunneling Protocol (PPTP) servers (either Microsoft PPTP servers or the poptop project) which use MPPE to encrypt data when creating a VPN. This patch differs from the kernel_ppp_mppe DKMS pacakge at pptpclient.sourceforge.net by utilizing the kernel crypto routines rather than providing its own SHA1 and arcfour implementations. Minor changes to ppp_generic.c try to prevent a link from disabling compression (in our case, the encryption) after it has started using compression (encryption). Feedback to please.

The bootmem allocator only allows a power of two alignments. This causes a BUG_ON for some nodes. For cpu only nodes just allocate with a PERCPU_PAGE_SIZE alignment. Some older firmware reports SLIT distances of 0xff and results in bestnode not being computed. This is now treated correctly. The failed allocation check was removed because it's redundant. The bootmem allocator already makes this check. This fix has been boot tested on 4 node machine which has 4 cpu only nodes and 1 memory node. Thanks to Pete Keilty for reporting this and helping me test it.

This is because the signal-trampoline will attempt to store fp-regs with stf.spill instructions, which will trap for misaligned addresses. This isn't terribly useful behavior. It's better to just always align the signal frame to the next lower 16-byte boundary.

This patch adds hooks to the scoop driver to allow machines to provide a custom control function for this and such a function is added for spitz/akita/borzoi. It also moves the gpio init code into the machine files as this is machine dependent and differs between some models. A couple of warnings when compiling for collie are also fixed.

If local timer interrupt happens in between, it can oops in send_group_sigqueue() while taking ->sighand->siglock == NULL. However, we can't change send_group_sigqueue() to check p->signal != NULL, because sys_timer_create() does get_task_struct() only in SIGEV_THREAD_ID case. So it is possible that this task_struct was already freed and we can't trust p->signal. This patch changes de_thread() so that leader released after exit_itimers() call.

For small allocations this isn't really seen, but when you start allocating 50000 pages of AGP space, for say, texture memory, then things can take seconds to complete. In some cases the situation is doubled or even quadrupled in the time due to SMP, or a deallocation, then a new reallocation. I've had a case of upto 20 seconds wait time to deallocate and reallocate AGP space. This patch fixes the problem by making it the caller's responsibility to call global_flush_tlb(), and so removes it from every instance of mapping a page into AGP space until the time that all change_page_attr() changes are done.

Since the current thread context is already holding the cpucontrol lock, we dont need to make another attempt to acquire it. Now we leave a trace in current->flags indicating current thread already is under cpucontrol lock held, so we dont attempt to do this another time.

However, that flag is only set at the top level, so if a symbol is first encountered as a dependency of another symbol it will be rechecked every time it is encountered until it's encountered at the top level. This patch adjusts the flag setting so that each symbol will only be checked once, regardless of whether it is first encountered at the top level, or while recursing down from another symbol. On complex configurations, this vastly speeds up scripts/kconfig/conf. The config in the powerpc merge tree is particularly bad: this patch reduces the time for 'scripts/kconfig/conf -o arch/powerpc/Kconfig' by a factor of 40 on a G5. That's even including the time to print the config, so the speedup in the actual checking is more likely 2 or 3 orders of magnitude.

This patch replaces expensive "/" and "%" with - cheap ">>" and "&" where possible. - -Changes from version 0.5 to version 0.5a -======================================== - - Zero the partial block following the end of the file when a file - is truncated. - - Dates updated in the copyright. - - More checks when the filesystem is mounted: the count of blocks, - fragments, and inodes per group is checked against the block size. - - The buffers used by the error routines are now static variables, to - avoid using space on the kernel stack, as requested by Linus. - - Some cleanups in the error messages (some versions of syslog contain - a bug which truncates an error message if it contains '\n'). - - Check that no data can be written to a file past the 2GB limit. - - The famous readdir() bug has been fixed by Stephen Tweedie. - - Added a revision level in the superblock. - - Full support for O_SYNC flag of the open system call. - - New mount options: `resuid=#uid' and `resgid=#gid'. `resuid' causes - ext2fs to consider user #uid like root for the reserved blocks. - `resgid' acts the same way with group #gid. New fields in the - superblock contain default values for resuid and resgid and can - be modified by tune2fs. - Idea comes from Rene Cougnenc . - - New mount options: `bsddf' and `minixdf'. `bsddf' causes ext2fs - to remove the blocks used for FS structures from the total block - count in statfs. With `minixdf', ext2fs mimics Minix behavior - in statfs (i.e. it returns the total number of blocks on the - partition). This is intended to make bde happy :-) - - New file attributes: - - Immutable files cannot be modified. Data cannot be written to - these files. They cannot be removed, renamed and new links cannot - be created. Even root cannot modify the files. He has to remove - the immutable attribute first. - - Append-only files: can only be written in append-mode when writing. - They cannot be removed, renamed and new links cannot be created. - Note: files may only be added to an append-only directory. - - No-dump files: the attribute is not used by the kernel. My port - of dump uses it to avoid backing up files which are not important. - - New check in ext2_check_dir_entry: the inode number is checked. - - Support for big file systems: the copy of the FS descriptor is now - dynamically allocated (previous versions used a fixed size array). - This allows to mount 2GB+ FS. - - Reorganization of the ext2_inode structure to allow other operating - systems to create specific fields if they use ext2fs as their native - file system. Currently, ext2fs is only implemented in Linux but - will soon be part of Gnu Hurd and of Masix. - -Changes from version 0.4b to version 0.5 -======================================== - - New superblock fields: s_lastcheck and s_checkinterval added - by Uwe Ohse to implement timedependent checks - of the file system - - Real random numbers for secure rm added by Pierre del Perugia - - - The mount warnings related to the state of a fs are not printed - if the fs is mounted read-only, idea by Nick Holloway - - -Changes from version 0.4a to version 0.4b -========================================= - - Copyrights changed to include the name of my laboratory. - - Clean up of balloc.c and ialloc.c. - - More consistency checks. - - Block preallocation added by Stephen Tweedie. - - Direct reads of directories disallowed. - - Readahead implemented in readdir by Stephen Tweedie. - - Bugs in block and inodes allocation fixed. - - Readahead implemented in ext2_find_entry by Chip Salzenberg. - - New mount options: - `check=none|normal|strict' - `debug' - `errors=continue|remount-ro|panic' - `grpid', `bsdgroups' - `nocheck' - `nogrpid', `sysvgroups' - - truncate() now tries to deallocate contiguous blocks in a single call - to ext2_free_blocks(). - - lots of cosmetic changes. - -Changes from version 0.4 to version 0.4a -======================================== - - the `sync' option support is now complete. Version 0.4 was not - supporting it when truncating a file. I have tested the synchronous - writes and they work but they make the system very slow :-( I have - to work again on this to make it faster. - - when detecting an error on a mounted filesystem, version 0.4 used - to try to write a flag in the super block even if the filesystem had - been mounted read-only. This is fixed. - - the `sb=#' option now causes the kernel code to use the filesystem - descriptors located at block #+1. Version 0.4 used the superblock - backup located at block # but used the main copy of the descriptors. - - a new file attribute `S' is supported. This attribute causes - synchronous writes but is applied to a file not to the entire file - system (thanks to Michael Kraehe for - suggesting it). - - the directory cache is inhibited by default. The cache management - code seems to be buggy and I have to look at it carefully before - using it again. - - deleting a file with the `s' attribute (secure deletion) causes its - blocks to be overwritten with random values not with zeros (thanks to - Michael A. Griffith for suggesting it). - - lots of cosmetic changes have been made. - -Changes from version 0.3 to version 0.4 -======================================= - - Three new mount options are supported: `check', `sync' and `sb=#'. - `check' tells the kernel code to make more consistency checks - when the file system is mounted. Currently, the kernel code checks - that the blocks and inodes bitmaps are consistent with the free - blocks and inodes counts. More checks will be added in future - releases. - `sync' tells the kernel code to use synchronous writes when updating - an inode, a bitmap, a directory entry or an indirect block. This - can make the file system much slower but can be a big win for files - recovery in case of a crash (and we can now say to the BSD folks - that Linux also supports synchronous updates :-). - `sb=#' tells the kernel code to use an alternate super block instead - of its master copy. `#' is the number of the block (counted in - 1024 bytes blocks) which contains the alternate super block. - An ext2 file system typically contains backups of the super block - at blocks 8193, 16385, and so on. - - I have change the meaning of the valid flag used by e2fsck. it - now contains the state of the file system. If the kernel code - detects an inconsistency while the file system is mounted, it flags - it as erroneous and e2fsck will detect that on next run. - - The super block now contains a mount counter. This counter is - incremented each time the file system is mounted read/write. When - this counter becomes bigger than a maximal mount counts (also stored - in the super block), e2fsck checks the file system, even if it had - been unmounted cleanly, and resets this counter to 0. - - File attributes are now supported. One can associate a set of - attributes to a file. Three attributes are defined: - `c': the file is marked for automatic compression, - `s': the file is marked for secure deletion: when the file is - deleted, its blocks are zeroed and written back to the disk, - `u': the file is marked for undeletion: when the file is deleted, - its contents are saved to allow a future undeletion. - Currently, only the `s' attribute is implemented in the kernel - code. Support for the other attributes will be added in a future - release. - - a few bugs related to times updates have been fixed by Bruce - Evans and me. - - a bug related to the links count of deleted inodes has been fixed. - Previous versions used to keep the links count set to 1 when a file - was deleted. The new version now sets links_count to 0 when deleting - the last link. - - a race condition when deallocating an inode has been fixed by - Stephen Tweedie. - -- cgit v0.10.2 From e4a53cbabc81f04e24a5570b4aa6a6384bdbfc67 Mon Sep 17 00:00:00 2001 From: "Gabriel A.

Unfortunately some callers of lookup_hash don't actually pass this one down. For lookup_one_len() we don't have a struct nameidata to pass down, but as this function is a library function only used by filesystem code this is an acceptable limitation. All other callers should pass down the nameidata, so this patch changes the lookup_hash interface to only take a struct nameidata argument and derives the other two arguments to __lookup_hash from it. All callers already have the nameidata argument available so this is not a problem. At the same time I'd like to deprecate the lookup_hash interface as there are better exported interfaces for filesystem usage. Before it can actually be removed I need to fix up rpc_pipefs.

After testing on NXT2002, we should deprecate the nxt2002 module, and implement this one instead on the applicable cards. * get_dvb_firmware: - Added support for the NXT2004 firmware. This firmware works with both the ATI HDTV Wonder and the AVerTVHD MCE a180. This was originally written by Jean-Francois Thibert * dvb-pll.c - Fixed minimum frequency for tuv1236d.

The problem happens when two sections begin in the same transport packet. The dvb_demux code resets its buffer only before the first of these sections. This means that when the second (or subsequent) section begins, there is up to 182 bytes of buffer space already used. If the following section is close to the maximum size, it currently won't fit in the (4096-byte) buffer and is thrown away. The fix is simply to enlarge the buffer by the size of one transport packet and correct one usage of the SECFEED_SIZE definition where what is really meant is the maximum size of a section.

It introduces an extra runqueue variable prio_bias which is the sum of the (inverted) static priorities of all the tasks on the runqueue. This is then used to bias busy rebalancing between runqueues to obtain good distribution of tasks of different nice values. By biasing the balancing only during busy rebalancing we can avoid having any significant loss of throughput by not affecting the carefully tuned idle balancing already in place. If all tasks are running at the same nice level this code should also have minimal effect. The code is optimised out in the !CONFIG_SMP case.

Also corrected a bugs in arm26's cpu_idle (make it actually call schedule()). How did it ever work before? Might fix the CPU hotplugging hang which Nigel Cunningham noted. We think the bug hits if the idle thread is preempted after checking need_resched() and before going to sleep, then the CPU offlined. After calling stop_machine_run, the CPU eventually returns from preemption and into the idle thread and goes to sleep. The CPU will continue executing previous idle and have no chance to call play_dead. By disabling preemption until we are ready to explicitly schedule, this bug is fixed and the idle threads generally become more robust.

Improves efficiency of resched_task and some cpu_idle routines. * In resched_task: - TIF_NEED_RESCHED is only cleared with the task's runqueue lock held, and as we hold it during resched_task, then there is no need for an atomic test and set there. The only other time this should be set is when the task's quantum expires, in the timer interrupt - this is protected against because the rq lock is irq-safe. - If TIF_NEED_RESCHED is set, then we don't need to do anything. It won't get unset until the task get's schedule()d off. - If we are running on the same CPU as the task we resched, then set TIF_NEED_RESCHED and no further action is required. - If we are running on another CPU, and TIF_POLLING_NRFLAG is *not* set after TIF_NEED_RESCHED has been set, then we need to send an IPI. Using these rules, we are able to remove the test and set operation in resched_task, and make clear the previously vague semantics of POLLING_NRFLAG. * In idle routines: - Enter cpu_idle with preempt disabled. When the need_resched() condition becomes true, explicitly call schedule(). This makes things a bit clearer (IMO), but haven't updated all architectures yet. - Many do a test and clear of TIF_NEED_RESCHED for some reason. According to the resched_task rules, this isn't needed (and actually breaks the assumption that TIF_NEED_RESCHED is only cleared with the runqueue lock held). So remove that. Generally one less locked memory op when switching to the idle thread. - Many idle routines clear TIF_POLLING_NRFLAG, and only set it in the inner most polling idle loops. The above resched_task semantics allow it to be set until before the last time need_resched() is checked before going into a halt requiring interrupt wakeup. Many idle routines simply never enter such a halt, and so POLLING_NRFLAG can be always left set, completely eliminating resched IPIs when rescheduling the idle task. POLLING_NRFLAG width can be increased, to reduce the chance of resched IPIs.

However, a value of 4 empirically works better at bpp = 8, and 2 for 16 and 32. This buglet was exposed by the rotation code. Second fix is the unconditional call to update_start() without verifying if the offsets are correct. Remove this call, it's not necessary and secondly, it causes a crash with invalid values.

Daplas" Date: Tue, 8 Nov 2005 21:39:09 -0800 Subject: [PATCH] fbcon: Console Rotation - Prepare fbcon for console rotation This patch series implements generic code to rotate the console at 90, 180, and 270 degrees. The implementation is completely done in the framebuffer console level, thus no changes to the framebuffer layer or to the drivers are needed. Console rotation is required by some Sharp-based devices where the natural orientation of the display is not at 0 degrees. Also, users that have displays that can pivot will benefit by having a console in portrait mode if they so desire. The choice to implement the code in the console layer rather than in the framebuffer layer is due to the following reasons: - it's fast - it does not require driver changes - it can coexist with devices that can rotate the display at the hardware level - it complements graphics applications that can do display rotation The changes to core fbcon are minimal-- recognition of the console rotation angle so it can swap directions, origins and axes (xres vs yres, xpanstep vs ypanstep, xoffset vs yoffset, etc) and storage of the rotation angle per display. The bulk of the code that does the actual drawing to the screen are placed in separate files. Each angle of rotation has separate methods (bmove, clear, putcs, cursor, update_start which is derived from update_var, and clear_margins). To mimimize processing time, the fontdata are pre-rotated at each console switch (only if the font or the angle has changed). The option can be compiled out (CONFIG_FRAMEBUFFER_CONSOLE_ROTATION = n) if rotation is not needed. Choosing the rotation angle can be done in several ways: 1. boot option fbcon=rotate:n, where n = 0 - normal n = 1 - 90 degrees (clockwise) n = 2 - 180 degrees (upside down) n = 3 - 270 degrees (counterclockwise) 2. echo n > /sys/class/graphics/fb[num]/con_rotate where n is the same as described above. It sets the angle of rotation of the current console 3 echo n > /sys/class/graphics/fb[num]/con_rotate_all where n is the same as described above. Globally sets the angle of rotation. GOTCHAS: The option, especially at angles of 90 and 270 degrees, will exercise the least used code of drivers. Namely, at these angles, panning is done in the x-axis, so it can reveal bugs in the driver if xpanstep is set incorrectly. A workaround is to set xpanstep = 0. Secondly, at these angles, the framebuffer memory access can be unaligned if (fontheight * bpp) % 32 ~= 0 which can reveal bugs in the drivers imageblit, fillrect and copyarea functions. (I think cfbfillrect may have this buglet). A workaround is to use a standard 8x16 font. Speed: The scrolling speed difference between 0 and 180 degrees is minimal, somewhere areound 1-2%. At 90 or 270 degress, speed drops down to a vicinity of 30-40%. This is understandable because the blit direction is across the framebuffer "direction." Scrolling will be helped at these angles if xpanstep is not equal to zero, use of 8x16 fonts, and setting xres_virtual >= xres * 2. Note: The code is tested on little-endian only, so I don't know if it will work in big-endian. Please let me know, it will take only less than a minute of your time. This patch prepares fbcon for console rotation and contains the following changes: - add rotate field in struct fbcon_ops to keep fbcon's current rotation angle - add con_rotate field in struct display to store per-display rotation angle - create a private copy of the current var to fbcon. This will prevent fbcon from directly manipulating info->var, especially the fields xoffset, yoffset and vmode. - add ability to swap pertinent axes (xres, yres; xpanstep, ypanstep; etc) depending on the rotation angle - change global update_var() (function that sets the screen start address) as an fbcon method update_start. This is required because the axes, start offset, and/or direction can be reversed depending on the rotation angle. - add fbcon method rotate_font() which will rotate each character bitmap to the correct angle of rotation. - add fbcon boot option 'rotate' to select the angle of rotation at bootime. Currently does nothing until all patches are applied.

Daplas" Date: Tue, 8 Nov 2005 21:39:11 -0800 Subject: [PATCH] fbcon: Console Rotation - Add support to rotate font bitmap Add support to rotate the font bitmap. To save on processing time, the entire fontdata will be rotated on a console switch, then stored in a buffer private to fbcon. To further save on processing, the fontdata will only be rotated if the font has changed or if the angle of rotation has changed. Only a single copy of the rotated fontdata will be kept.

Daplas" Date: Tue, 8 Nov 2005 21:39:15 -0800 Subject: [PATCH] fbcon: Console Rotation - Add ability to control rotation via sysfs Add ability to set rotation via sysfs. The attributes are located in /sys/class/graphics/fb[n] and accepts 0 - unrotated; 1 - clockwise; 2 - upside down; 3 - counterclockwise. The attributes are: con_rotate (r/w) - set rotation of the active console con_rotate_all (w) - set rotation of all consoles rotate (r/w) - set rotation of the framebuffer, if supported. Currently, none of the drivers support this. This is probably temporary, since con_rotate and con_rotate_all are console-specific and has no business being under the fb device. However, until the console layer acquires it's own sysfs class, these attributes will temporarily reside here.

The module will be fbcon. + + In order for fbcon to activate, at least one framebuffer driver is +required, so choose from any of the numerous drivers available. For x86 +systems, they almost universally have VGA cards, so vga16fb and vesafb will +always be available. However, using a chipset-specific driver will give you +more speed and features, such as the ability to change the video mode +dynamically. + + To display the penguin logo, choose any logo available in Logo +Configuration->Boot up logo. + + Also, you will need to select at least one compiled-in fonts, but if +you don't do anything, the kernel configuration tool will select one for you, +usually an 8x16 font. + +GOTCHA: A common bug report is enabling the framebuffer without enabling the +framebuffer console. Depending on the driver, you may get a blanked or +garbled display, but the system still boots to completion. If you are +fortunate to have a driver that does not alter the graphics chip, then you +will still get a VGA console. + +B. Loading + +Possible scenarios: + +1. Driver and fbcon are compiled statically + + Usually, fbcon will automatically take over your console. The notable + exception is vesafb. It needs to be explicitly activated with the + vga= boot option parameter. + +2. Driver is compiled statically, fbcon is compiled as a module + + Depending on the driver, you either get a standard console, or a + garbled display, as mentioned above. To get a framebuffer console, + do a 'modprobe fbcon'. + +3. Driver is compiled as a module, fbcon is compiled statically + + You get your standard console. Once the driver is loaded with + 'modprobe xxxfb', fbcon automatically takes over the console with + the possible exception of using the fbcon=map:n option. See below. + +4. Driver and fbcon are compiled as a module. + + You can load them in any order. Once both are loaded, fbcon will take + over the console. + +C. Boot options + + The framebuffer console has several, largely unknown, boot options + that can change its behavior. + +1. fbcon=font: + + Select the initial font to use. The value 'name' can be any of the + compiled-in fonts: VGA8x16, 7x14, 10x18, VGA8x8, MINI4x6, RomanLarge, + SUN8x16, SUN12x22, ProFont6x11, Acorn8x8, PEARL8x8. + + Note, not all drivers can handle font with widths not divisible by 8, + such as vga16fb. + +2. fbcon=scrollback:[k] + + The scrollback buffer is memory that is used to preserve display + contents that has already scrolled past your view. This is accessed + by using the Shift-PageUp key combination. The value 'value' is any + integer. It defaults to 32KB. The 'k' suffix is optional, and will + multiply the 'value' by 1024. + +3. fbcon=map:<0123> + + This is an interesting option. It tells which driver gets mapped to + which console. The value '0123' is a sequence that gets repeated until + the total length is 64 which is the number of consoles available. In + the above example, it is expanded to 012301230123... and the mapping + will be: + + tty | 1 2 3 4 5 6 7 8 9 ... + fb | 0 1 2 3 0 1 2 3 0 ... + + ('cat /proc/fb' should tell you what the fb numbers are) + + One side effect that may be useful is using a map value that exceeds + the number of loaded fb drivers. For example, if only one driver is + available, fb0, adding fbcon=map:1 tells fbcon not to take over the + console. + + Later on, when you want to map the console the to the framebuffer + device, you can use the con2fbmap utility. + +4. fbcon=vc:- + + This option tells fbcon to take over only a range of consoles as + specified by the values 'n1' and 'n2'. The rest of the consoles + outside the given range will still be controlled by the standard + console driver. + + NOTE: For x86 machines, the standard console is the VGA console which + is typically located on the same video card. Thus, the consoles that + are controlled by the VGA console will be garbled. + +4. fbcon=rotate: + + This option changes the orientation angle of the console display. The + value 'n' accepts the following: + + 0 - normal orientation (0 degree) + 1 - clockwise orientation (90 degrees) + 2 - upside down orientation (180 degrees) + 3 - counterclockwise orientation (270 degrees) + + The angle can be changed anytime afterwards by 'echoing' the same + numbers to any one of the 2 attributes found in + /sys/class/graphics/fb{x} + + con_rotate - rotate the display of the active console + con_rotate_all - rotate the display of all consoles + + Console rotation will only become available if Console Rotation + Support is compiled in your kernel. + + NOTE: This is purely console rotation. Any other applications that + use the framebuffer will remain at their 'normal'orientation. + Actually, the underlying fb driver is totally ignorant of console + rotation. + +--- +Antonino Daplas -- cgit v0.10.2 From 120ddb41f18c2d41702af561f4acfbcbd8d6fb46 Mon Sep 17 00:00:00 2001 From: "Antonino A.
