When a hole punch is passed through, the page cache is not cleared and thus allows reading stale data from the cache. This is easily demonstrable (using FOPEN_KEEP_CACHE) by reading a smallish random data file into cache, punching a hole and creating a copy of the file. Drop caches or remount and observe that the original file no longer matches the file copied after the hole punch. The original file contains a zeroed range and the latter file contains stale data. Protect against writepage requests in progress and punch out the associated page cache range after a successful client fs hole punch.

The problem is that the futex code needs to perform certain ops (cmpxchg, set, add, or, andn, xor) atomically on user-space addresses, and M68K's lack of a futex.h causes those operations to be unsupported and disabled. This patch adds that support, but only for uniprocessor machines, which is adequate for M68K. For UP it's enough to disable preemption to ensure mutual exclusion (futexes don't need to care about other hardware agents), and the mandatory pagefault_disable() does just that. This patch is closely based on the one I co-wrote for UP ARM back in August 2008. The main change is that this patch uses the C get_user/put_user accessors instead of inline assembly code with exception table fixups. For non-MMU machines the new futex.h simply redirects to the generic futex.h, so there is no functional change for them. Tested on aranym with the glibc-2.17 test suite: no regressions, and a number of mutex/condvar test cases went from failing to succeeding (tst-mutexpi{5,5a,6,9}, tst-cond2[45], tst-robust[1-9], tst-robustpi[1-8]). Also tested with glibc-2.18 HEAD and a local glibc patch to enable PI mutexes: no regressions.

This wasn't enforced though if only the FB changed, everything else (format, connector etc.) remaining the same. In this case we only set the new FB base and left the connector in the old power save mode. Fix this by forcing a full modeset whenever there is an attached FB and any affected connector is in a power save mode. V_2: Run the test for encoders in power save mode outside the the test for fb change: user space may have just disabled the encoders but left everything else in place. Make sure the connector list is not empty before running this test.

The reason is that the s390 asm/io.h file includes the asm-generic/io.h file which then defines xlate_dev_mem_ptr() and therefore overwrites the s390 specific version that does the correct swap operation for prefix and absolute zero pages. The problem is a regression that was introduced with git commit cd248341 (s390/pci: base support). To fix the problem add "#ifndef xlate_dev_mem_ptr" in asm-generic/io.h and "#define xlate_dev_mem_ptr" in asm/io.h. This ensures that the s390 version is used. For completeness also add the "#ifndef" construct for xlate_dev_kmem_ptr().

Since mac80211 has proper synchronization for aggregation session start/stop handling, a better approach to session handling is to simply allow mac80211 to start a new session at any time.

This meant that the .dts file passed to dtc is not the original, but the preprocessed one. When compiling with a separate build directory (i.e., with O=), this preprocessed file will not live in the same directory as the original. When the .dts file includes .dtsi files, dtc will look for them in the build directory, not in the source directory and compilation will fail. The commit referenced above tried to fix this by passing arch/*/boot/dts as an include path to dtc. However, for mips, the .dts files are not in this directory, so dts compilation on mips breaks for some targets. Instead of hardcoding this particular include path, this commit just uses the directory of the .dts file that is being compiled, which effectively restores the previous behaviour wrt includes. For most .dts files, this path is just the same as the previous hardcoded arch/*/boot/dts path. This was tested on a mips (rt3052) and an arm (bcm2835) target.

This is caused by the fact that omapdss+DT is not yet supported, and thus omapdss is not probed at all. On the other hand, omapfb is always probed. When omapfb tries to use omapdss, there's a NULL pointer dereference crash. The same error should most likely happen with omapdrm and omap_vout also. To fix this, add an "initialized" state to omapdss. When omapdss has been probed, it's marked as initialized. omapfb, omapdrm and omap_vout check this state when they are probed to see that omapdss is actually there.

[..] If I remove the --limit-iface-in from the non-working scenario, so just use the -m addrtype --dst-type LOCAL it works! This happens when LOCAL type matching is requested with --limit-iface-in, and the default ipv6 route is via the interface the packet we test arrived on. Because xt_addrtype uses ip6_route_output, the ipv6 routing implementation creates an unwanted cached entry, and the packet won't make it to the real/expected destination. Silently ignoring --limit-iface-in makes the routing work but it breaks rule matching (--dst-type LOCAL with limit-iface-in is supposed to only match if the dst address is configured on the incoming interface; without --limit-iface-in it will match if the address is reachable via lo). The test should call ipv6_chk_addr() instead. However, this would add a link-time dependency on ipv6. There are two possible solutions: 1) Revert the commit that moved ipt_addrtype to xt_addrtype, and put ipv6 specific code into ip6t_addrtype. 2) add new "nf_ipv6_ops" struct to register pointers to ipv6 functions. While the former might seem preferable, Pablo pointed out that there are more xt modules with link-time dependeny issues regarding ipv6, so lets go for 2).

The nop tracer is just a stub tracer that is used to have no tracer enabled. It is assigned at early bootup as it is the default tracer. But if ftrace=nop is on the kernel command line, the registering of the nop tracer will call tracing_set_tracer() which will try to execute the nop tracer. But it expects tr->current_trace to be assigned something as it usually is assigned to the nop tracer. As it hasn't been assigned to anything yet, it causes the system to crash. The simple fix is to move the tr->current_trace = nop before registering the nop tracer. The functionality is still the same as the nop tracer doesn't do anything anyway.

To fix the crash, exclude these from queue accounting here and just start their netdev queues unconditionally. For monitor, this is the best we can do, as we can redirect frames there to any other interface and don't know which one that will since it can be different for each frame.

There's no reason to have the early exit path. Remove it along with the later assumption that the subtree isn't empty. This simplifies the code a bit and fixes the subtle bug. While at it, fix the comment of cgroup_for_each_descendant_pre() which was incorrectly referring to ->css_offline() instead of ->css_online().

The fix created a timer, comp_mode_recovery_timer, which is deleted from a timer list when xhci_suspend() is called. However, the hibernate image, including the timer list containing the comp_mode_recovery_timer, had already been saved before the timer was deleted. Upon resume from hibernate, the list containing the comp_mode_recovery_timer is restored from the image saved to disk, and xhci_resume(), assuming that the timer had been deleted by xhci_suspend(), makes a call to compliance_mode_recoery_timer_init(), which creates a new instance of the comp_mode_recovery_timer and attempts to place it into the same list in which it is already active, thus corrupting the list during the list_add() call. At this point, a call trace is emitted indicating the list corruption. Soon afterward, the system locks up, the watchdog times out, and the ensuing NMI crashes the system. The problem did not occur when resuming from suspend. In suspend, the image in RAM remains exactly as it was when xhci_suspend() deleted the comp_mode_recovery_timer, so there is no problem when xhci_resume() creates a new instance of this timer and places it in the still empty list. This patch avoids the problem by deleting the timer in xhci_resume() when resuming from hibernate. Now xhci_resume() can safely make the call to create a new instance of this timer, whether returning from suspend or hibernate. Thanks to Alan Stern for his help with understanding the problem. [Sarah reworked this patch to cover the case where the xHCI restore register operation fails, and (temp & STS_SRE) is true (and we re-init the host, including re-init for the compliance mode), but hibernate is false. The original patch would have caused list corruption in this case.] This patch should be backported to kernels as old as 3.2, that contain the commit 71c731a296f1b08a3724bd1b514b64f1bda87a23 "usb: host: xhci: Fix Compliance Mode on SN65LVPE502CP Hardware" Signed-off-by: Tony Camuso Tested-by: Tony Camuso Acked-by: Don Zickus Signed-off-by: Sarah Sharp Cc: stable@vger.kernel.org diff --git a/drivers/usb/host/xhci.c b/drivers/usb/host/xhci.c index b4aa79d..ae59119 100644 --- a/drivers/usb/host/xhci.c +++ b/drivers/usb/host/xhci.c @@ -956,6 +956,7 @@ int xhci_resume(struct xhci_hcd *xhci, bool hibernated) struct usb_hcd *hcd = xhci_to_hcd(xhci); struct usb_hcd *secondary_hcd; int retval = 0; + bool comp_timer_running = false; /* Wait a bit if either of the roothubs need to settle from the * transition into bus suspend. @@ -993,6 +994,13 @@ int xhci_resume(struct xhci_hcd *xhci, bool hibernated) /* If restore operation fails, re-initialize the HC during resume */ if ((temp & STS_SRE) || hibernated) { + + if ((xhci->quirks & XHCI_COMP_MODE_QUIRK) && + !(xhci_all_ports_seen_u0(xhci))) { + del_timer_sync(&xhci->comp_mode_recovery_timer); + xhci_dbg(xhci, "Compliance Mode Recovery Timer deleted!\n"); + } + /* Let the USB core know _both_ roothubs lost power. */ usb_root_hub_lost_power(xhci->main_hcd->self.root_hub); usb_root_hub_lost_power(xhci->shared_hcd->self.root_hub); @@ -1035,6 +1043,8 @@ int xhci_resume(struct xhci_hcd *xhci, bool hibernated) retval = xhci_init(hcd->primary_hcd); if (retval) return retval; + comp_timer_running = true; + xhci_dbg(xhci, "Start the primary HCD\n"); retval = xhci_run(hcd->primary_hcd); if (!retval) { @@ -1076,7 +1086,7 @@ int xhci_resume(struct xhci_hcd *xhci, bool hibernated) * to suffer the Compliance Mode issue again.

Some xHCI hosts contain a "redriver" from TI that silently drops port status connect changes if the port slips into Compliance Mode. If the port slips into compliance mode while the host is in D0, there will not be a port status change event. If the port slips into compliance mode while the host is in D3, the host will not send a PME. This includes when the system is suspended (S3) or hibernated (S4). If this happens when the system is in S3/S4, there is nothing software can do. Other port status change events that would normally cause the host to wake the system from S3/S4 may also be lost. This includes remote wakeup, disconnects and connects on other ports, and overrcurrent events. A decision was made to _NOT_ disable system suspend/hibernate on these systems, since users are unlikely to enable wakeup from S3/S4 for the xHCI host. Software can deal with this issue when the system is in S0. A work around was put in to poll the port status registers for Compliance Mode. The xHCI driver will continue to poll the registers while the host is runtime suspended. Unfortunately, that means we can't allow the PCI device to go into D3cold, because power will be removed from the host, and the config space will read as all Fs. Disable D3cold in the xHCI PCI runtime suspend function.

If the enabled cpu receives an interrupt and as a result sends an IPI to the to be offlined cpu in its bottom halve context, the IPI won't be noticed before the cpu is offline.

If the AP_VLAN interface was registered after the AP it belongs to (which is the typical case) and then we get into this code path, unregister_netdevice_many() will crash because it isn't prepared to deal with interfaces being closed in the middle of it. Exactly this happens though, because we iterate the list, find the AP master this AP_VLAN belongs to and dev_close() the dependent VLANs. After this, unregister_netdevice_many() won't pick up the fact that the AP_VLAN is already down and will do it again, causing a crash.

If these regulators are marked as 'always on', there is a potential for power-loss. If they're not and are seemingly unused the Regulator subsystem will attempt to disable them to save power. This causes an issue for AUX1, AUX2 and AUX3 as they obtain their power from EXT3. So we're specifying that here to prevent EXT3 from being powered down.

This leads to __build_flow_key() getting pointer to IPv4 header of the ICMP redirect packet rather than pointer to the embedded IPv4 header of the packet initiating the redirect. As a result, handling of ICMP redirects initiated by TCP packets is broken. Issue was introduced by 4895c771c ("ipv4: Add FIB nexthop exceptions.")

Meelis reported that the warning triggers. There are two corner cases which have been not considered: 1) cpuidle calls clockevents_notify(CLOCK_EVT_NOTIFY_BROADCAST_ENTER) twice. That can result in the following scenario CPU0 CPU1 cpuidle_idle_call() clockevents_notify(CLOCK_EVT_NOTIFY_BROADCAST_ENTER) set cpu in tick_broadcast_oneshot_mask broadcast interrupt event expired for cpu1 set pending bit acpi_idle_enter_simple() clockevents_notify(CLOCK_EVT_NOTIFY_BROADCAST_ENTER) WARN_ON(pending bit) Move the WARN_ON into the section where we enter broadcast mode so it wont provide false positives on the second call. 2) safe_halt() enables interrupts, so a broadcast interrupt can be delivered befor the broadcast mode is disabled. That sets the pending bit for the CPU which receives the broadcast interrupt. Though the interrupt is delivered right away from the broadcast handler and leaves the pending bit stale. Clear the pending bit for the current cpu in the broadcast handler. Reported-and-tested-by: Meelis Roos Cc: Len Brown Cc: Frederic Weisbecker Cc: Borislav Petkov Cc: Rafael J.

This was unproblematic until b73690c8f8b5d: "ARM: Kirkwood: Support basic hotplug for PCI-E" which changes the way the PCIe bus is initialized. The non-DT ts219-setup.c now crashes during boot.

Since commit 31ade30692dc9680bfc95700d794818fa3f754ac, timekeeping_init() checks for presence of persistent clock by attempting to read a non-zero time value. This is an issue on platforms where persistent_clock (instead is implemented as a free-running counter (instead of an RTC) starting from zero on each boot and running during suspend. Examples are some ARM platforms (e.g. PandaBoard). An attempt to read such a clock during timekeeping_init() may return zero value and falsely declare persistent clock as missing. Additionally, in the above case suspend times may be accounted twice (once from timekeeping_resume() and once from rtc_resume()), resulting in a gradual drift of system time. This patch does a run-time correction of the issue by doing the same check during timekeeping_suspend(). A better long-term solution would have to return error when trying to read non-existing clock and zero when trying to read an uninitialized clock, but that would require changing all persistent_clock implementations. This patch addresses the immediate breakage, for now.

And commit 8170e6bed465b4b0c7687f93e9948aca4358a33b x86, 64bit: Use a #PF handler to materialize early mappings on demand said: During the switchover in head_64.S, before #PF handler is available, we use three pages to handle kernel crossing 1G, 512G boundaries with sharing page by playing games with page aliasing: the same page is mapped twice in the higher-level tables with appropriate wraparound. But from the switchover code, when we set up the PUD table: 114 addq $4096, %rdx 115 movq %rdi, %rax 116 shrq $PUD_SHIFT, %rax 117 andl $(PTRS_PER_PUD-1), %eax 118 movq %rdx, (4096+0)(%rbx,%rax,8) 119 movq %rdx, (4096+8)(%rbx,%rax,8) It seems line 119 has a potential bug there. For example, if the kernel is loaded at physical address 511G+1008M, that is 000000000 111111111 111111000 000000000000000000000 and the kernel _end is 512G+2M, that is 000000001 000000000 000000001 000000000000000000000 So in this example, when using the 2nd page to setup PUD (line 114~119), rax is 511. In line 118, we put rdx which is the address of the PMD page (the 3rd page) into entry 511 of the PUD table. But in line 119, the entry we calculate from (4096+8)(%rbx,%rax,8) has exceeded the PUD page. IMO, the entry in line 119 should be wraparound into entry 0 of the PUD table. The patch fixes the bug.

However, if the root cgroup does not mounted with __DEVEL__sane_hehavior, to create a new cgroup with xattr option will succeed although after that the EA function does not works as expected but will get ENOTSUPP for setting up attributes under either cgroup. e.g. setfattr: /cgroup2/test: Operation not supported Instead of keeping silence in this case, it's better to drop a log entry in warning level. That would be helpful to understand the reason behind the scene from the user's perspective, and this is essentially an improvement does not break the backward compatibilities. With this fix, above mount attemption will keep up works as usual but the following line cound be found at the system log: [ ...] cgroup: new mount options do not match the existing superblock tj: minor formatting / message updates.

The commit was valid -- it fixed a real bug -- but the periodic scheduler in ehci-hcd is in such bad shape (especially the part that handles split transactions) that fixing one bug is very likely to cause another to surface. That's what happened in this case; the result was choppy and noisy playback on certain 24-bit audio devices. The only real fix will be to rewrite this entire section of code. My next project...

This will result a mismatch between the number the queues in netdev and tuntap. This is because we only allocate a 1q netdevice when IFF_MULTI_QUEUE was not specified, so when we set the IFF_MULTI_QUEUE and try to attach more queues later, netif_set_real_num_tx_queues() may fail which result a single queue netdevice with multiple sockets attached. Solve this by disallowing changing the mq flag for persistent device. Bug was introduced by commit edfb6a148ce62e5e19354a1dcd9a34e00815c2a1 (tuntap: reduce memory using of queues).

This creates a further reference to the menu's visibilities and when the expression reduction functions do their work, they may remove or modify expressions that have multiple references, thus causing unpredictable side-effects. The following example Kconfig constructs a case where this causes problems: a menu and a prompt which's visibilities depend on the same symbol. When invoking mconf with this Kconfig and pressing "Z" we see a problem caused by a free'd expression still referenced by the menu's visibility: ------------------------------------------------------------------------ mainmenu "Kconfig Testing Configuration" config VISIBLE def_bool n config Placeholder bool "Place holder" menu "Invisible" visible if VISIBLE config TEST_VAR bool "Test option" if VISIBLE endmenu ------------------------------------------------------------------------ This patch fixes this problem by creating copies of the menu's visibility expressions before AND-ing them with the prompt's one.

The original commit was done under the incorrect assumption that it's safe to walk se_sess->sess_cmd_list unprotected in target_wait_for_sess_cmds() after sess->sess_tearing_down = 1 has been set by target_sess_cmd_list_set_waiting() during session shutdown. So instead of adding sess->sess_cmd_lock protection around sess->sess_cmd_list during target_wait_for_sess_cmds(), switch back to sess->sess_wait_list to allow wait_for_completion() + TFO->release_cmd() to occur without having to walk ->sess_cmd_list after the list_splice. Also add a check to exit if target_sess_cmd_list_set_waiting() has already been called, and add a WARN_ON to check for any fabric bug where new se_cmds are added to sess->sess_cmd_list after sess->sess_tearing_down = 1 has already been set.

WARNING: at .../drivers/pci/search.c:214 pci_get_dev_by_id+0x8a/0x90() This occurred because a call to pci_get_domain_bus_and_slot() was added to cper_print_pcie() to setup for the call to cper_print_aer(). The warning showed up because cper_print_pcie() is called in an interrupt context and pci_get* functions are not supposed to be called in that context.

Commit 4580a92d44 "NFS: Use server-recommended security flavor by default (NFSv3)" introduced a behavior regression for NFS mounts done via a legacy binary mount(2) call. Ensure that a default security flavor is specified for legacy binary mount requests, since they do not invoke nfs_select_flavor() in the kernel. Busybox uses klibc's nfsmount command, which performs NFS mounts using the legacy binary mount data format. /sbin/mount.nfs is not affected by this regression. Reported-by: Darrick J.

It's been a long time since that has been done in XFS, and the changes to log the entire inode buffers for CRC enabled filesystems has re-introduced that corner case. And, of course, it turns out that the above commit didn't actually fix anything - it just ensured that log recovery is guaranteed to fail when this situation occurs. And now for the gory details. xfstest xfs/085 is failing with this assert: XFS (vdb): bad number of regions (0) in inode log format XFS: Assertion failed: 0, file: fs/xfs/xfs_log_recover.c, line: 1583 Largely undocumented factoid #1: Log recovery depends on all log buffer format items starting with this format: struct foo_log_format { __uint16_t type; __uint16_t size; .... As recoery uses the size field and assumptions about 32 bit alignment in decoding format items. So don't pay much attention to the fact log recovery thinks that it decoding an inode log format item - it just uses them to determine what the size of the item is. But why would it see a log format item with a zero size? Well, luckily enough xfs_logprint uses the same code and gives the same error, so with a bit of gdb magic, it turns out that it isn't a log format that is being decoded. What logprint tells us is this: Oper (130): tid: a0375e1a len: 28 clientid: TRANS flags: none BUF: #regs: 2 start blkno: 144 (0x90) len: 16 bmap size: 2 flags: 0x4000 Oper (131): tid: a0375e1a len: 4096 clientid: TRANS flags: none BUF DATA ---------------------------------------------------------------------------- Oper (132): tid: a0375e1a len: 4096 clientid: TRANS flags: none xfs_logprint: unknown log operation type (4e49) ********************************************************************** * ERROR: data block=2 * ********************************************************************** That we've got a buffer format item (oper 130) that has two regions; the format item itself and one dirty region. The subsequent region after the buffer format item and it's data is them what we are tripping over, and the first bytes of it at an inode magic number. Not a log opheader like there is supposed to be. That means there's a problem with the buffer format item. It's dirty data region is 4096 bytes, and it contains - you guessed it - initialised inodes. But inode buffers are 8k, not 4k, and we log them in their entirety. So something is wrong here. The buffer format item contains: (gdb) p /x *(struct xfs_buf_log_format *)in_f $22 = {blf_type = 0x123c, blf_size = 0x2, blf_flags = 0x4000, blf_len = 0x10, blf_blkno = 0x90, blf_map_size = 0x2, blf_data_map = {0xffffffff, 0xffffffff, .... }} Two regions, and a signle dirty contiguous region of 64 bits. 64 * 128 = 8k, so this should be followed by a single 8k region of data. And the blf_flags tell us that the type of buffer is a XFS_BLFT_DINO_BUF. It contains inodes. And because it doesn't have the XFS_BLF_INODE_BUF flag set, that means it's an inode allocation buffer. So, it should be followed by 8k of inode data. But we know that the next region has a header of: (gdb) p /x *ohead $25 = {oh_tid = 0x1a5e37a0, oh_len = 0x100000, oh_clientid = 0x69, oh_flags = 0x0, oh_res2 = 0x0} and so be32_to_cpu(oh_len) = 0x1000 = 4096 bytes. It's simply not long enough to hold all the logged data. There must be another region. There is - there's a following opheader for another 4k of data that contains the other half of the inode cluster data - the one we assert fail on because it's not a log format header. So why is the second part of the data not being accounted to the correct buffer log format structure? It took a little more work with gdb to work out that the buffer log format structure was both expecting it to be there but hadn't accounted for it. It was at that point I went to the kernel code, as clearly this wasn't a bug in xfs_logprint and the kernel was writing bad stuff to the log. First port of call was the buffer item formatting code, and the discontiguous memory/contiguous dirty region handling code immediately stood out. I've wondered for a long time why the code had this comment in it: vecp->i_addr = xfs_buf_offset(bp, buffer_offset); vecp->i_len = nbits * XFS_BLF_CHUNK; vecp->i_type = XLOG_REG_TYPE_BCHUNK; /* * You would think we need to bump the nvecs here too, but we do not * this number is used by recovery, and it gets confused by the boundary * split here * nvecs++; */ vecp++; And it didn't account for the extra vector pointer. The case being handled here is that a contiguous dirty region lies across a boundary that cannot be memcpy()d across, and so has to be split into two separate operations for xlog_write() to perform. What this code assumes is that what is written to the log is two consecutive blocks of data that are accounted in the buf log format item as the same contiguous dirty region and so will get decoded as such by the log recovery code. The thing is, xlog_write() knows nothing about this, and so just does it's normal thing of adding an opheader for each vector. That means the 8k region gets written to the log as two separate regions of 4k each, but because nvecs has not been incremented, the buf log format item accounts for only one of them. Hence when we come to log recovery, we process the first 4k region and then expect to come across a new item that starts with a log format structure of some kind that tells us whenteh next data is going to be. Instead, we hit raw buffer data and things go bad real quick. So, the commit from 2002 that commented out nvecs++ is just plain wrong. It breaks log recovery completely, and it would seem the only reason this hasn't been since then is that we don't log large contigous regions of multi-page unmapped buffers very often. Never would be a closer estimate, at least until the CRC code came along.... So, lets fix that by restoring the nvecs accounting for the extra region when we hit this case..... .... and there's the problemin log recovery it is apparently working around: XFS: Assertion failed: i == item->ri_total, file: fs/xfs/xfs_log_recover.c, line: 2135 Yup, xlog_recover_do_reg_buffer() doesn't handle contigous dirty regions being broken up into multiple regions by the log formatting code. That's an easy fix, though - if the number of contiguous dirty bits exceeds the length of the region being copied out of the log, only account for the number of dirty bits that region covers, and then loop again and copy more from the next region. It's a 2 line fix. Now xfstests xfs/085 passes, we have one less piece of mystery code, and one more important piece of knowledge about how to structure new log format items..

This, unfortunately in no longer so simple with CRC enabled filesystems as there is owner information embedded into the BMBT blocks that are swapped between inodes. Hence swapping the forks between inodes results in the inodes having mapping blocks that point to the wrong owner and hence are considered corrupt. To fix this we need an extent tree block or record based swap algorithm so that the BMBT block owner information can be updated atomically in the swap transaction.

The write verifier fires a corruption error indicating that the block number in the header is zero. This was being tripped by xfs/110. The problem is that the initialisation of the new block is done just fine in xfs_dir3_free_get_buf(), but the caller then users a dirv2 structure to zero on-disk header fields that xfs_dir3_free_get_buf() has already zeroed. These lined up with the block number in the dir v3 header format. While looking at this, I noticed that the struct xfs_dir3_free_hdr() had 4 bytes of padding in it that wasn't defined as padding or being zeroed by the initialisation. Add a pad field declaration and fully zero the on disk and in-core headers in xfs_dir3_free_get_buf() so that this is never an issue in the future. Note that this doesn't change the on-disk layout, just makes the 32 bits of padding in the layout explicit.

Otherwise we end up with zeros over the end of the attribute value when CRCs are enabled. While there, make sure we only ask to map an extent that covers the remaining range of the attribute, rather than asking every time for the full length of remote data. If the remote attribute blocks are contiguous with other parts of the attribute tree, it will map those blocks as well and we can potentially zero them incorrectly. We can also get buffer size mistmatches when trying to read or remove the remote attribute, and this can lead to not finding the correct buffer when looking it up in cache.

I assert that this is OK to do as CRCs are marked experimental and the first kernel it is included in has not yet reached release yet. Further, the userspace utilities are still evolving and so anyone using this stuff right now is a developer or tester using volatile filesystems for testing this feature. Hence changing the format right now to save longer term pain is the right thing to do. The fundamental change is to move from a header per extent in the attribute to a header per filesytem block in the attribute. This means there are more header blocks and the parsing of the attribute data is slightly more complex, but it has the advantage that we always know the size of the attribute on disk based on the length of the data it contains. This is where the header-per-extent method has problems. We don't know the size of the attribute on disk without first knowing how many extents are used to hold it. And we can't tell from a mapping lookup, either, because remote attributes can be allocated contiguously with other attribute blocks and so there is no obvious way of determining the actual size of the atribute on disk short of walking and mapping buffers. The problem with this approach is that if we map a buffer incorrectly (e.g. we make the last buffer for the attribute data too long), we then get buffer cache lookup failure when we map it correctly. i.e. we get a size mismatch on lookup. This is not necessarily fatal, but it's a cache coherency problem that can lead to returning the wrong data to userspace or writing the wrong data to disk. And debug kernels will assert fail if this occurs. I found lots of niggly little problems trying to fix this issue on a 4k block size filesystem, finally getting it to pass with lots of fixes. The thing is, 1024 byte filesystems still failed, and it was getting really complex handling all the corner cases that were showing up. And there were clearly more that I hadn't found yet. It is complex, fragile code, and if we don't fix it now, it will be complex, fragile code forever more. Hence the simple fix is to add a header to each filesystem block. This gives us the same relationship between the attribute data length and the number of blocks on disk as we have without CRCs - it's a linear mapping and doesn't require us to guess anything. It is simple to implement, too - the remote block count calculated at lookup time can be used by the remote attribute set/get/remove code without modification for both CRC and non-CRC filesystems. The world becomes sane again. Because the copy-in and copy-out now need to iterate over each filesystem block, I moved them into helper functions so we separate the block mapping and buffer manupulations from the attribute data and CRC header manipulations. The code becomes much clearer as a result, and it is a lot easier to understand and debug. It also appears to be much more robust - once it worked on 4k block size filesystems, it has worked without failure on 1k block size filesystems, too.

Once it has been the __thread_has_fpu() will start returning 0. Notice that with eagerfpu the __thread_has_fpu is always true initially. FPU use is thus always possible no matter what task is under us, unless the state has already been saved with kernel_fpu_begin().

This patch changes iscsit_free_cmd() to invoke __iscsit_free_cmd() before transport_generic_free_cmd() -> target_put_sess_cmd(), and also avoids aquiring the per-connection queue locks for typical fast-path calls during normal ISTATE_REMOVE operation. Also update iscsit_free_cmd() usage throughout iscsi-target to use the new 'bool shutdown' parameter.

The result is that the SCC interrupt sources become enabled (if they weren't already). This leads to an early boot crash (unexpected interrupt) given CONFIG_EARLY_PRINTK. Fix this by adding a delay. A successful reset disables the interrupt sources. Also, after the reset for channel A setup, the SCC then gets a second reset for channel B setup which leaves channel A uninitialised again. Fix this by performing the reset only once.

For 64 bit processes, disabled system register accesses are currently treated as unhandled instructions. This patch modifies entry.S to treat these unhandled traps as undefined instructions, sending a SIGILL to userspace.

As a result, the search returns the same item that the last cycle of the loop did and filldir() is called multiple times with the same data. The end result is that the buffer can contain the same name multiple times.

When the setuid bit is cleared during chown, ATTR_MODE and iattr->ia_mode are passed to all the xattrs as well. This means that the xattr directory will have S_IFREG added to its mode bits. This has been prevented in practice by a missing IS_PRIVATE check in reiserfs_acl_chmod, which caused a double-lock to occur while holding the write lock. Since the file system was completely locked up, the writeout of the corrupted mode never happened.

If one client deletes and recreates a file with timing such that the recreated file obtains the same [dirid, objectid] pair as the original file while another client accesses the file via file handle, the create and lookup can race and deadlock if the lookup manages to create the in-memory inode first. The create thread, in insert_inode_locked4, will hold the write lock while waiting on the other inode to be unlocked. The lookup thread, anywhere in the iget path, will release and reacquire the write lock while it schedules. If it needs to reacquire the lock while the create thread has it, it will never be able to make forward progress because it needs to reacquire the lock before ultimately unlocking the inode. This patch drops the write lock across the insert_inode_locked4 call so that the ordering of inode_wait -> write lock is retained. Since this would have been the case before the BKL push-down, this is safe.

Only if this bit is set, it should continue with the process of calling preempt_schedule_irq() to schedule highest priority task if available. Current code assumes that r8 contains TI_FLAGS and check this for _TIF_NEED_RESCHED, but as r8 is modified in the code which executes before this check, r8 no longer contains the expected TI_FLAGS information. As a result check for comparison with _TIF_NEED_RESCHED was failing even if NEED_RESCHED bit is set in the current thread_info flag. Due to this, preempt_schedule_irq() and in turn scheduler was not getting called even if highest priority task is ready for execution. So, store temporary results in r0 instead of r8 to prevent r8 from getting modified as subsequent code is dependent on its value.

H_IPOLL returns information about the priority and pending interrupts for a virtual cpu, without changing any state. H_XIRR_X is like H_XIRR in that it reads and acknowledges the highest-priority pending interrupt, but it also returns the timestamp (timebase register value) from when the interrupt was first received by the hypervisor.

Looking further, the mobility code in pseries is one of the call-sites which uses rtas_ibm_suspend_me(), which in turn calls rtas_cpu_state_change_mask(). And the mobility code is unconditionally compiled-in (it does not fall under any Kconfig option). And commit 120496ac (powerpc: Bring all threads online prior to migration/hibernation) which introduced this build regression is critical for the proper functioning of the migration code. So it appears that the only solution to this problem is to enable CONFIG_HOTPLUG_CPU if SMP is enabled on PPC_PSERIES platforms. So make that change in the Kconfig.

If so, it tests global and sync. In this case, sync=true, and it then checks if the address is already synced, and if so, returns 0. This 0 return causes __hw_addr_sync_one to increment the sync_cnt and refcount for the "from" list's address entry, even though the address is already synced and has a reference and sync_cnt. This will cause the sync_cnt and refcount to increment without bound every time an addresses is added to the "from" device and synced to the "to" device. The fix here has two parts: First, when __hw_addr_add_ex finds the address already exists and is synced, return -EEXIST instead of 0. Second, __hw_addr_sync_one checks the error return for -EEXIST, and if so, it (a) does not add a refcount/sync_cnt, and (b) returns 0 itself so that __hw_addr_sync_multiple will not return an error.

During the transition to the generic parser, the behavior of snd_hda_set_pin_ctl() was also changed to modify the cached values, too. And this caused a regression where the pin is still cleared even after the resume (including the resume from power save), resulting in the silent output. The fix is simply to replace snd_hda_set_pin_ctl() with the explicit call of snd_hda_codec_write() again.

And even worse score a SIGBUS when accessing gtt mmaps. The established ABI is that we _only_ return an -EIO from execbuf - all other ioctls should just work. And since the reset code moves all bos out of gpu domains and clears out all the last_seqno/ring tracking there really shouldn't be any reason for non-execbuf code to ever touch the hw and see an -EIO. After some extensive discussions we've noticed that these spurios -EIO are caused by i915_gem_wait_for_error: http://www.mail-archive.com/intel-gfx@lists.freedesktop.org/msg20540.html That is easy to fix by returning 0 instead of -EIO, since grabbing the dev->struct_mutex does not yet mean that we actually want to touch the hw. And so there is no reason at all to fail with -EIO. But that's not the entire since, since often (at least it's easily googleable) dmesg indicates that the reset fails and we declare the gpu wedged. Then, quite a bit later X wakes up with the "Timed out waiting for the gpu reset to complete" DRM_ERROR message in wait_for_errror and brings down the desktop with an -EIO/SIGBUS. So clearly we're missing a wakeup somewhere, since the gpu reset just doesn't take 10 seconds to complete. And indeed we're do handle the terminally wedged state wrong. Fix this all up.

Hence quirk the quirk. The problem is that crtc->active tracks the state of the entire display pipe, i.e. including planes, encoders and all. But our hw state readout simply looks at the pipe. But with the pipe A quirk we force-enable that (together with it's pll). To fix that mismatch we have two options: - Quirk the checked state to match what our sw tracking states if the pipe A quirk is in effect. - Improve the hw state readout to not get fooled by the pipe A quirk. Since we already have similar state clamping in e.g. assert_pipe I've opted for the first variant. Also note that we don't really loose any state checking: Individual pieces of the abstract crtc pipe are checked in the enable/disable functions with the various asssert_* checks we have, and the hw state check code doesn't check anything if the pipe is off anyway. v2: Pimp commit message after discussion with Chris and only apply the quirk for the quirk if we're checking pipe A. Otherwise we'll miss state checking for pipe B on i830M ... v3: Make the code comment consistent with the improved commit message, too (Chris).

Hence the following example: truncate --size=300 /mnt/file dd if=/mnt/file of=/dev/null iflag=direct led to FUSE_READ request of 300 bytes size. This turned out to be problem for userspace fuse implementations who rely on assumption that kernel fuse does not change alignment of request from client FS. The patch turns off the optimization if async_dio is disabled. And, if it's enabled, the patch fixes adjustment of number-of-bytes-to-read to preserve alignment. Note, that we cannot throw out short read optimization entirely because otherwise a direct read of a huge size issued on a tiny file would generate a huge amount of fuse requests and most of them would be ACKed by userspace with zero bytes read.

With some ASICs, though, the IRQ routine tries to access the GFX_INDEX ring causing a call to RREG32 with the value of -1 in radeon_fence_read. This, in turn causes the system to completely hang with some cards, requiring a hard reset. A call stack that can cause such a hang looks like this (using rv515 ASIC for the example here): * rv515_init (rv515.c) * radeon_irq_kms_init (radeon_irq_kms.c) * drm_irq_install (drm_irq.c) * radeon_driver_irq_preinstall_kms (radeon_irq_kms.c) * rs600_irq_process (rs600.c) * radeon_fence_process - due to SW interrupt (radeon_fence.c) * radeon_fence_read (radeon_fence.c) * hang due to RREG32(-1) The patch moves the IRQ installation to the card startup routine, after the ring has been initialized, but before the IRQ has been set. This fixes the issue, but requires a check to see if the IRQ is already installed, as is the case in the system resume codepath. I have tested the patch on three machines using the rv515, the rv770 and the evergreen ASIC. They worked without issues. This seems to be a known issue and has been reported on several bug tracking sites by various distributions (see links below). Most of reports recommend booting the system with KMS disabled and then enabling KMS by reloading the radeon module. For some reason, this was indeed a usable workaround, however, UMS is now deprecated and disabled by default.

The existing code assumes that 0x7f means no interrupt, but this value is an actually valid irq number, namely gpio bank 0's irq. This results in the driver not detecting when irq 0x7f is active which makes the machine effectively dead lock. This patch removes the interrupt poll loop and allows usage of gpio0 interrupt without an infinite loop.

When GFS2's directory management code allocates buffers for a directory hash table, if it can't get the memory it needs, it currently gives a bad return code. Rather than giving an error, this patch allows it to use virtual memory rather than kernel memory for the hash table. This should make it possible for directories to function properly, even when kernel memory becomes very fragmented.

Removing psmouse and inserting it back during the suspend/resume process is able to work around the issue, so the difference between psmouse_connect() and psmouse_reconnect() is the key to the root cause of this problem. After comparing the two different paths, synaptics driver has its own implementation of synaptics_reconnect(), and the missing psmouse_probe() seems significant, the patch below added psmouse_probe() to the reconnect process, and has been verified many times that the issue could not be reliably reproduced. There are two PS/2 commands in psmouse_probe(): 1. PSMOUSE_CMD_GETID 2. PSMOUSE_CMD_RESET_DIS Only the PSMOUSE_CMD_GETID seems to be significant. The PSMOUSE_CMD_RESET_DIS is irrelevant to this issue after trying several times. So we have only implemented this patch to issue the PSMOUSE_CMD_GETID so far.

Commit 057cf65 "bnx2x: Fix GSO for 57710/57711 chips" partially fixed this issue, but failed to set the correct IP checksum when receiving GSO packets via bridges, as such packets enter bnx2x_tx_split() and the FW flags needed to calculate IP checksum were erroneously set in the incorrect buffer descriptor.

The protocol selector bits are indicating IEEE 803.3u support and are fixed / read-only on some PHYs. Not setting them correctly on others (like TI DP83630) makes the PHY fall back to 10M HDX mode which should be avoided. Tested for TI DP83630 PHY on Microblaze platform.

Commit 5a1c0228 (cpufreq: Avoid calling cpufreq driver's target() routine if target_freq == policy->cur) caused a regression in this behavior. This fixes the regression by setting policy->cur based on the CPU's target frequency rather than the CPU's current reported frequency (which may be different). This means that the P-State will be set initially if the CPU's target frequency is different from the governor's target frequency. This fixes an issue where setting the default governor to performance wouldn't correctly enable turbo mode on all cores.

Therefore it doesn't make sense to match those ACPI device objects against a newly registered ACPI driver in acpi_bus_match(), so make that function return 0 if the device object passed to it has an ACPI scan handler attached. This also addresses a regression related to a broken ACPI table in the BIOS, where it has defined a _ROM method under the PCI root bridge object. This causes the video module to treat that object as a display controller device (since only display devices are supposed to have a _ROM method defined according to the ACPI spec). As a result, the ACPI video driver binds to the PCI root bridge object and overwrites the previously assigned driver_data field of it, causing subsequent calls to acpi_get_pci_dev() to fail.

This used phys_to_virt(), which is not valid for highmem addresses, and can cause a crash when booting a 32-bit kernel via the EFI boot stub. pcibios_add_device() assumes that the physical addresses stored in setup_data are accessible via the direct kernel mapping, and that calling phys_to_virt() is valid. This isn't guaranteed to be true on x86 where the direct mapping range is much smaller than on x86-64. Calling phys_to_virt() on a highmem address results in the following: BUG: unable to handle kernel paging request at 39a3c198 IP: [] pcibios_add_device+0x2f/0x90 ... Call Trace: [] pci_device_add+0xe3/0x130 [] pci_scan_single_device+0x8b/0xb0 [] pci_scan_slot+0x48/0x100 [] pci_scan_child_bus+0x24/0xc0 [] pci_acpi_scan_root+0x2c0/0x490 [] acpi_pci_root_add+0x312/0x42f ... The solution is to use ioremap() instead of phys_to_virt() to map the setup data into the kernel address space.

TLB fast mode relies on there being absolutely no concurrency; it frees pages first and invalidates TLBs later. However now we can get concurrency and stuff goes *bang*. This patch removes all tlb_fast_mode() code; it was found the better option vs trying to patch the hole by entangling tlb invalidation with the scheduler.

There are several places which manipulate dquots directly in the buffers, and they don't calculate CRCs appropriately, nor do they always set the buffer up to calculate CRCs appropriately. Firstly, if we log a dquot buffer (e.g. during allocation) it gets logged without valid CRC, and so on recovery we end up with a dquot that is not valid. Secondly, if we recover/repair a dquot, we don't have a verifier attached to the buffer and hence CRCs are not calculated on the way down to disk. Thirdly, calculating the CRC after we've changed the contents means that if we re-read the dquot from the buffer, we cannot verify the contents of the dquot are valid, as the CRC is invalid. So, to avoid all the dquot CRC errors that are being detected by the read verifier, change to using the same model as for inodes. That is, dquot CRCs are calculated and written to the backing buffer at the time the dquot is flushed to the backing buffer. If we modify the dquot directly in the backing buffer, calculate the CRC immediately after the modification is complete. Hence the dquot in the on-disk buffer should always have a valid CRC.

These all stem from the fact that inode alloc/unlink are logged in buffers, but all other inode changes are logged in inode items. Hence there are ordering constraints that recovery must follow to ensure the correct result occurs. As it turns out, this ordering has been working mostly by chance than good management. The existing code moves all buffers except cancelled buffers to the head of the list, and everything else to the tail of the list. The problem with this is that is interleaves inode items with the buffer cancellation items, and hence whether the inode item in an cancelled buffer gets replayed is essentially left to chance. Further, this ordering causes problems for log recovery when inode CRCs are enabled. It typically replays the inode unlink buffer long before it replays the inode core changes, and so the CRC recorded in an unlink buffer is going to be invalid and hence any attempt to validate the inode in the buffer is going to fail. Hence we really need to enforce the ordering that the inode alloc/unlink code has expected log recovery to have since inode chunk de-allocation was introduced back in 2003...

The trace buffer was saved along with various information about the task: comm, pid, uid, priority, etc. The uid is recorded with task_uid(tsk). But this is a macro that uses rcu_read_lock() to retrieve the data, and this happened to happen where RCU is blind (user_enter).

This fixes the RCU suspicious splat.

Incorrectly specified UART port results in system getting stalled while printing the message "Uncompressing Linux... done, booting the kernel" This UART port number is specified through S3C_LOWLEVEL_UART_PORT. Since the UART port might different for different board, it is not possible to specify it correctly for every board that use a common defconfig file. Calling this print subroutine only when DEBUG_LL fixes the problem. By disabling DEBUG_LL in default config file, we would be able to boot multiple boards with different default UART ports.
