[...] > > The only reason we migrate MSIs in interrupt context today is that there > wasn't infrastructure for support migration both in interrupt context > and outside of it. Yes. The idea here was to force the MSI migration to happen in process context. One of the patches in the series did disable_irq(dev->irq); irq_set_affinity(dev->irq, cpumask_of(dev->cpu)); enable_irq(dev->irq); with the above patch adding irq/manage code check for interrupt disabled and moving the interrupt in process context. IIRC, there was no IRQ_MOVE_PCNTXT when we were developing this HPET code and we ended up having this ugly hack. IRQ_MOVE_PCNTXT was there when we eventually submitted the patch upstream. But, looks like I did a blind rebasing instead of using IRQ_MOVE_PCNTXT in hpet MSI code. Below patch fixes this. i.e., revert commit 932775a4ab622e3c99bd59f14cc and add PCNTXT to HPET MSI setup. Also removes copying of desc->affinity in generic code as set_affinity routines are doing it internally. Reported-by: "Eric W. Biederman" Signed-off-by: Venkatesh Pallipadi Acked-by: "Eric W.

Instead we now have patches that solve this problem via static NUMA node mappings - not dynamic allocation and balancing. The patches are much simpler than this method but are still too large outside of the merge window, so we mark the dynamic balancer as broken for now, and queue up the new approach for v2.6.31.

This causes the mouse cursor or the scrolled page to jump. Included patch provides a workaround that discards mouse packets that are likely to contain bogus coordinates.

Between clear_used_math() and the state store on to the user stack, potentially we can get a page fault for the user address and can block. Infact, while testing we were hitting the might_fault() in __clear_user() which can do a schedule(). At a later point in time, we will schedule back into this process and resume the save state (using "xsave/fxsave" instruction) which can lead to DNA fault. And as used_math was cleared before, we will reinit the FP state in the DNA fault and continue. This reinit will result in loosing the FPU state of the process. Move clear_used_math() to a point after the FPU state has been stored onto the user stack. This issue is present from a long time (even before the xsave changes and the x86 merge). But it can easily be exposed in 2.6.28.x and 2.6.29.x series because of the __clear_user() in this path, which has an explicit __cond_resched() leading to a context switch with CONFIG_PREEMPT_VOLUNTARY.

The primary goal is to have better modeling if the hardware clocks and features with the aim of DVFS functionality. Highlights: - model PLLs and all PLL-derived clocks - model parent/child relationships of PLLs and clocks - convert to new clkdev layer - view clock frequency and refcount via /proc/davinci_clocks Special thanks to significant contributions and testing by David Brownell.

From now on, drivers should always use ioremap() instead of IO_ADDRESS(). In addition, remove the davinci_[read|write]* macros in favor of using ioremap.

Function omap_free_dma() sets the dev_id = -1 and then accesses the channel afterwards to clear it. But setting the dev_id=-1 makes the channel available for allocation again. So it is possible someone else can grab it and results are unpredictable. To avod this DMA channle is cleared first and then the dev_id = -1 is set. Thanks to McNeil, Sean for ointing out this issue.

Practical choices at this point are GPTIMER1 or GPTIMER12. Both of these timers are in the WKUP powerdomain, and so are unaffected by chip power management. GPTIMER1 can use sys_clk as a source, for applications where a high-resolution timer is more important than power management. GPTIMER12 has the special property that it has the secure 32kHz oscillator as its source clock, which may be less prone to glitches than the off-chip 32kHz oscillator. But on HS devices, it may not be available for Linux use. It appears that most boards are fine with GPTIMER1, but BeagleBoard should use GPTIMER12 when using a 32KiHz timer source, due to hardware bugs in revisions B4 and below. Modify board-omap3beagle.c to use GPTIMER12. This patch originally used a Kbuild config option to select the GPTIMER, but was changed to allow this to be specified in board-*.c files, per Tony's request. Kalle Vallo found a bug in an earlier version of this patch - thanks Kalle. Tested on Beagle rev B4 ES2.1, with and without CONFIG_OMAP_32K_TIMER, and 3430SDP.

By default for every 8 data block groups, we'll allocate 1 metadata chunk, or about 12% of the disk will be allocated for metadata. This can be changed by specifying the metadata_ratio mount option. This is simply the number of data block groups that have to be allocated to force a metadata chunk allocation. By making sure we allocate metadata chunks more often, we are less likely to get into situations where the whole disk has been allocated as data block groups.

This is what actually frees up any blocks replaced by COW, and anything the old blocks pointed to. Snapshot deletion will pause when a transaction commit has started, which helps to avoid a huge amount of delayed reference count updates piling up as the transaction is trying to close. But, this pause happens after the snapshot deletion process has asked other procs on the system to throttle back a bit so that it can make progress. We don't want to throttle everyone while we're waiting for the transaction commit, it leads to deadlocks in the user transaction ioctls used by Ceph and makes things slower in general. This patch changes things to avoid the throttling while we sleep.

The following patch adds a transfer of operating state from the real device to the VLAN device when the real device is administratively set up or down, and sets the carrier state up or down during init, open and close of the VLAN device. This permits observers above the VLAN device that care about the carrier state (bonding's link monitor, for example) to receive updates for administrative changes by more closely mimicing the behavior of real devices.

This patch is preparation for replacing all uses of ".head.text" or ".text.head" in the kernel with macros, so that the section name can later be changed without having to touch a lot of the kernel. Since some linker scripts do more complex things than referencing HEAD_TEXT, we add a HEAD_TEXT_SECTION macro that just contains the actual name. I've defined HEAD_TEXT_SECTION in a new header, include/linux/section-names.h, so that this section name only needs to appear in one place. I anticipate creating similar macro structures for a number of other section names. The long-term goal here is to be able to change the kernel's magic section names to those that are compatible with -ffunction-sections -fdata-sections. This requires renaming all magic sections with names of the form ".text.foo".

Overview + +Kernel CAPI operates as a dispatching layer between CAPI applications and CAPI +hardware drivers. Hardware drivers register ISDN devices (controllers, in CAPI +lingo) with Kernel CAPI to indicate their readiness to provide their service +to CAPI applications. CAPI applications also register with Kernel CAPI, +requesting association with a CAPI device. Kernel CAPI then dispatches the +application registration to an available device, forwarding it to the +corresponding hardware driver. Kernel CAPI then forwards CAPI messages in both +directions between the application and the hardware driver. + + +2. Driver and Device Registration + +CAPI drivers optionally register themselves with Kernel CAPI by calling the +Kernel CAPI function register_capi_driver() with a pointer to a struct +capi_driver. This structure must be filled with the name and revision of the +driver, and optionally a pointer to a callback function, add_card(). The +registration can be revoked by calling the function unregister_capi_driver() +with a pointer to the same struct capi_driver. + +CAPI drivers must register each of the ISDN devices they control with Kernel +CAPI by calling the Kernel CAPI function attach_capi_ctr() with a pointer to a +struct capi_ctr before they can be used. This structure must be filled with +the names of the driver and controller, and a number of callback function +pointers which are subsequently used by Kernel CAPI for communicating with the +driver. The registration can be revoked by calling the function +detach_capi_ctr() with a pointer to the same struct capi_ctr. + +Before the device can be actually used, the driver must fill in the device +information fields 'manu', 'version', 'profile' and 'serial' in the capi_ctr +structure of the device, and signal its readiness by calling capi_ctr_ready(). +From then on, Kernel CAPI may call the registered callback functions for the +device. + +If the device becomes unusable for any reason (shutdown, disconnect ...), the +driver has to call capi_ctr_reseted(). This will prevent further calls to the +callback functions by Kernel CAPI. + + +3. Application Registration and Communication + +Kernel CAPI forwards registration requests from applications (calls to CAPI +operation CAPI_REGISTER) to an appropriate hardware driver by calling its +register_appl() callback function. A unique Application ID (ApplID, u16) is +allocated by Kernel CAPI and passed to register_appl() along with the +parameter structure provided by the application. This is analogous to the +open() operation on regular files or character devices. + +After a successful return from register_appl(), CAPI messages from the +application may be passed to the driver for the device via calls to the +send_message() callback function. The CAPI message to send is stored in the +data portion of a skb. Conversely, the driver may call Kernel CAPI's +capi_ctr_handle_message() function to pass a received CAPI message to Kernel +CAPI for forwarding to an application, specifying its ApplID. + +Format and semantics of CAPI messages are specified in the CAPI 2.0 standard. + +Deregistration requests (CAPI operation CAPI_RELEASE) from applications are +forwarded as calls to the release_appl() callback function, passing the same +ApplID as with register_appl(). After return from release_appl(), no CAPI +messages for that application may be passed to or from the device anymore. + + +4. Data Structures + +4.1 struct capi_driver + +This structure describes a Kernel CAPI driver itself. It is used in the +register_capi_driver() and unregister_capi_driver() functions, and contains +the following non-private fields, all to be set by the driver before calling +register_capi_driver(): + +char name[32] + the name of the driver, as a zero terminated ASCII string +char revision[32] + the revision number of the driver, as a zero terminated ASCII string +int (*add_card)(struct capi_driver *driver, capicardparams *data) + a callback function pointer (may be NULL) + + +4.2 struct capi_ctr + +This structure describes an ISDN device (controller) handled by a Kernel CAPI +driver.

On a 128GB POWER6 box it ends up as 32MB: IP route cache hash table entries: 4194304 (order: 9, 33554432 bytes) It would be nice to cap this for memory consumption reasons, but a massive hashtable also causes a significant spike when measuring OS jitter. With a 32MB hashtable and 4 million entries, rt_worker_func is taking 5 ms to complete. On another system with more memory it's taking 14 ms. Even though rt_worker_func does call cond_sched() to limit its impact, in an HPC environment we want to keep all sources of OS jitter to a minimum. With the patch applied we limit the number of entries to 512k which can still be overriden by using the rt_entries boot option: IP route cache hash table entries: 524288 (order: 6, 4194304 bytes) With this patch rt_worker_func now takes 0.460 ms on the same system.

The response handler of the just started exchange config should wait for the completion by performing a down on this semaphore. Since this semaphore is still positive from the ERP enqueue the handler won't wait and therefore the exchange config will always fail leaving the adapter in error. The problem can be solved by performing the down on the semaphore before starting an ERP task. This is the logically correct order. Only walk the ERP loop if there is a task to perform.

The only reference to them is through any outstanding exchanges pending on the rogue ports. If the module is removed while a retry is set on a rogue port (say a Plogi retry for instance), this retry is not cancelled because there is no reference to the rogue port in the discovery rports list. Thus the local port can clean itself up, delete the exchange pool, and then the rogue port timeout can fire and try to start up another exchange. This patch tracks the rogue ports in a new list disc->rogue_rports. Creating a new list instead of using the disc->rports list keeps remote port code change to a minimum. 1) Whenever a rogue port is created, it is immediately added to the disc->rogue_rports list. 2) When the rogues port goes to ready, it is removed from the rogue list and the real remote port is added to the disc->rports list 3) The removal of the rogue from the disc->rogue_rports list is done in the context of the fc_rport_work() workQ thread in discovery callback. 4) Real rports are removed from the disc->rports list like before. Lookup is done only in the real rports list. This avoids making large changes to the remote port code. 5) In fc_disc_stop_rports, the rogues list is traversed in addition to the real list to stop the rogue ports and issue logoffs on them. This way, rogue ports get cleaned up when the local port goes away. 6) rogue remote ports are not removed from the list right away, but removed late in fc_rport_work() context, multiple threads can find the same remote port in the list and call rport_logoff(). Rport_logoff() only continues with the logoff if port is not in NONE state, thus preventing multiple logoffs and multiple list deletions. 7) Since the rport is removed from the disc list at a later stage (in the disc callback), incoming frames can find the rport even if rport_logoff() has been called on the rport. When rport_logoff() is called, the rport state is set to NONE, and we are trying to cancel all exchanges and retries on that port. While in this state, if an incoming Plogi/Prli/Logo or other frames match the rport, we should not reply because the rport is in the NONE state. Just drop the frame, since the rport will be deleted soon in the disc callback (fc_rport_work) 8) In fc_disc_single(), remove rport lookup and call to fc_disc_del_target. fc_disc_single() is called from recv_rscn_req() where rport lookup and rport_logoff is already done.

In OSD2r01-r04 it was aligned on 2 bytes. (This is because in OSD2r01 the complete element was 8 bytes padded at end but the header was not adjusted and caused permanent miss-alignment.) OSD1 elements are not padded and might be or might not be aligned. OSD1 is still supported.

So for example on dm6467, GPIO-42 is the last GPIO, and trying to use GPIO-43 now fails cleanly; or GPIO-72 on dm6446. - Enable GPIO interrupts on each 16-bit GPIO-irq bank ... previously, only the first five were enabled, so GPIO-80 and above (on dm355) wouldn't trigger IRQs. - Use the right IRQ for each GPIO bank. The wrong values were used for dm355 chips, so GPIO IRQs got routed incorrectly. - Handle up to four pairs of 16-bit GPIO banks ... previously only three were handled, so accessing GPIO-96 and up (e.g. on dm355) would oops. - Update several comments that were dm6446-specific. Verified by receiving GPIO-1 (dm9000) and GPIO-5 (msp430) IRQs on the DM355 EVM. One thing this doesn't do is handle the way some of the GPIO numbers on dm6467 are reserved but aren't valid as GPIOs. Some bitmap logic could fix that if needed.

The compatibilities are a bit different based on which kernel was used previously + Users of TI/MV kernels no longer see mtd2 "params" (mainline u-boot env is in a different place) * Filesystem is now mtd2 ... vs mtd3 + Users of GIT kernels now see mtd0 and mtd1 partitions * Filesystem partition starts 640 KBytes earlier * Filesystem is now mtd2 ... vs mtd0 * Linux now *uses* the flash-resident BBT * Removes annoying slowdown/hiccup during boot * Potentially ~64KB less space available with TI/MV kernels If you *used* NAND partitions from Linux, there is no solution that's fully compatible with all previous kernels in those respects ... ergo this "best compromise". It'd be good to back back up the filesystem data; or, carry your own backwards-compatibility patch for awhile.

This meant the common case of no acls resulted in expensive btree searches every time the kernel checked permissions (which is quite often). This is a modified version of Linus' original patch: Properly set initial acl fields to BTRFS_ACL_NOT_CACHED in the inode. This forces an acl lookup when permission checks are done. Fix btrfs_get_acl to avoid lookups and locking when the inode acls fields are set to null. Fix btrfs_get_acl to use the right return value from __btrfs_getxattr when deciding to cache a NULL acl. It was storing a NULL acl when __btrfs_getxattr return -ENOENT, but __btrfs_getxattr was actually returning -ENODATA for this case.

This unfortunatly added a penalty when a frame is transmitted, since we have at TX completion time to call sock_wfree() to perform necessary memory accounting. This calls sock_def_write_space() and utimately scheduler if any thread is waiting on the socket. Thread(s) waiting for an incoming frame was scheduled, then had to sleep again as event was meaningless. (All threads waiting on a socket are using same sk_sleep anchor) This adds lot of extra wakeups and increases latencies, as noted by Christoph Lameter, and slows down softirq handler. Reference : http://marc.info/?l=linux-netdev&m=124060437012283&w=2 Fortunatly, Davide Libenzi recently added concept of keyed wakeups into kernel, and particularly for sockets (see commit 37e5540b3c9d838eb20f2ca8ea2eb8072271e403 epoll keyed wakeups: make sockets use keyed wakeups) Davide goal was to optimize epoll, but this new wakeup infrastructure can help non epoll users as well, if they care to setup an appropriate handler. This patch introduces new DEFINE_WAIT_FUNC() helper and uses it in wait_for_packet(), so that only relevant event can wakeup a thread blocked in this function.

The problem part is the dedicated pairing when using Legacy Pairing (Bluetooth 2.0 and before). At that point no user is present and pairing attempts will be disconnected within 10 seconds or less. In previous kernel version this was not a problem since the disconnect timeout wasn't triggered on incoming connections for the first time. However this caused issues with broken host stacks that kept the connections around after dedicated pairing. When the support for Simple Pairing got added, the link establishment procedure needed to be changed and now causes issues when using Legacy Pairing When using Simple Pairing it is possible to do a proper reference counting of ACL link users. With Legacy Pairing this is not possible since the specification is unclear in some areas and too many broken Bluetooth devices have already been deployed. So instead of trying to deal with all the broken devices, a special pairing timeout will be introduced that increases the timeout to 60 seconds when pairing is triggered. If a broken devices now puts the stack into an unforeseen state, the worst that happens is the disconnect timeout triggers after 120 seconds instead of 4 seconds. This allows successful pairings with legacy and broken devices now.

With the usage of Simple Pairing it is required that all connections (except the ones for SDP) are encrypted. So even the low security requirement mandates an encrypted connection when using Simple Pairing. When using Legacy Pairing (for Bluetooth 2.0 devices and older) this is not required since it causes interoperability issues. To support this properly the low security requirement translates into different host controller transactions depending if Simple Pairing is supported or not. However in case of Simple Pairing the command to switch on encryption after a successful authentication is not triggered for the low security mode. This patch fixes this and actually makes the logic to differentiate between Simple Pairing and Legacy Pairing a lot simpler.

This patch adds a multi-touch (MT) protocol which allows drivers to report details for an arbitrary number of fingers. The driver sends a SYN_MT_REPORT event via the input_mt_sync() function when a complete finger has been reported. In order to stay compatible with existing applications, the data reported in a finger packet must not be recognized as single-touch events. In addition, all finger data must bypass input filtering, since subsequent events of the same type refer to different fingers. A set of ABS_MT events with the desired properties are defined. The events are divided into categories, to allow for partial implementation. The minimum set consists of ABS_MT_TOUCH_MAJOR, ABS_MT_POSITION_X and ABS_MT_POSITION_Y, which allows for multiple fingers to be tracked. If the device supports it, the ABS_MT_WIDTH_MAJOR may be used to provide the size of the approaching finger. Anisotropy and direction may be specified with ABS_MT_TOUCH_MINOR, ABS_MT_WIDTH_MINOR and ABS_MT_ORIENTATION. Devices with more granular information may specify general shapes as blobs, i.e., as a sequence of rectangular shapes grouped together by a ABS_MT_BLOB_ID. Finally, the ABS_MT_TOOL_TYPE may be used to specify whether the touching tool is a finger or a pen.

On older kernels there was a reader/writer lock per table which was a performance bottleneck. In 2.6.30-rc, this was converted to use RCU and the counters/rules which solved the performance problems for do_table but made replacing rules much slower because of the necessary RCU grace period. This version uses a per-cpu set of spinlocks and counters to allow to table processing to proceed without the cache thrashing of a global reader lock and keeps the same performance for table updates.

It would not read the eeprom. After some bisects, I realized this has been like that since forever (at least 2.6.18). The problem is that shutdown is doing the same thing that suspend does and puts the device in D3 state. I couldn't find a way to get the device back to a sane state in the probe function.

This breaks static build of video4linux drivers, that use generic CPU i2c adapter drivers and the v4l2-subdev subsystem, because during video4linux probing the v4l2-subdev core requires a struct i2c_adapter context, which cannot be satisfied before the i2c subsystem is initialised. Moving drivers/media after drivers/i2c fixes this problem.

This has been reported via bugzilla a while ago (#717) and has recently also shown up via lockdep. So allocate a temporary buffer to format the kernel getbmap structures into and then copy them out after dropping the locks. A little problem with this is that we limit the number of extents we can copy out by the maximum allocation size, but I see no real way around that.

This document +describes the multi-touch (MT) protocol which allows kernel drivers to +report details for an arbitrary number of fingers. + + +Usage +----- + +Anonymous finger details are sent sequentially as separate packets of ABS +events. Only the ABS_MT events are recognized as part of a finger +packet. The end of a packet is marked by calling the input_mt_sync() +function, which generates a SYN_MT_REPORT event. The end of multi-touch +transfer is marked by calling the usual input_sync() function. + +A set of ABS_MT events with the desired properties is defined. The events +are divided into categories, to allow for partial implementation. The +minimum set consists of ABS_MT_TOUCH_MAJOR, ABS_MT_POSITION_X and +ABS_MT_POSITION_Y, which allows for multiple fingers to be tracked. If the +device supports it, the ABS_MT_WIDTH_MAJOR may be used to provide the size +of the approaching finger. Anisotropy and direction may be specified with +ABS_MT_TOUCH_MINOR, ABS_MT_WIDTH_MINOR and ABS_MT_ORIENTATION. Devices with +more granular information may specify general shapes as blobs, i.e., as a +sequence of rectangular shapes grouped together by an +ABS_MT_BLOB_ID. Finally, the ABS_MT_TOOL_TYPE may be used to specify +whether the touching tool is a finger or a pen or something else. + + +Event Semantics +--------------- + +The word "contact" is used to describe a tool which is in direct contact +with the surface. A finger, a pen or a rubber all classify as contacts. + +ABS_MT_TOUCH_MAJOR + +The length of the major axis of the contact. The length should be given in +surface units. If the surface has an X times Y resolution, the largest +possible value of ABS_MT_TOUCH_MAJOR is sqrt(X^2 + Y^2), the diagonal. + +ABS_MT_TOUCH_MINOR + +The length, in surface units, of the minor axis of the contact. If the +contact is circular, this event can be omitted. + +ABS_MT_WIDTH_MAJOR + +The length, in surface units, of the major axis of the approaching +tool. This should be understood as the size of the tool itself. The +orientation of the contact and the approaching tool are assumed to be the +same. + +ABS_MT_WIDTH_MINOR + +The length, in surface units, of the minor axis of the approaching +tool. Omit if circular. + +The above four values can be used to derive additional information about +the contact. The ratio ABS_MT_TOUCH_MAJOR / ABS_MT_WIDTH_MAJOR approximates +the notion of pressure. The fingers of the hand and the palm all have +different characteristic widths [1]. + +ABS_MT_ORIENTATION + +The orientation of the ellipse. The value should describe half a revolution +clockwise around the touch center. The scale of the value is arbitrary, but +zero should be returned for an ellipse aligned along the Y axis of the +surface. As an example, an index finger placed straight onto the axis could +return zero orientation, something negative when twisted to the left, and +something positive when twisted to the right. This value can be omitted if +the touching object is circular, or if the information is not available in +the kernel driver. + +ABS_MT_POSITION_X + +The surface X coordinate of the center of the touching ellipse. + +ABS_MT_POSITION_Y + +The surface Y coordinate of the center of the touching ellipse. + +ABS_MT_TOOL_TYPE + +The type of approaching tool. A lot of kernel drivers cannot distinguish +between different tool types, such as a finger or a pen. In such cases, the +event should be omitted. The protocol currently supports MT_TOOL_FINGER and +MT_TOOL_PEN [2]. + +ABS_MT_BLOB_ID + +The BLOB_ID groups several packets together into one arbitrarily shaped +contact. This is a low-level anonymous grouping, and should not be confused +with the high-level contactID, explained below. Most kernel drivers will +not have this capability, and can safely omit the event. + + +Finger Tracking +--------------- + +The kernel driver should generate an arbitrary enumeration of the set of +anonymous contacts currently on the surface. The order in which the packets +appear in the event stream is not important. + +The process of finger tracking, i.e., to assign a unique contactID to each +initiated contact on the surface, is left to user space; preferably the +multi-touch X driver [3]. In that driver, the contactID stays the same and +unique until the contact vanishes (when the finger leaves the surface). The +problem of assigning a set of anonymous fingers to a set of identified +fingers is a euclidian bipartite matching problem at each event update, and +relies on a sufficiently rapid update rate. + +Notes +----- + +In order to stay compatible with existing applications, the data +reported in a finger packet must not be recognized as single-touch +events. In addition, all finger data must bypass input filtering, +since subsequent events of the same type refer to different fingers. + +The first kernel driver to utilize the MT protocol is the bcm5974 driver, +where examples can be found. + +[1] With the extension ABS_MT_APPROACH_X and ABS_MT_APPROACH_Y, the +difference between the contact position and the approaching tool position +could be used to derive tilt. +[2] The list can of course be extended. +[3] The multi-touch X driver is currently in the prototyping stage. At the +time of writing (April 2009), the MT protocol is not yet merged, and the +prototype implements finger matching, basic mouse support and two-finger +scrolling. The project aims at improving the quality of current multi-touch +functionality available in the synaptics X driver, and in addition +implement more advanced gestures. -- cgit v0.10.2 From 9cba3ccc8fe77b67aff2db8f5827d7cb752ce11f Mon Sep 17 00:00:00 2001 From: Catalin Marinas Date: Thu, 30 Apr 2009 17:06:03 +0100 Subject: [ARM] 5488/1: ARM errata: Invalidation of the Instruction Cache operation can fail This patch implements the recommended workaround for erratum 411920 (ARM1136, ARM1156, ARM1176).

We then have read_markers() mmap'ing the file, and writer_markers() opening that same file for writing. The issue is that read_markers() exits without munmap'ing the file and is as a matter holding a reference on Modules.markers. When write_markers() is opening that very same file for writing, we still have a reference on it and cygwin (Windows?) is then making fopen() fail with EPERM. Calling release_file() before exiting read_markers() clears that reference (and memory leak) and fopen() then succeeds. Tested on both cygwin (1.3.22) and Linux.

But this heuristic has two problems: it will miss a bad section that has no relocations, and it will incorrectly flag many gcc-generated sections as bad when compiling with -ffunction-sections -fdata-sections. On mips it fixes a lot of bogus warnings with gcc 4.4.0 lije this one: WARNING: crypto/cryptd.o (.text.T.349): unexpected section name. So instead of checking whether the section name matches a particular pattern, we directly check for a missing SHF_ALLOC in the section flags.

This allows the filesystem to have full control of page dirtying events coming from the VM. Rather than simply hold the page locked over the page_mkwrite call, we call page_mkwrite with the page unlocked and allow callers to return with it locked, so filesystems can avoid LOR conditions with page lock. The problem with the current scheme is this: a filesystem that wants to associate some metadata with a page as long as the page is dirty, will perform this manipulation in its ->page_mkwrite. It currently then must return with the page unlocked and may not hold any other locks (according to existing page_mkwrite convention). In this window, the VM could write out the page, clearing page-dirty. The filesystem has no good way to detect that a dirty pte is about to be attached, so it will happily write out the page, at which point, the filesystem may manipulate the metadata to reflect that the page is no longer dirty. It is not always possible to perform the required metadata manipulation in ->set_page_dirty, because that function cannot block or fail. The filesystem may need to allocate some data structure, for example. And the VM cannot mark the pte dirty before page_mkwrite, because page_mkwrite is allowed to fail, so we must not allow any window where the page could be written to if page_mkwrite does fail. This solution of holding the page locked over the 3 critical operations (page_mkwrite, setting the pte dirty, and finally setting the page dirty) closes out races nicely, preventing page cleaning for writeout being initiated in that window. This provides the filesystem with a strong synchronisation against the VM here. - Sage needs this race closed for ceph filesystem. - Trond for NFS (http://bugzilla.kernel.org/show_bug.cgi?id=12913). - I need it for fsblock. - I suspect other filesystems may need it too (eg. btrfs). - I have converted buffer.c to the new locking. Even simple block allocation under dirty pages might be susceptible to i_size changing under partial page at the end of file (we also have a buffer.c-side problem here, but it cannot be fixed properly without this patch). - Other filesystems (eg. NFS, maybe btrfs) will need to change their page_mkwrite functions themselves. [ This also moves page_mkwrite another step closer to fault, which should eventually allow page_mkwrite to be moved into ->fault, and thus avoiding a filesystem calldown and page lock/unlock cycle in __do_fault. ] [akpm@linux-foundation.org: fix derefs of NULL ->mapping] Cc: Sage Weil Cc: Trond Myklebust Signed-off-by: Nick Piggin Cc: Valdis Kletnieks Cc: Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds diff --git a/Documentation/filesystems/Locking b/Documentation/filesystems/Locking index 76efe5b..3120f8d 100644 --- a/Documentation/filesystems/Locking +++ b/Documentation/filesystems/Locking @@ -512,16 +512,24 @@ locking rules: BKL mmap_sem PageLocked(page) open: no yes close: no yes -fault: no yes -page_mkwrite: no yes no +fault: no yes can return with page locked +page_mkwrite: no yes can return with page locked access: no yes - ->page_mkwrite() is called when a previously read-only page is -about to become writeable.

Considering hierarchy, shrinking has to be done from the mem_over_limit, not from the memcg which the page would be charged to. mem_cgroup_try_charge_swapin() does all of these things properly, so we use it and call cancel_charge_swapin when it succeeded.

That happens because aout binary handler gets on the top of the binfmt list due to late registration, and kernel attempts to execute the binary without preparatory work that must be done by binfmt_loader. Fixed by changing the registration order of the default binfmt handlers using list_add_tail() and introducing insert_binfmt() function which places new handler on the top of the binfmt list. This might be generally useful for installing arch-specific frontends for default handlers or just for overriding them.

But NR_CPUS proportional isn't good calculation. In general, possibility of lock contention is proportional to the number of online cpus, not theorical maximum cpus (NR_CPUS). The current kernel has generic percpu-counter stuff. using it is right way. it makes code simplify and percpu_counter_read_positive() don't make underflow issue.

On systems without OF, this comes from a flattened device tree blob. This blob is usually generated by dtc, a tool which compiles a text description of the device tree into the flattened format used by the kernel. Sometimes, the bootwrapper makes small changes to the pre-compiled device tree blob (e.g. filling in the size of RAM). To do this it uses the libfdt library. Because these are only used on powerpc, the code for both these tools is included under arch/powerpc/boot (these were imported and are periodically updated from the upstream dtc tree). However, the microblaze architecture, currently being prepared for merging to mainline also uses dtc to produce device tree blobs. A few other archs have also mentioned some interest in using dtc. Therefore, this patch moves dtc and libfdt from arch/powerpc into scripts, where it can be used by any architecture. The vast bulk of this patch is a literal move, the rest is adjusting the various Makefiles to use dtc and libfdt correctly from their new locations.
