| | * xfs: check for more work before sleeping in xfssyncdDave Chinner2010-04-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 20f6b2c785cf187445f126321638ab8ba7aa7494 upstream. xfssyncd processes a queue of work by detaching the queue and then iterating over all the work items. It then sleeps for a time period or until new work comes in. If new work is queued while xfssyncd is actively processing the detached work queue, it will not process that new work until after a sleep timeout or the next work event queued wakes it. Fix this by checking the work queue again before going to sleep.

| | * xfs: fix locking for inode cache radix tree tag updatesChristoph Hellwig2010-04-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit f1f724e4b523d444c5a598d74505aefa3d6844d2 upstream. The radix-tree code requires it's users to serialize tag updates against other updates to the tree. While XFS protects tag updates against each other it does not serialize them against updates of the tree contents, which can lead to tag corruption. Fix the inode cache to always take pag_ici_lock in exclusive mode when updating radix tree tags.

| | * xfs: Non-blocking inode locking in IO completionDave Chinner2010-04-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 77d7a0c2eeb285c9069e15396703d0cb9690ac50 upstream. The introduction of barriers to loop devices has created a new IO order completion dependency that XFS does not handle. The loop device implements barriers using fsync and so turns a log IO in the XFS filesystem on the loop device into a data IO in the backing filesystem. That is, the completion of log IOs in the loop filesystem are now dependent on completion of data IO in the backing filesystem. This can cause deadlocks when a flush daemon issues a log force with an inode locked because the IO completion of IO on the inode is blocked by the inode lock. This in turn prevents further data IO completion from occuring on all XFS filesystems on that CPU (due to the shared nature of the completion queues). This then prevents the log IO from completing because the log is waiting for data IO completion as well. The fix for this new completion order dependency issue is to make the IO completion inode locking non-blocking. If the inode lock can't be grabbed, simply requeue the IO completion back to the work queue so that it can be processed later. This prevents the completion queue from being blocked and allows data IO completion on other inodes to proceed, hence avoiding completion order dependent deadlocks.

| | * iwlwifi: fix scan raceReinette Chatre2010-04-26

There is a problem if an "internal short scan" is in progress when a mac80211 requested scan arrives. If this new scan request arrives within the "next_scan_jiffies" period then driver will immediately return success and complete the scan. The problem here is that the scan has not been fully initialized at this time (is_internal_short_scan is still set to true because of the currently running scan), which results in the scan completion never to be sent to mac80211. At this time also, evan though the internal short scan is still running the state (is_internal_short_scan) will be set to false, so when the internal scan does complete then mac80211 will receive a scan completion. Fix this by checking right away if a scan is in progress when a scan request arrives from mac80211.

| | * ecryptfs: fix use with tmpfs by removing d_drop from ecryptfs_destroy_inodeJeff Mahoney2010-04-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 133b8f9d632cc23715c6d72d1c5ac449e054a12a upstream. Since tmpfs has no persistent storage, it pins all its dentries in memory so they have d_count=1 when other file systems would have d_count=0. ->lookup is only used to create new dentries. If the caller doesn't instantiate it, it's freed immediately at dput(). ->readdir reads directly from the dcache and depends on the dentries being hashed. When an ecryptfs mount is mounted, it associates the lower file and dentry with the ecryptfs files as they're accessed. When it's umounted and destroys all the in-memory ecryptfs inodes, it fput's the lower_files and d_drop's the lower_dentries. Commit 4981e081 added this and a d_delete in 2008 and several months later commit caeeeecf removed the d_delete. I believe the d_drop() needs to be removed as well. The d_drop effectively hides any file that has been accessed via ecryptfs from the underlying tmpfs since it depends on it being hashed for it to be accessible. I've removed the d_drop on my development node and see no ill effects with basic testing on both tmpfs and persistent storage. As a side effect, after ecryptfs d_drops the dentries on tmpfs, tmpfs BUGs on umount. This is due to the dentries being unhashed. tmpfs->kill_sb is kill_litter_super which calls d_genocide to drop the reference pinning the dentry. It skips unhashed and negative dentries, but shrink_dcache_for_umount_subtree doesn't. Since those dentries still have an elevated d_count, we get a BUG(). This patch removes the d_drop call and fixes both issues.

| | * ALSA: hda - Add position_fix quirk for Biostar moboTakashi Iwai2010-04-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 8815cd030fdd73932a791d1f06194c8db807cde7 upstream. The Biostar mobo seems to give a wrong DMA position, resulting in stuttering or skipping sounds on 2.6.34. Since the commit 7b3a177b0d4f92b3431b8dca777313a07533a710, "ALSA: pcm_lib: fix "something must be really wrong" condition", makes the position check more strictly, the DMA position problem is revealed more clearly now. The fix is to use only LPIB for obtaining the position, i.e. passing position_fix=1. This patch adds a static quirk to achieve it as default.

This makes the b43 driver just automatically fall back to PIO mode when DMA doesn't work. The driver already told the user to do it, so rather than have the user reload the module with a new flag, just make the driver do it automatically. We keep the message as an indication that something is wrong, but now just automatically fall back to the hopefully working PIO case.

This patch removes this option and allows PIO mode to be selected with a load-time parameter for the module. Note that the configuration variable CONFIG_B43_PIO is also removed. Once the DMA problem with the BCM4312 devices is solved, this patch will likely be reverted.

The IPoIB UD QP reports send completions to priv->send_cq, which is usually left unarmed; it only gets armed when the number of outstanding send requests reaches the size of the TX queue. This arming is done only in the send path for the UD QP. However, when sending CM packets, the net queue may be stopped for the same reasons but no measures are taken to recover the UD path from a lockup. Consider this scenario: a host sends high rate of both CM and UD packets, with a TX queue length of N. If at some time the number of outstanding UD packets is more than N/2 and the overall outstanding packets is N-1, and CM sends a packet (making the number of outstanding sends equal N), the TX queue will be stopped. When all the CM packets complete, the number of outstanding packets will still be higher than N/2 so the TX queue will not be restarted. Fix this by calling ib_req_notify_cq() when the queue is stopped in the CM path.

While investigating a bug, I came across a possible bug in v9fs. The problem is similar to the one reported for NFS by ASANO Masahiro in http://lkml.org/lkml/2005/12/21/334. v9fs_file_lock() will skip locks on file which has mode set to 02666. This is a problem in cases where the mode of the file is changed after a process has obtained a lock on the file. Such a lock will be skipped during unlock and the machine will end up with a BUG in locks_remove_flock(). v9fs_file_lock() should skip the check for mandatory locks when unlocking a file.

In ocfs2_validate_gd_parent, we check bg_chain against the cl_next_free_rec of the dinode. Actually in resize, we have the chance of bg_chain == cl_next_free_rec. So add some additional condition check for it. I also rename paramter "clean_error" to "resize", since the old one is not clearly enough to indicate that we should only meet with this case in resize. btw, the correpsonding bug is http://oss.oracle.com/bugzilla/show_bug.cgi?id=1230.

Thus, acls were some times not getting propagated between nodes. This patch fixes the issue by adding a helper function ocfs2_acl_set_mode() which does this the right way. ocfs2_set_acl() and ocfs2_init_acl() are then updated to call ocfs2_acl_set_mode().

The Intel Architecture Optimization Reference Manual states that a short load that follows a long store to the same object will suffer a store forwading penalty, particularly if the two accesses use different addresses. Trivially, a long load that follows a short store will also suffer a penalty. __downgrade_write() in rwsem incurs both penalties: the increment operation will not be able to reuse a recently-loaded rwsem value, and its result will not be reused by any recently-following rwsem operation. A comment in the code states that this is because 64-bit immediates are special and expensive; but while they are slightly special (only a single instruction allows them), they aren't expensive: a test shows that two loops, one loading a 32-bit immediate and one loading a 64-bit immediate, both take 1.5 cycles per iteration. Fix this by changing __downgrade_write to use the same add instruction on i386 and on x86_64, so that it uses the same operand size as all the other rwsem functions.

This one is much faster than the spinlock based fallback rwsem code, with certain artifical benchmarks having shown 300%+ improvement on threaded page faults etc. Again, note the 32767-thread limit here. So this really does need that whole "make rwsem_count_t be 64-bit and fix the BIAS values to match" extension on top of it, but that is conceptually a totally independent issue. NOT TESTED! The original patch that this all was based on were tested by KAMEZAWA Hiroyuki, but maybe I screwed up something when I created the cleaned-up series, so caveat emptor.. Also note that it _may_ be a good idea to mark some more registers clobbered on x86-64 in the inline asms instead of saving/restoring them. They are inline functions, but they are only used in places where there are not a lot of live registers _anyway_, so doing for example the clobbers of %r8-%r11 in the asm wouldn't make the fast-path code any worse, and would make the slow-path code smaller. (Not that the slow-path really matters to that degree. Saving a few unnecessary registers is the _least_ of our problems when we hit the slow path. The instruction/cycle counting really only matters in the fast path).

For x86-64, 32767 threads really is not enough. Change rwsem_count_t to a signed long, so that it is 64 bits on x86-64. This required the following changes to the assembly code: a) %z0 doesn't work on all versions of gcc! At least gcc 4.4.2 as shipped with Fedora 12 emits "ll" not "q" for 64 bits, even for integer operands. Newer gccs apparently do this correctly, but avoid this problem by using the _ASM_ macros instead of %z. b) 64 bits immediates are only allowed in "movq $imm,%reg" constructs... no others. Change some of the constraints to "e", and fix the one case where we would have had to use an invalid immediate -- in that case, we only care about the upper half anyway, so just access the upper half.

| | * x86: clean up rwsem type systemLinus Torvalds2010-04-26

The fast version of the rwsems (the code that uses xadd) has traditionally only worked on x86-32, and as a result it mixes different kinds of types wildly - they just all happen to be 32-bit. We have "long", we have "__s32", and we have "int". To make it work on x86-64, the types suddenly matter a lot more. It can be either a 32-bit or 64-bit signed type, and both work (with the caveat that a 32-bit counter will only have 15 bits of effective write counters, so it's limited to 32767 users). But whatever type you choose, it needs to be used consistently. This makes a new 'rwsem_counter_t', that is a 32-bit signed type. For a 64-bit type, you'd need to also update the BIAS values.

| | * x86-32: clean up rwsem inline asm statementsLinus Torvalds2010-04-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 59c33fa7791e9948ba467c2b83e307a0d087ab49 upstream. This makes gcc use the right register names and instruction operand sizes automatically for the rwsem inline asm statements. So instead of using "(%%eax)" to specify the memory address that is the semaphore, we use "(%1)" or similar. And instead of forcing the operation to always be 32-bit, we use "%z0", taking the size from the actual semaphore data structure itself. This doesn't actually matter on x86-32, but if we want to use the same inline asm for x86-64, we'll need to have the compiler generate the proper 64-bit names for the registers (%rax instead of %eax), and if we want to use a 64-bit counter too (in order to avoid the 15-bit limit on the write counter that limits concurrent users to 32767 threads), we'll need to be able to generate instructions with "q" accesses rather than "l". Since this header currently isn't enabled on x86-64, none of that matters, but we do want to use the xadd version of the semaphores rather than have to take spinlocks to do a rwsem. The mm->mmap_sem can be heavily contended when you have lots of threads all taking page faults, and the fallback rwsem code that uses a spinlock performs abysmally badly in that case.

Hit another kdump problem as reported by Neil Horman. When initializaing the IOMMU, we attach devices to their domains before the IOMMU is fully (re)initialized. Attaching a device will issue some important invalidations. In the context of the newly kexec'd kdump kernel, the IOMMU may have stale cached data from the original kernel. Because we do the attach too early, the invalidation commands are placed in the new command buffer before the IOMMU is updated w/ that buffer. This leaves the stale entries in the kdump context and can renders device unusable. Simply enable the IOMMU before we do the attach.

For example, I see this upon rebinding: AMD-Vi: Event logged [IO_PAGE_FAULT device=02:00.0 domain=0x0000 address=0x000000007e2a8000 flags=0x0050] AMD-Vi: Event logged [IO_PAGE_FAULT device=02:00.0 domain=0x0000 address=0x000000007e2a8040 flags=0x0050] AMD-Vi: Event logged [IO_PAGE_FAULT device=02:00.0 domain=0x0000 address=0x000000007e2a8080 flags=0x0050] AMD-Vi: Event logged [IO_PAGE_FAULT device=02:00.0 domain=0x0000 address=0x000000007e2a80c0 flags=0x0050] 0000:02:00.0: eth2: Detected Hardware Unit Hang: ... The amd_iommu_destroy_domain() function calls do_detach() which doesn't reattach the pt domain to the device. Use __detach_device() instead.
