9392557 Akinobu Mita 15 November 2011, 22:56:34 UTC ocfs2: avoid unaligned access to dqc_bitmap The dqc_bitmap field of struct ocfs2_local_disk_chunk is 32-bit aligned, but not 64-bit aligned. The dqc_bitmap is accessed by ocfs2_set_bit(), ocfs2_clear_bit(), ocfs2_test_bit(), or ocfs2_find_next_zero_bit(). These are wrapper macros for ext2_*_bit() which need to take an unsigned long aligned address (though some architectures are able to handle unaligned address correctly) So some 64bit architectures may not be able to access the dqc_bitmap correctly. This avoids such unaligned access by using another wrapper functions for ext2_*_bit(). The code is taken from fs/ext4/mballoc.c which also need to handle unaligned bitmap access.

f4a8e65 Jan Schmidt 01 December 2011, 14:30:36 UTC Btrfs: fix meta data raid-repair merge problem Commit 4a54c8c16 introduced raid-repair, killing the individual readpage_io_failed_hook entries from inode.c and disk-io.c. Commit 4bb31e92 introduced new readahead code, adding a readpage_io_failed_hook to disk-io.c. The raid-repair commit had logic to disable raid-repair, if readpage_io_failed_hook is set. Thus, the readahead commit effectively disabled raid-repair for meta data. This commit changes the logic to always attempt raid-repair when needed and call the readpage_io_failed_hook in case raid-repair fails. This is much more straight forward and should have been like that from the beginning.

b5bed7f Jon Medhurst (Tixy) 29 November 2011, 07:16:02 UTC ARM: 7181/1: Restrict kprobes probing SWP instructions to ARMv5 and below The SWP instruction is deprecated on ARMv6 and with ARMv7 it will be UNDEFINED when CONFIG_SWP_EMULATE is selected. In this case, probing a SWP instruction will cause an oops when the kprobes emulation code executes an undefined instruction. As the SWP instruction should be rare or non-existent in kernels for ARMv6 and later, we can simply avoid these problems by not allowing probing of these.

14383c2 Jon Medhurst (Tixy) 29 November 2011, 07:14:35 UTC ARM: 7180/1: Change kprobes testcase with unpredictable STRD instruction There is a kprobes testcase for the instruction "strd r2, [r3], r4". This has unpredictable behaviour as it uses r3 for register writeback addressing and also stores it to memory. On a cortex A9, this testcase would fail because the instruction writes the updated value of r3 to memory, whereas the kprobes emulation code writes the original value. Fix this by changing testcase to used r5 instead of r3.

425d831 Alexandre Oliva 30 November 2011, 18:43:00 UTC Btrfs: skip block groups without enough space for a cluster We test whether a block group has enough free space to hold the requested block, but when we're doing clustered allocation, we can save some cycles by testing whether it has enough room for the cluster upfront, otherwise we end up attempting to set up a cluster and failing. Only in the NO_EMPTY_SIZE loop do we attempt an unclustered allocation, and by then we'll have zeroed the cluster size, so this patch won't stop us from using the block group as a last resort.

b78d09b Alexandre Oliva 30 November 2011, 18:43:00 UTC Btrfs: reset cluster's max_size when creating bitmap The field that indicates the size of the largest contiguous chunk of free space in the cluster is not initialized when setting up bitmaps, it's only increased when we find a larger contiguous chunk. We end up retaining a larger value than appropriate for highly-fragmented clusters, which may cause pointless searches for large contiguous groups, and even cause clusters that do not meet the density requirements to be set up.

f2d0f67 Alexandre Oliva 28 November 2011, 14:04:43 UTC Btrfs: initialize new bitmaps' list We're failing to create clusters with bitmaps because setup_cluster_no_bitmap checks that the list is empty before inserting the bitmap entry in the list for setup_cluster_bitmap, but the list field is only initialized when it is restored from the on-disk free space cache, or when it is written out to disk. Besides a potential race condition due to the multiple use of the list field, filesystem performance severely degrades over time: as we use up all non-bitmap free extents, the try-to-set-up-cluster dance is done at every metadata block allocation. For every block group, we fail to set up a cluster, and after failing on them all up to twice, we fall back to the much slower unclustered allocation. To make matters worse, before the unclustered allocation, we try to create new block groups until we reach the 1% threshold, which introduces additional bitmaps and thus block groups that we'll iterate over at each metadata block request. 30 November 2011, 17:46:06 UTC

aa38a71 Miao Xie 18 November 2011, 09:43:00 UTC Btrfs: fix deadlock on metadata reservation when evicting a inode When I ran the xfstests, I found the test tasks was blocked on meta-data reservation. By debugging, I found the reason of this bug: start transaction | v reserve meta-data space | v flush delay allocation -> iput inode -> evict inode ^ | | v wait for delay allocation flush <- reserve meta-data space And besides that, the flush on evicting inode will block the thread, which is reclaiming the memory, and make oom happen easily.

There are GFP_ATOMIC allocates in the provider routines, so this is possible and should be dealt with. The test that induced the failure is associated with a host SM on the same server during a shutdown. This patch causes ipoib_mcast_join_finish() to exit with an error which will flush the queued mcast packets. Nothing is done to unwind the QP attached state so that subsequent sends from above will retry the join.

Amidst reorganizing 'try_one_irq', that patch removed a test that checked for 'action->handler' returning IRQ_HANDLED, before acting on the interrupt. Restoring this test back returns the functionality lost since 2.6.39. In the current set of tests, after 'action' is set, it must precede '!action->next' to take effect. With this and my previous patch to irq/spurious.c, c75d720fca8a, all IRQ regressions that I have encountered are fixed.

884a45d Michal Hocko 22 November 2011, 15:44:47 UTC cgroup_freezer: fix freezing groups with stopped tasks 2d3cbf8b (cgroup_freezer: update_freezer_state() does incorrect state transitions) removed is_task_frozen_enough and replaced it with a simple frozen call. This, however, breaks freezing for a group with stopped tasks because those cannot be frozen and so the group remains in CGROUP_FREEZING state (update_if_frozen doesn't count stopped tasks) and never reaches CGROUP_FROZEN. Let's add is_task_frozen_enough back and use it at the original locations (update_if_frozen and try_to_freeze_cgroup). Semantically we consider stopped tasks as frozen enough so we should consider both cases when testing frozen tasks. Testcase: mkdir /dev/freezer mount -t cgroup -o freezer none /dev/freezer mkdir /dev/freezer/foo sleep 1h & pid=$! kill -STOP $pid echo $pid > /dev/freezer/foo/tasks echo FROZEN > /dev/freezer/foo/freezer.state while true do cat /dev/freezer/foo/freezer.state [ "`cat /dev/freezer/foo/freezer.state`" = "FROZEN" ] && break sleep 1 done echo OK Signed-off-by: Michal Hocko <mhocko@suse.cz> Acked-by: Li Zefan <lizf@cn.fujitsu.com> Cc: Tomasz Buchert <tomasz.buchert@inria.fr> Cc: Paul Menage <paul@paulmenage.org> Cc: Andrew Morton <akpm@linux-foundation.org> Cc: stable@kernel.org Signed-off-by: Tejun Heo <htejun@gmail.com> 24 November 2011, 19:58:22 UTC

e6af578 Michael S. Tsirkin 17 November 2011, 15:41:15 UTC virtio-pci: make reset operation safer virtio pci device reset actually just does an I/O write, which in PCI is really posted, that is it can complete on CPU before the device has received it. Further, interrupts might have been pending on another CPU, so device callback might get invoked after reset. This conflicts with how drivers use reset, which is typically: reset unregister a callback running after reset completed can race with unregister, potentially leading to use after free bugs. Fix by flushing out the write, and flushing pending interrupts. This assumes that device is never reset from its vq/config callbacks, or in parallel with being added/removed, document this assumption. Signed-off-by: Michael S.
