* xfs: random buffer write failure errortagBrian Foster2020-05-071-0/+3

| | | | | | | | | | Add a xfs_failaddr_t parameter to this function so that callers can potentially pass in (and therefore report) the exact point in the code where we decided that a metadata buffer was corrupt. This enables us to wire it up to checking functions that have to run outside of verifiers. Signed-off-by: Darrick J. Wong <darrick.wong@oracle.com> Reviewed-by: Dave Chinner <dchinner@redhat.com>
* xfs: add a function to deal with corrupt buffers post-verifiersDarrick J. Wong2020-03-121-0/+2
| | | | | | | | | | | | Add a helper function to get rid of buffers that we have decided are corrupt after the verifiers have run. This function is intended to handle metadata checks that can't happen in the verifiers, such as inter-block relationship checking. Note that we now mark the buffer stale so that it will not end up on any LRU and will be purged on release. Signed-off-by: Darrick J.

Since these are on-disk contents (and not checks of internal state), we don't ever want to panic the kernel. This also amends the corruption report to recommend unmounting and running xfs_repair.

* xfs: cache unlinked pointers in an rhashtableDarrick J. Wong2019-02-111-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use a rhashtable to cache the unlinked list incore. This should speed up unlinked processing considerably when there are a lot of inodes on the unlinked list because iunlink_remove no longer has to traverse an entire bucket list to find which inode points to the one being removed. The incore list structure records "X.next_unlinked = Y" relations, with the rhashtable using Y to index the records. This makes finding the inode X that points to a inode Y very quick. If our cache fails to find anything we can always fall back on the old method. FWIW this drastically reduces the amount of time it takes to remove inodes from the unlinked list. I wrote a program to open a lot of O_TMPFILE files and then close them in the same order, which takes a very long time if we have to traverse the unlinked lists. With the ptach, I see: + /d/t/tmpfile/tmpfile Opened 193531 files in 6.33s.

* xfs: buffer lru reference count error injection tagBrian Foster2017-10-261-0/+3
| | | | | | | | | | | | | | | | | | | | | | | XFS uses a fixed reference count for certain types of buffers in the internal LRU cache. These reference counts dictate how aggressively certain buffers are reclaimed vs. others. While the reference counts implements priority across different buffer types, all buffers (other than uncached buffers) are typically cached for at least one reclaim cycle. We've had at least one bug recently that has been hidden by a released buffer sitting around in the LRU. Users hitting the problem were able to reproduce under enough memory pressure to cause aggressive reclaim in a particular window of time. To support future xfstests cases, add an error injection tag to hardcode the buffer reference count to zero. When enabled, this bypasses caching of associated buffers and facilitates test cases that depend on this behavior. Signed-off-by: Brian Foster <bfoster@redhat.com> Reviewed-by: Darrick J.

| | | | | | | | | | | | | | | | | | | Add an error injection tag to force log items in the AIL to the pinned state. This option can be used by test infrastructure to induce head behind tail conditions. Specifically, this is intended to be used by xfstests to reproduce log recovery problems after failed/corrupted log writes overwrite the last good tail LSN in the log. When enabled, AIL push attempts see log items in the AIL in the pinned state. This stalls metadata writeback and thus prevents the current tail of the log from moving forward. When disabled, subsequent AIL pushes observe the log items in their appropriate state and filesystem operation continues as normal.

* xfs: remove newlines from strings passed to __xfs_printkEric Sandeen2013-10-171-1/+1
| | | | | | | | | | | | | | | | | | | | __xfs_printk adds its own "\n". Having it in the original string leads to unintentional blank lines from these messages. Most format strings have no newline, but a few do, leading to i.e.: [ 7347.119911] XFS (sdb2): Access to block zero in inode 132 start_block: 0 start_off: 0 blkcnt: 0 extent-state: 0 lastx: 1a05 [ 7347.119911] [ 7347.119919] XFS (sdb2): Access to block zero in inode 132 start_block: 0 start_off: 0 blkcnt: 0 extent-state: 0 lastx: 1a05 [ 7347.119919] Fix them all.

* xfs: consolidate xfs_utils.cDave Chinner2013-08-121-1/+0
| | | | | | | | | | | There are a few small helper functions in xfs_util, all related to xfs_inode modifications. Move them all to xfs_inode.c so all xfs_inode operations are consiolidated in the one place.

* xfs: increase hexdump output in xfs_corruption_errorDave Chinner2013-04-211-1/+1
| | | | | | | | | | | | | Currently xfs_corruption_error() dumps the first 16 bytes of the buffer that is passed to it when a corruption occurs. This is not large enough to see the entire state of the header of the block that was determined to be corrupt. increase the output to 64 bytes to capture the majority of all headers in all types of metadata blocks.

* xfs: rename random32() to prandom_u32()Akinobu Mita2013-03-071-1/+1
| | | | | | | | | | | | | Use more preferable function name which implies using a pseudo-random number generator.
