Merge tag 'xfs-5.7-merge-8' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux
Pull xfs updates from Darrick Wong:
"There's a lot going on this cycle with cleanups in the log code, the
btree code, and the xattr code.
We're tightening of metadata validation and online fsck checking, and
introducing a common btree rebuilding library so that we can refactor
xfs_repair and introduce online repair in a future cycle.
We also fixed a few visible bugs -- most notably there's one in
getdents that we introduced in 5.6; and a fix for hangs when disabling
quotas.
This series has been running fstests & other QA in the background for
over a week and looks good so far.
I anticipate sending a second pull request next week. That batch will
change how xfs interacts with memory reclaim; how the log batches and
throttles log items; how hard writes near ENOSPC will try to squeeze
more space out of the filesystem; and hopefully fix the last of the
umount hangs after a catastrophic failure. That should ease a lot of
problems when running at the limits, but for now I'm leaving that in
for-next for another week to make sure we got all the subtleties
right.
Summary:
- Fix a hard to trigger race between iclog error checking and log
shutdown.
- Strengthen the AGF verifier.
- Ratelimit some of the more spammy error messages.
- Remove the icdinode uid/gid members and just use the ones in the
vfs inode.
- Hold ILOCK across insert/collapse range.
- Clean up the extended attribute interfaces.
- Clean up the attr flags mess.
- Restore PF_MEMALLOC after exiting xfsaild thread to avoid
triggering warnings in the process accounting code.
- Remove the flexibly-sized array from struct xfs_agfl to eliminate
compiler warnings about unaligned pointers and packed structures.
- Various macro and typedef removals.
- Stale metadata buffers if we decide they're corrupt outside of a
verifier.
- Check directory data/block/free block owners.
- Fix a UAF when aborting inactivation of a corrupt xattr fork.
- Teach online scrub to report failed directory and attr name lookups
as a metadata corruption instead of a runtime error.
- Avoid potential buffer overflows in sysfs files by using scnprintf.
- Fix a regression in getdents lookups due to a mistake in pointer
arithmetic.
- Refactor btree cursor private data structures to use anonymous
unions.
- Cleanups in the log unmounting code.
- Fix a potential mishandling of ENOMEM errors on multi-block
directory buffer lookups.
- Fix an incorrect test in the block allocation code.
- Cleanups and name prefix shortening in the scrub code.
- Introduce btree bulk loading code for online repair and scrub.
- Fix a quotaoff log item leak (and hang) when the fs goes down
midway through a quotaoff operation.
- Remove di_version from the incore inode.
- Refactor some of the log shutdown checking code.
- Record the forcing of the log unmount records in the log force
counters.
- Fix a longstanding bug where quotacheck would purge the
administrator's default quota grace interval and warning limits.
- Reduce memory usage when scrubbing directory and xattr trees.
- Don't let fsfreeze race with GETFSMAP or online scrub.
- Handle bio_add_page failures more gracefully in xlog_write_iclog"
