afs: Fix infinite loop found by xfstest generic/676
In AFS, a directory is handled as a file that the client downloads and
parses locally for the purposes of performing lookup and getdents
operations. The in-kernel afs filesystem has a number of functions that
do this.
A directory file is arranged as a series of 2K blocks divided into
32-byte slots, where a directory entry occupies one or more slots, plus
each block starts with one or more metadata blocks.
When parsing a block, if the last slots are occupied by a dirent that
occupies more than a single slot and the file position points at a slot
that's not the initial one, the logic in afs_dir_iterate_block() that
skips over it won't advance the file pointer to the end of it. This
will cause an infinite loop in getdents() as it will keep retrying that
block and failing to advance beyond the final entry.
Fix this by advancing the file pointer if the next entry will be beyond
it when we skip a block.
This was found by the generic/676 xfstest but can also be triggered with
something like:
~/xfstests-dev/src/t_readdir_3 /xfstest.test/z 4000 1

f2fs-for-5.19
In this round, we've refactored the existing atomic write support implemented
by in-memory operations to have storing data in disk temporarily, which can give
us a benefit to accept more atomic writes. At the same time, we removed the
existing volatile write support. We've also revisited the file pinning and GC
flows and found some corner cases which contributeed abnormal system behaviours.
As usual, there're several minor code refactoring for readability, sanity check,
and clean ups.
Enhancement
- allow compression for mmap files in compress_mode=user
- kill volatile write support
- change the current atomic write way
- give priority to select unpinned section for foreground GC
- introduce data read/write showing path info
- remove unnecessary f2fs_lock_op in f2fs_new_inode
Bug fix
- fix the file pinning flow during checkpoint=disable and GCs
- fix foreground and background GCs to select the right victims and get free
sections on time
- fix GC flags on defragmenting pages
- avoid an infinite loop to flush node pages
- fix fallocate to use file_modified to update permissions consistently

Merge branch 'guilt/xfs-5.19-larp-cleanups' into xfs-5.19-for-next
This series contains a two key cleanups for the new LARP code. Most of it is refactoring and tweaking the code that creates kernel log messages about enabling and disabling features -- we should be warning about LARP being turned on once per mount, instead of once per insmod cycle; we shouldn't be spamming the logs so aggressively about turning *off* log incompat features. The second part of the series refactors the LARP code responsible for getting (and releasing) permission to use xattr log items. The implementation code doesn't belong in xfs_log.c, and calls to logging functions don't belong in libxfs -- they really should be done by the VFS implementation functions before they start calling into libraries.

erofs: leave compressed inodes unsupported in fscache mode for now
erofs over fscache doesn't support the compressed layout yet. It will
cause NULL crash if there are compressed inodes contained when working
in fscache mode.
So far in the erofs based container image distribution scenarios
(RAFS v6), the compressed RAFS v6 images are downloaded and then
decompressed on demand as an uncompressed erofs image. Then the erofs
image is mounted in fscache mode for containers to use. IOWs, currently
compressed data is decompressed on the userspace side instead and
uncompressed erofs images will be finally cached.
The fscache support for the compressed layout is still under
development and it will be used for runtime decompression feature.
Anyway, to avoid the potential crash, let's leave the compressed inodes
unsupported in fscache mode until we support it later.

"New support for clearing memory errors when a file is in DAX mode,
alongside with some other fixes and cleanups.
Previously it was only possible to clear these errors using a truncate
or hole-punch operation to trigger the filesystem to reallocate the
block, now, any page aligned write can opportunistically clear errors
as well.
This change spans x86/mm, nvdimm, and fs/dax, and has received the
appropriate sign-offs. Thanks to Jane for her work on this.

pipe: Fix missing lock in pipe_resize_ring()
pipe_resize_ring() needs to take the pipe->rd_wait.lock spinlock to
prevent post_one_notification() from trying to insert into the ring
whilst the ring is being replaced.
The occupancy check must be done after the lock is taken, and the lock
must be taken after the new ring is allocated.
The bug can lead to an oops looking something like:

NFSD 5.19 Release Notes
We introduce "courteous server" in this release. Previously NFSD would purge open and lock state for an unresponsive client after one lease period (typically 90 seconds). Now, after one lease period, another client can open and lock those files and the unresponsive client's lease is purged; otherwise if the unrespon- sive client's open and lock state is uncontended, the server retains that open and lock state for up to 24 hours, allowing the client's workload to resume after a lengthy network partition. A longstanding issue with NFSv4 file creation is also addressed. Previously a file creation can fail internally, returning an error to the client, but leave the newly created file in place as an artifact. The file creation code path has been reorganized so that internal failures and race conditions are less likely to result in an unwanted file creation. A fault injector has been added to help exercise paths that are run during kernel metadata cache invalidation. These caches contain information maintained by user space about exported filesystems. Many of our test workloads do not trigger cache invalidation. There is one patch that is needed to support PREEMPT_RT and a fix for an ancient "sleep while spin-locked" splat that seems to have become easier to hit since v5.18-rc3. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEKLLlsBKG3yQ88j7+M2qzM29mf5cFAmKPliAACgkQM2qzM29m f5dB3BAAorPa2L8xu5P1Ge1oTNogNSOVRkLPDzEkfEwK07ZM2qvz78eMZGkMziJ/ strorvBWl3SWBlVtTePgNpJUjgYQ75MRRwaX7Qh2WuHeRKm1JlZm0/NId3+zKgbh N40QI20jdswWcNDuhidxVFFWurd09GlcM4z1cu8gZLbfthkiUOjZoPiLkXeNcvhk 7wC9GiueWxHefYQQDAKh1nQS/L0GG1EkzJdJo7WUVAldZ9qVY9LpmJVMRqrBBbta XrFYfpeY1zFFDY4Qolyz5PUJSeQuDj9PctlhoZ6B1hp56PD/6yaqVhYXiPxtlALj tITtktfiekULZkgfvfvyzssCv+wkbYiaEBZcSSCauR7dkGOmBmajO+cf7vpsERgE fbCU8DWGk78SMeehdCrO+26cV37VP+8c2t2Txq/rG5Eq4ZoCi++Hj5poRboFLqb+ oom+0Ee0LfcAKXkxH5gWTPTblHo49GzGitPZtRzTgZ9uFnVwvEaJ4+t0ij0J8JpL HuVtWrg5/REhqpEvOSwF0sRmkYWLTu7KdueGn/iZ8xUi7GHEue01NsVkClohKJcR WOjWrbNCNF/LJaG88MX0z5u7IO7s9bOHphd7PJ92vR+4YsehW3uRhk+rNi2ZBqQz hzULfu8BiaicV9fdB/hDcMmKQD6U6due2AVVPtxTf5XY+CHQNRY= =phE1 -----END PGP SIGNATURE----- Merge tag 'nfsd-5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/cel/linux Pull nfsd updates from Chuck Lever: "We introduce 'courteous server' in this release.

xfs: implement per-mount warnings for scrub and shrink usage
Currently, we don't have a consistent story around logging when an EXPERIMENTAL feature gets turned on at runtime -- online fsck and shrink log a message once per day across all mounts, and the recently merged LARP mode only ever does it once per insmod cycle or reboot. Because EXPERIMENTAL tags are supposed to go away eventually, convert the existing daily warnings into state flags that travel with the mount, and warn once per mount. Making this an opstate flag means that we'll be able to capture the experimental usage in the ftrace output too. Signed-off-by: Darrick J.

xfs: don't leak btree cursor when insrec fails after a split
The recent patch to improve btree cycle checking caused a regression
when I rebased the in-memory btree branch atop the 5.19 for-next branch,
because in-memory short-pointer btrees do not have AG numbers. This
produced the following complaint from kmemleak:

xfs: purge dquots after inode walk fails during quotacheck
xfs/434 and xfs/436 have been reporting occasional memory leaks of
xfs_dquot objects. These tests themselves were the messenger, not the
culprit, since they unload the xfs module, which trips the slub
debugging code while tearing down all the xfs slab caches:

Since we don't generally rmmod the xfs module between fstests, this
means that xfs/434 is really just the canary in the coal mine --
something leaked a dquot, but we don't know who. After days of pounding
on fstests with kmemleak enabled, I finally got it to spit this out:

Now we know that quotacheck is at fault, but even this report was
canaryish -- it was triggered by xfs/494, which doesn't actually mount
any filesystems. (kmemleak can be a little slow to notice leaks, even
with fstests repeatedly whacking it to look for them.) Looking at the
*previous* fstest, however, showed that the test run before xfs/494 was
xfs/117. The tipoff to the problem is in this excerpt from dmesg:

XFS (sda4): Quotacheck: Unsuccessful (Error -117): Disabling quotas.
The dinode verifier decided that the inode was corrupt, which causes
iget to return with EFSCORRUPTED. Since this happened during
quotacheck, it is obvious that the kernel aborted the inode walk on
account of the corruption error and disabled quotas. Unfortunately, we
neglect to purge the dquot cache before doing that, which is how the
dquots leaked.
The problems started 10 years ago in commit b84a3a, when the dquot lists
were converted to a radix tree, but the error handling behavior was not
correctly preserved -- in that commit, if the bulkstat failed and
usrquota was enabled, the bulkstat failure code would be overwritten by
the result of flushing all the dquots to disk. As long as that
succeeds, we'd continue the quota mount as if everything were ok, but
instead we're now operating with a corrupt inode and incorrect quota
usage counts. I didn't notice this bug in 2019 when I wrote commit

xfs: assert in xfs_btree_del_cursor should take into account error
xfs/538 on a 1kB block filesystem failed with this assert: XFS: Assertion failed: cur->bc_btnum != XFS_BTNUM_BMAP || cur->bc_ino.allocated == 0 || xfs_is_shutdown(cur->bc_mp), file: fs/xfs/libxfs/xfs_btree.c, line: 448 The problem was that an allocation failed unexpectedly in xfs_bmbt_alloc_block() after roughly 150,000 minlen allocation error injections, resulting in an EFSCORRUPTED error being returned to xfs_bmapi_write(). The error occurred on extent-to-btree format conversion allocating the new root block: RIP: 0010:xfs_bmbt_alloc_block+0x177/0x210 Call Trace: <TASK> xfs_btree_new_iroot+0xdf/0x520 xfs_btree_make_block_unfull+0x10d/0x1c0 xfs_btree_insrec+0x364/0x790 xfs_btree_insert+0xaa/0x210 xfs_bmap_add_extent_hole_real+0x1fe/0x9a0 xfs_bmapi_allocate+0x34c/0x420 xfs_bmapi_write+0x53c/0x9c0 xfs_alloc_file_space+0xee/0x320 xfs_file_fallocate+0x36b/0x450 vfs_fallocate+0x148/0x340 __x64_sys_fallocate+0x3c/0x70 do_syscall_64+0x35/0x80 entry_SYSCALL_64_after_hwframe+0x44/0xa Why the allocation failed at this point is unknown, but is likely that we ran the transaction out of reserved space and filesystem out of space with bmbt blocks because of all the minlen allocations being done causing worst case fragmentation of a large allocation. Regardless of the cause, we've then called xfs_bmapi_finish() which calls xfs_btree_del_cursor(cur, error) to tear down the cursor. So we have a failed operation, error != 0, cur->bc_ino.allocated > 0 and the filesystem is still up. The assert fails to take into account that allocation can fail with an error and the transaction teardown will shut the filesystem down if necessary. i.e. the assert needs to check "|| error != 0" as well, because at this point shutdown is pending because the current transaction is dirty....

xfs: don't assert fail on perag references on teardown
Not fatal, the assert is there to catch developer attention. I'm seeing this occasionally during recoveryloop testing after a shutdown, and I don't want this to stop an overnight recoveryloop run as it is currently doing. Convert the ASSERT to a XFS_IS_CORRUPT() check so it will dump a corruption report into the log and cause a test failure that way, but it won't stop the machine dead.

sysctl changes for v5.19-rc1
For two kernel releases now kernel/sysctl.c has been being cleaned up slowly, since the tables were grossly long, sprinkled with tons of #ifdefs and all this caused merge conflicts with one susbystem or another. This tree was put together to help try to avoid conflicts with these cleanups going on different trees at time. So nothing exciting on this pull request, just cleanups. I actually had this sysctl-next tree up since v5.18 but I missed sending a pull request for it on time during the last merge window. And so these changes have been being soaking up on sysctl-next and so linux-next for a while. The last change was merged May 4th. Most of the compile issues were reported by 0day and fixed. To help avoid a conflict with bpf folks at Daniel Borkmann's request I merged bpf-next/pr/bpf-sysctl into sysctl-next to get the effor which moves the BPF sysctls from kernel/sysctl.c to BPF core.
