btrfs: move extent locking outside of btrfs_truncate_inode_items
Currently we are locking the extent and dropping the extent cache for any inodes we truncate, unless they're in the tree log. We call this helper from:
- truncate - evict - tree log - free space cache truncation
For evict we've already dropped all of the extent cache for this inode once we've gotten here, and we're the only one accessing this inode, so this step is unnecessary.
For the tree log code we already skip this part.
Pull this work into the truncate path and the free space cache truncation path.

This is an inode item related manipulation with a few vfs related adjustments. I'm going to remove the vfs related code from this helper and simplify it a lot, but I want those changes to be easily seen via git blame, so move this function now and then the simplification work can be done.

btrfs: Remove custom crc32c init code
The custom crc32 init code was introduced in 14a958e678cd ("Btrfs: fix btrfs boot when compiled as built-in") to enable using btrfs as a built-in. However, later as pointed out by 60efa5eb2e88 ("Btrfs: use late_initcall instead of module_init") this wasn't enough and finally btrfs was switched to late_initcall which comes after the generic crc32c implementation is initiliased. The latter commit superseeded the former. Now that we don't have to maintain our own code let's just remove it and switch to using the generic implementation.
Despite touching a lot of files the patch is really simple. Here is the gist of the changes:
1. Select LIBCRC32C rather than the low-level modules. 2. s/btrfs_crc32c/crc32c/g 3. replace hash.h with linux/crc32c.h 4. Move the btrfs namehash funcs to ctree.h and change the tree accordingly.
I've tested this with btrfs being both a module and a built-in and xfstest doesn't complain.
Does seem to fix the longstanding problem of not automatically selectiong the crc32c module when btrfs is used. Possibly there is a workaround in dracut.
The modinfo confirms that now all the module dependencies are there:
before: depends: zstd_compress,zstd_decompress,raid6_pq,xor,zlib_deflate
after: depends: libcrc32c,zstd_compress,zstd_decompress,raid6_pq,xor,zlib_deflate

Btrfs: fix log replay failure after unlink and link combination
If we have a file with 2 (or more) hard links in the same directory, remove one of the hard links, create a new file (or link an existing file) in the same directory with the name of the removed hard link, and then finally fsync the new file, we end up with a log that fails to replay, causing a mount failure.
Example:
$ mkfs.btrfs -f /dev/sdb $ mount /dev/sdb /mnt
$ mkdir /mnt/testdir $ touch /mnt/testdir/foo $ ln /mnt/testdir/foo /mnt/testdir/bar
$ sync
$ unlink /mnt/testdir/bar $ touch /mnt/testdir/bar $ xfs_io -c "fsync" /mnt/testdir/bar
<power failure>
$ mount /dev/sdb /mnt mount: mount(2) failed: /mnt: No such file or directory
When replaying the log, for that example, we also see the following in dmesg/syslog:

This happens because the log has inode reference items for both inode 258 (the first file we created) and inode 259 (the second file created), and when processing the reference item for inode 258, we replace the corresponding item in the subvolume tree (which has two names, "foo" and "bar") witht he one in the log (which only has one name, "foo") without removing the corresponding dir index keys from the parent directory. Later, when processing the inode reference item for inode 259, which has a name of "bar" associated to it, we notice that dir index entries exist for that name and for a different inode, so we attempt to unlink that name, which fails because the inode reference item for inode 258 no longer has the name "bar" associated to it, making a call to btrfs_unlink_inode() fail with a -ENOENT error.
Fix this by unlinking all the names in an inode reference item from a subvolume tree that are not present in the inode reference item found in the log tree, before overwriting it with the item from the log tree.

Btrfs: fix fsync log replay for inodes with a mix of regular refs and extrefs
If we have an inode with a large number of hard links, some of which may be extrefs, turn a regular ref into an extref, fsync the inode and then replay the fsync log (after a crash/reboot), we can endup with an fsync log that makes the replay code always fail with -EOVERFLOW when processing the inode's references.
This is easy to reproduce with the test case I made for xfstests. Its steps are the following:
_scratch_mkfs "-O extref" >> $seqres.full 2>&1 _init_flakey _mount_flakey
# Create a test file with 3001 hard links. This number is large enough to # make btrfs start using extrefs at some point even if the fs has the maximum # possible leaf/node size (64Kb). echo "hello world" > $SCRATCH_MNT/foo for i in `seq 1 3000`; do ln $SCRATCH_MNT/foo $SCRATCH_MNT/foo_link_`printf "%04d" $i` done
# Make sure all metadata and data are durably persisted. sync
# Now remove one link, add a new one with a new name, add another new one with # the same name as the one we just removed and fsync the inode. rm -f $SCRATCH_MNT/foo_link_0001 ln $SCRATCH_MNT/foo $SCRATCH_MNT/foo_link_3001 ln $SCRATCH_MNT/foo $SCRATCH_MNT/foo_link_0001 rm -f $SCRATCH_MNT/foo_link_0002 ln $SCRATCH_MNT/foo $SCRATCH_MNT/foo_link_3002 ln $SCRATCH_MNT/foo $SCRATCH_MNT/foo_link_3003 $XFS_IO_PROG -c "fsync" $SCRATCH_MNT/foo
# Simulate a crash/power loss. This makes sure the next mount # will see an fsync log and will replay that log.
_load_flakey_table $FLAKEY_DROP_WRITES _unmount_flakey
_load_flakey_table $FLAKEY_ALLOW_WRITES _mount_flakey
# Check that the number of hard links is correct, we are able to remove all # the hard links and read the file's data. This is just to verify we don't # get stale file handle errors (due to dangling directory index entries that # point to inodes that no longer exist). echo "Link count: $(stat --format=%h $SCRATCH_MNT/foo)" [ -f $SCRATCH_MNT/foo ] || echo "Link foo is missing" for ((i = 1; i <= 3003; i++)); do name=foo_link_`printf "%04d" $i` if [ $i -eq 2 ]; then [ -f $SCRATCH_MNT/$name ] && echo "Link $name found" else [ -f $SCRATCH_MNT/$name ] || echo "Link $name is missing" fi done rm -f $SCRATCH_MNT/foo_link_* cat $SCRATCH_MNT/foo rm -f $SCRATCH_MNT/foo
status=0 exit
The fix is simply to correct the overflow condition when overwriting a reference item because it was wrong, trying to increase the item in the fs/subvol tree by an impossible amount. Also ensure that we don't insert one normal ref and one ext ref for the same dentry - this happened because processing a dir index entry from the parent in the log happened when the normal ref item was full, which made the logic insert an extref and later when the normal ref had enough room, it would be inserted again when processing the ref item from the child inode in the log.
This issue has been present since the introduction of the extrefs feature (2012).
A test case for xfstests follows soon. This test only passes if the previous patch titled "Btrfs: fix fsync when extend references are added to an inode" is applied too.
