Merge tag 'scrub-fix-xattr-memory-mgmt-6.4_2023-04-11' of git://git.kernel.org/pub/scm/linux/kernel/git/djwong/xfs-linux into guilt/xfs-for-next
xfs: clean up memory management in xattr scrub [v24.5]
Currently, the extended attribute scrubber uses a single VLA to store
all the context information needed in various parts of the scrubber
code. This includes xattr leaf block space usage bitmaps, and the value
buffer used to check the correctness of remote xattr value block
headers. We try to minimize the insanity through the use of helper
functions, but this is a memory management nightmare. Clean this up by
making the bitmap and value pointers explicit members of struct
xchk_xattr_buf.
Second, strengthen the xattr checking by teaching it to look for overlapping
data structures in the shortform attr data.
