[PATCH 0/1] xfs: fix log recovery buffer allocation for the

[Kevin Berry <kpberry@google.com>]

Hi folks, in order to fix CVE-2024-39472 in kernels 5.15, 6.1, and 6.6,
I have adapted the mainline patch 45cf976008dd (xfs: fix log recovery
buffer allocation for the legacy h_size fixup) to resolve conflicts
with those kernels. Specifically, the mainline patch uses kvfree, but
the amended patch uses kmem_free since kmem_free was used in xfs until
patch 49292576136f (xfs: convert kmem_free() for kvmalloc users to
kvfree()).

I tested the patch by applying it to the above kernels and recompiling
them. I also ran xfstests on the 6.6.43 kernel with the patch applied.
In my initial xfstests run, all xfs and generic tests passed except for
generic/082, generic/269, generic/627, and xfs/155, but those tests all
passed on a second run. I'm assuming those initial failures were
unrelated to this patch, unless someone more familiar with those tests
thinks otherwise.

I'd be more than happy to do any more verification or tests if they're
required. Thanks!
