Subject: [PATCH v2 0/9] nfsd: fixes for locally-triggerable bugs
Date: Tue, 02 Jun 2026 12:23:12 -0400 [thread overview]
Message-ID: <20260602-nfsd-testing-v2-0-e4ea62e3cd5c@kernel.org> (raw)
Just some minor changes in this version, plus a cleanup patch from Al.
These are bugs that Claude classified as locally-triggerable. A couple
can be triggered by an unprivileged user, but the rest require admin
access.
The last 3 patches fix one bug. I originally had a more targeted fix
that kres generated, but I think it's better to simplify the filecache
disposal mechanism to get rid of the bug rather than add more
complexity.
Signed-off-by: Jeff Layton <jlayton@kernel.org>

Changes in v2:
- rework filecache patch to only take net ref at disposal time
- fix ordering of operations in nfsd4_release_compoundargs()
- add Al's patch to simplify nfsd_cross_mnt() cleanup
- Link to v1: https://lore.kernel.org/r/20260601-nfsd-testing-v1-0-d0f61e536df8@kernel.org
