Subject: [PATCH v2 05/21] nfsd: check nfsd4_acl_to_attr() return value in nfsd4_create()
Date: Thu, 11 Jun 2026 16:00:48 -0400 [thread overview]
Message-ID: <20260611-nfsd-testing-v2-5-5b90e276f2d9@kernel.org> (raw)
In-Reply-To: <20260611-nfsd-testing-v2-0-5b90e276f2d9@kernel.org>
nfsd4_create() stores the return value of nfsd4_acl_to_attr() in
status, but the switch(create->cr_type) block unconditionally
overwrites it in every branch. ACL translation errors are silently
discarded, and the CREATE proceeds without the requested ACL.
Add an early exit check after nfsd4_acl_to_attr(), matching the
pattern already used in nfsd4_setattr().
Fixes: 4c10614c7b47 ("NFSD: move setting of ACLs into nfsd_setattr()")
