Subject: [PATCH AUTOSEL 6.5 22/52] nfs42: client needs to strip file mode's suid/sgid bit after ALLOCATE op
Date: Sun, 29 Oct 2023 18:53:09 -0400 [thread overview]
Message-ID: <20231029225441.789781-22-sashal@kernel.org> (raw)
In-Reply-To: <20231029225441.789781-1-sashal@kernel.org>
From: Dai Ngo <dai.ngo@oracle.com>
[ Upstream commit f588d72bd95f748849685412b1f0c7959ca228cf ]
The Linux NFS server strips the SUID and SGID from the file mode
on ALLOCATE op.
Modify _nfs42_proc_fallocate to add NFS_INO_REVAL_FORCED to
nfs_set_cache_invalid's argument to force update of the file
mode suid/sgid bit.
