Subject: [PATCH AUTOSEL 4.9 09/16] NFS: Correct size calculation for create reply length
Date: Tue, 16 Mar 2021 20:59:40 -0400 [thread overview]
Message-ID: <20210317005948.727250-9-sashal@kernel.org> (raw)
In-Reply-To: <20210317005948.727250-1-sashal@kernel.org>
From: Frank Sorenson <sorenson@redhat.com>
[ Upstream commit ad3dbe35c833c2d4d0bbf3f04c785d32f931e7c9 ]
CREATE requests return a post_op_fh3, rather than nfs_fh3. The
post_op_fh3 includes an extra word to indicate 'handle_follows'.
Without that additional word, create fails when full 64-byte
filehandles are in use.
Add NFS3_post_op_fh_sz, and correct the size calculation for
NFS3_createres_sz.
