From d79f730bb8079948bb1c2d2e2b3205cba7152ca2 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Tue, 18 Jul 2023 08:38:37 -0400 Subject: [PATCH] nfsd: Remove incorrect check in nfsd4_validate_stateid commit f75546f58a70da5cfdcec5a45ffc377885ccbee8 upstream. If the client is calling TEST_STATEID, then it is because some event occurred that requires it to check all the stateids for validity and call FREE_STATEID on the ones that have been revoked. In this case, either the stateid exists in the list of stateids associated with that nfs4_client, in which case it should be tested, or it does not. There are no additional conditions to be considered. Reported-by: "Frank Ch. Eigler" Fixes: 7df302f75ee2 ("NFSD: TEST_STATEID should not return NFS4ERR_STALE_STATEID") Cc: stable@vger.kernel.org # v5.7+ Signed-off-by: Trond Myklebust Reviewed-by: Jeff Layton Signed-off-by: Chuck Lever Signed-off-by: Greg Kroah-Hartman --- fs/nfsd/nfs4state.c | 2 -- 1 file changed, 2 deletions(-) diff --git a/fs/nfsd/nfs4state.c b/fs/nfsd/nfs4state.c index 34561764e5c9..c5dc0cd6f703 100644 --- a/fs/nfsd/nfs4state.c +++ b/fs/nfsd/nfs4state.c @@ -6269,8 +6269,6 @@ static __be32 nfsd4_validate_stateid(struct nfs4_client *cl, stateid_t *stateid) if (ZERO_STATEID(stateid) || ONE_STATEID(stateid) || CLOSE_STATEID(stateid)) return status; - if (!same_clid(&stateid->si_opaque.so_clid, &cl->cl_clientid)) - return status; spin_lock(&cl->cl_lock); s = find_stateid_locked(cl, stateid); if (!s)
