From 34dc1ad752ad3f55b2a6e6cd8cfcf3504682fec7 Mon Sep 17 00:00:00 2001 From: Benny Halevy Date: Wed, 1 Apr 2009 09:22:52 -0400 Subject: nfs41: increment_{open,lock}_seqid Unlike minorversion0, in nfsv4.1 the open and lock seqids need not be incremented by the client and should always be set to zero. This is implemented using a new nfs_rpc_ops methods - increment_open_seqid and increment_lock_seqid Signed-off-by: Rahul Iyer Signed-off-by: Benny Halevy [nfs41: check for session not minorversion] Signed-off-by: Andy Adamson Signed-off-by: Benny Halevy Signed-off-by: Trond Myklebust --- fs/nfs/nfs4proc.c | 2 ++ fs/nfs/nfs4state.c | 12 +++++++----- 2 files changed, 9 insertions(+), 5 deletions(-) (limited to 'fs/nfs') diff --git a/fs/nfs/nfs4proc.c b/fs/nfs/nfs4proc.c index 31ce758d53d..f1f087b483c 100644 --- a/fs/nfs/nfs4proc.c +++ b/fs/nfs/nfs4proc.c @@ -1808,6 +1808,8 @@ int nfs4_do_close(struct path *path, struct nfs4_state *state, int wait) calldata->state = state; calldata->arg.fh = NFS_FH(state->inode); calldata->arg.stateid = &state->open_stateid; + if (nfs4_has_session(server->nfs_client)) + memset(calldata->arg.stateid->data, 0, 4); /* clear seqid */ /* Serialization for the sequence id */ calldata->arg.seqid = nfs_alloc_seqid(&state->owner->so_seqid); if (calldata->arg.seqid == NULL) diff --git a/fs/nfs/nfs4state.c b/fs/nfs/nfs4state.c index 2cc0aca96eb..2cfca9929c9 100644 --- a/fs/nfs/nfs4state.c +++ b/fs/nfs/nfs4state.c @@ -742,12 +742,14 @@ static void nfs_increment_seqid(int status, struct nfs_seqid *seqid) void nfs_increment_open_seqid(int status, struct nfs_seqid *seqid) { - if (status == -NFS4ERR_BAD_SEQID) { - struct nfs4_state_owner *sp = container_of(seqid->sequence, - struct nfs4_state_owner, so_seqid); + struct nfs4_state_owner *sp = container_of(seqid->sequence, + struct nfs4_state_owner, so_seqid); + struct nfs_server *server = sp->so_server; + + if (status == -NFS4ERR_BAD_SEQID) nfs4_drop_state_owner(sp); - } - nfs_increment_seqid(status, seqid); + if (!nfs4_has_session(server->nfs_client)) + nfs_increment_seqid(status, seqid); } /* -- cgit v1.2.3
