From: Trond Myklebust Date: Fri, 17 Oct 2014 12:15:13 +0000 (+0300) Subject: NFSv4: Ensure that we call FREE_STATEID when NFSv4.x stateids are revoked X-Git-Tag: v3.17.4~37 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=bc8ef9cbba9cb9d78bd20d801a3fe1a348453b81;p=thirdparty%2Fkernel%2Fstable.git NFSv4: Ensure that we call FREE_STATEID when NFSv4.x stateids are revoked commit c606bb8857921d3ecf4d353942d6cc7e116cc75a upstream. NFSv4.x (x>0) requires us to call TEST_STATEID+FREE_STATEID if a stateid is revoked. We will currently fail to do this if the stateid is a delegation. http://lkml.kernel.org/r/CAN-5tyHwG=Cn2Q9KsHWadewjpTTy_K26ee+UnSvHvG4192p-Xw@mail.gmail.com Signed-off-by: Trond Myklebust Signed-off-by: Greg Kroah-Hartman --- diff --git a/fs/nfs/filelayout/filelayout.c b/fs/nfs/filelayout/filelayout.c index f59713e091a82..eb777ed345680 100644 --- a/fs/nfs/filelayout/filelayout.c +++ b/fs/nfs/filelayout/filelayout.c @@ -145,9 +145,6 @@ static int filelayout_async_handle_error(struct rpc_task *task, case -NFS4ERR_DELEG_REVOKED: case -NFS4ERR_ADMIN_REVOKED: case -NFS4ERR_BAD_STATEID: - if (state == NULL) - break; - nfs_remove_bad_delegation(state->inode); case -NFS4ERR_OPENMODE: if (state == NULL) break; diff --git a/fs/nfs/nfs4proc.c b/fs/nfs/nfs4proc.c index 3a251359285af..877d022497cc2 100644 --- a/fs/nfs/nfs4proc.c +++ b/fs/nfs/nfs4proc.c @@ -360,11 +360,6 @@ static int nfs4_handle_exception(struct nfs_server *server, int errorcode, struc case -NFS4ERR_DELEG_REVOKED: case -NFS4ERR_ADMIN_REVOKED: case -NFS4ERR_BAD_STATEID: - if (inode != NULL && nfs4_have_delegation(inode, FMODE_READ)) { - nfs_remove_bad_delegation(inode); - exception->retry = 1; - break; - } if (state == NULL) break; ret = nfs4_schedule_stateid_recovery(server, state); @@ -4849,9 +4844,6 @@ nfs4_async_handle_error(struct rpc_task *task, const struct nfs_server *server, case -NFS4ERR_DELEG_REVOKED: case -NFS4ERR_ADMIN_REVOKED: case -NFS4ERR_BAD_STATEID: - if (state == NULL) - break; - nfs_remove_bad_delegation(state->inode); case -NFS4ERR_OPENMODE: if (state == NULL) break;
