Ensure that if an rpc_clnt owns more than one RPCSEC_GSS-based authentication mechanism, then those caches will share the same 'gssd' upcall pipe. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

The current system requires everyone to set up notifiers, manage directory locking, etc. What we really want to do is have the rpc_client create its directory, and then create all the entries. This patch will allow the RPCSEC_GSS and NFS code to register all the objects that they want to have appear in the directory, and then have the sunrpc code call them back to actually create/destroy their pipefs dentries when the rpc_client creates/destroys the parent.

If an error condition occurs on rpc_pipefs creation, or the user mounts rpc_pipefs and then unmounts it, then the dentries in struct gss_auth need to be reset to NULL so that a second call to gss_pipes_dentries_destroy doesn't try to free them again.

The clnt->cl_principal is being used exclusively to store the service target name for RPCSEC_GSS/krb5 callbacks. Replace it with something that is stored only in the RPCSEC_GSS-specific code. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

Optimise away gss_encode_msg: we don't need to look up the pipe version a second time. Save the gss target name in struct gss_auth. It is a property of the auth cache itself, and doesn't really belong in the rpc_client. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

After reclaiming state that was lost, the NFS client tries to reclaim any locks, and then checks that each one has NFS_LOCK_INITIALIZED set (which means that the server has confirmed the lock). However if the client holds a delegation, nfs_reclaim_locks() simply aborts (or more accurately it called nfs_lock_reclaim() and that returns without doing anything). This is because when a delegation is held, the server doesn't need to know about locks. So if a delegation is held, NFS_LOCK_INITIALIZED is not expected, and its absence is certainly not an error. So don't print the warnings if NFS_DELGATED_STATE is set. Signed-off-by: NeilBrown <neilb@suse.de> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
