      SUNRPC: Add a helper rpcauth_lookup_generic_cred() · 98a8e323
      Trond Myklebust 提交于
      The NFSv4 protocol allows clients to negotiate security protocols on the
      fly in the case where an administrator on the server changes the export
      settings and/or in the case where we may have a filesystem migration event.
      
      Instead of having the NFS client code cache credentials that are tied to a
      particular AUTH method it is therefore preferable to have a generic credential
      that can be converted into whatever AUTH is in use by the RPC client when
      the read/write/sillyrename/... is put on the wire.
      
      We do this by means of the new "generic" credential, which basically just
      caches the minimal information that is needed to look up an RPCSEC_GSS,
      AUTH_SYS, or AUTH_NULL credential.

      NFS: Add an nfsiod workqueue · 5746006f
      Trond Myklebust 提交于
      NFS post-rpciod cleanups often involve tasks that cannot be safely
      performed within the rpciod context (due to deadlock concerns). We
      therefore add a dedicated NFS workqueue that can perform tasks like
      cleaning up state after an interrupted NFSv4 open() call, or calling
      put_nfs_open_context() after an asynchronous read or write call.

      NFS: Fix a deadlock with lazy umount · 383ba719
      Trond Myklebust 提交于
      We can't allow rpc callback functions like task->tk_ops->rpc_call_prepare()
      and task->tk_ops->rpc_call_done() to call mntput() in any way, since
      that will cause a deadlock when the call to rpc_shutdown_client() attempts
      to wait on 'task' to complete.
      
      We can avoid the above deadlock by moving calls to mntput to
      task->tk_ops->rpc_release() callback, since at that time the task will be
      marked as completed, and so rpc_shutdown_client won't attempt to wait on
      it.
