Merge tag 'nfs-for-3.14-4' of git://git.linux-nfs.org/projects/trondmy/linux-nfs

Pull NFS client bugfixes from Trond Myklebust:
 "Highlights include stable fixes for the following bugs:

   - General performance regression due to NFS_INO_INVALID_LABEL being
     set when the server doesn't support labeled NFS
   - Hang in the RPC code due to a socket out-of-buffer race
   - Infinite loop when trying to establish the NFSv4 lease
   - Use-after-free bug in the RPCSEC gss code.
   - nfs4_select_rw_stateid is returning with a non-zero error value on
     success

  Other bug fixes:

  - Potential memory scribble in the RPC bi-directional RPC code
  - Pipe version reference leak
  - Use the correct net namespace in the new NFSv4 migration code"

* tag 'nfs-for-3.14-4' of git://git.linux-nfs.org/projects/trondmy/linux-nfs:
  NFS fix error return in nfs4_select_rw_stateid
  NFSv4: Use the correct net namespace in nfs4_update_server
  SUNRPC: Fix a pipe_version reference leak
  SUNRPC: Ensure that gss_auth isn't freed before its upcall messages
  SUNRPC: Fix potential memory scribble in xprt_free_bc_request()
  SUNRPC: Fix races in xs_nospace()
  SUNRPC: Don't create a gss auth cache unless rpc.gssd is running
  NFS: Do not set NFS_INO_INVALID_LABEL unless server supports labeled NFS
