Subject: [PATCH v2 0/3] nfsd: fix v4.0 GSSAPI callback channel auth failures
Date: Sat, 21 Jun 2014 20:52:14 -0400

This is a respin of the kernel patchset that I sent back in early April
to fix the client's GSSAPI authentication in the v4.0 callback channel.
The userland piece of this has already been merged into nfs-utils.

The only real change here is to move the "stringification" of the
acceptor name out of the rpc_done callback and into the synchronous
caller. As Trond pointed out, we can't do that in rpciod callbacks as it
could recurse into writeback.

The callback now just takes a reference to the rpccred and stores a
pointer to it in the nfs4_setclientid struct. If that's non-NULL after
the call returns, we do the stringification there and then put the cred.

Jeff Layton (3):
  auth_gss: fetch the acceptor name out of the downcall
  sunrpc: add a new "stringify_acceptor" rpc_credop
  nfs4: copy acceptor name from context to nfs_client
