SUNRPC: Use the already looked-up xprt in rpcb_getport_async()

2012-03-27T20:33:35+00:00

rbcb_getport_async() was looking up the rpc_xprt (reference++) and then
later looking it up again (reference++) to pass through the
rpcbind_args.  The xprt would only be dereferenced once, when we were
done with the rpcbind_args (reference--).  This leaves an extra
reference to the transport that would never go away.

SUNRPC: Move clnt->cl_server into struct rpc_xprt

2012-03-02T20:36:41+00:00

When the cl_xprt field is updated, the cl_server field will also have
to change.  Since the contents of cl_server follow the remote endpoint
of cl_xprt, just move that field to the rpc_xprt.

SUNRPC: Use RCU to dereference the rpc_clnt.cl_xprt field

2012-03-02T20:36:38+00:00

A migration event will replace the rpc_xprt used by an rpc_clnt.  To
ensure this can be done safely, all references to cl_xprt must now use
a form of rcu_dereference().

Special care is taken with rpc_peeraddr2str(), which returns a pointer
to memory whose lifetime is the same as the rpc_xprt.

SUNRPC: use proper network namespace in rpcbind RPCBPROC_GETADDR procedure

2012-02-01T00:28:13+00:00

Pass request socket network namespace to rpc_uaddr2sockaddr() instead of
hardcoded "init_net",  when decoding address in RPCBPROC_GETADDR procedure.
