We want IPV6HEADER matching for the non-advanced default netfilter
configuration, since it's part of the standard netfilter setup of at
least some distributions (eg Fedora).
Otherwise NETFILTER_ADVANCED loses much of its point, since even
non-advanced users would have to enable all the advanced options just to
get a working IPv6 netfilter setup.

Clean up: have the set up routines explicitly pass the strings to be used
for the transport name and NETID. This removes a number of conditionals
and dependencies on rpc_xprt.prot, which is overloaded.
Tighten up type checking on the address_strings array while we're at it.

The gss_pipe_upcall() function expects the copy_to_user() function to
return a negative error value if the call fails, but copy_to_user()
returns an unsigned long number of bytes that couldn't be copied.
Can rpc_pipefs actually retry a partially completed upcall read? If
not, then gss_pipe_upcall() should punt any partial read, just like the
upcall logic in net/sunrpc/cache.c.

If the ULP doesn't pass a hostname string to rpc_create(), it manufactures
one based on the passed-in address. Be smart enough to handle an AF_INET6
address properly in this case.
Move the default servername logic before the xprt_create_transport() call
to simplify error handling in rpc_create().

The transport layer should do that itself whenever appropriate.
Note that the RDMA transport already assumes that it needs to call
xprt_disconnect in xprt_rdma_close().
For TCP sockets, we want to call xprt_disconnect() only after the
connection has been closed by both ends.

By using shutdown() rather than close() we allow the RPC client to wait
for the TCP close handshake to complete before we start trying to reconnect
using the same port.
We use shutdown(SHUT_WR) only instead of shutting down both directions,
however we wait until the server has closed the connection on its side.

Add an xprt->state bit to enable the TCP ->state_change() method to signal

Currently the TCP rebinding logic assumes that if we're not using a
reserved port, then we don't need to reconnect on the same port if a
disconnection event occurs. This breaks most RPC duplicate reply cache
implementations.
Also take into account the fact that xprt_min_resvport and
xprt_max_resvport may change while we're reconnecting, since the user may
change them at any time via the sysctls. Ensure that we check the port
boundaries every time we loop in xs_bind4/xs_bind6. Also ensure that if the
boundaries change, we only scan the ports a maximum of 2 times.

If an entry is being deleted because it has only one reference,
we immediately delete it and blindly register the rcu handler for it,
This results in oops by double freeing that object.
This patch fixes it by consolidating the code paths for the deletion;
let its rcu handler delete the object if it has no more reference.
