Subject: [PATCH net 0/2] l2tp: socket lookup fixes for l2tp_ip and l2tp_ip6

There are still some cases that aren't correctly handled in the socket
lookup functions of l2tp_ip and l2tp_ip6. This series fixes lookups for
connected sockets and for sockets bound to the IPv6 unspecified
address.

bind() and connect() should now work as expected on IPPROTO_L2TP
sockets. Extra features, like SO_REUSEADDR, remain unsupported.

The matching conditions in __l2tp_ip6_bind_lookup() and
__l2tp_ip_bind_lookup() are getting hard to read. I've kept the single
test approach to make the intend of the patches clear. I'll split the
conditionals once these fixes reach net-next.

Guillaume Nault (2):
  l2tp: consider '::' as wildcard address in l2tp_ip6 socket lookup
  l2tp: take remote address into account in l2tp_ip and l2tp_ip6 socket
    lookups
