[SCTP] bug: sctp_assoc_lookup_laddr() is broken with ipv6.
It expects (and gets) laddr with net-endian sin_port. And then it calls sctp_bind_addr_match(), which *does* care about port numbers in case of ipv6 and expects them to be host-endian. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: David S. Miller <davem@davemloft.net>
