[IPV6]: Mischecked tw match in __inet6_check_established.
When looking for a conflicting connection the !sk->sk_bound_dev_if check is performed only for live sockets, but not for timewait-ed. This is not the case for ipv4, for __inet6_lookup_established in both ipv4 and ipv6 and for other places that check for tw-s. Was this missed accidentally? If so, then this patch fixes it and besides makes use if the dif variable declared in the function. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S.
