4.6-stable review patch. If anyone has any objections, please let me know. ------------------ From: Willem de Bruijn <willemb@xxxxxxxxxx> [ Upstream commit 9a0fee2b552b1235fb1706ae1fc664ae74573be8 ] Diag intends to broadcast tcp_sk and udp_sk socket destruction. Testing sk->sk_protocol for IPPROTO_TCP/IPPROTO_UDP alone is not sufficient for this. Raw sockets can have the same type. Add a test for sk->sk_type.
