Subject: sock_diag: do not broadcast raw socket destruction
From: Willem de Bruijn <willemb@google.com>
[ 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.
Fixes: eb4cb008529c ("sock_diag: define destruction multicast groups")
