inet: Fix virt-manager regression due to bind(0) changes.
From: Stephen Hemminger <shemminger@vyatta.com> Fix regression introduced by a9d8f9110d7e953c2f2b521087a4179677843c2a ("inet: Allowing more than 64k connections and heavily optimize bind(0) time.") Based upon initial patches and feedback from Evegniy Polyakov and Eric Dumazet. From Eric Dumazet: -------------------- Also there might be a problem at line 175 if (sk->sk_reuse && sk->sk_state != TCP_LISTEN && --attempts >= 0) { spin_unlock(&head->lock); goto again; If we entered inet_csk_get_port() with a non null snum, we can "goto again" while it was not expected. -------------------- Signed-off-by: David S. Miller <davem@davemloft.net>
