ip_queue_xmit() assumes the skb it has to transmit is attached to an inet socket. Commit31c70d5956("l2tp: keep original skb ownership") changed l2tp to not change skb ownership and thus broke this assumption. One fix is to add a new 'struct sock *sk' parameter to ip_queue_xmit(), so that we do not assume skb->sk points to the socket used by l2tp tunnel.
