l2tp: fix info leak in l2tp_ip6_recvmsg() The L2TP code for IPv6 fails to initialize the l2tp_conn_id member of struct sockaddr_l2tpip6 and therefore leaks four bytes kernel stack in l2tp_ip6_recvmsg() in case msg_name is set. Initialize l2tp_conn_id with 0 to avoid the info leak. Signed-off-by: Mathias Krause <minipli@googlemail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
