parent[SCTP]: extend exported data in /proc/net/sctp/assoc (diff)
[INET]: Remove struct dst_entry *dst from request_sock_ops.rtx_syn_ack.
It looks like dst parameter is used in this API due to historical reasons. Actually, it is really used in the direct call to tcp_v4_send_synack only. So, create a wrapper for tcp_v4_send_synack and remove dst from rtx_syn_ack. Signed-off-by: Denis V. Lunev <den@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
