[PATCH 0/5] tcp: ipv4 listen state scaling

[Dmitry Popov]

*Note: this patch depends on "[PATCH] tcp: md5 signature check scaling"*
Hi.

The problem with current TCP stack implementation is that it locks
socket in tcp_v4_rcv on each incoming packet. However, incoming SYNs
may be processed in parallel with syncookies. And it helps a lot under
synflood. This proposed patch serie fixes this problem, but (as for
now) for ipv4 only.
6-core Xeon with 6 RX queues on NIC:
without patch: 530k syn-pkts/s;
with patch: 1620k syn-pkts/s.
