From c125e80b88687b25b321795457309eaaee4bf270 Mon Sep 17 00:00:00 2001 From: Craig Gallek Date: Wed, 10 Feb 2016 11:50:40 -0500 Subject: soreuseport: fast reuseport TCP socket selection This change extends the fast SO_REUSEPORT socket lookup implemented for UDP to TCP. Listener sockets with SO_REUSEPORT and the same receive address are additionally added to an array for faster random access. This means that only a single socket from the group must be found in the listener list before any socket in the group can be used to receive a packet. Previously, every socket in the group needed to be considered before handing off the incoming packet. This feature also exposes the ability to use a BPF program when selecting a socket from a reuseport group. Signed-off-by: Craig Gallek Signed-off-by: David S.
