From 375fe02c91792917aa26d68a87ab110d1937f44e Mon Sep 17 00:00:00 2001 From: Yuchung Cheng <ycheng@google.com> Date: Mon, 22 Jul 2013 16:20:45 -0700 Subject: tcp: consolidate SYNACK RTT sampling The first patch consolidates SYNACK and other RTT measurement to use a central function tcp_ack_update_rtt(). A (small) bonus is now SYNACK RTT measurement happens after PAWS check, potentially reducing the impact of RTO seeding on bad TCP timestamps values.
