Neal Cardwell 02cf4ebd82 tcp: initialize passive-side sk_pacing_rate after 3WHS ... For passive TCP connections, upon receiving the ACK that completes the 3WHS, make sure we set our pacing rate after we get our first RTT sample. On passive TCP connections, when we receive the ACK completing the 3WHS we do not take an RTT sample in tcp_ack(), but rather in tcp_synack_rtt_meas(). So upon receiving the ACK that completes the 3WHS, tcp_ack() leaves sk_pacing_rate at its initial value. Originally the initial sk_pacing_rate value was 0, so passive-side connections defaulted to sysctl_tcp_min_tso_segs (2 segs) in skbuffs made in the first RTT. With a default initial cwnd of 10 packets, this happened to be correct for RTTs 5ms or bigger, so it was hard to see problems in WAN or emulated WAN testing. Since 7eec4174ff ("pkt_sched: fq: fix non TCP flows pacing"), the initial sk_pacing_rate is 0xffffffff. So after that change, passive TCP connections were keeping this value (and using large numbers of segments per skbuff) until receiving an ACK for data.
