From 15bb7745e94a665caf42bfaabf0ce062845b533b Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Wed, 22 Mar 2017 08:10:21 -0700 Subject: tcp: initialize icsk_ack.lrcvtime at session start time icsk_ack.lrcvtime has a 0 value at socket creation time. tcpi_last_data_recv can have bogus value if no payload is ever received. This patch initializes icsk_ack.lrcvtime for active sessions in tcp_finish_connect(), and for passive sessions in tcp_create_openreq_child() Signed-off-by: Eric Dumazet Acked-by: Neal Cardwell Signed-off-by: David S.
