From aa667cf34139a9eebcbf4e4b0e45a38da857b09a Mon Sep 17 00:00:00 2001 From: Ivan Shvedunov Date: Fri, 24 Jul 2020 19:16:28 +0300 Subject: [PATCH 2/2] Fix initializing elog track for accepted TCP connections When TCP debugging is enabled, the code was crashing because tcp_send_synack (child) was called before TCP_EVT (TCP_EVT_SYN_RCVD, child, 1) which initializes the elog track.
