From b1e355a76ff17a4efa164b53df9d785d966cb54c Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Fri, 31 Jan 2020 09:14:47 -0800 Subject: tcp: clear tp->total_retrans in tcp_disconnect() [ Upstream commit c13c48c00a6bc1febc73902505bdec0967bd7095 ] total_retrans needs to be cleared in tcp_disconnect(). tcp_disconnect() is rarely used, but it is worth fixing it.
