From 7c3d5ab1f35f5475b1a1fbe74143683cfc092d33 Mon Sep 17 00:00:00 2001 From: Vasily Averin Date: Sat, 3 May 2014 03:14:04 +0400 Subject: [PATCH] ipv4: fix "conntrack zones" support for defrag user check in ip_expire Defrag user check in ip_expire was not updated after adding support for "conntrack zones". This bug manifests as a RFC violation, since the router will send the icmp time exceeeded message when using conntrack zones.
