From b47342e6341d706844b9cb2ce436f2eb80601543 Mon Sep 17 00:00:00 2001 From: Eelco Chaudron Date: Tue, 1 Sep 2020 16:56:02 +0200 Subject: [PATCH] netfilter: conntrack: nf_conncount_init is failing with IPv6 disabled [ Upstream commit 526e81b990e53e31ba40ba304a2285ffd098721f ] The openvswitch module fails initialization when used in a kernel without IPv6 enabled. nf_conncount_init() fails because the ct code unconditionally tries to initialize the netns IPv6 related bit, regardless of the build option. The change below ignores the IPv6 part if not enabled. Note that the corresponding _put() function already has this IPv6 configuration check.
