Subject: [PATCH AUTOSEL 5.5 002/121] netfilter: ctnetlink: be more strict when NF_CONNTRACK_MARK is not set
Date: Sat, 11 Apr 2020 19:05:07 -0400	[thread overview]
Message-ID: <20200411230706.23855-2-sashal@kernel.org> (raw)
In-Reply-To: <20200411230706.23855-1-sashal@kernel.org>

From: Romain Bellan <romain.bellan@wifirst.fr>

[ Upstream commit 7c6b4121627aeaa79536fbb900feafec740410d3 ]

When CONFIG_NF_CONNTRACK_MARK is not set, any CTA_MARK or CTA_MARK_MASK
in netlink message are not supported. We should return an error when one
of them is set, not both

Fixes: 9306425b70bf ("netfilter: ctnetlink: must check mark attributes vs NULL")
