Subject: [PATCH AUTOSEL 4.19 524/671] netfilter: ctnetlink: honor IPS_OFFLOAD flag
Date: Thu, 16 Jan 2020 12:02:42 -0500
Message-ID: <20200116170509.12787-261-sashal@kernel.org> (raw)
In-Reply-To: <20200116170509.12787-1-sashal@kernel.org>

From: Pablo Neira Ayuso <pablo@netfilter.org>

[ Upstream commit b067fa009c884401d23846251031c1f14d8a9c77 ]

If this flag is set, timeout and state are irrelevant to userspace.

Fixes: 90964016e5d3 ("netfilter: nf_conntrack: add IPS_OFFLOAD status bit")
