Subject: [PATCH 4/5] netfilter: ctnetlink: honor IPS_OFFLOAD flag
Date: Wed,  4 Sep 2019 21:36:45 +0200	[thread overview]
Message-ID: <20190904193646.23830-5-pablo@netfilter.org> (raw)
In-Reply-To: <20190904193646.23830-1-pablo@netfilter.org>

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

Fixes: 90964016e5d3 ("netfilter: nf_conntrack: add IPS_OFFLOAD status bit")
Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
