Subject: [PATCH 5/5] netfilter: nf_flow_table: set default timeout after successful insertion
Date: Wed,  4 Sep 2019 21:36:46 +0200
Message-ID: <20190904193646.23830-6-pablo@netfilter.org> (raw)
In-Reply-To: <20190904193646.23830-1-pablo@netfilter.org>

Set up the default timeout for this new entry otherwise the garbage
collector might quickly remove it right after the flowtable insertion.

Fixes: ac2a66665e23 ("netfilter: add generic flow table infrastructure")
