Subject: [PATCH nf] netfilter: nf_nat: handle NF_DROP from nfnetlink_parse_nat_setup()
Date: Fri,  9 Sep 2016 15:38:12 +0200	[thread overview]
Message-ID: <1473428292-24728-1-git-send-email-pablo@netfilter.org> (raw)

nf_nat_setup_info() returns NF_* verdicts, so convert them to error
codes that is what ctnelink expects. This has passed overlook without
having any impact since this nf_nat_setup_info() has always returned
NF_ACCEPT so far. Since 870190a9ec90 ("netfilter: nat: convert nat bysrc
hash to rhashtable"), this is problem.
