From 9b0be3d2545bfd0b482883bada1f4f0410b683ef Mon Sep 17 00:00:00 2001 From: Florian Westphal Date: Tue, 12 Jan 2016 17:07:05 +0100 Subject: netfilter: ipset: allow a 0 netmask with hash_netiface type Jozsef says: The correct behaviour is that if we have ipset create test1 hash:net,iface ipset add test1 0.0.0.0/0,eth0 iptables -A INPUT -m set --match-set test1 src,src then the rule should match for any traffic coming in through eth0. This removes the -EINVAL runtime test to make matching work in case packet arrived via the specified interface.
