From b89d15480d0cacacae1a0fe0b3da01b529f2914f Mon Sep 17 00:00:00 2001 From: Stefano Brivio Date: Mon, 24 Jun 2019 15:20:11 +0200 Subject: [PATCH] netfilter: ipset: Actually allow destination MAC address for hash:ip,mac sets too In commit 8cc4ccf58379 ("ipset: Allow matching on destination MAC address for mac and ipmac sets"), ipset.git commit 1543514c46a7, I removed the KADT check that prevents matching on destination MAC addresses for hash:mac sets, but forgot to remove the same check for hash:ip,mac set. Drop this check: functionality is now commented in man pages and there's no reason to restrict to source MAC address matching anymore.
