Subject: [PATCH 1/3] netfilter: ipset: Actually allow destination MAC address for hash:ip,mac sets too
Date: Mon, 29 Jul 2019 21:33:52 +0200 [thread overview]
Message-ID: <20190729193354.26559-2-kadlec@blackhole.kfki.hu> (raw)
In-Reply-To: <20190729193354.26559-1-kadlec@blackhole.kfki.hu>
From: Stefano Brivio <sbrivio@redhat.com>
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.
