Subject: [PATCH AUTOSEL 5.2 055/123] netfilter: ipset: Actually allow destination MAC address for hash:ip,mac sets too
Date: Tue, 13 Aug 2019 22:09:39 -0400 [thread overview]
Message-ID: <20190814021047.14828-55-sashal@kernel.org> (raw)
In-Reply-To: <20190814021047.14828-1-sashal@kernel.org>
From: Stefano Brivio <sbrivio@redhat.com>
[ Upstream commit b89d15480d0cacacae1a0fe0b3da01b529f2914f ]
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.
