Subject: [PATCH] netfilter: ipset: fix netiface set name overflow
Date: Tue, 27 Nov 2012 02:03:05 +0100 [thread overview]
Message-ID: <1353978185-3564-2-git-send-email-pablo@netfilter.org> (raw)
In-Reply-To: <1353978185-3564-1-git-send-email-pablo@netfilter.org>
From: Florian Westphal <fw@strlen.de>
attribute is copied to IFNAMSIZ-size stack variable,
but IFNAMSIZ is smaller than IPSET_MAXNAMELEN.
Fortunately nfnetlink needs CAP_NET_ADMIN.
