Subject: [GIT PULL net-next 01/17] ndisc: Fix size calculation for headers.
Date: Tue, 18 Dec 2012 19:52:04 +0900 [thread overview]
Message-ID: <50D04AD4.8010908@linux-ipv6.org> (raw)
In-Reply-To: <50CF84A5.7030706@linux-ipv6.org>
We used to allocate MAX_HEADER bytes more than needed but
reserved hlen only (not MAX_HEADER + hlen) and the MAX_HEADER
was left behind.
