batman-adv; branch, maint, updated. v2012.2.0-1-gc7d05ee
by postmaster＠open-mesh.org
The following commit has been merged in the maint branch:
commit c7d05ee2b60370392d9c7bb1b764fd36b5aec81b
Author: Antonio Quartulli <ordex(a)autistici.org>
Date: Thu Jun 14 22:21:28 2012 +0200
batman-adv: fix skb->data assignment
skb_linearize(skb) possibly rearranges the skb internal data and then changes
the skb->data pointer value. For this reason any other pointer in the code that
was assigned skb->data before invoking skb_linearise(skb) must be re-assigned.
In the current tt_query message handling code this is not done and therefore, in
case of skb linearization, the pointer used to handle the packet header ends up
in pointing to poisoned memory. The packet is then dropped but the
translation-table mechanism is corrupted.
