batman-adv: fix skb->data assignment

2012-07-16T16:04:11+00:00

commit 2c995ff892313009e336ecc8ec3411022f5b1c39 upstream.

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 free'd memory.

This bug was introduced by a73105b8d4c765d9ebfb664d0a66802127d8e4c7

batman-adv: convert time_after instances to has_timed_out

2012-02-16T18:50:20+00:00

To increase readability the has_timed_out() functions has been introduced.
This patch converts existing time_after() calls to use this wrapper
function (if applicable).
This patch also converts all timeouts to miliseconds to be consistent.

batman-adv: simplify bat_ogm_receive API call

2012-02-16T18:50:19+00:00

Most of the values in that call are derived from the skb, so we can hand
over the skb instead.

batman-adv: Explicitly mark the common header structure

2012-02-16T18:50:19+00:00

All batman-adv packets have a common 3 byte header. It can be used to share
some code between different code paths, but it was never explicit stated that
this header has to be always the same for all packets. Therefore, new code
changes always have the problem that they may accidently introduce regressions
by moving some elements around.

A new structure is introduced that contains the common header and makes it
easier visible that these 3 bytes have to be the same for all on-wire packets.
