batman-adv: 32bit sequence number and TTL for broadcasts
From: Simon Wunderlich <simon.wunderlich(a)s2003.tu-chemnitz.de>
This patch changes the sequence number range from 8 or 16 bit to 32 bit.
This should avoid problems with the sequence number sliding window algorithm
which we had seen in the past for broadcast floods or malicious packet
injections. We can not assure 100% security with this patch, but it is quite
an improvement over the old 16 bit sequence numbers:
* expected window size can be increased (4096 -> 65536)
* 64k packets in the right order would now be needed to cause a loop,
which seems practically impossible.
Furthermore, a TTL field has been added to the broadcast packet type, just to
make sure.
These changes required to increase the compatibility level once again.

Simon Wunderlich:
These changes required to increase the compatibility level once again.
It should therefore only applied to the upcoming 0.3 branch.

batman-adv: Update pointer to ethhdr after skb_copy
We must ensure that all pointer to a socket buffer are updated when we
copy a socket buffer and free our reference to the old one.
Another part of the kernel could also free its reference which maybe
removes the buffer completely. In that situation we would would feed
wrong information to the routing algorithm after the memory area is
written again by someone else.

batman-adv: move queue counters into bat_priv
to support multiple mesh devices later, we need to move global variables
like the queues into corresponding private structs bat_priv of the soft
devices.
Note that this patch still has a lot of FIXMEs and depends on the global
soft_device variable. This should be resolved later, e.g. by referencing
the parent soft device in batman_if.

batman-adv: Limit queue lengths for batman and broadcast packets
This patch limits the queue lengths of batman and broadcast packets. BATMAN
packets are held back for aggregation and jittered to avoid interferences.
Broadcast packets are stored to be sent out multiple times to increase
the probability to be received by other nodes in lossy environments.
Especially in extreme cases like broadcast storms, the queues have been seen
to run full, eating up all the memory and triggering the infamous OOM killer.
With the queue length limits introduced in this patch, this problem is
avoided.
Each queue is limited to 256 entries for now, resulting in 1 MB of maximum
space available in total for typical setups (assuming one packet including
overhead does not require more than 2000 byte). This should also be reasonable
for smaller routers, otherwise the defines can be tweaked later.
This third version of the patch does not increase the local broadcast
sequence number when the queue is already full.
