batman-adv: improve unicast packet (re)routing
In case of a client X roaming from a generic node A to another node B, it is possible that a third node C gets A's OGM but not B's. At this point in time, if C wants to send data to X it will send a unicast packet destined to A. The packet header will contain A's last ttvn (C got A's OGM and so it knows it).
The packet will travel towards A without being intercepted because the ttvn contained in its header is the newest for A.
Once A will receive the packet, A's state will not report to be in a "roaming phase" (because, after a roaming, once A sends out its OGM, all the changes are committed and the node is considered not to be in the roaming state anymore) and it will match the ttvn carried by the packet. Therefore there is no reason for A to try to alter the packet's route, thus dropping the packet because the destination client is not there anymore.
However, C is well aware that it's routing information towards the client X is outdated as it received an OGM from A saying that the client roamed away. Thanks to this detail, this patch introduces a small change in behaviour: as long as C is in the state of not knowing the new location of client X it will forward the traffic to its last known location using ttvn-1 of the destination. By using an older ttvn node A will be forced to re-route the packet. Intermediate nodes are also allowed to update the packet's destination as long as they have the information about the client's new location.

batman-adv: avoid temporary routing loops by being strict on forwarded OGMs
batman-adv would forward OGMs from non-besthops while replacing the the TQ and TTL values with the values from the best hop. In certain corner cases this leads to a temporary routing loop. This patch changes this behavior: Only packets from best next hops are forwarded - TQ and TTL values won't be replaced anymore. However, the protocol needs to rebroadcast OGMs from single hop neighbors regardless of whether or not they are the best hop. To handle this case a new flag is introduced to alert neighboring nodes about the forwarded OGM that is not from my best next hop. It is to be discarded by all nodes except for the one originating the OGM.

This allows us to easily add a sysfs parameter for an unsigned int later, which is not for a batman mesh interface (e.g. bat0), but for a common interface instead. It allows reading and writing an atomic_t in hard_iface (instead of bat_priv compared to the mesh variant).

batman-adv: Distributed ARP Table - add snooping functions for ARP messages
In case of an ARP message going in or out the soft_iface, it is intercepted and a special action is performed. In particular the DHT helper functions previously implemented are used to store all the ARP entries belonging to the network in order to provide a fast and unicast lookup instead of the classic broadcast flooding mechanism. Each node stores the entries it is responsible for (following the DHT rules) in its soft_iface ARP table. This makes it possible to reuse the kernel data structures and functions for ARP management.

batman-adv: add UNICAST_4ADDR packet type
The current unicast packet type does not contain the orig source address. This patches add a new unicast packet (called UNICAST_4ADDR) which provides two new fields: the originator source address and the subtype (the type of the data contained in the packet payload). The former is useful to identify the node which injected the packet into the network and the latter is useful to avoid creating new unicast packet types in the future: a macro defining a new subtype will be enough.

batman-adv: skip the window protection test when the originator has no neighbours
When we receive an OGM from from a node for the first time, the last_real_seqno field of the orig_node structure has not been initialised yet. The value of this field is used to compute the current ogm-seqno window and therefore the protection mechanism will probably drop the packet due to an out-of-window error. To avoid this situation this patch adds a check to skip the window protection mechanism if no neighbour nodes have already been added. When the first neighbour node is added, the last_real_seqno field is initialised too.

The reason was the usage of defines to replace the calls for not available functions. The actual c compiler is not able to distinguish between the used and unused variables because it doesn't see the function call anymore. The second problem was the use of simple subscopes where "do {} while(0)" whould have been necessary.

batman-adv: form groups in the bridge loop avoidance
backbone gateways may be part of the same LAN, but participate in different meshes. With this patch, backbone gateways form groups by applying the groupid of another backbone gateway if it is higher. After forming the group, they only accept messages from backbone gateways of the same group.

batman-adv: add broadcast duplicate check
When multiple backbone gateways relay the same broadcast from the backbone into the mesh, other nodes in the mesh may receive this broadcast multiple times. To avoid this, the crc checksums of received broadcasts are recorded and new broadcast packets with the same content may be dropped if received by another gateway.

batman-adv: don't let backbone gateways exchange tt entries
As the backbone gateways are connected to the same backbone, they should announce the same clients on the backbone non-exclusively.

batman-adv: allow multiple entries in tt_global_entries
as backbone gateways will all independently announce the same clients, also the tt global table must be able to hold multiple originators per client entry.
Signed-off-by: Simon Wunderlich siwu@hrz.tu-chemnitz.de --- [2011-10-30] recalculate global crc in any case:
this should not be required, but the crc diverges for some reason. Need to dig into this further ...
[2011-12-27] fix alignment
[2012-01-16] Changes after discussion with Antonio:
* Roaming flag should only be set when the last entry moved * clean up tt_global_add()
[2012-01-22] Changes after local testing:
* remove (debug) crc global computation - it breaks more than it helps * add debug message when committed locally

batman-adv: add basic bridge loop avoidance code
This second version of the bridge loop avoidance for batman-adv avoids loops between the mesh and a backbone (usually a LAN).
By connecting multiple batman-adv mesh nodes to the same ethernet segment a loop can be created when the soft-interface is bridged into that ethernet segment. A simple visualization of the loop involving the most common case - a LAN as ethernet segment:
node1 <-- LAN --> node2 | | wifi <-- mesh --> wifi
Packets from the LAN (e.g. ARP broadcasts) will circle forever from node1 or node2 over the mesh back into the LAN.
With this patch, batman recognizes backbone gateways, nodes which are part of the mesh and backbone/LAN at the same time. Each backbone gateway "claims" clients from within the mesh to handle them exclusively. By restricting that only responsible backbone gateways may handle their claimed clients traffic, loops are effectively avoided.
