2012-11-30batman-adv: use ETH_P_BATMANAntonio Quartulli1-1/+2
The ETH_P_BATMAN ethertype is now defined kernel-wide. Use it instead of the private BATADV_ETH_P_BATMAN define. Signed-off-by: Antonio Quartulli <ordex@autistici.org> Signed-off-by: Marek Lindner <lindner_marek@yahoo.de>

hard-interface Any virtual device created on top of a batman-adv mesh interface must be prevented to be used to create a new mesh network (this would lead to an unwanted batman-over-batman configuration) Signed-off-by: Antonio Quartulli <ordex@autistici.org>

Add all the relevant functions in order to manage a Distributed Hash Table over the B.A.T.M.A.N.-adv network. It will later be used to store several ARP entries and implement DAT (Distributed ARP Table) Signed-off-by: Antonio Quartulli <ordex@autistici.org>

2012-08-23batman-adv: Split batadv_priv in sub-structures for featuresSven Eckelmann1-2/+3
The structure batadv_priv grows everytime a new feature is introduced. It gets hard to find the parts of the struct that belongs to a specific feature. This becomes even harder by the fact that not every feature uses a prefix in the member name. The variables for bridge loop avoidence, gateway handling, translation table and visualization server are moved into separate structs that are included in the bat_priv main struct.

2012-08-23batman-adv: check batadv_orig_hash_add_if() return codeSimon Wunderlich1-1/+7
If this call fails, some of the orig_nodes spaces may have been resized for the increased number of interface, and some may not. If we would just continue with the larger number of interfaces, this would lead to access to not allocated memory later. We better check the return code, and don't add the interface if no memory is available. OTOH, keeping some of the orig_nodes with too much memory allocated should hurt no one (except for a few too many bytes allocated).

2012-07-02batman-adv: Remove bat_ prefix from bat_{debugfs, sysfs}.{c, h}Sven Eckelmann1-1/+1
The "bat_" prefix in the source files implementing the batman-adv sysfs and debugfs interface doesn't have a special meaning and are only used by these files and files that implement the actual B.A.T.M.A.N. path finding algorithm. The prefix is better suited to mark files that are used to implement the main part of the path finding. All other files should not use it and therefore gets renamed.

2012-04-11batman-adv: add basic bridge loop avoidance codeSimon Wunderlich1-7/+11
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.

2012-02-16batman-adv: Explicitly mark the common header structureSven Eckelmann1-3/+3
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.
