2012-11-07batman-adv: Add get_ethtool_stats() support for DATMartin Hundebøll
Added additional counters for D.A.T. Signed-off-by: Martin Hundebøll <martin@hundeboll.net> Signed-off-by: Antonio Quartulli <ordex@autistici.org>
2012-11-07batman-adv: Distributed ARP Table - add compile optionAntonio Quartulli
This patch makes it possible to decide whether to include DAT within the batman-adv binary or not. It is extremely useful when the user wants to reduce the size of the resulting module by cutting off any not needed feature. Signed-off-by: Antonio Quartulli <ordex@autistici.org>
2012-11-07batman-adv: Distributed ARP Table - add snooping functions for ARP messagesAntonio Quartulli
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.

2012-11-07batman-adv: Distributed ARP Table - add ARP parsing functionsAntonio Quartulli
ARP messages are now parsed to make it possible to trigger special actions depending on their types (snooping). Signed-off-by: Antonio Quartulli <ordex@autistici.org>
2012-11-07batman-adv: Distributed ARP Table - implement local storageAntonio Quartulli
Since batman-adv cannot inter-operate with the host ARP table, this patch introduces a batman-adv private storage for ARP entries exchanged within DAT. This storage will represent the node local cache in the DAT protocol. Signed-off-by: Antonio Quartulli <ordex@autistici.org>
2012-11-07batman-adv: Distributed ARP Table - create DHT helper functionsAntonio Quartulli
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>
