| | | | | | | | | | | batman-adv can be compiled as part of the kernel instead of an module. In that case the linker will see all non-static symbols of batman-adv and all other non-static symbols of the kernel. This could lead to symbol collisions.

* batman-adv: turn tt commit code into routing protocol agnostic APIMarek Lindner2012-06-181-5/+9
| | | | | | | | | | | | Prior to this patch the translation table code made assumptions about how the routing protocol works and where its buffers are stored (to directly modify them). Each protocol now calls the tt code with the relevant pointers, thereby abstracting the code.

* batman-adv: Add get_ethtool_stats() supportMartin Hundebøll2012-06-181-1/+9
| | | | | | | | | | | | | | | | | | | Added additional counters in a bat_stats structure, which are exported through the ethtool api. The counters are specific to batman-adv and includes: forwarded packets and bytes management packets and bytes (aggregated OGMs at this point) translation table packets New counters are added by extending "enum bat_counters" in types.h and adding corresponding descriptive string(s) to bat_counters_strings in soft-iface.c. Counters are increased by calling batadv_add_counter() and incremented by one by calling batadv_inc_counter().

| | | | | | | | | | In the code we neever need to atomically check and set the bat_priv->tt_crc field value. It is simply set and read once in different pieces of the code.

* batman-adv: avoid temporary routing loops by being strict on forwarded OGMsMarek Lindner2012-05-111-29/+31
| | | | | | | | | | | | | | | | | 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.

* batman-adv: skip the window protection test when the originator has no ↵Antonio Quartulli2012-04-181-1/+2
| | | | | | | | | | | | | | | 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. Reported-by: Marek Lindner <lindner_marek@yahoo.de> Signed-off-by: Antonio Quartulli <ordex@autistici.org>
* batman-adv: print OGM seq numbers as unsigned intAntonio Quartulli2012-04-181-4/+4

* batman-adv: Explicitly mark the common header structureSven Eckelmann2012-02-161-23/+24
| | | | | | | | | | | | | | 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.
