[B.A.T.M.A.N.] [PATCHv5 0/9] DAT: Distributed ARP Table
by Antonio Quartulli 16 Feb '12

16 Feb '12

Hello people, **** This is the **fifth** version of this patchset. The whole code has been reviewed after some discussions on irc and here in the ml in the previous threads. Several bugs have been spotted and fixed. Thanks Marek, Sven, Simon, Andrew and all the others for the comments/feedbacks. This patchset assumes that patch [PATCH] batman-adv: add biggest_unsigned_int(x) macro has already been applied **** For details about the DAT mechanism, please refer to the preliminary documentation that has already been put on the wiki[1]. A more exhaustive and detailed documentation is going to come soon. PatchsetV5 Additions: ------------------------ - Sanity check for ARP messages (messages containing multicast/loopback addresses are ignored) - A new unicast packet type has been introduced (UNICAST_4ADDR), which contains the originator address and the payload type. - Thanks to this new packet type, more and more debugging messages have been added. In this way it is easier to track the behaviour of DAT and it is possible to understand who and why added a given entry in the soft_iface ARP table.

[B.A.T.M.A.N.] B.A.T.M.A.N. V - the next steps
by Marek Lindner 12 Feb '12

12 Feb '12

Hi folks, after having the B.A.T.M.A.N. IV routing code moved into one single file, a preliminary routing protocol API and an easy to use routing protocol switch it is time to move forward with B.A.T.M.A.N. V. B.A.T.M.A.N. V is going to split the various tasks handled by the B.A.T.M.A.N. IV OGM protocol into subprotocols which will allow us to optimize each protocol much better. The ELP protocol is the first of these subprotocols to come. The initial ideas surrounding this protocol type are more than 2-3 years old. At some point Linus was the driving force behind the protocol development. Thanks to him we have proper documentation[1] as well as some code in his repository[2] (still called ndp). I began rebasing and integrating his code [3]. It will take a couple of patch series to get the API and the old ELP code base into shape. Cheers, Marek [1] http://www.open-mesh.org/wiki/batman-adv/ELP [2] http://git.open-mesh.org/?p=t_x/batman-adv.git;a=summary [3] http://git.open-mesh.org/?p=marek/batman-adv.git;a=summary

Any particular reason that you always email me privately ? At this point it would be better to discuss a possible solution first. What if your patch does not work ? We can save time by talking about a solution before implementing it. Regards, Marek

[B.A.T.M.A.N.] [PATCH] batman-adv: Fix daily check regression in blaII
by Sven Eckelmann 11 Feb '12

11 Feb '12

9fd6b0615b5499b270d39a92b8790e206cf75833 introduced some regressions in the daily checks on open-mesh.org. Those were only visible when CONFIG_BATMAN_ADV_BLA was disabled. 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.
