[B.A.T.M.A.N.] Batman-adv secure
by Filippo Sallemi 05 Oct '11

05 Oct '11

Hi all, I don't known if this is a old argument but exsist the possibility to implement a secure mesh network? For example a tecnique that crypt batman-adv traffic with a preshare key or similar or using ebtables to block all INPUT and OUTPUT traffic and allow only the specified nodes mac?

[B.A.T.M.A.N.] batman-adv: loop caused by tinc and wifi
by Bjoern Franke 29 Sep '11

29 Sep '11

Hi, we are using the following configuration in our freifunk network: B.A.T.M.A.N. advanced 2011.0.0 (compatibility version 12) ath1 (ad-hoc) as batman-adv-interfaces ath0 (ap), tap0, eth0.1 and bat0 as a bridge stp is enabled for the bridge. Most of the nodes are connected via tinc and the network runs fine. But if two nodes which have a tinc connection also get a ath1-connection, the whole network crashes. What are we doing wrong? regards Bjoern -- jabber: bjo(a)schafweide.org bjo.nord-west.org | nord-west.org | freifunk-ol.de

Hi David, our testers have discovered a regression in the current linux-3.1 code base. It increases latency of payload traffic by a factor of 4-5. Therefore we propose a patch that hopefully can be included before linux 3.1 final has been released. We kept it as short as possible to avoid introducing last minute bugs. Once you pulled the patch you will run into a merge conflict with net-next: ++<<<<<<< HEAD + orig_node = transtable_search(bat_priv, ethhdr->h_source, + ethhdr->h_dest); + if (is_multicast_ether_addr(ethhdr->h_dest) || + (orig_node && orig_node->gw_flags)) { ++======= + orig_node = transtable_search(bat_priv, ethhdr->h_dest); + do_bcast = is_multicast_ether_addr(ethhdr->h_dest); + if (do_bcast || (orig_node && orig_node->gw_flags)) { ++>>>>>>> batman-adv/maint The correct merge result would be: +====== orig_node = transtable_search(bat_priv, ethhdr->h_source, ethhdr->h_dest); do_bcast = is_multicast_ether_addr(ethhdr->h_dest); if (do_bcast || (orig_node && orig_node->gw_flags)) { +====== Let me know if there is a better way to address the merge conflict.

I'm going to send to the ml a patch that will enable a more verbose log so that we can obtain more information in one shot. Please apply that patch on top of the master branch (it should be easy with openwrt. Ask here if you have problems). Then, it would be nice if you could copy & paste here the log obtained from two not working nodes. Once you will post the logs we will decide how to further inspect the problem. Unluckily it seems to be a arch (or what else) related problem which makes it unreproducible with my (our) routers. Cheers, 1) the patch will follow in this thread. 2) I think it is easier to read the log than inspect the graph data 3) I just noticed this was a private mail. Please keep the conversation public so that all the other people can contribute to solve the issue ;);) -- Antonio Quartulli ..each of us alone is worth nothing.. Ernesto "Che" Guevara

Hi, here comes the next batch batch I'd like to get the pulled into net-next-2.6/3.2. These patches mainly focus restructering the routing code in order to allow the kernel module the handling of the current routing algorithm and the upcoming one. To ensure a smooth transition and efficient testing later, we decided to offer a choice of routing algorithm but have not come to a final decision on how to design this choice yet. It either will be a compile time option, a module parameter or a runtime switch. Any suggestions / best practice tips ? Note: The new algorithm has been designed with backward compatibility in mind (using TLVs). We are trying to address the incompatibility issue you and others have pointed out.
