[B.A.T.M.A.N.] [PATCH] batman-adv: aggregation checks should use the primary_if pointer
by Marek Lindner 04 Jul '11

04 Jul '11

The packet aggregation needs to ensure that only compatible packets are aggregated. Some of the checks are based on the interface number while assuming that the first interface also is the primary interface which is not always the case. This patch addresses the issue by using the primary_if pointer.

[B.A.T.M.A.N.] [PATCH] batman-adv: broadcast primary OGM on all active hard-interfaces
by Marek Lindner 04 Jul '11

04 Jul '11

The primary interface OGM has to be broadcasted on all hard-interfaces even if the primary interface is not the first interface (if_num = 0). Therefore the code has to compare the originating interface with the primary interface instead of checking the if_num.

[B.A.T.M.A.N.] batman-adv 2011.1.0 network interface setup
by Max Ip 27 Jun '11

27 Jun '11

Hi all, I setup the virtual interface bat0 which embeds wlan0 for my system. As described in the batman-adv README file, I did # insmod batman-adv.ko and # echo bat0 > /sys/class/net/wlan0/batman_adv/mesh_iface I can thus enable bat0 interface and start the batman-adv protocol in multihop environment. However, when I restart the computer, I need to again load the kernel module and start the process from beginning. I would like to run bat0 interface directly after restarting the computer (like we have it for wlan0 or eth0) Could you please help me how do I do this? Thanks in advance Max

[B.A.T.M.A.N.] [PATCH 0/3] Implement the AP-Isolation mechanism
by Antonio Quartulli 26 Jun '11

26 Jun '11

This patchset introduces the AP-isolation functionality. As for common access points, the AP-isolation is a mechanism that prevents clients to communicate to each other. In batman-adv the AP-isolation, if activated, will prevent "WIFI bridged-in clients" to communicate with any other "WIFI bridged-in client". The first patch introduces a mechanism which permit to detect the interface type used by a client and to possibly mark its tt_local_entry in case of WIFI. This information is then spread over the network within the TT announcements. The other two patches implement the AP-isolation mechanism which exploits the WIFI mark (on tt_entries) to prevent communications between WIFI clients. The "AP-isolation check" is done either on the receiver and on the sender side. Best regards, Antonio Quartulli

[B.A.T.M.A.N.] [PATCH] batman-adv: unify flags for tt_change/tt_local_entry/tt_global_entry
by Antonio Quartulli 26 Jun '11

26 Jun '11

The tt_local_entry structure now has a 'flags' field. This helps to unify the flags format to all the client related structures (tt_global_entry and tt_change). The 'never_purge' field is now encoded in the 'flags' one. Moreover 'enum tt_change_flags' is now called 'enum tt_client_flags' and the defined values apply to the tt_local_entry, tt_global_entry and the tt_change 'flags' field.

I cannot speak on behalf of the batman-adv developers due to conflicts in the opinion about the ongoing development. The batman-adv module is still maintained by Marek Lindner and Simon Wunderlich. Those are the main persons behind the visions of batman-adv. Therefore, the state of module hasn't changed.

This decission was made in context of the changes which are on the horizon. I personally don't know what is coming, but that many things are changing in an incompatible way.
