[B.A.T.M.A.N.] Manual route manipulation
by Bouterse, Robert 18 Jan '12

18 Jan '12

Hi, I am new to the BATMAN list, and I need some help, I am running some feasibility tests on batman-adv for our use. I need to test how well it reroutes traffic when an intermediate node goes away. I need to set up a mesh in a diamond pattern, like: |---->B<----| A<--{ }--->D |---->C<----| Then find out if traffic is being routed through the B node, shutdown the B node, and see that the route "heals" to using node C instead. I was able to do this on open80211s by using the "iw station set plink_action block" command to force the A node to never communicate directly with the D node, and wireshark to verify the communications. Does anyone know of a way of doing these types of path manipulations with batman-adv? I didn't see anything in batctl that looked like it would work. Maybe there are /sys or /proc entries? /*----------------------------------------*/ Bob Bouterse Senior Software Engineer Multimedia Development Center D&M Holdings Inc. http://www.dm-holdings.com

[B.A.T.M.A.N.] [PATCH] batman-adv: TT_CLIENT_PENDING is never set in struct tt_global_entry
by Antonio Quartulli 15 Jan '12

15 Jan '12

Actually the TT_CLIENT_PENDING flag is never set in the tt_global_entry structure, therefore this code is useless and can be removed.

Yes, we suspected it could be a TX dma problem, because occasionally we found that error in the logs, so we followed some openwrt tickets related with that, but we're not sure that's the problem, and anyway it has not been solved yet. We've also asked on ath9k list about the driver debug files in case we could find something there, but they did't answered, I guess it's hard to explain in a mail list. We haven't asked to linux-wireless, maybe it would be better, since it could be something on top of the driver. > >> > By the way, the D-Link Dir-615 is an n router, but for some reason >> > related with hostapd the ap vif gets configured in g mode, and the adhoc >> > in n mode, no matter what we set in the uci files.

We were thinking in a script that managed the stations to connect to the different APs to avoid configuring each router manually. However we realized that with just one managed interface, each router could connect to only one AP, so if we wanted that every router could connect bidirectionally to others we should use a number of managed interfaces enough to connect to all neigbours, shouldn't we? In any case it would be just another test to see if the results are different. Gabriel

The > reason is quite > simple: The larger the mesh the more outdated your information will be. That is actually acceptable and expected. I just want the information between the one-hop neighbors to be relatively timely. The only requirement for the further away robots that I have is that if the robot positions and the world are static, then the topology information should more or less stabilize over time. Random fluctuations are OK; they can be averaged away without any trouble. Does that make sense? Thanks, Cem Karan Classification: UNCLASSIFIED Caveats: NONE

[B.A.T.M.A.N.] problem with mesh network
by gtolon＠inti.gob.ar 09 Jan '12

09 Jan '12

Hi We are using batman-adv 2011.2.0 with Openwrt Backfire-rc6 on D-Link Dir-615 routers (2 Antennas, 1 single radio), each router with an adhoc interface managed by batman-adv for the mesh network and an Acces Point interface bridged with bat0 and ethernet to allow non batman-adv clients to connect. The problem is that sometimes all works fine, but sometimes we get very poor bitrates between routers, even using just two routers, testing with iperf. We don't know where the problem is, specially because it's a very erratic behavior. If any of you have used this configuration with openwrt and ath9k driver we'd really appreciate some help. By the way, the D-Link Dir-615 is an n router, but for some reason related with hostapd the ap vif gets configured in g mode, and the adhoc in n mode, no matter what we set in the uci files. So in case the problem were related with the adhoc and ap virtual interface, we were thinking about the possibility of setting the mesh network without using adhoc mode. In that case each router should have one ap for non batman-adv clients, and two additional interfaces, one in ap and the other managed, these two used to connect with other routers via batman-adv, would that be correct? In that case, you think this configuration could be more or less stable than the other using adhoc mode? Thanks in advance! Gabriel

[B.A.T.M.A.N.] statistics & topology provided by batman-adv (UNCLASSIFIED)
by Karan, Cem F CIV (US) 08 Jan '12

08 Jan '12

Classification: UNCLASSIFIED Caveats: NONE If this question is answered somewhere else, please forgive me; I spent this morning looking through documentation, but not quite finding answers to what I'm looking for. I'm a roboticist. My current project involves creating robots that are mobile ad-hoc routers for a network. The robots are supposed to autonomously determine where to move to improve the bandwidth/latency/reliability/etc. of a network. In order for this to work, each robot needs to have a rough approximation of the topology of the network, so they can measure if their movements are improving or worsening the network. The topology information needs to include not just what the network is currently like (which, from the documentation, appears to always be a tree), but a complete graph, with measured information about the bandwidth/latency/reliability of the links between pairs of nodes. Is it possible to get this information from batman-adv? Thanks, Cem Karan Classification: UNCLASSIFIED Caveats: NONE

[B.A.T.M.A.N.] [PATCH 1/2] batman-adv: set TT_CLIENT_NEW flag before invoking hash_add()
by Antonio Quartulli 08 Jan '12

08 Jan '12

In case of a new tt_local_entry, the TT_CLIENT_NEW flag has to be set before adding such entry to the hash table. Otherwise, a concurrent a tt_query_reply forging operation could select such entry (as it is already in the hash table) even if it should not.

Sadly we are still some steps away from enabling it on the device. I searched for the sysfs file and while I did this I figured out, that the patch I created was not apllied because patches for batman-adv need to have the string "batman" in their file name. So I renamed it and now it gets apllied but: now I get the compile error again I descriped already in my previos email. Here is the pastebin link from the actual compile error: http://pastebin.com/iJy2u7Ff Maybe you can take a look at it and find our mistake? This is the patch we use: http://trac.freifunk-ol.de/browser/firmware/Trunk/build_patches/bla2/0001- batman-adv-bla2.patch I made no other changes to the default files that are shipped with the latest OpenWrt release.

[B.A.T.M.A.N.] Loading the kernel module
by Rob Lourens 04 Jan '12

Hi, I'm having trouble with loading the kernel module. I'm sure it's just a dumb mistake on my part. I compiled the module, loaded it with insmod, and I can add interfaces using /sys/class/net/wlan0/batman_adv, but batctl says that the kernel module may not be loaded. It's true that there is no folder /proc/net/batman-adv. rob@ubuntu:/usr/src/batman-adv-2011.4.0$ sudo insmod batman-adv.ko [sudo] password for rob: rob@ubuntu:/usr/src/batman-adv-2011.4.0$ lsmod | grep batman batman_adv 83597 0 rob@ubuntu:/usr/src/batman-adv-2011.4.0$ sudo batctl if Error - the folder '/proc/net/batman-adv/' was not found within the proc filesystem Please make sure that the batman-adv kernel module is loaded rob@ubuntu:/usr/src/batman-adv-2011.4.0$ uname --all Linux ubuntu 2.6.32-33-generic #70-Ubuntu SMP Thu Jul 7 21:09:46 UTC 2011 i686 GNU/Linux rob@ubuntu:/usr/src/batman-adv-2011.4.0$ modinfo batman-adv filename: /lib/modules/2.6.32-33-generic/updates/dkms/batman-adv.ko version: 0.2 description: B.A.T.M.A.N. advanced author: Marek Lindner <lindner_marek(a)yahoo.de>, Simon Wunderlich <siwu(a)hrz.tu-chemnitz.de> license: GPL srcversion: CE6165E01E79C5D87404D6F depends: vermagic: 2.6.32-33-generic SMP mod_unload modversions 586 Any idea what I am missing? Thanks, Rob Lourens
