Hi,
I'm evaluating the possibility to use batman in our next product (measurement equipment) and I'm facing problems in using batman. I have five nodes installed around and I experience black-outs in connection among nodes. The resoult is I can't ping a certain node anymore.
Here is the output from 'batctl o' and the subsequent ping to a node which has good link quality (TQ):
[root@gtam00119 ~]# batctl o [B.A.T.M.A.N. adv 2011.4.0, MainIF/MAC: ra0/48:5d:60:b8:a2:f6 (bat0)] Originator last-seen (#/255) Nexthop [outgoingIF]: Potential nexthops ... 48:5d:60:b8:a2:b7 0.974s (202) 48:5d:60:b8:a3:0e [ ra0]: 48:5d:60:b8:a2:d2 ( 0) 48:5d:60:b8:a3:0e (202) 48:5d:60:b8:a3:0e 0.439s (249) 48:5d:60:b8:a3:0e [ ra0]: 48:5d:60:b8:a2:d2 (231) 48:5d:60:b8:a3:0e (249) 48:5d:60:b8:a2:d2 0.749s (250) 48:5d:60:b8:a2:d2 [ ra0]: 48:5d:60:b8:a3:0e (235) 48:5d:60:b8:a2:d2 (250) 48:5d:60:b8:a2:ff 0.156s (209) 48:5d:60:b8:a3:0e [ ra0]: 48:5d:60:b8:a2:d2 ( 0) 48:5d:60:b8:a3:0e (209)

And this is the output from 'batctl ll tt routes' from he node that is being pinged (see above):

This situation was triggered by the following procedure: 1) from node (last two octets) 'a2:f6' the 'a3:0e' node was pinged 2) in the middle a ssh connection from the node 'a2:f6' was made to the node 'a3:0e'. 3) so far so good 4) the node 'a3:0e' was rebooted by issuing the 'reboot' command in the console 5) after this the connection is lost and the above logs were produced
I'm using the version 2011.4.0 on all nodes: [root@gtam00119 ~]# batctl -v batctl 2011.4.0 [batman-adv: 2011.4.0]
Any help is highly appreciated. I might be doing something wrong, but seems a stability problem.

Hello Marko,
thank you for reporting the issue and for the high quantity (and quality) of information you are giving us.

Starting from this point I would say that the problem is "before" the TT mechanism. batctl ping do not relies on the TTs as it directly use originator (node) addresses. Usually, in this cases, the problem is in the connection between nodes (most likely on the layer below).
And this is the output from 'batctl ll tt routes' from he node that is being pinged (see above):
[CUT]
From the log it is possible to see that the node is not receiving any TT_REPLY
message (which should solve the inconsistency being reported). This suggests us that the previous statement is probably true ("the problem is 'before" the TT mechanism").
Would you mind providing us the output of "batctl o" after the reboot on the node where you take the tt log? Moreover, could you please attach the output of "batctl td WIFI_IFACE" either on the unreachable node and on another one (maybe a2:f6?)
Cheers,

I was wondering whether you can directly provide us two .cap file (I think they are easier to inspect than looking at the batctl td output into an email :-))

Hi Antonio,
Its a bit difficult to provide you a cap file as this is a tightly embedded device (console only) and I would have to build wireshark for it. I'm copy/pasting the required information from the batctl output for both nodes.
If this doesn't help I will try to manage to get wireshark running, but it will be tricky.
Here you go:

Starting from this point I would say that the problem is "before" the TT mechanism. batctl ping do not relies on the TTs as it directly use originator (node) addresses. Usually, in this cases, the problem is in the connection between nodes (most likely on the layer below).
And this is the output from 'batctl ll tt routes' from he node that is being pinged (see above):
[CUT]
From the log it is possible to see that the node is not receiving any TT_REPLY
message (which should solve the inconsistency being reported). This suggests us that the previous statement is probably true ("the problem is 'before" the TT mechanism").
Would you mind providing us the output of "batctl o" after the reboot on the node where you take the tt log? Moreover, could you please attach the output of "batctl td WIFI_IFACE" either on the unreachable node and on another one (maybe a2:f6?)
Cheers,

Its a bit difficult to provide you a cap file as this is a tightly embedded device (console only) and I would have to build wireshark for it. I'm copy/pasting the required information from the batctl output for both nodes.
If this doesn't help I will try to manage to get wireshark running, but it will be tricky.
No need to build wireshark. tcpdump also is able to capture the packets and write them into a pcap file.

tcpdump would also work. I will read through the logs later (or maybe Antonio is faster).
Kind regards, Sven
I have to add that I had to modify the 'translation-table.c' file in order to build the version I'm using. I was facing unresolved symbols problems when loading the module due to the crc table. Thus, I added the crc table at the beginning of the file. However as sometimes the ping work I assumed this is not the root of the problem. Other than this no modifications were made to the sources.

Because you probably didn't add the crc16 module in the openwrt menuconfig (you are using openwrt right?)

Actually we think that your issue is not correlated to TT, therefore this change should not have nothing to do with the problem

Because you probably didn't add the crc16 module in the openwrt menuconfig (you are using openwrt right?)
No, I'm using a custom build kernel with Fedora 12 as the base.
Actually we think that your issue is not correlated to TT, therefore this change should not have nothing to do with the problem
Cheers,
I though it should be better to mention it to exclude any possible ghost-seeking.

The standard kernel also selects the crc16 module for you as soon as batman- adv is selected. Maybe you simply forgot to load the crc16 module ?

I have to add that I had to modify the 'translation-table.c' file in order to build the version I'm using. I was facing unresolved symbols problems when loading the module due to the crc table. Thus, I added the crc table at the beginning of the file. However as sometimes the ping work I assumed this is not the root of the problem. Other than this no modifications were made to the sources.
It looks like a problem of the wlan hardware/driver (just by scrolling over the log). The pinged node only receives broadcast messages but no unicast messages ("ICMP" is unicast in this situation and OGM broadcast). This is a first guess. So the node cannot request the changed table (thats why the inconsistency problem doesn't go away) and ping packets don't get replied.
Kind regards, Sven
