- Status changed from New to In Progress
Just to confirm: You don't activate the module by adding interfaces ? You just load it (modprobe batman-adv) which makes it crash ?

The loading with "insmod batman-adv.ko".

The function receive_raw_packet() which you can find in the tracelog you provided can't be called without an active interface. That leads to the conclusion you configured batman-adv somehow. We need to know what you configured in order to reproduce the issue. Also, the function proc_interfaces_write() that is mentioned as well gets called when you try to set an interface. I guess something is special about the interface you are trying to activate. If you are not aware of any options may be you have a start script somewhere ?

Sorry for the late response.
You are right the driver for that device is "non-standard". I'm working with batman-adv on Freerunner GTA02 devices. They use a ar6000 chipset which is not supported by the linux-wireless group, because it is a full-mac hardware.
I configure the batman device with a ipv4 address and a ipv6 local-link address. Nothing else, if that is what you mean.

Hmm.., I have to reproduce that otherwise it gets hard. I can dig out my Freerunner but I need the image you are using. Where can I get it ? And then I need the exact steps which lead to the crash.
Updated by Anonymous over 14 years ago
You need the kernel i use, right? The other userspace related stuff shouldn't have anything to do with it.
I'm using a recent version of the "andy-branch" from the openmoko kernel. You can build one for yourself (https://wiki.openmoko.org/wiki/Kernel#Building_the_andy-tracking_branch).
If you need more than that, please contact me.

It is very difficult to help you if you don't let us know what exactly you are doing. You might have found a bug which we need to reproduce first at our end in order to fix it. With the information you supplied that is not possible.
Please provide the kernel image & rootfs you are using plus any startup scripts / commands / setup descriptions related to batman.

Ok, i was a bit shy to submit this, because i use a hackable1 image, which is pretty big (a debian based distribution).
I uploaded the rootfs (including the kernel) to https://www-user.tu-chemnitz.de/~kait/gta02-image.tar.gz
Please leave me a message when you got it, so i can delete it.
The startup script i use is /etc/init.d/batman. The bootmanager I use is Qi, so the kernel that gets booted, is the one that /boot/uImage-GTA02.bin points to.

Ok, I got it. Thanks for your help.
Would you mind joining our IRC channel or continue this via email ? The latency might improve. ;-)
Updated by Marek Lindner over 14 years ago
Not sure how to reach you, so I try it here again.
I have fixed various startup problems. Could you please try it again using the latest version (at least rev 1409) and let me know about the result?

Now it is not crashing direct after loading any more. But I get the following errors when doing after activating a interface with:

Replying to [comment:12 kait]:
Now it is not crashing direct after loading any more.
That is good news! :-)
But I get the following errors when doing after activating a interface with:
$echo "eth1" > /proc/net/batman-adv/interfaces
Wow - the freerunner seems to trigger every (almost) impossible race condition that no-one saw before. ;-)
I see the problem but I have to think about a solution ..
Updated by Marek Lindner over 14 years ago
Ok, r1425 should fix this issue.
Keep us posted. :-)
Updated by Anonymous over 14 years ago
Ok, looks like you fixed this one :) I tested it with r1426.
Now the nodes don't crash anymore. But (there always is a "but", isn't it?) they don't build a mesh. The nodes are sending their originator messages, but the other nodes don't receive them. At least it looks like that, from my point of view.
I have no idea what more information i could give you. The logfiles are all looking normal, no error messages at all.
Updated by Marek Lindner over 14 years ago
Yes, this was a regression that came with r1425. We fixed it in r1427.
Updated by Anonymous over 14 years ago
Tested with r1427 today.
I get these errors when setting the ip address

Updated by Marek Lindner over 14 years ago
It is a bit confusing because the error log you pasted seems unrelated to the IP address. In the log message you can see proc_interfaces_write() which gets called if you add an interface to /proc/.../interfaces. Are you sure it is related to the IP address ?
Using your startscript does not provoke a crash here but you might run into a race condition that I don't trigger. You are running this on top of 2.6.28 or 2.6.31 ?
Updated by Anonymous over 14 years ago
You are right. The module crashes when adding the interface. Sorry, i got that wrong.
The Kernel:
$ uname -a $ Linux runner2 2.6.29-GTA02_andy-tracking-mokodev #5 PREEMPT Fri Aug 28 11:50:30 CEST 2009 armv4tl GNU/Linux

I made a patch for that bug (r1432), please check it.
Are you running the kernel with debugging enabled ? If so, I'd like to know what options you have. I started the module a dozen times but I'm not able to trigger this. :-)
Updated by Anonymous over 14 years ago
Looks line r1432 is working. At least it doesn't crash anymore.
I don't know if this has anything to do with batman at all, but I have problems when trying to ping other nodes via the bat0 device.
# ping6 fe80::2ff:fff:fed2:cc99%bat0 ping: getnameinfo: Temporary failure in name resolution 64 bytes from unknown: icmp_seq=0 ttl=64 time=44.101 ms # ping6 2001:bd8:4711::102 PING 2001:bd8:4711::102 (2001:bd8:4711::102): 56 data bytes ping: getnameinfo: Temporary failure in name resolution 64 bytes from unknown: icmp_seq=0 ttl=64 time=1.186 ms # ping6 fe80::212:cfff:fe8f:587%eth1 PING fe80::212:cfff:fe8f:587%eth1 (fe80::212:cfff:fe8f:587%eth1): 56 data bytes 64 bytes from runner1: icmp_seq=0 ttl=64 time=25.354 ms 64 bytes from runner1: icmp_seq=1 ttl=64 time=10.596 ms 64 bytes from runner1: icmp_seq=2 ttl=64 time=12.319 ms [...]
I use ipv6 addresses and this problem exists over the global scope and the link local scope address, but only when using the bat0 device. When I use the wireless device directly, I have no problems. Thats the reason why I think, that maybe it is a problem with batman.
I attached the kernel config file.
Updated by Linus Lüssing over 14 years ago
Hi kait. I'm having my doubts that this might be batman-related too. Well, it should be normal that you're not able to do any recursive link-local address lookups as they are only unique for the certain link, right?
But I'm also wondering, where you got this runner1 from, did you make any entries in your /etc/hosts for that?
My output with batman or without looks just like this with a current batman-svn-version and the default debian 2.6.30-kernel from unstable:
ping6 fe80::2ff:74ff:fe52:fbfa%bat0 PING fe80::2ff:74ff:fe52:fbfa%bat0(fe80::2ff:74ff:fe52:fbfa) 56 data bytes 64 bytes from fe80::2ff:74ff:fe52:fbfa: icmp_seq=1 ttl=64 time=0.057 ms 64 bytes from fe80::2ff:74ff:fe52:fbfa: icmp_seq=2 ttl=64 time=0.084 ms
Hmm, maybe a 'ping6 -n' could be a workaround for the moment ;)?

Can we close this ticket assuming there are no further problems ?
