Hope it helps.... The part Marek quoted at least did change :)

The biggest problem is, that it is relative unreadable due to the reformatting done by your mua. The next big problem is that the guessing will begin now using the information in the stacktrace.
My first guess would be hardif_min_mtu. Maybe the netdev we want to access was removed in the time we try to update our information of the removed/deactivated interface (or another interface we also received some kind of notification).
I would have guessed that this cannot happen because we haven't processed all notification items, but I am awake a little bit too long to make 100% correct statements.
Maybe because we use dev_put in hardif_deactivate_interface too early and iterate over the already 'putted' device in our list (will be removed in hardif_remove_interface from our list) - which seems to be wrong too me right now. So all references will be gone when the interface goes down (so maybe it will be completely deleted at that point), but the pointer to the destroyed netdev is still in our list and will only deleted when the device will really be unregistered.
thanks, Sven
Hi, batman community members.
I also met problem similar to Tim's case. My environment is, board: gateworks avila gw2348-4 wlan module: wistron dcma-82(ar5414) firmware: openwrt trunk r22692 wlan driver: ath5k batman version: batman-adv-devel (refered to http://www.open-mesh.org/wiki/building-batman-adv-with-openwrt) (for trial of multi interface altering)
I built firmware image with symbol table option. Is it helpful?
regards, Kazuki

I built firmware image with symbol table option. Is it helpful?

As far as I understand the current trunk should not exhibit this behaviour which gives me the impression that you are not running the latest version. You downloaded the devel package but did you also adjust the Makefile's SVN revision to your liking ?
Regards, Marek
With all this discussion on the technical details of the protocols, I don't see discussion of working or almost-working systems. Clearly, there are working systems, with perhaps a few constraints, such as those of the U.S. military. But if someone wanted to buy the components to set up a system that would work reasonably well most of the time, to whom should she be referred?

No, it is not wrong but you might want to change the PKG_REV field to match with the SVN revision you want to use. If you are interested in the latest trunk you should set it to 1776. We don't update this number each time something gets committed.
Cheers, Marek
Hi, Marek and Sven.
I'm sorry to be late to reply. Thank you for your instruction and patches. I could update to latest revision 1778 and built successfully.

Hm, thats not much information. So here some question to enrich it a little bit (otherwise I have no idea were the problem might be as I could not reproduce it yet).
How did you connect? Using serial console or using lan (from output I would guess serial console).
Does the hang always happen?
Can you reproduce the problem with the version in linux-2.6.36-rc3 or maint/next of the batman-adv git repository? Can you reproduce the problem by doing the necessary insmode/iw/batctl/rmmod steps by hand (aka no configuration using /etc, but manually)? What where your calls? Which call made it hang? Can you drop parts of you iw/batctl calls and the hang still occurs?
Can you add printks in hard-interface.c around the call of hardif_remove_interface inside hard_if_event to check if it stops inside that function and if it does then please try to add more printks inside of hardif_remove_interface and hardif_disable_interface.
thanks, Sven

Yes.

I added printk() in hard-interface.c and soft-interface.c. This is it.

"exit softif_destroy\n" is not printed out. unregister_netdev?
Thanks in advance.

Thanks, perfect work. This is a new bug which was added in the multiple mesh patchset. The problem is that the rtnl lock is taken and we still use unregister_netdev when we process an event using hard_if_event.
I have to check other code paths to ensure that I don't destroy other things, but a workaround for you would be to use unregister_netdevice instead of unregister_netdev in that situation. (Just check v0.2.1-30-g992bfd1 for more information on that subject).
The problem is that softif_destroy is also called when we unloading the module - which means that it assumes that the rtnl lock is taken (which it is not when you don't use unregister_netdev there). So I will work on a complete fix and Cc it to you.
Thanks, Sven
Hi, Sven.
Thank you for your patch and sorry to be late to reply.
I updated the revision to r1780. The problem is gone.
After network restart, wlan interfaces under bat0 are still deactivated. But it's not big problem. "/etc/init.d/batman-adv restart" makes them activated.
Thanks a lot,
Kazuki Shimada
P.S. When activating network interfaces under bat0, What about forcing their mtu value to 1527?

Why? Everybody should be able to use it in a environment where he can decide how the mtu looks like. If he thinks that the mtu should be 1337 or 2342 then it is fine for us. He can even (he should not, but he can) use that mtu in a environment where the mtu of the underlying hardware is only 1300 (for example a switch or other hardware only allows that) - thanks goes to Andreas' fragmentation patch for that. There are some restrictions, but as said on different posts: get your mtus right and everything will be fine. :)
So we do it the net/bridge/ way and just accept every mtu and use the minimal mtu of all devices (that's why some patches from me were rejected). It would also be a little bit confusing if a interface used by batman-adv would be change its mtu and silently dropped - or more evil when we try to change the mtu of the used device and the underlying hardware would not support that mtu and everything would start to break.
Best regards, Sven

By removing interfaces entirely, i.e. network restart, batman purges the settings it had regarding these interfaces.

As Sven pointed out: There might be interfaces which do not allow to increase the MTU or situations in which that is not desirable.
Note that OpenWRT allows to specify the MTU in the configuration files (/etc/config/network), so that you don't need to manually configure it each time you invoke "network restart".

Ah, OK.

Oh, thank you for your advice. I'll try it.

Yes, it did.
Could you please copy the attached patch into your batman-advanced patches folder and verify whether it fixes your problem ? This document explains the location of that folder and how to rebuild the package: http://www.open-mesh.org/wiki/building-batman-adv-with-openwrt

Here is the updated notify patch plus another patch which might solve the issue. These are the patches posted by Sven but backported to 2000.0.0 and prepared for OpenWRT. Please try the notify patch first and if it does not work add the dev_hold patch and let us know how it goes.
