Hi,
I want to test the Bridge loop avoidance II with our OpenWrt Freifunk
firmware. Is there a version that works and can be tested? Which git repo do I
have to use and what are the main steps to compile it into openwrt?
Regards
Clemens

Simon Wunderlich is the maintainer of the bridge loop avoidance II patchset.
His current version can be found in his repo [1] in branch blaII (or another
branch with blaII in the name). It is currently not rebased on top of master
or v2011.4.0... so you cannot take the patchset and put it in OpenWRT.
A quick and easy way would be to clone the repo, make a diff using
`git diff v2011.4.0..origin/blaII > blaII.patch` and place the resulting patch
in the patches directory [2]. Keep in mind that this patch removes some
changes that were added before the release of 2011.4.0 and adds some other
ones which were already applied in master. His next-blaII branch is also a
little bit newer (includes some fixes for smaller problems) and could be a
better starting point.
You can find the patches merged after the release of v2011.4.0 and not part of
the blaII patchset using:
git log --no-merges '^v2011.4.0' 8dd0e9973429c80f52483e8045862f61a74b6fd6
I am sorry that I cannot give a perfect answer right now.
Kind regards,
Sven

Sry for this questions but I´m absolutely not very familar with this things so
I need your help to test it.

Ok I created a patch from this version now and put it into the patches folder.
This worked. So forget about the last mail.
What´s about the make option to enable bla2? How does this need to be applied
to the makefile in openwrt or is there no need to change anything because the
option in in batman advanced own makefile is set to y?

Sry for the delay, but we were busy rebasing and fixing the blaII code. There
are also some other meetings we are currently attending.
But to make it short: The code is automatically built (you correctly saw the
CONFIG_BATMAN_ADV_BLA=y), but you have to enable it through the new sysfs file
"bridge_loop_avoidance" or the batctl option.
Kind regards,

We used the rebased version and got the module compiled (yeah! ;).
I enabled blaII on one node, and after that all nodes connected to the vpn
went unreachable. Most of them use 2011.0.0, some others 2011.4.0, running an
ad-hoc iface as bat-adv-iface and bat0, tap0 and ath0(master, for clients) as
a bridge. Do the blaII-packets "kill" all the other nodes? I thought the
blaII-packets would have no effect on the other nodes because of the compat-

You should use the same version everywhere. The compat layer is only to get a
version running on an older kernel... not for incompatibilities between the
different features/versions of batman-adv.
Marek already suggested that the packet format version should be increased to
clearly state that these versions are not compatible. But it could also be
that you triggered a bug in the new bla implementation... still I don't
understand why you are doing this. Which node should detect the ARP packets?
Maybe you can explain it again to better understand your network architecture.
Thanks,
Sven

Before you update all your nodes to the same version it would be really
helpful to find out if there is an incompatibility between the old BLA and the
new BLA. We are not 100% sure about that.
By the way, looking at our compatibility number table (http://www.open-
mesh.org/wiki/batman-adv/Compatversion) I see that 2011.0.0 has compat 12
whereas 2011.4.0 has compat number 14. That could be the reason why your setup
is not working.
Cheers,
Marek
