This series of patches contains the changes for the redesigned bridge loop avoidance. The general concept is described in the wiki . I've already performed a few testcases  which worked fine in my kvm environment. No crashes while running or unloading the extension either.
This is the third version of the patchset, rebased on the master and including the changes according to reviews on the mailing list and personal discussions. Also a few things were fixed:
* turn blaII off by default - must be explicitly turned on * two rcu lock bugs (one found/fixed by Sven) * replace time_after with has_timed_out * fix the bla compile option * integrate patches and rebase on master (mostly done by Sven, thanks!) * fix alignment * fix psk_may_pull bug
Sven also roughly reviewed the code, so we hope its ready for integration now. ;)
The git repositories can be found on git.open-mesh.org: * blaII_dirty branch  has all the patches in development order * blaII branch  contains the patches squashed as sent the ml * blaII branch in batctl  contains the batctl changes
