The following commit has been merged in the master branch: commit e2790a4b275d52e332e0ad71b5f2eff53fe21805 Author: Sven Eckelmann <sven(a)narfation.org> Date: Sat Apr 1 14:47:05 2017 +0200 batman-adv: Remove ethtool .get_settings stub The .get_settings function pointer and the related API was deprecated. Fortunately, batman-adv is a virtual interface and never provided any useful information via .get_settings. The stub can therefore be removed. This also avoids that incorrect information is shown in ethtool about the batadv interface.

The following commit has been merged in the master branch: commit a3a5129e122709306cfa6409781716c2933df99b Author: Andreas Pape <APape(a)phoenixcontact.com> Date: Mon Sep 5 13:20:29 2016 +0200 batman-adv: handle race condition for claims between gateways Consider the following situation which has been found in a test setup: Gateway B has claimed client C and gateway A has the same backbone network as B. C sends a broad- or multicast to B and directly after this packet decides to send another packet to A due to a better TQ value. B will forward the broad-/multicast into the backbone as it is the responsible gw and after that A will claim C as it has been chosen by C as the best gateway. If it now happens that A claims C before it has received the broad-/multicast forwarded by B (due to backbone topology or due to some delay in B when forwarding the packet) we get a critical situation: in the current code A will immediately unclaim C when receiving the multicast due to the roaming client scenario although the position of C has not changed in the mesh. If this happens the multi-/broadcast forwarded by B will be sent back into the mesh by A and we have looping packets until one of the gateways claims C again. In order to prevent this, unclaiming of a client due to the roaming client scenario is only done after a certain time is expired after the last claim of the client. 100 ms are used here, which should be slow enough for big backbones and slow gateways but fast enough not to break the roaming client use case.
