batman-adv crash when removing interface in certain configurations #680
Description
When I configure more then 2 VLANs via UCI for mesh-connections and add them to bat0 the network stack isn't working correctly any longer. Any invocation of ip, ifconfig, brctl, batctl etc will result in a stuck system.
If I configure just two mesh-VLANs the system is working fine. It is also possible to add more VLANs to bat0 via "vconfig eth0.x" and "batctl if add eth0.x".
The strange part is before the crash happens the kernel always prints "tried to remove device eth0 from br-client" but eth0 itself shouldn't be part of any bridge or whatever. I also don't see this message when I configure just two mesh-VLANs.
See attached files for backtrace and /etc/config/network.
If you need further information please let me know.
EDIT:
- Tested with v2016.1.1 and master.
- Problem occurs on two pieces of hardware.
