Repository : ssh://git@open-mesh.org/batman-adv On branch : maint >--------------------------------------------------------------- commit 2808f92a9e3e3a920ac2c40710a0fedf9f7a4525 Author: Andrew Lunn <andrew(a)lunn.ch> Date: Thu Feb 11 22:15:57 2016 +0100 batman-adv: Avoid endless loop in bat-on-bat netdevice check batman-adv checks in different situation if a new device is already on top of a different batman-adv device. This is done by getting the iflink of a device and all its parent. It assumes that this iflink is always a parent device in an acyclic graph. But this assumption is broken by devices like veth which are actually a pair of two devices linked to each other. The recursive check would therefore get veth0 when calling dev_get_iflink on veth1. And it gets veth0 when calling dev_get_iflink with veth1. Creating a veth pair and loading batman-adv freezes parts of the system ip link add veth0 type veth peer name veth1 modprobe batman-adv An RCU stall will be detected on the system which cannot be fixed.
