The following commit has been merged in the master branch: commit a5256f7e74d85d7ae60ac3bd557d5fe3444be810 Author: Antonio Quartulli <antonio(a)meshcoding.com> Date: Tue Aug 4 22:26:19 2015 +0200 batman-adv: don't access unregistered net_device object In batadv_hardif_disable_interface() there is a call to batadv_softif_destroy_sysfs() which in turns invokes unregister_netdevice() on the soft_iface. After this point we cannot rely on the soft_iface object anymore because it might get free'd by the netdev periodic routine at any time. For this reason the netdev_upper_dev_unlink(.., soft_iface) call is moved before the invocation of batadv_softif_destroy_sysfs() so that we can be sure that the soft_iface object is still valid.
