From 27915aa61060fd8954a68a86657784705955088a Mon Sep 17 00:00:00 2001 From: Sven Eckelmann Date: Wed, 2 Nov 2016 18:14:43 +0100 Subject: batman-adv: Revert "fix splat on disabling an interface" MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The commit 9799c50372b2 ("batman-adv: fix splat on disabling an interface") fixed a warning but at the same time broke the rtnl function add_slave for devices which were temporarily removed. batadv_softif_slave_add requires soft_iface of and hard_iface to be NULL before it is allowed to be enslaved. But this resetting of soft_iface to NULL in batadv_hardif_disable_interface was removed with the aforementioned commit.

It stops the test after these and reports it to userspace. This also has to be done when the primary interface disappeared during the test.
