From 372fa0f3f867eee4b949727aa5c2e4fa9e728d55 Mon Sep 17 00:00:00 2001 From: Hans Dedecker Date: Thu, 24 Apr 2014 07:51:15 +0000 Subject: [PATCH] netifd: Mark interface as dynamic after it has been added in the interface list Adding an interface in the interface list in case of a config update will override the node version of the old interface and thus overriding the dynamic interface marker. In case of config update interface_set_dynamic is done on an invalid interface pointer as the new interface pointer has been freed.
