David van Moolenbroek 0034abfa45 Always check whether netif_default is NULL ... In general, netif_default may be NULL, and various places in the code already check for this case before attempting to dereference the netif_default pointer. Some places do not perform this check though, and may cause null pointer dereferences if netif_default is not set. This patch adds NULL checks to those places as well.		2016-11-21 10:16:28 +01:00
