From 2e1a569b77f656500317cf2ca2382e9222ceab2f Mon Sep 17 00:00:00 2001 From: Philippe De Swert Date: Sun, 8 Feb 2015 22:21:51 +0200 Subject: libsystemd-network: Avoid potential NULL dereference in test-lldp As a malloc0 could fail, doing a strncpy without checking could cause issues. Adding an assert should be good enough and in line with other similar routines in the code.
