From 865a6cbb2288f8af7f9dc3b153c61b7014fdcf1e Mon Sep 17 00:00:00 2001 From: tannerlove Date: Tue, 9 Jun 2020 17:21:32 -0400 Subject: [PATCH] selftests/net: in rxtimestamp getopt_long needs terminating null entry getopt_long requires the last element to be filled with zeros. Otherwise, passing an unrecognized option can cause a segfault.
