From 42a667715b1e118f725de85ac748983ced2ecb5e Mon Sep 17 00:00:00 2001 From: "Jason A. Donenfeld" Date: Fri, 4 Jun 2021 17:17:35 +0200 Subject: [PATCH] wireguard: allowedips: initialize list head in selftest commit 46cfe8eee285cde465b420637507884551f5d7ca upstream. The randomized trie tests weren't initializing the dummy peer list head, resulting in a NULL pointer dereference when used. Fix this by initializing it in the randomized trie test, just like we do for the static unit test. While we're at it, all of the other strings like this have the word "self-test", so add it to the missing place here.
