From b5cbffeea885ff374246aa0d56cbb4709087f80c Mon Sep 17 00:00:00 2001 From: "Jason A. Donenfeld" Date: Wed, 21 Apr 2021 17:03:25 -0600 Subject: [PATCH] allowedips: initialize list head in selftest 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. Signed-off-by: Jason A.
