+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.
+
+Fixes: e7096c131e51 ("net: WireGuard secure network tunnel")
