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")
