From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: "Jason A. Donenfeld" Date: Tue, 4 Feb 2020 22:17:29 +0100 Subject: [PATCH] wireguard: selftests: tie socket waiting to target pid commit 88f404a9b1d75388225b1c67b6dd327cb2182777 upstream. Without this, we wind up proceeding too early sometimes when the previous process has just used the same listening port. So, we tie the listening socket query to the specific pid we're interested in.
