+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.
