From 8dbdf24f4e9e060e4c4a3ad282a4a57f80f48b1f Mon Sep 17 00:00:00 2001 From: Matthieu Baerts Date: Wed, 25 Jan 2023 11:47:28 +0100 Subject: [PATCH] selftests: mptcp: userspace: avoid read errors During the cleanup phase, the server pids were killed with a SIGTERM directly, not using a SIGUSR1 first to quit safely. As a result, this test was often ending with two error messages: read: Connection reset by peer While at it, use a for-loop to terminate all the PIDs the same way. Also the different files are now removed after having killed the PIDs using them. It makes more sense to do that in this order.
