From 12a06a0bcf871467dcde4739efa6aaba351c60e0 Mon Sep 17 00:00:00 2001 From: Andrea Claudi Date: Thu, 27 Jul 2023 13:08:55 +0200 Subject: [PATCH] selftests: mptcp: join: fix 'implicit EP' test mptcp_join 'implicit EP' test currently fails when using ip mptcp: $ ./mptcp_join.sh -iI 001 implicit EP creation[fail] expected '10.0.2.2 10.0.2.2 id 1 implicit' found '10.0.2.2 id 1 rawflags 10 ' Error: too many addresses or duplicate one: -22. ID change is prevented[fail] expected '10.0.2.2 10.0.2.2 id 1 implicit' found '10.0.2.2 id 1 rawflags 10 ' modif is allowed[fail] expected '10.0.2.2 10.0.2.2 id 1 signal' found '10.0.2.2 id 1 signal ' This happens because of two reasons: - iproute v6.3.0 does not support the implicit flag, fixed with iproute2-next commit 3a2535a41854 ("mptcp: add support for implicit flag") - pm_nl_check_endpoint wrongly expects the ip address to be repeated two times in iproute output, and does not account for a final whitespace in it. This fixes the issue trimming the whitespace in the output string and removing the double address in the expected string.
