If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. >From stable-owner@xxxxxxxxxxxxxxx Thu Jun 22 12:39:32 2023 From: Matthieu Baerts <matthieu.baerts@xxxxxxxxxxxx> Date: Thu, 22 Jun 2023 12:39:14 +0200 Subject: selftests: mptcp: join: skip userspace PM tests if not supported To: stable@xxxxxxxxxxxxxxx, gregkh@xxxxxxxxxxxxxxxxxxx Cc: Matthieu Baerts <matthieu.baerts@xxxxxxxxxxxx>, Jakub Kicinski <kuba@xxxxxxxxxx> Message-ID: <20230622103914.2951296-1-matthieu.baerts@xxxxxxxxxxxx> From: Matthieu Baerts <matthieu.baerts@xxxxxxxxxxxx> commit f2b492b04a167261e1c38eb76f78fb4294473a49 upstream. Selftests are supposed to run on any kernels, including the old ones not supporting all MPTCP features. One of them is the support of the userspace PM introduced by commit 4638de5aefe5 ("mptcp: handle local addrs announced by userspace PMs") and the following ones. It is possible to look for the MPTCP pm_type's sysctl knob to know in advance if the userspace PM is available.
