This is a note to let you know that I've just added the patch titled selftests: mptcp: pm nl: avoid error msg on older kernels to the 6.7-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: selftests-mptcp-pm-nl-avoid-error-msg-on-older-kernels.patch and it can be found in the queue-6.7 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. >From 662f084f3396d8a804d56cb53ac05c9e39902a7b Mon Sep 17 00:00:00 2001 From: "Matthieu Baerts (NGI0)" <matttbe@xxxxxxxxxx> Date: Thu, 15 Feb 2024 19:25:35 +0100 Subject: selftests: mptcp: pm nl: avoid error msg on older kernels From: Matthieu Baerts (NGI0) <matttbe@xxxxxxxxxx> commit 662f084f3396d8a804d56cb53ac05c9e39902a7b upstream. Since the 'Fixes' commit mentioned below, and if the kernel being tested doesn't support the 'fullmesh' flag, this error will be printed: netlink error -22 (Invalid argument) ./pm_nl_ctl: bailing out due to netlink error[s] But that can be normal if the kernel doesn't support the feature, no need to print this worrying error message while everything else looks OK. So we can mute stderr. Failures will still be detected if any.
