From stable+bounces-172418-greg=3Dkroah.com@vger.kernel.org Fri Aug 22 16:1= 7:38 2025 From: "Matthieu Baerts (NGI0)" Date: Fri, 22 Aug 2025 16:11:28 +0200 Subject: selftests: mptcp: pm: check flush doesn't reset limits To: mptcp@lists.linux.dev, stable@vger.kernel.org, gregkh@linuxfoundation.o= rg Cc: "Matthieu Baerts (NGI0)" , sashal@kernel.org, Mat M= artineau , Jakub Kicinski Message-ID: <20250822141124.49727-8-matttbe@kernel.org> From: "Matthieu Baerts (NGI0)" commit 452690be7de2f91cc0de68cb9e95252875b33503 upstream. This modification is linked to the parent commit where the received ADD_ADDR limit was accidentally reset when the endpoints were flushed. To validate that, the test is now flushing endpoints after having set new limits, and before checking them. The 'Fixes' tag here below is the same as the one from the previous commit: this patch here is not fixing anything wrong in the selftests, but it validates the previous fix for an issue introduced by this commit ID.
