From e255683c06df572ead96db5efb5d21be30c0efaa Mon Sep 17 00:00:00 2001 From: "Matthieu Baerts (NGI0)" matttbe@kernel.org Date: Mon, 19 Aug 2024 21:45:19 +0200 Subject: [PATCH] mptcp: pm: re-using ID of unused removed ADD_ADDR
If no subflow is attached to the 'signal' endpoint that is being removed, the addr ID will not be marked as available again.
Mark the linked ID as available when removing the address entry from the list to cover this case.
Fixes: b6c08380860b ("mptcp: remove addr and subflow in PM netlink")
For the same reasons as the ones invoked for v5.15, I don't think we need to backport this patch to v5.10.
Cheers, Matt
