# flush and re-add
This test extends "delete re-add signal" to validate the previous commit: when the 'signal' endpoint linked to the initial subflow (ID 0) is re-added multiple times, it will re-send the ADD_ADDR with id 0. The client should still be able to re-create this subflow, even if the add_addr_accepted limit has been reached as this special address is not considered as a new address. 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. Fixes: d0876b2284cf ("mptcp: add the incoming RM_ADDR support") Cc: stable@vger.kernel.org Reviewed-by: Mat Martineau <martineau@kernel.org> Signed-off-by: Matthieu Baerts (NGI0) <matttbe@kernel.org> --- v2: - Make the connection longer, to have time to finish all the endpoints manipulations when executed in slow environments. At the end of the operations, the connection is killed, so it doesn't make the test longer.
