From dd72b0fedee1747698160cf3f839f332a4788059 Mon Sep 17 00:00:00 2001 From: Geliang Tang Date: Thu, 24 Sep 2020 08:29:59 +0800 Subject: selftests: mptcp: add remove addr and subflow test cases This patch added the remove addr and subflow test cases and two new functions. The first function run_remove_tests calls do_transfer with two new arguments, rm_nr_ns1 and rm_nr_ns2, for the numbers of addresses should be removed during the transfer process in namespace 1 and namespace 2. If both these two arguments are 0, we do the join test cases with "mptcp_connect -j" command. Otherwise, do the remove test cases with "mptcp_connect -r" command. The second function chk_rm_nr checks the RM_ADDR related mibs's counters. The output of the test cases looks like this: 11 remove single subflow syn[ ok ] - synack[ ok ] - ack[ ok ] rm [ ok ] - sf [ ok ] 12 remove multiple subflows syn[ ok ] - synack[ ok ] - ack[ ok ] rm [ ok ] - sf [ ok ] 13 remove single address syn[ ok ] - synack[ ok ] - ack[ ok ] add[ ok ] - echo [ ok ] rm [ ok ] - sf [ ok ] 14 remove subflow and signal syn[ ok ] - synack[ ok ] - ack[ ok ] add[ ok ] - echo [ ok ] rm [ ok ] - sf [ ok ] 15 remove subflows and signal syn[ ok ] - synack[ ok ] - ack[ ok ] add[ ok ] - echo [ ok ] rm [ ok ] - sf [ ok ] Suggested-by: Matthieu Baerts Suggested-by: Paolo Abeni Suggested-by: Mat Martineau Acked-by: Paolo Abeni Signed-off-by: Geliang Tang Reviewed-by: Mat Martineau Signed-off-by: David S.
