[PATCH net-next 11/11] selftests: mptcp: listener test for in-kernel PM
From: Matthieu Baerts
Date: Wed Nov 30 2022 - 09:09:11 EST
From: Geliang Tang <geliang.tang@xxxxxxxx>
This patch adds test coverage for listening sockets created by the
in-kernel path manager in mptcp_join.sh.
It adds the listener event checking in the existing "remove single
address with port" test. The output looks like this:
003 remove single address with port syn[ ok ] - synack[ ok ] - ack[ ok ]
add[ ok ] - echo [ ok ] - pt [ ok ]
syn[ ok ] - synack[ ok ] - ack[ ok ]
syn[ ok ] - ack [ ok ]
rm [ ok ] - rmsf [ ok ] invert
CREATE_LISTENER 10.0.2.1:10100[ ok ]
CLOSE_LISTENER 10.0.2.1:10100 [ ok ]
