Subject: [PATCH mptcp-net v2 2/2] selftests: mptcp: userspace PM support for MP_PRIO signals
Date: Wed, 22 Jun 2022 20:59:48 -0400 [thread overview]
Message-ID: <20220623005948.291792-3-kishen.maloor@intel.com> (raw)
In-Reply-To: <20220623005948.291792-1-kishen.maloor@intel.com>
This change updates the testing sample (pm_nl_ctl) to take a
connection token as an optional param for the MPTCP_PM_CMD_SET_FLAGS
command. This is used to test the userspace PM code path for issuing
MP_PRIO signals over a connection for the specified address ID.
E.g. ./pm_nl_ctl set id 0 flags backup token 823274047
userspace_pm.sh has new selftests which exercise this command.
Fixes: 259a834fadda ("selftests: mptcp: functional tests for the userspace PM type")
Signed-off-by: Kishen Maloor <kishen.maloor@intel.com>
---
v2:
-added a sleep after issuing the MP_PRIO signal in userspace_pm.sh.
