[PATCH 6.7 157/162] selftests: mptcp: add evts_get_info helper

Greg Kroah-Hartman
2024-03-04T21:32:41Z

From: Geliang Tang <geliang.tang@suse.com>

commit 06848c0f341ee3f9226ed01e519c72e4d2b6f001 upstream.

This patch adds a new helper get_info_value(), using 'sed' command to
parse the value of the given item name in the line with the given keyword,
to make chk_mptcp_info() and pedit_action_pkts() more readable.

Also add another helper evts_get_info() to use get_info_value() to parse
the output of 'pm_nl_ctl events' command, to make all the userspace pm
selftests more readable, both in mptcp_join.sh and userspace_pm.sh.
