From 7092dbee23282b6fcf1313fc64e2b92649ee16e8 Mon Sep 17 00:00:00 2001 From: Geliang Tang tanggeliang@kylinos.cn Date: Fri, 23 Feb 2024 17:14:12 +0100 Subject: [PATCH] selftests: mptcp: rm subflow with v4/v4mapped addr
Now both a v4 address and a v4-mapped address are supported when destroying a userspace pm subflow, this patch adds a second subflow to "userspace pm add & remove address" test, and two subflows could be removed two different ways, one with the v4mapped and one with v4.

Hi Greg,
To be able to apply the last patch without conflicts in v6.6, 4 other clean-up patches are needed.
These patches mainly replace existing code with helpers to reduce code duplication. It looks interesting to backport them to ease future backports.
I had a few conflicts in mptcp_lib.sh, because some of the new helpers have been backported recently, but not all: so I had to place them between others.
Note that these patches are the same the ones I sent earlier for v6.7, no other conflicts.

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.

This patch adds a new helper chk_subflows_total(), in it use the newly added counter mptcpi_subflows_total to get the "correct" amount of subflows, including the initial one.
To be compatible with old 'ss' or kernel versions not supporting this counter, get the total subflows by listing TCP connections that are MPTCP subflows:
ss -ti state state established state syn-sent state syn-recv | grep -c tcp-ulp-mptcp.

From: Geliang Tang geliang.tang@suse.com
This patch adds a new argument namespace to userspace_pm_add_addr() and userspace_pm_add_sf() to make these two helper more versatile.
Add two more versatile helpers for userspace pm remove subflow or address: userspace_pm_rm_addr() and userspace_pm_rm_sf(). The original test helpers userspace_pm_rm_sf_addr_ns1() and userspace_pm_rm_sf_addr_ns2() can be replaced by these new helpers.

From: Geliang Tang geliang.tang@suse.com
To avoid duplicated code in different MPTCP selftests, we can add and use helpers defined in mptcp_lib.sh.
is_v6() helper is defined in mptcp_connect.sh, mptcp_join.sh and mptcp_sockopt.sh, so export it into mptcp_lib.sh and rename it as mptcp_lib_is_v6(). Use this new helper in all scripts.

Now both a v4 address and a v4-mapped address are supported when destroying a userspace pm subflow, this patch adds a second subflow to "userspace pm add & remove address" test, and two subflows could be removed two different ways, one with the v4mapped and one with v4.
