selftests: mptcp: rm subflow with v4/v4mapped addr

2024-03-06T14:54:01Z

commit 7092dbee23282b6fcf1313fc64e2b92649ee16e8 upstream. 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.

selftests: mptcp: add mptcp_lib_is_v6

2024-03-06T14:54:01Z

commit b850f2c7dd85ecd14a333685c4ffd23f12665e94 upstream. 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.

selftests: mptcp: update userspace pm test helpers

2024-03-06T14:54:01Z

commit 757c828ce94905a2975873d5e90a376c701b2b90 upstream. 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.

selftests: mptcp: add chk_subflows_total helper

2024-03-06T14:54:01Z

commit 80775412882e273b8ef62124fae861cde8e6fb3d upstream. 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.

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.

commit 9480f388a2ef54fba911d9325372abd69a328601 upstream. Commands 'ss -M' are used in script mptcp_join.sh to display only MPTCP sockets. So it must be checked if ss tool supports MPTCP in this script.

selftests: mptcp: join: stop transfer when check is done (part 2)

2024-03-01T12:42:00Z

commit 04b57c9e096a9479fe0ad31e3956e336fa589cb2 upstream. Since the "Fixes" commits mentioned below, the newly added "userspace pm" subtests of mptcp_join selftests are launching the whole transfer in the background, do the required checks, then wait for the end of transfer. There is no need to wait longer, especially because the checks at the end of the transfer are ignored (which is fine). This saves quite a few seconds on slow environments. While at it, use 'mptcp_lib_kill_wait()' helper everywhere, instead of on a specific one with 'kill_tests_wait()'.
