2025-05-27selftests: net: move wait_local_port_listen to lib.shHangbin Liu
The function wait_local_port_listen() is the only function defined in net_helper.sh. Since some tests source both lib.sh and net_helper.sh, we can simplify the setup by moving wait_local_port_listen() to lib.sh. With this change, net_helper.sh becomes redundant and can be removed.

2025-05-05selftests: mptcp: add helpers to get subflow_infoGang Yan
This patch adds 'get_subflow_info' in 'mptcp_diag', which can check whether a TCP connection is an MPTCP subflow based on the "INET_ULP_INFO_MPTCP" with tcp_diag method. The helper 'print_subflow_info' in 'mptcp_diag' can print the subflow_filed of an MPTCP subflow for further checking the 'subflow_info' through inet_diag method. The example of the whole output should be: $ ./mptcp_diag -s "127.0.0.1:10000 127.0.0.1:38984" 127.0.0.1:10000 -> 127.0.0.1:38984 It's a mptcp subflow, the subflow info: flags:Mec token:0000(id:0)/4278e77e(id:0) seq:9288466187236176036 \ sfseq:1 ssnoff:2317083055 maplen:215 Co-developed-by: Geliang Tang <geliang@kernel.org> Signed-off-by: Geliang Tang <geliang@kernel.org> Signed-off-by: Gang Yan <yangang@kylinos.cn> Reviewed-by: Matthieu Baerts (NGI0) <matttbe@kernel.org> Signed-off-by: Matthieu Baerts (NGI0) <matttbe@kernel.org> Link: https://patch.msgid.link/20250502-net-next-mptcp-sft-inc-cover-v1-6-68eec95898fb@kernel.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2025-05-05selftests: mptcp: refactor NLMSG handling with 'proto'Gang Yan
This patch introduces the '__u32 proto' variable to the 'send_query' and 'recv_nlmsg' functions for further extending function. In the 'send_query' function, the inclusion of this variable makes the structure clearer and more readable. In the 'recv_nlmsg' function, the '__u32 proto' variable ensures that the 'diag_info' field remains unmodified when processing IPPROTO_TCP data, thereby preventing unintended transformation into 'mptcp_info' format. While at it, increment iovlen directly when an item is added to simplify this portion of the code and improve its readaility.

2025-05-05selftests: mptcp: info: hide 'grep: write error' warningsMatthieu Baerts (NGI0)
mptcp_lib_get_info_value() will only print the first entry that match the filter because of the ';q' at the end. As a consequence, the 'sed' command could finish before the previous 'grep' one and print a 'write error' warning because it is trying to write data to the closed pipe. Such warnings are not interesting, they can be hidden by muting stderr here for grep.

2025-04-23selftests: mptcp: diag: use mptcp_lib_get_info_valueGeliang Tang
When running diag.sh in a loop, chk_dump_one will report the following "grep: write error": 13 ....chk 2 cestab [ OK ] grep: write error 14 ....chk dump_one [ OK ] 15 ....chk 2->0 msk in use after flush [ OK ] 16 ....chk 2->0 cestab after flush [ OK ] This error is caused by a broken pipe. When the output of 'ss' is processed by grep, 'head -n 1' will exit immediately after getting the first line, causing the subsequent pipe to close. At this time, if 'grep' is still trying to write data to the closed pipe, it will trigger a SIGPIPE signal, causing a write error. One solution is not to use this problematic "head -n 1" command, but to use mptcp_lib_get_info_value() helper defined in mptcp_lib.sh to get the value of 'token'.

Most of the time, it is then kept at 0, except when the PM limits cause the receiver side to reject new MPJoin connections.

2025-02-05selftests: mptcp: connect: -f: no reconnectMatthieu Baerts (NGI0)
The '-f' parameter is there to force the kernel to emit MPTCP FASTCLOSE by closing the connection with unread bytes in the receive queue. The xdisconnect() helper was used to stop the connection, but it does more than that: it will shut it down, then wait before reconnecting to the same address. This causes the mptcp_join's "fastclose test" to fail all the time. This failure is due to a recent change, with commit 218cc166321f ("selftests: mptcp: avoid spurious errors on disconnect"), but that went unnoticed because the test is currently ignored.

In order to unify what is printed in case of error, similar to what is done in mptcp_connect.sh and mptcp_join.sh, it is interesting to do the following modifications in simult_flows.sh: - Print the rc errors at the end of the line. - Print the MIB counters. - Use the same ss options: add -M (MPTCP sockets) and -e (detailed socket information). While at it, also print of the 'max' time only in case of success, because 'mptcp_connect.c' will already print this info in case of error, e.g.: transfer slower than expected! runtime 11948 ms, expected 11921 ms Reviewed-by: Geliang Tang <geliang@kernel.org> Signed-off-by: Matthieu Baerts (NGI0) <matttbe@kernel.org> Link: https://patch.msgid.link/20250114-net-next-mptcp-st-more-debug-err-v1-1-2ffb16a6cf35@kernel.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>

Recently, the net/lib.sh file has been modified to include defer.sh from net/lib/sh/ directory. The Makefile from net/lib has been modified accordingly, but not the ones from the sub-targets using net/lib.sh. Because of that, the new file is not installed as expected when installing the Forwarding, MPTCP, and Netfilter targets, e.g. # make -C tools/testing/selftests TARGETS=net/mptcp install \ INSTALL_PATH=/tmp/kself # cd /tmp/kself/ # ./run_kselftest.sh -c net/mptcp TAP version 13 1..7 # timeout set to 1800 # selftests: net/mptcp: mptcp_connect.sh # ./../lib.sh: line 5: /tmp/kself/net/lib/sh/defer.sh: No such file or directory # (...)

Explicitly verify that MPC connection attempts towards a port-based signal endpoint fail with a reset. Note that this new test is a bit different from the other ones, not using 'run_tests'. It is then needed to add the capture capability, and the picking the right port which have been extracted into three new helpers. The info about the capture can also be printed from a single point, which simplifies the exit paths in do_transfer().

2024-09-11selftests: mptcp: join: restrict fullmesh endp on 1st sfMatthieu Baerts (NGI0)
A new endpoint using the IP of the initial subflow has been recently added to increase the code coverage. But it breaks the test when using old kernels not having commit 86e39e04482b ("mptcp: keep track of local endpoint still available for each msk"), e.g. on v5.15. Similar to commit d4c81bbb8600 ("selftests: mptcp: join: support local endpoint being tracked or not"), it is possible to add the new endpoint conditionally, by checking if "mptcp_pm_subflow_check_next" is present in kallsyms: this is not directly linked to the commit introducing this symbol but for the parent one which is linked anyway. So we can know in advance what will be the expected behaviour, and add the new endpoint only when it makes sense to do so.

It is nice to have a visual alignment in the test output to present the different results, but it makes less sense in the TAP output that is there for computers. It sounds then better to remove the duplicated whitespaces in the TAP output, also because it can cause some issues with TAP parsers expecting only one space around the directive delimiter (#).
