In this series from Geliang, modifying MPTCP BPF selftests, we have: - A new MPTCP subflow BPF program setting socket options per subflow: it looks better to have this old test program in the BPF selftests to track regressions and to serve as example. Note: Nicolas is no longer working for Tessares, but he did this work while working for them, and his email address is no longer available. - A new symlink to MPTCP's pm_nl_ctl tool is added in BPF selftests, to be able to use it instead of 'ip mptcp' which is not supported by the BPF CI running IPRoute 5.5.0. - A new MPTCP BPF subtest validating the new BPF program added in the first patch. Signed-off-by: Matthieu Baerts (NGI0) <matttbe@xxxxxxxxxx> --- Changes in v3: - Sorry for the delay between v2 and v3, this series was conflicting with the "add netns helpers", but it looks like it is on hold: https://lore.kernel.org/cover.1715821541.git.tanggeliang@xxxxxxxxxx - Patch 1/3 includes "bpf_tracing_net.h", introduced in between. - New patch 2/3: "selftests/bpf: Add mptcp pm_nl_ctl link". - Patch 3/3: use the tool introduced in patch 2/3 + SYS_NOFAIL() helper. - Link to v2: https://lore.kernel.org/r/20240509-upstream-bpf-next-20240506-mptcp-subflow-test-v2-0-4048c2948665@xxxxxxxxxx Changes in v2: - Previous patches 1/4 and 2/4 have been dropped from this series: - 1/4: "selftests/bpf: Handle SIGINT when creating netns": - A new version, more generic and no longer specific to MPTCP BPF selftest will be sent later, as part of a new series. (Alexei) - 2/4: "selftests/bpf: Add RUN_MPTCP_TEST macro": - Removed, not to hide helper functions in macros. (Alexei) - The commit message of patch 1/2 has been clarified to avoid some possible confusions spot by Alexei. - Link to v1: https://lore.kernel.org/r/20240507-upstream-bpf-next-20240506-mptcp-subflow-test-v1-0-e2bcbdf49857@xxxxxxxxxx --- Geliang Tang (2): selftests/bpf: Add mptcp pm_nl_ctl link selftests/bpf: Add mptcp subflow subtest Nicolas Rybowski (1): selftests/bpf: Add mptcp subflow example MAINTAINERS | 1 + tools/testing/selftests/bpf/Makefile | 3 +- tools/testing/selftests/bpf/mptcp_pm_nl_ctl.c | 1 + tools/testing/selftests/bpf/prog_tests/mptcp.c | 104 ++++++++++++++++++++++ tools/testing/selftests/bpf/progs/mptcp_subflow.c | 59 ++++++++++++ 5 files changed, 167 insertions(+), 1 deletion(-) --- base-commit: fd8db07705c55a995c42b1e71afc42faad675b0b change-id: 20240506-upstream-bpf-next-20240506-mptcp-subflow-test-faef6654bfa3 Best regards, -- Matthieu Baerts (NGI0) <matttbe@xxxxxxxxxx>
