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 MPTCP BPF subtest validating the new BPF program added in the first patch. Signed-off-by: Matthieu Baerts (NGI0) --- Changes in v4: - Drop former patch 2/3: MPTCP's pm_nl_ctl requires a new header file: - I will check later if it is possible to avoid having duplicated header files in tools/include/uapi, but no need to block this series for that. Patch 2/3 can be added later if needed. - Patch 2/2: skip the test if 'ip mptcp' is not available. - Link to v3: https://lore.kernel.org/r/20240703-upstream-bpf-next-20240506-mptcp-subflow-test-v3-0-ebdc2d494049@kernel.org 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@kylinos.cn - 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@kernel.org 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@kernel.org --- Geliang Tang (1): selftests/bpf: Add mptcp subflow subtest Nicolas Rybowski (1): selftests/bpf: Add mptcp subflow example tools/testing/selftests/bpf/prog_tests/mptcp.c | 105 ++++++++++++++++++++++ tools/testing/selftests/bpf/progs/mptcp_subflow.c | 59 ++++++++++++ 2 files changed, 164 insertions(+) --- base-commit: 3d650ab5e7d9c4d7306e4c116f8aa9980bf13295 change-id: 20240506-upstream-bpf-next-20240506-mptcp-subflow-test-faef6654bfa3 Best regards,
