Matthieu Baerts says: ==================== 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 at Tessares, but he did this work while working for them, and his email address is no longer available. - A new hook in the same BPF program to do the verification step. - A new MPTCP BPF subtest validating the new BPF program added in the first patch, with the help of the new hook added in the second patch. --- Changes in v7: - Patch 2/3: use 'can_loop' instead of 'cond_break'. (Martin) - Patch 3/3: use bpf_program__attach_cgroup(). (Martin) - Link to v6: https://lore.kernel.org/r/20240911-upstream-bpf-next-20240506-mptcp-subflow-test-v6-0-7872294c466b@kernel.org Changes in v6: - Patch 3/3: use usleep() instead of sleep() - Series: rebased on top of bpf-next/net - Link to v5: https://lore.kernel.org/r/20240910-upstream-bpf-next-20240506-mptcp-subflow-test-v5-0-2c664a7da47c@kernel.org Changes in v5: - See the individual changelog for more details about them - Patch 1/3: set TCP on the 2nd subflow - Patch 2/3: new - Patch 3/3: use the BPF program from patch 2/3 to do the validation instead of using ss. - Series: rebased on top of bpf-next/net - Link to v4: https://lore.kernel.org/r/20240805-upstream-bpf-next-20240506-mptcp-subflow-test-v4-0-2b4ca6994993@kernel.org 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 (2): selftests/bpf: Add getsockopt to inspect mptcp subflow selftests/bpf: Add mptcp subflow subtest ==================== Signed-off-by: Martin KaFai Lau <martin.lau@kernel.org> |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
