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.

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
