bpf [general] (safe dynamic programs and tools), bpf [selftests] (test runners & infrastructure), kernel selftest framework, the rest, xdp (express data path) · Maintainers:
Alexei Starovoitov, Daniel Borkmann, Andrii Nakryiko, Eduard Zingerman, Kumar Kartikeya Dwivedi, Shuah Khan, Shuah Khan, Linus Torvalds, David S. Miller, Jakub Kicinski, Jesper Dangaard Brouer, John Fastabend
2 review trailers (1 from subsystem maintainers); queued in bpf-next as 5f65b7160634 on 2026-09-14.
Adopt the newly added bpf_program__add_flags() helper everywhere the selftests adds program flags (replacing all uses of bpf_program__set_flags() in the tests).
