It relies on existing scripts/bpf_helpers_doc.py and include/uapi/linux/bpf.h having a well-defined set of comments. bpf_helper_defs.h contains all BPF helper signatures which stay in sync with latest bpf.h UAPI. This auto-generated header is included from bpf_helpers.h, while all previously hand-written BPF helper definitions are simultaneously removed in patch #3. The end result is less manually maintained and redundant boilerplate code, while also more consistent and well-documented set of BPF helpers. Generated helper definitions are completely independent from a specific bpf.h on a target system, because it doesn't use BPF_FUNC_xxx enums. v3->v4: - instead of libbpf's Makefile, integrate with selftest/bpf's Makefile (Alexei); v2->v3: - delete bpf_helper_defs.h properly (Alexei); v1->v2: - add bpf_helper_defs.h to .gitignore and `make clean` (Alexei). ==================== Signed-off-by: Alexei Starovoitov --- 05949f63055fcf53947886ddb8e23c8a5d41bd80
