Optional feature detections complicate libbpf Makefile and cause more troubles for various applications that want to integrate libbpf as part of their build. Patch #1 replaces all reallocarray() uses into libbpf-internal reallocarray() implementation. Patches #2 and #3 makes sure we won't re-introduce reallocarray() accidentally. Patch #2 also removes last use of libbpf_internal.h header inside bpftool. There is still nlattr.h that's used by both libbpf and bpftool, but that's left for a follow up patch to split. Patch #4 removed libelf-mmap feature detector and all its uses, as it's trivial to handle missing mmap support in libbpf, the way objtool has been doing it for a while. v1->v2 and v2->v3: - rebase to latest bpf-next (Alexei). ==================== Signed-off-by: Alexei Starovoitov --- 37081156149fd532d534efd8ea99ca362ed62e5b
