Previous version of script relied on squashing baseline commit and rebasing rest of commits on top of it. This doesn't work well with git histories containing merges. This patch changes approach by cherry-picking commits that have libbpf-related changes and then rewriting history since last checkpoint. This still might fail if there were manually resolved merge conflicts for libbpf, but it's the best we can get as far as I can tell. Script now also verifies that state of libbpf in Linux's repository exactly matches the state of libbpf in github repo. If everything goes smoothing (including verification step), we clean up after ourselves and only leave libbpf-sync-XXX branch in github's libbpf repo to push to remote.

This is a mirror of bpf-next linux tree (https://kernel.googlesource.com/pub/scm/linux/kernel/git/bpf/bpf-next) bpf-next/tools/lib/bpf directory plus its supporting header files. The following files will by sync'ed with bpf-next repo: src/ <-> bpf-next/tools/lib/bpf/ include/uapi/linux/bpf_common.h <-> bpf-next/tools/include/uapi/linux/bpf_common.h include/uapi/linux/bpf.h <-> bpf-next/tools/include/uapi/linux/bpf.h include/uapi/linux/btf.h <-> bpf-next/tools/include/uapi/linux/btf.h include/uapi/linux/if_link.h <-> bpf-next/tools/include/uapi/linux/if_link.h include/uapi/linux/netlink.h <-> bpf-next/tools/include/uapi/linux/netlink.h include/tools/libc_compat.h <-> bpf-next/tools/include/tools/libc_compat.h Other header files at this repo (include/linux/*.h) are reduced versions of their counterpart files at bpf-next/tools/include/linux/*.h to make compilation successful. Build ===== To build static library libbpf.a: cd src make To build both static libbpf.a and shared libbpf.so libraries in directory build/ and install them together with libbpf headers in a staging directory root/: cd src mkdir build root BUILD_SHARED=y OBJDIR=build DESTDIR=root make install
