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/if_xdp.h <-> bpf-next/tools/include/uapi/linux/if_xdp.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:

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
