Add support for various BPF prog types and attach types that have been added to
kernel recently but not to bpftool or libbpf yet.


Andrey Ignatov (3):
  bpftool: Add missing prog types and attach types
  libbpf: Support guessing post_bind{4,6} progs
  libbpf: Type functions for raw tracepoints

  Add missing prog types to `bpftool prog` and missing attach types to
  `bpftool cgroup`.

    Would you mind updating the man page in Documentation/ as well?

        Hi Andrey,
        
        In addition to the Documentation, there would also be the bash completion
        to update. The patch below should make it, please feel free to incorporate
        it to your changes if it seems alright to you. Otherwise I'll submit it as
        a follow-up.
        
        Quentin

  libbpf can guess prog type and expected attach type based on section
  name. Add hints for "cgroup/post_bind4" and "cgroup/post_bind6" section
  names.
  
  Existing "cgroup/sock" is not changed, i.e. expected_attach_type for it
  is not set to `BPF_CGROUP_INET_SOCK_CREATE`, for backward compatibility.

  Add missing pieces for BPF_PROG_TYPE_RAW_TRACEPOINT in libbpf:
  * is- and set- functions;
  * support guessing prog type.
