[PATCH bpf-next 00/12] Move ld_abs/ld_ind to native BPF

From: Daniel Borkmann <daniel@iogearbox.net>
Date: 2018-05-03 01:05:45

This set simplifies BPF JITs significantly by moving ld_abs/ld_ind
to native BPF, for details see individual patches. Main rationale
is in patch 'implement ld_abs/ld_ind in native bpf'. Thanks!

Daniel Borkmann (12):
  bpf: prefix cbpf internal helpers with bpf_
  bpf: migrate ebpf ld_abs/ld_ind tests to test_verifier
  bpf: implement ld_abs/ld_ind in native bpf
  bpf: add skb_load_bytes_relative helper
  bpf, x64: remove ld_abs/ld_ind
  bpf, arm64: remove ld_abs/ld_ind
  bpf, sparc64: remove ld_abs/ld_ind
  bpf, arm32: remove ld_abs/ld_ind
  bpf, mips64: remove ld_abs/ld_ind
  bpf, ppc64: remove ld_abs/ld_ind
  bpf, s390x: remove ld_abs/ld_ind
  bpf: sync tools bpf.h uapi header
