Subject: [PATCH bpf v3 0/6] Fix unconnected bpf cgroup hooks

Please refer to the patch 1/6 as the main patch with the details
on the current sendmsg hook API limitations and proposal to fix
it in order to work with basic applications like DNS. Remaining
patches are the usual uapi and tooling updates as well as test
cases. Thanks a lot!

v2 -> v3:
  - Add attach types to test_section_names.c and libbpf (Andrey)
  - Added given Acks, rest as-is
v1 -> v2:
  - Split off uapi header sync and bpftool bits (Martin, Alexei)
  - Added missing bpftool doc and bash completion as well

Daniel Borkmann (6):
  bpf: fix unconnected udp hooks
  bpf: sync tooling uapi header
  bpf, libbpf: enable recvmsg attach types
  bpf, bpftool: enable recvmsg attach types
  bpf: more msg_name rewrite tests to test_sock_addr
  bpf: expand section tests for test_section_names
