[PATCH bpf v2 0/4] Fix unconnected bpf cgroup hooks

[Daniel Borkmann <daniel@iogearbox.net>]

Please refer to the patch 1/4 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!

v1 -> v2:
  - Split off uapi header sync and bpftool bits (Martin, Alexei)
  - Added missing bpftool doc and bash completion as well

Daniel Borkmann (4):
  bpf: fix unconnected udp hooks
  bpf: sync tooling uapi header
  bpf, bpftool: enable recvmsg attach types
  bpf: add further msg_name rewrite tests to test_sock_addr
