Subject: [PATCH bpf-next v2 0/4] Add get{peer,sock}name cgroup attach types

Trivial patch to add get{peer,sock}name cgroup attach types to the BPF
sock_addr programs in order to enable rewriting sockaddr structs from
both calls along with libbpf and bpftool support as well as selftests.

Thanks!

v1 -> v2:
  - use __u16 for ports in start_server_with_port() signature and in
    expected_{local,peer} ports in the test case (Andrey)
  - Added both Andrii's and Andrey's ACKs

Daniel Borkmann (4):
  bpf: add get{peer,sock}name attach types for sock_addr
  bpf, libbpf: enable get{peer,sock}name attach types
  bpf, bpftool: enable get{peer,sock}name attach types
  bpf, testing: add get{peer,sock}name selftests to test_progs
