Subject: [PATCH bpf-next v2 0/4] bpf: expose bpf_{g,s}etsockopt to more
 bpf_sock_addr hooks

We'd like to use the SENDMSG ones, Daniel suggested to
expose to more hooks while are here.

Stanislav Fomichev (4):
  bpf: enable bpf_{g,s}etsockopt in BPF_CGROUP_UDP{4,6}_SENDMSG
  bpf: enable bpf_{g,s}etsockopt in
    BPF_CGROUP_INET{4,6}_GET{PEER,SOCK}NAME
  selftests/bpf: rewrite readmsg{4,6} asm progs to c in test_sock_addr
  bpf: enable bpf_{g,s}etsockopt in BPF_CGROUP_UDP{4,6}_RECVMSG
