Subject: [PATCH bpf-next v4 00/12] bpf: sockmap, sockhash: support storing UDP sockets

I've adressed John's nit in patch 3, and added the reviews and acks.

Changes since v3:
- Clarify !psock check in sock_map_link_no_progs

Changes since v2:
- Remove sk_psock_hooks based on Jakub's idea
- Fix reference to tcp_bpf_clone in commit message
- Add inet_csk_has_ulp helper

Changes since v1:
- Check newsk->sk_prot in tcp_bpf_clone
- Fix compilation with BPF_STREAM_PARSER disabled
- Use spin_lock_init instead of static initializer
- Elaborate on TCPF_SYN_RECV
- Cosmetic changes to TEST macros, and more tests
- Add Jakub and me as maintainers

Lorenz Bauer (12):
  bpf: sockmap: only check ULP for TCP sockets
  skmsg: update saved hooks only once
  bpf: tcp: move assertions into tcp_bpf_get_proto
  bpf: tcp: guard declarations with CONFIG_NET_SOCK_MSG
  bpf: sockmap: move generic sockmap hooks from BPF TCP
  bpf: sockmap: simplify sock_map_init_proto
  bpf: add sockmap hooks for UDP sockets
  bpf: sockmap: add UDP support
  selftests: bpf: don't listen() on UDP sockets
  selftests: bpf: add tests for UDP sockets in sockmap
  selftests: bpf: enable UDP sockmap reuseport tests
  bpf, doc: update maintainers for L7 BPF
