[PATCH bpf-next 00/15] use network helpers, part 11

[Geliang Tang <geliang@kernel.org>]

From: Geliang Tang <tanggeliang@kylinos.cn>

This set is part 11 of series "use network helpers" all BPF selftests
wide.

Finally something new in this set.

The helper make_sockaddr is extended to support sockets of AF_PACKET,
AF_ALG and AF_VSOCK families. Then these types of sockets can be used
to start_server_str() helper too.

Imitating connect_to_* interfaces, send_to_* interfaces are added to
support sendto() with given FD or the address string.

Add more conditions to control listen: nolisten flag, listen_support()
helper and clear "type" bits for listen.

Patch 1 for AF_UNIX socket:
    Patch 1 uses start_server_str for a AF_UNIX socket.

Patches 2-6 for AF_PACKET sockets:
    Patch 2 adds AF_PACKET support for make_sockaddr.
    Patch 3 uses start_server_str for a AF_PACKET socket.
    Patches 4-5 adds send_to_fd_opts/send_to_addr_str helpers.
    Patch 6 uses send_to_addr_str for a AF_PACKET socket.

Patches 7-9 for AF_ALG sockets:
    Patch 7 adds AF_ALG support for make_sockaddr.
    Patch 8 add nolisten flag, needed by patch 9.
    Patch 9 uses send_to_addr_str for a AF_ALG socket.

Patches 10-15 for AF_VSOCK sockets:
    Patch 10 adds AF_VSOCK support for make_sockaddr.
    Patches 11-12 uses make_sockaddr for AF_VSOCK sockets.
    Patches 13-14 adds more conditions to control listen.
    Patch 15 uses start_server_str for AF_VSOCK sockets.
