[Qemu-devel] [RFC 0/4] Allow custom socket option in socket_listen and socket_connect

[Zihan Yang]

socket_listen and socket_connect do not allow custom socket option.
This would be inconvenient if the caller wants a non-blocking socket,
or wants to set TCP_NODELAY or other options.

This series of patches add specific config structures, QemuSocketConfig,
which contains QemuSocketOption. All the QemuSocketOption are formed
as a linked list.

The caller is reponsible for setting up the config structure. Passing
an NULL pointer would use the original socket_listen/socket_connect,
so existing functions are not affected.

Note that the caller needs to check errno after socket_connect when
using a non-blocking socket. It does not have to in other cases.

Zihan Yang (4):
  qemu-socket: Allow custom socket option in socket_listen
  qemu-socket: Allow custom socket options in socket_connect
  net/socket: change net_socket_listen_init to use functions in
    include/qemu/sockets.h
  net/socket: change net_socket_connect_init to use functions in
    sockets.h
