[Qemu-devel] [PATCH v2 0/3] net: asynchronous send/receive for net/socket.c

[Stefan Hajnoczi]

The net subsystem supports non-blocking sockets and asynchronous send/receive.
Unfortunately, net/socket.c doesn't fully take advantage of that yet.

This patch series makes send asynchronous and drops code that will spin when
the non-blocking socket would block.  Also take advantage of
qemu_set_fd_handler2()'s IOCanReadHandler so that we don't read packets from
the socket when our peer is unable to receive.

v2:
 * Use iov.h instead of readv()/writev() [Peter/Paolo]

Stefan Hajnoczi (3):
  net: asynchronous send/receive infrastructure for net/socket.c
  net: EAGAIN handling for net/socket.c UDP
  net: EAGAIN handling for net/socket.c TCP
