Subject: [Qemu-devel] [PATCH v2 0/3] net: asynchronous send/receive for net/socket.c
Date: Tue, 21 Aug 2012 16:52:28 +0100	[thread overview]
Message-ID: <1345564351-14693-1-git-send-email-stefanha@linux.vnet.ibm.com> (raw)

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]

  net: EAGAIN handling for net/socket.c UDP
  net: EAGAIN handling for net/socket.c TCP
