Paolo Bonzini a245fc1835 net: consolidate NetClientState header files into one
This patch doesn't seem much useful alone, I must admit.  However,
it makes sense as part of the upcoming directory reorganization,
where I want to have include/net/tap.h as the net<->hw interface
for tap.  Then having both net/tap.h and include/net/tap.h does
not work.  "Fixed" by moving all the init functions to a single
header file net/clients.h.

The patch also adopts a uniform style for including net/*.h files
from net/*.c, without the net/ path.

Stefan Hajnoczi 45a7f54a8b net: EAGAIN handling for net/socket.c TCP
Replace spinning send_all() with a proper non-blocking send.  When the
socket write buffer limit is reached, we should stop trying to send and
wait for the socket to become writable again.

Non-blocking TCP sockets can return in two different ways when the write
buffer limit is reached:

1. ret = -1 and errno = EAGAIN/EWOULDBLOCK.  No data has been written.

2. ret < total_size.  Short write, only part of the message was
   transmitted.

Handle both cases and keep track of how many bytes have been written in
s->send_index.  (This includes the 'length' header before the actual
payload buffer.)

Stefan Hajnoczi 863f678fba net: asynchronous send/receive infrastructure for net/socket.c
The net/socket.c net client is not truly asynchronous.  This patch
borrows the qemu_set_fd_handler2() code from net/tap.c as the basis for
proper asynchronous send/receive.

Only read packets from the socket when the peer is able to receive.
This avoids needless queuing.

Later patches implement asynchronous send.

Stefan Hajnoczi 61518a74ca net: broadcast hub packets if at least one port can receive
In commit 60c07d933c ("net: fix
qemu_can_send_packet logic") the "VLAN" broadcast behavior was changed
to queue packets if any net client cannot receive.  It turns out that
this was not actually the right fix and just hides the real bug that
hw/usb/dev-network.c:usbnet_receive() clobbers its receive buffer when
called multiple times in a row.  The commit also introduced a new bug
that "VLAN" packets would not be sent if one of multiple net clients was
down.

The hw/usb/dev-network.c bug has since been fixed, so this patch reverts
broadcast behavior to send packets as long as one net client can
receive.  Packets simply get queued for the net clients that are
temporarily unable to receive.

Stefan Hajnoczi 06b5f36d05 net: do not report queued packets as sent
Net send functions have a return value where 0 means the packet has not
been sent and will be queued.  A non-zero value means the packet was
sent or an error caused the packet to be dropped.

This patch fixes two instances where packets are queued but we return
their size.  This causes callers to believe the packets were sent.  When
the caller uses the async send interface this creates a real problem
because the callback will be invoked for a packet that the caller
believed to be already sent.  This bug can cause double-frees in the
caller.

Paolo Bonzini 987a9b4800 net: notify iothread after flushing queue
virtio-net has code to flush the queue and notify the iothread
whenever new receive buffers are added by the guest.  That is
fine, and indeed we need to do the same in all other drivers.
However, notifying the iothread should be work for the network
subsystem.  And since we are at it we can add a little smartness:
if some of the queued packets already could not be delivered,
there is no need to notify the iothread.

Zhi Yong Wu 011de2b512 net: add the support for -netdev socket, listen
The -net socket,listen option does not work with the newer -netdev
syntax:
 http://lists.gnu.org/archive/html/qemu-devel/2011-11/msg01508.html

This patch makes it work now.

For the case where one vlan has multiple listenning sockets,
the patch will also provide the support.

Supported syntax:
 1.) -net socket,listen=127.0.0.1:1234,vlan=0
 2.) -net socket,listen=127.0.0.1:1234,vlan=0 -net socket,listen=127.0.0.1:1235,vlan=0
 3.) -netdev socket,listen=127.0.0.1:1234,id=socket0

 Drop the NetSocketListenState struct and add a listen_fd field
to NetSocketState.  When a -netdev socket,listen= instance is created
there will be a NetSocketState with fd=-1 and a valid listen_fd.  The
net_socket_accept() handler waits for listen_fd to become readable and
then accepts the connection.  When this state transition happens, we no
longer monitor listen_fd for incoming connections...until the client
disconnects again.

I transformed the code accordingly. The real fix would be to embed "fd",
"listen", "connect", "mcast" and "udp" in a separate union. However
OptsVisitor's enum parser only supports the type=XXX QemuOpt instance as
union discriminator.
