[Qemu-trivial] Problems with -net socket connect on windows

[M . Stein]

Hi,

FYI: I had problems with this, the error
message was:

connect: No error
D:\usr_win\bin\qemu.exe: -net socket,vlan=0,connect=127.0.0.1:56789:
Device 'socket' could not be initialized

I have done it with qemu 0.14 (win7-64/cygwin32/mingw),
but the recent code seems to be the same. The Solution
I have googled was, that one have to
ignore error WSAEISCONN on windows too.

For me it works now.

net/socket.c net_socket_connect_init:

    connected = 0;
    for(;;) {
        ret = connect(fd,
(struct sockaddr *)&saddr, sizeof(saddr));
        if (ret
< 0) {
           
err = socket_error();
           
if (err == EINTR || err == EWOULDBLOCK) {
           
} else if (err == EINPROGRESS) {
           
    break;
#ifdef _WIN32
           
} else if (err == WSAEALREADY || err == WSAEINVAL) {
           
    break;
*** added this lines ***
           
} else if (err == WSAEISCONN) {
         
      fprintf(stderr,"connect: ignore 'already connected'
error (on windows)\n");
           
    break;
*** end added ***
#endif
           
} else {
           
    perror("connect");
           
    closesocket(fd);
           
    return -1;
           
}
        } else {
           
connected = 1;
           
break;
        }

Hope, this helps more, than it makes
noise.
