[Qemu-devel] [Bug 1196727] Re: SLIRP on Windows 7 64-bit host or is it me?

[Kenneth Salerno]

I confirmed it wasn't my host, I successfully ran a test on the same
host with a 32-bit QEMU build and SLIRP works fine, for 1.6.0-rc3 as
well.

It could be my x86_64-w64-mingw32-gcc compiler version, I tested 4.8 and
4.7, maybe they're too new? Is there a specific gcc version known to
work? I can build a new cross-compiler if need be.

The reason I want the 64-bit build to work is to raise the guest memory.

  SLIRP on Windows 7 64-bit host or is it me?

      Guest: FreeBSD 9.1 i386, RHEL 6.4 x86_64, SLES 11.2 x86_64, OpenSUSE 12.3

  I'm new to Windows 7 64-bit as a host for QEMU (previously I was
  running QEMU on Windows XP with no issues) so it could be me, now on
  Windows 7 SLIRP only works for me connecting internally from the host
  to the guest via SLIRP redirect, but any outbound requests from the
  guest to the Internet are failing with the following:

  if_start...
  m_get...
   m = 61f7bd40
  ip_input...
   m = 61f7bd40
   m_len = 48
  tcp_input...
   m = 61f7bd40  iphlen = 20  inso = 0
  tcp_fconnect...
   so = 33e140
   connect()ing, addr.sin_port=80, addr.sin_addr.s_addr=206.190.36.45

   ip = 0x502000a
   found hw addr = 52:54:00:12:34:56
  m_free...
   m = 61f7b6c0
  tcp_close...
   tp = 377840
  m_free...
   m = 0
  m_free...
   m = 61f7bd40

  Am I doing something wrong with my Windows host configuration or is
  this a bug in SLIRP only on W64 and not W32?
