There's no requirement for RSDP to be installed last

  io: preserve ipv4/ipv6 flags when resolving InetSocketAddress
  sockets: ensure we don't accept IPv4 clients when IPv4 is disabled
  sockets: don't block IPv4 clients when listening on "::"
  sockets: ensure we can bind to both ipv4 & ipv6 separately
Signed-off-by: NPeter Maydell <peter.maydell@linaro.org>

The original InetSocketAddress struct may have has_ipv4 and
has_ipv6 fields set, which will control both the ai_family
used during DNS resolution, and later use of the V6ONLY
flag.

Currently the standalone DNS resolver code drops the
has_ipv4 & has_ipv6 flags after resolving, which means
the later bind() code won't correctly set V6ONLY.

This fixes the following scenarios

  -vnc :0,ipv4=off
  -vnc :0,ipv6=on
  -vnc :::0,ipv4=off
  -vnc :::0,ipv6=on

which all mistakenly accepted IPv4 clients

Currently if you disable listening on IPv4 addresses, via the
CLI flag ipv4=off, we still mistakenly accept IPv4 clients via
the IPv6 listener socket due to IPV6_V6ONLY flag being unset.

We must ensure IPV6_V6ONLY is always set if ipv4=off

This fixes the following scenarios

  -incoming tcp::9000,ipv6=on
  -incoming tcp:[::]:9000,ipv6=on
  -chardev socket,id=cdev0,host=,port=9000,server,nowait,ipv4=off

When inet_parse() parses the hostname, it is forcing the
has_ipv6 && ipv6 flags if the address contains a ":". This
means that if the user had set the ipv4=on flag, to try to
restrict the listener to just ipv4, an error would not have
been raised.  eg

   -incoming tcp:[::]:9000,ipv4

should have raised an error because listening for IPv4
on "::" is a non-sensical combination. With this removed,
we now call getaddrinfo() on "::" passing PF_INET and
so getaddrinfo reports an error about the hostname being
incompatible with the requested protocol:

 qemu-system-x86_64: -incoming tcp:[::]:9000,ipv4: address resolution
    failed for :::9000: Address family for hostname not supported

Likewise it is explicitly setting the has_ipv4 & ipv4
flags when the address contains only digits + '.'. This
has no ill-effect, but also has no benefit, so is removed.

When binding to an IPv6 socket we currently force the
IPV6_V6ONLY flag to off. This means that the IPv6 socket
will accept both IPv4 & IPv6 sockets when QEMU is launched
with something like

  -vnc :::1

While this is good for that case, it is bad for other
cases. For example if an empty hostname is given,
getaddrinfo resolves it to 2 addresses 0.0.0.0 and ::,
in that order. We will thus bind to 0.0.0.0 first, and
then fail to bind to :: on the same port. The same
problem can happen if any other hostname lookup causes
the IPv4 address to be reported before the IPv6 address.

When we get an IPv6 bind failure, we should re-try the
same port, but with IPV6_V6ONLY turned on again, to
avoid clash with any IPv4 listener.

This ensures that

  -vnc :1

will bind successfully to both 0.0.0.0 and ::, and also
avoid

  -vnc :1,to=2

from mistakenly using a 2nd port for the :: listener.

This is a regression due to commit 396f935a "ui: add ability to
specify multiple VNC listen addresses".

In QEMU, a guest VCPU always started in and never was able to leave
z/Architecture mode. Now we have an architected way of showing this
condition.

The SIGP SET ARCHITECTURE instruction is simply rejected. Linux as guest
seems to not care about the return value, which is a good thing
The new handling is just like already being in z/Architecture mode.

We'll not try to fake absence of this facility, but still not indicate
the facility in case some strange CPU model turned z/Architecture off
completely (which doesn't work either way but let's us see how a

model. Later they might be switched off due to applied real cpu model.
For ais bit, we only provide it in the full cpu model beginning with
zEC12 and defer its enablement in the default cpu model to a later point
in time. At the same time, disable them for 2.9 and older machines.

It's already possible to do a network boot of an s390x guest with an
external netboot image based on a Linux installation, but it would
be much more convenient if the s390-ccw firmware supported network
booting right out of the box, without the need to assemble such an
external image first.

This is an s390-netboot.img that can be used for network booting.
You can download a combined kernel + initrd image via TFTP
by starting QEMU for example with:

 qemu-system-s390x ... -device virtio-net,netdev=n1,bootindex=1 \
       -netdev user,id=n1,tftp=/path/to/tftp,bootfile=kernel.img

Currently the migration of the channel subsystem (css) is only partial
and is done by the virtio ccw proxies -- the only migratable css devices
existing at the moment.

With the current work on emulated and passthrough devices we need to
decouple the migration of the channel subsystem state from virtio ccw,
and have a separate section for it. A new section  however necessarily
breaks the migration compatibility.

So let us introduce a switch at the machine class, and put it in 'off'
state for now. We will turn the switch 'on' for future machines once all
preparations are met. For compatibility  machines the switch will stay
'off'.

We will need the machine class at machine initialization time, so the
usual way via qdev won't do. Let's cache the machine class and also use
the default values of the base machine for capability discovery.

Let's use the new inject_airq callback of flic to inject adapter
interrupts. For kvm case, if the kernel flic doesn't support the new
interface, the irq routine remains unchanged. For non-kvm case,
qemu-flic handles the suppression process.

Currently, we do nothing for the SIC instruction, but we need to
implement it properly. Let's add proper handling in the backend code.
