virtio-9p-device: add minimal unrealize handler
Since commit
4652f1640e029e1f2433fa77ba6af285 "virtio-9p: add savevm
handlers", if the user hot-unplugs a quiescent 9p device and live
migrates, the source QEMU crashes before migration completetion...
This happens because virtio-9p devices have a realize handler which
calls virtio_init() and register_savevm(). Both calls store pointers
to the device internals, that get dereferenced during migration even
if the device got unplugged.
This patch simply adds an unrealize handler to perform minimal
cleanup and avoid the crash. Hot unplug of non-quiescent 9p devices
is still not supported in QEMU, and not supported by linux guests
either.

e1000: fix hang of win2k12 shutdown with flood ping
e1000 driver in Win2k12 is really well rotten. It 100% hangs on shutdown
of UP VM under flood ping. The guest checks card state and reinjects
itself interrupt in a loop. This is fatal for UP machine.
There is no good way to fix this misbehavior but to kludge it. The
emulation has interrupt throttling register aka ITR which limits
interrupt rate and allows the guest to proceed this phase.
There is no problem with this kludge for Linux guests - it adjust the
value of it itself.

The original sin is commit 49ee359: its qtest_add_func() is a wrapper

g_test_add_func()'s. This uncovers type errors in ide-test.c; fix

configure: use appropriate code fragment for -fstack-protector checks
The check for stack-protector support consisted in compiling and linking
the test program below (output by function write_c_skeleton()) with the
compiler flag -fstack-protector-strong first and then with
-fstack-protector-all if the first one failed to work:
int main(void) { return 0; }
This caused false positives when using certain toolchains in which the
compiler accepted -fstack-protector-strong but no support was provided
by the C library, since for this stack-protector variant the compiler
emits canary code only for functions that meet specific conditions
(local arrays, memory references to local variables, etc.) and the code
fragment under test included none of them (hence no stack protection
code generated, no link failure).

ui: vnc: avoid floating point exception
While sending 'SetPixelFormat' messages to a VNC server,
the client could set the 'red-max', 'green-max' and 'blue-max'
values to be zero. This leads to a floating point exception in
write_png_palette while doing frame buffer updates.

util/mmap-alloc: fix hugetlb support on ppc64
Since commit
8561c9244ddf1122d "exec: allocate PROT_NONE pages on top of
RAM", it is no longer possible to back guest RAM with hugepages on ppc64
hosts:
mmap(NULL,
285212672, PROT_NONE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) =
0x3fff57000000
mmap(0x3fff57000000,
268435456, PROT_READ|PROT_WRITE,
MAP_PRIVATE|MAP_FIXED, 19, 0) = -1 EBUSY (Device or resource busy)
This is because on ppc64, Linux fixes a page size for a virtual address
at mmap time, so we can't switch a range of memory from anonymous
small pages to hugetlbs with MAP_FIXED.
See commit
d0f13e3c20b6fb73ccb467bdca97fa7cf5a574cd
("[POWERPC] Introduce address space "slices"") in Linux
history for the details.
Detect this and create the PROT_NONE mapping using the same fd.
Naturally, this makes the guard page bigger with hugetlbfs.

virtio-pci: Set the QEMU_PCI_CAP_EXPRESS capability early in its DeviceClass realize method
In 1811e64 'hw/virtio: Add PCIe capability to virtio devices', the
QEMU_PCI_CAP_EXPRESS capability was added to virtio's pci_dev, within
'virtio_pci_realize' - the pci device object realization method.
This occurs to late, as 'pci_qdev_realize' (DeviceClass.realize of
TYPE_PCI_DEVICE) has already been called, without knowing that the
device instance is indeed an "express" instance, thus allocating
insufficient pci config space.
As a result, device may crash upon attempt to write to the PCIE config
space.
Fix, by arming the QEMU_PCI_CAP_EXPRESS capability early in virtio-pci's
own DeviceClass realize method.
This also makes code cleaner, as 'virtio_pci_realize' may now access the
'pci_is_express' predicate when needed.

virtio: handle non-virtio-1-capable backend for ccw
If you run a qemu advertising VERSION_1 with an old kernel where
vhost did not yet support VERSION_1, you'll end up with a device
that is {modern pci|ccw revision 1} but does not advertise VERSION_1.
This is not a sensible configuration and is rejected by the Linux
guest drivers.
To fix this, add a ->post_plugged() callback invoked after features
have been queried that can handle the VERSION_1 bit being withdrawn
and change ccw to fall back to revision 0 if VERSION_1 is gone.
Note that pci is _not_ fixed; we'll need to rethink the approach

In that patch sizes are masked against qemu_host_page_size/mask which
are uintptr_t, and thus 32bit on a 32bit QEMU, even though the ram space
might be bigger than 4GB on Xen.
Since ram_addr_t is not available on user-mode emulation targets, ensure
that we get a sign extension when masking away the low bits of the address.
Remove the ~10 year old scary comment that the type of these variables
is probably wrong, with another equally scary comment. The new comment
however does not have "???" in it, which is arguably an improvement.

s390x/pci: fix up IOMMU size
Present code uses @size==UINT64_MAX to initialize IOMMU. It infers that it
can map any 64-bit IOVA whatsoever. But in fact, the largest DMA range for
each PCI Device on s390x is from ZPCI_SDMA_ADDR to ZPCI_EDMA_ADDR. The largest
value is returned from hardware, which is to indicate the largest range
hardware can support. But the real IOMMU size for specific PCI Device is
obtained once qemu intercepts mpcifc instruction that guest is requesting a
DMA range for that PCI Device. Therefore, before intercepting mpcifc instruction,
qemu cannot be aware of the size of IOMMU region that guest will use.
Moreover, iommu replay during device initialization for the whole region in
4k steps takes a very long time.
In conclusion, this patch intializes IOMMU region for each PCI Device when
intercept mpcifc instruction which is to register DMA range for the PCI Device.
And then, destroy IOMMU region when guest wants to deregister IOAT.

tap-win32: disable broken async write path
The code under the TUN_ASYNCHRONOUS_WRITES path makes two incorrect
assumptions about the behaviour of the WriteFile API for overlapped
file handles. First, WriteFile does not update the
lpNumberOfBytesWritten parameter when the write completes
asynchronously (the number of bytes written is known only when the
operation completes). Second, the buffer shouldn't be touched (or
freed) until the operation completes. This led to at least one bug
where tap_win32_write returned zero bytes written, which in turn
caused further writes ("receives") to be disabled for that device.
This change disables the asynchronous write path, while keeping most
of the code around in case someone sees value in resurrecting it. It
also adds some conditional debug output, similar to the read path.

Revert "exec: silence hugetlbfs warning under qtest"
This reverts commit
1c7ba94a184df1eddd589d5400d879568d3e5d08.
That commit changed QEMU initialization order from
- object-initial, chardev, qtest, object-late
to
- chardev, qtest, object-initial, object-late
This breaks chardev setups which need to rely on objects
having been created. For example, when chardevs use TLS
encryption in the future, they need to have tls credential
objects created first.
This revert, restores the ordering introduced in
commit
