Fix the check preventing calling pixman functions that would access
memory outside allocated vram. The r128 X driver sometimes seem to try
blits that span outside vram, this check prevents crashing QEMU in
that case. (The r128 X driver may have problems even on real hardware
so I'm not sure if it's a client bug or emulation problem but at least
QEMU should survive.)
The SPICE_RING_PROD_ITEM() macro is initializing a local
'uint64_t *' variable to point to the 'el' field inside
the QXLReleaseRing struct. This uint64_t field is not
guaranteed aligned as the struct is packed.
Code should not take the address of fields within a
packed struct. Changing the SPICE_RING_PROD_ITEM()
macro to avoid taking the address of the field is
impractical. It is clearer to just remove the macro
and inline its functionality in the three call sites
that need it.

scripts/qemu.py: support adding a console with the default serial device
The set_console() utility function either adds a device based on the
explicitly given device type, or adds a known good type of device
based on the machine type.
But, for a number of machine types, it may be impossible or
inconvenient to add the devices by means of "-device" command line
options, and then it may better to just use the "-serial" option and
let QEMU itself, based on the machine type, set the device
accordingly.
To achieve that, the behavior of set_console() now flags the intention
to add a console device on launch(), and if no explicit device type is
given the "-serial" option is going to be added to the QEMU command
line, instead of raising exceptions.
Based on testing with different machine types, the CONSOLE_DEV_TYPES
is not necessary anymore, so it's being removed, as is the logic to
use it.

tests/acceptance: look for target architecture in test tags first
A test can, optionally, be tagged for one or many architectures. If a
test has been tagged for a single architecture, there's a high chance
that the test won't run on other architectures. This changes the
default order of choosing a default target architecture to use based
on the 'arch' tag value first.
The precedence order is for choosing a QEMU binary to use for a test
is now:
* qemu_bin parameter
* arch parameter
* arch tag value (for example, x86_64 if ":avocado: tags=arch:x86_64
is used)
This means that if one runs:
$ avocado run -p qemu_bin=/usr/bin/qemu-system-x86_64 test.py
No arch parameter or tag will influence the selection of the QEMU
target binary. If one runs:
$ avocado run -p arch=ppc64 test.py
The target binary selection mechanism will attempt to find a binary
such as "ppc64-softmmu/qemu-system-ppc64". And finally, if one runs
a test that is tagged (in its docstring) with "arch:aarch64":
$ avocado run aarch64.py
The target binary selection mechanism will attempt to find a binary
such as "aarch64-softmmu/qemu-system-aarch64".
At this time, no provision is made to cancel the execution of tests if
the arch parameter given (manually) does not match the test "arch"
tag, but it may be a useful default behavior to be added in the
future.

tests/acceptance: use "arch:" tag to filter target specific tests
Currently, some tests contains target architecture information, in the
form of a "x86_64" tag. But that tag is not respected in the default
execution, that is, "make check-acceptance" doesn't do anything with
it.
That said, even the target architecture handling currently present in
the "avocado_qemu.Test" class is pretty limited. For instance, by
default, it chooses a target based on the host architecture.
Because the original implementation of the tags feature in Avocado did
not include any time of namespace or "key:val" mechanism, no tag has
relation to another tag. The new implementation of the tags feature
from version 67.0 onwards, allows "key:val" tags, and because of that,
a test can be classified with a tag in a given key. For instance, the
new proposed version of the "boot_linux_console.py" test, which
downloads and attempts to run a x86_64 kernel, is now tagged as:
:avocado: tags=arch:x86_64
This means that it can be filtered (out) when no x86_64 target is
available. At the same time, tests that don't have a "arch:" tag,
will not be filtered out.

tests/acceptance: introduce arch parameter and attribute
It's useful to define the architecture that should be used in
situations such as:
* the intended target of the QEMU binary to be used on tests
* the architecture of code to be run within the QEMU binary, such
as a kernel image or a full blown guest OS image
This commit introduces both a test parameter and a test instance
attribute, that will contain such a value.
Now, when the "arch" test parameter is given, it will influence the
selection of the default QEMU binary, if one is not given explicitly
by means of the "qemu_img" parameter.

Some functions of the pci-host devices miss to drop one of the references.

the issue until they submit their patches and suddenly patchew or a
maintainer complains.
Now that we do not urgently need to keep the code clean from typedef
redefintions anymore with recent versions of GCC, we can ease the
situation with clang, too, and simply shut these warnings off for good.

usb-mtp: change default to success for usb_mtp_update_object
Commit c5ead51f90cf (usb-mtp: return incomplete transfer on a lstat
failure) checks if lstat succeeded when updating attributes of a
file. However, it also changed behavior to return an error by
default. This is incorrect because for smaller file sizes, Qemu
will attempt to write the file in one go and there won't be
an object for it.
usb-mtp: fix alignment of access of ObjectInfo filename field
The ObjectInfo struct's "filename" field is following a uint8_t
field in a packed struct and thus has bad alignment for a 16-bit
field. Switch the field to to uint8_t and use the helper function
for accessing unaligned 16-bit data.
Note that although the MTP spec specifies big endian, when transported
over the USB protocol, data is little endian.

qcow2: Fix error handling in the compression code
This patch fixes a few things in the way error codes are handled in
the qcow2 compression code:
a) qcow2_co_pwritev_compressed() expects qcow2_co_compress() to only
return -1 or -2 on failure, but this is not correct. Since the
change from qcow2_compress() to qcow2_co_compress() in commit ceb029cd6feccf9f7607 the new code can also return -EINVAL (although
there does not seem to exist any code path that would cause that
error in the current implementation).
b) -1 and -2 are ad-hoc error codes defined in qcow2_compress().
This patch replaces them with standard constants from errno.h.
c) Both qcow2_compress() and qcow2_co_do_compress() return a negative
value on failure, but qcow2_co_pwritev_compressed() stores the
value in an unsigned data type.

qcow2: Fix qcow2_make_empty() with external data file
make_completely_empty() is an optimisated path for bdrv_make_empty()
where completely new metadata is created inside the image file instead
of going through all clusters and discarding them. For an external data
file, however, we actually need to do discard operations on the data
file; just overwriting the qcow2 file doesn't get rid of the data.
The necessary slow path with an explicit discard operation already
exists for other cases. Use it for external data files, too.

preallocate_co() already gave the data file the full size without

bdrv_co_truncate() was called later with the preallocation mode, the
file didn't actually grow any more, so the data file stayed unallocated
even if full preallocation was requested.
Pass the right preallocation mode to preallocate_co() and remove the
second bdrv_co_truncate() to fix this. As a side effect, the ugly
one-byte write in preallocate_co() is replaced with a truncate call,
now leaving the last block unallocated on the protocol level as it

'T', while the other avoids overflow and goes all the way to 'E'. With
this patch, the output now claims 8EiB instead of -8388607T, which
really is the correct rounding of largest file size supported by qemu

of rounding up to the next sector boundary, but that wouldn't change

Commit b69864e5a ("vmdk: Support version=3 in VMDK descriptor files")
fixed the probe function to correctly guess vmdk descriptors with

This solves the issue where vmdk snapshot with parent vmdk descriptor
containing "version=3" would be treated as raw instead vmdk.
In the future case where a new vmdk version is introduced, we will again
experience this issue, even if the user will provide "-f vmdk" it will
only apply to the tip image and not to the underlying "misprobed" parent
image.
The code in vmdk.c already assumes that the backing file of vmdk must be
vmdk (see vmdk_is_cid_valid which returns 0 if backing file is not
vmdk).
So let's make it official by supplying the backing_format as vmdk.

The reproducer I used is a qcow2 image on gluster volume, where the
virtual disk size (4 GB) is larger than the gluster volume size (64M),
so we can easily trigger an ENOSPC. This backend is assigned to a
virtio-blk device using an iothread, and then from the guest a
'dd if=/dev/zero of=/dev/vda bs=1G count=1' causes the VM to stop
because of an I/O error. qemu_gluster_co_flush_to_disk() sets
bs->drv = NULL on error, so when virtio-blk stops the dataplane, the
block nodes stay in the iothread AioContext. A 'quit' monitor command
issued from this paused state crashes the process.

tests/qemu-iotests: Fix output of qemu-io related tests
One of the recent commits changed the way qemu-io prints out its
errors and warnings - they are now prefixed with the program name.
We've got to adapt the iotests accordingly to prevent that they
are failing.
