qemu-img: Check for backing image if specified during create
Or, rather, force the open of a backing image if one was specified
for creation. Using a similar -unsafe option as rebase, allow qemu-img

It may not always be possible, as in the existing case when a filesize
for the new image was not specified.
This is accomplished by shifting around the conditionals in
bdrv_img_create, such that a backing file is always opened unless we
provide BDRV_O_NO_BACKING. qemu-img is adjusted to pass this new flag
when -u is provided to create.

blockdev: move BDRV_O_NO_BACKING option forward
For both external_snapshot_prepare and qmp_drive_mirror, we eventually
append the option BDRV_O_NO_BACKING. However, we generally do so after
we create the image.
To accommodate image creation wanting to verify that a backing file
exists or not, add this option prior to create to override checking
the existence of the backing file. This prevents QEMU from trying to
re-open a backing file that's already in use (thanks to qcow2 locking).

block/vvfat: Fix compiler warning with gcc 7
gcc 7 complains that the sprintf() might write a null byte beyond the
end of the tail buffer. That is wrong, but we can silence it by making
i unsigned (it can never be negative anyway, see the if condition right
before). For some reason, this allows gcc to suddenly accurately
calculate the range of i so we can give the tail[] array the exact size
it needs to have (which is 8 bytes) without gcc complaining.
In addition, let us convert the sprintf() to snprintf(), because that is
always nicer, and add an assertion about the range of the return value
afterwards so we can see that "8 - len" will never be negative and thus
"entry->name + MIN(j, 8 - len)" will never be out of bounds.

- Use reStructuredText as markup language (with the goal of generating
the HTML output using the Sphinx Documentation Generator). It is
gentler on the eye, and can be trivially converted to different
formats. (Another reason: upstream QEMU is considering to switch to
Sphinx, which uses reStructuredText as its markup language.)
- Raw QMP JSON output vs. 'qmp-shell'. I debated with myself whether
to only show raw QMP JSON output (as that is the canonical
representation), or use 'qmp-shell', which takes key-value pairs. I
settled on the approach of: for the first occurrence of a command,
use raw JSON; for subsequent occurrences, use 'qmp-shell', with an
occasional exception.
- Usage of `-blockdev` command-line.
- Usage of 'node-name' vs. file path to refer to disks. While we have
`blockdev-{mirror, backup}` as 'node-name'-alternatives for
`drive-{mirror, backup}`, the `block-commit` command still operates
on file names for parameters 'base' and 'top'. So I added a caveat
at the beginning to that effect.
Refer this related thread that I started (where I learnt
`block-stream` was recently reworked to accept 'node-name' for 'top'
and 'base' parameters):
https://lists.nongnu.org/archive/html/qemu-devel/2017-05/msg06466.html

nbd: Fix server reply to NBD_OPT_EXPORT_NAME of older clients
A typo in commit 23e099c set the size of buf[] used in response
to NBD_OPT_EXPORT_NAME according to the length needed for old-style
negotiation (4 bytes of flag information) instead of the intended
2 bytes used in new style. If the client doesn't enable
NBD_FLAG_C_NO_ZEROES, then the server sends two bytes too many,
and is then out of sync in response to the client's next command
(the bug is masked when modern qemu is the client, since we enable
the no zeroes flag).
While touching this code, add some more defines to nbd_internal.h
rather than having quite so many magic numbers in the .c; also,
use "" initialization rather than memset(), and tweak the oldstyle
negotiation to better match the spec description of the layout
(since the spec is big-endian, skipping two bytes as 0 followed by
writing a 2-byte flag is the same as writing a zero-extended 4-byte

target/s390x: Allow to enable "idtes" feature for TCG
STFL bit 4 and 5 are just indications to the guest, which TLB entries an
IDTE call will clear. These are performance indicators for the guest.
STFL bit 4:
INVALIDATE DAT TABLE ENTRY (IDTE) performs
the invalidation-and-clearing operation by
selectively clearing TLB segment-table entries
when a segment-table entry or entries are
invalidated. IDTE also performs the clearing-by-
ASCE operation. Unless bit 4 is one, IDTE simply
purges all TLBs. Bit 3 is one if bit 4 is one.
We can simply set STFL bit 4 ("idtes") and still purge the complete TLB.
Purging more than advertised is never bad. E.g. Linux doesn't even care
about this bit. We can optimized this later.
This is helpful, as the z9 base model contains this facility.
STFL bit 5 (clearing TLB region-table-entries) was never implemented on
real HW, therefore we can simply ignore it for now.

nbd: Fix iotests failure due to changed client error message
Commit 8ecaeae8 changed the way the client requests an NBD export,
and in the process also changed the resulting error message when
the export is not present, breaking a couple of iotests. The error
message is now directly given by the server (a failed NBD_OPT_GO)
instead of implied by the client (after exhausting NBD_OPT_LIST),
but looking at the testsuite changes, it proves worthwhile to
reword the error message to be slightly less verbose (as this is
one particular error message likely to be hit by a user).
Note that the error message is now sensitive to which binary is
running the server as well as the client (since the expected
output is replaying a message received from the server - for that
matter, it depends on a server new enough to understand NBD_OPT_GO);
in general iotests are run on client and server from the same source
code base so the default setup will pass; but if it proves
problematic for people overriding QEMU_PROG, QEMU_IMG_PROG,
QEMU_IO_PROG, and QEMU_NBD_PROG to point across multiple builds for
cross-version integration testing, we may have to later tweak or
sanitize the output somehow.

i386: expose "TCGTCGTCGTCG" in the 0x40000000 CPUID leaf
Currently when running KVM, we expose "KVMKVMKVM\0\0\0" in
the 0x40000000 CPUID leaf. Other hypervisors (VMWare,
HyperV, Xen, BHyve) all do the same thing, which leaves
TCG as the odd one out.
The CPUID signature is used by software to detect which
virtual environment they are running in and (potentially)
change behaviour in certain ways. For example, systemd
supports a ConditionVirtualization= setting in unit files.
The virt-what command can also report the virt type it is
running on
Currently both these apps have to resort to custom hacks
like looking for 'fw-cfg' entry in the /proc/device-tree
file to identify TCG.
This change thus proposes a signature "TCGTCGTCGTCG" to be
reported when running under TCG.
To hide this, the -cpu option tcg-cpuid=off can be used.

fw_cfg: move qdev_init_nofail() from fw_cfg_init1() to callers
When looking to instantiate a TYPE_FW_CFG_MEM or TYPE_FW_CFG_IO device to be
able to wire it up differently, it is much more convenient for the caller to
instantiate the device and have the fw_cfg default files already preloaded
during realize.
Move fw_cfg_init1() to the end of both the fw_cfg_mem_realize() and
fw_cfg_io_realize() functions so it no longer needs to be called manually
when instantiating the device, and also rename it to fw_cfg_common_realize()
which better describes its new purpose.
Since it is now the responsibility of the machine to wire up the fw_cfg device
it is necessary to introduce a object_property_add_child() call into
fw_cfg_init_io() and fw_cfg_init_mem() to link the fw_cfg device to the root
machine object as before.
Finally with the previous change to fw_cfg_find() we can now remove the
assert() preventing multiple fw_cfg devices being instantiated and replace
them with a simple call to fw_cfg_find() at realize time instead. This allows
us to remove FW_CFG_NAME and FW_CFG_PATH since they are no longer required.

qdev: fix the order compat and global properties are applied
The current code recursively applies global properties from child up to
parent types. This can cause properties passed with the -global option to
be silently overridden by internal compat properties.
This is exactly what happened with virtio-*-pci drivers since commit:
Passing -device virtio-blk-pci.disable-modern=off had no effect on 2.6
machine types because the internal virtio-pci.disable-modern=on compat
property always prevailed.
A workaround for this was included with commit 0bcba41f ("machine:
Convert abstract typename on compat_props to subclass names").
This patch fixes the issue properly by reversing the logic: we now go
through the global property list and, for each property, we check if it
is applicable to the device.
This results in compat properties being applied first, in the order they
appear in the HW_COMPAT_* macros, followed by global properties, in the
order they appear on the command line.
At the moment VFIO PCI device initialization works as follows:
vfio_realize
vfio_get_group
vfio_connect_container
register memory listeners (1)
update QEMU groups lists
vfio_kvm_device_add_group
Then (example for pseries) the machine reset hook triggers region_add()
for all regions where listeners from (1) are listening:
This scheme works fine until we need to handle VFIO PCI device hotplug
and we want to enable PPC64/sPAPR in-kernel TCE acceleration on,
i.e. after PCI hotplug we need a place to call
ioctl(vfio_kvm_device_fd, KVM_DEV_VFIO_GROUP_SET_SPAPR_TCE).
Since the ioctl needs a LIOBN fd (from sPAPRTCETable) and a IOMMU group fd
(from VFIOGroup), vfio_listener_region_add() seems to be the only place
for this ioctl().
However this only works during boot time because the machine reset
happens strictly after all devices are finalized. When hotplug happens,
vfio_listener_region_add() is called when a memory listener is registered
but when this happens:
1. new group is not added to the container->group_list yet;
2. VFIO KVM device is unaware of the new IOMMU group.
This moves bits around to have all necessary VFIO infrastructure
in place for both initial startup and hotplug cases.
[aw: ie, register vfio groups with kvm prior to memory listener
registration such that kvm-vfio pseudo device ioctls are available
during the region_add callback]
