1. do graph modifications ignoring permissions
2. do permission update

Recently we've fixed a crash by adding .get_parent_aio_context handler
to child_vvfat_qcow. Now we want it to support .get_parent_desc as
well. child_vvfat_qcow wants to implement own .inherit_options, it's
not bad. But omitting all other handlers is a bad idea. Let's inherit
the class from child_of_bds instead, similar to chain_child_class and
detach_by_driver_cb_class in test-bdrv-drain.c.

We have different types of parents: block nodes, block backends and
jobs. So, it makes sense to specify type together with name.
Next, this handler us used to compose an error message about permission
conflict. And permission conflict occurs in a specific place of block
graph. We shouldn't report name of parent device (as it refers another
place in block graph), but exactly and only the name of the node. So,
use bdrv_get_node_name() directly.

If fallocate(... FALLOC_FL_ZERO_RANGE ...) returns EINVAL, it's likely
an indication that the file system is buggy and does not implement
unaligned accesses right. We still might be lucky with the other
fallback fallocate() calls later in this function, though, so we should
not return immediately and try the others first.
Since FALLOC_FL_ZERO_RANGE could also return EINVAL if the file descriptor
is not a regular file, we ignore this filesystem bug silently, without
printing an error message for the user.

A customer reported that running
qemu-img convert -t none -O qcow2 -f qcow2 input.qcow2 output.qcow2
fails for them with the following error message when the images are
stored on a GPFS file system :
qemu-img: error while writing sector 0: Invalid argument
After analyzing the strace output, it seems like the problem is in
handle_aiocb_write_zeroes(): The call to fallocate(FALLOC_FL_PUNCH_HOLE)
returns EINVAL, which can apparently happen if the file system has
a different idea of the granularity of the operation. It's arguably
a bug in GPFS, since the PUNCH_HOLE mode should not result in EINVAL
according to the man-page of fallocate(), but the file system is out
there in production and so we have to deal with it. In commit 294682cc3a
("block: workaround for unaligned byte range in fallocate()") we also
already applied the a work-around for the same problem to the earlier
fallocate(FALLOC_FL_ZERO_RANGE) call, so do it now similar with the
PUNCH_HOLE call. But instead of silently catching and returning
-ENOTSUP (which causes the caller to fall back to writing zeroes),
let's rather inform the user once about the buggy file system and
try the other fallback instead.

It's wrong to rely on s->qcow in vvfat_child_perm, as on permission
update during bdrv_open_child() call this field is not set yet.
Still prior to aa5a04c7db, it didn't
crash, as bdrv_open_child passed NULL as child to bdrv_child_perm(),
and NULL was equal to NULL in assertion (still, it was bad guarantee
for child being s->qcow, not backing :).
Since aa5a04c7db
"add bdrv_attach_child_noperm" bdrv_refresh_perms called on parent node
when attaching child, and new correct child pointer is passed to
.bdrv_child_perm. Still, s->qcow is NULL at the moment. Let's rely only
on role instead.

The quorum block driver uses a custom flush callback to handle the
case when some children return io errors. In that case it still
returns success if enough children are healthy.
However, it provides it as the .bdrv_co_flush_to_disk callback, not
as .bdrv_co_flush. This causes the block layer to do it's own
generic flushing for the children instead, which doesn't handle
errors properly.
Fix this by providing .bdrv_co_flush instead of
.bdrv_co_flush_to_disk so the block layer uses the custom flush
callback.

The SEV FW >= 0.23 added a new command that can be used to query the
attestation report containing the SHA-256 digest of the guest memory
and VMSA encrypted with the LAUNCH_UPDATE and sign it with the PEK.
Note, we already have a command (LAUNCH_MEASURE) that can be used to
query the SHA-256 digest of the guest memory encrypted through the
LAUNCH_UPDATE. The main difference between previous and this command
is that the report is signed with the PEK and unlike the LAUNCH_MEASURE
command the ATTESATION_REPORT command can be called while the guest
is running.
Add a QMP interface "query-sev-attestation-report" that can be used
to get the report encoded in base64.

Hyper-V feature leaves are weird. We have some of them in
feature_word_info[] array but we don't use feature_word_info
magic to enable them. Neither do we use feature_dependencies[]
mechanism to validate the configuration as it doesn't allign
well with Hyper-V's many-to-many dependency chains. Some of
the feature leaves hold not only feature bits, but also values.
E.g. FEAT_HV_NESTED_EAX contains both features and the supported
Enlightened VMCS range.
Hyper-V features are already represented in 'struct X86CPU' with
uint64_t hyperv_features so duplicating them in env->features adds
little (or zero) benefits. THe other half of Hyper-V emulation features
is also stored with values in hyperv_vendor_id[], hyperv_limits[],...
so env->features[] is already incomplete.
Remove Hyper-V feature leaves from env->features[] completely.
kvm_hyperv_properties[] is converted to using raw CPUID func/reg
pairs for features, this allows us to get rid of hv_cpuid_get_fw()

It's very easy to mistakenly extend kvm_default_props to include
features that require a kernel version that's too recent. Add a
comment warning about that, pointing to the documentation file
where the minimum kernel version for KVM is documented.

Hyper-V 2016 refuses to boot on Skylake+ CPU models because they lack
'xsaves'/'vmx-xsaves' features and this diverges from real hardware. The
same issue emerges with AMD "EPYC" CPU model prior to version 3 which got
'xsaves' added. EPYC-Rome/EPYC-Milan CPU models have 'xsaves' enabled from
the very beginning so the comment blaming KVM to explain why other CPUs
lack 'xsaves' is likely outdated.

Per xHCI spec v1.2 chapter 4.17.5 page 296:
If MSI or MSI-X interrupts are enabled, Interrupt Pending (IP)
shall be cleared automatically when the PCI dword write generated
by the interrupt assertion is complete.
Currently QEMU does not clear the IP flag in the MSI / MSI-X mode.
This causes subsequent spurious interrupt to be delivered to guests.
To solve this, we change the xhci intr_raise() hook routine to have
a bool return value that is passed to its caller (the xhci core),
with true indicating that IP should be self-cleared.
Fixes: 62c6ae04cf ("xhci: Initial xHCI implementation")
Fixes: 4c47f80063 ("xhci: add msix support")

At present MSI / MSI-X interrupts are triggered regardless of the
irq level. We should have checked the level to determine whether
the interrupt needs to be delivered.
The level check logic was present in early versions of the xhci
model, but got dropped later by a rework of interrupt handling
under commit 4c4abe7cc9 ("xhci: rework interrupt handling").

Per GitLab documentation [*]:
"rules replaces only/except and they can’t be used together
in the same job."
Since the 'rules' syntax is more powerful and we are already using
it, convert the check-dco/check-patch jobs so no job use the 'only/
except' syntax.
