8168ca8ea3 tests/qapi-schema: Avoid 'str' in alternate test cases
The next commit is going to make alternate members of type 'str'
conflict with other scalar types.  Would break a few test cases that
don't actually require 'str'.  Flip them from 'str' to 'bool' or
'EnumOne'.

8339fa266c qapi: Document visit_type_any() issues with keyval input
It's already documented in keyval.c (commit 0ee9ae7), but visitor.h
can use a note, too.

5891c388bb qobject-input-visitor: Reject non-finite numbers with keyval
The QObject input visitor can produce only finite numbers when its
input comes out of the JSON parser, because the the JSON parser
implements RFC 7159, which provides no syntax for infinity and NaN.

However, it can produce infinity and NaN when its input comes out of
keyval_parse(), because we parse with strtod() then.

The keyval variant should not be able to express things the JSON
variant can't.  Rejecting non-finite numbers there is the conservative
fix.  It's also minimally invasive.

We could instead extend our JSON dialect to provide for infinity and
NaN.  Not today.

Note that the JSON formatter can emit non-finite numbers (marked FIXME
in commit 6e8e5cb).

 This includes preliminary patches towards fixing migration for Radix

 regressions due to the re-organization of the interrupt controller

03c320d803 block/file-*: *_parse_filename() and colons
The file drivers' *_parse_filename() implementations just strip the
optional protocol prefix off the filename. However, for e.g.
"file:foo:bar", this would lead to "foo:bar" being stored as the BDS's
filename which looks like it should be managed using the "foo" protocol.
This is especially troublesome if you then try to resolve a backing
filename based on "foo:bar".

This issue can only occur if the stripped part is a relative filename
("file:/foo:bar" will be shortened to "/foo:bar" and having a slash
before the first colon means that "/foo" is not recognized as a protocol
part). Therefore, we can easily fix it by prepending "./" to such
filenames.

Before this patch:
$ ./qemu-img create -f qcow2 backing.qcow2 64M
Formatting 'backing.qcow2', fmt=qcow2 size=67108864 encryption=off
    cluster_size=65536 lazy_refcounts=off refcount_bits=16

0d54a6fed3 block: Fix backing paths for filenames with colons
path_combine() naturally tries to preserve a protocol prefix. However,
it recognizes such a prefix by scanning for the first colon; which is
different from what path_has_protocol() does: There only is a protocol
prefix if there is a colon before the first slash.

A protocol prefix that is not recognized by path_has_protocol() is none,
and should thus not be taken as one.

Case in point, before this patch:
$ ./qemu-img create -f qcow2 -b backing.qcow2 ./top:image.qcow2
qemu-img: ./top:image.qcow2: Could not open './top:backing.qcow2':
    No such file or directory

Afterwards:
$ ./qemu-img create -f qcow2 -b backing.qcow2 ./top:image.qcow2
qemu-img: ./top:image.qcow2: Could not open './backing.qcow2':
    No such file or directory

bcb07dba92 block: Tweak error message related to qemu-img amend
When converting a 1.1 image down to 0.10, qemu-iotests 060 forces
a contrived failure where allocating a cluster used to replace a
zero cluster reads unaligned data.  Since it is a zero cluster
rather than a data cluster being converted, changing the error
message to match our earlier change in 'qcow2: Make distinction
between zero cluster types obvious' is worthwhile.

29cf933635 qemu-img: copy *key-secret opts when opening newly created files
The qemu-img dd/convert commands will create an image file and
then try to open it. Historically it has been possible to open
new files without passing any options. With encrypted files
though, the *key-secret options are mandatory, so we need to
provide those options when opening the newly created file.

305b4c60f2 qemu-img: introduce --target-image-opts for 'convert' command
The '--image-opts' flag indicates whether the source filename
includes options. The target filename has to remain in the
plain filename format though, since it needs to be passed to
bdrv_create().  When using --skip-create though, it would be
possible to use image-opts syntax. This adds --target-image-opts
to indicate that the target filename includes options. Currently
this mandates use of the --skip-create flag too.

The --image-opts flag can only be used to affect the parsing

the traditional style regardless, since it needs to be passed
to the bdrv_create() API which does not support the new style
opts.

63c8ef2890 mirror: Drop permissions on s->target on completion
This fixes an assertion failure that was triggered by qemu-iotests 129
on some CI host, while the same test case didn't seem to fail on other
hosts.

Essentially the problem is that the blk_unref(s->target) in
mirror_exit() doesn't necessarily mean that the BlockBackend goes away
immediately. It is possible that the job completion was triggered nested
in mirror_drain(), which looks like this:

    BlockBackend *target = s->target;
    blk_ref(target);
    blk_drain(target);
    blk_unref(target);

In this case, the write permissions for s->target are retained until
after blk_drain(), which makes removing mirror_top_bs fail for the
active commit case (can't have a writable backing file in the chain
without the filter driver).

Explicitly dropping the permissions first means that the additional
reference doesn't hurt and the job can complete successfully even if
called from the nested blk_drain().

ede24a0264 pc: ACPI BIOS: use highest NUMA node for hotplug mem hole SRAT entry
For reasons unknown, Windows won't online all memory, both at command
line and hot-plugged later, unless the hotplug mem hole SRAT entry
specifies a node greater than or equal to the ones where memory is
added.

Using the highest node on the machine makes recent versions of Windows
happy.

With this example command line:
  ... \
  -m 1024,slots=4,maxmem=32G \
  -numa node,nodeid=0 \
  -numa node,nodeid=1 \
  -numa node,nodeid=2 \
  -numa node,nodeid=3 \
  -object memory-backend-ram,size=1G,id=mem-mem1 \
  -device pc-dimm,id=dimm-mem1,memdev=mem-mem1,node=1

Windows reports a total of 1G of RAM without this commit and the expected
2G with this commit.

a896f7f26a nvme: Add support for Controller Memory Buffers
Implement NVMe Controller Memory Buffers (CMBs) which were added in
version 1.2 of the NVMe Specification. This patch adds an optional
argument (cmb_size_mb) which indicates the size of the CMB (in
MB). Currently only the Submission Queue Support (SQS) is enabled
which aligns with the current Linux driver for NVMe.

0bb0aea4ba qemu-iotests: Test streaming with missing job ID
This adds a small test for the image streaming error path for failing
block_job_create(), which would have found the null pointer dereference

525989a50a stream: fix crash in stream_start() when block_job_create() fails
The code that tries to reopen a BlockDriverState in stream_start()
when the creation of a new block job fails crashes because it attempts
to dereference a pointer that is known to be NULL.

This is a regression introduced in a170a91fd3,
likely because the code was copied from stream_complete().

3cf7daf8c3 vhost-user: pass message as a pointer to process_message_reply()
process_message_reply() was recently updated to get full message
content instead of only its request field.

There is no need to copy all the struct content into the stack,
so just pass its pointer as const.

75ebec11af virtio_net: Bypass backends for MTU feature negotiation
This patch adds a new internal "x-mtu-bypass-backend" property
to bypass backends for MTU feature negotiation.

When this property is set, the MTU feature is negotiated as soon
as supported by the guest and a MTU value is set via the host_mtu
parameter. In case the backend advertises the feature (e.g. DPDK's
vhost-user backend), the feature negotiation is propagated down to
the backend.

When this property is not set, the backend has to support the MTU
feature for its negotiation to succeed.

For compatibility purpose, this property is disabled for machine
types v2.9 and older.

f80c98740e intel_iommu: allow dev-iotlb context entry conditionally
When device-iotlb is not specified, we should fail this check. A new
function vtd_ce_type_check() is introduced.

While I'm at it, clean up the vtd_dev_to_context_entry() a bit - replace
many "else if" usage into direct if check. That'll make the logic more
clear.
