c7ceac59f3 tests: Refresh valgrind suppressions
Since nobody is expected to run valgrind over scripts now, we can
drop plenty of suppressions. Also, there are some old ones that
no longer exist and new ones, that are not covered.

7ba20863a7 meson: Annotate each test() with 'suite'
A test case can be part of a test suite (just like we already
have 'syntax-check'). This then allows developers to run only a
subset of tests. For instance - when using valgrind test setup
(`meson test -C _build/ --setup valgrind`) it makes zero sense to
run syntax-check tests or other script based tests (e.g.
check-augeas-*, check-remote_protocol, etc.). What does makes
sense is to run compiled binaries.

Strictly speaking, reaching that goal is as trivial as annotating
only those compiled tests (declared in tests/meson.build) and
running them selectively:

  meson test -C _build/ --setup valgrind --suite $TAG

But it may be also desirable to run test scripts separately.

Therefore, introduce two new tags: 'bin' for compiled tests, and
'script' for script based tests and annotate each test()
accordingly.

988f8443fb qemu: require memfd memory for virtio 'blob' support
The virtio-gpu 'blob' support was insufficiently validated. Qemu
requires a memfd memory backing in order to use udmabuf and enable blob
support. Example error:

    error: Failed to start domain 'rhel9'
    error: internal error: qemu unexpectedly closed the monitor: 2023-07-18T02:33:57.083178Z qemu-kvm: -device {"driver":"virtio-vga","id":"video0","max_outputs":1,"blob":true,"bus":"pcie.0","addr":"0x1"}: cannot enable blob resources without udmabuf

ecbce92371 qemu: Adapt to new way of specifying PC speaker
Historically, the way to set PC speaker for a guest was to pass:

  -soundhw pcspk

but as of QEMU commit v5.1.0-rc0~28^2~3 this is deprecated and we
should use:

  -machine pcspk-audiodev=$id

instead. The old way was then removed in commit v7.1.0-rc0~99^2~3.

Now, ideally we would have a capability selecting whether we talk
to a QEMU that understands the new way or not. But it's not that
simple - the machine attribute is just an alias to the .audiodev=
attribute of 'isa-pcspk' object and both are created in
pc_machine_initfn() function, i.e. not then the PC_MACHINE() class
is initialized, but when it's instantiated. IOW, it's not possible
for us to query whether we're dealing with older or newer QEMU.

But given that the newer version is supported since v5.1.0 and the
minimal version we require is v4.2.0 (i.e. there are two releases
which don't understand the newer cmd line) and how frequently this
feature is (un-)used (the issue was reported after ~1 year since it
stopped working), I believe we can live without any capability and
just use the newer cmd line unconditionally.

When this option is enabled (default=false), then it will no longer

discard to the lower layer.

677156f662 conf: Introduce <address/> for virtio-mem and virtio-pmem
Both virtio-mem and virtio-pmem devices have '.memaddr' attribute
which controls the address where they are mapped in the guest
memory. Ideally, users do not need to specify this as QEMU does
the right thing and computes addresses automatically on startup.

But soon, we will need to record this address as it is part of
guest ABI. And also, there might be some users that want to
control this value. Now, we are in a bit of a pickle, because
both these device types already have a PCI address, therefore we
can't just use <address/> blindly. But what we can do, is
introduce <address/> under the <target/> element. This is also
more conceptual, as knobs under <target/> control guest visible
config of memory device (and .memaddr surely falls into that
category).

NB, SgxEPCDeviceInfo struct in QMP definition also has .memaddr
attribute, but because of the way we build cmd line there's no
(easy) way to set the attribute. So ignore that for now.

a091edf9db virmockstathelpers: Adapt to musl-1.2.4
With musl-1.2.3: I get the following macros defined (from
$builddir/meson-config.h):

  #define WITH_LSTAT 1
  #define WITH_LSTAT64 1
  #define WITH_LSTAT_DECL 1
  #define WITH_STAT 1
  #define WITH_STAT64 1
  #define WITH_STAT_DECL 1
  #define WITH___LXSTAT 1
  #define WITH___LXSTAT64 1
  #define WITH___XSTAT 1
  #define WITH___XSTAT64 1

which in turn means the virmockstathelpers.c ends up defining:

  MOCK_STAT64
  MOCK_LSTAT64

But with  musl-1.2.4 everything changes and the set of defined
macros gets simplified to:

  #define WITH_LSTAT 1
  #define WITH_LSTAT_DECL 1
  #define WITH_STAT 1
  #define WITH_STAT_DECL 1
  #define WITH___LXSTAT 1
  #define WITH___XSTAT 1

which results in no MOCK_* macros defined in
virmockstathelpers.c, i.e. no stat() mocking, nada. The reason
for this simplification are these musl commits [1][2] which
removed all 64 bit aliases. And that's not what our logic for
deciding what flavor of stat() to mock counted with.

Nevertheless, we do build with Alpine Linux in our CI, so how
come we don't see this problem there? Well, simply because Alpine
Linux maintainers decided to revert the commits [3][4]. But on
distributions that use vanilla musl, this problem can be seen
easily.

fea0d8c40d qemu: Move <hostdev> SCSI path generation into qemuDomainPrepareHostdev()
When preparing a SCSI <hostdev/> with passthrough of a host SCSI
adapter (i.e. no protocol), a virStorageSource structure is
initialized and stored inside virDomainHostdevDef. But the source
structure is filled in many places, with almost the same code.

Firstly, qemuProcessPrepareHostHostdev() and
qemuConnectDomainXMLToNativePrepareHostHostdev() are the same.

Secondly, qemuDomainPrepareHostdev() allocates the src structure,
only to let qemuProcessPrepareHostHostdev() fill src->path later.

Well, src->path can be filled at the same place where the src
structure is allocated (qemuDomainPrepareHostdev()) which renders
the other two functions needless.

The qemuxml2argvtest does a bit of 'fixups' to parsed
virDomainDef just before generating the cmd line. For instance,
it sets PCI backend for hostdevs (to VFIO). The reason for this
is that we want to make the test host independent and thus
letting the code chose backend at runtime might render different
results on different machines. But this is not necessary, as
virpcimock (that the test uses) already creates a fake, but
stable environment (where /dev/vfio/vfio and IOMMU groups exist),
thus qemuHostdevHostSupportsPassthroughVFIO() returns true,
regardless of the actual host support.

5670c50ffb qemu_domain: Increase memlock limit for NVMe disks
When starting QEMU, or when hotplugging a PCI device QEMU might
lock some memory. How much? Well, that's an undecidable problem.

But despite that, we try to guess. And it more or less works,
until there's a counter example. This time, it's a guest with
both <hostdev/> and an NVMe <disk/>. I've started a simple guest
with 4GiB of memory:

  # virsh dominfo fedora
  Max memory:     4194304 KiB
  Used memory:    4194304 KiB

And here are the amounts of memory that QEMU tried to lock,
obtained via:

  grep VmLck /proc/$(pgrep qemu-kvm)/status

  1) with just one <hostdev/>
     VmLck:   4194308 kB

  2) with just one NVMe <disk/>
     VmLck:   4328544 kB

  3) with one <hostdev/> and one NVMe <disk/>
     VmLck:   8522852 kB

Now, what's surprising is case 2) where the locked memory exceeds
the VM memory. It almost resembles VDPA. Therefore, treat is as
such.

Unfortunately, I don't have a box with two or more spare NVMe-s
so I can't tell for sure. But setting limit too tight means QEMU
refuses to start.

This will simplify using QMP command validation in other tests which
will use testQemuGetRealCaps.

'testutilsqemuschema' module is now linked into 'test_utils_qemu' as it
contains no monitor-specific code itself and after this patch it's
referenced directly from that module.

There are couple of g_dbus_*() functions we provide an

these functions are declared in gio/gdbusconnection.h as:

  GIO_AVAILABLE_IN_ALL
  GDBusConnection  *g_bus_get_sync (GBusType            bus_type,
                                    GCancellable       *cancellable,
                                    GError            **error);

where GIO_AVAILABLE_IN_ALL is declared as (in
/gio/gio-visibility.h):

  #if (defined(_WIN32) || defined(__CYGWIN__)) && !defined(GIO_STATIC_COMPILATION)
  #  define _GIO_EXPORT __declspec(dllexport)
  #  define _GIO_IMPORT __declspec(dllimport)
  #elif __GNUC__ >= 4
  #  define _GIO_EXPORT __attribute__((visibility("default")))
  #  define _GIO_IMPORT
  #else
  #  define _GIO_EXPORT
  #  define _GIO_IMPORT
  #endif
  #ifdef GIO_COMPILATION
  #  define _GIO_API _GIO_EXPORT
  #else
  #  define _GIO_API _GIO_IMPORT
  #endif

  #define _GIO_EXTERN _GIO_API extern

  #define GIO_AVAILABLE_IN_ALL _GIO_EXTERN

Now, on mingw the functions we mock are declared with dllimport
attribute which makes the compiler unhappy:

  ../tests/virgdbusmock.c:25:24: error: 'g_bus_get_sync'
  redeclared without dllimport attribute: previous dllimport
  ignored [-Werror=attributes]

The solution is to do what glib does when it compiles the gio
module: set GIO_COMPILATION macro which in turn annotates the
function with dllexport attribute.

24ad99d76d qemu: Automatically add firmware type/features information
Even when the user is not taking advantage of firmware
autoselection and instead manually providing all the necessary
information, in most cases they're still going to use firmware
builds that are provided by the OS vendor, are installed in
standard paths and come with a corresponding firmware
descriptor.

Similarly, even when the user is not guiding the autoselection
process by specifying the desired status of certain features
and instead is relying on the system-level descriptor priority
being set up correctly, libvirt will still ultimately decide to
use a specific descriptor, which includes information about the
firmware's features.

In both these cases, take the additional information that were
obtained from the firmware descriptor and reflect them back into
the domain XML, where they can be conveniently inspected by the
user and management applications alike.

50d68c1d10 qemu: Don't drop firmware type/features information
Now that we no longer reject configurations that include both
this information and explicit firmware details, as long of
course as everything is internally consistent, and that we've
ensured that we produce maximally compatible XML on migration,
we can stop stripping this information at the end of the
firmware selection process.

There are several advantages to keeping this information around:

  * if the user wants to change the firmware configuration for
    an existing VM, they can simply drop the <loader> and
    <nvram> elements, tweak the firmware autoselection parameters
    and let libvirt pick a firmware that matches on the new
    requirements;

  * management applications can inspect the XML and easily
    figure out firmware-related information without having to
    reverse-engineer them based on some opaque paths.

Overall, this change makes things more transparent and easier to
understand. The improvement is so significant that, in a
follow-up commit, we're going to ensure that this information is
available in even more cases.

ccf4aa37a0 conf: Remove some firmware validation checks
libvirt 8.6.0 introduced these checks and very clearly delineated
two possible firmware selection scenarios: manual firmware
selection, where the user is responsible for providing all
information, and firmware autoselection, where a list of desired
features is provided and everything else is handled by libvirt.

In the interest of maintaining the clear separation between these
two scenarios, setting most attributes when firmware autoselection
is active will result in the configuration being rejected.

This works fine, but is unnecessarily restrictive: in most cases,
the additional information that the user has provided matches
the information that libvirt would have discovered on its own by
looking at firmware descriptors, and asking the user to scrub it
from the XML only result in pointless friction.

Remove these checks entirely.

Unsurprisingly, this results in a few test cases that were
rejected until now to suddenly start working and producing
sensible results.

The firmware-auto-efi-loader-path-nonstandard test case is
notable: while we can now enable the xml2xml part of the test,
the xml2argv part is still failing, although in a slightly
different way. This is expected: since the firmware binary is a
non-standard one, libvirt is unable to figure out the missing
information from a firmware descriptor, and the configuration
is still ultimately an invalid one. However, if we were to find
such a configuration on disk at daemon startup, we would not
ignore it completely and instead would offer the user a chance
to fix it.

3030010fa9 tests: Fix firmware descriptor masking test
Right now we're checking that firmware descriptor masking works

However, that firmware descriptors contains the details for a
perfectly valid and quite common situation: Secure Boot being
supported by the firmware build, but being effectively disabled
by the lack of certificates in the NVRAM template.

Unmask that firmware descriptor, and instead create a dummy one
that has higher priority than all other OVMF builds and points
to paths that are obviously incorrect, which should make it
easy to notice it getting accidentally unmasked in the future.

77c9663d72 qemu: add support for librbd layered encryption
This commit enables libvirt users to use layered encryption
of RBD images, using the librbd encryption engine.
This allows opening of an encrypted cloned image
whose parent is encrypted with a possibly different encryption key.
To open such images, multiple encryption secrets are expected
to be defined under the encryption XML tag.

df2ef2e706 qemuBuildThreadContextProps: Prune .node-affinity wrt <emulatorpin/>
When a thread-context object is specified on the cmd line, then
QEMU spawns a thread and sets its affinity to the list of NUMA
nodes specified in .node-affinity attribute. And this works just
fine, until the main QEMU thread itself is not restricted.

Because of v5.3.0-rc1~18 we restrict the main emulator thread
even before QEMU is executed and thus then it tries to set
affinity of a thread-context thread, it inevitably fails with:

  Setting CPU affinity failed: Invalid argument

Now, we could lift the pinning temporarily, let QEMU spawn all
thread-context threads, and enforce pinning again, but that would
require some form of communication with QEMU (maybe -preconfig?).
But that would still be wrong, because it would circumvent
<emulatorpin/>.

Technically speaking, thread-context is an internal
implementation detail of QEMU, and if it weren't for it, the main
emulator thread would be doing the allocation. Therefore, we
should honor the pinning and prune the list of node so that
inaccessible ones are dropped.

95ae91fdd4 qemuxml2argvmock: Drop virNuma* mocks
Since qemuxml2argvtest is now using virnumamock, there's no need
for qemuxml2argvmock to offer reimplementation of virNuma*()
functions. Also, the comment about CLang and FreeBSD (introduced
in v4.3.0-40-g77ac204d14) is no longer true. Looks like noinline
attribute was the missing culprit.

c4c90063a5 qemuxml2argvdata: Extend vCPUs placement in memory-hotplug-dimm-addr.xml
So far, the memory-hotplug-dimm-addr.xml test case pins its vCPUs
onto CPUs 0-1 which correspond to NUMA node #0 (per
tests/vircaps2xmldata/linux-basic/system/node/node0). Place vCPUs
onto nodes #1 and #2 too so that DIMM <memory/> device can
continue using thread-context after future patches. This
configuration, as-is currently, would make QEMU error out anyway.

We have couple of qemuxml2argvtest cases where up to 8 NUMA nodes
are assumed. These are used to check whether disjoint ranges of
host-nodes= is generated properly. Without prejudice to the
generality, we can rewrite corresponding XML files to use up to 4
NUMA nodes and still have disjoint ranges.

28ec9d86b3 qemuxml2argvtest: Use virnuma mock
While no part of cmd line building process currently depends on a
host NUMA configuration, this will change soon. Use freshly
changed virnumamock from qemuxml2argvtest and make the mock read
NUMA data from vircaps2xmldata which seems to have the most rich
NUMA configuration.

This also means, we have to start building virnumamock
unconditionally. But this is not a problem, since nothing inside
of the mock relies on Linux specificity. The whole mock is merely
just reading files and parsing them.
