Daniel P. Berrangé 7b9645a7d1 util: replace atomic ops impls with g_atomic_int*
Libvirt's original atomic ops impls were largely copied
from GLib's code at the time. The only API difference
was that libvirt's virAtomicIntInc() would return a
value, but g_atomic_int_inc was void. We thus use
g_atomic_int_add(v, 1) instead, though this means
virAtomicIntInc() now returns the original value,
instead of the new value.

This rewrites libvirt's impl in terms of g_atomic_int*
as a short term conversion. The key motivation was to
quickly eliminate use of GNULIB's verify_expr() macro
which is not a direct match for G_STATIC_ASSERT_EXPR.
Long term all the callers should be updated to use
g_atomic_int* directly.

Some UNIX platforms don't declare 'environ' in their

to avoid this problem.

There is no need to do this in the aa-helper code

Jonathon Jongsma 599ae372d8 qemu: don't access vmdef within qemu_agent.c
In order to avoid holding an agent job and a normal job at the same
time, we want to avoid accessing the domain's definition while holding
the agent job. To achieve this, qemuAgentGetFSInfo() only returns the
raw information from the agent query to the caller. The caller can then
release the agent job and then proceed to look up the disk alias from
the vm definition. This necessitates moving a few helper functions to
qemu_driver.c and exposing the agent data structure (qemuAgentFSInfo) in
the header.

In addition, because the agent function no longer returns the looked-up
disk alias, we can't test the alias within qemuagenttest.  Instead we
simply test that we parse and return the raw agent data correctly.

Daniel P. Berrangé 0169f5ecde tests: add host CPU data files for validating die_id
Only Cascadelake-AP CPUs appear to report "die_id" values != 0 on Linux
right now - AMD EPYC's don't report "die_id" (at least with Fedora 31
kernel). Lacking access to Cascadelake-AP CPUs, this test data was from
a Fedora 31 QEMU guest launched with

 -cpu qemu64 -smp sockets=2,dies=3,cores=2,threads=1

Ideally we'd replace this data with some from a real machine reporting
"die_id", to ensure we're not mislead by QEMU's impl.

Daniel P. Berrangé 7b79ee2f78 hostcpu: add support for reporting die_id in NUMA topology
Update the host CPU code to report the die_id in the NUMA topology
capabilities. On systems with multiple dies, this fixes the bug
where CPU cores can't be distinguished:

 <cpus num='12'>
   <cpu id='0' socket_id='0' core_id='0' siblings='0'/>
   <cpu id='1' socket_id='0' core_id='1' siblings='1'/>
   <cpu id='2' socket_id='0' core_id='0' siblings='2'/>
   <cpu id='3' socket_id='0' core_id='1' siblings='3'/>
 </cpus>

Notice how core_id is repeated within the scope of the same socket_id.

It now reports

 <cpus num='12'>
   <cpu id='0' socket_id='0' die_id='0' core_id='0' siblings='0'/>
   <cpu id='1' socket_id='0' die_id='0' core_id='1' siblings='1'/>
   <cpu id='2' socket_id='0' die_id='1' core_id='0' siblings='2'/>
   <cpu id='3' socket_id='0' die_id='1' core_id='1' siblings='3'/>
 </cpus>

So core_id is now unique within a (socket_id, die_id) pair.

Recently CPU hardware vendors have started to support a new structure
inside the CPU package topology known as a "die". Thus the hierarchy
is now:

  sockets > dies > cores > threads

This adds support for "dies" in the XML parser, with the value
defaulting to 1 if not specified for backwards compatibility.

For example a system with 64 logical CPUs might report

   <topology sockets="4" dies="2" cores="4" threads="2"/>

encryption for a disk. The logich which formats it for backing files was
flawed though and didn't format it at all. This worked if the image
became a backing file through the means of a snapshot but not directly.

Force formatting of the source and encryption for any non-disk case to
fix the issue.

This caused problems in many places as we use the formatter to copy the
definition. Effectively any copy lost the secret definition.

Daniel Henrique Barboza 96999404cb Introducing new address type='unassigned' for PCI hostdevs
This patch introduces a new PCI hostdev address type called
'unassigned'. This new type gives users the option to add
PCI hostdevs to the domain XML in an 'unassigned' state, meaning
that the device exists in the domain, is managed by Libvirt
like any regular PCI hostdev, but the guest does not have
access to it.

This adds extra options for managing PCI device binding
inside Libvirt, for example, making all the managed PCI hostdevs
declared in the domain XML to be detached from the host and bind
to the chosen driver and, at the same time, allowing just a
subset of these devices to be usable by the guest.

Next patch will use this new address type in the QEMU driver to
avoid adding unassigned devices to the QEMU launch command line.

Peter Krempa 3615e8b39b util: storage: Don't treat files with missing backing store format as 'raw'
Assuming that the backing image format is raw is wrong when doing image
detection:

1) In -drive mode qemu will still probe the image format of the backing
   image. This means it will try to open a backing file of the image
   which will fail if a more advanced security model is in use.

2) In blockdev mode the image will be opened as raw actually which is
   wrong since it might be qcow. Not opening the backing images will
   also end up in the guest seeing corrupted data.

Rather than attempt to solve various corner cases when us assuming the
storage file being raw and actually being right forbid startup when the
guest image doesn't have the format specified in the metadata.

Michal Privoznik 6edb4321b2 qemu: Allow forcing VFIO when computing memlock limit
With NVMe disks, one can start a blockjob with a NVMe disk
that is not visible in domain XML (at least right away). Usually,
it's fairly easy to override this limitation of
qemuDomainGetMemLockLimitBytes() - for instance for hostdevs we
temporarily add the device to domain def, let the function
calculate the limit and then remove the device. But it's not so
easy with virStorageSourcePtr - in some cases they don't
necessarily are attached to a disk. And even if they are it's
done later in the process and frankly, I find it too complicated
to be able to use the simple trick we use with hostdevs.

Michal Privoznik e1b022890e schemas: Introduce disk type NVMe
There is this class of PCI devices that act like disks: NVMe.
Therefore, they are both PCI devices and disks. While we already
have <hostdev/> (and can assign a NVMe device to a domain
successfully) we don't have disk representation. There are three
problems with PCI assignment in case of a NVMe device:

1) domains with <hostdev/> can't be migrated

2) NVMe device is assigned whole, there's no way to assign only a
   namespace

3) Because hypervisors see <hostdev/> they don't put block layer
   on top of it - users don't get all the fancy features like
   snapshots

NVMe namespaces are way of splitting one continuous NVDIMM memory
into smaller ones, effectively creating smaller NVMe-s (which can
then be partitioned, LVMed, etc.)

Because of all of this the following XML was chosen to model a
NVMe device:

  <disk type='nvme' device='disk'>
    <driver name='qemu' type='raw'/>
    <source type='pci' managed='yes' namespace='1'>
      <address domain='0x0000' bus='0x01' slot='0x00' function='0x0'/>
    </source>

This validation move exposed a flaw in the 'default-video-type' tests

the default video type, which isn't true for those architectures.
This was flying under the radar until now because the SPICE validation

Pavel Mores 73532dadd2 qemu: block: store the delete flag in libvirtd's status XML
Since blockcommit is asynchronous, libvirtd can be restarted while the
operation runs.  To ensure the information necessary to finish up the job
is not lost, serialisation to and deserialisation from the status XML is
added.

To unittest this, the new element was only added to the active commit test,
the non-active commit test doesn't have the new element so as to test its
absence.

Eric Blake 252958ee16 backup: Document new XML for backups
Prepare for new backup APIs by describing the XML that will represent
a backup.  The XML resembles snapshots and checkpoints in being able
to select actions for a set of disks, but has other differences.  It
can support both push model (the hypervisor does the backup directly
into the destination file) and pull model (the hypervisor exposes an
access port for a third party to grab what is necessary).  Add
testsuite coverage for some minimal uses of the XML.

The <disk> element within <domainbackup> tries to model the same
elements as a <disk> under <domain>, but sharing the RNG grammar
proved to be hairy. That is in part because while <domain> use
<source> to describe a host resource in use by the guest, a backup job
is using a host resource that is not visible to the guest: a push
backup action is instead describing a <target> (which ultimately could
be a remote network resource, but for simplicity the RNG just
validates a local file for now), and a pull backup action is instead
describing a temporary local file <scratch> (which probably should not
be a remote resource).  A future refactoring may thus introduce some
way to parameterize RNG to accept <disk type='FOO'>...</disk> so that
the name of the subelement can be <source> for domain, or <target> or
<scratch> as needed for backups. Future patches may improve this area
of code.
