Raw local files do not pass through the backing store detector and thus
the code did not allocate the required backing store terminator for
them. Previously the terminating element would be formatted into the XML
since the default values used for the metadata allowed that. This is a
regression since a693fdba01 which was not detected in the review.
This patch also reverts all the changes in the test files.
In status XML, we do not store the QEMU version information, we only
format all the capabilities. We dropped QEMU_CAPS_PCI_MULTIBUS
in commit 5b783379 which was released in libvirt 3.2.0.
Therefore the only way of telling if the already running domain
at the time of daemon restart has been started with a QEMU that does
use 'pci.0' or not on PPC is to look at the pci-root controller's
alias. This is not an option if the domain has a user-specified alias
for the pci-root.
Instead of reintroducing the capability, assume 'pci.0' when we have
no version information. That way the only left broken use case would
be the combination of user aliases and very old QEMU.
Partially reverts commit 3a37af1e4.

We do not fill out qemuCaps->arch when parsing status XML.
Use def->os.arch like we do for PPC.
This fixes hotplug after daemon restart for domains that use
a user alias for the implicit pci-root on x86.

This patch modifies some not yet used test data so that the adding a test using
this data is a clean patch and not an addition of huge file with some
adjustments in small files that will be hidden in the middle of that commit.
These changes include:
- Add system dir in vircaps2xmldata/linux-caches
Back when data for systems with resctrl support were added they had the
/sys/fs/system directory put into a system/ subdir of the test and
/sys/fs/resctrl in a resctrl/ subdir of that test. However, if we also want a
negative test for the resctrl (requesting allocation on a system that does not
support resctrl), we need one a test case with any sensible (with cache info)
system/ subdir and no resctrl/ one. Easiest way is to add a
system -> . symlink into existing test case.
- Change default group schemata for linux-resctrl and linux-resctrl-cdp
That way we can fit some allocation in.
- Remove one cache from resctrl-skx's schemata and make some room for
allocations
That system already has only one cache, so that file was wrong anyway. We
have a version with 2 caches already (linux-resctrl-skx-twocaches), so this
will also add variety to future tests.
- Add some empty allocation for resctrl-skx
Just to have slightly more coverage and variety. We can be sure nothing bad
happens if such allocation exists in case we have that in the tests.

Libvirt historically stores storage source path including the volume as
one string in the XML, but that is not really flexible enough when
dealing with the fields in the code. Previously we'd store the slash
separating the two as part of the image name. This was fine for gluster
but it's not necessary and does not scale well when converting other
protocols.
Don't store the slash as part of the path. The resulting change from
absolute to relative path within the gluster driver should be okay,
as the root directory is the default when accessing gluster.
Original implementation used 'SocketAddress' equivalent from qemu for
the disk server field, while qemu documentation specifies
'InetSocketAddress'. The backing store parser uses the correct parsing
function but the formatter used the incorrect one (and also with the
legacy mode enabled which was wrong).
Right-aligning backslashes when defining macros or using complex
commands in Makefiles looks cute, but as soon as any changes is
required to the code you end up with either distractingly broken
alignment or unnecessarily big diffs where most of the changes
are just pushing all backslashes a few characters to one side.

Since we've allowed the <auth> to be a child of <disk>, we'll need
to keep track of how it was read so that when writing out we'll know
whether to format as child of <disk> or <source>. For the argv2xml
parsing, let's format under <source> as a preference. Do not allow
<auth> to be both a child of <disk> and <source>.
Modify the qemuxml2argvtest to add a parse failure when there is an
<auth> as a child of <disk> *and* an <auth> as a child of <source>.
Add tests to validate that if the <auth> was found in <source>, then
the resulting xml2xml and xml2arg works just fine. The two new .args
file are exact copies of the non "-source" version of the file.
The virschematest will read the new test files and validate from a
RNG viewpoint things are fine
Update the virstoragefile, virstoragetest, and args2xml file to show
the "preference" to place <auth> as a child of <source>.
This will be used later on in implementation of new API
virDomainSetLifecycleAction(). In order to use it, we need to store
the value in status XML to not lose the information if libvirtd is
restarted.
If some guest was started by old libvirt where it was not possible
to change the lifecycle action for running guest, we can safely
detect it based on the current actions from the status XML.

Without the fix in the previous patch the JSON data from QEMU would be
interpreted as Haswell-noTSX because x86DataFilterTSX would filter rtm
and hle features as a result of
family == 6 && model == 63 && stepping < 4
test even though this CPU has stepping == 4.

When migration fails, QEMU may provide a description of the error in
the reply to query-migrate QMP command. We can fetch this error and use
it instead of the generic "unexpectedly failed" message.

Express a properly terminated backing chain by putting a
virStorageSource of type VIR_STORAGE_TYPE_NONE in the chain. The newly
used helpers simplify this greatly.
The change fixes a bug as formatting an incomplete backing chain and
parsing it back would end up in expressing a terminated chain since
src->backingStoreRaw was not populated. By relying on the terminator
object this can be now processed appropriately.
Add helpers that will simplify checking if a backing file is valid or
whether it has backing store. The helper virStorageSourceIsBacking
returns true if the given virStorageSource is a valid backing store
member. virStorageSourceHasBacking returns true if the virStorageSource
has a backing store child.
Adding these functions creates a central points for further refactors.
Existing qemuParseCommandLineMem() will parse "-m 4G" format string.
This patch allows it to parse "-m size=8126464k,slots=32,maxmem=33554432k"
format along with existing format. And adds a testcase to validate the changes.

The default_tls_x509_verify (and related) parameters in qemu.conf
control whether the QEMU TLS servers request & verify certificates
from clients. This works as a simple access control system for
servers by requiring the CA to issue certs to permitted clients.
This use of client certificates is disabled by default, since it
requires extra work to issue client certificates.
Unfortunately the code was using this configuration parameter when
setting up both TLS clients and servers in QEMU. The result was that
TLS clients for character devices and disk devices had verification
turned off, meaning they would ignore errors while validating the
server certificate.
This allows for trivial MITM attacks between client and server,
as any certificate returned by the attacker will be accepted by
the client.
This is assigned CVE-2017-1000256 / LSN-2017-0002
