Commit 10c73bf1 fixed a bug that I had introduced back in commit
70249927 - if a vhost-scsi device had no manually assigned PCI
address, one wouldn't be assigned automatically. There was a slight
problem with the logic of the fix though - in the case of domains with
pcie-root (e.g. those with a q35 machinetype),
qemuDomainDeviceCalculatePCIConnectFlags() will attempt to determine
if the host-side PCI device is Express or legacy by examining sysfs
based on the host-side PCI address stored in
hostdev->source.subsys.u.pci.addr, but that part of the union is only
valid for PCI hostdevs, *not* for SCSI hostdevs. So we end up trying
to read sysfs for some probably-non-existent device, which fails, and
the function virPCIDeviceIsPCIExpress() returns failure (-1).
By coincidence, the return value is being examined as a boolean, and
since -1 is true, we still end up assigning the vhost-scsi device to
an Express slot, but that is just by chance (and could fail in the
case that the gibberish in the "hostside PCI address" was the address
of a real device that happened to be legacy PCI).
Since (according to Paolo Bonzini) vhost-scsi devices appear just like
virtio-scsi devices in the guest, they should follow the same rules as
virtio devices when deciding whether they should be placed in an
Express or a legacy slot. That's accomplished in this patch by
returning early with virtioFlags, rather than erroneously using
hostdev->source.subsys.u.pci.addr. It also adds a test case for PCIe
to assure it doesn't get broken in the future.

When I added tests for CPU live update based on disabled/enabled feature

*-{enabled,disabled}.xml data files. Thus any new CPUID bits which are
not present in the original cpuidMap would be ignored. The correct thing

Some ARM platforms, such as the original Raspberry Pi, report the
CPU frequency in the BogoMIPS field of /proc/cpuinfo, so libvirt
parsed that field and returned it through its API.
However, not only many more boards don't report any value there,
but several - including ARMv8-based server hardware, and even the
more recent Raspberry Pi 3 - use this field as originally intended:
to report the BogoMIPS value instead of the CPU frequency.
Since we have no way of detecting how the field is being used,
it's better to report no information at all rather than something
ludicrous like "your shiny 96-core aarch64 virtualization host's
CPUs are running at a whopping 100 MHz".

There is a race between virNetServerProcessClients (main thread) and
remoteDispatchAuthList/remoteDispatchAuthPolkit/remoteSASLFinish (worker
thread) that can lead to decrementing srv->nclients_unauth when it's
zero. Since virNetServerCheckLimits relies on the value
srv->nclients_unauth the underrun causes libvirtd to stop accepting
new connections forever.
Example race scenario (assuming libvirtd is using policykit and the
client is privileged):
1. The client calls the RPC remoteDispatchAuthList =>
remoteDispatchAuthList is executed on a worker thread (Thread
T1). We're assuming now the execution stops for some time before
the line 'virNetServerClientSetAuth(client, 0)'
2. The client closes the connection irregularly. This causes the
event loop to wake up and virNetServerProcessClient to be
called (on the main thread T0). During the
virNetServerProcessClients the srv lock is hold. The condition
virNetServerClientNeedAuth(client) will be checked and as the
authentication is not finished right now
virNetServerTrackCompletedAuthLocked(srv) will be called =>
--srv->nclients_unauth => 0
3. The Thread T1 continues, marks the client as authenticated, and
calls virNetServerTrackCompletedAuthLocked(srv) =>
--srv->nclients_unauth => --0 => wrap around as nclient_unauth is
unsigned
4. virNetServerCheckLimits(srv) will disable the services forever
To fix it, add an auth_pending field to the client struct so that it
is now possible to determine if the authentication process has already
been handled for this client.
Setting the authentication method to none for the client in
virNetServerProcessClients is not a proper way to indicate that the
counter has been decremented, as this would imply that the client is
authenticated.
Additionally, adjust the existing test cases for this new field.

VM drivers may need to store additional private data to the status XML
so that it can be restored after libvirtd restart. Since not everything
is needed add a callback infrastructure, where VM drivers can add only
stuff they need.
Note that the private data is formatted as a <privateData> sub-element
of the <disk> or <backingStore> <source> sub-element. This is done since
storing it out of band (in the VM private data) would require a complex
matching process to allow to put the data into correct place.
Commit id '70249927b' neglected to cover this case because the test
had taken the "shortcut" to already add the <address>; however, when
the PCI address assignment code was adjusted by commit id '70249927'
the vhost-scsi (VIR_DOMAIN_HOSTDEV_SUBSYS_TYPE_SCSI_HOST) wasn't
covered thus returning a 0 for pciFlags. So I altered the tests too
to make sure it doesn't happen again.
Previously the qemuxml2xmloutdata was a softlink to the source
qemuxml2argvdata, so I unlinked and recreated the output file to
force generation of the adddress. Without the test changes, an
address generation returns:
libvirt: Domain Config error : internal error: Cannot automatically
add a new PCI bus for a device with connect flags 00
if an address was supplied in the test, a restart of libvirtd or
edit of a guest would display the following opaque message:

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.

For now it'll just call the virStoragePoolObjUnlock, but a future

Qemu has now an internal mechanism for locking images to fix specific
cases of disk corruption. This requires libvirt to mark the image as
shared so that qemu lifts certain restrictions.

'share-rw' for the disk device configures qemu to allow concurrent
access to the backing storage.
The capability is checked in various supported disk frontend buses since
it does not make sense to partially backport it.
Disk sharing between two VMs may corrupt the images if the format driver
does not support it. Check that the user declared use of a supported
storage format when they want to share the disk.

This capability says if qemu is capable of specifying distances
between NUMA nodes on the command line. Unfortunately, there's no
real way to check this and thus we have to go with version check.
QEMU introduced this in 0f203430dd8 (and friend) which was
released in 2.10.0.

Starting from qemu 2.11, the `-device vmcoreinfo` will create a fw_cfg
entry for a guest to store dump details, necessary to process kernel
dump with KASLR enabled and providing additional kernel details.
In essence, it is similar to -fw_cfg name=etc/vmcoreinfo,file=X but in
this case it is not backed by a file, but collected by QEMU itself.
Since the device is a singleton and shouldn't use additional hardware
resources, it is presented as a <feature> element in the libvirt
domain XML.
The device is arm/x86 only for now (targets that support fw_cfg+dma).

This doesn't add very much value for now, but future test for virresctrl will
take information from vircaps2xmldata (since it is dependent on the same info
then why duplicate it) and this particular use case helps us cover bit more of
the code regarding proper formatting and handling errors. And one more test for
vircaps2xmltest doesn't hurt either.

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.

Since update to glibc-2.26 removed the /usr/include/rpc/rpc.h we used until now,
it showed us a problem with not using XDR_CFLAGS properly. On linux that
variable has usually -I/usr/include/tirpc because we already probe for it
properly, we just don't use it everywhere we need. It is needed by wireshark
dissector as well as testutilsqemu.c (through includes) so the build fails with:
wireshark/src/packet-libvirt.c:33:10: fatal error: rpc/xdr.h: No such file or directory
#include <rpc/xdr.h>
^~~~~~~~~~~
and
In file included from ../src/logging/log_manager.h:29:0,

from testutilsqemu.c:11:
../src/logging/log_protocol.h:9:10: fatal error: rpc/rpc.h: No such file or directory
#include <rpc/rpc.h>

Since lot of tests use testutilsqemu.c it is easier to add XDR_CFLAGS to
AM_CFLAGS than adding it to all $binary_CFLAGS. It's just for tests and we
already have bunch of CFLAGS there anyway.
