795e9e05c3 virPCIGetVirtualFunctions: Fetch also network interface name if needed
'virNetDevGetVirtualFunctions' calls 'virPCIGetVirtualFunctions' and
then re-iterates the returned list to fetch the interface names for the
returned virtual functions.

If we move the fetching of the interface name into
virPCIGetVirtualFunctions we can simplify the code and remove a bunch of
impossible error states.

To accomplish this the function is renamed to
'virPCIGetVirtualFunctionsFull' while keeping a wrapper with original
name and if the physical port ID is passed the interface name is fetched
too without the need to re-convert the address into a sysfs link.

For now 'virNetDevGetVirtualFunctions' still converts the returned data
into two lists.

fcae7a44c3 nodedev: look up mdevs by UUID and parent
Since UUID is not guaranteed to be unique by mdevctl, we may have more
than one nodedev with the same UUID. Therefore, we need to disambiguate
when looking up mdevs by specifying the UUID and parent address, which
mdevctl guarantees to be a unique combination.

3bd8181bc5 nodedev: Handle inactive mdevs with the same UUID
Unfortunately, mdevctl supports defining more than one mdev with the
same UUID as long as they have different parent devices. (Only one of
these devices can be active at any given time).

This means that we can't use the UUID alone as a way to uniquely
identify mdev node devices. Append the parent address to ensure
uniqueness. For example:

    Before: mdev_88a6b868_46bd_4015_8e5b_26107f82da38
    After:  mdev_88a6b868_46bd_4015_8e5b_26107f82da38_0000_00_02_0

08d29eb3b1 nodedev: add PostParse callback for nodedev parsing
This can be used similarly to other postparse callbacks in libvirt --
filling in additional information that can be determined by using the
information provided in the XML. In this case, we determine the address
of the parent device and cache it in the mdev caps so that we can use it
for generating a unique name and interacting with mdevctl.

e44408dd9c nodedev: cache parent address in mdev caps
mdevctl can report multiple defined devices with the same UUID
but different parents, including parents that don't actually exist on
the host machine. Libvirt sets the parent to the 'computer' device for
all of the mdevs that have nonexistent parents. Because of this, it's
possible that there are multiple devices with the same UUID and the same
'computer' device as their parent, so the combination of uuid and parent
nodedev name is not guaranteed to be a unique name.

We need to ensure that each nodedev has a unique name. If we can't use
the UUID as a unique nodedev name, and we can't use the combination of
UUID and nodedev parent name, we need to find another solution. By
caching and using the parent name reported by mdevctl in combination
with the UUID, we can achieve a unique name. mdevctl guarantees that its
uuid/parent combination is unique.

This value will be used to set the mdev nodedev name in a following commit.

a9c1febcf4 nodedev: fix xml output for mdev parents in test suite
Commit 51fbbfdce8 attempted to get the proper nodedev name for the
parent of an defined mdev by traversing the filesystem and looking for a
device that had the appropriate sysfs path.  This works, but it would be
cleaner to to avoid mucking around in the filesystem and instead just
just examine the list of devices we have in memory.

We already had a function nodeDeviceFindAddressByName() which constructs
an address for parent device in a format that can be used with mdevctl.
So if we refactor this function into a a function that simply formats an
address for an arbitrary virNodeDeviceObj*, then we can use this
function as a predicate for our new virNodeDeviceObjListFind() function
from the previous commit. This will search our list of devices for one
whose address matches the address we get from mdevctl.

One nice benefit of this approach is that our test cases will now
display xml output with the proper parent name for mdevs (assuming that
we've added the appropriate mock parent devices to the test driver).
Previously they just displayed 'computer' for the parent because the
alternative would have required specially constructing a mock filesystem
environment with a sysfs that mapped to the appropriate parent.

5df2c49263 util: directly query KVM for TSC scaling support
We currently query the host MSRs to determine if TSC scaling is
supported. This works OK when running privileged and can open
the /dev/cpu/0/msr. When unprivileged we fallback to querying
MSRs from /dev/kvm. This is incorrect because /dev/kvm only
reports accurate info for MSRs that are valid to use from inside
a guest.  The TSC scaling support MSR is not, thus we always end
up reporting lack of TSC scaling when unprivileged.

The solution to this is easy, because KVM can directly report
whether TSC scaling is available, which matches what QEMU will
do at startup.

a29af66ffe Revert "remote: remove probing logic from virtproxyd dispatcher"
This reverts commit 05bd8db60b.

It is true that the remote driver client now contains logic for probing
the driver to connect to when using modular daemons. This logic, however,
only runs when the remote driver is NOT running inside a daemon since we
don't want it activated inside libvirtd. Since the same remote driver
build is used in all daemons, we can't rely on it in virtproxyd either.
Thus we need to keep the virtproxyd probing logic

a2476f37a7 virSetUIDGIDWithCaps: Set bounding capabilities only with CAP_SETPCAP
In one of my previous patches I've tried to postpone dropping
CAP_SETPCAP until the very end because it's needed for
capng_apply(). What I did not realize back then was that we might
not have the capability to begin with. Because of unknown reasons
capng_apply() pollutes logs only for CAPNG_SELECT_BOUNDS and not
for CAPNG_SELECT_CAPS.

Reproducer is really simple: run libvirtd as a regular user.
During its initialization, libvirtd will spawn some binaries
(dnsmasq, qemu-*, etc.) and while doing so it will try to drop
capabilities.

Anyway, let's call capng_apply(CAPNG_SELECT_BOUNDS) only if we
have the CAP_SETPCAP (which is tracked in need_setpcap variable).

wrapped in one layer of parenthesis more than needed.

a556615555 src: workaround warning triggered in glib 2.69
Libvirt is using the G_GNUC_FALLTHROUGH macro provided by glib since
version 2.60. Since we need to support older glib, we also have some
compatibility code to define it if missing.

We set the GLIB_VERSION_MAX_ALLOWED macro to ensure we get warnings
when we use an API that dates from a glib version newer than our
minimum benchmark. Historically this didn't get enforced for (most)
macros, but GLib 2.69 has addressed that gap.

This causes our usage of G_GNUC_FALLTHROUGH to trigger warnings.
GLib is right to warn, because it does not know that we have added
our own fallback for older versions.

The only way to squelch this warning though, is to fully undefine
the GLib provided G_GNUC_FALLTHROUGH and use our own in its place.
We'll be able to remove all this compat burden when we finally
update the min glib version to be >= 2.60

e286a62941 qemu: process: Extract code for submitting event handling to separate thread

extracting the code into a helper named 'qemuProcessEventSubmit' and
reuse it where appropriate.
