a44f4f3726 rpm: remove with_bash_completion condition
The %meson macro sets "--auto-features=enabled", thus any feature in the
RPM which has a "with_XXX" condition, needs to explicitly pass a
"-DXXX=state" arg to %meson to override the auto features setting.

The with_bash_completion condition is always set to 1, so rather than
adding an arg to %meson, just remove the condition.

b87cfc957f qemu: capabilities: Disable detection of QEMU_CAPS_BLOCK_EXPORT_ADD
We use the capability to switch to using 'block-export-add' in the
upcoming qemu release instead of the at the same time deprecated
'nbd-server-add'.

Unfortunately qemu wants to change the interface of 'block-export-add'
before the release. Since we've tried to stay up to date and added the
code before it was written in stone, we need to disable the use of the
new interface for the upcoming libvirt release so that we don't have a
version of libvirt which would not work with the upcoming qemu version.

Remove the detection of 'block-export-add' until we are more sure how
the qemu interface will look.

This patch partially reverts commit adb9f7123a

1f807631f4 util: Avoid double free in virProcessSetAffinity
The cpu mask was free()'d immediately on any error and at the end of the
function, where it was expected that it would either error out and return or
goto another allocation if the code was to fail.  However since commit
9514e24984 the error path did not return in one new case which caused
double-free in such situation.  In order to make the code more straightforward
just free the mask after it's been used even before checking the return code of
the call.

99a1cfc438 qemu: honour fatal errors dealing with qemu slirp helper
Currently all errors from qemuInterfacePrepareSlirp() are completely
ignored by the callers. The intention is that missing qemu-slirp binary
should cause the caller to fallback to the built-in slirp impl.

Many of the possible errors though should indeed be considered fatal.

ae23a87d85 Revert "spec: Simplify setting features off by default"
As it turns out, the rather complicated structure that is
currently used for enabling or disabling features in the libvirt
build does not cleanly map well to RPM's bcond feature.

Consequently, we need these back in order to support trivially
activating these features through extra macros as build inputs.

This reverts commit 31d687a321.

67e4c24ba1 qemu_migration: Don't mangle NBD part of migration cookie
In recent commit v6.8.0-135-g518be41aaa the formatting of NBD
into migration cookie was moved into a separate function and with
it it was switched from direct printing into the output buffer to
virXMLFormatElement(). But there was a typo. The
virXMLFormatElement() accepts two buffers on input, one for
element attributes and another for child elements. Well, the line
that was supposed to add NBD port into the attributes buffer
printed the attribute directly into the output buffer which
produced this mangled XML:

<qemu-migration>
   port='49153'<nbd>
    <disk target='vda' capacity='8589934592'/>
    <disk target='vdb' capacity='12746752000'/>
  </nbd>
</qemu-migration>

Changing the incriminated line to print into the attributes
buffer fixes the problem.

was introduced that tracks whether the NBD server was started so
that we don't start it twice nor record in the port in the port
allocator twice. Well, this idea is good, but in the
implementation the boolean is never set, so we are reserving the
port twice and would be starting the NBD server twice too if it
wasn't for port reservation fail.

53aec799fa Include vdpa devices in node device list
The current udev node device driver ignores all events related to vdpa
devices. Since libvirt now supports vDPA network devices, include these
devices in the device list.

Example output:

virsh # nodedev-list
[...ommitted long list of nodedevs...]
vdpa_vdpa0

virsh # nodedev-dumpxml vdpa_vdpa0
<device>
  <name>vdpa_vdpa0</name>
  <path>/sys/devices/vdpa0</path>
  <parent>computer</parent>
  <driver>
    <name>vhost_vdpa</name>
  </driver>
  <capability type='vdpa'>
    <chardev>/dev/vhost-vdpa-0</chardev>
  </capability>
</device>

NOTE: normally the 'parent' would be a PCI device instead of 'computer',
but this example output is from the vdpa_sim kernel module, so it
doesn't have a normal parent device.

7555a55470 qemu: implement memory failure event
Since QEMU 5.2 (commit-77b285f7f6), QEMU supports 'memory failure'
event, posts event to monitor if hitting a hardware memory error.
Fully support this feature for QEMU.

Test with commit 'libvirt: support memory failure event', build a
little complex environment(nested KVM):
1, install newly built libvirt in L1, and start a L2 vm. run command
in L1:
 ~# virsh event l2 --event memory-failure

2, run command in L0 to inject MCE to L1:
 ~# virsh qemu-monitor-command l1 --hmp mce 0 9 0xbd000000000000c0 0xd 0x62000000 0x8c

Test result in l1(recipient hypervisor case):
event 'memory-failure' for domain l2:
recipient: hypervisor
action: ignore
flags:
        action required: 0
        recursive: 0

Test result in l1(recipient guest case):
event 'memory-failure' for domain l2:
recipient: guest
action: inject
flags:
        action required: 0
        recursive: 0

7b1ed1cd73 qemu: stop passing -enable-fips to QEMU >= 5.2.0
Use of the -enable-fips option is being deprecated in QEMU >= 5.2.0. If
FIPS compliance is required, QEMU must be built with libcrypt which will
unconditionally enforce it.

Thus there is no need for libvirt to pass -enable-fips to modern QEMU.
Unfortunately there was never any way to probe for -enable-fips in the
first instance, it was enabled by libvirt based on version number
originally, and then later unconditionally enabled when libvirt dropped
support for older QEMU. Similarly we now use a version number check to
decide when to stop passing -enable-fips.

Note that the qemu-5.2 capabilities are currently from the pre-release
version and will be updated once qemu-5.2 is released.
