[libvirt] [PATCH] Fix spelling for macOS
by Andrea Bolognani
Though it used to be called "Mac OS X" and "OS X" in the past,
it was never "MacOS X" nor "OS-X", and it's just "macOS" now.

[libvirt] [PATCH 00/36] CPU driver enhancements and MSR features
by Jiri Denemark
In addition to usual CPUID bits, some CPU features started to be
reported in IA32_ARCH_CAPABILITIES MSR. This series adds support for
such CPU features.
However, the last patch which actually adds definitions for some MSR
features to the cpu_map should not be pushed yet as the QEMU interface
for MSR features is not complete yet. If a domain with some MSR features
enabled would be started, all of them would be marked as disabled in the
live domain configuration (even though they were actually enabled by
QEMU) and they would disappear during migration.

[libvirt] [PATCH v5 0/2] PPC64 support for NVIDIA V100 GPU with NVLink2 passthrough
by Daniel Henrique Barboza
This series adds support for a new QEMU feature for the spapr
(PPC64) machine, NVIDIA V100 + P9 passthrough. Refer to [1]
for the version 7 of this feature (version accepted upstream).
changes in v5:
- patch1:
* use ARRAY_CARDINALITY instead of hard coding the array size
* fixed leak of 'file' string inside loop
* added ATTRIBUTE_UNUSED in the static function to allow build
to succeed without applying the second patch
- patch 2:
* added QEMU reference of the memory layout of NVLink2 support
* fixed leak of 'pciAddrStr' string inside loop
* added curly braces in multi-line statements
Previous version can be found at [2].

[libvirt] [PATCH] network: only reload firewall after firewalld is finished restarting
by Laine Stump
The network driver used to reload the firewall rules whenever a dbus
NameOwnerChanged message for org.fedoraproject.FirewallD1 was
received. Presumably at some point in the past this was successful at
reloading our rules after a firewalld restart. Recently though I
noticed that once firewalld was restarted, libvirt's logs would get this
message:
The name org.fedoraproject.FirewallD1 was not provided by any .service files
After this point, no networks could be started until libvirtd itself
was restarted.
The problem is that the NameOwnerChanged message is sent twice during
a firewalld restart - once when the old firewalld is stopped, and
again when the new firewalld is started. If we try to reload at the
point the old firewalld is stopped, none of the firewalld dbus calls
will succeed.
The solution is to check the new_owner field of the message - we
should reload our firewall rules only if new_owner is non-empty (it is
set to "" when firewalld is stopped, and some sort of epoch number
when it is again started).

[libvirt] [PATCH] network: clear cached error if we successfully create firewall chains
by Daniel P. Berrangé
Since:
commit 9f4e35dc73ec9e940aa61bc7c140c2b800218ef3
Author: Daniel P. Berrangé <berrange(a)redhat.com>
Date: Mon Mar 18 17:31:21 2019 +0000
network: improve error report when firewall chain creation fails
We cache an error when failing to create the top level firewall chains.
This commit failed to account for fact that we may invoke
networkPreReloadFirewallRules() many times while libvirtd is running.
For example when firewalld is restarted.
When this happens the original failure may no longer occurr and we'll
successfully create our top level chains. We failed to clear the cached
error resulting in us failing to start virtual networks.

[libvirt] [PATCH] qemu: Label uniqDir when probing capabilities
by Martin Kletzander
This does not cause a problem in usual scenarios thanks to us allowing
CAP_DAC_OVERRIDE for the qemu process, however in some scenarios this might be
an issue because the directory is created with mkdtemp(3) which explicitly
creates that with 0700 permissions and qemu running as non-root cannot access
that.
The scenarios include:
- Builds without CAPNG
- Running libvirtd in a container [1]
- and possibly others.
