[PATCH] network: allow for forward dev to be a transient interface
by Laine Stump
A user reported that if they set <forward mode='nat|route' dev='blah'>
starting the network would fail if the device 'blah' didn't already
exist.
This is caused by using "iif" and "oif" in nftables rules to check for
the forwarding device - these two commands work by saving the named
interface's ifindex (an unsigned integer) when the rule is added, and
comparing it to the ifindex associated with the packet's path at
runtime. This works great if the interface both 1) exists when the
rule is added, and 2) is never deleted and re-created after the rule
is added (since it would end up with a different ifindex).
When checking for the network's bridge device, it is okay for us to
use "iif" and "oif", because the bridge device is created before the
firewall rules are added, and will continue to exist until just after
the firewall rules are deleted when the network is shutdown.
But since the forward device might be deleted/re-added during the
lifetime of the network's firewall rules, we must instead us "oifname"
and "iifname" - these are much less efficient than "Xif" because they
do a string compare of the interface's name rather than just comparing
two integers (ifindex), but they don't require the interface to exist
when the rule is added, and they can properly cope with the named
interface being deleted and re-added later.

[PATCH] meson: allow systemd sysusersdir to be changed
by Daniel P. Berrangé
We currently hardcode the systemd sysusersdir, but it is desirable to be
able to choose a different location in some cases. For example, Fedora
flatpak builds change the RPM %_sysusersdir macro, but we can't currently
honour that.

[PATCH] rpm: drop cyrus-sasl dep
by Daniel P. Berrangé
We link to libsasl2.so, so get a dep on cyrus-sasl-libs automatically.
The dep on cyrus-sasl-gssapi gets us the mechanism that matches our
default config.
The 'cyrus-sasl' package merely contains some man pages and the
saslauthd daemon, which is not required by libvirt. This dep appears
to have been redundant since we first added in

Schema test result can be inverted by naming the file with
'-invalid.xml' suffix. In such case the test will require that the XML
has invalid schema. Additionally it's also possible by adding an
exception in virschematest, but we have more than a few tests with the
suffix in qemuxmlconftest.

[PATCH] qemu_block: Validate number of hosts for iSCSI disk device
by Rayhan Faizel
An iSCSI device with zero hosts will result in a segmentation fault. This patch
adds a check for the number of hosts, which must be one in the case of iSCSI.
Minimal reproducing XML:
<domain type='qemu'>
<name>MyGuest</name>
<uuid>4dea22b3-1d52-d8f3-2516-782e98ab3fa0</uuid>
<os>
<type arch='x86_64'>hvm</type>
</os>

<devices>
<disk type='network'>

<target dev='vda'/>

[PATCH 0/2] lib: Annotate more functions as NULL terminated

I'm working on something that's calling qemuMonitorCreateObjectProps()

sentinel. This sparked me to look at other functions that might be
missing the G_GNUC_NULL_TERMINATED attribute too and found some.
