Subject: [PATCH] conf: introduce support for multiple ACPI tables
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Currently we parse
<os>
<acpi>
<table type="slic">...path...</table>
</acpi>
</os>
into a flat 'char *slic_table' field which is rather an anti-pattern
as it has special cased a single attribute type.
This rewrites the internal design to permit multiple table types to
be parsed, should we add more in future. Each type is currently
permitted to only appear once.

Subject: [PATCH] libxl: support 'rawset' ACPI table type
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This fixes representation of the 'acpi_firmware' config in the Xen
driver, which repesents a concatenation of tables of any type.
Use of 'type=slic' is accepted on input for backwards compatibility.

previous patch made it fatal for vhost-user interfaces to be configured
without shared memory this warning code can be deleted.

Subject: [PATCH] qemuValidateDomainDeviceDefNetwork: Require shared memory for
all vhost-user interfaces
Currently we produce only a warning into the log if a non-passt
vhost-user interface is configured with shared memory.
Since we do make it fatal with all other vhost-user types, fix the check
to trigger also for normal-vhost-user interfaces.
Since passt-based vhost-user interfaces are checked separately the check
will no longer be required.

Subject: [PATCH] qemuxmlconftest: Include shared memory 'net-vhostuser' test
cases
The vhost-user protocol requires shared memory support to work properly.
Our test XMLs didn't have it configured as for interface the check if
shared memory is present only produces a warning instead of a proper
error.
Upcoming patches will be moving the check to become fatal so the test
cases need to be fixed first.

Subject: [PATCH] rpc: remove logind support for virNetDaemon
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The virNetDaemon code now only concerns itself with preventing auto
shutdown of the local daemon. Logind is now handled by the new
virInhibitor object, for QEMU, LXC and LibXL. This fixes two notable
bugs
* Running virtual networks would prevent system shutdown
* Loaded ephemeral secrets would prevent system shutdown
Fixes 9e3cc0ff5e81ed2056a6a528893fd2cb5609d70b
Fixes 37800af9a400385801da6d73654249fdb51a93d8

Subject: [PATCH] src: convert drivers over to new virInhibitor APIs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This initial conversion of the drivers switches them over to use
the virInhibitor APIs in local daemon only mode. Communication to
logind is still handled by the virNetDaemon class logic.
This mostly just replaces upto 3 fields in the driver state
with a single new virInhibitor object, but otherwise should not
change functionality besides replacing atomics with mutex protected
APIs.
The exception is the LXC driver which has been trying to inhibit
shutdown shutdown but silently failing to, since nothing ever
remembered to set the 'inhibitCallback' pointer in the driver
state struct.
Reviewed-by: Michal Privoznik <mprivozn@redhat.com>
Signed-off-by: Daniel P. Berrangé <berrange@redhat.com>
(cherry picked from commit 48f0b6dfa12563f0006d2de4b0f85599e20f9449)
Resolves: https://issues.redhat.com/browse/RHEL-83064

Subject: [PATCH] src: introduce 'raw' and 'rawset' ACPI table types
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The QEMU driver has only accepted type=slic even though QEMU is able to
accept individual tables of any type, without needing to specify a
signature. Introduce type=raw to address this usage scenario. Contrary
to other types, this one may appear multiple times.
The Xen driver has mistakenly accepted type=slic and use it to set the
Xen acpi_firmware setting, which performs a simple passthrough of
multiple concatenated data table. Introduce type=rawset to address
this usage scenario.

When VIR_INHIBITOR_WHAT_NONE is passed to virInhibitorNew, it is
an indication that daemon shutdown should be inhibited, but no
OS level inhibitors acquired. This is done by the virtnetworkd
daemon, for example, to prevent shutdown while running virtual
machines are present, without blocking / delaying OS shutdown.
Unfortunately the code forgot to skip the DBus call in this case,
resulting in errors being logged.

Subject: [PATCH] util: introduce object for holding a system inhibitor lock
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The system inhibitor locks are currently handled by code in the
virNetDaemon class. The driver code invokes a callback provided
by the daemon when it wants to start or end inhibition.
When the first inhibition is started, the daemon will call out
to logind to apply it system wide.
This has many flaws
* A single message is registered with logind regardless of
what driver holds the inhibition
* An inhibition of daemon shutdown can't be acquired
without also inhibiting system shutdown
* Config of the inhibitions cannot be tailored by the
driver
The new virInhibitor object addresses these:
* The object directly manages an inhibition with logind
privately to the driver, enabling custom messages to
be set.
* It is possible to acquire an inhibition locally to the
daemon without forwarding it to logind.
