Subject: [PATCH] qemu: Use GICv2 for aarch64/virt TCG guests
There are currently some limitations in the emulated GICv3
that make it unsuitable as a default. Use GICv2 instead.

Subject: [PATCH] gic: Remove VIR_GIC_VERSION_DEFAULT
The QEMU default is GICv2, and some of the code in libvirt
relies on the exact value. Stop pretending that's not the
case and use GICv2 explicitly where needed.

Subject: [PATCH] Revert "qemu: propagate bridge MTU into qemu "host_mtu"
option"
This reverts commit 2841e675.
It turns out that adding the host_mtu field to the PCI capabilities in
the guest bumps the length of PCI capabilities beyond the 32 byte
boundary, so the virtio-net device gets 64 bytes of ioport space
instead of 32, which offsets the address of all the other following
devices. Migration doesn't work very well when the location and length
of PCI capabilities of devices is changed between source and
destination.
This means that we need to make sure that the absence/presence of
host_mtu on the qemu commandline always matches between source and
destination, which means that we need to make setting of host_mtu an
opt-in thing (it can't happen automatically when the bridge being used
has a non-default MTU, which is what commit 2841e675 implemented).
I do want to re-implement this feature with an <mtu auto='on'/>
setting, but probably won't backport that to any stable branches, so
I'm first reverting the original commit, and that revert can be pushed
to the few releases that have been made since the original (3.1.0 -
3.3.0)

Subject: [PATCH] cpu: Introduce virCPUCopyMigratable
This new internal API makes a copy of virCPUDef while removing all
features which would block migration. It uses cpu_map.xml as a database
of such features, which should only be used as a fallback when we cannot
get the data from a hypervisor. The main goal of this API is to decouple
this filtering from virCPUUpdate so that the hypervisor driver can
filter the features according to the hypervisor.

Subject: [PATCH] qemu: Move qemuCaps host CPU data in a struct
We need to store several CPU related data structure for both KVM and
TCG. So instead of keeping two different copies of everything let's
make a virQEMUCapsHostCPUData struct and use it twice.

Subject: [PATCH] qemu: Prepare qemuCaps for multiple host CPU defs
Soon we will need to store multiple host CPU definitions in
virQEMUCapsHostCPUData and qemuCaps users will want to request the one
they need. This patch introduces virQEMUCapsHostCPUType enum which will
be used for specifying the requested CPU definition.

Subject: [PATCH] qemu: Pass migratable host CPU model to virCPUUpdate
We already know from QEMU which CPU features will block migration. Let's
use this information to make a migratable copy of the host CPU model and
use it for updating guest CPU specification. This will allow us to drop
feature filtering from virCPUUpdate where it was just a hack.

Subject: [PATCH] cpu: Introduce virCPUGetHostIsSupported
Sometimes we want to call virCPUGetHost only when it is implemented for
a given architecture to avoid logging expected and possibly misleading
errors. The new virCPUGetHostIsSupported API may be used to guard such
calls to virCPUGetHost.

Subject: [PATCH] qemu: Use more data for comparing CPUs
With QEMU older than 2.9.0 libvirt uses CPUID instruction to determine
what CPU features are supported on the host. This was later used when
checking compatibility of guest CPUs. Since QEMU 2.9.0 we ask QEMU for
the host CPU data. But the two methods we use usually provide disjoint
sets of CPU features because QEMU/KVM does not support all features
provided by the host CPU and on the other hand it can enable some
feature even if the host CPU does not support them.
So if there is a domain which requires a CPU features disabled by
QEMU/KVM, libvirt will refuse to start it with QEMU > 2.9.0 as its guest
CPU is incompatible with the host CPU data we got from QEMU. But such
domain would happily start on older QEMU (of course, the features would
be missing the guest CPU). To fix this regression, we need to combine
both CPU feature sets when checking guest CPU compatibility.

Subject: [PATCH] Avoid hidden cgroup mount points
Currently the scan of the /proc/mounts file used to find cgroup mount
points doesn't take into account that mount points may hidden by other
mount points. For, example in certain Kubernetes environments the
/proc/mounts contains the following lines:
cgroup /sys/fs/cgroup/net_prio,net_cls cgroup ...
tmpfs /sys/fs/cgroup tmpfs ...
cgroup /sys/fs/cgroup/net_cls,net_prio cgroup ...
In this particular environment the first mount point is hidden by the
second one. The correct mount point is the third one, but libvirt will
never process it because it only checks the first mount point for each
controller (net_cls in this case). So libvirt will try to use the first
mount point, which doesn't actually exist, and the complete detection
process will fail.
To avoid that issue this patch changes the virCgroupDetectMountsFromFile
function so that when there are duplicates it takes the information from
the last line in /proc/mounts. This requires removing the previous
explicit condition to skip duplicates, and adding code to free the
memory used by the processing of duplicated lines.

Subject: [PATCH] docs: schema: make disk driver name attribute optional
/domain/devices/disk/driver/@name is not a required or mandatory
attribute according to formatdomain, and indeed it was agreed on
IRC that the attribute is "optional for input, recommended (but
not required) for output". Currently the schema requires the
attribute, causing virt-xml-validate to fail on disk config where
the driver name is not explicitly specified. E.g.
# cat test.xml | grep -A 5 cdrom
<disk type='file' device='cdrom'>
<driver type='raw'/>
<target dev='hdb' bus='ide'/>
<readonly/>
<address type='drive' controller='0' bus='0' target='0' unit='1'/>
</disk>
# virt-xml-validate test.xml
Relax-NG validity error : Extra element devices in interleave
test.xml:21: element devices: Relax-NG validity error : Element domain failed to validate content
test.xml fails to validate
Relaxing the name attribute to be optional fixes the validation
# virt-xml-validate test.xml
test.xml validates

Subject: [PATCH] security: dac: relabel spice rendernode
For a logged in user this a path like /dev/dri/renderD128 will have
default ownership root:video which won't work for the qemu:qemu user,
so we need to chown it.
We only do this when mount namespaces are enabled in the qemu driver,
so the chown'ing doesn't interfere with other users of the shared
render node path

Subject: [PATCH] qemuDomainBuildNamespace: Move /dev/* mountpoints later
When setting up mount namespace for a qemu domain the following
steps are executed:
1) get list of mountpoints under /dev/
2) move them to /var/run/libvirt/qemu/$domName.ext
3) start constructing new device tree under /var/run/libvirt/qemu/$domName.dev
4) move the mountpoint of the new device tree to /dev
5) restore original mountpoints from step 2)
Note the problem with this approach is that if some device in step
3) requires access to a mountpoint from step 2) it will fail as
the mountpoint is not there anymore. For instance consider the
following domain disk configuration:
<disk type='file' device='disk'>
<driver name='qemu' type='raw'/>
<source file='/dev/shm/vhostmd0'/>
<target dev='vdb' bus='virtio'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x0a' function='0x0'/>
</disk>
In this case operation fails as we are unable to create vhostmd0
in the new device tree because after step 2) there is no /dev/shm
anymore. Leave aside fact that we shouldn't try to create devices
living in other mountpoints. That's a separate bug that will be
addressed later.
Currently, the order described above is rearranged to:
1) get list of mountpoints under /dev/
2) start constructing new device tree under /var/run/libvirt/qemu/$domName.dev
3) move them to /var/run/libvirt/qemu/$domName.ext
4) move the mountpoint of the new device tree to /dev
5) restore original mountpoints from step 3)

Subject: [PATCH] qemu: ensure TLS clients always verify the server certificate
The default_tls_x509_verify (and related) parameters in qemu.conf
control whether the QEMU TLS servers request & verify certificates
from clients. This works as a simple access control system for
servers by requiring the CA to issue certs to permitted clients.
This use of client certificates is disabled by default, since it
requires extra work to issue client certificates.
Unfortunately the code was using this configuration parameter when
setting up both TLS clients and servers in QEMU. The result was that
TLS clients for character devices and disk devices had verification
turned off, meaning they would ignore errors while validating the
server certificate.
This allows for trivial MITM attacks between client and server,
as any certificate returned by the attacker will be accepted by
the client.
This is assigned CVE-2017-1000256 / LSN-2017-0002

Subject: [PATCH] domain_conf: add "default" to list of valid spice channels
qemu's behavior in this case is to change the spice server behavior to
require secure connection to any channel not otherwise specified as
being in plaintext mode. libvirt doesn't currently allow requesting this
(via plaintext-channel=<channel name>).

Subject: [PATCH] qemu: replace deprecated fedora-13 machine type with pc-0.14
This addresses https://bugzilla.redhat.com/show_bug.cgi?id=754772 .
It should only be applied to Fedora builds of libvirt, F15 and
later, so there is no upstream equivalent patch.
Background:
During the lifetime of Fedora 13, some features were backported into
the F13 build of qemu-kvm from upstream. These features were part of
the functionality of machine type "pc-0.13" in upstream qemu-kvm, so a
special "fedora-13" machine type was created for the F13 qemu-kvm.
Since "fedora-13" became the new "canonical machine type", all new
domains created with F13 libvirt tools by default contained that
machine type in their configuration file.
In Fedora 14, a patch was made to qemu to treat the fedora-13 machine
type as equivalent to "pc-0.13". When Fedora 15 was released, this was
inadvertently changed to make it equivalent to "pc-0.14".
With the release of Fedora 16, qemu-kvm initially removed support for
this machine type, which caused failure of many guest configurations
to start. qemu-kvm subsequently re-added the patch to support
fedora-13 (as equivalent to pc-0.14), but with the promise that they
could remove it with the release of Fedora 17. (see
https://bugzilla.redhat.com/show_bug.cgi?id=748218 ).
Solution:
In order to create a repeat of the recent problems, prior to F17
existing guest configurations need to be updated to change fedora-13
to pc-0.14 (which has been determined to be equivalent for all
practical purposes in both F15 and F16). That's what this patch does:
1) Each time libvirtd is started, it calls virDomainLoadAllConfigs()
which calls virDomainLoadConfig(); this function has been modified to
check for os.machine == "fedora-13", and change it to "pc-0.14" then
write the updated config back to disk.
2) Also, any other time a domain definition is parsed, the parsed
version in memory is changed to turn "fedora-13" into "pc-0.14". This
handles domains that had been saved to disk prior to the upgrade, and
are subsequently restarted.
3) Finally, whenever a domain definition is formatted into a string,
any occurrence of fedora-13 is replaced with pc-0.14 *directly in the
virDomainDef* (to avoid multiple warning messages for the same object
when it's formatted multiple times). This should deal with those cases
where a domain was running at the time of upgrade, and is later
saved/snapshotted.
I had considered doing this with some sed commands in the specfile,
but that wouldn't do anything to help the xml saved in image files.
(Also, one of the xml tests was using the machine type "fedora-13",
and since that machine type is treated specially by the rest of this
patch, it was failing. That has been changed in a separate patch,
which must be applied with this patch, and which *is* also upstream).

commit acbd4965c44c4dbc676dfe89aff970052e376073
Author: Daniel P. Berrange <berrange@redhat.com>
Date: Thu Jun 21 15:34:46 2012 +0100
Add support for shared sanlock leases
A sanlock lease can be marked as shared (rather
than exclusive) using SANLK_RES_SHARED flag. This
adds support for that flag and ensures that in auto
disk mode, any shared disks use shared leases. This
also makes any read-only disks be completely
ignored.
These changes remove the need for the option
ignore_readonly_and_shared_disks
so that is removed
