Subject: [PATCH] qemu: Allow creating ppc64 guests with graphics and no USB
mouse
The existing behavior for ppc64 guests is to always add a USB
keyboard and mouse combo if graphics are present; unfortunately,
this means any attempt to use a USB tablet will cause both pointing
devices to show up in the guest, which in turn will result in poor
user experience.
We can't just stop adding the USB mouse or start adding a USB tablet
instead, because existing applications and users might rely on the
current behavior; however, we can avoid adding the USB mouse if a USB
tablet is already present, thus allowing users and applications to
create guests that contain a single pointing device.

Subject: [PATCH] qemu: Remove duplicated qemuAgentCheckError
Commit 5b3492fadb moved qemuAgentCheckError calls into
qemuAgentCommand for various reasons; however, subsequent
commit 0977b8aa0 adding a new command made call again
So let's just remove the duplicitous call from
qemuAgentGetInterfaces.

Subject: [PATCH] qemu: require reply from guest agent in
qemuAgentGetInterfaces
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Since its introduction in commit 0977b8aa071 (released in v1.2.14)
qemuAgentGetInterfaces calls qemuAgentCommand with needReply=false,
which allows qemuAgentCommand to return 0 even when it did not get
any reply from the agent.
Set needReply to true, since we dereference it right after.
This can be hit if libvirt is waiting for an event from the agent
(e.g. shutdown) and the agent cannot reply in time (e.g. due to
the guest being shut down), as reported in:

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)

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The microcode version checks are used to invalidate cached CPU data we
get from QEMU. To minimize /proc/cpuinfo parsing the microcode version
was only read when libvirtd started and cached for the daemon's
lifetime. However, the CPU microcode can change anytime (updating the
microcode package can automatically upload it to the CPU) and we need to
stop caching it to avoid using stale CPU model data.

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: Don't cache microcode version
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
My earlier commit be46f61326 was incomplete. It removed caching of
microcode version in the CPU driver, which means the capabilities XML
will see the correct microcode version. But it is also cached in the
QEMU capabilities cache where it is used to detect whether we need to
reprobe QEMU. By missing the second place, the original commit
be46f61326 made the situation even worse since libvirt would report
correct microcode version while still using the old host CPU model
(visible in domain capabilities XML).

Subject: [PATCH] locking: restrict sockets to mode 0600
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The virtlockd daemon's only intended client is the libvirtd daemon. As
such it should never allow clients from other user accounts to connect.
The code already enforces this and drops clients from other UIDs, but
we can get earlier (and thus stronger) protection against DoS by setting

Subject: [PATCH] logging: restrict sockets to mode 0600
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The virtlogd daemon's only intended client is the libvirtd daemon. As
such it should never allow clients from other user accounts to connect.
The code already enforces this and drops clients from other UIDs, but
we can get earlier (and thus stronger) protection against DoS by setting
the socket permissions to 0600

The virDomainSaveImageGetXMLDesc API is taking a path parameter,

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] 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] Revert "qemu: hotplug: Prepare disk source in
qemuDomainAttachDeviceDiskLive"
Preparing the storage source prior to assigning the alias will not work
as the names of the certain objects depend on the alias for the legacy
hotplug case as we generate the object names for the secrets based on
the alias.

Subject: [PATCH] tests: rewrite socket to do something sensible and reliable
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The current socket test is rather crazy in that it sets up a server
listening for sockets and then runs a client connect call, relying on
the fact that the kernel will accept this despite the application
not having called accept() yet. It then closes the client socket and
calls accept() on the server. On Linux accept() will always see that
the client has gone and so skip the rest of the code. On FreeBSD,
however, the accept sometimes succeeds, causing us to then go into
code that attempts to read and write to the client which will fail
aborting the test. The accept() never succeeds on FreeBSD guests
with a single CPU, but as you add more CPUs, accept() becomes more and
more likely to succeed, giving a 100% failure rate for the test when
using 8 CPUs.
This completely rewrites the test so that it is avoids this designed in
race condition. We simply spawn a background thread to act as the
client, which will read a byte from the server and write it back again.
The main thread can now properly listen and accept the client in a
synchronous manner avoiding any races.

but without checking the return status of virEventRunDefaultImpl
it's possible that the test could run infinitely.

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

For some reason, we completely ignore <on_reboot/> setting for
domains. The implementation is simply not there. It never was.

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
