+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: 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] 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] 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
