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] 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
|
||||

TPM 2 does not implement sysfs files for cancellation of commands.
|

We therefore use /dev/null for the cancel path passed to QEMU.

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

Subject: [PATCH] Handle kernels with no ipv6 support
|
||||
|
||||
If the ipv6 kernel module is not loaded, then we get this when starting
|
||||
a virtual network:
|
||||
|
||||
libvir: Network Config error :
|
||||
cannot enable /proc/sys/net/ipv6/conf/virbr0/disable_ipv6:
|
||||
No such file or directory
|
||||
|
||||
If disable_ipv6 is not present, we should just merrily continue on our
|
||||
way.
|
||||
|
||||
* src/network_driver.c: make networkDisableIPV6() not fail if the kernel
|
||||
has no ipv6 support
|
||||
|
||||
(cherry picked from commit f5a8f969dd92ec2744e1eec5d35288d5fbcded22)

Subject: [PATCH] Make LXC / UML drivers robust against NUMA topology brokenness
|
||||
|
||||
Some kernel versions expose broken NUMA topology for some machines.
|
||||
This causes the LXC/UML drivers to fail to start. QEMU driver was
|
||||
already fixed for this problem
|
||||
|
||||
* src/lxc_conf.c: Log and ignore failure to populate NUMA info
|
||||
* src/uml_conf.c: Log and ignore failure to populate NUMA info
|
||||
* src/capabilities.c: Reset nnumaCell to 0 after freeing
|
||||

Subject: [PATCH] Add host PCI device hotplug support
|
||||
|
||||
Attaching a host PCI device to a qemu guest is done with a
|
||||
straightforward 'pci_add pci_addr auto host host=XX:XX.X' command.
|
||||
|
||||
Like with NIC and disk hotplug, we need to retain the guest PCI address
|
||||
assigned by qemu so that we can use it for hot-unplug.
|
||||
|
||||
Identifying a device for detach is done using the host PCI address.
|
||||
|
||||
Managed mode is handled by detaching/resetting the device before
|
||||
attaching it to the guest and re-attaching it after detaching it from
|
||||
the guest.
|
||||
|
||||

Maybe it's just me, but I try to select an item from the tree using

double-click and get annoyed when "+-" gets included in the selection.

Subject: [PATCH] Maintain a list of active PCI hostdevs and use it in pciResetDevice()
|
||||
|
||||
https://bugzilla.redhat.com/499678
|
||||
|
||||
First we add a pciDeviceList type and add a qemuGetPciHostDeviceList()
|
||||
function to build a list from a domain definition. Use this in
|
||||
prepare/re-attach to simplify things and eliminate the multiple
|
||||
pciGetDevice() calls.
|
||||
|
||||
Then, as we start/shutdown guests we can add or delete devices as
|
||||
appropriate from a list of active devices.
|
||||
|
||||
Finally, in pciReset(), we can use this to determine whether its safe to
|
||||
reset a device as a side effect of resetting another device.

Subject: [PATCH] Allow PM reset on multi-function PCI devices
|
||||
|
||||
https://bugzilla.redhat.com/515689
|
||||
|
||||
It turns out that a PCI Power Management reset only affects individual
|
||||
functions, and not the whole device.
|
||||
|
||||
The PCI Power Management spec talks about resetting the 'device' rather
|
||||
than the 'function', but Intel's Dexuan Cui informs me that it is
|
||||
actually a per-function reset.
|
||||
|
||||
Also, Yu Zhao has added pci_pm_reset() to the kernel, and it doesn't
|
||||
reject multi-function devices, so it must be true! :-)
|
||||
|
||||
(A side issue is that we could defer the PM reset to the kernel if we
|
||||
could detect that the kernel has PM reset support, but barring version
|
||||
number checks we don't have a way to detect that support)
|
||||
|
||||
* src/pci.c: remove the pciDeviceContainsOtherFunctions() check from
|
||||
pciTryPowerManagementReset() and prefer PM reset over bus reset
|
||||
where both are available

||||

Subject: [PATCH] Run 'cont' on successful migration finish.
|
||||
|
||||
https://bugzilla.redhat.com/516187
|
||||
|
||||
As of qemu 0.10.6, qemu now honors the -S flag on incoming migration.
|
||||
That means that when the migration completes, we have to issue a
|
||||
'cont' command to get the VM running again. We do it unconditionally
|
||||
since it won't hurt on older qemu.
|
||||

||||

Subject: [PATCH] Improve PCI host device reset error message
|
||||
|
||||
https://bugzilla.redhat.com/499678
|
||||
|
||||
Currently, if we are unable to reset a PCI device we return a fairly
|
||||
generic 'No PCI reset capability available' error message.
|
||||
|
||||
Fix that by returning an error from the individual reset messages and
|
||||
using that error to construct the higher level error mesage.
|
||||
|
||||
* src/pci.c: set errors in pciTryPowerManagementReset() and
|
||||
pciTrySecondaryBusReset() on failure; use those error messages
|
||||
in pciResetDevice(), or explain that no reset support is available
|
||||

||||

Subject: [PATCH] Reset and re-attach PCI host devices on guest shutdown
|
||||
|
||||
https://bugzilla.redhat.com/499561
|
||||
|
||||
When the guest shuts down, we should attempt to restore all PCI host
|
||||
devices to a sane state.
|
||||
|
||||
In the case of managed hostdevs, we should reset and re-attach the
|
||||
devices. In the case of unmanaged hostdevs, we should just reset them.
|
||||
|
||||
Note, KVM will already reset assigned devices when the guest shuts
|
||||
down using whatever means it can, so we are only doing it to cover the
|
||||
cases the kernel can't handle.
|
||||
|
||||
* src/qemu_driver.c: add qemuDomainReAttachHostDevices() and call
|
||||
it from qemudShutdownVMDaemon()
