Subject: [PATCH] RHEL: Hack around changed Broadwell/Haswell CPUs
RHEL-only
Upstream tried to solve the change of Broadwell and Haswell CPUs by
removing rtm and hle features from the corresponding CPU models for new
machine types. Then they reverted this and introduced new *-noTSX models
instead. However, the original fix was backported to RHEL.
This patch makes sure Broadwell and Haswell will always contain rtm and
hle features regardless on RHEL version or machine type used.

RHEL-only
Fix the logic to handle the case where if the <shareable/> element
was removed from the domain <hostdev.../>, then we have to reset the
SGIO value back to 0. Without this patch the check for not shareable
and return 0 would bypass resetting the value back to 0.

Rather than initializing to -1 and then setting to the result
of a boolean check (either 0 or 1), let's just initialize @val
to 0 and then only change to 1 if conditions are "right".

Commit 861a1a4d2 moved the qemuIsSharedHostdev filter in the
HOSTDEV half of the logic to allow calling qemuGetHostdevPath;
however, that neglected to check whether the SCSI hostdev was
using the iSCSI protocol which has a different overlayed struct
format (u.iscsi vs. u.host) resulting in attempted access of
u.host when calling virSCSIDeviceGetDevName.

Subject: [PATCH] RHEL: qemuSetUnprivSGIO: Actually use calculated @sysfs_path
to set unpriv_sgio
In previous commits I've attempted to make qemuSetUnprivSGIO()
construct a generic enough path for SCSI devices to set
unpriv_sgio. However, virSetDeviceUnprivSGIO() does not care
about that - it constructs the path on it's own again. This is
suboptimal in either case - we already have the path constructed.

Subject: [PATCH] RHEL: virscsi: Introduce and use
virSCSIDeviceGetUnprivSGIOSysfsPath()
When constructing a path to the 'unpriv_sgio' file of given SCSI
device we don't need to go through /dev/* and major() + minor()
path. The generated path points to
/sys/dev/block/MAJ:MIN/queue/unpriv_sgio which is wrong if the
SCSI device in question is not a block device. We can generate a
different path: /sys/bus/scsi/devices/X:X:X:X/unpriv_sgio where
the file is directly accessible regardless of the SCSI device
type.

Subject: [PATCH] api: disallow virDomainAgentSetResponseTimeout() on read-only
connections
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This function changes the amount of time that libvirt waits for a
response from the guest agent for all guest agent commands. Since this
is a configuration change, it should not be allowed on read-only
connections.

Subject: [PATCH] conf: Add support for modifying ssl validation for https/ftps
disks
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
To allow turning off verification of SSL cerificates add a new element
<ssl> to the disk source XML which will allow configuring the validation
process using the 'verify' attribute.

Subject: [PATCH] conf: Don't generate machine names with a dot
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
According to the linked BZ, machined expects either valid
hostname or valid FQDN (see systemd commit
v239-3092-gd65652f1f2). While in case of multiple dots, a
trailing one doesn't violate FQDN, it does violate the rule in
case of something simple, like "domain.". But it's safe to remove

Subject: [PATCH] conf: add new PCI_CONNECT flag AUTOASSIGN
This new flag will be set for any controller that we decide can have
devices assigned to it automatically during PCI device assignment. In
the past PCI_CONNECT_TYPE_HOTPLUGGABLE was used for this purpose, but
that is overloading that flag, and no longer technically correct; what
we *really* want is to auto-assign devices to any pcie-root-port or
pcie-switch-downstream-port regardless of whether or not that
controller happens to have hotplug enabled.
This patch just adds the flag, but doesn't use it at all. Note that
the numbering of all the other flags was changed in order to insert
the new flag near the beginning of the list; that doesn't cause any
problem because the connect flags aren't stored anywhere between runs
of libvirtd.

Subject: [PATCH] conf: backup: Store incremental backup checkpoint name
per-disk
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
In preparation to allow heterogenous backups store the 'incremental'
field per-disk and fill it by default from the per-backup field.
Having this will be important once we'll want to allow incremental
backup working while hotplugging a new disk.

Subject: [PATCH] conf: check HOTPLUGGABLE connect flag when validating a PCI
address
The HOTPLUGGABLE flag is set for appropriates buses in a PCI address
set, and thnis patch updates virDomainPCIAddressFlagsCompatible() to
check the HOTPLUGGABLE flag when searching for a suitable bus/slot for
a device. No devices request HOTPLUGGABLE though (yet), so there is no
observable effect.

Subject: [PATCH] conf: during PCI hotplug, require that the controller support
hotplug
Before this patch we would simply rely on QEMU failing to attach the
device. Since we have a flag in the address set telling us which
controllers support hotplug, we can fail the operation sooner.
This also assures that when hotplugging with no provided PCI address,
that we skip any controllers with hotplug='off', and attempt to assign
the device to a controller that not only supports hotplug, but also
has it enabled.

Subject: [PATCH] conf: new attribute "hotplug" for pci controllers
a <controller type='pci'...> element can now have a "hotplug"
attribute in the <target> subelement. This is intended to control
whether or not the slot(s) of the controller support
hotplugging/unplugging a device:
<controller type='pci' model='pcie-root-port'>
<target hotplug='off'/>
</controller>
The default value of hotplug is "on".
Since support for configuring such an option is hypervisor-dependent
(and will vary among different types of PCI controllers even on a
single hypervisor), no validation is done in this patch - that
validation will be done in the patch that wires support for the
setting into the hypervisor.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The subelement <teaming> of <interface> devices is used to configure a
simple teaming association between two interfaces in a domain. Example:
<interface type='bridge'>
<source bridge='br0'/>
<model type='virtio'/>
<mac address='00:11:22:33:44:55'/>
<alias name='ua-backup0'/>
<teaming type='persistent'/>
</interface>
<interface type='hostdev'>
<source>
<address type='pci' bus='0x02' slot='0x10' function='0x4'/>
</source>
<mac address='00:11:22:33:44:55'/>
<teaming type='transient' persistent='ua-backup0'/>
</interface>
The interface with <teaming type='persistent'/> is assumed to always
be present, while the interface with type='transient' may be be
unplugged and later re-plugged; the persistent='blah' attribute (and
in the one currently available implementation, also the matching MAC
addresses) is what associates the two devices with each other. It is
up to the hypervisor and the guest network drivers to determine what
to do with this information.

Subject: [PATCH] conf/qemu:
s/VIR_PCI_CONNECT_HOTPLUGGABLE/VIR_PCI_CONNECT_AUTOASSIGN/g
When the HOTPLUGGABLE flag was originally added, it was set for all
the PCI controllers that accepted hotplugged devices, and requested
for all devices that were auto-assigned to a controller. While we're
still autoassigning to the same list of controllers, those controllers
may or may not support hotplug, so let's use the flag that fits what
we're actually doing.

While 'namespace' is not a reserved word in C, it is in C++. Our
compilers are happy with it but syntax-hilighting in some editors
hilights is as a keyword. Rename it to prevent confusion.

Subject: [PATCH] conf: simplify logic when checking for AUTOASSIGN PCI
addresses
Old behavior: If the address was manually provided by config, copy
device AUTOASSIGN flag into the bus flag, and then later on in the
function *always* check for a match of the flags (which will always
match if the address came from config, since we just copied it).
New behavior: Don't mess with the bus flags - just directly check if
the AUTOASSIGN flag matches in bus and dev, but only make the check if
the address didn't come from config (i.e. it was auto-assigned by
libvirt).

Subject: [PATCH] cpu: Honor check='full' for host-passthrough CPUs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The check attribute was completely ignored for host-passthrough CPUs
even if they explicitly requested some features to be enabled. For
example, a domain with the following CPU definition
<cpu mode='host-passthrough' check='full'>
<feature policy='require' name='svm'/>
</cpu>
would happily start even when 'svm' cannot be enabled.
Let's call virCPUArchUpdateLive for host-passthrough CPUs with
VIR_CPU_CHECK_FULL to make sure the architecture specific code can
validate the provided virtual CPU against the desired definition.

The virCapabilitiesGetNodeInfo() function has the usual return
value semantics for integeres: a negative value means an error,
zero or a positive value means success. However, the function
call done in virCPUProbeHost() doesn't check for the return value
accordingly.

Subject: [PATCH] cpu_map: Add Cooperlake x86 CPU model
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The stepping range (10-11) is likely incomplete. QEMU uses 10 and the
CPUID data for Cooperlake show 11. We will update the range if needed
once more details about he CPU are available.

Subject: [PATCH] cpu_map: Add <decode> element to x86 CPU model definitions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The element specifies whether a particular CPU model can be used when
creating a CPU definition from raw CPUID/MSR data. The @host attribute
determines whether the CPU model can be used (host='on') for creating
CPU definition for host capabilities. Usability of the model for domain
capabilities and host-model CPU definitions is controlled by the @guest
attribute.

Message-Id: <59287d64100517e89dbd3a88af6fec4755ceab42@dist-git>
From: Christian Ehrhardt <christian.ehrhardt@canonical.com>

Subject: [PATCH] cpu_map: Add more -noTSX x86 CPU models
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
One of the mitigation methods for TAA[1] is to disable TSX
support on the host system. Linux added a mechanism to disable
TSX globally through the kernel command line, and many Linux
distributions now default to tsx=off. This makes existing CPU
models that have HLE and RTM enabled not usable anymore.
Add new versions of all CPU models that have the HLE and RTM
features enabled, that can be used when TSX is disabled in the
host system.
On systems disabling the features without those types defined
in cpu-maps users end up without modern CPU types in the list
of usable CPUs to use in the likes of virsh domcapabilities
or tools higher in the stack like virt-manager.
This adds:
-Cascadelake-Server-noTSX
-Icelake-Client-noTSX
-Icelake-Server-noTSX
-Skylake-Server-noTSX-IBRS
-Skylake-Client-noTSX-IBRS
Introduced in QEMU by commit v4.2.0-rc2-3-g9ab2237f19 (function)
and commit v4.2.0-rc2-4-g02fa60d101 (names)

Subject: [PATCH] cpu_map: Distinguish Cascadelake-Server from Skylake-Server
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The signatures of these two CPU model differ only in stepping as both
report family 6 and model 85. Skylake-Server uses stepping 4 or less and
Cascadelake-Server uses stepping 5..7.

Subject: [PATCH] cpu_map: Don't use new noTSX models for host-model CPUs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Host-model CPU definitions (and domain capabilities) will use the
original CPU models (without noTSX in their name) and explicitly disable
hle and rtm features. This way domains with host-model CPUs will be
migratable even to older versions of libvirt which do not support the
noTSX model variants.
The new models will be advertised in host capabilities and they may
be used explicitly with custom CPUs.

Subject: [PATCH] cpu_x86: Add support for stepping part of CPU signature
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
CPU models defined in the cpu_map can use signature/@stepping attribute
to match a limited set of stepping numbers. The value is a bitmap for
bits 0..15 each corresponding to a single stepping value. For example,
stepping='4-6,9' will match 4, 5, 6, and 9. Omitting the attribute is
equivalent to stepping='0-15'.

Subject: [PATCH] cpu_x86: Drop noTSX hint for incompatible CPUs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The hint was introduced a long time ago when broken TSX implementation
was found in Haswell and Broadwell CPUs. Since then many more CPUs with
TSX were introduced and and disabled due to TAA vulnerability.
Thus the hint is not very useful and I think removing it is a better
choice then updating it to cover all current noTSX models.
This partially reverts:

family and model numbers. Let's store the signatures in the same way in
our runtime representation of the cpu_map.

+================================
+Protected Virtualization on s390
+================================
+
+.. contents::
+
+Overview
+========
+
+Protected virtualization, also known as IBM Secure Execution is a
+hardware-based privacy protection technology for s390x (IBM Z).
+It allows to execute virtual machines such that the host system
+has no access to a VM's state and memory contents.
+
+Unlike other similar technologies, the memory of a running guest
+is not encrypted but protected by hardware access controls, which
+may only be manipulated by trusted system firmware, called
+ultravisor.
+
+For the cases where the host needs access to guest memory (e.g. for
+paging), it can request pages to be exported to it. The exported page
+will be encrypted with a unique key for the running guest by the
+ultravisor. The ultravisor also computes an integrity value for
+the page, and stores it in a special table, together with the page
+index and a counter. This way it can verify the integrity of
+the page content upon re-import into the guest.
+
+In other cases it may be necessary for a guest to grant the host access
+to dedicated memory regions (e.g. for I/O). The guest can request
+that the ultravisor removes the memory protection from individual
+pages, so that they can be shared with the host. Likewise, the
+guest can undo the sharing.
+
+A secure guest will initially start in a regular non-protected VM.
+The start-up is controlled by a small bootstrap program loaded
+into memory together with encrypted operating system components and
+a control structure (the PV header).
+The operating system components (e.g. Linux kernel, initial RAM
+file system, kernel parameters) are encrypted and integrity
+protected. The component encryption keys and integrity values are
+stored in the PV header.
+The PV header is wrapped with a public key belonging to a specific
+system (in fact it can be wrapped with multiple such keys). The
+matching private key is only accessible by trusted hardware and
+firmware in that specific system.
+Consequently, such a secure guest boot image can only be run on the
+systems it has been prepared for. Its contents can't be decrypted
+without access to the private key and it can't be modified as
+it is integrity protected.
+
+Host Requirements
+=================
+
+IBM Secure Execution for Linux has some hardware and firmware
+requirements. The system hardware must be an IBM z15 (or newer),
+or an IBM LinuxONE III (or newer).
+
+It is also necessary that the IBM Secure Execution feature is
+enabled for that system. With libvirt >= 6.5.0 you can run
+``libvirt-host--validate`` or otherwise check for facility '158', e.g.
+
+::
+
+ $ grep facilities /proc/cpuinfo | grep 158
+
+The kernel must include the protected virtualization support
+which can be verified by checking for the presence of directory
+``/sys/firmware/uv``. It will only be present when both the
+hardware and the kernel support are available.
+
+Finally, the host operating system must donate some memory to
+the ultravisor needed to store memory security information.
+This is achieved by specifying the following kernel command
+line parameter to the host boot configuration
+
+::
+
+ prot_virt=1
+
+
+Guest Requirements
+==================
+
+Guest Boot
+----------
+
+To start a guest in protected virtualization secure mode, the
+boot image must have been prepared first with the program
+``genprotimg`` using the correct public key for this host.
+``genprotimg`` is part of the package ``s390-tools``, or
+``s390-utils``, depending on the Linux distribution being used.
+It can also be found at
+`<https://github.com/ibm-s390-tools/s390-tools/tree/master/genprotimg>`_
+
+The guests have to be configured to use the host CPU model, which
+must contain the ``unpack`` facility indicating ultravisor guest support.
+
+With the following command it's possible to check whether the host
+CPU model satisfies the requirement
+
+::
+
+ $ virsh domcapabilities | grep unpack
+
+which should return
+
+::
+
+ <feature policy='require' name='unpack'/>
+
+Note that on hosts with libvirt < 6.5.0 if the check fails despite
+the host system actually supporting protected virtualization guests,
+this can be caused by a stale libvirt capabilities cache.
+To recover, run the following commands
+
+::
+
+ $ systemctl stop libvirtd
+ $ rm /var/cache/libvirt/qemu/capabilities/*.xml
+ $ systemctl start libvirtd
+
+
+Guest I/O
+---------
+
+Protected virtualization guests support I/O using virtio devices.
+As the virtio data structures of secure guests are not accessible
+by the host, it is necessary to use shared memory ('bounce buffers').
+
+To enable virtio devices to use shared buffers, it is necessary
+to configure them with platform_iommu enabled. This can done by adding
+``iommu='on'`` to the driver element of a virtio device definition in the
+guest's XML, e.g.
+
+::
+
+ <interface type='network'>
+ <source network='default'/>
+ <model type='virtio'/>
+ <driver name='vhost' iommu='on'/>
+ </interface>
+
+It is mandatory to define all virtio bus devices in this way to
+prevent the host from attempting to access protected memory.
+Ballooning will not work and is fenced by QEMU. It should be
+disabled by specifying
+
+::
+
+ <memballoon model='none'/>
+
+Finally, the guest Linux must be instructed to allocate I/O
+buffers using memory shared between host and guest using SWIOTLB.
+This is done by adding ``swiotlb=nnn`` to the guest's kernel command
+line string, where ``nnn`` stands for the number of statically
+allocated 2K entries. A commonly used value for swiotlb is 262144.
+
+Example guest definition
+========================
+
+Minimal domain XML for a protected virtualization guest, essentially
+it's mostly about the ``iommu`` property
+
+::
+
+ <domain type='kvm'>
+ <name>protected</name>
+ <memory unit='KiB'>2048000</memory>
+ <currentMemory unit='KiB'>2048000</currentMemory>
+ <vcpu>1</vcpu>
+ <os>
+ <type arch='s390x'>hvm</type>
+ </os>
+ <cpu mode='host-model'/>
+ <devices>
+ <disk type='file' device='disk'>
+ <driver name='qemu' type='qcow2' cache='none' io='native' iommu='on'>
+ <source file='/var/lib/libvirt/images/protected.qcow2'/>
+ <target dev='vda' bus='virtio'/>
+ </disk>
+ <interface type='network'>
+ <driver iommu='on'/>
+ <source network='default'/>
+ <model type='virtio'/>
+ </interface>
+ <console type='pty'/>
+ <memballoon model='none'/>
+ </devices>
