+RH-Commit: [1/1] b5a1047750af32c0a261b8385ea0e819eb16681a
+
+It is currently not possible yet to use "memory-backend-memfd" on s390x
+with hugepages enabled. This problem is caused by qemu_maxrampagesize()
+not taking memory-backend-memfd objects into account yet, so the code
+in s390_memory_init() fails to enable the huge page support there via
+s390_set_max_pagesize(). Fix it by generalizing the code, so that it
+looks at qemu_ram_pagesize(memdev->mr.ram_block) instead of re-trying
+to get the information from the filesystem.

++Selecting kernels with the ``loadparm`` property
++------------------------------------------------
++
++The ``s390-ccw-virtio`` machine supports the so-called ``loadparm`` parameter
++which can be used to select the kernel on the disk of the guest that the
++s390-ccw bios should boot. When starting QEMU, it can be specified like this::
++
++ qemu-system-s390x -machine s390-ccw-virtio,loadparm=<string>
++
++The first way to use this parameter is to use the word ``PROMPT`` as the
++``<string>`` here. In that case the s390-ccw bios will show a list of
++installed kernels on the disk of the guest and ask the user to enter a number
++to chose which kernel should be booted -- similar to what can be achieved by
++specifying the ``-boot menu=on`` option when starting QEMU. Note that the menu
++list will only show the names of the installed kernels when using a DASD-like
++disk image with 4k byte sectors. On normal SCSI-style disks with 512-byte
++sectors, there is not enough space for the zipl loader on the disk to store
++the kernel names, so you only get a list without names here.
++
++The second way to use this parameter is to use a number in the range from 0
++to 31. The numbers that can be used here correspond to the numbers that are
++shown when using the ``PROMPT`` option, and the s390-ccw bios will then try
++to automatically boot the kernel that is associated with the given number.
++Note that ``0`` can be used to boot the default entry.

+RH-Commit: [19/41] 180c4c0ab4941a0bf366dc7f32ee035e03daa6c0
+
+There's no need to have two write functions. Let's rather have two
+functions that set the data for elf 32/64 and then write it in a
+common function.

+RH-Commit: [24/41] 74ef470f24d9d98093c4d63730a99474587033fd
+
+The iteration over the memblocks in dump_iterate() is hard to
+understand so it's about time to clean it up. Instead of manually
+grabbing the next memblock we can use QTAILQ_FOREACH to iterate over
+all memblocks.
+
+Additionally we move the calculation of the offset and length out by
+introducing and using the dump_filter_memblock_*() functions. These
+functions will later be used to cleanup other parts of dump.c.

+section_offset will later be used to store the offset to the section
+data which will be stored last. For now memory_offset is only needed
+to make section_offset look nicer.

+When s->shdr_num is 0 we'll add 0 bytes of section headers which is
+equivalent to not adding section headers but with the multiplication
+we can remove a if/else.

+the dump note functions from the opaque pointers to DumpState
+pointers.

+
+dump_calculate_size() sums up all the sizes of the guest memory
+blocks. Since we already have a function that calculates the size of a
+single memory block (dump_get_memblock_size()) we can simply iterate
+over the blocks and use the function instead of calculating the size
+ourselves.

+"filter_area_" prefix and make has_filter a function checking length > 0.

+get_start_block() returns the start address of the first memory block
+or -1.
+
+With the GuestPhysBlock iterator conversion we don't need to set the
+start address and can therefore remove that code and the "start"
+DumpState struct member. The only functionality left is the validation
+of the start block so it only makes sense to re-name the function to
+validate_start_block()

+RH-Commit: [32/41] e1a03e202e67764581e486f37e13e479200e5846
+
+Currently we're writing the NULL section header if we overflow the
+physical header number in the ELF header. But in the future we'll add
+custom section headers AND section data.
+
+To facilitate this we need to rearange section handling a bit. As with
+the other ELF headers we split the code into a prepare and a write
+step.

+
+Rewrite get_next_page() to work over non-aligned blocks. When it
+encounters non aligned addresses, it will try to fill a page provided by
+the caller.
+
+This solves a kdump crash with "tpm-crb-cmd" RAM memory region,
+qemu-kvm: ../dump/dump.c:1162: _Bool get_next_page(GuestPhysBlock **,
+uint64_t *, uint8_t **, DumpState *): Assertion `(block->target_start &
+~target_page_mask) == 0' failed.
+
+because:
+guest_phys_block_add_section: target_start=00000000fed40080 target_end=00000000fed41000: added (count: 4)

+
+The following patch is a major rewrite to get rid of the assert().

+ hw/display/qxl: Avoid buffer overrun in qxl_phys2virt (CVE-2022-4144)
+
+ Have qxl_get_check_slot_offset() return false if the requested
+ buffer size does not fit within the slot memory region.
+
+ Similarly qxl_phys2virt() now returns NULL in such case, and
+ qxl_dirty_one_surface() aborts.
+
+ This avoids buffer overrun in the host pointer returned by
+ memory_region_get_ram_ptr().
+
+ Fixes: CVE-2022-4144 (out-of-bounds read)

+
+ hw/display/qxl: Pass requested buffer size to qxl_phys2virt()
+
+ Currently qxl_phys2virt() doesn't check for buffer overrun.
+ In order to do so in the next commit, pass the buffer size
+ as argument.
+
+ For QXLCursor in qxl_render_cursor() -> qxl_cursor() we
+ verify the size of the chunked data ahead, checking we can
+ access 'sizeof(QXLCursor) + chunk->data_size' bytes.
+ Since in the SPICE_CURSOR_TYPE_MONO case the cursor is
+ assumed to fit in one chunk, no change are required.
+ In SPICE_CURSOR_TYPE_ALPHA the ahead read is handled in
+ qxl_unpack_chunks().

+RH-Commit: [2/2] 28a0086cb0e8be2535deafdd9115cadd7ff033f3
+
+Currently, when running 'qemu-system-s390x -M s390-ccw-virtio,help'
+the s390x-specific properties are not listed anymore. This happens
+because since commit d8fb7d0969 ("vl: switch -M parsing to keyval")
+the properties have to be defined at the class level and not at the
+instance level anymore. Fix it on s390x now, too, by moving the
+registration of the properties to the class level"
+
+Fixes: d8fb7d0969 ("vl: switch -M parsing to keyval")

+

+devices, so let's let these in. This will allow, for example, ISM
+devices to be passed through -- but only when interpretation is
+available and being used.

+RH-Commit: [7/41] 3a96e901e295bb9e0c530638c45b5da5d60c00bd
+
+If the ZPCI_OP ioctl reports that is is available and usable, then the
+underlying KVM host will enable load/store intepretation for any guest
+device without a SHM bit in the guest function handle. For a device that
+will be using interpretation support, ensure the guest function handle
+matches the host function handle; this value is re-checked every time the
+guest issues a SET PCI FN to enable the guest device as it is the only
+opportunity to reflect function handle changes.
+
+By default, unless interpret=off is specified, interpretation support will
+always be assumed and exploited if the necessary ioctl and features are
+available on the host kernel. When these are unavailable, we will silently
+revert to the interception model; this allows existing guest configurations
+to work unmodified on hosts with and without zPCI interpretation support,
+allowing QEMU to choose the best support model available.

+
+Let's use the reserved pool of simulated PCI groups to allow intercept
+devices to have separate groups from interpreted devices as some group
+values may be different. If we run out of simulated PCI groups, subsequent
+intercept devices just get the default group.
+Furthermore, if we encounter any PCI groups from hostdevs that are marked
+as simulated, let's just assign them to the default group to avoid
+conflicts between host simulated groups and our own simulated groups.

+
+The current default PCI group being used can technically collide with a
+real group ID passed from a hostdev. Let's instead use a group ID that
+comes from a special pool (0xF0-0xFF) that is architected to be reserved
+for simulated devices.

+RH-Commit: [41/41] 2731c2329276e76013e3b3df21e9743bc74edd2b
+
+Sometimes dumping a guest from the outside is the only way to get the
+data that is needed. This can be the case if a dumping mechanism like
+KDUMP hasn't been configured or data needs to be fetched at a specific
+point. Dumping a protected guest from the outside without help from
+fw/hw doesn't yield sufficient data to be useful. Hence we now
+introduce PV dump support.
+
+The PV dump support works by integrating the firmware into the dump
+process. New Ultravisor calls are used to initiate the dump process,
+dump cpu data, dump memory state and lastly complete the dump process.
+The UV calls are exposed by KVM via the new KVM_PV_DUMP command and
+its subcommands. The guest's data is fully encrypted and can only be
+decrypted by the entity that owns the customer communication key for
+the dumped guest. Also dumping needs to be allowed via a flag in the
+SE header.
+
+On the QEMU side of things we store the PV dump data in the newly
+introduced architecture ELF sections (storage state and completion
+data) and the cpu notes (for cpu dump data).
+
+Users can use the zgetdump tool to convert the encrypted QEMU dump to an
+unencrypted one.

+
+Under PV, the guest's TOD clock is under control of the ultravisor and the
+hypervisor cannot change it.
+
+With upcoming kernel changes[1], the Linux kernel will reject QEMU's
+request to adjust the guest's clock in this case, so don't attempt to set
+the clock.
+
+This avoids the following warning message on save/restore of a PV guest:
+
+warning: Unable to set KVM guest TOD clock: Operation not supported

+
+ target/arm/kvm: Retry KVM_CREATE_VM call if it fails EINTR
+
+ Occasionally the KVM_CREATE_VM ioctl can return EINTR, even though
+ there is no pending signal to be taken. In commit 94ccff13382055
+ we added a retry-on-EINTR loop to the KVM_CREATE_VM call in the
+ generic KVM code. Adopt the same approach for the use of the
+ ioctl in the Arm-specific KVM code (where we use it to create a
+ scratch VM for probing for various things).

+
+Storage key controlled protection is currently not honored when
+emulating instructions.
+If available, enable key protection for the MEM_OP ioctl, thereby
+enabling it for the s390_cpu_virt_mem_* functions, when using kvm.
+As a result, the emulation of the following instructions honors storage
+keys:
+
+* CLP
+ The Synch I/O CLP command would need special handling in order
+ to support storage keys, but is currently not supported.
+* CHSC
+ Performing commands asynchronously would require special
+ handling, but commands are currently always synchronous.
+* STSI
+* TSCH
+ Must (and does) not change channel if terminated due to
+ protection.
+* MSCH
+ Suppressed on protection, works because fetching instruction.
+* SSCH
+ Suppressed on protection, works because fetching instruction.
+* STSCH
+* STCRW
+ Suppressed on protection, this works because no partial store is
+ possible, because the operand cannot span multiple pages.
+* PCISTB
+* MPCIFC
+* STPCIFC

+ ui/vnc-clipboard: fix integer underflow in vnc_client_cut_text_ext
+
+ Extended ClientCutText messages start with a 4-byte header. If len < 4,
+ an integer underflow occurs in vnc_client_cut_text_ext. The result is
+ used to decompress data in a while loop in inflate_buffer, leading to
+ CPU consumption and denial of service. Prevent this by checking dlen in
+ protocol_client_msg.

+RH-Commit: [2/2] 264d3bdbbde985f16ed6f5a1786547c25fb8cc04
+
+Unlike most virtio features ACCESS_PLATFORM is considered mandatory by
+QEMU, i.e. the driver must accept it if offered by the device. The
+virtio specification says that the driver SHOULD accept the
+ACCESS_PLATFORM feature if offered, and that the device MAY fail to
+operate if ACCESS_PLATFORM was offered but not negotiated.
+
+While a SHOULD ain't exactly a MUST, we are certainly allowed to fail
+the device when the driver fences ACCESS_PLATFORM. With commit
+2943b53f68 ("virtio: force VIRTIO_F_IOMMU_PLATFORM") we already made the
+decision to do so whenever the get_dma_as() callback is implemented (by
+the bus), which in practice means for the entirety of virtio-pci.
+
+That means, if the device needs to translate I/O addresses, then
+ACCESS_PLATFORM is mandatory. The aforementioned commit tells us in the
+commit message that this is for security reasons. More precisely if we
+were to allow a less then trusted driver (e.g. an user-space driver, or
+a nested guest) to make the device bypass the IOMMU by not negotiating
+ACCESS_PLATFORM, then the guest kernel would have no ability to
+control/police (by programming the IOMMU) what pieces of guest memory
+the driver may manipulate using the device. Which would break security
+assumptions within the guest.
+
+If ACCESS_PLATFORM is offered not because we want the device to utilize
+an IOMMU and do address translation, but because the device does not
+have access to the entire guest RAM, and needs the driver to grant
+access to the bits it needs access to (e.g. confidential guest support),
+we still require the guest to have the corresponding logic and to accept
+ACCESS_PLATFORM. If the driver does not accept ACCESS_PLATFORM, then
+things are bound to go wrong, and we may see failures much less graceful
+than failing the device because the driver didn't negotiate
+ACCESS_PLATFORM.
+
+So let us make ACCESS_PLATFORM mandatory for the driver regardless
+of whether the get_dma_as() callback is implemented or not.

+RH-Commit: [1/2] d7edc7e3905a04644c9ff44b0d36122c72068e08
+
+The commit 04ceb61a40 ("virtio: Fail if iommu_platform is requested, but
+unsupported") claims to fail the device hotplug when iommu_platform
+is requested, but not supported by the (vhost) device. On the first
+glance the condition for detecting that situation looks perfect, but
+because a certain peculiarity of virtio_platform it ain't.
+
+In fact the aforementioned commit introduces a regression. It breaks
+virtio-fs support for Secure Execution, and most likely also for AMD SEV
+or any other confidential guest scenario that relies encrypted guest
+memory. The same also applies to any other vhost device that does not
+support _F_ACCESS_PLATFORM.
+
+The peculiarity is that iommu_platform and _F_ACCESS_PLATFORM collates
+"device can not access all of the guest RAM" and "iova != gpa, thus
+device needs to translate iova".
+
+Confidential guest technologies currently rely on the device/hypervisor
+offering _F_ACCESS_PLATFORM, so that, after the feature has been
+negotiated, the guest grants access to the portions of memory the
+device needs to see. So in for confidential guests, generally,
+_F_ACCESS_PLATFORM is about the restricted access to memory, but not
+about the addresses used being something else than guest physical
+addresses.
+
+This is the very reason for which commit f7ef7e6e3b ("vhost: correctly
+turn on VIRTIO_F_IOMMU_PLATFORM") fences _F_ACCESS_PLATFORM from the
+vhost device that does not need it, because on the vhost interface it
+only means "I/O address translation is needed".
+
+This patch takes inspiration from f7ef7e6e3b ("vhost: correctly turn on
+VIRTIO_F_IOMMU_PLATFORM"), and uses the same condition for detecting the
+situation when _F_ACCESS_PLATFORM is requested, but no I/O translation
+by the device, and thus no device capability is needed. In this
+situation claiming that the device does not support iommu_plattform=on
+is counter-productive. So let us stop doing that!

+RH-Commit: [1/1] da8795576acc7029044a801ef42676d66471a577
+
+The "%f" specifier in g_date_time_format() is only available in glib
+2.65.2 or later. If combined with older glib, the function returns null
+and the timestamp displayed as "(null)".
+
+For backward compatibility, g_date_time_get_microsecond should be used
+to retrieve subsecond.
+
+In this patch the g_date_time_format() leaves subsecond field as "%06d"
+and let next snprintf to format with g_date_time_get_microsecond.
