This release adds SM4 encryption support, contributed by Tianjia Zhang.
SM4 is a Chinese block cipher that is an alternative to AES.
I recommend against using SM4, but (according to Tianjia) some people
are being required to use it. Since SM4 has been turning up in many
other places (crypto API, wireless, TLS, OpenSSL, ARMv8 CPUs, etc.), it
hasn't been very controversial, and some people have to use it, I don't
think it would be fair for me to reject this optional feature.
Besides the above, there are a couple cleanups.

Pull cxl updates from Dan Williams:
"Compute Express Link (CXL) updates for 6.2.
While it may seem backwards, the CXL update this time around includes
some focus on CXL 1.x enabling where the work to date had been with
CXL 2.0 (VH topologies) in mind.
First generation CXL can mostly be supported via BIOS, similar to DDR,
however it became clear there are use cases for OS native CXL error
handling and some CXL 3.0 endpoint features can be deployed on CXL 1.x
hosts (Restricted CXL Host (RCH) topologies). So, this update brings
RCH topologies into the Linux CXL device model.
In support of the ongoing CXL 2.0+ enabling two new core kernel
facilities are added.
One is the ability for the kernel to flag collisions between userspace
access to PCI configuration registers and kernel accesses. This is
brought on by the PCIe Data-Object-Exchange (DOE) facility, a hardware
mailbox over config-cycles.
The other is a cpu_cache_invalidate_memregion() API that maps to
wbinvd_on_all_cpus() on x86. To prevent abuse it is disabled in guest
VMs and architectures that do not support it yet. The CXL paths that
need it, dynamic memory region creation and security commands (erase /
unlock), are disabled when it is not present.
As for the CXL 2.0+ this cycle the subsystem gains support Persistent
Memory Security commands, error handling in response to PCIe AER
notifications, and support for the "XOR" host bridge interleave
algorithm.
Summary:
- Add the cpu_cache_invalidate_memregion() API for cache flushing in
response to physical memory reconfiguration, or memory-side data
invalidation from operations like secure erase or memory-device
unlock.
- Add a facility for the kernel to warn about collisions between
kernel and userspace access to PCI configuration registers
- Add support for Restricted CXL Host (RCH) topologies (formerly CXL
1.1)
- Add handling and reporting of CXL errors reported via the PCIe AER
mechanism
- Add support for CXL Persistent Memory Security commands
- Add support for the "XOR" algorithm for CXL host bridge interleave
- Rework / simplify CXL to NVDIMM interactions

CXL PMEM security operations are routed through the NVDIMM sysfs
interface. For this reason the corresponding commands are marked
"exclusive" to preclude collisions between the ioctl ABI and the sysfs
ABI. However, a better way to preclude that collision is to simply
remove the ioctl ABI (command-id definitions) for those operations.
Now that cxl_internal_send_cmd() (formerly cxl_mbox_send_cmd()) no
longer needs to talk the cxl_mem_commands array, all of the uapi
definitions for the security commands can be dropped.
These never appeared in a released kernel, so no regression risk.

These old unused definitions were originally left around to prevent the
same mode numbers from being reused. However, we've now decided to
reuse the mode numbers anyway. So let's completely remove these old
unused definitions to avoid confusion. There is no reason for any code
to be using these constants in any way; and indeed, Debian Code Search
shows no uses of them (other than in copies or translations of the
header). So this should be perfectly safe.

TDX guest driver exposes IOCTL interfaces to service TDX guest
user-specific requests. Currently, it is only used to allow the user to
get the TDREPORT to support TDX attestation.
Details about the TDX attestation process are documented in
Documentation/x86/tdx.rst, and the IOCTL details are documented in
Documentation/virt/coco/tdx-guest.rst.
Operations like getting TDREPORT involves sending a blob of data as
input and getting another blob of data as output. It was considered
to use a sysfs interface for this, but it doesn't fit well into the
standard sysfs model for configuring values. It would be possible to
do read/write on files, but it would need multiple file descriptors,
which would be somewhat messy. IOCTLs seem to be the best fitting
and simplest model for this use case. The AMD sev-guest driver also
uses the IOCTL interface to support attestation.

This is because we try to copy the whole ip/ip6 address to the flow_key,
while we only point the to ip/ip6 saddr. Note that since these are UAPI
headers, __struct_group() is used to avoid the compiler warnings.

The PCIE Data Object Exchange (DOE) mailbox is a protocol run over
configuration cycles. It assumes one initiator at a time. While the
kernel has control of the mailbox user space writes could interfere with
the kernel access.
Mark DOE mailbox config space exclusive when iterated by the CXL driver.

While the fix is trivial and I can't imagine it causing a problem in a

that there is some system out there which is relying on some wonky
unexpected behavior which this patch could break; *if* it does break,
IMO it's better that to happen in a minor or -rcX release and not in a

__le32 and __le64 types aren't portable and are not available on
FreeBSD (which uses the same uAPI).
Instead of attempting to always output little endian, just use native
endianness in the dumps. Tools can detect the endianness in use by
looking at the 'magic' field, but equally we don't expect big-endian to
be used with Mali (there are no known implementations out there).

The two structs internal to struct panfrost_dump_object_header were
named, but sadly that is incompatible with C++, causing an error: "an
anonymous union may only have public non-static data members".
However nothing refers to struct pan_reg_hdr and struct pan_bomap_hdr
and there's no need to export these definitions, so lets drop them. This
fixes the C++ build error with the minimum change in userspace API.

When the idxd_user_drv driver is bound to a Work Queue (WQ) device
without IOMMU or with IOMMU Passthrough without Shared Virtual
Addressing (SVA), the application gains direct access to physical
memory via the device by programming physical address to a submitted
descriptor. This allows direct userspace read and write access to
arbitrary physical memory. This is inconsistent with the security
goals of a good kernel API.
Unlike vfio_pci driver, the IDXD char device driver does not provide any
ways to pin user pages and translate the address from user VA to IOVA or
PA without IOMMU SVA. Therefore the application has no way to instruct the
device to perform DMA function. This makes the char device not usable for
normal application usage.
Since user type WQ without SVA cannot be used for normal application usage
and presents the security issue, bind idxd_user_drv driver and enable user
type WQ only when SVA is enabled (i.e. user PASID is enabled).

- Prune private items from vfio_pci_core.h to a new internal header,
fix missed function rename, and refactor vfio-pci interrupt defines.
(Jason Gunthorpe)
- Create consistent naming and handling of ioctls with a function per
ioctl for vfio-pci and vfio group handling, use proper type args
where available. (Jason Gunthorpe)
- Implement a set of low power device feature ioctls allowing userspace
to make use of power states such as D3cold where supported.
(Abhishek Sahu)
- Remove device counter on vfio groups, which had restricted the page
pinning interface to singleton groups to account for limitations in
the type1 IOMMU backend. Document usage as limited to emulated IOMMU
devices, ie. traditional mdev devices where this restriction is
consistent. (Jason Gunthorpe)
- Correct function prefix in hisi_acc driver incurred during previous
refactoring. (Shameer Kolothum)
- Correct typo and remove redundant warning triggers in vfio-fsl driver.
(Christophe JAILLET)
- Introduce device level DMA dirty tracking uAPI and implementation in
the mlx5 variant driver (Yishai Hadas & Joao Martins)
- Move much of the vfio_device life cycle management into vfio core,
simplifying and avoiding duplication across drivers. This also
facilitates adding a struct device to vfio_device which begins the
introduction of device rather than group level user support and fills
a gap allowing userspace identify devices as vfio capable without
implicit knowledge of the driver. (Kevin Tian & Yi Liu)
- Split vfio container handling to a separate file, creating a more
well defined API between the core and container code, masking IOMMU
backend implementation from the core, allowing for an easier future
transition to an iommufd based implementation of the same.
(Jason Gunthorpe)
- Attempt to resolve race accessing the iommu_group for a device
between vfio releasing DMA ownership and removal of the device from
the IOMMU driver. Follow-up with support to allow vfio_group to
exist with NULL iommu_group pointer to support existing userspace
use cases of holding the group file open. (Jason Gunthorpe)
- Fix error code and hi/lo register manipulation issues in the hisi_acc
variant driver, along with various code cleanups. (Longfang Liu)
- Fix a prior regression in GVT-g group teardown, resulting in
unreleased resources. (Jason Gunthorpe)
- A significant cleanup and simplification of the mdev interface,
consolidating much of the open coded per driver sysfs interface
support into the mdev core. (Christoph Hellwig)
- Simplification of tracking and locking around vfio_groups that
fall out from previous refactoring. (Jason Gunthorpe)
- Replace trivial open coded f_ops tests with new helper.
