The free_device_compression_mode(iaa_device, device_mode) function frees
"device_mode" but it iss passed to iaa_compression_modes[i]->free() a few
lines later resulting in a use after free.
The good news is that, so far as I can tell, nothing implements the
->free() function and the use after free happens in dead code. But, with
this fix, when something does implement it, we'll be ready. :)

The QAT driver allows enabling SR-IOV VFs but does not allow them to be
disabled through a write to sysfs.
Disabling SR-IOV VFs can be only achieved by bringing down and up a
device using the attribute /sys/bus/pci/devices/<BDF>/qat/state.
The documentation for the sysfs attribute `sriov_numvfs` specifies
that "a userspace application wanting to disable the VFs would write a
zero to this file".
Add support for disabling SR-IOV VFs by writing '0' to the
'sriov_numvfs' attribute in sysfs.
Enabling or disabling SR-IOV always requires adf_dev_down() to be
called. This action subsequently leads to the deletion of the
ADF_KERNEL_SEC configuration section. The keys ADF_NUM_CY and ADF_NUM_DC
within that section must be set to '0', otherwise, the driver will
register into the Linux Crypto Framework. Because of this, the
configuration in the ADF_KERNEL_SEC section must be added before every
sriov_enable.

In the process of sending the ADF_PF2VF_MSGTYPE_RESTARTING message to
Virtual Functions (VFs), the Physical Function (PF) should set the
`vf->restarting` flag to true before dispatching the message.
This change is necessary to prevent a race condition where the handling
of the ADF_VF2PF_MSGTYPE_RESTARTING_COMPLETE message (which sets the
`vf->restarting` flag to false) runs immediately after the message is sent,
but before the flag is set to true.
Set the `vf->restarting` to true before sending the message
ADF_PF2VF_MSGTYPE_RESTARTING, if supported by the version of the
protocol and if the VF is started.

When the PFVF protocol was updated to support version 5, i.e.

updated without supporting the message RESTARTING_COMPLETE required for
such version.
Add support for the ADF_VF2PF_MSGTYPE_RESTARTING_COMPLETE message in the

The ADF_GENERAL_SEC configuration section contains values that must be
preserved during state transitions (down -> up, up -> down).
This patch modifies the logic in adf_dev_shutdown() to maintain all
key values within this section, rather than selectively saving and
restoring only the ADF_SERVICES_ENABLED attribute.
To achieve this, a new function has been introduced that deletes all
configuration sections except for the one specified by name.
This function is invoked during adf_dev_down(), with ADF_GENERAL_SEC
as the argument. Consequently, the adf_dev_shutdown_cache_cfg() function
has been removed as it is now redundant.
Additionally, this patch eliminates the cache_config parameter from
the adf_dev_down() function since ADF_GENERAL_SEC should always be
retained. This change does not cause any side effects because all
entries in the key-value store are cleared when a module is unloaded.

Pull kvm updates from Paolo Bonzini:
"ARM:
- Initial infrastructure for shadow stage-2 MMUs, as part of nested
virtualization enablement
- Support for userspace changes to the guest CTR_EL0 value, enabling
(in part) migration of VMs between heterogenous hardware
- Fixes + improvements to pKVM's FF-A proxy, adding support for v1.1
of the protocol
- FPSIMD/SVE support for nested, including merged trap configuration
and exception routing
- New command-line parameter to control the WFx trap behavior under
KVM
- Introduce kCFI hardening in the EL2 hypervisor
- Fixes + cleanups for handling presence/absence of FEAT_TCRX
- Miscellaneous fixes + documentation updates
LoongArch:
- Add paravirt steal time support
- Add support for KVM_DIRTY_LOG_INITIALLY_SET
- Add perf kvm-stat support for loongarch
RISC-V:
- Redirect AMO load/store access fault traps to guest
- perf kvm stat support
- Use guest files for IMSIC virtualization, when available
s390:
- Assortment of tiny fixes which are not time critical
x86:
- Fixes for Xen emulation
- Add a global struct to consolidate tracking of host values, e.g.
EFER
- Add KVM_CAP_X86_APIC_BUS_CYCLES_NS to allow configuring the
effective APIC bus frequency, because TDX
- Print the name of the APICv/AVIC inhibits in the relevant
tracepoint
- Clean up KVM's handling of vendor specific emulation to
consistently act on "compatible with Intel/AMD", versus checking
for a specific vendor
- Drop MTRR virtualization, and instead always honor guest PAT on
CPUs that support self-snoop
- Update to the newfangled Intel CPU FMS infrastructure
- Don't advertise IA32_PERF_GLOBAL_OVF_CTRL as an MSR-to-be-saved, as
it reads '0' and writes from userspace are ignored
- Misc cleanups
x86 - MMU:
- Small cleanups, renames and refactoring extracted from the upcoming
Intel TDX support
- Don't allocate kvm_mmu_page.shadowed_translation for shadow pages
that can't hold leafs SPTEs
- Unconditionally drop mmu_lock when allocating TDP MMU page tables
for eager page splitting, to avoid stalling vCPUs when splitting
huge pages
- Bug the VM instead of simply warning if KVM tries to split a SPTE
that is non-present or not-huge. KVM is guaranteed to end up in a
broken state because the callers fully expect a valid SPTE, it's
all but dangerous to let more MMU changes happen afterwards
x86 - AMD:
- Make per-CPU save_area allocations NUMA-aware
- Force sev_es_host_save_area() to be inlined to avoid calling into
an instrumentable function from noinstr code
- Base support for running SEV-SNP guests. API-wise, this includes a
new KVM_X86_SNP_VM type, encrypting/measure the initial image into
guest memory, and finalizing it before launching it. Internally,
there are some gmem/mmu hooks needed to prepare gmem-allocated
pages before mapping them into guest private memory ranges
This includes basic support for attestation guest requests, enough
to say that KVM supports the GHCB 2.0 specification
There is no support yet for loading into the firmware those signing
keys to be used for attestation requests, and therefore no need yet
for the host to provide certificate data for those keys.
To support fetching certificate data from userspace, a new KVM exit
type will be needed to handle fetching the certificate from
userspace.
An attempt to define a new KVM_EXIT_COCO / KVM_EXIT_COCO_REQ_CERTS
exit type to handle this was introduced in v1 of this patchset, but
is still being discussed by community, so for now this patchset
only implements a stub version of SNP Extended Guest Requests that
does not provide certificate data
x86 - Intel:
- Remove an unnecessary EPT TLB flush when enabling hardware
- Fix a series of bugs that cause KVM to fail to detect nested
pending posted interrupts as valid wake eents for a vCPU executing
HLT in L2 (with HLT-exiting disable by L1)
- KVM: x86: Suppress MMIO that is triggered during task switch
emulation
Explicitly suppress userspace emulated MMIO exits that are
triggered when emulating a task switch as KVM doesn't support
userspace MMIO during complex (multi-step) emulation
Silently ignoring the exit request can result in the
WARN_ON_ONCE(vcpu->mmio_needed) firing if KVM exits to userspace
for some other reason prior to purging mmio_needed
See commit 0dc902267cb3 ("KVM: x86: Suppress pending MMIO write
exits if emulator detects exception") for more details on KVM's
limitations with respect to emulated MMIO during complex emulator
flows
Generic:
- Rename the AS_UNMOVABLE flag that was introduced for KVM to
AS_INACCESSIBLE, because the special casing needed by these pages
is not due to just unmovability (and in fact they are only
unmovable because the CPU cannot access them)
- New ioctl to populate the KVM page tables in advance, which is
useful to mitigate KVM page faults during guest boot or after live
migration. The code will also be used by TDX, but (probably) not
through the ioctl
- Enable halt poll shrinking by default, as Intel found it to be a
clear win
- Setup empty IRQ routing when creating a VM to avoid having to
synchronize SRCU when creating a split IRQCHIP on x86
- Rework the sched_in/out() paths to replace kvm_arch_sched_in() with
a flag that arch code can use for hooking both sched_in() and
sched_out()
- Take the vCPU @id as an "unsigned long" instead of "u32" to avoid
truncating a bogus value from userspace, e.g. to help userspace
detect bugs
- Mark a vCPU as preempted if and only if it's scheduled out while in
the KVM_RUN loop, e.g. to avoid marking it preempted and thus
writing guest memory when retrieving guest state during live
migration blackout
Selftests:
- Remove dead code in the memslot modification stress test
- Treat "branch instructions retired" as supported on all AMD Family
17h+ CPUs
- Print the guest pseudo-RNG seed only when it changes, to avoid
spamming the log for tests that create lots of VMs
- Make the PMU counters test less flaky when counting LLC cache
misses by doing CLFLUSH{OPT} in every loop iteration"

When requesting an attestation report a guest is able to specify whether
it wants SNP firmware to sign the report using either a Versioned Chip
Endorsement Key (VCEK), which is derived from chip-unique secrets, or a
Versioned Loaded Endorsement Key (VLEK) which is obtained from an AMD
Key Derivation Service (KDS) and derived from seeds allocated to
enrolled cloud service providers (CSPs).
For VLEK keys, an SNP_VLEK_LOAD SNP firmware command is used to load
them into the system after obtaining them from the KDS. Add a
corresponding userspace interface so to allow the loading of VLEK keys
into the system.
See SEV-SNP Firmware ABI 1.54, SNP_VLEK_LOAD for more details.

The Allwinner H616 (and later) SoCs support more than 32 bits worth of
physical addresses. To accommodate the larger address space, the CE task
descriptor fields holding addresses are now encoded as "word addresses",
so take the actual address divided by four.
This is true for the fields within the descriptor, but also for the
descriptor base address, in the CE_TDA register.
Wrap all accesses to those fields in a function, which will do the
required division if needed. For now this in unused, so there should be
no change in behaviour.

Embedding net_device into structures prohibits the usage of flexible
arrays in the net_device structure. For more details, see the discussion
at [1].
Un-embed the net_devices from struct caam_qi_pcpu_priv by converting them
into pointers, and allocating them dynamically. Use the leverage
alloc_netdev_dummy() to allocate the net_device object at
caam_qi_init().
The free of the device occurs at caam_qi_shutdown().

If caam module is built without OF support, the compiler returns the
following warning:
drivers/crypto/caam/ctrl.c:83:34: warning: 'imx8m_machine_match' defined but not used [-Wunused-const-variable=]
imx8m_machine_match is only referenced by of_match_node(), which is set
to NULL if CONFIG_OF is not set, as of commit 5762c20593b6b ("dt: Add
empty of_match_node() macro"):
#define of_match_node(_matches, _node) NULL
Do not create imx8m_machine_match if CONFIG_OF is not set.

Now that the driver core allows for struct class to be in read-only
memory, we should make all 'class' structures declared at build time
placing them into read-only memory, instead of having to be dynamically
allocated at runtime.

When the vf is enabled, the value of vfs_num must be assigned
after the VF configuration is complete. Otherwise, the device
may be accessed before the virtual configuration is complete,
causing an error.
When the vf is disabled, clear vfs_num and execute
qm_pm_put_sync before hisi_qm_sriov_disable is return.
Otherwise, if qm_clear_vft_config fails, users may access the

The finalize operation in interrupt mode produce a produces a spinlock
recursion warning. The reason is the fact that BH must be disabled
during this process.

Use DMA when buffer are aligned and with expected size.
If buffer are correctly aligned and bigger than 1KB we have some
performance gain:
With DMA enable:
$ openssl speed -evp aes-256-cbc -engine afalg -elapsed
The 'numbers' are in 1000s of bytes per second processed.
type 16 bytes 64 bytes 256 bytes 1024 bytes 8192 bytes 16384 bytes
aes-256-cbc 120.02k 406.78k 1588.82k 5873.32k 26020.52k 34258.94k
Without DMA:
$ openssl speed -evp aes-256-cbc -engine afalg -elapsed
The 'numbers' are in 1000s of bytes per second processed.
type 16 bytes 64 bytes 256 bytes 1024 bytes 8192 bytes 16384 bytes
