2c9b351240 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
 
 ONE_REG support for the Zimop, Zcmop, Zca, Zcf, Zcd, Zcb and Zawrs ISA
 extensions is coming through the RISC-V tree.
 
 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.

332d2c1d71 crypto: ccp: Add the SNP_VLEK_LOAD command 
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.

dd52b5eeb0 crypto: mxs-dcp - Ensure payload is zero when using key slot 
We could leak stack memory through the payload field when running
AES with a key from one of the hardware's key slots. Fix this by
ensuring the payload field is set to 0 in such cases.

This does not affect the common use case when the key is supplied
from main memory via the descriptor payload.

f0622894c5 crypto: qat - fix unintentional re-enabling of error interrupts 
The logic that detects pending VF2PF interrupts unintentionally clears
the section of the error mask register(s) not related to VF2PF.
This might cause interrupts unrelated to VF2PF, reported through
errsou3 and errsou5, to be reported again after the execution
of the function disable_pending_vf2pf_interrupts() in dh895xcc
and GEN2 devices.

Fix by updating only section of errmsk3 and errmsk5 related to VF2PF.

The crypto engine in the Allwinner H616 is very similar to the H6, but
needs the base address for the task descriptor and the addresses within
it to be expressed in words, not in bytes.

Add a new variant struct entry for the H616, and set the new flag to
mark the use of 34 bit addresses. Also the internal 32K oscillator is
required for TRNG operation, so specify all four clocks.

e0740bee6c crypto: sun8i-ce - wrap accesses to descriptor address fields 
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.

Currently, the reg is queried based on the fixed address offset
array. When the number of accelerator cores changes, the system
can not flexibly respond to the change.

Therefore, the reg to be queried is calculated based on the

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

Otherwise, if qm_clear_vft_config fails, users may access the

d3b17c6d9d crypto: qat - Fix ADF_DEV_RESET_SYNC memory leak 
Using completion_done to determine whether the caller has gone
away only works after a complete call.  Furthermore it's still
possible that the caller has not yet called wait_for_completion,
resulting in another potential UAF.

Fix this by making the caller use cancel_work_sync and then freeing
the memory safely.

Linus Torvalds
1b294a1f35 Networking changes for 6.10. 
Core & protocols
 ----------------
 
  - Complete rework of garbage collection of AF_UNIX sockets.
    AF_UNIX is prone to forming reference count cycles due to fd passing
    functionality. New method based on Tarjan's Strongly Connected Components
    algorithm should be both faster and remove a lot of workarounds
    we accumulated over the years.
 
  - Add TCP fraglist GRO support, allowing chaining multiple TCP packets
    and forwarding them together. Useful for small switches / routers which
    lack basic checksum offload in some scenarios (e.g. PPPoE).
 
  - Support using SMP threads for handling packet backlog i.e. packet
    processing from software interfaces and old drivers which don't
    use NAPI. This helps move the processing out of the softirq jumble.
 
  - Continue work of converting from rtnl lock to RCU protection.
    Don't require rtnl lock when reading: IPv6 routing FIB, IPv6 address
    labels, netdev threaded NAPI sysfs files, bonding driver's sysfs files,
    MPLS devconf, IPv4 FIB rules, netns IDs, tcp metrics, TC Qdiscs,
    neighbor entries, ARP entries via ioctl(SIOCGARP), a lot of the link
    information available via rtnetlink.
 
  - Small optimizations from Eric to UDP wake up handling, memory accounting,
    RPS/RFS implementation, TCP packet sizing etc.
 
  - Allow direct page recycling in the bulk API used by XDP, for +2% PPS.
 
  - Support peek with an offset on TCP sockets.
 
  - Add MPTCP APIs for querying last time packets were received/sent/acked,
    and whether MPTCP "upgrade" succeeded on a TCP socket.
 
  - Add intra-node communication shortcut to improve SMC performance.
 
  - Add IPv6 (and IPv{4,6}-over-IPv{4,6}) support to the GTP protocol driver.
 
  - Add HSR-SAN (RedBOX) mode of operation to the HSR protocol driver.
 
  - Add reset reasons for tracing what caused a TCP reset to be sent.
 
  - Introduce direction attribute for xfrm (IPSec) states.
    State can be used either for input or output packet processing.
 
 Things we sprinkled into general kernel code
 --------------------------------------------
 
  - Add bitmap_{read,write}(), bitmap_size(), expose BYTES_TO_BITS().
    This required touch-ups and renaming of a few existing users.
 
  - Add Endian-dependent __counted_by_{le,be} annotations.
 
  - Make building selftests "quieter" by printing summaries like
    "CC object.o" rather than full commands with all the arguments.
 
 Netfilter
 ---------
 
  - Use GFP_KERNEL to clone elements, to deal better with OOM situations
    and avoid failures in the .commit step.
 
 BPF
 ---
 
  - Add eBPF JIT for ARCv2 CPUs.
 
  - Support attaching kprobe BPF programs through kprobe_multi link in
    a session mode, meaning, a BPF program is attached to both function entry
    and return, the entry program can decide if the return program gets
    executed and the entry program can share u64 cookie value with return
    program. "Session mode" is a common use-case for tetragon and bpftrace.
 
  - Add the ability to specify and retrieve BPF cookie for raw tracepoint
    programs in order to ease migration from classic to raw tracepoints.
 
  - Add an internal-only BPF per-CPU instruction for resolving per-CPU
    memory addresses and implement support in x86, ARM64 and RISC-V JITs.
    This allows inlining functions which need to access per-CPU state.
 
  - Optimize x86 BPF JIT's emit_mov_imm64, and add support for various
    atomics in bpf_arena which can be JITed as a single x86 instruction.
    Support BPF arena on ARM64.
 
  - Add a new bpf_wq API for deferring events and refactor process-context
    bpf_timer code to keep common code where possible.
 
  - Harden the BPF verifier's and/or/xor value tracking.
 
  - Introduce crypto kfuncs to let BPF programs call kernel crypto APIs.
 
  - Support bpf_tail_call_static() helper for BPF programs with GCC 13.
 
  - Add bpf_preempt_{disable,enable}() kfuncs in order to allow a BPF
    program to have code sections where preemption is disabled.
 
 Driver API
 ----------
 
  - Skip software TC processing completely if all installed rules are
    marked as HW-only, instead of checking the HW-only flag rule by rule.
 
  - Add support for configuring PoE (Power over Ethernet), similar to
    the already existing support for PoDL (Power over Data Line) config.
 
  - Initial bits of a queue control API, for now allowing a single queue
    to be reset without disturbing packet flow to other queues.
 
  - Common (ethtool) statistics for hardware timestamping.
 
 Tests and tooling
 -----------------
 
  - Remove the need to create a config file to run the net forwarding tests
    so that a naive "make run_tests" can exercise them.
 
  - Define a method of writing tests which require an external endpoint
    to communicate with (to send/receive data towards the test machine).
    Add a few such tests.
 
  - Create a shared code library for writing Python tests. Expose the YAML
    Netlink library from tools/ to the tests for easy Netlink access.
 
  - Move netfilter tests under net/, extend them, separate performance tests
    from correctness tests, and iron out issues found by running them
    "on every commit".
 
  - Refactor BPF selftests to use common network helpers.
 
  - Further work filling in YAML definitions of Netlink messages for:
    nftables, team driver, bonding interfaces, vlan interfaces, VF info,
    TC u32 mark, TC police action.
 
  - Teach Python YAML Netlink to decode attribute policies.
 
  - Extend the definition of the "indexed array" construct in the specs
    to cover arrays of scalars rather than just nests.
 
  - Add hyperlinks between definitions in generated Netlink docs.
 
 Drivers
 -------
 
  - Make sure unsupported flower control flags are rejected by drivers,
    and make more drivers report errors directly to the application rather
    than dmesg (large number of driver changes from Asbjørn Sloth Tønnesen).
 
  - Ethernet high-speed NICs:

     This required touch-ups and renaming of a few existing users.

   - Add Endian-dependent __counted_by_{le,be} annotations.

   - Make building selftests "quieter" by printing summaries like
     "CC object.o" rather than full commands with all the arguments.

  Netfilter:

   - Use GFP_KERNEL to clone elements, to deal better with OOM
     situations and avoid failures in the .commit step.

  BPF:

   - Add eBPF JIT for ARCv2 CPUs.

   - Support attaching kprobe BPF programs through kprobe_multi link in
     a session mode, meaning, a BPF program is attached to both function
     entry and return, the entry program can decide if the return
     program gets executed and the entry program can share u64 cookie
     value with return program. "Session mode" is a common use-case for
     tetragon and bpftrace.

   - Add the ability to specify and retrieve BPF cookie for raw
     tracepoint programs in order to ease migration from classic to raw
     tracepoints.

   - Add an internal-only BPF per-CPU instruction for resolving per-CPU
     memory addresses and implement support in x86, ARM64 and RISC-V
     JITs. This allows inlining functions which need to access per-CPU
     state.

   - Optimize x86 BPF JIT's emit_mov_imm64, and add support for various
     atomics in bpf_arena which can be JITed as a single x86
     instruction. Support BPF arena on ARM64.

   - Add a new bpf_wq API for deferring events and refactor
     process-context bpf_timer code to keep common code where possible.

   - Harden the BPF verifier's and/or/xor value tracking.

   - Introduce crypto kfuncs to let BPF programs call kernel crypto
     APIs.

   - Support bpf_tail_call_static() helper for BPF programs with GCC 13.

   - Add bpf_preempt_{disable,enable}() kfuncs in order to allow a BPF
     program to have code sections where preemption is disabled.

  Driver API:

   - Skip software TC processing completely if all installed rules are
     marked as HW-only, instead of checking the HW-only flag rule by
     rule.

   - Add support for configuring PoE (Power over Ethernet), similar to
     the already existing support for PoDL (Power over Data Line)
     config.

   - Initial bits of a queue control API, for now allowing a single
     queue to be reset without disturbing packet flow to other queues.

   - Common (ethtool) statistics for hardware timestamping.

  Tests and tooling:

   - Remove the need to create a config file to run the net forwarding
     tests so that a naive "make run_tests" can exercise them.

   - Define a method of writing tests which require an external endpoint
     to communicate with (to send/receive data towards the test
     machine). Add a few such tests.

   - Create a shared code library for writing Python tests. Expose the
     YAML Netlink library from tools/ to the tests for easy Netlink
     access.

   - Move netfilter tests under net/, extend them, separate performance
     tests from correctness tests, and iron out issues found by running
     them "on every commit".

   - Refactor BPF selftests to use common network helpers.

   - Further work filling in YAML definitions of Netlink messages for:
     nftables, team driver, bonding interfaces, vlan interfaces, VF
     info, TC u32 mark, TC police action.

   - Teach Python YAML Netlink to decode attribute policies.

   - Extend the definition of the "indexed array" construct in the specs
     to cover arrays of scalars rather than just nests.

   - Add hyperlinks between definitions in generated Netlink docs.

  Drivers:

   - Make sure unsupported flower control flags are rejected by drivers,
     and make more drivers report errors directly to the application
     rather than dmesg (large number of driver changes from Asbjørn
     Sloth Tønnesen).
