70a663205d Probes updates for v6.10: 
- tracing/probes: Adding new pseudo-types %pd and %pD support for dumping
   dentry name from 'struct dentry *' and file name from 'struct file *'.
 
 - uprobes: Some performance optimizations have been done.
  . Speed up the BPF uprobe event by delaying the fetching of the uprobe
    event arguments that are not used in BPF.
  . Avoid locking by speculatively checking whether uprobe event is valid.
  . Reduce lock contention by using read/write_lock instead of spinlock for
    uprobe list operation. This improved BPF uprobe benchmark result 43% on
    average.
 
 - rethook: Removes non-fatal warning messages when tracing stack from BPF
   and skip rcu_is_watching() validation in rethook if possible.
 
 - objpool: Optimizing objpool (which is used by kretprobes and fprobe as
   rethook backend storage) by inlining functions and avoid caching nr_cpu_ids
   because it is a const value.
 
 - fprobe: Add entry/exit callbacks types (code cleanup)
 - kprobes: Check ftrace was killed in kprobes if it uses ftrace.

b426433c03 * MTD 
Simon Glass wanted to support binman's output properties in order to
 check their validity using the binding checks and proposed changes with
 the missing properties as well as a binman compatible.
 
 Krzysztof Kozlowski on his side shared a new yaml for describing
 Samsung's OneNAND interface.
 
 The interface with NVMEM has also been slightly improved/fixed,
 especially now that OTP are also supported in the NAND subsystem.
 
 Along with these changes, small cleanups have also been contributed
 around ID tables, structure sizes, arithmetic checks and comments.
 
 * Raw NAND subsystem
 
 Two small fixes, one in the Hynix vendor code for properly returning an
 error which might have been ignored and another in the Davinci driver to
 properly synchronize the controller with the gpio domain.
 
 * SPI NOR subsystem
 
 SPI NOR now uses div_u64() instead of div64_u64() in places where the
 divisor is 32 bits. Many 32 bit architectures can optimize this variant
 better than a full 64 bit divide.

de6fef50ea cgroup: Changes for v6.10 
- The locking around cpuset hotplug processing has always been a bit of mess
   which was worked around by making hotplug processing asynchronous. The
   asynchronity isn't great and led to other issues. We tried to make the
   behavior synchronous a while ago but that led to lockdep splats. Waiman
   took another stab at cleaning up and making it synchronous. The patch has
   been in -next for well over a month and there haven't been any complaints,
   so fingers crossed.
 
 - Tracepoints added to help understanding rstat lock contentions.
 
 - A bunch of minor changes - doc updates, code cleanups and selftests.

f4b0c4b508 ARM: 
* Move a lot of state that was previously stored on a per vcpu
   basis into a per-CPU area, because it is only pertinent to the
   host while the vcpu is loaded. This results in better state
   tracking, and a smaller vcpu structure.
 
 * Add full handling of the ERET/ERETAA/ERETAB instructions in
   nested virtualisation. The last two instructions also require
   emulating part of the pointer authentication extension.
   As a result, the trap handling of pointer authentication has
   been greatly simplified.
 
 * Turn the global (and not very scalable) LPI translation cache
   into a per-ITS, scalable cache, making non directly injected
   LPIs much cheaper to make visible to the vcpu.
 
 * A batch of pKVM patches, mostly fixes and cleanups, as the
   upstreaming process seems to be resuming. Fingers crossed!
 
 * Allocate PPIs and SGIs outside of the vcpu structure, allowing
   for smaller EL2 mapping and some flexibility in implementing
   more or less than 32 private IRQs.
 
 * Purge stale mpidr_data if a vcpu is created after the MPIDR
   map has been created.
 
 * Preserve vcpu-specific ID registers across a vcpu reset.
 
 * Various minor cleanups and improvements.
 
 LoongArch:
 
 * Add ParaVirt IPI support.
 
 * Add software breakpoint support.
 
 * Add mmio trace events support.
 
 RISC-V:
 
 * Support guest breakpoints using ebreak
 
 * Introduce per-VCPU mp_state_lock and reset_cntx_lock
 
 * Virtualize SBI PMU snapshot and counter overflow interrupts
 
 * New selftests for SBI PMU and Guest ebreak
 
 * Some preparatory work for both TDX and SNP page fault handling.
   This also cleans up the page fault path, so that the priorities
   of various kinds of fauls (private page, no memory, write
   to read-only slot, etc.) are easier to follow.
 
 x86:
 
 * Minimize amount of time that shadow PTEs remain in the special
   REMOVED_SPTE state.  This is a state where the mmu_lock is held for
   reading but concurrent accesses to the PTE have to spin; shortening
   its use allows other vCPUs to repopulate the zapped region while
   the zapper finishes tearing down the old, defunct page tables.
 
 * Advertise the max mappable GPA in the "guest MAXPHYADDR" CPUID field,
   which is defined by hardware but left for software use.  This lets KVM
   communicate its inability to map GPAs that set bits 51:48 on hosts
   without 5-level nested page tables.  Guest firmware is expected to
   use the information when mapping BARs; this avoids that they end up at
   a legal, but unmappable, GPA.
 
 * Fixed a bug where KVM would not reject accesses to MSR that aren't
   supposed to exist given the vCPU model and/or KVM configuration.
 
 * As usual, a bunch of code cleanups.
 
 x86 (AMD):
 
 * Implement a new and improved API to initialize SEV and SEV-ES VMs, which
   will also be extendable to SEV-SNP.  The new API specifies the desired
   encryption in KVM_CREATE_VM and then separately initializes the VM.
   The new API also allows customizing the desired set of VMSA features;
   the features affect the measurement of the VM's initial state, and
   therefore enabling them cannot be done tout court by the hypervisor.
 
   While at it, the new API includes two bugfixes that couldn't be
   applied to the old one without a flag day in userspace or without
   affecting the initial measurement.  When a SEV-ES VM is created with
   the new VM type, KVM_GET_REGS/KVM_SET_REGS and friends are
   rejected once the VMSA has been encrypted.  Also, the FPU and AVX
   state will be synchronized and encrypted too.
 
 * Support for GHCB version 2 as applicable to SEV-ES guests.  This, once
   more, is only accessible when using the new KVM_SEV_INIT2 flow for
   initialization of SEV-ES VMs.
 
 x86 (Intel):
 
 * An initial bunch of prerequisite patches for Intel TDX were merged.
   They generally don't do anything interesting.  The only somewhat user
   visible change is a new debugging mode that checks that KVM's MMU
   never triggers a #VE virtualization exception in the guest.
 
 * Clear vmcs.EXIT_QUALIFICATION when synthesizing an EPT Misconfig VM-Exit to
   L1, as per the SDM.
 
 Generic:

Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm

Pull KVM updates from Paolo Bonzini:
 "ARM:

   - Move a lot of state that was previously stored on a per vcpu basis
     into a per-CPU area, because it is only pertinent to the host while
     the vcpu is loaded. This results in better state tracking, and a
     smaller vcpu structure.

   - Add full handling of the ERET/ERETAA/ERETAB instructions in nested
     virtualisation. The last two instructions also require emulating
     part of the pointer authentication extension. As a result, the trap
     handling of pointer authentication has been greatly simplified.

   - Turn the global (and not very scalable) LPI translation cache into
     a per-ITS, scalable cache, making non directly injected LPIs much
     cheaper to make visible to the vcpu.

   - A batch of pKVM patches, mostly fixes and cleanups, as the
     upstreaming process seems to be resuming. Fingers crossed!

   - Allocate PPIs and SGIs outside of the vcpu structure, allowing for
     smaller EL2 mapping and some flexibility in implementing more or
     less than 32 private IRQs.

   - Purge stale mpidr_data if a vcpu is created after the MPIDR map has
     been created.

   - Preserve vcpu-specific ID registers across a vcpu reset.

   - Various minor cleanups and improvements.

  LoongArch:

   - Add ParaVirt IPI support

   - Add software breakpoint support

   - Add mmio trace events support

  RISC-V:

   - Support guest breakpoints using ebreak

   - Introduce per-VCPU mp_state_lock and reset_cntx_lock

   - Virtualize SBI PMU snapshot and counter overflow interrupts

   - New selftests for SBI PMU and Guest ebreak

   - Some preparatory work for both TDX and SNP page fault handling.

     This also cleans up the page fault path, so that the priorities of
     various kinds of fauls (private page, no memory, write to read-only
     slot, etc.) are easier to follow.

  x86:

   - Minimize amount of time that shadow PTEs remain in the special
     REMOVED_SPTE state.

     This is a state where the mmu_lock is held for reading but
     concurrent accesses to the PTE have to spin; shortening its use
     allows other vCPUs to repopulate the zapped region while the zapper
     finishes tearing down the old, defunct page tables.

   - Advertise the max mappable GPA in the "guest MAXPHYADDR" CPUID
     field, which is defined by hardware but left for software use.

     This lets KVM communicate its inability to map GPAs that set bits
     51:48 on hosts without 5-level nested page tables. Guest firmware
     is expected to use the information when mapping BARs; this avoids
     that they end up at a legal, but unmappable, GPA.

   - Fixed a bug where KVM would not reject accesses to MSR that aren't
     supposed to exist given the vCPU model and/or KVM configuration.

   - As usual, a bunch of code cleanups.

  x86 (AMD):

   - Implement a new and improved API to initialize SEV and SEV-ES VMs,
     which will also be extendable to SEV-SNP.

     The new API specifies the desired encryption in KVM_CREATE_VM and
     then separately initializes the VM. The new API also allows
     customizing the desired set of VMSA features; the features affect
     the measurement of the VM's initial state, and therefore enabling
     them cannot be done tout court by the hypervisor.

     While at it, the new API includes two bugfixes that couldn't be
     applied to the old one without a flag day in userspace or without
     affecting the initial measurement. When a SEV-ES VM is created with
     the new VM type, KVM_GET_REGS/KVM_SET_REGS and friends are rejected
     once the VMSA has been encrypted. Also, the FPU and AVX state will
     be synchronized and encrypted too.

   - Support for GHCB version 2 as applicable to SEV-ES guests.

     This, once more, is only accessible when using the new
     KVM_SEV_INIT2 flow for initialization of SEV-ES VMs.

  x86 (Intel):

   - An initial bunch of prerequisite patches for Intel TDX were merged.

     They generally don't do anything interesting. The only somewhat
     user visible change is a new debugging mode that checks that KVM's
     MMU never triggers a #VE virtualization exception in the guest.

   - Clear vmcs.EXIT_QUALIFICATION when synthesizing an EPT Misconfig
     VM-Exit to L1, as per the SDM.

  Generic:

   - Use vfree() instead of kvfree() for allocations that always use
     vcalloc() or __vcalloc().

   - Remove .change_pte() MMU notifier - the changes to non-KVM code are
     small and Andrew Morton asked that I also take those through the
     KVM tree.

     The callback was only ever implemented by KVM (which was also the
     original user of MMU notifiers) but it had been nonfunctional ever
     since calls to set_pte_at_notify were wrapped with
     invalidate_range_start and invalidate_range_end... in 2012.

  Selftests:

   - Enhance the demand paging test to allow for better reporting and
     stressing of UFFD performance.

   - Convert the steal time test to generate TAP-friendly output.

   - Fix a flaky false positive in the xen_shinfo_test due to comparing
     elapsed time across two different clock domains.

   - Skip the MONITOR/MWAIT test if the host doesn't actually support
     MWAIT.

   - Avoid unnecessary use of "sudo" in the NX hugepage test wrapper
     shell script, to play nice with running in a minimal userspace
     environment.

   - Allow skipping the RSEQ test's sanity check that the vCPU was able
     to complete a reasonable number of KVM_RUNs, as the assert can fail
     on a completely valid setup.

     If the test is run on a large-ish system that is otherwise idle,
     and the test isn't affined to a low-ish number of CPUs, the vCPU
     task can be repeatedly migrated to CPUs that are in deep sleep
     states, which results in the vCPU having very little net runtime
     before the next migration due to high wakeup latencies.

   - Define _GNU_SOURCE for all selftests to fix a warning that was
     introduced by a change to kselftest_harness.h late in the 6.9
     cycle, and because forcing every test to #define _GNU_SOURCE is
     painful.

   - Provide a global pseudo-RNG instance for all tests, so that library
     code can generate random, but determinstic numbers.

   - Use the global pRNG to randomly force emulation of select writes
     from guest code on x86, e.g. to help validate KVM's emulation of
     locked accesses.

   - Allocate and initialize x86's GDT, IDT, TSS, segments, and default
     exception handlers at VM creation, instead of forcing tests to
     manually trigger the related setup.

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

    than dmesg (large number of driver changes from Asbjørn Sloth Tønnesen).

4f8b6f25eb - Add a dm-crypt optional "high_priority" flag that enables the crypt 
workqueues to use WQ_HIGHPRI.
 
 - Export dm-crypt workqueues via sysfs (by enabling WQ_SYSFS) to allow
   for improved visibility and controls over IO and crypt workqueues.
 
 - Fix dm-crypt to no longer constrain max_segment_size to PAGE_SIZE.
   This limit isn't needed given that the block core provides late bio
   splitting if bio exceeds underlying limits (e.g. max_segment_size).
 
 - Fix dm-crypt crypt_queue's use of WQ_UNBOUND to not use
   WQ_CPU_INTENSIVE because it is meaningless with WQ_UNBOUND.
 
 - Fix various issues with dm-delay target (ranging from a resource
   teardown fix, a fix for hung task when using kthread mode, and other
   improvements that followed from code inspection).

 "This was a quiet release cycle for the GPIO tree and so this

  We have one new driver, some minor improvements to the GPIO core code

  general nothing stands out or is controversial. All changes have spent
  time in next with no reported issues (or ones that were quickly
  fixed).

9d81e2d5a9 pwm: Changes for v6.10-rc1 
Apart for the normal updates for dt bindings, cleanups and support for
 new device variants to existing drivers this completes the conversion to
 pwmchip_alloc() which was started in the v6.9 development cycle.
 
 Using pwmchip_alloc() is a precondition to the character device support
 which allows easier and faster access to PWM devices. However there are

Pull pwm updates from Uwe Kleine-König:
 "Apart for the normal updates for dt bindings, cleanups and support for
  new device variants to existing drivers this completes the conversion
  to pwmchip_alloc() which was started in the v6.9 development cycle.

  Using pwmchip_alloc() is a precondition to the character device
  support which allows easier and faster access to PWM devices. However
  there are some issues I want to clean up before including it in
  mainline, so this isn't contained here despite it was in next for some
  time.

07bbfc6aba regulator: Updates for v6.10 
There's one API update here, a new API factoring out a common pattern
 for reference voltage supplies.  These are supplies uses as a reference
 by analogue circuits where the consumer requests and enables the supply,
 reads the voltage to calibrate the user and then never touches it again.
 This is factored out into a single operation which just returns the
 voltage and uses devm_ to manage the request and enable portion.
 
 Otherwise this has been a very quiet release, we've got some new device
 support, some small fixes, housekeeping and cleanup work but nothing
 substantial.
 
 There's also some non-regulator changes in here, a number of users for
 the new reference voltage API were merged along with it and some MFD
 changes were pulled in as dependencies for new driver work.
 
 Highlights:
 
  - Add a new API for single operation handling of reference voltages.
  - Support for Allwinner AXP717 and D1, and NXP PCA9561A.

Pull thermal control updates from Rafael Wysocki:
 "The most significant part of this is a rework of thermal governors,
  including a redesign of the thermal governor interface and changes to
  make some of them take trip point hysteresis into account properly, as
  well as some related cleanups of the thermal governors and thermal
  core.

  The above is based on preliminary changes refactoring thermal data
  structures and moving the definitions of some of them into the thermal
  core which also ensure that trip point crossing notifications will be
  sent to user space via netlink and recorded in the debug statistics in
  temperature order.

  In addition, netlink bind/unbind notifications are added to the
  thermal core and the Intel HFI driver is modified to use them to avoid
  sending netlink messages until there are subscribers.

  Apart from that, multiple thermal drivers are updated which includes
  new hardware support (MediaTek MT8188 and MT8186, Amlogic A1 thermal
  sensor, Loongson-2K2000, Lmh QCM2290), fixes, cleanups and
  documentation updates, and the recently added thermal debug code is
  fixed and cleaned up.

9776dd3609 X86 interrupt handling update: 
Support for posted interrupts on bare metal
 
     Posted interrupts is a virtualization feature which allows to inject
     interrupts directly into a guest without host interaction. The VT-d
     interrupt remapping hardware sets the bit which corresponds to the
     interrupt vector in a vector bitmap which is either used to inject the
     interrupt directly into the guest via a virtualized APIC or in case
     that the guest is scheduled out provides a host side notification
     interrupt which informs the host that an interrupt has been marked
     pending in the bitmap.
 
     This can be utilized on bare metal for scenarios where multiple
     devices, e.g. NVME storage, raise interrupts with a high frequency.  In
     the default mode these interrupts are handles independently and
     therefore require a full roundtrip of interrupt entry/exit.
 
     Utilizing posted interrupts this roundtrip overhead can be avoided by
     coalescing these interrupt entries to a single entry for the posted
     interrupt notification. The notification interrupt then demultiplexes
     the pending bits in a memory based bitmap and invokes the corresponding
     device specific handlers.
 
     Depending on the usage scenario and device utilization throughput
     improvements between 10% and 130% have been measured.
 
     As this is only relevant for high end servers with multiple device
     queues per CPU attached and counterproductive for situations where
     interrupts are arriving at distinct times, the functionality is opt-in
     via a kernel command line parameter.

- Core code:
 
    - Interrupt storm detection for the lockup watchdog:
 
      Lockups which are caused by interrupt storms are not easy to debug
      because there is no information about the events which make the lockup
      detector trigger.
 
      To make this more user friendly, provide an extenstion to interrupt
      statistics which allows to take snapshots and an interface to retrieve
      the delta to the snapshot. Use this new mechanism in the watchdog code
      to do a two stage lockup analysis by taking the snapshot and printing
      the deltas for the topmost active interrupts on the second trigger.
 
      Note: This contains both the interrupt and the watchdog changes as
      the latter depend on the former obviously.
 
   - Avoid summation loops in the /proc/interrupts output and use the global
     counter when possible
 
   - Skip suspended interrupts on CPU hotplug operations to ensure that they
     are not delivered before the system resumes the device drivers when
     coming out of suspend.
 
   - On CPU hot-unplug interrupts which are affine to the outgoing CPU are
     migrated to a different CPU in the affinity mask. This can fail when
     the CPUs have no vectors left. Instead of giving up try to migrate it
     to any online CPU and thereby breaking the affinity setting in order to
     prevent a stale device interrupt which targets an offline CPU

  - Driver code:
 
   - Support for the RISCV AIA MSI controller
 
   - Make the interrupt allocation for the Loongson PCH controller more
     flexible to prevent vector exhaustion

2d9db778dd Timers and timekeeping updates: 
- Core code:
 
    - Make timekeeping and VDSO time readouts resilent against math overflow:
 
      In guest context the kernel is prone to math overflow when the host
      defers the timer interrupt due to overload, malfunction or malice.
 
      This can be mitigated by checking the clocksource delta for the
      maximum deferrement which is readily available. If that value is
      exceeded then the code uses a slowpath function which can handle the
      multiplication overflow.
 
      This functionality is enabled unconditionally in the kernel, but made
      conditional in the VDSO code. The latter is conditional because it
      allows architectures to optimize the check so it is not causing
      performance regressions.
 
      On X86 this is achieved by reworking the existing check for negative
      TSC deltas as a negative delta obviously exceeds the maximum
      deferrement when it is evaluated as an unsigned value. That avoids two
      conditionals in the hotpath and allows to hide both the negative delta
      and the large delta handling in the same slow path.
 
    - Add an initial minimal ktime_t abstraction for Rust
 
    - The usual boring cleanups and enhancements
 
  - Drivers:

defa9cca02 dt-bindings: net: bluetooth: Add MediaTek MT7921S SDIO Bluetooth 
The MediaTek MT7921S is a WiFi/Bluetooth combo chip that works over
SDIO. WiFi and Bluetooth are separate SDIO functions within the chip.
While the Bluetooth SDIO function is fully discoverable, the chip has
a pin that can reset just the Bluetooth core, as opposed to the full
chip. This should be described in the device tree.

Add a device tree binding for the Bluetooth SDIO function of the MT7921S
specifically to document the reset line. This binding is based on the MMC
controller binding, which specifies one device node per SDIO function.

CYW43439 is a Wi-Fi + Bluetooth combo device from Infineon.
The Bluetooth part is capable of Bluetooth 5.2 BR/EDR/LE .
This chip is present e.g. on muRata 1YN module.

Extend the binding with its DT compatible using fallback
compatible string to "brcm,bcm4329-bt" which seems to be
the oldest compatible device. This should also prevent the
growth of compatible string tables in drivers. The existing
block of compatible strings is retained.

====================
pull-request: bpf-next 2024-05-13

We've added 119 non-merge commits during the last 14 day(s) which contain
a total of 134 files changed, 9462 insertions(+), 4742 deletions(-).

The main changes are:

1) Add BPF JIT support for 32-bit ARCv2 processors, from Shahab Vahedi.

2) Add BPF range computation improvements to the verifier in particular
   around XOR and OR operators, refactoring of checks for range computation
   and relaxing MUL range computation so that src_reg can also be an unknown
   scalar, from Cupertino Miranda.

3) Add support to attach 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,
   from Jiri Olsa.

4) Fix a potential overflow in libbpf's ring__consume_n() and improve libbpf
   as well as BPF selftest's struct_ops handling, from Andrii Nakryiko.

5) Improvements to BPF selftests in context of BPF gcc backend,
   from Jose E. Marchesi & David Faust.

6) Migrate remaining BPF selftest tests from test_sock_addr.c to prog_test-
   -style in order to retire the old test, run it in BPF CI and additionally
   expand test coverage, from Jordan Rife.

7) Big batch for BPF selftest refactoring in order to remove duplicate code
   around common network helpers, from Geliang Tang.

8) Another batch of improvements to BPF selftests to retire obsolete
   bpf_tcp_helpers.h as everything is available vmlinux.h,
   from Martin KaFai Lau.

9) Fix BPF map tear-down to not walk the map twice on free when both timer
   and wq is used, from Benjamin Tissoires.

10) Fix BPF verifier assumptions about socket->sk that it can be non-NULL,
    from Alexei Starovoitov.

11) Change BTF build scripts to using --btf_features for pahole v1.26+,
    from Alan Maguire.

12) Small improvements to BPF reusing struct_size() and krealloc_array(),
    from Andy Shevchenko.

13) Fix s390 JIT to emit a barrier for BPF_FETCH instructions,
    from Ilya Leoshkevich.

14) Extend TCP ->cong_control() callback in order to feed in ack and
    flag parameters and allow write-access to tp->snd_cwnd_stamp
    from BPF program, from Miao Xu.

15) Add support for internal-only per-CPU instructions to inline
    bpf_get_smp_processor_id() helper call for arm64 and riscv64 BPF JITs,
    from Puranjay Mohan.

16) Follow-up to remove the redundant ethtool.h from tooling infrastructure,
    from Tushar Vyavahare.

17) Extend libbpf to support "module:<function>" syntax for tracing
    programs, from Viktor Malik.

8f5b5f7811 Rust changes for v6.10 
The most notable change is the drop of the 'alloc' in-tree fork. This
 is nicely reflected in the diffstat as a ~10k lines drop. In turn, this
 makes the version upgrades way simpler and smaller in the future, e.g.
 the latest one in commit 56f64b3706 ("rust: upgrade to Rust 1.78.0").
 
 More importantly, this increases the chances that a newer compiler
 version just works, which in turn means supporting several compiler
 versions is easier now. Thus we will look into finally setting a minimum
 version in the near future.
 
 Toolchain and infrastructure:
 
  - Upgrade to Rust 1.78.0.
 
    This time around, due to how the kernel and Rust schedules have
    aligned, there are two upgrades in fact. These allow us to remove one
    more unstable feature ('offset_of') from the list, among other
    improvements.
 
  - Drop 'alloc' in-tree fork of the standard library crate, which means
    all the unstable features used by 'alloc' (~30 language ones, ~60
    library ones) are not a concern anymore.
 
  - Support DWARFv5 via the '-Zdwarf-version' flag.
 
  - Support zlib and zstd debuginfo compression via the
    '-Zdebuginfo-compression' flag.
 
 'kernel' crate:
 
  - Support allocation flags ('GFP_*'), particularly in 'Box' (via
    'BoxExt'), 'Vec' (via 'VecExt'), 'Arc' and 'UniqueArc', as well as in
    the 'init' module APIs.
 
  - Remove usage of the 'allocator_api' unstable feature.
 
  - Remove 'try_' prefix in allocation APIs' names.
 
  - Add 'VecExt' (an extension trait) to be able to drop the 'alloc'
    fork.
 
  - Add the '{make,to}_{upper,lower}case()' methods to 'CStr'/'CString'.
 
  - Add the 'as_ptr' method to 'ThisModule'.
 
  - Add the 'from_raw' method to 'ArcBorrow'.
 
  - Add the 'into_unique_or_drop' method to 'Arc'.
 
  - Display column number in the 'dbg!' macro output by applying the
    equivalent change done to the standard library one.
 
  - Migrate 'Work' to '#[pin_data]' thanks to the changes in the 'macros'
    crate, which allows to remove an unsafe call in its 'new' associated
    function.
 
  - Prevent namespacing issues when using the '[try_][pin_]init!' macros
    by changing the generated name of guard variables.
 
  - Make the 'get' method in 'Opaque' const.
 
  - Implement the 'Default' trait for 'LockClassKey'.
 
  - Remove unneeded 'kernel::prelude' imports from doctests.
 
  - Remove redundant imports.
 
 'macros' crate:
 
  - Add 'decl_generics' to 'parse_generics()' to support default values,
    and use that to allow them in '#[pin_data]'.
 
 Helpers:
 
  - Trivial English grammar fix.
 
 Documentation:
 
  - Add section on Rust Kselftests to the "Testing" document.
 
  - Expand the "Abstractions vs. bindings" section of the "General
    Information" document.

====================
Netfilter updates for net-next

The following patchset contains Netfilter updates for net-next:

Patch #1 skips transaction if object type provides no .update interface.

Patch #2 skips NETDEV_CHANGENAME which is unused.

Patch #3 enables conntrack to handle Multicast Router Advertisements and
	 Multicast Router Solicitations from the Multicast Router Discovery
	 protocol (RFC4286) as untracked opposed to invalid packets.
	 From Linus Luessing.

Patch #4 updates DCCP conntracker to mark invalid as invalid, instead of
	 dropping them, from Jason Xing.

Patch #5 uses NF_DROP instead of -NF_DROP since NF_DROP is 0,
	 also from Jason.

Patch #6 removes reference in netfilter's sysctl documentation on pickup
	 entries which were already removed by Florian Westphal.

Patch #7 removes check for IPS_OFFLOAD flag to disable early drop which
	 allows to evict entries from the conntrack table,
	 also from Florian.

Patches #8 to #16 updates nf_tables pipapo set backend to allocate
	 the datastructure copy on-demand from preparation phase,
	 to better deal with OOM situations where .commit step is too late
	 to fail. Series from Florian Westphal.

Patch #17 adds a selftest with packetdrill to cover conntrack TCP state
	 transitions, also from Florian.

Patch #18 use GFP_KERNEL to clone elements from control plane to avoid
	 quick atomic reserves exhaustion with large sets, reporter refers
	 to million entries magnitude.

b19239143e Hi, 
These are the changes for the TPM driver with a single major new
 feature: TPM bus encryption and integrity protection. The key pair
 on TPM side is generated from so called null random seed per power
 on of the machine [1]. This supports the TPM encryption of the hard
 drive by adding layer of protection against bus interposer attacks.
 
 Other than the pull request a few minor fixes and documentation for
 tpm_tis to clarify basics of TPM localities for future patch review

Merge tag 'tpmdd-next-6.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jarkko/linux-tpmdd

Pull TPM updates from Jarkko Sakkinen:
 "These are the changes for the TPM driver with a single major new
  feature: TPM bus encryption and integrity protection. The key pair on
  TPM side is generated from so called null random seed per power on of
  the machine [1]. This supports the TPM encryption of the hard drive by
  adding layer of protection against bus interposer attacks.

  Other than that, a few minor fixes and documentation for tpm_tis to
  clarify basics of TPM localities for future patch review discussions
  (will be extended and refined over times, just a seed)"
