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).

Linus Torvalds
b850dc206a firewire updates for v6.10 
During the development period of v6.8 kernel, it became evident that there
 was a lack of helper utilities to trace the initial state of bus, while
 investigating certain PHYs compliant with different versions of IEEE 1394
 specification.
 
 This series of changes includes the addition of tracepoints events,
 provided by 'firewire' subsystem. These events enable tracing of how
 firewire core functions during bus reset and asynchronous communication
 over IEEE 1394 bus.
 
 When implementing the tracepoints events, it was found that the existing
 serialization and deserialization helpers for several types of
 asynchronous packets are scattered across both firewire-core and
 firewire-ohci kernel modules. A set of inline functions is newly added

Merge tag 'firewire-updates-6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/ieee1394/linux1394

Pull firewire updates from Takashi Sakamoto:
 "During the development period of v6.8 kernel, it became evident that
  there was a lack of helper utilities to trace the initial state of
  bus, while investigating certain PHYs compliant with different
  versions of IEEE 1394 specification.

  This series of changes includes the addition of tracepoints events,
  provided by 'firewire' subsystem. These events enable tracing of how
  firewire core functions during bus reset and asynchronous
  communication over IEEE 1394 bus.

  When implementing the tracepoints events, it was found that the
  existing serialization and deserialization helpers for several types
  of asynchronous packets are scattered across both firewire-core and
  firewire-ohci kernel modules. A set of inline functions is newly added
  to address it, along with some KUnit tests, serving as the foundation
  for the tracepoints events. This renders the dispersed code obsolete.

  The remaining changes constitute the final steps in phasing out the
  usage of deprecated PCI MSI APIs, in continuation from the previous
  version"

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).

6fffab6676 dlm for 6.10 
- Fix a long standing race between the unlock callback for the last lkb

 This could lead different nodes to inconsistent info about the rsb master
 node.
 
 - Remove unnecessary refcounting on callback structs, returning to the way

 - Do message processing in softirq context.  This allows dlm messages to
 be cleared more quickly and efficiently, reducing long lists of incomplete
 requests.  A future change to run callbacks directly from this context
 will make this more effective.
 
 - The softirq message processing involved a number of patches changing
 mutexes to spinlocks and rwlocks, and a fair amount of code re-org in
 preparation.
 
 - Use an rhashtable for rsb structs, rather than our old internal hash
 table implementation.  This also required some re-org of lists and locks
 preparation for the change.
 
 - Drop the dlm_scand kthread, and use timers to clear unused rsb structs.
 Scanning all rsb's periodically was a lot of wasted work.
 
 - Fix recent regression in logic for copying LVB data in user space lock

Pull btrfs updates from David Sterba:
 "This update brings a few minor performance improvements, otherwise
  there's a lot of refactoring, cleanups and other sort of not user
  visible changes.

  Performance improvements:

   - inline b-tree locking functions, improvement in metadata-heavy
     changes

   - relax locking on a range that's being reflinked, allows read
     operations to run in parallel

   - speed up NOCOW write checks (throughput +9% on a sample test)

   - extent locking ranges have been reduced in several places, namely
     around delayed ref processing

  Core:

   - more page to folio conversions:
      - relocation
      - send
      - compression
      - inline extent handling
      - super block write and wait

   - extent_map structure optimizations:
      - reduced structure size
      - code simplifications
      - add shrinker for allocated objects, the numbers can go high and
        could exhaust memory on smaller systems (reported) as they may
        not get an opportunity to be freed fast enough

   - extent locking optimizations:
      - reduce locking ranges where it does not seem to be necessary and
        are safe due to other means of synchronization
      - potential improvements due to lower contention,
        allocation/freeing and state management operations of extent
        state tracking structures

   - delayed ref cleanups and simplifications

   - updated trace points

   - improved error handling, warnings and assertions

   - cleanups and refactoring, unification of error handling paths"

Pull erofs updates from Gao Xiang:
 "The LZ4 global buffer count is now configurable instead of the
  previous per-CPU buffers, which is useful for bare metals with
  hundreds of CPUs. A reserved buffer pool for LZ4 decompression can
  also be enabled to minimize the tail allocation latencies under the
  low memory scenarios with heavy memory pressure.

  In addition, Zstandard algorithm is now supported as an alternative
  since it has been requested by users for a while.

  There are some random cleanups as usual.

  Summary:

   - Make LZ4 global buffers configurable instead of per-CPU buffers

   - Add a reserved buffer pool for LZ4 decompression for lower latencies

   - Support Zstandard compression algorithm as an alternative

   - Derive fsid from on-disk UUID for .statfs() if possible

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
 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.

 Jerome Brunet and Varshini Rajendran for their contributions. Further

e2b4a5bf32 spi: Updates for v6.10 
The diffstat for this release is dominated by the new Airoha driver,
 mainly as a result of this being a generally quite quiet release.  There
 were a couple of cleanups in the core but nothing substantial, the
 updates here are almost all driver specific ones.
 
  - Support for multi-word mode in the OMAP2 McSPI driver.
  - Overhaul of the PXA2xx driver, mostly API updates.
  - A number of DT binding conversions.
  - Support for Airoha NAND controllers, Cirrus Logic CS35L56, Mobileye

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.

0dc83ad8bf clk: samsung: Don't register clkdev lookup for the fixed rate clocks 
Commit 4d11c62ca8d7 ("clkdev: report over-sized strings when creating
clkdev entries") revealed that clock lookup is registered for all fixed
clocks. The mentioned commit added a check if the registered name is not
too long. This fails for some clocks registered for Exynos542x SoCs family.
This lookup is a left-over from early common clock framework days, not
really needed nowadays, so remove it to avoid further issues.

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.

21c38a3bd4 cgroup/rstat: add cgroup_rstat_cpu_lock helpers and tracepoints 
This closely resembles helpers added for the global cgroup_rstat_lock in
commit fc29e04ae1 ("cgroup/rstat: add cgroup_rstat_lock helpers and
tracepoints"). This is for the per CPU lock cgroup_rstat_cpu_lock.

Based on production workloads, we observe the fast-path "update" function
cgroup_rstat_updated() is invoked around 3 million times per sec, while the
"flush" function cgroup_rstat_flush_locked(), walking each possible CPU,
can see periodic spikes of 700 invocations/sec.

For this reason, the tracepoints are split into normal and fastpath
versions for this per-CPU lock. Making it feasible for production to
continuously monitor the non-fastpath tracepoint to detect lock contention
issues. The reason for monitoring is that lock disables IRQs which can
disturb e.g. softirq processing on the local CPUs involved. When the
global cgroup_rstat_lock stops disabling IRQs (e.g converted to a mutex),
this per CPU lock becomes the next bottleneck that can introduce latency
variations.

A practical bpftrace script for monitoring contention latency:

 bpftrace -e '
   tracepoint:cgroup:cgroup_rstat_cpu_lock_contended {
     @start[tid]=nsecs; @cnt[probe]=count()}
   tracepoint:cgroup:cgroup_rstat_cpu_locked {
     if (args->contended) {
       @wait_ns=hist(nsecs-@start[tid]); delete(@start[tid]);}
     @cnt[probe]=count()}
   interval:s:1 {time("%H:%M:%S "); print(@wait_ns); print(@cnt); clear(@cnt);}'

Merge tag 'sh-for-v6.10-tag1' of git://git.kernel.org/pub/scm/linux/kernel/git/glaubitz/sh-linux

Pull sh updates from John Paul Adrian Glaubitz:
 "The majority of improvements are coming from Geert Uytterhoeven who
  took the time to fix a total of 30 cases of "-Wmissing-prototypes"
  compiler warnings, either by adding a missing header include, defining
  the missing forward declarations or making the functions in question
  static.

  In the case of several DMA functions, the fix was to actually just
  remove them as they were added but never used. Another one of these
  warnings was eliminated by removing the left-over sh5 cache handling
  support, a change that was suggested by Yoshinori Sato and, finally,
  the last of these warnings was fixed by guarding the function
  setup_profiling_timer() with CONFIG_PROFILING.

  While at it, Geert also removed two unneeded casts to kprobe_opcode_t
  in the kprobes code.

  Another change was contributed by Guenter Roeck to fix errors that
  were reported during checksum unit tests. The fix actually reverts the
  older change cadc4e1a2b ("sh: Handle calling csum_partial with
  misaligned data") which turned to be incorrect. It remains to be
  investigated whether there is a better way to handle misaligned data
  in csum_partial().

  A small fix contributed by Krzysztof Kozlowski drops the incorrect SPI
  controller spi-max-frequency property in the device tree source file
  for the J2 device platform while Uwe Kleine-König converted the
  push-switch driver to have its callback function return void, a change
  that is currently being applied to all drivers throughout the kernel
  in order to avoid resource leaks.

  Last but not least, Artur Rojek has fixed the IOPORT base address for
  the Sega Dreamcast platform which allows the Linux kernel to be
  successfully booted on this once popular video game console for the
  first time since a long time ago"

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.

6bfd2d442a Updates for the interrupt subsystem: 
- 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
 
   - The usual small cleanups
 
  - Driver code:
 
   - Support for the RISCV AIA MSI controller
 
   - Make the interrupt allocation for the Loongson PCH controller more
     flexible to prevent vector exhaustion
 
   - The usual set of cleanups and fixes all over the place

a9d9ce3fbc A single update for the TSC synchronixation sanity checks: 
The sad state of TSC being notoriously non-sychronized for several
   decades caused the kernel to grow quite rigorous sanity checks to detect
   whether the TSC is valid to be used for timekeeping.
 
   The TSC ADJUST MSR provides the offset between the initial TSC value
   after hardware reset and later modifications. This allows to detect cases
   where firmware tampers with the TSC and also allows to correct the
   firmware induced damage by resetting the offset in a controlled way.
 
   The universal correct rule is that the TSC ADJUST value has to be
   consistent within all CPUs of a socket.
 
   The kernel further assumes that the TSC offset should be consistent
   between sockets. That's not really correct as systems with a huge number
   of sockets are not architecurally guaranteed to reset the per socket TSC
   base synchronously.
 
   In case that the per socket offset is not consistent the kernel resets it
   to the offset of the boot CPU and then does a synchronization check which
   corrects for the inter socket delays.
 
   That works most of the time, but it is suboptimal as the firmware has
   eventually better information about the per socket offset and on sane
   systems that offset should just work in the validation checks.

      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

      This functionality is enabled unconditionally in the kernel, but made

      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.

d4e9a96873 eventfs: Fix a possible null pointer dereference in eventfs_find_events() 
In function eventfs_find_events,there is a potential null pointer
that may be caused by calling update_events_attr which will perform
some operations on the members of the ei struct when ei is NULL.

Hence,When ei->is_freed is set,return NULL directly.
