The clock framework handles clock rates as "unsigned long", so u32 on
32-bit architectures and u64 on 64-bit architectures.

The current code casts the dividend to u64 on 32-bit to avoid a
potential overflow. For example DIV_ROUND_UP(3000000000, 1500000000)
= (3.0G + 1.5G - 1) / 1.5G = = OVERFLOW / 1.5G, which has been
introduced in commit 9556f9da ("clk: divider: handle integer overflow
when dividing large clock rates").

On 64 bit platforms this masks the divisor, so that only the lower
32 bit are used. Thus requesting a frequency >= 4.3GHz results
in incorrect values. For example requesting 4300000000 (4.3 GHz) will
effectively request ca. 5 MHz. Requesting clk_round_rate(clk, ULONG_MAX)
is a bit of a special case, since that still returns correct values as
long as the parent clock is below 8.5 GHz.

Fix this by switching to DIV_ROUND_UP_NO_OVERFLOW, which cannot
overflow. This avoids any requirements on the arguments (except
that divisor should not be 0 obviously).

Add hardware description for the USB-C port in the Radxa Rock 5 Model B.
This describes the OHCI, EHCI and XHCI USB parts, but not yet the
DisplayPort AltMode (bindings are not yet upstream).

For now the fusb302 node is marked with status "fail", since the board
is usually powered through the USB-C port. Handling of errors can result
in hard resets, which removed the bus power for some time resulting in
a board reset.

The main problem right now is that devices are supposed to interact with
the power-supply within 5 seconds after the plug event according to the
USB PD specification. This is more or less impossible to achieve when
the kernel is the first software communicating with the power-supply.

Currently the most likely workaround will be USB-PD handling added to
U-Boot. In that case U-Boot can update the status to "okay". That way
booting a kernel with the updated DT on an old U-Boot avoids a reset
loop.

Add CI support. This will do the following:

1. Run dt_binding_check to make sure no major flaws were introduced in
   the DT bindings
2. Run dtbs_check, for Rock 5A, Rock 5B and EVB1. If warnings are
   generated the CI will report that as warning
3. Build a Kernel .deb package
4. Generate a test job for LAVA and run it

 "There's one big bit of work this time around, the addition of support

  The MBQ register maps generally have variable register sizes, the
  variable regiseter size support allows them to be handled much more
  naturally within regmap with less open coding in drivers.

  The deferred read/write support avoids spurious errors when devices
  make use of a bus feature allowing them to indicate they're busy.

Pull networking updates from Paolo Abeni:
 "This is slightly smaller than usual, with the most interesting work
  being still around RTNL scope reduction.

  Core:

   - More core refactoring to reduce the RTNL lock contention, including
     preparatory work for the per-network namespace RTNL lock, replacing
     RTNL lock with a per device-one to protect NAPI-related net device
     data and moving synchronize_net() calls outside such lock.

   - Extend drop reasons usage, adding net scheduler, AF_UNIX, bridge
     and more specific TCP coverage.

   - Reduce network namespace tear-down time by removing per-subsystems
     synchronize_net() in tipc and sched.

   - Add flow label selector support for fib rules, allowing traffic
     redirection based on such header field.

  Netfilter:

   - Do not remove netdev basechain when last device is gone, allowing
     netdev basechains without devices.

   - Revisit the flowtable teardown strategy, dealing better with fin,
     reset and re-open events.

   - Scale-up IP-vs connection dumping by avoiding linear search on each
     restart.

  Protocols:

   - A significant XDP socket refactor, consolidating and optimizing
     several helpers into the core

   - Better scaling of ICMP rate-limiting, by removing false-sharing in
     inet peers handling.

   - Introduces netlink notifications for multicast IPv4 and IPv6
     address changes.

   - Add ipsec support for IP-TFS/AggFrag encapsulation, allowing
     aggregation and fragmentation of the inner IP.

   - Add sysctl to configure TIME-WAIT reuse delay for TCP sockets, to
     avoid local port exhaustion issues when the average connection
     lifetime is very short.

   - Support updating keys (re-keying) for connections using kernel TLS
     (for TLS 1.3 only).

   - Support ipv4-mapped ipv6 address clients in smc-r v2.

   - Add support for jumbo data packet transmission in RxRPC sockets,
     gluing multiple data packets in a single UDP packet.

   - Support RxRPC RACK-TLP to manage packet loss and retransmission in
     conjunction with the congestion control algorithm.

  Driver API:

   - Introduce a unified and structured interface for reporting PHY
     statistics, exposing consistent data across different H/W via
     ethtool.

   - Make timestamping selectable, allow the user to select the desired
     hwtstamp provider (PHY or MAC) administratively.

   - Add support for configuring a header-data-split threshold (HDS)
     value via ethtool, to deal with partial or buggy H/W
     implementation.

   - Consolidate DSA drivers Energy Efficiency Ethernet support.

   - Add EEE management to phylink, making use of the phylib
     implementation.

   - Add phylib support for in-band capabilities negotiation.

   - Simplify how phylib-enabled mac drivers expose the supported
     interfaces.

  Tests and tooling:

   - Make the YNL tool package-friendly to make it easier to deploy it
     separately from the kernel.

   - Increase TCP selftest coverage importing several packetdrill
     test-cases.

   - Regenerate the ethtool uapi header from the YNL spec, to ease
     maintenance and future development.

   - Add YNL support for decoding the link types used in net self-tests,
     allowing a single build to run both net and drivers/net.

When the 'cachestat()' system call was added in commit cf264e13
("cachestat: implement cachestat syscall"), it was meant to be a much
more convenient (and performant) version of mincore() that didn't need
mapping things into the user virtual address space in order to work.

But it ended up missing the "check for writability or ownership" fix for
mincore(), done in commit 134fca90 ("mm/mincore.c: make mincore()
more conservative").

This just adds equivalent logic to 'cachestat()', modified for the file
context (rather than vma).

Pull selinux updates from Paul Moore:

 - Extended permissions supported in conditional policy

   The SELinux extended permissions, aka "xperms", allow security admins
   to target individuals ioctls, and recently netlink messages, with
   their SELinux policy. Adding support for conditional policies allows
   admins to toggle the granular xperms using SELinux booleans, helping
   pave the way for greater use of xperms in general purpose SELinux
   policies. This change bumps the maximum SELinux policy version to 34.

 - Fix a SCTP/SELinux error return code inconsistency

   Depending on the loaded SELinux policy, specifically it's
   EXTSOCKCLASS support, the bind(2) LSM/SELinux hook could return
   different error codes due to the SELinux code checking the socket's
   SELinux object class (which can vary depending on EXTSOCKCLASS) and
   not the socket's sk_protocol field. We fix this by doing the obvious,
   and looking at the sock->sk_protocol field instead of the object
   class.

 - Makefile fixes to properly cleanup av_permissions.h

   Add av_permissions.h to "targets" so that it is properly cleaned up
   using the kbuild infrastructure.

 - A number of smaller improvements by Christian Göttsche

   types.

Pull lsm updates from Paul Moore:

 - Improved handling of LSM "secctx" strings through lsm_context struct

   The LSM secctx string interface is from an older time when only one
   LSM was supported, migrate over to the lsm_context struct to better
   support the different LSMs we now have and make it easier to support
   new LSMs in the future.

   These changes explain the Rust, VFS, and networking changes in the
   diffstat.

 - Only build lsm_audit.c if CONFIG_SECURITY and CONFIG_AUDIT are
   enabled

   Small tweak to be a bit smarter about when we build the LSM's common
   audit helpers.

 - Check for absurdly large policies from userspace in SafeSetID

   SafeSetID policies rules are fairly small, basically just "UID:UID",
   it easy to impose a limit of KMALLOC_MAX_SIZE on policy writes which
   helps quiet a number of syzbot related issues. While work is being
   done to address the syzbot issues through other mechanisms, this is a
   trivial and relatively safe fix that we can do now.

 "Toolchain and infrastructure:

   - Finish the move to custom FFI integer types started in the previous
     cycle and finally map 'long' to 'isize' and 'char' to 'u8'. Do a
     few cleanups on top thanks to that.

   - Start to use 'derive(CoercePointee)' on Rust >= 1.84.0.

     This is a major milestone on the path to build the kernel using
     only stable Rust features. In particular, previously we were using
     the unstable features 'coerce_unsized', 'dispatch_from_dyn' and
     'unsize', and now we will use the new 'derive_coerce_pointee' one,
     which is on track to stabilization. This new feature is a macro
     that essentially expands into code that internally uses the
     unstable features that we were using before, without having to
     expose those.

     With it, stable Rust users, including the kernel, will be able to
     build custom smart pointers that work with trait objects, e.g.:

         fn f(p: &Arc<dyn Display>) {
             pr_info!("{p}\n");
         }

         let a: Arc<dyn Display> = Arc::new(42i32, GFP_KERNEL)?;
         let b: Arc<dyn Display> = Arc::new("hello there", GFP_KERNEL)?;

         f(&a); // Prints "42".
         f(&b); // Prints "hello there".

     Together with the 'arbitrary_self_types' feature that we started
     using in the previous cycle, using our custom smart pointers like
     'Arc' will eventually only rely in stable Rust.

   - Introduce 'PROCMACROLDFLAGS' environment variable to allow to link
     Rust proc macros using different flags than those used for linking
     Rust host programs (e.g. when 'rustc' uses a different C library
     than the host programs' one), which Android needs.

   - Help kernel builds under macOS with Rust enabled by accomodating
     other naming conventions for dynamic libraries (i.e. '.so' vs.
     '.dylib') which are used for Rust procedural macros. The actual
     support for macOS (i.e. the rest of the pieces needed) is provided
     out-of-tree by others, following the policy used for other parts of
     the kernel by Kbuild.

   - Run Clippy for 'rusttest' code too and clean the bits it spotted.

   - Provide Clippy with the minimum supported Rust version to improve
     the suggestions it gives.

   - Document 'bindgen' 0.71.0 regression.

  'kernel' crate:

   - 'build_error!': move users of the hidden function to the documented
     macro, prevent such uses in the future by moving the function
     elsewhere and add the macro to the prelude.

   - 'types' module: add improved version of 'ForeignOwnable::borrow_mut'
     (which was removed in the past since it was problematic); change
     'ForeignOwnable' pointer type to '*mut'.

   - 'alloc' module: implement 'Display' for 'Box' and align the 'Debug'
     implementation to it; add example (doctest) for 'ArrayLayout::new()'

   - 'sync' module: document 'PhantomData' in 'Arc'; use
     'NonNull::new_unchecked' in 'ForeignOwnable for Arc' impl.

   - 'uaccess' module: accept 'Vec's with different allocators in
     'UserSliceReader::read_all'.

   - 'workqueue' module: enable run-testing a couple more doctests.

   - 'error' module: simplify 'from_errno()'.

   - 'block' module: fix formatting in code documentation (a lint to catch
     these is being implemented).

   - Avoid 'unwrap()'s in doctests, which also improves the examples by
     showing how kernel code is supposed to be written.

   - Avoid 'as' casts with 'cast{,_mut}' calls which are a bit safer.

  And a few other cleanups"

Pull kthread updates from Frederic Weisbecker:
 "Kthreads affinity follow either of 4 existing different patterns:

   1) Per-CPU kthreads must stay affine to a single CPU and never
      execute relevant code on any other CPU. This is currently handled
      by smpboot code which takes care of CPU-hotplug operations.
      Affinity here is a correctness constraint.

   2) Some kthreads _have_ to be affine to a specific set of CPUs and
      can't run anywhere else. The affinity is set through
      kthread_bind_mask() and the subsystem takes care by itself to
      handle CPU-hotplug operations. Affinity here is assumed to be a
      correctness constraint.

   3) Per-node kthreads _prefer_ to be affine to a specific NUMA node.
      This is not a correctness constraint but merely a preference in
      terms of memory locality. kswapd and kcompactd both fall into this
      category. The affinity is set manually like for any other task and
      CPU-hotplug is supposed to be handled by the relevant subsystem so
      that the task is properly reaffined whenever a given CPU from the
      node comes up. Also care should be taken so that the node affinity
      doesn't cross isolated (nohz_full) cpumask boundaries.

   4) Similar to the previous point except kthreads have a _preferred_
      affinity different than a node. Both RCU boost kthreads and RCU
      exp kworkers fall into this category as they refer to "RCU nodes"
      from a distinctly distributed tree.

  Currently the preferred affinity patterns (3 and 4) have at least 4
  identified users, with more or less success when it comes to handle
  CPU-hotplug operations and CPU isolation. Each of which do it in its
  own ad-hoc way.

  This is an infrastructure proposal to handle this with the following
  API changes:

   - kthread_create_on_node() automatically affines the created kthread
     to its target node unless it has been set as per-cpu or bound with
     kthread_bind[_mask]() before the first wake-up.

   - kthread_affine_preferred() is a new function that can be called
     right after kthread_create_on_node() to specify a preferred
     affinity different than the specified node.

  When the preferred affinity can't be applied because the possible
  targets are offline or isolated (nohz_full), the kthread is affine to
  the housekeeping CPUs (which means to all online CPUs most of the time
  or only the non-nohz_full CPUs when nohz_full= is set).

  kswapd, kcompactd, RCU boost kthreads and RCU exp kworkers have been
  converted, along with a few old drivers.

  Summary of the changes:

   - Consolidate a bunch of ad-hoc implementations of
     kthread_run_on_cpu()

   - Introduce task_cpu_fallback_mask() that defines the default last
     resort affinity of a task to become nohz_full aware

   - Add some correctness check to ensure kthread_bind() is always
     called before the first kthread wake up.

   - Default affine kthread to its preferred node.

   - Convert kswapd / kcompactd and remove their halfway working ad-hoc
     affinity implementation

   - Implement kthreads preferred affinity

   - Unify kthread worker and kthread API's style

   - Convert RCU kthreads to the new API and remove the ad-hoc affinity
     implementation"

Merge tag 'trace-sorttable-v6.14' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace

Pull scipts/sorttable updates from Steven Rostedt:
 "The sorttable.c was a copy from recordmcount.c which is very hard to
  maintain. That's because it uses macro helpers and places the code in
  a header file sorttable.h to handle both the 64 bit and 32 bit version
  of the Elf structures. It also uses _r()/r()/r2() wrappers around
  accessing the data which will read the 64 bit or 32 bit version of the
  data as well as handle endianess. If the wrong wrapper is used, an
  invalid value will result, and this has been a cause for bugs in the
  past. In fact the new ORC code doesn't even use it. That's fine
  because ORC is only for 64 bit x86 which is the default parsing.

  Instead of having a bunch of macros defined and then include the code
  twice from a header, the Elf structures are each wrapped in a union.
  The union holds the 64 bit and 32 bit version of the needed structure.
  Then a structure of function pointers is used, along with helper
  macros to access the ELF types appropriately for their byte size and
  endianess. How to reference the data fields is moved from the code
  that implements the sorting to the helper functions where all accesses
  to a field will use he same helper function. As long as the helper
  functions access the fields correctly, the code will also access the
  fields. This is an improvement over having to code implementing the
  sorting having to make sure it always uses the right accessor function
  when reading an ELF field.

  This is a clean up only, the functionality of the scripts/sorttable.c
  does not change"

Pull ftrace updates from Steven Rostedt:

 - Have fprobes built on top of function graph infrastructure

   The fprobe logic is an optimized kprobe that uses ftrace to attach to
   functions when a probe is needed at the start or end of the function.
   The fprobe and kretprobe logic implements a similar method as the
   function graph tracer to trace the end of the function. That is to
   hijack the return address and jump to a trampoline to do the trace
   when the function exits. To do this, a shadow stack needs to be
   created to store the original return address. Fprobes and function
   graph do this slightly differently. Fprobes (and kretprobes) has
   slots per callsite that are reserved to save the return address. This
   is fine when just a few points are traced. But users of fprobes, such
   as BPF programs, are starting to add many more locations, and this
   method does not scale.

   The function graph tracer was created to trace all functions in the
   kernel. In order to do this, when function graph tracing is started,
   every task gets its own shadow stack to hold the return address that
   is going to be traced. The function graph tracer has been updated to
   allow multiple users to use its infrastructure. Now have fprobes be
   one of those users. This will also allow for the fprobe and kretprobe
   methods to trace the return address to become obsolete. With new
   technologies like CFI that need to know about these methods of
   hijacking the return address, going toward a solution that has only
   one method of doing this will make the kernel less complex.

 - Cleanup with guard() and free() helpers

   There were several places in the code that had a lot of "goto out" in
   the error paths to either unlock a lock or free some memory that was
   allocated. But this is error prone. Convert the code over to use the
   guard() and free() helpers that let the compiler unlock locks or free
   memory when the function exits.

 - Remove disabling of interrupts in the function graph tracer

   When function graph tracer was first introduced, it could race with
   interrupts and NMIs. To prevent that race, it would disable
   interrupts and not trace NMIs. But the code has changed to allow NMIs
   and also interrupts. This change was done a long time ago, but the
   disabling of interrupts was never removed. Remove the disabling of
   interrupts in the function graph tracer is it is not needed. This
   greatly improves its performance.

 - Allow the :mod: command to enable tracing module functions on the
   kernel command line.

   The function tracer already has a way to enable functions to be
   traced in modules by writing ":mod:<module>" into set_ftrace_filter.
   That will enable either all the functions for the module if it is
   loaded, or if it is not, it will cache that command, and when the
   module is loaded that matches <module>, its functions will be
   enabled. This also allows init functions to be traced. But currently
   events do not have that feature.

   Because enabling function tracing can be done very early at boot up
   (before scheduling is enabled), the commands that can be done when
   function tracing is started is limited. Having the ":mod:" command to
   trace module functions as they are loaded is very useful. Update the
   kernel command line function filtering to allow it.

Pull trace ring-buffer updates from Steven Rostedt:

 - Clean up the __rb_map_vma() logic

   The logic of __rb_map_vma() has a error check with WARN_ON() that
   makes sure that the index does not go past the end of the array of
   buffers. The test in the loop pretty much guarantees that it will
   never happen, but since the relation of the variables used is a
   little complex, the WARN_ON() check was added. It was noticed that
   the array was dereferenced before this check and if the logic does
   break and for some reason the logic goes past the array, there will
   be an out of bounds access here. Move the access to after the
   WARN_ON().

 - Consolidate how the ring buffer is determined to be empty

   Currently there's two ways that are used to determine if the ring
   buffer is empty. One relies on the status of the commit and reader
   pages and what was read, and the other is on what was written vs what
   was read. By using the number of entries (written) method, it can be
   used for reading events that are out of the kernel's control (what
   pKVM will use). Move to this method to make it easier to implement a
   pKVM ring buffer that the kernel can read.

Pull interrupt subsystem updates from Thomas Gleixner:

 - Consolidate the machine_kexec_mask_interrupts() by providing a
   generic implementation and replacing the copy & pasta orgy in the
   relevant architectures.

 - Prevent unconditional operations on interrupt chips during kexec
   shutdown, which can trigger warnings in certain cases when the
   underlying interrupt has been shut down before.

 - Make the enforcement of interrupt handling in interrupt context
   unconditionally available, so that it actually works for non x86
   related interrupt chips. The earlier enablement for ARM GIC chips set
   the required chip flag, but did not notice that the check was hidden
   behind a config switch which is not selected by ARM[64].

 - Decrapify the handling of deferred interrupt affinity setting.

   Some interrupt chips require that affinity changes are made from the
   context of handling an interrupt to avoid certain race conditions.
   For x86 this was the default, but with interrupt remapping this
   requirement was lifted and a flag was introduced which tells the core
   code that affinity changes can be done in any context. Unrestricted
   affinity changes are the default for the majority of interrupt chips.

   RISCV has the requirement to add the deferred mode to one of it's
   interrupt controllers, but with the original implementation this
   would require to add the any context flag to all other RISC-V
   interrupt chips. That's backwards, so reverse the logic and require
   that chips, which need the deferred mode have to be marked
   accordingly. That avoids chasing the 'sane' chips and marking them.

 - Add multi-node support to the Loongarch AVEC interrupt controller
   driver.
