ea0b0bcef4 module: Annotate struct module_notes_attrs with __counted_by 
Prepare for the coming implementation by GCC and Clang of the __counted_by
attribute. Flexible array members annotated with __counted_by can have
their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS
(for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family
functions).

As found with Coccinelle[1], add __counted_by for struct module_notes_attrs.

3737df782c module/decompress: use vmalloc() for gzip decompression workspace 
Use a similar approach as commit a419beac4a ("module/decompress: use
vmalloc() for zstd decompression workspace") and replace kmalloc() with
vmalloc() also for the gzip module decompression workspace.

In this case the workspace is represented by struct inflate_workspace
that can be fairly large for kmalloc() and it can potentially lead to
allocation errors on certain systems:

$ pahole inflate_workspace
struct inflate_workspace {
	struct inflate_state       inflate_state;        /*     0  9544 */
	/* --- cacheline 149 boundary (9536 bytes) was 8 bytes ago --- */
	unsigned char              working_window[32768]; /*  9544 32768 */

	/* size: 42312, cachelines: 662, members: 2 */
	/* last cacheline: 8 bytes */
};

Considering that there is no need to use continuous physical memory,
simply switch to vmalloc() to provide a more reliable in-kernel module
decompression.

2c7ccb3c36 module: Clarify documentation of module_param_call() 
Commit 9bbb9e5a33 ("param: use ops in struct kernel_param, rather than
get and set fns directly") added the comment that module_param_call()
was deprecated, during a large scale refactoring to bring sanity to type
casting back then. In 2017 following more cleanups, it became useful
again as it wraps a common pattern of creating an ops struct for a
given get/set pair:

  b2f270e874 ("module: Prepare to convert all module_param_call() prototypes")
  ece1996a21 ("module: Do not paper over type mismatches in module_param_call()")

        static const struct kernel_param_ops __param_ops_##name = \
                { .flags = 0, .set = _set, .get = _get }; \
        __module_param_call(MODULE_PARAM_PREFIX, \
                            name, &__param_ops_##name, arg, perm, -1, 0)

        __module_param_call(MODULE_PARAM_PREFIX, name, ops, arg, perm, -1, 0)

Many users of module_param_cb() appear to be almost universally
open-coding the same thing that module_param_call() does now. Don't
discourage[1] people from using module_param_call(): clarify the comment
to show that module_param_cb() is useful if you repeatedly use the same
pair of get/set functions.

fe4ae2fab0 Herein lies a smallish collection of clk driver updates and some core 
clk framework changes for the merge window. The core framework changes
 are only improving the debugfs interface to allow phase adjustments and
 report which consumers of a clk there are. These are most likely only of
 interest to kernel developers.
 
 On the clk driver side, it's a ghastly amount of updates with only a
 handful of new clk drivers. We have a couple new clk drivers for
 Qualcomm, per usual, and a driver for Renesas, Amlogic, and TI
 respectively. The updates are spread throughout the clk drivers. Some
 highlights are fixing kunit tests for different configurations like
 lockdep and big-endian, avoiding integer overflow in rate settable clks,
 moving clk_hw_onecell_data to the end of allocations so that drivers
 don't corrupt their private data, and migrating clk drivers to the
 regmap maple tree. Otherwise it's the usual fixes to clk drivers that
 only come along with testing the drivers on real hardware.
 
 New Drivers:
  - Add clock driver for TWL6032
  - Initial support for the Qualcomm SM4450 Global Clock Controller and
    SM4450 RPMh clock controllers
  - Add Camera Clock Controller on Qualcomm SM8550
  - Add support for the Renesas RZ/G3S (R9A08G045) SoC
  - Add Amlogic s4 main clock controller support
 
 Updates:
  - Make clk kunit tests work with lockdep
  - Fix clk gate kunit test for big-endian
  - Convert more than a handful of clk drivers to use regmap maple tree
  - Consider the CLK_FRAC_DIVIDER_ZERO_BASED in fractional divider clk
    implementation
  - Add consumer info to clk debugfs
  - Fix various clk drivers that have clk_hw_onecell_data not at the end
    of an allocation
  - Drop CLK_SET_RATE_PARENT for clocks with fixed-rate GPLLs across a
    variety of Qualcomm IPQ platforms
  - Add missing parent of APCS PLL on Qualcomm IPQ6018
  - Add I2C QUP6 clk on Qualcomm IPQ6018 but mark it critical to avoid
    problems with RPM
  - Implement safe source switching for a53pll and use on Qualcomm
    IPQ5332
  - Add support for Stromer Plus PLLs to Qualcomm clk driver
  - Switch Qualcomm SM8550 Video and GPU clock controllers to use OLE PLL
    configure method
  - Non critical fixes to halt bit checks in Qualcomm clk drivers
  - Add SMMU GDSC for Qualcomm MSM8998
  - Fix possible integer overflow in Qualcomm RCG frequency calculation
    code
  - Remove RPM managed clks from Qualcomm MSM8996 GCC driver
  - Add HFPLL configuration for the three HFPLLs in Qualcomm MSM8976
  - Switch Qualcomm MSM8996 CBF clock driver's remove function to return
    void
  - Fix missing dependency for s4 clock controllers
  - Select MXC_CLK when building in the CLK_IMX8QXP
  - Fixes for error handling paths in i.MX8 ACM driver
  - Move the clocks check in i.MX8 ACM driver in order to log any error
  - Drop the unused return value of clk_imx_acm_detach_pm_domains
  - Drop non-existant IMX8MP_CLK_AUDIOMIX_PDM_ROOT clock
  - Fix error handling in i.MX8MQ clock driver
  - Allow a different LCDIF1 clock parent if DT describes it for i.MX6SX
  - Keep the SCU resource table sorted in the i.MX8DXL rsrc driver
  - Move the elcdif PLL clock registration above lcd_clk, as it is its
    parent
  - Correct some ENET specific clocks for i.MX8DXL platform
  - Drop the VPU_UART and VPUCORE from i.MX8QM as latest HW revision
    doesn't have them
  - Remove "de-featured" MLB support from i.MX8QM/QXP/DXL platforms
  - Skip registering clocks owned by Cortex-A partition SCU-based
    platforms
  - Add CAN_1/2 to i.MX8QM and M4_0, PI_0_PWM_0 and PI_0_I2C_0 to
    i.MX8QXP resources

The main change here is a fix for an issue where we were letting the
 selector for windowed register ranges get out of sync with the hardware
 during a cache sync plus associated KUnit tests.  This was reported just
 at the end of the release cycle and only in -next for a day prior to the
 merge window so it seemed better to hold off for now, the bug had been
 present for more than a decade so wasn't causing too many practical
 problems hopefully.  There's also a fix for error handling in the

Merge tag 'gpio-updates-for-v6.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux

Pull gpio updates from Bartosz Golaszewski:
 "We don't have any new drivers. The loongson driver is getting extended
  with support for new models. There's a big refactor of gpio-pca953x
  and many small improvements to others.

  The GPIO code in the kernel has acquired a lot of cruft over the years
  as well as many abusers of the API across the kernel tree. This
  release cycle we have started a major cleanup and improvement effort
  that will most likely span several releases. We have started by
  converting external users of struct gpio_chip to accessing the wrapper
  around it - struct gpio_device. This is because the latter is
  reference counted while the former is removed when the provider is
  unbound. We also removed several instances of drivers accessing
  private GPIOLIB structures and including the private header from
  drivers/gpio/.

  To that end you'll see several commits aimed at different subsystems
  (acked by relevant maintainers) as well as two merges from the
  x86/platform tree.

  We'll then rework the locking in GPIOLIB which currently uses a big
  spinlock for many different things and could use becoming more
  fine-grained, especially as it doesn't even get the locking right.
  We'll also use SRCU for protecting the gpio_chip pointer against
  in-kernel hot-unplug crashes similar to what we saw triggered from
  user-space and fixed with semaphores in gpiolib-cdev. The core GPIOLIB
  is still vulnerable to these use-cases. I'm just mentioning the plans
  here, this is not part of this PR.

  You'll see some new instances of using __free(). We've added a
  gpio_device_put cleanup helper similar to the put_device one
  introduced by Peter Zijlstra and used it according to the preferred
  pattern except where it didn't make sense.

  GPIOLIB core:
   - provide interfaces allowing users to retrieve, manage and query the
     reference counted GPIO device instead of accessing the private
     gpio_chip structure
   - replace gpiochip_find() with gpio_device_find()

  to it in the previous cycle, to make it easier to grasp, get rid of
  redundant pieces of internal data structures and eliminate its
  reliance on a specific ordering of trip point objects in the thermal

  rework, modify the thermal governor interface so as to use trip
  pointers for representing trip points in it, switch over multiple
  thermal drivers to using void platform driver remove callbacks, add
  support for 2 hardware features to the Intel int340x thermal driver,
  add support for new hardware on ARM platforms, update documentation,
  fix problems, clean up code and update the MAINTAINERS record for
  thermal control.

Linus Torvalds
89ed67ef12 Networking changes for 6.7. 
Core & protocols
 ----------------
 
  - Support usec resolution of TCP timestamps, enabled selectively by
    a route attribute.
 
  - Defer regular TCP ACK while processing socket backlog, try to send
    a cumulative ACK at the end. Increase single TCP flow performance
    on a 200Gbit NIC by 20% (100Gbit -> 120Gbit).
 
  - The Fair Queuing (FQ) packet scheduler:
    - add built-in 3 band prio / WRR scheduling
    - support bypass if the qdisc is mostly idle (5% speed up for TCP RR)
    - improve inactive flow reporting
    - optimize the layout of structures for better cache locality
 
  - Support TCP Authentication Option (RFC 5925, TCP-AO), a more modern
    replacement for the old MD5 option.
 
  - Add more retransmission timeout (RTO) related statistics to TCP_INFO.
 
  - Support sending fragmented skbs over vsock sockets.
 
  - Make sure we send SIGPIPE for vsock sockets if socket was shutdown().
 
  - Add sysctl for ignoring lower limit on lifetime in Router
    Advertisement PIO, based on an in-progress IETF draft.
 
  - Add sysctl to control activation of TCP ping-pong mode.
 
  - Add sysctl to make connection timeout in MPTCP configurable.
 
  - Support rcvlowat and notsent_lowat on MPTCP sockets, to help apps
    limit the number of wakeups.
 
  - Support netlink GET for MDB (multicast forwarding), allowing user
    space to request a single MDB entry instead of dumping the entire
    table.
 
  - Support selective FDB flushing in the VXLAN tunnel driver.
 
  - Allow limiting learned FDB entries in bridges, prevent OOM attacks.
 
  - Allow controlling via configfs netconsole targets which were created
    via the kernel cmdline at boot, rather than via configfs at runtime.
 
  - Support multiple PTP timestamp event queue readers with different
    filters.
 
  - MCTP over I3C.
 
 BPF
 ---
 
  - Add new veth-like netdevice where BPF program defines the logic
    of the xmit routine. It can operate in L3 and L2 mode.
 
  - Support exceptions - allow asserting conditions which should
    never be true but are hard for the verifier to infer.
    With some extra flexibility around handling of the exit / failure.
    https://lwn.net/Articles/938435/
 
  - Add support for local per-cpu kptr, allow allocating and storing
    per-cpu objects in maps. Access to those objects operates on
    the value for the current CPU. This allows to deprecate local
    one-off implementations of per-CPU storage like
    BPF_MAP_TYPE_PERCPU_CGROUP_STORAGE maps.
 
  - Extend cgroup BPF sockaddr hooks for UNIX sockets. The use case is
    for systemd to re-implement the LogNamespace feature which allows
    running multiple instances of systemd-journald to process the logs
    of different services.
 
  - Enable open-coded task_vma iteration, after maple tree conversion
    made it hard to directly walk VMAs in tracing programs.
 
  - Add open-coded task, css_task and css iterator support.
    One of the use cases is customizable OOM victim selection via BPF.
 
  - Allow source address selection with bpf_*_fib_lookup().
 
  - Add ability to pin BPF timer to the current CPU.
 
  - Prevent creation of infinite loops by combining tail calls and
    fentry/fexit programs.
 
  - Add missed stats for kprobes to retrieve the number of missed kprobe
    executions and subsequent executions of BPF programs.
 
  - Inherit system settings for CPU security mitigations.
 
  - Add BPF v4 CPU instruction support for arm32 and s390x.
 
 Changes to common code
 ----------------------
 
  - overflow: add DEFINE_FLEX() for on-stack definition of structs
    with flexible array members.
 
  - Process doc update with more guidance for reviewers.
 
 Driver API
 ----------
 
  - Simplify locking in WiFi (cfg80211 and mac80211 layers), use wiphy
    mutex in most places and remove a lot of smaller locks.
 
  - Create a common DPLL configuration API. Allow configuring
    and querying state of PLL circuits used for clock syntonization,
    in network time distribution.
 
  - Unify fragmented and full page allocation APIs in page pool code.
    Let drivers be ignorant of PAGE_SIZE.
 
  - Rework PHY state machine to avoid races with calls to phy_stop().
 
  - Notify DSA drivers of MAC address changes on user ports, improve
    correctness of offloads which depend on matching port MAC addresses.
 
  - Allow antenna control on injected WiFi frames.
 
  - Reduce the number of variants of napi_schedule().
 
  - Simplify error handling when composing devlink health messages.
 
 Misc
 ----
 
  - A lot of KCSAN data race "fixes", from Eric.
 
  - A lot of __counted_by() annotations, from Kees.
 
  - A lot of strncpy -> strscpy and printf format fixes.
 
  - Replace master/slave terminology with conduit/user in DSA drivers.
 
  - Handful of KUnit tests for netdev and WiFi core.

455cdcb45f Rust changes for v6.7 
A small one compared to the previous one in terms of features. In terms
 of lines, as usual, the 'alloc' version upgrade accounts for most of them.
 
 Toolchain and infrastructure:
 
  - Upgrade to Rust 1.73.0.
 
    This time around, due to how the kernel and Rust schedules have
    aligned, there are two upgrades in fact. They contain the fixes for
    a few issues we reported to the Rust project.
 
    In addition, a few cleanups indicated by the upgraded compiler
    or possible thanks to it. For instance, the compiler now detects
    redundant explicit links.
 
  - A couple changes to the Rust 'Makefile' so that it can be used with
    toybox tools, allowing Rust to be used in the Android kernel build.
 
 x86:
 
  - Enable IBT if enabled in C.
 
 Documentation:
 
  - Add "The Rust experiment" section to the Rust index page.
 
 MAINTAINERS
 
  - Add Maintainer Entry Profile field ('P:').
 
  - Update our 'W:' field to point to the webpage we have been building
    this year.

Merge tag 'execve-v6.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux

Pull execve updates from Kees Cook:

 - Support non-BSS ELF segments with zero filesz

   Eric Biederman and I refactored ELF segment loading to handle the
   case where a segment has a smaller filesz than memsz. Traditionally
   linkers only did this for .bss and it was always the last segment. As
   a result, the kernel only handled this case when it was the last
   segment. We've had two recent cases where linkers were trying to use
   these kinds of segments for other reasons, and the were in the middle
   of the segment list. There was no good reason for the kernel not to
   support this, and the refactor actually ends up making things more
   readable too.

 - Enable namespaced binfmt_misc

   Christian Brauner has made it possible to use binfmt_misc with mount
   namespaces. This means some traditionally root-only interfaces (for
   adding/removing formats) are now more exposed (but believed to be
   safe).

 - Remove struct tag 'dynamic' from ELF UAPI

   Alejandro Colomar noticed that the ELF UAPI has been polluting the
   struct namespace with an unused and overly generic tag named
   "dynamic" for no discernible reason for many many years. After
   double-checking various distro source repositories, it has been
   removed.

   The refactoring is mostly non-functional changes, but should make the

This series adds a kernel boot parameter that causes the kernel to
 panic if one of the call_smp_function() APIs is stalled for more than
 the specified duration.  This is useful in deployments in which a clean

Linus Torvalds
eb55307e67 X86 core code updates: 
- Limit the hardcoded topology quirk for Hygon CPUs to those which have a
     model ID less than 4. The newer models have the topology CPUID leaf 0xB
     correctly implemented and are not affected.
 
   - Make SMT control more robust against enumeration failures
 
     SMT control was added to allow controlling SMT at boottime or
     runtime. The primary purpose was to provide a simple mechanism to
     disable SMT in the light of speculation attack vectors.
 
     It turned out that the code is sensible to enumeration failures and
     worked only by chance for XEN/PV. XEN/PV has no real APIC enumeration
     which means the primary thread mask is not set up correctly. By chance
     a XEN/PV boot ends up with smp_num_siblings == 2, which makes the
     hotplug control stay at its default value "enabled". So the mask is
     never evaluated.
 
     The ongoing rework of the topology evaluation caused XEN/PV to end up
     with smp_num_siblings == 1, which sets the SMT control to "not
     supported" and the empty primary thread mask causes the hotplug core to
     deny the bringup of the APS.
 
     Make the decision logic more robust and take 'not supported' and 'not
     implemented' into account for the decision whether a CPU should be
     booted or not.
 
   - Fake primary thread mask for XEN/PV
 
     Pretend that all XEN/PV vCPUs are primary threads, which makes the
     usage of the primary thread mask valid on XEN/PV. That is consistent
     with because all of the topology information on XEN/PV is fake or even
     non-existent.
 
   - Encapsulate topology information in cpuinfo_x86
 
     Move the randomly scattered topology data into a separate data
     structure for readability and as a preparatory step for the topology
     evaluation overhaul.
 
   - Consolidate APIC ID data type to u32
 
     It's fixed width hardware data and not randomly u16, int, unsigned long
     or whatever developers decided to use.
 
   - Cure the abuse of cpuinfo for persisting logical IDs.
 
     Per CPU cpuinfo is used to persist the logical package and die
     IDs. That's really not the right place simply because cpuinfo is
     subject to be reinitialized when a CPU goes through an offline/online
     cycle.
 
     Use separate per CPU data for the persisting to enable the further
     topology management rework. It will be removed once the new topology
     management is in place.
 
   - Provide a debug interface for inspecting topology information
 
     Useful in general and extremly helpful for validating the topology
     management rework in terms of correctness or "bug" compatibility.

Pull x86 core updates from Thomas Gleixner:

 - Limit the hardcoded topology quirk for Hygon CPUs to those which have
   a model ID less than 4.

   The newer models have the topology CPUID leaf 0xB correctly
   implemented and are not affected.

 - Make SMT control more robust against enumeration failures

   SMT control was added to allow controlling SMT at boottime or
   runtime. The primary purpose was to provide a simple mechanism to
   disable SMT in the light of speculation attack vectors.

   It turned out that the code is sensible to enumeration failures and
   worked only by chance for XEN/PV. XEN/PV has no real APIC enumeration
   which means the primary thread mask is not set up correctly. By
   chance a XEN/PV boot ends up with smp_num_siblings == 2, which makes
   the hotplug control stay at its default value "enabled". So the mask
   is never evaluated.

   The ongoing rework of the topology evaluation caused XEN/PV to end up
   with smp_num_siblings == 1, which sets the SMT control to "not
   supported" and the empty primary thread mask causes the hotplug core
   to deny the bringup of the APS.

   Make the decision logic more robust and take 'not supported' and 'not
   implemented' into account for the decision whether a CPU should be
   booted or not.

 - Fake primary thread mask for XEN/PV

   Pretend that all XEN/PV vCPUs are primary threads, which makes the
   usage of the primary thread mask valid on XEN/PV. That is consistent
   with because all of the topology information on XEN/PV is fake or
   even non-existent.

 - Encapsulate topology information in cpuinfo_x86

   Move the randomly scattered topology data into a separate data
   structure for readability and as a preparatory step for the topology
   evaluation overhaul.

 - Consolidate APIC ID data type to u32

   It's fixed width hardware data and not randomly u16, int, unsigned
   long or whatever developers decided to use.

 - Cure the abuse of cpuinfo for persisting logical IDs.

   Per CPU cpuinfo is used to persist the logical package and die IDs.
   That's really not the right place simply because cpuinfo is subject
   to be reinitialized when a CPU goes through an offline/online cycle.

   Use separate per CPU data for the persisting to enable the further
   topology management rework. It will be removed once the new topology
   management is in place.

 - Provide a debug interface for inspecting topology information

   Useful in general and extremly helpful for validating the topology
   management rework in terms of correctness or "bug" compatibility.

943af0e73a Updates for the X86 APIC: 
- Make the quirk for non-maskable MSI interrupts in the affinity setter
     functional again.
 
     It was broken by a MSI core code update, which restructured the code in
     a way that the quirk flag was not longer set correctly.
 
     Trying to restore the core logic caused a deeper inspection and it
     turned out that the extra quirk flag is not required at all because
     it's the inverse of the reservation mode bit, which only can be set
     when the MSI interrupt is maskable.
 
     So the trivial fix is to use the reservation mode check in the affinity
     setter function and remove almost 40 lines of code related to the
     no-mask quirk flag.
 
   - Cure a Kconfig dependency issue which causes compile fails by correcting
     the conditionals in the affected heaer files.
 
   - Clean up coding style in the UV APIC driver.

63a3f11975 Update for time, timekeeping and timers: 
Core:
 
    - Avoid superfluous deactivation of the tick in the low resolution tick
      NOHZ interrupt handler as the deactivation is handled already in the
      idle loop and on interrupt exit.
 
    - Update stale comments in the tick NOHZ code and rename the tick
      handler functions to be self-explanatory.
 
    - Remove an unused function in the tick NOHZ code, which was forgotten
      when the last user went away.
 
    - Handle RTC alarms which exceed the maximum alarm time of the
      underlying RTC hardware gracefully.
 
      Setting RTC alarms which exceed the maximum alarm time of the RTC
      hardware failed so far and caused suspend operations to abort.
 
      Cure this by limiting the alarm to the maximum alarm time of the RTC
      hardware, which is provided by the driver. This causes early resume
      wakeups, but that's way better than not suspending at all.
 
  Drivers:
 
    - Add a proper clocksource/event driver for the ancient Cirrus Logic
      EP93xx SoC family, which is one of the last non device-tree holdouts
      in arch/arm.
 
    - The usual boring device tree bindings updates and small fixes and
      enhancements all over the place.

9cc6fea175 Two small updates to ptrace_stop(): 
- Add a comment to explain that the preempt_disable() before unlocking
     tasklist lock is not a correctness problem and just avoids the tracer
     to preempt the tracee before the tracee schedules out.
 
   - Make that preempt_disable() conditional on PREEMPT_RT=n.
 
     RT enabled kernels cannot disable preemption at this point because
     cgroup_enter_frozen() and sched_submit_work() acquire spinlocks or
     rwlocks which are substituted by sleeping locks on RT. Acquiring a
     sleeping lock in a preemption disable region is obviously not possible.
 
     This obviously brings back the potential slowdown of ptrace() for RT
     enabled kernels, but that's a price to be payed for latency guarantees.

Pull core updates from Thomas Gleixner:
 "Two small updates to ptrace_stop():

   - Add a comment to explain that the preempt_disable() before
     unlocking tasklist lock is not a correctness problem and just
     avoids the tracer to preempt the tracee before the tracee schedules
     out.

   - Make that preempt_disable() conditional on PREEMPT_RT=n.

     RT enabled kernels cannot disable preemption at this point because
     cgroup_enter_frozen() and sched_submit_work() acquire spinlocks or
     rwlocks which are substituted by sleeping locks on RT. Acquiring a
     sleeping lock in a preemption disable region is obviously not
     possible.

     This obviously brings back the potential slowdown of ptrace() for
     RT enabled kernels, but that's a price to be paid for latency
     guarantees"
