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

but only a few new driver specific features. The bulk of the changes in
terms of diffstat are the cleanups, plus one bit of performance work for
McSPI.
- Conversions to use devm_clk_get_enabled() and to remove outdated
terms for controller and device.
- Device mode support for the Renesas CSI.
- Cleanups and improvements to the device tree bindings aimed at making
validation better.
- PIO FIFO usage for the OMAP2 McSPI, improving performance.

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()
- remove unused acpi_get_and_request_gpiod()
- improve the ignore_interrupt functionality in GPIO ACPI
- correct notifier return codes in gpiolib-of

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.

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 'rust-6.7' of https://github.com/Rust-for-Linux/linux
Pull rust updates from Miguel Ojeda:
"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"

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.

RCU pull request for v6.7
This pull request contains the following branches:
rcu/torture: RCU torture, locktorture and generic torture infrastructure
updates that include various fixes, cleanups and consolidations.
Among the user visible things, ftrace dumps can now be found into
their own file, and module parameters get better documented and
reported on dumps.

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.

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.

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.

Pull timer updates from Thomas Gleixner:
"Updates 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"

Updates for SMP and CPU hotplug:
- Switch the smp_call_function*() @csd argument to call_single_data_t
type, which is a cache-line aligned typedef of the underlying struct
__call_single_data.
This ensures that the call data is not crossing a cacheline which
avoids bouncing an extra cache-line for the SMP function call
- Prevent offlining of the last housekeeping CPU when CPU isolation is
active.
Offlining the last housekeeping CPU makes no sense in general, but also
caused the scheduler to panic due to the empty CPU mask when rebuilding
the scheduler domains.
- Remove an unused CPU hotplug state

Updates for the interrupt subsytem:
Core:
- Exclude managed interrupts in the calculation of interrupts which are
targeted to a CPU which is about to be offlined to ensure that there
are enough free vectors on the still online CPUs to migrate them over.
Managed interrupts do not need to be accounted because they are
either shut down on offline or migrated to an already reserved and
guaranteed slot on a still online CPU in the interrupts affinity
mask.
Including managed interrupts is overaccounting and can result in
needlessly aborting hibernation on large server machines.
- The usual set of small improvements
Drivers:
- Make the generic interrupt chip implementation handle interrupt
domains correctly and initialize the name pointers correctly
- Add interrupt affinity setting support to the Renesas RZG2L chip
driver.
- Prevent registering syscore operations multiple times in the SiFive
PLIC chip driver.
- Update device tree handling in the NXP Layerscape MSI chip driver

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.

- Add the 'futex2' syscall ABI, which is an attempt to get away from the
multiplex syscall and adds a little room for extentions, while lifting
some limitations.
- Fix futex PI recursive rt_mutex waiter state bug
- Fix inter-process shared futexes on no-MMU systems
- Use folios instead of pages
- Micro-optimizations of locking primitives:
- Improve arch_spin_value_unlocked() on asm-generic ticket spinlock
architectures, to improve lockref code generation.
- Improve the x86-32 lockref_get_not_zero() main loop by adding
build-time CMPXCHG8B support detection for the relevant lockref code,
and by better interfacing the CMPXCHG8B assembly code with the compiler.
- Introduce arch_sync_try_cmpxchg() on x86 to improve sync_try_cmpxchg()
code generation. Convert some sync_cmpxchg() users to sync_try_cmpxchg().
- Micro-optimize rcuref_put_slowpath()
- Locking debuggability improvements:
- Improve CONFIG_DEBUG_RT_MUTEXES=y to have a fast-path as well
- Enforce atomicity of sched_submit_work(), which is de-facto atomic but
was un-enforced previously.
- Extend <linux/cleanup.h>'s no_free_ptr() with __must_check semantics
- Fix ww_mutex self-tests
- Clean up const-propagation in <linux/seqlock.h> and simplify
the API-instantiation macros a bit.
- RT locking improvements:
- Provide the rt_mutex_*_schedule() primitives/helpers and use them
in the rtmutex code to avoid recursion vs. rtlock on the PI state.
- Add nested blocking lockdep asserts to rt_mutex_lock(), rtlock_lock()
and rwbase_read_lock().
- Plus misc fixes & cleanups
