Pull modules updates from Luis Chamberlain:
"Finally something fun. Mike Rapoport does some cleanup to allow us to
take out module_alloc() out of modules into a new paint shedded
execmem_alloc() and execmem_free() so to make emphasis these helpers
are actually used outside of modules.
It starts with a non-functional changes API rename / placeholders to
then allow architectures to define their requirements into a new shiny
struct execmem_info with ranges, and requirements for those ranges.
Archs now can intitialize this execmem_info as the last part of
mm_core_init() if they have to diverge from the norm. Each range is a
known type clearly articulated and spelled out in enum execmem_type.
Although a lot of this is major cleanup and prep work for future
enhancements an immediate clear gain is we get to enable KPROBES
without MODULES now. That is ultimately what motiviated to pick this
work up again, now with smaller goal as concrete stepping stone"

git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next
Pull networking updates from Jakub Kicinski:
"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).
- Ethernet high-speed NICs:
- Broadcom (bnxt):
- support multiple RSS contexts and steering traffic to them
- support XDP metadata
- make page pool allocations more NUMA aware
- Intel (100G, ice, idpf):

Pull interrupt subsystem updates from Thomas Gleixner:
"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"

allocation of KASAN shadow required by s390 and x86 and support for
late initialization of execmem required by arm64.
The core implementation of execmem_alloc() takes care of suppressing
warnings when the initial allocation fails but there is a fallback range
defined.

ARM: 9381/1: kasan: clear stale stack poison
|

Commit 9385/2 introduced a few branches inside function
prototypes when using CFI in order to deal with the situation
where CFI inserts a few bytes of function information in front
of the symbol.
This is not good for older CPUs where every cycle counts.
Commit 9386/2 alleviated the situation a bit by using aliases
for the cache functions with identical signatures.
This leaves the coherent cache flush functions
*_coherent_kern_range() with these branches to the corresponing
*_coherent_user_range() around, since their return type differ and
they therefore cannot be aliased.
Solve this by a simple ifdef so at least we can use fallthroughs
when compiling without CFI enabled.

CONFIG_BASE_FULL is equivalent to !CONFIG_BASE_SMALL and is enabled by
default: CONFIG_BASE_SMALL is the special case to take care of.
So, remove CONFIG_BASE_FULL and move the config choice to
CONFIG_BASE_SMALL (which defaults to 'n')
For defconfigs explicitely disabling BASE_FULL, explicitely enable
BASE_SMALL.
For defconfigs explicitely enabling BASE_FULL, drop it as it is the
default.

Since driver can parse num-cs device property, replace platform data
with this new approach. This pursues the following objectives:
- getting rid of the public header that barely used outside of
the SPI subsystem (more specifically the SPI PXA2xx drivers)
- making a trampoline for the driver to support non-default number
of the chip select pins in case the original code is going to be
converted to Device Tree model
It's not expected to have more users in board files except this one.

- Laurent converts the Raspberry Pi firmware DT binding to YAML, updates
the firmware driver to use the proper 'struct device' reference for
DMA mappings and drops unneeded properties from the DT node and
finishes by removing the duplicate firmware-clocks property to
bcm2835-rpi.dtsi. He also added support for the CAM1 camera interface
regulator.
- Uwe adds a pinctrl-based multiplexing description to allow the use of
I2C0 pins to allow usage between the 40-pin Raspberry Pi header and
the CSI and DSI connectors. He then describes the PCF85063 RTC device
available on the CM4 I/O board making use of that pinctrl-based
muxing.
- Arinc updates the Asus RT-AC3100 and RT-AC88U DTs to have proper LED
colors and function properties, NVMEM MAC addresses and removes
duplicates and unnecessary properties and does a few Device Tree
cleanups.. He then adds support for the Asus RT-AC3200 (BCM4709-based)
and RT-AC3500 routers.
- Jean-Michel adds DT nodes for the CSI Unicam camera interfaces on the
Raspberry Pi 4 / BCM2711 SoCs
- Florian adds support for the Ethernet LEDs on Raspberry Pi 4 B and

STM32 Firewall bus for v6.10, round 1
Highlights:
---------
Introduce STM32 Firewall framework for STM32MP1x and STM32MP2x
platforms. STM32MP1x(ETZPC) and STM32MP2x(RIFSC) Firewall controllers
register to the framework to offer firewall services such as access
granting.
This series of patches is a new approach on the previous STM32 system
bus, history is available here:
https://lore.kernel.org/lkml/20230127164040.1047583/
The need for such framework arises from the fact that there are now
multiple hardware firewalls implemented across multiple products.
Drivers are shared between different products, using the same code.
When it comes to firewalls, the purpose mostly stays the same: Protect
hardware resources. But the implementation differs, and there are
multiple types of firewalls: peripheral, memory, ...
Some hardware firewall controllers such as the RIFSC implemented on
STM32MP2x platforms may require to take ownership of a resource before
being able to use it, hence the requirement for firewall services to
take/release the ownership of such resources.
On the other hand, hardware firewall configurations are becoming
more and more complex. These mecanisms prevent platform crashes
or other firewall-related incoveniences by denying access to some
resources.
The stm32 firewall framework offers an API that is defined in
firewall controllers drivers to best fit the specificity of each
firewall.
For every peripherals protected by either the ETZPC or the RIFSC, the
firewall framework checks the firewall controlelr registers to see if
the peripheral's access is granted to the Linux kernel. If not, the
peripheral is configured as secure, the node is marked populated,
so that the driver is not probed for that device.
The firewall framework relies on the access-controller device tree
binding. It is used by peripherals to reference a domain access
controller. In this case a firewall controller. The bus uses the ID
referenced by the access-controller property to know where to look
in the firewall to get the security configuration for the peripheral.
This allows a device tree description rather than a hardcoded peripheral
table in the bus driver.
The STM32 ETZPC device is responsible for filtering accesses based on
security level, or co-processor isolation for any resource connected
to it.
The RIFSC is responsible for filtering accesses based on Compartment
ID / security level / privilege level for any resource connected to
it.

Support Control Flow Integrity (CFI) when compiling with
CLANG.
In the as-of-writing LLVM CLANG implementation (v17)
the 32-bit ARM platform is supported by the generic CFI
implementation, which isn't tailored specifically for ARM32
but works well enough to enable the feature.

This registers a breakpoint handler for the new breakpoint type
(0x03) inserted by LLVM CLANG for CFI breakpoints.
If we are in permissive mode, just print a backtrace and continue.
Example with CONFIG_CFI_PERMISSIVE enabled:
> echo CFI_FORWARD_PROTO > /sys/kernel/debug/provoke-crash/DIRECT
lkdtm: Performing direct entry CFI_FORWARD_PROTO
lkdtm: Calling matched prototype ...
lkdtm: Calling mismatched prototype ...
CFI failure at lkdtm_indirect_call+0x40/0x4c (target: 0x0; expected type: 0x00000000)
WARNING: CPU: 1 PID: 112 at lkdtm_indirect_call+0x40/0x4c
CPU: 1 PID: 112 Comm: sh Not tainted 6.8.0-rc1+ #150
Hardware name: ARM-Versatile Express
(...)
lkdtm: FAIL: survived mismatched prototype function call!
lkdtm: Unexpected! This kernel (6.8.0-rc1+ armv7l) was built with CONFIG_CFI_CLANG=y
As you can see the LKDTM test fails, but I expect that this would be
expected behaviour in the permissive mode.
We are currently not implementing target and type for the CFI
breakpoint as this requires additional operand bundling compiler
extensions.
CPUs without breakpoint support cannot handle breakpoints naturally,
in these cases the permissive mode will not work, CFI will fall over
on an undefined instruction:
Internal error: Oops - undefined instruction: 0 [#1] PREEMPT ARM
CPU: 0 PID: 186 Comm: ash Tainted: G W 6.9.0-rc1+ #7
Hardware name: Gemini (Device Tree)
PC is at lkdtm_indirect_call+0x38/0x4c
LR is at lkdtm_CFI_FORWARD_PROTO+0x30/0x6c
This is reasonable I think: it's the best CFI can do to ascertain
the the control flow is not broken on these CPUs.

When we annotate the loop delay code with SYM_TYPED_FUNC_START()
a function prototype signature will be emitted into the object
file above each site called from C, and the delay loop code is
using "fallthroughs" from the different assembly callbacks. This
will not work as the execution flow will run into the prototype
signatures.
Rewrite the code to use explicit branches to the other code
segments and annotate the code using SYM_TYPED_FUNC_START().
Tested on the ARM Versatile which uses the calibrated loop delay.

Each CPU type ("proc") has assembly calls for initializing and
setting up the MM context, idle and so forth.
These calls have the C form of e.g.:
void cpu_arm920_init(void);
However this prototype is not really specified, instead it is
generated by the glue code in <asm/glue-proc.h> and the prototype
is implicit from the generic prototype defined in <asm/proc-fns.h>
such as cpu_proc_init() in this case. (This is a bit similar to
the "interface" or inheritance concept in other languages.)
To be able to annotate these assembly calls for CFI, they all need
to have a proper C prototype per CPU call.
Define these in a new C file that is only compiled when we use
CFI, and add __ADDRESSABLE() to each so the compiler knows that
these will be addressed (they are not explicitly called in C, they
are called by way of cpu_proc_init() etc).
It is a bit of definitions, but we do not expect new ARM32 CPUs
to appear very much so it should be pretty static.

Type tag the remaining per-processor assembly using the CFI
symbol macros, in addition to those that were previously tagged
for cache maintenance calls.
This will be used to finally provide proper C prototypes for
all these calls as well so that CFI can be made to work.

Instead of defining all cache flush operations with an assembly
macro in proc-macros.S, provide an explicit struct cpu_cache_fns
for each CPU cache type in mm/cache.c.
As a side effect from rewriting the vtables in C, we can
avoid the aliasing for the "louis" cache callback, instead we
can just assign the NN_flush_kern_cache_all() function to the
louis callback in the C vtable.
As the louis cache callback is called explicitly (not through the
vtable) if we only have one type of cache support compiled in, we
need an ifdef quirk for this in the !MULTI_CACHE case.
Feroceon and XScale have some dma mapping quirk, in this case we
can just define two structs and assign all but one callback to the
main implementation; since each of them invoked define_cache_functions
twice they require MULTI_CACHE by definition so the compiled-in
shortcut is not used on these variants.

The cache functions to flush user cache (*_flush_user_cache_all)
are in many cases just a branch to the corresponfing userspace or
kernelspace function. These functions also have the same arguments.
Simplify these by using SYM_FUNC_ALIAS() in all affected sites.
The NOP cache has very many similar calls which are just returns,
but it would be confusing to use aliases here, so leave all the
explicit returns and drop a comment on why we are not using aliases.
