Pull devicetree updates from Rob Herring:
"DT core:
- Add support for generating DT nodes for PCI devices. This is the
groundwork for applying overlays to PCI devices containing
non-discoverable downstream devices.
- DT unittest additions to check reverted changesets, to test for
refcount issues, and to test unresolved symbols. Also, various
clean-ups of the unittest along the way.
- Refactor node and property manipulation functions to better share
code with old API and changeset API
- Refactor changeset print functions to a common implementation
- Move some platform_device specific functions into of_platform.c
Bindings:
- Treewide fixing of typos
- Treewide clean-up of SPDX tags to use 'OR' consistently
- Last chunk of dropping unnecessary quotes. With that, the check for
unnecessary quotes is enabled in yamllint.
- Convert ftgmac100, zynqmp-genpd, pps-gpio, syna,rmi4, and qcom,ssbi
bindings to DT schema format
- Add Allwinner V3s xHCI USB, Saef SF-TC154B display, QCom SM8450
Inline Crypto Engine, QCom SM6115 UFS, QCom SDM670 PDC interrupt
controller, Arm 2022 Cortex cores, and QCom IPQ9574 Crypto bindings
- Fixes for Rockchip DWC PCI binding
- Ensure all properties are evaluated on USB connector schema
- Fix dt-check-compatible script to find of_device_id instances with
compiler annotations"

"These are the devicetree updates for Arm and RISC-V based SoCs, mainly
from Qualcomm, NXP/Freescale, Aspeed, TI, Rockchips, Samsung, ST and
Starfive.
Only a few new SoC got added:
- TI AM62P5, a variant of the existing Sitara AM62x family
- Intel Agilex5, an FPGFA platform that includes an Cortex-A76/A55
SoC.
- Qualcomm ipq5018 is used in wireless access points
- Qualcomm SM4450 (Snapdragon 4 Gen 2) is a new low-end mobile phone
platform.
In total, 29 machines get added, which is low because of the summer
break. These cover SoCs from Aspeed, Broadcom, NXP, Samsung, ST,
Allwinner, Amlogic, Intel, Qualcomm, Rockchip, TI and T-Head. Most of
these are development and reference boards.
Despite not adding a lot of new machines, there are over 700 patches

ALSA / ASoC Core:
- Fixes of inconsistent locking around control API helpers
- A few new control API functions and cleanups
- Workarounds for potential UAFs by delayed kobj releases
- Unified PCM copy ops with iov_iter
- Continued efforts for ASoC API cleanups
ASoC:
- An adaptor to allow use of IIO DACs and ADCs in ASoC which pulls in
some IIO changes
- Create a library function for intlog10() and use it in the NAU8825
driver
- Convert drivers to use the more modern maple tree register cache
- Lots of work on the SOF framework, AMD and Intel drivers, including
a lot of cleanup and new device support
- Standardization of the presentation of jacks from drivers
- Provision of some generic sound card DT properties
- Support for AMD Van Gogh, AMD machines with MAX98388 and NAU8821,

- New test coverage including ASoC and topology tests in KUnit; this
also involves enabling UML builds of ALSA since that's the default
KUnit test environment which pulls in the addition of some stubs to
the driver
- More enhancement of pcmtest driver
- A few fixes / enhancements of MIDI 2.0 UMP core
- Using PCI definitions in allover HD-audio code

x86: bring back rep movsq for user access on CPUs without ERMS
Intel CPUs ship with ERMS for over a decade, but this is not true for
AMD. In particular one reasonably recent uarch (EPYC 7R13) does not
have it (or at least the bit is inactive when running on the Amazon EC2
cloud -- I found rather conflicting information about AMD CPUs vs the
extension).
Hand-rolled mov loops executing in this case are quite pessimal compared
to rep movsq for bigger sizes. While the upper limit depends on uarch,
everyone is well south of 1KB AFAICS and sizes bigger than that are
common.
While technically ancient CPUs may be suffering from rep usage, gcc has
been emitting it for years all over kernel code, so I don't think this
is a legitimate concern.
Sample result from read1_processes from will-it-scale (4KB reads/s):
before:
1507021
after:
1721828 (+14%)
Note that the cutoff point for rep usage is set to 64 bytes, which is
way too conservative but I'm sticking to what was done in
47ee3f1dd93b
("x86: re-introduce support for ERMS copies for user space accesses").
That is to say *some* copies will now go slower, which is fixable but
beyond the scope of this patch.

- Add proper multi-LSM support for xattrs in the
security_inode_init_security() hook
Historically the LSM layer has only allowed a single LSM to add an
xattr to an inode, with IMA/EVM measuring that and adding its own as
well. As we work towards promoting IMA/EVM to a "proper LSM" instead
of the special case that it is now, we need to better support the
case of multiple LSMs each adding xattrs to an inode and after
several attempts we now appear to have something that is working
well. It is worth noting that in the process of making this change we
uncovered a problem with Smack's SMACK64TRANSMUTE xattr which is also
fixed in this pull request.
- Additional LSM hook constification
Two patches to constify parameters to security_capget() and
security_binder_transfer_file(). While I generally don't make a
special note of who submitted these patches, these were the work of
an Outreachy intern, Khadija Kamran, and that makes me happy;
hopefully it does the same for all of you reading this.

typo.

obviously correct, and arguably the LSM layer has a vested interest

Pull selinux updates from Paul Moore:
"Thirty three SELinux patches, which is a pretty big number for us, but
there isn't really anything scary in here; in fact we actually manage
to remove 10 lines of code with this :)
- Promote the SELinux DEBUG_HASHES macro to CONFIG_SECURITY_SELINUX_DEBUG
The DEBUG_HASHES macro was a buried SELinux specific preprocessor
debug macro that was a problem waiting to happen. Promoting the
debug macro to a proper Kconfig setting should help both improve
the visibility of the feature as well enable improved test
coverage. We've moved some additional debug functions under the
CONFIG_SECURITY_SELINUX_DEBUG flag and we may see more work in the
future.
- Emit a pr_notice() message if virtual memory is executable by default
As this impacts the SELinux access control policy enforcement, if
the system's configuration is such that virtual memory is
executable by default we print a single line notice to the console.
- Drop avtab_search() in favor of avtab_search_node()
Both functions are nearly identical so we removed avtab_search()
and converted the callers to avtab_search_node().
- Add some SELinux network auditing helpers
The helpers not only reduce a small amount of code duplication, but
they provide an opportunity to improve UDP flood performance
slightly by delaying initialization of the audit data in some
cases.
- Convert GFP_ATOMIC allocators to GFP_KERNEL when reading SELinux policy
There were two SELinux policy load helper functions that were
allocating memory using GFP_ATOMIC, they have been converted to
GFP_KERNEL.
- Quiet a KMSAN warning in selinux_inet_conn_request()
A one-line error path (re)set patch that resolves a KMSAN warning.
It is important to note that this doesn't represent a real bug in
the current code, but it quiets KMSAN and arguably hardens the code
against future changes.
- Cleanup the policy capability accessor functions
This is a follow-up to the patch which reverted SELinux to using a
global selinux_state pointer. This patch cleans up some artifacts
of that change and turns each accessor into a one-line READ_ONCE()
call into the policy capabilities array.
- A number of patches from Christian Göttsche
Christian submitted almost two-thirds of the patches in this pull
request as he worked to harden the SELinux code against type
differences, variable overflows, etc.
- Support for separating early userspace from the kernel in policy,
with a later revert
We did have a patch that added a new userspace initial SID which
would allow SELinux to distinguish between early user processes
created before the initial policy load and the kernel itself.
Unfortunately additional post-merge testing revealed a problematic
interaction with an old SELinux userspace on an old version of
Ubuntu so we've reverted the patch until we can resolve the
compatibility issue.
- Remove some outdated comments dealing with LSM hook registration
When we removed the runtime disable functionality we forgot to
remove some old comments discussing the importance of LSM hook
registration ordering.
- Minor administrative changes
Stephen Smalley updated his email address and "debranded" SELinux
from "NSA SELinux" to simply "SELinux". We've come a long way from
the original NSA submission and I would consider SELinux a true
community project at this point so removing the NSA branding just
makes sense"

works to process all of these new entries.
This is in sharp contrast to the common case where only one or two

excessively impacting the common case we're adding a single
cond_rescued() call between two of the most intensive loops in the

"Long ago we set out to remove the kitchen sink on kernel/sysctl.c
arrays and placings sysctls to their own sybsystem or file to help
avoid merge conflicts. Matthew Wilcox pointed out though that if we're
going to do that we might as well also *save* space while at it and
try to remove the extra last sysctl entry added at the end of each
array, a sentintel, instead of bloating the kernel by adding a new
sentinel with each array moved.
Doing that was not so trivial, and has required slowing down the moves
of kernel/sysctl.c arrays and measuring the impact on size by each new
move.
The complex part of the effort to help reduce the size of each sysctl
is being done by the patient work of el señor Don Joel Granados. A lot
of this is truly painful code refactoring and testing and then trying
to measure the savings of each move and removing the sentinels.
Although Joel already has code which does most of this work,
experience with sysctl moves in the past shows is we need to be
careful due to the slew of odd build failures that are possible due to
the amount of random Kconfig options sysctls use.
To that end Joel's work is split by first addressing the major
housekeeping needed to remove the sentinels, which is part of this
merge request. The rest of the work to actually remove the sentinels
will be done later in future kernel releases.
The preliminary math is showing this will all help reduce the overall
build time size of the kernel and run time memory consumed by the
kernel by about ~64 bytes per array where we are able to remove each
sentinel in the future. That also means there is no more bloating the
kernel with the extra ~64 bytes per array moved as no new sentinels
are created"

Pull modules updates from Luis Chamberlain:
"Summary of the changes worth highlighting from most interesting to
boring below:
- Christoph Hellwig's symbol_get() fix to Nvidia's efforts to
circumvent the protection he put in place in year 2020 to prevent
proprietary modules from using GPL only symbols, and also ensuring
proprietary modules which export symbols grandfather their taint.
That was done through year 2020 commit
262e6ae7081d ("modules:
inherit TAINT_PROPRIETARY_MODULE"). Christoph's new fix is done by
clarifing __symbol_get() was only ever intended to prevent module
reference loops by Linux kernel modules and so making it only find
symbols exported via EXPORT_SYMBOL_GPL(). The circumvention tactic
used by Nvidia was to use symbol_get() to purposely swift through
proprietary module symbols and completely bypass our traditional
EXPORT_SYMBOL*() annotations and community agreed upon
restrictions.
A small set of preamble patches fix up a few symbols which just
needed adjusting for this on two modules, the rtc ds1685 and the
networking enetc module. Two other modules just needed some build
fixing and removal of use of __symbol_get() as they can't ever be
modular, as was done by Arnd on the ARM pxa module and Christoph
did on the mmc au1xmmc driver.
This is a good reminder to us that symbol_get() is just a hack to
address things which should be fixed through Kconfig at build time
as was done in the later patches, and so ultimately it should just
go.
- Extremely late minor fix for old module layout
055f23b74b20
("module: check for exit sections in layout_sections() instead of
module_init_section()") by James Morse for arm64. Note that this
layout thing is old, it is *not* Song Liu's commit
ac3b43283923
("module: replace module_layout with module_memory"). The issue
however is very odd to run into and so there was no hurry to get
this in fast.
- Although the fix did not go through the modules tree I'd like to
highlight the fix by Peter Zijlstra in commit
54097309620e
("x86/static_call: Fix __static_call_fixup()") now merged in your
tree which came out of what was originally suspected to be a
fallout of the the newer module layout changes by Song Liu commit
ac3b43283923 ("module: replace module_layout with module_memory")
instead of module_init_section()"). Thanks to the report by
Christian Bricart and the debugging by Song Liu & Peter that turned
to be noted as a kernel regression in place since v5.19 through
commit
ee88d363d156 ("x86,static_call: Use alternative RET
encoding").
I highlight this to reflect and clarify that we haven't seen more
fallout from
ac3b43283923 ("module: replace module_layout with
module_memory").
- RISC-V toolchain got mapping symbol support which prefix symbols
with "$" to help with alignment considerations for disassembly.
This is used to differentiate between incompatible instruction
encodings when disassembling. RISC-V just matches what ARM/AARCH64
did for alignment considerations and Palmer Dabbelt extended
is_mapping_symbol() to accept these symbols for RISC-V. We already
had support for this for all architectures but it also checked for
the second character, the RISC-V check Dabbelt added was just for
the "$". After a bit of testing and fallout on linux-next and based
on feedback from Masahiro Yamada it was decided to simplify the
check and treat the first char "$" as unique for all architectures,
and so we no make is_mapping_symbol() for all archs if the symbol
starts with "$".
The most relevant commit for this for RISC-V on binutils was:
https://sourceware.org/pipermail/binutils/2021-July/117350.html
- A late fix by Andrea Righi (today) to make module zstd
decompression use vmalloc() instead of kmalloc() to account for
large compressed modules. I suspect we'll see similar things for
other decompression algorithms soon.

Chen Jiahao"

Merge tag 'rust-6.6' of https://github.com/Rust-for-Linux/linux
Pull rust updates from Miguel Ojeda:
"In terms of lines, most changes this time are on the pinned-init API
and infrastructure. While we have a Rust version upgrade, and thus a
bunch of changes from the vendored 'alloc' crate as usual, this time
those do not account for many lines.
Toolchain and infrastructure:
- Upgrade to Rust 1.71.1. This is the second such upgrade, which is a
smaller jump compared to the last time.
This version allows us to remove the '__rust_*' allocator functions
-- the compiler now generates them as expected, thus now our
'KernelAllocator' is used.
It also introduces the 'offset_of!' macro in the standard library
(as an unstable feature) which we will need soon. So far, we were
using a declarative macro as a prerequisite in some not-yet-landed
patch series, which did not support sub-fields (i.e. nested
structs):
#[repr(C)]
struct S {
a: u16,
b: (u8, u8),
}
assert_eq!(offset_of!(S, b.1), 3);
- Upgrade to bindgen 0.65.1. This is the first time we upgrade its
version.
Given it is a fairly big jump, it comes with a fair number of
improvements/changes that affect us, such as a fix needed to
support LLVM 16 as well as proper support for '__noreturn' C
functions, which are now mapped to return the '!' type in Rust:
void __noreturn f(void); // C
pub fn f() -> !; // Rust
- 'scripts/rust_is_available.sh' improvements and fixes.
This series takes care of all the issues known so far and adds a
few new checks to cover for even more cases, plus adds some more
help texts. All this together will hopefully make problematic
setups easier to identify and to be solved by users building the
kernel.
In addition, it adds a test suite which covers all branches of the
shell script, as well as tests for the issues found so far.
- Support rust-analyzer for out-of-tree modules too.
- Give 'cfg's to rust-analyzer for the 'core' and 'alloc' crates.
- Drop 'scripts/is_rust_module.sh' since it is not needed anymore.
Macros crate:
- New 'paste!' proc macro.
This macro is a more flexible version of 'concat_idents!': it
allows the resulting identifier to be used to declare new items and
it allows to transform the identifiers before concatenating them,
e.g.
let x_1 = 42;
paste!(let [<x _2>] = [<x _1>];);
assert!(x_1 == x_2);
The macro is then used for several of the pinned-init API changes
in this pull.
Pinned-init API:
- Make '#[pin_data]' compatible with conditional compilation of
fields, allowing to write code like:
#[pin_data]
pub struct Foo {
#[cfg(CONFIG_BAR)]
a: Bar,
#[cfg(not(CONFIG_BAR))]
a: Baz,
}
- New '#[derive(Zeroable)]' proc macro for the 'Zeroable' trait,
which allows 'unsafe' implementations for structs where every field
implements the 'Zeroable' trait, e.g.:
#[derive(Zeroable)]
pub struct DriverData {
id: i64,
buf_ptr: *mut u8,
len: usize,
}
- Add '..Zeroable::zeroed()' syntax to the 'pin_init!' macro for
zeroing all other fields, e.g.:
pin_init!(Buf {
buf: [1; 64],
..Zeroable::zeroed()
});
- New '{,pin_}init_array_from_fn()' functions to create array
initializers given a generator function, e.g.:
let b: Box<[usize; 1_000]> = Box::init::<Error>(
init_array_from_fn(|i| i)
).unwrap();
assert_eq!(b.len(), 1_000);
assert_eq!(b[123], 123);
- New '{,pin_}chain' methods for '{,Pin}Init<T, E>' that allow to
execute a closure on the value directly after initialization, e.g.:
let foo = init!(Foo {
buf <- init::zeroed()
}).chain(|foo| {
foo.setup();
Ok(())
});
- Support arbitrary paths in init macros, instead of just identifiers
and generic types.
- Implement the 'Zeroable' trait for the 'UnsafeCell<T>' and
'Opaque<T>' types.
- Make initializer values inaccessible after initialization.
- Make guards in the init macros hygienic.
'allocator' module:
- Use 'krealloc_aligned()' in 'KernelAllocator::alloc' preventing
misaligned allocations when the Rust 1.71.1 upgrade is applied
later in this pull.
The equivalent fix for the previous compiler version (where
'KernelAllocator' is not yet used) was merged into 6.5 already,
which added the 'krealloc_aligned()' function used here.
- Implement 'KernelAllocator::{realloc, alloc_zeroed}' for
performance, using 'krealloc_aligned()' too, which forwards the
call to the C API.
'types' module:
- Make 'Opaque' be '!Unpin', removing the need to add a
'PhantomPinned' field to Rust structs that contain C structs which
must not be moved.
- Make 'Opaque' use 'UnsafeCell' as the outer type, rather than
inner.
Documentation:
- Suggest obtaining the source code of the Rust's 'core' library
using the tarball instead of the repository.

ALSA: pcm: Fix missing fixup call in compat hw_refine ioctl
The update of rate_num/den and msbits were factored out to
fixup_unreferenced_params() function to be called explicitly after the
hw_refine or hw_params procedure. It's called from
snd_pcm_hw_refine_user(), but it's forgotten in the PCM compat ioctl.
This ended up with the incomplete rate_num/den and msbits parameters
when 32bit compat ioctl is used.
This patch adds the missing call in snd_pcm_ioctl_hw_params_compat().

Merge branch 'slab/for-6.6/random_kmalloc' into slab/for-next
Merge the new hardening feature to make heap spraying harder, by GONG,
Ruiqi. It creates multiple (16) copies of kmalloc caches, reducing the
chance of an attacker-controllable allocation site to land in the same
slab as e.g. an allocation site with use-after-free vulnerability. The
selection of the copy is derived from the allocation site address,
including a per-boot random seed.
In line with SLAB deprecation, this is a SLUB only feature, incompatible
with SLUB_TINY due to the memory overhead of the extra cache copies.

super: ensure valid info
For keyed filesystems that recycle superblocks based on s_fs_info or
information contained therein s_fs_info must be kept as long as the
superblock is on the filesystem type super list. This isn't guaranteed
as s_fs_info will be freed latest in sb->kill_sb().
The fix is simply to perform notification and list removal in
kill_anon_super(). Any filesystem needs to free s_fs_info after they
call the kill_*() helpers. If they don't they risk use-after-free right
now so fixing it here is guaranteed that s_fs_info remain valid.
For block backed filesystems notifying in pass sb->kill_sb() in
deactivate_locked_super() remains unproblematic and is required because
multiple other block devices can be shut down after kill_block_super()
has been called from a filesystem's sb->kill_sb() handler. For example,
ext4 and xfs close additional devices. Block based filesystems don't
depend on s_fs_info (btrfs does use s_fs_info but also uses
kill_anon_super() and not kill_block_super().).
Sorry for that braino. Goal should be to unify this behavior during this
cycle obviously. But let's please do a simple bugfix now.

Merge tag 'sched-core-2023-08-28' of git://git./linux/kernel/git/tip/tip
Pull scheduler updates from Ingo Molnar:
- The biggest change is introduction of a new iteration of the
SCHED_FAIR interactivity code: the EEVDF ("Earliest Eligible Virtual
Deadline First") scheduler
EEVDF too is a virtual-time scheduler, with two parameters (weight
and relative deadline), compared to CFS that had weight only. It
completely reworks the base scheduler: placement, preemption, picking
-- everything
LWN.net, as usual, has a terrific writeup about EEVDF:
https://lwn.net/Articles/925371/
Preemption (both tick and wakeup) is driven by testing against a
fresh pick. Because the tree is now effectively an interval tree, and
the selection is no longer the 'leftmost' task, over-scheduling is
less of a problem. A lot of the CFS heuristics are removed or
replaced by more natural latency-space parameters & constructs
In terms of expected performance regressions: we will and can fix
everything where a 'good' workload misbehaves with the new scheduler,
but EEVDF inevitably changes workload scheduling in a binary fashion,
hopefully for the better in the overwhelming majority of cases, but
in some cases it won't, especially in adversarial loads that got
lucky with the previous code, such as some variants of hackbench. We
are trying hard to err on the side of fixing all performance
regressions, but we expect some inevitable post-release iterations of
that process
- Improve load-balancing on hybrid x86 systems: enable cluster
scheduling (again)
- Improve & fix bandwidth-scheduling on nohz systems
- Improve bandwidth-throttling
- Use lock guards to simplify and de-goto-ify control flow

"Avoid the baremetal decompressor code when booting on an EFI machine.
This is mandated by the current tightening of EFI executables
requirements when used in a secure boot scenario. More specifically,
an EFI executable cannot have a single section with RWX permissions,
which conflicts with the in-place kernel decompression that is done
today.
Instead, the things required by the booting kernel image are done in
the EFI stub now.

Pull CPU hotplug updates from Thomas Gleixner:
"Updates for the CPU hotplug core:
- Support partial SMT enablement.
So far the sysfs SMT control only allows to toggle between SMT on
and off. That's sufficient for x86 which usually has at max two
threads except for the Xeon PHI platform which has four threads per
core
Though PowerPC has up to 16 threads per core and so far it's only
possible to control the number of enabled threads per core via a
command line option. There is some way to control this at runtime,
but that lacks enforcement and the usability is awkward
This update expands the sysfs interface and the core infrastructure
to accept numerical values so PowerPC can build SMT runtime control
for partial SMT enablement on top
The core support has also been provided to the PowerPC maintainers
who added the PowerPC related changes on top
- Minor cleanups and documentation updates"

Fixes:
- scrub performance drop due to rewrite in 6.4 partially restored:
- do IO grouping by blg_plug/blk_unplug again
- avoid unnecessary tree searches when processing stripes, in
extent and checksum trees
- the drop is noticeable on fast PCIe devices, -66% and restored
to -33% of the original
- backports to 6.4 planned
- handle more corner cases of transaction commit during orphan
cleanup or delayed ref processing
- use correct fsid/metadata_uuid when validating super block
- copy directory permissions and time when creating a stub subvolume
Core:
- debugging feature integrity checker deprecated, to be removed in
6.7
- in zoned mode, zones are activated just before the write, making
error handling easier, now the overcommit mechanism can be enabled
again which improves performance by avoiding more frequent flushing
- v0 extent handling completely removed, deprecated long time ago
