Pull x86 shadow stack support from Dave Hansen:
"This is the long awaited x86 shadow stack support, part of Intel's
Control-flow Enforcement Technology (CET).
CET consists of two related security features: shadow stacks and
indirect branch tracking. This series implements just the shadow stack
part of this feature, and just for userspace.
The main use case for shadow stack is providing protection against
return oriented programming attacks. It works by maintaining a
secondary (shadow) stack using a special memory type that has
protections against modification. When executing a CALL instruction,
the processor pushes the return address to both the normal stack and
to the special permission shadow stack. Upon RET, the processor pops
the shadow stack copy and compares it to the normal stack copy.
For more information, refer to the links below for the earlier
versions of this patch set"

"On top of the vfio updates is built some new iommufd functionality:
- IOMMU_HWPT_ALLOC allows userspace to directly create the low level
IO Page table objects and affiliate them with IOAS objects that
hold the translation mapping. This is the basic functionality for
the normal IOMMU_DOMAIN_PAGING domains.
- VFIO_DEVICE_ATTACH_IOMMUFD_PT can be used to replace the current
translation. This is wired up to through all the layers down to the
driver so the driver has the ability to implement a hitless
replacement. This is necessary to fully support guest behaviors
when emulating HW (eg guest atomic change of translation)
- IOMMU_GET_HW_INFO returns information about the IOMMU driver HW
that owns a VFIO device. This includes support for the Intel iommu,
and patches have been posted for all the other server IOMMU.
Along the way are a number of internal items:
- New iommufd kernel APIs: iommufd_ctx_has_group(),
iommufd_device_to_ictx(), iommufd_device_to_id(),
iommufd_access_detach(), iommufd_ctx_from_fd(),
iommufd_device_replace()
- iommufd now internally tracks iommu_groups as it needs some
per-group data
- Reorganize how the internal hwpt allocation flows to have more
robust locking
- Improve the access interfaces to support detach and replace of an
IOAS from an access
- New selftests and a rework of how the selftests creates a mock

"This pull request is full of clk driver changes. In fact, there aren't
any changes to the clk framework this time around. That's probably
because everyone was on vacation (yours truly included). We did lose a
couple clk drivers this time around because nobody was using those

out of the ordinary here. The usual suspects are chugging along adding
support for more SoCs and fixing bugs.
If I had to choose, I'd say the theme for the past few months has been
"polish". There's quite a few patches that migrate to
devm_platform_ioremap_resource() in here. And there's more than a
handful of patches that move the NR_CLKS define from the DT binding
header to the driver. There's even patches that migrate drivers to use
clk_parent_data and clk_hw to describe clk tree topology. It seems
that the spring (summer?) cleaning bug got some folks, or the
semiconductor shortage finally hit the software side.

No core changes this time.
Drivers:
- Intel Tangier SoC pin control support
- AMLogic C3 SoC pin control support
- Texas Instruments AM654 SoC pin control support
- Qualcomm SM8350 and SM6115 LPASS (Low Power Audio Sub-System) pin

- DROP the Oxnas driver as there is not enough of community interest
to keep carrying this ARM(11) port
Enhancements:
- Bias control in the MT7986 pin control driver
- Misc device tree binding enhancements such as the Broadcom 11351
being converted to YAML
- New macro: DEFINE_NOIRQ_DEV_PM_OPS() put to use
- Clean up some SPDX headers

Pull sound updates from Takashi Iwai:
"We've received a fairly wide range of changes at this time, including
for ALSA and ASoC core, but all of them are rather small changes.
Here are some highlights:
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,
AWInic AW88261, Cirrus Logic CS35L36 and CS42L43, various Intel
platforms including AVS machines with ES8336 and RT5663, Mediatek
MT7986, NXP i.MX93, RealTek RT1017 and StarFive JH7110
Others:
- 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
- Support for Cirrus CS35L56 and TI TAS2781 HD-audio sub-codecs

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;

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"

Pull sysctl updates from Luis Chamberlain:
"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.
- samples/hw_breakpoint minor fixes by Rong Tao, Arnd Bergmann and
Chen Jiahao"
