Pull sound updates from Takashi Iwai:
"This looks like a relatively calm development cycle; there have been
only few changes in ALSA and ASoC core sides while we get lots of
device-specific fixes and updates as usual. Most of commits are about
ASoC, including Intel SOF/AVS and many device tree updates.
Below are some highlights:
Core:
- Improvement in memalloc helper for fallback allocations
- More cleanups of ASoC DAPM code
ASoC:
- Factoring out of mapping hw_params onto SoundWire configuration
- The ever ongoing overhauls of the Intel DSP code continue,
including support for loading libraries and probes with IPC4 on
SOF.
- Support for more sample formats on JZ4740
- Lots of device tree conversions and fixups
- Support for Allwinner D1, a range of AMD and Intel systems,
Mediatek systems with multiple DMICs, Nuvoton NAU8318, NXP
fsl_rpmsg and i.MX93, Qualcomm AudioReach Enable, MFC and SAL,
RealTek RT1318 and Rockchip RK3588
ALSA:
- Addition of PCM kselftest; still minimalistic but can be extended
in future
- Fixes for corner-case XRUNs with USB-audio implicit feedback mode
- Usual device-specific quirk updates for USB- and HD-audio
- FireWire DICE updates
This also contains a few cross-tree updates:
- Some OMAP board file updates for removal of relevant OMAP platforms
- A new I2C API update for I2C probe API adaption
- A DRM update for the further hdmi-codec updates"

Pull landlock updates from Mickaël Salaün:
"This adds file truncation support to Landlock, contributed by Günther
Noack. As described by Günther [1], the goal of these patches is to
work towards a more complete coverage of file system operations that
are restrictable with Landlock.
The known set of currently unsupported file system operations in
Landlock is described at [2]. Out of the operations listed there,
truncate is the only one that modifies file contents, so these patches
should make it possible to prevent the direct modification of file
contents with Landlock.
The new LANDLOCK_ACCESS_FS_TRUNCATE access right covers both the
truncate(2) and ftruncate(2) families of syscalls, as well as open(2)
with the O_TRUNC flag. This includes usages of creat() in the case
where existing regular files are overwritten.
Additionally, this introduces a new Landlock security blob associated
with opened files, to track the available Landlock access rights at
the time of opening the file. This is in line with Unix's general
approach of checking the read and write permissions during open(), and
associating this previously checked authorization with the opened
file. An ongoing patch documents this use case [3].
In order to treat truncate(2) and ftruncate(2) calls differently in an
LSM hook, we split apart the existing security_path_truncate hook into
security_path_truncate (for truncation by path) and
security_file_truncate (for truncation of previously opened files)"

Pull random number generator updates from Jason Donenfeld:
- Replace prandom_u32_max() and various open-coded variants of it,
there is now a new family of functions that uses fast rejection
sampling to choose properly uniformly random numbers within an
interval:
get_random_u32_below(ceil) - [0, ceil)
get_random_u32_above(floor) - (floor, U32_MAX]
get_random_u32_inclusive(floor, ceil) - [floor, ceil]
Coccinelle was used to convert all current users of
prandom_u32_max(), as well as many open-coded patterns, resulting in
improvements throughout the tree.
I'll have a "late" 6.1-rc1 pull for you that removes the now unused
prandom_u32_max() function, just in case any other trees add a new
use case of it that needs to converted. According to linux-next,
there may be two trivial cases of prandom_u32_max() reintroductions
that are fixable with a 's/.../.../'. So I'll have for you a final
conversion patch doing that alongside the removal patch during the
second week.
This is a treewide change that touches many files throughout.
- More consistent use of get_random_canary().
- Updates to comments, documentation, tests, headers, and
simplification in configuration.
- The arch_get_random*_early() abstraction was only used by arm64 and
wasn't entirely useful, so this has been replaced by code that works
in all relevant contexts.
- The kernel will use and manage random seeds in non-volatile EFI
variables, refreshing a variable with a fresh seed when the RNG is
initialized. The RNG GUID namespace is then hidden from efivarfs to
prevent accidental leakage.
These changes are split into random.c infrastructure code used in the
EFI subsystem, in this pull request, and related support inside of
EFISTUB, in Ard's EFI tree. These are co-dependent for full
functionality, but the order of merging doesn't matter.
- Part of the infrastructure added for the EFI support is also used for
an improvement to the way vsprintf initializes its siphash key,
replacing an sleep loop wart.
- The hardware RNG framework now always calls its correct random.c
input function, add_hwgenerator_randomness(), rather than sometimes
going through helpers better suited for other cases.
- The add_latent_entropy() function has long been called from the fork
handler, but is a no-op when the latent entropy gcc plugin isn't
used, which is fine for the purposes of latent entropy.
But it was missing out on the cycle counter that was also being mixed
in beside the latent entropy variable. So now, if the latent entropy
gcc plugin isn't enabled, add_latent_entropy() will expand to a call
to add_device_randomness(NULL, 0), which adds a cycle counter,
without the absent latent entropy variable.
- The RNG is now reseeded from a delayed worker, rather than on demand
when used. Always running from a worker allows it to make use of the
CPU RNG on platforms like S390x, whose instructions are too slow to
do so from interrupts. It also has the effect of adding in new inputs
more frequently with more regularity, amounting to a long term
transcript of random values. Plus, it helps a bit with the upcoming
vDSO implementation (which isn't yet ready for 6.2).
- The jitter entropy algorithm now tries to execute on many different
CPUs, round-robining, in hopes of hitting even more memory latencies
and other unpredictable effects. It also will mix in a cycle counter
when the entropy timer fires, in addition to being mixed in from the
main loop, to account more explicitly for fluctuations in that timer
firing. And the state it touches is now kept within the same cache
line, so that it's assured that the different execution contexts will
cause latencies.

Pull cxl updates from Dan Williams:
"Compute Express Link (CXL) updates for 6.2.
While it may seem backwards, the CXL update this time around includes
some focus on CXL 1.x enabling where the work to date had been with
CXL 2.0 (VH topologies) in mind.
First generation CXL can mostly be supported via BIOS, similar to DDR,
however it became clear there are use cases for OS native CXL error
handling and some CXL 3.0 endpoint features can be deployed on CXL 1.x
hosts (Restricted CXL Host (RCH) topologies). So, this update brings
RCH topologies into the Linux CXL device model.
In support of the ongoing CXL 2.0+ enabling two new core kernel
facilities are added.
One is the ability for the kernel to flag collisions between userspace
access to PCI configuration registers and kernel accesses. This is
brought on by the PCIe Data-Object-Exchange (DOE) facility, a hardware
mailbox over config-cycles.
The other is a cpu_cache_invalidate_memregion() API that maps to
wbinvd_on_all_cpus() on x86. To prevent abuse it is disabled in guest
VMs and architectures that do not support it yet. The CXL paths that
need it, dynamic memory region creation and security commands (erase /
unlock), are disabled when it is not present.
As for the CXL 2.0+ this cycle the subsystem gains support Persistent
Memory Security commands, error handling in response to PCIe AER
notifications, and support for the "XOR" host bridge interleave
algorithm.
Summary:
- Add the cpu_cache_invalidate_memregion() API for cache flushing in
response to physical memory reconfiguration, or memory-side data
invalidation from operations like secure erase or memory-device
unlock.
- Add a facility for the kernel to warn about collisions between
kernel and userspace access to PCI configuration registers
- Add support for Restricted CXL Host (RCH) topologies (formerly CXL
1.1)
- Add handling and reporting of CXL errors reported via the PCIe AER
mechanism
- Add support for CXL Persistent Memory Security commands
- Add support for the "XOR" algorithm for CXL host bridge interleave
- Rework / simplify CXL to NVDIMM interactions
- Miscellaneous cleanups and fixes"

Currently, kunit_parser.py is stripping all leading whitespace to make
parsing easier. But this means we can't accurately show kernel output
for failing tests or when the kernel crashes.
Embarassingly, this affects even KUnit's own output, e.g.
[13:40:46] Expected 2 + 1 == 2, but
[13:40:46] 2 + 1 == 3 (0x3)
[13:40:46] not ok 1 example_simple_test
[13:40:46] [FAILED] example_simple_test
After this change, here's what the output in context would look like
[13:40:46] =================== example (4 subtests) ===================
[13:40:46] # example_simple_test: initializing
[13:40:46] # example_simple_test: EXPECTATION FAILED at lib/kunit/kunit-example-test.c:29

[13:40:46] ===================== [FAILED] example =====================
This example shows one minor cosmetic defect this approach has.
The test counts lines prevent us from dedenting the suite-level output.
But at the same time, any form of non-KUnit output would do the same
unless it happened to be indented as well.

We print the "test log" on failure.
This is meant to be all the kernel output that happened during the test.
But we also include the special KTAP lines in it, which are often
redundant.
E.g. we include the "not ok" line in the log, right before we print
that the test case failed...

When --raw_output is set (to any value), we don't actually parse the
test results. So asking to print the test results as json doesn't make
sense.
We internally create a fake test with one passing subtest, so --json
would actually print out something misleading.
This patch:
* Rewords the flag descriptions so hopefully this is more obvious.
* Also updates --raw_output's description to note the default behavior
is to print out only "KUnit" results (actually any KTAP results)
* also renames and refactors some related logic for clarity (e.g.
test_result => test, it's a kunit_parser.Test object).
Notably, this patch does not make it an error to specify --json and
--raw_output together. This is an edge case, but I know of at least one
wrapper around kunit.py that always sets --json. You'd never be able to
use --raw_output with that wrapper.

Pull arm64 updates from Will Deacon:
"The highlights this time are support for dynamically enabling and
disabling Clang's Shadow Call Stack at boot and a long-awaited
optimisation to the way in which we handle the SVE register state on
system call entry to avoid taking unnecessary traps from userspace.
Summary:
ACPI:
- Enable FPDT support for boot-time profiling
- Fix CPU PMU probing to work better with PREEMPT_RT
- Update SMMUv3 MSI DeviceID parsing to latest IORT spec
- APMT support for probing Arm CoreSight PMU devices
CPU features:
- Advertise new SVE instructions (v2.1)
- Advertise range prefetch instruction
- Advertise CSSC ("Common Short Sequence Compression") scalar
instructions, adding things like min, max, abs, popcount
- Enable DIT (Data Independent Timing) when running in the kernel
- More conversion of system register fields over to the generated
header
CPU misfeatures:
- Workaround for Cortex-A715 erratum #2645198
Dynamic SCS:
- Support for dynamic shadow call stacks to allow switching at
runtime between Clang's SCS implementation and the CPU's pointer
authentication feature when it is supported (complete with scary
DWARF parser!)
Tracing and debug:
- Remove static ftrace in favour of, err, dynamic ftrace!
- Seperate 'struct ftrace_regs' from 'struct pt_regs' in core ftrace
and existing arch code
- Introduce and implement FTRACE_WITH_ARGS on arm64 to replace the
old FTRACE_WITH_REGS
- Extend 'crashkernel=' parameter with default value and fallback to
placement above 4G physical if initial (low) allocation fails
SVE:
- Optimisation to avoid disabling SVE unconditionally on syscall
entry and just zeroing the non-shared state on return instead
Exceptions:
- Rework of undefined instruction handling to avoid serialisation on
global lock (this includes emulation of user accesses to the ID
registers)
Perf and PMU:
- Support for TLP filters in Hisilicon's PCIe PMU device
- Support for the DDR PMU present in Amlogic Meson G12 SoCs
- Support for the terribly-named "CoreSight PMU" architecture from
Arm (and Nvidia's implementation of said architecture)
Misc:
- Tighten up our boot protocol for systems with memory above 52 bits
physical
- Const-ify static keys to satisty jump label asm constraints
- Trivial FFA driver cleanups in preparation for v1.1 support
- Export the kernel_neon_* APIs as GPL symbols

Pull slab updates from Vlastimil Babka:
- SLOB deprecation and SLUB_TINY
The SLOB allocator adds maintenance burden and stands in the way of
API improvements [1]. Deprecate it by renaming the config option (to
make users notice) to CONFIG_SLOB_DEPRECATED with updated help text.
SLUB should be used instead as SLAB will be the next on the removal
list.
Based on reports from a riscv k210 board with 8MB RAM, add a
CONFIG_SLUB_TINY option to minimize SLUB's memory usage at the
expense of scalability. This has resolved the k210 regression [2] so
in case there are no others (that wouldn't be resolvable by further
tweaks to SLUB_TINY) plan is to remove SLOB in a few cycles.
Existing defconfigs with CONFIG_SLOB are converted to
CONFIG_SLUB_TINY.

A series from Feng Tang that builds on the tracking or requested size
for kmalloc() allocations (for caches with debugging enabled) added

the rounded up one, in order to catch more subtle buffer overruns.
Includes new slub_kunit test.
- struct slab fields reordering to accomodate larger rcu_head
RCU folks would like to grow rcu_head with debugging options, which
breaks current struct slab layout's assumptions, so reorganize it to
make this possible.

These delays result in significant power savings on nearly idle
Android and ChromeOS systems. These savings range from a few percent
to more than ten percent.
This series also includes several commits that change call_rcu() to a
new call_rcu_hurry() function that avoids these delays in a few
cases, for example, where timely wakeups are required. Several of
these are outside of RCU and thus have acks and reviews from the
relevant maintainers.

This is the (user-space) runtime verification tool, named rv.
This tool aims to be the interface for in-kernel rv monitors, as
well as the home for monitors in user-space (online asynchronous),
and in *eBPF.
The tool receives a command as the first argument, the current
commands are:
list - list all available monitors
mon - run a given monitor
Each monitor is an independent piece of software inside the
tool and can have their own arguments.
There is no monitor implemented in this patch, it only
adds the basic structure of the tool, based on rtla.
# rv --help
rv version 6.1.0-rc4: help
usage: rv command [-h] [command_options]
-h/--help: print this menu
command: run one of the following command:
list: list all available monitors
mon: run a monitor
[command options]: each command has its own set of options
run rv command -h for further information
*dot2bpf is the next patch set, depends on this, doing cleanups.

rtla_usage(), osnoise_usage() and timerlat_usage() all exit with an
error status.
However when these are called from help, they should exit with a
non-error status.
Fix this by passing the exit status to the functions.
Note, although we remove the subsequent call to exit after calling
usage, we leave it in at the end of a function to suppress the compiler
warning "control reaches end of a non-void function".

grub2 has submenus where to use grub-reboot, it requires:
grub-reboot X>Y
where X is the main index and Y is the submenu. Thus if you have:
menuentry 'Debian GNU/Linux' --class debian --class gnu-linux ...
[...]
}
submenu 'Advanced options for Debian GNU/Linux' $menuentry_id_option ...
menuentry 'Debian GNU/Linux, with Linux 6.0.0-4-amd64' --class debian --class gnu-linux ...
[...]
}
menuentry 'Debian GNU/Linux, with Linux 6.0.0-4-amd64 (recovery mode)' --class debian --class gnu-linux ...
[...]
}
menuentry 'Debian GNU/Linux, with Linux test' --class debian --class gnu-linux ...
[...]
}
And wanted to boot to the "Linux test" kernel, you need to run:
# grub-reboot 1>2
As 1 is the second top menu (the submenu) and 2 is the third of the sub
menu entries.
Have the grub.cfg parsing for grub2 handle such cases.

After a full run of a make_min_config test, I noticed there were a lot of
CONFIGs still enabled that really should not be. Looking at them, I
noticed they were all defined as "default y". The issue is that the test
simple removes the config and re-runs make oldconfig, which enables it
again because it is set to default 'y'. Instead, explicitly disable the
config with writing "# CONFIG_FOO is not set" to the file to keep it from
being set again.
With this change, one of my box's minconfigs went from 768 configs set,
down to 521 configs set.

Cited commit added the table ID to the FIB info structure, but did not
properly initialize it when table ID 0 is used. This can lead to a route
in the default VRF with a preferred source address not being flushed
when the address is deleted.
Consider the following example:
# ip address add dev dummy1 192.0.2.1/28
# ip address add dev dummy1 192.0.2.17/28
# ip route add 198.51.100.0/24 via 192.0.2.2 src 192.0.2.17 metric 100
# ip route add table 0 198.51.100.0/24 via 192.0.2.2 src 192.0.2.17 metric 200
# ip route show 198.51.100.0/24
198.51.100.0/24 via 192.0.2.2 dev dummy1 src 192.0.2.17 metric 100
198.51.100.0/24 via 192.0.2.2 dev dummy1 src 192.0.2.17 metric 200
Both routes are installed in the default VRF, but they are using two
different FIB info structures. One with a metric of 100 and table ID of
254 (main) and one with a metric of 200 and table ID of 0. Therefore,
when the preferred source address is deleted from the default VRF,
the second route is not flushed:
# ip address del dev dummy1 192.0.2.17/28
# ip route show 198.51.100.0/24
198.51.100.0/24 via 192.0.2.2 dev dummy1 src 192.0.2.17 metric 200
Fix by storing a table ID of 254 instead of 0 in the route configuration
structure.
Add a test case that fails before the fix:

Cited commit added the table ID to the FIB info structure, but did not
prevent structures with different table IDs from being consolidated.
This can lead to routes being flushed from a VRF when an address is

info. This is already done for FIB info structures backed by a nexthop

ASoC: Updates for v6.2
This is a fairly sedate release for the core code, but there's been a
lot of driver work especially around the x86 platforms and device tree
updates:
- More cleanups of the DAPM code from Morimoto-san.
- Factoring out of mapping hw_params onto SoundWire configuration by
Charles Keepax.
- The ever ongoing overhauls of the Intel DSP code continue, including
support for loading libraries and probes with IPC4 on SOF.
- Support for more sample formats on JZ4740.
- Lots of device tree conversions and fixups.
- Support for Allwinner D1, a range of AMD and Intel systems, Mediatek
systems with multiple DMICs, Nuvoton NAU8318, NXP fsl_rpmsg and
i.MX93, Qualcomm AudioReach Enable, MFC and SAL, RealTek RT1318 and
Rockchip RK3588
There's more cross tree updates than usual, though all fairly minor:
- Some OMAP board file updates that were depedencies for removing their
providers in ASoC, as part of a wider effort removing the support for
the relevant OMAP platforms.
- A new I2C API required for updates to the new I2C probe API.
- A DRM update making use of a new API for fixing the capabilities
advertised via hdmi-codec.
Since this is being sent early I might send some more stuff if you've
not yet sent your pull request and there's more come in.
