crypto/arm64: sm4/xts - Merge ksimd scopes to reduce stack bloat
Merge the two ksimd scopes in the implementation of SM4-XTS to prevent stack bloat in cases where the compiler fails to combine the stack slots for the kernel mode FP/SIMD buffers. Signed-off-by: Ard Biesheuvel <ardb@kernel.org> Tested-by: Arnd Bergmann <arnd@arndb.de> Link: https://lore.kernel.org/r/20251203163803.157541-6-ardb@kernel.org Signed-off-by: Eric Biggers <ebiggers@kernel.org> |

crypto/arm64: aes/xts - Use single ksimd scope to reduce stack bloat
The ciphertext stealing logic in the AES-XTS implementation creates a
separate ksimd scope to call into the FP/SIMD core routines, and in some
cases (CONFIG_KASAN_STACK is one, but there might be others), the 528
byte kernel mode FP/SIMD buffer that is allocated inside this scope is
not shared with the preceding ksimd scope, resulting in unnecessary
stack bloat.
Considering that
a) the XTS ciphertext stealing logic is never called for block
encryption use cases, and XTS is rarely used for anything else,
b) in the vast majority of cases, the entire input block is processed
during the first iteration of the loop,
we can combine both ksimd scopes into a single one with no practical
impact on how often/how long FP/SIMD is en/disabled, allowing us to
reuse the same stack slot for both FP/SIMD routine calls.

lib/crypto: blake2s: Replace manual unrolling with unrolled_full
As we're doing in the BLAKE2b code, use unrolled_full to make the compiler handle the loop unrolling. This simplifies the code slightly. The generated object code is nearly the same with both gcc and clang.

lib/crypto: blake2b: Roll up BLAKE2b round loop on 32-bit
BLAKE2b has a state of 16 64-bit words. Add the message data in and
there are 32 64-bit words. With the current code where all the rounds
are unrolled to enable constant-folding of the blake2b_sigma values,
this results in a very large code size on 32-bit kernels, including a
recurring issue where gcc uses a large amount of stack.
There's just not much benefit to this unrolling when the code is already
so large. Let's roll up the rounds when !CONFIG_64BIT.
To avoid having to duplicate the code, just write the code once using a
loop, and conditionally use 'unrolled_full' from <linux/unroll.h>.
Then, fold the now-unneeded ROUND() macro into the loop. Finally, also
remove the now-unneeded override of the stack frame size warning.
Code size improvements for blake2b_compress_generic():
Size before (bytes) Size after (bytes)
------------------- ------------------
i386, gcc 27584 3632
i386, clang 18208 3248
arm32, gcc 19912 2860
arm32, clang 21336 3344
Running the BLAKE2b benchmark on a !CONFIG_64BIT kernel on an x86_64
processor shows a 16384B throughput change of 351 => 340 MB/s (gcc) or
442 MB/s => 375 MB/s (clang). So clearly not much of a slowdown either.
But also that microbenchmark also effectively disregards cache usage,
which is important in practice and is far better in the smaller code.
Note: If we rolled up the loop on x86_64 too, the change would be
7024 bytes => 1584 bytes and 1960 MB/s => 1396 MB/s (gcc), or
6848 bytes => 1696 bytes and 1920 MB/s => 1263 MB/s (clang).
Maybe still worth it, though not quite as clearly beneficial.

lib/crypto: riscv: Depend on RISCV_EFFICIENT_VECTOR_UNALIGNED_ACCESS
Replace the RISCV_ISA_V dependency of the RISC-V crypto code with RISCV_EFFICIENT_VECTOR_UNALIGNED_ACCESS, which implies RISCV_ISA_V as well as vector unaligned accesses being efficient. This is necessary because this code assumes that vector unaligned accesses are supported and are efficient. (It does so to avoid having to use lots of extra vsetvli instructions to switch the element width back and forth between 8 and either 32 or 64.) This was omitted from the code originally just because the RISC-V kernel support for detecting this feature didn't exist yet. Support has now been added, but it's fragmented into per-CPU runtime detection, a command-line parameter, and a kconfig option. The kconfig option is the only reasonable way to do it, though, so let's just rely on that. Fixes: |

lib/crypto: riscv/chacha: Avoid s0/fp register
In chacha_zvkb, avoid using the s0 register, which is the frame pointer,
by reallocating KEY0 to t5. This makes stack traces available if e.g. a
crash happens in chacha_zvkb.
No frame pointer maintenance is otherwise required since this is a leaf
function.

lockref: add a __cond_lock annotation for lockref_put_or_lock
Add a cond_lock annotation for lockref_put_or_lock to make sparse happy with using it. Note that for this the return value has to be double-inverted as the return value convention of lockref_put_or_lock is inverted compared to _trylock conventions expected by __cond_lock, as lockref_put_or_lock returns true when it did not need to take the lock.

compiler_types.h: add "auto" as a macro for "__auto_type"
"auto" was defined as a keyword back in the K&R days, but as a storage type specifier. No one ever used it, since it was and is the default storage type for local variables. C++11 recycled the keyword to allow a type to be declared based on the type of an initializer. This was finally adopted into standard C in C23. gcc and clang provide the "__auto_type" alias keyword as an extension for pre-C23, however, there is no reason to pollute the bulk of the source base with this temporary keyword; instead define "auto" as a macro unless the compiler is running in C23+ mode. This macro is added in <linux/compiler_types.h> because that header is included in some of the tools headers, wheres <linux/compiler.h> is not as it has a bunch of very kernel-specific things in it. [ Cc: stable to reduce potential backporting burden. ] Signed-off-by: H. Peter Anvin (Intel) <hpa@zytor.com> Acked-by: Miguel Ojeda <ojeda@kernel.org> Cc: <stable@kernel.org> |

Pin control changes for the v6.19 kernel cycle:
Core changes:
- Handle per-direction skew control in the generic pin config.
- Drop the pointless subsystem boilerplate banner message during
boot. Less noise in the console. It's available as debug message
if someone really want it.
New drivers:
- Samsung Exynos 8890 SoC support.
- Samsung Exynos derived Axis Communications ARTPEC-9 SoC support.
These guys literally live next door to me, ARTPEC spells out
"Axis Real-Time Picture Encoding Chip" and is tailored for camera
image streams and is something they have evolved for a quarter of
a century.
- Mediatek MT6878 SoC support.
- Qualcomm Glymur PMIC support (mostly just compatible strings).
- Qualcomm Kaanapali SoC TLMM support.
- Microchip pic64gx "gpio2" SoC support.
- Microchip Polarfire "iomux0" SoC support.
- CIX Semiconductors SKY1 SoC support.
- Rockchip RK3506 SoC support.
- Airhoa AN7583 chip support.
Improvements:
- Improvements for ST Microelectronics STM32 handling of skew
settings so input and output can have different skew settings.
- A whole bunch of device tree binding cleanups: Marvell Armada and
Berlin, Actions Semiconductor S700 and S900, Broadcom Northstar 2
(NS2), Bitmain BM1880 and Spreadtrum SC9860 are moved over to schema.

hwmon: (emc2305) fix device node refcount leak in error path
The for_each_child_of_node() macro automatically manages device node reference counts during normal iteration. However, when breaking out of the loop early with return, the current iteration's node is not automatically released, leading to a reference count leak. Fix this by adding of_node_put(child) before returning from the loop when emc2305_set_single_tz() fails. This issue could lead to memory leaks over multiple probe cycles.

hwmon: (w83791d) Convert macros to functions to avoid TOCTOU
The macro FAN_FROM_REG evaluates its arguments multiple times. When used
in lockless contexts involving shared driver data, this leads to
Time-of-Check to Time-of-Use (TOCTOU) race conditions, potentially
causing divide-by-zero errors.
Convert the macro to a static function. This guarantees that arguments
are evaluated only once (pass-by-value), preventing the race
conditions.
Additionally, in store_fan_div, move the calculation of the minimum
limit inside the update lock. This ensures that the read-modify-write
sequence operates on consistent data.
Adhere to the principle of minimal changes by only converting macros
that evaluate arguments multiple times and are used in lockless
contexts.

[GIT PULL] perf tools changes for v6.19
Perf event/metric description
-----------------------------
Unify all event and metric descriptions in JSON format.
Now event parsing and handling is greatly simplified by that.
From users point of view, perf list will provide richer
information about hardware events like the following.
$ perf list hw
List of pre-defined events (to be used in -e or -M):
legacy hardware:
branch-instructions
[Retired branch instructions [This event is an alias of branches]. Unit: cpu]
branch-misses
[Mispredicted branch instructions. Unit: cpu]
branches
[Retired branch instructions [This event is an alias of branch-instructions]. Unit: cpu]
bus-cycles
[Bus cycles,which can be different from total cycles. Unit: cpu]
cache-misses
[Cache misses. Usually this indicates Last Level Cache misses; this is intended to be used in conjunction with the
PERF_COUNT_HW_CACHE_REFERENCES event to calculate cache miss rates. Unit: cpu]
cache-references
[Cache accesses. Usually this indicates Last Level Cache accesses but this may vary depending on your CPU. This may include
prefetches and coherency messages; again this depends on the design of your CPU. Unit: cpu]

[Total cycles. Be wary of what happens during CPU frequency scaling [This event is an alias of cycles]. Unit: cpu]

[Total cycles. Be wary of what happens during CPU frequency scaling [This event is an alias of cpu-cycles]. Unit: cpu]
instructions
[Retired instructions. Be careful,these can be affected by various issues,most notably hardware interrupt counts. Unit: cpu]
ref-cycles
[Total cycles; not affected by CPU frequency scaling. Unit: cpu]
But most notable changes would be in the perf stat. On the right side,
the default metrics are better named and aligned. :)

Deferred unwinding support
--------------------------
With the kernel support [1], perf can use deferred callchains for
userspace stack trace with frame pointers like below:
$ perf record --call-graph fp,defer ...
This will be transparent to users when it comes to other commands like
perf report and perf script. They will merge the deferred callchains to
the previous samples as if they were collected together.
[1] https://git.kernel.org/torvalds/c/c69993ecdd4dfde2b7da08b022052a33b203da07
ARM SPE updates
---------------
* Extensive enhancements to support various kinds of memory operations
including GCS, MTE allocation tags, memcpy/memset, register access,
and SIMD operations.
* Add inverted data source filter (inv_data_src_filter) support to
exclude certain data sources.
* Improve documentation.
Vendor event updates
--------------------
* Intel: Updated event files for Sierra Forest, Panther Lake, Meteor Lake,
Lunar Lake, Granite Rapids, and others.
* Arm64: Added metrics for i.MX94 DDR PMU and Cortex-A720AE definitions.
* RISC-V: Added JSON support for T-HEAD C920V2.
Misc
----
* Improve pointer tracking in data type profiling. It'd give better
output when the variable is using container_of() to convert type.
* Annotation support for perf c2c report in TUI. Press 'a' key to
enter annotation view from cacheline browser window. This will show
which instruction is causing the cacheline contention.
* Lots of fixes and test coverage improvements!

Deferred unwinding support:
With the kernel support (commit c69993ecdd4d: "perf: Support deferred
user unwind"), perf can use deferred callchains for userspace stack
trace with frame pointers like below:
$ perf record --call-graph fp,defer ...
This will be transparent to users when it comes to other commands like
perf report and perf script. They will merge the deferred callchains
to the previous samples as if they were collected together.
ARM SPE updates
- Extensive enhancements to support various kinds of memory
operations including GCS, MTE allocation tags, memcpy/memset,
register access, and SIMD operations.
- Add inverted data source filter (inv_data_src_filter) support to
exclude certain data sources.
- Improve documentation.
Vendor event updates:
- Intel: Updated event files for Sierra Forest, Panther Lake, Meteor
Lake, Lunar Lake, Granite Rapids, and others.
- Arm64: Added metrics for i.MX94 DDR PMU and Cortex-A720AE
definitions.
- RISC-V: Added JSON support for T-HEAD C920V2.
Misc:
- Improve pointer tracking in data type profiling. It'd give better
output when the variable is using container_of() to convert type.
- Annotation support for perf c2c report in TUI. Press 'a' key to
enter annotation view from cacheline browser window. This will show
which instruction is causing the cacheline contention.
- Lots of fixes and test coverage improvements!"

Staging driver updates for 6.19-rc1

TTY/Serial changes for 6.19-rc1
Here is the big set of tty/serial driver changes for 6.19-rc1. Nothing
major at all, just small constant churn to make the tty layer "cleaner"
as well as serial driver updates and even a new test added! Included in
here are:

- tty tiocsti test added to hopefully ensure we don't regress in this

- sc16is7xx driver updates
- imx serial driver updates
- 8250 driver updates
- new hardware device ids added
- other minor serial/tty driver cleanups and tweaks
All of these have been in linux-next for a while with no reported issues
other than a merge-conflict that you will have when you merge into your

of the merge).

Significant patch series in this pull request:
- The 6 patch series "panic: sys_info: Refactor and fix a potential
issue" from Andy Shevchenko fixes a build issue and does some cleanup in
ib/sys_info.c.
- The 9 patch series "Implement mul_u64_u64_div_u64_roundup()" from
David Laight enhances the 64-bit math code on behalf of a PWM driver and
beefs up the test module for these library functions.
- The 2 patch series "scripts/gdb/symbols: make BPF debug info available
to GDB" from Ilya Leoshkevich makes BPF symbol names, sizes, and line
numbers available to the GDB debugger.
- The 4 patch series "Enable hung_task and lockup cases to dump system
info on demand" from Feng Tang adds a sysctl which can be used to cause
additional info dumping when the hung-task and lockup detectors fire.
- The 6 patch series "lib/base64: add generic encoder/decoder, migrate
users" from Kuan-Wei Chiu adds a general base64 encoder/decoder to lib/
and migrates several users away from their private implementations.
- The 2 patch series "rbree: inline rb_first() and rb_last()" from Eric
Dumazet makes TCP a little faster.
- The 9 patch series "liveupdate: Rework KHO for in-kernel users" from
Pasha Tatashin reworks the KEXEC Handover interfaces in preparation for
Live Update Orchestrator (LUO), and possibly for other future clients.
- The 13 patch series "kho: simplify state machine and enable dynamic
updates" from Pasha Tatashin increases the flexibility of KEXEC
Handover. Also preparation for LUO.
- The 18 patch series "Live Update Orchestrator" from Pasha Tatashin is
a major new feature targeted at cloud environments. Quoting the [0/N]:
This series introduces the Live Update Orchestrator, a kernel subsystem
designed to facilitate live kernel updates using a kexec-based reboot.
This capability is critical for cloud environments, allowing hypervisors
to be updated with minimal downtime for running virtual machines. LUO
achieves this by preserving the state of selected resources, such as
memory, devices and their dependencies, across the kernel transition.
As a key feature, this series includes support for preserving memfd file
descriptors, which allows critical in-memory data, such as guest RAM or
any other large memory region, to be maintained in RAM across the kexec
reboot.
Mike Rappaport merits a mention here, for his extensive review and
testing work.
- The 3 patch series "kexec: reorganize kexec and kdump sysfs" from
Sourabh Jain moves the kexec and kdump sysfs entries from /sys/kernel/
to /sys/kernel/kexec/ and adds back-compatibility symlinks which can
hopefully be removed one day.
- The 2 patch series "kho: fixes for vmalloc restoration" from Mike
Rapoport fixes a BUG which was being hit during KHO restoration of
vmalloc() regions.

the hung-task and lockup detectors fire
- "lib/base64: add generic encoder/decoder, migrate users" (Kuan-Wei Chiu)
adds a general base64 encoder/decoder to lib/ and migrates several
users away from their private implementations
- "rbree: inline rb_first() and rb_last()" (Eric Dumazet)
makes TCP a little faster
- "liveupdate: Rework KHO for in-kernel users" (Pasha Tatashin)
reworks the KEXEC Handover interfaces in preparation for Live Update
Orchestrator (LUO), and possibly for other future clients
- "kho: simplify state machine and enable dynamic updates" (Pasha Tatashin)
increases the flexibility of KEXEC Handover. Also preparation for LUO
- "Live Update Orchestrator" (Pasha Tatashin)
is a major new feature targeted at cloud environments. Quoting the
cover letter:
This series introduces the Live Update Orchestrator, a kernel
subsystem designed to facilitate live kernel updates using a
kexec-based reboot. This capability is critical for cloud
environments, allowing hypervisors to be updated with minimal
downtime for running virtual machines. LUO achieves this by
preserving the state of selected resources, such as memory,
devices and their dependencies, across the kernel transition.
As a key feature, this series includes support for preserving
memfd file descriptors, which allows critical in-memory data, such
as guest RAM or any other large memory region, to be maintained in
RAM across the kexec reboot.
Mike Rappaport merits a mention here, for his extensive review and
testing work.
- "kexec: reorganize kexec and kdump sysfs" (Sourabh Jain)
moves the kexec and kdump sysfs entries from /sys/kernel/ to
/sys/kernel/kexec/ and adds back-compatibility symlinks which can
hopefully be removed one day
- "kho: fixes for vmalloc restoration" (Mike Rapoport)
fixes a BUG which was being hit during KHO restoration of vmalloc()
regions

tracing fixes for v6.19:
- Fix accounting of stop_count in file release On opening the trace file, if "pause-on-trace" option is set, it will increment the stop_count. On file release, it checks if stop_count is set, and if so it decrements it. Since this code was originally written, the stop_count can be incremented by other use cases. This makes just checking the stop_count not enough to know if it should be decremented. Add a new iterator flag called "PAUSE" and have it set if the open disables tracing and only decrement the stop_count if that flag is set on close. - Remove length field in trace_seq_printf() of print_synth_event() When printing the synthetic event that has a static length array field, the vsprintf() of the trace_seq_printf() triggered a "(efault)" in the output. That's because the print_fmt replaced the "%.*s" with "%s" causing the arguments to be off. - Fix a bunch of typos -----BEGIN PGP SIGNATURE----- iIoEABYKADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCaTRsYBQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qrYpAQC3Qc5QMOlPjqGHXls/4IR4SBEAvsUi VZx3PdknfYCe3AD9HoYGOtrDDhSJ1tQbsWP5ud2jatHwL0zGAl3legNp7ww= =jlNP -----END PGP SIGNATURE----- Merge tag 'trace-v6.19-2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing fixes from Steven Rostedt: - Fix accounting of stop_count in file release On opening the trace file, if "pause-on-trace" option is set, it will increment the stop_count.
