2025-03-15bpf: Allow pre-ordering for bpf cgroup progsYonghong Song
Currently for bpf progs in a cgroup hierarchy, the effective prog array is computed from bottom cgroup to upper cgroups (post-ordering). For example, the following cgroup hierarchy root cgroup: p1, p2 subcgroup: p3, p4 have BPF_F_ALLOW_MULTI for both cgroup levels. The effective cgroup array ordering looks like p3 p4 p1 p2 and at run time, progs will execute based on that order. But in some cases, it is desirable to have root prog executes earlier than children progs (pre-ordering). For example, - prog p1 intends to collect original pkt dest addresses. - prog p3 will modify original pkt dest addresses to a proxy address for security reason. The end result is that prog p1 gets proxy address which is not what it wants. Putting p1 to every child cgroup is not desirable either as it will duplicate itself in many child cgroups. And this is exactly a use case we are encountering in Meta. To fix this issue, let us introduce a flag BPF_F_PREORDER. If the flag is specified at attachment time, the prog has higher priority and the ordering with that flag will be from top to bottom (pre-ordering). For example, in the above example, root cgroup: p1, p2 subcgroup: p3, p4 Let us say p2 and p4 are marked with BPF_F_PREORDER. The final effective array ordering will be p2 p4 p3 p1 Suggested-by: Andrii Nakryiko <andrii@kernel.org> Acked-by: Andrii Nakryiko <andrii@kernel.org> Signed-off-by: Yonghong Song <yonghong.song@linux.dev> Link: https://lore.kernel.org/r/20250224230116.283071-1-yonghong.song@linux.dev Signed-off-by: Alexei Starovoitov <ast@kernel.org>

2025-03-15crypto: acomp - Add request chaining and virtual addressesHerbert Xu
This adds request chaining and virtual address support to the acomp interface. It is identical to the ahash interface, except that a new flag CRYPTO_ACOMP_REQ_NONDMA has been added to indicate that the virtual addresses are not suitable for DMA. This is because all existing and potential acomp users can provide memory that is suitable for DMA so there is no need for a fall-back copy path.

2025-03-14acpi/ghes, cxl/pci: Process CXL CPER Protocol ErrorsSmita Koralahalli
When PCIe AER is in FW-First, OS should process CXL Protocol errors from CPER records. Introduce support for handling and logging CXL Protocol errors. The defined trace events cxl_aer_uncorrectable_error and cxl_aer_correctable_error trace native CXL AER endpoint errors. Reuse them to trace FW-First Protocol errors. Since the CXL code is required to be called from process context and GHES is in interrupt context, use workqueues for processing. Similar to CXL CPER event handling, use kfifo to handle errors as it simplifies queue processing by providing lock free fifo operations. Add the ability for the CXL sub-system to register a workqueue to process CXL CPER protocol errors.

2025-03-14lockdep: Don't disable interrupts on RT in disable_irq_nosync_lockdep.*()Sebastian Andrzej Siewior
disable_irq_nosync_lockdep() disables interrupts with lockdep enabled to avoid false positive reports by lockdep that a certain lock has not been acquired with disabled interrupts. The user of this macros expects that a lock can be acquried without disabling interrupts because the IRQ line triggering the interrupt is disabled. This triggers a warning on PREEMPT_RT because after disable_irq_nosync_lockdep.*() the following spinlock_t now is acquired with disabled interrupts. On PREEMPT_RT there is no difference between spin_lock() and spin_lock_irq() so avoiding disabling interrupts in this case works for the two remaining callers as of today. Don't disable interrupts on PREEMPT_RT in disable_irq_nosync_lockdep.*().

2025-03-14cpu/SMT: Provide a default topology_is_primary_thread()Yicong Yang
Currently if architectures want to support HOTPLUG_SMT they need to provide a topology_is_primary_thread() telling the framework which thread in the SMT cannot offline. However arm64 doesn't have a restriction on which thread in the SMT cannot offline, a simplest choice is that just make 1st thread as the "primary" thread. So just make this as the default implementation in the framework and let architectures like x86 that have special primary thread to override this function (which they've already done). There's no need to provide a stub function if !CONFIG_SMP or !CONFIG_HOTPLUG_SMT. In such case the testing CPU is already the 1st CPU in the SMT so it's always the primary thread.

2025-03-14mfd: lp3943: Drop #include <linux/pwm.h> from headerUwe Kleine-König
The header doesn't make use of any symbols declared in <linux/pwm.h>. There are tree files that #include <mfd/lp3943.h>. Two of them (i.e. drivers/gpio/gpio-lp3943.c and drivers/mfd/lp3943.c) also don't use any and the third (drivers/pwm/pwm-lp3943.c) has an explicit include of <linux/pwm.h> itself. So drop the unused include. The intended side effect is that drivers/gpio/gpio-lp3943.c and drivers/mfd/lp3943.c stop importing the "PWM" module namespace.

Add support for STM32MP25 SoC. Use newly introduced compatible, to handle new features. Identification and hardware configuration registers allow to read the timer version and capabilities (counter width, number of channels...). So, rework the probe to avoid touching ARR register by simply read the counter width when available. This may avoid messing with a possibly running timer. Also add useful bit fields to stm32-timers header file.

The usual mixture of new drivers, support in existing drivers for new devices, a range of features and general subsystem cleanup. Two merges of immutable branches in here: * SPI offload support. Culmination of a long effort to bring the ability to offload triggered sequences of SPI operations to specific hardware, allow high datarate acquisition over an SPI bus (if you have the right hardware / FPGA firmware) * GPIO set-array-helper - enables code simplification. New device support ================== adi,ad3552r-hs: - Add support for AD3541r and AD3542r via newly supported FPGA HDL. adi,ad4030 - New driver supporting the AD4030, AD4630 AD4630-16, AD4640-24, AD4632-16, AD4632-24 1 and 2 channel high precision SPI ADCs. adi,ad4851 - New driver and backend support for the AD4851, AD4852, AD4853, AD4854, AD4855, AD4846, AD4857, AD4858 and AD4858I high speed multichannel simultaneous sampling ADCs. adi,ad7191 - New driver for this 24-bit ADC for precision bridge applications, adi,ad7380 - Add support for the adaq4381-4 which is a 14-bit version of the already supported adaq4380-1 adi,adis16550 - New driver using the ADIS library (which needed extensions) for this IMU. brcm,apds9160 - New driver for this proximity and ambient light sensor. dynaimage,al3000a - New driver for this illuminance sensor. mcube,mc3230 - Add support for the mc3510c accelerometer with a different scale to existing supported parts (some rework preceded this) nxp,imx93 - Add compatibles for imx94 and imx95 which are fully compatible with imx93. rockchip,saradc - Add support for the RK3528 ADC - Add support for the RK3562 ADC silab,si7210 - New driver to support this I2C Hall effect magnetic position sensor. ti,ads7138 - New driver supporting the ADS7128 and AD7138 I2C ADCs. Staging driver drop =================== adi,adis16240 - Drop this impact sensor. Interesting part but complex hence never left staging due to ABI challenges. No longer readily available so drop driver. New features ============ Documentation - A really nice overview document introduce ADC terminology and how it maps to IIO. core - New description for FAULT events, used in the ad7173. - filter_type ABI used in ad4130. buffer-dmaengine - Split DMA channel request from buffer allocation (for SPI offload) - Add a new _with_handle setup variant. (for SPI offload) adi,adf4371 - Add control of reference clock type and support for frequency doubling where appropriate. adi,ad4695 - Support SPI offload. - Support oversampling control. adi,ad5791 - Support SPI offload. adi,ad7124 - Add channel calibration support. adi,ad7380: - Alert support (threshold interrupts) - SPI offload support. adi,ad7606 - Support writing registers when using backend enabling software control of modes. adi,ad7944 - Support SPI offload. adi,ad9832 - Use devm_regulator_get_enable() to simplify code. adi,ad9834 - Use devm_regulator_get_enable() to simplify code. adi,adxl345 - Improve IRQ handling code. - Add debug access to registers. bosch,bmi270 - Add temperature channel support. - Add data ready trigger. google,cross_ec - Add trace events. mcube,mc3230 - Add mount matrix support - Add an OF match table. Cleanup and minor bug fixes =========================== Tree wide: - Stop using iio_device_claim_direct_scoped() and introduce sparse friendly iio_device_claim/release_direct() The conditional scoped cleanup has proved hard to deal with, requiring workarounds for various compiler issues and in is rather non-intuitive so abandon that experiment. One of the attractions of that approach was that it made it much harder to have unbalanced claim/release bugs so instead introduce a conditional-lock style boolean returning new pair of functions. These are inline in the header and have __acquire and __release calls allowing sparse to detect lack of balance. There are occasional false positives but so far those have reflected complex code paths that benefited from cleanup anyway. The first set of driver conversions are in this pull request, more to follow next cycle. Various related cleanup in drivers. Removal of the _scoped code is completed and the definition removed. - Use of str_enable_disable() and similar helpers. - Don't set regmap cache to REGCACHE_NONE as that's the default anyway. - Change some caches from RBTREE to MAPLE reflecting best practice. - Use the new gpiod_multi_set_value_cansleep() - Make sure to grab direct mode for some calibrations paths. - Avoid using memcmp on structures when checking for matching channel configs. Instead just match field by field. dt-bindings: - Fix up indentation inconsistencies. gts-helper: - Simplify building of available scale table. adi,ad-sigma-delta - Make sure to disable channel after calibration done. - Add error handling in configuring channel during calibration. adi,ad2s1201 - use a bitmap_write() rather than directly accessing underlying storage. adi,ad3552r-hs - Fix a wrong error message. - Make sure to use instruction mode for configuration. adi,ad4695 - Add a conversion to ensure exit from conversion mode. - Use custom regmap to handle required sclk rate change. - Fix an out of bounds array access - Simplify oversampling ratio handling. adi,ad4851 - Fix a sign bug. adi,ad5791 - Fix wrong exported number of storage bits. adi,ad7124 - Disable all channels at probe to avoid strange initial configurations. adi,ad7173 - Rework to allow static const struct ad_sigma_delta without need to make a copy. adi,ad7623 - Drop a BSD license tag that the authors consider unnecessary. adi,ad7768-1 - Fix channels sign description exposed to user space. - Set MOSI idle state to avoid accidental device reset. - Avoid some overkill locking. adi,axi-dac - Check if device interface is busy when enabling data stream. - Add control of bus mode. bosch,bmi270 - Move a struct definition to a c file as only used there. vishay,veml6030 - Enable regmap cache to reduce bus traffic. - Fix ABI bug around scale reporting. vishay,vem6075 - Check array bounds to harden against broken hardware.

2025-03-13zstd: Import upstream v1.5.7Nick Terrell
In addition to keeping the kernel's copy of zstd up to date, this update was requested by Intel to expose upstream's APIs that allow QAT to accelerate the LZ match finding stage of Zstd. This patch is imported from the upstream tag v1.5.7-kernel [0], which is signed with upstream's signing key EF8FE99528B52FFD [1]. It was imported from upstream using this command: export ZSTD=/path/to/repo/zstd/ export LINUX=/path/to/repo/linux/ cd "$ZSTD/contrib/linux-kernel" git checkout v1.5.7-kernel make import LINUX="$LINUX" This patch has been tested on x86-64, and has been boot tested with a zstd compressed kernel & initramfs on i386 and aarch64. I benchmarked the patch on x86-64 with gcc-14.2.1 on an Intel i9-9900K by measruing the performance of compressed filesystem reads and writes. Component, Level, Size delta, C. time delta, D. time delta Btrfs , 1, +0.00%, -6.1%, +1.4% Btrfs , 3, +0.00%, -9.8%, +3.0% Btrfs , 5, +0.00%, +1.7%, +1.4% Btrfs , 7, +0.00%, -1.9%, +2.7% Btrfs , 9, +0.00%, -3.4%, +3.7% Btrfs , 15, +0.00%, -0.3%, +3.6% SquashFS , 1, +0.00%, N/A, +1.9% The major changes that impact the kernel use cases for each version are: v1.5.7: https://github.com/facebook/zstd/releases/tag/v1.5.7 * Add zstd_compress_sequences_and_literals() for use by Intel's QAT driver to implement Zstd compression acceleration in the kernel. * Fix an underflow bug in 32-bit builds that can cause data corruption when processing more than 4GB of data with a single `ZSTD_CCtx` object, when an input crosses the 4GB boundry. I don't believe this impacts any current kernel use cases, because the `ZSTD_CCtx` is typically reconstructed between compressions. * Levels 1-4 see 5-10% compression speed improvements for inputs smaller than 128KB. v1.5.6: https://github.com/facebook/zstd/releases/tag/v1.5.6 * Improved compression ratio for the highest compression levels. I don't expect these see much use however, due to their slow speeds. v1.5.5: https://github.com/facebook/zstd/releases/tag/v1.5.5 * Fix a rare corruption bug that can trigger on levels 13 and above. * Improve compression speed of levels 5-11 on incompressible data. v1.5.4: https://github.com/facebook/zstd/releases/tag/v1.5.4 * Improve copmression speed of levels 5-11 on ARM. * Improve dictionary compression speed.
