11 daysconfigfs-tsm-report: tdx_guest: Increase Quote buffer size to 128KBKuppuswamy Sathyanarayanan1-0/+4
Intel platforms are transitioning from traditional SGX-based attestation toward DICE-based attestation as part of a broader move toward open and standardized attestation models. DICE enables layered and extensible attestation, where evidence is accumulated across multiple boot stages. With SGX-based attestation, Quote sizes are typically under 8KB, as the payload consists primarily of Quote data and a small certificate bundle. Existing TDX guest code sizes the Quote buffer accordingly. DICE-based attestation produces significantly larger Quotes due to the inclusion of evidence (certificate chains) from multiple boot layers. The cumulative Quote size can reach approximately 100KB. Increase GET_QUOTE_BUF_SIZE to 128KB to ensure sufficient buffer capacity for DICE-based Quote payloads.

The configfs-tsm-report interface can fail with -EFBIG when the attestation report generated by a TSM provider exceeds internal maximums (TSM_REPORT_OUTBLOB_MAX). However, this error condition and its handling are not currently documented in the ABI. Userspace tools need to understand how to interpret various error conditions when reading attestation reports. Document that reads fail with -EFBIG when reports exceed size limits, with guidance on how to resolve them.

2026-02-03erofs: separate plain and compressed filesystems formallyGao Xiang1-3/+3
The EROFS on-disk format uses a tiny, plain metadata design that prioritizes performance and minimizes complex inconsistencies against common writable disk filesystems (almost all serious metadata inconsistency cannot happen in well-designed immutable filesystems like EROFS). EROFS deliberately avoids artificial design flaws to eliminate serious security risks from untrusted remote sources by design, although human-made implementation bugs can still happen sometimes. Currently, there is no strict check to prevent compressed inodes, especially LZ4-compressed inodes, from being read in plain filesystems. Starting with erofs-utils 1.0 and Linux 5.3, LZ4_0PADDING sb feature is automatically enabled for LZ4-compressed EROFS images to support in-place decompression. Furthermore, since Linux 5.4 LTS is no longer supported, we no longer need to handle ancient LZ4-compressed EROFS images generated by erofs-utils prior to 1.0. To formally distinguish different filesystem types for improved security: - Use the presence of LZ4_0PADDING or a non-zero `dsb->u1.lz4_max_distance` as a marker for compressed filesystems containing LZ4-compressed inodes only; - For other algorithms, use `dsb->u1.available_compr_algs` bitmap. Note: LZ4_0PADDING has been supported since Linux 5.4 (the first formal kernel version), so exposing it via sysfs is no longer necessary and is now deprecated (but remain it for five more years until 2031): `dsb->u1` has been strictly non-zero for all EROFS images containing compressed inodes starting with erofs-utils v1.3 and it is actually a much better marker for compressed filesystems.

ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/jic23/iio into char-misc-next Jonathan writes: IIO: New device support, features and cleanup for the 6.20/7.0 cycle. Slightly messier than normal unfortunately due to some conflicts and build config bugs related to I3C drivers. One last minute Kconfig fix right at the top after a linux-next report. I've simplified the Kconfig and made it match other instances in the kernel so that should be safe enough despite short soak time in front of build bots. Merge of an immutable branch from I3C to get some stubs that were missing and caused build issues with dual I2C / I3C drivers. This also brought in a drop of some deprecated interfaces so there is also one patch to update a new driver to not use those. We are having another go at using cleanup.h magic with the IIO mode claim functions after backing out last try at this. This time we have wrappers around the new ACQUIRE() and ACQUIRE_ERR() macros. Having been burnt once, we will be taking it a bit more slowly this time wrt to wide adoption of these! Thanks in particular to Kurt for taking on this core IIO work. New Device Support ================== adi,ad18113 - New driver to support the AD18113 amplifier - an interesting device due to the external bypass paths where we need to describe what gain those paths have in DT. Longer term it will be interesting to see if this simplistic description is enough for real deployments. adi,ad4062 - New driver for the AD4060 and AD4052 SAR ADCs including trigger, event and GPIO controller support. Follow up patch replaced use of some deprecated I3C interfaces prior to the I3C immutable branch merge as that includes dropping them. adi,ad4134 - New driver for the AD4134 24bit 4 channel simultaneous sampling ADC. adi,ad7768-1, - Add support for the ADAQ767-1, ADAQ7768-1 and ADAQ7769-1 ADCs after some rework to enable the driver to support multiple device types. adi,ad9467 - Add support for the similar ad9211 ADC to this existing driver. - Make the selection of 2s comp mode explicit for normal operation and switch to offset binary when entering calibration mode. honeywell,abp2 - New driver to support this huge family (100+) of board mount pressure and temperature sensors. maxim,max22007 - New drier for this 4 channel DAC. memsic,mmc5633 - New driver for this I2C/I3C magnetometer. Follow on patches fixed up issues related to single driver supporting both bus types. microchip,mcp747feb02 - New driver for the Microchip MCP47F(E/V)B(0/1/2)1, MCP47F(E/V)B(0/1/2)2, MCP47F(E/V)B(0/1/2)4 and MCP47F(E/V)B(0/1/2)8 buffered voltage output DACs. nxp,sar-adc - New driver support ADCs found on s32g2 and s32g3 platforms. ti,ads1018 - New drier for the ADS1018 and ADS1118 SPI ADCs. ti,ads131m02 - New driver supporting ADS131M(02/03/04/06/08)24-bit simultaneous sampling ADCs. Features ======== iio-core - New IIO_DEV_ACQUIRE_DIRECT_MODE() / IIO_DEV_ACQUIRE_FAILED() + equivalents for the much rarer case where the mode needs pinning whether or not it is in direct mode. These use the ACQUIRE() / ACQUIRE_ERR() infrastructure underneath to provide both simple checks on whether we got the requested mode and to provide scope based release. Applied in a few initial drivers. adi,ad9467 - Support calibbias control adi,adf4377 - Add support to act as a clock provider. adi,adxl380 - Support low power 1KHz sampling frequency mode. Required rework of how events and filters were configured, plus applying of constraints when in this mode. rf-digital,rfd77402 - Add interrupt support as alternative to polling for completion. st,lsm6dsx - Tap event detection (after considerable driver rework) Cleanup and Minor Fixes ======================= More minor cleanup such as typos, white space etc not called out except where they were applied to a lot of drivers. Various drivers. - Use of dev_err_probe() to cleanup error handling. - Introduce local struct device and struct device_node variables to reduce duplication of getting them from containing structs. - Ensure uses of iio_trigger_generic_data_rdy_poll() set IRQF_NO_THREAD as that function calls non threaded child interrupt handlers. - Replace IRQF_ONESHOT in not thread interrupt handlers with IRQF_NO_THREAD to ensure they run as intended. Drop one unnecessary case. iio-sw-device/trigger. - Constify configs_group_operations structures. iio-buffer-dma / buffer-dma-engine - Use lockdep_assert_held() to replace WARN_ON() to check lock is correctly held. - Make use of cleanup.h magic to simplify various code paths. - Make iio_dma_buffer_init() return void rather than always success. adi,ad7766 - Replace custom interrupt handler with iio_trigger_generic_data_rdy_poll() adi,ad9832 - Drop legacy platform_data support. adi,ade9000 - Add a maintainer entry. adi,adt7316 - Move to EXPORT_GPL_SIMPLE_DEV_PM_OPS() and pm_sleep_ptr() so the compiler can cleanly drop unused pm structures and callbacks. adi,adxl345 - Relax build constraint vs the driver that is in input so both may be built as modules and selection made at runtime. adi,adxl380 - Make sure we don't read tail entries in the hardware fifo if a partial new scan has been written. - Move to a single larger regmap_noinc_read() to read the hardware fifo. aspeed,ast2600 - Add missing interrupts property to DT binding. bosch,bmi270_i2c - Add missing MODULE_DEVICE_TABLE() macros so auto probing of modules can work. bosch,smi330 - Drop duplicate assignment of IIO_TYPE in smi330_read_avail() - Use new common field_get() and field_prep() helpers to replace local version. honeywell,mprls0025pa Fixes delayed to merge window as late in cycle and we didn't want to delay the rest of the series. - Allow Kconfig selection of specific bus sub-drivers rather than tying that to the buses themselves being supported. - Zero spi_transfer structure to avoid chance of unintentionally set fields effecting transfer. - Fix a potential timing violation wrt to the chip select to first clock edge timing. - As recent driver, take risk inherent in dropping interrupt direction from driver as that should be set by firmware. - Fix wrong reported number of data bits for channel. - Fix a pressure channel calculation bug. - Rework to allow embedding the tx buffer in the iio_priv() structure rather than requiring separate allocation. - Move the buffer clearing to the shared core bringing it into affect for SPI as well as I2C. - Stricter checks for status byte. - Greatly simplify the measurement sequence. - Add a copyright entry to reflect Petre's continued work on this driver. intersil,isl29018 - Switch from spritnf to sysfs_emit_at() to make it clear overflow can't occur. invensense,icm42600 - Allow sysfs access to temperature when buffered capture in use as it does not impact other sensor data paths. invensense,itg3200 - Check unused return value in read_raw() callback. men,z188 - Drop now duplicated module alias. rf-digital,rfd77402 - Add DT binding doc and explicit of_device_id table. - Poll for timeout with times as on datasheet, then replace opencoded version with read_poll_timeout(). sensiron,scd4x - Add missing timestamp channel.

If userspace thread has held f2fs rw semaphore, due to its low priority, it could be runnable or preempted state for long time, during the time, it will block high priority thread which is trying to grab the same rw semaphore, e.g. cp_rwsem, io_rwsem... To fix such issue, let's detect thread's priority when it tries to grab f2fs_rwsem lock, if the priority is lower than a priority threshold, let's uplift the priority before it enters into critical region of lock, and restore the priority after it leaves from critical region. Meanwhile, introducing two new sysfs nodes: - /sys/fs/f2fs/<disk>/adjust_lock_priority, it is used to control whether the functionality is enable or not. ========== ================== Flag_Value Flag_Description ========== ================== 0x00000000 Disabled (default) 0x00000001 cp_rwsem 0x00000002 node_change 0x00000004 node_write 0x00000008 gc_lock 0x00000010 cp_global 0x00000020 io_rwsem ========== ================== - /sys/fs/f2fs/<disk>/lock_duration_priority, it is used to control priority threshold.

2026-01-23usb: typec: Expose alternate mode priority via sysfsAndrei Kuchynski1-0/+11
This patch introduces a priority sysfs attribute to the USB Type-C alternate mode port interface. This new attribute allows user-space to configure the numeric priority of alternate modes managing their preferred order of operation. If a new priority value conflicts with an existing mode's priority, the priorities of the conflicting mode and all subsequent modes are automatically incremented to ensure uniqueness.

2026-01-19dma-buf: Remove DMA-BUF sysfs statsT.J. Mercier1-24/+0
Commit bdb8d06dfefd ("dmabuf: Add the capability to expose DMA-BUF stats in sysfs") added dmabuf statistics to sysfs in 2021 under CONFIG_DMABUF_SYSFS_STATS. After being used in production, performance problems were discovered leading to its deprecation in 2022 in commit e0a9f1fe206a ("dma-buf: deprecate DMABUF_SYSFS_STATS"). Some of the problems with this interface were discussed in my LPC 2025 talk. [1][2] Android was probably the last user of the interface, which has since been migrated to use the dmabuf BPF iterator [3] to obtain the same information more cheaply. As promised in that series, now that the longterm stable 6.18 kernel has been released let's remove the sysfs dmabuf statistics from the kernel.

2026-01-15perf/x86/intel: Add support for rdpmc user disable featureDapeng Mi1-0/+44
Starting with Panther Cove, the rdpmc user disable feature is supported. This feature allows the perf system to disable user space rdpmc reads at the counter level. Currently, when a global counter is active, any user with rdpmc rights can read it, even if perf access permissions forbid it (e.g., disallow reading ring 0 counters). The rdpmc user disable feature mitigates this security concern. Details: - A new RDPMC_USR_DISABLE bit (bit 37) in each EVNTSELx MSR indicates that the GP counter cannot be read by RDPMC in ring 3. - New RDPMC_USR_DISABLE bits in IA32_FIXED_CTR_CTRL MSR (bits 33, 37, 41, 45, etc.) for fixed counters 0, 1, 2, 3, etc. - When calling rdpmc instruction for counter x, the following pseudo code demonstrates how the counter value is obtained: If (!CPL0 && RDPMC_USR_DISABLE[x] == 1) ? 0 : counter_value; - RDPMC_USR_DISABLE is enumerated by CPUID.0x23.0.EBX[2]. This patch extends the current global user space rdpmc control logic via the sysfs interface (/sys/devices/cpu/rdpmc) as follows: - rdpmc = 0: Global user space rdpmc and counter-level user space rdpmc for all counters are both disabled. - rdpmc = 1: Global user space rdpmc is enabled during the mmap-enabled time window, and counter-level user space rdpmc is enabled only for non-system-wide events. This prevents counter data leaks as count data is cleared during context switches. - rdpmc = 2: Global user space rdpmc and counter-level user space rdpmc for all counters are enabled unconditionally. The new rdpmc settings only affect newly activated perf events; currently active perf events remain unaffected. This simplifies and cleans up the code. The default value of rdpmc remains unchanged at 1. For more details about rdpmc user disable, please refer to chapter 15 "RDPMC USER DISABLE" in ISE documentation.
