2025-03-28seq_file: Mark binary printing functions with __printf() attributeAndy Shevchenko
Binary printing functions are using printf() type of format, and compiler is not happy about them as is: fs/seq_file.c:418:35: error: function ‘seq_bprintf’ might be a candidate for ‘gnu_printf’ format attribute [-Werror=suggest-attribute=format] Fix the compilation errors by adding __printf() attribute.

2025-03-28iomap: Fix conflicting values of iomap flagsRitesh Harjani (IBM)
IOMAP_F_ATOMIC_BIO mistakenly took the same value as of IOMAP_F_SIZE_CHANGED in patch '370a6de7651b ("iomap: rework IOMAP atomic flags")'. Let's fix this and let's also create some more space for filesystem reported flags to avoid this in future. This patch makes the core iomap flags to start from bit 15, moving downwards. Note that "flags" member within struct iomap is of type u16.

git://git.kernel.org/pub/scm/linux/kernel/git/printk/linux Pull printk updates from Petr Mladek: - New option "printk.debug_non_panic_cpus" allows to store printk messages from non-panic CPUs during panic. It might be useful when panic() fails. It is disabled by default because it increases the chance to see the messages printed before panic() and on the panic-CPU. - New build option "CONFIG_NULL_TTY_DEFAULT_CONSOLE" allows to build kernel without the virtual terminal support which prefers ttynull over serial console. - Do not unblank suspended consoles. - Some code clean up. * tag 'printk-for-6.15' of git://git.kernel.org/pub/scm/linux/kernel/git/printk/linux: printk/panic: Add option to allow non-panic CPUs to write to the ring buffer. printk: Add an option to allow ttynull to be a default console device printk: Check CON_SUSPEND when unblanking a console printk: Rename console_start to console_resume printk: Rename console_stop to console_suspend printk: Rename resume_console to console_resume_all printk: Rename suspend_console to console_suspend_all

git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing updates from Steven Rostedt: - Add option traceoff_after_boot In order to debug kernel boot, it sometimes is helpful to enable tracing via the kernel command line. Unfortunately, by the time the login prompt appears, the trace is overwritten by the init process and other user space start up applications. Adding a "traceoff_after_boot" will disable tracing when the kernel passes control to init which will allow developers to be able to see the traces that occurred during boot. - Clean up the mmflags macros that display the GFP flags in trace events The macros to print the GFP flags for trace events had a bit of duplication. The code was restructured to remove duplication and in the process it also adds some flags that were missed before. - Removed some dead code and scripts/draw_functrace.py draw_functrace.py hasn't worked in years and as nobody complained about it, remove it. - Constify struct event_trigger_ops The event_trigger_ops is just a structure that has function pointers that are assigned when the variables are created. These variables should all be constants. - Other minor clean ups and fixes * tag 'trace-v6.15' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: tracing: Replace strncpy with memcpy for fixed-length substring copy tracing: Fix synth event printk format for str fields tracing: Do not use PERF enums when perf is not defined tracing: Ensure module defining synth event cannot be unloaded while tracing tracing: fix return value in __ftrace_event_enable_disable for TRACE_REG_UNREGISTER tracing/osnoise: Fix possible recursive locking for cpus_read_lock() tracing: Align synth event print fmt tracing: gfp: vsprintf: Do not print "none" when using %pGg printf format tracepoint: Print the function symbol when tracepoint_debug is set tracing: Constify struct event_trigger_ops scripts/tracing: Remove scripts/tracing/draw_functrace.py tracing: Update MAINTAINERS file to include tracepoint.c tracing/user_events: Slightly simplify user_seq_show() tracing/user_events: Don't use %pK through printk tracing: gfp: Remove duplication of recording GFP flags tracing: Remove orphaned event_trace_printk ring-buffer: Fix typo in comment about header page pointer tracing: Add traceoff_after_boot option

git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull latency tracing updates from Steven Rostedt: - Add some trace events to osnoise and timerlat sample generation This adds more information to the osnoise and timerlat tracers as well as allows BPF programs to be attached to these locations to extract even more data. - Fix to DECLARE_TRACE_CONDITION() macro It wasn't used but now will be and it happened to be broken causing the build to fail. - Add scheduler specification monitors to runtime verifier (RV) This is a continuation of Daniel Bristot's work. RV allows monitors to run and react concurrently. Running the cumulative model is equivalent to running single components using the same reactors, with the advantage that it's easier to point out which specification failed in case of error. This update introduces nested monitors to RV, in short, the sysfs monitor folder will contain a monitor named sched, which is nothing but an empty container for other monitors. Controlling the sched monitor (enable, disable, set reactors) controls all nested monitors. The following scheduling monitors are added: - sco: scheduling context operations Monitor to ensure sched_set_state happens only in thread context - tss: task switch while scheduling Monitor to ensure sched_switch happens only in scheduling context - snroc: set non runnable on its own context Monitor to ensure set_state happens only in the respective task's context - scpd: schedule called with preemption disabled Monitor to ensure schedule is called with preemption disabled - snep: schedule does not enable preempt Monitor to ensure schedule does not enable preempt - sncid: schedule not called with interrupt disabled Monitor to ensure schedule is not called with interrupt disabled * tag 'trace-latency-v6.15' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: tools/rv: Allow rv list to filter for container Documentation/rv: Add docs for the sched monitors verification/dot2k: Add support for nested monitors tools/rv: Add support for nested monitors rv: Add scpd, snep and sncid per-cpu monitors rv: Add snroc per-task monitor rv: Add sco and tss per-cpu monitors rv: Add option for nested monitors and include sched sched: Add sched tracepoints for RV task model rv: Add license identifiers to monitor files tracing: Fix DECLARE_TRACE_CONDITION trace/osnoise: Add trace events for samples

git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull ftrace updates from Steven Rostedt: - Record function parameters for function and function graph tracers An option has been added to function tracer (func-args) and the function graph tracer (funcgraph-args) that when set, the tracers will record the registers that hold the arguments into each function event. On reading of the trace, it will use BTF to print those arguments. Most archs support up to 6 arguments (depending on the complexity of the arguments) and those are printed. If a function has more arguments then what was recorded, the output will end with " ... )". Example of function graph tracer: 6) | dummy_xmit [dummy](skb = 0x8887c100, dev = 0x872ca000) { 6) | consume_skb(skb = 0x8887c100) { 6) | skb_release_head_state(skb = 0x8887c100) { 6) 0.178 us | sock_wfree(skb = 0x8887c100) 6) 0.627 us | } - The rest of the changes are minor clean ups and fixes * tag 'ftrace-v6.15' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: tracing: Use hashtable.h for event_hash tracing: Fix use-after-free in print_graph_function_flags during tracer switching function_graph: Remove the unused variable func ftrace: Add arguments to function tracer ftrace: Have funcgraph-args take affect during tracing ftrace: Add support for function argument to graph tracer ftrace: Add print_function_args() ftrace: Have ftrace_free_filter() WARN and exit if ops is active fgraph: Correct typo in ftrace_return_to_handler comment

2025-03-27tpm, tpm_tis: Workaround failed command reception on Infineon devicesJonathan McDowell
Some Infineon devices have a issue where the status register will get stuck with a quick REQUEST_USE / COMMAND_READY sequence. This is not simply a matter of requiring a longer timeout; the work around is to retry the command submission. Add appropriate logic to do this in the send path. This is fixed in later firmware revisions, but those are not always available, and cannot generally be easily updated from outside a firmware environment. Testing has been performed with a simple repeated loop of doing a TPM2_CC_GET_CAPABILITY for TPM_CAP_PROP_MANUFACTURER using the Go code at: https://the.earth.li/~noodles/tpm-stuff/timeout-reproducer-simple.go It can take several hours to reproduce, and several million operations.

From: Tomasz Pakuła <tomasz.pakula.oficjalny@gmail.com> This patch series is focused on improving the compatibility and usability of the hid-pidff force feedback driver. Last patch introduces a new, universal driver for PID devices that need some special handling like report fixups, remapping the button range, managing new pidff quirks and setting desirable fuzz/flat values. This work has been done in the span of the past months with the help of the great Linux simracing community, with a little input from sim flight fans from FFBeast. No changes interfere with compliant and currently working PID devices. "Generic" codepath was tested as well with Moza and Simxperience AccuForce v2. I'm not married to the name. It's what we used previously, but if "universal" is confusing (pidff is already the generic driver), we can come up with something better like "hid-quirky-pidff" :) With v8 and tiny finx in v9, all the outstanding issues were resolved, additional pidff issues were fixed and hid-pidff defines moved to a dedicated header file. This patch series could be considered done bar any comments and requests from input maintainers. I could save more then a dozen lines of code by changing simple if statements to only occupy on line instead of two in there's a need for that.

2025-03-26PCI: endpoint: Add intx_capable to epc_features structNiklas Cassel
In struct pci_epc_features, an EPC driver can already specify if they support MSI (by setting msi_capable) and MSI-X (by setting msix_capable). Thus, for consistency, allow an EPC driver to specify if it supports INTx interrupts as well (by setting intx_capable). Since this struct is zero initialized, EPC drivers that want to claim INTx support will need to set intx_capable to true.

git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux Pull gpio updates from Bartosz Golaszewski: "There are no new drivers this time but several changes to the core GPIO framework and various driver updates. This release cycle, we're starting a relatively straightforward but tedious rework of the GPIO consumer API: for historical reasons, the gpiod_set_value() variants would return void. Not only that but the GPIO provider interface does not even allow drivers to return a value to GPIO core. This is because initial GPIO controllers would be MMIO based and could not fail. We've had I2C, SPI and USB controllers for years too but no way of indicating failures to callers. This changes the consumer interface, adds new provider callbacks and starts converting the drivers under drivers/gpio/ to using them. Once this gets upstream, we'll keep on converting GPIO drivers that live elsewhere and once there are no more users of the old callbacks, we'll remove them and rename the new ones to the previous name. I imagine the last step would happen in one sweeping change like what you did for the remove_new() -> remove() renaming. We've also addressed an issue where invalid return values from GPIO drivers would get propagated to user-space by adding some GPIO-core-level sanitization. Again: not a complex change but way overdue. Other than that: lots of driver and core refactoring, DT-bindings changes and some other minor changes like coding style fixes or header reordering. GPIO core: - add sanitization of return values of GPIO provider callbacks so that invalid ones don't get propagated to user-space - add new variants of the line setter callbacks for GPIO providers that return an integer and allow to indicate driver errors to the GPIO core - change the interface of all gpiod_set_value() variants to return an integer thus becoming able to indicate failures in the underlying layer to callers - drop unneeded ERR_CAST in gpiolib-acpi - use for_each_if() where applicable - provide gpiod_multi_set_value_cansleep() as a new, simpler interface to gpiod_set_array_value_cansleep() and use it across several drivers treewide - reduce the number of atomic reads of the descriptor flags in gpiolib debugfs code - simplify for_each_hwgpio_in_range() and for_each_requested_gpio_in_range() - add support for three-cell GPIO specifiers in GPIO OF code - don't build HTE (hardware timestamp engine) GPIO code with the HTE subsystem disabled in Kconfig - unduplicate calls to gpiod_direction_input_nonotify() - rework the handling of the valid_mask property of GPIO chips: don't allow drivers to set it as it should only be handled by GPIO core and start actually enforcing it in GPIO core for *all* drivers, not only the ones implementing a custom request() callback - get the `ngpios` property from the fwnode of the GPIO chip, not its device in order to handle multi-bank GPIO chips Driver improvements: - convert a part of the GPIO drivers under drivers/gpio/ to using the new value setter callbacks - convert several drivers to using automatic lock guards from cleanup.h - allow building gpio-bt8xx with COMPILE_TEST=y - refactor gpio-74x164 (use devres, cleanup helpers, __counted_by() and bits.h macros) - refactor gpio-latch (use generic device properties, lock guards and some local variables for better readability) - refactor gpio-xilinx (improve the usage of the bitmap API) - support multiple virtual GPIO controller instances in gpio-virtio - allow gpio-regmap to use the standard `ngpios` property from GPIOLIB - factor out the common code for synchronous probing of virtual GPIO devices into its own library - use str_enable_disable(), str_high_low() and other string helpers where applicable - extend the gpio-mmio abstraction layer to allow calling into the pinctrl back-end when setting direction - convert gpio-vf610 to using the gpio-mmio library - use more devres in gpio-adnp - add support for reset-gpios in gpio-pcf857x - add support for more models to gpio-loongson-64bit DT bindings: - add new compatibles to gpio-vf610 and gpio-loongson - add missing gpio-ranges property to gpio-mvebu - add reset-gpios to nxp,pcf8575 - enable gpio-hog parsing in ast2400-gpio Misc: - coding style improvements - kerneldoc fixes - includes reordering - updates to the TODO list" * tag 'gpio-updates-for-v6.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux: (119 commits) gpio: TODO: add an item to track reworking the sysfs interface gpio: TODO: add an item to track the conversion to the new value setters gpio: TODO: add delimiters between tasks for better readability gpio: TODO: remove the pinctrl integration task gpio: TODO: remove task duplication gpio: TODO: remove the item about the new debugfs interface gpio: da9055: use new line value setter callbacks gpio: da9052: use new line value setter callbacks gpio: cs5535: use new line value setter callbacks gpio: crystalcove: use new line value setter callbacks gpio: cros-ec: use new line value setter callbacks gpio: creg-snps: use new line value setter callbacks gpio: cgbc: use new line value setter callbacks gpio: bt8xx: use new line value setter callbacks gpio: bt8xx: use lock guards gpio: bt8xx: allow to build the module with COMPILE_TEST=y gpio: bd9571mwv: use new line value setter callbacks gpio: bd71828: use new line value setter callbacks gpio: bd71815: use new line value setter callbacks gpio: bcm-kona: use new line value setter callbacks ...

Otherwise there's the usual fixes, improvements and cleanups, plus support for a bunch of new devices. - Support for offloading support from David Lechner - Support for GOcontrol1 Moduline modules, Mediatek MT7988, NXP i.MX94, Qualcomm SPI NAMD, Rockchip RK3562, Sophogo SG2044 and ST STM32 OSPI" * tag 'spi-v6.15' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi: (59 commits) spi: spi-mem: Introduce a default ->exec_op() debug log spi: dt-bindings: cdns,qspi-nor: Require some peripheral properties spi: dt-bindings: cdns,qspi-nor: Deprecate the Cadence compatible alone spi: dt-bindings: cdns,qspi-nor: Be more descriptive regarding what this controller is spi: stm32-ospi: Include "gpio/consumer.h" MAINTAINERS: adjust the file entry in GOCONTROLL MODULINE MODULE SLOT spi: spi-qpic-snand: avoid memleak in qcom_spi_ecc_init_ctx_pipelined() spi: spi-mux: Fix coverity issue, unchecked return value spi: sophgo: fix incorrect type for ret in sg2044_spifmc_write() spi: sg2044-nor: fix uninitialized variable in probe spi: sg2044-nor: fix signedness bug in sg2044_spifmc_write() spi: sg2044-nor: Convert to dev_err_probe() spi: sg2044-nor: Fully convert to device managed resources dt-bindings: spi: add compatibles for mt7988 spi: spidev: Add an entry for the gocontroll moduline module slot MAINTAINERS: add maintainer for the GOcontroll Moduline module slot dt-bindings: connector: Add the GOcontroll Moduline module slot bindings dt-bindings: vendor-prefixes: add GOcontroll spi: Use inclusive language spi: cadence-qspi: Improve spi memory performance ...

git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator Pull regulator updates from Mark Brown: "This has been a very quiet release, we've got support for one device added, another removed, and some smaller fixes and API improvements. The main thing of note is the rework of the PCA9450 LDO5 handling. - A rework of the handling of LDO5 on the PCA9450, this was quite wrong in how it handled the SD_VSEL conrol and only worked for some system designs. This includes a DTS update since there was a not quite ABI compatible change as part of the fix - A devres change introducing devm_kmemdup_array() was pulled in so it could be used with some regulator conversions to that function, this pulled in some other devres and IIO stuff that was part of the same pull request - Removal of the PCF50633 driver, the SoC for the OpenMoko platform that used it has been removed - Support for the NXP PF9453" * tag 'regulator-v6.15' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator: (24 commits) regulator: axp20x: AXP717: dcdc4 doesn't have delay regulator: dt-bindings: rtq2208: Cleanup whitespace regulator: dt-bindings: rtq2208: Mark fixed LDO VOUT property as deprecated regulator: rtq6752: make const read-only array fault_mask static regulator: pf9453: add PMIC PF9453 support regulator: dt-bindings: pca9450: Add nxp,pf9453 compatible string regulator: pcf50633-regulator: Remove regulator: pca9450: Handle hardware with fixed SD_VSEL for LDO5 regulator: cros-ec: use devm_kmemdup_array() regulator: devres: use devm_kmemdup_array() regulator: Add (devm_)of_regulator_get() devres: Introduce devm_kmemdup_array() iio: imu: st_lsm9ds0: Replace device.h with what is needed driver core: Split devres APIs to device/devres.h err.h: move IOMEM_ERR_PTR() to err.h regulator: pca9450: Remove duplicate code in probe regulator: ad5398: Fix incorrect power down bit mask regulator: pca9450: Fix enable register for LDO5 regulator: pca9450: Fix control register for LDO5 Revert "regulator: pca9450: Add SD_VSEL GPIO for LDO5" ...

git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/lsm Pull lsm updates from Paul Moore: - Various minor updates to the LSM Rust bindings Changes include marking trivial Rust bindings as inlines and comment tweaks to better reflect the LSM hooks. - Add LSM/SELinux access controls to io_uring_allowed() Similar to the io_uring_disabled sysctl, add a LSM hook to io_uring_allowed() to enable LSMs a simple way to enforce security policy on the use of io_uring. This pull request includes SELinux support for this new control using the io_uring/allowed permission. - Remove an unused parameter from the security_perf_event_open() hook The perf_event_attr struct parameter was not used by any currently supported LSMs, remove it from the hook. - Add an explicit MAINTAINERS entry for the credentials code We've seen problems in the past where patches to the credentials code sent by non-maintainers would often languish on the lists for multiple months as there was no one explicitly tasked with the responsibility of reviewing and/or merging credentials related code. Considering that most of the code under security/ has a vested interest in ensuring that the credentials code is well maintained, I'm volunteering to look after the credentials code and Serge Hallyn has also volunteered to step up as an official reviewer. I posted the MAINTAINERS update as a RFC to LKML in hopes that someone else would jump up with an "I'll do it!", but beyond Serge it was all crickets. - Update Stephen Smalley's old email address to prevent confusion This includes a corresponding update to the mailmap file. * tag 'lsm-pr-20250323' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/lsm: mailmap: map Stephen Smalley's old email addresses lsm: remove old email address for Stephen Smalley MAINTAINERS: add Serge Hallyn as a credentials reviewer MAINTAINERS: add an explicit credentials entry cred,rust: mark Credential methods inline lsm,rust: reword "destroy" -> "release" in SecurityCtx lsm,rust: mark SecurityCtx methods inline perf: Remove unnecessary parameter of security check lsm: fix a missing security_uring_allowed() prototype io_uring,lsm,selinux: add LSM hooks for io_uring_setup() io_uring: refactor io_uring_allowed()
