2024-11-21spi-imx: prevent overflow when estimating transfer timeAntonio Quartulli
The words delay is computed by multiplying two unsigned ints and by adding up the result to a u64 variable. The multiplication, however, is performed with 32bit math thus losing data when the actual result is larger than UINT32_MAX. Fix the operation by casting the first operand to u64, thus forcing the multiplication to be performed with 64bit math.

2024-11-21s390/entry: Mark IRQ entries to fix stack depot warningsVasily Gorbik
The stack depot filters out everything outside of the top interrupt context as an uninteresting or irrelevant part of the stack traces. This helps with stack trace de-duplication, avoiding an explosion of saved stack traces that share the same IRQ context code path but originate from different randomly interrupted points, eventually exhausting the stack depot. Filtering uses in_irqentry_text() to identify functions within the .irqentry.text and .softirqentry.text sections, which then become the last stack trace entries being saved. While __do_softirq() is placed into the .softirqentry.text section by common code, populating .irqentry.text is architecture-specific. Currently, the .irqentry.text section on s390 is empty, which prevents stack depot filtering and de-duplication and could result in warnings like: Stack depot reached limit capacity WARNING: CPU: 0 PID: 286113 at lib/stackdepot.c:252 depot_alloc_stack+0x39a/0x3c8 with PREEMPT and KASAN enabled. Fix this by moving the IO/EXT interrupt handlers from .kprobes.text into the .irqentry.text section and updating the kprobes blacklist to include the .irqentry.text section. This is done only for asynchronous interrupts and explicitly not for program checks, which are synchronous and where the context beyond the program check is important to preserve. Despite machine checks being somewhat in between, they are extremely rare, and preserving context when possible is also of value. SVCs and Restart Interrupts are not relevant, one being always at the boundary to user space and the other being a one-time thing. IRQ entries filtering is also optionally used in ftrace function graph, where the same logic applies.

2024-11-21s390/cpum_sf: Simplify release of SDBs and SDBTsThomas Richter
Free_sampling_buffer() releases the Sampling Data Buffers (SDBs) and Sampling Data Buffer Table (SDBTs) allocated at event initialization. Both buffers are of PAGE_SIZE bytes. Each SDBT consists of 512 entries. The first 511 entries point to SDBs the last entry points to a successor SDBT. The last SDBT in the list points to the origin of all SDBTs. SDBTs do not contain holes, that is an entry always points to a SDB. If less than 511 SDBs have been allocation, the last entry points to the origin SDBT. Simplify the release of the SDBs and SDBTs, walk along the SDBT chain, release SDBs and SDBTs and stop when reaching the origin again.

The s390dbf format handler rely on being passed an output buffer sized such that their output will always fit and then use plain sprintf() to write to it. While only supplied data from other kernel components this still potentially allows buffer overwrite if callers are not careful. Instead just pass in the size of the output buffer and use scnprintf() instead of sprintf() and strscpy() instead of strcpy(). The latter also allows us to get rid of a separate strlen() call.

2024-11-21iomap: elide flush from partial eof zero rangeBrian Foster
iomap zero range flushes pagecache in certain situations to determine which parts of the range might require zeroing if dirty data is present in pagecache. The kernel robot recently reported a regression associated with this flushing in the following stress-ng workload on XFS: stress-ng --timeout 60 --times --verify --metrics --no-rand-seed --metamix 64 This workload involves repeated small, strided, extending writes. On XFS, this produces a pattern of post-eof speculative preallocation, conversion of preallocation from delalloc to unwritten, dirtying pagecache over newly unwritten blocks, and then rinse and repeat from the new EOF. This leads to repetitive flushing of the EOF folio via the zero range call XFS uses for writes that start beyond current EOF. To mitigate this problem, special case EOF block zeroing to prefer zeroing the folio over a flush when the EOF folio is already dirty. To do this, split out and open code handling of an unaligned start offset. This brings most of the performance back by avoiding flushes on zero range calls via write and truncate extension operations. The flush doesn't occur in these situations because the entire range is post-eof and therefore the folio that overlaps EOF is the only one in the range.

2024-11-21iomap: reset per-iter state on non-error iter advancesBrian Foster
iomap_iter_advance() zeroes the processed and mapping fields on every non-error iteration except for the last expected iteration (i.e. return 0 expected to terminate the iteration loop). This appears to be circumstantial as nothing currently relies on these fields after the final iteration. Therefore to better faciliate iomap_iter reuse in subsequent patches, update iomap_iter_advance() to always reset per-iteration state on successful completion.

2024-11-21iomap: warn on zero range of a post-eof folioBrian Foster
iomap_zero_range() uses buffered writes for manual zeroing, no longer updates i_size for such writes, but is still explicitly called for post-eof ranges. The historical use case for this is zeroing post-eof speculative preallocation on extending writes from XFS. However, XFS also recently changed to convert all post-eof delalloc mappings to unwritten in the iomap_begin() handler, which means it now never expects manual zeroing of post-eof mappings. In other words, all post-eof mappings should be reported as holes or unwritten. This is a subtle dependency that can be hard to detect if violated because associated codepaths are likely to update i_size after folio locks are dropped, but before writeback happens to occur. For example, if XFS reverts back to some form of manual zeroing of post-eof blocks on write extension, writeback of those zeroed folios will now race with the presumed i_size update from the subsequent buffered write. Since iomap_zero_range() can't correctly zero post-eof mappings beyond EOF without updating i_size, warn if this ever occurs. This serves as minimal indication that if this use case is reintroduced by a filesystem, iomap_zero_range() might need to reconsider i_size updates for write extending use cases.

2024-11-21gpio: exar: set value when external pull-up or pull-down is presentSai Kumar Cholleti
Setting GPIO direction = high, sometimes results in GPIO value = 0. If a GPIO is pulled high, the following construction results in the value being 0 when the desired value is 1: $ echo "high" > /sys/class/gpio/gpio336/direction $ cat /sys/class/gpio/gpio336/value 0 Before the GPIO direction is changed from an input to an output, exar_set_value() is called with value = 1, but since the GPIO is an input when exar_set_value() is called, _regmap_update_bits() reads a 1 due to an external pull-up. regmap_set_bits() sets force_write = false, so the value (1) is not written. When the direction is then changed, the GPIO becomes an output with the value of 0 (the hardware default). regmap_write_bits() sets force_write = true, so the value is always written by exar_set_value() and an external pull-up doesn't affect the outcome of setting direction = high. The same can happen when a GPIO is pulled low, but the scenario is a little more complicated. $ echo high > /sys/class/gpio/gpio351/direction $ cat /sys/class/gpio/gpio351/value 1 $ echo in > /sys/class/gpio/gpio351/direction $ cat /sys/class/gpio/gpio351/value 0 $ echo low > /sys/class/gpio/gpio351/direction $ cat /sys/class/gpio/gpio351/value 1 Fixes: 36fb7218e878 ("gpio: exar: switch to using regmap") Co-developed-by: Matthew McClain <mmcclain@noprivs.com> Signed-off-by: Matthew McClain <mmcclain@noprivs.com> Signed-off-by: Sai Kumar Cholleti <skmr537@gmail.com> Cc: stable@vger.kernel.org Reviewed-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Link: https://lore.kernel.org/r/20241105071523.2372032-1-skmr537@gmail.com Signed-off-by: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>

git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux Pull gpio updates from Bartosz Golaszewski: "Three new drivers, support for some new models in existing ones and lots of various tweaks and improvements across the board (switching to using recommended APIs, code shrink and simplification, etc.). Also a new feature in the character device uAPI where we now notify the user-space about changes triggered by in-kernel users as well, not only when they were done by other user-space agents. Summary: GPIOLIB core: - use the new mem_is_zero() instead of memchr_inv(s, 0, n) - don't store debounce period twice needlessly - clean-up debugfs handling - remove leftover comments referring to no longer used spinlocks - unduplicate some operations like SRCU locks and initializing GPIO descriptors - constify the sysfs class struct - use lock guards in GPIO sysfs code - update GPIO uAPI internal flags all at once atomically for consistency with other places - modify the behavior of the sysfs interface by no longer exporting lines that are named inside the driver code or board files with the sysfs links bearing the line names as this has for many years been largely unused due to the prevalence of DT, ACPI and firmware nodes over board files and made the API inconsistent - for GPIO interrupt providers: free irqs that are still requested by users when removing the chip GPIO uAPI: - notify user-space about changes to GPIO lines' state (requested, released, reconfigured) triggered from the kernel as well (until now we'd only do this for changes triggered from user-space) - to that end: modify the internal workings of the notification mechanism by switching to an atomic notifier which allows us to send events from atomic context - also to that end store the debounce period in the GPIO descriptor struct and not in the character device context struct - while at it, also cover the corner-case of users introducing changes over sysfs while others watch them via the character device - don't report GPIO lines requested as interrupts as "used" to user-space as it can still request them as GPIOs New drivers: - GPIO part of the MFD Congatec Board Controller - PolarFire GPIO controller - GPIOs on FTDI FT2232H Driver improvements: - use generic device property accessors instead of OF-specific ones across many GPIO drivers (mpc8xxx, vf610, eic-sprd, davinci, ts4900, xilinx, mvebu) - use devres helpers to simplify error paths and either shrink or entirely remove the driver's remove() callback (grgpio, amdpt, menz127, max730x, ftgpio010, 74x164, ljca) - use helper variables to store the address of pdev->dev and avoid some line-breaks - use device_for_each_child_node_scoped() to avoid having to put the fwnode on breaks or errors (gpio-sim, gpio-dwapb, gpiolib-acpi) - use a scoped bitmap to simplify the code and drop goto labels in gpio-aggregator - drop unneeded Kconfig dependencies on OF_GPIO (grgpio, mveby, xilinx) - add support for new models to gpio-aspeed, gpio-rockchip and gpio-dwapb - clean-up ACPI handling and some other bits in gpio-xgene-sb - replace deprecated PCI functions in pcie-idio-24 and pci-idio-16 - allow to build davinci and mvebu drivers with COMPILE_TEST=y - remove dead code in gpio-mb86s7x - switch back to using platform_driver::remove() (after the conversion to remove_new()) across the GPIO drivers - remove remaining uses of GPIOF_ACTIVE_LOW across the tree and drop this deprecated symbol - convert the gpio-altera driver to no longer pull in the deprecated legacy-of-mm-gpiochip.h header - use of_property_present() instead of of_property_read_bool() in gpiolib-of and gpio-rockchip - allow to build the tegra186 driver on Tegra234 platforms in Kconfig Late fixes: - add a missing return value check after devm_kasprintf() to gpio-grgpio DT bindings: - document the ngpios property of gpio-mmio - add support for a new aspeed model - fix the example for st,nomadik-gpio Other: - kernel doc and comments tweaks - fix typos in TODO - reorder headers alphabetically in some drivers - fix incorrect format specifiers in gpio tools" * tag 'gpio-updates-for-v6.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux: (98 commits) gpio: tegra186: Allow to enable driver on Tegra234 gpio: grgpio: Add NULL check in grgpio_probe tools: gpio: Fix several incorrect format specifiers gpio: mpfs: add CoreGPIO support gpio: rockchip: support new version GPIO gpio: rockchip: change the GPIO version judgment logic gpio: rockchip: explan the format of the GPIO version ID gpiolib: cdev: use !mem_is_zero() instead of memchr_inv(s, 0, n) MAINTAINERS: add gpio driver to PolarFire entry gpio: Get rid of GPIOF_ACTIVE_LOW USB: gadget: pxa27x_udc: Avoid using GPIOF_ACTIVE_LOW pcmcia: soc_common: Avoid using GPIOF_ACTIVE_LOW leds: gpio: Avoid using GPIOF_ACTIVE_LOW Input: gpio_keys_polled - avoid using GPIOF_ACTIVE_LOW Input: gpio_keys - avoid using GPIOF_ACTIVE_LOW gpio: Use of_property_present() for non-boolean properties gpio: mpfs: add polarfire soc gpio support gpio: altera: Drop legacy-of-mm-gpiochip.h header gpio: pcie-idio-24: Replace deprecated PCI functions gpio: pci-idio-16: Replace deprecated PCI functions ...

The new API requires changes to the lowlevel drivers. For now there are two drivers that are converted to the new API (axi-pwmgen and stm32). Converted drivers continue to work with the old API. Drivers not yet converted only work with the older API. Otherwise it's the usual collection of fixes, cleanups and dt doc updates.

git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull ftrace updates from Steven Rostedt: - Restructure the function graph shadow stack to prepare it for use with kretprobes With the goal of merging the shadow stack logic of function graph and kretprobes, some more restructuring of the function shadow stack is required. Move out function graph specific fields from the fgraph infrastructure and store it on the new stack variables that can pass data from the entry callback to the exit callback. Hopefully, with this change, the merge of kretprobes to use fgraph shadow stacks will be ready by the next merge window. - Make shadow stack 4k instead of using PAGE_SIZE. Some architectures have very large PAGE_SIZE values which make its use for shadow stacks waste a lot of memory. - Give shadow stacks its own kmem cache. When function graph is started, every task on the system gets a shadow stack. In the future, shadow stacks may not be 4K in size. Have it have its own kmem cache so that whatever size it becomes will still be efficient in allocations. - Initialize profiler graph ops as it will be needed for new updates to fgraph - Convert to use guard(mutex) for several ftrace and fgraph functions - Add more comments and documentation - Show function return address in function graph tracer Add an option to show the caller of a function at each entry of the function graph tracer, similar to what the function tracer does. - Abstract out ftrace_regs from being used directly like pt_regs ftrace_regs was created to store a partial pt_regs. It holds only the registers and stack information to get to the function arguments and return values. On several archs, it is simply a wrapper around pt_regs. But some users would access ftrace_regs directly to get the pt_regs which will not work on all archs. Make ftrace_regs an abstract structure that requires all access to its fields be through accessor functions. - Show how long it takes to do function code modifications When code modification for function hooks happen, it always had the time recorded in how long it took to do the conversion. But this value was never exported. Recently the code was touched due to new ROX modification handling that caused a large slow down in doing the modifications and had a significant impact on boot times. Expose the timings in the dyn_ftrace_total_info file. This file was created a while ago to show information about memory usage and such to implement dynamic function tracing. It's also an appropriate file to store the timings of this modification as well. This will make it easier to see the impact of changes to code modification on boot up timings. - Other clean ups and small fixes * tag 'ftrace-v6.13' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: (22 commits) ftrace: Show timings of how long nop patching took ftrace: Use guard to take ftrace_lock in ftrace_graph_set_hash() ftrace: Use guard to take the ftrace_lock in release_probe() ftrace: Use guard to lock ftrace_lock in cache_mod() ftrace: Use guard for match_records() fgraph: Use guard(mutex)(&ftrace_lock) for unregister_ftrace_graph() fgraph: Give ret_stack its own kmem cache fgraph: Separate size of ret_stack from PAGE_SIZE ftrace: Rename ftrace_regs_return_value to ftrace_regs_get_return_value selftests/ftrace: Fix check of return value in fgraph-retval.tc test ftrace: Use arch_ftrace_regs() for ftrace_regs_*() macros ftrace: Consolidate ftrace_regs accessor functions for archs using pt_regs ftrace: Make ftrace_regs abstract from direct use fgragh: No need to invoke the function call_filter_check_discard() fgraph: Simplify return address printing in function graph tracer function_graph: Remove unnecessary initialization in ftrace_graph_ret_addr() function_graph: Support recording and printing the function return address ftrace: Have calltime be saved in the fgraph storage ftrace: Use a running sleeptime instead of saving on shadow stack fgraph: Use fgraph data to store subtime for profiler ...
