We mark ctx->task with TASK_TOMBSTONE to indicate a context is 'dead', under ctx->lock. After which point event_function_call() on any event of that context will NOP A concurrent orphans_remove_work() will only hold ctx->mutex for the list iteration and not serialize against this. Therefore its possible that orphans_remove_work()'s perf_remove_from_context() call will fail, but we'll continue to free the event, with the result of free'd memory still being on lists and everything. Once perf_event_exit_task_context() gets around to acquiring ctx->mutex it too will iterate the event list, encounter the already free'd event and proceed to free it _again_. This fails with the WARN in free_event(). Plug the race by having perf_event_exit_task_context() hold ctx::mutex over the whole tear-down, thereby 'naturally' serializing against all other sites, including the orphan work.

Currently, gdb does that for allocating AUX buffers for Intel PT traces. More specifically, overwrite mode of AUX pmus that don't support hardware sg (some implementations of Intel PT, for instance) is limited to only one contiguous high order allocation for its buffer and there is no way of knowing its size without trying. This patch changes error path freeing to be synchronous as there won't be any contenders for the AUX pages at that point.

| 39a4364 | Peter Zijlstra | 11 January 2016, 11:46:35 UTC | perf: Fix task context scheduling There is a very nasty problem wrt disabling the perf task scheduling hooks. Currently we {set,clear} ctx->is_active on every __perf_event_task_sched_{in,out}, _however_ this means that if we disable these calls we'll have task contexts with ->is_active set that are not active and 'active' task contexts without ->is_active set. This can result in event_function_call() looping on the ctx->is_active condition basically indefinitely. Resolve this by changing things such that contexts without events do not set ->is_active like we used to. From this invariant it trivially follows that if there are no (task) events, every task ctx is inactive and disabling the context switch hooks is harmless. This leaves two places that need attention (and already had accumulated weird and wonderful hacks to work around, without recognising this actual problem). Namely: - perf_install_in_context() will need to deal with installing events in an inactive context, meaning it cannot rely on ctx-is_active for its IPIs. - perf_remove_from_context() will have to mark a context as inactive when it removes the last event.

| 3caeaa5 | Ravi Bangoria | 07 December 2015, 06:55:02 UTC | perf kvm record/report: 'unprocessable sample' error while recording/reporting guest data While recording guest samples in host using perf kvm record, it will populate unprocessable sample error, though samples will be recorded properly. While generating report using perf kvm report, no samples will be processed and same error will populate. We have seen this behaviour with upstream perf(4.4-rc3) on x86 and ppc64 hardware. Reason behind this failure is, when it tries to fetch machine from rb_tree of machines, it fails. As a part of tracing a bug, we figured out that this code was incorrectly refactored in commit 54245fdc3576 ("perf session: Remove wrappers to machines__find"). This patch will change the functionality such that if it can't fetch machine in first trial, it will create one node of machine and add that to rb_tree. So next time when it tries to fetch same machine from rb_tree, it won't fail. Actually it was the case before refactoring of code in aforementioned commit. This patch is generated from acme perf/core branch. Below I've mention an example that demonstrate the behaviour before and after applying patch. Before applying patch: [Note: One needs to run guest before recording data in host] ravi@ravi-bangoria:~$ ./perf kvm record -a Warning: 5903 unprocessable samples recorded.

The 'for-4.5/block- dax' topic branch was rebased over the weekend to drop the "block device end-of-life" rework that Al would like to see re-implemented with a notifier, and to address bug reports against the badblocks integration. There is pending feedback against "libnvdimm: Add a poison list and export badblocks" received last week. Linda identified some localized fixups that we will handle incrementally. Summary: - Media error handling: The 'badblocks' implementation that originated in md-raid is up-levelled to a generic capability of a block device. This initial implementation is limited to being consulted in the pmem block-i/o path. Later, 'badblocks' will be consulted when creating dax mappings. - Raw block device dax: For virtualization and other cases that want large contiguous mappings of persistent memory, add the capability to dax-mmap a block device directly. - Increased /dev/mem restrictions: Add an option to treat all io-memory as IORESOURCE_EXCLUSIVE, i.e. disable /dev/mem access while a driver is actively using an address range. This behavior is controlled via the new CONFIG_IO_STRICT_DEVMEM option and can be overridden by the existing "iomem=relaxed" kernel command line option. - Miscellaneous fixes include a 'pfn'-device huge page alignment fix, block device shutdown crash fix, and other small libnvdimm fixes" * tag 'libnvdimm-for-4.5' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm: (32 commits) block: kill disk_{check|set|clear|alloc}_badblocks libnvdimm, pmem: nvdimm_read_bytes() badblocks support pmem, dax: disable dax in the presence of bad blocks pmem: fail io-requests to known bad blocks libnvdimm: convert to statically allocated badblocks libnvdimm: don't fail init for full badblocks list block, badblocks: introduce devm_init_badblocks block: clarify badblocks lifetime badblocks: rename badblocks_free to badblocks_exit libnvdimm, pmem: move definition of nvdimm_namespace_add_poison to nd.h libnvdimm: Add a poison list and export badblocks nfit_test: Enable DSMs for all test NFITs md: convert to use the generic badblocks code block: Add badblock management for gendisks badblocks: Add core badblock management code block: fix del_gendisk() vs blkdev_ioctl crash block: enable dax for raw block devices block: introduce bdev_file_inode() restrict /dev/mem to idle io memory ranges arch: consolidate CONFIG_STRICT_DEVM in lib/Kconfig.debug ... | 14 January 2016, 03:15:14 UTC |

It also contains patches to enable media controller support at the DVB subsystem. The goal is to improve the media controller to allow proper support for other types of Video4Linux devices (radio and TV ones) and to extend the media controller functionality to allow it to be used by other subsystems like DVB, ALSA and IIO. In order to use the new functionality, a new ioctl is needed (MEDIA_IOC_G_TOPOLOGY). As we're still discussing how to pack the struct fields of this ioctl in order to avoid compat32 issues, I decided to add a patch at the end of this series commenting out the new ioctl, in order to postpone the addition of the new ioctl to the next Kernel version (4.6). With that, no userspace visible changes should happen at the media controller API, as the existing ioctls are untouched.

Commit f7d924894265 ("arm64/efi: refactor EFI init and runtime code for reuse by 32-bit ARM") attempted to work around this by including asm/efi.h, which transitively includes asm/early_ioremap.h on most architectures. However, since asm/efi.h does not exist on ia64 either, this is not much of an improvement. Now that we have created an asm/early_ioremap.h for ia64, we can just include it directly.

| c698d63 | Paul Gortmaker | 13 December 2015, 20:33:19 UTC | i2c: create builtin_i2c_driver to avoid registration boilerplate In commit f309d4443130bf814e991f836e919dca22df37ae ("platform_device: better support builtin boilerplate avoidance") we introduced the builtin_driver macro. Here we use that support and extend it to I2C driver registration, so where a driver is clearly non-modular and builtin-only, we can register it in a similar fashion. And existing code that is clearly non-modular can be updated with the simple mapping of module_i2c_driver(...) ---> builtin_i2c_driver(...) We've essentially cloned the former to make the latter, and taken out the remove/module_exit parts since those never get used in a non-modular build of the code. A similar thing was done in commit b4eb6cdbbd13698704863f680c643c569909e1c2 ("PCI: Add builtin_pci_driver() to avoid registration boilerplate").

The most significant new feature is the debugfs-based interface to the ACPICA's AML debugger added in the previous cycle and a new user space tool for accessing it. On the cpufreq front, the core is updated to handle governors more efficiently, particularly on systems where a single cpufreq policy object is shared between multiple CPUs, and there are quite a few changes in drivers (intel_pstate, cpufreq-dt etc). The device properties framework is updated to handle built-in (ie included in the kernel itself) device properties better, among other things by adding a fallback mechanism that will allow drivers to provide default properties to be used in case the plaform firmware doesn't provide the properties expected by them. The Operating Performance Points (OPP) framework gets new DT bindings and debugfs support. A new cpufreq driver for ST platforms is added and the ACPI driver for AMD SoCs will now support the APM X-Gene ACPI I2C device. The rest is mostly fixes and cleanups all over. Specifics: - Add a debugfs-based interface for interacting with the ACPICA's AML debugger introduced in the previous cycle and a new user space tool for that, fix some bugs related to the AML debugger and clean up the code in question (Lv Zheng, Dan Carpenter, Colin Ian King, Markus Elfring). - Update ACPICA to upstream revision 20151218 including a number of fixes and cleanups in the ACPICA core (Bob Moore, Lv Zheng, Labbe Corentin, Prarit Bhargava, Colin Ian King, David E Box, Rafael Wysocki). In particular, the previously added erroneous support for the _SUB object is dropped, the concatenate operator will support all ACPI objects now, the Debug Object handling is improved, the SuperName handling of parameters being control methods is fixed, the ObjectType operator handling is updated to follow ACPI 5.0A and the handling of CondRefOf and RefOf is updated accordingly, module- level code will be executed after loading each ACPI table now (instead of being run once after all tables containing AML have been loaded), the Operation Region handlers management is updated to fix some reported problems and a the ACPICA code in the kernel is more in line with the upstream now. - Update the ACPI backlight driver to provide information on whether or not it will generate key-presses for brightness change hotkeys and update some platform drivers (dell-wmi, thinkpad_acpi) to use that information to avoid sending double key-events to users pace for these, add new ACPI backlight quirks (Hans de Goede, Aaron Lu, Adrien Schildknecht). - Improve the ACPI handling of interrupt GPIOs (Christophe Ricard). - Fix the handling of the list of device IDs of device objects found in the ACPI namespace and add a helper for checking if there is a device object for a given device ID (Lukas Wunner). - Change the logic in the ACPI namespace scanning code to create struct acpi_device objects for all ACPI device objects found in the namespace even if _STA fails for them which helps to avoid device enumeration problems on Microsoft Surface 3 (Aaron Lu). - Add support for the APM X-Gene ACPI I2C device to the ACPI driver for AMD SoCs (Loc Ho). - Fix the long-standing issue with the DMA controller on Intel SoCs where ACPI tables have no power management support for the DMA controller itself, but it can be powered off automatically when the last (other) device on the SoC is powered off via ACPI and clean up the ACPI driver for Intel SoCs (acpi-lpss) after previous attempts to fix that problem (Andy Shevchenko). - Assorted ACPI fixes and cleanups (Andy Lutomirski, Colin Ian King, Javier Martinez Canillas, Ken Xue, Mathias Krause, Rafael Wysocki, Sinan Kaya). - Update the device properties framework for better handling of built-in properties, add support for built-in properties to the platform bus type, update the MFD subsystem's handling of device properties and add support for passing default configuration data as device properties to the intel-lpss MFD drivers, convert the designware I2C driver to use the unified device properties API and add a fallback mechanism for using default built-in properties if the platform firmware fails to provide the properties as expected by drivers (Andy Shevchenko, Mika Westerberg, Heikki Krogerus, Andrew Morton). - Add new Device Tree bindings to the Operating Performance Points (OPP) framework and update the exynos4412 DT binding accordingly, introduce debugfs support for the OPP framework (Viresh Kumar, Bartlomiej Zolnierkiewicz). - Migrate the mt8173 cpufreq driver to the new OPP bindings (Pi-Cheng Chen). - Update the cpufreq core to make the handling of governors more efficient, especially on systems where policy objects are shared between multiple CPUs (Viresh Kumar, Rafael Wysocki). - Fix cpufreq governor handling on configurations with CONFIG_HZ_PERIODIC set (Chen Yu). - Clean up the cpufreq core code related to the boost sysfs knob support and update the ACPI cpufreq driver accordingly (Rafael Wysocki). - Add a new cpufreq driver for ST platforms and corresponding Device Tree bindings (Lee Jones). - Update the intel_pstate driver to allow the P-state selection algorithm used by it to depend on the CPU ID of the processor it is running on, make it use a special P-state selection algorithm (with an IO wait time compensation tweak) on Atom CPUs based on the Airmont and Silvermont cores so as to reduce their energy consumption and improve intel_pstate documentation (Philippe Longepe, Srinivas Pandruvada). - Update the cpufreq-dt driver to support registering cooling devices that use the (P * V^2 * f) dynamic power draw formula where V is the voltage, f is the frequency and P is a constant coefficient provided by Device Tree and update the arm_big_little cpufreq driver to use that support (Punit Agrawal). - Assorted cpufreq driver (cpufreq-dt, qoriq, pcc-cpufreq, blackfin-cpufreq) updates (Andrzej Hajda, Hongtao Jia, Jacob Tanenbaum, Markus Elfring). - cpuidle core tweaks related to polling and measured_us calculation (Rik van Riel). - Removal of modularity from a few cpuidle drivers (clps711x, ux500, exynos) that cannot be built as modules in practice (Paul Gortmaker). - PM core update to prevent devices from being probed during system suspend/resume which is generally problematic and may lead to inconsistent behavior (Grygorii Strashko). - Assorted updates of the PM core and related code (Julia Lawall, Manuel Pégourié-Gonnard, Maruthi Bayyavarapu, Rafael Wysocki, Ulf Hansson). - PNP bus type updates (Christophe Le Roy, Heiner Kallweit). - PCI PM code cleanups (Jarkko Nikula, Julia Lawall). - cpupower tool updates (Jacob Tanenbaum, Thomas Renninger)" * tag 'pm+acpi-4.5-rc1-1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (177 commits) PM / clk: don't leave clocks enabled when driver not bound i2c: dw: Add APM X-Gene ACPI I2C device support ACPI / APD: Add APM X-Gene ACPI I2C device support ACPI / LPSS: change 'does not have' to 'has' in comment Revert "dmaengine: dw: platform: provide platform data for Intel" dmaengine: dw: return immediately from IRQ when DMA isn't in use dmaengine: dw: platform: power on device on shutdown ACPI / LPSS: override power state for LPSS DMA device PM / OPP: Use snprintf() instead of sprintf() Documentation: cpufreq: intel_pstate: enhance documentation ACPI, PCI, irq: remove redundant check for null string pointer ACPI / video: driver must be registered before checking for keypresses cpufreq-dt: fix handling regulator_get_voltage() result cpufreq: governor: Fix negative idle_time when configured with CONFIG_HZ_PERIODIC PM / sleep: Add support for read-only sysfs attributes ACPI: Fix white space in a structure definition ACPI / SBS: fix inconsistent indenting inside if statement PNP: respect PNP_DRIVER_RES_DO_NOT_CHANGE when detaching ACPI / PNP: constify device IDs ACPI / PCI: Simplify acpi_penalize_isa_irq() ... | 13 January 2016, 04:25:09 UTC |
