git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next Jonathan writes: First round of IIO new device support, features and cleanups for the 4.7 cycle. New core support * UV light modifier (for intensity) * UV light index channel type. New device support * hp206c barometer and altimeter - new driver. * mcp4131 potentiometer - new driver supporting lots of parts from Microchip. * mma8452 - FXLS8471Q support - NXP LPC18XX SOC ADC - new driver. - NXP LPC18XX SOC DAC - new driver. - rockchip_saradc - support rk3399 * st accel - h3lis331dl support Staging driver removals * adis16204 - obsolete part making it hard to get parts to test the driver in order to clean it up. * adis16220 - obsolete part making it hard to get the parts test the driver in order to clean it up. Features * core - convenience functions to claim / release direct access to the device. Makes more consistent handling of this corner easier. Used in ad7192 driver. * ak8975 - power regulator support. * at91-sama5d2 - differential channel support. * mma8452 - runtime pm support - drop device specific autosleep and use the runtime pm one instead. * ms5611 - DT bindings - oversampling ratio support Cleanups and minor fixes * MAINTAINERS - Peter got married - hence name change! * Documentation - Fix a typo in in_proximity_raw description. - Add some missing docs for iio_buffer_access_funcs. * Tools - update iio_event_monitor names to match new stuff. - make generic_buffer look for triggers ending in -trigger as we let these in for a number of drivers a long time back and now it is a fairly common option. Drivers * staging wide - convert bare unsigned usage to unsigned int to comply with coding style. * non staging wide: - since boiler plate gpio handling of interrupts has been moved into the ACPI core we don't need to include gpio/consumer.h in a load of drivers so drop it. * ad7606 - fix an endian casting sparse warning. * ak8975 - fix a possible unitialized warning from gcc. - drop and unused field left over from earlier cleanups - fix a missing regulator_disable on exit. * at91-sama5d2 - typo and indentation - missing IOMEM dependency. - cleanup mode register usage by avoidling erasing whole thing when changing the sampling frequency. * bmc150 - use the core demux and available_scan_masks to simplify buffer handling - optimize the transfers in the trigger handler now we have a magic function to emulate bulk reads (under circumstances met here). This matters with some rather dumb i2c adapters in particular. - use a single regmap_conf for all bus types as they were all the same. * bmg160 - use the core demux and available_scan_masks to simplify the buffer handling - optimize the transfers in the trigger handler now we have a magic funciton to emulate bulk rads (under circumstances met here). - drop gpio interrupt probing from the driver (ACPI) as now handled by the ACPI core. * ina2xx-adc - update the CALIB register when RShunt changes. - fix scale for VShunt - in reality this error canceled out when used. * isl29028 - use regmap to retrieve the struct device instead of carrying a second copy of it around. * kxcjk-1013 - use core demux - optimize i2c transfers in the trigger handler. * mcp4531 - refactor to use a pointer to access model parameters instead of indexing into the array each time. * mma8452 - style fixes - avoid swtiching to active whenever the config changes - add missin i2c_device_id for mma8451 * mpu6050 - fix possible NULL dereference. - fix the name / chip_id used when ACPI used (otherwise reports as NULL). * ms5611 - fix a missing regulator_disable that left the regulator on during removal. * mxc4005 - drop gpio interrupt handling for ACPI case from driver as the core now handles this case. * st-sensors - note that there are only ever a maximum of 3 axis on current st-sensors so just allocate a fixed sized buffer big enough for that. * tpl0102 - change the i2c_check_functionality condition to bring it inline with other IIO users as EOPNOTSUPP. * tsl2563 - replace deprecated flush_scheduled_work

2016-04-01Elf: add livepatch-specific Elf constantsJessica Yu1-4/+6
Livepatch manages its own relocation sections and symbols in order to be able to reuse module loader code to write relocations. This removes livepatch's dependence on separate "dynrela" sections to write relocations and also allows livepatch to patch modules that are not yet loaded. The livepatch Elf relocation section flag (SHF_RELA_LIVEPATCH), and symbol section index (SHN_LIVEPATCH) allow both livepatch and the module loader to identity livepatch relocation sections and livepatch symbols. Livepatch relocation sections are marked with SHF_RELA_LIVEPATCH to indicate to the module loader that it should not apply that relocation section and that livepatch will handle them. The SHN_LIVEPATCH shndx marks symbols that will be resolved by livepatch. The module loader ignores these symbols and does not attempt to resolve them. The values of these Elf constants were selected from OS-specific ranges according to the definitions from glibc.

2016-03-31drm: Add an encoder and connector type enum for DPI.Eric Anholt1-0/+2
Right now exynos is exposing DPI as a TMDS encoder and VGA connector, which seems rather misleading. This isn't just an internal detail, since xrandr actually exposes "VGA" as the output name. Define some new enums so that vc4's DPI can have a more informative name. I considered other names for the connector as well. For VC4, the Adafruit DPI kippah takes the 28 GPIO pins and routes them to a standard-ish 40-pin FPC connector, but "40-pin FPC" doesn't uniquely identify an ordering of pins (apparently some other orderings exist), doesn't explain things as well for the user (who, if anything, knows their product is a DPI kippah/panel combo), and actually doesn't have to exist (one could connect the 28 GPIOs directly to something else). Simply "DPI" seems like a good compromise name to distinguish from the HDMI, DSI, and TV connectors . Signed-off-by: Eric Anholt <[email protected]> Reviewed-by: Daniel Vetter <[email protected]>
2016-03-31perf/ring_buffer: Introduce new ioctl options to pause and resume the ↵Wang Nan1-0/+1
ring-buffer Add new ioctl() to pause/resume ring-buffer output. In some situations we want to read from the ring-buffer only when we ensure nothing can write to the ring-buffer during reading. Without this patch we have to turn off all events attached to this ring-buffer to achieve this. This patch is a prerequisite to enable overwrite support for the perf ring-buffer support. Following commits will introduce new methods support reading from overwrite ring buffer. Before reading, caller must ensure the ring buffer is frozen, or the reading is unreliable.

Make the 2 byte padding in struct bpf_tunnel_key between tunnel_ttl and tunnel_label members explicit. No issue has been observed, and gcc/llvm does padding for the old struct already, where tunnel_label was not yet present, so the current code works, but since it's part of uapi, make sure we don't introduce holes in structs. Therefore, add tunnel_ext that we can use generically in future (f.e. to flag OAM messages for backends, etc). Also add the offset to the compat tests to be sure should some compilers not padd the tail of the old version of bpf_tunnel_key.

2016-03-29ASoC: topology: ABI - Define types for vendor tuplesMengdong Lin1-1/+41
Tuples, a pair of token and value, can be used to define vendor specific data, for controls and widgets. This can avoid importing binary data blob from other files. Vendor specific tuple arrays will be embeded in the private data buffer of a control or widget object. To be backward compatible, union is used to define the tuple arrays in the existing private data ABI object 'struct snd_soc_tplg_private'. Vendors need to make sure the token values defined by the topology conf file match those defined by their driver. Now supported tuple types are uuid, string, bool, byte, short and word.

git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma Pull more rdma updates from Doug Ledford: "Round two of 4.6 merge window patches. This is a monster pull request. I held off on the hfi1 driver updates (the hfi1 driver is intimately tied to the qib driver and the new rdmavt software library that was created to help both of them) in my first pull request. The hfi1/qib/rdmavt update is probably 90% of this pull request. The hfi1 driver is being left in staging so that it can be fixed up in regards to the API that Al and yourself didn't like. Intel has agreed to do the work, but in the meantime, this clears out 300+ patches in the backlog queue and brings my tree and their tree closer to sync. This also includes about 10 patches to the core and a few to mlx5 to create an infrastructure for configuring SRIOV ports on IB devices. That series includes one patch to the net core that we sent to netdev@ and Dave Miller with each of the three revisions to the series. We didn't get any response to the patch, so we took that as implicit approval. Finally, this series includes Intel's new iWARP driver for their x722 cards. It's not nearly the beast as the hfi1 driver. It also has a linux-next merge issue, but that has been resolved and it now passes just fine. Summary: - A few minor core fixups needed for the next patch series - The IB SRIOV series. This has bounced around for several versions. Of note is the fact that the first patch in this series effects the net core. It was directed to netdev and DaveM for each iteration of the series (three versions total). Dave did not object, but did not respond either. I've taken this as permission to move forward with the series. - The new Intel X722 iWARP driver - A huge set of updates to the Intel hfi1 driver. Of particular interest here is that we have left the driver in staging since it still has an API that people object to.

2016-03-22kernel: add kcov code coverageDmitry Vyukov1-0/+10
kcov provides code coverage collection for coverage-guided fuzzing (randomized testing). Coverage-guided fuzzing is a testing technique that uses coverage feedback to determine new interesting inputs to a system. A notable user-space example is AFL (http://lcamtuf.coredump.cx/afl/). However, this technique is not widely used for kernel testing due to missing compiler and kernel support. kcov does not aim to collect as much coverage as possible. It aims to collect more or less stable coverage that is function of syscall inputs. To achieve this goal it does not collect coverage in soft/hard interrupts and instrumentation of some inherently non-deterministic or non-interesting parts of kernel is disbled (e.g. scheduler, locking). Currently there is a single coverage collection mode (tracing), but the API anticipates additional collection modes. Initially I also implemented a second mode which exposes coverage in a fixed-size hash table of counters (what Quentin used in his original patch). I've dropped the second mode for simplicity. This patch adds the necessary support on kernel side. The complimentary compiler support was added in gcc revision 231296. We've used this support to build syzkaller system call fuzzer, which has found 90 kernel bugs in just 2 months: https://github.com/google/syzkaller/wiki/Found-Bugs We've also found 30+ bugs in our internal systems with syzkaller. Another (yet unexplored) direction where kcov coverage would greatly help is more traditional "blob mutation". For example, mounting a random blob as a filesystem, or receiving a random blob over wire. Why not gcov. Typical fuzzing loop looks as follows: (1) reset coverage, (2) execute a bit of code, (3) collect coverage, repeat. A typical coverage can be just a dozen of basic blocks (e.g. an invalid input). In such context gcov becomes prohibitively expensive as reset/collect coverage steps depend on total number of basic blocks/edges in program (in case of kernel it is about 2M). Cost of kcov depends only on number of executed basic blocks/edges. On top of that, kernel requires per-thread coverage because there are always background threads and unrelated processes that also produce coverage. With inlined gcov instrumentation per-thread coverage is not possible. kcov exposes kernel PCs and control flow to user-space which is insecure. But debugfs should not be mapped as user accessible.

git://git.kernel.org/pub/scm/linux/kernel/git/dgc/linux-xfs Pull xfs updates from Dave Chinner: "There's quite a lot in this request, and there's some cross-over with ext4, dax and quota code due to the nature of the changes being made. As for the rest of the XFS changes, there are lots of little things all over the place, which add up to a lot of changes in the end. The major changes are that we've reduced the size of the struct xfs_inode by ~100 bytes (gives an inode cache footprint reduction of >10%), the writepage code now only does a single set of mapping tree lockups so uses less CPU, delayed allocation reservations won't overrun under random write loads anymore, and we added compile time verification for on-disk structure sizes so we find out when a commit or platform/compiler change breaks the on disk structure as early as possible. Change summary: - error propagation for direct IO failures fixes for both XFS and ext4 - new quota interfaces and XFS implementation for iterating all the quota IDs in the filesystem - locking fixes for real-time device extent allocation - reduction of duplicate information in the xfs and vfs inode, saving roughly 100 bytes of memory per cached inode. - buffer flag cleanup - rework of the writepage code to use the generic write clustering mechanisms - several fixes for inode flag based DAX enablement - rework of remount option parsing - compile time verification of on-disk format structure sizes - delayed allocation reservation overrun fixes - lots of little error handling fixes - small memory leak fixes - enable xfsaild freezing again" * tag 'xfs-for-linus-4.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/dgc/linux-xfs: (66 commits) xfs: always set rvalp in xfs_dir2_node_trim_free xfs: ensure committed is initialized in xfs_trans_roll xfs: borrow indirect blocks from freed extent when available xfs: refactor delalloc indlen reservation split into helper xfs: update freeblocks counter after extent deletion xfs: debug mode forced buffered write failure xfs: remove impossible condition xfs: check sizes of XFS on-disk structures at compile time xfs: ioends require logically contiguous file offsets xfs: use named array initializers for log item dumping xfs: fix computation of inode btree maxlevels xfs: reinitialise per-AG structures if geometry changes during recovery xfs: remove xfs_trans_get_block_res xfs: fix up inode32/64 (re)mount handling xfs: fix format specifier , should be %llx and not %llu xfs: sanitize remount options xfs: convert mount option parsing to tokens xfs: fix two memory leaks in xfs_attr_list.c error paths xfs: XFS_DIFLAG2_DAX limited by PAGE_SIZE xfs: dynamically switch modes when XFS_DIFLAG2_DAX is set/cleared ...

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull x86 protection key support from Ingo Molnar: "This tree adds support for a new memory protection hardware feature that is available in upcoming Intel CPUs: 'protection keys' (pkeys). There's a background article at LWN.net: https://lwn.net/Articles/643797/ The gist is that protection keys allow the encoding of user-controllable permission masks in the pte. So instead of having a fixed protection mask in the pte (which needs a system call to change and works on a per page basis), the user can map a (handful of) protection mask variants and can change the masks runtime relatively cheaply, without having to change every single page in the affected virtual memory range. This allows the dynamic switching of the protection bits of large amounts of virtual memory, via user-space instructions. It also allows more precise control of MMU permission bits: for example the executable bit is separate from the read bit (see more about that below). This tree adds the MM infrastructure and low level x86 glue needed for that, plus it adds a high level API to make use of protection keys - if a user-space application calls: mmap(..., PROT_EXEC); or mprotect(ptr, sz, PROT_EXEC); (note PROT_EXEC-only, without PROT_READ/WRITE), the kernel will notice this special case, and will set a special protection key on this memory range. It also sets the appropriate bits in the Protection Keys User Rights (PKRU) register so that the memory becomes unreadable and unwritable. So using protection keys the kernel is able to implement 'true' PROT_EXEC on x86 CPUs: without protection keys PROT_EXEC implies PROT_READ as well. Unreadable executable mappings have security advantages: they cannot be read via information leaks to figure out ASLR details, nor can they be scanned for ROP gadgets - and they cannot be used by exploits for data purposes either. We know about no user-space code that relies on pure PROT_EXEC mappings today, but binary loaders could start making use of this new feature to map binaries and libraries in a more secure fashion. There is other pending pkeys work that offers more high level system call APIs to manage protection keys - but those are not part of this pull request. Right now there's a Kconfig that controls this feature (CONFIG_X86_INTEL_MEMORY_PROTECTION_KEYS) that is default enabled (like most x86 CPU feature enablement code that has no runtime overhead), but it's not user-configurable at the moment. If there's any serious problem with this then we can make it configurable and/or flip the default" * 'mm-pkeys-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (38 commits) x86/mm/pkeys: Fix mismerge of protection keys CPUID bits mm/pkeys: Fix siginfo ABI breakage caused by new u64 field x86/mm/pkeys: Fix access_error() denial of writes to write-only VMA mm/core, x86/mm/pkeys: Add execute-only protection keys support x86/mm/pkeys: Create an x86 arch_calc_vm_prot_bits() for VMA flags x86/mm/pkeys: Allow kernel to modify user pkey rights register x86/fpu: Allow setting of XSAVE state x86/mm: Factor out LDT init from context init mm/core, x86/mm/pkeys: Add arch_validate_pkey() mm/core, arch, powerpc: Pass a protection key in to calc_vm_flag_bits() x86/mm/pkeys: Actually enable Memory Protection Keys in the CPU x86/mm/pkeys: Add Kconfig prompt to existing config option x86/mm/pkeys: Dump pkey from VMA in /proc/pid/smaps x86/mm/pkeys: Dump PKRU with other kernel registers mm/core, x86/mm/pkeys: Differentiate instruction fetches x86/mm/pkeys: Optimize fault handling in access_error() mm/core: Do not enforce PKEY permissions on remote mm access um, pkeys: Add UML arch_*_access_permitted() methods mm/gup, x86/mm/pkeys: Check VMAs and PTEs for protection keys x86/mm/gup: Simplify get_user_pages() PTE bit handling ...

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio Pull GPIO updates from Linus Walleij: "This is the bulk of GPIO changes for kernel v4.6. There is quite a lot of interesting stuff going on. The patches to other subsystems and arch-wide are ACKed as far as possible, though I consider things like per-arch <asm/gpio.h> as essentially a part of the GPIO subsystem so it should not be needed. Core changes: - The gpio_chip is now a *real device*. Until now the gpio chips were just piggybacking the parent device or (gasp) floating in space outside of the device model. We now finally make GPIO chips devices. The gpio_chip will create a gpio_device which contains a struct device, and this gpio_device struct is kept private. Anything that needs to be kept private from the rest of the kernel will gradually be moved over to the gpio_device. - As a result of making the gpio_device a real device, we have added resource management, so devm_gpiochip_add_data() will cut down on overhead and reduce code lines. A huge slew of patches convert almost all drivers in the subsystem to use this. - Building on making the GPIO a real device, we add the first step of a new userspace ABI: the GPIO character device. We take small steps here, so we first add a pure *information* ABI and the tool "lsgpio" that will list all GPIO devices on the system and all lines on these devices. We can now discover GPIOs properly from userspace. We still have not come up with a way to actually *use* GPIOs from userspace. - To encourage people to use the character device for the future, we have it always-enabled when using GPIO. The old sysfs ABI is still opt-in (and can be used in parallel), but is marked as deprecated. We will keep it around for the foreseeable future, but it will not be extended to cover ever more use cases. Cleanup: - Bjorn Helgaas removed a whole slew of per-architecture <asm/gpio.h> includes. This dates back to when GPIO was an opt-in feature and no shared library even existed: just a header file with proper prototypes was provided and all semantics were up to the arch to implement. These patches make the GPIO chip even more a proper device and cleans out leftovers of the old in-kernel API here and there. Still some cruft is left but it's very little now. - There is still some clamping of return values for .get() going on, but we now return sane values in the vast majority of drivers and the errorpath is sanitized. Some patches for powerpc, blackfin and unicore still drop in. - We continue to switch the ARM, MIPS, blackfin, m68k local GPIO implementations to use gpiochip_add_data() and cut down on code lines. - MPC8xxx is converted to use the generic GPIO helpers. - ATH79 is converted to use the generic GPIO helpers. New drivers: - WinSystems WS16C48 - Acces 104-DIO-48E - F81866 (a F7188x variant) - Qoric (a MPC8xxx variant) - TS-4800 - SPI serializers (pisosr): simple 74xx shift registers connected to SPI to obtain a dirt-cheap output-only GPIO expander. - Texas Instruments TPIC2810 - Texas Instruments TPS65218 - Texas Instruments TPS65912 - X-Gene (ARM64) standby GPIO controller" * tag 'gpio-v4.6-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (194 commits) Revert "Share upstreaming patches" gpio: mcp23s08: Fix clearing of interrupt. gpiolib: Fix comment referring to gpio_*() in gpiod_*() gpio: pca953x: Fix pca953x_gpio_set_multiple() on 64-bit gpio: xgene: Fix kconfig for standby GIPO contoller gpio: Add generic serializer DT binding gpio: uapi: use 0xB4 as ioctl() major gpio: tps65912: fix bad merge Revert "gpio: lp3943: Drop pin_used and lp3943_gpio_request/lp3943_gpio_free" gpio: omap: drop dev field from gpio_bank structure gpio: mpc8xxx: Slightly update the code for better readability gpio: mpc8xxx: Remove *read_reg and *write_reg from struct mpc8xxx_gpio_chip gpio: mpc8xxx: Fixup setting gpio direction output gpio: mcp23s08: Add support for mcp23s18 dt-bindings: gpio: altera: Fix altr,interrupt-type property gpio: add driver for MEN 16Z127 GPIO controller gpio: lp3943: Drop pin_used and lp3943_gpio_request/lp3943_gpio_free gpio: timberdale: Switch to devm_ioremap_resource() gpio: ts4800: Add IMX51 dependency gpiolib: rewrite gpiodev_add_to_list ...
