2018-01-31Merge branch 'misc.poll' of ↵Linus Torvalds221-432/+430
git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs Pull poll annotations from Al Viro: "This introduces a __bitwise type for POLL### bitmap, and propagates the annotations through the tree. Most of that stuff is as simple as 'make ->poll() instances return __poll_t and do the same to local variables used to hold the future return value'. Some of the obvious brainos found in process are fixed (e.g. POLLIN misspelled as POLL_IN). At that point the amount of sparse warnings is low and most of them are for genuine bugs - e.g. ->poll() instance deciding to return -EINVAL instead of a bitmap. I hadn't touched those in this series - it's large enough as it is. Another problem it has caught was eventpoll() ABI mess; select.c and eventpoll.c assumed that corresponding POLL### and EPOLL### were equal. That's true for some, but not all of them - EPOLL### are arch-independent, but POLL### are not. The last commit in this series separates userland POLL### values from the (now arch-independent) kernel-side ones, converting between them in the few places where they are copied to/from userland. AFAICS, this is the least disruptive fix preserving poll(2) ABI and making epoll() work on all architectures. As it is, it's simply broken on sparc - try to give it EPOLLWRNORM and it will trigger only on what would've triggered EPOLLWRBAND on other architectures. EPOLLWRBAND and EPOLLRDHUP, OTOH, are never triggered at all on sparc. With this patch they should work consistently on all architectures" * 'misc.poll' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: (37 commits) make kernel-side POLL... arch-independent eventpoll: no need to mask the result of epi_item_poll() again eventpoll: constify struct epoll_event pointers debugging printk in sg_poll() uses %x to print POLL... bitmap annotate poll(2) guts 9p: untangle ->poll() mess ->si_band gets POLL... bitmap stored into a user-visible long field ring_buffer_poll_wait() return value used as return value of ->poll() the rest of drivers/*: annotate ->poll() instances media: annotate ->poll() instances fs: annotate ->poll() instances ipc, kernel, mm: annotate ->poll() instances net: annotate ->poll() instances apparmor: annotate ->poll() instances tomoyo: annotate ->poll() instances sound: annotate ->poll() instances acpi: annotate ->poll() instances crypto: annotate ->poll() instances block: annotate ->poll() instances x86: annotate ->poll() instances ...

2018-01-31Merge branch 'siginfo-linus' of ↵Linus Torvalds4-5/+5
git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace Pull siginfo cleanups from Eric Biederman: "Long ago when 2.4 was just a testing release copy_siginfo_to_user was made to copy individual fields to userspace, possibly for efficiency and to ensure initialized values were not copied to userspace. Unfortunately the design was complex, it's assumptions unstated, and humans are fallible and so while it worked much of the time that design failed to ensure unitialized memory is not copied to userspace. This set of changes is part of a new design to clean up siginfo and simplify things, and hopefully make the siginfo handling robust enough that a simple inspection of the code can be made to ensure we don't copy any unitializied fields to userspace. The design is to unify struct siginfo and struct compat_siginfo into a single definition that is shared between all architectures so that anyone adding to the set of information shared with struct siginfo can see the whole picture. Hopefully ensuring all future si_code assignments are arch independent. The design is to unify copy_siginfo_to_user32 and copy_siginfo_from_user32 so that those function are complete and cope with all of the different cases documented in signinfo_layout. I don't think there was a single implementation of either of those functions that was complete and correct before my changes unified them. The design is to introduce a series of helpers including force_siginfo_fault that take the values that are needed in struct siginfo and build the siginfo structure for their callers. Ensuring struct siginfo is built correctly. The remaining work for 4.17 (unless someone thinks it is post -rc1 material) is to push usage of those helpers down into the architectures so that architecture specific code will not need to deal with the fiddly work of intializing struct siginfo, and then when struct siginfo is guaranteed to be fully initialized change copy siginfo_to_user into a simple wrapper around copy_to_user. Further there is work in progress on the issues that have been documented requires arch specific knowledge to sort out. The changes below fix or at least document all of the issues that have been found with siginfo generation. Then proceed to unify struct siginfo the 32 bit helpers that copy siginfo to and from userspace, and generally clean up anything that is not arch specific with regards to siginfo generation. It is a lot but with the unification you can of siginfo you can already see the code reduction in the kernel" * 'siginfo-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: (45 commits) signal/memory-failure: Use force_sig_mceerr and send_sig_mceerr mm/memory_failure: Remove unused trapno from memory_failure signal/ptrace: Add force_sig_ptrace_errno_trap and use it where needed signal/powerpc: Remove unnecessary signal_code parameter of do_send_trap signal: Helpers for faults with specialized siginfo layouts signal: Add send_sig_fault and force_sig_fault signal: Replace memset(info,...) with clear_siginfo for clarity signal: Don't use structure initializers for struct siginfo signal/arm64: Better isolate the COMPAT_TASK portion of ptrace_hbptriggered ptrace: Use copy_siginfo in setsiginfo and getsiginfo signal: Unify and correct copy_siginfo_to_user32 signal: Remove the code to clear siginfo before calling copy_siginfo_from_user32 signal: Unify and correct copy_siginfo_from_user32 signal/blackfin: Remove pointless UID16_SIGINFO_COMPAT_NEEDED signal/blackfin: Move the blackfin specific si_codes to asm-generic/siginfo.h signal/tile: Move the tile specific si_codes to asm-generic/siginfo.h signal/frv: Move the frv specific si_codes to asm-generic/siginfo.h signal/ia64: Move the ia64 specific si_codes to asm-generic/siginfo.h signal/powerpc: Remove redefinition of NSIGTRAP on powerpc signal: Move addr_lsb into the _sigfault union for clarity ...

git://git.kernel.org/pub/scm/linux/kernel/git/jlayton/linux Pull inode->i_version rework from Jeff Layton: "This pile of patches is a rework of the inode->i_version field. We have traditionally incremented that field on every inode data or metadata change. Typically this increment needs to be logged on disk even when nothing else has changed, which is rather expensive. It turns out though that none of the consumers of that field actually require this behavior. The only real requirement for all of them is that it be different iff the inode has changed since the last time the field was checked. Given that, we can optimize away most of the i_version increments and avoid dirtying inode metadata when the only change is to the i_version and no one is querying it. Queries of the i_version field are rather rare, so we can help write performance under many common workloads. This patch series converts existing accesses of the i_version field to a new API, and then converts all of the in-kernel filesystems to use it. The last patch in the series then converts the backend implementation to a scheme that optimizes away a large portion of the metadata updates when no one is looking at it. In my own testing this series significantly helps performance with small I/O sizes. I also got this email for Christmas this year from the kernel test robot (a 244% r/w bandwidth improvement with XFS over DAX, with 4k writes): https://lkml.org/lkml/2017/12/25/8 A few of the earlier patches in this pile are also flowing to you via other trees (mm, integrity, and nfsd trees in particular)". * tag 'iversion-v4.16-1' of git://git.kernel.org/pub/scm/linux/kernel/git/jlayton/linux: (22 commits) fs: handle inode->i_version more efficiently btrfs: only dirty the inode in btrfs_update_time if something was changed xfs: avoid setting XFS_ILOG_CORE if i_version doesn't need incrementing fs: only set S_VERSION when updating times if necessary IMA: switch IMA over to new i_version API xfs: convert to new i_version API ufs: use new i_version API ocfs2: convert to new i_version API nfsd: convert to new i_version API nfs: convert to new i_version API ext4: convert to new i_version API ext2: convert to new i_version API exofs: switch to new i_version API btrfs: convert to new i_version API afs: convert to new i_version API affs: convert to new i_version API fat: convert to new i_version API fs: don't take the i_lock in inode_inc_iversion fs: new API for handling inode->i_version ntfs: remove i_version handling ...

Pull MMC updates from Ulf Hansson: "There are two major achievements for MMC in this release, which deserves to be specially highlighted. First, we have converted the MMC block device from using the legacy blk interface into using the modern blkmq interface. Not only do we get all the nice effects from using blkmq, but it also means that new fresh nice code replaces old rusty code. Great news to everybody that cares about MMC/SD! It should also be noted that converting to blkmq has not been trivial, mostly because of that we have been carrying too much of MMC specific optimizations for the I/O request path, rather than striving to move these to the generic blk layer. Hopefully we won't be doing that mistake, ever again. Special thanks to Adrian Hunter (Intel) and to Linus Walleij (Linaro), who both have been working on this for quite some time! Second, on top of the blkmq deployment, we have enabled full support the eMMC command queuing feature, introduced in the eMMC v.5.1 spec. This also includes an implementation of a host driver library, supporting the corresponding CQHCI HW. Ideally, those controllers that supports CQHCI should only need some minor adaptations to make this play. So far the sdhci-pci driver for the Intel GLKs and the sdhci-of-arasan driver used on Rockchip RK3399, have enabled support for eMMC command queueing. Worth to highlight is also that, implementing the eMMC command queuing support has been a collaborative effort, as several people from Codeaurora, Rockchip, Intel and Linaro have been involved. However, the work has been driven by Adrian Hunter (Intel). In some shadow of the above, here are the rest of the highlights: MMC core: - Don't remove non-removable cards during system suspend - Add a slot-gpio helper to check capability of GPIO WP detection MMC host: - sdhci: Cleanups and improvements of some wakeup related code - sdhci-pci-arasan: New variant to support Arasan PCI HW with integrated phy - sdhci-acpi: Avoid broken UHS transfer modes on Intel CHT - sdhci-acpi: Add support for ACPI HID of AMD Controller with HS400 - sdhci_f_sdh30: Add ACPI support - sdhci-esdhc-imx: Enable/disable clock at runtime suspend/resume - sdhci-of-esdhc: A few minor fixes - mmci: Add support for new STM32 variant - renesas_sdhi: enable R-Car D3 (r8a77995) support - tmio/renesas_sdhi: Re-structuring, cleanups and modernizations" * tag 'mmc-v4.16' of git://git.kernel.org/pub/scm/linux/kernel/git/ulfh/mmc: (96 commits) mmc: mmci: fix error return code in mmci_probe() mmc: davinci: suppress error message on EPROBE_DEFER mmc: davinci: dont' use module_platform_driver_probe() mmc: tmio: hide unused tmio_mmc_clk_disable/tmio_mmc_clk_enable functions mmc: mmci: Add STM32 variant mmc: mmci: Add support for setting pad type via pinctrl mmc: mmci: Don't pretend all variants to have OPENDRAIN bit mmc: mmci: Don't pretend all variants to have MCI_STARBITERR flag mmc: mmci: Don't pretend all variants to have MMCIMASK1 register mmc: tmio: refactor .get_ro hook mmc: slot-gpio: add a helper to check capability of GPIO WP detection mmc: tmio: remove dma_ops from tmio_mmc_host_probe() argument mmc: tmio: move {tmio_}mmc_of_parse() to tmio_mmc_host_alloc() mmc: tmio: move clk_enable/disable out of tmio_mmc_host_probe() mmc: tmio: ioremap memory resource in tmio_mmc_host_alloc() mmc: sh_mmcif: remove redundant initialization of 'opc' mmc: sdhci: Rework sdhci_enable_irq_wakeups() mmc: sdhci: Handle failure of enable_irq_wake() mmc: sdhci: Stop exporting sdhci_enable_irq_wakeups() mmc: sdhci-pci: Use device wakeup capability to determine MMC_PM_WAKE_SDIO_IRQ capability ...

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull power management updates from Rafael Wysocki: "This includes some infrastructure changes in the PM core, mostly related to integration between runtime PM and system-wide suspend and hibernation, plus some driver changes depending on them and fixes for issues in that area which have become quite apparent recently. Also included are changes making more x86-based systems use the Low Power Sleep S0 _DSM interface by default, which turned out to be necessary to handle power button wakeups from suspend-to-idle on Surface Pro3. On the cpufreq front we have fixes and cleanups in the core, some new hardware support, driver updates and the removal of some unused code from the CPU cooling thermal driver. Apart from this, the Operating Performance Points (OPP) framework is prepared to be used with power domains in the future and there is a usual bunch of assorted fixes and cleanups. Specifics: - Define a PM driver flag allowing drivers to request that their devices be left in suspend after system-wide transitions to the working state if possible and add support for it to the PCI bus type and the ACPI PM domain (Rafael Wysocki). - Make the PM core carry out optimizations for devices with driver PM flags set in some cases and make a few drivers set those flags (Rafael Wysocki). - Fix and clean up wrapper routines allowing runtime PM device callbacks to be re-used for system-wide PM, change the generic power domains (genpd) framework to stop using those routines incorrectly and fix up a driver depending on that behavior of genpd (Rafael Wysocki, Ulf Hansson, Geert Uytterhoeven). - Fix and clean up the PM core's device wakeup framework and re-factor system-wide PM core code related to device wakeup (Rafael Wysocki, Ulf Hansson, Brian Norris). - Make more x86-based systems use the Low Power Sleep S0 _DSM interface by default (to fix power button wakeup from suspend-to-idle on Surface Pro3) and add a kernel command line switch to tell it to ignore the system sleep blacklist in the ACPI core (Rafael Wysocki). - Fix a race condition related to cpufreq governor module removal and clean up the governor management code in the cpufreq core (Rafael Wysocki). - Drop the unused generic code related to the handling of the static power energy usage model in the CPU cooling thermal driver along with the corresponding documentation (Viresh Kumar). - Add mt2712 support to the Mediatek cpufreq driver (Andrew-sh Cheng). - Add a new operating point to the imx6ul and imx6q cpufreq drivers and switch the latter to using clk_bulk_get() (Anson Huang, Dong Aisheng). - Add support for multiple regulators to the TI cpufreq driver along with a new DT binding related to that and clean up that driver somewhat (Dave Gerlach). - Fix a powernv cpufreq driver regression leading to incorrect CPU frequency reporting, fix that driver to deal with non-continguous P-states correctly and clean it up (Gautham Shenoy, Shilpasri Bhat). - Add support for frequency scaling on Armada 37xx SoCs through the generic DT cpufreq driver (Gregory CLEMENT). - Fix error code paths in the mvebu cpufreq driver (Gregory CLEMENT). - Fix a transition delay setting regression in the longhaul cpufreq driver (Viresh Kumar). - Add Skylake X (server) support to the intel_pstate cpufreq driver and clean up that driver somewhat (Srinivas Pandruvada). - Clean up the cpufreq statistics collection code (Viresh Kumar). - Drop cluster terminology and dependency on physical_package_id from the PSCI driver and drop dependency on arm_big_little from the SCPI cpufreq driver (Sudeep Holla). - Add support for system-wide suspend and resume to the RAPL power capping driver and drop a redundant semicolon from it (Zhen Han, Luis de Bethencourt). - Make SPI domain validation (in the SCSI SPI transport driver) and system-wide suspend mutually exclusive as they rely on the same underlying mechanism and cannot be carried out at the same time (Bart Van Assche). - Fix the computation of the amount of memory to preallocate in the hibernation core and clean up one function in there (Rainer Fiebig, Kyungsik Lee). - Prepare the Operating Performance Points (OPP) framework for being used with power domains and clean up one function in it (Viresh Kumar, Wei Yongjun). - Clean up the generic sysfs interface for device PM (Andy Shevchenko). - Fix several minor issues in power management frameworks and clean them up a bit (Arvind Yadav, Bjorn Andersson, Geert Uytterhoeven, Gustavo Silva, Julia Lawall, Luis de Bethencourt, Paul Gortmaker, Sergey Senozhatsky, gaurav jindal). -

2018-01-27hwmon: (dell-smm) Disable fan support for Dell Vostro 3360Oleksandr Natalenko1-0/+7
Calling fan related SMM functions implemented by Dell BIOS firmware on Dell Vostro 3360 freeze kernel for about 500ms. Unfortunately, it is unlikely for Dell to fix this since the machine is pretty old, so this commit just disables fan support to make the system usable again. Via "force" module param fan support can be enabled.

Pull networking fixes from David Miller: 1) The per-network-namespace loopback device, and thus its namespace, can have its teardown deferred for a long time if a kernel created TCP socket closes and the namespace is exiting meanwhile. The kernel keeps trying to finish the close sequence until it times out (which takes quite some time). Fix this by forcing the socket closed in this situation, from Dan Streetman. 2) Fix regression where we're trying to invoke the update_pmtu method on route types (in this case metadata tunnel routes) that don't implement the dst_ops method. Fix from Nicolas Dichtel. 3) Fix long standing memory corruption issues in r8169 driver by performing the chip statistics DMA programming more correctly. From Francois Romieu. 4) Handle local broadcast sends over VRF routes properly, from David Ahern. 5) Don't refire the DCCP CCID2 timer endlessly, otherwise the socket can never be released. From Alexey Kodanev. 6) Set poll flags properly in VSOCK protocol layer, from Stefan Hajnoczi. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: VSOCK: set POLLOUT | POLLWRNORM for TCP_CLOSING dccp: don't restart ccid2_hc_tx_rto_expire() if sk in closed state net: vrf: Add support for sends to local broadcast address r8169: fix memory corruption on retrieval of hardware statistics. net: don't call update_pmtu unconditionally net: tcp: close sock if net namespace is exiting

2018-01-26regulator: core: Refactor regulator_list_voltage()Maciej Purski1-5/+5
Change _regulator_list_voltage() argument from regulator to regulator_dev in order to provide better separation of core layers. Allow calling _regulator_list_voltage() from functions, with regulator_dev argument. This refactoring is needed in order to implement setting voltage of coupled regulators.

2018-01-26regulator: core: Move of_find_regulator_by_node() to of_regulator.cMaciej Purski3-22/+24
As of_find_regulator_by_node() is an of function it should be moved from core.c to of_regulator.c. It provides better separation of device tree functions from the core and allows other of_functions in of_regulator.c to resolve device_node to regulator_dev. This will be useful for implementation of parsing coupled regulators properties. Declare of_find_regulator_by_node() function in internal.h as well as regulator_class and dev_to_rdev(), as they are needed by of_find_regulator_by_node().
