git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio Pull GPIO updates from Linus Walleij: "The is the bulk of GPIO changes for the v4.16 kernel cycle. It is pretty calm this time around I think. I even got time to get to things like starting to clean up header includes. Core changes: - Disallow open drain and open source flags to be set simultaneously. This doesn't make electrical sense, and would the hardware actually respond to this setting, the result would be short circuit. - ACPI GPIO has a new core infrastructure for handling quirks. The quirks are there to deal with broken ACPI tables centrally instead of pushing the work to individual drivers. In the world of BIOS writers, the ACPI tables are perfect. Until they find a mistake in it. When such a mistake is found, we can patch it with a quirk. It should never happen, the problem is that it happens. So we accomodate for it. - Several documentation updates. - Revert the patch setting up initial direction state from reading the device. This was causing bad things for drivers that can't read status on all its pins. It is only affecting debugfs information quality. - Label descriptors with the device name if no explicit label is passed in. - Pave the ground for transitioning SPI and regulators to use GPIO descriptors by implementing some quirks in the device tree GPIO parsing code. New drivers: - New driver for the Access PCIe IDIO 24 family. Other: - Major refactorings and improvements to the GPIO mockup driver used for test and verification. - Moved the AXP209 driver over to pin control since it gained a pin control back-end. These patches will appear (with the same hashes) in the pin control pull request as well. - Convert the onewire GPIO driver w1-gpio to use descriptors. This is merged here since the W1 maintainers send very few pull requests and he ACKed it. - Start to clean up driver headers using <linux/gpio.h> to just use <linux/gpio/driver.h> as appropriate" * tag 'gpio-v4.16-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (103 commits) gpio: Timestamp events in hardirq handler gpio: Fix kernel stack leak to userspace gpio: Fix a documentation spelling mistake gpio: Documentation update gpiolib: remove redundant initialization of pointer desc gpio: of: Fix NPE from OF flags gpio: stmpe: Delete an unnecessary variable initialisation in stmpe_gpio_probe() gpio: stmpe: Move an assignment in stmpe_gpio_probe() gpio: stmpe: Improve a size determination in stmpe_gpio_probe() gpio: stmpe: Use seq_putc() in stmpe_dbg_show() gpio: No NULL owner gpio: stmpe: i2c transfer are forbiden in atomic context gpio: davinci: Include proper header gpio: da905x: Include proper header gpio: cs5535: Include proper header gpio: crystalcove: Include proper header gpio: bt8xx: Include proper header gpio: bcm-kona: Include proper header gpio: arizona: Include proper header gpio: amd8111: Include proper header ...

2018-01-31Merge branch 'siginfo-linus' of ↵Linus Torvalds3-8/+15
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/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). -

We could consolidate init_task handling instead and expand out various macros. Here's a series of patches that consolidate init_task handling: (1) Make THREAD_SIZE available to vmlinux.lds for cris, hexagon and openrisc. (2) Alter the INIT_TASK_DATA linker script macro to set init_thread_union and init_stack rather than defining these in C. Insert init_task and init_thread_into into the init_stack area in the linker script as appropriate to the configuration, with different section markers so that they end up correctly ordered. We can then get merge ia64's init_task.c into the main one. We then have a bunch of single-use INIT_*() macros that seem only to be macros because they used to be used per-arch. We can then expand these in place of the user and get rid of a few lines and a lot of backslashes. (3) Expand INIT_TASK() in place.

Alexei Starovoitov says: ==================== pull-request: bpf-next 2018-01-26 The following pull-request contains BPF updates for your *net-next* tree. The main changes are: 1) A number of extensions to tcp-bpf, from Lawrence. - direct R or R/W access to many tcp_sock fields via bpf_sock_ops - passing up to 3 arguments to bpf_sock_ops functions - tcp_sock field bpf_sock_ops_cb_flags for controlling callbacks - optionally calling bpf_sock_ops program when RTO fires - optionally calling bpf_sock_ops program when packet is retransmitted - optionally calling bpf_sock_ops program when TCP state changes - access to tclass and sk_txhash - new selftest 2) div/mod exception handling, from Daniel. One of the ugly leftovers from the early eBPF days is that div/mod operations based on registers have a hard-coded src_reg == 0 test in the interpreter as well as in JIT code generators that would return from the BPF program with exit code 0. This was basically adopted from cBPF interpreter for historical reasons. There are multiple reasons why this is very suboptimal and prone to bugs. To name one: the return code mapping for such abnormal program exit of 0 does not always match with a suitable program type's exit code mapping. For example, '0' in tc means action 'ok' where the packet gets passed further up the stack, which is just undesirable for such cases (e.g. when implementing policy) and also does not match with other program types. After considering _four_ different ways to address the problem, we adapt the same behavior as on some major archs like ARMv8: X div 0 results in 0, and X mod 0 results in X. aarch64 and aarch32 ISA do not generate any traps or otherwise aborts of program execution for unsigned divides. Given the options, it seems the most suitable from all of them, also since major archs have similar schemes in place. Given this is all in the realm of undefined behavior, we still have the option to adapt if deemed necessary. 3) sockmap sample refactoring, from John. 4) lpm map get_next_key fixes, from Yonghong. 5) test cleanups, from Alexei and Prashant. ==================== Signed-off-by: David S.

Since we know about the setting at compilation time anyway, just initialize it properly there. Also consolidate all the individual bpf_jit_enable variables into a single one and move them under one location. Moreover, don't allow for setting unspecified garbage values on them.

2018-01-16KVM: arm64: Handle RAS SErrors from EL1 on guest exitJames Morse1-0/+3
We expect to have firmware-first handling of RAS SErrors, with errors notified via an APEI method. For systems without firmware-first, add some minimal handling to KVM. There are two ways KVM can take an SError due to a guest, either may be a RAS error: we exit the guest due to an SError routed to EL2 by HCR_EL2.AMO, or we take an SError from EL2 when we unmask PSTATE.A from __guest_exit. For SError that interrupt a guest and are routed to EL2 the existing behaviour is to inject an impdef SError into the guest. Add code to handle RAS SError based on the ESR. For uncontained and uncategorized errors arm64_is_fatal_ras_serror() will panic(), these errors compromise the host too. All other error types are contained: For the fatal errors the vCPU can't make progress, so we inject a virtual SError. We ignore contained errors where we can make progress as if we're lucky, we may not hit them again. If only some of the CPUs support RAS the guest will see the cpufeature sanitised version of the id registers, but we may still take RAS SError on this CPU. Move the SError handling out of handle_exit() into a new handler that runs before we can be preempted. This allows us to use this_cpu_has_cap(), via arm64_is_ras_serror().

2018-01-16KVM: arm/arm64: mask/unmask daif around VHE guestsJames Morse1-0/+2
Non-VHE systems take an exception to EL2 in order to world-switch into the guest. When returning from the guest KVM implicitly restores the DAIF flags when it returns to the kernel at EL1. With VHE none of this exception-level jumping happens, so KVMs world-switch code is exposed to the host kernel's DAIF values, and KVM spills the guest-exit DAIF values back into the host kernel. On entry to a guest we have Debug and SError exceptions unmasked, KVM has switched VBAR but isn't prepared to handle these. On guest exit Debug exceptions are left disabled once we return to the host and will stay this way until we enter user space. Add a helper to mask/unmask DAIF around VHE guests. The unmask can only happen after the hosts VBAR value has been synchronised by the isb in __vhe_hyp_call (via kvm_call_hyp()). Masking could be as late as setting KVMs VBAR value, but is kept here for symmetry.

Setting si_code to 0 results in a userspace seeing an si_code of 0. This is the same si_code as SI_USER. Posix and common sense requires that SI_USER not be a signal specific si_code. As such this use of 0 for the si_code is a pretty horribly broken ABI. Further use of si_code == 0 guaranteed that copy_siginfo_to_user saw a value of __SI_KILL and now sees a value of SIL_KILL with the result that uid and pid fields are copied and which might copying the si_addr field by accident but certainly not by design. Making this a very flakey implementation. Utilizing FPE_FIXME, siginfo_layout will now return SIL_FAULT and the appropriate fields will be reliably copied.

2018-01-12crypto: hash - annotate algorithms taking optional keyEric Biggers1-0/+2
We need to consistently enforce that keyed hashes cannot be used without setting the key. To do this we need a reliable way to determine whether a given hash algorithm is keyed or not. AF_ALG currently does this by checking for the presence of a ->setkey() method. However, this is actually slightly broken because the CRC-32 algorithms implement ->setkey() but can also be used without a key. (The CRC-32 "key" is not actually a cryptographic key but rather represents the initial state. If not overridden, then a default initial state is used.) Prepare to fix this by introducing a flag CRYPTO_ALG_OPTIONAL_KEY which indicates that the algorithm has a ->setkey() method, but it is not required to be called. Then set it on all the CRC-32 algorithms. The same also applies to the Adler-32 implementation in Lustre. Also, the cryptd and mcryptd templates have to pass through the flag from their underlying algorithm.

2018-01-10dma-mapping: move dma_mark_clean to dma-direct.hChristoph Hellwig1-2/+0
And unlike the other helpers we don't require a <asm/dma-direct.h> as this helper is a special case for ia64 only, and this keeps it as simple as possible. Signed-off-by: Christoph Hellwig <hch@lst.de>
2018-01-10dma-mapping: move swiotlb arch helpers to a new headerChristoph Hellwig3-31/+37
phys_to_dma, dma_to_phys and dma_capable are helpers published by architecture code for use of swiotlb and xen-swiotlb only. Drivers are not supposed to use these directly, but use the DMA API instead. Move these to a new asm/dma-direct.h helper, included by a linux/dma-direct.h wrapper that provides the default linear mapping unless the architecture wants to override it. In the MIPS case the existing dma-coherent.h is reused for now as untangling it will take a bit of work. Signed-off-by: Christoph Hellwig <hch@lst.de> Acked-by: Robin Murphy <robin.murphy@arm.com>
