2019-01-02Merge branch 'next-integrity' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security Pull integrity updates from James Morris: "In Linux 4.19, a new LSM hook named security_kernel_load_data was upstreamed, allowing LSMs and IMA to prevent the kexec_load syscall. Different signature verification methods exist for verifying the kexec'ed kernel image. This adds additional support in IMA to prevent loading unsigned kernel images via the kexec_load syscall, independently of the IMA policy rules, based on the runtime "secure boot" flag. An initial IMA kselftest is included. In addition, this pull request defines a new, separate keyring named ".platform" for storing the preboot/firmware keys needed for verifying the kexec'ed kernel image's signature and includes the associated IMA kexec usage of the ".platform" keyring. (David Howell's and Josh Boyer's patches for reading the preboot/firmware keys, which were previously posted for a different use case scenario, are included here)" * 'next-integrity' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security: integrity: Remove references to module keyring ima: Use inode_is_open_for_write ima: Support platform keyring for kernel appraisal efi: Allow the "db" UEFI variable to be suppressed efi: Import certificates from UEFI Secure Boot efi: Add an EFI signature blob parser efi: Add EFI signature data types integrity: Load certs to the platform keyring integrity: Define a trusted platform keyring selftests/ima: kexec_load syscall test ima: don't measure/appraise files on efivarfs x86/ima: retry detecting secure boot mode docs: Extend trusted keys documentation for TPM 2.0 x86/ima: define arch_get_ima_policy() for x86 ima: add support for arch specific policies ima: refactor ima_init_policy() ima: prevent kexec_load syscall based on runtime secureboot flag x86/ima: define arch_ima_get_secureboot integrity: support new struct public_key_signature encoding field

git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu Pull IOMMU updates from Joerg Roedel: - Page table code for AMD IOMMU now supports large pages where smaller page-sizes were mapped before. VFIO had to work around that in the past and I included a patch to remove it (acked by Alex Williamson) - Patches to unmodularize a couple of IOMMU drivers that would never work as modules anyway. - Work to unify the the iommu-related pointers in 'struct device' into one pointer. This work is not finished yet, but will probably be in the next cycle. - NUMA aware allocation in iommu-dma code - Support for r8a774a1 and r8a774c0 in the Renesas IOMMU driver - Scalable mode support for the Intel VT-d driver - PM runtime improvements for the ARM-SMMU driver - Support for the QCOM-SMMUv2 IOMMU hardware from Qualcom - Various smaller fixes and improvements * tag 'iommu-updates-v4.21' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: (78 commits) iommu: Check for iommu_ops == NULL in iommu_probe_device() ACPI/IORT: Don't call iommu_ops->add_device directly iommu/of: Don't call iommu_ops->add_device directly iommu: Consolitate ->add/remove_device() calls iommu/sysfs: Rename iommu_release_device() dmaengine: sh: rcar-dmac: Use device_iommu_mapped() xhci: Use device_iommu_mapped() powerpc/iommu: Use device_iommu_mapped() ACPI/IORT: Use device_iommu_mapped() iommu/of: Use device_iommu_mapped() driver core: Introduce device_iommu_mapped() function iommu/tegra: Use helper functions to access dev->iommu_fwspec iommu/qcom: Use helper functions to access dev->iommu_fwspec iommu/of: Use helper functions to access dev->iommu_fwspec iommu/mediatek: Use helper functions to access dev->iommu_fwspec iommu/ipmmu-vmsa: Use helper functions to access dev->iommu_fwspec iommu/dma: Use helper functions to access dev->iommu_fwspec iommu/arm-smmu: Use helper functions to access dev->iommu_fwspec ACPI/IORT: Use helper functions to access dev->iommu_fwspec iommu: Introduce wrappers around dev->iommu_fwspec ...

git://git.kernel.org/pub/scm/linux/kernel/git/danielt/linux Pull kgdb updates from Daniel Thompson: "Mostly clean ups although while Doug's was chasing down a odd lockdep warning he also did some work to improved debugger resilience when some CPUs fail to respond to the round up request. The main changes are: - Fixing a lockdep warning on architectures that cannot use an NMI for the round up plus related changes to make CPU round up and all CPU backtrace more resilient. - Constify the arch ops tables - A couple of other small clean ups Two of the three patchsets here include changes that spill over into arch/.

2018-12-31Merge tag 'armsoc-defconfig' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC defconfig updates from Olof Johansson: "Most changes here are to enable new drivers and platforms in the various configs that affect them. Most of these have been covered and described in the other branches, we mostly keep defconfig separate to avoid conflicts between SoC/dt/driver updates that they otherwise would be grouped with. One thing worth mentioning here is that OMAP changes from using their own UART driver, to 8250, for the multi_v7_defconfig shared config on 32-bit. This means that the console is now named ttyS* instead of ttyO*. This change was already done for omap2_defconfig a while back, so most users of these configs have either already updated, or can easily follow the same patterns as they did at that time. This makes platform support slightly easier for distros, since they no longer need to keep track of a separate console prefix for these platforms" * tag 'armsoc-defconfig' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (31 commits) Revert "arm64: defconfig: Enable FSL_MC_BUS and FSL_MC_DPIO" arm64: defconfig: Enable FSL_MC_BUS and FSL_MC_DPIO arm64: defconfig: Replace PINCTRL_MT7622 with PINCTRL_MTK_MOORE arm64: defconfig: Regenerate for v4.20 ARM: multi_v7_defconfig: Add TOSHIBA TC358764 bridge driver ARM: multi_v7_defconfig: Add MAX8952 regulator driver ARM: exynos_defconfig: Add TOSHIBA TC358764 bridge driver ARM: exynos_defconfig: Add MAX8952 regulator driver ARM: exynos_defconfig: Add MAX8998 RTC and charger drivers ARM: imx_v6_v7_defconfig: add imx7ulp support ARM: imx_v6_v7_defconfig: Select TOUCHSCREEN_GOODIX ARM: multi_v7_defconfig: enable STM32 analog & timer drivers arm64: defconfig: Enable GCC and PINCTRL for MSM8998 arm64: defconfig: Enable core Qualcomm SDM845 options ARM: defconfig: Enable the PL111 DRM driver on vexpress ARM: defconfig: Update the vexpress defconfig arm64: defconfig: Enable some qcom remoteproc configs arm64: defconfig: Enable QCS404 configs ARM: imx_v6_v7_defconfig: Enable USB_ANNOUNCE_NEW_DEVICES ARM: imx_v6_v7_defconfig: Enable BT_BNEP ...

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM Device-tree updates from Olof Johansson: "As usual, this is where the bulk of our changes end up landing each merge window. The individual updates are too many to enumerate, many many platforms have seen additions of device descriptions such that they are functionally more complete (in fact, this is often the bulk of updates we see). Instead I've mostly focused on highlighting the new platforms below as they are introduced. Sometimes the introduction is of mostly a fragment, that later gets filled in on later releases, and in some cases it's near-complete platform support. The latter is more common for derivative platforms that already has similar support in-tree. Two SoCs are slight outliers from the usual range of additions. Allwinner support for F1C100s, a quite old SoC (ARMv5-based) shipping in the Lychee Pi Nano platform. At the other end is NXP Layerscape LX2160A, a 16-core 2.2GHz Cortex-A72 SoC with a large amount of I/O aimed at infrastructure/networking. TI updates stick out in the diff stats too, in particular because they have moved the description of their L4 on-chip interconnect to devicetree, which opens up for removal of even more of their platform-specific 'hwmod' description tables over the next few releases. SoCs: - Qualcomm QCS404 (4x Cortex-A53) - Allwinner T3 (rebranded R40) and f1c100s (armv5) - NXP i.MX7ULP (1x Cortex-A7 + 1x Cortex-M4) - NXP LS1028A (2x Cortex-A72), LX2160A (16x Cortex-A72) New platforms: - Rockchip: Gru Scarlet (RK3188 Tablet) - Amlogic: Phicomm N1 (S905D), Libretech S805-AC - Broadcom: Linksys EA6500 v2 Wi-Fi router (BCM4708) - Qualcomm: QCS404 base platform and EVB - Qualcomm: Remove of Arrow SD600 - PXA: First PXA3xx DT board: Raumfeld - Aspeed: Facebook Backpack-CMM BMC - Renesas iWave G20D-Q7 (RZ/G1N) - Allwinner t3-cqa3t-bv3 (T3/R40) and Lichee Pi Nano (F1C100s) - Allwinner Emlid Neutis N5, Mapleboard MP130 - Marvell Macchiatobin Single Shot (Armada 8040, no 10GbE) - i.MX: mtrion emCON-MX6, imx6ul-pico-pi, imx7d-sdb-reva - VF610: Liebherr's BK4 device, ZII SCU4 AIB board - i.MX7D PICO Hobbit baseboard - i.MX7ULP EVK board - NXP LX2160AQDS and LX2160ARDB boards Other: - Coresight binding updates across the board - CPU cooling maps updates across the board" * tag 'armsoc-dt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (648 commits) ARM: dts: suniv: Fix improper bindings include patch ARM: dts: sunxi: Enable Broadcom-based Bluetooth for multiple boards arm64: dts: allwinner: a64: bananapi-m64: Add Bluetooth device node ARM: dts: suniv: Fix improper bindings include patch arm64: dts: Add spi-[tx/rx]-bus-width for the FSL QSPI controller arm64: dts: Remove unused properties from FSL QSPI driver nodes ARM: dts: Add spi-[tx/rx]-bus-width for the FSL QSPI controller ARM: dts: imx6sx-sdb: Fix the reg properties for the FSL QSPI nodes ARM: dts: Remove unused properties from FSL QSPI driver nodes arm64: dts: ti: k3-am654: Enable main domain McSPI0 arm64: dts: ti: k3-am654: Add McSPI DT nodes arm64: dts: ti: k3-am654: Populate power-domain property for UART nodes arm64: dts: ti: k3-am654-base-board: Enable ECAP PWM arm64: dts: ti: k3-am65-main: Add ECAP PWM node arm64: dts: ti: k3-am654-base-board: Add I2C nodes arm64: dts: ti: am654-base-board: Add pinmux for main uart0 arm64: dts: ti: k3-am65: Add pinctrl regions dt-bindings: pinctrl: k3: Introduce pinmux definitions ARM: dts: exynos: Specify I2S assigned clocks in proper node ARM: dts: exynos: Add missing CPUs in cooling maps for Odroid X2 ...

git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull tracing updates from Steven Rostedt: - Rework of the kprobe/uprobe and synthetic events to consolidate all the dynamic event code. This will make changes in the future easier. - Partial rewrite of the function graph tracing infrastructure. This will allow for multiple users of hooking onto functions to get the callback (return) of the function. This is the ground work for having kprobes and function graph tracer using one code base. - Clean up of the histogram code that will facilitate adding more features to the histograms in the future. - Addition of str_has_prefix() and a few use cases. There currently is a similar function strstart() that is used in a few places, but only returns a bool and not a length. These instances will be removed in the future to use str_has_prefix() instead. - A few other various clean ups as well. * tag 'trace-v4.21' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: (57 commits) tracing: Use the return of str_has_prefix() to remove open coded numbers tracing: Have the historgram use the result of str_has_prefix() for len of prefix tracing: Use str_has_prefix() instead of using fixed sizes tracing: Use str_has_prefix() helper for histogram code string.h: Add str_has_prefix() helper function tracing: Make function ‘ftrace_exports’ static tracing: Simplify printf'ing in seq_print_sym tracing: Avoid -Wformat-nonliteral warning tracing: Merge seq_print_sym_short() and seq_print_sym_offset() tracing: Add hist trigger comments for variable-related fields tracing: Remove hist trigger synth_var_refs tracing: Use hist trigger's var_ref array to destroy var_refs tracing: Remove open-coding of hist trigger var_ref management tracing: Use var_refs[] for hist trigger reference checking tracing: Change strlen to sizeof for hist trigger static strings tracing: Remove unnecessary hist trigger struct field tracing: Fix ftrace_graph_get_ret_stack() to use task and not current seq_buf: Use size_t for len in seq_buf_puts() seq_buf: Make seq_buf_puts() null-terminate the buffer arm64: Use ftrace_graph_get_ret_stack() instead of curr_ret_stack ...

If nothing else that seems like it could violate spinlock semantics and cause a deadlock. Instead, let's use a private csd alongside smp_call_function_single_async() to round up the other CPUs. Using smp_call_function_single_async() doesn't require interrupts to be enabled so we can remove the offending bit of code. In order to avoid duplicating this across all the architectures that use the default kgdb_roundup_cpus(), we'll add a "weak" implementation to debug_core.c. Looking at all the people who previously had copies of this code, there were a few variants. I've attempted to keep the variants working like they used to. Specifically: * For arch/arc we passed NULL to kgdb_nmicallback() instead of get_irq_regs(). * For arch/mips there was a bit of extra code around kgdb_nmicallback() NOTE: In this patch we will still get into trouble if we try to round up a CPU that failed to round up before. We'll try to round it up again and potentially hang when we try to grab the csd lock. That's not new behavior but we'll still try to do better in a future patch.
