git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux Pull close_range() implementation from Christian Brauner: "This adds the close_range() syscall. It allows to efficiently close a range of file descriptors up to all file descriptors of a calling task. This is coordinated with the FreeBSD folks which have copied our version of this syscall and in the meantime have already merged it in April 2019: https://reviews.freebsd.org/D21627 https://svnweb.freebsd.org/base?view=revision&revision=359836 The syscall originally came up in a discussion around the new mount API and making new file descriptor types cloexec by default. During this discussion, Al suggested the close_range() syscall. First, it helps to close all file descriptors of an exec()ing task. This can be done safely via (quoting Al's example from [1] verbatim): /* that exec is sensitive */ unshare(CLONE_FILES); /* we don't want anything past stderr here */ close_range(3, ~0U); execve(....); The code snippet above is one way of working around the problem that file descriptors are not cloexec by default. This is aggravated by the fact that we can't just switch them over without massively regressing userspace. For a whole class of programs having an in-kernel method of closing all file descriptors is very helpful (e.g. demons, service managers, programming language standard libraries, container managers etc.). Second, it allows userspace to avoid implementing closing all file descriptors by parsing through /proc/<pid>/fd/* and calling close() on each file descriptor and other hacks. From looking at various large(ish) userspace code bases this or similar patterns are very common in service managers, container runtimes, and programming language runtimes/standard libraries such as Python or Rust. In addition, the syscall will also work for tasks that do not have procfs mounted and on kernels that do not have procfs support compiled in. In such situations the only way to make sure that all file descriptors are closed is to call close() on each file descriptor up to UINT_MAX or RLIMIT_NOFILE, OPEN_MAX trickery. Based on Linus' suggestion close_range() also comes with a new flag CLOSE_RANGE_UNSHARE to more elegantly handle file descriptor dropping right before exec. This would usually be expressed in the sequence: unshare(CLONE_FILES); close_range(3, ~0U); as pointed out by Linus it might be desirable to have this be a part of close_range() itself under a new flag CLOSE_RANGE_UNSHARE which gets especially handy when we're closing all file descriptors above a certain threshold. Test-suite as always included" * tag 'close-range-v5.9' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux: tests: add CLOSE_RANGE_UNSHARE tests close_range: add CLOSE_RANGE_UNSHARE tests: add close_range() tests arch: wire-up close_range() open: add close_range()
2020-08-04Merge tag 'fork-v5.9' of ↵Linus Torvalds2-4/+2
git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux Pull fork cleanups from Christian Brauner: "This is cleanup series from when we reworked a chunk of the process creation paths in the kernel and switched to struct {kernel_}clone_args. High-level this does two main things: - Remove the double export of both do_fork() and _do_fork() where do_fork() used the incosistent legacy clone calling convention. Now we only export _do_fork() which is based on struct kernel_clone_args. - Remove the copy_thread_tls()/copy_thread() split making the architecture specific HAVE_COYP_THREAD_TLS config option obsolete. This switches all remaining architectures to select HAVE_COPY_THREAD_TLS and thus to the copy_thread_tls() calling convention. The current split makes the process creation codepaths more convoluted than they need to be. Each architecture has their own copy_thread() function unless it selects HAVE_COPY_THREAD_TLS then it has a copy_thread_tls() function. The split is not needed anymore nowadays, all architectures support CLONE_SETTLS but quite a few of them never bothered to select HAVE_COPY_THREAD_TLS and instead simply continued to use copy_thread() and use the old calling convention. Removing this split cleans up the process creation codepaths and paves the way for implementing clone3() on such architectures since it requires the copy_thread_tls() calling convention. After having made each architectures support copy_thread_tls() this series simply renames that function back to copy_thread(). It also switches all architectures that call do_fork() directly over to _do_fork() and the struct kernel_clone_args calling convention. This is a corollary of switching the architectures that did not yet support it over to copy_thread_tls() since do_fork() is conditional on not supporting copy_thread_tls() (Mostly because it lacks a separate argument for tls which is trivial to fix but there's no need for this function to exist.). The do_fork() removal is in itself already useful as it allows to to remove the export of both do_fork() and _do_fork() we currently have in favor of only _do_fork(). This has already been discussed back when we added clone3(). The legacy clone() calling convention is - as is probably well-known - somewhat odd: # # ABI hall of shame # config CLONE_BACKWARDS config CLONE_BACKWARDS2 config CLONE_BACKWARDS3 that is aggravated by the fact that some architectures such as sparc follow the CLONE_BACKWARDSx calling convention but don't really select the corresponding config option since they call do_fork() directly. So do_fork() enforces a somewhat arbitrary calling convention in the first place that doesn't really help the individual architectures that deviate from it. They can thus simply be switched to _do_fork() enforcing a single calling convention. (I really hope that any new architectures will __not__ try to implement their own calling conventions...) Most architectures already have made a similar switch (m68k comes to mind). Overall this removes more code than it adds even with a good portion of added comments. It simplifies a chunk of arch specific assembly either by moving the code into C or by simply rewriting the assembly. Architectures that have been touched in non-trivial ways have all been actually boot and stress tested: sparc and ia64 have been tested with Debian 9 images. They are the two architectures which have been touched the most. All non-trivial changes to architectures have seen acks from the relevant maintainers. nios2 with a custom built buildroot image. h8300 I couldn't get something bootable to test on but the changes have been fairly automatic and I'm sure we'll hear people yell if I broke something there. All other architectures that have been touched in trivial ways have been compile tested for each single patch of the series via git rebase -x "make ..." v5.8-rc2. arm{64} and x86{_64} have been boot tested even though they have just been trivially touched (removal of the HAVE_COPY_THREAD_TLS macro from their Kconfig) because well they are basically "core architectures" and since it is trivial to get your hands on a useable image" * tag 'fork-v5.9' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux: arch: rename copy_thread_tls() back to copy_thread() arch: remove HAVE_COPY_THREAD_TLS unicore: switch to copy_thread_tls() sh: switch to copy_thread_tls() nds32: switch to copy_thread_tls() microblaze: switch to copy_thread_tls() hexagon: switch to copy_thread_tls() c6x: switch to copy_thread_tls() alpha: switch to copy_thread_tls() fork: remove do_fork() h8300: select HAVE_COPY_THREAD_TLS, switch to kernel_clone_args nios2: enable HAVE_COPY_THREAD_TLS, switch to kernel_clone_args ia64: enable HAVE_COPY_THREAD_TLS, switch to kernel_clone_args sparc: unconditionally enable HAVE_COPY_THREAD_TLS sparc: share process creation helpers between sparc and sparc64 sparc64: enable HAVE_COPY_THREAD_TLS fork: fold legacy_clone_args_valid() into _do_fork()

A larger driver for the Tegra memory controller that was accidentally missed for v5.8 is now added. - reset controllers: Only minor updates to drivers/reset this time - firmware: The "turris mox" firmware driver gains support for signed firmware blobs The tegra firmware driver gets extended to export some debug information Various updates to i.MX firmware drivers, mostly cosmetic - ARM SCMI/SCPI: A new mechanism for platform notifications is added, among a number of minor changes. - optee: Probing of the TEE bus is rewritten to better support detection of devices that depend on the tee-supplicant user space. A new firmware based trusted platform module (fTPM) driver is added based on OP-TEE - SoC attributes: A new driver is added to provide a generic soc_device for identifying a machine through the SMCCC ARCH_SOC_ID firmware interface rather than by probing SoC family specific registers. The series also contains some cleanups to the common soc_device code. There are also a number of updates to SoC specific drivers, the main ones are: - Mediatek cmdq driver gains a few in-kernel interfaces - Minor updates to Qualcomm RPMh, socinfo, rpm drivers, mostly adding support for additional SoC variants - The Qualcomm GENI core code gains interconnect path voting and performance level support, and integrating this into a number of device drivers. - A new driver for Samsung Exynos5800 voltage coupler for - Renesas RZ/G2H (R8A774E1) SoC support gets added to a couple of SoC specific device drivers - Updates to the TI K3 Ring Accelerator driver" * tag 'arm-drivers-5.9' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (164 commits) soc: qcom: geni: Fix unused label warning soc: qcom: smd-rpm: Fix kerneldoc memory: jz4780_nemc: Only request IO memory the driver will use soc: qcom: pdr: Reorder the PD state indication ack MAINTAINERS: Add Git repository for memory controller drivers memory: brcmstb_dpfe: Fix language typo memory: samsung: exynos5422-dmc: Correct white space issues memory: samsung: exynos-srom: Correct alignment memory: pl172: Enclose macro argument usage in parenthesis memory: of: Correct kerneldoc memory: omap-gpmc: Fix language typo memory: omap-gpmc: Correct white space issues memory: omap-gpmc: Use 'unsigned int' for consistency memory: omap-gpmc: Enclose macro argument usage in parenthesis memory: omap-gpmc: Correct kerneldoc memory: mvebu-devbus: Align with open parenthesis memory: mvebu-devbus: Add missing braces to all arms of if statement memory: bt1-l2-ctl: Add blank lines after declarations soc: TI knav_qmss: make symbol 'knav_acc_range_ops' static firmware: ti_sci: Replace HTTP links with HTTPS ones ...

Pull ARM SoC DT updates from Arnd Bergmann: "As usual, there are many patches addressing minor issues in existing DTS files, such as DTC warnings, or adding support for additional peripherals. There are three added SoCs in existing product families: - Amazon: Alpine v3 is a 16-core Cortex-A72 SoC from Amazon's Annapurna Labs, otherwise known as AL73400 or first-generation Graviton, and following the already supported Cortex-A1`5 and Cortex-A57 based Alpine chips. This one is added together with the official Evaluation platform. - Qualcomm: The Snapdragon SDM630 platform is a family of mid-range mobile phone chips from 2017 based on Cortex-A53 or Kryo 260 CPUs. A total of five end-user products are added based on these, all Android phones from Sony: Xperia 10, 10 Plus, XA2, XA2 Plus and XA2 Ultra. - Renesas: RZ/G2H (r8a774e1) is currently the top model in the Renesas RZ/G family, and apparently closely related to the RZ/G2N and RZ/G2M models we already support but has a faster GPU and additional on-chip peripherals. It is added along with the HopeRun HiHope RZ/G2H development board A small number of new boards for already supported SoCs also debut: - Allwinner sunxi: Only one new machine, revision v1.2 of the Pine64 PinePhone (non-Android) smartphone, containing minor changes compared to earlier versions. - Amlogic Meson: WeTek Core2 is an Amlogic S912 (GXM) based Set-top-box - Aspeed: EthanolX is AMD's EPYC data center rerence platform, using an ASpeed AST2600 baseboard management controller. - Mediatek: Lenovo IdeaPad Duet 10.1" (kukui/krane) is a new Chromebook based on the MT8183 (Helio P60t) SoC. - Nvidia Tegra: ASUS Google Nexus 7 and Acer Iconia Tab A500 are two Android tablets from around 2012 using Tegra 3 and Tegra 2, respectively. Thanks to PostmarketOS, these can now run mainline kernels and become useful again. The Jetson Xavier NX Developer Kit uses a SoM and carrier board for the Tegra194, their latest 64-bit chip based on Carmel CPU cores and Volta graphics. - NXP i.MX: Five new boards based on the 32-bit i.MX6 series are added: The MYiR MYS-6ULX single-board computer, and four different models of industrial computers from Protonic. - Qualcomm: MikroTik RouterBoard 3011 is a rackmounted router based on the 32-bit IPQ8064 networking SoC Three older phones get added, the Snapdragon 808 (msm8992) based Xiaomi Libra (Mi 4C) and Microsoft Lumia 950, originally running Windows Phone, and the Snapdragon 810 (msm8994) based Sony Xperia Z5. - Renesas: In addition to the HiHope RZ/G2H board mentioned above, we gain support for board versions 3.0 and 4.0 of the earlier RZ/G2M and RZ/G2N reference boards. Beacon EmbeddedWorks adds another SoM+Carrier development board for RZ/G2M. - Rockchips: Radxa Rock Pi N8 development board and the VMARC RK3288 SoM it is based on, using the high-end 32-bit rk3288 SoC.

git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux Pull arm64 and cross-arch updates from Catalin Marinas: "Here's a slightly wider-spread set of updates for 5.9. Going outside the usual arch/arm64/ area is the removal of read_barrier_depends() series from Will and the MSI/IOMMU ID translation series from Lorenzo. The notable arm64 updates include ARMv8.4 TLBI range operations and translation level hint, time namespace support, and perf. Summary: - Removal of the tremendously unpopular read_barrier_depends() barrier, which is a NOP on all architectures apart from Alpha, in favour of allowing architectures to override READ_ONCE() and do whatever dance they need to do to ensure address dependencies provide LOAD -> LOAD/STORE ordering. This work also offers a potential solution if compilers are shown to convert LOAD -> LOAD address dependencies into control dependencies (e.g. under LTO), as weakly ordered architectures will effectively be able to upgrade READ_ONCE() to smp_load_acquire(). The latter case is not used yet, but will be discussed further at LPC. - Make the MSI/IOMMU input/output ID translation PCI agnostic, augment the MSI/IOMMU ACPI/OF ID mapping APIs to accept an input ID bus-specific parameter and apply the resulting changes to the device ID space provided by the Freescale FSL bus. - arm64 support for TLBI range operations and translation table level hints (part of the ARMv8.4 architecture version). - Time namespace support for arm64. - Export the virtual and physical address sizes in vmcoreinfo for makedumpfile and crash utilities. - CPU feature handling cleanups and checks for programmer errors (overlapping bit-fields). - ACPI updates for arm64: disallow AML accesses to EFI code regions and kernel memory. - perf updates for arm64. - Miscellaneous fixes and cleanups, most notably PLT counting optimisation for module loading, recordmcount fix to ignore relocations other than R_AARCH64_CALL26, CMA areas reserved for gigantic pages on 16K and 64K configurations. - Trivial typos, duplicate words" Link: http://lkml.kernel.org/r/20200710165203.31284-1-will@kernel.org Link: http://lkml.kernel.org/r/20200619082013.13661-1-lorenzo.pieralisi@arm.com * tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: (82 commits) arm64: use IRQ_STACK_SIZE instead of THREAD_SIZE for irq stack arm64/mm: save memory access in check_and_switch_context() fast switch path arm64: sigcontext.h: delete duplicated word arm64: ptrace.h: delete duplicated word arm64: pgtable-hwdef.h: delete duplicated words bus: fsl-mc: Add ACPI support for fsl-mc bus/fsl-mc: Refactor the MSI domain creation in the DPRC driver of/irq: Make of_msi_map_rid() PCI bus agnostic of/irq: make of_msi_map_get_device_domain() bus agnostic dt-bindings: arm: fsl: Add msi-map device-tree binding for fsl-mc bus of/device: Add input id to of_dma_configure() of/iommu: Make of_map_rid() PCI agnostic ACPI/IORT: Add an input ID to acpi_dma_configure() ACPI/IORT: Remove useless PCI bus walk ACPI/IORT: Make iort_msi_map_rid() PCI agnostic ACPI/IORT: Make iort_get_device_domain IRQ domain agnostic ACPI/IORT: Make iort_match_node_callback walk the ACPI namespace for NC arm64: enable time namespace support arm64/vdso: Restrict splitting VVAR VMA arm64/vdso: Handle faults on timens page ...

2020-07-28ARM: mstar: Add reboot supportDaniel Palmer1-0/+7
MStar v7 SoCs support reset by writing a magic value to a register in the "pmsleep" area. This adds a node for using the syscon reboot driver to trigger a reset. Signed-off-by: Daniel Palmer <daniel@0x0f.com> Signed-off-by: Arnd Bergmann <arnd@arndb.de>

2020-07-28ARM: mstar: Add IMI SRAM regionDaniel Palmer1-1/+7
All MStar v7 SoCs have an internal SRAM region that is between 64KB (infinity2m) and 128KB(infinity3, mercury5). The region is always at the same base address and is used for the second stage loader (MStar IPL or u-boot SPL) and will be used for the DDR self-refresh entry code within the kernel eventually. This patch adds a 128KB region to the SoC and the minimum 64KB SRAM region to the base dtsi. Families with more SRAM will override the size in their family level dtsi.
