2021-04-27Merge tag 'cfi-v5.13-rc1' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux Pull CFI on arm64 support from Kees Cook: "This builds on last cycle's LTO work, and allows the arm64 kernels to be built with Clang's Control Flow Integrity feature. This feature has happily lived in Android kernels for almost 3 years[1], so I'm excited to have it ready for upstream. The wide diffstat is mainly due to the treewide fixing of mismatched list_sort prototypes. Other things in core kernel are to address various CFI corner cases. The largest code portion is the CFI runtime implementation itself (which will be shared by all architectures implementing support for CFI). The arm64 pieces are Acked by arm64 maintainers rather than coming through the arm64 tree since carrying this tree over there was going to be awkward. CFI support for x86 is still under development, but is pretty close. There are a handful of corner cases on x86 that need some improvements to Clang and objtool, but otherwise works well. Summary: - Clean up list_sort prototypes (Sami Tolvanen) - Introduce CONFIG_CFI_CLANG for arm64 (Sami Tolvanen)" * tag 'cfi-v5.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux: arm64: allow CONFIG_CFI_CLANG to be selected KVM: arm64: Disable CFI for nVHE arm64: ftrace: use function_nocfi for ftrace_call arm64: add __nocfi to __apply_alternatives arm64: add __nocfi to functions that jump to a physical address arm64: use function_nocfi with __pa_symbol arm64: implement function_nocfi psci: use function_nocfi for cpu_resume lkdtm: use function_nocfi treewide: Change list_sort to use const pointers bpf: disable CFI in dispatcher functions kallsyms: strip ThinLTO hashes from static functions kthread: use WARN_ON_FUNCTION_MISMATCH workqueue: use WARN_ON_FUNCTION_MISMATCH module: ensure __cfi_check alignment mm: add generic function_nocfi macro cfi: add __cficanonical add support for Clang CFI

Pull ARM devicetree updates from Arnd Bergmann: "There are six new SoCs added this time. Apple M1 and Nuvoton WPCM450 have separate branches because they are new SoC families that require changes outside of device tree files. The other four are variations of already supported chips and get merged through this branch: - STMicroelectronics STM32H750 is one of many variants of STM32 microcontrollers based on the Cortex-M7 core. This is particularly notable since we rarely add support for new MMU-less chips these days. In this case, the board that gets added along with the platform is not a SoC reference platform but the "Art Pi" (https://art-pi.gitee.io/website/) machine that was originally design for the RT-Thread RTOS. - NXP i.MX8QuadMax is a variant of the growing i.MX8 embedded/industrial SoC family, using two Cortex-A72 and four Cortex-A53 cores. It gets added along with its reference board, the "NXP i.MX8QuadMax Multisensory Enablement Kit". - Qualcomm SC7280 is a Laptop SoC following the SC7180 (Snapdragon 7c) that is used in some Chromebooks and Windows laptops. Only a reference board is added for the moment. - TI AM64x Sita4ra is a new version of the K3 SoC family for industrial control, motor control, remote IO, IoT gateway etc., similar to the older AM65x family. Two reference machines are added alongside. Among the newly added machines, there is a very clear skew towards 64-bit machines now, with 12 32-bit machines compared to 23 64-bit machines.

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull entry code update from Thomas Gleixner: "Provide support for randomized stack offsets per syscall to make stack-based attacks harder which rely on the deterministic stack layout. The feature is based on the original idea of PaX's RANDSTACK feature, but uses a significantly different implementation. The offset does not affect the pt_regs location on the task stack as this was agreed on to be of dubious value. The offset is applied before the actual syscall is invoked. The offset is stored per cpu and the randomization happens at the end of the syscall which is less predictable than on syscall entry. The mechanism to apply the offset is via alloca(), i.e. abusing the dispised VLAs. This comes with the drawback that stack-clash-protection has to be disabled for the affected compilation units and there is also a negative interaction with stack-protector. Those downsides are traded with the advantage that this approach does not require any intrusive changes to the low level assembly entry code, does not affect the unwinder and the correct stack alignment is handled automatically by the compiler. The feature is guarded with a static branch which avoids the overhead when disabled. Currently this is supported for X86 and ARM64" * tag 'x86-entry-2021-04-26' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: arm64: entry: Enable random_kstack_offset support lkdtm: Add REPORT_STACK for checking stack offsets x86/entry: Enable random_kstack_offset support stack: Optionally randomize kernel stack offset each syscall init_on_alloc: Optimize static branches jump_label: Provide CONFIG-driven build state defaults

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull irq updates from Thomas Gleixner: "The usual updates from the irq departement: Core changes: - Provide IRQF_NO_AUTOEN as a flag for request*_irq() so drivers can be cleaned up which either use a seperate mechanism to prevent auto-enable at request time or have a racy mechanism which disables the interrupt right after request. - Get rid of the last usage of irq_create_identity_mapping() and remove the interface. - An overhaul of tasklet_disable(). Most usage sites of tasklet_disable() are in task context and usually in cleanup, teardown code pathes. tasklet_disable() spinwaits for a tasklet which is currently executed. That's not only a problem for PREEMPT_RT where this can lead to a live lock when the disabling task preempts the softirq thread. It's also problematic in context of virtualization when the vCPU which runs the tasklet is scheduled out and the disabling code has to spin wait until it's scheduled back in. There are a few code pathes which invoke tasklet_disable() from non-sleepable context. For these a new disable variant which still spinwaits is provided which allows to switch tasklet_disable() to a sleep wait mechanism. For the atomic use cases this does not solve the live lock issue on PREEMPT_RT. That is mitigated by blocking on the RT specific softirq lock. - The PREEMPT_RT specific implementation of softirq processing and local_bh_disable/enable(). On RT enabled kernels soft interrupt processing happens always in task context and all interrupt handlers, which are not explicitly marked to be invoked in hard interrupt context are forced into task context as well. This allows to protect against softirq processing with a per CPU lock, which in turn allows to make BH disabled regions preemptible. Most of the softirq handling code is still shared. The RT/non-RT specific differences are addressed with a set of inline functions which provide the context specific functionality. The local_bh_disable() / local_bh_enable() mechanism are obviously seperate. - The usual set of small improvements and cleanups Driver changes: - New drivers for Nuvoton WPCM450 and DT 79rc3243x interrupt controllers - Extended functionality for MStar, STM32 and SC7280 irq chips - Enhanced robustness for ARM GICv3/4.1 drivers - The usual set of cleanups and improvements all over the place" * tag 'irq-core-2021-04-26' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (53 commits) irqchip/xilinx: Expose Kconfig option for Zynq/ZynqMP irqchip/gic-v3: Do not enable irqs when handling spurious interrups dt-bindings: interrupt-controller: Add IDT 79RC3243x Interrupt Controller irqchip: Add support for IDT 79rc3243x interrupt controller irqdomain: Drop references to recusive irqdomain setup irqdomain: Get rid of irq_create_strict_mappings() irqchip/jcore-aic: Kill use of irq_create_strict_mappings() ARM: PXA: Kill use of irq_create_strict_mappings() irqchip/gic-v4.1: Disable vSGI upon (GIC CPUIF < v4.1) detection irqchip/tb10x: Use 'fallthrough' to eliminate a warning genirq: Reduce irqdebug cacheline bouncing kernel: Initialize cpumask before parsing irqchip/wpcm450: Drop COMPILE_TEST irqchip/irq-mst: Support polarity configuration irqchip: Add driver for WPCM450 interrupt controller dt-bindings: interrupt-controller: Add nuvoton, wpcm450-aic dt-bindings: qcom,pdc: Add compatible for sc7280 irqchip/stm32: Add usart instances exti direct event support irqchip/gic-v3: Fix OF_BAD_ADDR error handling irqchip/sifive-plic: Mark two global variables __ro_after_init ...

2021-04-22perf/x86/kvm: Fix Broadwell Xeon stepping in isolation_ucodes[]Jim Mattson
The only stepping of Broadwell Xeon parts is stepping 1. Fix the relevant isolation_ucodes[] entry, which previously enumerated stepping 2. Although the original commit was characterized as an optimization, it is also a workaround for a correctness issue. If a PMI arrives between kvm's call to perf_guest_get_msrs() and the subsequent VM-entry, a stale value for the IA32_PEBS_ENABLE MSR may be restored at the next VM-exit. This is because, unbeknownst to kvm, PMI throttling may clear bits in the IA32_PEBS_ENABLE MSR. CPUs with "PEBS isolation" don't suffer from this issue, because perf_guest_get_msrs() doesn't report the IA32_PEBS_ENABLE value.

2021-04-22arm64: dts: allwinner: Revert SD card CD GPIO for Pine64-LTSAndre Przywara
Commit 941432d00768 ("arm64: dts: allwinner: Drop non-removable from SoPine/LTS SD card") enabled the card detect GPIO for the SOPine module, along the way with the Pine64-LTS, which share the same base .dtsi. This was based on the observation that the Pine64-LTS has as "push-push" SD card socket, and that the schematic mentions the card detect GPIO. After having received two reports about failing SD card access with that patch, some more research and polls on that subject revealed that there are at least two different versions of the Pine64-LTS out there: - On some boards (including mine) the card detect pin is "stuck" at high, regardless of an microSD card being inserted or not. - On other boards the card-detect is working, but is active-high, by virtue of an explicit inverter circuit, as shown in the schematic. To cover all versions of the board out there, and don't take any chances, let's revert the introduction of the active-low CD GPIO, but let's use the broken-cd property for the Pine64-LTS this time. That should avoid regressions and should work for everyone, even allowing SD card changes now. The SOPine card detect has proven to be working, so let's keep that GPIO in place.

2021-04-21PM: hibernate: x86: Use crc32 instead of md5 for hibernation e820 integrity ↵Chris von Recklinghausen
check Hibernation fails on a system in fips mode because md5 is used for the e820 integrity check and is not available. Use crc32 instead. The check is intended to detect whether the E820 memory map provided by the firmware after cold boot unexpectedly differs from the one that was in use when the hibernation image was created. In this case, the hibernation image cannot be restored, as it may cover memory regions that are no longer available to the OS. A non-cryptographic checksum such as CRC-32 is sufficient to detect such inadvertent deviations.
