2022-12-30crypto: arm64/sm4 - fix possible crash with CFI enabledTianjia Zhang2-4/+6
The SM4 CCM/GCM assembly functions for encryption and decryption is called via indirect function calls. Therefore they need to use SYM_TYPED_FUNC_START instead of SYM_FUNC_START to cause its type hash to be emitted when the kernel is built with CONFIG_CFI_CLANG=y. Otherwise, the code crashes with a CFI failure (if the compiler didn't happen to optimize out the indirect call). Fixes: 67fa3a7fdf80 ("crypto: arm64/sm4 - add CE implementation for CCM mode") Fixes: ae1b83c7d572 ("crypto: arm64/sm4 - add CE implementation for GCM mode") Signed-off-by: Tianjia Zhang <tianjia.zhang@linux.alibaba.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

The actual clock feeding into the Mali GPU on the MT8183 is from the clock gate in the MFGCFG block, not CLK_TOP_MFGPLL_CK from the TOPCKGEN block, which itself is simply a pass-through placeholder for the MFGPLL in the APMIXEDSYS block.

2022-12-16arm64: dts: mediatek: mt8195-demo: fix the memory size of node secmonMacpaul Lin1-2/+2
The size of device tree node secmon (bl31_secmon_reserved) was incorrect. It should be increased to 2MiB (0x200000). The origin setting will cause some abnormal behavior due to trusted-firmware-a and related firmware didn't load correctly. The incorrect behavior may vary because of different software stacks. For example, it will cause build error in some Yocto project because it will check if there was enough memory to load trusted-firmware-a to the reserved memory. When mt8195-demo.dts sent to the upstream, at that time the size of BL31 was small. Because supported functions and modules in BL31 are basic sets when the board was under early development stage. Now BL31 includes more firmwares of coprocessors and maturer functions so the size has grown bigger in real applications. According to the value reported by customers, we think reserved 2MiB for BL31 might be enough for maybe the following 2 or 3 years.

Pull kvm updates from Paolo Bonzini: "ARM64: - Enable the per-vcpu dirty-ring tracking mechanism, together with an option to keep the good old dirty log around for pages that are dirtied by something other than a vcpu. - Switch to the relaxed parallel fault handling, using RCU to delay page table reclaim and giving better performance under load. - Relax the MTE ABI, allowing a VMM to use the MAP_SHARED mapping option, which multi-process VMMs such as crosvm rely on (see merge commit 382b5b87a97d: "Fix a number of issues with MTE, such as races on the tags being initialised vs the PG_mte_tagged flag as well as the lack of support for VM_SHARED when KVM is involved. Patches from Catalin Marinas and Peter Collingbourne"). - Merge the pKVM shadow vcpu state tracking that allows the hypervisor to have its own view of a vcpu, keeping that state private. - Add support for the PMUv3p5 architecture revision, bringing support for 64bit counters on systems that support it, and fix the no-quite-compliant CHAIN-ed counter support for the machines that actually exist out there. - Fix a handful of minor issues around 52bit VA/PA support (64kB pages only) as a prefix of the oncoming support for 4kB and 16kB pages. - Pick a small set of documentation and spelling fixes, because no good merge window would be complete without those. s390: - Second batch of the lazy destroy patches - First batch of KVM changes for kernel virtual != physical address support - Removal of a unused function x86: - Allow compiling out SMM support - Cleanup and documentation of SMM state save area format - Preserve interrupt shadow in SMM state save area - Respond to generic signals during slow page faults - Fixes and optimizations for the non-executable huge page errata fix. - Reprogram all performance counters on PMU filter change - Cleanups to Hyper-V emulation and tests - Process Hyper-V TLB flushes from a nested guest (i.e. from a L2 guest running on top of a L1 Hyper-V hypervisor) - Advertise several new Intel features - x86 Xen-for-KVM: - Allow the Xen runstate information to cross a page boundary - Allow XEN_RUNSTATE_UPDATE flag behaviour to be configured - Add support for 32-bit guests in SCHEDOP_poll - Notable x86 fixes and cleanups: - One-off fixes for various emulation flows (SGX, VMXON, NRIPS=0). - Reinstate IBPB on emulated VM-Exit that was incorrectly dropped a few years back when eliminating unnecessary barriers when switching between vmcs01 and vmcs02. - Clean up vmread_error_trampoline() to make it more obvious that params must be passed on the stack, even for x86-64. - Let userspace set all supported bits in MSR_IA32_FEAT_CTL irrespective of the current guest CPUID. - Fudge around a race with TSC refinement that results in KVM incorrectly thinking a guest needs TSC scaling when running on a CPU with a constant TSC, but no hardware-enumerated TSC frequency. - Advertise (on AMD) that the SMM_CTL MSR is not supported - Remove unnecessary exports Generic: - Support for responding to signals during page faults; introduces new FOLL_INTERRUPTIBLE flag that was reviewed by mm folks Selftests: - Fix an inverted check in the access tracking perf test, and restore support for asserting that there aren't too many idle pages when running on bare metal. - Fix build errors that occur in certain setups (unsure exactly what is unique about the problematic setup) due to glibc overriding static_assert() to a variant that requires a custom message. - Introduce actual atomics for clear/set_bit() in selftests - Add support for pinning vCPUs in dirty_log_perf_test. - Rename the so called "perf_util" framework to "memstress". - Add a lightweight psuedo RNG for guest use, and use it to randomize the access pattern and write vs. read percentage in the memstress tests. - Add a common ucall implementation; code dedup and pre-work for running SEV (and beyond) guests in selftests. - Provide a common constructor and arch hook, which will eventually be used by x86 to automatically select the right hypercall (AMD vs. Intel). - A bunch of added/enabled/fixed selftests for ARM64, covering memslots, breakpoints, stage-2 faults and access tracking. - x86-specific selftest changes: - Clean up x86's page table management. - Clean up and enhance the "smaller maxphyaddr" test, and add a related test to cover generic emulation failure. - Clean up the nEPT support checks. - Add X86_PROPERTY_* framework to retrieve multi-bit CPUID values. - Fix an ordering issue in the AMX test introduced by recent conversions to use kvm_cpu_has(), and harden the code to guard against similar bugs in the future. Anything that tiggers caching of KVM's supported CPUID, kvm_cpu_has() in this case, effectively hides opt-in XSAVE features if the caching occurs before the test opts in via prctl().

2022-12-15Revert "arm64: errata: Workaround possible Cortex-A715 [ESR|FAR]_ELx corruption"Will Deacon7-84/+0
This reverts commit 44ecda71fd8a70185c270f5914ac563827fe1d4c. All versions of this patch on the mailing list, including the version that ended up getting merged, have portions of code guarded by the non-existent CONFIG_ARM64_WORKAROUND_2645198 option. Although Anshuman says he tested the code with some additional debug changes [1], I'm hesitant to fix the CONFIG option and light up a bunch of code right before I (and others) disappear for the end of year holidays, during which time we won't be around to deal with any fallout. So revert the change for now. We can bring back a fixed, tested version for a later -rc when folks are thinking about things other than trees and turkeys.

Most of the work was done by me, some of it in collaboration with the distro and bootloader folks (GRUB, systemd-boot), where the main focus has been on removing pointless per-arch differences in the way EFI boots a Linux kernel. - Refactor the zboot code so that it incorporates all the EFI stub logic, rather than calling the decompressed kernel as a EFI app. - Add support for initrd= command line option to x86 mixed mode. - Allow initrd= to be used with arbitrary EFI accessible file systems instead of just the one the kernel itself was loaded from. - Move some x86-only handling and manipulation of the EFI memory map into arch/x86, as it is not used anywhere else. - More flexible handling of any random seeds provided by the boot environment (i.e., systemd-boot) so that it becomes available much earlier during the boot. - Allow improved arch-agnostic EFI support in loaders, by setting a uniform baseline of supported features, and adding a generic magic number to the DOS/PE header. This should allow loaders such as GRUB or systemd-boot to reduce the amount of arch-specific handling substantially. - (arm64) Run EFI runtime services from a dedicated stack, and use it to recover from synchronous exceptions that might occur in the firmware code. - (arm64) Ensure that we don't allocate memory outside of the 48-bit addressable physical range. - Make EFI pstore record size configurable - Add support for decoding CXL specific CPER records" * tag 'efi-next-for-v6.2' of git://git.kernel.org/pub/scm/linux/kernel/git/efi/efi: (43 commits) arm64: efi: Recover from synchronous exceptions occurring in firmware arm64: efi: Execute runtime services from a dedicated stack arm64: efi: Limit allocations to 48-bit addressable physical region efi: Put Linux specific magic number in the DOS header efi: libstub: Always enable initrd command line loader and bump version efi: stub: use random seed from EFI variable efi: vars: prohibit reading random seed variables efi: random: combine bootloader provided RNG seed with RNG protocol output efi/cper, cxl: Decode CXL Error Log efi/cper, cxl: Decode CXL Protocol Error Section efi: libstub: fix efi_load_initrd_dev_path() kernel-doc comment efi: x86: Move EFI runtime map sysfs code to arch/x86 efi: runtime-maps: Clarify purpose and enable by default for kexec efi: pstore: Add module parameter for setting the record size efi: xen: Set EFI_PARAVIRT for Xen dom0 boot on all architectures efi: memmap: Move manipulation routines into x86 arch tree efi: memmap: Move EFI fake memmap support into x86 arch tree efi: libstub: Undeprecate the command line initrd loader efi: libstub: Add mixed mode support to command line initrd loader efi: libstub: Permit mixed mode return types other than efi_status_t ...

git://git.kernel.org/pub/scm/linux/kernel/git/crng/random Pull random number generator updates from Jason Donenfeld: - Replace prandom_u32_max() and various open-coded variants of it, there is now a new family of functions that uses fast rejection sampling to choose properly uniformly random numbers within an interval: get_random_u32_below(ceil) - [0, ceil) get_random_u32_above(floor) - (floor, U32_MAX] get_random_u32_inclusive(floor, ceil) - [floor, ceil] Coccinelle was used to convert all current users of prandom_u32_max(), as well as many open-coded patterns, resulting in improvements throughout the tree. I'll have a "late" 6.1-rc1 pull for you that removes the now unused prandom_u32_max() function, just in case any other trees add a new use case of it that needs to converted. According to linux-next, there may be two trivial cases of prandom_u32_max() reintroductions that are fixable with a 's/.../.../'. So I'll have for you a final conversion patch doing that alongside the removal patch during the second week. This is a treewide change that touches many files throughout. - More consistent use of get_random_canary(). - Updates to comments, documentation, tests, headers, and simplification in configuration. - The arch_get_random*_early() abstraction was only used by arm64 and wasn't entirely useful, so this has been replaced by code that works in all relevant contexts. - The kernel will use and manage random seeds in non-volatile EFI variables, refreshing a variable with a fresh seed when the RNG is initialized. The RNG GUID namespace is then hidden from efivarfs to prevent accidental leakage. These changes are split into random.c infrastructure code used in the EFI subsystem, in this pull request, and related support inside of EFISTUB, in Ard's EFI tree. These are co-dependent for full functionality, but the order of merging doesn't matter. - Part of the infrastructure added for the EFI support is also used for an improvement to the way vsprintf initializes its siphash key, replacing an sleep loop wart. - The hardware RNG framework now always calls its correct random.c input function, add_hwgenerator_randomness(), rather than sometimes going through helpers better suited for other cases. - The add_latent_entropy() function has long been called from the fork handler, but is a no-op when the latent entropy gcc plugin isn't used, which is fine for the purposes of latent entropy. But it was missing out on the cycle counter that was also being mixed in beside the latent entropy variable. So now, if the latent entropy gcc plugin isn't enabled, add_latent_entropy() will expand to a call to add_device_randomness(NULL, 0), which adds a cycle counter, without the absent latent entropy variable. - The RNG is now reseeded from a delayed worker, rather than on demand when used. Always running from a worker allows it to make use of the CPU RNG on platforms like S390x, whose instructions are too slow to do so from interrupts. It also has the effect of adding in new inputs more frequently with more regularity, amounting to a long term transcript of random values. Plus, it helps a bit with the upcoming vDSO implementation (which isn't yet ready for 6.2). - The jitter entropy algorithm now tries to execute on many different CPUs, round-robining, in hopes of hitting even more memory latencies and other unpredictable effects. It also will mix in a cycle counter when the entropy timer fires, in addition to being mixed in from the main loop, to account more explicitly for fluctuations in that timer firing. And the state it touches is now kept within the same cache line, so that it's assured that the different execution contexts will cause latencies. * tag 'random-6.2-rc1-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/crng/random: (23 commits) random: include <linux/once.h> in the right header random: align entropy_timer_state to cache line random: mix in cycle counter when jitter timer fires random: spread out jitter callback to different CPUs random: remove extraneous period and add a missing one in comments efi: random: refresh non-volatile random seed when RNG is initialized vsprintf: initialize siphash key using notifier random: add back async readiness notifier random: reseed in delayed work rather than on-demand random: always mix cycle counter in add_latent_entropy() hw_random: use add_hwgenerator_randomness() for early entropy random: modernize documentation comment on get_random_bytes() random: adjust comment to account for removed function random: remove early archrandom abstraction random: use random.trust_{bootloader,cpu} command line option only stackprotector: actually use get_random_canary() stackprotector: move get_random_canary() into stackprotector.h treewide: use get_random_u32_inclusive() when possible treewide: use get_random_u32_{above,below}() instead of manual loop treewide: use get_random_u32_below() instead of deprecated function ...

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull timer updates from Thomas Gleixner: "Updates for timers, timekeeping and drivers: Core: - The timer_shutdown[_sync]() infrastructure: Tearing down timers can be tedious when there are circular dependencies to other things which need to be torn down. A prime example is timer and workqueue where the timer schedules work and the work arms the timer. What needs to prevented is that pending work which is drained via destroy_workqueue() does not rearm the previously shutdown timer. Nothing in that shutdown sequence relies on the timer being functional. The conclusion was that the semantics of timer_shutdown_sync() should be: - timer is not enqueued - timer callback is not running - timer cannot be rearmed Preventing the rearming of shutdown timers is done by discarding rearm attempts silently. A warning for the case that a rearm attempt of a shutdown timer is detected would not be really helpful because it's entirely unclear how it should be acted upon. The only way to address such a case is to add 'if (in_shutdown)' conditionals all over the place. This is error prone and in most cases of teardown not required all. - The real fix for the bluetooth HCI teardown based on timer_shutdown_sync(). A larger scale conversion to timer_shutdown_sync() is work in progress. - Consolidation of VDSO time namespace helper functions - Small fixes for timer and timerqueue Drivers: - Prevent integer overflow on the XGene-1 TVAL register which causes an never ending interrupt storm. - The usual set of new device tree bindings - Small fixes and improvements all over the place" * tag 'timers-core-2022-12-10' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (34 commits) dt-bindings: timer: renesas,cmt: Add r8a779g0 CMT support dt-bindings: timer: renesas,tmu: Add r8a779g0 support clocksource/drivers/arm_arch_timer: Use kstrtobool() instead of strtobool() clocksource/drivers/timer-ti-dm: Fix missing clk_disable_unprepare in dmtimer_systimer_init_clock() clocksource/drivers/timer-ti-dm: Clear settings on probe and free clocksource/drivers/timer-ti-dm: Make timer_get_irq static clocksource/drivers/timer-ti-dm: Fix warning for omap_timer_match clocksource/drivers/arm_arch_timer: Fix XGene-1 TVAL register math error clocksource/drivers/timer-npcm7xx: Enable timer 1 clock before use dt-bindings: timer: nuvoton,npcm7xx-timer: Allow specifying all clocks dt-bindings: timer: rockchip: Add rockchip,rk3128-timer clockevents: Repair kernel-doc for clockevent_delta2ns() clocksource/drivers/ingenic-ost: Define pm functions properly in platform_driver struct clocksource/drivers/sh_cmt: Access registers according to spec vdso/timens: Refactor copy-pasted find_timens_vvar_page() helper into one copy Bluetooth: hci_qca: Fix the teardown problem for real timers: Update the documentation to reflect on the new timer_shutdown() API timers: Provide timer_shutdown[_sync]() timers: Add shutdown mechanism to the internal functions timers: Split [try_to_]del_timer[_sync]() to prepare for shutdown mode ...

Pull ARM SoC DT updates from Arnd Bergmann: "The devicetree changes contain exactly 1000 non-merge changesets, including a number of new arm64 SoC variants from Qualcomm and Apple, as well as the Renesas r9a07g043f/u chip in both arm64 and riscv variants. While we have occasionally merged support for non-arm SoCs in the past, this is now the normal path for riscv devicetree files. The most notable changes, by SoC platform, are: - The Apple T6000 (M1 Pro), T6001 (M1 Max) and T6002 (M1 Ultra) chips now have initial support. This is particularly nice as I am typing this on a T6002 Mac Studio with only a small number of driver patches. - Qualcomm MSM8996 Pro (Snapdragon 821), SM6115 (Snapdragon 662), SM4250 (Snapdragon 460), SM6375 (Snapdragon 695), SDM670 (Snapdragon 670), MSM8976 (Snapdragon 652) and MSM8956 (Snapdragon 650) are all mobile phone chips that are closely related to others we already support. Adding those helps support more phones and we add several models from Sony (Xperia 10 IV, 5 IV, X, and X compact), OnePlus (One, 3, 3T, and Nord N100), Xiaomi (Poco F1, Mi6), Huawei (Watch) and Google (Pixel 3a). There are also new variants of the Herobrine and Trogdor chromebook motherboards. SA8540P is an automotive SoC used in the Qdrive-3 development platform - Rockchips gains no new SoC variants, but a lot of new boards: three mobile gaming systems based on RK3326 Odroid-Go/rg351 family, two more Anbernic gaming systems based on RK3566 and a number of other RK356x based single-board computers. - Renesas RZ/G2UL (r9a07g043) was already supported for arm64, but as the newly added RZ/Five is based on the same design, this now gets reorganized in order to share most of the dts description between the two and add the RZ/Five SMARC EVK board support. Aside from that, there are the usual changes all over the tree: - New boards on other platforms contain two ASpeed BMC users, two Broadcom based Wifi routers, Zyxel NSA310S NAS, the i.MX6 based Kobo Aura2 ebook reader, two i.MX8 based development boards, two Uniphier Pro5 development boards, the STM32MP1 testbench board from DHCOR, the TI K3 based BeagleBone AI-64 board, and the Mediatek Helio X10 based Sony Xperia M5 phone. - The Starfive JH7100 source gets reorganized in order to support the VisionFive V1 board. - Minor updates and cleanups for Intel SoCFPGA, Marvell PXA168, TI, ST, NXP, Apple, Broadcom, Juno, Marvell MVEBU, at91, nuvoton, Tegra, Mediatek, Renesas, Hisilicon, Allwinner, Samsung, ux500, spear, ...

git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu Pull RCU updates from Paul McKenney: - Documentation updates. This is the second in a series from an ongoing review of the RCU documentation. - Miscellaneous fixes. - Introduce a default-off Kconfig option that depends on RCU_NOCB_CPU that, on CPUs mentioned in the nohz_full or rcu_nocbs boot-argument CPU lists, causes call_rcu() to introduce delays. These delays result in significant power savings on nearly idle Android and ChromeOS systems. These savings range from a few percent to more than ten percent. This series also includes several commits that change call_rcu() to a new call_rcu_hurry() function that avoids these delays in a few cases, for example, where timely wakeups are required. Several of these are outside of RCU and thus have acks and reviews from the relevant maintainers. - Create an srcu_read_lock_nmisafe() and an srcu_read_unlock_nmisafe() for architectures that support NMIs, but which do not provide NMI-safe this_cpu_inc().

You name it, we got it, we probably broke it. - Pick a small set of documentation and spelling fixes, because no good merge window would be complete without those.

2022-12-08arm64: efi: Recover from synchronous exceptions occurring in firmwareArd Biesheuvel4-5/+61
Unlike x86, which has machinery to deal with page faults that occur during the execution of EFI runtime services, arm64 has nothing like that, and a synchronous exception raised by firmware code brings down the whole system. With more EFI based systems appearing that were not built to run Linux (such as the Windows-on-ARM laptops based on Qualcomm SOCs), as well as the introduction of PRM (platform specific firmware routines that are callable just like EFI runtime services), we are more likely to run into issues of this sort, and it is much more likely that we can identify and work around such issues if they don't bring down the system entirely. Since we already use a EFI runtime services call wrapper in assembler, we can quite easily add some code that captures the execution state at the point where the call is made, allowing us to revert to this state and proceed execution if the call triggered a synchronous exception. Given that the kernel and the firmware don't share any data structures that could end up in an indeterminate state, we can happily continue running, as long as we mark the EFI runtime services as unavailable from that point on.

2022-12-08arm64: efi: Execute runtime services from a dedicated stackArd Biesheuvel3-1/+42
With the introduction of PRMT in the ACPI subsystem, the EFI rts workqueue is no longer the only caller of efi_call_virt_pointer() in the kernel. This means the EFI runtime services lock is no longer sufficient to manage concurrent calls into firmware, but also that firmware calls may occur that are not marshalled via the workqueue mechanism, but originate directly from the caller context. For added robustness, and to ensure that the runtime services have 8 KiB of stack space available as per the EFI spec, introduce a spinlock protected EFI runtime stack of 8 KiB, where the spinlock also ensures serialization between the EFI rts workqueue (which itself serializes EFI runtime calls) and other callers of efi_call_virt_pointer(). While at it, use the stack pivot to avoid reloading the shadow call stack pointer from the ordinary stack, as doing so could produce a gadget to defeat it.

2022-12-08arm64: dts: apple: t6002: Fix GPU power domainsAsahi Lina1-0/+5
On t6002 (M1 Ultra), each die contains a self-contained GPU block. However, only the coprocessor and global management circuitry of the first die are used. This is what is represented by the "gpu" PS (the one in die1 is disabled). Nonetheless, this shared component drives the processing blocks in both dies, and therefore depends on the AFR fabric being powered up on both dies. Add an explicit dependency from the GPU block on die0 to AFR on die1, next to the existing die0 AFR dependency.

The UEFI spec does not mention or reason about the configured size of the virtual address space at all, but it does mention that all memory should be identity mapped using a page size of 4 KiB. This means that a LPA2 capable system that has any system memory outside of the 48-bit addressable physical range and follows the spec to the letter may serve page allocation requests from regions of memory that the kernel cannot access unless it was built with LPA2 support and enables it at runtime. So let's ensure that all page allocations are limited to the 48-bit range. Signed-off-by: Ard Biesheuvel <ardb@kernel.org>
