Summary in the tag, but the big two features are support for Branch Target Identification and Clang's Shadow Call stack. The latter is currently arm64-only, but the high-level parts are all in core code so it could easily be adopted by other architectures pending toolchain support. Please note that this includes the x86/asm branch from -tip due to a dependency from the BTI code on the new 'CONFIG_ARCH_USE_SYM_ANNOTATIONS' option. I've left that in the diffstat below because it's only two commits. Cheers, Will --->8 The following changes since commit 6a8b55ed4056ea5559ebe4f6a4b247f627870d4c: Linux 5.7-rc3 (2020-04-26 13:51:02 -0700) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux.git tags/arm64-upstream for you to fetch changes up to 082af5ec5080b028f7d0846a6c27cbb87f288205: Merge branch 'for-next/scs' into for-next/core (2020-05-28 18:03:40 +0100) ---------------------------------------------------------------- arm64 updates for 5.8 - Branch Target Identification (BTI) * Support for ARMv8.5-BTI in both user- and kernel-space. This allows branch targets to limit the types of branch from which they can be called and additionally prevents branching to arbitrary code, although kernel support requires a very recent toolchain. * Function annotation via SYM_FUNC_START() so that assembly functions are wrapped with the relevant "landing pad" instructions. * BPF and vDSO updates to use the new instructions. * Addition of a new HWCAP and exposure of BTI capability to userspace via ID register emulation, along with ELF loader support for the BTI feature in .note.gnu.property. * Non-critical fixes to CFI unwind annotations in the sigreturn trampoline. - Shadow Call Stack (SCS) * Support for Clang's Shadow Call Stack feature, which reserves platform register x18 to point at a separate stack for each task that holds only return addresses. This protects function return control flow from buffer overruns on the main stack. * Save/restore of x18 across problematic boundaries (user-mode, hypervisor, EFI, suspend, etc). * Core support for SCS, should other architectures want to use it too. * SCS overflow checking on context-switch as part of the existing stack limit check if CONFIG_SCHED_STACK_END_CHECK=y. - CPU feature detection * Removed numerous "SANITY CHECK" errors when running on a system with mismatched AArch32 support at EL1. This is primarily a concern for KVM, which disabled support for 32-bit guests on such a system. * Addition of new ID registers and fields as the architecture has been extended. - Perf and PMU drivers * Minor fixes and cleanups to system PMU drivers. - Hardware errata * Unify KVM workarounds for VHE and nVHE configurations. * Sort vendor errata entries in Kconfig. - Secure Monitor Call Calling Convention (SMCCC) * Update to the latest specification from Arm (v1.2). * Allow PSCI code to query the SMCCC version. - Software Delegated Exception Interface (SDEI) * Unexport a bunch of unused symbols. * Minor fixes to handling of firmware data. - Pointer authentication * Add support for dumping the kernel PAC mask in vmcoreinfo so that the stack can be unwound by tools such as kdump. * Simplification of key initialisation during CPU bringup. - BPF backend * Improve immediate generation for logical and add/sub instructions. - vDSO - Minor fixes to the linker flags for consistency with other architectures and support for LLVM's unwinder. - Clean up logic to initialise and map the vDSO into userspace. - ACPI - Work around for an ambiguity in the IORT specification relating to the "num_ids" field. - Support _DMA method for all named components rather than only PCIe root complexes. - Minor other IORT-related fixes. - Miscellaneous * Initialise debug traps early for KGDB and fix KDB cacheflushing deadlock. * Minor tweaks to early boot state (documentation update, set TEXT_OFFSET to 0x0, increase alignment of PE/COFF sections). * Refactoring and cleanup
