Merge tag 'hardening-v6.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux
Pull hardening updates from Kees Cook: "One of the more voluminous set of changes is for adding the new __counted_by annotation[1] to gain run-time bounds checking of dynamically sized arrays with UBSan. - Add LKDTM test for stuck CPUs (Mark Rutland) - Improve LKDTM selftest behavior under UBSan (Ricardo CaƱuelo) - Refactor more 1-element arrays into flexible arrays (Gustavo A. R. Silva) - Analyze and replace strlcpy and strncpy uses (Justin Stitt, Azeem Shaikh) - Convert group_info.usage to refcount_t (Elena Reshetova) - Add __counted_by annotations (Kees Cook, Gustavo A. R. Silva) - Add Kconfig fragment for basic hardening options (Kees Cook, Lukas Bulwahn) - Fix randstruct GCC plugin performance mode to stay in groups (Kees Cook) - Fix strtomem() compile-time check for small sources (Kees Cook)" * tag 'hardening-v6.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux: (56 commits) hwmon: (acpi_power_meter) replace open-coded kmemdup_nul reset: Annotate struct reset_control_array with __counted_by kexec: Annotate struct crash_mem with __counted_by virtio_console: Annotate struct port_buffer with __counted_by ima: Add __counted_by for struct modsig and use struct_size() MAINTAINERS: Include stackleak paths in hardening entry string: Adjust strtomem() logic to allow for smaller sources hardening: x86: drop reference to removed config AMD_IOMMU_V2 randstruct: Fix gcc-plugin performance mode to stay in group mailbox: zynqmp: Annotate struct zynqmp_ipi_pdata with __counted_by drivers: thermal: tsens: Annotate struct tsens_priv with __counted_by irqchip/imx-intmux: Annotate struct intmux_data with __counted_by KVM: Annotate struct kvm_irq_routing_table with __counted_by virt: acrn: Annotate struct vm_memory_region_batch with __counted_by hwmon: Annotate struct gsc_hwmon_platform_data with __counted_by sparc: Annotate struct cpuinfo_tree with __counted_by isdn: kcapi: replace deprecated strncpy with strscpy_pad isdn: replace deprecated strncpy with strscpy NFS/flexfiles: Annotate struct nfs4_ff_layout_segment with __counted_by nfs41: Annotate struct nfs4_file_layout_dsaddr with __counted_by ...
