- Set the LoaderDevicePartUUID EFI variable from the stub to help systemd discover the file system layout when booting straight into Linux without GRUB or systemd-boot (Vincent Mailhol) - Some GUID deduplication work from Vincent - Remove pointless UTF16->UTF8 and vice versa conversions from the stub, including some prerequisite work on the x86 decompressor to accommodate that - Some kmap() -> kmap_local_page() conversions in the capsule loader - Add a runtime control to en/disable EFI runtime services so that PREEMPT_RT systems can enable them as needed - Add a 'nostatfs' mount option to efivarfs so that the cost of querying the EFI variable store (which is already rate limited) can be avoided entirely on systems where it is disproportionately costly - Rework the EFI libstub Makefile to align x86 with other architectures, and inherit/adapt the global CFLAGS variable rather than reconstruct it from scratch - Constify attributes of statically allocated sysfs nodes - Avoid register x18 when building the arm64 EFI stub, in order to comply with the UEFI spec, and to permit it to execute in a context where x18 is special - Preserve the physical addresses of all EFI config tables that may be of interest to an incoming kexec kernel - Add some LKDTM tests for EFI runtime crashes where the faulting address is inside a EFI memory region - Other minor bug fixes and cosmetic cleanups -----BEGIN PGP SIGNATURE----- iHUEABYKAB0WIQQQm/3uucuRGn1Dmh0wbglWLn0tXAUCatSJtAAKCRAwbglWLn0t XEvXAQCpluirdoc3LaABTQUceGfFmM9EeETcB8FMuQv5+ATo8gEAy536vpGMlosG l3dwbsdEHBTGK0bvpViOqOelNH/5xQs= =3fkP -----END PGP SIGNATURE----- Merge tag 'efi-next-for-v7.4' of git://git.kernel.org/pub/scm/linux/kernel/git/efi/efi Pull EFI updates from Ard Biesheuvel: - Set the LoaderDevicePartUUID EFI variable from the stub to help systemd discover the file system layout when booting straight into Linux without GRUB or systemd-boot (Vincent Mailhol) - Some GUID deduplication work from Vincent - Remove pointless UTF16->UTF8 and vice versa conversions from the stub - Some kmap() -> kmap_local_page() conversions in the capsule loader - Add a runtime control to en/disable EFI runtime services so that PREEMPT_RT systems can enable them as needed - Add a 'nostatfs' mount option to efivarfs so that the cost of querying the EFI variable store (which is already rate limited) can be avoided entirely on systems where it is disproportionately costly - Rework the EFI libstub Makefile to align x86 with other architectures, and inherit/adapt the global CFLAGS variable rather than reconstruct it from scratch - Constify attributes of statically allocated sysfs nodes - Avoid register x18 when building the arm64 EFI stub, in order to comply with the UEFI spec, and to permit it to execute in a context where x18 is special - Preserve the physical addresses of all EFI config tables that may be of interest to an incoming kexec kernel - Add some LKDTM tests for EFI runtime crashes where the faulting address is inside a EFI memory region - Other minor bug fixes and cosmetic cleanups * tag 'efi-next-for-v7.4' of git://git.kernel.org/pub/scm/linux/kernel/git/efi/efi: (35 commits) lkdtm: Add more EFI runtime tests efi: Initialize all configuration table addresses to EFI_INVALID_TABLE_ADDR efi: Retain the address of the LINUX_EFI_MEMRESERVE table efi/libstub: Don't replace an existing LINUX_EFI_MEMRESERVE table efi/runtime-wrappers: Don't park the worker after a recovered firmware fault efi: Use sysfs_emit() not sprintf() to generate sysfs file contents efi: Constify sysfs attributes efi/libstub: Disable kernel stack erasing in the common flags efi/libstub: Build the x86 stub from KBUILD_CFLAGS efi/libstub: Declare the x86 stub's assembly entry points efi/libstub: arm64: Don't use the platform register x18 efi/libstub: Free cmdline_ptr in efi_pe_entry efi/riscv: libstub: Don't set image_size in handle_kernel_image() efi/libstub: Fix error unwind freeing fdt in allocate_new_fdt_and_exit_boot() efivarfs: add nostatfs mount option to skip QueryVariableInfo() efi/libstub: add initial Boot Loader Interface support efi/libstub: Add efi_snprintf() to construct wide strings efi/libstub: Add support for printing human readable GUIDs efi/libstub: Output UTF-16 directly from vsnprintf() efi/libstub: Avoid efi_puts() for compile time constant strings ... |
