Subject: [d-kernel] [PATCH v2 0/6] Lock down the kernel if booted in Secure Boot mode
Date: Wed, 27 May 2026 11:25:33 +0300
Message-ID: <20260527082539.2000966-1-egori@altlinux.org> (raw)

Данный набор патчей включает механизм kernel lockdown при загрузке
системы в режиме Secure Boot. При обнаружении активного Secure Boot
ядро автоматически переводится в режим lockdown.

В основу серии положен изначальный патчсет "security, efi: Add kernel
lockdown" за авторством David Howells. Использованы более актуальные
варианты соответствующих патчей, поддерживаемые в ядрах Fedora и Debian.

Список актуальных патчей из разных дистрибутивов доступен по ссылке
https://lore.altlinux.org/devel-kernel/b14cf8af-c95c-4733-8f89-155c0a5f11dd@altlinux.org/

Серия предназначена для веток 7.0 и 7.1.

David Howells (2):
  efi: Add an EFI_SECURE_BOOT flag to indicate secure boot mode
  efi: Lock down the kernel if booted in secure boot mode

Egor Ignatov (3):
  mtd: slram: Add the kernel lock down check
  security: lockdown: expose security_lock_kernel_down function
  config: Enable LOCK_DOWN_IN_EFI_SECURE_BOOT

Linn Crosetto (1):
  efi: determine and pass Secure Boot state via FDT
