efi: Lock down the kernel if booted in secure boot mode Based on an earlier patch by David Howells, who wrote the following description: > UEFI Secure Boot provides a mechanism for ensuring that the firmware will > only load signed bootloaders and kernels. Certain use cases may also > require that all kernel modules also be signed. Add a configuration option > that to lock down the kernel - which includes requiring validly signed > modules - if the kernel is secure-booted. Signed-off-by: Ben Hutchings <ben@decadent.org.uk> [Salvatore Bonaccorso: After fixing https://bugs.debian.org/956197 the help text for LOCK_DOWN_IN_EFI_SECURE_BOOT was adjusted to mention that lockdown is triggered in integrity mode (https://bugs.debian.org/1025417)] Signed-off-by: Salvatore Bonaccorso <carnil@debian.org> | 1 年前 | |
security: Add a static lockdown policy LSM While existing LSMs can be extended to handle lockdown policy, distributions generally want to be able to apply a straightforward static policy. This patch adds a simple LSM that can be configured to reject either integrity or all lockdown queries, and can be configured at runtime (through securityfs), boot time (via a kernel parameter) or build time (via a kconfig option). Based on initial code by David Howells.
