Subject: [PATCH v2 0/2] add ima_arch support for ARM64
Date: Wed, 14 Oct 2020 18:40:30 +0800 [thread overview]
Message-ID: <20201014104032.9776-1-clin@suse.com> (raw)
Add IMA arch dependent support for ARM64. Some IMA functions can check
arch-specific status before running. For example, the ima_load_data
function or the boot param "ima_appraise=" should not be executed when
UEFI secure boot is enabled. We want to fill the gap in order to complete
the IMA support on ARM64.
Changes in v2:
- Separate get_sb_mode() from x86 so all EFI-based architectures can reuse
the same function.
- Refactor arch/arm64/kernel/ima_arch.c based on Ard's patch[1].
Test platforms:
- QEMU [aarch64-virt] + EDK2/OVMF
- NXP LX2160A-RDB + EDK2
