From 6191706246de99ff2fac4b6f157f20205a0943cd Mon Sep 17 00:00:00 2001 From: Nayna Jain Date: Tue, 9 Oct 2018 23:00:36 +0530 Subject: ima: add support for arch specific policies Builtin IMA policies can be enabled on the boot command line, and replaced with a custom policy, normally during early boot in the initramfs. Build time IMA policy rules were recently added. These rules are automatically enabled on boot and persist after loading a custom policy. There is a need for yet another type of policy, an architecture specific policy, which is derived at runtime during kernel boot, based on the runtime secure boot flags. Like the build time policy rules, these rules persist after loading a custom policy. This patch adds support for loading an architecture specific IMA policy.
