From 4238fad366a660cbc6499ca1ea4be42bd4d1ac5b Mon Sep 17 00:00:00 2001 From: Nayna Jain Date: Wed, 30 Oct 2019 23:31:27 -0400 Subject: powerpc/ima: Add support to initialize ima policy rules PowerNV systems use a Linux-based bootloader, which rely on the IMA subsystem to enforce different secure boot modes. Since the verification policy may differ based on the secure boot mode of the system, the policies must be defined at runtime. This patch implements arch-specific support to define IMA policy rules based on the runtime secure boot mode of the system. This patch provides arch-specific IMA policies if PPC_SECURE_BOOT config is enabled.
