From 05a351630b7463ce58668095f5683669c1295f65 Mon Sep 17 00:00:00 2001 From: Deven Bowers Date: Fri, 2 Aug 2024 23:08:17 -0700 Subject: ipe: add evaluation loop Introduce a core evaluation function in IPE that will be triggered by various security hooks (e.g., mmap, bprm_check, kexec). This function systematically assesses actions against the defined IPE policy, by iterating over rules specific to the action being taken. This critical addition enables IPE to enforce its security policies effectively, ensuring that actions intercepted by these hooks are scrutinized for policy compliance before they are allowed to proceed.
