From 219a3e8676f3132d27b530c7d2d6bcab89536b57 Mon Sep 17 00:00:00 2001 From: Kairui Song Date: Mon, 21 Jan 2019 17:59:28 +0800 Subject: integrity, KEYS: add a reference to platform keyring commit 9dc92c45177a ("integrity: Define a trusted platform keyring") introduced a .platform keyring for storing preboot keys, used for verifying kernel image signatures. Currently only IMA-appraisal is able to use the keyring to verify kernel images that have their signature stored in xattr. This patch exposes the .platform keyring, making it accessible for verifying PE signed kernel images as well.
