From 5a9196d715607f76d6b7d96a0970d6065335e62b Mon Sep 17 00:00:00 2001 From: Mimi Zohar Date: Tue, 22 Jul 2014 10:39:48 -0400 Subject: ima: add support for measuring and appraising firmware The "security: introduce kernel_fw_from_file hook" patch defined a new security hook to evaluate any loaded firmware that wasn't built into the kernel. This patch defines ima_fw_from_file(), which is called from the new security hook, to measure and/or appraise the loaded firmware's integrity.
