From 24c9ae23bdfa0642228e747849dd052fd4295c6c Mon Sep 17 00:00:00 2001 From: Roberto Sassu Date: Tue, 8 Jun 2021 14:31:21 +0200 Subject: ima: Set correct casting types The code expects that the values being parsed from a buffer when the ima_canonical_fmt global variable is true are in little endian. Thus, this patch sets the casting types accordingly.
