From be39ffc2fec78ff80d50e4b7970e94a8b1583862 Mon Sep 17 00:00:00 2001 From: Roberto Sassu Date: Fri, 12 Sep 2014 19:35:53 +0200 Subject: ima: return an error code from ima_add_boot_aggregate() This patch modifies ima_add_boot_aggregate() to return an error code. This way we can determine if all the initialization procedures have been executed successfully.
