ima: added policy support for 'security.ima' type
The 'security.ima' extended attribute may contain either the file data's hash or a digital signature. This patch adds support for requiring a specific extended attribute type. It extends the IMA policy with a new keyword 'appraise_type=imasig'. (Default is hash.) Changelog v2: - Fixed Documentation/ABI/testing/ima_policy option syntax Changelog v1: - Differentiate between 'required' vs. 'actual' extended attribute Signed-off-by: Dmitry Kasatkin <dmitry.kasatkin@intel.com> Signed-off-by: Mimi Zohar <zohar@linux.vnet.ibm.com>
