ima: Log the same audit cause whenever a file has no signature
If the file doesn't have an xattr, ima_appraise_measurement sets cause to "missing-hash" while if there's an xattr but it's a digest instead of a signature it sets cause to "IMA-signature-required". Fix it by setting cause to "IMA-signature-required" in both cases. Signed-off-by: Thiago Jung Bauermann <bauerman@linux.vnet.ibm.com> Signed-off-by: Mimi Zohar <zohar@linux.vnet.ibm.com>
