ima: audit log hashes
This adds an 'audit' policy action which audit logs file measurements. Changelog v6: - use new action flag handling (Dmitry Kasatkin). - removed whitespace (Mimi) Changelog v5: - use audit_log_untrustedstring. Changelog v4: - cleanup digest -> hash conversion. - use filename rather than d_path in ima_audit_measurement. Changelog v3: - Use newly exported audit_log_task_info for logging pid/ppid/uid/etc. - Update the ima_policy ABI documentation. Changelog v2: - Use 'audit' action rather than 'measure_and_audit' to permit auditing in the absence of measuring.. Changelog v1: - Initial posting.
