Roberto Sassu 020aae3ee5 ima: do not update security.ima if appraisal status is not INTEGRITY_PASS ... Commit b65a9cfc2c ("Untangling ima mess, part 2: deal with counters") moved the call of ima_file_check() from may_open() to do_filp_open() at a point where the file descriptor is already opened. This breaks the assumption made by IMA that file descriptors being closed belong to files whose access was granted by ima_file_check(). The consequence is that security.ima and security.evm are updated with good values, regardless of the current appraisal status. For example, if a file does not have security.ima, IMA will create it after opening the file for writing, even if access is denied. Access to the file will be allowed afterwards. Avoid this issue by checking the appraisal status before updating security.ima.
