Thanks, Amir. "mutext_init(&iint->mutex); moved, but the status initialization lines 161-166 were dropped. They're needed by IMA- appraisal for signature verification.
iint->ima_file_status = INTEGRITY_UNKNOWN; iint->ima_mmap_status = INTEGRITY_UNKNOWN; iint->ima_bprm_status = INTEGRITY_UNKNOWN; iint->ima_read_status = INTEGRITY_UNKNOWN; iint->ima_creds_status = INTEGRITY_UNKNOWN; iint->evm_status = INTEGRITY_UNKNOWN;
