Originally audit2allow used the avc: allowed message generated by auditallow statement for load_policy to identify policy reloads. Later it was switched to use the MAC_POLICY_LOAD events generated by the audit framework. Those events should still get logged via printk if auditd is not running, but it appears that the code (audit_printk_skb) will then log the type= field as an integer rather than a string, and audit2allow/sepolgen only looks for the string MAC_POLICY_LOAD. So I suspect that this would be resolved by modifying sepolgen/audit.py to also match on type=1403 for load messages. Try this: diff --git a/sepolgen/src/sepolgen/audit.py b/sepolgen/src/sepolgen/audit.py index 4717dae..efcc40d 100644 --- a/sepolgen/src/sepolgen/audit.py +++ b/sepolgen/src/sepolgen/audit.py @@ -314,7 +314,7 @@ class AuditParser: elif i == "security_compute_sid:": msg = ComputeSidMessage(line) found = True - elif i == "type=MAC_POLICY_LOAD": + elif i == "type=MAC_POLICY_LOAD" or i == "type=1403": msg = PolicyLoadMessage(line) found = True elif i == "type=AVC_PATH": -- Stephen Smalley National Security Agency -- This message was distributed to subscribers of the selinux mailing list.
