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:

Commit b3b3f8186e attempted to fix a bug,
but didn't. The following patch should do it.

Currently audit2allow/sepolgen will create two identical gen_requires
block if you have allow rules and a role statement.
This patch fixes this problem.
