I was looking into this dbus-broker audit message, which has the wrong audit type:
audit[422]: USER_AVC pid=422 uid=999 auid=4294967295 ses=4294967295
subj=system_u:system_r:system_dbusd_t msg='avc: received policyload notice
(seqno=2)
This is due to dbus-broker setting their avc log callback to send USER_AVC audit
messages for everything that comes to the libselinux log callback. I think the
right thing to do there is to change it to emit USER_SELINUX_ERR audit messages
if the log message is SELINUX_ERROR, otherwise log the message using their
regular method (stderr I think).
But the question became, why is the userspace AVC not simply emitting its own
USER_MAC_POLICY_LOAD audit message instead of sending a message to the log
callback?
Ok, I missed that there is a SELINUX_AVC log type and that's how the userspace
denial messages are sent out. How about adding SELINUX_POLICYLOAD and
SELINUX_ENFORCE log types so that callers can emit appropriate audit messages?
