CAP_AUDIT_WRITE is needed, but not CAP_AUDIT_CONTROL, which is needed to
set the loginuid. Of course, an LSM could check at
security_netlink_send whether the login_uid in the payload is the same
as the real loginuid. Otherwise, we're wasting a (very precious)
capability bit.
In either case, have we decided we don't want it in the netlink
credentials after all?
thanks,
