416 *Security note:
417 * The hardware protection mechanism works like this: Each device object that
418 * is subject to UAR doorbells (QP/SQ/CQ) gets a UAR ID (called uar_page in
419 * the device specification manual) upon its creation. Then upon doorbell,
420 * hardware fetches the object context for which the doorbell was rang, and
421 * validates that the UAR through which the DB was rang matches the UAR ID
422 * of the object.
423 * If no match the doorbell is silently ignored by the hardware. Of course,
424 * the user cannot ring a doorbell on a UAR that was not mapped to it.
425 * Now in devx, as the devx kernel does not manipulate the QP/SQ/CQ command
426 * mailboxes (except tagging them with UID), we expose to the user its UAR
427 * ID, so it can embed it in these objects in the expected specification
428 * format. So the only thing the user can do is hurt itself by creating a
429 * QP/SQ/CQ with a UAR ID other than his, and then in this case other users
430 * may ring a doorbell on its objects.
431 * The consequence of that will be that another user can schedule a QP/SQ
432 * of the buggy user for execution (just insert it to the hardware schedule
433 * queue or arm its CQ for event generation), no further harm is expected.
