In preparation of QAPI-fying VDI image creation, we have to create a BlockdevCreateOptionsVdi type which is received by a (future) vdi_co_create(). vdi_co_create_opts() now converts the QemuOpts object into such a BlockdevCreateOptionsVdi object. The protocol-layer file is still created in vdi_co_do_create() (and BlockdevCreateOptionsVdi.file is set to an empty string), but that will be addressed by a follow-up patch. Note that cluster-size is not part of the QAPI schema because it is not supported by default. Signed-off-by: NMax Reitz <mreitz@redhat.com> Signed-off-by: NKevin Wolf <kwolf@redhat.com>

The .bdrv_getlength implementation of the crypto block driver asserted that the payload offset isn't after EOF. This is an invalid assertion to make as the image file could be corrupted. Instead, check it and return -EIO if the file is too small for the payload offset. Zero length images are fine, so trigger -EIO only on offset > len, not on offset >= len as the assertion did before.

Everything that refers to the protocol layer or QemuOpts is moved out of block_crypto_create_generic(), so that the remaining function is suitable to be called by a .bdrv_co_create implementation. LUKS is the only driver that actually implements the old interface, and we don't intend to use it in any new drivers, so put the moved out code directly into a LUKS function rather than creating a generic intermediate one.

Instead of automatically transitioning from PENDING to CONCLUDED, gate the .prepare() and .commit() phases behind an explicit acknowledgement provided by the QMP monitor if auto_finalize = false has been requested. This allows us to perform graph changes in prepare and/or commit so that graph changes do not occur autonomously without knowledge of the controlling management layer. Transactions that have reached the "PENDING" state together can all be moved to invoke their finalization methods by issuing block_job_finalize to any one job in the transaction. Jobs in a transaction with mixed job->auto_finalize settings will all remain stuck in the "PENDING" state, as if the entire transaction was specified with auto_finalize = false. Jobs that specified auto_finalize = true, however, will still not emit the PENDING event. Signed-off-by: NJohn Snow <jsnow@redhat.com> Signed-off-by: NKevin Wolf <kwolf@redhat.com>

For jobs utilizing the new manual workflow, we intend to prohibit them from modifying the block graph until the management layer provides an explicit ACK via block-job-finalize to move the process forward. To distinguish this runstate from "ready" or "waiting," we add a new "pending" event and status. For now, the transition from PENDING to CONCLUDED/ABORTING is automatic, but a future commit will add the explicit block-job-finalize step. Transitions: Waiting -> Pending: Normal transition.

For jobs that are stuck waiting on others in a transaction, it would be nice to know that they are no longer "running" in that sense, but instead are waiting on other jobs in the transaction. Jobs that are "waiting" in this sense cannot be meaningfully altered any longer as they have left their running loop. The only meaningful user verb for jobs in this state is "cancel," which will cancel the whole transaction, too. Transitions: Running -> Waiting: Normal transition. Ready -> Waiting: Normal transition. Waiting -> Aborting: Transactional cancellation. Waiting -> Concluded: Normal transition.

Some jobs upon finalization may need to perform some work that can still fail. If these jobs are part of a transaction, it's important that these callbacks fail the entire transaction. We allow for a new callback in addition to commit/abort/clean that allows us the opportunity to have fairly late-breaking failures in the transactional process. The expected flow is: - All jobs in a transaction converge to the PENDING state, added in a forthcoming commit. - Upon being finalized, either automatically or explicitly by the user, jobs prepare to complete. - If any job fails preparation, all jobs call .abort. - Otherwise, they succeed and call .commit.

Presently, even if a job is canceled post-completion as a result of a failing peer in a transaction, it will still call .commit because nothing has updated or changed its return code. The reason why this does not cause problems currently is because backup's implementation of .commit checks for cancellation itself. I'd like to simplify this contract: (1) Abort is called if the job/transaction fails (2) Commit is called if the job/transaction succeeds To this end: A job's return code, if 0, will be forcibly set as -ECANCELED if that job has already concluded. Remove the now redundant check in the backup job implementation. We need to check for cancellation in both block_job_completed AND block_job_completed_single, because jobs may be cancelled between those two calls; for instance in transactions. This also necessitates an ABORTING -> ABORTING transition to be allowed. The check in block_job_completed could be removed, but there's no point in starting to attempt to succeed a transaction that we know in advance will fail. This does NOT affect mirror jobs that are "canceled" during their synchronous phase. The mirror job itself forcibly sets the canceled property to false prior to ceding control, so such cases will invoke the "commit" callback.

For jobs that have reached their CONCLUDED state, prior to having their last reference put down (meaning jobs that have completed successfully, unsuccessfully, or have been canceled), allow the user to dismiss the job's lingering status report via block-job-dismiss. This gives management APIs the chance to conclusively determine if a job failed or succeeded, even if the event broadcast was missed. Note: block_job_do_dismiss and block_job_decommission happen to do exactly the same thing, but they're called from different semantic contexts, so both aliases are kept to improve readability. Note 2: Don't worry about the 0x04 flag definition for AUTO_DISMISS, she has a friend coming in a future patch to fill the hole where 0x02 is. Verbs: Dismiss: operates on CONCLUDED jobs only.

Add a new state that specifically demarcates when we begin to permanently demolish a job after it has performed all work. This makes the transition explicit in the STM table and highlights conditions under which a job may be demolished. Alongside this state, add a new helper command "block_job_decommission", which transitions to the NULL state and puts down our implicit reference. This separates instances in the code for "block_job_unref" which merely undo a matching "block_job_ref" with instances intended to initiate the full destruction of the object. This decommission action also sets a number of fields to make sure that block internals or external users that are holding a reference to a job to see when it "finishes" are convinced that the job object is "done." This is necessary, for instance, to do a block_job_cancel_sync on a created object which will not make any progress. Now, all jobs must go through block_job_decommission prior to being freed, giving us start-to-finish state machine coverage for jobs. Transitions: Created -> Null: Early failure event before the job is started Concluded -> Null: Standard transition. Verbs: None.

Add a new state ABORTING. This makes transitions from normative states to error states explicit in the STM, and serves as a disambiguation for which states may complete normally when normal end-states (CONCLUDED) are added in future commits. Notably, Paused/Standby jobs do not transition directly to aborting, as they must wake up first and cooperate in their cancellation.

Which commands ("verbs") are appropriate for jobs in which state is also somewhat burdensome to keep track of. As of this commit, it looks rather useless, but begins to look more interesting the more states we add to the STM table. A recurring theme is that no verb will apply to an 'undefined' job. Further, it's not presently possible to restrict the "pause" or "resume" verbs any more than they are in this commit because of the asynchronous nature of how jobs enter the PAUSED state; justifications for some seemingly erroneous applications are given below. ===== Verbs ===== Cancel: Any state except undefined. Pause: Any state except undefined; 'created': Requests that the job pauses as it starts. 'running': Normal usage. (PAUSED) 'paused': The job may be paused for internal reasons, but the user may wish to force an indefinite user-pause, so this is allowed. 'ready': Normal usage. (STANDBY) 'standby': Same logic as above. Resume: Any state except undefined; 'created': Will lift a user's pause-on-start request. 'running': Will lift a pause request before it takes effect. 'paused': Normal usage. 'ready': Will lift a pause request before it takes effect. 'standby': Normal usage. Set-speed: Any state except undefined, though ready may not be meaningful. Complete: Only a 'ready' job may accept a complete request. ======= Changes ======= (1) To facilitate "nice" error checking, all five major block-job verb interfaces in blockjob.c now support an errp parameter: - block_job_user_cancel is added as a new interface. - block_job_user_pause gains an errp paramter - block_job_user_resume gains an errp parameter - block_job_set_speed already had an errp parameter. - block_job_complete already had an errp parameter. (2) block-job-pause and block-job-resume will no longer no-op when trying to pause an already paused job, or trying to resume a job that isn't paused. These functions will now report that they did not perform the action requested because it was not possible. iotests have been adjusted to address this new behavior. (3) block-job-complete doesn't worry about checking !block_job_started, because the permission table guards against this. (4) test-bdrv-drain's job implementation needs to announce that it is 'ready' now, in order to be completed.

The state transition table has mostly been implied. We're about to make it a bit more complex, so let's make the STM explicit instead. Perform state transitions with a function that for now just asserts the transition is appropriate. Transitions: Undefined -> Created: During job initialization. Created -> Running: Once the job is started. Jobs cannot transition from "Created" to "Paused" directly, but will instead synchronously transition to running to paused immediately. Running -> Paused: Normal workflow for pauses. Running -> Ready: Normal workflow for jobs reaching their sync point. (e.g. mirror) Ready -> Standby: Normal workflow for pausing ready jobs. Paused -> Running: Normal resume. Standby -> Ready: Resume of a Standby job. +---------+ |UNDEFINED| +--+------+ | +--v----+ |CREATED| +--+----+ | +--v----+ +------+ |RUNNING<----->PAUSED| +--+----+ +------+ | +--v--+ +-------+ |READY<------->STANDBY| +-----+ +-------+ Notably, there is no state presently defined as of this commit that deals with a job after the "running" or "ready" states, so this table will be adjusted alongside the commits that introduce those states.

We're about to add several new states, and booleans are becoming unwieldly and difficult to reason about. It would help to have a more explicit bookkeeping of the state of blockjobs. To this end, add a new "status" field and add our existing states in a redundant manner alongside the bools they are replacing: UNDEFINED: Placeholder, default state. Not currently visible to QMP unless changes occur in the future to allow creating jobs without starting them via QMP. CREATED: replaces !!job->co && paused && !busy RUNNING: replaces effectively (!paused && busy) PAUSED: Nearly redundant with info->paused, which shows pause_count. This reports the actual status of the job, which almost always matches the paused request status. It differs in that it is strictly only true when the job has actually gone dormant. READY: replaces job->ready. STANDBY: Paused, but job->ready is true. New state additions in coming commits will not be quite so redundant: WAITING: Waiting on transaction. This job has finished all the work it can until the transaction converges, fails, or is canceled. PENDING: Pending authorization from user. This job has finished all the work it can until the job or transaction is finalized via block_job_finalize. This implies the transaction has converged and left the WAITING phase. ABORTING: Job has encountered an error condition and is in the process of aborting. CONCLUDED: Job has ceased all operations and has a return code available for query and may be dismissed via block_job_dismiss. NULL: Job has been dismissed and (should) be destroyed. Should never be visible to QMP. Some of these states appear somewhat superfluous, but it helps define the expected flow of a job; so some of the states wind up being synchronous empty transitions. Importantly, jobs can be in only one of these states at any given time, which helps code and external users alike reason about the current condition of a job unambiguously.
