The block-stream command has traditionally used the 'base' parameter to indicate the image to copy the data from. This test checks that the 'base-node' parameter can also be used for the same purpose. Signed-off-by: NAlberto Garcia <berto@igalia.com> Signed-off-by: NKevin Wolf <kwolf@redhat.com>

The way to specify the node from which to copy data in the block-stream operation is by using the 'base' parameter. This parameter however takes a file name, not a node name. Since we want to be able to perform this operation using only node names, this patch adds a new 'base-node' parameter.

Quorum children are special in the sense that they're not directly attached to a block backend but they're not used as backing images either. However the intermediate block streaming code supports streaming to them. This is a test case for that scenario.

There's many tests that need Quorum support in order to run. At the moment each test implements its own check to see if Quorum is enabled.

This patch makes the 'device' parameter of the 'block-stream' command accept a node name that is not a root node. The presence of this feature can't be directly tested with introspection; soon we'll introduce a 'base-node' parameter whose presence can be checked for this purpose. In addition to that, operation blockers will be checked in all intermediate nodes between the top and the base node.

This makes sure that the image we are streaming into is open in read-write mode during the operation. Operation blockers are also set in all intermediate nodes, since they will be removed from the chain afterwards. Finally, this also unblocks the stream operation in backing files.

After a successful block-commit operation all nodes between top and base are removed from the backing chain, and top's overlay needs to be updated to point to base.

qmp_block_commit() checks for op blockers in the active and destination (base) images. However all nodes between top_bs and base are also involved, and they are removed from the chain afterwards. In addition to that, if top_bs is not the active layer then top_bs's overlay also needs to be checked because it's involved in the job (its backing image string needs to be updated to point to 'base').

When a block job is created on a certain BlockDriverState, operations are blocked there while the job exists. However, some block jobs may involve additional BDSs, which must be blocked separately when the job is created and unblocked manually afterwards. This patch adds block_job_add_bdrv(), that simplifies this process by keeping a list of BDSs that are involved in the specified block job.

When a BlockDriverState is about to be reopened it can trigger certain operations that need to write to disk. During this process a different block job can be woken up. If that block job completes and also needs to call bdrv_reopen() it can happen that it needs to do it on the same BlockDriverState that is still in the process of being reopened. This can have fatal consequences, like in this example: 1) Block job A starts and sleeps after a while. 2) Block job B starts and tries to reopen node1 (a qcow2 file). 3) Reopening node1 means flushing and replacing its qcow2 cache. 4) While the qcow2 cache is being flushed, job A wakes up. 5) Job A completes and reopens node1, replacing its cache. 6) Job B resumes, but the cache that was being flushed no longer exists. This patch splits the bdrv_drain_all() call to keep all block jobs paused during bdrv_reopen_multiple(), so that step 4 can never happen and the operation is safe. Note that this scenario can only happen if both bdrv_reopen() calls are made by block jobs on the same backing chain. Otherwise there's no chance that the same BlockDriverState appears in both reopen queues.

bdrv_drain_all() doesn't allow the caller to do anything after all pending requests have been completed but before block jobs are resumed. This patch splits bdrv_drain_all() into _begin() and _end() for that purpose. It also adds aio_{disable,enable}_external() calls to disable external clients in the meantime. An important restriction of this split is that no new block jobs or BlockDriverStates can be created between the bdrv_drain_all_begin() and bdrv_drain_all_end() calls. This is not a concern now because we'll only be using this in bdrv_reopen_multiple(), but it must be dealt with if we ever have other uses cases in the future.

If sent to the Secondary side, the Secondary side will run failover work, then takes over PVM's service work.
