2018-03-09iotests: Tweak 030 in order to trigger a race condition with parallel jobsAlberto Garcia
This patch tweaks TestParallelOps in iotest 030 so it allocates data in smaller regions (256KB/512KB instead of 512KB/1MB) and the block-stream job in test_stream_commit() only needs to copy data that is at the very end of the image. This way when the block-stream job is awakened it will finish right away without any chance of being stopped by block_job_sleep_ns(). This triggers the bug that was fixed by 3d5d319e1221082974711af1d09d82f and 1a63a907507fbbcfaee3f622907ec24 and is therefore a more useful test case for parallel block jobs. After this patch the aforementiond bug can also be reproduced with the test_stream_parallel() test case. Since with this change the stream job in test_stream_commit() finishes early, this patch introduces a similar test case where both jobs are slowed down so they can actually run in parallel.

2018-03-09iotests: Skip test for ENOMEM errorFam Zheng
The AFL image is to exercise the code validating image size, which doesn't work on 32 bit or when out of memory (there is a large allocation before the interesting point). So check that and skip the test, instead of faking the result.

2018-03-09qcow2: Use visitor for options in qcow2_create()Kevin Wolf
Instead of manually creating the BlockdevCreateOptions object, use a visitor to parse the given options into the QAPI object. This involves translation from the old command line syntax to the syntax mandated by the QAPI schema. Option names are still checked against qcow2_create_opts, so only the old option names are allowed on the command line, even if they are translated in qcow2_create(). In contrast, new option values are optionally recognised besides the old values: 'compat' accepts 'v2'/'v3' as an alias for '0.10'/'1.1', and 'encrypt.format' accepts 'qcow' as an alias for 'aes' now.

2018-03-09qcow2: Generalize validate_table_offset() into qcow2_validate_table()Alberto Garcia
This function checks that the offset and size of a table are valid. While the offset checks are fine, the size check is too generic, since it only verifies that the total size in bytes fits in a 64-bit integer. In practice all tables used in qcow2 have much smaller size limits, so the size needs to be checked again for each table using its actual limit. This patch generalizes this function by allowing the caller to specify the maximum size for that table. In addition to that it allows passing an Error variable. The function is also renamed and made public since we're going to use it in other parts of the code.

2018-01-23qemu-iotests: Fix locking issue in 102Max Reitz
102 truncates a qcow2 file (the raw file) on purpose while a VM is running. However, image locking will usually prevent exactly this. The fact that most people have not noticed until now (I suppose you may have seen sporadic failures, but not taken them too seriously, like me) further shows that this truncation is actually not really done concurrently, but that the VM is still starting up by this point and has not yet opened the image. Remedy this by waiting for the monitor shell to appear before the qemu-img invocation so we know the VM is up.
