* block: Clarify error messages pertaining to 'node-name'Connor Kuehl2021-03-081-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some error messages contain ambiguous representations of the 'node-name' parameter. This can be particularly confusing when exchanging QMP messages (C = client, S = server): C: {"execute": "block_resize", "arguments": { "device": "my_file", "size": 26843545600 }} S: {"error": {"class": "GenericError", "desc": "Cannot find device=my_file nor node_name="}} ^^^^^^^^^ This error message suggests one could send a message with a key called 'node_name': C: {"execute": "block_resize", "arguments": { "node_name": "my_file", "size": 26843545600 }} ^^^^^^^^^ but using the underscore is actually incorrect, the parameter should be 'node-name': S: {"error": {"class": "GenericError", "desc": "Parameter 'node_name' is unexpected"}} This behavior was uncovered in bz1651437, but I ended up going down a rabbit hole looking for other areas where this miscommunication might occur and changing those accordingly as well.

* block: Improve some block-commit, block-stream error messagesMarkus Armbruster2020-12-101-6/+6
| | | | | | | | | | | | | | | | | | | | | block-commit defaults @base-node to the deepest backing image. When there is none, it fails with "Base 'NULL' not found". Improve to "There is no backing image". block-commit and block-stream reject a @base argument that doesn't resolve with "Base 'BASE' not found". Commit 6b33f3ae8b "qemu-img: Improve commit invalid base message" improved this message in qemu-img. Improve it here, too: "Can't find '%s' in the backing chain". QERR_BASE_NOT_FOUND is now unused.

* iotests: Specify explicit backing format where sensibleEric Blake2020-07-141-13/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are many existing qcow2 images that specify a backing file but no format. This has been the source of CVEs in the past, but has become more prominent of a problem now that libvirt has switched to -blockdev. With older -drive, at least the probing was always done by qemu (so the only risk of a changed format between successive boots of a guest was if qemu was upgraded and probed differently). But with newer -blockdev, libvirt must specify a format; if libvirt guesses raw where the image was formatted, this results in data corruption visible to the guest; conversely, if libvirt guesses qcow2 where qemu was using raw, this can result in potential security holes, so modern libvirt instead refuses to use images without explicit backing format. The change in libvirt to reject images without explicit backing format has pointed out that a number of tools have been far too reliant on probing in the past. It's time to set a better example in our own iotests of properly setting this parameter. iotest calls to create, rebase, and convert are all impacted to some degree. It's a bit annoying that we are inconsistent on command line - while all of those accept -o backing_file=...,backing_fmt=..., the shortcuts are different: create and rebase have -b and -F, while convert has -B but no -F. (amend has no shortcuts, but the previous patch just deprecated the use of amend to change backing chains).

| | | | | | | | | | | | | | | The python code already contains a possibility to skip tests if the corresponding driver is not available in the qemu binary - use it in more spots to avoid that the tests are failing if the driver has been disabled.

* block: Skip implicit nodes in query-block/blockstatsKevin Wolf2017-07-241-1/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commits 0db832f and 6cdbceb introduced the automatic insertion of filter nodes above the top layer of mirror and commit block jobs. The assumption made there was that since libvirt doesn't do node-level management of the block layer yet, it shouldn't be affected by added nodes. This is true as far as commands issued by libvirt are concerned. It only uses BlockBackend names to address nodes, so any operations it performs still operate on the root of the tree as intended. However, the assumption breaks down when you consider query commands, which return data for the wrong node now. These commands also return information on some child nodes (bs->file and/or bs->backing), which libvirt does make use of, and which refer to the wrong nodes, too. One of the consequences is that oVirt gets wrong information about the image size and stops the VM in response as long as a mirror or commit job is running: https://bugzilla.redhat.com/show_bug.cgi?id=1470634 This patch fixes the problem by hiding the implicit nodes created automatically by the mirror and commit block jobs in the output of query-block and BlockBackend-based query-blockstats as long as the user doesn't indicate that they are aware of those nodes by providing a node name for them in the QMP command to start the block job. The node-based commands query-named-block-nodes and query-blockstats with query-nodes=true still show all nodes, including implicit ones. This ensures that users that are capable of node-level management can still access the full information; users that only know BlockBackends won't use these commands.

* iotests: Omit length/offset test in 040 and 041Max Reitz2014-11-031-3/+1Star
| | | | | | | | | | | | | | | | | | | As of a follow-up patch to this one, the length of a mirror block job will no longer directly depend on the size of the block device; therefore, drop these checks from this test. Instead, just check whether the final offset equals the block job length. As 041 uses the wait_until_completed function from iotests.py, the same applies there as well which in turn affects tests 030, 055 and 056. On the other hand, a block job's length does not have to be related to the length of the image file in the first place, so that check was questionable anyway.
