block: qemu-iotests 085 - live snapshots tests This adds tests for live snapshots, both through the single snapshot command, and the transaction group snapshot command. The snapshots are done through the QMP interface, using the following commands for snapshots: Single snapshot: { 'execute': 'blockdev-snapshot-sync', 'arguments': { 'device': 'virtio0', 'snapshot-file':'...', 'format': 'qcow2' } }" Group snapshot: { 'execute': 'transaction', 'arguments': {'actions': [ { 'type': 'blockdev-snapshot-sync', 'data' : { 'device': 'virtio0', 'snapshot-file': '...' } }, { 'type': 'blockdev-snapshot-sync', 'data' : { 'device': 'virtio1', 'snapshot-file': '...' } } ] } } Signed-off-by: Jeff Cody <jcody@redhat.com> Reviewed-by: Benoit Canet <benoit@irqsave.net> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

iotests: Include QMP input in .out files We generally include relevant HMP input in .out files, by virtue of the fact that HMP echoes its input. But QMP does not, so we have to explicitly inject it in the output stream (appropriately filtered to keep the tests passing), in order to make it easier to read .out files to see what behavior is being tested (especially true where the output file is a sequence of {'return': {}}).

iotests: Fix _send_qemu_cmd with bash 5.1 With bash 5.1, the output of the following script changes: a=("double space") a=${a[@]:0:1} echo "$a" from "double space" to "double space", i.e. all white space is preserved as-is. This is probably what we actually want here (judging from the "...to accommodate pathnames with spaces" comment), but before 5.1, we would have to quote the ${} slice to get the same behavior. In any case, without quoting, the reference output of many iotests is different between bash 5.1 and pre-5.1, which is not very good. The output of 5.1 is what we want, so whatever we do to get pre-5.1 to the same result, it means we have to fix the reference output of basically all tests that invoke _send_qemu_cmd (except the ones that only use single spaces in the commands they invoke). Instead of quoting the ${} slice (cmd="${$@: 1:...}"), we can also just not use array slicing and replace the whole thing with a simple "cmd=$1; shift", which works because all callers quote the whole $cmd argument anyway.

block: Clarify error messages pertaining to 'node-name' 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.

Instead of quoting the ${} slice (cmd="${$@: 1:...}"), we can also just not use array slicing and replace the whole thing with a simple "cmd=$1; shift", which works because all callers quote the whole $cmd argument anyway.

=== Create a couple of snapshots using blockdev-snapshot ===
iotests: Specify explicit backing format where sensible 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).

iotests: Specify explicit backing format where sensible 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).

block: Relax restrictions for blockdev-snapshot blockdev-snapshot returned an error if the overlay was already in use, which it defined as having any BlockBackend parent. This is in fact both too strict (some parents can tolerate the change of visible data caused by attaching a backing file) and too loose (some non-BlockBackend parents may not be happy with it). One important use case that is prevented by the too strict check is live storage migration with blockdev-mirror. Here, the target node is usually opened without a backing file so that the active layer is mirrored while its backing chain can be copied in the background. The backing chain should be attached to the mirror target node when finalising the job, just before switching the users of the source node to the new copy (at which point the mirror job still has a reference to the node). drive-mirror did this automatically, but with blockdev-mirror this is the job of the QMP client, so it needs a way to do this. blockdev-snapshot is the obvious way, so this patch makes it work in this scenario. The new condition is that no parent uses CONSISTENT_READ permissions. This will ensure that the operation will still be blocked when the node is attached to the guest device, so blockdev-snapshot remains safe. (For the sake of completeness, x-blockdev-reopen can be used to achieve the same, however it is a big hammer, performs the graph change completely unchecked and is still experimental. So even with the option of using x-blockdev-reopen, there are reasons why blockdev-snapshot should be able to perform this operation.)

iotests: Fix _send_qemu_cmd with bash 5.1 With bash 5.1, the output of the following script changes: a=("double space") a=${a[@]:0:1} echo "$a" from "double space" to "double space", i.e. all white space is preserved as-is. This is probably what we actually want here (judging from the "...to accommodate pathnames with spaces" comment), but before 5.1, we would have to quote the ${} slice to get the same behavior. In any case, without quoting, the reference output of many iotests is different between bash 5.1 and pre-5.1, which is not very good. The output of 5.1 is what we want, so whatever we do to get pre-5.1 to the same result, it means we have to fix the reference output of basically all tests that invoke _send_qemu_cmd (except the ones that only use single spaces in the commands they invoke). Instead of quoting the ${} slice (cmd="${$@: 1:...}"), we can also just not use array slicing and replace the whole thing with a simple "cmd=$1; shift", which works because all callers quote the whole $cmd argument anyway.

block: Clarify error messages pertaining to 'node-name' 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.
