2024-07-02iotests/270: Don't store data-file with json: prefix in imageKevin Wolf
We want to disable filename parsing for data files because it's too easy to abuse in malicious image files.

2024-07-02qcow2: Don't open data_file with BDRV_O_NO_IOKevin Wolf
One use case for 'qemu-img info' is verifying that untrusted images don't reference an unwanted external file, be it as a backing file or an external data file. To make sure that calling 'qemu-img info' can't already have undesired side effects with a malicious image, just don't open the data file at all with BDRV_O_NO_IO. If nothing ever tries to do I/O, we don't need to have it open. This changes the output of iotests case 061, which used 'qemu-img info' to show that opening an image with an invalid data file fails. After this patch, it succeeds. Replace this part of the test with a qemu-io call, but keep the final 'qemu-img info' to show that the invalid data file is correctly displayed in the output.

Prevent regressions when using NBD with TLS in the presence of iothreads, adding coverage the fix to qio channels made in the previous patch. The shell function pick_unused_port() was copied from nbdkit.git/tests/functions.sh.in, where it had all authors from Red Hat, agreeing to the resulting relicensing from 2-clause BSD to GPLv2.

2024-05-28block/copy-before-write: create block_copy bitmap in filter nodeVladimir Sementsov-Ogievskiy
Currently block_copy creates copy_bitmap in source node. But that is in bad relation with .independent_close=true of copy-before-write filter: source node may be detached and removed before .bdrv_close() handler called, which should call block_copy_state_free(), which in turn should remove copy_bitmap. That's all not ideal: it would be better if internal bitmap of block-copy object is not attached to any node. But that is not possible now. The simplest solution is just create copy_bitmap in filter node, where anyway two other bitmaps are created.

When running the command `qemu-img snapshot -l SNAPSHOT` the output of VM_CLOCK (measures the offset between host and VM clock) cannot to accommodate values in the order of thousands (4-digit). This line [1] hints on the problem. Additionally, the column width for the VM_CLOCK field was reduced from 15 to 13 spaces in commit b39847a5 in line [2], resulting in a shortage of space.

Furthermore, addresses a potential source of confusion by removing whitespace in column headers. Example, VM CLOCK is modified to VM_CLOCK. Additionally a '--' symbol is introduced when ICOUNT returns no output for clarity.

Since commit effd60c8 changed how QMP commands are processed, the order of the block-commit return value and job events in iotests 144 wasn't fixed and more and caused the test to fail intermittently.

2024-01-26monitor: only run coroutine commands in qemu_aio_contextStefan Hajnoczi
monitor_qmp_dispatcher_co() runs in the iohandler AioContext that is not polled during nested event loops. The coroutine currently reschedules itself in the main loop's qemu_aio_context AioContext, which is polled during nested event loops. One known problem is that QMP device-add calls drain_call_rcu(), which temporarily drops the BQL, leading to all sorts of havoc like other vCPU threads re-entering device emulation code while another vCPU thread is waiting in device emulation code with aio_poll(). Paolo Bonzini suggested running non-coroutine QMP handlers in the iohandler AioContext. This avoids trouble with nested event loops. His original idea was to move coroutine rescheduling to monitor_qmp_dispatch(), but I resorted to moving it to qmp_dispatch() because we don't know if the QMP handler needs to run in coroutine context in monitor_qmp_dispatch(). monitor_qmp_dispatch() would have been nicer since it's associated with the monitor implementation and not as general as qmp_dispatch(), which is also used by qemu-ga. A number of qemu-iotests need updated .out files because the order of QMP events vs QMP responses has changed. Solves Issue #1933.

2024-01-26iotests: port 141 to Python for reliable QMP testingStefan Hajnoczi
The common.qemu bash functions allow tests to interact with the QMP monitor of a QEMU process. I spent two days trying to update 141 when the order of the test output changed, but found it would still fail occassionally because printf() and QMP events race with synchronous QMP communication. I gave up and ported 141 to the existing Python API for QMP tests. The Python API is less affected by the order in which QEMU prints output because it does not print all QMP traffic by default. The next commit changes the order in which QMP messages are received. Make 141 reliable first.

The machine type is being detected based on "-M help" output, and we're searching for the line ending with " (default)". However, in downstream one of the machine types s marked as deprecated might become the default, in which case this logic breaks as the line would now end with " (default) (deprecated)". To fix potential issues here, let's relax that requirement and detect the mere presence of " (default)" line instead.

2023-11-21iotests: Test two stream jobs in a single iothreadKevin Wolf
This tests two parallel stream jobs that will complete around the same time and run on two different disks in the same iothreads. It is loosely based on the bug report at https://issues.redhat.com/browse/RHEL-1761. For me, this test hangs reliably with the originally reported bug in blk_remove_bs(). After fixing it, it intermittently hangs for the bugs fixed after it, missing AioContext unlocking in bdrv_graph_wrunlock() and in stream_prepare(). The deadlocks seem to happen more frequently when the test directory is on tmpfs.

2023-10-31iotests: add test for changing mirror's copy_modeFiona Ebner
One part of the test is using a throttled source to ensure that there are no obvious issues when changing the copy_mode while there are ongoing requests (source and target images are compared at the very end). The other part of the test is using a throttled target to ensure that the change to active mode actually happened. This is done by hitting the throttling limit, issuing a synchronous write and then immediately verifying the target side. QSD is used, because otherwise, a synchronous write would hang there.

2023-10-31mirror: return mirror-specific information upon queryFiona Ebner
To start out, only actively-synced is returned. For example, this is useful for jobs that started out in background mode and switched to active mode. Once actively-synced is true, it's clear that the mode switch has been completed. Note that completion of the switch might happen much earlier, e.g. if the switch happens before the job is ready, once all background operations have finished. It's assumed that whether the disks are actively-synced or not is more interesting than whether the mode switch completed. That information can still be added if required in the future. In presence of an iothread, the actively_synced member is now shared between the iothread and the main thread, so turn accesses to it atomic. Requires to adapt the output for iotest 109.

2023-10-31iotests: add tests for "qemu-img rebase" with compressionAndrey Drobyshev
The test cases considered so far: 314 (new test suite): 1. Check that compression mode isn't compatible with "-f raw" (raw format doesn't support compression). 2. Check that rebasing an image onto no backing file preserves the data and writes the copied clusters actually compressed. 3. Same as 2, but with a raw backing file (i.e. the clusters copied from the backing are originally uncompressed -- we check they end up compressed after being merged). 4. Remove a single delta from a backing chain, perform the same checks as in 2. 5. Check that even when backing and overlay are initially uncompressed, copied clusters end up compressed when rebase with compression is performed. 271: 1. Check that when target image has subclusters, rebase with compression will make an entire cluster containing the written subcluster compressed.
