| * | qemu-iotests: adding LUKS cleanup for non-UTF8 secret errorDaniel Henrique Barboza2020-03-113-0/+79
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a new test file to exercise the case where qemu-img fails to complete for the LUKS format when a non-UTF8 secret is used.

| * | crypto.c: cleanup created file when block_crypto_co_create_opts_luks failsDaniel Henrique Barboza2020-03-111-0/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When using a non-UTF8 secret to create a volume using qemu-img, the following error happens: $ qemu-img create -f luks --object secret,id=vol_1_encrypt0,file=vol_resize_pool.vol_1.secret.qzVQrI -o key-secret=vol_1_encrypt0 /var/tmp/pool_target/vol_1 10240K Formatting '/var/tmp/pool_target/vol_1', fmt=luks size=10485760 key-secret=vol_1_encrypt0 qemu-img: /var/tmp/pool_target/vol_1: Data from secret vol_1_encrypt0 is not valid UTF-8 However, the created file '/var/tmp/pool_target/vol_1' is left behind in the file system after the failure. This behavior can be observed when creating the volume using Libvirt, via 'virsh vol-create', and then getting "volume target path already exist" errors when trying to re-create the volume. The volume file is created inside block_crypto_co_create_opts_luks(), in block/crypto.c. If the bdrv_create_file() call is successful but any succeeding step fails*, the existing 'fail' label does not take into account the created file, leaving it behind. This patch changes block_crypto_co_create_opts_luks() to delete 'filename' in case of failure. A failure in this point means that the volume is now truncated/corrupted, so even if 'filename' was an existing volume before calling qemu-img, it is now unusable. Deleting the file it is not much worse than leaving it in the filesystem in this scenario, and we don't have to deal with checking the file pre-existence in the code. * in our case, block_crypto_co_create_generic calls qcrypto_block_create, which calls qcrypto_block_luks_create, and this function fails when calling qcrypto_secret_lookup_as_utf8.

| * | block.c: adding bdrv_co_delete_fileDaniel Henrique Barboza2020-03-112-0/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Using the new 'bdrv_co_delete_file' interface, a pure co_routine function 'bdrv_co_delete_file' inside block.c can can be used in a way similar of the existing bdrv_create_file to to clean up a created file. We're creating a pure co_routine because the only caller of 'bdrv_co_delete_file' will be already in co_routine context, thus there is no need to add all the machinery to check for qemu_in_coroutine() and create a separated co_routine to do the job.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adding to Block Drivers the capability of being able to clean up its created files can be useful in certain situations. For the LUKS driver, for instance, a failure in one of its authentication steps can leave files in the host that weren't there before. This patch adds the 'bdrv_co_delete_file' interface to block drivers and add it to the 'file' driver in file-posix.c. The implementation is given by 'raw_co_delete_file'. Suggested-by: Daniel P.

| * | iotests: Add iothread cases to 155Kevin Wolf2020-03-112-11/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds test cases for attaching the backing chain to a mirror job target right before finalising the job, where the image is in a non-mainloop AioContext (i.e. the backing chain needs to be moved to the AioContext of the mirror target). This requires switching the test case from virtio-blk to virtio-scsi because virtio-blk only actually starts using the iothreads when the guest driver initialises the device (which never happens in a test case without a guest OS). virtio-scsi always keeps its block nodes in the AioContext of the the requested iothread without guest interaction.

However, it's possible that this doesn't work, but the backing file can instead be moved to the overlay's AioContext (e.g. opening the backing chain for a mirror target). bdrv_append() already indirectly uses bdrv_attach_node(), which takes care to move nodes to make sure they use the same AioContext and which tries both directions. So the problem has a simple fix: Just delete the unnecessary extra bdrv_try_set_aio_context() call in external_snapshot_prepare() and instead assert in bdrv_append() that both nodes were indeed moved to the same AioContext.

| * | iotests: Test mirror with temporarily disabled target backing fileKevin Wolf2020-03-112-7/+53
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The newly tested scenario is a common live storage migration scenario: The target node is 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. This patch adds test cases for two ways to achieve the desired result, using either x-blockdev-reopen or 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.)

This describes only some of the boards and often in a fairly abbreviated fashion. Restructure it so that each board has its own documentation file in the docs/system/arm/ subdirectory. This will hopefully encourage us to write board documentation that describes the board in detail, rather than a few brief paragraphs in a single long page. The table of contents should also help users to find the board they care about faster. Once the structure is in place we'll be able to move microvm.rst from the top-level docs/ directory. All the text from the old page is retained, except for the final paragraph ("A Linux 2.6 test image is available on the QEMU web site. More information is available in the QEMU mailing-list archive."), which is deleted. The git history shows this was originally added in reference to the integratorcp board (at that time the only Arm board that was supported), and has subsequently gradually been further and further separated from the integratorcp documentation by the insertion of other board documentation sections. It's extremely out of date and no longer accurate, since AFAICT there isn't an integratorcp kernel on the website any more; so better deleted than retained.

In this case copy_size is larger than defined for buffered IO, and there is corresponding commit. Still, backup copies data cluster by cluster, and most of requests are limited to one cluster anyway, so the only source of this one bad-limited request is copy-before-write operation. Further patch will move backup to use block_copy directly, than for cases where copy_range is not supported, first request will be oversized in each backup. It's not good, let's change it now. Fix is simple: just limit first copy_range request like buffer-based request. If it succeed, set larger copy_range limit.

Correspondingly, as progress we have total = A + B current = 0 If we reset unallocated region A and call progress_reset_callback, it will calculate 0 bytes dirty in the bitmap and call job_progress_set_remaining, which will set total = current + 0 = 0 + 0 = 0 So, B bytes are actually removed from total accounting. When job finishes we'll have total = 0 current = B , which doesn't sound good. This is because we didn't considered in-flight bytes, actually when calculating remaining, we should have set (in_flight + dirty_bytes) as remaining, not only dirty_bytes. To fix it, let's refactor progress calculation, moving it to block-copy itself instead of fixing callback. And, of course, track in_flight bytes count. We still have to keep one callback, to maintain backup job bytes_read calculation, but it will go on soon, when we turn the whole backup process into one block_copy call.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In most qemu-img sub-commands the --object option only makes sense when there is a filename. qemu-img measure is an exception because objects may be referenced from the image creation options instead of an existing image file. Allow --object without a filename.
