Add a validator which checks that a bitmap spanning multiple backing chain members doesn't look broken. The current rules are that no intermediate birmaps are missing (unfortunately it's hard to know whether the topmost or bottommost bitmap is missing) and none of the components is inconsistent. We can obviously improve it over time. The validator is also tested against the existing bitmap data we have for the backup merging test as well as some of the existing broken bitmap synthetic test cases.

libvirt treats 'luks' images as raw+encryption. The logic in qemuBlockStorageSourceCreateFormat skipped the creation if the requested image was raw but didn't take into account the encryption. This manifested itself e.g. when attempting to do a virsh blockcopy with the following XML: <disk type='file' device='disk'> <driver name='qemu' type='raw'/> <source file='/tmp/enccpy'> <encryption format='luks'> <secret type='passphrase' uuid='0a81f5b2-8403-7b23-c8d6-21ccc2f80d6f'/> </encryption> </source> </disk> Where qemu would report the following error: unable to execute QEMU command 'blockdev-add': Volume is not in LUKS format rather than actually formatting the image first.

This previous commit introduced a simpler free callback for hash data with only 1 arg, the value to free: commit 49288fac Author: Peter Krempa <pkrempa@redhat.com> Date: Wed Oct 9 15:26:37 2019 +0200 util: hash: Add possibility to use simpler data free function in virHash It missed two functions in the hash table code which need to call the alternate data free function, virHashRemoveEntry and virHashRemoveSet. After the previous patch though, there is no code that makes functional use of the 2nd key arg in the data free function. There is merely one log message that can be dropped. We can thus purge the current virHashDataFree callback entirely, and rename virHashDataFreeSimple to replace it. Reviewed-by: NMichal Privoznik <mprivozn@redhat.com> Signed-off-by: NDaniel P.

In case when the backing store can be represented with something simpler such as a URI we can use it rather than falling back to the json: pseudo-protocol. In cases when it's not worth it (e.g. with the old ugly NBD or RBD strings) let's switch to json. The function is exported as we'll need it when overwriting the ugly strings qemu would come up with during blockjobs.

To allow using -blockdev with blockjobs QEMU needs to reopen files in read-write mode when modifying the backing chain. To achieve this we need to use 'auto-read-only' for the backing files rather than the normal 'read-only' property. That way qemu knows that the files need to be reopened. Note that the format drivers (e.g. qcow2) are still opened with the read-only property enabled when being a member of the backing chain since they are supposed to be immutable unless a block job is started. QEMU v4.0 (since commit 23dece19da4) allows also dynamic behaviour for auto-read-only which allows us to use sVirt as we only grant write permissions to files when doing a blockjob.
