7c99c169ba block: qcow: Validate incompatible feature bits 
Parse the feature name table header extension to provide descriptive
error messages when unsupported incompatible features are detected.
Currently only the compression bit (bit 3, zstd) is supported.

This prevents opening qcow2 images with features that would cause
incorrect behavior or data corruption (e.g., dirty bit, corrupt bit,
external data file, extended L2 entries).

Feature names are defined as follows:
1. The image's feature name table header extension (if present)
2. Hardcoded fallback names for known features
3. Generic "unknown feature bit N" for undefined features

13198777dd block: qcow: Add support for zero bit in standard L2 clusters 
Implement read support for bit 0 in QCOW2 L2 table entries.
When this flag is set, the cluster reads as zeros without accessing
disk. This improves compatibility with QCOW2 images that use this
optimization.

According to the QCOW2 specification, bit 0 of the standard cluster
descriptor indicates that the cluster reads as zeros. Unlike
l2_entry == 0 indicating a completely unallocated entry, bit 0 can
be set on an allocated cluster.

3fed706d6a block: qcow: Fix v3 header writing and add extension tests 
The write_to() function is used by test code to create qcow2 files for
testing. For v3 headers with extended header_size (>104), it needs to:

1. Write the mandatory compression_type field at bytes 104-111
2. Write the header extension end marker at the header_size offset
3. Seek to backing_file_offset before writing the backing file path

Additionally, create_for_size_and_path() must set backing_file_offset
to account for the 8 byte extension end marker in v3 files, so the
backing file path doesn't overwrite the extension area.

Add unit tests for read_header_extensions() covering backing format
parsing (raw/qcow2), unknown extensions, and error cases (invalid
formats, invalid UTF-8). These tests depend on the header writing fixes
to create properly formatted v3 test files.

9eb2b9b0e5 block: qcow: Implement extension parsing for QCOW v3 
Add support for parsing QCOW v3 header extensions to read the
backing file format. The QCOW v3 spec allows optional header
extensions between the fixed header and the backing file name.

Implement read_header_extensions() to parse the extension area,
which starts at the header_size offset. At the moment it is
used to read the backing file format. Further extension
processing is open in folow up implementations.

b3922dbd2c block: qcow: Add raw backing file support 
Add support for raw backing files in addition to qcow2 backing
files. This enables QCOW2 overlays to use raw images as their
backing store.

The backing file format is auto-detected when not specified,
using the existing detect_image_type() function.

Add backing_file_format field to QcowHeader to store the format
type, which will be populated from header extensions by a
subsequent patch.

Modify new_from_backing() to accept a backing_format parameter,
consolidating support for both raw and qcow2 backing files in a
single function. The backing_file_size parameter allows overlay
creation without opening the backing file multiple times.

5c5f33050c block: qcow: Refactor pointer table writes to use iterators 
Refactor write_pointer_table to accept iterators instead of requiring
materialized vectors, eliminating temporary allocations in L1 table
sync operations.

Changes:
- Modified write_pointer_table() to take Iterator<Item = &T> and
  dereference internally before passing owned values to the callback
- Added write_pointer_table_direct() convenience wrapper for cases
  without value transformation
- Updated sync_caches() to use l1_table.iter() directly instead of
  .get_values().iter().copied()
- Implemented Deref<Target = [T]> for VecCache to enable direct .iter()

Performance impact:
- Eliminates L1 table allocation during sync (~2KB per 100GB disk)
- L2 and refcount table writes already used slices, no change there
- Zero performance overhead: iterator dereferencing is equivalent to
  .copied() and optimizes identically

The L1 sync previously collected entries into a Vec to apply the
OFLAG_COPIED flag. The new iterator+callback pattern computes this
on-the-fly, avoiding the allocation entirely.

efad6578d1 block: qcow: Fix refcount leak when converting compressed clusters 
When converting a compressed cluster to standard during write
operations, the old compressed cluster's refcount was never
decremented, causing leak warnings by `qemu-img check ..`

`Leaked cluster X refcount=N reference=M`

Additionally, compressed data can span multiple physical clusters,
not just one. The compressed cluster address and size are encoded
in the L2 entry, and the data may cross cluster boundaries.

The proper handling is implemented as follows:
- Extract compressed cluster address and size before overwriting
  L2 entry
- Identify all clusters occupied by the compressed data
- Decrement refcount for each cluster in the range

9e2e85a48f block: qcow: Fix refcount leak when refcount blocks are replaced 
When a refcount block is evicted from cache and replaced with a new
one, the old refcount block cluster was added to unref_clusters but
its refcount was never decremented to 0 on disk. This left the cluster
with refcount=1 while no metadata referenced it, causing errors in
qemu-img check

`Leaked cluster X refcount=1 reference=0`

This fix recursively calls set_cluster_refcount(freed_cluster, 0) to
properly decrement the freed refcount block's refcount on disk. The
recursion handles cascading replacements where freeing one refcount
block may trigger the replacement of another.

6897c2a462 block: qcow: Set OFLAG_COPIED bit in L1 entries for spec compliance 
The OFLAG_COPIED bit (bit 63) indicates a cluster's refcount is exactly
1 and doesn't need copy-on-write. This bit must be set in L1 entries
when their referenced L2 clusters have refcount=1.

Previously, L1 entries were always written as raw addresses without the
OFLAG_COPIED bit, violating the QCOW2 specification and causing qemu-img
check to report errors like

`ERROR OFLAG_COPIED L2 cluster: l1_index=X .... refcount=1`

The implementation queries each L2 cluster's refcount in sync_caches()
and sets OFLAG_COPIED appropriately when writing the L1 table. This
ensures QCOW2 images are specification compliant and maintain correct
COW semantics to avoid data corruption.

Previously the code relies on the implicit flush when BufWriter is

Per BufWriter's document:

```
It is critical to call flush before BufWriter<W> is dropped. Though
dropping will attempt to flush the contents of the buffer, any errors
that happen in the process of dropping will be ignored. Calling flush
ensures that the buffer is empty and thus dropping will not even attempt

(nested) BTreeMap's have been cloned over and over again. Further,
the lint helps devs to much better reason about the ownership of
parameters.

All of these changes have been done manually with the necessary
caution. A few structs that are cheap to clone are now `copy` so that
this lint won't trigger for them.

I didn't enable the lint so far as it is a massive rabbit hole and
needs much more fixes. Nevertheless, it is very useful.

aa67250049 block: qcow: support compressed clusters (zlib, zstd) 
Add support of reading and writing compressed clusters.
Support zlib and zstd compressions.

L2 cache: store entire L2 entries, not only standard cluster addresses.

Read path. Offsets of compressed clusters cannot be determined,
therefore replace QcowFile.file_offset_read() with QcowFile.file_read().
This method reads the cluster, decompresses it if necessary and returns
the data to the caller.

Write path. QcowFile.file_offset_write(): since writing to compressed
clusters is not generally possible, allocate a new standard
(non-compressed) cluster if compressed L2 entry is encountered; then
decompress compressed cluster into new cluster; then return offset
inside new cluster to the caller. Processing of standard clusters is
not changed.

f5d2973546 block: advisory locks: use byte-range locks to match QEMU behavior 
The granularity has significant implications in typical cloud
deployments with network storage. The Linux kernel will sync advisory
locks to network file systems, but these backends may have different
policies and handle locks differently. For example, Netapp speaks a NFS
API but will treat advisory OFD locks for the whole file as mandatory
locks, whereas byte-range locks for the whole file will remain
advisory [0].

As it is a valid use case to prevent multiple CHV instances from
accessing the same disk but disk management software (e.g., Cinder in
OpenStack) should be able to snapshot disks while VMs are running, we
need special control over the lock granularity. Therefore, it is a valid
use case to lock the whole byte range of a disk image without
technically locking the whole file - to get the best of both worlds.

This also brings CHVs behavior in line with QEMU [1].

Whole-file locks remain a valid use case and could be supported later.
This patch only provides the necessary groundwork; making it
configurable is out of scope for now.

3791062b23 block: qcow: refactor: extract method cache_l2_cluster() 
There are several copy-pasted code fragments in impl QcowFile. All of
them add L2 entry to the cache and one of them (in file_offset_write())
does also allocating new L2 entry if necessary.

Fold all these code fragments (except of one in l2_table() which does
error handling in special way) into cache_l2_cluster() method without
changing the logic.
This will make the code more compact and clean.

7536a95424 misc: cleanup &Arc<dyn T> -> &dyn T 
Consuming `&Arc<T>` as argument is almost always an antipattern as it
hides whether the callee is going to take over (shared) ownership
(by .clone()) or not. Instead, it is better to consume `&dyn T` or
`Arc<dyn T>` to be more explicit. This commit cleans up the code.

The change is very mechanic and was very easy to implement across the
code base.

061351d82d build: upgrade whole* workspace to Rust edition 2024 
This upgrades the Cargo workspace to Rust edition 2024 to keep the
code base clean and up to date.

The commit only contains the adjustments to the Cargo.toml files and
basic compiler error fixes. Also, this commit includes new SAFETY
comments as discussed in [1]. The changes were not automatically
fixed by `cargo fix --edition` but needed manual adjustments.

Apart from that, all formatting and clippy adjustments follow in
subsequent commits.

*
As only exception, workspace member net_gen sticks to edition 2021
for now as discussed in [0].

Cache and batch IO requests after parsing all

for small block sizes—by reducing per-request overhead.

Introduced two methods in the AsyncIo trait for batch
submission, with implementation in the raw disk backend.
This method should be called during/after parsing all block IO requests
in the available queue. If the batch submission is not enabled, by
default it does the old way of submitting requests.
