41382879d3 seccomp: add arch_prctl syscall for amx 
When enabling amx feature, we should call arch_prctl to request
permission to use tile data for guest. The permission should be
requested before the first vcpu is created, so we need to call
arch_prctl in vmm thread. This patch adds the arch_prctl syscall for
vmm_thread_rules.

Fixes: #7516

6a86c157af misc: clippy: add needless_pass_by_value (partially) 
This helps to uncover expensive and needless clones in the code base.
For example, I prevented extensive clones in the snapshot path where
(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.

dda89d7027 tests: Check disk consistency after use 
We've encountered issues that Cloud Hypervisor corrupts disk images
after use. Those issues may not be immediately obvious until the
corrupted images are used again.

Run consistency checks over the disk images in the test cases to catch
issues as early as possible.

a1a018bd83 tests: Do not return a failure when no tests are run 
It is a common use case to run a subset of tests locally to verify
certain functionalities.

The default behaviour for nextest is to error out if no tests are run.
That causes the test scripts to return a non-zero value (failure). Pass
`--no-tests=pass` to nextest to match what `cargo test` does if no tests
are run.

28b54df01d vmm: cleanup: replace map_err misuse with inspect_err 
This is continuing the work from [0]. Some places in CHV
"misuse" Result::map_err for side-effects. inspect_err is
a better suited alternative for exactly that use-case.

Unfortunately, there is no clippy lint for this yet.

75cdfb0117 misc: arch: drop extern crate, use modern rust 
This commit is the first in a series of similar commits to clean up
obsolete `extern crate` statements

Since Rust 1.30, normal macros can be imported via `use`, and with Rust
1.31 and edition 2018 this has become the preferred approach.
`extern crate` is only needed for `alloc` in `no_std` crates, which does
not apply here.

By dropping these (often redundant or odd) `extern crate` lines, we
expose the actual dependencies more clearly and reduce technical debt.

## Auto-generation of the series

Most of this series was produced automatically:

1. Removed all "extern crate" references
2. Run the script [0] to add missing `use` statements
3. Run `cargo +nightly fmt --all`
4. Fix the remaining problems manually

The treewide changes were then split into per-folder commits.

Add tests:
- zlib: test_virtio_block_qcow2_zlib()
- zstd: test_virtio_block_qcow2_zstd()
Both these tests use zlib- and zstd-compressed images as OS image.

Modify test_virtio_block_qcow2_backing_file() test: it is practical
to test qcow2 file-backing with compression, so use zlib-compressed
image as a backing file.

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.

021f450cdb virtio-devices: proper bounds checks 
Callers of get_host_address_range() rely on it returning a pointer to at
least size bytes of memory.  mem.get_host_address() is an overrideable
method of a safe trait, so it is better for safe code to not rely on its
correctness for safety.  Instead, use mem.get_slice(), which returns a
VolatileSlice whose invariants guarantee that it points to a sufficient
amount of memory.  If mem.check_range() succeeds but mem.get_slice()
returns a slice that is too small, this means that there is either a
logic error or a situation the code cannot support yet, so panic.

8be28f8438 misc: Work around vfio_dma_map being unsound 
This API passes a u64 to a kernel API that treats the u64 as a userspace
address.  Therefore, it should be marked unsafe, but it currently is not
[1].  Wrap the call in an unsafe block to document that invariants must
be upheld to avoid undefined behavior.  This causes a compiler warning,
so suppress the warning with #[allow(unused_unsafe)].

42522a88c0 misc: do not use u64 to represent host pointers 
To ensure that struct sizes are the same on 32-bit and 64-bit, various
kernel APIs use __u64 (Rust u64) to represent userspace pointers.
Userspace is expected to cast pointers to __u64 before passing them to
the kernel, and cast kernel-provided __u64 to a pointer before using
them.  However, various safe APIs in Cloud Hypervisor took
caller-provided u64 values and passed them to syscalls that interpret
them as userspace addresses.  Therefore, passing bad u64 values would
cause memory disclosure or corruption.

Fix the bug by using usize and pointer types as appropriate.  To make
soundness of the code easier to reason about, the PCI code gains a new
MmapRegion abstraction that ensures the validity of pointers.  The rest
of the code already has an MmapRegion abstraction it can use.  To avoid
having to reason about whether something is keeping the MmapRegion
alive, reference counting is added.  MmapRegion cannot hold references
to other objects, so the reference counting cannot introduce cycles.
