Build regular block volumes with BlockConfigModern and submit them
through DeviceConfig::BlockCfgModern. Preserve the existing block
device attributes while also recording the host path required by the
modern block device model.
Update block volume helper call sites with the default option slice
so this change remains buildable with the modern helper signature.

Switch the Cloud Hypervisor device handling path from the legacy
Block device variant to BlockModern. Keep the block device behind
its shared mutex while snapshotting the configuration for the
hotplug request, and persist the PCI path assigned by Cloud
Hypervisor back into the shared device state.

Introduce build_bind_mount_options() to construct OCI mount options for
container-side bind mount, preferring volume_options over OCI options
and ensuring a bind/rbind flag is present.
And addfilter_block_storage_options() to strip bind/rbind flags from
Storage.options, preventing ENOTDIR when the agent mounts a block
device to a filesystem inside the guest.
And then Extend handle_block_volume() with a volume_options parameter
and replace hardcoded ro/empty options with the new filter+ro logic,
narrowing the function to a BlockModern-only path by removing the
DeviceType::Block branch.
Fix generate_shared_path to always create under rw/ since ro/
is a read-only bind mount of rw/ and direct creation fails with ReadOnly
FS. Switch the OCI Mount type from fs_type to KATA_MOUNT_BIND_TYPE because
the mount source is a directory (guest_path), not a block device.

Move the block device type definitions shared between BlockDevice and
BlockDeviceModern — VIRTIO_BLOCK_{PCI,MMIO,CCW}/VIRTIO_PMEM constants,
KATA_*_DEV_TYPE aliases, and the BlockDeviceAio / BlockDeviceFormat
enums — from virtio_blk.rs into virtio_blk_modern.rs, so they live
alongside the BlockModern handler that will replace the legacy
BlockDevice.
Add a `format: BlockDeviceFormat` field to BlockConfigModern to match
the legacy BlockConfig. Update mod.rs re-exports accordingly.
No behavior change; pure relocation plus the new field.

Extend the kata-deploy host-check stage with EROFS-specific
prerequisite validation.
Check that containerd supports the EROFS snapshotter, required
kernel features are available either as loaded modules or built-in
kernel configuration, and the host erofs-utils version satisfies the
minimum required by kata-deploy's configured mkfs options. Also warn
when kubelet runtimeRequestTimeout appears too low for EROFS layer
conversion, which can run during CreateContainer.
Read kubelet runtimeRequestTimeout from kubelet /configz through the
apiserver node proxy, and add the corresponding RBAC permission. Keep
fs-verity validation warning-only because user drop-ins may override
kata-deploy's default enable_fsverity setting and kata-deploy does
not yet validate the backing filesystem's fs-verity feature.

src/dragonball/out is an 893 KB `cargo metadata` JSON dump that was swept
into the tree by accident in commit 1d2d2cc3d ("ci: Remove duplicated
rust-vmm dependencies"), whose only intended change was a one-line edit to
.github/dependabot.yml. Nothing references the file -- no script, CI job,
or Makefile -- so it is pure build cruft. Remove it.

At src/dragonball/, the dragonball crate's own module tree (src/) sat as a
sibling of whole separate crates (dbs_acpi/, dbs_pci/, ...). That level
mixed one crate's guts with other crates -- neither cleanly one crate nor
a clean set of crates. Move the dbs_* under src/dragonball/crates/ so the
top level is the dragonball crate plus a crates/ folder of its libraries,
matching the layout src/runtime-rs already uses.
The dbs_* were imported ~2 years ago from the standalone dragonball-sandbox
repo and kept that repo's flat layout verbatim. They are now private to
kata (unpublished, versions frozen) -- plain internal workspace members --
so no external consumers are affected and the "independently published
building blocks" rationale for the flat layout no longer holds. Pure
layout change; no code or build behavior changes.

In confidential mode, the host is not trusted and might try to create
malicious files in the guest VM. This commit changes the implementation
of the CopyFile method to use pathrs, which is designed to prevent
accidental writes to locations outside the shared directory
(/run/kata-containers/shared/containers). It also adds a detailed
description of what the method does, and test cases for intended and
malicious use cases.
This was originally considered as a mitigation candidate for
https://github.com/kata-containers/kata-containers/security/advisories/GHSA-q49m-57vm-c8cc,
but we decided to go with the simpler change to address the immediate
risk. It's still desirable to lock down CopyFile writes for defense in
depth, thus the resubmission outside the GHSA.

dmverity_mode=auto can preserve existing EROFS layers without
dm-verity metadata, which lets mixed-mode nodes keep running with
partially unprotected image layers.
Use dmverity_mode=on when kata-deploy enables EROFS dm-verity so
missing metadata is reported instead of silently accepted.
Also tighten the Kubernetes probe. Instead of checking for at least one
dm-verity line and one EROFS dm mount in dmesg, derive the expected
workload layer count from the root overlay lowerdirs and require matching
kata-verity devices and dm-backed EROFS mounts.
