Update dbs-virtio-devices to compile with:
- virtio-bindings 0.2.x: VIRTIO_F_VERSION_1, VIRTIO_F_NOTIFY_ON_EMPTY,
VIRTIO_F_RING_PACKED moved from virtio_blk/virtio_net/virtio_ring to
virtio_config module.
- virtio-queue 0.17.0: Descriptor no longer exported at top level, use
desc::split::Descriptor instead.
- vhost 0.15.0: Master->Frontend, VhostUserMaster->VhostUserFrontend,
MasterReqHandler->FrontendReqHandler,
VhostUserMasterReqHandler->VhostUserFrontendReqHandler,
SLAVE_REQ->BACKEND_REQ, SLAVE_SEND_FD->BACKEND_SEND_FD,
set_slave_request_fd->set_backend_request_fd.
FS slave messages (VhostUserFSSlaveMsg etc.) removed from vhost crate;
SlaveReqHandler now implements VhostUserFrontendReqHandler with
handle_config_change only.
- fuse-backend-rs 0.14.0: Handle CachePolicy::Metadata variant,
fix get_rootfs() returning tuple, use buffer-based I/O for Ufile
since ReadVolatile/WriteVolatile are not implemented for Box<dynUfile>.
- vm-memory 0.17.1: GuestRegionMmap::new returns Option instead of
Result, mmap::Error removed.

Moving the genpolicy crate into the root workspace causes the build
outputs to go into the root workspace's target directory, instead of
src/tools/genpolicy/target, invalidating assumptions made by the
kata-deploy-binaries script.
This commit adds a special case for the lookup path of the genpolicy
binary, and fixes two bugs that made identifying this problem harder.

This commit adds the genpolicy utility to the root workspace. For now,
only dependencies that are already in the root workspace are consumed
from there, the genpolicy-specific ones should be added later.

Before this change, `make test` for runtime-rs used to test all crates
in the root workspace (due to the `--all` flag). This was not intended
but happened to be mostly working. However, genpolicy needs additional
steps before it can build, so this behavior blocks adding genpolicy to
the root workspace.
The solution here is to only build the inteded packages. For the build
and run commands, this is the runtime-rs crate itself. For testing, we
need to include the sub-crates, too, which needs a bit of cargo metadata
scraping.

1. Reduce the complexity of the new allow_mount rules for emptyDir.
2. Reverse the order of the two allow_mount versions, as a hint to the
rego engine that the first version is more often matching the input.
3. Remove `p_mount.source != ""` from mount_source_allows, because:
- Policy rules typically test the values from input, not values read
from Policy.
- mount_source_allows is no longer called for emptyDir mounts after
these changes, so p_mount.source is not empty.

It can be useful to set these variables during local testing:
* AZ_REGION: Region for the cluster.
* AZ_NODEPOOL_TAGS: Node pool tags for the cluster.
* GENPOLICY_BINARY: Path to the genpolicy binary.
* GENPOLICY_SETTINGS_DIR: Directory holding the genpolicy settings.
I've also made it so that tests_common.sh modifies the duplicated
genpolicy-settings.json (used for testing) instead of the original git-tracked
one.

* Introduces a new cluster_config setting encrypted_emptydir defaulting to true.
* Adapts genpolicy for encrypted emptyDirs.
Crucially, the rules.rego change checks that the mount and the storage are
well-formed together:
* i_storage.source matches a known regex.
* i_storage.mount_point == $(spath)/BASE64(i_storage.source)
* i_storage.mount_point == p_storage.mount_point
* i_storage.mount_point == i_mount.source
Note that policy enforcement is necessary to prevent rogue device injection.
E.g. the agent could not blindly encrypt all block devices as some use cases
only need dm-verity.

* Introduces the `emptydir_mode` config flag to allow instructing the runtime
to create a block device for emptyDir volumes.
* The block device is created in the original emptyDir folder on the host
so that Kubelet can monitors its disk usage and evict the pod if it exceeds
its sizeLimit. This matches runc and virtio-fs.
* The block device's disk image file is sparse to minimize host disk
footprint.

The vhost-kern net unit test used a fixed TAP interface name
("test_vhosttap"). When tests run in parallel or a previous run
leaves the interface behind, TAP creation can fail with
EBUSY ("Resource busy"), making CI flaky.
Introduce a unique_tap_name() helper in the tests and use it to
generate a per-test TAP name (based on pid/thread/counter),
avoiding name collisions and stabilizing CI.

The signal_handler test was intermittently failing because it used
kill(pid, sig), which sends signals asynchronously to the process.
This created a race condition where the child thread could exit and
be joined before the signal was delivered or processed.
This fix including:
1. Replaces `kill` with `libc::raise` to ensure signals are delivered
synchronously to the calling thread.
2. Reorders triggers to verify standard signals before installing
seccomp filters.
3. Guarantees that metrics are incremented before the child thread
terminates and is joined by the main thread.

The vhost-user-net tests could hang in CI because
VhostUserNet::new_server() blocks indefinitely on listener.accept()
when the slave fails to connect in time
(e.g. due to scheduler delays or flaky socket paths). This also caused
panics when connect_slave() returned None and the test unwrapped it.
Fix the tests by:
- using a `/tmp`, absolute, unique unix socket path per test run
retrying slave connect with a deadline
- running new_server() in a separate thread and waiting via
recv_timeout() to ensure the test never blocks indefinitely

It aims to fix flaky test hang by implementing thread timeouts.
The `test_vhost_user_net_virtio_device_normal` was hanging in CI
when master/slave threads drifted.
This commit stabilizes the test by:
- Using `tempfile` and unique paths to ensure socket isolation.
- Adding a 5s deadline for slave connections to handle CI jitter.
- Running `new_server` in a separate thread with a `recv_timeout`
to prevent the CI pipeline from deadlocking.

The `test_inner_stream_timeout` test case was prone to failure due to a
race condition between the main thread and the background handler. The
test relied on hardcoded `thread::sleep` durations, which could cause
the second read operation to time out (150ms window) before the main
thread performed its write (after a 300ms sleep) under high system load.
This commit stabilizes the test by:
1. Replacing fixed sleep durations with a `Condvar` and a `stage`
variable to implement a deterministic state machine.
2. Synchronizing the threads so that the main thread only writes data
after the background handler has confirmed it is ready or has
completed its previous phase.
3. Ensuring the read timeout is explicitly managed between different
validation stages to prevent accidental `TimedOut` errors.
This change eliminates the flakiness and ensures the test passes
consistently across different CIenvironments.

This commit aims to address issues of "Infinite loop in epoll_manager
tests" and improve stablity.
Root causes as below:
1. Using `handle_events(-1)` caused the worker thread to block forever
if an event was missed or if the internal `kick()` signal was not
accounted for correctly.
2. Relying on event counts was unreliable because internal signals could
fluctuate the total count, causing the it to enter an infinite loop.
3. Using `EventSet::OUT` on an EventFd is often continuously ready,
leading to non-deterministic trigger behavior.

In some CI runs, `mktemp` generates random characters that accidentally
form file extensions like `.cSV` or `.Xml`. This triggers downstream
parsing errors because the YAML content is misidentified as CSV/XML.
The issues look like as below:
```
'/tmp/bats-run-KodZEA/.../pod-guest-pull-in-trusted-storage.yaml.in.cSV':
...
```
This commit fixes the issue by:
1. Moving the `XXXXXX` placeholder before the `.yaml` extension.
2. Ensuring the generated file always ends in `.yaml`.
This prevents format misidentification while maintaining filename
uniqueness and security.
