This change crystallizes and simplifies the current handling of /dev
hostPath mounts with virtually no functional change.
Before this change:
- If a mount DESTINATION is in /dev and it is a non-regular file on the HOST,
the shim passes the OCI bind mount as is to the guest (e.g.
/dev/kmsg:/dev/kmsg). The container rightfully sees the GUEST device.
- If the mount DESTINATION does not exist on the host, the shim relies on
k8s/containerd to automatically create a directory (ie. non-regular file) on
the HOST. The shim then also passes the OCI bind mount as is to the guest. The
container rightfully sees the GUEST device.
- For other /dev mounts, the shim passes the device major/minor to the guest
over virtio-fs. The container rightfully sees the GUEST device.
After this change:
- If a mount SOURCE is in /dev and it is a non-regular file on the HOST,
the shim passes the OCI bind mount as is to the guest. The container
rightfully sees the GUEST device.
- The shim does not anymore rely on k8s/containerd to create missing mount
directories. Instead it explicitely handles missing mount SOURCES, and
treats them like the previous bullet point.
- The shim no longer uses virtio-fs to pass /dev device major/minor to the
guest, instead it passes the OCI bind mount as is.

genpolicy is a developer tool that should be usable on MacOS. Adding it
to the darwin CI job ensures that it can still be built after changes.
On an Apple M2, the output of `uname -m` is `arm64`, which is why a new
case is needed in the arch_to_* functions.
We're not going to cross-compile binaries on darwin, so don't install
any additional Rust targets.

This commit adds changes to enable fs sharing between host/guest
using virtio-fs when booting a pod VM for testing. This primarily
enables sharing container rootfs for testing container lifecycle
commands.
Summary of changes is as below:
- adds minimal virtiofsd code to start userspace daemon (based on
`runtime-rs/crates/resource/src/share_fs`)
- adds the virtiofs device to the test vm
- prepares and mounts the container rootfs on host
- modifies container storage & oci specs

Auto-generate policy for nginx-deployment pods, instead of hard-coding
the "allow all" policy.
Note that the `busybox_pod` - created using `kubectl run` - still
doesn't have an Init Data annotation, so it is using the default policy
built into the Kata Guest rootfs image file.

-u is also added for good measure. Note that $BATS_TEST_DIRNAME is set by

The Hadolint warning DL3007 (pin the version explicitly) is no
longer applicable.
We have updated the base image to use a specific version

We recently hit the following error during build:
```
RUN ssh-keygen -t ed25519 -f /etc/ssh/ssh_host_ed25519_key -P ""
OpenSSL version mismatch. Built against 3050003f, you have 30500010
```
This happened because `alpine:latest` moved forward and the `ssh-keygen`
binary in the base image was compiled against a newer OpenSSL version
that is not available at runtime.
Pinning the base image to the stable release (3.20) avoids the mismatch
and ensures consistent builds.

This commit addresses an issue where base64 output, when used with a
default configuration, would introduce newlines, causing decoding to
fail on the runtime.
The fix ensures base64 output is a single, continuous line using the -w0
flag. This guarantees the encoded string is a valid Base64 sequence,
preventing potential runtime errors caused by invalid characters.
Note that: When you use the base64 command without any parameters, it
typically automatically adds newlines to the output, usually every 76 chars.
In contrast, base64 -w0 explicitly tells the command not to add any
newlines (-w for wrap, and 0 for a width of zero), which results in a
continuous string with no whitespace.
This is a critical distinction because if you pass a Base64 string with
newlines to a runtime, it may be treated as an invalid string, causing
the decoding process to fail.
