If a ConfigMap has more than 8 files it will not be mounted watchable
[1]. However, genpolicy assumes that ConfigMaps are always mounted at a
watchable path, so containers with large ConfigMap mounts fail
verification.
This commit allows mounting ConfigMaps from watchable and non-watchable
directories. ConfigMap mounts can't be meaningfully verified anyway, so
the exact location of the data does not matter, except that we stay in
the sandbox data dirs.

Our current set of authenticated registry tests involve setting
kernel_params to config the image pull process, but as of
kata-containers#11197
this approach is not the main way to set this configuration and the agent
config has been removed. Instead we should set the configuration in the
`cdh.toml` part of the initdata, so add new test cases for this. In future, when
we have been through the deprecation process, we should remove the old tests

- copy default-initdata.toml in create_tmp_policy_settings_dir, so it can be modified by other tests if needed
- make auto_generate_policy use default-initdata.toml by default
- add auto_generate_policy_no_added_flags, so it may be used by tests that don't want to use default-initdata.toml by default

There's no reason to have the code duplication between the SNP / TDX
tests for CoCo, as those are basically using the same configuration
nowadays.
Note that for the TEEs case, as the nydus-snapshotter is deployed by the
admin, once, instead of deploying it on every run ... I'm actually
removing the nydus-snapshotter steps so we make it clear that those
steps are not performed by the CI.

We already have support for deploying a few flavours of k8s that are

Let's also add the ability to deploy vanilla k8s, as that will be very

Introduce new test case which verifies that openvpn clients and servers
can run as Kata pods and can successfully establish a connection.
Volatile certificates and keys are generated by an initialization
container and injected into the client and server containers.
This scenario requires TUN/TAP support for the UVM kernel.

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.

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

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.
