Issue warning on unsupported CDI hook
Some checks failed
CI Pipeline / code-scanning (push) Has been cancelled
CI Pipeline / variables (push) Has been cancelled
CI Pipeline / golang (push) Has been cancelled
CI Pipeline / image (push) Has been cancelled
CI Pipeline / e2e-test (push) Has been cancelled
To allow for CDI hooks to be added gradually we provide a generic no-op hook
for unrecognised subcommands. This will log a warning instead of erroring out.

An unsupported hook could be the result of a CDI specification referring to a
new hook that is not yet supported by an older NVIDIA Container Toolkit
version or a hook that has been removed in newer version.

Add a hook to disable device node creation in a container
If required, this hook creates a modified params file (with ModifyDeviceFiles: 0) in a tmpfs
and mounts this over /proc/driver/nvidia/params.

This prevents device node creation when running tools such as nvidia-smi. In general the
creation of these devices is cosmetic as a container does not have the required cgroup
access for the devices.

Add enable-cuda-compat hook to allow compat libs to be discovered
This change adds an nvidia-cdi-hook enable-cuda-compat hook that checks the
container for cuda compat libs and updates /etc/ld.so.conf.d to include their
parent folder if their driver major version is sufficient.

This allows CUDA Forward Compatibility to be used when this is not available
through the libnvidia-container.

179d8655f9 Move nvidia-ctk hook command into own binary
This change creates an nvidia-cdi-hook binary for implementing
CDI hooks. This allows for these hooks to be separated from the
nvidia-ctk command which may, for example, require libnvidia-ml
to support other functionality.

The nvidia-ctk hook subcommand is maintained as an alias for the
time being to allow for existing CDI specifications referring to
this path to work as expected.
