This change ensures that the update-ldcache hook is created in a manner
consistent with other nvidia-ctk hooks ensuring that a full path is
used.
Without this change the update-ldcache hook on Tegra-based sytems had an
invalid path.

If this is not done, the default config which sets the nvidia-ctk.path
option as "nvidia-ctk" will result in an invalid OCI spec if a hook is
injected. This change ensures that the path used is always an absolute
path as required by the hook spec.

This change ensures that the first match of an executable in the path
is retured instead of a list of candidates. This prevents a CDI spec,
for example, from containing multiple entries for a single executable
(e.g. nvidia-smi).

This change adds an --nvidia-ctk-path to the nvidia-ctk cdi generate
command. This ensures that the executable path for the generated
hooks can be specified consistently.
Since the NVIDIA Container Runtime already allows for the executable
path to be specified in the config the utility code to update the
LDCache and create other nvidia-ctk hooks are also updated.

The HostPath field was added in the v0.5.0 CDI specification.
The cdi package uses strict unmarshalling when loading specs
from file causing failures for unexpected fields.
Since the behaviour for HostPath == "" and HostPath == Path are
equivalent, we clear HostPath if it is equal to Path to ensure
compatibility with the widest range of specs.
This allows, for example, a v0.4.0 spec to be generated as required.

This change extends the support for multiple envvars when
specifying swarm resources to consider ALL of the specified
environment variables instead of the first match.

This change adds the discovery of DRM devices associated with requested
devices. This means that the /dev/dri/card* and /dev/dri/renderD*
devices associated with each requested NVIDIA GPU are injected into
the container and that the /dev/dri/by-path symlinks associated with
these devices are created in the container.

This change adds support for filtering entities by specifying a filter.
This can be used, for example, to check whether a mount or device
has a particular property and removing it from the set of discovered
entities if it does not.

This change adds a Devices abstraction to the CUDA image utilities. This
allows for checking whether a devices is selected, for example.

This change updates the docker config update for simplicitly.
This also allows for the API to match the crio update code.
Signed-off-by: Evan Lezar <elezar@nvidia.com>
This adds support for updating crio configs (instead of installing hooks)
and adds crio support to the nvidia-ctk runtime configure command.

This change allows the NVIDIA Container Runtime to inject vulkan
loaders and libraries by modifying the OCI runtime specification.
This allows vulkan applications to run in containers without
additional modifications.

This change adds a Locator that can be used to locate libraries.
If library names are specified, the ldcache is searched otherwise
symlinks are resolved.

This change ensures that a more concrete error is provided by the NVIDIA
Container Runtime if the NVIDIA Container Runtime hook cannot be
located.

This change adds a modifier to that injects the tegra platform files
* /etc/nv_tegra_release
* /sys/devices/soc0/family
allowing these files to be used for platform detection in a containerized
context such as the GPU device plugin.

This change adds a root member to the mounts type that is used to
perform most of the lookups for files and devices. This allows
for consistent handling of relative paths.
Signed-off-by: Evan Lezar <elezar@nvidia.com>
The Relative method added to the Locator interface was
not correctly implemented in the file type. The root was
never set when instantiating the object.
This change removes this method from the interface and the file
type, switching to a local implementation in the mounts type
instead.

Since the creation of symlinks may include other libraries / folders
the ldcache should be updated AFTER the symlinks are created.

In preparation for adding a command to the nvidia-ctk CLI to modify

This mirrors what is done in cri-o and allows for devices nodes
from, for example, the driver container to be injected into a

This change adds a charDevices discoverer and using this
for CSV, GDS, and MOFED discovery. Internally the discoverer
is a "mounts" discoverer with a charDevice locator.
Signed-off-by: Evan Lezar <elezar@nvidia.com>
Instead of creating a set of discoverers per file, this change creates
a discoverer per type by first concatenating the mount specifications
from all files. This will allow all device nodes, for example, to
be treated as a single device.

This adds a Relative function to the Locator interface and uses
this to determine the host and container paths for located files
(and devices). This ensures that the root (e.g. the nvidia driver
root) is stripped from the container path.

This change creates GDS and MOFED modifiers and adds them to the

This change adds version output to the nvidia-continer-runtime,
