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.

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
the docker config, this change refactors load, update, and flush logic
from the toolkit container docker CLI to an internal package.

This change adds an nvidia-container-runtime.modes.cdi.spec-dirs
config option that allows the default spec dirs to be overridden.

This change reuse the code that checks for the existing NVIDIA
Container Runtime hook to ensure that both nvidia-container-toolkit
and nvidia-container-runtime-hook are detected.

This mirrors what is done in cri-o and allows for devices nodes
from, for example, the driver container to be injected into a
container at /dev instead of <ROOT>/dev

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
modifer created for the selected runtime mode if the NVIDIA_GDS
and NVIDIA_MOFED envvars are set to "enabled", respectively.

This change adds version output to the nvidia-continer-runtime,
nvidia-container-toolkit, and nvidia-ctk CLIs. The same version
is used in all cases and includes a version string and a git
revision if set.
The construction of the version string mirrors what is done in runc.

These changes replace the nvidia-container-runtime config options
experimental and discover-mode with a single mode config option.
Note that mode is now a string with a default value of "auto"
and a mode value of "legacy" is equivalent to experimental == false.

This change adds a GetContainerRoot to the oci.State type to

This change adds a CUDA image abstraction that encapsulates
