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

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

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

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 Fixes a bug where relative roots (e.g. as generated by contianerd)

This change adds a Requirements abstraction that can be used to check

This change adds a CUDA image abstraction that encapsulates

This change adds a DefaultExecutableDir = /usr/bin constant that is used

This change adds a cache to the mounts type. This means that if called to get
a list of folders, for example, the result is reused instead of recalculated.
This also avoids duplicate logging.

This change adds a discovered hook for updating the ldcache as a container-create
hook. The mounts from a discoverer are inspected to determine the folders that must
be added to the cache using the nvidia-ctk hook update-ldcache command.
This is added to the "csv" discovery mode for the experimental runtime.

This change adds an 'auto' discover mode that attempts to select the correct mode
for a given platform. This currently attempts to detect whether the platform is a
Tegra-based system in which case the 'csv' discover mode is used. The 'legacy'
discover mode is used as the fallback.
Signed-off-by: Evan Lezar <elezar@nvidia.com>
This change ensures that by default, the CSV discovery only considers the base CSV
files (l4t.csv, drivers.csv, devices.csv) and skips the rest unless the
NVIDIA_REQUIRE_JETPACK is set to "csv-mounts=all", in which case, all CSV files in the
specified folder are considered.

This change adds support for a "csv" discovery mode to the experimental runtime.
If this is set with experimental = true, a CSV-based discovery of devices and
mounts are used to define the modifications required to the OCI spec. The edits
are expressed as CDI ContainerEdits.

This change adds a symlink locator that follows symlinks and returns all

This change enables the experimental mode of the NVIDIA Container Runtime. If
enabled, the nvidia-container-runtime.discover-mode config option is
queried to determine how required OCI spec modifications should be defined.
If "legacy" is selected, the existing NVIDIA Container Runtime hooks is
discovered and injected into the OCI spec.

This change imports the modifying runtime abstraction from the
experimental branch. This encapsulates the checks for whether
modification is required, and forwards the loaded spec to
