Missing package license on unstable: cudaPackages.* are now unfree

[bLuka]

Summary

In order to whitelist CUDA packages license, we currently have to either whitelist CUDA packages one by one, or allow lib.licenses.unfree on the whole system.

This is a bit bothersome since there’s a lot of CUDA packages with Nvidia EULA currently with the bare lib.licenses.unfree license attached (even though they get proper license match on search.nixos.org.

I can’t figure out if the change was intended between 23.11 and unstable. For instance, for cudaPackages.cuda_cccl:

• On 23.11, it has lib.licenses.nvidiaCudaRedist
• On unstable, it has lib.licenses.unfree

Proposed change

I didn’t want to push a PR as I don’t know if it would have side effects to unexpected packages, but I believe we could replace licenses.unfree by licenses.nvidiaCudaRedist on pkgs/development/cuda-modules/generic-builders/manifest.nix:344.

Would that make sense?

the license seems to be correctly using nvidiaCudaRedist for cudaPackages.cuda_cccl on nixos-unstable:

$ nix eval --impure --expr '(builtins.getFlake "github:nixos/nixpkgs/nixos-unstable").legacyPackages.x86_64-linux.cudaPackages.cuda_cccl.meta.license'

{ deprecated = false; free = false; fullName = "CUDA Toolkit End User License Agreement (EULA)"; redistributable = true; shortName = "CUDA EULA"; url = "https://developer.download.nvidia.com/compute/cuda/redist/cuda_cccl/LICENSE.txt"; }

Oops! I think I got a bit lost by the sources, thank you for pointing it out!

I got a bit confused also because I was unable to accept the license using allowlistedLicenses = with lib.licenses; [ nvidiaCudaRedist ];

It looks like the reason is because the link contained within the package’s license is different from the original license link:

$ nix eval --impure --expr '(builtins.getFlake "github:nixos/nixpkgs/nixos-unstable").legacyPackages.x86_64-linux.cudaPackages.cuda_cccl.meta.license'
{ deprecated = false; free = false; fullName = "CUDA Toolkit End User License Agreement (EULA)"; redistributable = true; shortName = "CUDA EULA"; url = "https://developer.download.nvidia.com/compute/cuda/redist/cuda_cccl/LICENSE.txt"; }

$ nix eval --impure --expr '(builtins.getFlake "github:nixos/nixpkgs/nixos-unstable").lib.licenses.nvidiaCudaRedist.url'
{ deprecated = false; free = false; fullName = "CUDA Toolkit End User License Agreement (EULA)"; redistributable = true; shortName = "CUDA EULA"; url = "https://docs.nvidia.com/cuda/eula/index.html#cuda-toolkit-supplement-license-agreement"; }

Is the package’s license definition allowing me to properly whitelist lib.licenses.nvidiaCudaRedist for all packages?
