Migrate scion

[augustebaum]

https://github.com/ngi-nix/scion

part of #12

Current state:

• Uses buildGo117Module for most packages, which is not provided by our nixpkgs version.
• Has some tests, but nix flake check fails:

 '/nix/store/3vc2g0frp09zjkbfdpmj9dlkv25ddp67-source/19-ffaa_1_fe3.tar.gz': No such file or directory

and indeed the file is missing.

• nix build .#scion works.
• Provides some modules as well as the packages.

I tried to build it using buildGoModule just to check and got this error:

vendor/github.com/lucas-clemente/quic-go/internal/qtls/go118.go:5:13:
cannot use "quic-go doesn't build on Go 1.18 yet." (untyped string constant) as int value in variable declaration

which seems to suggest there are upstream dependencies that need to be updated before this flake can be ported, as per this recommendation.

Turns out @sarcasticadmin has been able to bump the Go toolchain version: ngi-nix/scion#7

It seems that nix flake check is failing in master of the ngi-nix/scion repository. And we're not sure it is trivial, so we'll see whether easier tasks are available.

Theres some remaining upstream work in scion-apps (netsec-ethz/scion-apps#246) that Im waiting on. But once that lands the drvs in ngi-nix/scion should be much more up-to-date.

[sarcasticadmin]

@mightyiam @augustebaum @lorenzleutgeb All of the upstream work has landed so the PR ngi-nix/scion#7 is ready for review

[mightyiam]

@fricklerhandwerk what NGI program is this in, please?

[fricklerhandwerk]

Closing, as SCION is already being landed in Nixpkgs NixOS/nixpkgs#298737
