antlr3 and a not-allowed license
by Jerry James 31 Jan '26

31 Jan '26

I've been using scancode to take an in-depth look at packages I maintain. I'm up to packages that start with "a"! While looking at the antlr3 package, I found that it contains 3 files with the LicenseRef-Unicode-legacy-source-code license, which is not allowed for Fedora [1]. The files are part of the C/C++ backend. They have been built into binary RPMs for Fedora since 2010 [2] (Fedora 12?). Repoquery shows that nothing in Fedora uses the C/C++ backend. I will build updates for F42, F43, and Rawhide that disable it. My question is whether I need to do anything more than that. Do I need to scrub the offending files out of the tarball, for example?

If non-code stuff is CC0, then the license is still valid and must be identified. I do recommend that you package the dependencies individually though, otherwise it's going to be messy when it comes to auditing, fixing, and upgrading dependencies. -- 真実はいつも一つ！/ Always, there's only one truth!

Question about two Fedora packages that are CC0
by Máirín Duffy 15 Jan '26

15 Jan '26

Hi Fedora Legal! 👋 I have a question about two packages in Fedora that are dependencies for goose, which our (Rodolfo and I's) team are working on packaging for Fedora. They are: - *constant_time_eq* - https://packages.fedoraproject.org/pkgs/rust-constant_time_eq/ - *tiny-keccak - * https://packages.fedoraproject.org/pkgs/rust-tiny-keccak *constant_time_eq*'s upstream states it may be used under CC0, Apache 2.0, or MIT at the user's option: https://github.com/cesarb/constant_time_eq (see README) *tiny-keccak *is CC0 only, though: https://github.com/debris/tiny-keccak Goose is built in Rust, and we're looking at packaging it as a bundle and vendoring dependencies like these. They already exist in Fedora, but not sure what the policy is on pre-existing libraries like these. Questions: - Assuming just because these are already packaged in Fedora, doesn't mean they're ok to vendor in another Fedora package. Correct? - Can we use one of the other licenses for *constant_time_eq* which are acceptable for Fedora packages? Or are there any concerns there? - Do you have any advice on how to handle *tiny-keccak*'s license? Greatly appreciate your help in advance!! Thanks, ~m
