Gentoo/FreeBSD On Hold Due To Licensing Issues 200

Posted by Hemos from the the-hangover-of-license-versions dept.
Alan Trick writes "Flameeyes (a Gentoo/FreeBSD developer) recently came up with some serious problems among the various *BSD projects who use BSD-4 licensed code (which is all of them). Even other projects like Open Darwin may be affected.

The saga started when he discovered the license problems with libkvm and start-stop-daemon. "libkvm is a userspace interface to FreeBSD kernel, and it's licensed under the original BSD license, BSD-4 if you want, the one with the nasty advertising clause." start-stop-daemon links to libkvm, but it's licensed under the GPL which is incompatible with the advertising clause. The good new is that the University of California/Berkley has given people permission to drop the advertising clause. The bad news is that libkvm has code from many other sources and each of them needs to give their permission for the license to be changed.

At the moment, development on the Gentoo/FreeBSD is on hold and the downloads have been removed from the Gentoo mirrors."

    But wait--wasn't the decision to link to libkvm made by the authors of the start-stop-daemon? And aren't they the same ones who decided to release it under the GPL? It would seem to me that people are looking at things the wrong way 'round. Instead of getting wavers for libkvm they should be looking at the start-stop-daemon which has either effectively been dual licensed or has been misused by whoever decided to use libkvm (idf it wasn't the original author(s)).

      Just so. The anti-4 clause movement began with the FSF. Let me stake out the position that they are not entirely objective on this point. The imfamous clause 3 problem was and has always been a canard.

      What's amazing is that people cite to the FSF propoganda and conclude they've prove their point.

      Well here is the truth of the matter: Clause 3 relates particularly to advertising that discusses the features implemented by the code given in clause 3. What this means is you want to brag about softupdates and softupdates were covered by this imfamous third clause, you would have to say 'as implemented by Kirk...'

      Anyways, this only applies to advertising with sufficient specificity to implicate particular code. Basically if you can trace a feature to 100s of contributors the clause is self-invalidating. No one contribution was responsible for the feature discussed in the advertising, therefore no mention is required.

      The whole topic has been FUD for twenty years. That said, it has been such good FUD that people have actually taken extensive effort to purge the clause from the standard license. Only a few small files retain it today.

        But the GPL specifies *no* additional restrictions, advertising clause is an additional restriction, end of story. That's all there is to it - 4 clause BSD license is not GPL compatible.

      I take it you didn't read the second link, or the summary. This covers code written by UCB, and is widely known about. All UCB-original code released under the 4-clause license can be used under the 3-clause license. However, FreeBSD does not use the original 4BSD libkvm; a number of people have submitted patches to it over the years. Because FreeBSD does not require copyright assignment, these changes are still owned by their authors, and some of them are under the 4-clause license.

      This means that parts of the library are 3-clause licensed, and parts 4-clause licensed.
