I know, and, after talking with Kate about that, I actually opened a SPDX issue in Aug, 30: https://github.com/spdx/license-list-XML/issues/686 Btw, this is just the tip of the iceberg: I have another patchset pending adding the GFDL license to LICENSES and doing some changes that are required for Debian to be able to package the Kernel documentation: https://git.linuxtv.org/mchehab/experimental.git/log/?h=doc_license It starts with Ben's patch: "Documentation/media: uapi: Explicitly say there are no Invariant Sections" And tag media docs with SPDX headers. > Mauro, you wrote yourself in a reply to this patch: > > > Mental note: we'll need to push the no-invariant-sections upstream > > before merging this there. > > and then you went and applied it nevertheless without talking to anyone who > is involved with that SPDX effort of cleaning up the kernels licensing mess. Sorry, I ended by sleeping on this. This specific patch was on a separate topic branch. I completely forgot that this was waiting for SPDX committee feedback about how to use GFDL. > I'm grumpy about that particularly because you are the first person who > complains about legal implications which might affect you. > > But then you go and just ignore process and legal implications and push the > crap into mainline. > > Please get this sorted ASAP. It would be great to have an ETA from SPDX about how long they'll take to solve this issue. It has been about 2,5 months without any concrete way about how we should address it. I really don't want to add new documents at the media uAPI stuff (with is GFDL due to historical reasons) without make them also GPL. On the other hand, freezing API submissions to the media subsystem just due to the lack of proper SPDX support for GFDL seems plain wrong. Perhaps one workaround would be to explicitly not using the SPDX-License-Identifier, adding a longer licensing text that could later be replaced by a SPDX license (if they ever figure out how GFDL without invariants sections should be used). Something like: .. SPDX License for this file: GPL-2.0 OR GFDL-1.1-or-later .. .. For GPL-2.0, see LICENSES/preferred/GPL-2.0 .. .. For GFDL-1.1-or-later, see: .. .. Permission is granted to copy, distribute and/or modify this document .. under the terms of the GNU Free Documentation License, Version 1.1 or .. any later version published by the Free Software Foundation, with no .. Invariant Sections, no Front-Cover Texts and no Back-Cover Texts. .. A copy of the license is included at .. Documentation/media/uapi/fdl-appendix.rst. Will that work for you? If so, the patch solving the current issue is enclosed. I'll rebase my other SPDX patchset to use the same solution after we have an agreement on this. Thanks, Mauro media: mediactl docs: don't use SPDX for GFDL There is an open issue for using GFDL without invariant sections: https://github.com/spdx/license-list-XML/issues/686 So far, no progress. While we don't have it, we can't really use SPDX identifiers on media. So, replace them by a license text.
