2025-10-22LICENSES: Add modern form of the LGPL-2.1 tags to the usage guide sectionThomas Huth
The modern forms of the LGPL-2.1 tags have already been added as valid a long time ago, see commit bc128349588d5 ("LICENSES/LGPL-2.1: Add LGPL-2.1-or-later as valid identifiers"). However, the information is still missing in the "Usage-Guide" section, so it can currently be confusing whether these tags are allowed in new files or not. Thus add the tags to the usage guide section, too, to make this clear (similar to what we do in the GPL-2.0 file already).

2021-12-16LICENSES/LGPL-2.1: Add LGPL-2.1-or-later as valid identifiersMauro Carvalho Chehab
Some files have been flagged with the new LGPL-2.1-or-later identifier which replace the original LGPL-2.1+ in the SPDX license identifier specification, but the identifiers are not mentioned as valid in the LGPL-2.1 license file. Add it, together with the LGPL-2.1-only at the the license file.

2018-04-27LICENSES/GPL2.0: Add GPL-2.0-only/or-later as valid identifiersThomas Gleixner
Quite some files have been flagged with the new GPL-2.0-only and GPL-2.0-or-later identifiers which replace the original GPL-2.0 and GPL-2.0+ identifiers in the SPDX license identifier specification, but the identifiers are not mentioned as valid in the GPL-2.0 license file. Add them to the license file and to the Linux-syscall-note exception to make everything consistent again.

2018-01-06LICENSES: Add the GPL 2.0 licenseThomas Gleixner
Add the full text of the GPL 2.0 license to the LICENSES directory. It was copied directly from the COPYING file in the kernel source tree as it differs from the public available version of the license in various places including the FSF. Philippe did some research on the GPL2.0 history: There is NO trustworthy version of an official GPL 2.0 text: the FSF official texts are all fubar (if only in small and subtle ways). The FSF texts should be authoritative, but then which one? They published more GPL 2.0 versions than most. So we would be hard pressed to blame SPDX or the OSI for having their own minor variant. Then in digging further, I found the ONE true original GPL with a file time stamp on June 2 1991, 01:50 (AM?, PM? unknown time zone?) ! in an old GCC archive. For the posterity and everyone's enjoyment I have built a git history of GPL 2.0 Mark1 to Mark6 See https://github.com/pombredanne/gpl-history/commits/master/COPYING I also added a shorter history of the Linux COPYING text. The first version in Linus's git tree is based on the very fine and well tuned GPL 2 Mark4, the first fully Y2K compliant version of the GPL 2, as you can see from the diffs with the former Mark3: that was dangerously stuck in the last century. The current version in is based on a rare GPL 2.0 Mark5.1 aka "Franklin St", that I do not have in my history yet and spells "Franklin St." rather than "Franklin Street." Therefore there is likely another GPL 2.0 version between Mark4 and Mark5 that I have yet to find and may not have been caught by the archive.org spiders. Here help and patches welcomed: this is likely an important missing link.
