Since then we have had almost no "GPL v2 or later" notices anywhere. Since then[2][3] linux.git has replaced its version of almost the identical wording with something that's a bit more formal, and which isn't mostly addressing a hypothetical future GPL v3 migration. Let's do the same. Now we: A. Let it suffice to say that things are licensed under GPL v2 unless explicitly otherwise stated. The new wording is an amalgamation of the start of Linux's "COPYING" file[4] and the end of our pre-image first paragraph added in[1]. B. Add some brief wording about how the licenses of subdirectories such as "sha1dc/" and "compat/regex/" should be discovered. This is also intended to cover future in-tree additions such as the "reftable" directory[5][6]. C. Include the same "subject to this COPYING file" wording as linux.git has used since[7]. 1. 075b845a857 (Add a COPYING notice, making it explicit that the license is GPLv2., 2005-04-11) 2. torvalds/linux@bf02d491237e (COPYING: use the new text with points to the license files, 2018-03-23) 3. torvalds/linux@74835c7db032 (COPYING: state that all contributions really are covered by this file, 2020-02-06) 4. torvalds/linux@88de995ccf48 (COPYING: create a new file with points to the Kernel license files, 2018-03-23) 5. https://lore.kernel.org/git/2597ddfeae1d9da8695151f62379c85621ad0fcb.1632841817.git.gitgitgadget@gmail.com/ 6. https://lore.kernel.org/git/xmqqtui4k1j5.fsf@gitster.g/ 7. torvalds/linux@74835c7db032 (COPYING: state that all contributions really are covered by this file, 2020-02-06) Signed-off-by: Ævar Arnfjörð Bjarmason --- COPYING | 35 +++++++++++++++++------------------ 1 file changed, 17 insertions(+), 18 deletions(-) diff --git a/COPYING b/COPYING index 536e55524db..19de8f2ea1b 100644 --- a/COPYING +++ b/COPYING @@ -1,21 +1,20 @@ - - Note that the only valid version of the GPL as far as this project - is concerned is _this_ particular version of the license (ie v2, not - v2.2 or v3.x or whatever), unless explicitly otherwise stated. - - HOWEVER, in order to allow a migration to GPLv3 if that seems like - a good idea, I also ask that people involved with the project make - their preferences known.
