Dear Ilya, dear Mikhail, thank you for pointing out clear original authorship and license information in the files you have contributed. Due to these pointers, ./scripts/spdxcheck.py has identified these files licensed under the Zlib License and reports: lib/zlib_dfltcc/dfltcc.c: 1:28 Invalid License ID: Zlib lib/zlib_dfltcc/dfltcc.h: 1:28 Invalid License ID: Zlib lib/zlib_dfltcc/dfltcc_deflate.c: 1:28 Invalid License ID: Zlib lib/zlib_dfltcc/dfltcc_inflate.c: 1:28 Invalid License ID: Zlib lib/zlib_dfltcc/dfltcc_util.h: 1:28 Invalid License ID: Zlib As there is currently no Zlib license text in LICENSES, I believe you must simply add the Zlib license text to LICENSES/deprecated. The documentation states deprecated licenses should only be used for existing code or for importing code from a different project, which is the case here. Just in case you are not aware, more documentation on licensing is here: https://www.kernel.org/doc/html/latest/process/license-rules.html Best regards, Lukas
