Verification of License and Copyrights is automated on Github by Licensing test.
The rules for Licenses and Copyrights are as follows:
- Preferred comment mark should be used for file type. Please prefer to test or other files for
examples. For
.cand.hfiles, it is//. - SPDX Licenses must be used:
- It must be on the first or the third line (only if interpreter is defined);
- Verification script contains set of allowed licenses for directories to avoid legal issues. If you need to honor other license types, tests must be extended.
- Immediately after SPDX header Copyright lines may come. There are multiple Copyrights lines allowed.
- Only Intel copyright must follow strict style check.
- The block must be ended by empty line.
Commits must pass kernel Checkpatch. There are some excludes and it is automatically tested on Github.
