Worked on the openwrt/packages repository to implement a ZeroTier license compliance update, focusing on aligning the package with the MPL-2.0 license and ensuring exclusion of non-free code when the ZT_NONFREE build flag is set. This involved updating licensing metadata, refining package management processes, and maintaining build stability across architectures. The approach emphasized open source compliance by enhancing traceability through structured commit messages and referencing upstream release notes. Utilizing Makefile and build-flag handling, the work reduced licensing risk and prepared the package for future upstream changes, while preserving existing features and ensuring that documentation accurately reflected the new compliance posture.
