All contributions to this project should include acceptance of the Developer Certificate of Origin (DCO).
From Wikipedia:
"The Developer Certificate of Origin (DCO) was introduced in 2004 by the Linux Foundation, to enhance the submission process for software used in the Linux kernel, shortly after the SCO–Linux disputes. ... a DCO is an affirmation that the source code being submitted originated from the developer, or that the developer has permission to submit the code."
