We are using a similar sign-off process that is used for contributions to the Linux kernel. This means developers making contributions certify that they wrote the patch or have the right to pass it on. To certify this, you include a Signed-off-by: line like this one at the bottom of your commit comments that contains your real name (not an alias):
Signed-off-by: Random J Developer <email@example.com>
With the git commit -s/--signoff option, Git automatically appends a Signed-off-by: line to the log message with the currently-configured Git account and email (from the ~/.gitconfig or .git/config entries for name= and email=).
Adding this line means that you certify the following:
Developer's Certificate of Origin 1.1 By making a contribution to this project, I certify that: (a) The contribution was created in whole or in part by me and I have the right to submit it under the open source license indicated in the file; or (b) The contribution is based upon previous work that, to the best of my knowledge, is covered under an appropriate open source license and I have the right under that license to submit that work with modifications, whether created in whole or in part by me, under the same open source license (unless I am permitted to submit under a different license), as indicated in the file; or (c) The contribution was provided directly to me by some other person who certified (a), (b) or (c) and I have not modified it. (d) I understand and agree that this project and the contribution are public and that a record of the contribution (including all personal information I submit with it, including my sign-off) is maintained indefinitely and may be redistributed consistent with this project or the open source license(s) involved.
Changes submitted to the release branch without the Signed-off-by: line will be rejected.
