Revision as of 21:42, 1 August 2008
In May 2004, the kernel development community decided to standardize on a requirement to adhere to a Developer Certificate of Origin for contributions to the Linux kernel.
The text of the DCO is located in the file Documentation/SubmittingPatches (v2.6.12) in the Linux kernel source tree. As of this writing (2008), the certificate of origin is
The full text of the DCO version 1.1 is:
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.
There is a kernel thread discussing the original proposal from Linus here (google groups). And here (aimsgroup).
Here is another article describing rationale for the 1.1 version: Clarifying the Developer's Certificate of Origin KernelTrap, June 14, 2005
Example
Here is an example Signed-off-by line, that indicates the submitter accepts the DCO:
Signed-off-by: John Doe <john.doe@hisdomain.com>
Older versions
The original DCO, version 1.0, read:
Developer's Certificate of Origin 1.0
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.
