License And Contribution Policy

Fuego has the following license policy.

Fuego consists of several parts, and includes source code from a number of different external test projects.

Default license [edit section]

The default license for Fuego is the BSD 3-Clause license, as indicated in the LICENSE file at the top of the 'fuego' and 'fuego-core' source repositories.

If a file does not have an explicit license, or license indicator (such as SPDX identifier) in the file, than that file is covered by the default license for the project, with the exceptions noted below for "external test materials".

When making contributions, if you do NOT indicate an alternative license for your contribution, the contribution will be assigned the license of the file to which the contribution applies (which may be the default license, if the file contains no existing license indicator).

Although we may allow for other licenses within the Fuego project in order to accommodate external software added to our system, our preference is to avoid the proliferation of licenses in the Fuego code itself.

external test materials [edit section]

Individual tests in Fuego consist of files in the directory: engine/tests/<test_name> (which is known as the test home directory), and may include two types of materials:
  • 1) Fuego-specific files
  • 2) files obtained from external sources, which have their own license.

The Fuego-specific materials consist of files such as:, spec.json, reference.json, test.yaml, chart_config.json, and possibly others as created for use in the Fuego project. External test materials may consist of tar files, helper scripts and patches against the source in the tar files.

Unless otherwise indicated, the Fuego-specific materials are licensed under the Fuego default license, and the external test materials are licensed under their own individual project license - as indicated in the test source.

In some cases, there is no external source code, but only source that is originally written for Fuego and stored in the test home directory. This commonly includes tests based on a single shell script, that is written to be deployed to the Device Under Test by Unless otherwise indicated, these files (source and scripts) are licensed under the Fuego default license.

If there is any ambiguity in the category of a particular file (external or Fuego-specific), please designate the intended license clearly in the file itself, when making a contribution.

Copyright statements [edit section]

Copyrights for individual contributions should be added to individual files, when the contributions warrant copyright assignment. Some trivial fixes to existing code may not need to have copyright assignment, and thus not every change to a file needs to include a copyright notice for the contributor.

Contributor agreement [edit section]

The Fuego project does not require a signed Contributor License Agreement for contribution to the project. Instead, we utilize the following Developer Certificate of Origin that was copied from the Linux kernel.

Each contribution to Fuego must be accompanied by a Signed-off-by line in the patch or commit description, which indicates agreement to the following:

    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
            (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.

Note: Please note that an "official" DCO at the web site has additional text (an LF copyright, address, and statement of non-copyability). All of these are either nonsense or problematical in some legal sense. The above is a quote of a portion of the document found in the Linux kernel guide for submitting patches. See (copied in March, 2018).

Each commit must include a DCO which looks like this

   Signed-off-by: Joe Smith <>

The project requires that the name used is your real name. Neither anonymous contributors nor those utilizing pseudonyms will be accepted.

You may type this line on your own when writing your commit messages. However, Git makes it easy to add this line to your commit messages. Make sure the and are set in your git configs. Use '-s' or '--signoff' options to 'git commit' to add the Signed-off-by line to the end of the commit message.
