I'm planning on introducing a more formal procedure for tracking
contributions to hostap.git (wpa_supplicant, hostapd, and any other
related files in the repository). The goal here is to minimize any
possibility of misunderstanding or confusion on the exact terms under
which the contributions need to be licensed under and to record explicit
acceptance of the terms. Similar expectations on contributions have been
in place in the past, but the process for confirming this for each
contribution has been less formal.
If you are familiar with development process used with the Linux kernel,
you'll find this to be very similar, but there are some additional
clarifications to cover the different licensing model used in
Please let me know if you have any questions or concerns on this. I'm
requesting all new contributions to follow the described process and I'm
planning on starting to enforce this eventually for anything committed
The latest version of the description is in the CONTRIBUTIONS file at
the top level of hostap.git which can also be viewed through the gitweb
I'm included the current version of that file below:
Contributions to hostap.git
This software is distributed under a permissive open source license to
allow it to be used in any projects, whether open source or proprietary.
Contributions to the project are welcome and it is important to maintain
clear record of contributions and terms under which they are licensed.
To help with this, following procedure is used to allow acceptance and
recording of the terms.
These terms are similar to the process used in Linux kernel development.
The items (a) through (d) are identical to the Developer's Certificate
of Origin 1.1. To enable cleaner licensing option to be provided in the
future, an additional item (e) is included.
In case of most files in hostap.git, "under the open source license
indicated in the file" means that the contribution is licensed both
under GPL v2 and modified BSD license (see below) and the choice between
these licenses is given to anyone who redistributes or uses the
software. As such, the contribution has to be licensed under both
options to allow this choice.
The additional item (e) is used to collect explicit approval to license
the contribution with only the modified BSD license (see below), i.e.,
without the GPL v2 option. This is done to allow simpler licensing terms
to be used in the future. It should be noted that the modified BSD
license is compatible with GNU GPL and as such, this possible move to
simpler licensing option does not prevent use of this software in
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.
Additionally, I certify that:
(e) The contribution can be licensed under the modified BSD license
as shown below even in case of files that are currently licensed
under other terms.
To indicate your acceptance of these terms, please add the following
line to each contribution you make to the project:
Signed-hostap: Your Name <your at email.example.org>
using your real name. Pseudonyms or anonymous contributions cannot
unfortunately be accepted.
