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. All contributions are expected to be licensed under the modified BSD license (see below). Acknowledgment of the terms is tracked through inclusion of Signed-off-by tag in the contributions at the end of the commit log message. This tag indicates that the contributor agrees with the Developer Certificate of Origin (DCO) version 1.1 terms (see below; also available from http://developercertificate.org/). The current requirements for contributions to hostap.git -------------------------------------------------------- To indicate your acceptance of Developer's Certificate of Origin 1.1 terms, please add the following line to the end of the commit message for each contribution you make to the project: Signed-off-by: Your Name using your real name. Pseudonyms or anonymous contributions cannot unfortunately be accepted. The preferred method of submitting the contribution to the project is by email to the hostap mailing list: hostap@lists.infradead.org Note that the list may require subscription before accepting message without moderation. You can subscribe to the list at this address: http://lists.infradead.org/mailman/listinfo/hostap The message should contain an inlined patch against the current development branch (i.e., the master branch of git://w1.fi/hostap.git). Please make sure the software you use for sending the patch does not corrupt whitespace. If that cannot be fixed for some reason, it is better to include an attached version of the patch file than just send a whitespace damaged version in the message body. The patches should be separate logical changes rather than doing everything in a single patch. In other words, please keep cleanup, new features, and bug fixes all in their own patches. Each patch needs a commit log that describes the changes (what the changes fix, what functionality is added, why the changes are useful, etc.). Please try to follow the coding style used in the project. In general, the best way of generating a suitable formatted patch file is by committing the changes to a cloned git repository and using git format-patch. The patch can then be sent, e.g., with git send-email. History of license and contributions terms ------------------------------------------ Until February 11, 2012, 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. As of February 11, 2012, the project has chosen to use only the BSD license option for future distribution. As such, the GPL v2 license option is no longer used and the contributions are not required to be licensed until GPL v2. In case of most files in hostap.git, "under the open source license indicated in the file" means that the contribution is licensed under the modified BSD license (see below). Until February 13, 2014, the project used an extended version of the DCO that included the identical items (a) through (d) from DCO 1.1 and an additional item (e): (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. This was used during the period when some of the files included the old license terms. Acceptance of this extended DCO version was indicated with a Signed-hostap tag in the commit message. This additional item (e) was 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 was 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 GPL projects. ===[ start quote from http://developercertificate.org/ ]======================= Developer Certificate of Origin Version 1.1 Copyright (C) 2004, 2006 The Linux Foundation and its contributors. 660 York Street, Suite 102, San Francisco, CA 94110 USA Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed.
