1Contributions to hostap.git 2--------------------------- 3 4This software is distributed under a permissive open source license to 5allow it to be used in any projects, whether open source or proprietary. 6Contributions to the project are welcome and it is important to maintain 7clear record of contributions and terms under which they are licensed. 8To help with this, following procedure is used to allow acceptance and 9recording of the terms. 10 11All contributions are expected to be licensed under the modified BSD 12license (see below). Acknowledgment of the terms is tracked through 13inclusion of Signed-off-by tag in the contributions at the end of the 14commit log message. This tag indicates that the contributor agrees with 15the Developer Certificate of Origin (DCO) version 1.1 terms (see below; 16also available from http://developercertificate.org/). 17 18 19The current requirements for contributions to hostap.git 20-------------------------------------------------------- 21 22To indicate your acceptance of Developer's Certificate of Origin 1.1 23terms, please add the following line to the end of the commit message 24for each contribution you make to the project: 25 26Signed-off-by: Your Name <your@email.example.org> 27 28using your real name. Pseudonyms or anonymous contributions cannot 29unfortunately be accepted. 30 31 32History of license and contributions terms 33------------------------------------------ 34 35Until February 11, 2012, in case of most files in hostap.git, "under the 36open source license indicated in the file" means that the contribution 37is licensed both under GPL v2 and modified BSD license (see below) and 38the choice between these licenses is given to anyone who redistributes 39or uses the software. As such, the contribution has to be licensed under 40both options to allow this choice. 41 42As of February 11, 2012, the project has chosen to use only the BSD 43license option for future distribution. As such, the GPL v2 license 44option is no longer used and the contributions are not required to be 45licensed until GPL v2. In case of most files in hostap.git, "under the 46open source license indicated in the file" means that the contribution 47is licensed under the modified BSD license (see below). 48 49Until February 13, 2014, the project used an extended version of the DCO 50that included the identical items (a) through (d) from DCO 1.1 and an 51additional item (e): 52 53(e) The contribution can be licensed under the modified BSD license 54 as shown below even in case of files that are currently licensed 55 under other terms. 56 57This was used during the period when some of the files included the old 58license terms. Acceptance of this extended DCO version was indicated 59with a Signed-hostap tag in the commit message. This additional item (e) 60was used to collect explicit approval to license the contribution with 61only the modified BSD license (see below), i.e., without the GPL v2 62option. This was done to allow simpler licensing terms to be used in the 63future. It should be noted that the modified BSD license is compatible 64with GNU GPL and as such, this possible move to simpler licensing option 65does not prevent use of this software in GPL projects. 66 67 68===[ start quote from http://developercertificate.org/ ]======================= 69 70Developer Certificate of Origin 71Version 1.1 72 73Copyright (C) 2004, 2006 The Linux Foundation and its contributors. 74660 York Street, Suite 102, 75San Francisco, CA 94110 USA 76 77Everyone is permitted to copy and distribute verbatim copies of this 78license document, but changing it is not allowed. 79 80 81Developer's Certificate of Origin 1.1 82 83By making a contribution to this project, I certify that: 84 85(a) The contribution was created in whole or in part by me and I 86 have the right to submit it under the open source license 87 indicated in the file; or 88 89(b) The contribution is based upon previous work that, to the best 90 of my knowledge, is covered under an appropriate open source 91 license and I have the right under that license to submit that 92 work with modifications, whether created in whole or in part 93 by me, under the same open source license (unless I am 94 permitted to submit under a different license), as indicated 95 in the file; or 96 97(c) The contribution was provided directly to me by some other 98 person who certified (a), (b) or (c) and I have not modified 99 it. 100 101(d) I understand and agree that this project and the contribution 102 are public and that a record of the contribution (including all 103 personal information I submit with it, including my sign-off) is 104 maintained indefinitely and may be redistributed consistent with 105 this project or the open source license(s) involved. 106 107===[ end quote from http://developercertificate.org/ ]========================= 108 109 110The license terms used for hostap.git files 111------------------------------------------- 112 113Modified BSD license (no advertisement clause): 114 115Copyright (c) 2002-2014, Jouni Malinen <j@w1.fi> and contributors 116All Rights Reserved. 117 118Redistribution and use in source and binary forms, with or without 119modification, are permitted provided that the following conditions are 120met: 121 1221.
