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 32The preferred method of submitting the contribution to the project is by 33email to the hostap mailing list: 34hostap@lists.infradead.org 35Note that the list may require subscription before accepting message 36without moderation. You can subscribe to the list at this address: 37http://lists.infradead.org/mailman/listinfo/hostap 38 39The message should contain an inlined patch against the current 40development branch (i.e., the master branch of 41git://w1.fi/hostap.git). Please make sure the software you use for 42sending the patch does not corrupt whitespace. If that cannot be fixed 43for some reason, it is better to include an attached version of the 44patch file than just send a whitespace damaged version in the message 45body. 46 47The patches should be separate logical changes rather than doing 48everything in a single patch. In other words, please keep cleanup, new 49features, and bug fixes all in their own patches. Each patch needs a 50commit log that describes the changes (what the changes fix, what 51functionality is added, why the changes are useful, etc.). 52 53Please try to follow the coding style used in the project. 54 55In general, the best way of generating a suitable formatted patch file 56is by committing the changes to a cloned git repository and using git 57format-patch. The patch can then be sent, e.g., with git send-email. 58 59 60History of license and contributions terms 61------------------------------------------ 62 63Until February 11, 2012, in case of most files in hostap.git, "under the 64open source license indicated in the file" means that the contribution 65is licensed both under GPL v2 and modified BSD license (see below) and 66the choice between these licenses is given to anyone who redistributes 67or uses the software. As such, the contribution has to be licensed under 68both options to allow this choice. 69 70As of February 11, 2012, the project has chosen to use only the BSD 71license option for future distribution. As such, the GPL v2 license 72option is no longer used and the contributions are not required to be 73licensed until GPL v2. In case of most files in hostap.git, "under the 74open source license indicated in the file" means that the contribution 75is licensed under the modified BSD license (see below). 76 77Until February 13, 2014, the project used an extended version of the DCO 78that included the identical items (a) through (d) from DCO 1.1 and an 79additional item (e): 80 81(e) The contribution can be licensed under the modified BSD license 82 as shown below even in case of files that are currently licensed 83 under other terms. 84 85This was used during the period when some of the files included the old 86license terms. Acceptance of this extended DCO version was indicated 87with a Signed-hostap tag in the commit message. This additional item (e) 88was used to collect explicit approval to license the contribution with 89only the modified BSD license (see below), i.e., without the GPL v2 90option. This was done to allow simpler licensing terms to be used in the 91future. It should be noted that the modified BSD license is compatible 92with GNU GPL and as such, this possible move to simpler licensing option 93does not prevent use of this software in GPL projects. 94 95 96===[ start quote from http://developercertificate.org/ ]======================= 97 98Developer Certificate of Origin 99Version 1.1 100 101Copyright (C) 2004, 2006 The Linux Foundation and its contributors. 102660 York Street, Suite 102, 103San Francisco, CA 94110 USA 104 105Everyone is permitted to copy and distribute verbatim copies of this 106license document, but changing it is not allowed. 107 108 109Developer's Certificate of Origin 1.1 110 111By making a contribution to this project, I certify that: 112 113(a) The contribution was created in whole or in part by me and I 114 have the right to submit it under the open source license 115 indicated in the file; or 116 117(b) The contribution is based upon previous work that, to the best 118 of my knowledge, is covered under an appropriate open source 119 license and I have the right under that license to submit that 120 work with modifications, whether created in whole or in part 121 by me, under the same open source license (unless I am 122 permitted to submit under a different license), as indicated 123 in the file; or 124 125(c) The contribution was provided directly to me by some other 126 person who certified (a), (b) or (c) and I have not modified 127 it. 128 129(d) I understand and agree that this project and the contribution 130 are public and that a record of the contribution (including all 131 personal information I submit with it, including my sign-off) is 132 maintained indefinitely and may be redistributed consistent with 133 this project or the open source license(s) involved. 134 135===[ end quote from http://developercertificate.org/ ]========================= 136 137 138The license terms used for hostap.git files 139------------------------------------------- 140 141Modified BSD license (no advertisement clause): 142 143Copyright (c) 2002-2016, Jouni Malinen <j@w1.fi> and contributors 144All Rights Reserved. 145 146Redistribution and use in source and binary forms, with or without 147modification, are permitted provided that the following conditions are 148met: 149 1501.
