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 59A list of pending patches waiting for review is available in 60Patchwork: https://patchwork.ozlabs.org/project/hostap/list/ 61 62 63History of license and contributions terms 64------------------------------------------ 65 66Until February 11, 2012, in case of most files in hostap.git, "under the 67open source license indicated in the file" means that the contribution 68is licensed both under GPL v2 and modified BSD license (see below) and 69the choice between these licenses is given to anyone who redistributes 70or uses the software. As such, the contribution has to be licensed under 71both options to allow this choice. 72 73As of February 11, 2012, the project has chosen to use only the BSD 74license option for future distribution. As such, the GPL v2 license 75option is no longer used and the contributions are not required to be 76licensed until GPL v2. In case of most files in hostap.git, "under the 77open source license indicated in the file" means that the contribution 78is licensed under the modified BSD license (see below). 79 80Until February 13, 2014, the project used an extended version of the DCO 81that included the identical items (a) through (d) from DCO 1.1 and an 82additional item (e): 83 84(e) The contribution can be licensed under the modified BSD license 85 as shown below even in case of files that are currently licensed 86 under other terms. 87 88This was used during the period when some of the files included the old 89license terms. Acceptance of this extended DCO version was indicated 90with a Signed-hostap tag in the commit message. This additional item (e) 91was used to collect explicit approval to license the contribution with 92only the modified BSD license (see below), i.e., without the GPL v2 93option. This was done to allow simpler licensing terms to be used in the 94future. It should be noted that the modified BSD license is compatible 95with GNU GPL and as such, this possible move to simpler licensing option 96does not prevent use of this software in GPL projects. 97 98 99===[ start quote from http://developercertificate.org/ ]======================= 100 101Developer Certificate of Origin 102Version 1.1 103 104Copyright (C) 2004, 2006 The Linux Foundation and its contributors. 105660 York Street, Suite 102, 106San Francisco, CA 94110 USA 107 108Everyone is permitted to copy and distribute verbatim copies of this 109license document, but changing it is not allowed. 110 111 112Developer's Certificate of Origin 1.1 113 114By making a contribution to this project, I certify that: 115 116(a) The contribution was created in whole or in part by me and I 117 have the right to submit it under the open source license 118 indicated in the file; or 119 120(b) The contribution is based upon previous work that, to the best 121 of my knowledge, is covered under an appropriate open source 122 license and I have the right under that license to submit that 123 work with modifications, whether created in whole or in part 124 by me, under the same open source license (unless I am 125 permitted to submit under a different license), as indicated 126 in the file; or 127 128(c) The contribution was provided directly to me by some other 129 person who certified (a), (b) or (c) and I have not modified 130 it. 131 132(d) I understand and agree that this project and the contribution 133 are public and that a record of the contribution (including all 134 personal information I submit with it, including my sign-off) is 135 maintained indefinitely and may be redistributed consistent with 136 this project or the open source license(s) involved. 137 138===[ end quote from http://developercertificate.org/ ]========================= 139 140 141The license terms used for hostap.git files 142------------------------------------------- 143 144Modified BSD license (no advertisement clause): 145 146Copyright (c) 2002-2022, Jouni Malinen <j@w1.fi> and contributors 147All Rights Reserved. 148 149Redistribution and use in source and binary forms, with or without 150modification, are permitted provided that the following conditions are 151met: 152 1531.
