1 Contributions to hostap.git 2 --------------------------- 3 4 This software is distributed under a permissive open source license to 5 allow it to be used in any projects, whether open source or proprietary. 6 Contributions to the project are welcome and it is important to maintain 7 clear record of contributions and terms under which they are licensed. 8 To help with this, following procedure is used to allow acceptance and 9 recording of the terms. 10 11 All contributions are expected to be licensed under the modified BSD 12 license (see below). Acknowledgment of the terms is tracked through 13 inclusion of Signed-off-by tag in the contributions at the end of the 14 commit log message. This tag indicates that the contributor agrees with 15 the Developer Certificate of Origin (DCO) version 1.1 terms (see below; 16 also available from http://developercertificate.org/). 17 18 19 The current requirements for contributions to hostap.git 20 -------------------------------------------------------- 21 22 To indicate your acceptance of Developer's Certificate of Origin 1.1 23 terms, please add the following line to the end of the commit message 24 for each contribution you make to the project: 25 26 Signed-off-by: Your Name <your (a] email.example.org> 27 28 using your real name. Pseudonyms or anonymous contributions cannot 29 unfortunately be accepted. 30 31 32 The preferred method of submitting the contribution to the project is by 33 email to the hostap mailing list: 34 hostap (a] lists.infradead.org 35 Note that the list may require subscription before accepting message 36 without moderation. You can subscribe to the list at this address: 37 http://lists.infradead.org/mailman/listinfo/hostap 38 39 The message should contain an inlined patch against the current 40 development branch (i.e., the master branch of 41 git://w1.fi/hostap.git). Please make sure the software you use for 42 sending the patch does not corrupt whitespace. If that cannot be fixed 43 for some reason, it is better to include an attached version of the 44 patch file than just send a whitespace damaged version in the message 45 body. 46 47 The patches should be separate logical changes rather than doing 48 everything in a single patch. In other words, please keep cleanup, new 49 features, and bug fixes all in their own patches. Each patch needs a 50 commit log that describes the changes (what the changes fix, what 51 functionality is added, why the changes are useful, etc.). 52 53 Please try to follow the coding style used in the project. 54 55 In general, the best way of generating a suitable formatted patch file 56 is by committing the changes to a cloned git repository and using git 57 format-patch. The patch can then be sent, e.g., with git send-email. 58 59 60 History of license and contributions terms 61 ------------------------------------------ 62 63 Until February 11, 2012, in case of most files in hostap.git, "under the 64 open source license indicated in the file" means that the contribution 65 is licensed both under GPL v2 and modified BSD license (see below) and 66 the choice between these licenses is given to anyone who redistributes 67 or uses the software. As such, the contribution has to be licensed under 68 both options to allow this choice. 69 70 As of February 11, 2012, the project has chosen to use only the BSD 71 license option for future distribution. As such, the GPL v2 license 72 option is no longer used and the contributions are not required to be 73 licensed until GPL v2. In case of most files in hostap.git, "under the 74 open source license indicated in the file" means that the contribution 75 is licensed under the modified BSD license (see below). 76 77 Until February 13, 2014, the project used an extended version of the DCO 78 that included the identical items (a) through (d) from DCO 1.1 and an 79 additional 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 85 This was used during the period when some of the files included the old 86 license terms. Acceptance of this extended DCO version was indicated 87 with a Signed-hostap tag in the commit message. This additional item (e) 88 was used to collect explicit approval to license the contribution with 89 only the modified BSD license (see below), i.e., without the GPL v2 90 option. This was done to allow simpler licensing terms to be used in the 91 future. It should be noted that the modified BSD license is compatible 92 with GNU GPL and as such, this possible move to simpler licensing option 93 does not prevent use of this software in GPL projects. 94 95 96 ===[ start quote from http://developercertificate.org/ ]======================= 97 98 Developer Certificate of Origin 99 Version 1.1 100 101 Copyright (C) 2004, 2006 The Linux Foundation and its contributors. 102 660 York Street, Suite 102, 103 San Francisco, CA 94110 USA 104 105 Everyone is permitted to copy and distribute verbatim copies of this 106 license document, but changing it is not allowed. 107 108 109 Developer's Certificate of Origin 1.1 110 111 By 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/ ]========================= 136 137 138 The license terms used for hostap.git files 139 ------------------------------------------- 140 141 Modified BSD license (no advertisement clause): 142 143 Copyright (c) 2002-2017, Jouni Malinen <j (a] w1.fi> and contributors 144 All Rights Reserved. 145 146 Redistribution and use in source and binary forms, with or without 147 modification, are permitted provided that the following conditions are 148 met: 149 150 1.
