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 History of license and contributions terms 33 ------------------------------------------ 34 35 Until February 11, 2012, in case of most files in hostap.git, "under the 36 open source license indicated in the file" means that the contribution 37 is licensed both under GPL v2 and modified BSD license (see below) and 38 the choice between these licenses is given to anyone who redistributes 39 or uses the software. As such, the contribution has to be licensed under 40 both options to allow this choice. 41 42 As of February 11, 2012, the project has chosen to use only the BSD 43 license option for future distribution. As such, the GPL v2 license 44 option is no longer used and the contributions are not required to be 45 licensed until GPL v2. In case of most files in hostap.git, "under the 46 open source license indicated in the file" means that the contribution 47 is licensed under the modified BSD license (see below). 48 49 Until February 13, 2014, the project used an extended version of the DCO 50 that included the identical items (a) through (d) from DCO 1.1 and an 51 additional 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 57 This was used during the period when some of the files included the old 58 license terms. Acceptance of this extended DCO version was indicated 59 with a Signed-hostap tag in the commit message. This additional item (e) 60 was used to collect explicit approval to license the contribution with 61 only the modified BSD license (see below), i.e., without the GPL v2 62 option. This was done to allow simpler licensing terms to be used in the 63 future. It should be noted that the modified BSD license is compatible 64 with GNU GPL and as such, this possible move to simpler licensing option 65 does not prevent use of this software in GPL projects. 66 67 68 ===[ start quote from http://developercertificate.org/ ]======================= 69 70 Developer Certificate of Origin 71 Version 1.1 72 73 Copyright (C) 2004, 2006 The Linux Foundation and its contributors. 74 660 York Street, Suite 102, 75 San Francisco, CA 94110 USA 76 77 Everyone is permitted to copy and distribute verbatim copies of this 78 license document, but changing it is not allowed. 79 80 81 Developer's Certificate of Origin 1.1 82 83 By 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/ ]========================= 108 109 110 The license terms used for hostap.git files 111 ------------------------------------------- 112 113 Modified BSD license (no advertisement clause): 114 115 Copyright (c) 2002-2014, Jouni Malinen <j (a] w1.fi> and contributors 116 All Rights Reserved. 117 118 Redistribution and use in source and binary forms, with or without 119 modification, are permitted provided that the following conditions are 120 met: 121 122 1.
