Acknowledgment of the terms is tracked through +inclusion of Signed-off-by tag in the contributions at the end of the +commit log message.

Pseudonyms or anonymous contributions cannot +unfortunately be accepted. + + +History of license and contributions terms +------------------------------------------ + +Until February 11, 2012, in case of most files in hostap.git, "under the +open source license indicated in the file" means that the contribution +is licensed both under GPL v2 and modified BSD license (see below) and +the choice between these licenses is given to anyone who redistributes +or uses the software.

As such, the GPL v2 license +option is no longer used and the contributions are not required to be +licensed until GPL v2. In case of most files in hostap.git, "under the +open source license indicated in the file" means that the contribution +is licensed under the modified BSD license (see below). + +Until February 13, 2014, the project used an extended version of the DCO +that included the identical items (a) through (d) from DCO 1.1 and an +additional item (e): + +(e) The contribution can be licensed under the modified BSD license + as shown below even in case of files that are currently licensed + under other terms. + +This was used during the period when some of the files included the old +license terms.

This additional item (e) +was used to collect explicit approval to license the contribution with +only the modified BSD license (see below), i.e., without the GPL v2 +option. This was done to allow simpler licensing terms to be used in the +future. It should be noted that the modified BSD license is compatible +with GNU GPL and as such, this possible move to simpler licensing option +does not prevent use of this software in GPL projects. + + +===[ start quote from http://developercertificate.org/ ]======================= + +Developer Certificate of Origin +Version 1.1 + +Copyright (C) 2004, 2006 The Linux Foundation and its contributors. +660 York Street, Suite 102, +San Francisco, CA 94110 USA + +Everyone is permitted to copy and distribute verbatim copies of this +license document, but changing it is not allowed. + + +Developer's Certificate of Origin 1.1 + +By making a contribution to this project, I certify that: + +(a) The contribution was created in whole or in part by me and I + have the right to submit it under the open source license + indicated in the file; or + +(b) The contribution is based upon previous work that, to the best + of my knowledge, is covered under an appropriate open source + license and I have the right under that license to submit that + work with modifications, whether created in whole or in part + by me, under the same open source license (unless I am + permitted to submit under a different license), as indicated + in the file; or + +(c) The contribution was provided directly to me by some other + person who certified (a), (b) or (c) and I have not modified + it. + +(d) I understand and agree that this project and the contribution + are public and that a record of the contribution (including all + personal information I submit with it, including my sign-off) is + maintained indefinitely and may be redistributed consistent with + this project or the open source license(s) involved. + +===[ end quote from http://developercertificate.org/ ]========================= + + +The license terms used for hostap.git files +------------------------------------------- + +Modified BSD license (no advertisement clause): + +Copyright (c) 2002-2015, Jouni Malinen and contributors +All Rights Reserved. + +Redistribution and use in source and binary forms, with or without +modification, are permitted provided that the following conditions are +met: + +1.

The RADIO_WORK control interface command can be used for this. + +"RADIO_WORK add [freq=] [timeout=]" command can be +used to reserve a slot for radio access. If freq is specified, other +radio work items on the same channel may be completed in +parallel. Otherwise, all other radio work items are blocked during +execution. Timeout is set to 10 seconds by default to avoid blocking +wpa_supplicant operations for excessive time. If a longer (or shorter) +safety timeout is needed, that can be specified with the optional +timeout parameter. This command returns an identifier for the radio work +item. + +Once the radio work item has been started, "EXT-RADIO-WORK-START " +event message is indicated that the external processing can start. Once +the operation has been completed, "RADIO_WORK done " is used to +indicate that to wpa_supplicant. This allows other radio works to be +performed.
