Orivex Syscall Note License

SPDX-License-Identifier: Orivex-syscall-note ORIVEX SYSCALL NOTE LICENSE (OSN-1.0) Copyright (c) 2025 Kartik Preamble -------- The Orivex Syscall Note License (OSN-1.0) is a permissive open-source license tailored for kernel-facing artifacts such as kernel headers, syscall interface definitions, reference ABI documentation, and related API files (collectively, the "Software"). OSN-1.0 seeks to: (a) provide broad, unencumbered rights to use, modify, and redistribute the Software; (b) preserve attribution and provenance of kernel interface definitions and ABI contracts; (c) encourage upstream compatibility and traceability of changes to syscall interfaces; (d) protect Orivex trademarks and identity by separating trademark rights from copyright and patent grants; and (e) clarify contributor patent grants and termination on patent litigation. 1. Definitions -------------- In this License: 1.1 "You" (or "Your") means any individual or legal entity exercising Rights under this License. 1.2 "Licensor" means the copyright holder(s) identified at the top of this document or any entity that subsequently holds copyright in the Software and distributes it under OSN-1.0. 1.3 "Contributor" means any individual or legal entity that submits Contributions to the Software. 1.4 "Contribution" means any original work of authorship, including modifications and additions, submitted to the Software and intentionally contributed by You to the Licensor for inclusion in the Software. 1.5 "Derivative Work" has the meaning given by applicable law, and includes works that incorporate or are based upon the Software. 1.6 "Distribution" means any transfer, conveyance, sale, sublicense, lease, or public offering of the Software or derivative works thereof, in source or binary/object form. 1.7 "Notice File" means a file named SYSCALL-LICENSE.md or NOTICE, or other similarly prominent file, used to communicate attribution, license terms, or other required notices to recipients of the Software. 1.8 "Binary Form" means object code or any form other than readable source code. 1.9 "Source Form" means the preferred form for making modifications, including but not limited to original source code, documentation source, and build scripts. 2.

Subject to the terms of this License, the Licensor grants You a worldwide, royalty-free, non-exclusive, perpetual patent license under Licensor-owned patents to make, use, sell, offer to sell, import, and otherwise distribute the Software, but only to the extent such patent claims are necessarily infringed by the Software as delivered by the Licensor. 3.2 Patent Grant by Contributor. By making a Contribution, each Contributor hereby grants You a worldwide, royalty-free, non-exclusive, perpetual patent license under any patent claims that are necessarily infringed by their Contribution alone or by the Contribution when combined with the Software submitted to the Licensor. 3.3 Termination for Patent Litigation. If You (or any entity controlled by You) institutes or causes to be instituted any patent litigation (including a cross-claim or counterclaim) against any party alleging that the Software or a Contribution infringes a patent, then any patent licenses granted to You under Sections 3.1 or 3.2 for the Software shall terminate as to the party to whom such license was granted. 4. Redistribution: Source and Binary Requirements ------------------------------------------------ Redistributions of the Software, in Source or Binary Form, must meet the following: 4.1 License Copy. Redistributions must include a complete, unmodified copy of this OSN-1.0 License text or a machine-readable reference to it (for Binary Form), and the SPDX identifier where feasible. 4.2 Copyright and Notices. Redistributions must retain, in all source files and in any distributed NOTICE or SYSCALL-LICENSE.md file, all copyright, patent, and attribution notices that appear in the Software. 4.3 Prominent Attribution Note. Redistributions must include in a prominent location (for example a top-level README, NOTICE, or SYSCALL-LICENSE.md) the statement: "This distribution includes Orivex syscall interfaces (OSN-1.0). See SYSCALL-LICENSE.md or NOTICE for details." 4.4 SYSCALL-CHANGES.md. If You modify files covered by the Software, You must include a SYSCALL-CHANGES.md documenting the nature of changes (short summary, author, and date) and distribute it alongside the modified files. This requirement is for provenance and traceability and does not otherwise limit Your rights to modify or distribute. 4.5 Binary Form. For Binary Form redistributions, You must reproduce the information required by Sections 4.1–4.4 in a NOTICE or equivalent documentation distributed with the Binary (e.g., in a top-level directory, installer, or package metadata). 4.6 Sublicensing. You may grant sublicenses to downstream recipients, provided sublicenses preserve the requirements of this License with respect to the portions of the Software covered by OSN-1.0. 5.

Compatibility and Stability Guidance --------------------------------------- 6.1 Compatibility Encouragement. The Licensor strongly encourages contributors and downstream redistributors to preserve ABI and syscall interface compatibility where possible. 6.2 Deprecation and Breaking Changes. Where a change breaks compatibility, the party making the change should document the change, provide an upstream notice, and, where reasonably practicable, offer a deprecation period sufficient to allow downstream projects to adapt. 6.3 Not a License Obligation. The guidance in this Section 6 is non-binding and intended to encourage cooperative development; it does not create legal obligations beyond those expressly stated in other sections of this License. 7. Trademarks, Name & Logos --------------------------- 7.1 No Trademark Grant. This License does not grant permission to use trade names, trademarks, service marks, logos, or product names of the Licensor, except as required solely to identify the origin of the Software in notices as required by Section 4.3. 7.2 Referencing the Orivex Name. You may refer to the Software as "Orivex syscall interfaces" for identification and compatibility descriptions, provided such references do not imply endorsement by the Orivex project or use of Orivex trademarks beyond the limited attribution permitted by Section 4.3. 7.3 Separate Trademark Policies. The Licensor may publish separate trademark usage guidelines; compliance with such guidelines is required to make use of Orivex trademarks beyond the attribution described above. 8.

Termination --------------- 11.1 Automatic Termination. Your rights under this License will terminate automatically if You fail to comply with any of its terms and fail to cure such non-compliance within thirty (30) days of receiving written notice from the Licensor; provided that termination of Your rights will not terminate rights that have already been granted by You to third parties if those third parties received the Software lawfully and in compliance with this License. 11.2 Effect of Termination.
