A German Linux programmer has obtained a preliminary injunction against United States security firm Fortinet for violating the General Public Licence (GPL) that governs the legal distribution of open-source software such as Linux.
Harald Welte, who runs website gpl-violations.org, accused the firm of using cryptographic techniques to conceal Linux code in its FortiGate and FortiWifi products and not releasing its source code under the terms of the GPL.
Open-source software is free for anybody to use provided they include the source code in the release. The case highlights the risk facing companies of violating software licensing agreements by mixing their proprietary code with software governed by the GPL or other open-source licences.
Most companies guard their own source code the way Coca-Cola guards the formula for its famous drink.
Fortinet director of public relations Michelle Splover said all issues had been rectified. 'Fortinet has actively taken steps to ensure that its products are compliant with GPL requirements and is continuing its efforts to expeditiously resolve this matter with Mr Welte. All new Fortinet product shipments now include a modified end-user licence agreement and GPL licensing agreement, thereby making [comply with] GPL requirements.'
Mr Welte said the legal action was to make the company comply with the rules: to 'make sure that all products and firmware updates are distributed in compliance with the GPL worldwide immediately'.
