The Linux Foundation (LF) is a non-profit technology consortium founded in 2000 as a merger between Open Source Development Labs and the Free Standards Group to standardize Linux, support its growth, and promote its commercial adoption. It also hosts and promotes the collaborative development of open source software projects.[2][3][4] It is a major force in promoting diversity and inclusion in both Linux and the wider open source software community.[5]

It began in 2000, under the Open Source Development Labs (OSDL) and became the organization it is today when OSDL merged with the Free Standards Group (FSG). The Linux Foundation sponsors the work of Linux creator Linus Torvalds and lead maintainer Greg Kroah-Hartman and is supported by members such as AT&T, Cisco, Facebook,[6] Fujitsu, Google, Hitachi, Huawei, IBM, Intel, Microsoft,[7] NEC, Oracle, Orange S.A., Qualcomm, Samsung,[8] Tencent, and VMware, as well as developers from around the world.

In recent years, the Linux Foundation has expanded its support programs through events, training and certification, and open source projects. Projects hosted at the Linux Foundation include the Linux kernel project, Kubernetes, Automotive Grade Linux, Open Network Automation Platform (ONAP), Hyperledger, Cloud Native Computing Foundation, Cloud Foundry Foundation, Xen Project, and many others.

Goals[]

The Linux Foundation is dedicated to building sustainable ecosystems around open source projects to accelerate technology development and commercial adoption. The foundation currently sponsors the work of Linux creator Linus Torvalds and lead maintainer Greg Kroah-Hartman, and aims to provide a neutral home where Linux kernel development can be protected and accelerated.[9]

The foundation also hosts collaborative events among the Linux technical community, software developers, industry, and end users to solve pressing issues facing Linux and open source.[10]

The Linux Foundation supports the Linux community by offering technical information and education through its annual events, such as Open Source Leadership Summit, Linux Kernel Developers Summit, and Open Source Summit (formerly known as LinuxCon,[11] inaugurated in September 2009). A developer travel fund is available.[12]

Initiatives[]

Community Data License Agreement (CDLA)[]

See also: Open Database License

Introduced in October 2017,[13] the Community Data License Agreement (CDLA) is a legal framework for sharing data.[14] There are two initial CDLA licenses:

  • The CDLA-Sharing license was designed to embody the principles of copyleft in a data license. It puts terms in place to ensure that downstream recipients can use and modify that data, and are also required to share their changes to the data.
  • The CDLA-Permissive agreement is similar to permissive open source licenses in that the publisher of data allows anyone to use, modify and do what they want with the data with no obligations to share changes or modifications.

Linux.com[]

On March 3, 2009, the Linux Foundation announced that they would take over the management of Linux.com from its previous owners, SourceForge, Inc.[15]

The site was relaunched on May 13, 2009, shifting away from its previous incarnation as a news site to become a central source for Linux tutorials, information, software, documentation and answers across the server, desktop/netbook, mobile, and embedded areas. It also includes a directory of Linux software and hardware.[16]

Much like Linux itself, Linux.com plans to rely on the community to create and drive the content and conversation.

Linux Foundation Public Health (LFPH)[]

In 2020 amidst the COVID-19 pandemic, the Linux Foundation announced the LFPH,[17] a program dedicated to advancing and supporting the virus contact tracing work led by Google and Apple and their Bluetooth notification systems. The LFPH is focusing its efforts on public health applications, including the effort's first initiative: a notification app intended for governments wanting to launch their privacy-focused exposure notification networks. As of today, LFPF hosts two contact-tracing apps.[18]

LF Climate Finance Foundation[]

In September 2020, The Linux Foundation announced the LF Climate Finance Foundation (LFCF), a new initiative "to encourage investment in AI-enhanced open source analytics to address climate change."[19] LFCF plans to build a platform that will utilize open-source open data to help the financial investment, NGO, and academia sectors to help better model companies’ exposure to climate change.[20] Allianz, Amazon, Microsoft, and S&P Global will be the initiative's founding members.[21]

Training and certification[]

Main article: Linux Foundation Linux Certification

The Linux Foundation Training Program features instructors and content from the leaders of the Linux developer and open source communities.[22]

Participants receive Linux training that is vendor-neutral and created with oversight from leaders of the Linux development community. The Linux Foundation's online and in-person training programs aim to deliver broad, foundational knowledge and networking opportunities.

In March 2014, the Linux Foundation and edX partnered to offer a free massive open online class titled Introduction to Linux.[23] This was the first in a series of ongoing free offerings from both organizations whose current catalogue of MOOCs include Intro to DevOps, Intro to Cloud Foundry and Cloud Native Software Architecture, Intro to Apache Hadoop, Intro to Cloud Infrastructure Technologies, and Intro to OpenStack.[24]

In December 2015, the Linux Foundation introduced a self-paced course designed to help prepare administrators for the OpenStack Foundation's Certified OpenStack Administrator exam.[25]

As part of a partnership with Microsoft, it was announced in December 2015 that the Linux on Azure certification would be awarded to individuals who pass both the Microsoft Exam 70-533 (Implementing Microsoft Azure Infrastructure Solutions) and the Linux Foundation Certified System Administrator (LFCS) exam.[26]

In early 2017, at the annual Open Source Leadership Summit, it was announced that the Linux Foundation would begin offering an Inclusive Speaker Orientation course in partnership with the National Center for Women & Information Technology. The free course is designed to give participants "practical skills to promote inclusivity in their presentations."[27]

In September 2020, the Linux Foundation released a free serverless computing training course with CNCF. It is taught by Alex Ellis, founder of OpenFaaS.[28]

Among many other organization with similar offerings, The Linux Foundation has reported a 40% increase in demand for their online courses in 2020 during the coronavirus pandemic and the resulting social-distancing measures.[29]

Patent Commons Project[]

The patent commons consists of all patented software which has been made available to the open source community. For software to be considered to be in the commons the patent owner must guarantee that developers will not be sued for infringement, though there may be some restrictions on the use of the patented code. The concept was first given substance by Red Hat in 2001 when it published its Patent Promise.[30]

The Patent Commons Project was launched on November 15, 2005, by the Open Source Development Labs (OSDL). The core of the project is an online patent commons reference library aggregating and documenting information about patent-related pledges and other legal solutions directed at the open-source software community. As of 2015, the project listed 53 patents.[31]

Projects[]

Linux Foundation Projects[32] (originally "Collaborative Projects") are independently funded software projects that harness the power of collaborative development to fuel innovation across industries and ecosystems. More than 500 companies and thousands of developers from around the world contribute to these open source software projects.

As of September 2015, the total lines of source code present in Linux Foundation's Collaborative Projects are 115,013,302. The estimated, total amount of effort required to retrace the steps of collaborative development for these projects is 41,192.25 person years. In other words, it would take 1,356 developers 30 years to recreate the code bases. At that time, the total economic value of development costs of Linux Foundation Collaborative Projects was estimated at $5 billion.[33] Through continued investment in open source projects and growth in the number of projects hosted, this number rose to $15.6 billion by September 2017.

All Linux Foundation projects are covered by the Contributor Covenant code of conduct developed by Coraline Ada Ehmke, which is intended to ensure a safe and harassment-free environment for minorities.

Funding[]

Funding for the Linux Foundation comes primarily from its Platinum Members, who pay US$500,000 per year according to Schedule A in LF's bylaws,[123] adding up to US$4 million. The Gold Members contribute a combined total of US$1.6 million, and smaller members less again.

As of April 2014, the foundation collected annual fees worth at least US$6,245,000.

Use of donations[]

Before early 2018, the Linux Foundation's website stated that it "uses [donations] in part to help fund the infrastructure and fellows (like Linus Torvalds) who help develop the Linux kernel."[124]

Events[]

The Linux Foundation events[125] are where the creators, maintainers, and practitioners of the most important open source projects meet. Linux Foundation events in 2017, for example, were expected to attract nearly 25,000 developers, maintainers, system administrators, thought leaders, business executives and other industry professionals from more than 4,000 organizations across 85 countries. Many open source projects also co-locate their events at the Linux Foundation events to take advantage of the cross-community collaboration with projects in the same industry.

2017 events covered various trends in open source, including big data, cloud native, containers, IoT, networking, security, and more.

Linux Foundation events are covered by a comprehensive code of conduct prohibiting inappropriate behavior, including harassment and offensive language. This applies at all times, either before, during or after the event, not only in person but also on social media and any other form of electronic communication. Persons witnessing such behavior are encouraged to report it to conference staff immediately and offenders may face penalties up to and including a lifetime ban from all future events.[126] Additionally, to further improve diversity at events, all-male panels or speaker line-ups are specifically disallowed.[127]

Due to the COVID-19 pandemic, the Linux Foundation has transitioned their events to a digital model until the virus has been successfully managed. The Foundation's largest event, Open Source Summit, was held remotely from June 29 to July 2, 2020 — it had originally been planned to take place in Austin, Texas.[128]
