<p>The GPL Compliance Project for Linux Developers is comprised of copyright

holders in the kernel, Linux, who have contributed to Linux under its

license, <a href="http://www.gnu.org/licenses/gpl-2.0.html">the

GPLv2</a>. These copyright holders have formally asked Conservancy to engage

in compliance efforts for their copyrights in the Linux kernel.</p>

<p>Historically, Conservancy was well-known for its ongoing license

compliance efforts on behalf of its BusyBox member project.  In May

2012, <a href="https://sfconservancy.org/news/2012/may/29/compliance/">Conservancy

announced a coordinated compliance effort</a> on behalf of its BusyBox and

Samba projects, and also launched this unique project, called the <cite>GPL

Compliance Project for Linux Developers</cite>, which handles compliance and

enforcement activities on behalf of more than a dozen Linux copyright

holders.</p>

<p>Conservancy's GPL Compliance Project is run in a collaborative manner with

the project developers.  All copyright holders involved have the opportunity

to give input and guidance on Conservancy's strategy in dealing with

compliance issues.  Thus, all Conservancy's compliance matter have full

support of relevant copyright holders.</p>

<p>Conservancy is dedicated to encouraging all users of software to comply

  with Free Software licenses. Toward this goal, in its compliance efforts,

  Conservancy helps distributors of Free Software in a friendly spirit of

  cooperation and participation.  In this spirit, Conservancy also sponsors

  the <a href="https://copyleft.org/guide/"><cite>Copyleft and the GNU

  General Public License:A Comprehensive Tutorial and Guide</cite></a>, in

  collaboration with the Free Software Foundation (FSF),

  which <a href="/news/2014/nov/07/copyleft-org/">Conservancy formally

  launched in fall 2014</a>.  The Guide includes tutorial materials about

  copyleft and compliance with copyleft licenses,

  including <a href="https://copyleft.org/guide/comprehensive-gpl-guidepa2.html"><cite>A

  Practical Guide to GPL Compliance</cite></a>.  The materials

  on <a href="https://copyleft.org/">copyleft.org</a> have been developed and

  improved since 2002, and are themselves copylefted, and developed

  collaboratively in public.</p>

<p>However, the Guide is admittedly a large document, so for those who are

  interested in a short summary of describing how Conservancy handles GPL

  enforcement and compliance

  work, <a href="https://sfconservancy.org/blog/2012/feb/01/gpl-enforcement/">this

  blog post outlining the compliance process</a> is likely the best source.</p>

<p>If you are aware of a license violation or compliance issue regarding

  Linux, or

<h2>The time has come to stand up for the GPL.</h2>

<p><em>Last month, Conservancy <a href="/news/2015/mar/05/vmware-lawsuit/">announced Christoph Hellwig's

    lawsuit against VMware in Germany</a>.  Help us meet our anonymous match to 

    support Conservancy's and Christoph's efforts in this area

    by <a href="https://sfconservancy.org/supporter/">becoming a Conservancy

    supporter</a> or <a href="#donate-box" class="donate-now">donating via

    the link on the right</a>.</em></p>

<p>We were told to ask nicely and repeatedly, so we did.</p>

<p>We asked allies to help us make contact in friendly and professional

  ways.</p>

<p>Everyone asked us to give companies as many chances as possible and as

  much help as possible to comply with copyleft, so we did.</p>

<p>We've worked for years to help VMware comply with the GPL, but they

refuse. Negotiations broke down for the last time when they insisted on an 

NDA just to discuss settlement terms!</p>

<p>Christoph is among the most active developers of Linux.  As of Feburary 

19, 2015, Christoph has contributed 279,653 lines of code to the Linux kernel, 

and ranks 20th among the 1,340 developers involved in the latest 3.19 kernel 

release.  Christoph also

ranks 4th among those who have reviewed third-party source code, tirelessly

corrected and commented on other developers' contributions.  Christoph

licenses his code to the public under the terms of the GPL for practical and

ideological reasons.  VMware, a company with net revenue of over $1 billion

and over 14,000 employees, ignored Christoph's choice.  They took Christoph's

code from Linux and modified it to work with their own kernel without releasing

source code of the resulting complete work.  This is precisely the kind of

activity Christoph and other kernel developers seek to prevent by choosing

the GPL.  The GPL was written to prevent this specific scenario!</p>

<h3>This is a matter of principle.</h3>

<p>Free and open source software is everywhere and in everything; yet our

  software freedom is constantly eroded.</p>

<p>We want companies to incorporate our software into new products, but there

are a few simple rules.  Copylefted free software is so prevalent because

there's no way a company can compete without using a significant amount of

free software to bring products to market in reasonable time. They get so

much benefit from our work.  Allowing the whole community to review, use,

<h1>Frequently Asked Questions about Christoph Hellwig's VMware Lawsuit</h1>

<p>Conservancy maintains this

  <abbr title="Frequently Asked Questions">FAQ</abbr> list regarding

  <a href="/news/2015/mar/05/vmware-lawsuit/">Christoph Hellwig's lawsuit against VMware

  in Germany over alleged GPL violations on Linux</a> as a service to the

  Free Software community, and in particular, the copyleft community.  Conservancy

  realizes this lawsuit generates many questions and interest

  from the community.  Legal counsel (both Conservancy's own, and

  Christoph's lawyer, Till Jaeger) correctly advise us to limit our public

  comments regarding specific details of the case while litigation remains

  pending in court.  Nevertheless, Conservancy, as a

  non-profit charity serving the public good, seeks to be as transparent as

  possible.  If you have additional questions you'd like to see answered

  here, please <a href="mailto:info@sfconservancy.org">email

  &lt;info@sfconservancy.org&gt;</a>, but understand that we may often need

  to answer: <q>We cannot comment on this while litigation is pending</q>.</p>

  <dt>Who is the Plaintiff in the lawsuit?</dt>

  <dd>Christoph is one of most active developers of the Linux kernel. He has

   contributed 279,653 lines of code to the latest Linux 3.19 kernel, and

   thus ranks 20th among the 1,340 developers involved in that release.

   Christoph also ranks 4th among those who have reviewed third-party source

   code, and he has tirelessly corrected and commented on other developers'

   contributions.</dd>

  <dt id="court-documents">Are the court documents released?</dt>

  <dd>Not currently.  Court proceedings are not public by default in Germany

  (unlike in the USA).  Conservancy will continue to update this FAQ with

  information that Conservancy knows about the case.  We would all also

  welcome an agreement with VMware whereby both sides would agree to publish

  all Court documents. </dd>

  <dt>Who's funding this lawsuit?</dt>

  <dd>Conservancy has engaged in a grant agreement with Christoph Hellwig for

  the purposes of pursuing this specific legal action in Germany.

  Conservancy is funding this legal action specifically as part of

  Conservancy's program activity in

  its <a href="/linux-compliance/about.html">GPL Compliance

  Project for Linux Developers</a>.</dd>

  <dt>Is this the Great Test Case of Combined / Derivative Works?</dt>
