SFC: GPL Violations Related to Combining ZFS and Linux

[Announcements] Posted Feb 25, 2016 16:56 UTC (Thu) by jake

The Software Freedom Conservancy (SFC) has put out an analysis of the recently announced plans of Canonical to provide and support ZFS as part of Ubuntu 16.04. There are some license-compatibility questions within the community, but Canonical believes that it is within its rights to distribute the CDDLv1-licensed zfs.ko kernel module with the GPLv2-licensed kernel. SFC, however, disagrees: "We are sympathetic to Canonical's frustration in this desire to easily support more features for their users. However, as set out below, we have concluded that their distribution of zfs.ko violates the GPL. We have written this statement to answer, from the point of view of many key Linux copyright holders, the community questions that we've seen on this matter. Specifically, we provide our detailed analysis of the incompatibility between CDDLv1 and GPLv2 — and its potential impact on the trajectory of free software development — below. However, our conclusion is simple: Conservancy and the Linux copyright holders in the GPL Compliance Project for Linux Developers believe that distribution of ZFS binaries is a GPL violation and infringes Linux's copyright. We are also concerned that it may infringe Oracle's copyrights in ZFS. As such, we again ask Oracle to respect community norms against license proliferation and simply relicense its copyrights in ZFS under a GPLv2-compatible license."
