Written as part of the FreeBSD Project’s 4th Quarter 2025 Status Report, check out the highlights of what we did to help FreeBSD last quarter:

The FreeBSD Foundation is a 501(c)(3) non-profit dedicated to advancing FreeBSD through both technical and non-technical support. Funded entirely by donations, the Foundation supports software development, infrastructure, security, and collaboration efforts; organizes events and developer summits; provides educational resources; and represents the FreeBSD Project in legal matters.

Here are some of the ways we supported FreeBSD in the fourth quarter of 2025.

OS Improvements

Throughout the quarter, there were 346 src, 72 ports, and 58 doc commits sponsored by the FreeBSD Foundation.

Refer to the following report entries describing much of that committed development work:

Other highlights include:

  • A new kqueue1(KQUEUE_CPONFORK) facility to copy kqueue into the child on fork

  • exterror(9) infrastructure for asynchronous io and geom

  • libuvmem(3) usermode port of vmem(9)

  • Fixes for anonymous memory corruption

  • Fine-grained support for groups and manual page MFCed to 14

  • Bug fixes

    • A 32-bit mdo(1) on a 64-bit FreeBSD would always fail with EINVAL

    • Panic when using mdo(1) and resource accounting is enabled (kern.racct.enable set to 1)

  • MAC system reviews

  • Kick-off of S4 (hibernate) support

  • Background work on VFS (in particular supporting unionfs changes)

The Foundation also continued to support two major initiatives: the Laptop Support and Usability project (in collaboration with Quantum Leap Research) and an infrastructure modernization project commissioned by the Sovereign Tech Agency. For background on both efforts, see the 2025Q1 quarterly status report.

We began preparing for FreeBSD’s 22nd consecutive participation in Google Summer of Code (GSoC). Those interested in contributing project ideas or mentoring are encouraged to contact soc-admins@FreeBSD.org.

Continuous Integration and Workflow Improvement

As part of our continued support of the FreeBSD Project, the Foundation supports a full-time staff member dedicated to improving the Project’s continuous integration system and test infrastructure.

Advocacy

In the fourth quarter of 2025, our advocacy work focused on expanding our educational video content, reaching more viewers than ever, bringing the community together for a productive Vendor Summit, and reflecting on the work that is helping sustain and grow interest in FreeBSD. Here are just a few of the ways the Foundation advocated for FreeBSD in Q4 2025:

The Foundation supports a full-time staff member dedicated to improving the Project’s continuous integration system and test infrastructure.

Legal/FreeBSD IP

The Foundation owns the FreeBSD trademarks, and it is our responsibility to protect them. We also provide legal support for the core team to investigate questions that arise.
