Copy Fail, Dirty Frag, and Fragnesia kernel vulnerabilities (May 19, 2026)

[IMG: Fragnesia logo]
The Linux kernel has recently been facing a series of discovered
privilege escalation vulnerabilities, starting with the
Copy Fail vulnerability and followed by subsequent
vulnerabilities in the same spirit
(Dirty Frag,
Fragnesia).
This development is part of a general trend where vulnerabilities are being found - and
disclosed - faster than before. We expect it to continue, at least for
the short-term.
The Gentoo Linux Kernel and Distribution Kernel teams are doing their best
to keep Gentoo kernels secure. This includes both packaging the latest
upstream releases as soon as possible, and backporting additional vulnerability fixes
or mitigations whenever they become available.
As example, while upstream kernel releases are still vulnerable to Fragnesia,
the respective Gentoo kernels feature fixes from day one. At the time of writing, all
supported Gentoo kernels feature the latest Fragnesia v5 patch. Please expect more updates.
We recommend exploring ways to automate upgrading your kernel.
Please note that only
sys-kernel/gentoo-kernel,
sys-kernel/gentoo-kernel-bin
and sys-kernel/gentoo-sources
packages are security-supported. The vanilla kernel packages are
vulnerable at the moment. Other kernel packages may carry fixes, but
they usually are slower to be updated. Additionally, we recommend
running the latest kernel version (~arch or latest stable LTS), as
upstream does not reliably backport security fixes to older versions.

The Gentoo Big Forum Upgrade (Apr 2, 2026)

[IMG: Gentoo Forums header]
It’s taken a lot of time, but we have finally made the big step to upgrade our Gentoo Forums
to phpBB3. You will notice a few differences between phpBB2 and today:
It’s definitely not Discourse.
Everyone must change their password at first login, just to freshen them up.
Reports are more private-like now, but we may get the old public reporting topic back later.
Discussion and feedback are welcome on the ‘The Gentoo Big Forum Upgrade’ discussion thread.

Gentoo GNU/Hurd (Apr 1, 2026)

[IMG: Larry with Hurd logo]
We are proud to announce a new port of Gentoo to GNU Hurd!
Our crack team has been working hard to port Gentoo to the Hurd and can now share that
they’ve succeeded, though it remains still in a heavily experimental stage.
You can try Gentoo GNU/Hurd using a pre-prepared disk image. The easiest way to do this is with QEMU:
$ wget https://distfiles.gentoo.org/experimental/x86/hurd/hurd-i686-preview.qcow2.sig
$ wget https://distfiles.gentoo.org/experimental/x86/hurd/hurd-i686-preview.qcow2
$ gpg --verify hurd-i686-preview.qcow2.sig hurd-i686-preview.qcow2
$ qemu-system-i386 -drive file=hurd-i686-preview.qcow2,format=qcow2 -m 2G -net user,hostfwd=tcp:127.0.0.1:2222-:2222 -net nic,model=ne2k_pci --enable-kvm -M q35
To log in, input login root, then use gnuhurdrox as the password. Upon logging in,
you can run ./setup-net.sh and /etc/init.d/sshd restart to get SSH. Connect
via ssh -p 2222 root@127.0.0.1 on your host.

Supercharging our forums with AI (Apr 1, 2026)

[IMG: Gentoo Forums header]
This turned out to be an April Fool’s post. For the real upgrade announcement
see here.
The Gentoo Forums are being upgraded for us to be able to leverage the latest in
modern bleeding edge technologies. As many of you are no doubt aware, phpBB has
been a challenging maintenance burden and despite years of effort, migrating to
phpBB 3 has been eternally stuck. It is time to acknowledge this and find
another solution. Fortunately, there is precedent from other FOSS communities
that faced a similar problem.
tl;dr, we have chosen Discourse as the new forum software.
It seems doubtful that we will be able to import any of the old posts, and will
likely start completely clean. However, we have been working on implementing AI
features utilised via the Discourse API, which will scrape the internet for our
old forums content (and more!), and post them for us in our new home.
Due to this, viewing new posts will include old posts as well for the next few
years or so, depending on how much of the old forums are backed up via the
Internet Archive and similar archival sites. We have reasonably high hopes
that many threads will appear exactly as they used to
(after all, AI can only regurgitate what already existed…).
We understand that this move will be controversial, and have been working on some
light themeing skins that will make it look a bit more like the classic phpbb2 of
old, which hopefully should help alleviate most concern.

In Memory of Hans de Graaff (Feb 26, 2026)
We share the tragic news that Hans de Graaff (graaff), a longtime Gentoo
developer, has passed away.
Hans was a dedicated member of the Gentoo community for over 20 years, near
single-handedly maintaining Ruby ecosystem support. He also brought his
careful attention to important security work in Gentoo in the last few years.
Kind, patient, and dedicated - we mourn the loss of a wonderful colleague.
Our deepest condolences to his family. Donations in his memory can be made
for CAR T cell therapy at the LUMC Foundation.
Please join us in remembering Hans on the Gentoo forums.
Details on the funeral (including an online stream) to be held on
2026-03-02 can be obtained by contacting Elvike Reitsma (elvike AT winkwaves.com).

Gentoo on Codeberg (Feb 16, 2026)

[IMG: Codeberg logo]
Gentoo now has a presence on Codeberg, and contributions can be submitted for the Gentoo
repository mirror at https://codeberg.org/gentoo/gentoo as an alternative to GitHub.
Eventually also other git repositories will become available under the Codeberg Gentoo organization.
This is part of the gradual mirror migration away from GitHub, as already mentioned in the 2025 end-of-year review.
Codeberg is a site based on Forgejo, maintained by a dedicated
non-profit organization,
and located in Berlin, Germany. Thanks to everyone who has helped make this move possible!

Urgent - OSU Open Source Lab needs your help (Apr 30, 2025)

[IMG: OSL logo]
Oregon State University’s Open Source Lab (OSL) has been a major supporter
of Gentoo Linux and many other software projects for years.
It is currently hosting several of our infrastructure servers as well as development machines for exotic
architectures, and is critical for Gentoo operation.
Due to drops in sponsor contributions, OSL has been operating at loss for a while, with the OSU College
of Engineering picking up the rest of the bill. Now, university funding has been cut, this is not
possible anymore, and unless US$ 250.000 can be provided within the next two weeks OSL will have to
shut down. The details can be found in a blog post of
Lance Albertson, the director of OSL.
Please, if you value and use Gentoo Linux or any of the other
projects that OSL has been supporting, and if you are in a position to make funds available, if
this is true for the company you work for, etc … contact the address
in the blog post. Obviously, long-term corporate sponsorships
would here serve best - for what it’s worth, OSL developers have ended up at almost every big US
tech corporation by now. Right now probably everything helps though.

DTrace 2.0 for Gentoo (Oct 23, 2024)

[IMG: The DTrace Ponycorn]
The real, mythical DTrace comes to Gentoo! Need to dynamically trace
your kernel or userspace programs, with rainbows, ponies, and unicorns - and all entirely safely and in production?!
Gentoo is now ready for that! Just emerge
dev-debug/dtrace
and you’re all set. All required kernel options are already enabled in the newest stable Gentoo distribution kernel; if you
are compiling manually, the DTrace ebuild will inform you about required configuration changes.
Internally, DTrace 2.0 for Linux builds on the BPF
engine of the Linux kernel, so don’t be surprised if the awesome cross-compilation features of Gentoo are
used to install a gcc that outputs BPF code (which, btw, also comes in very handy for
sys-apps/systemd).
Documentation? Sure, there’s lots of it. You can start with our DTrace
wiki page, the DTrace for Linux page on GitHub,
or the original documentation for Illumos.
Enjoy!

Arm Ltd. provides fast Ampere Altra Max server for Gentoo (Oct 7, 2024)

[IMG: Arm Ltd. logo]
We’re very happy to announce that Arm Ltd. and specifically its
Works on Arm team
has sent us a fast Ampere Altra Max
server to support Gentoo development. With 96 Armv8.2+ 64bit cores, 256 GByte of
RAM, and 4 TByte NVMe storage, it is now hosted together with some of our other hardware at
OSU Open Source Lab. The machine will be a clear boost to our
future arm64 (aarch64) and arm (32bit) support, via installation
stage builds and binary
packages, architecture testing of Gentoo packages, as well as our close work with upstream
projects such as GCC and glibc. Thank you!

Much improved MIPS and Alpha support in Gentoo Linux (Sep 11, 2024)

[IMG: MIPS and Alpha logos]
Over the last years, MIPS and
Alpha support in Gentoo has been slowing down,
mostly due to a lack of volunteers keeping these architectures alive. Not anymore however! We’re happy
to announce that thanks to renewed volunteer interest both arches have returned to the forefront of
Gentoo Linux development, with a consistent dependency tree checked and enforced by our continuous integration system.
Up-to-date stage builds and the accompanying binary packages are available for both, in the case of
MIPS for all three ABI variants
o32, n32, and n64 and for both big and little endian, and in the case of
Alpha also with a
bootable installation CD.

Exciting news for stable Gentoo users: It’s time for the upgrade to the new “megaversion”
of the KDE community desktop environment, KDE Plasma
6! Together with KDE Gear 24.05.2, where
now most of the applications have been ported, and
KDE Frameworks 6.5.0, the underlying
library architecture, KDE Plasma 6.1.4 will be stabilized over the next days.
The base libraries of Qt 6 are already available.
More technical information on the upgrade, which should be fairly seamless, as well as
architecture-specific notes can be found in a
repository
news item. Enjoy!

Gentoo Linux drops IA-64 (Itanium) support (Aug 14, 2024)

[IMG: Intel Itanium logo]
Following the removal of IA-64 (Itanium) support in the Linux
kernel and glibc,
and subsequent discussions
on our mailing list, as well as a vote
by the Gentoo Council, Gentoo will discontinue all ia64 profiles and keywords. The primary reason for this decision is the
inability of the Gentoo IA-64 team to support this architecture without kernel support, glibc support, and a functional development
box (or even a well-established emulator). In addition, there have been only very few users interested in this type of hardware.
As also announced in a news item, in one month,
i.e. in the first half of September 2024, all ia64 profiles will be removed, all ia64 keywords will be dropped from all packages, and all
IA-64 related Gentoo bugs will be closed.
