Every single software product is dealing with the question about what to do with “AI”-generated code, but the question is particularly difficult to answer for open source operating systems like Linux distributions and the various BSDs, which often consist of a wide variety of software packages from hundreds to thousands of different developers. On top of that, they also have to ask the “AI” question for every layer of their offering, from the base install, to the official repositories, to community-run ones…

Florian Obser (florian@) recently gave a BSD-NL talk entitled "Let's find out how to get predictable IPv6 addresses assigned to OpenBSD VMs".

Florian takes us on a guided tour of how inet6 autoconf actually works, with enlightening and entertaining peeks into selected piece of OpenBSD source.

At the end, we are asked to "now, draw the rest of the owl".

Wouldn’t you believe it, this site is running off my special home server: a Nintendo Wii with a 729 MHz PowerPC CPU and a whopping 64 MB usable RAM! It runs NetBSD 10.1 and serves this site exclusively over IPv6 – clients connecting through IPv4 are proxied via another server…

The NetBSD project is pleased to announce the third (and probably final) release candidate of the upcoming 11.0 release, please help testing!

Jails for NetBSD aims to bring lightweight, kernel-enforced isolation to NetBSD.

It is designed to fill the operational gap between simple chroot environments and full virtualization systems such as Xen.

What looks like a simple nginx config change turns out to involve SSL library compatibility, firewall rules for a new protocol, and a subtle multi-process routing problem that only surfaces under real traffic. This documents what it actually took to get HTTP/3 (QUIC) working on nginx 1.28 inside a FreeBSD 15.0 Bastille jail - serving the Mastodon instance at burningboard.net.

11.0 release expected before the end of february 2026

Kernel changes

• x86: PVH boot is now supported on non-XEN platforms (QEMU, Firecracker)
• various new drivers for temperature (and other environmental) sensors and fan control
• the heartbeat watchdog will detect locking errors that prevent softints from running or the timecounters from making progress on one of the CPUs
• On machines with no entropy source timing based entropy estimation allows unblocking of the entropy system (like it used to before NetBSD 10.0)
• lots of enhancements for Linux emulation
• new syscall: semtimedop(2)
• lots of enhancements to the riscv port
• various bug fixes

Userland changes

• libm got most (all?) missing long double and transcendental functions
• userland support for manipulating/querying (U)EFI variables has been added
• jemalloc has been updated to version 5.3
• various bug fixes to libpthread and making functions signal safe
• lots of miscelaneous bug fixes
• the in-tree X.org components are all (well, nearly - there are a few minor/unimportant exceptions) up-to-date

3rd party software updates included

• gcc for all architectures is now at version 12.5
• gdb for all architectures is now at version 15.1
• binutils for all architectures is now at version 2.42
• OpenSSL got updated to the latest long term support version available: 3.5.1
• OpenSSH is at version 10.0
• many others updated, including dhcpcd, openresolv, unbound, nsd, ...

#NetBSD 11.0 has been branched, and the stabilization process now begins. Pre-release snapshots will be available for users to try soon(tm).
