VyOS Project May 2025 Update

Hello, Community!

Quite a lot of things have happened since the last update we posted in April. In particular, we added the last bit of functionality that we considered a hard requirement for the VPP-based accelerated dataplane: support for VPP firewall. This marks the point when we consider the minimal viable product complete and we plan to ship it in a VyOS Stream release later this year, likely in Q3 — although you don't have to wait for it to play around with it, since it's already in the rolling release.

We are also making a very good progress towards replacing the legacy config backend — that work is still in the development phase and has no visible effects, and will take a while longer to complete, but it's underway.

When it comes to bugs, there are more than twenty recent fixes, including a fix for the nasty bug that led to routing protocol configuration loss if a protocol daemon crashed. Another important fix contributed by a community member makes VMware VMs suspend and resume correctly. Last but not least, the login prompt is no longer displayed in a bold font — that one took more time to track down than anyone hoped, and turned out to be caused by a truncated Systemd service name (ANSI control codes do not reset themselves on word boundaries, you know...).

There are multiple improvements in the base system as well. There's a new set ystem option reboot-on-upgrade-failure command that makes the system automatically reboot into the previous image if the configuration fails to load after upgrade. We hope it will help multiple people avoid unplanned trips to remove places — of course there should be out-of-band management everywhere for this case, but we all know that the real world is not perfect.

Other recently added features include support for IPv6 address in the datasets for firewall remote groups, BPDU guard and root guard supports for bridges, a new option to limit BRAS services (IPoE, PPPoE, and friends) to a specific number of CPU cores to avoid system overload, and more — read on for details!

VyOS 1.4.2 release

daniil@sentrium.io (Daniil Baturin) — Thu, 03 Apr 2025 16:28:13 GMT

Hello, Community! VyOS 1.4.2 release images and the corresponding source tarball are now available for download to customers and holders of contributor subscriptions.

This release includes a fix for a security issue that made console server users vulnerable to MitM attacks, over forty bug fixes, a few improvements in BRAS functionality, performance optimizations that can improve BGP convergence time by as much as 5-10 minutes in some scenarios, and other improvements. Additionally, FastNetMon is now deprecated and is scheduled to be removed in the future 1.5 release, and we are also finally phasing out legacy GnuPG signatures in favor of minisign. Read on for details!

VyOS Project December 2024 Update

daniil@sentrium.io (Daniil Baturin) — Mon, 30 Dec 2024 15:56:27 GMT

Hello, Community!

The December update is here! The biggest highlight of this month is the 1.4.1 release but there was lots of work in the rolling release as well, both from the maintainers team and from our contributor community. One of the biggest news in the rolling release is that we are ready to update FRR — our routing protocol stack — to the latest 10.2 release. That will allow us to get rid of the legacy OpenNHRP daemon that we use for DMVPN and use FRR's built-in NHRP implementation, among other things.

Apart from that, there are many more bug fixes and improvements made in November and December, especially in QoS, IPoE server, and other areas — read on for details!

Hello, Community!

Summer is over now, and many people are returning to their routines. Check out what we've done in the last month of the summer: that includes a few small config syntax changes, multiple improvements in OpenVPN, an API endpoint for importing PKI objects, and a whole bunch of bug fixes!
