ovpn lands in VyOS: kernel-space OpenVPN, no config rewrites
We brought OpenVPN 2.7 and the in-kernel ovpn module to VyOS as open-source work, migrating existing configurations so that upgrades keep working.
One agent, 120,000 mesh devices, and a few patches to the Linux kernel
How we joined the team behind the cloud agent on 120,000+ mesh devices, from 32 MB Open-Mesh routers to Wi-Fi 6, and extended the Linux kernel where it fell short.
When the alert can’t be lost: a custom mesh protocol over LoRa
A European IoT provider needed battery-powered sensors at remote, off-grid sites to reach a single cellular gateway. We spent two years designing the mesh protocol that makes it work, from research to production.
Tracing random Wi-Fi unicast drops to a driver-level key handling bug
Clients connect, get an IP, and pass no traffic. No pattern, no logs, no way to reproduce it. How we found the cause in the ath9k driver and cut the complaints by 90%.
Designing and upstreaming ovpn, the OpenVPN kernel module
We designed ovpn, the Linux kernel module that runs the OpenVPN data plane in-kernel, and carried it through 16 months of review into mainline Linux 6.16.
Hundreds of commits, zero forks: building OpenVPN’s new features upstream
OpenVPN Inc. needed new protocol features without splitting from the open-source project. We’ve merged hundreds of commits into OpenVPN since 2016, from data channel offload to six headline features of OpenVPN 2.7.
From one developer’s workstation to traceable mesh firmware
A wireless mesh vendor couldn’t tell which code was running on its customers’ networks. We made its OpenWrt firmware builds traceable and reproducible, and cut its divergence from upstream.
