Porting FreeBSD Wi-Fi to NetBSD

Date: 2023-05-19
Time: 09:15–10:00
Room: DMS 1120
Level: Intermediate

Strong wifi support is a necessity for any modern operating system. NetBSD’s wireless networking stack has unfortunately grown dated relative to other BSD family operating systems. There is currently an effort in the NetBSD community to port the FreeBSD 802.11 stack to NetBSD. This will include many benefits, including support for 802.11n, easier future integration of 802.11ac/802.11ax, and new operating modes (such as WDS and Mesh) for wifi devices. The end goal is to have a shared code base between NetBSD and FreeBSD.

In this talk I will present the effort of porting FreeBSD’s wifi code. In addition to details about the development process, the lecture will also cover differences between NetBSD and FreeBSD’s wifi stacks, the advantages of the new stack, detailing new modes of operation, and work to be done.
