Upcoming EuroBSDCon OpenBSD talk OpenBSD vs. IPv6 by Florian Obser
** .ical](events.eurobsdcon.org/2024/talk/AV78U9.ics)09-21, 17:45–18:30 (Europe/Dublin), Foyer B **
We will give an overview of past, present and future work on IPv6 in OpenBSD.
We will show how we replaced KAME stack code in both the kernel as well as userland with modern, privilege separated daemons for stateless address auto configuration. slaacd(8) runs on the host to solicit router advertisements and configures addresses and routes. rad(8) runs on the router to send router advertisements. A newly written daemon for DHCPv6, dhcp6leased(8), requests prefixes from an upstream ISP which then can be used by rad(8) for router advertisements.
Next we will show the new IPv6 source address selection in the kernel, including support for the infamous Rule 5.5 of RFC 6724.
In ongoing and future work we will touch on client-side address translation using pf(4)'s af-to feature to support the 464XLAT transition mechanism for v6-mostly networks.
