Yeah I'm also not entirely sure. But I'm assuming that the maintainers insight into all the interactions is better than mine and therefore tend to follow.
About the "why the difference DHCPv6 vs SLAAC" I think that is fine because the code now allows to behave different (reasonable). And the defaults as configured by NM or anything else could configure lifetimes for DHCPv6+SLAAC then no behavior change would happen. Thereby (with a lot of un-sureness left) I'd intend to drop this change now (somewhat early/mid in 21.10) to identify any worse fallout better now than later. I've closed my Debian bug that I spawned back in the day. I will prepare an upload of dnsmasq, then we will see which tests or behavior break on it nowadays. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to dnsmasq in Ubuntu. https://bugs.launchpad.net/bugs/1894619 Title: [2.82 regression] router announcements have 'forever' lifetime by default Status in dnsmasq package in Ubuntu: Fix Released Status in dnsmasq package in Debian: New Bug description: The default lifetime was changed to 1 day in 2.82 in the change corresponding to this changelog entry: Change default lease time for DHCPv6 to one day. Fine, but the same commit also did this: Alter calculation of preferred and valid times in router advertisements, so that these do not have a floor applied of the lease time in the dhcp-range if this is not explicitly specified and is merely the default. And that change is buggy and causes advertisements to have infinite lifetime, when you are using the default.
