Thanks for filing this bug Iain. I am tagging it as server-next and it should be worked on by our team soon. As a source of information for the person who will work on it here is the patch submitted by Iain:
http://lists.thekelleys.org.uk/pipermail/dnsmasq- discuss/2020q3/014345.html And in the reply of this message a flaw seems to be found and a new patch was proposed (asked for review): http://lists.thekelleys.org.uk/pipermail/dnsmasq- discuss/2020q3/014346.html ** Tags added: server-next -- 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: Triaged 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.
