Re: Bug#768188: Jessie Installer hangs after processing DHCPv6 stateful addressing

So, I'm happy if you decide to revert this. At first glance, it reads like a limitation of udhcpc/dhcp6c only? Killing it sounds like a workaround (which perhaps creates other issues), and an ifdef linux also seems wrong in this context (and for Ubuntu). kill-all-dhcp could be told never to kill ISC dhclient, but that too is wrong, as this is also used to implement the 'Cancel' button in the netcfg dialogs. Maybe there is still a better solution? Or perhaps we could add something that kills *only* udhcpc/dhcp6c, could clearly annotate it as this is a workaround for bug #768188. Then it shouldn't affect Ubuntu, or derivatives/ports using ISC DHCP at all. And if many years pass before someone comes back to look at this, they should understand why it's there. Not killing the DHCP clients is the right thing to do. Leases really should be refreshed during d-i, everything else is madness. But that's not even what's happening with dhclient because it's being run in one-shot mode (-1) and will exit after it acquired a lease successfully. The revert I supposed would've been for jessie as the DHCPv6 hang is quite a nasty regression on Linux. But for the future we should really a) use one client on all the platforms and b) let it renew the lease properly. Kind regards Philipp Kern signature.asc Description: Digital signature

It will try only once to get a lease, initially. If successful it stays running - I assumed it continues to refresh the lease - and starting in the jessie version, will also give up the lease on SIGINT (that was #757711). I think reverting to what we had before reintroduces bugs, and would break downstream Ubuntu. I think a workaround should be more targetted at udhcpc/dhcp6c.

Hello, Thanks for the notice, Cyril Brulebois, le Wed 18 Feb 2015 22:29:23 +0100, a écrit : Philipp Kern pk...@debian.org (2015-02-18): So now I guess the question is if we revert the change that broke it: Don't kill_dhcp_client without reason (Closes: #757711, #757988) Do not kill_dhcp_client after setting the hostname and domain, otherwise Linux udhcpc will stop renewing its lease, and on other platforms dhclient will de-configure the network interface (Closes: #757711, #757988) (No idea about hurd; anyway, adding both porter lists to Cc.) dhclient gets killed indeed, but for some reason the interface is not deconfigured, so it's fine for the hurd port. We already have to ship our own version of netcfg already anyway because of #769189 which introduces a 1-minute sleep.
