[Touch-packages] [Bug 1633479] Re: dhclient does not wait for ipv6 dad (duplicate address detection)
Additional note for this bug: this has been "fixed" upstream by adding a --dad-wait-time parameter to dhclient. However, that param defaults to 0, and also requires an update to the dhclient-script.linux that isc- dhcp provides. Debian has its own modified dhclient-script.linux, slightly different than upstream, which is what we modified to fix this bug. The upstream bug is: https://bugs.isc.org/Public/Bug/Display.html?id=36169 I don't personally recommend using the upstream isc-dhcp "fix" for this; our change to the dhclient-script.linux maintained by debian/ubuntu is a better fix, at least for the SRU releases; and our change doesn't require tooling that uses dhclient to add a new --dad-wait-time parameter. ** Bug watch added: bugs.isc.org/Public/ #36169 https://bugs.isc.org/Public/Ticket/Display.html?id=36169 -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to isc-dhcp in Ubuntu. https://bugs.launchpad.net/bugs/1633479 Title: dhclient does not wait for ipv6 dad (duplicate address detection) Status in isc-dhcp package in Ubuntu: Fix Released Status in isc-dhcp source package in Precise: Fix Released Status in isc-dhcp source package in Trusty: Fix Released Status in isc-dhcp source package in Xenial: Fix Released Status in isc-dhcp source package in Yakkety: Fix Released Bug description: dhclient -6 does not wait for an interface go through duplicate address detection.

This does *not* appear to resolve a closely related problem where the link-local address has not yet been assigned. See LP: 1718568 In brief, the loop case " $out " in *\ dadfailed\ *) error "$dev: ipv6 dad failed." return 1;; *\ tentative\ *) :;; *) return 0;; esac exits with 'return 0' with the lack of a link-local address as " " ($out empty) matches the default pattern as would a valid, link-local address. One possible solution is to add "the missing case" that matches $out being empty that performs the "wait and try again" action. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to isc-dhcp in Ubuntu. https://bugs.launchpad.net/bugs/1633479 Title: dhclient does not wait for ipv6 dad (duplicate address detection) Status in isc-dhcp package in Ubuntu: Fix Released Status in isc-dhcp source package in Precise: Fix Released Status in isc-dhcp source package in Trusty: Fix Released Status in isc-dhcp source package in Xenial: Fix Released Status in isc-dhcp source package in Yakkety: Fix Released Bug description: dhclient -6 does not wait for an interface go through duplicate address detection.

[Touch-packages] [Bug 1633479] Re: dhclient does not wait for ipv6 dad (duplicate address detection)
I can also confirm trusty and precise as shown above. They behave differently, in that instead of exiting failure, dhclient actually tries again and ends up getting an address.

[Touch-packages] [Bug 1633479] Re: dhclient does not wait for ipv6 dad (duplicate address detection)
So I'm not convinced that doing this in dhclient is necessarily right. Unlike IPv4 where DHCP operates over a raw socket, in IPv6 mode, dhclient is just a regular network client and as such requires a source address to be set so it can contact the network (the link-local address in this case). As dhclient is supposed to only be triggered after a RA has been received and parsed, it should be the job of whatever handles the RA to wait until a viable link-local has been established before triggering dhclient. That being said, since we don't seem to have anything that handles that first configuration step properly, this workaround certainly won't hurt and will fix the current race condition. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to isc-dhcp in Ubuntu. https://bugs.launchpad.net/bugs/1633479 Title: dhclient does not wait for ipv6 dad (duplicate address detection) Status in isc-dhcp package in Ubuntu: Confirmed Bug description: dhclient -6 does not wait for an interface go through duplicate address detection.
