/sbin/dhclient-script in precise's isc-dhcp-client 4.1.ESV-R4-0ubuntu5.8 contains the following snippet:
BOUND6|RENEW6|REBIND6)
if [ -z "${new_ip6_address}" ] || [ -z "${new_ip6_prefixlen}" ]; then
exit_with_hooks 2
fi
# set leased IP
ip -6 addr add ${new_ip6_address}/${new_ip6_prefixlen} \
dev ${interface} scope global
This assumes that the result of the DHCPv6 transaction is an address with a prefix, which is the case for stateful DHCPv6. For stateless DHCPv6, however, we only get additional information that's not directly address-related. This is fixed in saucy and reads like this:
BOUND6|RENEW6|REBIND6)
if [ "${new_ip6_address}" ] && [ "${new_ip6_prefixlen}" ]; then
# set leased IP
ip -6 addr add ${new_ip6_address}/${new_ip6_prefixlen} \
dev ${interface} scope global
fi
It looks like the only change from the diff to the current saucy version we need for it to work correctly. |
[Impact]
isc-dhcp-client in precise does not do stateless DHCPv6 correctly if it's enabled as "dhcp 1" within "iface <IFACE> inet6 auto" within /etc/network/interfaces. The dhclient-script responsible for updating /etc/resolv.conf exists if it doesn't find an IPv6 address in its environment, which is only true for stateful DHCPv6.
[Test Case]
* You should have IPv6 on your network segment, make a note of the subnet.
* Have a stateless DHCPv6 server listen on the network segment:
** Minimal dhcpd6.conf:
authoritative;
option dhcp6.name-servers 2001:4860:4860::8888, 2001:4860:4860::8844;
option dhcp6.domain-search "ubuntu.com";
subnet6 fd7a:4ac2:1751:0::/64 {};
** Adjust the subnet information to the one you're actually using or the DHCP server will refuse to start.
** Install isc-dhcp-server on a host on the same network segment.
** Start up the server there using: /usr/sbin/dhcpd -cf dhcpd.conf -6 -lf /tmp/leases.test
* Have network configuration be managed by ifupdown, not network-manager:
* Add the following configuration to /etc/network/interfaces:
iface eth0 inet6 auto
dhcp 1
* ifdown eth0
* ifup eth0
* Check if /etc/resolv.conf contains:
search ubuntu.com
nameserver 2001:4860:4860::8888
nameserver 2001:4860:4860::8844
[Regression Potential]
The suggested change is already present since quantal. The change itself is self-contained
[Additional Info]

BOUND6|RENEW6|REBIND6)
