liuyulong | Hi guys, I may ask a question about IPv6. Information and advise are all welcomed. | 15:22 |
*** tssurya has quit IRC | 15:22 | |
*** yamamoto has joined #openstack-neutron | 15:22 | |
liuyulong | For DHCPv6-stateful, aka "--ipv6-ra-mode DHCPv6-stateful --ipv6-address-mode DHCPv6-stateful", the subnet range must be /64? or not? | 15:23 |
liuyulong | For DHCPv6, there is no "subnet-mask" option, so how to specify a certain range for one DHCPv6 request? | 15:24 |
liuyulong | And I noticed that the dnsmasq option "--dhcp-range=set:tag1,xxxx:xxxx:xxxx:ffff:8000:0:28:0,static,110,infinite" does now work! | 15:26 |
liuyulong | cmd.append('--dhcp-range=%s%s,%s,%s,%d,%s' % ('set:', self._TAG_PREFIX % i, cidr.network, mode, cidr.prefixlen, lease)) This is the original code. | 15:27 |
liuyulong | https://github.com/openstack/neutron/blob/master/neutron/agent/linux/dhcp.py#L399-L402 | 15:28 |
*** yamamoto has quit IRC | 15:29 | |
liuyulong | In RFC 3315: https://tools.ietf.org/pdf/rfc3315.pdf, I did not see a mandatory requirement for such range subnet range. But seems 'dhclient' and 'dnsmasq' can not work in such scenario. Or maybe I miss some important thing? | 15:30 |
openstackgerrit | Lucas Alvares Gomes proposed openstack/networking-ovn master: WIP: Virtual port support https://review.opendev.org/676223 | 15:35 |
haleyb | liuyulong: i don't think there's any requirement about using /64 for dhcpv6 stateful, it's just the "normal" length used on a network (rfc 8415 only mentions it in the IA_PD sections) | 15:37 |
haleyb | stateful is the hardest to get working properly IMO, slaac or stateless is more typical | 15:38 |
liuyulong | haleyb, let me revisit the rfc 8415 again... | 15:40 |
liuyulong | My thoughts is not to introduce another new external process for neutron... Prefix delegation needs dibbler-server according to this doc: https://docs.openstack.org/neutron/stein/admin/config-ipv6.html | 15:43 |
haleyb | liuyulong: prefix delegation needs some kind of server, can live in the upstream router (eg think that's a cisco config thing), but neutron only requires dibbler-client | 15:46 |
liuyulong | Some detail about my test is: create one subnet pool with "--pool-prefix 2001:db8:2222:6977::/64" and "--default-prefix-length 110". User creates IPv6 subnet from this pool will have a xxxx:xxxx::/110 range, the mode is "--ipv6-ra-mode DHCPv6-stateful --ipv6-address-mode DHCPv6-stateful". | 15:47 |
liuyulong | But everytime, the VM will get a IPv6 address with /64 prefix. | 15:47 |
liuyulong | Not /110 | 15:48 |
haleyb | how is VM configuring it? based on the dhcpv6 response? | 15:48 |
liuyulong | This is the centos7.5 default dhclient daemon "/sbin/dhclient -6 -1 -lf /var/lib/dhclient/dhclient6--eth0.lease -pf /var/run/dhclient6-eth0.pid eth0 -H yulong-test-ipv6-vm-1" | 15:49 |
liuyulong | Yes, DHCPv6 | 15:49 |
liuyulong | Option "-R subnet-mask,...,..." does not work for dhclient of IPv6. | 15:50 |

haleyb | liuyulong: so i guess nothing is setting a prefix length? sorry, stateful is the one i know least | 15:53 |
liuyulong | haleyb, yes, no PD server in such test. | 15:55 |
frickler | dhcpv6 only assigns an address as /128, the prefix comes via RA. not sure though whether an RA can contain a prefixlength or it always assumes /64 | 15:55 |
liuyulong | frickler, yes, I can see VM send RA out | 15:56 |
liuyulong | if prefix only comes from RA, then a PD server is needed anyway? | 15:57 |

*** vesper11 has quit IRC | 15:58 | |
*** ociuhandu has quit IRC | 15:58 | |
haleyb | liuyulong: the prefix information option would appear in the RA from the neutron router, and it has a length field in it | 15:58 |
haleyb | but i don't know if it's included when it's not slaac/stateless, tcpdump would know :) | 15:59 |
liuyulong | Maybe we should update the IPv6 doc for such scenario, or all those permutation and combination of scenarios of "slaac" and "dhcpv6-stateless". | 15:59 |
*** vesper11 has joined #openstack-neutron | 16:00 | |
liuyulong | haleyb, I'm tcpdumping it now. | 16:00 |
*** jlibosva has quit IRC | 16:01 | |
*** markvoelker has quit IRC | 16:02 | |
haleyb | liuyulong: in a typical deployment, i would assume there is a PD server on the external network, and so when you configure your neutron router/network for PD, it gets a prefix it will then assign to the private network (i hope that part is clear) | 16:02 |
haleyb | in that case the prefix is completely routable in the datacenter | 16:03 |

liuyulong | this is radvd config for one router. | 16:07 |
frickler | liuyulong: please use paste.openstack.org for multiline pastes | 16:07 |
frickler | but yes, I just tested the same, if the client handles that correctly, all should be fine | 16:08 |
liuyulong | but I did not see perfix in Neighbor Advertisement, something wrong? | 16:08 |
amotoki | PD and a subnet size are not tightly coupled. | 16:09 |
*** absubram has joined #openstack-neutron | 16:09 | |
amotoki | from my limited experience on ipv6, many impls assume /64 subnet size. | 16:09 |
*** lucasagomes has quit IRC | 16:10 | |
amotoki | RA seems to carry subnet size per RFC though. | 16:10 |
frickler | liuyulong: how to you check that? when I do a tcpdump, it shows the /96 I'm testing with correctly | 16:11 |

liuyulong | amotoki, yes, I also searched some info with such content, /64 is default. | 16:17 |
*** dsneddon has quit IRC | 16:17 | |
frickler | liuyulong: works fine for me, can you show a paste of it? I see http://paste.openstack.org/show/756531/, same on the tap if | 16:18 |
liuyulong | This is an output from wireshark: http://paste.openstack.org/show/756532/ | 16:20 |
frickler | liuyulong: those are neighbor advertisements, you need to look at a router advertisement | 16:21 |
frickler | also might need a more verbose output to see the details about the prefix | 16:22 |
liuyulong | None of those packets have a prefix info. | 16:22 |
liuyulong | OK, let me tcpdump in qrouter-ns also. | 16:23 |
haleyb | frickler: that was from dnsmasq, right? your paste did have the PIO with a /96 | 16:24 |
frickler | haleyb: radvd is what generates the RAs | 16:25 |
haleyb | doh, right, i can't remember our own code | 16:25 |

openstackgerrit | Akihiro Motoki proposed openstack/networking-bagpipe master: Upgrade pylint to a version that works with python3 https://review.opendev.org/629174 | 16:27 |
*** dsneddon has joined #openstack-neutron | 16:27 | |
liuyulong | OK, I can tcpdump the prefix info in router namespace. So maybe some security group rules drop the dl_dst "33:33:00:00:00:01" packets.... | 16:28 |
liuyulong | On compute host VM tap-device, I can not tcpdump any of such packets. | 16:29 |
amotoki | Don't we have a provider rule to accept RA packets? RA packets should not be dropped :( | 16:30 |
liuyulong | ICMPv6 rule for ingress and egress are all added. | 16:31 |

liuyulong | ovs | 16:35 |
liuyulong | http://paste.openstack.org/show/756534/ this is the output in qrouter-ns after a "dhclient -6 -r" and "dhclient -6 ..." | 16:36 |
