commit a56a35572d7b7d4b534825fe7b4f681028121a74 Author: Eugene Nikanorov <[email protected]> Date: Mon Aug 25 00:59:02 2014 +0400 Raise exception if ipv6 prefix is inappropriate for address mode Address prefix to use with slaac and stateless ipv6 address modes should be equal to 64 in order to work properly. The patch adds corresponding validation and fixes unit tests accordingly. Change-Id: I6c344b21a69f85f2885a72377171f70309b26775 Closes-Bug: #1357084 (cherry picked from commit 0d8911115e1b722da2f1e92f444e53b22223ee32) ** Changed in: neutron Status: Fix Committed => Fix Released -- You received this bug notification because you are a member of Yahoo! Engineering Team, which is subscribed to neutron. https://bugs.launchpad.net/bugs/1357084 Title: IPv6 slaac is broken when subnet is less than /64 Status in OpenStack Neutron (virtual network service): Fix Released Bug description: SLAAC and DHCPv6 stateless work only with subnets with mask /64 and more (/63, /62) because EUI-64 calculated IP takes 8 octets. If subnet mask is /65, /66, .., /128 SLAAC/DHCP stateless should be disabled. API call for creating subnet with SLAAC/DHCP stateless and mask more than /64 should fail. Example: let's create net and subnet with mask /96: $ neutron net-create 14 $ neutron subnet-create 14 --ipv6-ra-mode=slaac --ipv6-address-mode=slaac --ip-version=6 2003::/96 Created a new subnet: ... | allocation_pools | {"start": "2003::2", "end": "2003::ffff:fffe"} | | cidr | 2003::/96 | .... | | gateway_ip | 2003::1 | ... | ipv6_address_mode | slaac | | ipv6_ra_mode | slaac | ... Let's create port in this network: $ neutron port-create 14 --mac-address=11:22:33:44:55:66 Created a new port: ... | fixed_ips | {"subnet_id": "1bfe4522-3b71-4e74-bb80-44c853ff868d", "ip_address": "2003::1322:33ff:fe44:5566"} | ... | mac_address | 11:22:33:44:55:66 | ... As you see port gets IP 2003::1322:33ff:fe44:5566 which is not from original network 2003::/96.
