Merge pull request #1700 from wido/ipv6-basic-networking
CLOUDSTACK-9359: IPv6 for Basic NetworkingThis PR is a proposal for adding very
basic IPv6 to Basic Networking. The main goal of this PR is that the API
returns a valid IPv6 address over which the Instance is reachable.
The GUI will show the IPv6 address after deployment of the Instance.
If the table VLAN has a proper IPv6 CIDR configured the
DirectPodBasedNetworkGuru will calculate the IPv6 Address the Instance will
obtain using EUI-64 and SLAAC: https://tools.ietf.org/search/rfc4862
In this case the _vlan_ table contained:
<pre>mysql> select * from vlan \G
*************************** 1. row ***************************
id: 1
uuid: 90e0716c-5261-4992-bb9d-0afd3006f476
vlan_id: vlan://untagged
vlan_gateway: 172.16.0.1
vlan_netmask: 255.255.255.0
description: 172.16.0.10-172.16.0.250
vlan_type: DirectAttached
data_center_id: 1
network_id: 204
physical_network_id: 200
ip6_gateway: 2001:980:7936:112::1
ip6_cidr: 2001:980:7936:112::/64
ip6_range: NULL
removed: NULL
created: 2016-07-19 20:39:41
1 row in set (0.00 sec)
mysql></pre>
It will then log:
<pre>2016-10-04 11:42:44,998 DEBUG [c.c.n.g.DirectPodBasedNetworkGuru]

The template has to be configured accordingly:
- No IPv6 Privacy Extensions
- Use SLAAC
- Follow RFC4862
This is also described in:
https://cwiki.apache.org/confluence/display/CLOUDSTACK/IPv6+in+Basic+Networking
The next steps after this will be:
- Security Grouping to prevent IPv6 Address Spoofing
- Security Grouping to filter ICMP, UDP and TCP traffic
