When ovn/dns_servers consist of IPv6 dns nameservers, it was getting added to IPv4 dhcp options also, and due to this an invalid nameserver(last 4 octets of an IPv6 address) is set in the instances. This patch filters IPv4/IPv6 dns nameservers and set dhcpv4/dhcpv6 options accordingly. Also when dns_nameservers are not set for IPv6 subnets, get those from ovn/dns_servers config or system nameservers just like it's done with the IPv4 subnets. Updated get_system_dns_resolvers to pick both IPv4/IPv6 valid ips, this also requires bump of oslo.utils minimum version to 4.8.0 to use strict option for IPv4[1]. Additionally fix some unit tests which were setting IPv4 dns nameservers on the IPv6 subnets, this is not allowed with api.

fixes:
|
|
- |
|
|
For IPv4 subnets when dns_nameservers is not set in the subnet,
|
|
servers defined in 'ovn/dns_servers' config option or system's
|
|
resolv.conf are used, but for IPv6 subnets these are
|
|
not used. The same will now be used for IPv6 subnets too.
|
|
Additionally dns servers added in 'ovn/dns_servers' config
|
|
option or system's resolv.conf will be filtered as per
|
|
the subnet's IP version. For more info see the bug report
