Sorry, that should be:
server Ubuntu 18.04
client arch linux
but the resulting vpn is ipv6 only and works well.

Hi,

I have applied these 5 patches to master on ubuntu 18.04LTS
The resulting binary gave server+client ipv6 *only* tunnel
over ipv4 network.  100% success

Using only: --server-ipv6 12fc:1918::10:186:0:0/112

I am sure buildbot runs more extensive tests than my single test
but I would be happy to ACK this if i could work out how to.

Thanks

This patchset allows clients and servers to work with a
tunnel configured with IPv6 only.

Patches 2 and 3 are mere cosmetic changes and could be merged
regardless of the rest (note that 3 depends on 2).

With this change a server can be configured by using only the
'--server-ipv6' directive.
This will result in clients receiving only 'ifconfig-ipv6'
setting in their push-reply (and no IPv4 at all).

Given that different components required changes in order
to achieve this goal, the patchset has been organized as follows:
- patch 1 alters the tun logic (client & server side)
- patch 4 alters the ifconfig-pool logic (server side)
- patch 5 alters the server config logic (server side)


Although I have tested the patchset with different configurations
and with our buildbots, such change would definitely benefit
from a broader testing campaign (even before being merged).


Cheers,

Trac: #208

Antonio Quartulli (5):
   tun: ensure interface can be configured with IPv6 only
   pool: restyle ipv4/ipv6 members to improve readability
   pool: convert pool 'type' to enum
   pool: allow to configure an IPv6-only ifconfig-pool
   make server capable of starting with an IPv6-only tunnel
