DHCPv6 rfc3315 support on Jolla

Some environments use DHCPv6 but there is no support on SailfishOS for this.

I would like to have support not just for autoconfiguration but also for dhcpv6 which would help in enterprise environments to get IPv6 connectivity.

I found out a interesting fact. It seems like Jolla is requesting a dhcpv6 address but does not assign it:

Jan 12 15:10:46 dhcp dhcpd: DHCPREQUEST for 192.168.0.11 (192.168.0.242) from 50:56:a8:01:24:94 via eth0

Ok I see Jolla is trying to connect to ipv6.jolla.com with it's link-local address which is not very successful ;).

20:04:31.620082 IP6 (hlim 64, next-header ICMPv6 (58) payload length: 88) fe80::5054:ff:feef:dfce > fe80::5256:a8ff:fe01:2494: [icmp6 sum ok] ICMP6, destination unreachable, length 88, beyond scope 2406:da00:ff00::36e1:47c7, source address fe80::5256:a8ff:fe01:2494

Ok, in the config for the wlan which uses IPv6 DHCP the connman config includes the settings for dhcpv6 but the ip address gets not assigned to my interface but routes are installed correctly.

IPv6.method=auto
IPv6.privacy=disabled
IPv6.DHCP.DUID=000100011a48bd675056a8012494
IPv6.DHCP.LastAddress=<prefix>:1::fffd

Sailor ( 2014-01-17 18:02:42 +0300 )edit

Now I found some errors in journcalctl:

Jan 18 16:03:33 jolla connmand[833]: Set IPv6 host route error (Invalid argument)
Jan 18 16:03:36 jolla connmand[833]: Set IPv6 host route error (Invalid argument)

I have found out that everytime I delete the entire network from the connman directory and readd it via GUI. DHCPv6 is working but if I connect the next time it's not working anymore.

Please update connman to minimum 1.17 because there (and in 1.16) are fixes for DHCPv6 and we have 1.15. https://connman.net/blogs/patrik/2013/connman-117

It looks like it's fixed in the latest update. For me it works now as expected.

DHCPv6 is started by ConnMan when the network supports it. So one needs radvd (or similar) in the network to send ND_RA_FLAG_MANAGED flag in its router advertisement message, that is the "AdvManagedFlag on" option in radvd configuration.

But it's simply not working ;). Only on first try because DAD is failing on second try.

Then connman update to 1.17 or later is needed, it has important dhcpv6 fixes as you have noticed.

DHCPv6 access on Jolla phone working without problem.

Trying IPv6 on Jolla tablet (ver. 2.1.2.3) proves it is only working with RA but not with DHCPv6

Anyone an idea why dhcpv6 client is faulty on Jolla tablet ?
