Description

Hi

My ISPs DHCP6 server uses the Unicast Option (http://tools.ietf.org/html/rfc3315#section-22.12) which seemingly dhcp6c can't handle:

It is leading to the following lines in the log

dhcp6c[81281]: dhcp6_get_options: unknown or unexpected DHCP6 option server unicast, len 16
dhcp6c[81281]: update_ia: status code for NA-0: success
...
dhcp6c[81281]: dhcp6_get_options: unknown or unexpected DHCP6 option server unicast, len 16
dhcp6c[81281]: update_ia: status code for PD-0: success

which then leads to the [restart of / issues with] multiple services (at least openvpn, radvd, dnsmasq, ntp) (example from log: openvpn25405: SIGTERM[hard,] received, process exiting).
Please let me know if you need a cap file.

Thank you & regards

this was either fixed in 2.2.x or 2.3 with newer dhcp6c
