[SOLVED] NetworkManager (1.8.0-1) ignores dns-search

Hello !

For the context : I run my own DNS resolver, and I use the domain "lan" for all my machines on the network.
To avoid typing .lan each time, I use the "dns-search" parameter in NetworkManager config (stored in /etc/NetworkManager/system-connections).

Everything worked fine, until 1.8.0-1 ... now NetworkManager ignores the dns-search parameter in the config file :

dns=192.168.0.1;
dns-search=lan;

These settings should lead to this resolv.conf :

# Generated by NetworkManager
search lan
nameserver 192.168.0.1

but instead, I got this :

# Generated by NetworkManager
nameserver 192.168.0.1

I can edit the config via nmcli, but the changes have no effect, even if I restart the service or do a manual down/up of the connection via nmcli.

For me, that seems to be a bug, but maybe I miss something ?

I finally got the answer, thanks to bagar11 and Jan de Groot :

The new version of NetworkManager validates the dns-search domain against the Public Suffix List, that means that you can no longer use a dummy domain (and a dummy TLD) for dns-search.
