Tim, I have a question for you. When you connect through 
network-manager-openconnect-gnome, and type
systemd-resolve --status, what is your link name called? Something like 'tun0' 
or 'tap1' or the like?

Because I've been looking around at the openconnect wiki at 
http://www.infradead.org/openconnect/building.html, and it seems like 
openconnect requires tun/tap drivers. So theoretically, it should have worked 
with the original patch containing just the conditional expression:
if (link_type == NM_LINK_TYPE_TUN || link_type == NM_LINK_TYPE_TAP)
As in, this should evaluate to true as the link should be of type tun or tap.

It seems like the updated patch containing the conditional expression
if (link_type == NM_LINK_TYPE_TUN || link_type == NM_LINK_TYPE_TAP || link_type 
== NM_LINK_TYPE_GRE || link_type == NM_LINK_TYPE_GRETAP)
might, however, help address users of 
network-manager-vpnc/network-manager-vpnc-gnome. If anyone uses 
network-manager-vpnc/network-manager-vpnc-gnome, let me know if the newer patch 
containing the cases for NM_LINK_TYPE_GRE and NM_LINK_TYPE_GRETAP fixes DNS 
leaks for you on a Cisco PPTP/IPsec VPN. I am unable to test this out as I 
don't have access to any such Cisco VPN services.

Anyway, if the network manager doesn't correctly register the
openconnect interface as being link type TUN or TAP, I don't really know
how to fix it as that could be a problem on network-manager-
openconnect's end or the result of some way it doesn't properly notify
the network manager.
