[Bug 1343036] [NEW] Split DNS does not work (openconnect)

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

Split DNS seems not to be working with openconnect and network-manager.

Diagnostic that I have performed:
1. I replaced /usr/lib/NetworkManager/nm-openconnect-service-openconnect-helper with wrapper script and confirmed that enviroment variable CISCO_SPLIT_DNS is correct. 
2. I captured a log from dbus (see attachment) and it seems that plugin is sending all data atleast, but
3. Network manager sends wrong configuration to dnsmasq (see attachment).

Plugins sends split dns _domains_ as part of first dbus message (member=Config).
Then plugins send also second message (ip4 configuration (member=Ip4Config)), which has _domain_ section (corresponds to CISCO_DEF_DOMAIN), *and then only this domain gets used for dns resolution.* 
_domains_ from first section are ignored.
