NetworkManager r3829 - in trunk: . introspection src src/dhcp-manager

Author: dcbw
Date: Thu Jul 17 17:04:13 2008
New Revision: 3829
URL: http://svn.gnome.org/viewvc/NetworkManager?rev=3829&view=rev

Log:
2008-07-17  Dan Williams  <dcbw redhat com>

	* introspection/Makefile.am
	  introspection/nm-device.xml
	  introspection/nm-dhcp4-config.xml
		- Add bits for the DHCP4Config property of the device, and the DHCP4Config
			itself
	* src/nm-device-interface.c
	  src/nm-device-interface.h
		- Add the DHCP4Config property

	* src/nm-device.c
		- Keep track of DHCP4 options via a new DHCP4Config property and notify
			D-Bus clients when it changes

	* src/nm-dhcp4-config.c
	  src/nm-dhcp4-config.h
		- Simple object to store DHCP4 options, export them over D-Bus, and
			notify when they change

	* src/dhcp-manager/nm-dhcp-manager.c
	  src/dhcp-manager/nm-dhcp-manager.h
		- (nm_dhcp_manager_set_dhcp4_config, copy_dhcp4_config_option): copy and
			filter server-returned DHCP options into an NMDHCP4Config object
