2008-10-10 Dan Williams <dcbw@redhat.com> Rework default route handling to consolidate decisions in the policy, and to take active VPN connections into account when changing the default route (bgo #545912) * src/NetworkManager.c - (main): pass the vpn_manager to the policy so it knows about active VPN connections; clean up the named manager which wasn't done before * src/NetworkManagerPolicy.c src/NetworkManagerPolicy.h - (nm_policy_new): get a clue about the vpn_manager - (update_default_route): remove, fold into update_routing_and_dns() - (update_routing_and_dns): handle active VPN connections too; an active VPN connection becomes the default route if it does not have server-specified or user-specified custom routes. Otherwise, the best active device gets the default route - (vpn_connection_activated, vpn_connection_deactivated, nm_policy_new, nm_policy_destroy): track VPN connection activation and deactivation and update the default route when appropriate * src/NetworkManagerSystem.c src/NetworkManagerSystem.h - (nm_system_vpn_device_unset_from_ip4_config): remove, put functionality in the VPN connection itself - (nm_system_vpn_device_set_from_ip4_config, nm_system_device_set_from_ip4_config): merge together to make nm_system_apply_ip4_config() - (add_vpn_gateway_route): add a route to the VPN's external gateway via the parent device - (nm_system_apply_ip4_config): simplify - (add_ip4_route_to_gateway): new function; add a direct route to the gateway if needed - (nm_system_device_replace_default_ip4_route): simplify, break gateway route stuff out into add_ip4_route_to_gateway() for clarity * src/nm-device.c - (nm_device_set_ip4_config): update for nm_system_apply_ip4_config() * src/vpn-manager/nm-vpn-connection.c src/vpn-manager/nm-vpn-connection.h - (nm_vpn_connection_get_ip4_config, nm_vpn_connection_get_ip_iface, nm_vpn_connection_get_parent_device): add - (nm_vpn_connection_ip4_config_get): make the requirement of a tunnel device explicit - (connection_state_changed): update the named manager now that nm_system_vpn_device_unset_from_ip4_config() is gone; do something useful on errors * src/vpn-manager/nm-vpn-manager.c src/vpn-manager/nm-vpn-manager.h - Add a 'connection-activated' signal - (nm_vpn_manager_get_active_connections): new function; mainly for the policy to find out about active VPN connections git-svn-id: http://svn-archive.gnome.org/svn/NetworkManager/trunk@4167 4912f4e0-d625-0410-9fb7-b9a5a253dbdc

Order is (highest to lowest) wired, wireless, GSM, CDMA. - (update_routing_and_dns): new function; determine which device should have the default route, then update the routing table and DNS - (maybe_auto_activate_device): new function; if a device is now available for activation, find out what connection it would like to activate and do it - (schedule_activate_check): new function; if a device can be activated now, schedule the activation. Each device may have only one pending activation at a given time. - (device_state_changed): if activation was canceled, try again, possibly with another connection; if the device was activated, update routing and DNS; if the device was deactivated, try again with another connection - (device_carrier_changed): if there is no carrier, deactivate the device; otherwise schedule an activation check for the device - (wireless_networks_changed): schedule an activation check for the device - (device_added): keep track of the signal handler IDs so they can be removed when the device goes away - (device_removed): remove any signal handlers that might be attached to the device; update routing and DNS - (schedule_activate_all): new function - (connections_added, connection_added, connection_updated): when connections change, schedule all devices for an activation check - (connection_removed): when a device is deactivated because its connection was removed, schedule another activation check for it - (nm_policy_destroy): destroy pending activations and disconnect all device signal handlers * src/nm-manager.c - (nm_manager_activate_device): if the device was already actived, deactivate it - (deactivate_old_device): remove - (connection_added_default_handler, impl_manager_activate_device): don't deactivate other devices when activating this one * src/backends/NetworkManagerGentoo.c src/backends/NetworkManagerFrugalware.c src/backends/NetworkManagerPaldo.c src/backends/NetworkManagerRedHat.c src/backends/NetworkManagerSlackware.c src/backends/NetworkManagerArch.c src/backends/NetworkManagerSuSE.c src/backends/NetworkManagerDebian.c - (nm_system_get_mtu): remove; MTU should be provided through the distro's system settings service plugin instead - (nm_system_device_add_default_route_via_device): remove - (nm_system_device_add_default_route_via_device_with_iface): remove - (nm_system_device_replace_default_route): new function; call generic implementation * src/backends/NetworkManagerGeneric.c src/backends/NetworkManagerGeneric.h - (nm_generic_device_add_default_route_via_device, nm_generic_device_add_default_route_via_device_with_iface): remove - (nm_generic_device_replace_default_route): replace the default route with the given route via some gateway * src/NetworkManagerSystem.c src/NetworkManagerSystem.h - (nm_system_device_set_from_ip4_config): let the policy handle updates to routing and DNS; but set the MTU here - (nm_system_vpn_device_set_from_ip4_config): set the route with the ip_iface of the active device; use the standard MTU setting function - (nm_system_set_mtu): remove - (nm_system_device_set_mtu): consolidate MTU setting code in one place git-svn-id: http://svn-archive.gnome.org/svn/NetworkManager/trunk@3391 4912f4e0-d625-0410-9fb7-b9a5a253dbdc
