Since the same interface could be used for both DHCPv4 and DHCPv6 we
can't just use 'iface' for tracking DHCP client lease changes. Instead
use a generated client ID, and track DHCP events based on the client's
PID instead of interface name.
In the past networkmanager did not allow to manually disconnect devices.
Manually disconnected devices will not be automatically reconnected until one
of the following events occur:
1. user activates a connection for the currently disconnected device
2. network manager awakes from hibernate/suspend
3. network manager is restarted (e.g. reboot)
Add a Disconnect method to generic NMDevice dbus interface; set a new private
autoconnect_inhibit flag if Disconnect method is called through dbus.
Based on this auto activation for devices gets inhibited until one
of the above events occur.
Instead of doing this in every device subclass, do it in the NMDevice
superclass. nm_device_can_activate() already did the same logic that
each of the subclass device_state_changed() handlers were doing to
figure out whether they could do the transition from unavailable
to disconnected, so just use that in NMDevice and kill lots of code.
Automatic IPv6 configuration is handled by the kernel, but to
integrate it properly with NetworkManager, we need to watch what the
kernel does to see whether or not it was successful (so that we can
let the user know if there is no IPv6 router present, for example).
NMIP6Manager takes care of this.
Mark activation requests that contain connections to be assumed,
and use that to short-circuit various parts of the activation
process by not touching various device attributes, since they
are already set up. Also ensure the device is not deactivated
when it initially becomes managed, because that would kill the
connection we are about to assume.
This allows a device (or a companion) to signal that it is not a good
time for a specific device to autoconnect to a network.
The OLPC mesh device will use this to prevent automatic connection
to WLAN networks while the mesh device is active.
The only thing that doesn't work yet is the system-settings service's
"auto eth" connections for ethernet devices that don't have an existing
connection. Might also have issues with unmanaged devices that can't
provide a MAC address until they are brought up, but we'll see.
device_start() would unconditionally transition the device to UNAVAILABLE
no matter what the initial managed setting was. There was a short window
for a race with HAL where device_start() wouldn't get canceled if HAL
was starting up in parallel with NetworkManager.
Fix issues with crappy wifi drivers which send a stream of associate
events before NM can schedule the next activation stage, which actually
scheduled *multiple* next stages. Only allow one stage to be scheduled at
at time, and don't schedule the same stage again if it's already next up
to the plate.
Based on patches by Johan Bilien <jobi@via.ecp.fr>,
nick loeve <trickie@gmail.com>, and Roy Marples <roy@marples.name>
with significant changes for dhclient formatting and test cases.
Note that dhclient needs help before it can actually parse
classless static routes by adding the following to the
dhclient.conf file:
option rfc3442-classless-static-routes code 121 = array of unsigned integer 8;
Fix deletion of VPN gateway route on DHCP renew (bgo #558133)
* src/NetworkManagerSystem.c
src/NetworkManagerSystem.h
- (nm_system_device_set_ip4_route): return the route that was added
- (nm_system_add_ip4_vpn_gateway_route): make add_vpn_gateway_route()
public, clean up, and return the route that was added
- (nm_system_apply_ip4_config): remove VPN related stuff to simplify,
since nm_system_add_ip4_vpn_gateway_route() is now available; add
flags to allow only certain attributes of the NMIP4Config to be
applied
* src/nm-device.c
- (handle_dhcp_lease_change): don't touch the DHCP4 config on failure
- (nm_device_set_ip4_config): use nm_ip4_config_diff() to only apply
what's really changed between the old and new configs; don't export
the new IP4 config on failure; always send the DNS info to the
named manager
* src/vpn-manager/nm-vpn-connection.c
- (device_ip4_config_changed, nm_vpn_connection_new, dispose): track the
parent device's IP4Config and re-add the VPN gateway route when it
changes
- (nm_vpn_connection_ip4_config_get): add the VPN gateway route (since
nm_system_apply_ip4_config() no longer does) and cache it for later
- (connection_state_changed): move cleanup code to its own function
- (vpn_cleanup): delete any previously added VPN gateway route; and
re-apply the parent device's addresses and routes using
nm_system_apply_ip4_config(), not nm_device_set_ip4_config()

Ensure zombie children get cleaned up. To get notifications when children
die abnormally, g_spawn_async() requires G_SPAWN_DO_NOT_REAP_CHILD, but
that requires calling waitpid() yourself if you've removed the child watch
handler before the process has actually died, which NM needs to do in a few
places. So ensure that everything uses G_SPAWN_DO_NOT_REAP_CHILD and also
cleans up after the child when required. Should fix problems trying to
activate mobile broadband connections after a previous failure.
