It is bound to autoconnect_inhibit private variable (has opposite meaning).
While 'Autoconnect' is TRUE (default value) the device can automatically
activate a connection. If it is changed to FALSE, the device will not
auto-activate until 'Autoconnect' is TRUE again.
Disconnect() method sets 'Autoconnect' to FALSE. NMPolicy monitors the property
and schedules auto activation when FALSE->TRUE transition is made.
When NM was registering all of its enum types by hand, it was using
NamesLikeThis rather than the default names-like-this for the "nick"
values. When we switched to using glib-mkenums, this resulted in
dbus-glib using different strings for the D-Bus error names, causing
compatibility problems.
Fix this by using glib-mkenums annotations to manually fix all the
enum values back to what they were before. (This can't be done in a
more automated way, because the old names aren't 100% consistent. Eg,
"UNKNOWN" frequently becomes "UnknownError" rather than just
"Unknown".)
We already have the master device kept in the active connection, so
we can just use that instead of having the Policy determine and set
it manually. This also should allow slaves to auto-activate their
master connections if the master is able to activate.
We'll want to eventually match (for VLAN) a given hardware address
that's not the device's hardware address. Only the device itself
knows which NMSetting should contain it's hardware address (ie
the 'wired' setting for NMDeviceEthernet, 'infiniband' for
NMDeviceInfiniband, etc) and VLANs take their hardware address
from the parent interface. So eventually we'll have VLAN
interfaces use these new arguments to ask their parent interface
to match the VLAN hardware address in a connection, since the
VLAN doesn't know (or need to know) what kind of interface it
really is underneath.
Rather than generating enum classes by hand (and complaining in each
file that "this should really be standard"), use glib-mkenums.
Unfortunately, we need a very new version of glib-mkenums in order to
deal with NM's naming conventions and to fix a few other bugs, so just
import that into the source tree temporarily.
Also, to simplify the use of glib-mkenums, import Makefile.glib from
https://bugzilla.gnome.org/654395.
To avoid having to run glib-mkenums for every subdirectory of src/,
add a new "generated" directory, and put the generated enums files
there.
Finally, use Makefile.glib for marshallers too, and generate separate
ones for libnm-glib and NetworkManager.
Allows clients to retrieve the reason a device changed to
the given state along with the state itself, preventing
race conditions if the state were retrieved separately
from the reason. Reason codes were not previously
accessible without listening to the StateChanged signal.
Adds a new "master" property to NMActiveConnection containing the path
of the master NMDevice if the connection has a master.

There are now three places we need delayed state transitions:
1) unavailable to disconnected
2) failed to disconnected
3) bond unavailable to disconnected
(3) wasn't doing a delayed transition, but we can't change
state from inside a state-change handler otherwise we may not
end up fully processing the current state chagne. So it needs a
delayed transition too; add some generic code to make that
easier to do.
Add an accessor for device rfkill type and use that instead of
GObject properties, and also use that accessor when claiming a
new device instead of checking NM_IS_DEVICE_xxxx(). Allows us
to move one step closer to making WiMAX a plugin.
Code is written generic enough to allow easy addition of further master/slave
relationships such as bridging relations.

For a slave to be activatetable the master connection must be present.
Activation of the slave is postponed until this condition is met.
Once the slave is being activated, a reference to the master connection
is acquired and held for the lifetime of the bond.
Changes v2:
- Made check_master_dependency() return TRUE/FALSE

Initial IP configuration can happen during ACTIVATED state if both
v4 and v6 are enabled, but one takes longer than the other. Thus
various checks throughout the code for IP_CONFIG were incorrect
since they depended on IP configuration only happening during the
IP_CONFIG state. Fix that by using a separate state for IP config
and using that state for various checks instead of the overall
device state.
It was somewhat pointless since the IP config is always known when
stage4 gets scheduled, so why not just pass the config to stage5
immediately? Also helps consolidate the v4/v6 failure handling
logic and makes the operational flow clearer where both v4 and
v6 are active and proceeding in parallel.
deactivate_quickly is misnamed these days; it was originally used
for quickly tearing down a device for sleep and such. But these
days it's used for the bulk of device deactivation. Only the wifi
class used the actual deactivate method. So combine the two and
make device implementations less complicated.
Given connection details, complete the connection as well as possible
using the given specific object and device, add it to system
settings, and activate it all in one method.
Otherwise it doesn't auto-scan and we get no network list. As a later
optimization, we could detect this, call iwmx_sdk_get_connected_network()
to get the current NSP, match that up with a connection, and "assume"
the connection like we do for Ethernet devices.
Instead of a bizare mechanism of signals back to the manager
object that used to be required because of the user/system settings
split, let each place that needs secrets request those secrets
itself. This flattens the secrets request process a ton and
the code flow significantly.
Previously the get secrets flow was something like this:
nm_act_request_get_secrets ()
nm_secrets_provider_interface_get_secrets ()
emits manager-get-secrets signal
provider_get_secerts ()
system_get_secrets ()
system_get_secrets_idle_cb ()
nm_sysconfig_connection_get_secrets ()
system_get_secrets_reply_cb ()
nm_secrets_provider_interface_get_secrets_result ()
signal failure or success
now instead we do something like this:
nm_agent_manager_get_secrets ()
nm_agent_manager_get_secrets ()
request_start_secrets ()
nm_sysconfig_connection_get_secrets ()
return failure or success to callback
Previously, NM reset permanent MAC to an interface while disconnecting. That
basically ignored MAC addresses set before NM started managing the interface.
Now, the initial MAC address is remembered and set back to the interface when
disconnecting.
This commit implements MAC cloning feature in NetworkManager. To support that,
'PermHwAddress' property is added into *.Device.Wired and *.Device.Wireless
interfaces. The permanent MAC address is obtained when creating the device, and
is used for 'locking' connections to the device. If a cloned MAC is specified
in connection to be activated, the MAC is set to the interface in stage1. While
disconecting, the permanent MAC is set back to the interface.
Where we can do so, let's use ifindex since that's actually unique
and doesn't change when the interface name changes. We already use
ifindex in a bunch of places, and netlink *only* uses ifindex, so
this will make it easier later when we move over to ifindexes fully.
nm_device_set_use_dhcp() and nm_device_get_use_dhcp() were somewhat
confusing and don't really reflect the new DHCP architecture with
NMDHCPClient. Now that timeout and state signals are specific to
the NMDHCPClient it doesn't make sense to check for DHCP use
in the callbacks for those signals since they'll never get called
if DHCP isn't in use. We might as well just keep the DHCP manager
around and check whether a DHCP client instance exists when we need
to figure out whether DHCP is in use.
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.
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.
