NetworkManager D-Bus API Types

NetworkManager D-Bus API Types

enum NMVersionInfoCapability

%_NM_VERSION_INFO_CAPABILITY_UNUSED: a dummy capability. It has no meaning, don't use it.

Currently no enum values are defined. These capabilities are exposed on D-Bus in the "VersionInfo" bit field.

Since: 1.42

Values


enum NMCapability

NMCapability names the numbers in the Capabilities property. Capabilities are positive numbers. They are part of stable API and a certain capability number is guaranteed not to change.

The range 0x7000 - 0x7FFF of capabilities is guaranteed not to be used by upstream NetworkManager. It could thus be used for downstream extensions.

Since: 1.6

Values

NM_CAPABILITY_TEAM

= 1

Teams can be managed. This means the team device plugin is loaded.

 

NM_CAPABILITY_OVS

= 2

OpenVSwitch can be managed. This means the OVS device plugin is loaded. Since: 1.24.

 

enum NMState

NMState values indicate the current overall networking state.

Values

NM_STATE_UNKNOWN

= 0

Networking state is unknown. This indicates a daemon error that makes it unable to reasonably assess the state. In such event the applications are expected to assume Internet connectivity might be present and not disable controls that require network access. The graphical shells may hide the network accessibility indicator altogether since no meaningful status indication can be provided.

 

NM_STATE_ASLEEP

= 10

Networking is not enabled, the system is being suspended or resumed from suspend.

 

NM_STATE_DISCONNECTED

= 20

There is no active network connection. The graphical shell should indicate no network connectivity and the applications should not attempt to access the network.

 

NM_STATE_DISCONNECTING

= 30

Network connections are being cleaned up. The applications should tear down their network sessions.

 

NM_STATE_CONNECTING

= 40

A network connection is being started The graphical shell should indicate the network is being connected while the applications should still make no attempts to connect the network.

 

NM_STATE_CONNECTED_LOCAL

= 50

There is only local IPv4 and/or IPv6 connectivity, but no default route to access the Internet. The graphical shell should indicate no network connectivity.

 

NM_STATE_CONNECTED_SITE

= 60

There is only site-wide IPv4 and/or IPv6 connectivity. This means a default route is available, but the Internet connectivity check (see "Connectivity" property) did not succeed. The graphical shell should indicate limited network connectivity.

 

NM_STATE_CONNECTED_GLOBAL

= 70

There is global IPv4 and/or IPv6 Internet connectivity This means the Internet connectivity check succeeded, the graphical shell should indicate full network connectivity.

 

enum NMConnectivityState

Values

NM_CONNECTIVITY_UNKNOWN

= 0

Network connectivity is unknown. This means the connectivity checks are disabled (e.g. on server installations) or has not run yet. The graphical shell should assume the Internet connection might be available and not present a captive portal window.

 

NM_CONNECTIVITY_NONE

= 1

The host is not connected to any network. There's no active connection that contains a default route to the internet and thus it makes no sense to even attempt a connectivity check. The graphical shell should use this state to indicate the network connection is unavailable.

 

NM_CONNECTIVITY_PORTAL

= 2

The Internet connection is hijacked by a captive portal gateway. The graphical shell may open a sandboxed web browser window (because the captive portals typically attempt a man-in-the-middle attacks against the https connections) for the purpose of authenticating to a gateway and retrigger the connectivity check with CheckConnectivity() when the browser window is dismissed.

 

NM_CONNECTIVITY_LIMITED

= 3

The host is connected to a network, does not appear to be able to reach the full Internet, but a captive portal has not been detected.

 

NM_CONNECTIVITY_FULL

= 4

The host is connected to a network, and appears to be able to reach the full Internet.

enum NMMetered

The NMMetered enum has two different purposes: one is to configure "connection.metered" setting of a connection profile in NMSettingConnection, and the other is to express the actual metered state of the NMDevice at a given moment.

For the connection profile only NM_METERED_UNKNOWN, NM_METERED_NO and NM_METERED_YES are allowed.

The device's metered state at runtime is determined by the profile which is currently active. If the profile explicitly specifies NM_METERED_NO or NM_METERED_YES, then the device's metered state is as such. If the connection profile leaves it undecided at NM_METERED_UNKNOWN (the default), then NetworkManager tries to guess the metered state, for example based on the device type or on DHCP options (like Android devices exposing a "ANDROID_METERED" DHCP vendor option). This then leads to either NM_METERED_GUESS_NO or NM_METERED_GUESS_YES.

Most applications probably should treat the runtime state NM_METERED_GUESS_YES like NM_METERED_YES, and all other states as not metered.

Note that the per-device metered states are then combined to a global metered state. This is basically the metered state of the device with the best default route. However, that generalization of a global metered state may not be correct if the default routes for IPv4 and IPv6 are on different devices, or if policy routing is configured. In general, the global metered state tries to express whether the traffic is likely metered, but since that depends on the traffic itself, there is not one answer in all cases. Hence, an application may want to consider the per-device's metered states.

Since: 1.2

enum NMCheckpointCreateFlags

The flags for CheckpointCreate call

Since: 1.12: Public since 1.4, g-ir since 1.12.

Values

NM_CHECKPOINT_CREATE_FLAG_NONE

= 0

no flags

 

NM_CHECKPOINT_CREATE_FLAG_DESTROY_ALL

= 0x01

when creating a new checkpoint, destroy all existing ones.

 

NM_CHECKPOINT_CREATE_FLAG_DELETE_NEW_CONNECTIONS

= 0x02

upon rollback, delete any new connection added after the checkpoint. Since: 1.6.

 

NM_CHECKPOINT_CREATE_FLAG_DISCONNECT_NEW_DEVICES

= 0x04

upon rollback, disconnect any new device appeared after the checkpoint. Since: 1.6.

 

NM_CHECKPOINT_CREATE_FLAG_ALLOW_OVERLAPPING

= 0x08

by default, creating a checkpoint fails if there are already existing checkpoints that reference the same devices. With this flag, creation of such checkpoints is allowed, however, if an older checkpoint that references overlapping devices gets rolled back, it will automatically destroy this checkpoint during rollback. This allows to create several overlapping checkpoints in parallel, and rollback to them at will. With the special case that rolling back to an older checkpoint will invalidate all overlapping younger checkpoints. This opts-in that the checkpoint can be automatically destroyed by the rollback of an older checkpoint. Since: 1.12.

 

NM_CHECKPOINT_CREATE_FLAG_NO_PRESERVE_EXTERNAL_PORTS

= 0x10

during rollback, by default externally added ports attached to bridge devices are preserved. With this flag, the rollback detaches all external ports. This only has an effect for bridge ports. Before 1.38, this was the default behavior. Since: 1.38.

 

NM_CHECKPOINT_CREATE_FLAG_TRACK_INTERNAL_GLOBAL_DNS

= 0x20

during rollback, by default changes to global DNS via D-BUS interface are preserved. With this flag, the rollback reverts the global DNS changes made via D-Bus interface. Global DNS defined in [global-dns] section of NetworkManager.conf is not impacted by this flag. Since: 1.48.

 

enum NMRollbackResult

The result of a checkpoint Rollback() operation for a specific device.

Since: 1.4

Values

NM_ROLLBACK_RESULT_OK

= 0

the rollback succeeded.

= 1

the device no longer exists.

 

NM_ROLLBACK_RESULT_ERR_DEVICE_UNMANAGED

= 2

the device is now unmanaged.

 

NM_ROLLBACK_RESULT_ERR_FAILED

= 3

enum NMSettingsConnectionFlags

Flags describing the current activation state.

Since: 1.12

Values

NM_SETTINGS_CONNECTION_FLAG_NONE

= 0

an alias for numeric zero, no flags set.

 

NM_SETTINGS_CONNECTION_FLAG_UNSAVED

= 0x01

the connection is not saved to disk. That either means, that the connection is in-memory only and currently is not backed by a file. Or, that the connection is backed by a file, but has modifications in-memory that were not persisted to disk.

 

NM_SETTINGS_CONNECTION_FLAG_NM_GENERATED

= 0x02

A connection is "nm-generated" if it was generated by NetworkManger. If the connection gets modified or saved by the user, the flag gets cleared. A nm-generated is also unsaved and has no backing file as it is in-memory only.

 

NM_SETTINGS_CONNECTION_FLAG_VOLATILE

= 0x04

The connection will be deleted when it disconnects. That is for in-memory connections (unsaved), which are currently active but deleted on disconnect. Volatile connections are always unsaved, but they are also no backing file on disk and are entirely in-memory only.

 

NM_SETTINGS_CONNECTION_FLAG_EXTERNAL

= 0x08

the profile was generated to represent an external configuration of a networking device. Since: 1.26.

 

enum NMActivationStateFlags

Flags describing the current activation state.

Since: 1.10

Values

NM_ACTIVATION_STATE_FLAG_NONE

= 0

an alias for numeric zero, no flags set.

 

NM_ACTIVATION_STATE_FLAG_IS_MASTER

= 0x1

the device is a master.

 

NM_ACTIVATION_STATE_FLAG_IS_SLAVE

= 0x2

the device is a slave.

 

NM_ACTIVATION_STATE_FLAG_LAYER2_READY

= 0x4

layer2 is activated and ready.

 

NM_ACTIVATION_STATE_FLAG_IP4_READY

= 0x8

IPv4 setting is completed.

 

NM_ACTIVATION_STATE_FLAG_IP6_READY

= 0x10

IPv6 setting is completed.

 

NM_ACTIVATION_STATE_FLAG_MASTER_HAS_SLAVES

= 0x20

The master has any slave devices attached. This only makes sense if the device is a master.

 

NM_ACTIVATION_STATE_FLAG_LIFETIME_BOUND_TO_PROFILE_VISIBILITY

= 0x40

the lifetime of the activation is bound to the visibility of the connection profile, which in turn depends on "connection.permissions" and whether a session for the user exists. Since: 1.16.

 

NM_ACTIVATION_STATE_FLAG_EXTERNAL

= 0x80

the active connection was generated to represent an external configuration of a networking device. Since: 1.26.

 

enum NMSettingsAddConnection2Flags

Numeric flags for the "flags" argument of AddConnection2() D-Bus API.

Since: 1.20

Values

NM_SETTINGS_ADD_CONNECTION2_FLAG_NONE

= 0

an alias for numeric zero, no flags set.

 

NM_SETTINGS_ADD_CONNECTION2_FLAG_TO_DISK

= 0x1

to persist the connection to disk.

 

NM_SETTINGS_ADD_CONNECTION2_FLAG_IN_MEMORY

= 0x2

to make the connection in-memory only.

 

NM_SETTINGS_ADD_CONNECTION2_FLAG_BLOCK_AUTOCONNECT

= 0x20

usually, when the connection has autoconnect enabled and gets added, it becomes eligible to autoconnect right away. Setting this flag, disables autoconnect until the connection is manually activated.

 

enum NMSettingsUpdate2Flags

Since: 1.12

Values

NM_SETTINGS_UPDATE2_FLAG_NONE

= 0

an alias for numeric zero, no flags set.

 

NM_SETTINGS_UPDATE2_FLAG_TO_DISK

= 0x1

to persist the connection to disk.

 

NM_SETTINGS_UPDATE2_FLAG_IN_MEMORY

= 0x2

makes the profile in-memory. Note that such profiles are stored in keyfile format under /run. If the file is already in-memory, the file in /run is updated in-place. Otherwise, the previous storage for the profile is left unchanged on disk, and the in-memory copy shadows it. Note that the original filename of the previous persistent storage (if any) is remembered. That means, when later persisting the profile again to disk, the file on disk will be overwritten again. Likewise, when finally deleting the profile, both the storage from /run and persistent storage are deleted (or if the persistent storage does not allow deletion, and nmmeta file is written to mark the UUID as deleted).

 

NM_SETTINGS_UPDATE2_FLAG_IN_MEMORY_DETACHED

= 0x4

this is almost the same as %NM_SETTINGS_UPDATE2_FLAG_IN_MEMORY, with one difference: when later deleting the profile, the original profile will not be deleted. Instead a nmmeta file is written to /run to indicate that the profile is gone. Note that if such a nmmeta tombstone file exists and hides a file in persistent storage, then when re-adding the profile with the same UUID, then the original storage is taken over again.

 

NM_SETTINGS_UPDATE2_FLAG_IN_MEMORY_ONLY

= 0x8

this is like %NM_SETTINGS_UPDATE2_FLAG_IN_MEMORY, but if the connection has a corresponding file on persistent storage, the file will be deleted right away. If the profile is later again persisted to disk, a new, unused filename will be chosen.

 

NM_SETTINGS_UPDATE2_FLAG_VOLATILE

= 0x10

This can be specified with either %NM_SETTINGS_UPDATE2_FLAG_IN_MEMORY, %NM_SETTINGS_UPDATE2_FLAG_IN_MEMORY_DETACHED or %NM_SETTINGS_UPDATE2_FLAG_IN_MEMORY_ONLY. After making the connection in-memory only, the connection is marked as volatile. That means, if the connection is currently not active it will be deleted right away. Otherwise, it is marked to for deletion once the connection deactivates. A volatile connection cannot autoactivate again (because it's about to be deleted), but a manual activation will clear the volatile flag.

 

NM_SETTINGS_UPDATE2_FLAG_BLOCK_AUTOCONNECT

= 0x20

usually, when the connection has autoconnect enabled and is modified, it becomes eligible to autoconnect right away. Setting this flag, disables autoconnect until the connection is manually activated.

 

NM_SETTINGS_UPDATE2_FLAG_NO_REAPPLY

= 0x40

when a profile gets modified that is currently active, then these changes don't take effect for the active device unless the profile gets reactivated or the configuration reapplied. There are two exceptions: by default "connection.zone" and "connection.metered" properties take effect immediately. Specify this flag to prevent these properties to take effect, so that the change is restricted to modify the profile. Since: 1.20.

 

enum NMDeviceReapplyFlags

Flags for the Reapply() D-Bus call of a device and nm_device_reapply_async().

Since: 1.42

enum NMManagerReloadFlags

Flags for the manager Reload() call.

Since: 1.22

Values

NM_MANAGER_RELOAD_FLAG_NONE

= 0

an alias for numeric zero, no flags set. This reloads everything that is supported and is identical to a SIGHUP.

 

NM_MANAGER_RELOAD_FLAG_CONF

= 0x1

reload the NetworkManager.conf configuration from disk. Note that this does not include connections, which can be reloaded via Setting's ReloadConnections().

 

NM_MANAGER_RELOAD_FLAG_DNS_RC

= 0x2

update DNS configuration, which usually involves writing /etc/resolv.conf anew.

 

NM_MANAGER_RELOAD_FLAG_DNS_FULL

= 0x4

means to restart the DNS plugin. This is for example useful when using dnsmasq plugin, which uses additional configuration in /etc/NetworkManager/dnsmasq.d. If you edit those files, you can restart the DNS plugin. This action shortly interrupts name resolution.

 

NM_MANAGER_RELOAD_FLAG_ALL

= 0x7

all flags.

 

enum NMDeviceInterfaceFlags

Flags for a network interface.

Since: 1.22

Values

NM_DEVICE_INTERFACE_FLAG_NONE

= 0x1

A Wireless LAN device or rfkill switch is detected in the system.

 

NM_RADIO_FLAG_WWAN_AVAILABLE

= 0x2

enum NMMptcpFlags

Since: 1.40

Values

NM_MPTCP_FLAGS_NONE

= 0

The default, meaning that no MPTCP flags are set.

 

NM_MPTCP_FLAGS_DISABLED

= 0x1

don't configure MPTCP endpoints on the device.

 

NM_MPTCP_FLAGS_ENABLED

= 0x2

MPTCP is enabled and endpoints will be configured. This flag is implied if any of the other flags indicate that MPTCP is enabled and therefore in most cases unnecessary. Note that if "/proc/sys/net/mptcp/enabled" sysctl is disabled, MPTCP handling is disabled despite this flag. This can be overruled with the "also-without-sysctl" flag. Note that by default interfaces that don't have a default route are excluded from having MPTCP endpoints configured. This can be overruled with the "also-without-default-route" and this affects endpoints per address family.

 

NM_MPTCP_FLAGS_ALSO_WITHOUT_SYSCTL

= 0x4

even if MPTCP handling is enabled via the "enabled" flag, it is ignored unless "/proc/sys/net/mptcp/enabled" is on. With this flag, MPTCP endpoints will be configured regardless of the sysctl setting.

 

NM_MPTCP_FLAGS_ALSO_WITHOUT_DEFAULT_ROUTE

= 0x8

even if MPTCP handling is enabled via the "enabled" flag, it is ignored per-address family unless NetworkManager configures a default route. With this flag, NetworkManager will also configure MPTCP endpoints if there is no default route. This takes effect per-address family.

 

NM_MPTCP_FLAGS_SIGNAL

= 0x10

Flag for the MPTCP endpoint. The endpoint will be announced/signaled to each peer via an MPTCP ADD_ADDR sub-option.

 

NM_MPTCP_FLAGS_SUBFLOW

= 0x20

Flag for the MPTCP endpoint. If additional subflow creation is allowed by the MPTCP limits, the MPTCP path manager will try to create an additional subflow using this endpoint as the source address after the MPTCP connection is established.

 

NM_MPTCP_FLAGS_BACKUP

= 0x40

Flag for the MPTCP endpoint. If this is a subflow endpoint, the subflows created using this endpoint will have the backup flag set during the connection process. This flag instructs the peer to only send data on a given subflow when all non-backup subflows are unavailable. This does not affect outgoing data, where subflow priority is determined by the backup/non-backup flag received from the peer

 

NM_MPTCP_FLAGS_FULLMESH

= 0x80

Flag for the MPTCP endpoint. If this is a subflow endpoint and additional subflow creation is allowed by the MPTCP limits, the MPTCP path manager will try to create an additional subflow for each known peer address, using this endpoint as the source address. This will occur after the MPTCP connection is established. If the peer did not announce any additional addresses using the MPTCP ADD_ADDR sub-option, this will behave the same as a plain subflow endpoint. When the peer does announce addresses, each received ADD_ADDR sub-option will trigger creation of an additional subflow to generate a full mesh topology.
