Private D-Bus interface used by secret agents that store and provide secrets to NetworkManager. If an agent provides secrets to NetworkManager as part of connection creation, and the some of those secrets are "agent owned" the agent should store those secrets itself and should not expect its SaveSecrets() method to be called. SaveSecrets() will be called eg if some program other than the agent itself (like a connection editor) changes the secrets out of band. Retrieve and return stored secrets, if any, or request new secrets from the agent's user. Nested settings maps containing the connection for which secrets are being requested. This may contain system-owned secrets if the agent has successfully authenticated to modify system network settings and the GetSecrets request flags allow user interaction. Object path of the connection for which secrets are being requested. Setting name for which secrets are being requested. Array of strings of key names in the requested setting for which NetworkManager thinks a secrets may be required, and/or well-known identifiers and data that may be useful to the client in processing the secrets request. The Agent should return any secrets it has, or that it thinks are required, regardless of what hints NetworkManager sends in this request. Flags which modify the behavior of the secrets request. If true, new secrets are assumed to be invalid or incorrect, and the agent should ask the user for new secrets. If false, existing secrets should be retrieved from storage and returned without interrupting the user. Nested settings maps containing secrets. Each setting MUST contain at least the 'name' field, containing the name of the setting, and one or more secrets. Flags modifying the behavior of GetSecrets request. No special behavior; by default no user interaction is allowed and requests for secrets are fulfilled from persistent storage, or if no secrets are available an error is returned. Allows the request to interact with the user, possibly prompting via UI for secrets if any are required, or if none are found in persistent storage. Explicitly prompt for new secrets from the user. This flag signals that NetworkManager thinks any existing secrets are invalid or wrong. This flag implies that interaction is allowed. Set if the request was initiated by user-requested action via the D-Bus interface, as opposed to automatically initiated by NetworkManager in response to (for example) scan results or carrier changes. Cancel a pending GetSecrets request for secrets of the given connection. Any matching request should be canceled. Object path of the connection for which, if secrets are being requested, the request should be canceled. Setting name for which secrets for this connection were originally being requested. Save given secrets to backing storage. Nested settings maps containing the entire connection (including secrets), for which the agent should save the secrets to backing storage. This method will not be called when the agent itself is the process creating or updating a connection; in that case the agent is assumed to have already saved those secrets since it had them already. Object path of the connection for which the agent should save secrets to backing storage. Delete secrets from backing storage. Nested settings maps containing the connection properties (sans secrets), for which the agent should delete the secrets from backing storage. Object path of the connection for which the agent should delete secrets from backing storage.
