Implemented Interfaces

PolkitAuthority implements GInitable and GAsyncInitable.

Description

PolkitAuthority is used for checking whether a given subject is authorized to perform a given action. Typically privileged system daemons or suid helpers will use this when handling requests from untrusted clients.

User sessions can register an authentication agent with the authority. This is used for requests from untrusted clients where system policy requires that the user needs to acknowledge (through proving he is the user or the administrator) a given action. See PolkitAgentListener and PolkitAgentSession for details.

Functions

polkit_authority_get_async ()

void
polkit_authority_get_async (GCancellable *cancellable,
                            GAsyncReadyCallback callback,
                            gpointer user_data);

Asynchronously gets a reference to the authority.

This is an asynchronous failable function. When the result is ready, callback will be invoked in the thread-default main loop of the thread you are calling this method from and you can use polkit_authority_get_finish() to get the result. See polkit_authority_get_sync() for the synchronous version.

Parameters

cancellable	A GCancellable or `NULL`.	[allow-none]
callback	A GAsyncReadyCallback to call when the request is satisfied.
user_data	The data to pass to `callback` .

polkit_authority_get_finish ()

PolkitAuthority *
polkit_authority_get_finish (GAsyncResult *res,
                             GError **error);

Finishes an operation started with polkit_authority_get_async().

Parameters

res	A GAsyncResult obtained from the GAsyncReadyCallback passed to `polkit_authority_get_async()`.
error	Return location for error or `NULL`.	[allow-none]

Returns

A PolkitAuthority. Free it with g_object_unref() when done with it.

polkit_authority_get_sync ()

PolkitAuthority *
polkit_authority_get_sync (GCancellable *cancellable,
                           GError **error);

Synchronously gets a reference to the authority.

This is a synchronous failable function - the calling thread is blocked until a reply is received. See polkit_authority_get_async() for the asynchronous version.

Parameters

cancellable	A GCancellable or `NULL`.	[allow-none]
error	Return location for error or `NULL`.	[allow-none]

Returns

A PolkitAuthority. Free it with g_object_unref() when done with it.

Parameters

authority

Returns

NULL or a string that should be freed with g_free().

[allow-none]

polkit_authority_get_backend_name ()

void
polkit_authority_check_authorization (PolkitAuthority *authority,
                                      PolkitSubject *subject,
                                      const gchar *action_id,
                                      PolkitDetails *details,

                                      GCancellable *cancellable,
                                      GAsyncReadyCallback callback,
                                      gpointer user_data);

Asynchronously checks if subject is authorized to perform the action represented by action_id .

Note that POLKIT_CHECK_AUTHORIZATION_FLAGS_ALLOW_USER_INTERACTION SHOULD be passed ONLY if the event that triggered the authorization check is stemming from an user action, e.g. the user pressing a button or attaching a device.

When the operation is finished, callback will be invoked in the

thread-default main loop of the thread you are calling this method

from. You can then call polkit_authority_check_authorization_finish() to get the result of the operation.

Known keys in details include polkit.message and polkit.gettext_domain that can be used to override the message shown to the user. See the documentation for the D-Bus method for more details.

If details is non-empty then the request will fail with POLKIT_ERROR_FAILED unless the process doing the check itsef is sufficiently authorized (e.g. running as uid 0).

Parameters

authority	A PolkitAuthority.
subject	A PolkitSubject.
action_id	The action to check for.
details	Details about the action or `NULL`.	[allow-none]
flags	A set of PolkitCheckAuthorizationFlags.
cancellable	A GCancellable or `NULL`.	[allow-none]
callback	A GAsyncReadyCallback to call when the request is satisfied.
user_data	The data to pass to `callback` .

polkit_authority_check_authorization_finish ()

PolkitAuthorizationResult *
polkit_authority_check_authorization_finish
                               (PolkitAuthority *authority,
                                GAsyncResult *res,
                                GError **error);

Finishes checking if a subject is authorized for an action.

Parameters

authority	A PolkitAuthority.
res	A GAsyncResult obtained from the callback.
error	Return location for error or `NULL`.	[allow-none]

Returns

A PolkitAuthorizationResult or NULL if error is set. Free with g_object_unref().

[transfer full]

polkit_authority_check_authorization_sync ()

PolkitAuthorizationResult *
polkit_authority_check_authorization_sync
                               (PolkitAuthority *authority,
                                PolkitSubject *subject,
                                const gchar *action_id,
                                PolkitDetails *details,
                                PolkitCheckAuthorizationFlags flags,
                                GCancellable *cancellable,
                                GError **error);

Checks if subject is authorized to perform the action represented by action_id .

Note the calling thread is blocked until a reply is received. You should therefore NEVER do this from a GUI thread or a daemon service thread when using the POLKIT_CHECK_AUTHORIZATION_FLAGS_ALLOW_USER_INTERACTION flag. This is because it may potentially take minutes (or even hours) for the operation to complete because it involves waiting for the user to authenticate.

Known keys in details include polkit.message and polkit.gettext_domain that can be used to override the message shown to the user. See the documentation for the D-Bus method for more details.

Parameters

authority	A PolkitAuthority.
subject	A PolkitSubject.
action_id	The action to check for.
details	Details about the action or `NULL`.	[allow-none]
flags	A set of PolkitCheckAuthorizationFlags.
cancellable	A GCancellable or `NULL`.	[allow-none]
error	Return location for error or `NULL`.	[allow-none]

Returns

A PolkitAuthorizationResult or NULL if error is set. Free with g_object_unref().
