Struct gio::DBusAuthObserver
source · #[repr(transparent)]pub struct DBusAuthObserver { /* private fields */ }
Expand description
The DBusAuthObserver
type provides a mechanism for participating
in how a DBusServer
(or a DBusConnection
) authenticates remote
peers. Simply instantiate a DBusAuthObserver
and connect to the
signals you are interested in. Note that new signals may be added
in the future
Controlling Authentication Mechanisms
By default, a DBusServer
or server-side DBusConnection
will allow
any authentication mechanism to be used. If you only
want to allow D-Bus connections with the EXTERNAL
mechanism,
which makes use of credentials passing and is the recommended
mechanism for modern Unix platforms such as Linux and the BSD family,
you would use a signal handler like this:
⚠️ The following code is in C ⚠️
static gboolean
on_allow_mechanism (GDBusAuthObserver *observer,
const gchar *mechanism,
gpointer user_data)
{
if (g_strcmp0 (mechanism, "EXTERNAL") == 0)
{
return TRUE;
}
return FALSE;
}
Controlling Authorization # {auth
-observer}
By default, a DBusServer
or server-side DBusConnection
will accept
connections from any successfully authenticated user (but not from
anonymous connections using the ANONYMOUS
mechanism). If you only
want to allow D-Bus connections from processes owned by the same uid
as the server, since GLib 2.68, you should use the
DBusServerFlags::AUTHENTICATION_REQUIRE_SAME_USER
flag. It’s equivalent
to the following signal handler:
⚠️ The following code is in C ⚠️
static gboolean
on_authorize_authenticated_peer (GDBusAuthObserver *observer,
GIOStream *stream,
GCredentials *credentials,
gpointer user_data)
{
gboolean authorized;
authorized = FALSE;
if (credentials != NULL)
{
GCredentials *own_credentials;
own_credentials = g_credentials_new ();
if (g_credentials_is_same_user (credentials, own_credentials, NULL))
authorized = TRUE;
g_object_unref (own_credentials);
}
return authorized;
}
