Subject: [PATCH 1/1] service: fix wrong refcounting in D-Bus handler for
Callback()
The Callback() D-Bus method is handled via a GDBus-generated skeleton
code in nm-libreswan-helper-service-dbus.c, function
_nmdbus_libreswan_helper_skeleton_handle_method_call(). The function
emits signal "handle-callback" to let the program handle the incoming
method. As documented in the GDoc comments, the signal handler must
return TRUE if it handles the call.
```
/**
* NMDBusLibreswanHelper::handle-callback:
* @object: A #NMDBusLibreswanHelper.
* @invocation: A #GDBusMethodInvocation.
* @arg_environment: Argument passed by remote caller.
* Signal emitted when a remote caller is invoking the Callback()
D-Bus method.
* If a signal handler returns %TRUE, it means the signal handler
will handle the invocation (e.g. take a reference to @invocation
and eventually call nmdbus_libreswan_helper_complete_callback()
or e.g. g_dbus_method_invocation_return_error() on it) and no
other signal handlers will run. If no signal handler handles the
invocation, the %G_DBUS_ERROR_UNKNOWN_METHOD error is returned.
* Returns: %G_DBUS_METHOD_INVOCATION_HANDLED or %TRUE if the
invocation was handled, %G_DBUS_METHOD_INVOCATION_UNHANDLED or
%FALSE to let other signal handlers run.
*/
```
At the moment, in case of error the handler first calls
nmdbus_libreswan_helper_complete_callback() which decreases the
refcount of "invocation", and then returns FALSE which tells the
skeleton code to return an error, also unreferencing the
invocation. This causes a crash.
Since the G_DBUS_METHOD_INVOCATION_HANDLED alias for TRUE is only
available since GLib 2.68 (while we target 2.36), just return TRUE.
Fixes: acb9eb9de50b ('service: process the configuration in the service, not the helper')
(cherry picked from commit 8ceb901719acac3778e1d76779d9c14289185157)
