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)
