From: "Daniel P. Berrange" <berrange(a)redhat.com&gt; The _event_timeout_remove and _event_handle_remove methods were holding onto the global lock when invoking the free callback. This is a violation of the libvirt events API contract which requires free callbacks to be invoked in a re-entrant safe context. --- libvirt-glib/libvirt-glib-event.c | 8 ++------ 1 file changed, 2 insertions(+), 6 deletions(-) diff --git a/libvirt-glib/libvirt-glib-event.c b/libvirt-glib/libvirt-glib-event.c index 657c1bf..2a9ee23 100644 --- a/libvirt-glib/libvirt-glib-event.c +++ b/libvirt-glib/libvirt-glib-event.c @@ -256,13 +256,11 @@ _event_handle_remove(gpointer data) { struct gvir_event_handle *h = data; - g_mutex_lock(eventlock); - if (h->ff) (h->ff)(h->opaque); + g_mutex_lock(eventlock); g_ptr_array_remove_fast(handles, h); - g_mutex_unlock(eventlock); return FALSE; @@ -414,13 +412,11 @@ _event_timeout_remove(gpointer data) { struct gvir_event_timeout *t = data; - g_mutex_lock(eventlock); - if (t->ff) (t->ff)(t->opaque); + g_mutex_lock(eventlock); g_ptr_array_remove_fast(timeouts, t); - g_mutex_unlock(eventlock); return FALSE; -- 1.7.11.2
