Revision 3cec638b3d793b7cacdec5b8072364b41caeb0e1 authored by Steven Rostedt (VMware) on 10 December 2018, 02:17:30 UTC, committed by Steven Rostedt (VMware) on 11 December 2018, 18:50:19 UTC
When create_event_filter() fails in set_trigger_filter(), the filter may
still be allocated and needs to be freed. The caller expects the
data->filter to be updated with the new filter, even if the new filter
failed (we could add an error message by setting set_str parameter of
create_event_filter(), but that's another update).
But because the error would just exit, filter was left hanging and
nothing could free it.
Found by kmemleak detector.
