Under some circumstances (such as terminating bluetoothd during music is streamed) sep object may be destroyed (memory for sep object is internally freed, directly by "a2dp_unregister_sep") after invoking "media_endpoint_clear_configuration" (in "stream_state_changed"). It leads to invalid write issue (reported by valgrind) after assignment "sep->stream = NULL", since "sep" is "alias" pointer to sep object which is already out of date (memory for sep object has been already freed) This patch prevents from this issue by ensuring that assignment "sep->stream = NULL" would be executed when sep object certainly exists. --- audio/a2dp.c | 5 ++--- 1 files changed, 2 insertions(+), 3 deletions(-) diff --git a/audio/a2dp.c b/audio/a2dp.c index b4ec274..f3e7af3 100644 --- a/audio/a2dp.c +++ b/audio/a2dp.c @@ -371,11 +371,10 @@ static void stream_state_changed(struct avdtp_stream *stream, sep->session = NULL; } - if (sep->endpoint) - media_endpoint_clear_configuration(sep->endpoint); - sep->stream = NULL; + if (sep->endpoint) + media_endpoint_clear_configuration(sep->endpoint); } static gboolean auto_config(gpointer data) -- 1.6.3.3 -- To unsubscribe from this list: send the line "unsubscribe linux-bluetooth" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
