RX buffer allocation has been reworked in current dev tree. The objective is to support multiple buffers per QCS to improve upload throughput. RX buffer allocation failure is handled simply : the whole connection is closed. This is done via qcc_set_error(), with INTERNAL_ERROR as error code. This function contains a BUG_ON() to ensure it is called only one time per connection instance. On RX buffer alloc failure, the aformentioned BUG_ON() crashes due to a double invokation of qcc_set_error(). First by qcs_get_rxbuf(), and immediately after it by qcc_recv(), which is the caller of the previous one. This regression was introduced by the following commit. 60f64449fbba7bb6e351e8343741bb3c960a2e6d MAJOR: mux-quic: support multiple QCS RX buffers To fix this, simply remove qcc_set_error() invocation in qcs_get_rxbuf(). On buffer alloc failture, qcc_recv() is responsible to set the error. This does not need to be backported.
