2019-08-09tls: mark as no lookup transportFlorin Coras1-1/+1
Type:fix Also fix transport close while handshake is ongoing. Change-Id: I004c56d2297d0847c2cb77202f8fba3edaacad29 Signed-off-by: Florin Coras <fcoras@cisco.com>
2019-08-08udp: fix connections moveAloys Augustin1-0/+28
Without this the use of uc0 is racy between the current thread and the thread that owns it and will delete it. This also ensures we don't trigger a read event on the session before moving it to the right thread and notifying the application.

2019-07-15session: allow transports to generate closed notificationsFlorin Coras1-26/+27
In contrast to the closing notification, whereby a transport informs the session layer that is beginning the closing procedure, this allows transports to notify the session layer of the fact that the transport is "fully" closed, i.e., it expects no more data. Also: - adds app closed state for sessions - changes tcp to have it notify when an active close has finished Type: feature Change-Id: I13c738006c03f85015e05ab82843a33a69382aaf Signed-off-by: Florin Coras <fcoras@cisco.com>

Add SESSION_IO_EVT_RX handling in session_send_evt_to_thread to allow internal apps to send rx events ("tx notifications") to quic. Add a call to quic_send_packets in quic_custom_app_rx_callback to ensure QUIC ACKs are sent if there is no other activity on the connection.

2019-04-16svm_fifo rework to avoid contention on cursizeSirshak Das1-3/+3
Problems Addressed: - Contention of cursize by producer and consumer. - Reduce the no of modulo operations. Changes: - Synchronization between producer and consumer changed from cursize to head and tail indexes Implications: reduces the usable size of fifo by 1. - Using weaker memory ordering C++11 atomics to access head and tail based on producer and consumer role. - Head and tail indexes are unsigned 32 bit integers. Additions and subtraction on them are implicit 32 bit Modulo operation. - Adding weaker memory ordering variants of max_enq, max_deq, is_empty and is_full Using them appropriately in all places. Perfomance improvement (iperf3 via Hoststack): iperf3 Server: Marvell ThunderX2(AArch64) - iperf3 Client: Skylake(x86) ~6%(256 rxd/txd) - ~11%(2048 rxd/txd) Change-Id: I1d484e000e437430fdd5a819657d1c6b62443018 Signed-off-by: Sirshak Das <sirshak.das@arm.com> Reviewed-by: Honnappa Nagarahalli <honnappa.nagarahalli@arm.com>
