2019-07-16session: fix node enable sequenceVladimir Kropylev1-1/+1
Type: fix Change the sequence to first allocate session_manager and then enable the session-nodes. During “session enable”, sometimes an issue was seen when in some cases POLLING node calls transport_update_time -> tcp_update_time -> tcp_set_time_now which access tcp_main.wrk_ctx before tcp_main_enable allocates the wrk_ctx. 0 0x00007ffff73f7778 in tcp_set_time_now (wrk=<optimized out>) at src/vnet/tcp/tcp.h:953 1 tcp_update_time (now=11.059735140000001, thread_index=<optimized out>) at src/vnet/tcp/tcp.c:1192 2 0x00007ffff75a75de in transport_update_time (time_now=11.059735140000001, thread_index=thread_index@entry=1 '\001') at src/vnet/session/transport.c:740 3 0x00007ffff75a0f4c in session_queue_node_fn (vm=0x7fff74913480, node=0x7fff75e7d5c0, frame=<optimized out>) at src/vnet/session/session_node.c:873 Change-Id: Id2288dd05ba179af2ff22c58bac1331fc21a1c7d Signed-off-by: Vladimir Kropylev <vladimir.kropylev@enea.com>
2019-07-15session: allow transports to generate closed notificationsFlorin Coras5-27/+42
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>

2019-04-16svm_fifo rework to avoid contention on cursizeSirshak Das5-25/+18
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>

To connect a stream, apps should call connect while passing the id of the QUIC connection in the new transport_opts field in session_endpoint_cfg_t. Apps are notified of new streams with their accept callback, which is called each time a peer opens a stream.
