2019-07-29session: fix vpp to app msg generationFlorin Coras1-60/+25
Type:fix Freeing mq messages in vpp (producer), if enqueueing fails, invalidates consumer assumption that messages can be freed without a lock. Change-Id: I748a33b8846597bdad865945d8e899346d482434 Signed-off-by: Florin Coras <fcoras@cisco.com> Signed-off-by: Tal Saiag <tal.saiag@gmail.com>
2019-07-15session: allow transports to generate closed notificationsFlorin Coras1-0/+9
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 Das1-14/+5
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>

2019-03-06session: use vpp to switch io events for ct sessionsFlorin Coras1-3/+2
