To enable add "app-socket-api /path/to/socket" to vcl.conf. On vpp side, add use-app-socket-api to session stanza in startup.conf VPP allocates a socket per application namespace which it places in the app_ns_sockets subfolder of the run folder (default /var/run/vpp). The socket used implicitly selects the app namespace for the vcl app. Type: feature Signed-off-by: Florin Coras <fcoras@cisco.com> Change-Id: Ifc14b93dcbf6ef9bed1852d46cd069f4855b92ef

2020-08-12vcl: support multi-threads with session migrationhanlin1-5/+8
Currently, mutlti-threads only support one dispatch thread and multiple worker threads, eventually only dispatch thread is a vcl worker and can interact with epoll. This patch will register all threads as vcl worker, and then each thread can interact with epoll now. Moreover, session migration also supported, such as socket created in thread A and used (bind, connect and etc.) in thread B.

2020-05-14vcl svm: fix rx event losshanlin1-2/+5
When vcl_epoll_wait_handle_mq handles rx events exceeding maxevents, VPP will not signal because cursize > 0, and the remaining rx events cannot be triggered because the eventfd event has been read. Therefore, we should dequeue all events until cursize = 0. And then handle msg up to maxevents with vcl_epoll_wait_handle_mq_event and those beyond with vcl_handle_mq_event.

2020-05-04vcl: allow vcl worker index to be set by applicationsPivo1-0/+6
When using vppcom_session* apis to setup TCP sessions in applications build outside of the VPP repository, it is necessary to set the worker_index explicitly when these apis are called from the none-VCL worker threads. An example is when data is to be sent to the TCP session that is originated from a different thread, like the main program thread or from the bin api thread. This change allows the application to set it. Type: fix Signed-off-by: IJsbrand Wijnands <ice@cisco.com> Change-Id: I37f3654a49ea9a8cf3a0d3d0e672583018c12299
