2019-11-12vcl: fix nonblocking accept with >1 event in the queueCarl Smith1-3/+3
We discard unwanted events until we get an ACCEPTED. But if we are non-blocking we need to check the queue length every time and EAGAIN if empty before waiting. Type: fix Signed-off-by: Carl Smith <carl.smith@alliedtelesis.co.nz> Change-Id: Ie0c7e5cb00f0d37d2e1534f8bb384221ff56f2e3

2019-08-27session: move ctrl messages from bapi to mqFlorin Coras1-18/+106
Type:refactor Moves connect, disconnect, bind, unbind and app detach to message queue from binary api. Simplifies app/vcl interaction with the session layer since all session control messages are now handled over the mq. Add/del segment messages require internal C api changes which affect all builtin applications. They'll be moved in a different patch and might not be back portable to 19.08.

Type: feature * Adds the concept of a "connectable listener" : a session that can be both connected and accepted on. * vppcom_session_is_connectable_listener (fd) that tells if the fd is a connectable listener * vppcom_session_listener (fd) that gives you the listener's fd that accepted the session (if any) * vppcom_session_n_accepted (fd) that gives the number of sessions a listener accepted.

2019-04-16svm_fifo rework to avoid contention on cursizeSirshak Das1-8/+9
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>

2019-01-30vls: support passive listenersFlorin Coras1-3/+11
If an application worker calls listen on a session, vpp registers the worker to the listener's work load balance group and, as new connections are accepted, it may potentially push accept notifications to it. There are however applications, like nginx, that on some workers may never accept new connections on a session they've started listening on. To avoid accumulating accept events on such workers, this patch adds support for passive listeners. That is, workers that have started listening on a session but then never call accept or epoll/select on that listener.
