session_open()

int session_open	(	u32	app_wrk_index,

Ask transport to open connection to remote transport endpoint.

Stores handle for matching request with reply since the call can be asynchronous. For instance, for TCP the 3-way handshake must complete before reply comes. Session is only created once connection is established.

Parameters

app_index	Index of the application requesting the connect
st	Session type requested.
tep	Remote transport endpoint
opaque	Opaque data (typically, api_context) the application expects on open completion.

Should be called by transport, prior to calling delete notify, once it knows that no more data will be exchanged. This could serve as an early acknowledgment of an active close especially if transport delete can be delayed a long time, e.g., tcp time-wait.

(

transport_connection_t *

tc

)

Notification from transport that connection is being closed.

A disconnect is sent to application but state is not removed. Once disconnect is acknowledged by application, session disconnect is called. Ultimately this leads to close being called on transport (passive close).

(

tc

Notification from transport that connection is being deleted.

This removes the session if it is still valid. It should be called only on previously fully established sessions. For instance failed connects should call stream_session_connect_notify and indicate that the connect has failed.

(

Allocate event queues in the shared-memory segment.

That can either be a newly created memfd segment, that will need to be mapped by all stack users, or the binary api's svm region. The latter is assumed to be already mapped. NOTE that this assumption DOES NOT hold if api clients bootstrap shm api over sockets (i.e. use memfd segments) and vpp uses api svm region for event queues.
