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.

session_pool_add_peeker()

static void session_pool_add_peeker ( u32  thread_index )

inlinestatic

Acquires a lock that blocks a session pool from expanding.

This is typically used for safely peeking into other threads' pools in order to clone elements. Lock should be dropped as soon as possible by calling session_pool_remove_peeker.

NOTE: Avoid using pool_elt_at_index while the lock is held because it may lead to free elt bitmap expansion/contraction!

Notification from transport that it is closed.

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.

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).
