2020-03-19session tcp udp: consolidate transport snd apisFlorin Coras1-0/+13
Type: improvement Use only one api to retrieve transport send parameters. Additionally, allow transports to request postponing and descheduling of events. With this, tcp now requests descheduling of sessions when the connections are stuck probing for zero snd_wnd Signed-off-by: Florin Coras <fcoras@cisco.com> Change-Id: I722c974f3e68fa15424c519a1fffacda43af050c

2019-08-27session: move ctrl messages from bapi to mqFlorin Coras1-4/+4
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.

2019-08-08udp: fix connections moveAloys Augustin1-0/+28
Without this the use of uc0 is racy between the current thread and the thread that owns it and will delete it. This also ensures we don't trigger a read event on the session before moving it to the right thread and notifying the application.

Type: fix Change the sequence to first allocate session_manager and then enable the session-nodes.

2019-07-15session: allow transports to generate closed notificationsFlorin Coras1-26/+27
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>

Add SESSION_IO_EVT_RX handling in session_send_evt_to_thread to allow internal apps to send rx events ("tx notifications") to quic. Add a call to quic_send_packets in quic_custom_app_rx_callback to ensure QUIC ACKs are sent if there is no other activity on the connection.
