2024-01-09session: make app listener pool globalFlorin Coras1-5/+4
One less pointer chase when accepting sessions. Type: improvement Signed-off-by: Florin Coras <fcoras@cisco.com> Change-Id: I20dbb21d15d4a703f76e3b12f04a6f5b5d2a3cd8
2024-01-09session: support for cl port reuseFlorin Coras1-0/+5
Adds support for connectionless listener port reuse. Until now, cl listeners had fifos allocated to them and therefore only one app worker could ever listen, i.e., a session cannot have multiple fifos. To circumvent the limitation, this separates the fifos from the listener by allocating new cl sessions for each app worker that reuses the app listener. Flows are hashed to app worker cl sessions but, for now, this is not a consistent/fixed hash.

2023-08-09session: async rx event notificationsFlorin Coras1-11/+36
Move from synchronous flushing of io and ctrl events from transports to applications to an async model via a new session_input input node that runs in interrupt mode. Events are coalesced per application worker. On the one hand, this helps by minimizing message queue locking churn. And on the other, it opens the possibility for further optimizations of event message generation, obviates need for rx rescheduling rpcs and is a first step towards a fully async data/io rx path.

Detect mq congestion and handle it by queueing messages in a fifo and postponing handling via rpcs. App workers with congested mqs cannot accept nor connect additional sessions. Type: feature Signed-off-by: Florin Coras <fcoras@cisco.com> Change-Id: I401d971a1a53896758b88fc60f158cbc31e0c7cb

2021-05-12tls: switch to vc service and track half-open sessionsFlorin Coras1-1/+1
Half-open tls sessions are now tracked by the app worker and are cleaned up only when tcp cleans up its half-open session, i.e., independent of when the established tls context is allocated.

2021-05-10session: use half-open sessions for vc establishmentFlorin Coras1-9/+4
Use half-open sessions to track virtual circuit connection establishment. These sesssions can only be allocated and freed by the thread that allocates half-open connections (main). Consequently, they can only be freed on half-open cleanup notifications from transports. Goal is to simplify state tracking within the session layer but it's also a first step towards allowing builtin apps to track and cleanup outstanding connects.

2021-05-07session: connects seg manager is always firstFlorin Coras1-12/+6
By convention, connects segment manager will be first. Therefore it will be the one with the first segment wherein lies the app's message queue. Saves us the trouble of allocating it on first connect, if app started by listening, and we no longer need to track if it's assignable to a listener or if it can be removed.

2021-03-29svm session vcl: per app rx message queuesFlorin Coras1-0/+56
Add option to use per app private segments for app to vpp message queues, as opposed to exposing internal message queues segment. When so configured, internal message queues are still polled by the session queue node but external app message queues are handled by a new input node (appsl-rx-mqs-input) that runs in interrupt state. Signaling of the node, when mqs receive new messages, is done through eventfds epolled by worker epoll input nodes.

2019-12-17quic: Implement crypto contextsNathan Skrzypczak1-1/+0
Type: feature Make quic use the crypto contexts. This introduces a crypto context pool backed by a hashtable giving ctx indexes by connect params (ckpair, engine, rx & tx fifo sizes). Applications keep the initialization vector common. Change-Id: I22ed6711196cd70a2f2f74240f12113c7af8dfcd Signed-off-by: Nathan Skrzypczak <nathan.skrzypczak@gmail.com>

2019-10-09session: Add certificate storeNathan Skrzypczak1-10/+8
Type: feature This changes the behavior of both API calls APPLICATION_TLS_CERT_ADD & APPLICATION_TLS_KEY_ADD certificates and keys aren't bound to an app, they are passed to it via connect / listen using the message queue. This should be followed by a per protocol (QUIC/TLS) crypto_context store to save devrived structs Change-Id: I36873bc8b63b5c72776c69e8cd9febc9cae31882 Signed-off-by: Nathan Skrzypczak <nathan.skrzypczak@gmail.com>
2019-08-27session: move ctrl messages from bapi to mqFlorin Coras1-0/+9
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.

2019-07-15session: allow transports to generate closed notificationsFlorin Coras1-0/+2
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>
