2021-12-16session: app mq congestion detectionFlorin Coras1-42/+283
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 Coras1-2/+5
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 Coras1-43/+14
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 Coras1-61/+13
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.

2019-07-15session: allow transports to generate closed notificationsFlorin Coras1-0/+9
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>

2019-04-16svm_fifo rework to avoid contention on cursizeSirshak Das1-14/+5
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.
