2023-12-22quic: seed random generator during initFilip Tehlar1-0/+8
Quic does not seed random value, so if the plugin is loaded separately RAND_bytes will fail. Type: fix Change-Id: If600cbde1fef30afb6316fc1a355261b008c3191 Signed-off-by: Filip Tehlar <ftehlar@cisco.com>
2023-09-13quic: fix quic sessions state updatesFlorin Coras1-11/+5
Session state cannot be updated after async notification event is generated for app. Instead, make sure quic sessions that accept new streams are switched to listening state only on accept.

2023-09-04session: fix allocation of proxy fifosFlorin Coras1-0/+1
Fifos need to be synchronously allocated once a transport like tcp accepts a session. Since events are now delivered asynchronously, proxy apps must explicitly register a cb function that manages fifo allocation prior to being notified of connect event.

2023-08-09session: async rx event notificationsFlorin Coras1-5/+2
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.

2021-08-03quic: do not update crypto keys from workersAloys Augustin1-2/+7
The vnet_crypto_key_add should only be called from the main thread. This patch works around this limitation by allocating one key per worker and updating it on the fly everytime we need to do a crypto operation. This solution is far from ideal, but quicly has a strong assumption that it can use a key immediately after determining it, so making the key creation asynchronous is not a possibility.

2021-05-07session: connects seg manager is always firstFlorin Coras1-3/+0
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.

2020-02-25svm: refactor fifoFlorin Coras1-17/+2
Type: refactor Switch from a wrapped byte space to a "continuous" one wherein fifo chunks are appended to the fifo as more data is enqueued and chunks are removed as data is dequeued. The fifo is still subject to a maximum size, i.e., maximum number of bytes that can be enqueued, so the max number of chunks associated to the fifo is also constrained. When enqueueing data, which must fit within the available free space, if not enough "supporting" chunk memory is available, the fifo asks the fifo segment for enough chunk memory to ensure that the write can succeed. To avoid allocating large amounts of small chunks due to small writes, if possible, the size of the chunks requested is lower capped by min_alloc. When dequeuing data, all the chunks that have been completely drained, i.e., head moved beyond the chunks’ end bytes, are unlinked from the fifo and returned to the fifo segment. The one exception to this is the last chunk which is never unlinked. Change-Id: I98c1dbd9135fb79650365c7e40c29238b96cd4ee Signed-off-by: Florin Coras <fcoras@cisco.com>
