Type: improvement - allow apps to request rescheduling of tx events via SESSION_F_CUSTOM_TX flag - limit max burst per session custom tx dispatch In tls - use the new infra to reschedule tx events - use max burst bytes as upper limit to number of bytes to be encrypted Signed-off-by: Florin Coras <fcoras@cisco.com> Change-Id: I544a5a3337af7ebdff3406b776adf30cf96ebf3c

2020-03-19session tcp udp: consolidate transport snd apisFlorin Coras1-37/+39
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

2019-11-20session tcp: support pacer idle timeoutsFlorin Coras1-3/+16
Type: feature To avoid excessive bursts, pacer must be provided with an estimated rtt for the connection. That's used to compute an idle timeout, i.e., time after which the bucket is reset to 1 mtu due to inactivity. For now, idle timeout is computed as 5% of the rtt. Change-Id: Ia0b752fe7b4ad0ce97b477fb886b0133a2321541 Signed-off-by: Florin Coras <fcoras@cisco.com>

2019-10-17session: unify buffer tx dispatchingFlorin Coras1-26/+11
Type: refactor Use pending tx buffer vector to postpone dispatching of all buffers, i.e., either generated as a result of tx events or custom tx event. Change-Id: Ic5894c4653c338cfb04555d20857f954b245ee83 Signed-off-by: Florin Coras <fcoras@cisco.com>
2019-10-17session tcp: infra for transports to send buffersFlorin Coras1-0/+14
Type: feature Add infra that allows transpors to enqueue pending buffers without the need to build and manage their own pending frames. An important benefit is the fact that buffer wire/tx ordering is ensured by session layer. Change-Id: I764fd1693d610b321a1d0c84b648a314f14583db Signed-off-by: Florin Coras <fcoras@cisco.com>

2019-10-09session: Add certificate storeNathan Skrzypczak1-1/+3
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 Coras1-53/+319
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. Change-Id: I93f6d18e551b024effa75d47f5ff25f23ba8aff5 Signed-off-by: Florin Coras <fcoras@cisco.com>
2019-08-19session: add explicit reset apiFlorin Coras1-0/+6
Type: feature This can be used to forcefully close a session. It's only available to builtin applications for now. Transports must support the reset api otherwise normal close is used. Change-Id: I5e6d681cbc4c8045385e293e0e9d86fa2bf45849 Signed-off-by: Florin Coras <fcoras@cisco.com>
2019-08-09session: allow closed transports to sendFlorin Coras1-4/+16
Type:fix Transports like tcp may notify session layer of a close but they may defer the connection's deletion (e.g., tcp time-wait). During that time, transports may still want to send packets. So, unless the session has no transport (transport-deleted state), allow the transport to send. Change-Id: I3ae335c7b951ff64be8529a5e3f3ad790feddc84 Signed-off-by: Florin Coras <fcoras@cisco.com>
2019-08-05session: cache align transport base classFlorin Coras1-1/+1
Type:refactor Also remove tx stats. Expectation is that transports will keep track of them. Change-Id: I083b328d87d0ad3688b630ddb5ef97827a4dbc2b Signed-off-by: Florin Coras <fcoras@cisco.com>
2019-07-29session: fix vpp to app msg generationFlorin Coras1-6/+3
Type:fix Freeing mq messages in vpp (producer), if enqueueing fails, invalidates consumer assumption that messages can be freed without a lock. Change-Id: I748a33b8846597bdad865945d8e899346d482434 Signed-off-by: Florin Coras <fcoras@cisco.com> Signed-off-by: Tal Saiag <tal.saiag@gmail.com>
