2020-11-09vlib: fix trace number accountingBenoît Ganne1-11/+15
When using classifier to filter traces, not all packets will be traced. In that case, we should only count traced packets. Type: fix Change-Id: I87d1e217b580ebff8c6ade7860eb43950420ae78 Signed-off-by: Benoît Ganne <bganne@cisco.com>

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.

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.

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.

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>
