2021-06-03l4p: add ability to assign user-data to the streamKonstantin Ananyev1-0/+2
Add ability for the user to assign user provided data to the stream. Right now this user provided 64-bit value is passed as a parameter for lookup4/lookup6 callbacks. Another change: change interpretation of lookup4()/lookup6() return value: < 0: error code (existing behaviour). == 0: success, TLDK will update L3 header src/dst addresses based on tldk dev values (existing behaviour). > 0: success, TLDK will not update L3 header src/dst addresses, will rely on user provided values.

2021-05-14l4p/tcp: introduce tle_tcp_stream_rx_bulk() APIKonstantin Ananyev1-0/+34
tle_tcp_stream_rx_bulk() allows to push input packets for futher processing straight into given TCP stream. Given stream is expected to be already in connected state. Signed-off-by: Konstantin Ananyev <konstantin.ananyev@intel.com> Change-Id: I94a744d6d9c8ff3671ebfa84b83a34a24612bde0
2021-05-14l4p/tcp: introduce tle_tcp_stream_establish() APIKonstantin Ananyev1-0/+32
tle_tcp_stream_establish() allows to create streams in established connection state. Signed-off-by: Konstantin Ananyev <konstantin.ananyev@intel.com> Change-Id: Ib302c4d7f229144d2624279f973f00041fb611b2
2017-07-27- Introduce tle_tcp_stream_readv() and tle_tcp_stream_writev().Konstantin Ananyev1-12/+60
- Introduce flags for tle_ctx_param. - Introduce TLE_CTX_FLAG_ST - indicates that given ctx will be used by single thread only. - Introduce new parameters for tcp context: timewait - allows user to configure max timeout in TCP_TIMEWAIT state. icw - allows user to specify desired initial congestion window for new connections. -Few optimisations: cache tx.ol_flags inside tle destination. calcualte and cache inside ctx cycles_to_ms shift value. reorder restoring SYN opts and filling TCB a bit.

2017-06-30Add l4fwd RXTX modeRemy Horton1-0/+10
This mode allows for transactions where the request and response are of different payload sizes Change-Id: I0744159f0618c9241e576a4af1c02765bbf1dd9f Signed-off-by: Remy Horton <remy.horton@intel.com>
2017-03-06Rewrite accept() code-path and make l4fwd not to close() on FIN immediatelly.Konstantin Ananyev1-65/+39
Changes in public API: - removes tle_tcp_stream_synreqs() and tle_tcp_reject() - adds tle_tcp_stream_update_cfg Allocates and fills new stream when final ACK for 3-way handshake is received. Changes in l4fwd sample application: prevents l4fwd to call close() on error event immediately: first try to recv/send remaining data.

2017-02-24Introduce first version of TCP code.Konstantin Ananyev1-0/+395
Supported functionality: - open/close - listen/accept/connect - send/recv In order to achieve that libtle_udp library was reworked into libtle_l4p library that supports both TCP and UDP protocols. New libtle_timer library was introduced (thanks to Cisco guys and Dave Barach <dbarach@cisco.com> for sharing their timer code with us). Sample application was also reworked significantly to support both TCP and UDP traffic handling. New UT were introduced.
