2021-05-13l4p/tcp: introduce tle_tcp_stream_establish() APIKonstantin Ananyev1-5/+9
tle_tcp_stream_establish() allows to create streams in established connection state. Signed-off-by: Konstantin Ananyev <konstantin.ananyev@intel.com> Change-Id: Ib302c4d7f229144d2624279f973f00041fb611b2
2019-12-31v6: make TCP stream alloc/free to use memtank APIKonstantin Ananyev1-1/+3
Introduce two extra parameters for TCP context creation: struct { uint32_t min; /**< min number of free streams (grow threshold). */ uint32_t max; /**< max number of free streams (shrink threshold). */ } free_streams; By default these params are equal to max_streams value (avoid dynamic allocation and preserve current beahviour). grow() is invoked from accept() FE call to refill streams tank for BE. shrink() is invoked from close() FE call.

2019-12-31v6 rework TCP stream allocationKonstantin Ananyev1-0/+23
Allocate TCP stream and all necessary metadata (RX/TX queues, OFO queue, DRBs, etc.) as one big buffer, instead of separate alloc() calls for each of the sub-components. Signed-off-by: Konstantin Ananyev <konstantin.ananyev@intel.com> Change-Id: Idc9f3e9329920dfb34916f9bff28664ee5e99a42
2017-07-27- Introduce tle_tcp_stream_readv() and tle_tcp_stream_writev().Konstantin Ananyev1-4/+5
- 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.

2017-02-24Introduce first version of TCP code.Konstantin Ananyev1-0/+170
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.
