2020-02-04l4p/tcp_ofo: ofo and loss tests mergeMariusz Drost4-166/+315
Addition of tests for packets that are out of order or lost that are executed on a single machine (with use of tap interface). Added tests are merged into existing test suite which runs on local/remote machine. Choice of mode is done with ETH_DEV variable.

2020-02-03l4fwd: Change rx offload defaultMariusz Drost1-5/+1
Tap interface does not provide any offload capabilities. To use that interface with l4fwd app, default offload capabilities should be set to 0. Signed-off-by: Mariusz Drost <mariuszx.drost@intel.com> Change-Id: If30f44bb986b87e079be3ec1dfe0ad5341862030
2019-12-31v6: make TCP stream alloc/free to use memtank APIKonstantin Ananyev1-0/+1
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.

2019-12-19l4p/tcp_ofo: fix killing l4fwd app in testsMariusz Drost1-1/+1
Between test cases l4fwd application is closed with kill command. Default kill signal is SIGTERM which is not supported in l4fwd. To close l4fwd cleanly, signal has been changed to SIGINT. Signed-off-by: Mariusz Drost <mariuszx.drost@intel.com> Change-Id: If083f18cab22766154cc80afa26d45d953277294
2019-12-12l4p/tcp_ofo: Tests for ofo and loss of pktsMariusz Drost4-0/+1098
Tests for packets that are out of order and lost. They validate data send over netcat (TCP) to TLDK/l4fwd app in echo mode. Data is set to be reordered or loss some percentage of packets. Signed-off-by: Mariusz Drost <mariuszx.drost@intel.com> Change-Id: I68f80d1fb75d5e9e5ed6d052ddcdc60588284f78

DPDK v18.11 is the latest LTS verison. As of the API/ABI changes introduced in ether at v18.08, we cannot compile l4fwd and nginx with old DPDK versions.

- 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.

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 Ananyev23-2930/+4742
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.

2016-09-06Initial working version of RSSMohammad Abdul Awal7-309/+738
The patch enables RSS support for TLDK udpfwd application. The number of rx queues and tx queues are equal to the number of lcore enabled for backend operation. NICs calculate the RSS hash based on the UDP dest port only. The RSS hash key is calculated at runtime based on the number of queues enebaled.
