2020-03-03l4p/tcp_ofo: Add usage of --mbuf-numMariusz Drost1-2/+5
Addition of --mbuf-num cmd-line parameter usage in ofo/loss tests. Value is lower that default to meet CI environment capabilities. Additionally fixed issue when test script in tap mode tries to create temporary result file on remote machine.

2020-03-03l4fwd: Add new cmd-line parameter --mbuf-numMariusz Drost5-9/+21
In some cases default value of MPOOL_NB_BUF is too large. Because of that new cmd-line parameter is added (--mbuf-num/-M), so user can define that value directly before running an application. Introduced parameter is optional. Default value of MPOOL_NB_BUF (0x20000) is preserved. Signed-off-by: Mariusz Drost <mariuszx.drost@intel.com> Change-Id: I9517955f313b6e97da1bb20c50b25e761430e0a8
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.

2019-12-31v6: make TCP stream alloc/free to use memtank APIKonstantin Ananyev15-69/+197
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: memtank introductionKonstantin Ananyev10-0/+2295
For analogy with mempool, named this structure memtank. Same a s mempool it allows to alloc/free objects of fixed size in a lightweight manner (not as lightweight as mempool, but hopefully close enough). The whole idea is that alloc/free is used at fast-path and don't allocate/free more than *min_free* objects at one call. So for majority of cases our fast-path alloc/free should be lightweight (LIFO enqueue/dequeue operations). Also user will need to call grow/shrink periodically (ideally from the slow-path) to make sure there is enough free objects in the tank. Internally it is just a simple LIFO for up to *max_free* objects plus a list of memory buffers (memchunk) from where these objects were allocated. v1 -> v2 - Added UT - Fixed few bugs v2 -> v3 - extend UT with more parameters v3 -> v4 - add object alignement as parameter for memtank_create - extend UT with more parameters - added memtank dump routine v4 -> v5 - fixed few bugs inside memtank lib - extend UT with: - new test case - new command-line options: '-s <obj_size>', '-m <mem_func>' v5 -> v6 - extend memtank dump to collect/display extra information - make memtank dump routine MT safe - add memtank sanity check function - add proper comments for pubic API Signed-off-by: Konstantin Ananyev <konstantin.ananyev@intel.com> Change-Id: I8939772577f5d9e293088eaa9a9fe316c3fe8f87
2019-12-19l4p/tcp_ofo: fix killing l4fwd app in testsMariusz Drost1-1/+1

2019-10-09l4p/tcp: fix SIGSEGV when reading IPv6 addressMariusz Drost1-1/+1
IPv6 address is obtained through pointer to mbuf (part storing IPv6 addr). Structure which then holds that pointer defines it as a pointer to _m128i data type. Because of that, when code is optimized, instruction vmovdqa is used, which requires data to be aligned to 16-bytes. Pointer from mbuf does not have to be aligned in that way, which may cause SIGSEGV. Solution is to add attribute packed and aligned(1) to structure holding IPv6 address. With that, vmovdqu assembly instruction is used, which is the equivalent of vmovdqa, but for unaligned data.

2019-08-13l4p/tcp_ofo: fix handling out-of-order packetsJielong Zhou3-69/+128
Problems are: 1. ofodb could not be assigned directly, as direct assignment does not copy the mbuf pointer area belonging to it. 2. _ofo_insert_new and _ofo_insert_right doesn't remove overlap correctly. 3. _ofo_insert_new insert new db in wrong position. 4. rx_ofo_reduce sets wrong seq, and would insert overlapped data into rx queue. 5. _ofo_compact may miss compacting some ofodbs and doesn't update partly moved ofodb correctly.

Created a clone of nginx (from https://github.com/nginx/nginx) to demonstrate and benchmark TLDK library integrated with real world application. A new nginx module is created and and BSD socket-like API is implemented on top of native TLDK API. Note, that right now only minimalistic subset of socket-like API is provided: - accept - close - readv - recv - writev so only limited nginx functionality is available for a moment.
