This library is suggested to provide a helper API to convert packet based information to the flow records. Basically the library consist of APIs to validate, create and destroy the rule and to query the stats. Application should call the query API for all received packets. The library header file has more comments on how library works and provided APIs. Packets to flow conversion will cause performance drop, that is why conversion done on demand by an API call provided by this library. The initial implementation is to provide counting of IPv4 five tuple packets for UDP, TCP and SCTP but the library is planned to be as generic as possible. The flow information provided by this library is missing to implement full IPFIX features, but this is planned to be initial step. Flows are defined using rte_flow, also measurements (actions) are provided by rte_flow. To support more IPFIX measurements, the implementation may require extending rte_flow in addition to extending this library. The library uses both flows and actions defined by rte_flow.h so this library has a dependency on rte_flow.h. For further steps, this library can be expanded to benefit from hardware filters for better performance. It will be more beneficial to shape this library to cover more use cases, please feel free to comment on possible other use cases and desired functionalities. Changes in v7: Fix rte_flow_classify_version.map file. Fix checkpatch warnings. Changes in v6: Dropped two librte_table patches (patches 1 and 2 in v5 patch set). Revised librte_flow_classify patch to use librte_table API's correctly. Changes in v5: Added tests for TCP an STCP traffic to unit test code. Added patch to packet_burst_generator code to add functions for TCP and SCTP protocols. Changes in v4: Replaced GET_CB_FIELD macro with get_cb_field function in the flow classify sample application to fix checkpatch warning. Fixed checkpatch warnings in test_flow_classify.c Changes in v3: Patch 3 from the v2 patch set has been dropped,"librte_ether: initialise IPv4 protocol mask for rte_flow". The flow_classify sample application is now using an input file of IPv4 five tuple rules instead of hardcoded values. A minor fix to the rte_flow_classify_create() function. Changes in v2: Patch 1, librte_table: move structure to header file, has been dropped. The code has been reworked to not access struct rte_table_acl directly. An entry_size parameter has been added to the rte_flow_classify_create function. The f_lookup function is now called instead of the rte_acl_classify function. Patch 2, librte_table: fix acl lookup function, has been added. Changes in v1, since RFC v3: added rte_flow_classify_validate API. librte_table ACL is used for packet matching. a table_acl parameter has been added to all of the API's an error parameter has been been added to all of the API's Bernard Iremonger (3): examples/flow_classify: flow classify sample application test: add packet burst generator functions test: flow classify library unit tests Ferruh Yigit (1): librte_flow_classify: add librte_flow_classify library MAINTAINERS | 7 + config/common_base | 6 + doc/api/doxy-api-index.md | 1 + doc/api/doxy-api.conf | 1 + examples/flow_classify/Makefile | 57 ++ examples/flow_classify/flow_classify.c | 897 +++++++++++++++++++++ examples/flow_classify/ipv4_rules_file.txt | 14 + lib/Makefile | 3 + lib/librte_eal/common/include/rte_log.h | 1 + lib/librte_flow_classify/Makefile | 51 ++ lib/librte_flow_classify/rte_flow_classify.c | 460 +++++++++++ lib/librte_flow_classify/rte_flow_classify.h | 207 +++++ lib/librte_flow_classify/rte_flow_classify_parse.c | 546 +++++++++++++ lib/librte_flow_classify/rte_flow_classify_parse.h | 74 ++ .../rte_flow_classify_version.map | 10 + mk/rte.app.mk | 2 +- test/test/Makefile | 1 + test/test/packet_burst_generator.c | 191 +++++ test/test/packet_burst_generator.h | 22 +- test/test/test_flow_classify.c | 698 ++++++++++++++++ test/test/test_flow_classify.h | 240 ++++++ 21 files changed, 3486 insertions(+), 3 deletions(-) create mode 100644 examples/flow_classify/Makefile create mode 100644 examples/flow_classify/flow_classify.c create mode 100644 examples/flow_classify/ipv4_rules_file.txt create mode 100644 lib/librte_flow_classify/Makefile create mode 100644 lib/librte_flow_classify/rte_flow_classify.c create mode 100644 lib/librte_flow_classify/rte_flow_classify.h create mode 100644 lib/librte_flow_classify/rte_flow_classify_parse.c create mode 100644 lib/librte_flow_classify/rte_flow_classify_parse.h create mode 100644 lib/librte_flow_classify/rte_flow_classify_version.map create mode 100644 test/test/test_flow_classify.c create mode 100644 test/test/test_flow_classify.h -- 1.9.1
