    "content": "According to RFC 4301 IPSec implementation needs an inbound SA database (SAD).\nFor each incoming inbound IPSec-protected packet (ESP or AH) it has to\nperform a lookup within it’s SAD.\nLookup should be performed by:\nSecurity Parameters Index (SPI) + destination IP (DIP) + source IP (SIP)\n  or SPI + DIP\n  or SPI only\nand an implementation has to return the “longest” existing match.\nThese series extend DPDK IPsec library with SAD table implementation that:\n- conforms to the RFC requirements above\n- can scale up to millions of entries\n- supports fast lookups\n- supports incremental updates\n\nInitial series provide an API to create/destroy SAD, and to\nadd/delete/lookup entries within given SAD table.\nUnder the hood it uses three librte_hash tables each of which contains\nan entries for a specific SA type (either it is addressed by SPI only\nor SPI+DIP or SPI+DIP+SIP) Also this patch series introduce test-sad\napplication to measure performance of the library. According to our\nmeasurements on SKX for 1M entries average lookup cost is ~80 cycles,\naverage add cost ~500 cycles.\n\nNext Steps:\n- integration with ipsec-secgw\n\nVladimir Medvedkin (5):\n  ipsec: add inbound SAD API\n  ipsec: add SAD create/free API\n  ipsec: add SAD add/delete/lookup implementation\n  test/ipsec: add ipsec SAD autotests\n  app: add test-sad application\n\n app/Makefile                           |   1 +\n app/meson.build                        |   3 +-\n app/test-sad/Makefile                  |  18 +\n app/test-sad/main.c                    | 420 ++++++++++++++++\n app/test-sad/meson.build               |   6 +\n app/test/Makefile                      |   1 +\n app/test/autotest_data.py              |   6 +\n app/test/meson.build                   |   1 +\n app/test/test_ipsec_sad.c              | 874 +++++++++++++++++++++++++++++++++\n lib/librte_ipsec/Makefile              |   4 +-\n lib/librte_ipsec/ipsec_sad.c           | 478 ++++++++++++++++++\n lib/librte_ipsec/meson.build           |   6 +-\n lib/librte_ipsec/rte_ipsec_sad.h       | 174 +++++++\n lib/librte_ipsec/rte_ipsec_version.map |   7 +\n 14 files changed, 1994 insertions(+), 5 deletions(-)\n create mode 100644 app/test-sad/Makefile\n create mode 100644 app/test-sad/main.c\n create mode 100644 app/test-sad/meson.build\n create mode 100644 app/test/test_ipsec_sad.c\n create mode 100644 lib/librte_ipsec/ipsec_sad.c\n create mode 100644 lib/librte_ipsec/rte_ipsec_sad.h"
