For each incoming inbound IPSec-protected packet (ESP or AH) it has to perform a lookup within it’s SAD. Lookup should be performed by: Security Parameters Index (SPI) + destination IP (DIP) + source IP (SIP) or SPI + DIP or SPI only and an implementation has to return the “longest” existing match. These series extend DPDK IPsec library with SAD table implementation that: - conforms to the RFC requirements above - can scale up to millions of entries - supports fast lookups - supports incremental updates Initial series provide an API to create/destroy SAD, and to add/delete/lookup entries within given SAD table. Under the hood it uses three librte_hash tables each of which contains an entries for a specific SA type (either it is addressed by SPI only or SPI+DIP or SPI+DIP+SIP) Also this patch series introduce test-sad application to measure performance of the library. According to our measurements on SKX for 1M entries average lookup cost is ~80 cycles, average add cost ~500 cycles. v6: - fix rte_ipsec_sad_lookup() comments regarding return value - added parallel lookup feature to test-sad app - added read/write concurrency support flag to test-sad app - added programmer's guide - updated release notes v5: - small fix in rte_ipsec_sad_create() - add comments in rte_ipsec_sad.h v4: - fixes in test-sad app - small fixes in rte_ipsec_sad_create() - fixes in test_find_existing() from unittests v3: - fixes in rte_ipsec_sad_create() and rte_ipsec_sad_find_existing() - fix typos - updated commit messages - added test_find_existing() in unittests v2: - various bugs fixed - rte_ipsec_sad_free renamed to rte_ipsec_sad_destroy - added const qualifier to rte_ipsec_sad_key *key for add/delete - added more comments into the code - added ipv6 support into the testsad app - added measurement into the testsad app - random SPI values are generated without dups - added support for configurable burst size in testsad app - added verbose mode into the testsad app Vladimir Medvedkin (6): ipsec: add inbound SAD API ipsec: add SAD create/destroy implementation ipsec: add SAD add/delete/lookup implementation test/ipsec: add ipsec SAD autotests app: add test-sad application doc/ipsec: update ipsec programmer's guide app/Makefile | 1 + app/meson.build | 3 +- app/test-sad/Makefile | 18 + app/test-sad/main.c | 668 +++++++++++++++++++++++++ app/test-sad/meson.build | 6 + app/test/Makefile | 1 + app/test/autotest_data.py | 6 + app/test/meson.build | 1 + app/test/test_ipsec_sad.c | 887 +++++++++++++++++++++++++++++++++ doc/guides/prog_guide/ipsec_lib.rst | 152 ++++++ doc/guides/rel_notes/release_19_11.rst | 3 + lib/librte_ipsec/Makefile | 4 +- lib/librte_ipsec/ipsec_sad.c | 515 +++++++++++++++++++ lib/librte_ipsec/meson.build | 6 +- lib/librte_ipsec/rte_ipsec_sad.h | 176 +++++++ lib/librte_ipsec/rte_ipsec_version.map | 7 + 16 files changed, 2449 insertions(+), 5 deletions(-) create mode 100644 app/test-sad/Makefile create mode 100644 app/test-sad/main.c create mode 100644 app/test-sad/meson.build create mode 100644 app/test/test_ipsec_sad.c create mode 100644 lib/librte_ipsec/ipsec_sad.c create mode 100644 lib/librte_ipsec/rte_ipsec_sad.h -- 2.7.4
