Inline processing is limited to a specified subset of traffic. It is often unable to handle more complicated situations, such as fragmented traffic. When using inline processing such traffic is dropped.
Introduce multiple sessions per SA allowing to configure a fallback lookaside session for packets that normally would be dropped. A fallback session type in the SA configuration by adding 'fallback' with 'lookaside-none' or 'lookaside-protocol' parameter to determine type of session. Fallback session feature is available only when using librte_ipsec. v1 to v2 changes: - disable fallback offload for outbound SAs - add test scripts Marcin Smoczynski (3): examples/ipsec-secgw: ipsec_sa structure cleanup examples/ipsec-secgw: add fallback session feature examples/ipsec-secgw: add offload fallback tests doc/guides/sample_app_ug/ipsec_secgw.rst | 17 +- examples/ipsec-secgw/esp.c | 35 ++-- examples/ipsec-secgw/ipsec-secgw.c | 16 +- examples/ipsec-secgw/ipsec.c | 99 ++++++----- examples/ipsec-secgw/ipsec.h | 61 +++++-- examples/ipsec-secgw/ipsec_process.c | 113 +++++++----- examples/ipsec-secgw/sa.c | 164 +++++++++++++----- .../test/trs_aesgcm_common_defs.sh | 4 +- .../trs_aesgcm_inline_crypto_fallback_defs.sh | 5 + .../test/tun_aesgcm_common_defs.sh | 6 +- .../tun_aesgcm_inline_crypto_fallback_defs.sh | 5 + 11 files changed, 358 insertions(+), 167 deletions(-) create mode 100644 examples/ipsec-secgw/test/trs_aesgcm_inline_crypto_fallback_defs.sh create mode 100644 examples/ipsec-secgw/test/tun_aesgcm_inline_crypto_fallback_defs.sh -- 2.21.0.windows.1
