Detailed Description

IPSEC Security Association (SA) parameters.

Examples: odp_ipsec.c, and odp_ipsecfwd.c.

Definition at line 837 of file api/spec/ipsec_types.h.

Field Documentation

◆ proto

odp_ipsec_protocol_t odp_ipsec_sa_param_t::proto

IPSEC protocol: ESP or AH.

The default value is ODP_IPSEC_ESP.

Examples: odp_ipsec.c.

Definition at line 842 of file api/spec/ipsec_types.h.

◆ dest_queue

odp_queue_t odp_ipsec_sa_param_t::dest_queue

Destination queue for IPSEC events.

Operations in asynchronous or inline mode enqueue resulting events into this queue. The default queue ('default_queue') is used when SA is not known.

Examples: odp_ipsec.c, and odp_ipsecfwd.c.

Definition at line 865 of file api/spec/ipsec_types.h.

◆ context

void* odp_ipsec_sa_param_t::context

User defined SA context pointer.

User defined context pointer associated with the SA. The implementation may prefetch the context data. Default value of the pointer is NULL.

Definition at line 873 of file api/spec/ipsec_types.h.

◆ context_len

uint32_t odp_ipsec_sa_param_t::context_len

Context data length.

User defined context data length in bytes for prefetching. The implementation may use this value as a hint for the number of context data bytes to prefetch. Default value is zero (no hint).

Definition at line 881 of file api/spec/ipsec_types.h.

◆

struct { ... } odp_ipsec_sa_param_t::lookup_param

Additional SA lookup parameters.

Values are considered only in ODP_IPSEC_LOOKUP_DSTADDR_SPI lookup mode.

◆ antireplay_ws

uint32_t odp_ipsec_sa_param_t::antireplay_ws

Minimum anti-replay window size.

Use 0 to disable anti-replay service. The default value is 0.

Definition at line 908 of file api/spec/ipsec_types.h.

◆ pipeline

odp_ipsec_pipeline_t odp_ipsec_sa_param_t::pipeline

Select pipelined destination for resulting events.

Asynchronous and inline modes generate events. Select where those events are sent. Inbound SAs may choose to use pipelined classification. The default value is ODP_IPSEC_PIPELINE_NONE.

Definition at line 917 of file api/spec/ipsec_types.h.

◆ dest_cos

odp_cos_t odp_ipsec_sa_param_t::dest_cos

Classifier destination CoS for resulting packets.

Successfully decapsulated packets are sent to classification through this CoS. Other resulting events are sent to 'dest_queue'. This field is considered only when 'pipeline' is ODP_IPSEC_PIPELINE_CLS. The CoS must not be shared between any pktio interface default CoS. The maximum number of different CoS supported is defined by IPSEC capability max_cls_cos.

Definition at line 930 of file api/spec/ipsec_types.h.

◆ reassembly_en

odp_bool_t odp_ipsec_sa_param_t::reassembly_en

Enable reassembly of IPsec tunneled fragments.

Attempt reassembly of fragments after IPsec tunnel decapsulation.

Reassembly is attempted for inline or asynchronously processed packets, not for packets processed using the synchronous API function.

Fragments received through different SAs will not be reassembled into the same packet.

IPsec statistics reflect IPsec processing before reassembly and thus count all individual fragments.

Reassembly may be enabled for an SA only if reassembly was enabled in the global IPsec configuration.

Default value is false.

See also: odp_ipsec_config()

Definition at line 956 of file api/spec/ipsec_types.h.

◆ mtu

uint32_t odp_ipsec_sa_param_t::mtu

MTU for outbound IP fragmentation offload.

This is the maximum length of IP packets that outbound IPSEC operations may produce. The value may be updated later with odp_ipsec_sa_mtu_update().
