Field Documentation

◆ tfc_dummy

uint32_t odp_ipsec_out_opt_t::tfc_dummy

Tunnel mode TFC dummy packet.

This can be used only in tunnel mode. When the flag is set, packet length and content is ignored and instead a TFC dummy packet is created during IPSEC operation. The dummy packet length is defined by 'tfc_pad_len' option. If the SA is configured to copy IP header fields from inner IP packet, those fields must be passed with IP parameters option.

Definition at line 1233 of file api/spec/ipsec_types.h.

◆

struct { ... } odp_ipsec_out_opt_t::flag

Option flags.

Set flag for those options that are used, all other options are ignored.

◆ all_flags

uint32_t odp_ipsec_out_opt_t::all_flags

All flag bits.

This field can be used to set/clear all flags, or to perform bitwise operations over those.

Definition at line 1244 of file api/spec/ipsec_types.h.

◆ tfc_pad_len

uint32_t odp_ipsec_out_opt_t::tfc_pad_len

TFC padding length.

Number of TFC padding bytes added to the packet during IPSEC processing. Resulting packet should not exceed the maximum packet length of the pool, otherwise IPSEC operation may fail. Implementation guarantees that the padding does not contain any confidential information.

Definition at line 1257 of file api/spec/ipsec_types.h.

◆ ipv4

odp_ipsec_ipv4_param_t odp_ipsec_out_opt_t::ipv4

Override IPv4 parameters in outer header creation.

IP addresses are ignored.

Definition at line 1263 of file api/spec/ipsec_types.h.

◆ ipv6

odp_ipsec_ipv6_param_t odp_ipsec_out_opt_t::ipv6

Override IPv6 parameters in outer header creation.
