Field Documentation uint32_t esn Extended Sequence Numbers (ESN) * 1: Use extended (64 bit) sequence numbers * 0: Use normal sequence numbers Definition at line 117 of file rte_security.h. uint32_t udp_encap UDP encapsulation * 1: Do UDP encapsulation/decapsulation so that IPSEC packets can traverse through NAT boxes. * 0: No UDP encapsulation Definition at line 125 of file rte_security.h. uint32_t copy_dscp Copy DSCP bits * 1: Copy IPv4 or IPv6 DSCP bits from inner IP header to the outer IP header in encapsulation, and vice versa in decapsulation. * 0: Do not change DSCP field. Definition at line 134 of file rte_security.h. uint32_t copy_flabel Copy IPv6 Flow Label * 1: Copy IPv6 flow label from inner IPv6 header to the outer IPv6 header. * 0: Outer header is not modified. Definition at line 142 of file rte_security.h. uint32_t copy_df Copy IPv4 Don't Fragment bit * 1: Copy the DF bit from the inner IPv4 header to the outer IPv4 header. * 0: Outer header is not modified. Definition at line 150 of file rte_security.h. uint32_t dec_ttl Decrement inner packet Time To Live (TTL) field * 1: In tunnel mode, decrement inner packet IPv4 TTL or IPv6 Hop Limit af- ter tunnel decapsulation, or before tunnel encapsulation. * 0: Inner packet is not modified. Definition at line 159 of file rte_security.h. uint32_t ecn Explicit Congestion Notification (ECN) * 1: In tunnel mode, enable outer header ECN Field copied from inner header in tunnel encapsulation, or inner header ECN field construction in decap- sulation. * 0: Inner/outer header are not modified. Definition at line 168 of file rte_security.h. uint32_t stats Security statistics * 1: Enable per session security statistics collection for this SA, if sup- ported by the driver. * 0: Disable per session security statistics collection for this SA. Definition at line 176 of file rte_security.h. uint32_t iv_gen_disable Disable IV generation in PMD * 1: Disable IV generation in PMD. When disabled, IV provided in rte_crypto_op will be used by the PMD. * 0: Enable IV generation in PMD. When enabled, PMD generated random value would be used and application is not required to provide IV. Note: For inline cases, IV generation would always need to be handled by the PMD. Definition at line 190 of file rte_security.h. uint32_t tunnel_hdr_verify Verify tunnel header in inbound * RTE_SECURITY_IPSEC_TUNNEL_VERIFY_DST_ADDR: Verify destination IP address. * RTE_SECURITY_IPSEC_TUNNEL_VERIFY_SRC_DST_ADDR: Verify both source and destination IP addresses. Definition at line 199 of file rte_security.h. uint32_t udp_ports_verify Verify UDP encapsulation ports in inbound * 1: Match UDP source and destination ports * 0: Do not match UDP ports Definition at line 206 of file rte_security.h. uint32_t ip_csum_enable Compute/verify inner packet IPv4 header checksum in tunnel mode * 1: For outbound, compute inner packet IPv4 header checksum before tunnel encapsulation and for inbound, verify after tunnel decapsulation. * 0: Inner packet IP header checksum is not computed/verified. The checksum verification status would be set in mbuf using RTE_MBUF_F_RX_IP_CKSUM_xxx flags. Inner IP checksum computation can also be enabled(per operation) by setting the flag RTE_MBUF_F_TX_IP_CKSUM in mbuf. Definition at line 221 of file rte_security.h. uint32_t l4_csum_enable Compute/verify inner packet L4 checksum in tunnel mode * 1: For outbound, compute inner packet L4 checksum before tunnel encapsu- lation and for inbound, verify after tunnel decapsulation. * 0: Inner packet L4 checksum is not computed/verified. The checksum verification status would be set in mbuf using RTE_MBUF_F_RX_L4_CKSUM_xxx flags. Inner L4 checksum computation can also be enabled(per operation) by setting the flags RTE_MBUF_F_TX_TCP_CKSUM or RTE_MBUF_F_TX_SCTP_CKSUM or RTE_MBUF_F_TX_UDP_CKSUM or RTE_MBUF_F_TX_L4_MASK in mbuf. Definition at line 237 of file rte_security.h. uint32_t ip_reassembly_en Enable IP reassembly on inline inbound packets. * 1: Enable driver to try reassembly of encrypted IP packets for this SA, if supported by the driver. This feature will work only if user has suc- cessfully set IP reassembly config params using rte_eth_ip_reassem- bly_conf_set() for the inline Ethernet device. PMD need to register mbuf dynamic fields using rte_eth_ip_reassembly_dynfield_register() and secu- rity session creation would fail if dynfield is not registered success- fully. * 0: Disable IP reassembly of packets (default). Definition at line 250 of file rte_security.h. uint32_t ingress_oop Enable out of place processing on inline inbound packets. * 1: Enable driver to perform Out-of-place(OOP) processing for this inline inbound SA if supported by driver. PMD need to register mbuf dynamic field using rte_security_oop_dynfield_register() and security session creation would fail if dynfield is not registered successfully. * 0: Disable OOP processing for this session (default).
