Definition in file rte_ipsec_sa.h. Macro Definition Documentation #define RTE_IPSEC_SAFLAG_SQN_ATOM (1ULL << 0) Indicates that SA will(/will not) need an 'atomic' access to sequence num- ber and replay window. 'atomic' here means: functions: * rte_ipsec_pkt_crypto_prepare * rte_ipsec_pkt_process can be safely used in MT environment, as long as the user can guarantee that they obey multiple readers/single writer model for SQN+replay_window operations. To be more specific: for outbound SA there are no restrictions. for inbound SA the caller has to guarantee that at any given moment only one thread is executing rte_ipsec_pkt_process() for given SA. Note that it is caller responsibil- ity to maintain correct order of packets to be processed. In other words - it is a caller responsibility to serialize process() invocations.

Enumeration Type Documentation anonymous enum SA type is an 64-bit value that contain the following information: * IP version (IPv4/IPv6) * IPsec proto (ESP/AH) * inbound/outbound * mode (TRANSPORT/TUNNEL) * for TUNNEL outer IP version (IPv4/IPv6) * are SA SQN operations 'atomic' * ESN enabled/disabled * NAT-T UDP encapsulated (TUNNEL mode only) ... Definition at line 85 of file rte_ipsec_sa.h. Function Documentation uint64_t rte_ipsec_sa_type (const struct rte_ipsec_sa * sa) get type of given SA Returns SA type value. int rte_ipsec_sa_size (const struct rte_ipsec_sa_prm * prm) Calculate required SA size based on provided input parameters. Parameters prm Parameters that will be used to initialise SA object. Returns * Actual size required for SA with given parameters. * -EINVAL if the parameters are invalid. int rte_ipsec_sa_init (struct rte_ipsec_sa * sa, const struct rte_ipsec_sa_prm * prm, uint32_t size) initialise SA based on provided input parameters. Parameters sa SA object to initialise. prm Parameters used to initialise given SA object. size size of the provided buffer for SA. Returns * Actual size of SA object if operation completed successfully. * -EINVAL if the parameters are invalid. * -ENOSPC if the size of the provided buffer is not big enough. void rte_ipsec_sa_fini (struct rte_ipsec_sa * sa) cleanup SA Parameters sa Pointer to SA object to de-initialize.
