Detailed Description

RTE IPsec support. It is not recommended to include this file directly, include <rte_ipsec.h> instead. Contains helper functions to process completed crypto-ops and group related packets by sessions they belong to.

Definition in file rte_ipsec_group.h.

Function Documentation

rte_ipsec_ses_from_crypto()

static struct rte_ipsec_session* rte_ipsec_ses_from_crypto ( const struct rte_crypto_op *  cop )

static

Take crypto-op as an input and extract pointer to related ipsec session.

Parameters

cop	The address of an input rte_crypto_op structure.

Returns

The pointer to the related rte_ipsec_session structure.

Definition at line 45 of file rte_ipsec_group.h.

rte_ipsec_pkt_crypto_group()

static uint16_t rte_ipsec_pkt_crypto_group ( const struct rte_crypto_op *  cop[], struct rte_mbuf *  mb[], struct rte_ipsec_group  grp[], uint16_t  num  )

inlinestatic

Take as input completed crypto ops, extract related mbufs and group them by rte_ipsec_session they belong to. For mbuf which crypto-op wasn't completed successfully RTE_MBUF_F_RX_SEC_OFFLOAD_FAILED will be raised in ol_flags. Note that mbufs with undetermined SA (session-less) are not freed by the function, but are placed beyond mbufs for the last valid group. It is a user responsibility to handle them further.

Parameters

cop	The address of an array of num pointers to the input rte_crypto_op structures.
mb	The address of an array of num pointers to output rte_mbuf structures.
grp	The address of an array of num to output rte_ipsec_group structures.
num	The maximum number of crypto-ops to process.

Returns

Number of filled elements in grp array.
