Detailed Description

Cryptographic Operation.

This structure contains data relating to performing cryptographic operations. This operation structure is used to contain any operation which is supported by the cryptodev API, PMDs should check the type parameter to verify that the operation is a support function of the device. Crypto operations are enqueued and dequeued in crypto PMDs using the rte_cryptodev_enqueue_burst() / rte_cryptodev_dequeue_burst() .

Examples:

examples/ipsec-secgw/esp.c, examples/ipsec-secgw/ipsec.c, examples/l2fwd-crypto/main.c, and examples/vhost_crypto/main.c.

Field Documentation

uint8_t type

operation type

Definition at line 82 of file rte_crypto.h.

uint8_t status

operation status - this is reset to RTE_CRYPTO_OP_STATUS_NOT_PROCESSED on allocation from mempool and will be set to RTE_CRYPTO_OP_STATUS_SUCCESS after crypto operation is successfully processed by a crypto PMD

Examples:

examples/ipsec-secgw/esp.c.

Definition at line 84 of file rte_crypto.h.

uint8_t sess_type

operation session type

Definition at line 92 of file rte_crypto.h.

uint8_t reserved[3]

Reserved bytes to fill 64 bits for future additions

Definition at line 94 of file rte_crypto.h.

uint16_t private_data_offset

Offset to indicate start of private data (if any). The offset is counted from the start of the rte_crypto_op including IV. The private data may be used by the application to store information which should remain untouched in the library/driver

Definition at line 98 of file rte_crypto.h.

struct rte_mempool* mempool

crypto operation mempool which operation is allocated from

Definition at line 107 of file rte_crypto.h.

rte_iova_t phys_addr

physical address of crypto operation

Definition at line 111 of file rte_crypto.h.

struct rte_crypto_sym_op sym[0]

Symmetric operation parameters

Examples:

examples/ipsec-secgw/ipsec.c, and examples/l2fwd-crypto/main.c.
