Definition at line 61 of file rte_crypto.h.

Reset the fields of a crypto operation to their default values.

Parameters

op The crypto operation to be reset.
type The crypto operation type.

Definition at line 196 of file rte_crypto.h.

Returns the size of private data allocated with each rte_crypto_op object by the mempool

Parameters

mempool rte_crypto_op mempool

Returns

private data size

Definition at line 235 of file rte_crypto.h.

Creates a crypto operation pool

Parameters

name pool name
type crypto operation type, use RTE_CRYPTO_OP_TYPE_UNDEFINED for a pool which supports all operation types
nb_elts number of elements in pool
cache_size Number of elements to cache on lcore, see rte_mempool_create for further details about cache size
priv_size Size of private data to allocate with each operation
socket_id Socket to allocate memory on

Returns

  • On success pointer to mempool
  • On failure NULL

Bulk allocate raw element from mempool and return as crypto operations

Parameters

mempool crypto operation mempool.
type crypto operation type.
ops Array to place allocated crypto operations
nb_ops Number of crypto operations to allocate

Returns

•
On success returns number of ops allocated

Definition at line 280 of file rte_crypto.h.

static struct rte_crypto_op * rte_crypto_op_alloc (struct rte_mempool * mempool, enum rte_crypto_op_type type) [inline], [static]

Allocate a crypto operation from a mempool with default parameters set

Parameters

mempool crypto operation mempool
type operation type to allocate

Returns

  • On success returns a valid rte_crypto_op structure
  • On failure returns NULL

Definition at line 308 of file rte_crypto.h.

Bulk allocate crypto operations from a mempool with default parameters set

Parameters

mempool crypto operation mempool
type operation type to allocate
ops Array to place allocated crypto operations
nb_ops Number of crypto operations to allocate

Returns

  • nb_ops if the number of operations requested were allocated.
  • 0 if the requested number of ops are not available. None are allocated in this case.

Definition at line 338 of file rte_crypto.h.

Returns a pointer to the private data of a crypto operation if that operation has enough capacity for requested size.

Parameters

op crypto operation.
size size of space requested in private data.

Returns

  • if sufficient space available returns pointer to start of private data
  • if insufficient space returns NULL

Definition at line 368 of file rte_crypto.h.

free crypto operation structure If operation has been allocate from a rte_mempool, then the operation will be returned to the mempool.

Parameters

op Pointer to symmetric crypto operation allocated with rte_crypto_op_alloc() If op is NULL, no operation is performed.

Definition at line 398 of file rte_crypto.h.

static struct rte_crypto_op * rte_crypto_sym_op_alloc_from_mbuf_priv_data (struct rte_mbuf * m) [inline], [static]

Allocate a symmetric crypto operation in the private data of an mbuf.

Parameters

m mbuf which is associated with the crypto operation, the operation will be allocated in the private data of that mbuf.

Returns

  • On success returns a pointer to the crypto operation.
  • On failure returns NULL.

Definition at line 416 of file rte_crypto.h.

static struct rte_crypto_sym_xform * rte_crypto_op_sym_xforms_alloc (struct rte_crypto_op * op, uint8_t nb_xforms) [inline], [static]

Allocate space for symmetric crypto xforms in the private data space of the crypto operation. This also defaults the crypto xform type and configures the chaining of the xforms in the crypto operation

Returns

  • On success returns pointer to first crypto xform in crypto operations chain
  • On failure returns NULL

Definition at line 450 of file rte_crypto.h.
