Function Documentation

rte_ipsec_sad_add()

int rte_ipsec_sad_add	(	struct rte_ipsec_sad *	sad,
		const union rte_ipsec_sad_key *	key,
		int	key_type,
		void *	sa
	)

Add a rule into the SAD. Could be safely called with concurrent lookups if RTE_IPSEC_SAD_FLAG_RW_CONCURRENCY flag was configured on creation time. While with this flag multi-reader - one-writer model Is MT safe, multi-writer model is not and required extra synchronisation.

Parameters

sad	SAD object handle
key	pointer to the key
key_type	key type (spi only/spi+dip/spi+dip+sip)
sa	Pointer associated with the key to save in a SAD Must be 4 bytes aligned.

Returns

0 on success, negative value otherwise

Examples:

examples/ipsec-secgw/sad.c.

rte_ipsec_sad_del()

int rte_ipsec_sad_del	(	struct rte_ipsec_sad *	sad,
		const union rte_ipsec_sad_key *	key,
		int	key_type
	)

Delete a rule from the SAD. Could be safely called with concurrent lookups if RTE_IPSEC_SAD_FLAG_RW_CONCURRENCY flag was configured on creation time. While with this flag multi-reader - one-writer model Is MT safe, multi-writer model is not and required extra synchronisation.

Parameters

sad	SAD object handle
key	pointer to the key
key_type	key type (spi only/spi+dip/spi+dip+sip)

Returns

0 on success, negative value otherwise

rte_ipsec_sad_find_existing()

struct rte_ipsec_sad* rte_ipsec_sad_find_existing

(

const char *

name

)

Find an existing SAD object and return a pointer to it.

Parameters

name	Name of the SAD object as passed to rte_ipsec_sad_create()

Returns

Pointer to sad object or NULL if object not found with rte_errno set appropriately. Possible rte_errno values include:

• ENOENT - required entry not available to return.

rte_ipsec_sad_destroy()

void rte_ipsec_sad_destroy

(

struct rte_ipsec_sad *

sad

)

Destroy SAD object.

Parameters

sad	pointer to the SAD object

rte_ipsec_sad_lookup()

int rte_ipsec_sad_lookup	(	const struct rte_ipsec_sad *	sad,
		const union rte_ipsec_sad_key *	keys[],
		void *	sa[],
		uint32_t	n
	)

Lookup multiple keys in the SAD.

Parameters

sad	SAD object handle
keys	Array of keys to be looked up in the SAD
sa	Pointer associated with the keys. If the lookup for the given key failed, then corresponding sa will be NULL
n	Number of elements in keys array to lookup.

Returns

-EINVAL for incorrect arguments, otherwise number of successful lookups.
