RTE IPsec security association database (SAD) support. Contains helper functions to lookup and maintain SAD

Definition in file rte_ipsec_sad.h.

Max number of characters in SAD name.

Definition at line 52 of file rte_ipsec_sad.h.

Flag to create SAD with ipv6 dip and sip addresses

Definition at line 54 of file rte_ipsec_sad.h.

Flag to support reader writer concurrency

Definition at line 56 of file rte_ipsec_sad.h.

Type of key

Definition at line 27 of file rte_ipsec_sad.h.

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

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

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.

Destroy SAD object.

Parameters

sad pointer to the SAD object

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.
