For e.g., If an eventdev based application is submitting a rte_security_session operation and wants to indicate event information required to construct a new event that will be enqueued to eventdev after completion of the rte_security operation. This patch provides a mechanism for the application to associate this information with the rte_security session. The application can set the private data using rte_security_session_set_private_data() and retrieve it using rte_security_session_get_private_data() Signed-off-by: Abhinandan Gujjar Signed-off-by: Nikhil Rao --- lib/librte_security/rte_security.h | 29 +++++++++++++++++++++++++++++ 1 file changed, 29 insertions(+) diff --git a/lib/librte_security/rte_security.h b/lib/librte_security/rte_security.h index d7362f3..1e8d835 100644 --- a/lib/librte_security/rte_security.h +++ b/lib/librte_security/rte_security.h @@ -559,6 +559,35 @@ struct rte_security_capability_idx { rte_security_capability_get(struct rte_security_ctx *instance, struct rte_security_capability_idx *idx); +/** + * Set private data for a security session. + * + * @param sess security session + * @param data pointer to the private data. + * @param size size of the private data. + * + * @return + * - On success, zero. + * - On failure, a negative value. + */ +int +rte_security_session_set_private_data(struct rte_security_session *sess, + void *data, + uint16_t size); + +/** + * Get private data of a security session. + * + * @param sess security session + * + * @return + * - On success return pointer to private data. + * - On failure returns NULL. + */ +void * +rte_security_session_get_private_data( + const struct rte_security_session *session); + #ifdef __cplusplus } #endif -- 1.9.1
