sess	security session If security session is NULL then global (per security instance) statistics will be retrieved, if supported. Global statistics collection is not dependent on the per session statistics configuration.
stats	statistics

On success, return 0
On failure, a negative value

◆ rte_security_capabilities_get()

const struct rte_security_capability* rte_security_capabilities_get ( void * instance )

Returns array of security instance capabilities

Parameters

instance Security instance.

Returns

Returns array of security capabilities.
Return NULL if no capabilities available.

Examples:: examples/ipsec-secgw/ipsec-secgw.c.

◆ rte_security_capability_get()

const struct rte_security_capability* rte_security_capability_get	(	void *	instance,
		struct rte_security_capability_idx *	idx
	)

Query if a specific capability is available on security instance

Parameters

instance	security instance.
idx	security capability index to match against

Returns

Returns pointer to security capability on match of capability index criteria.
Return NULL if the capability not matched on security instance.

◆ rte_security_rx_inject_configure()

__rte_experimental int rte_security_rx_inject_configure	(	void *	ctx,
		uint16_t	port_id,
		bool	enable
	)

Warning: EXPERIMENTAL: this API may change, or be removed, without prior notice

Configure security device to inject packets to an ethdev port.

This API must be called only when both security device and the ethdev is in stopped state. The security device need to be configured before any packets are submitted to rte_security_inb_pkt_rx_inject API.

Parameters

ctx	Security ctx
port_id	Port identifier of the ethernet device to which packets need to be injected.
enable	Flag to enable and disable connection between a security device and an ethdev port.

Returns

0 if successful.
-EINVAL if context NULL or port_id is invalid.
-EBUSY if devices are not in stopped state.
-ENOTSUP if security device does not support injecting to ethdev port.

◆ rte_security_inb_pkt_rx_inject()

__rte_experimental uint16_t rte_security_inb_pkt_rx_inject	(	void *	ctx,
		struct rte_mbuf **	pkts,
		void **	sess,
		uint16_t	nb_pkts
	)

Warning: EXPERIMENTAL: this API may change, or be removed, without prior notice

Perform security processing of packets and inject the processed packet to ethdev Rx.

Rx inject would behave similarly to ethdev loopback but with the additional security processing. In case of ethdev loopback, application would be submitting packets to ethdev Tx queues and would be received as is from ethdev Rx queues. With Rx inject, packets would be received after security processing from ethdev Rx queues.

With inline protocol offload capable ethdevs, Rx injection can be used to handle packets which failed the regular security Rx path. This can be due to cases such as outer fragmentation, in which case applications can reassemble the fragments and then subsequently submit for inbound processing and Rx injection, so that packets are received as regular security processed packets.

With lookaside protocol offload capable cryptodevs, Rx injection can be used to perform packet parsing after security processing. This would allow for re-classification after security protocol processing is done (ie, inner packet parsing). The ethdev queue on which the packet would be received would be based on rte_flow rules matching the packet after security processing.

The security device which is injecting packets to ethdev Rx need to be configured using rte_security_rx_inject_configure with enable flag set to true before any packets are submitted.

If hash.fdir.h field is set in mbuf, it would be treated as the value for MARK pattern for the subsequent rte_flow parsing. The packet would appear as if it is received from port field in mbuf.

Since the packet would be received back from ethdev Rx queues, it is expected that application retains/adds L2 header with the mbuf field 'l2_len' reflecting the size of L2 header in the packet.

Parameters

ctx	Security ctx
pkts	The address of an array of nb_pkts pointers to rte_mbuf structures which contain the packets.
sess	The address of an array of nb_pkts pointers to security sessions corresponding to each packet.
nb_pkts	The maximum number of packets to process.

Returns: The number of packets successfully injected to ethdev Rx. The return value can be less than the value of the nb_pkts parameter when the PMD internal queues have been filled up.
