Enumeration Type Documentation

rte_flow_item_type

enum rte_flow_item_type

Matching pattern item types.

Pattern items fall in two categories:

• Matching protocol headers and packet data, usually associated with a specification structure. These must be stacked in the same order as the protocol layers to match inside packets, starting from the lowest.
• Matching meta-data or affecting pattern processing, often without a specification structure. Since they do not match packet contents, their position in the list is usually not relevant.

See the description of individual types for more information. Those marked with [META] fall into the second category.

rte_flow_action_type

enum rte_flow_action_type

Action types.

Each possible action is represented by a type. Some have associated configuration structures. Several actions combined in a list can be assigned to a flow rule and are performed in order.

They fall in three categories:

• Actions that modify the fate of matching traffic, for instance by dropping or assigning it a specific destination.
• Actions that modify matching traffic contents or its properties. This includes adding/removing encapsulation, encryption, compression and marks.
• Actions related to the flow rule itself, such as updating counters or making it non-terminating.

Flow rules being terminating by default, not specifying any action of the fate kind results in undefined behavior. This applies to both ingress and egress.

PASSTHRU, when supported, makes a flow rule non-terminating.

Enumerator
RTE_FLOW_ACTION_TYPE_END	End marker for action lists. Prevents further processing of actions, thereby ending the list. No associated configuration structure.
RTE_FLOW_ACTION_TYPE_VOID	Used as a placeholder for convenience. It is ignored and simply discarded by PMDs. No associated configuration structure.
RTE_FLOW_ACTION_TYPE_PASSTHRU	Leaves traffic up for additional processing by subsequent flow rules; makes a flow rule non-terminating. No associated configuration structure.
RTE_FLOW_ACTION_TYPE_JUMP	RTE_FLOW_ACTION_TYPE_JUMP Redirects packets to a group on the current device. See struct rte_flow_action_jump.
RTE_FLOW_ACTION_TYPE_MARK	Attaches an integer value to packets and sets PKT_RX_FDIR and PKT_RX_FDIR_ID mbuf flags. See struct rte_flow_action_mark.
RTE_FLOW_ACTION_TYPE_FLAG	Flags packets. Similar to MARK without a specific value; only sets the PKT_RX_FDIR mbuf flag. No associated configuration structure.
RTE_FLOW_ACTION_TYPE_QUEUE	Assigns packets to a given queue index. See struct rte_flow_action_queue.
RTE_FLOW_ACTION_TYPE_DROP	Drops packets. PASSTHRU overrides this action if both are specified. No associated configuration structure.
RTE_FLOW_ACTION_TYPE_COUNT	Enables counters for this flow rule. These counters can be retrieved and reset through rte_flow_query(), see struct rte_flow_query_count. See struct rte_flow_action_count.
RTE_FLOW_ACTION_TYPE_RSS	Similar to QUEUE, except RSS is additionally performed on packets to spread them among several queues according to the provided parameters. See struct rte_flow_action_rss.

Function Documentation

rte_flow_validate()

int rte_flow_validate	(	uint16_t	port_id,
		const struct rte_flow_attr *	attr,
		const struct rte_flow_item	pattern[],
		const struct rte_flow_action	actions[],
		struct rte_flow_error *	error
	)

Check whether a flow rule can be created on a given port.

The flow rule is validated for correctness and whether it could be accepted by the device given sufficient resources. The rule is checked against the current device mode and queue configuration. The flow rule may also optionally be validated against existing flow rules and device resources. This function has no effect on the target device.

The returned value is guaranteed to remain valid only as long as no successful calls to rte_flow_create() or rte_flow_destroy() are made in the meantime and no device parameter affecting flow rules in any way are modified, due to possible collisions or resource limitations (although in such cases EINVAL should not be returned).

Parameters

	port_id	Port identifier of Ethernet device.
[in]	attr	Flow rule attributes.
[in]	pattern	Pattern specification (list terminated by the END pattern item).
[in]	actions	Associated actions (list terminated by the END action).
[out]	error	Perform verbose error reporting if not NULL. PMDs initialize this structure in case of error only.

Returns

0 if flow rule is valid and can be created. A negative errno value otherwise (rte_errno is also set), the following errors are defined:

-ENOSYS: underlying device does not support this functionality.

-EIO: underlying device is removed.

-EINVAL: unknown or invalid rule specification.

-ENOTSUP: valid but unsupported rule specification (e.g. partial bit-masks are unsupported).

-EEXIST: collision with an existing rule. Only returned if device supports flow rule collision checking and there was a flow rule collision. Not receiving this return code is no guarantee that creating the rule will not fail due to a collision.

-ENOMEM: not enough memory to execute the function, or if the device supports resource validation, resource limitation on the device.

-EBUSY: action cannot be performed due to busy device resources, may succeed if the affected queues or even the entire port are in a stopped state (see rte_eth_dev_rx_queue_stop() and rte_eth_dev_stop()).

Examples

examples/flow_filtering/flow_blocks.c, and examples/ipsec-secgw/ipsec.c.

rte_flow_create()

struct rte_flow* rte_flow_create	(	uint16_t	port_id,
		const struct rte_flow_attr *	attr,
		const struct rte_flow_item	pattern[],
		const struct rte_flow_action	actions[],
		struct rte_flow_error *	error
	)

Create a flow rule on a given port.

Parameters

	port_id	Port identifier of Ethernet device.
[in]	attr	Flow rule attributes.
[in]	pattern	Pattern specification (list terminated by the END pattern item).
[in]	actions	Associated actions (list terminated by the END action).
[out]	error	Perform verbose error reporting if not NULL. PMDs initialize this structure in case of error only.

Returns

A valid handle in case of success, NULL otherwise and rte_errno is set to the positive version of one of the error codes defined for rte_flow_validate().

Examples

examples/flow_filtering/flow_blocks.c, and examples/ipsec-secgw/ipsec.c.

rte_flow_destroy()

int rte_flow_destroy	(	uint16_t	port_id,
		struct rte_flow *	flow,
		struct rte_flow_error *	error
	)

Destroy a flow rule on a given port.

Failure to destroy a flow rule handle may occur when other flow rules depend on it, and destroying it would result in an inconsistent state.

This function is only guaranteed to succeed if handles are destroyed in reverse order of their creation.

Parameters

	port_id	Port identifier of Ethernet device.
	flow	Flow rule handle to destroy.
[out]	error	Perform verbose error reporting if not NULL. PMDs initialize this structure in case of error only.

Returns

0 on success, a negative errno value otherwise and rte_errno is set.

rte_flow_flush()

int rte_flow_flush	(	uint16_t	port_id,
		struct rte_flow_error *	error
	)

Destroy all flow rules associated with a port.

In the unlikely event of failure, handles are still considered destroyed and no longer valid but the port must be assumed to be in an inconsistent state.

Parameters

	port_id	Port identifier of Ethernet device.
[out]	error	Perform verbose error reporting if not NULL. PMDs initialize this structure in case of error only.

Returns

0 on success, a negative errno value otherwise and rte_errno is set.

Examples

examples/flow_filtering/main.c.

rte_flow_query()

int rte_flow_query	(	uint16_t	port_id,
		struct rte_flow *	flow,
		const struct rte_flow_action *	action,
		void *	data,
		struct rte_flow_error *	error
	)

Query an existing flow rule.

This function allows retrieving flow-specific data such as counters. Data is gathered by special actions which must be present in the flow rule definition.

See also

RTE_FLOW_ACTION_TYPE_COUNT

Parameters

	port_id	Port identifier of Ethernet device.
	flow	Flow rule handle to query.
	action	Action definition as defined in original flow rule.
[in,out]	data	Pointer to storage for the associated query data type.
[out]	error	Perform verbose error reporting if not NULL. PMDs initialize this structure in case of error only.

Returns

0 on success, a negative errno value otherwise and rte_errno is set.

rte_flow_isolate()

int rte_flow_isolate	(	uint16_t	port_id,
		int	set,
		struct rte_flow_error *	error
	)

Restrict ingress traffic to the defined flow rules.

Isolated mode guarantees that all ingress traffic comes from defined flow rules only (current and future).

Besides making ingress more deterministic, it allows PMDs to safely reuse resources otherwise assigned to handle the remaining traffic, such as global RSS configuration settings, VLAN filters, MAC address entries, legacy filter API rules and so on in order to expand the set of possible flow rule types.

Calling this function as soon as possible after device initialization, ideally before the first call to rte_eth_dev_configure(), is recommended to avoid possible failures due to conflicting settings.

Once effective, leaving isolated mode may not be possible depending on PMD implementation.

Additionally, the following functionality has no effect on the underlying port and may return errors such as ENOTSUP ("not supported"):

• Toggling promiscuous mode.
• Toggling allmulticast mode.
• Configuring MAC addresses.
• Configuring multicast addresses.
• Configuring VLAN filters.
• Configuring Rx filters through the legacy API (e.g. FDIR).
• Configuring global RSS settings.

Parameters

	port_id	Port identifier of Ethernet device.
	set	Nonzero to enter isolated mode, attempt to leave it otherwise.
[out]	error	Perform verbose error reporting if not NULL. PMDs initialize this structure in case of error only.

Returns

0 on success, a negative errno value otherwise and rte_errno is set.

rte_flow_error_set()

int rte_flow_error_set	(	struct rte_flow_error *	error,
		int	code,
		enum rte_flow_error_type	type,
		const void *	cause,
		const char *	message
	)

Initialize flow error structure.

Parameters

[out]	error	Pointer to flow error structure (may be NULL).
	code	Related error code (rte_errno).
	type	Cause field and error types.
	cause	Object responsible for the error.
	message	Human-readable error message.

Returns

Negative error code (errno value) and rte_errno is set.

rte_flow_copy()

__rte_deprecated size_t rte_flow_copy	(	struct rte_flow_desc *	fd,
		size_t	len,
		const struct rte_flow_attr *	attr,
		const struct rte_flow_item *	items,
		const struct rte_flow_action *	actions
	)

Deprecated:

Copy an rte_flow rule description.

This interface is kept for compatibility with older applications but is implemented as a wrapper to rte_flow_conv(). It is deprecated due to its lack of flexibility and reliance on a type unusable with C++ programs (struct rte_flow_desc).

Parameters

[in]	fd	Flow rule description.
[in]	len	Total size of allocated data for the flow description.
[in]	attr	Flow rule attributes.
[in]	items	Pattern specification (list terminated by the END pattern item).
[in]	actions	Associated actions (list terminated by the END action).

Returns

If len is greater or equal to the size of the flow, the total size of the flow description and its data. If len is lower than the size of the flow, the number of bytes that would have been written to desc had it been sufficient. Nothing is written.

rte_flow_conv()

__rte_experimental int rte_flow_conv	(	enum rte_flow_conv_op	op,
		void *	dst,
		size_t	size,
		const void *	src,
		struct rte_flow_error *	error
	)

Flow object conversion helper.

This function performs conversion of various flow API objects to a pre-allocated destination buffer. See enum rte_flow_conv_op for possible operations and details about each of them.

Since destination buffer must be large enough, it works in a manner reminiscent of snprintf():

• If size is 0, dst may be a NULL pointer, otherwise dst must be non-NULL.
• If positive, the returned value represents the number of bytes needed to store the conversion of src to dst according to op regardless of the size parameter.
• Since no more than size bytes can be written to dst, output is truncated and may be inconsistent when the returned value is larger than that.
• In case of conversion error, a negative error code is returned and dst contents are unspecified.

Parameters

	op	Operation to perform, related to the object type of dst.
[out]	dst	Destination buffer address. Must be suitably aligned by the caller.
	size	Destination buffer size in bytes.
[in]	src	Source object to copy. Depending on op, its type may differ from that of dst.
[out]	error	Perform verbose error reporting if not NULL. Initialized in case of error only.

Returns

The number of bytes required to convert src to dst on success, a negative errno value otherwise and rte_errno is set.
