Detailed Description

RTE pdump

packet dump library to provide packet capturing support on dpdk.

Definition in file rte_pdump.h.

Function Documentation

◆ rte_pdump_init()

int rte_pdump_init ( void )

Initialize packet capturing handling

Register the IPC action for communication with target (primary) process.

Returns: 0 on success, -1 on error

◆ rte_pdump_uninit()

int rte_pdump_uninit ( void )

Un initialize packet capturing handling

Unregister the IPC action for communication with target (primary) process.

Returns: 0 on success, -1 on error

◆ rte_pdump_enable()

int rte_pdump_enable	(	uint16_t	port,
		uint16_t	queue,
		uint32_t	flags,
		struct rte_ring *	ring,
		struct rte_mempool *	mp,
		void *	filter
	)

Enables packet capturing on given port and queue.

Parameters

port	port on which packet capturing should be enabled.
queue	queue of a given port on which packet capturing should be enabled. users should pass on value UINT16_MAX to enable packet capturing on all queues of a given port.
flags	flags specifies RTE_PDUMP_FLAG_RX/RTE_PDUMP_FLAG_TX/RTE_PDUMP_FLAG_RXTX on which packet capturing should be enabled for a given port and queue.
ring	ring on which captured packets will be enqueued for user.
mp	mempool on to which original packets will be mirrored or duplicated.
filter	Unused should be NULL.

Returns: 0 on success, -1 on error, rte_errno is set accordingly.

◆ rte_pdump_enable_bpf()

__rte_experimental int rte_pdump_enable_bpf	(	uint16_t	port_id,
		uint16_t	queue,
		uint32_t	flags,
		uint32_t	snaplen,
		struct rte_ring *	ring,
		struct rte_mempool *	mp,
		const struct rte_bpf_prm *	prm
	)

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

Enables packet capturing on given port and queue with filtering.

Parameters

port_id	The Ethernet port on which packet capturing should be enabled.
queue	The queue on the Ethernet port which packet capturing should be enabled. Pass UINT16_MAX to enable packet capturing on all queues of a given port.
flags	Pdump library flags that specify direction and packet format.
snaplen	The upper limit on bytes to copy. Passing UINT32_MAX means capture all the possible data.
ring	The ring on which captured packets will be enqueued for user.
mp	The mempool on to which original packets will be mirrored or duplicated.
prm	Use BPF program to run to filter packes (can be NULL)

Returns: 0 on success, -1 on error, rte_errno is set accordingly.

◆ rte_pdump_disable()

int rte_pdump_disable	(	uint16_t	port,
		uint16_t	queue,
		uint32_t	flags
	)

Disables packet capturing on given port and queue.

Parameters

port	port on which packet capturing should be disabled.
queue	queue of a given port on which packet capturing should be disabled. users should pass on value UINT16_MAX to disable packet capturing on all queues of a given port.
flags	flags specifies RTE_PDUMP_FLAG_RX/RTE_PDUMP_FLAG_TX/RTE_PDUMP_FLAG_RXTX on which packet capturing should be enabled for a given port and queue.

Returns: 0 on success, -1 on error, rte_errno is set accordingly.

◆ rte_pdump_enable_by_deviceid()

int rte_pdump_enable_by_deviceid	(	char *	device_id,
		uint16_t	queue,
		uint32_t	flags,
		struct rte_ring *	ring,
		struct rte_mempool *	mp,
		void *	filter
	)

Enables packet capturing on given device id and queue. device_id can be name or pci address of device.

Parameters

device_id	device id on which packet capturing should be enabled.
queue	queue of a given device id on which packet capturing should be enabled. users should pass on value UINT16_MAX to enable packet capturing on all queues of a given device id.
flags	flags specifies RTE_PDUMP_FLAG_RX/RTE_PDUMP_FLAG_TX/RTE_PDUMP_FLAG_RXTX on which packet capturing should be enabled for a given port and queue.
ring	ring on which captured packets will be enqueued for user.
mp	mempool on to which original packets will be mirrored or duplicated.
filter	unused should be NULL

Returns: 0 on success, -1 on error, rte_errno is set accordingly.

◆ rte_pdump_enable_bpf_by_deviceid()

__rte_experimental int rte_pdump_enable_bpf_by_deviceid	(	const char *	device_id,
		uint16_t	queue,
		uint32_t	flags,
		uint32_t	snaplen,
		struct rte_ring *	ring,
		struct rte_mempool *	mp,
		const struct rte_bpf_prm *	filter
	)

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

Enables packet capturing on given device id and queue with filtering. device_id can be name or pci address of device.

Parameters

device_id	device id on which packet capturing should be enabled.
queue	The queue on the Ethernet port which packet capturing should be enabled. Pass UINT16_MAX to enable packet capturing on all queues of a given port.
flags	Pdump library flags that specify direction and packet format.
snaplen	The upper limit on bytes to copy. Passing UINT32_MAX means capture all the possible data.
ring	The ring on which captured packets will be enqueued for user.
