Functions

__DOCA_EXPERIMENTAL void doca_ct_destroy ( void )

Destroy the doca ct.

Description

Release all the resources used by doca ct.

Must be invoked before doca flow detroy.

__DOCA_EXPERIMENTAL int doca_ct_init ( const doca_ct_cfg* cfg )

Initialize the doca ct.

Parameters

cfg: CT configuration.

Returns

0 on success, a negative errno value otherwise.

Description

This is the global initialization function for doca ct. It initializes all resources used by doca flow.

Must be invoked first before any other function in this API. this is a one time call, used for doca ct initialization and global configurations.

Must be invoked after Doca Flow initilization, before port start.

__DOCA_EXPERIMENTAL int doca_flow_aging_handle ( doca_flow_port* port, uint16_t queue, uint64_t quota, doca_flow_aged_query* entries, int len )

Handle aging of flows in queue.

Parameters

port: Port to handle aging
queue: Queue identifier.
quota: Max time quota in micro seconds for this function to handle aging.
entries: User input entries array for the aged flows.

Description

Go over all flows and release aged flows from being tracked. The entries array will be filled with aged flows.

Since the number of flows can be very large, it can take a significant amount of time to go over all flows so this function is limited by time quota, which means it might return without handling all flows which requires the user to call it again. Once a full cycle is done this function will return -1.

__DOCA_EXPERIMENTAL void doca_flow_destroy ( void )

Destroy the doca flow.

Description

Release all the resources used by doca flow.

Must be invoked at the end of the application, before it exits.

Note:

This feature requires both a hardware and a software device to be available. Validated during context start.

doca_error_t doca_regex_set_hardware_compiled_rules ( doca_regex* regex, const void* rules_data, size_t rules_data_size )

Parameters

DOCA_ERROR_NO_MEMORY - Unable to allocate memory to store a copy of the rules.

Description

Specify the compiled rules data to be used by the hardware RegEx device.

Note:

This property is mutually exclusive with hardware un-compiled rules. This property mandates that a hardware device will be attached before the context is started. If no hardware device will be provided you should not specify hardware rules, or explicitly clear them by setting them to NULL. This will be validated as part of starting the context
The caller retains ownership of data pointed to by rules_data and is responsible for freeing it when they no longer require it. The engine will make a copy of this data for its own purposes.

doca_error_t doca_regex_set_hardware_uncompiled_rules ( doca_regex* regex, const void* rules_data, size_t rules_data_size )

Parameters

regex: The RegEx engine.
rules_data: An opaque blob of rules data which will be compiled by the engine into compiled rules data which is then provided to the hardware device.
rules_data_size: Size of the blob.

Returns

Description

Specify the un-compiled rules data to be used by the hardware RegEx device.

Note:

This property is mutually exclusive with hardware compiled rules. This property mandates that a hardware device will be attached before the context is started. If no hardware device will be provided you should not specify hardware rules, or explicitly clear them by setting them to NULL. This will be validated as part of starting the context
The caller retains ownership of data pointed to by rules_data and is responsible for freeing it when they no longer require it. The engine will make a copy of this data for its own purposes.
Rules compilation takes place during context start.

doca_error_t doca_regex_set_huge_job_emulation_overlap_size ( doca_regex* regex, uint16_t nb_overlap_bytes )

Parameters

regex: The RegEx engine.
nb_overlap_bytes: Number of bytes of overlap to use.

Returns

Description

Set the size of overlap to use when a job exceeds a devices maximum search size. Defaults to 0 (no overlap)

When a submitted job is larger than the receiving device can support it must be fragmented. This can cause issues if a match exists but is split across two fragments. To remedy this an overlap size can be set so that these matches may be detected. The overlap defined by this function specifies how many bytes of the previous search fragment will be resent as part of the next search fragment. So for example if a 100 byte job is submitted and a device supported a 32 byte maximum job length then the jobs sent would look as follows:

Overlap size First job Second Job Third Job Fourth job Fifth Job Sixth Job 0 [0-31] [32-63] [64-95] [96-99] --- --- 8 [0-31] [24-55] [42-79] [72-99] --- --- 16 [0-31] [16-47] [32-63] [48-79] [64-95] [80-99]

This allows the user to select an overlap value which provides enough overlap to detect any match they must find for the lowest cost.

Note:

The range of valid values for this property depend upon the device in use. This means that acceptance of a value through this API does not ensure the value is acceptable, this will be validated as part of starting the context

doca_error_t doca_regex_set_small_job_offload_threshold ( doca_regex* regex, uint16_t threshold )

Parameters

regex: The RegEx engine.
threshold: Threshold job size in bytes.

Returns

Description

Define a threshold for "small jobs". For scenarios where small jobs cause poor performance using the hardware RegEx device these can instead be redirected to the software device. Set this to a value > 0 to enable the feature. Set this value to 0 to disable the feature. Defaults to 0 (disabled)

Note:

This feature requires both a hardware and a software device to be available. The range of valid values for this property depend upon the device in use. This means that acceptance of a value through this API does not ensure the value is acceptable, this will be validated as part of starting the context

doca_error_t doca_regex_set_software_compiled_rules ( doca_regex* regex, const void* rules_data, size_t rules_data_size )

Parameters

Description

Copy the sha_partial session state from "from_session" to "to_session". This is useful if large amounts of data to be sha-calculated which share the same header segments, and only differ in the tail last few bytes. For example, we have two msgs: msg_0 = {header, tail_0}, msg_1 = {header, tail_1}, both of them need to be processed in sha_partial job.

when without session_copy functionality: we will do sha_calculation for msg_0 as: doca_sha_partial_session_create(ctx, workq, &session_0); doca_workq_submit(workq, &job_0_for_header); doca_workq_progress_retrieve(workq, &event, DOCA_WORKQ_RETRIEVE_FLAGS_NONE); doca_workq_submit(workq, &job_0_for_tail_0); doca_workq_progress_retrieve(workq, &event, DOCA_WORKQ_RETRIEVE_FLAGS_NONE); doca_sha_partial_session_destroy(ctx, workq, session_0); then, we will do sha_calculation for msg_1 as: doca_sha_partial_session_create(ctx, workq, &session_1); doca_workq_submit(workq, &job_1_for_header); doca_workq_progress_retrieve(workq, &event, DOCA_WORKQ_RETRIEVE_FLAGS_NONE); doca_workq_submit(workq, &job_1_for_tail_1); doca_workq_progress_retrieve(workq, &event, DOCA_WORKQ_RETRIEVE_FLAGS_NONE); doca_sha_partial_session_destroy(ctx, workq, session_1);

Obviously, the same data "header" is calculated twice!

when utilising the session_copy functionality, we will do sha_calculation for msg_0 as: doca_sha_partial_session_create(ctx, workq, &session_0); doca_workq_submit(workq, &job_0_for_header); doca_workq_progress_retrieve(workq, &event, DOCA_WORKQ_RETRIEVE_FLAGS_NONE); do a session_copy: doca_sha_partial_session_create(ctx, workq, &session_1); doca_sha_partial_session_copy(ctx, workq, session_0, session_1); continue to finish msg_0: doca_workq_submit(workq, &job_0_for_tail_0); doca_workq_progress_retrieve(workq, &event, DOCA_WORKQ_RETRIEVE_FLAGS_NONE); doca_sha_partial_session_destroy(ctx, workq, session_0); continue to finish msg_1: doca_workq_submit(workq, &job_1_for_tail_1); doca_workq_progress_retrieve(workq, &event, DOCA_WORKQ_RETRIEVE_FLAGS_NONE); doca_sha_partial_session_destroy(ctx, workq, session_1);

2.20. Telemetry Service Library

DOCA lib for exporting events to the telemetry service.

DOCA lib for exporting a netflow packet to a netflow collector through the telemetry service.

This lib simplifies and centralizes the formatting and exporting of netflow packets. Netflow is a protocol for exporting information about the device network flows to a netflow collector that will aggregate and analyze the data. After creating conf file and invoke init function, the lib send function can be called with netflow struct to send a netflow packet with the format to the collector of choice specified in the conf file. The lib uses the netflow protocol specified by cisco.

Limitations:

The lib supports the netflow V9 format. The lib is not thread safe.
