2018-05-13Improve ipfix template packet rewrite constructionDave Barach4-10/+127
Instead of repeatedly cutting, pasting, and hacking to create a new callback, use vnet_flow_rewrite_generic_callback(). Add three arguments to the flow rewrite callback: (in) pointer to an array of report elements, (in) length of array, (out) pointer to the stream index Change existing code prototypes. Code owners encouraged to evaluate whether they can use the generic callback or not, at leisure. /* ipfix field definitions for a particular report */ typedef struct { u32 info_element; u32 size; } ipfix_report_element_t; Best generated like so: _(sourceIPv4Address, 4) \ _(destinationIPv4Address, 4) \ _(sourceTransportPort, 2) \ _(destinationTransportPort, 2) \ _(protocolIdentifier, 1) \ _(flowStartMicroseconds, 8) \ _(flowEndMicroseconds, 8) static ipfix_report_element_t simple_report_elements[] = { foreach_simple_report_ipfix_element }; ... /* Set up the ipfix report */ memset (&a, 0, sizeof (a)); a.is_add = 1 /* to enable the report */ ; a.domain_id = 1 /* pick a domain ID */ ; a.src_port = UDP_DST_PORT_ipfix /* src port for reports */ ; a.rewrite_callback = vnet_flow_rewrite_generic_callback; a.report_elements = simple_report_elements; a.n_report_elements = ARRAY_LEN (simple_report_elements); a.stream_indexp = &jim->stream_index; a.flow_data_callback = simple_flow_data_callback; /* Create the report */ rv = vnet_flow_report_add_del (frm, &a, &template_id); if (rv) return rv; ...
