Use %U and unformat_udp_port instead of %u for unformat() call for
u16 collector_port number in set_ipfix_exporter_command_fn() to
avoid corruption of other variables which can happen if unformat()
with %u is used with a 16-bit variable. This avoids crash due to
corrupted fib_index value.

The vlib init function subsystem now supports a mix of procedural and
formally-specified ordering constraints. We should eliminate procedural
knowledge wherever possible.
The following schemes are *roughly* equivalent:
static clib_error_t *init_runs_first (vlib_main_t *vm)
{
clib_error_t *error;
... do some stuff...
if ((error = vlib_call_init_function (init_runs_next)))
return error;
...
}
VLIB_INIT_FUNCTION (init_runs_first);
and
static clib_error_t *init_runs_first (vlib_main_t *vm)
{
... do some stuff...
}
VLIB_INIT_FUNCTION (init_runs_first) =
{
.runs_before = VLIB_INITS("init_runs_next"),
};
The first form will [most likely] call "init_runs_next" on the
spot. The second form means that "init_runs_first" runs before
"init_runs_next," possibly much earlier in the sequence.
Please DO NOT construct sets of init functions where A before B
actually means A *right before* B. It's not necessary - simply combine
A and B - and it leads to hugely annoying debugging exercises when
trying to switch from ad-hoc procedural ordering constraints to formal
ordering constraints.

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;
