[netflow-tools] A small bug

[章晋学]

Dear Mr. Miller,

         When I ran flowd-0.9 in my Sparc64 box, I found that when a v9
template arrives, the same DEBUG info will show:

                   “short netflow v.9 flowset  template
0x00000011/0x00000104 88 bytes from *.*.*.*”, so I can’t receive data
flowsets

         It is abnormal because I can receive netflow v9 data in my 32-bits
box by flowd-0.9.  Through debugging, I think the 883th line in flowd.c
maybe incorrect since “tmplr” is a pointer or address. 

So

sizeof(tmplr)= 4 in 32-bits box;

                     =8 in 64-bits box;

 

When I rewrite it as sizeof(*tmplr), it work normally both in 32-bits and
64-bits box.

 

 

    879                         tmplr = (struct NF9_TEMPLATE_FLOWSET_RECORD
*)

    880                             (pkt + offset);

    881                         recs[i].type = ntohs(tmplr->type);

    882                         recs[i].len = ntohs(tmplr->length);

    883                         offset += sizeof(tmplr);

    884 #ifdef DEBUG_NF9

    885                         logit(LOG_DEBUG, "  record %d: type %d len
%d",

    886                             i, recs[i].type, recs[i].len);

887 #endif

 

 

 
Best wishes
