Fuzzing CoAP adheres to the same principles as MQTT presented previously, but has some twists and turns that call for some explanation.

First of all, the "delta" encoding of option_delta and option_length cannot be handled by RAW as of today, so a
new protocol module has been written based on RAW which can handle the encoding direction only and this should be sufficient for fuzzing,
assuming that decoding is done with the legacy (handwritten) decoder.


However, the structures declared in CoAP_Types.ttcn and in CoAP_FTypes.ttcn are different: the first ones are optimized for easiness of use,
while the second ones to enable fuzzing.

Let's call structures in CoAP_Types "Internal" and those in the CoAP_FTypes "external".

For instance a confirmable GET expressed in the first approach ("Internal") looks like this:

template CoAP_Types.CoAP_ReqResp t_client_TD_COAP_CORE_01_req00 :=
{
  header := 
  {
    version := 1,
    msg_type := CONFIRMABLE,
    code := CoAP_Types.METHOD_GET,
    message_id := 0
  },
  token := 'ABCDEF11'O,
  options := 
  {
    {
      uri_path := "test"
    }
  },
  payload := omit
}



but the equivalent one described with the second approach ("External") like this:

template CoAP_FTypes.CoAP_MessageExt t_ext_err_client_TD_COAP_CORE_01_req00 :=
{msg:=
  {

    version := 1,
    msg_type :=  CONFIRMABLE,
    tkl := 0,
    code := {
      class := 0,
      detail := 1
    },
    message_id := 0,

    token := 'ABCDEF11'O,
    options := {
      {
        option_delta := 11,
        option_length := 4,
        option_delta_ext := omit,
        option_length_ext := omit,
        option_value :='74657374'O
      }
    },
    payload := {
      payloadMarker := 'FF'O,
      payload := 'AA'O 
    }
  }
}	
  


The first one is more user friendly, but misses a number of fields that are automatically calculated by the handwritten encoder which are of interest
for fuzzing hence made visible in the second set of structures.


The recommended workflow then is to write some "master" templates based on the "internal" types and convert them into "external" types using
f_CoAPInternalToExternal():


index.php/fa/28992/0/


Note: "Internal" templates will have to be written with the options in increasing order of option number, then converted to "External" templates (else conversion will result in an error).
"External" types then can be fuzzed using the technique presented.


Otherwise , the messaging architecture defaults to the second scenario presented in the introduction, with separate paths for encoding and decoding.
Again, nothing else but an initial confirmable GET is fuzzed:

As it can be seen from the log file, some of these GET messages are acknowledged, but some not.

Hi Elemer Lelik,

Thank You in Advance!

With Regards,

Hi Avdoot,

as I mentioned in the first part of the series
Using Titan as a fuzzing engine part 1
https://www.eclipse.org/forums/index.php/t/1085150/

this is a brand new feature added only in post 6.1.0 releases of Titan;
please build the latest Titan from source as per instructions in github/README.linux

I hope this helps

Best regards

Elemer

Hi Elemer Lelik,
I performed all the steps given in README.linux

But still it gives me this error.

Hi Avdoot,

from your log
:
Product number: CRL 113 200/6 R1A
Build date: Mar 28 2017 09:40:44
:

it appears that you don't have the latest source code,
you have built your Titan on the 28th of March;

you need to download the latest source and build from there.
you should see Product number: CRL 113 200/6 R1B returned by "compiler -v"

BR

Elemer
