[sr-dev] ims_diameter_server and cdp modules modification

[Maryam Baghdadi]

Hello,

I used from kamailio with MMTel features as AS in my IMS scenario and I
wanted to send UDR diameter request from AS to my HSS. According to my
study I should use "diameter_request" or "diameter_request_async" in
ims_diameter_server module . but some problem exists in diameter_request
function which caused "json" string as input of "diameter_request" ignored
and fault happened.
I added parse and checking "json" string in diameter_request function in
ims_diameter_server.c file :

      if (message) {
                if (get_str_fparam(&s_message, msg, (fparam_t*)message) <
0) {
                    LM_ERR("failed to get json string\n");
                    return -1;
                }
                LM_DBG("json %.*s\n", s_message.len, s_message.s);
        }


 also cdp_get_session function in cdp module has problem with "lock and
unlock session" and   " AAASessionsLock(hash);
" doesn't work correctly.  I comment " AAASessionsLock(hash);"  and  "
 AAASessionsUnlock(hash);"

I recompiled ims_diameter_server and cdp modules again

called below part in request_route of my configuration :

 if(is_method("REGISTER"))
        {
       diameter_request("hss domain address", "16777217", "306", "{
'avpCode':263 , ....}");
        }
this worked correctly and UDR request sent to hss .
