FS#186 - Kamailio 3.2.1 Dialog Crash

I had a similar problem, in "dlg_handlers.c", function "dlg_get_msg_dialog":

  dlg = get_dlg(&callid, &ftag, &ttag, NULL);

so "NULL" for direction... and in file "dlg_hash.h", function "match_dialog":

 if (*dir==DLG_DIR_DOWNSTREAM) {

but dir is NULL...

I changed "dlg_handlers.c", function "dlg_get_msg_dialog" to:


dlg_cell_t *dlg_get_msg_dialog(sip_msg_t *msg)
{
        dlg_cell_t *dlg = NULL;
        str callid;
    str ftag;
    str ttag;
        unsigned int dir = DLG_DIR_NONE;

        /* Retrieve the current dialog */
        dlg = dlg_get_ctx_dialog();
        if(dlg!=NULL)
                return dlg;

        if (pre_match_parse(msg, &callid, &ftag, &ttag, 0)<0)
                return NULL;
        dlg = get_dlg(&callid, &ftag, &ttag, &dir);
        if (dlg==NULL){
                LM_DBG("dlg with callid '%.*s' not found\n",
                                msg->callid->body.len, msg->callid->body.s);
                return NULL;
        }
        return dlg;
}


and it seems to work now...
