RE: Can parse_oid_indexes() parse fixed-length string indexes?

It looks like the ASN_PRIV_IMPLIED_OCTET_STR switch case, assumes that
the rest of the instance is the fixed length string (and it does not
look for a preceeding string length component).

But what if the instance includes some other index type after this
fix-length string?
(It implies that the parsing mechanism MUST have the pre-defined length
of a fix-length string.)


By the way:
-----------------
I saw something that looks like a bug:
In the parse_one_oid_index() function (Net-SNMP 5.3.0.1):

*********************************************
if (uitmp > (int) (*oidLen)) {
                for (i = 0; i < *oidLen; ++i)
                    var->val.string[i] = (u_char) * oidIndex++;
                for (i = 0; i < uitmp; ++i)                 // Erez
Makavy: Is this a BUG?!!!
                    var->val.string[i] = '\0';
                (*oidLen) = 0;
            } else {
***********************************************

In this if cluase, the first 'for' startement is overridden by the
second 'for' statement.
(val.string, will always be set to all zeros)

Using a var of type ASN_PRIV_IMPLIED_OCTET_STR will force it to be a
fixed length string.
