Description Henrik Nordstrom 2008-06-18 14:23:55 EDT
Description of problem:

snmpget of a counter32 variable having a value of 0xFFFF0000 results in a
warning "truncating unsigned value to 32 bits (2)".

Version-Release number of selected component (if applicable):


How reproducible:

Each time querying for a SNMP variable with a value > 2^31.

Steps to Reproduce:

No simple test case created yet.

1. Set up an SNMP agent having a Counter32 variable with a value > 2^31.
2. snmpget of that variable
Actual results:

snmpget prints the above warning, and outputs the correct result.

Expected results:

No warning unless the integer was ASN encoded using more than 4 bytes.

Additional info:

The value was ASN encoded using 3 bytes (24 bits). The error is most likely from
sign extension, which is done on all ASN.1 encoded integers.
Comment 1 Henrik Nordstrom 2008-06-18 14:32:03 EDT
On a second thought it may be an agent error.. it's better if the value is
encoded  using 5 bytes


to prevent sign extension, and gets rid of the warning.

So it's not a bug. Gone.
