We would appreciate a patch in unified diff format.

In snmp.c, one cannot use the OIDSIZE macro for the
usmAES128PrivProtocol symbol because it is defined as a oid pointer to
usmAESPrivProtocol, not an oid array.
The fix is to change all OIDSIZE(usmAES128PrivProtocol) expressions to
USM_PRIV_PROTO_AES_LEN.
This is with net-snmp; not sure about ucd-snmp.

Description:
------------
A bug in the source of php-snmp causes use of AES privacy encryption
impossible.
Reproduce code:
---------------
//Assuming snmpd is configured appropriately for the user
$result = snmp3_walk("localhost", "user", "authPriv", "sha",
"passphrase", "AES", "passphrase", "system", 1000000, 10);
print_r($result);
Expected result:
----------------
//The output of the system OID
Array
(
[0] => STRING: Linux smoynes 2.6.11.4-21.10-smp #1 SMP Tue Nov 29
14:32:49 UTC 2005 i686
...
)
Actual result:
--------------
PHP Warning: %v%v(): An error occurred, quitting in aes_test.php on
line 3
