Net-snmp returns zeros for various UDP and TCP mibII data


While testing out the latest net-snmp bits, I noticed that various TCP and UDP mibII OIDs would continuosly display zeros on my Solaris 10 update 6 host:

$ snmpwalk -c ... -v 2c localhost udpInDatagrams.0

UDP-MIB::udpInDatagrams.0 = Counter32: 0

Generate lots of UDP traffic.

$ snmpwalk -c ... -v 2c localhost udpInDatagrams.0

UDP-MIB::udpInDatagrams.0 = Counter32: 0

This turns out to be caused by a net-snmp bug, which is fixed by applying the patch attached to the bug report. I am posting this here to help others who may bump into this issue.
