Doc Type:	Bug Fix
Doc Text:	Cause: snmpd, the Net-SNMP daemon, wrongly converted IPv4 addresses into network format on big-endian platform when processing UDP-MIB::udpTable. Consequence: Indices in the table were always '0.0.0.0' on big-endian platform, instead of real local IP address of UDP socket. Fix: The IP address is now converted correctly. Result: UDP-MIB::udpTable now contains local IP addresses as indices of the table.

Description Dalibor Pospíšil 2015-01-21 06:34:39 EST

Similar problem can be reproduced on RHEL5.4 on s390x.

after executing following command in the test 58:
# /usr/src/redhat/BUILD/net-snmp-5.3.2.2/apps/snmpnetstat/snmpnetstat -Cn -Cp udp -v2c -c testcommunity udp:localhost:8791

The output is searched for "127.0.0.1.8791" therefore it should be something like:

Active Internet (udp) Connections
Proto Local Address               
... excluded several lines with open udp ports ...
udp   127.0.0.1.123         
udp   127.0.0.1.8791        

but instead of it the output is:

Active Internet (udp) Connections
Proto Local Address               
... excluded several lines with open udp ports ...
udp   *:123         
udp   *:8791        

and therefore the test fails

58:testing if snmpnetstat finds the running agent in udpTable...FAIL


Version of the component:
net-snmp-5.7.2-20.el7.s390x

Comment 2 Jan Safranek 2015-06-18 05:49:12 EDT

This applies also to ppc64:

# snmpwalk localhost udpTable
...
UDP-MIB::udpLocalAddress.0.0.0.0.323 = IpAddress: 127.0.0.1
...

The IP address in the index (0.0.0.0) should be the same as the value (127.0.0.1).
