Description Josef Ridky 2019-02-07 08:08:33 UTC

Description of problem:
In IPv6, snmp trap packet does not send from specified interface assigned by clientaddr option in snmp.conf

Version-Release number of selected component (if applicable):
net-snmp-5.8-6.el8

How reproducible:
Always

Steps to Reproduce:
1. Prepare two nics for the server.
2. Assign IPv6 address to two NICs.
3. Assigned clientaddr to /etc/snmp/snmp.conf
~~~
clientaddr 2001:db4::101
~~~
4. Send snmp trap to another server.
5. Check source address in the packet.

Actual results:
The source address is not the assigned address.

Expected results:
The source address is the assigned address in clientaddr option.

Additional info:
Wrong condition in file snmplib/transports/snmpUDPIPv6Domain.c function netsnmp_udp6_transport:
if(!netsnmp_sockaddr_in6_2(&client_addr, client_socket, NULL))

because netsnmp_sockaddr_in6_2 function returns 0 if an error and 1 if successfully resolved as we can see in snmplib/transports/snmpIPv6BaseDomain.c
