https://bugzilla.kernel.org/show_bug.cgi?id=17622
Summary: snmp trap ALG issue
Product: Networking
Version: 2.5
Kernel Version: 2.6.35.4
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: IPV4
AssignedTo: shemminger@linux-foundation.org
ReportedBy: wtweeker@163.com
Regression: No
Symptom:
SNMP manager can't show trap when SNMP agent set trap message to version1.
steps to reproduce:
(1)SNMP agent-----linux device(NAT)-----SNMP manager.
(2)Set SNMP agent trap message to version 1, destination IP as SNMP manger's
IP.
(3)Do some operation to generate trap message, such as make one port of SNMP
agent up and down. But SNMP manger can't accept trap message.
I have capured the packet by Ethereal software, and check the SNMP trap packet,
found that the UDP checksum is incorrect.
I think that the function fast_csum()(nf_nat_snmp_basic.c) have some problem.
