net-snmp crash

[Michael W. Lucas]

Hi,

I can reliably crash net-snmp with an snmpset. Worth a formal bug
report?

$ uname -a
FreeBSD freebsdtest 12.0-RELEASE-p10 FreeBSD 12.0-RELEASE-p10 GENERIC  amd64

$ pkg info net-snmp
net-snmp-5.7.3_20,1
Name           : net-snmp
Version        : 5.7.3_20,1
Installed on   : Wed Oct  9 15:22:24 2019 EDT
...

Detail:

$ sysctl net.inet.ip.forwarding
net.inet.ip.forwarding: 0

$ snmpget freebsd IP-MIB::ipForwarding.0
IP-MIB::ipForwarding.0 = INTEGER: notForwarding(2)

$ snmpset freebsd IP-MIB::ipForwarding.0 i 1
Timeout: No Response from freebsd

Yep, the agent is dead:

$ pgrep snmpd
$

The sysctl change took place, however:

$ sysctl net.inet.ip.forwarding
net.inet.ip.forwarding: 1

I can restart the agent and reverse the change, but snmpd crashes
again.

So: worth a bug report, or no?

==ml
