[Kea-users] Kea 3.2.0 DHCP_RECEIVE4_UNKNOWN Warnings

[isc-mailing-list at secmail.8shield.net]

Hello,

After upgrading from 3.0.3 to 3.2.0 I started seeing the following warning in my logs:

Jun 24 22:40:21 dns01.redacted.net kea-dhcp4[769057]: WARN DHCP_RECEIVE4_UNKNOWN Received data over unknown socket
Jun 24 22:40:21 dns01.redacted.net kea-dhcp4[769057]: WARN DHCP_RECEIVE4_UNKNOWN Received data over unknown socket

...

It appears that the warning is triggered by the Stork Agent connection. The "control-sockets", "loggers" and the Stork Agent configurations did not change between versions:

...
"control-sockets": [
{
"socket-type": "http",
"socket-address": "127.0.0.1",
"socket-port": 8000,
"authentication": {
"type": "basic",
"realm": "kea-dhcpv4-server",
"directory": "/etc/kea/auth",
"clients": [
{
"user-file": "stork-agent.user",
"password-file": "stork-agent.passwd"
}
]
}
},...

"loggers": [
{ "name": "kea-dhcp4",
"severity": "WARN",
"debuglevel": 0,
"output-options": [ { "output": "stdout", "pattern": "%-5p %m\n" } ]
},
{
"name": "kea-dhcp4.bad-packets",
"severity": "INFO",
"output-options": [
{
"output": "/var/log/kea/kea-dhcp4.bad-packets.log",
"pattern": "%D{%Y-%m-%d %H:%M:%S.%q} %-5p %m\n",
"maxsize": 10240000,
"maxver": 5
}
...

The only way I was able to silence the warning while keeping the "kea-dhcp4" in WARN was to add the following to loggers:

{
"name": "dhcp",
"severity": "ERROR"
},
Is this "new" behaviour expected or is there something else amiss in my configuration for v3.2.0?

Thanks,
Mathieu.
