Segmentation fault using REST API in DHCPv4 HA setting
Hi,
This issue has been reported in the kea-users mailing list yesterday and Andrei Pavel asked to create an issue here with a few extra details.
I am trying to configure a pair of kea servers running in high availability mode. However, the servers crash with segfault when I try to use the HTTP RESP API for some commands. I figured out how to reproduce the problem in one situation described below.
The server is a Ubuntu 22.04 LTS, running kea 2.2.0 from the repository https://dl.cloudsmith.io/public/isc/kea-2-2/deb/ubuntu jammy main.
The server is a Xen VM with 2GB of RAM, kernel 5.15.0-43-generic #46-Ubuntu SMP and glibc 2.35.
This following python script loads a configuration file and calls config-set using the HTTP API.
#!/usr/bin/python3
#coding: utf-8
import json, requests
with open('bug-config.json') as f:
config = json.load(f)
url = 'http://192.168.89.12:8000/'
headers = {'content-type': 'application/json'}
payload = {}
payload['command'] = 'config-set'
payload['service'] = [ 'dhcp4' ]
payload['arguments'] = config
res = requests.post(url, headers=headers, data=json.dumps(payload))
response = res.json()[0]
print('Set config: ' + response['text'])The configuration file sent using the API is this one, without the shared-networks section. The problem also happens when I send a complete configuration, but this small one is enough to reproduce the problem. The configuration file running in the server when I send the config-set is the same, but has about 19000 host reservations identified by the hw-address, distributed in 180 networks that are in 90 shared-networks.
