[Dnsmasq-discuss] Segfault during startup when using incorrect dhcp-relay values

[Knodt, Florian]

Hi,

when starting dnsmasq with a config file containing an invalid
dhcp-relay statement a segfault occurs during startup. I could observe
this with Debians bundeled 2.76-5+deb9u2 as well as manually compiled
2.76-2.80.

---snip---

/etc/dnsmasq.conf

dhcp-relay=10.10.10.1
