Hi,
I inadvertently left a “tag:” off a “dhcp-boot=“ line which resulted in dnsmasq crashing.
This was the line that caused Dnsmasq to crash:
dhcp-boot=tag:ww3001,UEFI,/ipxe.efi,10.109.0.1,10.109.0.1
The line was supposed to be:
dhcp-boot=tag:ww3001,tag:UEFI,/ipxe.efi,10.109.0.1,10.109.0.1
We are using 2.82 in production where the crash doesn’t happen until a matching packet arrives.
But I did also try 2.85 before submitting this report and it crashes whilst parsing the configuration file:
# /tmp/dnsmasq-2.85/src/dnsmasq -k -p0
Segmentation fault
