This time I have a little bit more controversal patches. But I think still useful. They fixes memory leaks that might occur in some cases. Most dnsmasq errors is fatal, so it does not matter. But some are not. Some parts are reloaded on SIGHUP signal, so it might leak more than once. Some example when it changes the failures. Use dhcp-options file with this content: tag:error,vendor:redhat option:ntp-server,1.2.3.4.5 option6:ntp-server,[:::] Is not fatal and dnsmasq will start. On each reload command, it would leak some memory. I validated it using valgrind --leak-check=full dnsmasq -d. This patch fixes it. It introduces something that might be considered constructor and destructor of selected structures.
