Generate an error when configured with a CNAME loop, rather than a crash. Thanks to George Metz for spotting this problem. Calculate the length of TFTP error reply packet correctly. This fixes a problem when the error message in a TFTP packet exceeds the arbitrary limit of 500 characters. The message was correctly truncated, but not the packet length, so extra data was appended. This is a possible security risk, since the extra data comes from a buffer which is also used for DNS, so that previous DNS queries or replies may be leaked. Fix logic error in Linux netlink code. This could cause dnsmasq to enter a tight loop on systems with a very large number of network interfaces. Fix problem with --dnssec-timestamp whereby receipt of SIGHUP would erroneously engage timestamp checking. Bump zone serial on reloading /etc/hosts and friends when providing authoritative DNS. Handle v4-mapped IPv6 addresses sanely in --synth-domain. These have standard representation like ::ffff:1.2.3.4 and are now converted to names like <prefix>--ffff-1-2-3-4.<domain> Handle binding upstream servers to an interface (--server=1.2.3.4@eth0) when the named interface is destroyed and recreated in the kernel. Allow wildcard CNAME records in authoritative zones. For example --cname=*.example.com,default.example.com more... |
