2017-10-30udp_io, traceroute: Standardise IPv6 PKTINFO handling to be portableJames Clarke
The current standard (RFC 3542) is for IPV6_RECVPKTINFO to be given to setsockopt, and IPV6_PKTINFO to be used as the packet type. Previously, RFC 2292 required IPV6_PKTINFO to be used for both, but RFC 3542 re-purposed IPV6_PKTINFO when given to setsockopt. The special Linux-specific IPV6_2292PKTINFO has the same semantics as IPV6_PKTINFO in RFC 2292, but was introduced at the same time as IPV6_RECVPKTINFO. Therefore, if we have IPV6_RECVPKTINFO available, we can use the RFC 3542 style, and if not, we assume that only the RFC 2292 API is available, using IPV6_PKTINFO for both.

2008-05-22dnsd: fixes various segfaults.Denis Vlasenko
One was a lib api change that was not updated and another is a stack buffer overflow. It also adds support for '*' in dnsd.conf. It resolves all hostnames to a specific ip address. This is useful if you for example want redirect all http traffic to your first-boot-web-wizard on you router/firewall. By Timo Teras
