IPv6 and IPSEC

+ +The IPv6 support patches are really more protocol-family independence +patches. Because of this, in most places, "ports" (numbers) have been +replaced with "services" (strings, that may be digits). This allows us +to run with certain protocols that use strings as "service names" +where we in the IP world think of port numbers. Someday we'll plumb +strings all over and then, if inet6 is not enabled, do a +getservbyname() down in SocketOpen. The IPv6 support patches use +getaddrinfo(), which is a POSIX p1003.1g mandated function. So, in the +not too distant future, we'll zap the ifdefs and just let autoconf +check for getaddrinfo. IPv6 support comes pretty much automatically +once you have protocol family independence.

+ +Craig Metz used his inner_connect() function to handle most of the +connect work. This is a nonstandard function not likely to ever exist +in a system's libc, but we can just include that source file if the +day comes when we want to support IPv6 without the inet6-apps +library. It just makes life easier.
