Ralf Ramsauer 1c86bf347f iodine/iodined: do not print usage if no superuser
There is no value in printing the usage in this case, as the usage
doesn't give the user any hint on how to solve this issue.

Furthermore, replace the Windows implementation with an empty inline
function, which will result in no code.

Erik Ekman fc1611fc40 Only accept IPv6 in server IPv6 socket
Set IPV6_V6ONLY flag on server socket. Not all operating systems
support mixing v4/v6 in one socket, so separate them all the time.

Erik Ekman b4e9148df8 Support raw mode for both IPv4 and IPv6
Read destination address of IP request packet and return it.
Check length in client and use it as IPv4 or v6 depending on length.

Erik Ekman 7a117bd71e IPv6 support for DNS traffic in server
Server will by default listen on both IPv4 and IPv6.
No way to only listen on one protocol right now.

Use -L to only listen on a specific v6 address.

IP address to use for raw mode is still IPv4 only.
Use -n on server to make raw mode work from IPv6 clients,
then they will get an IPv4 address from the server for raw mode.

Tunnel data is still IPv4.

Erik Ekman 3ebcd29b13 Add support for using an unspecified RR type
Add PRIVATE query type with id 65399 (private use range).
According to RFC3597 the reply data in a query with unspecified RR type must be handled
as unstructured binary data, which means it can contain raw packet data just like the NULL type.
Since the reply format is optimal it is ordered just after NULL in the priority order.

Erik Ekman f02339b3b2 IPv6: Create single way to format IP addresses 2014-02-06 19:44:26 +01:00
Erik Ekman a1d88c4f0a IPv6 support for client (#107)
The iodine client now supports both IPv4 and IPv6 nameservers for
sending DNS queries to an IPv4 iodined. The nameserver will
transparently handle translation between IP protocols.

Windows port needs Vista or later to support IPv6.
