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.
Add a struct with multiple dns file descriptors (for IPv4 and IPv6)
and pass this to required areas. Choose which descriptor to use when
sending by looking at the destination address family.
"Permission to use, copy, modify, and distribute this software" is now
"Permission to use, copy, modify, and/or distribute this software".
Add license header to source files missing one.
The client could bypass the password check by continuing after getting error
from the server and guessing the network parameters. The server would still
accept the rest of the setup and also network traffic.
Add checks for normal and raw mode that user has authenticated before allowing
any other communication.
Problem found by Oscar Reparaz.
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.
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.
iodined.c: In function ‘write_dns_nameenc’:
iodined.c:2030:23: attention : argument to ‘sizeof’ in ‘memset’ call is the same
expression as the destination; did you mean to provide an explicit length? [-Wsizeof-pointer-memaccess]
memset(buf, 0, sizeof(buf));
sizeof buf will just give the size of the pointer, while buflen will clean the whole
memory.
