Erik Ekman d0fb85e8cf Do not use 53 as source port for DNS/raw traffic. 
For some reason this makes raw traffic get dropped.

Erik Ekman 5b71224def Fix segfault in windows tun reader thread 
The arguments to open_dns() needs to be updated after API change.
Called with 0, INADDR_ANY used to mean port, IP address but now means
pointer to sockadddr and its length. Thanks to C for not giving any
warnings or errors..

Barak A. Pearlmutter 88590bcaaf Mixing signed and unsigned quantities in MIN() upset GCC's tender soul. 2014-04-06 13:41:31 +02:00
Barak A. Pearlmutter f73fb9f8d0 rewrite comparison to avoid negative unsigned numbers 
Note that GCC -O2 is happy to optimize away (x<0) when x is an
unsigned quantity.  This was actually occurring in CHECKLEN(0),
causing the compiler to issue a warning.

Erik Ekman 400f45c793 Do not use AI_ADDRCONFIG on Windows 
It was not available on my MinGW crosscompiler,

Also, remove old conflicting WINVER in osflags.
It is set in src/windows.h now.

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.

Add socket activation for systemd, with a option to stop on idle
 2014-01-29 09:25:00 -08:00
Michael Scherer abd276ed9e Add idle option, so we can stop iodine and start it on demand with systemd 2013-12-23 22:57:50 +01:00
Michael Scherer 27fb4c75cd Add support to have on demand socket activation of iodine 2013-12-23 22:57:40 +01:00
Michael Scherer 64ff684754 Fix gcc warning -Wsizeof-pointer-memaccess 
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.
