Hello Christoph,
Hey, that's great news. It looks like you were able to make it work with a
very small patch.
A couple comments:
(1) The TYPE_SOCKLEN_T macro is cool, but we can't rely on people having
autoconf 2.5 or newer (unless we start distributing configure in addition to
configure.in). Is there a way the macro could be coded to eliminate this
dependency? What is it in the macro that requires 2.5?
(2) You might want to take a look at 1.1.1.9 which is on the CVS now. In
particular, tun.c has seen a lot of work over the weekend to add support for
solaris, freebsd, and openbsd. You will want to add an #ifdef TARGET_DARWIN
to the mix. You might also want to add a TARGET_DARWIN case to
do_ifconfig(), so OpenVPN's --ifconfig option works correctly on Mac OS X.
Can you edit INSTALL with the appropriate Mac OS X info, including a URL
where they can get your tun driver, and initial steps to create and
configure the tun device?
I will merge everything in your patch now except the TYPE_SOCKLEN_T macro
pending more thought.
Great Work!
James
