linux-ipsec: Re: ipnsec 0.82

I was using 2.0.32 and 2.0.33 with the Linux libc5.

The missing netlink.h is probably due to changes in 2.0.x to 2.1.x.

The __STUFF are probably caused by clash of kernel vs. GLibc definitions, or something nasty like that.

My priority is to get ipnsec up and running with proper kernel interface (ie. use firewalling hooks, rather than the ipsec0 device) under at least one environment, rather than to make the code running in every possible environment. In this respect, please consider the whole ipnsec development branch as an experimental alpha quality code.

It works for me under 2.0.33 using (changed) RedHat 4.2 system (and is known to run and compile under RedHat 4.1 as well).

If you have some interesting project and strict dependency on the 2.1 kernel or GLIBC, please let me know and I will try to fix it.

Do you need help?

On the other hand, the quality of the code and docs is as bad today, that users are supposed to be able to fix at least the missing header files themselves.

Sorry if this does not help you.
