I don't really have much involvement in this, but anytime you can simplify you're ahead.

Well, it is simple. I made a branch and removed nss in that:

We could merge the branch, if we decide to go into that direction.

Hi, as long as it is "that simple" I agree with you. We should try to reduce overhead as much as possbile an concentrate on things which are more important.

Hello,
I think it is time to discuss a thing, that has been stuck in my head for some time now: We have too many SSL implementations in the system. And as we are already discussion what we can remove from the distribution (Xen), I'd like to think about the SSL libraries.
IPFire 3 comes with openssl, GnuTLS, nss and polarssl. They all basically implement the same protocols, but they differ a bit in their interfaces, so a lot of projects prefer the one or an other.
When we had the Lucky Thirteen problem last week, I had to patch all four libraries. That's redundant work and I don't see any sense in that. I even see this as a security issue, because it is not easy to keep track of security issues in all libraries.
I would like to think about how we can get rid of some of these libraries:
openssl We cannot get rid of this one because openssl is widely used and I tend to think that it is the de-facto standard library. A bit of a problem is the GPL-incompatible license.
GnuTLS This is a much better choice in terms of licenses and GnuTLS is also widely used. I'd like to keep it.
nss The reason we have this is that RedHat started to move a lot of their own software to it because nss is FIPS certified. However, this certification is not important to us at this point in time and nss is only used by glibc, apr-util and curl. All of them could be compiler either without nss or with an other SSL library.
polarssl This library came into the distribution very recently and is used by the authoritative powerdns server. As far as I am aware, powerdns cannot use any other library.
Conclusively, we can't (or don't want) to get rid of openssl, GnuTLS and polarssl. But nss looks like a candidate for me. Opinions?
