Hi,
Thanks to Faidon, we've got an issue [1] tracking the work of getting
radsecproxy to work with OpenSSL 1.1.
[1] https://project.nordu.net/browse/RADSECPROXY-66
The questions now are 1) does the proposed patch work for you and 2) how
little backwards compatibility can we get away with?
If you're a radsecproxy user, what version(s) of OpenSSL do you really
need support for?
If you know how to build radsecproxy from source, please test the
'openssl11' branch [2] with OpenSSL 1.1.0 and let us know if it works
for you.
[2] git clone -b openssl11 https://git.nordu.net/radsecproxy.git
Thanks,
Linus

I'm maintaining a radsecproxy package for OpenWRT/LEDE which runs
openssl 1.0.2h. Keeping compatibility with that would be nice :)

Well, it compiles on openwrt at least (or rather, the master branch
does). However, pulling in two crypto libraries on an embedded platform
is not ideal. Would it be feasible to drop openssl entirely in favour of
libnettle? Or maybe something like mbedtls (formerly polarssl;

Don't have a setup that'll let me test running right now... Will see if
I can get one setup...

What are the issues with two libraries? Size? Assuming you're linking
statically I wouldn't expect the few libnettle functions to be too
expensive. But I haven't checked closely.
Nettle does crypto stuff but no TLS so something like mbedtls or any of
the other TLS libraries would indeed be needed. Depending on their API,
they might be more or less complicated to use as a drop in replacement
for OpenSSL. Please let me know if you get something working (but I have
to admit that I'm not overly eager on supporting another TLS library.)
And oh, beware of the multithreaded nature of this program!

Sure, on a number of TP-Link APs. Works like a charm for "mobile" eduroam. If it

Well, the LEDE/OpenWrt people are doing a great job of building a modern
Linux distro (including dynamic linking :)) that fits in a couple of
megabytes of flash. One of the ways of achieving that is asking for
basically every change: What is the image size impact?
And the nice thing about using radsecproxy on such a device is that it
means you can offload all the user authentication to one of those
"server" thingies. I'm not sure how many people actually use the
radsecproxy package, but someone contributed scripts to generate
configuration from the platform-specific configuration language. So I
guess someone is finding it useful :)
