Hey Adrian,
I just looked at that
cupsys-1.1.15/config-scripts/cups-openssl.m4 and I find no mention of
GnuTLS in there at all. Then I took at look at debian/rules and
noticed that cupsys isn't even built with SSL or TLS enabled.
./configure --with-optim=$(DEB_OPTFLAGS) \
--with-cups-group=lpadmin --mandir=/usr/share/man \
--with-docdir=/usr/share/cups/doc-root --disable-ssl --enable-slp
So this leaves me with a few problems.
1. I still don't know what steps are neccessary to convert an OpenSSL
program into one that uses GnuTLS for encryption.
2. Until #16748 - cupsys needs a "Build-Conflicts: libssl-dev" is
resolved, any cupsys-pt client will have no encrypted CUPS server
in Debian to talk to.
But...
----------------------------------------------------------------------
Exhibit A
<http://www.openssl.org/support/faq.cgi#LEGAL2> states:
2. Can I use OpenSSL with GPL software?
If you develop open source software that uses OpenSSL, you may
find it useful to choose an other license than the GPL, or state
explicitly that "This program is released under the GPL with the
additional exemption that compiling, linking, and/or using OpenSSL is
allowed." If you are using GPL software developed by others, you may
want to ask the copyright holder for permission to use their software
with OpenSSL.
----------------------------------------------------------------------
Exhibit B
<http://www.cups.org/faq0004.html>
In addition, as the copyright holder of CUPS, Easy Software Products
grants the following special exceptions:
2. OpenSSL Toolkit License Exception;
a. Easy Software Products explicitly allows the compilation
and distribution of the CUPS software with the OpenSSL
Toolkit.
----------------------------------------------------------------------
From my understanding of the above two clauses, cupsys can be
built with OpenSSL support enabled. So why is it explicitly disabled
at the moment? Why do you call for GnuTLS support for cupsys in
#167489? What is the official debian-legal position on this because
I'm really, really confused now...
Yours sincerely,
Andrew "Netsnipe" Lau
