[debian-mysql] Bug#761911: Bug#761911: mariadb-server-core-5.5: MariaDB lacks documentation of OpenSSL exception to GPL

[Otto Kekäläinen]

I've read up on pages like
https://people.gnome.org/~markmc/openssl-and-the-gpl.html and
https://www.openssl.org/support/faq.html#LEGAL2. Getting a permission
statement for a GPL-OpenSSL exception (which basically is only needed
for Debian as others don't interpret GPL in such a strict way) from
all of MariaDB/MySQL copyright holders is an impossible task for a
packager like me.

For 10.0 I've now switched using the bundled YaSSL in commit
http://anonscm.debian.org/cgit/pkg-mysql/mariadb-10.0.git/commit/?id=477bad781a9338ff6542d71c78432b387dedb05f
and so far builds and tests suites have passed OK. If Debian starts to
ship YaSSL as a package we could start to rely on a distro provided
build dependency, or if CYaSSL develops to be on par with YaSSL in
terms of OpenSSL API compatibility and upstream MariaDB would adopt
their fork to it, we in Debian could also switch to CYaSSL and benefit
of using a distro packaged build dependency. Until then, the bundled
YaSSL is our solution. The same applies also for the Debian MySQL
packages.
