Hi,

Reprising this old bug, it's a shame that a good security hardening
extension for PHP was kept out of Debian for two releases.

I think this turns out to be a different situation than other packages
(where things unrelated to PHP code had been put under the PHP license,
therefore not being able to satisfy the license terms).

In the upstream bug[0] it is claimed by the author:
"Suhosin incorporates some PHP Code directly"
and that they can't relicense Suhosin because of that.

But does that mean Suhosin has fully complied with the license?

Suhosin retains the same license.

I don't think that was at issue, if the product is called "Suhosin".

Suhosin hasn't modified the license terms.

The statement is reproduced in the Debian copyright file, and it seems
valid, if it really does include PHP software as claimed by upstream.
