You're correct. The "RSA" license in that copy of pkcs11.h  is
possibly GPL-incompatible. I'm going to remove the assertion from the
Fedora licensing list that it is compatible and leave it as unclear.
However, it looks like RSA handed pkcs11 over to OASIS in 2012, and
OASIS released new versions of those headers in 2016.
Those headers are not under the RSA license, they're under a different

That OASIS license is non-free, because it has restrictions on
modification. Which means that using these newer files is not an option.
Assuming that the pkcs11 headers (under the old RSA license) are
GPL-incompatible, due to the "advertising" clause, and that this is a
problem, the potential resolutions I can see are:
1) Since OASIS was given the copyright to the pkcs11 headers from RSA,
they could waive the "advertising" clause in the old headers, which
would make them clearly GPL-compatible.
2) OASIS could modify their IPR to make it clear that software released
by OASIS is not subject to the restrictions on modification that their
standards documents are. (My gut is that this is unlikely.)
3) The OASIS PKCS 11 Technical Committee could re-release the headers
(any version) under a known Open Source license. See:
I've CC'd Robert Relyea here, as he is listed as a chair of that
committee. Robert, if you can assist us here, it would be greatly
There is another implementation at e.g.
I don't know how clean a reimplementation that is, from the copyright
point of view. It says:
