Sorry, but we should not be making any claim that _LICENSE variables are in
any way correct or exhaustive. In my opinion, they are set to the best of
our knowledge, but they are not any legal advice.
I do recognise that it should be safe to remove information from the build
files, from the docs, and the likes. It should also be safe to just list
the licenses explicitly listed in the package's own legal info (here,
the file named 'NOTICE', sometimes 'COPYING', or the likes), or in
individual source files.
People that want to make use of the output of 'legal-info' should
carefully review that information, and in case of any ambiguity, consult
with their own legal advisor.
Now, back to this libkrb5 license mess..
As a basis for this analysis (which is not legal advice), let's start
from the README file, which prominently states:
Copyright (C) 1985-2019 by the Massachusetts Institute of Technology
and its contributors. All rights reserved.
Please see the file named NOTICE for additional notices.
And thus, the NOTICE file contains a long list of various licenses. Some
are easily recognisable, other much less so.
For example, the first identified license looks like a BSD-2-Clause,
with copyright holders the Massachusetts Institute of Technology.
However, it is difficult to identify whether the following blurb is part
of the license text or not:
Downloading of this software may constitute an export of cryptographic
software from the United States of America that is subject to the
United States Export Administration Regulations (EAR), 15 CFR 730-774.
Additional laws or regulations may apply. It is the responsibility of
the person or entity contemplating export to comply with all
applicable export laws and regulations, including obtaining any
required license from the U.S. government.
The U.S. government prohibits export of encryption source code to
certain countries and individuals, including, but not limited to, the
countries of Cuba, Iran, North Korea, Sudan, Syria, and residents and
nationals of those countries.
So, if you happen to live in one of those countries, it would look like
you in fact need an additional license grant from the US government, that
the BSD-2-Clause listed above does not provide.
Now, a bit further down that file, we can see:
Portions contributed by Matt Crawford "crawdad at fnal.gov" were work
performed at Fermi National Accelerator Laboratory, which is
operated by Universities Research Association, Inc., under contract
DE-AC02-76CHO3000 with the U.S. Department of Energy.
This was part of a contract with the US government (DOE), so I suppose
that the contributions by Matt Crawford are thus in the Public Domain.
And then, what about the copyright claims for src/lib/crypto/builtin/aes,
which do not look like a license I could recognise (although it looks
like a simplified BSD-3-Clause, but I'm not so sure)?
And on and on...
So this is a typical case where the situation is hairy enough that we
should not try to interpret it, IMVHO, and let the user consult with
their legal counsel.
