[PATCH 0/4] Clarify License information : m4, stubdom, tools/blktap2, xen/crypto

[PATCH 0/4] Clarify License information : m4, stubdom, tools/blktap2, xen/crypto

[Lars Kurth]

This series contains some of the easier license clean-up cases, which can be fixed
by adding COPYING files or README.source files. The series specially contains:

xen/crypto and xen/include/crypto
Added a README.source file
Does not need a COPYING file: all files are imported 

m4
Updated README.source to include ax_compare_version.m4
Does not need a COPYING file: all files are GPLv2  
Exceptions are exclusively from imported files: GPLv2+ 
and Laurikari (https://enterprise.dejacode.com/license_library/Demo/laurikari/)

stubdom
Added a COPYING file as a boilerplate to explain license oddities in this directory
Added a vtpm/COPYING file which contains MIT licensed files only
Added a vtpmmgr/README.source file which contains many BSD-3-Clause files only,
that originally came from tools/vtpm_manager

tools/blktap2
Added a COPYING file 
There is some complexity here, but I believe it is not necessary to fix this at this
stage, as for some time we were discussing to remove blktap2.

It doesn't seem obvious to me during my archeology.

tools/vtpm_manager was deleted in
b918dce5bb2a665a34ff893a9df5392fb8ea429d, but it is not clear whether
your claim (the new code based off the deleted files) is true.

For one, there is no uuid.h in the deleted code -- apparently vtpm
wouldn't have to ship its own uuid library because OS has one. But then,
there is such claim in the new uuid.h, so I'm rather confused. I'm
inclined to believe that this uuid.h is either written afresh or
imported from somewhere else.

It would also be helpful if you can post your methodology for getting
the list of file so that I can check if there is something either you or
I miss.

For uuid.h, the code resembles neither Linux's nor FreeBSD's.  The
closest thing I can find is libxl_uuid.h. If that's the case, my
understanding is that he license, depending on when the code is
imported, can be either GPL or LGPL...

I merely copied the claims from the existing (c) header files in the
files below, which all say

  5 * based off of the original tools/vtpm_manager code base which is:
  6 * Copyright (c) 2005, Intel Corp.
  7 * All rights reserved.


So I was merely restating the information, which was already present,
assuming that it is in fact correct. Uuid.h seems to have been introduced
in the same commit as all the files below.

Will fix the newline and other issues.

[PATCH 4/4] blktap2: Added COPYING file

[Lars Kurth]

Blktap2 has some complexity, as some files do not have (c) headers
and the directory did not have a COPYING file. At this stage, we
have not verified the intention of (c) holders. We may do this in
future, if the need arises.
