I'd guess there would be a bouncing of dates between the first Linux
entry and the first Unix entry, ie. cross-pollination, not
uni-directional pollination. (And I'd guess that there is sufficient
GPL'd code in UNIX that UNIX itself is in violation of GPL.)
I wouldn't be surprised if that is one reason why Caldera is keeping secret
exactly what they are basing the claim. I doubt that the IBM lawyers are so
stupid as not to evaluate the timeline as to when the code got where.
However, the so-called "analyst" that looked at the code was probably not
looking at any time line but "Oh, the code is the same. Since the UNIX
source is priopriatary, the Linux *must* have taken it from there". (Or
some other such nonsense).
Personally, I think that IBM might still have a fight ahead, since it may
need to prove in court that they were not the source. However, finding all
of the SCO and Caldera references made me feel a lot better. First, a
(possible) source of "contamination" is pretty clear and pretty obviously
this person knew the insides of the UNIX code. Second, since it is "the cat
is out of the bad" issue for Linux in general, I don't see how Caldera
could get away with anything involving end users.

Please excuse the lenght of this post. However, a google search for
"SCO Hellwig Caldera Linux " produces 194 results. As you read down the list
one can confirm the existing relationship with SCO developers and Linux
developers. Also, near the end of this post the is reference to IA-64
development. To the point, there is questions about code and api's that are
available that are directly evident of developer access to said code and
api's revolving around the Unix and ia-64 question. It is also evident that
most, and apperently a significant amount of this was readliy available and
that SCO was playing both sides of the fence - developing for both Unix and
Linux code bases.

The support code hass been in the SuSE^H^H^H^HUL for quite a while now,
so this isn't exactly an surprise (except that they actually chose
SCO as their UL brand instead of SuSE).
Well gee.. Glad you clarified that for all of us...

Torvalds cited a linux-kernel mailing list (lkml) posting from Christoph
Hellwig, a former employee at SCO, then called Caldera. Hellwig points out
the impracticality of actually getting copied code from UnixWare accepted by
the tough critics on the mailing list. "The kernel internals are so different
that you'd need a big glue layer to actually make it work and you can guess
how that would be ripped apart in a usual lkml review", Hellwig wrote.

David:
The materials you are looking for are currently available at the link
Christoph has noted below. They will be changing soon however. When
they do I will make sure the link to this and other ones from SCO are
updated on the LSB specification references page so they can be
followed/found.
In the future bookmark "http://www.linuxbase.org/spec/" to start
drilling down to find the references.

System V Application Binary Interface - DRAFT - 24 April 2001
The Linux abi is a patch to the linux kernel that allows a linux system to run
foreign binaries.
This was developed and written by Christoph Hellwig and Joerg Ahrens as a
follow on to the iBCS/iBCS2 project written for the older 2.2.x kernel by
Mike Jagdis.

I garner that further searches and refinements on this and similar subjects
will produce further evidence of on-going access to SCO unix knowledge base,
code, api's and the ongoing help/contribs by various SCO personal to both
ia32 and ia64 developments. It appears, at least on a cursory level that up
until lately SCO was actively involved in both the 32 and 64 bit development.
I further submit that perhaps once SCO found that other systems were
preferred for implimentation over SCO's products that they decided to pull
this stunt.
Cheers, Curtis.
