SCO-Caldera v IBM: Linus Torvalds Comments on SCO-Caldera's
Linux-Related Allegations
Nearly One-Half of SCO-Caldera Income from IP Licensing and
Enforcement
By Mike Angelo -- 10 March 2003 (C)
For more than a month now, SCO-Caldera has been doing some intellectual
property (IP) saber-rattling and market posturing [mozillaquest.com]
regarding its UNIX source code ownership and Linux. On 6 March 2003,
SCO-Caldera stopped its saber-rattling and pulled the sword out of its
sheath when it filed
a legal action against IBM regarding [mozillaquest.com] claims
involving the UNIX and Linux operating systems.
Of the 136-paragraph Complaint filed by Caldera Systems, Inc., d/b/a
The SCO Group, six are particularly significant regarding the Linux
kernel, and the GNU/Linux operating system, and Linux distributions.
Paragraphs 74 and 82 through 86 of SCO-Caldera's Complaint belittle and
insult Linux developers, the Linux kernel, GNU/Linux, Linux distribution
providers -- in essence the entire GNU/Linux and free software
community.
In an e-mail discussion, we asked Linus Torvalds to comment on the
Linux-related allegations SCO-Caldera makes in its Complaint against
IBM. Here is Linus Torvalds' uncensored commentary.
Linus Torvalds: Ho humm..
I'm not all that excited about commenting a lot on lawsuits, since
quite frankly I want to have as little as humanly possible to do with
such things. At the same time I obviously do find the SCO one a bit
interesting, since it's the first lawsuit ever I know of that actually
involves Linux, even if Linux itself seems pretty peripheral.
Just as well, that "peripheral" thing ;)
MozillaQuest Magazine: SCO-Caldera says in paragraph "82" that "it
would be difficult or impossible for the Linux development community to
create a grade of Linux adequate for enterprise use." (Without the aid
of the alleged actionable conduct of IBM) Is that true?
Linus Torvalds: I don't think IBM would have started using Linux if it
was true. I think IBM got serious about Linux because it noticed that it
_was_ "adequate for enterprise use" from a technical perspective, but
lacked a lot of things IBM could bring to the table (marketing, of
course, but even more than just marketing, just the presence of IBM made
Linux be taken much more seriously).
So I think IBM's involvement has been very important, but while IBM has
fine engineers, the most important part by _far_ has been the
"mindshare" part of it.
But what does "adequate for enterprise use" really mean? The marketing
and mindshare certainly _matter_ a lot for pretty much all enterprise
customers. So in _that_ sense maybe SCO is right, even though I don't
think that is really what SCO _meant_.
MozillaQuest Magazine: It sounds as though this lawsuit is not a suit
alleging copyright infringement, patent infringement, or trademark
infringement (the standard three prongs of the intellectual property
complex). Rather, it appears the Caldera v IBM action is more in the
nature of a contract or tort action.
Linus Torvalds: Yeah, I don't personally think they have any IP rights
on Linux, and I agree, it looks more like a suit over the contract
rather than over Linux itself.
I don't think they are going to win it (very very weak arguments, since
at least from a technical perspective I don't think the IBM involvement
has been that significant, and SCO was losing out _long_ before IBM
started pushing Linux). However, my personal (maybe overly cynical)
suspicion is that even _they_ don't think they'll win the suit, and it
may be nothing more than a way to force IBM back into license
discussions over UNIX itself.
So I think that 100-day license revocation thing may actually be the
most important part of the whole suit, and that the rest might be just
the excuse. If I was SCO and looking at IBM, I'd have long since noticed
that IBM has been talking about Linux taking over more and more of
their current AIX usage, to potentially eventually replace it
altogether.
So SCO sees IBM largely going away as a licensee in a few years - and
while I certainly don't have any knowledge of how much that means for
SCO, I would not be surprised if IBM licenses are quite a noticeable
part of SCOs receivables.
And what would you do? You want to get IBM back to the discussion table
over licensing _before_ IBM starts to consider the UNIX licenses for AIX
to be no longer worth it. I think IBM has announced they'll drop AIX
eventually, but I do _not_ think that IBM is willing to drop it within
three months. They tend to pride themselves on supporting their
existing customers.
MozillaQuest Magazine: What sort of impact do you believe this sort of
lawsuit filed by SCO-Caldera has on the Linux kernel, GNU/Linux, UNIX,
and the Linux and free-software communities?
Linus Torvalds: None, really. The people I work with couldn't care less.
The thrust of paragraphs 74 and 82 to 84 of SCO-Caldera's Complaint
against IBM is that without the aid of the alleged actionable conduct of
IBM, GNU/Linux would not be an enterprise/server grade operating
system. Although in paragraph 84 of its Complaint, SCO-Caldera does not
directly say it, when taken in context of the entire Complaint,
SCO-Caldera is alleging that it is the alleged actionable conduct of IBM
that provides items (1) through (5) set forth in paragraphs 84 to the
Linux kernel, GNU/Linux, and Linux distributions.
84. Prior to IBM's involvement, Linux was the software equivalent of a
bicycle. UNIX was the software equivalent of a luxury car. To make Linux
of necessary quality for use by enterprise customers, it must be
re-designed so that Linux also becomes the software equivalent of a
luxury car. This re-design is not technologically feasible or even
possible at the enterprise level without (1) a high degree of design
coordination, (2) access to expensive and sophisticated design and
testing equipment; (3) access to UNIX code, methods and concepts; (4)
UNIX architectural experience; and (5) a very significant financial
investment.
MozillaQuest Magazine: Did the Linux kernel and GNU/Linux developers
and groups lack the technological capability of producing an enterprise
level Linux without being bailed-out by IBM as SCO-Caldera claims?
Linus Torvalds: "Bailed-out by IBM"? Hardly. Oh, IBM has certainly been
very helpful, and I like the IBM engineers I work with, but Linux was
running on 16-cpu Sun sparc computers long before IBM really got into it.
In paragraph 85 of its Complaint against IBM, SCO-Caldera alleges that
the Linux kernel and GNU/Linux are limited to handling a maximum of four
CPUs.
85. For example, Linux is currently capable of coordinating the
simultaneous performance of 4 computer processors. UNIX, on the other
hand, commonly links 16 processors and can successfully link up to 32
processors for simultaneous operation. This difference in memory
management performance is very significant to enterprise customers who
need extremely high computing capabilities for complex tasks. The
ability to accomplish this task successfully has taken AT&T, Novell
and SCO at least 20 years, with access to expensive equipment for design
and testing, well-trained UNIX engineers and a wealth of experience in
UNIX methods and concepts.
MozillaQuest Magazine: Is this true? I thought the Linux kernel and
GNU/Linux can handle 32 CPUs?
Linus Torvalds: We still claim 4-8 CPU scalability. Yeah, it sure works
on bigger machines, but they are just so uncommon as to not be a big
issue yet, and most of peoples' resources are certainly spent on the
mass market (well, UP is the _real_ mass market, but most of the kernel
people tend to be fascinated by SMP issues, so we tend to target
slightly higher ;)
Normally, we end our articles with a summary and/or conclusion. We do
not do so with this article. That's because we want you to have the
benefits of Linus Torvalds' comments about the SCO-Caldera v IBM lawsuit
without any spin from us. You are getting this just the way Linus said
it and in context. Moreover, Linus Torvalds' comments are concise,
well-expressed, and to the point. The only material in this article is
Linus' comments with just enough background added by us to put the
comments in perspective and context with the allegations of
SCO-Caldera's Complaint. Thus, Linus Torvalds' comments need no
interpretation or spin from us.
