"Stolen" SCO Linux Code Snippets Leaked
stere0 writes "An article (in German) published on the German IT news site Heise includes two pictures (1, 2) of the "stolen" source code SCO claims to be theirs. Part of the first screenshot has been scrambled, the font has probably just been changed to Symbol; can anybody decipher it? I searched for the code snippets on Google. The code does indeed come from the kernel; the photographs show what seems to be lines 88-102 and 109-123 of /arch/ia64/sn/io/ate_utils.c from the 2.4 kernel tree. " Update: 08/19 16:39 GMT by M : LWN has a nice piece tracing the origins of the disputed code, and showing that SCO is simply lying.

The Gentoo People and an AC the previous SCO thread beat me to it. There's a very interesting discussion over at LWN, in which Bruce Perens points out that Caldera has put that code under a free licence.

Here's a semi-readable, slightly-cleaned babelfish translation... it'd be great if somebody who can actually speak German could post a better one...
The fight for the legal standard of Linux develops more and more to the show piece: Still two weeks ago ago on the Linuxworld had itself boss Mathew Szulik as the rescuer of the free world explained and all Linux trailers to the fight against the chains of the commercial software industry called. Now geriert itself its opponent Darl McBride of SCO still more martialischer: a James bond in the struggle with dark power -- the open SOURCE movement.
SCO executive committee Darl McBride used two full hours for the prelude of the SCO forum, in order to represent the legal position of its company. With pictures and title music from James bond films the manager sought itself to join in the faithful ones of the former cult company from Santa Cruz for fight for property. The SCO Group leads a law case with IBM because of alleged copyright infringements and abuse of SCOs protected Unix program code in Linux. Star lawyer David Boies, which attained celebrity as a complaint representative of the US government against Microsoft, represents SCO IBM over 1500 Linux Grossanwender printing reminder approximately from SCO kept and was requested to pay royalties.
Supported of its vice-president Chris Sontag showed McBride of examples from the code of the Linux Kernelversionen 2,5 and 2,6, which are to prove that program sections were transferred invariably from Unix -- an example shown by SCO to code comments in the picture left ( version increased ). Identical typing errors in the comments as well as unusual ways of writing would have left traitorous traces, to stated Sontag. Around this to prove McBride a team for pattern recognition had angeheuert, around ten thousands from program lines to through forests. The few code sequences shown apart from the comments were made to a large extent illegible, alleged, in order to protect SCOs author-genuine. They would stand however representing for thousands of program lines, for stressed Sontag. From several persons or groups at different times parts were transferred illegaly to Linux and distributed sourceopen at users and developers. At the contentious software it goes besides not around simple or trivial functions, but important operating system characteristics for the fitness with fastidious tasks and in extremely safe operating conditions into enterprises. In addition belong the multi-processor mechanisms NUMA and SMP, which were to be had under Unix Lizenzbedingungen only with expensive hardware in the value of ten thousands from US dollar to.
Approximately 700 crucial code lines of the SMP technology are to have moved from Unix into the Linux releases 2,4 and 2,5. Altogether SCOs testers over 800.000 lines would have found duplicated program text -- an example of SCO shows the picture right ( version increased ). Attorney Mark Heise from the Boies boies-Kanzlei came along for the support of the SCO managers on the podium in read Vegas. It made clear that a GPL license did not protect against the requirement for authority of SCO. The Unix license, which bought SCO 1994 of the original Unix inventor RK & T, guarantees SCO property at Unix system v copyrights and all RKS & t-software and Sublizenzrechten. Originally the license agreement defined by RK & t-lawyers, which changed over by purchase to SCO, is clear in addition regarding the range and consequence of the license, stressed the lawyer. Afterwards the license grants the "right the software products to the licensee (for example IBM) to own business purposes to use internally", quoted Marks of Heise from the contract text. "modifications and derivatives of results are to be treated like the original software products", continue to be called it there. And they "cannot become used for others or by others".

The System V comments have been stolen!!!
Obviously no actual code has been used. But the comments, the key component of the intellectual property that makes up SCO, has been lifted near verbatim and ruthlessly incorporated into Linux. Oh, the injustice.
When will it end?!?
To sum up, this code is in 2.4.x but not 2.5.x, was also present in BSD which means its open source based on the case the BSD creators went through in the early 1990s. Have SCO really so poorly researched these examples that this is the best they can show us?
The thing is that it actually is the Windows Symbol font. I can read Greek (Ancient Greek at least) and while the alphabet used is the Greek one all that somebody did was highlight the text in question and change the font to Symbol, which is what Windows calls its Greek font.
In other words it's English written using the Greek alphabet. Why somebody would do something so silly puzzles me, however.
Here's the earliest implementation people have found so far, from 1979 (before SCO was "born"):
l loc.c.html
1 BSD/sys/sys/subr_rmap.c
http://minnie.tuhs.org/UnixTree/V7/usr/sys/sys/ma
And here's where it was part of BSD 2.11 circa 1992:
http://unix-archive.pdp11.org.ru/PDP-11/Trees/2.1
Oh, how I hope the mainstream tech press "gets" this.
I think that it looks like SCO's snippet, doesn't even belong to them, compare following which is: Copyright 1986 Regents of the University of California
That's BSD
Both snippets relate to the first function in that file - malloc(). It's a simple malloc implementation.
The second Heise picture is the body of the function, pretty much. There is now an SMP spinlock in there, and what appears to be some assertion on the size of the memory area (some kind of bigmem check?). Also, the for loop is initialised with a function, which is probably also something memory related, again possibly bigmem related.
So, it relates to the areas SCO said it did. I doubt very much they can claim the code was copied from SysV wholesale. I would be surprised they could even claim that the three changed lines from the ancient Unix are not obvious - e.g., for it to work in SMP you basically need a lock. Although, it would be surprising for the locking mechanism to be identical - so they perhaps have some point here. But, the majority of the function cannot be claimed as copied, surely....
"Elmo knows where you live!" - The Simpsons
Here or Here
My reaction is "so what." I wouldn't be surprised if you saw those same lines in NT. They probably originated in BSD as so many others have stated and will continue to state. If it is true Caldera sent an employee or two to IBM to help *beef up* Linux, then that would be a valid explanation as to why the code is the same. SCO is Caldera and they cannot deny that no matter how many times they change their corporate name. They put the lines in there and they distributed the offending versions of Linux under the GPL. Just because they are no where as successful as RedHat or SuSE gives them no rights to try to weasel out of it now... When will SuSE, Xandros, and Lindows join the RedHat lawsuit against *Caldera*???

How could the IBM engineers miss it.
With pictures and title music from James bond films the manager sought itself to join in the faithful ones of the former cult company from Santa Cruz for fight for property.
Sorry, but Darl is no 007. If I had to cast him in a James Bond movie he would be something like "henchman #7 who gets shot by his own soldiers and falls off a banister to hang by his neck in front of James Bond." If he were even able to be given a name such as "Odd Job" or "Goldfinger", Darl's name would be "Ass Hat" or something like that.

Obviously they were silly enough to believe that since they had every legal right to copy it, they didn't need to hide the copying.

IT DOES NOT MAKE SENSE!
The actual source code in question isn't of primary importance at this point since the main SCO complaint is against IBM, and IBM's source code is in the Linux source tree because they donated it. Its public knowledge that IBM donated code to Linux, and SCO is just showing the code to selected neophytes for shock value. "SCO showed me source code from Linux and System V, and THEY WERE THE SAME! I'm shocked! IBM must be guilty".
SCO may eventually make other claims that all of Linux is their stolen property, but for the time being the focus should be on IBM, and in that case looking at the code does nothing but provide FUD fodder for clueless news outlets. The headlines will read "Industry analyst says lines of code are the same, SCO up 3 points".
The real issue here is this is a licensing dispute between two software companies, and it says nothing of value about the open source development process or Linux. Its in SCO's interest to bring these broader issues into the picture in order to put pressure on IBM to settle, but DON'T TAKE THE BAIT!
It is so great that everyone here in the /. community is so on top of this. It's great that so many of you know where to look to find the true origins of the "stolen" code, that by today's evidence, is obviously not stolen.
However, this is not yet the time to celebrate. SCO is claiming 829,000 lines of code was "stolen" from SMP code alone. Of course this is probably ridiculous, but a screen shot of some comments from the late 70's only shows that those particular comments were not stolen.
There is still a lot of work to do. Mr. McBride is creating so much work because for each claim of copyright, the onus is going to be on the linux community to find the origins and prove the allegations wrong. SCO is only going to present SCO code that was supposedly 'written' before the linux code. Their entire offense is going to rest solely upon the fact that they have a plaintext file with an earlier date than the linux kernel's corresponding code file.
The work is going to be on our backs to locate even older code that SCO's predecessors used to write SYS V. I would raise the bar as well and go so far as to attempt to show that SCO's code was itself misappropriated.
We are just now starting to see how much work we have in front of us, and believe me, that mountain of work is only going to get larger. But, as with the development of linux itself, there are millions of developers across the globe that will be able to find evidence to refute each and every one of their fraudulent and baseless claims.

Which means that SCO is using BSD/PDP11 code. This is also part of the code they called "Ancient Unix", because it was old and obsolete, and posted it on the web. Initially they wanted a $100 "license" fee to download the code, but the number of takers were so few that SCO opened it up to free access. We're they hoping someone might copy some of the code into the Linux kernel? Some might suggest that this was their plan all along, but a lot of the Sys V code would require a "glue", as former SCO employee Christoph Hellwig put it, in order for the SCO code to work in Linux. That kludge would not pass lkrnl checking.

Call me paranoid....but this might be a trick by SCO to probe the defences of the Open Source community, by having us do their historical code research for them, gratis.
What do I mean? An example.

I know this sounds paranoid, and you might think ol' Darl is no magician, but he has conjured ~ 20X increase in SCO "worth", from an essentially worthless company.

The SCO Group, Inc. (Nasdaq: SCOX - News), the owner of the UNIX(R) operating system, today announced the appointment of Gregory Blepp as vice president of SCOsource. Blepp will report to Chris Sontag, the senior vice president and general manager of SCOsource, the division of SCO tasked with protecting and licensing the company's UNIX intellectual property.
Blepp, a former VP of International Business at SuSE, brings to SCO a wealth of experience in marketing and business management from time at Network Associates and Computer Associates. Blepp's appointment is taking place at SCOForum in Las Vegas this week where he is being introduced to SCO partners and resellers.
"We're pleased to have Gregory Blepp join SCO to assist in our efforts around SCOsource in Europe," said Chris Sontag, senior vice president and GM, SCOsource. "We look forward to using Blepp's talents and expertise in assisting the company to properly license SCO's valuable UNIX intellectual property."
Is this world full of insane people ?
Dennis Ritchie has written So far as I can determine, this is the earliest version of Unix that currently exists in machine-readable form. ... The dates on the transcription are hard to interpret correctly; if my program that interprets the image are correct, the files were last touched on 22 Jan, 1973. ...
That may be the case in many of their claimed 'infringing lines' but not in these two.
The first one shows comments (not code) which match. They're also straightforward descriptions of functionality, date back at least to 1979, and occur in a number of old unix versions which have been commonly read and used for teaching purposes for years, as well as the Lions book.
In this case the comment definately predates Linux so couldn't have been copied from Linux, but the fact it occurs in Linux code is not strong evidence of copyright infringement.

The second section of code is copyright of and contributed by SGI, and concerns functionality that SysV doesn't have. It's only relevant on the assumption that SCOs theory that it owns every technology any Unix licensee ever added to their own version of Unix holds water, which means only if the court winds up throwing the entirety of copyright law and precedent out the window and writing new law just for SCOs benefit.

Throw some challenges to the free software community at slashdot and watch thousands of brilliant minds load-balanced working like a huge beowulf processing information online (a bit like SETI) to achieve the commonly understood goal; in this case to defend Linux.
If you want millions of man-hours with full motivation and some of the best skill to work for you for free, go to slashdot provided the task is enormously beneficial to the free software community. No corporation can spend any amount of capital or hire any number of people to match the productivity of geeks running on fuel that is pizza and beer to change the world.

The problem is IBM only hires the top 5% of any given graduating class. Basically if you don't have a 3.75+ GPA, forget about it. Therefore they hire all the geeks who never considered cheating and don't know how to get by in the real world. If they just hired a real person as a "conformance officer" occasionally, such trivial mistakes wouldn't slip by.
They who would give up an essential liberty for temporary security, deserve neither liberty nor security
If these functions were implemented in Perl, they would be guaranteed to look different than the System V!
So let me get this straight.
A patch was submitted by someone from HP, containing a Silicon Graphics, Inc. copyright line, along with at least one chunk of code that is nearly identical to several early BSDs, as part of an SMP implementation, that SCO is claiming IBM donated to the Linux kernel in violation of a contract?
What. The. Fuck. I don't even want to try and figure out the web of licences, contracts, and original sources for this code. Based on other comments, it looks like a basic (crappy) implementation of memory allocation. On top of it all, whoever at SCO prepared the PowerPoint presentation managed to mistype the supposed SysV code.
Several scattered thoughts come to mind, among them "chutzpah", "pump and dump", and "someone's going to jail when this is all over."
Someday, you're going to die. Get over it.
You see! This is why they didn't show their evidence! You all have gone and poked holes in it. Shame on you, you're going to be responsible for the death of a corporation!

The battle for the legality of Linux is becoming increasingly melodramatic: Two weeks ago, RedHat CEO Mathew Szulik declared himself Saviour of the Free World, and called for all Linux-Supporters to join the battle for freedom from the software industry. His opponent darl McBride from SCO strikes an even more martialic pose: a James Bond fighting against the forces of Darkness -- incarnated in the Open Source Movement.
McBride spent no less than two hours at the beginnign of the SCO symposium to clarify his company's legal position. Backed by pictures and music from various Bond flicks, he attempted to rally the supporters of the formerly cult company from Santa Cruz to his fight for the Good Cause. The SCO Group has started a legal battle against IBM for alleged copyright violations and misuse of SCO-owned UNIX code in Linux. Star attorney David Boies, famous for fielding the US anti-trust effort against Microsoft, represents SCO against IBM. More than 1500 major Linux-using companies have received admonitions to pay licensing fees from SCO.
With Vice CEO Chris Sontag as sidekick, McBride offered several examples from Kernel 2.5 and 2.6 that are meant to prove that several program parts were transplanted unmodified from UNIX -- such an example is here. Duplicated typos in the commentary as well as unusual coding style have left traces, says Sontag. To porve this, McBride employed teams for pattern recognition to parse tens of thousands of lines of code. The few sequences of actual code shown besides the commentaries were largely scrambled, supposedly to protect SCO copyright. They were, however, representative for a thousand other just like them, emphasizes Sontag. Multiple developers had illegally transplanted code into Linux and then distributed the source to users and developers. The software in question is nothing trivial, but contains integral operating system functions used for demanding applications and extremely secure environments in companies. Among them are the multiprocessor technologies NUMA and SMP, which under UNIX licensing cost 10,000$ or more.
Rouhgly 700 lines of code for the SMP technology are supposed to have gone into Kernel versions 2.4 and 2.5. All in all, SCO claims to have found no less than 800.000 lines of duplicated code -- one example is shown here. Attorney Mark Heise from Boies' law firm joined the SCO chiefs on the podium in Las Vegas. He emphasized that the GPL did not offer protection against copyright claims from SCO. The Unix license that SCO bought from AT&T in 1994 guarantees SCO ownership of System V copyright and all AT&T software and sublicense rights. The license agreement, originally drawn up by AT&T lawyers, which has since gone over to SCO, is unequivocal concerning scope, Heise affirmed. Accordingly, the license gives the licensee (e.g. IBM) the right to use the software internally for commercial purposes. Modifications and derivatives are subject to the license just like the original. They cannot be used for or by third parties.
"Now we finally know how Linux has matured from hobby OS to IT-company platform," Sontag jibes. "If something sounds too good to be true, it usually isn't," topped McBride. Evolved technology simply cannot be had for free. "Free Software -- not our thing." UNXIX comprises 20 years of development work: Based on it, SCO wants to make money for another 20 years. McBride appealed for support from partners and developers from the UNIX community, otherwise, "the times for good business might soon be over." GPL and Open Source destroy legal business models -- compensations and a legal business model for the future are therefore necessary. Heise seconded: That SCO once distributed its code as Linux distributor, did not mean that Linux users where protected from all demands because of the GPL. Copyright for code can only be obtained by a written contract wit

I guess I shouldn't be surprised that there exists a "dung cheese" in German cuisine, but I am repulsed.
Thanks for sharing. : )
Why yes, I AM a rocket scientist!
The last link shows the code apparently came from SGI. Isn't SCO claiming that IBM contributed the so-called infringing code?
No.
The accusations made by SCO have been very unclear. The IBM case is about acts by IBM which SCO claims breaches the IBM/AT&T contract. It involves contributing code IBM got by buying Sequent and by participating in Project Monterey. This technology includes RCU, NUMA, SMP and scalability.
Independantly, SCO claims that there are many lines of code copied from Sys V into Linux. They have not yet filed any copyright suit against anyone since they only just got the copyright registrations issued.
Don't confuse the two very different legal issues.

Bruce Perens has written an analysis of the code that SCO claims was wrongfully copied into Linux: http://perens.com/Articles/SCOCopiedCode.html
I find it sad to see how many here call sharing code for stealing. Without sharing code, there can be no further progress on computer science. Instead of having ad-hoc solutions, it can evolve into a fully fledged engineering science. But only if people can collaborate on standards and further its progress instead of being busy putting up tool-booths for inventing the inevitable.
You never drive over a bridge proprietary to BigCorporation(R)(TM)(C). You drive over an assembled construction errected by standardized plans, tools and mass. Instead, we have a mad goldrush that sinks the economy through the floor.

In my school, the people in CS who got the 3.75+ GPAs were the professional students, who were only willing to learn what would help them on the exams, but not anything useful. If it wasn't going to help them on their exam, or help them complete projects. they simply didn't want to know about it.
The "real" geeks who really cared about CS, didn't always score quite so high, but they had a passion for computers, and therefore learned things outside the curriculum and picked up more useful skills, tended to spend their free time "tinkering", and therefore their grades in other requisite Liberal Arts courses may have suffered a bit.
At one point, we had a professor for an "Operating Systems" course, who had lots of real world experience, and his teaching style was less academic and more focused more the real-world. This drove the "3.75+ professional students" crazy. They didn't know how to study for his course, because they actually had to think in ways they weren't used to. His course threatened their GPAs, so they protested. The "geeks" loved his course and got straight A's in it. Too bad the instructor was a bit of a push-over on grading, and ended up bending to the other students' demands, and ended pushing up their grades more than they deserved.
I'm not saying that everyone who has a high GPA is this kind of student. I'm just saying I wouldn't decide who to hire based on GPA alone, from on my personal experience.
By reading this sig, you agree to the terms of my sig license.
Copyright infringement is NOT part of their suit against IBM. The only place where SCO has alledged this, is in their statements to the press, in the form of "IP", etc. To the best of my knowledge, they have not filed a copyright infringement case against ANYONE. I have read SCO's original and amended suits against IBM, it is simply a contractual suit, generally breach of contract, and disclosing "trade secrets". Which is really funny, because they specifically name NUMA, JFS and SMP in their lawsuit, refering to what IBM contributed to Linux. And that is funny, because SCO does not own or "control" that software at all. Most if it is copyrighted by IBM or by company that IBM bought (Sequent) or others, but NOT SCO. SCO's entire case, based on their filed amended complaint, hinges on the court ruling that NUMA, JFS and SMP are "derivative workds" of Unix System V. But that is very highly unlikely, in my opinion.
