      SCO: Without Fear and Without Research
      By Eben Moglen
      Monday 24 November 2003

      Theres a traditional definition of a shyster: a lawyer who, when the law is against him, pounds on the facts; when the facts are against him, pounds on the law; and when both the facts and the law are against him, pounds on the table. The SCO Groups continuing attempts to increase its market value at the expense of free software developers, distributors and users through outlandish legal theories and unsubstantiated factual claims show that the old saying hasnt lost its relevance.

      Just The Facts

      SCO continues to claim in public statements about its lawsuit against IBM that it can show infringement of its copyrights in Unix Sys V source code by the free software operating system kernel called Linux. But on the one occasion when SCO has publicly shown what it claimed were examples of code from Linux taken from Unix Sys V, its demonstration backfired, showing instead SCOs cavalier attitude toward copyright law and its even greater sloppiness at factual research.

      On August 18, 2003, SCOs CEO, Darl McBride, offered a slide presentation of supposed examples of infringing literal copying from Sys V to Linux at a public speech in Las Vegas. Within hours the free software and open source communities had analyzed SCOs supposed best evidence, and the results were not encouraging for those investors and others who hope SCO knows what it is talking about.[1]

      In Las Vegas Mr. McBride offered two examples of code from the Linux program that were supposedly copied from Sys V. The first implements the “Berkeley Packet Filter” (BPF) firewall. Indeed, the Linux kernel program contains a BPF implementation, but it is the original work of Linux developer Jay Schulist. Nor did SCO ever hold an ownership interest in the original BPF implementation, which as the very name shows was originally part of BSD Unix, and which was copied, perfectly legally, into SCOs Sys V Unix from BSD. Because the BPF implementations in Sys V and Linux have a common intellectual ancestor and perform the same function, SCOs “pattern-matching” search of the two code bases turned up an apparent example of copying. But SCO didnt do enough research to realize that the work they were claiming was infringed wasnt their own (probably because they had “carelessly” removed the original copyright notice).

      Mr. McBrides second example was only slightly less unconvincing. Mr McBride showed several dozen lines of memory allocation code from “Linux,” which was identical to code from Sys V. Once again, however, it turned out that SCO had relied on “pattern-matching” in the source code without ascertaining the actual history and copyright status of the work as to which it claimed ownership and infringement. The C code shown in the slides was first incorporated in Unix Version 3, and was written in 1973; it descends from an earlier version published by Donald Knuth in his classic The Art of Computer Programming in 1968. AT&T claimed this code, among other portions of its Unix OS, as infringed by the University of California in the BSD litigation, and was denied a preliminary injunction on the ground that it could not show a likelihood of success on its copyright claim, because it had published the code without copyright notices and therefore, under pre-1976 US copyright law, had put the code in the public domain. In 2002, SCOs predecessor Caldera released this code again under a license that permitted free copying and redistribution. Silicon Graphics, Inc. (SGI) then used the code in the variant of the Linux program for “Trillium” 64-bit architecture computers it was planning to sell but never shipped. In incorporating the code, SGI violated the terms of Calderas license by erroneously removing Calderas (incorrect) copyright notice.

      Thus SCOs second example was of supposedly impermissible copying of code that was in the public domain to begin with, and which SCO itself had released under a free software license after erroneously claiming copyright. SGI had complicated matters by improperly removing the inaccurate copyright notice. So how many PCs and Intel-architecture servers around the world contained this supposedly infringing code? Zero. No version of the Linux program for Intel architectures had ever contained it. No SGI hardware for which this code was written ever shipped. HP, which sells 64-bit Itanium servers, has removed the code from the IA-64 branch of the Linux code tree; it was technically redundant anyway. But SCOs research went no farther than discovering a supposed instance of “copying,” without asking whether SCO had any rights in what had been copied, and certainly without providing the audience to whom it was speaking any indication that the “Linux” it was talking about was a variant for rare computers from which the supposedly-offending code had already been removed.

      What the Las Vegas “examples” actually demonstrated was that SCOs factual claims were irresponsibly inflated when they werent being kept artfully “secret.” With the facts running against them even when the facts were of their own choosing, it was unsurprising that after August SCO turned to the law. But the law was not on their side either.

      Making Up the Law

      SCOs legal situation contains an inherent contradiction. SCO claims, in the letters it has sent to large corporate users of free software and in public statements demanding that that users of recent versions of the kernel take licenses, that the Linux program contains material over which SCO holds copyright. It also has brought trade secret claims against IBM, alleging that IBM contributed material covered by non-disclosure licenses or agreements to the Linux kernel. But it has distributed and continues to distribute Linux under GPL. It has therefore published its supposed trade secrets and copyrighted material, under a license that gives everyone permission to copy, modify, and redistribute. If the GPL means what it says, SCO loses its trade secret lawsuit against IBM, and cannot carry out its threats against users of the Linux kernel.

      But if the GPL is not a valid and effective copyright permission, by what right is SCO distributing the copyrighted works of Linuxs contributors, and the authors of all the other copyrighted software it currently purports to distribute under GPL? IBMs counterclaim against SCO raises that question with respect to IBMs contributions to the Linux kernel. Under GPL section 6, no redistributor of GPLd code can add any terms to the license; SCO has demanded that parties using the Linux kernel buy an additional license from it, and conform to additional terms. Under GPL section 4, anyone who violates GPL automatically loses the right to distribute the work as to which it is violating. IBM therefore rightly claims that SCO has no permission to distribute the kernel, and is infringing not only its copyrights, but those of all kernel contributors. Unless SCO can show that the GPL is a valid form of permission, and that it has never violated that permissions terms, it loses the counterclaim, and should be answerable in damages not only to IBM but to all kernel contributors.

      IBMs counterclaim painted SCO into a corner on the subject of the GPL. Not only the facts but also the law are now fundamentally against SCOs increasingly desperate position. SCO and its predecessor, Caldera, have benefited enormously from the protections of the GPL. Thanks to the GPL, SCO has been able, for example, to use the invaluable work of compiler designers and implementers around the world who have made GCC the premier cross-platform C compiler. Customer applications run on SCOs Sys V Unix because of GCC, to which SCO contributed modifications particular to its system, and for which it assigned copyright to the Free Software Foundation. Caldera and SCO could not have marketed a usable operating system product without the contributions of the free software community. SCO was happy to take the benefits, but it has unethically sought to avoid its responsibilities. The law does not permit SCO to have it both ways.

      So now it has become time for SCO and its lawyers to pound the table. SCOs response to IBMs counterclaim has been a round of absurd attacks on the GPL, its users, and its author, the Free Software Foundation. The GPL, SCOs answer to IBMs counterclaim alleges, violates not just federal statutes but also the United States Constitution. How a private copyright holder can violate the US Constitution by giving others permission to copy, modify and redistribute its work SCO does not deign to say. Legal theories arent secrets; if SCOs lawyers had anything to offer in support of this novel proposition, they would offer it. Not one case decided in the long history of US copyright affords support to this ridiculous conception of an unconstitutional copyright license. No lawyer of my reasonably broad acquaintance, no matter what his or her view of the GPL may be, takes this moonshine seriously. After failing on the facts, failing on the law, and raising no more than derisive laughter from pounding the table, even the proverbial shyster is out of luck. What will we see next from SCO, an attack on the umpire?
