Red Hat Developer Demands Competitor's Source Code

sfcrazy writes "A very serious argument erupted on the Linux kernel mailing list when Andy Grover, a Red Hat SCSI target engineer, requested that Nicholas A. Bellinger, the Linux SCSI target maintainer, provide proof of non-infringement of the GPL. Nick is developer at Rising Tide Systems, a Red Hat competitor, and a maker of advanced SCSI storage systems. Nick's company recently produced a groundbreaking technology involving advanced SCSI commands which will give Rising Tide Systems a lead in producing SCSI storage systems. Now, RTS is blocking Red Hat from getting access to that code as it's proprietary. What's uncertain is whether RTS' code is covered by GPL or not — if it is then Red Hat has all the rights to get access to it and it's a serious GPL violation."

      This is a no lose political play by RedHat; they never expected there was a real licensing violation. Consider the two outcomes here:

      -Rising Tide Systems says that it developed their EXTENDED_COPY and COMPARE_AND_WRITE commands under a different license, walled off from the main code they contributed to the kernel under the GPL. (That's what they've done now). Then RedHat's sales position is that people who buy Rising Tide's Linux are getting a licensed closed-source product. It is guaranteed not to integrate smoothly with the *real* Linux kernel because of the architecture needed to keep it licensed differently, it's not getting community review for features and security issues, and if Rising Tide goes out of business their customers are screwed--good old fashioned vendor lock-in.

      -Rising Tide rolls over and releases their code into the mainline kernel. Now RedHat benefits from it being available too.

      RedHat makes much of its money from companies that are moving to open-source because they are sick of the downsides of commercial software, which go from quality issues to vendor lock-in. They're compelling Rising Tide to either give away somethings they're trying to keep closed, or to shame themselves by admitting they're not really an open-source team player. RedHat can launch that sort of acusation safely because they are operating very transparently. We know that companies are not locked in to RedHat from how many clones of it exist. When CentOS and Scientific Linux work, clearly RedHat is sharing all the important parts. And if you've made that part of your competing position, preaching down to people who are not sharing as being sellers of inferior products is very easy to do.

Vladislav Bolkhovitin has a nice, solid option in SCST (http://scst.sourceforge.net/index.html) that was skipped over in the upstream kernel in favor of the LIO stuff from Rising Tide Systems. We moved away from SCST to LIO at work even though we didn't think it was quite as good simply because being embraced by the community usually means that you win long term. Andy basically makes this point:

      "But let's forget licenses and talk community. Looking back, can anyone say that your push to get LIO accepted into mainline as the kernel target was in good faith? Back before LIO was merged, James chose LIO over SCST saying to the SCST devs:

      'Look, let me try to make it simple: It's not about the community you bring to the table, it's about the community you have to join when you
      become part of the linux kernel.'

      RTS behaved long enough to get LIO merged, and then forget community. James is right, community is more important than code, and licenses enforce community expectations. RTS has appeared just community-focused enough to prevent someone else's code from being adopted, so it can extract the benefits and still maintain its proprietary advantage."

    Hi Alan and others,

    I've been advising Rising Tide Systems (RTS) in this matter. Please let me reassure you that RTS is acting on advice of counsel.

    RTS (and specifically Nicholas Bellinger) wrote the scsi target code and owns its copyright. We registered that copyright at the Library of Congress. RTS contributed a version of the scsi target to Linux for distribution under the GPL. On behalf of Marc Fleischmann, CEO of RTS, I can reassure you that RTS remains committed to the Linux project and will continue to contribute to it. We are pleased that RTS software is a part of the Linux distribution under the GPL.

    RTS also has a commercial software business. It distributes versions of its scsi target code that support features and functions not officially in Linux (or at least, not yet). That commercial RTS business includes the licensing of those derivative works of its own code to its own customers. Nothing whatsoever in the GPL or in the policies of the Linux Foundation prohibits that.

    I would also like to address some comments made on these lists by Andy Grover and Bradley Kuhn.

    First, I hope that we can tone down the arguments about whether the use of Linux APIs and headers automatically turns a program into a derivative work
    of Linux. I think that argument has been largely debunked in the U.S. in the recent decision in Oracle v. Google, and in Europe in SAS v. World
    Programming. Does anyone here question whether the original work that RTS contributed to Linux (and that *is* under the GPL) is an original work of
    authorship of RTS despite the fact that it links to other GPL code using headers and APIs?

    Second, we are grateful for the efforts that Bradley Kuhn and others put in to enforce the GPL. As I said above, RTS owns and has registered the
    copyright on its scsi target and will enforce it if necessary. So Brad, we may solicit your assistance if we find any third party who is distributing
    an unauthorized non-GPL derivative work of the scsi target now in Linux. RTS, of course, retains the exclusive right to do so, but no third party can
    do so without a license from RTS.

      Actually, the Oracle case is pretty relevant. Oracle's argument was that the API itself of java - the structure, sequence and organization of it - was copyrightable, not just the code that implemented the API. Google clean room re-implemented the code that made up the API, but kept much of the structure of the API itself. The court decided that the API wasn't copyrightable, a good decision. Ergo, anything that merely USES an API cannot be a derivative work of the code that implements the API, as the API itself isn't copyrightable - if that wasn't the case, that would open up a really huge can of worms. In effect, the API becomes a firewall between two differently licenced bits of code. Which is of course what nvidia use for their binary blobs, for example.

      Anyway, even if we assume the scsi target code in question static links to code beyond the API and does thus become a derivative work, then the upshot would be the code in the kernel... would have to be under the GPL v2. Which it already is. So it's rather a moot point.

      As long as the code in RTS' private repository has no back-ported GPL code from the kernel, i.e. they haven't imported 3rd party written GPL covered patches into
      their own private code, then they can dual licence their private version however they like. Putting a version of their scsi target software into the kernel under the GPL makes no impact whatsoever on their copyright of said code, even if it is subsequently modified in the GPL kernel version by others. They can't of course fork the GPL version with others contributions and take it private without every contributors permission; but that's not what they're doing by the sounds of it.

      As long as the code-flow was one-way - i.e. private to GPL, not two-way including GPL into private, they can write performance improvements to their commercially licenced one all day long and not port them to the GPL version in the kernel as much as they like.

      And so what, anyway? Linux gets a decent SCSI target (I've used it a few times in production; it does what it says on the tin) it wouldn't otherwise have; and RTS have a commercial product for those wanting a higher performance product for high-end usage, thus allowing them to actually stay in business. Most code in the kernel, and the gnu/linux platform comes from individuals working for or sponsored by companies; those companies make money by various means, and that's what pays for the coders. Hobbyist coders do produce quite a bit of course, but linux wouldn't be where it is without commercial support.

      And I've just realised why the API argument is important. If using the API makes code a derivative work, then the commercial version of the SCSI target module using the GPL kernel APIs would also have be GPL licenced. But given the Oracle-google case, that seems a hell of a reach, and certainly APIs were not considered to create derivative works before anyway - that's rather the point of an API, to allow two pieces of code to communicate without getting up in each other's business...

    Besides, its only the back-flow of contributed changes that would make the GPL apply to their original code, and perhaps not even that
    would be sufficient. Does a contributed two line patch drag the entire original proprietary source into the GPL?

    Not quite - if the proprietary module links into the Linux subsystems, as seems extremely likely, then the whole module likely becomes a derivative work, the exact details become very important in that case. The nVidia drivers walk this line, which is why you don't see them integrated into with any Linux distro - doing so would tilt the balance towards the derivative work interpretation and is likely to elicit a cease-and-desist letter.

    Emphasis mine. It doesn't say just customers. It doesn't say just people who have the binaries. It says "any third party". That means any third party, no further restrictions or conditions.

    I think your interpretation is wrong. If company A makes a special binary for company B along with an offer for source code, then random company C can't come and demand the source code for company B's version. The FSF FAQ says:

    (...) When users non-commercially redistribute the binaries they received from you, they must pass along a copy of this written offer. (...) The reason we require the offer to be valid for any third party is so that people who receive the binaries indirectly in that way can order the source code from you.

    That is to say, if you have an offer they must honor it no matter who you are. If you don't have an offer, you get nothing. It's like a cashier's check, whoever holds it can cash it. But no check, no money.

    UNIX preemptively multitasked in 1969. Kinda predates Amiga.

    The earliest example of a protected memory model using separated memory paging I can think of is OS/2 (1987).

    If by "separated memory paging" you mean "paging in separate per-process address spaces", the earliest example I can think of is the Berkeley Timesharing System on the SDS 940 (1966 or so), followed by Multics (1969), TSS/360 (1967 or so), and TENEX (1968-1970 or so).

    (Given that you mention UNIX in 1969, you're not restricting this to OSes running on IBM-compatible PCs.)

    I think you got the who needs evidence switched. They didn't release any evidence it wasn't because they never accused anyone or anything. It's the onus on the accuser to prove the cause.

    It's not guilt until proven innocent.

  34. Re:Yes, it WAS about GPL, in a roundabout way. by shutdown+-p+now · · Score: 3, Informative

    From LKML thread in question. Some choice quotes:

    "You ship Linux as part of RTS OS. Even if you had not asked for LIO to be included in mainline, this would still be true and would require you to publish your changes under the GPLv2."
    (http://marc.info/?l=linux-kernel&m=135240979330272&w=2)

    "Is your code an independent and separate work from the Linux kernel? Some tests might be: can it be used without the Linux kernel? Can it be used with alternative kernels? Even if the answer to these questions is YES (which it isn't) then that second quoted sentence would still put your code under the terms of the GPL, since RTS OS distributes its changes along with the Linux kernel."
    (http://marc.info/?l=linux-kernel&m=135250402701805&w=2)

    "RTS OS is based on a stock Linux enterprise kernel. This Linux kernel has naturally the ability to load either one of our standalone self-contained target module versions without any modifications."
    (http://marc.info/?l=linux-kernel&m=135242690804322&w=2)

    "To be clear, we wrote that code entirely ourselves, so we have the right to use it as we please. The version we use in RTS OS is a different, proprietary version, which we also wrote ourselves. "
    (http://marc.info/?l=linux-kernel&m=135240512628253&w=2)

    So, to sum it up: it looks like they distribute the Linux kernel, bundled with a bunch of dynamically loadable proprietary modules of their own authorship. They claim that said bundling does not produce a derived work, because the modules are not physically part of the kernel, and they can load into any Linux kernel, not just this particular one (i.e. they're written against an interface). This is exactly equivalent to claiming that it's okay to use a GPL'd library so long as you dynamically link to it, something that FSF has long claimed is a no-no. Similarly, kernel developers have also claimed that making a module dynamic rather than compiling it directly into the kernel does not change its status as a derived work. It is this claim which is being disputed here, and if it is successfully defended, then it makes GPL effectively identical to LGPL in practice.

    Red Hat contributes heavily to Linux, but they use tons of code which have been written by people who haven't been paid by them & they make money off it. But they don't want Oracle to make money off code Red Hat wrote. So they make it difficult for Oracle. What if the millions of people who wrote free Linux code had made it difficult for Red Hat in the first place.
