Linus Puts Kibosh On Banning Binary Kernel Modules 494

Posted by kdawson from the distribution-vs.-use dept.
microbee writes "On LKML's periodic GPL vs. binary kernel module discussion, Andrew Morton hinted that he favors refusing to load binary modules in 12 months. Greg Kroah-Hartman then posted a patch to do exactly that. Surprisingly Linus chimed in and called it 'stupid' and a 'political agenda,' and even compared it with the RIAA's tactics. Later in the same thread Greg withdrew his patch and apologized for not having thought it through."

      Actually, (And in contrast to the majority of LKML spats that get posted here), Linus' post is actually rather accurate, and I agree with his reasoning. I don't want the RIAA being able to prevent all fair use just because some people make 'un-fair use'. I don't want to prevent other people from doing the same things with my works or I am being hypocritical. (Just to use one example, I realize kernel binary modules have nothing to do with fair use, and everything to do with derived works.)

    Seriously, there should be no "bans" of any code from Linux. That defeats the entire point. Banning people from loading their own kernal modules because YOU think there may be some weird legal issue is exactly the same as making your media player play only DRM files.

    This should be a short topic, Linus' reply (which if you haven't read you should) should finish the entire conversation right here, it's a stupid and petty toys out of the pram act and I'm glad he shot it down.

    Hopefully if it somehow does make it into the trunk, there will be very quickly versions with it removed releases as we go forward too because I don't think the wider community will have any truck with this at all.

        Certainly you're not one of the brave hackers that didn't stop developing linux in the early days despite of the severe lack of drivers.

        These days you can boot linux anywhere. But you know, there was a time (not that far ago) when Linux (and BSDs) didn't support almost anything. Those people really believed in open source, and they didn't mind spending many hours of their life reverse-engineering obscure hardware. They also didn't mind selling their incompatible hardware and buying linux-compatible hardware in order to run their wonderful open source OS.

        And you plan to to switch windows if the linux developers plan to ban propietary modules. You aren't switching your graphics card and buying a linux-compatible one (something you can fix with money). You just plan to switch windows.

        We're lucky that the early open source hackers weren't like you - if they had switched to windows every time they found a barrier we wouldn't have open source operative systems today. Linux has got big without the help of propietary drivers and despite of the ridiculous hardware support and the one way of getting even bigger is following the same path. We don't need propietary drivers, fuck them.

      The point is the message that this brings across. At the moment people are pretty lax about binary dirvers. A ban on them in the vanilla kernel will go a long way in telling the driver vendors to make their specs free or get out of Linux land. Free drivers would be awesome, but I don't know if Linux is strong enough to actually influence the vendors at this point so we might end up with nothing. Plus, implementing this at the code level seems like the wrong place to be doing it. As Linus said, the license ought to control the distribution not the usage.

    But the fact is that there is a large number of copyright holders for the Linux kernel, not just Linus himself. Not all of these copyright holders accept binary kernel modules, and thus they should be considered illegal to distribute with the kernel.

    However, refusing users to shimmy in a binary module themselves is wrong. The GPL clearly states that it only covers distribution, not usage, so users are perfectly entitled to do whatever they want to the kernel as long as they do not distribute it. Adding a check to refuse loading of binary modules would only lead to a fork of the kernel, which is unproductive and unhelpful.

    If a binary kernel module contains absolutely no code from the Linux kernel in the form of headers or anything like that, the FSF would have a hard time claiming it is derivative work, thus it should be perfectly legal to distribute. The GPL may say otherwise, but this may be an over extension of the powers of a copyright holder.

      The kernel accepts binary modules by design and default. Even if the "other copyright holders to the Linux kernel" mattered in this case (they don't, see below); they submitted their code and efforts in agreement with things as they stood then, not some potential future version that Morton might want to make. So you're wrong on that point, despite any arguments they might make or political positions they might support, when the chips were down they did support kernel modules and there is no reason at all they should be illegal.

      Further, a large majority of said other copyright holders wouldn't matter if they wanted to. A contributor might have given something great and valuable to the linux kernel. Unless they're the maintainer of the portion that actually handles loading modules, too bad so sad. If I'm not mistaken that's Torvalds and Morton. Everyone else, no matter how great their bluetooth subsystem is, can no more demand linux "make binary modules illegal" than you could of Microsoft.

      Very often people characterize Linus as 'not caring about the politics' or 'being a pragmatism not an idealist.' Yet if you read his post you see that he's very much thinking about rights and freedoms. He very much does care about the freedom issue. His stance just happens to be a bit different than others (RMS for instance).

      Frequently I do not agree with Linus on issues, because his general view is to avoid meddling with things until absolutely necessary (whereas RMS, for instance, tries to think as far down the road as possible). However in this particular case Linus is dead right: putting code into the kernel for non-technical reasons, purely to limit the *end user* and specifically limit what they can do with their computer is very much "anti-computer-freedom" and should never be done.

      So Linus is effectively saying "if we do this we limit the freedom of the end user, just like the RIAA is doing with DRM..." and he is quite right.

    You have to choose exactly what level of free you want.

    The GPL has clauses in it that seek to prevent people from making it non-free. That's fair enough, but it's a compromise. You could make the licence more free by removing these clauses. That would enable others to limit your freedom. Linus seems to tend towards offering more freedom to make Linux less free.

    But does a no-binaries patch matter? Those who want to add binary-only modules are free to customise the kernel to allow this. I hope this patch remains available. choice is good.

      No, Linus very much agrees with the "quid pro quo" of the GPL. He believes that if you take his code and extend it, you should have to contribute back. He believes in sharing (even if he's not as concerned as RMS is about fundamental freedom). In the linked post Linus says:

      "If people take our code, they'd better behave according to our rules. But we shouldn't have to behave according to the RIAA rules just because we _listen_ to their music. Similarly, nobody should be forced to behave according to our rules just because they _use_ our system."

      Clearly Linus does like the GPL restricting those who would distribute code (whereas BSD causes no restrictions). The point Linus is trying to make is that we have to distinguish between limitations to distribution and limitations to the end user. The proposed patch would mostly have limited the end-user (making it annoying for them to run binary modules). Linus is saying that we shouldn't try to limit the freedom of the end-user with technical restrictions. But (as quoted above) he clearly does like the fact that the GPL forces people who "take the code" to "behave according to the rules."

      Hence Linus would not be happy with a BSD license.

    Linus has kept focus, that linux was, is and will be about technology and I agree with him on that. It is about providing wealth of options for software users. Not twisting their hand in very specific way. GPL protects linux kernel. Using GPL to blugeon other people's practices into extreme ways that GPL can be interpreted is silly.
    See there is new and old world. In the new world code is the law. In the old world it is legalese like licences, laws for real people from standpoint of non-technical point. To Linus GPL is only a way to protect kernel code, like a tool. Nothing political. Whereas for Mr Stallman it is his life and politics. For linus gnu toolkit and gcc, came with added protection of GPL. And gpl for him is exactly like a tool.

    When you are a carpenter, you don't think of societal and humane implications of using auto-nailer to a hammer. Same with Linus, his codebase is what matters first. He is driving politics from within the kernel, you might say in very meritocratic way and not from GPL and how morally conflicting it is with GPL, to load binary drivers. GPL is a cover from blatant abuse of the kernel code.

    Linus has kept focus since beginning of the project and I stand with him on that. He is a coder first, and likes to provide things and services for other fellow coders, not be meddeling in world of politics.

    Why is this bad? Separating out the kernel-space open source code from the binary blob is the only way to really ensure that the module will work with any kernel version. NVidia does it right, it works and it's binary. I don't even notice that it's not all open source because the kernel part is and compiles when I install it. Having that wrapper might not make it very fast, but it does at least WORK, and is supportable.

    I'm frankly a little tired of devices that say they are supported, when they provide a binary-only module for one specific kernel version of RedHat.

    Unfortunately, dropping binary module support in the kernel won't fix the problem. The real big players will just forward-port the support of those binary blobs into newer kernels, and now instead of just having to deal with binary drivers, we have to deal with distributions having different code support in the kernel. And who wants the commercial linux distributions to be more flexible than the free ones? Not I!

    okay in theory one cannot link any binairy blob with the kernel and redistribute it, this is forbidden by the (strong copy-left of the) GPL.
    but if Linus wants to allow this why not put Linux under a license with a weaker copyleft, like the LGPL?

    at the current situation i think the kernel devs are right when they feel the GPL is violated.

    That continual discussion on the LKML doesn't help anyone, and misses an important technical opportunity.

    Does anyone seriously believe that all card and peripheral device manufacturers will go fully FOSS any time soon, or indeed ever? No --- nobody is that unrealistic, no matter how much we'd love it to happen.

    So, since it's not going to happen, how can we best live with binary modules without suffering the many, very bad consequences of closed code being in our kernel?

    This is how:

    Find a *technical* way of containing binary modules within MMU-protected kernel domains, at the same level as the "real" kernel but with controlled/restricted access to it. This would make binary modules almost as safe as user-code but still able to communicate rapidly with the kernel resources.

    If you do that, the entire religious or political issue disappears, and instead we would have a significantly more robust/resilient kernel in practical terms.

    No more bitching. Just find a way to keep the inevitable binary modules under tight MMU control.

    It's just a shame that all this is basically the result of a really fucked up kernel design.

    The kernel right now is one big monolithic, undocumented blob of ever changing ugly interfaces that requires breaking the license if you want to add a closed source driver. There is no clear interface for any third-party work that doesn't involve the inclusion of core kernel code into closed-source modules. This design of course clashes with the reality of needing closed-source drivers for some tasks. Face it: nvidia, ATI and others are not going to open their driver sources just because a minority OS doesn't want to play with them anymore. It's really a miracle that they still are making drivers, because core interfaces are changing weekly, so instead of being little bitching whiners, be thankful for that gesture of goodwill.

    What Linux IMO really needs is a stable, well-designed external interface for such drivers. I don't know how possible it would be to create something like that, but systems like QNX suggest that it actually works. But I guess that having such an interface and actual *gasp* documentation for it would be too much to ask, especially from people who apparently don't know about the terrific capability of C to include comments in the code. It does work for other things than just the license! So far, I've only been working with three or four little interfaces in the kernel, and and each one of those required at least a week of code exploration before I could even only get to a trial-and-error phase, just because to the fact that (1) there is no or just outdated documentation in the kernel package itself, (2) the code isn't commented, and (3) all tutorials on the web are aimed at kernel version 2.2.0.

    Yes, I'm quite disgusted with OSS in general and especially Linux, but it's still less expensive than the other crap./p
