Torvalds vs Schwartz GPL Wars 335

Posted by CmdrTaco from the which-one-is-han-solo dept.
javipas writes "The controversial message published by Linus Torvalds (mirrored) in the Linux Kernel Mailing List was from the beginning to the end an open attack to Sun and its Open Source strategy. Linus criticized Sun's real position on GPL, and claimed that Linux could be dangerous to Sun. Upon his words, "they may be talking a lot more [about Open Source] than they are or ever will be doing." Jonathan Schwartz's blog has been updated today with a post that is a direct response to Linus claims, but in a much more elegant and coherent way. Sun's CEO notes that "Companies compete, communities simply fracture", and tries to explain why using GPL licenses is taking so long."

      Good point. It's definitely interesting. I think sometimes it's good to see science and engineering as human pursuits, but even when it may look like the spittle is flying across with the packets, these are just two intelligent guys with differing points of view who would probably buy each other a beer when they're done for the day.

      Even Linus and Andy Tanenbaum respect each other, I think. Otherwise they wouldn't care what the hell the other thought. The verbal fencing is just nerdy snark at DEFCON 2. If you can't read "You would've failed in my class" with a chuckle, then you've been watching too much politics on TV. Linus would've wrecked the curve in Tanenbaum's class. He didn't design a monolithic kernel structure out of ignorance; he had a goal, and he thought that was the best way to go about it.

      I wouldn't quite say "nothing to see here"...but there's no actual malice. These are two guys who are smarter than I am; I read what they think and why, and am smarter for it on both sides.

        Hindsight's always perfect. Do you really expect Tanenbaum would have had any qualms about letting him fail if Linux had been a class project, with no actual real-world use? I don't think he would've just done so right away without giving Linus a chance, but it would've been mild coercion at best - the "I'm the professor, trust me, I know what's right and wrong, so why don't you change your design now, son, you'll get a better grade that way... after all, I *am* the professor, and I control your grades, if you catch my drift" kind.

        So without any actual proof (or even evidence) that Linus' design was solid, he certainly would've failed. And even now, I don't think that Tanenbaum admits that monolithic or hybrid kernels (because let's face it, Linux isn't 100% monolithic) are actually better; the most you'll probably get out of him is "yes, they're being used widely, and they haven't failed catastrophically, but microkernels are still be fundamentally better".

        He's a zealot, basically (and I don't automatically mean in a bad way - he's just a zealot the same kind that, say, RMS is a zealot), whereas Linus is a pragmatic engineer (he sure has some strong opinions, too, but he can always back them up and he's willing to change them if presented with convincing evidence that they're wrong). That's the fundamental difference between the two, and it's also why Linus would've failed if he had been in Tanenbaum's class and if he hadn't changed his design according to Tanenbaum's wishes.

        That being said, to not make this an entirely off-topic post, keep in mind that Schwartz is not an engineer, either. He wants to sell you a product - nothing more, nothing less.

I am no fan of sun (although since GPLing Java I am starting to lean that way, I admit), but his reasoning in the post for several things (licensing choices of Solaris, relationship to Linux, etc.) makes a lot of sense.

          This is fascinating. It seems to me through the number of references in Linus's post to ZFS that he (or at least members of the kernel team) are drooling over it. This is all actually working quite the way RMS intended. Linux may be a GPLv2 stronghold, but as soon as some piece of GPLv3 software comes along which is a *must have* i.e. ZFS, enough pressure will fall on the major copyright holders that they will consider going through the PITA of upgrading the kernel to GPLv3.

          That may be the major reason for Linus's striking change of heart on GPLv3.

          You have to wonder whether RMS talked to Sun at all about this. We do know that he has praised the company for the decision to GPL Java. If RMS wanted to strongarm Linux into a license change, what better way to do it than through ZFS?

      • What exactly is not well thought out about his comments? Incendiary? Which part?

        The whole thing?

        first off: they may be talking a lot more than they are or ever will be doing.

        This is incredibly unfair given that Sun has released OpenOffice, Java, NFS, major GNOME improvements, Solaris, SPARC, and a variety of other significant items into open source. While Sun struggled for a while before they got it right (they were hesitant to give up their favorite lawsuit club for beating Microsoft over the head), they did eventually embrace true OSS licensing.

        While I understand his frustration with Sun's glacial pace, he needs to remember that Linux usage would be nowhere near where it is today if not for several key contributions by Sun.

        they sure as hell don't want to help Linux.

        Similarly not fair and incendiary. Yes, Sun has their own operating system. But they also sell a lot of Linux servers and even tried jumping on the distro bandwagon for a while. Again, Sun is having a lot of difficulty rationalizing the two different OSes. But that does NOT mean that they are hostile toward Linux development. Open sourcing Solaris isn't so much as an attempted coup (IMHO) as it is a rational attempt to find a middle ground between Sun's existing codebase and the Linux codebase.

        they'll not be releasing ZFS and the other things that people are drooling about in a way that lets Linux use them on an equal footing. I can pretty much guarantee that.

        I'm fairly certain that Linus will be eating those words in the future. ZFS is already under the CDDL license, which means that it can be included by distributions already. Just not folded into the core code. I'm certain that this will change with time, and that the CDDL will eventually be eschewed in favor of the GPL. Sort of like Sun's 500 licenses for Java before they finally got where they were going.

        See the OpenSolaris stuff - instead of being blinded by the code they _did_ release under an open source license, ask yourself what they did *not* end up releasing.

        Ok.

        Q: Self, what did Sun not release under OpenSolaris?
        A: Oh, that's easy self. They didn't release any code encumbered by previous licensing problems and/or someone else's trade secret. These components are the reason why most companies refuse to OSS their software even after they have no use for it anymore. Sun took a different approach and cleaned the codebase before release. They had the same problem with releasing the Java2D and JavaSound implementatons under the GPL. They were unable to release these components because they were owned by Kodak and Dolby respectively.

        Yes, they finally released Java under GPLv2, and they should be commended for that. But you should also ask yourself why, and why it took so long. Maybe it had something to do with the fact that other Java implementations started being more and more relevant?

        This is just plain hubris. Anyone who has spent time in the Java community knows why Sun was so difficult about releasing control over Java: Microsoft.

        Microsoft tried the whole Embrace, Extend, and Extinguish with Java. The only thing that saved it was Sun's legal department. It wasn't until MS was fully committed to their COOL project (ni, .NET/C#) that Sun felt they were in the clear. So they slowly released it, with a strong eye toward potential forking and incompatibilities. And to be perfectly honest, Sun never understood why the community wanted their codebase so badly. But the community pushed, and Sun eventually gave in. (Primarily due to Schwartz's leadership!)

        FWIW, I've worked with Sun several times. They really do work hard to be helpful, but they are also very methodical about it. For example, when the primary maintainer of a Linux distribution and I got in an argument about whether or no

    People are perhaps reading to much into it. Linus advanced some scenarios, while at the same time giving his reasons. He was blunt, in his style, about some things but I don't see it as an all-out attack on Sun. Even more interesting is that he says that he could be wrong, and that he hope he is wrong, and that releasing Solaris under the GPLv3 would be a very good thing.

    Also of note is Theo's de Raadt message in Sun's blog: "Jonathan, I wish the above was true. 15 years ago I was the biggest Sun fan. Today I speak as the project leader for another set of open source projects -- OpenBSD and OpenSSH. OpenSSH will be better known to your audience, as it is what they use daily to connect securely to and from their Solaris (or Linux) machines. OpenSSH killed telnet and rlogin, for those who still remember those mechanisms. We give our software completely freely to the world, without even the standard encumberances people see in the GPL or CDDL. Yet when we turn around and ask Sun to give us documentation for the chips on their machines -- chips Sun themselves designed, not via contractors -- Sun drags their feet. Recently we tried to reopen these 10-year-old repeated requests, and once again nothing positive happened. You may remember, because you and David Yen were in an email conversation with us. Lots of nice open words were exchanged, but no action. However, let me give an example of the duplicity of Sun. (I wish I could use a lighter word). Two operating systems run on Sun's latest PCI-e based (smallish) Ultrasparc-III machines, the v215/v245 -- Solaris and OpenBSD. The latter system runs on those machines because the code to support the non-processor chips on the board had to be written after painstaking reverse engineering, because Sun refuses to make available documentation for how these chips are programmed. Now we will readily admit that not every programmer in the world needs to know how to program these chips. But does every programmer in the world need to know how to program every little detail on Sun's processors, in system mode? Sun gets great press out of UltraSPARC being all "open", but what use is supervisor-mode documentation when the rest of the chips that the supervisor-mode code has to communicate with are entirely undocumented??? The press does not spot this problem, but Jonathan, you should clearly understand this is a fallacy. There are two operating systems which surprisingly do not run on the Sun v215/v245 -- Linux and OpenSolaris. OpenSolaris?? Yes -- Sun isn't even open enough to give the OpenSolaris community enough documentation to support their new machines. So I think that Linus is right, and Sun has a long road ahead."

    I tend to listen to Theo's opinion carefully on this subjects. I'm an "FSF fanboy" to the bone, card carrying and all, which curiously is one of the reasons I tend to view Theo's opinion on this subjects with interest, more so than Linus. When it's not a GPL vs BSD thing (which is a fait-diver discussion in my sense of priorities) the fact remains that he seems to see the problems with licencing with a greater depth and in general is more "idealistic" than "pragmatic".

    To my mind, the relationship between Sun and Open Source has always been coloured by Sun's Big Thing: Java.

    As a development platform, Java only had one new thing to offer. Perl, Python, PHP, C et al. are "write once, run anywhere" languages, as long as you publish the source. Sun's contribution is a language that supports "write once, run anywhere" without publishing the source.

    In other words, Sun's most interesting contribution to the software industry is a powerful (if painful to use) tool for distributing proprietary closed source applications.

    I keep wondering whether they just stumbled into this or whether it was a strategic move. In either case, it's hardly a testimonial to Sun's support of Open Source.

    • Not a valid argument as you can put out vm bytecode for perl, php, python, ruby too (either finished vm or one in active development led/supported by language's creators)

      • True enough, but vm bytecode for for those languages wouldn't have an audience; the developers didn't advertise a WORA system and make the vm available to everybody's grandmother.

        Does anyone who isn't a php developer know how to get the vm only for php?

        Sourceless distribution is possible for these languages, but it's rare, and not the intent. In the case of Java, sourceless distribution is the intent, it's common, and Sun has made sure the vm is on every machine.

      I'm no big fan of Java, but allow me to point out that GNU's biggest contribution to the open source world is arguably GNU C and glibc, which just as much aren't designed as vehicles for publishing source (i.e. what interpreted languages, well, unlike, say, Microsoft BASIC, Perl and Python are technically bytecoded too, but humor me.) Considering the environment that Java was originally marketed for (browser apps) there are good security, portability, as well as performance reasons more relevant at the time, for making client-side browser apps pseudocompiled.

      Single-threaded SPARC performance is for shit. Niagara gains its power from parallelism. If your task isn't parallelizable then it runs like dookie.

In fact it's better than on Intel / AMD in that it's always the same. ie - it runs the same speed, regardless of load. It's throughput, not race to the finish, with long waits in between. I've had horrible experiences with RedHat in particular, with modern, patched up versions blowing chunks due to patches loading, breaking either itself or other software on the system.

          "runs the same speed" regardless of "load"? Could you please use some technical terms here? x86 instructions complete in a given number of cycles (barring branch misprediction, to which SPARC is not immune) so intel/AMD chips also always run at the same speed (barring throttling.)

          They aren't making Solaris look like Linux, they are however, making Solaris cross platform (Sparc/AMD/Intel)

          *cough*bullshit*cough* As a newborn Sun employee, Murdock is thinking about making Solaris more Linux-like [zdnet.com]. "When people say Linux what do they mean? Linux is a kernel. Cool apps are not written to the kernel. The OS powers higher levels of the stack. What we want is an open OS platform and to make sure that the existing skill sets and knowledge and training investments are leveraged. We don't want to make them learn a new product or rip and replace," Murdock said. "You can make a real argument that Solaris innovated more than Linux in the last few years--such as DTrace and ZFS--but usability stands in the way of appreciating that," Murdock said. "Part of what we are working on is closing the usability gap so that it doesn't stand in the way." (next para, emphasis mine:) "There is no reason we can't make Solaris look and feel more like Linux," he continued. "There are a couple of ways we could do it. We could stick a penguin on it or take a Linux distribution and put a Solaris kernel in it. There are a few Solaris-based distros that have done that. Personally, as the person charting the course and looking at the strategy question, it becomes how to keep the competitive differentiation of Solaris while closing the usability gap."

          Perhaps you should try to be informed before you attempt to refute my statements? Especially since you're wrong.

          Also, it's worth noting that there's Sun SPARC-based hardware that OpenSolaris doesn't run on, because Sun won't give out sufficient specifications. Theo's way of putting it [kerneltrap.org] was "Sun released CPU docs, but that's useless. It is kind of like trying to fix a car engine with the owner's manual. The rest of the hardware is not documented."
