No 2.7 Linux Kernel Branch Due Soon 447

An anonymous reader writes "At the fourth annual Linux Kernel Developers Summit, it was decided that there won't be a 2.7 Linux kernel development branch any time soon. Instead, Linux creator Linus Torvalds and the official 2.6 maintainer Andrew Morton have decided to continue working as a team, further enhancing the 2.6 kernel. Up to this point, kernels ending in an odd number (2.1, 2.3, 2.5, etc) were considered development kernels, and kernels ending in an even number (2.2, 2.4, 2.6, etc) were considered stable kernels. However, according to this KernelTrap article, active development will now continue in the mainline 2.6 tree, and the final stabilization will be left up to the companies that provide Linux distributions."

      I was thinking the same things, but there's a bit of ambiguity in what is meant by "stable." I think they may have meant code stable, not OS stability.

      That said, it could be a good thing to preempt the distros from forking in order to add new features that they do not want to wait for, and it also adds the benefit of Linux providing the OS features that you want ASAP, not in 2005, err, maybe 2006, 2007 or 2008 when the next major release is planned-- that would be the Longhorn development model.

This goes against the whole idea of Free Software. The idea is to make a working, useful product, not half-baked cripple-ware that you then have to pay someone to fix. I understand the concept of paying other people to "add value" i.e. enhanced features, but I don't regard stability as an "enhanced feature." A lot of people who don't alread run Linux (but maybe Windows) will now have one less reason to change and one more piece of FUD to beat the Free and Open Source Software movement with.

      Come on. No major distributions except Slackware ships with a plain vanilla kernel. "All" distributions patch their kernel (based on a stable relase) more or less heavily, sometimes resulting in problems, see for example here [talkroot.com] or here [kerneltrap.org].

    The 2.6 linux kernel has been a roller coaster ride of development, and it was obvious from the switch from 2.5->2.6 that the kernel was far from ready for prime time.

    So, now we're stuck with a rapidly developing 2.6 kernel that poses a lot of risks for anyone wishing to adopt the new so-percieved "stable" kernel into an OS/Embedded/Other product.

    In a way, this is just an acknowledgement that things went a bit too fast with 2.6, and that waiting to release it -after- some pretty solid core feature freezes would have been good.

    There is still a lot of development and teething going on, and it's going to be a real pain on the part of "third party distributors" to find and use whatever build-of-the-week is more stable than another in a given sub-branch of the 2.6 kernel.

    Oh well, so much for having a nice stable 2.6 base to build new functionality into.

There's a new kernel! We should try that!" There's NOTHING wrong with the current odd-test/even-stable scheme. If Linus and Morton want to play around with new features, MAKE A 2.7 BRANCH! 2.6 is finalized, let it be! If you don't think that there's enough features in it, YOU SHOULDN'T HAVE RELEASED IT!

    A lot of people use the vanilla sources, myself included obviously, I should have to go RedHat to get a working kernel. The 2.6 branch is NOT a playground, that's what the -mm branch is for.....

    2.6.6 works for me, and I'm not changing. For the first time in my life, I *DON'T* trust what's coming from Linus & Co.... and that's scary.... It's like God is forsaking you to go play with some toys....

      I'm sorry your forcedeth driver example is harsh. The driver is clearly labelled as "EXPERIMENTAL", and what's more it is *reverse engineered* because nvidia didn't want to give out the documentation to it. You are lucky someone was actually working on it at all.

      As a sidenote, nvidia is now actually contributing to this very driver, however that has been since 2.6.7.

      So this line of argument holds no water.

    We can no longer count on the bare kernels to have any stability and depend on companies to stabilize the kernel.

    I disagree with this method for a few reasons.

    Everyone still probably remembers when you had to use a bare kernel to recompile and get Nvidia HW Accel drivers to work with the 4k stack problem.

    Also this will pose a problem with many distro's that do not have armies of people to sit around and stabilize the kernel for their distro.

    Another problem is with drivers being fixed. A bare kernel will be fixed but the customer may have to wait 2-3 months before their specific distro comes up and included a fixed kernel.

    Lastly this will increase costs for developers of distros such as Redhat and Novell due to them having to now employ kernel hackers to deal with problems that may exist in the Kernel.

    I can see no good coming from this approach to Linux and may hurt us in the long run. I hope they reconsider.

    However, according to this KernelTrap article, active development will now continue in the mainline 2.6 tree, and the final stabilization will be left up to the companies that provide Linux distributions.

    No sane person will now touch 2.6 tree for a production server knowing that developement is the 2.6 tree, unless they buy from RedHat etc who may guarrantee stability

    Lets hope they reconsider and create 2.7 ASAP otherwise I know some companies will probably want to either stay at current release, or abandon Linux ({cough} some may even go back to Micro$oft)

    Even "production" kernels can have problems. Remember the VM changes around 2.4.10?

    New productions kernels deserve every developer's full attention until they're really really ready.

  • The only thing that really upset me here was the offloading of stabilization to distros. What about distros that don't have a huge developer army (Slackware for example). Before this the vanilla kernel was actually useable. I wonder if this will make it less so. OTOH 2.6 isn't really feature complete quite yet. Some things like LVM2 still are missing from 2.6. So I guess I don't mind feature additions as long as they don't destablilize the main tree, thus requiring distros to use a non-vanilla kernel. On

    To everyone saying this will kill the independent distro, chill.

    If you were going to make a new distro right now, in my opinion you'd be better off starting with Fedora or Progeny's Componetized Linux or vanilla Debian or something as it is, stand on some shoulders people. Linus and his crew produce a kernel, not an operating system, I'm sure they're doing this to produce the best kernel they can, not because they hate you.

      That is entirely contradictory; active development should not exist on a STABLE branch to prevent any unforeseen stability issues when introducing new code, ideas, and features.

      On a STABLE branch you only want bug and security patches. People are very realistic that stable (even) Linux kernels have had serious issues, but introduc

    • So? Nobody's talking about creating a new distro. We're all thinking about existing distros that don't have the manpower to ensure that their system is properly tested with each new feature of each kernel release. Taking the time to do so means less time for adding and testing new applications and user-level features, the stuff which many more people care about.

      Only when Linus was the maintainer. As soon as the kernel was handed over to Marcelo Tosatti, 2.4 got SIGNIFICANTLY more stable and development slowed to a crawl. Many peoples point is that 2.6 will never be anything but early 2.4 because Linus refuses to leave it behind and start something new. I blame a lot on Andrew Morton. M

    It seems to me that everyone is assuming that there will never be a 2.7 tree. From the article [kerneltrap.org], the simply quote Jonathan Corbet as saying that "2.7 will only be created when it becomes clear that there are sufficient patches which are truly disruptive enough to require it. When 2.7 *is* created, it could be highly experimental, and may turn out to be a throwaway tree."

    They are just concentrating on the stable branch for now, and collecting a patch set (Andrew Morton's -mm patch set, that is) as a testing ground for proposed (stable) kernel changes.

    This really doesn't seem like a big deal, and it implies that the kernel people will focusing on stability for the time being.

    IMHO this is bad. If the development process can no longer isolate between what's stable and what's under development, then they probably are incapable of measuring the stability of the current release product.

    But I wonder how Debian and Gentoo will handle this since they aren't the stereotypical Corporation who stabilizes the kernel prior to release. Debian at least, does a very slim job of customizing the Linux Kernal when compared to RedHat, Mandrake, and SuSE.

    Does this imply that the LKML has decided to abandon their origins of Free and just hack code and let someone else actually worry about a finished workable product? Sounds like they are kind of blowing off their community.

    Or is the community filling up with whinnie-assed whimps who don't know what the meaning of "make clean" means?

    I've been constantly amazed by people imagining that version numbers on the Kernel, (Or other software for that matter) actually reflect anything other than a simple fact: A build at a point in time.

    Read the kernel mailing list. Sure, as a version approaches, Linus makes an attempt to not include patches which have not undergone much testing, but the simple fact of the matter is that the Kernel is no less or more stable at 2.6.n version as it is in version 2.6.n-mm4, or 2.6.n-rc7 etc...

    Versions in the kernel are really just "points in time" The apparent stability of a version is really perception as to what is working or what isn't, and is completely outside of the versioning.

    What's worse, in order to facilitate the versioning mechanism, Kernel maintainers have moved closer to the 2.n.m-rc1234 bla bla bla in order to signify that the whole number m is "stable", which, just as often it isn't quite, and requires patches anyway.

    Honestly, for my money Linus could either use 2.6.n.20040722 to signify his builds, and I'd be just as happy.

    Aside notes:
    For those who used the 2.5.xx series and found it unstable, Did you report what unstability you had?

    For those who tried the 2.6.xx serise and found unstability, did you report what unstability you had?

    I think that when you claim that a version is unstable, you should back it up with what is wrong, and how it affected you, and pass that information forward to the developers. If you don't, you are robbing the developers of the very feedback they need. Complaining about it doesn't do much good if they don't know about it.

    This decision scares me. I believe that this will create pressure that will lead to one of two things:

    • Kernel fork so that companies can have a stable branch that they can trust, and just cherry pick new things from the main tree as and when they want
    • OR - vendors like Oracle, Sybase, IBM, etc. only supporting one or at most two distributions
    Before you shout me down, hear my reasoning out...

    Vendors developing applications need stable APIs and ABIs. We're already too close to a potential fragmentation situation with multiple distributions on different kernel versions, glibc versions, etc. It's giving vendors headaches because they claim to support Linux, but then the masses spew insults when their particular distribution doesn't work.

    Ignoring performance stability, instability of the code base will hurt Linux acceptance. If it costs vendors more to keep up with the ever-changing world than they can make from selling Linux solutions, they'll either find a way to freeze that world (i.e. fork), or they'll discontinue or reduce their support, and tie it to just one or two distributions. These are both bad options for the end-user.

    You also have to wonder how much trust should be placed in the distribution companies. Going for a Red Hat solution is in many cases more expensive than a similar Sun solution, and Red Hat don't provide a lot of choice. Want to use XFS or JFS on your Red Hat Enterprise Linux AS 3 server that you paid them $1000 for ? That's just tough, because if you do that, they won't support the box.

    Pay a grand and get no support - that's the price of 'choice' with Red Hat. I'm sure other distribution vendors will be the same, because at the end of the day, they need a known-good installation to troubleshoot against. That's fair enough, they're in this for business reasons. But to say that we should rely on their altruism for our stable kernels ? Doesn't seem like good forward thinking to me!

    I can think of no other words for it.

    While I have no problem with them making patches in 2.6 for security reasons or to do bug fixes or corrections, the dev branches have been traditionally an opportunity for the kernel devs to tinker and to begin adding newer and cooler features to the kernel. One could rely on the fact that in a linux kernel numbered x.y.z, that if the only thing that changed was the z, one could usually reasonably expect that nothing significant would be changing within their system. That if they upgrade from x.y.a to x.y.b, the only things of note will be bug fixes, security fixes, and _MAYBE_ a minor feature or two that 99.99% of the people wouldn't notice anyways, but nothing too significant will have actually changed unless it was previously broken. However. now they want to make 2.6.x a development tree and I can see that this could have one of two negative consequences:

    1. Addition of new features to linux is slowed down drastically, in order to keep the feature set in 2.6 as consistent as possible. With no 2.7 to put new features into, there's not much breathing room for creative development.
    2. The devs won't have a problem adding new features to 2.6, creating a high diversity in the 2.6.x feature set. This can cause some level of distrust in the 2.6.x branch, just as there has usually been in most of the previous development kernel versions, and this would slow down its acceptance and use.

    In other words, not having a 2.7 is a Bad Thing. Why they don't see this is beyond me.
