    The "comprehensible changelog" [kernelnewbies.org] is slashdotted. Why is the high-level feature list of the release such a low priority, though so demanded? I know programmers prefer writing C to writing English (or Finnish, or Hindi, or German). But what good is code people don't install because they don't know what it does for us? There are so many people hanging around OSS projects who can't or don't contribute to the code. Surely some of those people can help by at least distilling the changes into a brief description. Release notes might not be the most important product of a release cycle, but they often control everything that product consumers do after the release is published.

      • Numa-aware slab allocator: It creates slabs on multiple nodes and manages slabs in such a way that locality of allocations is optimized. Each node has its own list of partial, free and full slabs. All object allocations for a node occur from node specific slab lists (commit - benchmarks) [kernel.org]

      • Lazy page table copies in fork() for VMAs without anonymous pages (the ones with anonymous pages are still copied): Defer copying of ptes until fault time when it is possible to reconstruct the pte from backing store, speeding up fork() greatly specially for processes using lots of shared memory (commit) [kernel.org]

      • Add /proc/$PID/smaps: This file will shows how much memory is resident in each mapping. Useful for people who want to perform memory consumption analysis (commit) [kernel.org]

      • Add /proc/$PID/numa_maps: This file will show on which nodes pages reside (commit) [kernel.org]

      • Lock-free file descriptor look-up (commit) [kernel.org] - (commit) [kernel.org]

      • Four-level page table support for the ppc64 architecture: extends the usable user address range to 44 bits (16T). (commit) [kernel.org]

      • Support hotplug cpu on 32-bit SMP powermacs: When a cpu is off-lined, it is put into sleep mode with interrupts disabled. It can be on-lined again by asserting its soft-reset pin, which is connected to a GPIO pin (commit) [kernel.org]

      • Add TASK_NONINTERACTIVE task state bit to the cpu scheduler: It can be used by blocking points to mark the task's wait as "non-interactive". This does not mean the task will be considered a CPU-hog - the wait will simply not have an effect on the waiting task's priority - positive or negative alike (commit) [kernel.org]

      • PPTP (Point-to-Point Tunneling Protocol) support: RFC 2637 [ietf.org]. Used to implement VPN products (notably, Microsoft in all the Windows versions). Wikipedia article [wikipedia.org] (commit) [kernel.org]

      • You're using the wrong definition of "consumer" - too narrow. People consume kernels whenever we install them, even when we're developers, or even kernel committers.

        True, but building your own kernel isn't particularly challenging either. Basically if you have installed your GCC compiler and a couple of extra packages then as long as you can follow a recipe you can probably build a reasonably good kernel tailored for your system.

        Running LILO is probably the most dangerous part, because if your config file isn't right you can leave your system unbootable. A much better option is taking the time to learn GRUB and get it installed because once it is installed all you have to do is add a couple lines to a text file to add another kernel to the list. That way you just leave your existing kernel hanging around until you get your home-made one perfected. It usually takes me a couple of attempts to get a new kernel compiled to my satisfaction.

        I don't upgrade my kernel very often either. Once I get a stable system that runs well and has all my drivers supported I usually keep that kernel for a year or so, unless I'm feeling bored and just want to play around with the latest and greatest for fun.

        • can grub do a boot configuration once like lilo can.

          boot configuration once is a very handy feature if you have a remote powerswitch but no other way of getting at the machine until/unless networking comes up.

        • add a couple lines to a text file to add another kernel to the list. That way you just leave your existing kernel hanging around until you get your home-made one perfected.
          LILO's the same way, dude, no difference. In fact, I do that with Debian-installed kernels so I can be sure they're clean. I even have Memtest86+ in the list too.

          There are two main reasons to run GRUB. The first is because you can build new kernel start lines on the fly. LILO has to be hardcoded with kernel locations on disk. You can change the boot parameters, but you can't start random kernels. GRUB, on the other hand, understands enough of the filesystems on which it lives to allow you to boot arbitrary kernels on the fly.

          The second reason (closely related) is that if, for some reason, the kernel files move around on disk (did you just restore from backup?), LILO blows up, and GRUB just works.

          Either bootloader can be used safely to remember multiple different kernels for routine experimentation.

        Linus won't order it in since Andrew Morton (his right-hand man) has already indicated that it will go in. There are a few concerns raised by Christoph Hellwig (lkml's resident pitt-bull) that Andrew Morton has asked to be fixed before it goes into vanilla. Mostly these issues have only held up inclusion (a filesystem would normally have got merged with just those style issues) because of concerns that after inclusion the code would be abandoned and even cleanups being opposed by the original developers as allegedly happened with reiser3.

        features and performance are *not* the top priorities in Linux, the top priority is maintainability. The rate at which features and performance improvements are added is a consequence of the maintainability, which must not be compromised for the sake of a slightly cool filesystem.

            The vfs already has modularity, and the vfs is *the* Linux filesystem where the filesystems are modules that implement separate storage backends but all the same semantics.

            One problem with reiser4 (now addressed in the code proposed for inclusion at this time) was that it changed some of the defined semantics of the vfs. This bit won't go in until it is thoroughly discussed and user-space has subsequently been prepared for it (and deprecation of the old behaviour widely expected).

            The problem with the modularity of reiser4 is that is implemented fully inside reiser4 instead of being designed as a modification of the vfs where reiser4 simply provides one storage backend. The reiser4 modules should have been put right up behind the vfs as a proof of concept for the first integration, where the new modularity features could be moved bit-by-bit into the vfs, where all filesystem are then just a storage backend and all could be easily made to support the transaction and query facilities expected.

            Some of the style problems included things like generic datatypes being implemented in the reiser4 directory instead of as a general facility for the kernel as a whole. Most of these were fixed, I believe, but AFAIK the problem of the level at which the modularity is implemented, and the failure to distinguish between semantic/feature modules and storage backend is not a good design.

          Reiser3 is FAR from abandoned by Namesys. Anyone can post patches to it and get them in the kernel, Hans has no control over that, and it has been proven because SuSE developers have gotten patches in to the kernel against Hans wishes.

          ReiserFS3 is "version 3" of the Reiser filesystem. Hans wants it to be deemed "stable" and free from new FEATURES, and only bug fixes be applied. Any new features he wants to put in the next version of ReiserFS, v4. Rarely do you see MAJOR features from Kernel v2.6 being backported to v2.4, there is reason for that, because with features comes bugs.

          For some reason people consider this to be abandoning Reiser3. When it is quite the opposite.

      A lot of things that the "average user" takes for granted are supported by features in the kernel that they didn't know even existed.
      A lot of things that Linux *applications* need to do require kernel features that need to be implemented.
      Take all the new search utilities (Beagle et al.) for example, they are depending on kernel features like "Inotify". If you read about Inotify you probably wouldn't give a damn, but you read about Beagle and then understand the point.
      Same goes for other types of features, like more secure/reliable filesystems. Sure the average user "doesn't care", but he sure cares when that feature wasn't implemented and he ended up losing half his work to a crash.

      Besides, one of the biggest complaints about Linux is that when a brand-new application comes along that requires a user to "patch and recompile the kernel", it's *too hard* for the average user. So be happy when these features become included by default.

      (note: I'm no expert on the linux kernel) Yes and no. Much of what is left to be done in linux kernel has to do with proprietary devices. However, these things are not in the category "cannot be fixed." In fact, OSS developers constantly reverse-engineer new devices and standards, and get them working properly. It is hard, but can be done. For instance, this release includes enhanced support for Centrino, which is a standard for wireless connectivity (in laptops, etc.). Just because companies do not release specs does not mean that the linux kernel cannot include support for them. It is very very hard, but somehow they manage to do it!

      And in a broader sense, the kernel is never "done" because computer hardware and software is constantly evolving, and thus the kernel must constantly evolve to meet modern demands. Yes, a 10-year old kernel will probably run your web server just fine, but the newer kernel versions integrate much better with newer hardware technology.

        I just meta-moderated a troll as unfair, which I usually do, by the way. Just because a moderator disagrees with a post does not make the author of the post a troll.

          One of the problems is that there isn't a mod for "wrong". So if you encounter a post which is just obviously incorrect, how do you mod it? Overrated, troll, or flamebait are your only options..

  • Great for klik and go applications (Score:3, Interesting)

    Well, this new kernel is great news for the http://klik.atekon.de/ [atekon.de] service which allows you to directly run the latest experimental linux applications or stable debian packages in a user account by just clicking a link to run and install without messing up your installation (just like selfcontained Apple appliction folders).

    The mounting of file systems without root permisson means klik will become even easier to install on linux distributions. And it already runs on several distributions without configuaration.

      Sorry - this isn't the MPPE patches. This is support for PPTP packets being tracked through iptables. What I believe this will let you do is have multiple PCs behind a Linux firewall be able to use PPTP at the same time (prior to this PPTP through a Linux iptables firewall would work for only one PC at a time.)

    If these work, this is BIG news. IMHO these make Linux into a completely new operating system, not just a Unix clone. Everything a computer process can think about should be named in a single hierarchial namespace. Until now all operating systems except Plan9 have been bogged down by concepts that think that only blocks of bytes on a disk are eligable for this naming scheme.

    Expect vast numbers of FUSE programs. In the future I expect *most* non-trivial programs to actually be FUSE programs.

    This is great, now that HostAP and Centrino are in the kernel. We've needed this to be in the mainstream kernel for some time. But Atheros support is still missing, and it's just as important, if not more important, than either of those chipsets. Most people are aware of the MadWifi drivers with closed-source HAL (i.e. part of the driver is closed source), but there's also a project by OpenBSD to make a completely open source driver for the Atheros cards, called OpenHAL. It's been ported to linux: http://cvs.pdos.csail.mit.edu/cvs/roofnet/release/ openhal/ [mit.edu] - but needs testing. Please work on it!
    • I was under the impression that ipw2200 drivers still required a binary-only module to operate. Has this been changed, or do 2.6.14 kernel users just need to download that module now (rather than the whole driver package) in order to have a functional wireless card?
  • that track which versions of the linux kernel are affected by which vunerabilities are fixed in what kernel versions? i'd like to know what kernel versions need to be upgraded or patched (and what to patch them with) to maintain a secure system.
  • Got myself a Promise Tx4000 card last week and was surprised that kernels before 2.6.13 didn't support it fully - the card was detected but the ATA disks weren't. I called the supplier and they gave me the 'linux not supported - buy at your own risk' speech. I was about to give up when I discovered that the latest kernel 2.6.13-rc5 (now 2.6.14) finally added support for the ATA channels on this card.

    Thanks. It's much appreciated.
