Linux Kernel v2.6.23 Released

Posted by kdawson on from the worth-the-wait dept.

diegocgteleline.es writes "After 3 months, Linus has released Linux 2.6.23. This version includes the new and shiny CFS process scheduler, a simpler read-ahead mechanism, the lguest 'Linux-on-Linux' paravirtualization hypervisor, XEN guest support, KVM smp guest support, and variable process argument length. SLUB is now the default slab allocator, there's SELinux protection for exploiting null dereferences using mmap, XFS and ext4 improvements, PPP over L2TP support. Also the 'lumpy' reclaim algorithm, a userspace driver framework, the O_CLOEXEC file descriptor flag, splice improvements, a new fallocate() syscall, lock statistics, support for multiqueue network devices, various new drivers, and many other minor features and fixes. See the changelog for details."

    overlord. welcome. yay.

    On a more serious note, are these improvements dramatic, or is story featured just because it's the newest Lolnus kernel?

      On a more serious note, are these improvements dramatic, or is story featured just because it's the newest Lolnus kernel? I don't know about dramatic, but the change does replace several core OS components, some of which generated quite a bit of buzz when development was first announced (too lazy to link some of the flame wars^H^H^H^H^H^H^H^H^H^H discussions that news of a new scheduler generated).

    I think I'll take the opportunity to upgrade to 2.2.26; I don't waste my time with unproven technology.

    Yes, what they don't mention is that the XEN "guest support" is in the form of a crowbar.

  5. Re:Answer: Linux will never be GPL3. by BadAnalogyGuy · · Score: 5, Funny

    Hello everybody out there using Linux -
    I'm doing a (free) operating system based on GPL3 (just a hobby, won't be big and professional like Linux) for x86. This has been brewing since april, and is starting to get ready. I'd like any feedback on things people like/dislike in Linux, as my OS resembles it somewhat (same physical layout of the file-system (due to practical reasons) among other things).

    I've currently ported bash(3.2) and gcc(4.2.2), and things seem to work. This implies that I'll get something practical within a few months, and
    I'd like to know what features most people would want. Any suggestions are welcome, but I won't promise I'll implement them :-)

    PS. Yes - it's free of any Linux code, and it has a multi-threaded fs. It is NOT protable (uses 386 task switching etc), and it probably never will support anything other than AT-harddisks, as that's all I have :-(.
