What's New in Linux 2.6.39: Ding Dong, the Big Kernel Lock is Dead

This release brings new features, new drivers, and one big accomplishment: Ridding the Linux kernel of the Big Kernel Lock. The Big Kernel Lock was almost removed in the 2.6.37 kernel. That is, the kernel could be built without it — but some of the code was still there. With the 2.6.39 kernel, the BKL is finally gone with a patch from Arnd Bergmann. This has been a long-running saga, and LWN has some good coverage of what the BKL is (or was) and the effort to get rid of it.

But what else is in the new kernel? Improvements and New Features. Inside the Linux Kernel. One of the highlights of the Linux Foundation Collab Summit's program on Wednesday was the panel of kernel developers discussing issues of kernel development and fielding audience questions.

Inside the Linux Kernel

Though fairly unstructured, the panel provided an engaging peek into the world of the kernel for those of us who aren't involved in day to day development. The panel included James Bottomley, Andrew Morton, Thomas Gleixner, and Arnd Bergmann, and moderated by Jon Corbet of LWN. Bottomley is a distinguished engineer at Novell and SCSI subsystem maintainer. Morton is the memory management subsystem maintainer.

Gleixner manages bug reports for NANA flash, core timers, and x86 architecture. One of the first topics was the current problems with the ARM architecture, which is sort of a embedded wild west at the moment. Another challenge, is that developers now working on Linux at the behest of their employers are often developers who worked on "black box" operating systems. Catching Up to Hardware Linaro.

It's Official: Linux 3.0 Released

On Thursday, July 21, Linus Torvalds put a stake in the heart of the "bignum days" for the 2.6 kernel and took the wraps off Linux 3.0.

Linux Turns 20 Today — And Shut Up, Yes, It Still Matters

Linux is just for nerds. Not mere nerds — we’re all nerds — Linux nerds. It’s a hobbyist OS for contrarians. It’s an antique. An oddity. Linux started off humbly enough — just some guy, some programmer’s side project. August 25th 1991 – Linus posted the following to comp.os.minix (a usenet newsgroup): I’m doing a (free) operating system (just a hobby, won’t be big and professional like gnu) for 386(486) AT clones. Yes, this is mostly programmer gobbledygook. Your Android device? Your TiVo? The New York Stock Exchange? Google something. That ATM you withdrew cash from last night? And of course, there is the tremendous number of servers powered by Linux that run the websites you frequent daily. A Happy Birthday Linux Post Written By A Linux Script.

So we turned the mic over to a custom-written Linux script running on Ubuntu to let the OS to talk a little about itself on this special day. ^ a b Linux 3.0-rc1, Linus Torvalds, 30 May 2011, accessed 31 May 2011 Previously there was a stable branch (2.4) where only relatively minor and safe changes were merged, and an unstable branch (2.5), where bigger changes and cleanups were allowed. Both of these branches had been maintained by the same set of people, led by Torvalds. This meant that users would always have a well-tested 2.4 version with the latest security and bug fixes to use, though they would have to wait for the features which went into the 2.5 branch.

On est un peu loin du Mac et d'Apple dans cette brève, mais les conséquences risquent d'avoir un impact direct sur son écosystème… Et en plus c'est très intéressant :) Android, le système d'exploitation pour mobiles et tablettes de Google a déjà plusieurs procédures judiciaires en cours.

Avec Android, Google aurait "privatisé" une partie du noyau Linux

Celle dont on a le plus entendu parler est sans doutes l'attaque d'Oracle qui reproche à Google d'avoir volé du code de Java.Il ya quelques jours, il a été découvert que Google utilisait des scripts maison pour "nettoyer" les commentaires et d'autres informations de plus de 700 fichiers de code source du noyau Linux (2,5 Mo exactement). À la suite de quoi, en haut de chaque fichier la mention "no copyrightable information" était ajoutée.Sans entrer dans les détails des différentes licences que Google utilise pour Android, il faut comprendre de cette affaire qu'ils auraient en fait détourné l'esprit de la licence GPLv2, celle qui gouverne à l'utilisation du noyau Linux.
