Compiling the Linux Kernel

IconAt the time I was writing this article, the Linux kernel 2.4.17 was released only 3 days ago and these holly days you may find some more time to experiement with it. The following article includes step-by-step instructions on how to compile a Linux 2.4.X kernel, an article mostly targetting people who have never dared to compile their own kernel yet. Read on and we promise, it is not that hard to do so.

Book Review: Linux Kernel Development

IconThe Linux phenomenon gets bigger by the day and more developers are drawn into developing for it. The heart of this very phenonmenon is its kernel and as time goes by it becomes more mature but also bigger and more complex. New developers would have trouble diving in and code for it, hence the "Linux Kernel Development" book by well known kernel hacker Robert Love (of preemptive-patch fame).

New Approach To Malware Modifies Linux Kernel

Hugh Pickens writes "Professor Avishai Wool has unveiled a program to watch for malware on servers with a modification to the Linux kernel. 'We modified the kernel in the system's operating system so that it monitors and tracks the behavior of the programs installed on it,' says Wool. Essentially, Wool says, his software team has built a model that predicts how software running on a server should work (pdf). If the kernel senses abnormal activity, it stops the program from working before malicious actions occur. 'When we see a deviation, we know for sure there's something bad going on,' Wool explains. Wool cites problems with costly anti-virus protection. 'Our methods are much more efficient and don't chew up the computer's resources.'"

ACM OSR Linux Issue Available For Free Download

Eric Van Hensbergen writes "In accordance with the ideals of the issue's open source topic, the ACM has agreed to make the July issue of Operating Systems Review: Research and Developments in the Linux Kernel available for download free of charge. It contains a number of interesting papers written by LKML members like Rusty Russell, Paul McKenna, and Eric Biederman as well as academic OS researchers who've made contributions to mainline on topics ranging from RCL, VirtIO, Checkpoint & Resume, to CUBIC TCP, etc. A primary motivation behind this special-topics OSR issue was to help bridge a gap that currently exists between the kernel community and the academic OS research community, by encouraging kernel developers to publish recent additions to the Linux kernel as well as to provide a forum for experience papers which describe the introdu

Real-time Linux in real time

The increasing market demand for systems characterized by low-latency, deterministic behavior and the emphasis on the use of commodity hardware and software have led to a new breed of real-time operating systems (OSs), known as enterprise real-time OSs. In response to the demand for accelerated access to such features in a Linux™ kernel, the IBM Linux and Java™ Technology Centers collaborated to provide the first commercially available enterprise real-time Linux kernel with real-time Java support. Extending the PREEMPT RT patch from Ingo Molnar of Red Hat, Inc., the kernel contains additional features that were required to meet the demands of enterprise real-time OS customers. This paper describes how IBM developers helped to direct, implement, and test the real-time Linux kernel, bringing it from software patches to a finished produc

Linux kernel developer's guide published

A guide to the kernel development process aims to encourage participation by new programmers by explaining what is involved. Some developers and businesses attempting to submit changes to the Linux kernel find themselves tangled up with the processes used, according to the guide, which was written by Jonathan Corbet, executive editor of lwn.net and himself a Linux developer.

Linux kernel updated for solid state

The Linux development community has released version 2.6.27 of the Linux kernel. This will be the first version of the kernel that includes a new file system designed for solid-state

New kernel boosts embedded

Updated 1:45 PM] -- Linus Benedict Torvalds today blessed the 2.6.27 kernel, making the release official after nine "release candidate" iterations. For embedded hackers, the new kernel offers "Ftrace" and "Sysprof" trace tools, a new "UBIFS" flash filesystem, and support for network drivers with multiple transmit queues, among other enhancements.

e1000e Bug Squashed — Linux Kernel Patch Released

ruphus13 writes "As mentioned earlier, there was a kernel bug in the alpha/beta version of the Linux kernel (up to 2.6.27 rc7), which was corrupting (and rendering useless) the EEPROM/NVM of adapters. Thankfully, a patch is now out that prevents writing to the EEPROM once the driver is loaded, and this follows a patch released by Intel earlier in the week. From the article: 'The Intel team is currently working on narrowing down the details of how and why these chipsets were affected. They also plan on releasing patches shortly to restore the EEPROM on any adapters that have been affected, via saved images using ethtool -e or from identical systems.' This is good news as we move towards a production release!"

Guide to Linux kernel development published

The Linux Foundation (LF) has published a guide by Jonathan Corbet (pictured) on how to participate in the Linux kernel development community. The 30-page guide explains the development process, but does not require a deep knowledge of kernel programming, says the non-profit group.

Linux Foundation Paving Way for New Kernel Developers

Jack Spine writes "The Linux Foundation has published a how-to document for developers who want to negotiate the hidden shoals of open source. According to both the Linux Foundation and the Open Source Consortium, developers can get frustrated with the processes in open source coding, especially for enterprise-class projects like Linux. 'A guide to the kernel development process' aims to encourage participation from new programmers by explaining what's involved. Some developers and businesses attempting to submit changes to the Linux kernel find themselves tangled up with the processes used, according to the guide, which was written by Jonathan Corbet, executive editor of lwn.net and himself a Linux developer."

Major Corruption Bug in e1000e Driver in Linux Kernel 2.6.27

IconI'm generally not very fond of reporting on security breaches or bugs, but OSNews reader and Mandriva employee Adam Williamson warned us of a pretty serious bug in pre-releases of the Linux kernel. "A major bug has been found in the e1000e module (which supports some Intel onboard ethernet adapters) in Linux kernel 2.6.27 pre-releases (up to and including 2.6.27rc7). It can cause the EEPROM of the adapter to become corrupted, rendering it non-functional. This may affect current pre-releases of distributions. Mandriva has posted a detailed notification about the issue, as has SUSE." So, watch out.

Red Hat acquires Qumranet

Qumranet is the inventor and key maintainer of KVM, the only virtualization technology that is fully incorporated into the Linux kernel. Red Hat views KVM as the next generation of virtualization technology -- it combines support for the latest hardware virtualization capabilities and the rapid feature development of the Linux kernel into a complete, highly functional, virtualization platform. Red Hat believes that a strong coupling between the hypervisor and the kernel is a major advantage.

Kernel space: Virus scanning API spawns security debate

The TALPA malware scanning API was covered in LWN in December, 2007. Several months later, TALPA is back - in the form of a patch set posted by a Red Hat employee. The resulting discussion has certainly not been what the TALPA developers would have hoped for; it is, instead, a good example of how a potentially useful idea can be set back by poor execution and presentation to the kernel community.

Arjan and other hackers have already improved the Linux user experience by reducing power consumption and latency. O'Reilly News interviewed him about his work on improving the Linux experience with PowerTOP, LatencyTOP, and Five-Second Boot."
