Anatomy of Security-Enhanced Linux

Linux® has been described as one of the most secure operating systems available, but the National Security Agency (NSA) has taken Linux to the next level with the introduction of Security-Enhanced Linux (SELinux). SELinux takes the existing GNU/Linux operating system and extends it with kernel and user-space modifications to make it bullet-proof. If you're running a 2.6 kernel today, you might be surprised to know that you're using SELinux right now! This article explores the ideas behind SELinux and how it's implemented.

Windows-Linux Integration

"The use of Linux is no longer the sole preserve of IT administrators and tech-savvy computer users. Linux can now easily be incorporated into your environment without even having to go through the hassle of re-partitioning a disk. My previous article on VMWare illustrates that Linux is now pretty much a tool for everyone to use. However, one argument often made against the use of Linux is the difficulty of managing it. For instance, can you easily store and retrieve files on a Linux machine? Also, what about the problem of just interacting with and running the Linux machine? Isn't keeping up to date with Linux security patches a big problem? These are all good questions that I answer in the remainder of this article.

Kernel Devs Publish Position Statement on Linux Kernel Modules

We, the undersigned Linux kernel developers, consider any closed-source Linux kernel module or driver to be harmful and undesirable. We have repeatedly found them to be detrimental to Linux users, businesses, and the greater Linux ecosystem. Such modules negate the openness, stability, flexibility, and maintainability of the Linux development model and shut their users off from the expertise of the Linux community. Vendors that provide closed-source kernel modules force their customers to give up key Linux advantages or choose new vendors. Therefore, in order to take full advantage of the cost savings and shared support benefits open source has to offer, we urge vendors to adopt a policy of supporting their customers on Linux with open-source kernel code.

Avnet Launches MicroBlaze Processor Linux Design Solution

Avnet Inc. has released its Xilinx MicroBlaze Processor Linux DVD, MicroBlaze Processor Linux Starter Kit and the launch of the Linux for MicroBlaze Processor SpeedWay Design Workshop. The stand-alone Linux for MicroBlaze Processor DVD is based on both PetaLogix Petalinux and LynuxWork’s BlueCAT Linux distribution and tool chains. The DVD demonstrates how to port Linux into a Field Programmable Gate Array (FPGA) design using the 32-bit Xilinx MicroBlaze processor. It also highlights the benefits and tradeoffs when using the Memory Management Unit (MMU) in the MicroBlaze processor. The MMU enables designers to use commercial-grade operating systems when implementing their embedded designs with Xilinx FPGAs. The MicroBlaze Processor Linux Starter Kit includes the Linux for MicroBlaze Processor DVD, the Xilinx Embedded Development Kit - Spar

HP makes another contribution to Linux community

Continuing its efforts to advance customer adoption of Linux, HP has announced the contribution of its Tru64 UNIX Advanced File System (AdvFS) source code to the open source community. The AdvFS source code includes capabilities that increase uptime, enhance security and help ensure maximum performance of Linux file systems. HP will contribute the code as a reference implementation of an enterprise Linux file system under the terms of General Public License Version 2 for compatibility with the Linux kernel, as well as provide design documentation, test suites and engineering resources. The source code serves as a rich technology base to advance ongoing development of Linux by providing a comprehensive foundation for Linux kernel developers to leverage and improve Linux file system functionality.

AMD's New Card Supports Linux From the Get-Go

Michael writes "Back in September AMD had announced a new ATI Linux driver as well as opening up their GPU specifications, and today they have taken an additional step to better support the Linux OS. With the just-announced Radeon HD 4850 RV770 they have provided same-day Linux support, and the Linux driver is now shipping alongside the Windows driver on their product CDs. In addition, they are encouraging their AIB partners to showcase Tux on the product packaging as a sign of Linux support. Last but certainly not least, AMD is committed from top-to-bottom product support on Linux and they will be introducing high-end features in their Linux driver such as MultiGPU CrossFire technology. Phoronix has a run-down on AMD's evolutionary leap in Linux support along with information on the open-source support for the RV770 GPU.

Linux experiences 'prolific' growth, says Linux Foundation's Zemlin

The Linux Foundation is now a year old. Formed by the 2007 merger of Open Source Development Labs and the Free Standards Group and home to Linux's creator Linus Torvalds, the Foundation promotes the use of Linux through support for kernel development; the development of common definitions, standards and best practices; and resolution of legal issues. At Red Hat Summit, SearchEnterpriseLinux.com got a chance to speak with Jim Zemlin, the executive director of the Linux Foundation, in Boston and got the latest on all things Linux. Here's what he had to say.
