Linux Advanced Routing Traffic Control Bert Hubert PowerDNS. COM, bv bert@ powerdns. com, http://ds9a. nl/ Abstract Linux contains a wildly powerful system for shaping traffic and distributing it according to elaborate rules. This paper serves a dual pur- pose: to explain
Linux security module framework
free download
Computer security is a chronic and growing problem, even for Linux , as evidenced by the seemingly endless stream of software security vulnerabilities. Security research has produced numerous access control mechanisms that help improve system security;
Linux in a Brave New Firmware Environment
free download
Initially included exclusively on Intel 1 Itanium 2 platforms, the Extensible Firmware Interface Architecture (EFI) will soon be supported on IA-32 server, workstation, and desktop systems. This paper provides insight into the design and composition of an EFI enabled IA
Live migration with pass-through device for Linux VM
free download
Open source Linux virtualization, such as Xen and KVM, has made great progress recently, and has been a hot topic in Linux world for years. With virtualization support, the hypervisor de-privileges operating systems as guest operating systems and shares physical resources
Cooperative linux
free download
In this paper Ill describe Cooperative Linux , a port of the Linux kernel that allows it to run as an unprivileged lightweight virtual machine in kernel mode, on top of another OS kernel. It allows Linux to run under any operating system that supports loading drivers, such as
Pktgen the linux packet generator
free download
Abstract pktgen is a high-performance testing tool included in the Linux kernel. pktgen is currently the best tool to test the TX process of device driver and NIC. pktgen can also be used to generate ordinary packets to test other network devices. Especially of interest is the
Linux 2.6 performance improvement through readahead optimization
free download
Readahead design is one of the crucial aspects of filesystem performance. In this paper, we analyze and identify the bottlenecks in the redesigned Linux 2.6 readahead code. Through various benchmarks we identify that 2.6 readahead design handles database workloads
Kdump: Smarter, easier, trustier
free download
Kdump, a kexec based kernel crash dumping mechanism, has witnessed a lot of new significant development activities recently. Features like, the relocatable kernel, dump filtering, and initrd based dumping have enhanced kdump capabilities are important steps
Linux on NUMA systems
free download
NUMA is becoming more widespread in the marketplace, used on many systems, small or large, particularly with the advent of AMD Opteron systems. This paper will cover a summary of the current state of NUMA, and future developments, encompassing the VM subsystem
Demands, solutions, and improvements for Linux filesystem security
free download
Securing file resources under Linux is a team effort. No one library, application, or kernel feature can stand alone in providing robust security. Current Linux access control mechanisms work in concert to provide a certain level of security, but they depend upon the
Virtualization of Linux servers
free download
Virtualization of x86 servers has been a hot topic in the last decade, culminating in changes in the architectures design and the development of new technologies based in different approaches to provide server virtualization. In this paper, we present a comparative study of

eCryptfs: An enterprise-class encrypted filesystem for linux
free download
Abstract eCryptfs is a cryptographic filesystem for Linux that stacks on top of existing filesystems. It provides functionality similar to that of GnuPG, except the process of encrypting and decrypting the data is done transparently from the perspective of the
Linux kernel hotplug CPU support
free download
Abstract During the 2.5 development series, many people collaborated on the infrastructure to add (easy) and remove (hard) CPUs under Linux . This paper will cover the approaches we used, tracing back to the initial PowerPC hack with Anton Blanchard in February 2001
LTTng: Tracing across execution layers, from the hypervisor to user-space
free download
This presentation discusses the upcoming changes to be proposed to the kernel tracing field by the LTTng community. It will start by explaining what has been mainlined (per-cpu atomic operations, Linux Kernel Markers.) Then, the focus will turn to the patch set currently
Energy-aware task and interrupt management in linux
free download
As multi-core and SMP systems become more generally available, energy management needs in LinuxTM have also become more complex. Energy management in Linux was primarily designed for interactive systems where relatively simple inactivity based strategies

Improving linux startup time using software resume (and other techniques)
free download
This paper presents a new resume operation as well as other startup time improvement techniques which are aimed at achieving fast startup time for embedded Linux systems. A new fast boot method called snapshot boot is introduced. Snapshot boot is essentially a
Improving Linux resource control using CKRM
free download
One of the next challenges faced in Linux kernel development is providing support for workload management. Workloads with diverse and dynamically changing resource demands are being consolidated on larger symmetric multiprocessors. At the same time, it is
