    Upgrading CFEngine Nova A CFEngine Special Topics Handbook CFEngine AS This document describes how software updates work in CFEngine Nova. ¨ © Copyright c 2010- CFEngine AS 1 v i Table of Contents What does upgrading mean? ::::::::::::::::::::::::::::::::::::::::: 3 Why do I need to upgrade?::::::::::::::::::::::::::::::::::::::::::: 3 How does upgrading work? ::::::::::::::::::::::::::::::::::::::::::: 3 How can I do phased deployment? :::::::::::::::::::::::::::::::::::: 4 What if I have multiple operating system platforms? ::::::::::::::::::: 4 How do Nova policies update if I already have my own policy? ::::::::: 4 Appendix A Manual package upgrade commands ::::::: 5 3 What does upgrading mean? A software upgrade involves obtaining a new version of the CFEngine software from soft- ware.CFEngine.com and installing it in place of the old. When software is updated, the previous version of the software is retained. From version 1.1 of CFEngine Nova, CFEngine is fully capable of managing its own updates ¨ and service restarts with a minimum of manual work on the policy server. Existing users of version 1.0 will need to upgrade the software manually on the affected sys- tems, or use the existing CFEngine to assist in the manual process. Please contact CFEngine Professional Services for for assistance (see Appendix). © Why do I need to upgrade? Bug fixes and new features are included in new software releases. To gain access to these fixes, you need to upgrade the software. Changes to the standard Community Open Promise Body Library might make use of new features, so upgrading brings you access to these new methods. How does upgrading work? CFEngine packages its software in operating sytsem compatible package formats (RPM, PKG, MSI, etc).

Security kernels, such as separation kernels, enable constructing high-assurance mixed-criticality execution platforms. They reduce the soft- ware portion of the system’s trusted computing base to a thin layer, which enforces isolation between low- and high-criticality components. The reduced trusted computing base minimizes the system attack surface and facilitates the use of formal methods to ensure functional correctness and security of the kernel. In this thesis, we explore various aspects of building a provably secure separation kernel using virtualization technology. In particular, we examine techniques related to the appropriate management of the memory subsystem. Once these techniques were implemented and functionally verified, they pro- vide reliable a foundation for application scenarios that require strong guar- antees of isolation and facilitate formal reasoning about the system’s overall security. We show how the memory management subsystem can be virtualized to enforce isolation of system components.

    A Real Time Operating Systems (RTOS) Comparison Rafael V. Aroca1, Glauco Caurin1 1Laboratorio´ de Mecatronicaˆ Escola de Engenharia de Sao˜ Carlos (EESC) – Universidade de Sao˜ Paulo (USP) Av. Trabalhador Sao-Carlense,˜ 400 – CEP 13566-590 – Caixa Postal 359 Sao˜ Carlos – SP – Brasil [email protected], [email protected] Abstract. This article presents quantitative and qualitative results obtained from the analysis of real time operating systems (RTOS). The studied systems were Windows CE, QNX Neutrino, VxWorks, Linux and RTAI-Linux, which are largely used in industrial and academic environments. Windows XP was also analysed, as a reference for conventional non-real-time operating system, since such systems are also commonly and inadvertently used for instrumentation and control purposes. The evaluations include worst case response times for latency, latency jitter and response time. Resumo. Este artigo demonstra resultados de uma analise´ quantitativa e qual- itativa realizada em sistemas operacionais de tempo real (RTOS). Os sistemas estudados foram Windows CE, QNX Neutrino, VxWorks, Linux e RTAI-Linux, que sao˜ bastante utilizados em ambientes academicosˆ e industriais. O Windows XP tambem´ foi analisado, como uma referenciaˆ de sistemas operacionais con- vencionais que nao˜ sao˜ de tempo real, ja´ que estes tipos de sistema sao˜ usados comum e inadvertidamente para propositos´ de instrumentac¸ao˜ e controle.

Introduction Real Time Operating Systems (RTOS) are specially designed to meet rigorous time con- straints. In several situations RTOS are present in embedded systems, and most of the time they are not noticed by the users.

These improvements contribute to program quality via Xen TCP/IP and have allowed application programmers to write increasingly gdb complicated programs.
