  UNIX is the best operating system ever designed so everybody is running UNIX on their computer, right ? This presentation takes a partisan looks a why UNIX never became a big success in the eighties, failed to win the market in the nineties, and still struggles in the market in the new millenium. Poul-Henning will take a critical look at the mistakes of the past and the mistakes of the present and try to make it really clear what needs to happen for UNIX to become a real success.

  How the FreeBSD Project Works (EuroBSDCon 2006 Full Conference) (4.4 Mb), TrustedBSD presentation on Audit and priv(9) (Developer Summit) (166 Kb)
  EuroBSDCon 2006 took place in Milan, Italy, and not only offered excellent food on a flexible schedule, but also an interesting array of talks on work spanning the BSD's. On this page, you can find my slides from the FreeBSD developer summit and full conference.
  Status report on the TrustedBSD Project: introduction and status regarding Audit, plus a TODO list; introduction to the priv(9) work recently merged to 7.x.
  The FreeBSD Project is one of the oldest and most successful open source operating system projects, seeing wide deployment across the IT industry. From the root name servers, to top tier ISPs, to core router operating systems, to firewalls, to embedded appliances, you can't use a networked computer for ten minutes without using FreeBSD dozens of times. Part of FreeBSD's reputation for quality and reliability comes from the nature of its development organization--driven by a hundreds of highly skilled volunteers, from high school students to university professors. And unlike most open source projects, the FreeBSD Project has developers who have been working on the same source base for over twenty years. But how does this organization work? Who pays the bandwidth bills, runs the web servers, writes the documentation, writes the code, and calls the shots? And how can developers in a dozen time zones reach agreement on the time of day, let alone a kernel architecture? This presentation will attempt to provide, in 45 minutes, a brief if entertaining snapshot into what makes FreeBSD run.

  Introduction to Multithreading and Multiprocessing in the FreeBSD SMPng Network Stack (370 Kb)
  EuroBSDCon 2005 took place in Basel, Switzerland in November, 2005. Due to an injury, I was unable to attend the conference itself, and my talks were presented in absentia by Poul-Henning Kamp and Ed Maste, who have my greatest appreciation!
  The FreeBSD SMPng Project has spent the past five years redesigning and reimplementing SMP support for the FreeBSD operating system, moving from a Giant-locked kernel to a fine-grained locking implementation with greater kernel threading and parallelism. This paper introduces the FreeBSD SMPng Project, its architectural goals and implementation approach. It then explores the impact of SMPng on the FreeBSD network stack, including strategies for integrating SMP support into the network stack, locking approaches, optimizations, and challenges.

Association for Computing Machinery. , Diomidis Spinellis. A tale of four kernels. In Wilhem Schfer, Matthew B. Dwyer, and Volker Gruhn, editors, ICSE '08: Proceedings of the 30th International Conference on Software Engineering, pages 381-390, New York, May 2008. Association for Computing Machinery.
  The FreeBSD, GNU/Linux, Solaris, and Windows operating systems have kernels that provide comparable facilities. Interestingly, their code bases share almost no common parts, while their development processes vary dramatically. We analyze the source code of the four systems by collecting metrics in the areas of file organization, code structure, code style, the use of the C preprocessor, and data organization. The aggregate results indicate that across various areas and many different metrics, four systems developed using wildly different processes score comparably. This allows us to posit that the structure and internal quality attributes of a working, non-trivial software artifact will represent first and foremost the engineering requirements of its construction, with the influence of process being marginal, if any.

  "User Interfaces and How People Think" will introduce concepts of designing software for different users by observing how they think about and do what they do. While much of design today focuses on the front-end of computer systems, there is opportunity to innovate in every area where a human interacts with software.

  SSARES: Secure Searchable Automated Remote Email Storage - A usable, secure email system on a remote untrusted server

  The increasing centralization of networked services places user data at considerable risk. For example, many users store email on remote servers rather than on their local disk. Doing so allows users to gain the benefit of regular backups and remote access, but it also places a great deal of unwarranted trust in the server. Since most email is stored in plaintext, a compromise of the server implies the loss of confidentiality and integrity of the email stored therein. Although users could employ an end-to-end encryption scheme (e.g., PGP), such measures are not widely adopted, require action on the sender side, only provide partial protection (the email headers remain in the clear), and prevent the users from performing some common operations, such as server-side search.

  To address this problem, we present Secure Searchable Automated Remote Email Storage (SSARES), a novel system that offers a practical approach to both securing remotely stored email and allowing privacy-preserving search of that email collection. Our solution encrypts email (the headers, body, and attachments) as it arrives on the server using public-key encryption. SSARES uses a combination of Identity Based Encryption and Bloom Filters to create a searchable index. This index reveals little information about search keywords and queries, even against adversaries that compromise the server. SSARES remains largely transparent to both the sender and recipient. However, the system also incurs significant costs, primarily in terms of expanded storage requirements. We view our work as a starting point toward creating privacy-friendly hosted services.

  pfSense Tutorial

  From Zero to Hero with pfSense

  pfSense is a free, open source customized distribution of FreeBSD tailored for use as a firewall and router. In addition to being a powerful, flexible firewalling and routing platform, it includes a long list of related features and a package system allowing further expandability without adding bloat and potential security vulnerabilities to the base distribution. pfSense is a popular project with more than 1 million downloads since its inception, and proven in countless installations ranging from small home networks protecting a PC and an Xbox to large corporations, universities and other organizations protecting thousands of network devices.

  This tutorial is being presented by the founders of the pfSense project, Chris Buechler and Scott Ullrich.

  The session will start with an introduction to the project, hardware sizing and selection, installation, firewalling concepts and basic configuration, and continue to cover all the most popular features of the system. Common usage scenarios, deployment considerations, step by step configuration guidance, and best practices will be covered for each feature. Most configurations will be demonstrated in a live lab environment.

  Attendees are assumed to have basic knowledge of TCP/IP and firewalling concepts, however no in-depth knowledge in these areas or prior knowledge of pfSense or FreeBSD is necessary.

  Bacula

  The Open Source Enterprise Backup Solution

  The Bacula project started in January 2000 with several goals, one of which was the ability to backup any client from a Palm to a mainframe computer. Bacula is available under a GPL license.

  Bacula uses several distinct components, each communicating via TCP/IP, to achieve a very scalable and robust solution to backups.

  Kern is one of the original project founders and still one of the most productive Bacula developers.

  FreeBSD/mips

  Embedding FreeBSD

  FreeBSD now runs on the MIPS platform. FreeBSD/mips supports MIPS-32 and MIPS-64 targets, including SMP for multicore support.

  FreeBSD/mips is targeted at the embedded MIPS marketplace. FreeBSD has run on the MIPS platform for many years. Juniper ported FreeBSD to the Mips platform in the late 1990's. However, concern about intellectual property issues kept Juniper from contributing the port back to FreeBSD until recently. The contributed port was a 64-bit mips port.

  In the mean time, many efforts were made to bring FreeBSD to the mips platform. The first substantial effort to bring FreeBSD to the Mips platform was done by Juli Mallet. This effort made it to single user, but never further than that. This effort was abandoned due to a change in Juli's life. The port languished.

  Two years ago at BSDcan, as my involvement with FreeBSD/arm was growing, I tried to rally the troops into doing a FreeBSD/mips port. My efforts resulted in what has been commonly called the "mips2" effort. The name comes from the choice of //depot/projects/mips2 to host the work in perforce. A number of people worked on the earliest versions of the port, but it too languished and seemed destined to suffer the same fate as earlier efforts. Then, two individuals stood up and started working on the port. Wojciech A. Koszek and Oleksandr Tymoshenko pulled in code from the prior efforts. Through their efforts of stabilizing this code, the port to the single user stage and ported it to three different platforms. Others ported it to a few more. Snapshots of this work were released from time to time.

  Cavium Networks picked up one of these snapshots and ported it to their multicore mips64 network processor. Cavium has kindly donated much of their work to the comminuty.

  In December, I started at Cisco systems. My first job was to merge all the divergent variants of FreeBSD/mips and get it into shape to push into the tree. With luck, this should be in the tree before I give my talk.

  In parallel to this, other advances in the embedded support for FreeBSD have been happening as well. I'll talk about new device drivers, new subsystems, and new build tools that help to support the embedded developer.

  Building self-contained PBIs from Ports (Automagically)

  Creating a self-contained application from the ports tree

  PC-BSD provides a user-friendly desktop experience, for experts and casual users alike. PC-BSD is 100% FreeBSD under the hood, while providing desktop essentials, such as a graphical installation system, point-n-click package-management using the PBI system, and easy to use system management tools; All integrated into an easy to use K Desktop Environment (KDE).

  The PBI (Push Button Installer) format is the cornerstone of the PC-BSD desktop, which allows users to install applications in a self-contained format, free from dependency problems, and compile issues that stop most casual users from desktop adoption. The PBI format also provides power and flexibility in user interaction, and scripting support, which allows applications to be fine-tuned to the best possible user experience.

  This talk would go over in some detail our new PBI building system, which converts a FreeBSD port, such as FireFox, into a standalone self-contained PBI installer for PC-BSD desktops.

  The presentation will be divided into two main sections:
  The Push Button Installer (PBI) Format

  • The basics of the PBI format
  • The PBI format construction
  • Add & Remove scripting support within PBI

  Building PBIs from Ports "Auto-magically"

  • The PBI build server & standalone software
  • Module creation & configuration
  • Converting messy ports into PBIs

  An Open Source Enterprise VPN Solution with OpenVPN and OpenBSD

  Solving the problem

  At Appalachian State University, we utilize an open source VPN to allow faculty, staff and vendors secure access to Appalachian State University's internal network from any location that has an Internet connection. To implement our virtual private network project, we needed a secure VPN that is flexible enough to work with our existing network registration and LDAP authentication systems, has simple client installation, is redundant, allows multiple VPN server instances for special site-to-site tunnels and unique configurations, and can run on multiple platforms. Using OpenVPN running on OpenBSD, we met those requirements and added a distributed administration system that allows select users to allow VPN access to specific computers for external users and vendors without requiring intervention from our network or security personnel. Our presentation will start with a quick overview of OpenVPN and OpenBSD and then detail the specifics of our VPN implementation.

  Dissatisfied with IPSec for road warrior VPN usage we went looking for a better solution. We had hopped that we could find a solution that would run on multiple platforms, was flexible and worked well. We found OpenVPN and have been pleased. Initially we ran it on RHEL. We migrated to OpenBSD for pf functionality and general security concerns. ...and because we like OpenBSD.

  Our presentation will focus on the specifics of our VPN implementation. We will quickly cover the basics of OpenVPN and the most used features of OpenBSD. Moving along we will cover multiple authentication methods, redundancy, running multiple instances, integration with our netreg system, how pf has extended functionality, embedding in appliances, and client configuration. The system has proven helpful with providing vendor access where needed and we'll cover this aspect as well. Time permitting we will cover current enhancement efforts and future plans.

  OpenVPN has been called the "Swiss army knife" of VPN solutions. We hope our presentation leaves participants with that feeling.

  "finstall" - the new FreeBSD installer

  A graphical installer for FreeBSD

  The "finstall" project, sponsored by Google as a Summer of Code 2007 project, is an attempt to create a user-friendly graphical installer for FreeBSD, with enough strong technical features to appeal to the more professional users. A long term goal for it is to be a replacement for sysinstall, and as such should support almost all of the features present in sysinstall, as well as add support for new FreeBSD features such as GEOM, ZFS, etc. This talk will describe the architecture of "finstall" and focus on its lesser known features such as remote installation.

  "finstall" is funded by Google SoC as a possible long-term replacement for sysinstall, as a "LiveCD" with the whole FreeBSD base system on the CD, with X11 and XFCE4 GUI. In the talk I intend to describe what I did so far, and what are the future plans for it. This includes the installer GUI, the backend (which has the potential to become a generic FreeBSD configuration backend) and the assorted tools developed for finstall ("LiveCD" creation scripts). More information on finstall can be found here: http://wiki.freebsd.org/finstall.

  Measured (almost) does Air Traffic Control

  Monitoring weird hardware reliably

  The new Danish Air Traffic Control system, CASIMO, prompted the development on a modular and general software platform for data collection, control and monitoring of "weird hardware" of all sorts.

  The talk will present the "measured" daemon, and detail some of the uses it has been put to, as an, admittedly peripheral, component of the ATC system.

  Many "SCADA" systems suffer from lack of usable interfaces for external access to the data. Measured takes the opposite point of view and makes real-time situation available, and accepts control instructions as ASCII text stream over TCP connections. Several examples of how this can be used will be demonstrated.

  Measured will run on any FreeBSD system, but has not been ported to other UNIX variants yet, and it is perfect for that "intelligent house" project of yours.

  I believe I gave a WIP presentation of this about two years ago.

  BSD licensed C++ compiler

  LLVM is a suite of carefully designed open source libraries that implement compiler components (like language front-ends, code generators, aggressive optimizers, Just-In-Time compiler support, debug support, link-time optimization, etc.). The goal of the LLVM project is to build these components in a way that allows them to be combined together to create familiar tools (like a C compiler), interesting new tools (like an OpenGL JIT compiler), and many other things we haven't thought of yet. Because LLVM is under continuous development, clients of these components naturally benefit from improvements in the libraries.

  This talk gives an overview of LLVM's design and approach to compiler construction, and gives several example applications. It describes applications of LLVM technology to llvm-gcc (a C/C++/Objective C compiler based on the GNU GCC front-end), the OpenGL stack in Mac OS/X Leopard, and Clang. Among other things, the Clang+LLVM Compiler provides a fully BSD-Licensed C and Objective-C compiler (with C++ in development) which compiles code several times faster than GCC, produces code that is faster than GCC in many cases, produces better warnings and error messages, and supports many other applications (e.g. static analysis and refactoring).

  Summer of Code

  In this talk, I will briefly discuss some general ways Google's Open Source Team contributes to the wider community. The rest of the talk will explore some highlights of the Google Summer of Code program, our initiative to get university students involved in Open Source development.

  I will cover the program's inception, lessons learned over time and tips for success in the program for both mentors and students. In particular, the talk will detail some experiences of the *BSD mentoring organizations involved in the program as a case study in successfully managing the program from the Open Source project's perspective. Any Google Summer of Code participants in the audience are welcome and encouraged to chime in with their own insights.

  A closer look at the ZFS file system

  simple administration, transactional semantics, end-to-end data integrity

  SUN's ZFS file system became part of FreeBSD on 6th April 2007. ZFS is a new kind of file system that provides simple administration, transactional semantics, end-to-end data integrity, and immense scalability. ZFS is not an incremental improvement to existing technology; it is a fundamentally new approach to data management. We've blown away 20 years of obsolete assumptions, eliminated complexity at the source, and created a storage system that's actually a pleasure to use.

  ZFS presents a pooled storage model that completely eliminates the concept of volumes and the associated problems of partitions, provisioning, wasted bandwidth and stranded storage. Thousands of file systems can draw from a common storage pool, each one consuming only as much space as it actually needs. The combined I/O bandwidth of all devices in the pool is available to all filesystems at all times.

  All operations are copy-on-write transactions, so the on-disk state is always valid. There is no need to fsck(1M) a ZFS file system, ever. Every block is checksummed to prevent silent data corruption, and the data is self-healing in replicated (mirrored or RAID) configurations. If one copy is damaged, ZFS detects it and uses another copy to repair it.

  Interfacing embedded FreeBSD with U-Boot

  Working with the de facto standard for an initial level boot loader

  In the embedded world U-Boot is a de facto standard for an initial level boot loader (firmware). It runs on a great number of platforms and architectures, and is open source.

  This talk covers the development work on integrating FreeBSD with U-Boot-based systems. Starting with an overview of differences between booting an all-purpose desktop computer vs. embedded system, FreeBSD booting concepts are explained along with requirements for the underlying firmware.

  Historical attempts to interface FreeBSD with this firmware are mentioned and explanation given on why they failed or proved incomplete. Finally, the recently developed approach to integrate FreeBSD and U-Boot is presented, with implementation details and particular attention on how it's been made architecture and platform independent, and how loader(8) has been bound to it.

  Introduction to Debugging the FreeBSD Kernel

  Just like every other piece of software, the FreeBSD kernel has bugs. Debugging a kernel is a bit different from debugging a userland program as there is nothing underneath the kernel to provide debugging facilities such as ptrace() or procfs. This paper will give a brief overview of some of the tools available for investigating bugs in the FreeBSD kernel. It will cover the in-kernel debugger DDB and the external debugger kgdb which is used to perform post-mortem analysis on kernel crash dumps.

  Introduction to Debugging the FreeBSD Kernel

  • Basic crash messages, what a crash looks like
    • typical panic() invocation
    • page fault example
  • "live" debugging with DDB
    • stack traces
    • ps
    • deadlock examples
    • show lockchain
    • show sleepchain
    • Adding new DDB commands
  • KGDB
    • inspecting processes and threads
    • working with kernel modules
    • using scripts to extend
  • examining crashdumps using utilities
    • ps, netstat, etc.
  • debugging strategies
    • kernel crashes
    • system hangs

  DTrace for FreeBSD

  What on earth is that system doing?!

  DTrace is a comprehensive dynamic tracing facility originally developed for Solaris that can be used by administrators and developers on live production systems to examine the behavior of both user programs and of the operating system itself. DTrace enables users to explore their system to understand how it works, track down performance problems across many layers of software, or locate the cause of aberrant behavior. DTrace lets users create their own custom programs to dynamically instrument the system and provide immediate, concise answers to arbitrary questions you can formulate using the DTrace D programming language.

  This talk discusses the port of the DTrace facility to FreeBSD and demonstrates examples on a live FreeBSD system.

  • Introduction to the D language - probes, predicates and actions.
  • dtrace(8) and libdtrace - the userland side of the DTrace story.
  • The DTrace kernel module, it's ioctl interface to userland and the provider infrastructure in the kernel.
  • DTrace kernel hooks and the problem of code licensed under Sun's CDDL.
  • What does a DTrace probe actually do?
  • DTrace safety and how it is implemented.
  • Build system changes to add CTF (Compact C Type Format) data to objects, shared libraries and executables.
  • The DTrace test suite.
  • A brief list of things to do to port the DTrace facility to other BSD-derived operating systems.

  What Not To Do When Writing Network Applications

  The lessons learnt working with not-so-high-performance network applications

  This talk will look at issues which face the modern network application developer, from the point of view of poorly-designed examples. This will cover internal code structure and dataflow, interaction with the TCP stack, IO scheduling in high and low latency environments and high-availability considerations. In essence, this presentation should be seen as a checklist of what not to do when writing network applications.

  Plenty of examples of well designed network applications exist in the open and closed source world today. Unfortunately there are just as many examples of fast network applications as there are "fast but workload specific"; sometimes failing miserably in handling the general case. This may be due to explicit design (eg Varnish) but many are simply due to the designer not fully appreciating the wide variance in "networks" - and their network application degrades ungracefully when under duress. My aim in this presentation is to touch on a wide number of issues which face network application programmers - most of which seem not "application related" to the newcomer - such as including pipelining into network communication, managing a balance between accepting new requests and servicing existing requests, or providing back-pressure to a L4 loadbalancer in case of traffic bursts. Various schemes for working with these issues will be presented, and hopefully participants will walk away with more of an understanding about how the network, application and operating systems interact.

  Using FreeBSD to Promote Open Source Development Methods

  In this talk we present Aerosource, an initiative to bring Open Source Software development methods to internal software developers at The Aerospace Corporation.

  Within Aerosource, FreeBSD is used in several key roles. First, we run most of our tools on top of FreeBSD. Second, the ports collection (both official ports and custom internal ones) eases our administrative burden. Third, the FreeBSD project serves as an example and role model for the results that can be achieved by an Open Source Software projects. We discuss the development infrastructure we have built for Aerosource based largely on BSD licensed software including FreeBSD, PostgreSQL, Apache, and Trac. We will also discuss our custom management tools including our system for managing our custom internal ports. Finally, we will cover our development successes and how we use projects like FreeBSD as exemplars of OSS development.

  Porting FreeBSD/ARM to Marvell Orion System-On-Chip

  This talk covers the development work on porting the FreeBSD/ARM to Marvell Orion family of highly integrated chips.

  ARM architecture is widely adopted in the embedded devices, and since the architecture can be licensed, many implementation variations exist: Orion is a derivative compliant with the ARMv5TE definition, it provides a rich set of on-chip peripherals.

  Present state of the FreeBSD support for ARM is explained, areas for improvement highlighted and its overall shape and condition presented.

  The main discussion covers scope of the Orion port (what integrated peripherals required new development, what was adapted from existing code base); design decisions are explained for the most critical items, and implementation details revealed.

  Summary notes are given on general porting methodology, debugging techniques and difficulties encountered during such undertaking.
