description: The verifiedexec feature has been part of NetBSD for some years now. It seems that a lot of people are unaware of the feature or do not know the full capabilities of verifiedexec. This talk will introduce the feature, what it can do and also what it could be capable of with some kernel changes. The verified execuction feature is a unique extension to the NetBSD kernel that allows an administrator to ensure the binaries and files that are being accessed have not been modified by comparing the fingerprint of the on-disk file with a "known good" copy of the fingerprint kept in kernel memory. This allows very fine grain control over what will be executed on the machine, even by root, and can provide assurance that files have not been modified. In this talk I will go over some of the history of verified execution, how it works and what it can do, then finally move on to what the next steps I want to take in the development of veriexec. Verified execution has been in NetBSD for a long time but it seems to be a feature that that is not widely known about, hopefully this talk can raise its profile somewhat.

description: The FreeBSD kernel uses seven different types of locks to ensure proper access to the resources that it manages. This talk describes the hierarchy of these locks from the low-level and simple to the high-level and full-featured. The functionality of each type of lock is described along with the problem domain for which it is intended. The talk concludes by describing the witness system within the FreeBSD kernel that tracks the usage of all the locks in the system and reports any possible deadlocks that might occur because of improper acquisition ordering of locks.

description: Security Event Audit is a facility to provide fine-grained, configurable logging of security-relevant events. Audit events are stored in trail files that can be used for postmortem analysis in case of system compromise. Once the system is compromised, an attacker has access to audit trail files and can modify or delete them. The auditdistd daemon's role is to distribute audit trail files to a remote system in a secure and reliable way. The talk will provide background to the Security Event Audit facility in FreeBSD and will describe auditdistd daemon in detail. The auditdistd daemon is a good example of using modern sandboxing mechanisms, like capsicum. During the talk audit subsystem and auditdistd daemon will be presented live.

description: Ever since the University of California, Berkeley CSRG implemented the chroot(8) command and system call in its BSD operating system in 1982, the community-developed BSD Unix derivatives have set the standard for the introduction of plurality to the conventionally-singular Unix computing model. Today's system operators and developers have an array of BSD-licensed multiplicity strategies at their disposal that offer various degrees of both isolation and virtualization when introducing plurality. This paper will survey current and experimental BSD multiplicity strategies including chroot, FreeBSD jail, NetBSD/Xen, Amazon EC2, compatlinux, GXemul and SIMH, plus experimental strategies such as FreeBSD BHyVe, compatmach, Usermode NetBSD, Dragonfly BSD vkernel, OpenBSD sysjail and NetBSD mult. As an applied survey, this paper will both categorize each multiplicity strategy by the Unix environment to which it introduces plurality and demonstrate the usage of the utilities relating to each solution. The survey criteria consist of five distinct Unix environments to which plurality is introduced: • Machine Multiplicity, as distinguished by the introduction of native and foreign hardware system and their distinct Instruction Set Architectures defined by distinct physical hardware systems, virtualized instances of them, or software emulattions of them (NetBSD-Xen/EC2, GXemul, SIMH and BHyVe) • Kernel Multiplicity, as distinguished by a plurality of executing kernels (Usermode NetBSD, Dragonfly BSD vkernel) • Init Multiplicity, as distinguished by distinct kernel-spawned init processes and their descendant processes (mult) • Userland Multiplicity, as distinguished by distinct userlands with optional process tables and their descendant processes (chroot, FreeBSD jail and sysjail) • API Multiplicity, as distinguished by distinct foreign Application Programming Interface compatibility layers (compatlinux, compatmach) The reader will thus come away with a set of working examples for each solution that they can implement on their own. In addition, this survey addresses key host and guest administrative considerations applicable to each multiplicity solution: • Storage Device considerations: Are they hardware or software-based? What image and file system formats are supported? • Network Device considerations: Are they configured by the host? From within the guest? • Console Device considerations: Does the guest appear on the host console? Is it redirected to a network-aware solution such as VNC or X11 over SSH? • Kernel considerations: Is the native or foreign guest kernel modified? Does it reside within or outside the guest userland? • Userland considerations: Is the guest userland modified? Does it lend itself to customization through additive or subtractive techniques?

description: When we needed dozens of storage, processing and front-end machines for a prototype of a new cloud media service, we developed a cost-effective, but technically challenging hybrid strategy of purchased, rented dedicated and rented virtual servers. FreeBSD was an easy choice thanks to its performance, reliability, and unparalleled ease of management on a per–node level. However, while the number of infrastructure–level tasks kept growing and we needed to scale through beta and release stages, there was an obvious need to reduce complexity. After a year of tentative design and experimenting with partial solutions, we started implementing in November 2011, the result-in-progress being something we call unified configuration management (and deployment), bringing immediate returns on time invested. The talk focuses on a new unified approach to deploying and managing modern versions of FreeBSD across a wide variety of technical and administrative circumstances: different countries, data centers, hardware, access policies, boot methods, networking, support contracts, machine roles, etc. While avoiding any popular Linux-centric CM systems, such as Puppet, Chef, and CFEngine, we achieve very low complexity by leveraging rc(8), loader(8), glabel(8) and other existing instruments, such as pkgng, to their potential as necessary. The cornerstone is keeping configuration and deployment versioned and unified — same across all cases, with no duplication of common parts and very simple specification of per-role/per-case peculiarities. The approach spans everything from installation and booting to managing third-party and custom site-specific software. The method is being actively developed and applied in production environment of a popular online music service.

NetBSD/mips

uk: Комп'ютерні науки

description: Since NetBSD 5 was released, the support for MIPS on NetBSD has been completely revamped. It is now one of the more advanced ports of NetBSD. This talk is an overview on what has changed and what the current state of MIPS support and a brief look forward to what else is coming. Subjects to be covered: Why? (Big Embedded space, large amounts of memory, etc). Quick Introduction to the MIPS architecture Overview of XLR/XLS/XLP Overview of what changed (toolchain, SMP, pmap, PCU, compat32, new cpu support, use of MIPS features, fast softint) Design decisions why N32 by default? why no separate mips64? Major features 64-bit address space cpu abstraction dynamic fixups (changing indirect calls to direct calls) splsw UVM changes Fast software interrupts SMP (for NetLogic XLR/XLS/XLP) mostly lockless pmap Choosing a new page size COMPAT_NETBSD32 networking filesystem mounting 32-bit systems N32 Kernels Effects on the NetBSD in general PCU direct-mapped UAREAs COMPAT_NETBSD32 common pmap for TLB based MMUs

pfSense 2.1: IPv6 and more

uk: Комп'ютерні науки

description: pfSense is a BSD licensed 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. This session is being presented by the founders of the pfSense project, Chris Buechler and Scott Ullrich. At the time of BSDCan 2012, pfSense 2.1 will be newly released. This release adds IPv6 support to nearly every portion of the system, as well as some other smaller changes. This session will cover all of the changes in the 2.1 release, primarily focusing on adding IPv6 support to your existing deployments. With IPv4 address space dwindling and World IPv6 Launch coming up in June, now is the time to bring up IPv6 on your networks. While IPv6 brings new benefits, it also poses new security and connectivity considerations, which will be covered. Attendees will come away with all the latest on the project, as well as knowledge to securely bring their networks onto the 21st century Internet with IPv6.

MINIX 3

uk: Комп'ютерні науки

description: Most computer users nowadays are nontechnical people who have a mental model of what they expect from a computer based on their experience with TV sets and stereos: you buy it, plug it in, and it works perfectly for the next 10 years. Computers aren't like that, which leads to frustration. Part of the problem is the operating system, which is often millions of lines of kernel code, each of which can potentially bring the system down. As long as we maintain the current structure of the operating system as a huge single monolithic program full of foreign code device drivers) and running in kernel mode, the situation will not improve. In an attempt to provide better reliability and security, we have created a new multiserver operating system, MINIX 3, with only 15,000 lines in kernel and the rest of the operating system split up into small components each running as a separate user-mode processes. It is available for the x86 and ARM for embedded systems. The talk will discuss the design of the system and some of unique aspects, such as live update--the ability to replace the operating system with a new version while it is running without affecting running applications.

Access Without Empowerment

uk: Комп'ютерні науки

description: The free software movement has twin goals: promoting access to software through users' freedom to share, and empowering users by giving them control over their technology. For all our movement's success, we have been much more successful at the former. I will use data from free software and from several related movements to explain why promoting empowerment is systematically more difficult than promoting access and I will explore how our movement might address the second challenge in the future.
