BSDCan-2012 - Michael Dexter - An applied survey of BSD multiplicity and virtualization strategies from chroot to BHyVe
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.

BSDCan-2012 - Kirk McKusick - An Overview of Locking in the FreeBSD Kernel
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.

BSDCan-2012 - Pawel Jakub Dawidek - auditdistd - Secure and reliable distribution of audit trail files
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.

BSDCan-2012 - Ivan Voras - Bullet Cache - Balancing speed and usability in a cache server
Bullet Cache is an in-memory cache server inspired by memcached, but with a twist: a powerful record tagging and bulk query facility, configurable multithreading models and a dump / cache prewarm option. This talk will have two parts: a technical description of Bullet Cache's implementation with focus on programming techniques and optimizations, and a description of usage scenarios with the focus on how it can help real-world applications (not limited to Web applications).

BSDCan-2011 - Brooks Davis - Improving System Management with ZFS
The Zetabyte File System (ZFS) is a modern file system which combines traditional file system features like a POSIX file system interface with RAID and volume management functionality. Features such as snapshot management and file share management are all managed within the ZFS interface. This management interface provides a number of opportunities to simplify system management. In the Technical Computing Services Sub-division of The Aerospace Corporation we are taking advantage of these features in a number of different ways. This talk presents some of the more interesting ones.

BSDCan-2010 - Kris Moore - The PBI format re-implemented for FreeBSD and PC-BSD
The PBI format (Push Button Installer) has been the default package management system for PC-BSD going on 5+ years now. However as we looked to the future it became apparent that it was greatly needing an overhaul to both improve its functionality, and expand its usage outside the scope of just PC-BSD. Among the areas needing improvement were how it dealt with identical libraries between applications, the heavy requirements from being implemented in QT/KDE, and lack of a digital verification mechanism.
