There’s no official announcement yet, but FreeBSD 8.1-RELEASE is available on the FreeBSD FTP servers:
DAHDI (Digium/Asterisk Hardware Device Interface) is the open source device interface technology used to control Digium and other legacy telephony interface cards.
“The purpose of DAHDI/FreeBSD project is to make it possible to use FreeBSD as a base system for software PBX solutions.
DAHDI (Digium/Asterisk Hardware Device Interface) is an open-source device driver framework and a set of HW drivers for E1/T1, ISDN digital and FXO/FXS analog cards (http://www.asterisk.org/dahdi/). Asterisk is one of the most popular open-source software PBX solutions.
The project includes porting DAHDI framework and HW drivers for E1/T1, FXO/FXS analog and ISDN digital cards to FreeBSD. This also includes TDMoE support, software and HW echo cancellation (Octasic, VPMADT032) and HW transcoding support (TC400B). The work is ongoing in the official DAHDI SVN repository with the close collaboration with DAHDI folks at Digium.
The project is nearing its completion: DAHDI framework and HW drivers telephony cards has been ported and tested. There are a number of success stories from early adopters who use E1/T1 and FXO/FXS cards on FreeBSD for several months.”
Congratulations, Max, for receiving the grant. It’s great to see FreeBSD branching out into another specialist area. AskoziaPBX used to be based on FreeBSD, but hardware support issues made the team decide to move to a Linux based PBX solution. Hopefully we will soon see another fully FreeBSD based PBX system (Askozia, Michael Iedema?)
The New York City BSD Conference (NYCBSDCon) is the main technical conference on the US East Coast for the BSD community to get together to share and gain knowledge, to network with like-minded people, and to have fun. This event is organized by members of the New York City *BSD Users Group (NYC*BUG).
This bi-annual event will be held at Manhattan’s prestigious Cooper Union on November 12-14, 2010.
The NYCBSDCon program committee is now accepting submissions presentations surrounding the BSD operating systems. The committee is looking to attract a wide range of speakers and attendees.
Each talk is expected to be 45-50 minutes, including a few minutes for questions and answers. All presentations will be recorded for audio and video. Presenters will have audio/visual and network connectivity.

One of the features that sets FreeBSD apart from other open source opeating systems, is its governance structure. FreeBSD is not owned by a company, though many companies use it and contribute code back, but yet is run as if it were a company, with the Core Team taking decisions and steering the Project.
The FreeBSD Core Team would be equivalent to the board of directors if the FreeBSD Project were a company. The primary task of the Core Team is to make sure FreeBSD, as a whole, is in good shape and is heading in the right directions. It is also responsible for approving new sourc committers, resolving disputes between developers, and appointing sub-committees for specific purposes, including responsibility for security advisories (the Security Officer Team), release engineering (the Release Engineering Team) and managing the ports collection (the Port Manager team). The Core Team has been elected by FreeBSD developers every 2 years since 2000.
The FreeBSD Project has completed the 2010 FreeBSD Core Team election, with the following developers elected:
- John Baldwin
- Konstantin Belousov
- Wilko Bulte
- Brooks Davis
- Warner Losh
- Pav Lucistnik
- Colin Percival
- Hiroki Sato
- Robert Watson
Congratulations to all (re)elected and we wish the new team the best for the next 2 years. May FreeBSD 9 and FreeBSD 10 become the best open source systems ever.
How the FreeBSD Project works
The FreeBSD Security Team have identified a little bug in FreeBSD where a lost mbuf flag can result in data loss.
An mbuf is a basic unit of memory management in the FreeBSD kernel inter-process communication and networking subsystem. Network packets and socket buffers are dependent on mbufs for their storage.
Data can be embedded directly in mbufs, or mbufs can instead reference external buffers. The sendfile(2) system call uses external mbuf storage to directly map the contents of a file into a chain of mbufs for
transmission purposes. The mbuf object supports a read-only flag that must be honored to prevent modification or writes to buffer data in cases like these.
II. Problem Description
The read-only flag is not correctly copied when a mbuf buffer reference is duplicated. When the sendfile(2) system call is used to transmit data over the loopback interface, this can result in the backing pages
for the transmitted file being modified, causing data corruption.
This data corruption can be exploited by an local attacker to escalate their privilege by carefully controlling the corruption of system files. It should be noted that the attacker can corrupt any file they have read
For a workaround and steps to fix this, have a look at the announcement
I Running old binaries on -current
Did you know you can old FreeBSD binaries on recent versions? As strange as it may sound, all FreeBSD versions have an ABI compatibility with previous versions, and you can run files compiled years ago. However, there seems to be a little problem now with running 1.0 packages on Current (9.0). Should be fixed soon. (via)
II Benchmarks of FreeBSD 8.1 RC2 against FreeBSD 8.0, Ubuntu Linux 10.10
Phoronix has tested the above three operating systems and compared them. It’s maybe like comparing apples with pears, but nonetheless interesting benchmarks: Benchmarks Of FreeBSD 8.1 RC2 Against FreeBSD 8.0, Ubuntu Linux
FreeBSD 8.1 is slated to be released this month as the first significant update to FreeBSD since the rollout of the 8.0 release last November. With the second release candidate of FreeBSD 8.1 having just been made available a few days back, we have conducted a set of tests comparing the performance of FreeBSD 8.1 RC2 versus FreeBSD 8.0 and an Ubuntu 10.10 development snapshot.FreeBSD 8.1 is slated to be released this month as the first significant update to FreeBSD since the rollout of the 8.0 release last November.

IV Something More Revelant then bsdstats.org
Generally bsdstats.org is only known by BSD users (and definitely not by all of them), so even having BIG stats out there is more or less pointless.
But there is other way to ‘impress’ other people with BSD stats … http://distrowatch.com portal. It mainly focuses on Linux distributions but it also gathers stats for BSDs and OpenSolaris/Solaris ‘distributions’.
How to do this: Something More Revelant then BSDSTATS.org
I came across warBSD the other day. Has anybody ever used it and if so, what is your experience. Please share in the comments below.
WarBSD was an attempt at using FreeBSD with the PicoBSD build scripts to make a *BSD based war driving kit.
Serve an anonymous shell via Tor
“While most people use Tor simply for anonymous web browsing, Tor also provides a slick way to host a service (web site, IRC chat server, etc) called a Hidden Service. These services are “hidden” because they are only accessible via the Tor network, and are under the same anonymity umbrella as Tor clients — unless they accidentally expose information about themselves, it is essentially impossible to determine the source location of the service.” continues

I Resource Containers Project
This project will be undertaken by Edward Tomasz Napierala. “Unlike Solaris zones, the current implementation of FreeBSD Jails does not provide per-jail resource limits. As a result, users are often forced to replace jails with other virtualization mechanisms. The goal of this project is to create a single, unified framework for controlling resource utilisation, and to use that framework to implement per-jail resource limits. In the future, the same framework might be used to implement more sophisticated resource controls, such as Hierarchical Resource Limits, or to implement mechanisms similar to AIX WLM. It could also be used to provide precise resource usage accounting for administrative or billing purposes.”
“It’s great that the Foundation decided to fund this project. It will make jail-based virtualization a much better choice in many scenarios, for example for Virtual Private Server providers.”
II DTrace Userland Project
DTrace is a general purpose and lightweight tracing framework that allows administrators, developers and users to investigate causes of system failure or performance bottlenecks. The FreeBSD operating system has had support for kernel-only DTrace since FreeBSD 8.0, but DTrace userland support was missing. Having userland support in DTrace allows inspection of userland software itself and its correlation with the kernel, thus allowing a much better picture of what exactly is going on behind the scenes.
This project will first concentrate on adding libproc support for symbol to address mapping, address to symbol mapping, breakpoint setup and the rtld interactions with DTrace. Next it will focus on DTrace process control, importing the pid provider and adapting it to FreeBSD and porting the userland statically defined probe provider (usdt). Finally it will bring in the plockstat provider.
“By having userland DTrace support, companies can make their products perform much better on FreeBSD due to the fact that they now have access to this amazing tool. When we mix the userland support with the kernel side DTrace support, we can also make FreeBSD a better operating system because we can investigate performance bottlenecks much easier.”
said FreeBSD developer Rui Paul
Well done to Rui and Edward. We’re looking forward to testing the results of their work at the end of the year. If you wish to see more of these sort of projects, you can donate to the FreeBSD Foundation.
“The PC-BSD project brings a user-friendly pre-configured KDE desktop to the FreeBSD community. Which is all well and good, but what if you’re more of a GNOME person? Well, it turns out there is a project in the works for you too. The GhostBSD project is in its early stages, but it’s paving the way for users who enjoy running GNOME on a FreeBSD base without any configuring or installing extra software. I had a chance to exchange emails with Eric Turgeon, the project’s founder and lead developer.”
