As the BSD projects (including DragonFlyBSD, FreeBSD, NetBSD, and OpenBSD) have grown in size,
a number of persistent myths have grown up around them. Some of these are
perpetuated by well meaning but misguided individuals, others by people
pursuing their own agendas.
This page aims to dispel those myths while remaining as dispassionate
as possible.
Note: Throughout this page, ``*BSD'' refers to all
of the BSD Projects. Where a myth or response is specific to a
particular project it is indicated as such.
Myth: *BSD has a closed development
model, it's more ``Cathedral'' than ``Bazaar''
Eric Raymond wrote an influential paper, ``The
Cathedral and the Bazaar'' in which the Linux development model
(and the model Eric used for fetchmail) is held up as an
example of how to do ``open'' development. By contrast, the model
employed by *BSD is often characterized as closed.
The implicit value judgment is that ``bazaar'' (open) is good, and
``cathedral'' (closed) is bad.
If anything, *BSD's development model is probably
more akin to the ``bazaar'' that Eric describes than
either Linux or fetchmail.
Consider the following;
All the *BSD projects: The current, bleeding edge source
code for FreeBSD, NetBSD, and OpenBSD is available for anyone to download
from the Internet, 24 hours a day. You don't need to wait for
someone else to roll a release.
FreeBSD: An installable snapshot of the current
progress is made weekly. These snapshots can be installed
exactly like an ordinary release, and do not require installation
over an existing system.
OpenBSD: Installable snapshots are generated daily and if
Theo thinks they are good enough, he uploads them to the mirrors.
Contrast this with Linux, where new kernel distributions are
made available on an ad-hoc basis, and where the frequency of
each Linux distribution release is at the whim of the individual
vendor.
There's none of the Linux fanfare every time a new kernel is
released, simply because for most *BSD users it is an every day
event.
Anyone can submit patches, bug reports, documentation, and
other contributions. They can do this
by using a web based
interface.
Pointers to this system litter the documentation.
Not everyone can commit code changes to the *BSD code. You
need to be a committer first. Typically, people are offered
``commit privs'' after they have made a few well-thought out
submissions to the project using Bugzilla or similar.
This is identical to the Linux mechanism. Only one person is
(notionally) allowed to change the Kernel, Linus. But specific areas
(such as the networking code) are delegated to other people.
Aside: Nik (nik@FreeBSD.org) is a case in point. After making
several submissions to the FreeBSD Documentation Project and
web pages, he was offered ``commit privs'' so that he did not
have to keep bothering other committers to commit the changes. He
never had to ask for them, they were freely given.
Myth: You cannot make your own distributions
or derivative works of *BSD
You can. You just need to say in the documentation and source
files where the code is derived from. Multiple derivative
projects exist:
Debian
GNU/kFreeBSD is a port of the Debian GNU userland
tools to the &os; kernel. It takes advantage of the devfs(8)
implementation (versus three discordant Linux interfaces),
security features (like jails, ipfw, and pf), and ZFS, among
other things.
DesktopBSD is
another FreeBSD based operating system
customized for desktop usability.
DragonflyBSD
started as a code fork from
FreeBSD 4.X, but it has since its own user community and
development goals.
Frenzy is
another live-CD distribution, but customized
for administering tasks. It contains software for hardware
tests, file system checks, security checks, network setup
and analysis.
Gentoo/FreeBSD
is an effort by the Gentoo Project to port their complete
administration facilities to take advantage of the reliable
FreeBSD kernel and userland. This project is purely
incomplete and experimental.
NanoBSD is another
project to produce reduced versions
of FreeBSD to put it on a Compact Flash card or other mass
storage. It is also a part of the FreeBSD source tree, see
/usr/src/tools/tools/nanobsd.
TrueOS is a desktop
oriented FreeBSD derivative. It is
intended to be easy to install and well-supported by its
community.
PicoBSD
is a tailored distribution of FreeBSD that fits
on a floppy. It is great for turning diskless 386 PC into a
router or a network print server. It is a part of the FreeBSD
source tree, see /usr/src/release/picobsd.
ThinBSD is a small
FreeBSD based boot image that allows a standard PC to act as
a diskless thin client for a Microsoft Windows RDP server or
an X terminal. It is entirely configured via DHCP.
TinyBSD is
a set of tools made up of shell scripts designed to allow easy
development of Embedded Systems based on FreeBSD.
TrustedBSD
provides a set of trusted operating system
extensions to the FreeBSD operating system, targeting the
Common Criteria for Information Technology Security
Evaluation (CC). This project is still under development,
and much of the code is destined to make its way back into
the base FreeBSD operating system, but the development
takes place separately.
pfSense is an open source
firewall derived from the m0n0wall firewall system with several
different goals and features, such as OpenBSD's Packet Filter (PF),
FreeBSD 6.1, ALTQ support for excellent packet queuing and
finally an integrated package management system for extending the
environment with new features.
The Whistle Interjet: A ``network appliance'' that acts as a
router, web server, mailhost (and other functionality), and can be
configured using a web browser. The underlying operating system is
FreeBSD, and Whistle have contributed many of their code
enhancements back to the FreeBSD project (while keeping enough of
them proprietary that they can stay in business).
Similarly to DragonflyBSD, OpenBSD was not a standalone project,
it started as a spinoff from the NetBSD project, and has since evolved
its own distinctive approach.
Myth: *BSD makes a great server, but a poor
(&unix;) desktop
*BSD makes a great server. It also makes a great desktop. Many of
the requirements for a server (responsiveness under load, stability,
effective use of system resources) are the same requirements as for a
desktop machine.
*BSD has access to the same desktop tools (KDE, GNOME, Firefox,
windowmanagers) as Linux. And ``office'' applications such as
OpenOffice suite work under *BSD too.
Myth: The BSD codebase is old, outdated, and
dying
While the BSD codebase may be more than 20 years old, it is neither
outdated nor dying. Many professional users like the stability that years
of testing has provided FreeBSD.
Myth: The *BSD projects are at war with one another,
splinter groups form each week
No. While occasional advocacy may get a touch heated, the *BSD flavors
continue to work with one another. FreeBSD's Alpha port was initially
heavily based on the work done by the NetBSD team. Both NetBSD and
OpenBSD used the FreeBSD ports collection to bootstrap their own port
sets. FreeBSD and NetBSD both integrate security fixes first discovered
by the OpenBSD team.
The FreeBSD and NetBSD projects separated more than twenty years
ago. OpenBSD and DragonflyBSD are the only new BSD projects to
split off in the last twenty years.
Myth: You can't cluster *BSD systems (parallel
computing)
The following URLs should disprove this;
http://www.epm.ornl.gov/pvm/
The Parallel Virtual Machine is nothing more than a software package that makes
setting up a Cluster simple. The source code is freely available, and will run
on FreeBSD without much problem.
The free software community started running on predominantly BSD
systems (SunOS and similar). *BSD users can generally compile software
written for these systems without needing to make any changes.
In addition, each *BSD project uses a ``ports'' system to make the
building of ported software much easier.
FreeBSD: There are currently more than 26,000
applications ready to download and install in the FreeBSD ports
collection. On i386 and AMD64, the Linux emulation layer will
also run the vast majority of Linux applications. On the AMD64
architectures there is a compatibility layer to run 32-bit FreeBSD binaries.
NetBSD: The Linux emulation layer will run the vast majority of
i386 Linux applications, and the majority of SunOS4 applications can be
run on a SPARCStation.
OpenBSD: There are currently more than 3700 applications
ready to download and install in the OpenBSD ports collection. The Linux
emulation layer will also run the vast majority of i386 Linux
applications, and the majority of SunOS4 applications can be run on a
SPARCStation.
Both NetBSD and OpenBSD are able to use applications in FreeBSD's ports
collection with minimal effort. Their lower number of ported
applications reflects this.
It is true that most companies when porting to PC Unix will choose Linux
first. Fortunately, *BSD's Linux emulation layer will run these
programs (Acrobat, StarOffice, Mathematica, WordPerfect, Quake, Intel
ICC compiler, Compaq's Alpha compiler ...)
with few, if any, problems.
As a historical note, the first version of Netscape Navigator that ran
on FreeBSD with Java support was the Linux version. These day you can
also use a native FreeBSD version of Mozilla with a native Java
plugin, all compiled conveniently from ports.
Here are the projects currently under way (or being actively
contemplated on the freebsd-doc mailing list).
If you think you can contribute to any of these, please do not
hesitate to stand up and be counted. You should talk to the
person responsible for that particular project, who can then bring you
up to speed on what is happening. If you have any ideas for a new
project then please email
FreeBSD-doc@FreeBSD.org.
The Documentation TODO
list is an
up-to-date list of documentation issues that should be resolved.
If you wish to help us to improve the FreeBSD
documentation set you should, at first, choose to work on one of
the TODO list items.
Open documentation problem reports
Current FreeBSD problems reports are tracked using a Problem Reports
database.
You can view
the open documentation problem reports.
Synopsis: Many new sections have been added to the
FreeBSD Handbook without index terms, others have been added
under inappropriate primary or secondary indexterms that do not
fit the existing scheme. Some indexterms have been added inside
list items or other areas where they are not allowed by our
stylesheets, causing ??? to be printed in the index instead of
a real page number.
Index work requires experience and anyone who works on this
task is highly encouraged to carefully read through the existing
(print-output) index, and to have read the Chicago Manual of
Style or other style books that deal with indexing. Please see
the SVN history of some of the chapter.xml files to see some of
the indexing errors that have been corrected in the past.
It is imperative to view the PostScript version of the Handbook
after making any changes to indexterms as many errors, such as
long words or deeply nested indexterms will break the two column
output there, or cause the page number to be listed as ???.
There is a script doc/share/misc/indexreport.pl which
can be used to find areas of an SGML file where
<indexterms> are sparse.
Synopsis: Presentations marked up in the DocBook-slides
DTD have recently been added to the documentation set in
doc/en_US.ISO8859-1/slides. More advocacy content is
needed, and additional stylesheet work is needed to pull in
content from the release notes and other XML content in our
documentation set to build up-to-date slides with 'make'. A
simple example presentation was committed with some of this
functionality, but there is more work to be done! Also, the
stylesheets for print/PDF output (using the Java based XSLT
processors, PassiveTeX is too limiting for slides) could be
improved as the default DocBook Slides XSL-FO stylesheets
produce very spartan slides.
Synopsis: Chunks of the FAQ and Handbook have empty sections in
them. They need filling. If you have just had to use one of
these documents to complete a task, and found them lacking,
please find the time to write up your experiences as a
possible replacement.
Alternatively, if you have just had to do something that had no
entry in the FAQ and/or Handbook, please consider writing a
new section. Then submit it as outlined above.
Synopsis: Modify the CGI script ports.cgi
and the script portindex to use the Perl FreeBSD::Ports
+ href="https://people.FreeBSD.org/~tom/portpm/">FreeBSD::Ports
modules. These modules also need thorough testing.
Our main Web pages are written in (American) English. The FreeBSD Translations Projects
translate the web pages, Handbook and FAQ to other languages.
We must translate the cgi scripts and web build scripts too. The
scripts should support multiple languages, not only one.
Most scripts are written in perl.
The third FreeBSD Developer Summit was held on June 11-12, 2002, at
the Monterey Marriott in Monterey, CA, immediately prior to the USENIX
Annual Technical Conference at the same location. The FreeBSD
Developer Summit was sponsored by DARPA, the FreeBSD Foundation, FreeBSD Mall, Network
Associates Laboratories, and AT&T. Notes were taken by George
-Neville-Neil, Bruce Mah,
+Neville-Neil, Bruce Mah,

individual and then a discussion ensued. Not all of the discussion
was caught but we have tried to make those sections
understandable.
09:30 Opening Remarks
KSE - Julian Elischer
KSE has not changed much since the last summit (Feb). The major
change is that upcalls works more like signals instead of like fork().
That is to say that you give the system a function pointer to call
instead of having the "return twice" semantics so that it supports
all architectures.
The names in the system are deliberately different from other
threading packages. This was to reduce confusion during
development.
The process structure has been broken into 4 parts. This is in
-CURRENT at the moment. It's still "really" one structure but is
being accessed as 4 different ones.
Looking for more people to run the code.
Right now we're rewriting to clean up how the functions work.
Other architectures can be stubbed out as well.
Right now there is no support for Sparc or IA64 but he would like
to commit now. Not committing now means that it has to come out of
perforce and people have to patch it.
Discussion
rwatson : What about userland?
julian : It can run different threads
in userland. The primitives are all there it just needs a bit more
help. I would like to put an idea out. Is it a good idea to be able
to have non-threaded programs linking with threaded libraries?
rwatson : Putting async I/O into such a
thing would make sense.
julian : The library would not care
who was accessing it.
rwatson : For instance libc could be
threaded or not.
julian : That would be interesting. I
don't know if the two interfaces are incompatible.
jhb : X does this.
dillon : It is very doable but you
have to make it non-preemptive. If you're switching non-preemptively
you can use library routines which are non threaded.
julian : If I do what I'm thinking of
doing then each lib will have its own KSE group.
dillon : stdio does not have to be
thread aware if you don't schedule preemptively. It all matters where
it blocks.
julian : Since you're a non-threaded
program you don't know that.
rwatson : If you're going to support
that, libc has to support threads.
rwatson : It sounds like some
complexity goes away. Can we use 1 libc with has threading?
julian : Do we want to go down this
path?
rwatson : Now or later?
julian : What do I design now to do
this?
jhb : For example libc_r does not
work with rfork.
julian : The answer is that yes we
should move forward. Tricky issues, signals...
warner : Have people talked about
pthread programs and cancellation points?
julian : The pthreads library does not
assume that you're only going to change threads at yield() points. We
are going to have cancellation points. There is an unimplemented call
which will be able to send a thread targeted signal even into the
kernel.
julian : When a thread is scheduled
onto a KSE there is a mailbox that the userland thread scheduler
updates.
julian : Is there anyone else who has
some time or test it? How many people should test this before I check
it in? There is a patch that's continuously updated on my web site to
be able to patch it to -CURRENT. There is a CVSUP target from cvsup
10 which will bring down the sources. If you go to my web page on
freefal there is a pointer there to a web page that explains how to
CVSUP from source.
rwatson : What about SMP locking for
this?
julian : Handled by the proc locking.
Has not been tried on SMP machines yet.
obrien : What about on Sparc?
julian : You may need to stub things
out.
jhb : Is the paper on the web site?
julian : The updated copy has disappeared.
unknown : What's the different between
NetBSD and FreeBSD on this?
julian : Logically not a tremendous
difference but Net follows the paper closely and Free takes the idea
and makes it into a production system. There were some tough battles
on -arch about this. The tricky point is that the proc structure has
to be broken into 4 instead of 2. If you want to be able to do POSIX
you need to be able to treated as different processes but in other
systems you need to group the threads. You wind up with two classes
of threads. You need another structure to do the aggregation. In the
end we ended up breaking up the proc structure into 4 pieces to not
overwhelm the CPU when scheduling threads. This is the major
difference.
julian : I greatly admire the NetBSD
way which is to take an idea and not dilute it.
julian : Net is also putting a Solaris
compatible threads package on top of their scheduler activations in
the Solaris ABI.
SMPng - John Baldwin
jhb : Yesterday we talked about SMP
related things so I'll give a summary and then give a list of things
for 5.0.
jhb : The big thing for 5.0 is to
get the network stack out from under Giant.
jhb : Jeffrey Hsu and Jennifer Yang
were here to talk about this. They have the PCBs checked in now.
jennifer : Interface Queues and SynCache
might be done.
The remaining chunks of the network code are:
Routing Table Locking
Socket Buffers
ifa structures
struct ifnet
locking ipfw and dummynet
other (non IPv4) protocols
Netgraph
jhb : Aside from network the newbus
locking needs to be done (Warner Losh) and also CAM stuff. No known
status on CAM. Perhaps CAM is not needed for 5.0
jhb : Disk drive interrupts? Would
help performance. Going to talk to Poul Henning-Kamp
jhb : Alan Cox is working on the VM
system. Working based on the old Mach stuff. Objective for 5.0 is to
get zero fill and execute on write to work without Giant. In future
he wants to look at locking down pmap() functions.
jhb : Still some stability issues.
UMA breaks some assumptions. For instance sockets assume that once
memory is a socket its a socket forever, this is no longer true.
jhb : Talked to Mike Smith about
5.0 and have decided to stop adding features so that we can start
clean up 5.0 and make it a real release. This might require hacks.
rwatson : For example in the UMA case
there could be a flag to just say "don't reclaim this zone" -- this
would help with issues such as the socket code assuming memory is type
stable.
Over to Alan Cox on the VM system.
alc : Nothing to say.
bmilekic : As much as I might get hated
for this. Will preemption stuff go in by 5.0?
jhb :No, that's a 6.0 thing. There
are things to do first.
unknown : Could this come in in
the life time of 5.? 5.1?
rwatson : This is a release issue really.
jhb : Yes, the kernel is pre-emptive.
rwatson : Perhaps we should talk about
is performance goals? What are the comparisons to make? Perhaps head
of 4 with head of 5. We'll see a mix.
jhb : I need to run benchmarks.
rwatson : In terms of SMP features when
will VM be ready to be measured? I can't put a date on it.
alc : I think I told John was in
time for release. I'm already doing performance testing so we've
already started.
rwatson : We'll pick a date to start
doing measurements. Perhaps 2 or 3 weeks from now.
alc : My guess is the the locking
pmap is going to take some time to shake out. On the other hand the
next major module we should be working on is machine dependent level.
Last we should try approaching the vmobject level. I'll start
worrying about performance in the near term.
rwatson : Will threading improve
latency or throughput for networking?
bmilekic : I would like if we could
actually start before.
rwatson : Do you have a timeline for
the interrupt threading stuff?
bmilekic : I finished some things last
night but there are still issues. In a couple of weeks it should be
ready for first commit.
rwatson : Informally beginning to
measure performance now. What are the right sets of tests? Need to
discuss on -arch.
alc : It would be nice to have that
committed to the tools directory.
jhb : The statistics analysis
package are we using.
bmilekic : I have some good success with
netpipe for overall measurement.
rwatson : Need to be using consistent
compilers because of the compiler change. Also all our debugging
stuff will slow down the benchmarking.
Benchmark Ideas
chroot of 4.6 area for testing
buildworld
build X11R4 w/gcc 2.95
netpipe on loopback
end to end testing on on gigE cards
(throughput,connections/sec)
thread stuff like mySQL
Kirk's FS benchmarks
NFS Tests (nfsstone)
Sleepycat DB tests?
Tests to be run on:
4.6-RELEASE
5.0-DP1
5.0-DP2
5-CURRENT
4-STABLE
Targets:
alpha, i386
UP, 2/4-way SMP, SMP with one processor
low/high memory
slow/fast CPU
dillon : Debug stuff on 5.0. I think
it might be reasonable then to take the space hit and always have the
debugging in but turn it on and off with sysctl.
rwatson : We should commit an optimized
kernel configuration and benchmarking guidelines to the tree as
well.
&break;
rwatson : I think we should continue
the performance discussion. We want to accomplish a couple of things.
One is stability measurement. What are the things we need to be
measuring? What is our definition of useful?
hsu : End to end measurement
with gigabit cards. For latency test connections per second. Can use
ttcp or netbench in ports.
gnn : need to make sure we run
against all of 4.6
julian : Need to really have 3 tests.
4.6 (forever) 4.x (following updates) and -CURRENT.
rwatson : There are other dimensions.
Degree of parallelism for instance. We might see degradation in uni
but get good stuff in multi case.
julian : Test for impact of KSE
complications as well.
alfred : I think as the results come
through people should not be too worried about it. Perhaps we should
benchmark database type stuff as well. Need to do something
comprehensive.
obrien : What does the test matrix
look like? Different architectures and different numbers of
processors.
rwatson : Can we make a multi-processor
run uni-processor.
alfred : Run queue and scheduler stuff?
julian : Will talk to Alfred.
rwatson : Is scalability testing
important?
obrienM : NFS testing.
rwatson : What about UI testing?
hsu : x11perf is the way to do that.
dillon : Currently we have a directory
for regression tests, should we do one for performance tests?
gnn : talk to sleepycat for DB
tests, see if they have some
alfred : Really nice to tests DB
applications that are heavily thread dependent.
hsu :Apache 2 has threads.
rwatson : What about commercial folks?
What do you do.
ps : Normally what we end
up doing is using the snapshot on some machines and see if the bugs
are out. There is no performance testing really.
rwatson : Again, what about performance?
ps : We've really never had
one. It's more just bugs. We've just never found the performance to
be a problem.
rwatson : We need to create a forum for
talking about performance. We need reproducible test cases.
ps : There's also other
things. We've been doing lots of looking at this. FreeBSD gets
kicked down by attacks for instance. We have a lot of tools to get to
the project though.
rwatson : I will set up the mailing
list.
New Hardware Architectures
Alpha
jhb : Questions about alpha?
rwatson : KSE on alpha?
julian : We have patches so it
compiles and runs non-KSE programs. You can have the patched version
of the alpha kernel up and running though.
rwatson : Is the task owned of making
this work on Alpha?
IA64
dfr : It works as far as I get to
use it. It's not used in production right now.
ps : Intel shipped me a quad
processor IA64 board. (McKinley is the name of the board).
rwatson : What does it need for 5.0?
dfr : It works, it works for SMP.
Self hosts, build worlds. sysinstall compiles but needs more kicking
to work.
ps : Intel wants us to ship
a CD.
dfr : There is no thread support
right now (threading library needs to move to get/setcontext rather
than longjmp).
dfr : Need to move every driver to
use BUS DMA for large memory machines to get bounce buffers.
jhb : PHK is working on using a new
libwhisk so that sysinstall et al work on all systems.
Sparc64
jake : Take control of KSE stuff
on Sparc 64.
rwatson : Do we have a Sparc 64 in the
cluster?
jake : It's not in the cluster
yet. It's a serial cluster issue.
rwatson : Package building on S64?
jake : Perhaps a bunch of Ultra
60s for a package build.
obrien : 1500 build right now?
jake : Yes, but a lot of the
same bug in packages are broken.
jhb : Timeline for X?
jake : Not really.
rwatson : In terms of 5.0 how
comfortable are you?
jake : sysinstall is the only problem.
PowerPC
benno : I got it up to
execing a fake init in the simulator and printing "hello world".
Trying to work with real hardware. I now have some semblance of
busdma and am working on other stuff. GEM on iMac is in an embryonic
state. Should get to NFS mount in a few weeks.
rwatson : How do you feel about your
timeline?
benno : I'm not sure we'll have
something fully workable for 5.0.
rwatson : You're not at the point yet
on working on KSE are you?
benno : No, need a useful system
first.
AMD64
rwatson : I know that we're having
simulator problems.
obrien : The issues are about legal
and NDA. AMD decided on FreeBSD
Mall as the NDA person. I have not had a working simulator since
September.
ps : I can make that happen, as
well as real hardware.
obrien :I've got a cross tool chain in
the tree. I have some untested pmap stuff. Hardware has been
available for a month or so. We could boot FreeBSD 4.6 today if only
we had hardware.
rwatson : What do you think about 5.0?
Should we discuss that at another date?
MIPs
unknown :Juniper offered.
obrien : But we have no hardware.
unknown :Juniper thinks it's OK but
doesn't want to have it rot in the tree.
brooks : I have a line on a company
that does compact PCI with R6Ks.
rwatson : We're waiting for someone to
turn up.
LUNCH
Trusted BSD
rwatson : Malc framework is what is of
interest today.
See Slides from Robert
julian : Are the labels the same on
all structures?
rwatson : You can modify this but there
are issues with memory: is the space needed for a label too large to
add to an mbuf header, for example? The label is small, but there
area lot of them?
bmilekic : When you're freeing the mbuf
do you write the label data?
rwatson : We blank it when we free it.
bmilekic : I do not think the 36 bytes
in the mbuf header is a problem.
julian : I'm more interested in the
"why" than the how.
rwatson : A lot of people are
interested in this. Some of the things that do interest a lot of
people are things like doing on the fly security for a web server.
julian : Is there a black hatted TLA
interested?
rwatson : Yes and several gov'ts. As
well as plenty of financial folks.
rwatson : There's a lot of userland
stuff that's not done yet.
Release Engineering
murray : Shows a slide of releases.
4.6 is ready to go but having issues with ISO images. DP1, a lot of
goals were met. 1000 packages were building on -CURRENT to get DP1
out. Polished 4.2. We need to start making decisions on 5.0.
November is still the date we're shooting for. We're going to do a
4.7 and a 4.8. DP3?
***GET SLIDE FROM MURRAY***
murray : Release engineering area of
the web site www.FreeBSD.org/releng. For DP2 question about p4 or

removal? KSE?
julian : KSE should be able to run
simple tests.
obrien : Is whatever you have
committed by DP2 be the same as the release.
julian : It will be a subset.
murray : What will the status be of
KSE in userland for 5.0?
julian : Can't answer that right
now. We're not removing the old libraries. The userland work will
happen between DP2 and release. The next step is MP as well as
UP.
obrien : Are we heading for a release?
murray : yes.
obrien : Then we have to stop having
major commits.
murray : Yes, the discussion today is
what are the major must have features.
rwatson : We need to decide if there
are major upcoming problems and reduce risk on things like KSE.
julian : That's why I want to get milestone 3
in now.
rwatson : Do you think that KSE related
changes from later milestones are going to be isolated to KSE or
pervasive?
julian : Hard to say. My guess is
that milestone 4 stuff should be less pervasive.
rwatson : What happens if KSE just
doesn't work?
julian : Well it does work, the
patches work, it's a question of risk. We need to check on new
things, like locking two threads in the same process.
dillon : KSEs only become fragile when
pthread uses them. That's the turning point.
obrien : I'd like the rules for the
rest of the summer, I hope we'll talk about that.
murray : Earlier is better.
mini : I think the cutoff point for
KSE might be milestone 3.
rwatson : It's the kind of thing where
if we need to back out we can.
julian : If you're not going to run
KSEs then you're OK.
rwatson : I think it's low risk. Let's
avoid the risk is the message.
julian : The next DP2 (where we'd like
milestone 4).
alfred : We really need KSE so all
this concern about stuff that no one really uses is not a big deal.
People just need to play catch up. We have performance problems and
we need to solve those.
obrien : We quickly need to figure out
our policy on multiple archs.
rwatson : I briefly want to respond to
Alfred. We have asserted that KSE will be experimental. It will be
in and 5.0 will go out but there might be issues.
jhb : Realistically for the network
stack is that IPv4 sockets will not be giant. But this is only in the
network stack world. Several people are working on it.
rwatson : The GEOM stuff will be
enabled by default in 5.0. Sparc depends on it. I do not know what
the impediments are to that though.
julian : The kernel stuff is there but
the user space is not. It can't become the default until everything
is there.
warner : What level of control are you
going to exercise over the tree in the coming months?
murray : You're going to see more
level of control but we expect the requests to be reasonable. It's a
very open process.
jhb : How are we going to address the
5/6 split?
murray : Carefully is all I can
say.
rwatson : For 5. 0 we need to have a
more informed decision. The release engineers will be trying to
reduce the number of large code changes more as time goes by. We
don't have to wait for 5.x to be perfectly stable before we branch.
murray : Let's move it to more general
discussion of DP2? Specific technologies.
bmilekic : Is there a strategy to lock
other protocols that are not locked down onw?
obrien : How much more do we need to
do before 5.0?
jhb : Bug fixing is what we're doing.
rwatson : The answer on the network
stack. We need to choose a strategy on how to handle the other
protocols.
obrien : The crux is that socket
locking must be in 5.0.
rwatson : There are 2 or 3 problems.
Routing code is a problem. See earlier discussions.
dfr : RCng is essentially done.
What it needs is testers.
alfred : What about libh (I think libh
is wrong but this is what I heard)?
jhb : It's very far along but not a
5.0 thing.
warner : Problems with interrupt
routing in ACPI?
takawata : Cannot handle PCI<->PCI
interrupt routing. Many 802.11x have this problem.
julian : Is it a problem from Intel?
takawata : This is not an Intel
problem but a problem on our side. PCI<->PCI routing code should be
added. New code is necessary.

rwatson : How broken is C++?
obrien : Only on sparc64. Don't
really know yet, but it's probably a library issue. The compiler is a
pre-release snapshot. The diffs are now getting large from May 5 to
now. We should attempt to be as far along this gcc branch as possible
come release.
&break;
rc.d
gordon : Talking about rc.d stuff.
Import from NetBSD. Right now we have patches out there that are
translated from the current boot order. It's in perforce. After the
conference it will go into the mainline. Single toggle for
booting.
rwatson : How in sync are the bits in
the new stuff with the old stuff.
gordon : Last patch is from June 3rd,
but it's tracking closely.
rwatson : What is the schedule for
committing to the main tree.
gordon : We have large patches so
we're going to re-import from NetBSD.
rwatson : How about you have it done by
July 1?
gordon : We could probably do that.
Definitely want to be in DP2.
gshapiro : How long will we keep the old
stuff for?
gordon : We'll keep them both in for a
while. Not more than 1.5 months though.
julian : Have you had a look at all at
the Mac OS/X startup code?
gordon : No.
julian : Do you deal with dependencies?
gordon : There is meta data in each
script that says what needs what. There is a program that orders
everything correctly.
unknown : How does this effect the rc
script for ports install?
gordon : We could make this available
to ports but won't on the first version.
alfred : Can I recommend that you
recommend this to ports?
gordon : Yes, the problem is that we
have so many ports.
rwatson : The reason for this is for
rebundlers of FreeBSD in their environments. We don't have to have it
for DP2 but it should be an ultimate goal. We might need to have a
policy statement on this. That at date X all ports must use the new
system.
Other Issues
sam : I've been working on hardware
crypto. I'm looking for consensus on getting hardware crypto in the
kernel. This will not happen in 5.0.
Syscall vector change for 64bits
dillon : Two ways to go. Need to
create a new syscall vector. The other is to do a 1 off replacement.
Prefer the former.
rwatson : Perhaps we need to create a
FreeBSD 5 syscall vector. Could be a new ABI.
julian : Aren't there enough other
numbers?
rwatson : That's one way to look at it
and other platforms have done that? Is that too heavy weight?
julian : It sounds that way to me.
You end up having to replicate the old ones into the new one.
dillon : The issue is about pollution.
dfr : Seems like too much work for 5.x
julian : It's more work. There are
now two places. Why not talk to OpenBSD?
rwatson : Should there be a BSD alfredI?
Tough to do across projects.
obrien : Who here is going to see that
through? We have not talked to NetBSD about even SMP.
alfred : Does changing the syscall
table allow us to do clean up?
rwatson : We could do that without
doing 64bit syscall table.
5.x ABI stability
rwatson : There are new functions in
5.x. At what point do we stop changing?
dfr : When people start really using it.
rwatson : How do we tell? How did
Solaris do it?
Everyone : No one knows.
dfr : It's too hard to add a
syscall vector. Library issues are a problem.
obrien : We can use ELF to handle that.
dfr : Let's just add 20 new
syscalls instead of adding new work that we don't really really need.
rwatson : Punt on lack of time to do
this.
dillon : I see obrien's point with the
libraries but I have done this with time_t at 64 bits.
devd
rwatson : The devd stuff was to
integrate cardbus, newbus, etc.
julian : To monitor requests to mount
or create new devices.
rwatson : Is this a 5.0 requirement?
Is there anyone to do this?
gordon (from IRC) : PHK has patches
that make having devd unnecessary.
brooks : Need something that does what
pccardd did.
julian : Need to be able to do this
through a file.
warner : (from IRC): That's a 6.0
feature.
julian : It would not be a large step
to put something in the middle to handle this.
julian : Sometime in the 5 lifetime we
need this.
warner : There is no way to monitor
events in newbus but it would be easy to add.
julian : I'm not sure I understood you
correctly.
warner : What happens now in a PCI is
that it makes a call to pci_get_devid() and the driver would say "yes
I am " or "no I'm not" so you'd have to change each of the busses to
do this but that's not too tough because we have a small # of
busses.
jhb : Mike Smith gave us an
informal tour of OS/X. OS/X uses XML to do this. They have the DEVID
in XML.
brooks : I looked at some PCI drivers
and some work that way but some don't.
julian : It seems to me we need to not
have to modify every single driver. If you've got a device that's not
supported you ask all drivers. At the point when you run out you make
an outcall. The outcall returns does a substitution.
The FreeBSD GNOME team proudly presents GNOME 3.18 for
FreeBSD.
This update does not contain the glib and gtk c++ bindings
which will be done in a another update due to the requirement
on c++11 and the amount of fallout this probably will give.
GDM is still at version 3.16 due to some issues.
Bump mate-themes to use the gtk 3.18 version of the themes.
January25Announcing MATE 1.12 for FreeBSD!
The FreeBSD GNOME team proudly presents MATE 1.12 for
FreeBSD.
This version of MATE uses the GTK+ 2 toolkit for
stability, and has a number of bugfixes for the
applets.
2015August5Announcing GNOME 3.16.2 for FreeBSD!
The FreeBSD GNOME team proudly presents GNOME 3.16 for
FreeBSD.
This release brings initial PackageKit support, Upower
(replaces power management part of hal), cuse4bsd
integration with HAL and cheese, and a faster
Evolution.
Sadly GNOME 2.30.x will be the last release with FreeBSD
6.X support. This will also be the last of the 2.x
releases. The next release will be the highly-anticipated
GNOME 3.0 which will bring with it a new UI
experience.
Currently, there are a few bugs with GNOME 2.30 that may
be of note for our users. Be sure to consult the 2.30
upgrade FAQ at
https://www.freebsd.org/gnome/docs/faq230.html>
for specific upgrading instructions, and the up-to-date
list of known issues.
This release features commits by: avl, ahze, bland,
marcus, mezz and myself.
The FreeBSD GNOME Team would like to thank Anders F
Bjorklund for doing the initial packagekit porting.
And the following contributors and testers for there help
with this release:
Eric L. Chen
Vladimir Grebenschikov
Sergio de Almeida Lenzi

and Ion-Mihai Tetcu for running two exp-runs for us.
2009November28Announcing GNOME 2.28.1. for FreeBSD!
Presenting GNOME 2.28.1 for FreeBSD. The official release
notes for this release can be found at
http://library.gnome.org/misc/release-notes/2.28/.
Officially, this is mostly a polishing release in
preparation for GNOME 3.0 due in about a year.
On the FreeBSD front, though, a lot went into this
release. Major thanks goes to kwm and avl who did a lot
of the porting work for this release. In particular, kwm
brought in Evolution MAPI support for better Microsoft
Exchange integration. Avl made sure that the new gobject
introspection repository ports were nicely
compartmentalized so that large dependencies aren't
brought in wholesale.
But, every GNOME team member (ahze, avl, bland, kwm,
mezz, and myself) contributed to this release.
Other major improvements include an updated HAL with
better volume probing code, ufsid integration, and support
for volume names containing spaces (big thanks to J.R.
Oldroyd); a new WebKit; updated AbiWord; an updated Gimp;
and a preview of the new GNOME Shell project (thanks to
Pawel Worach).
The FreeBSD GNOME Team would like to that the following
additional contributors to this release whose patches and
testing really helped make it a success:
Andrius Morkunas
Dominique Goncalves
Eric L. Chen
J.R. Oldroyd
Joseph S. Atkinson
Li
Pawel Worach
Romain Tarti?re
Thomas Vogt
Yasuda Keisuke
Rui Paulo
Martin Wilke
(and an extra shout out to miwi and pav for the pointyhat
runs)
We would like to send this release out to Alexander
Loginov (avl) in hopes that he feels better soon.
April10Announcing GNOME 2.26.0 for FreeBSD!
The FreeBSD GNOME team is proud to announce the release
of GNOME 2.26.0 for FreeBSD. The official release notes
can be found at
http://library.gnome.org/misc/release-notes/2.26/.
On the FreeBSD front, we introduced a port of libxul 1.9
as an alternative for Firefox 2.0 as a Gecko provider.
Almost all of the Gecko consumers can make use of this
provider by setting:
WITH_GECKO=libxul
The GNOME 2.26 port was done by ahze, kwm, marcus, and
mezz with contributions by Joseph S. Atkinson, Peter Wemm,
Eric L. Chen, Martin Matuska, Craig Butler, and Pawel
Worach.
January9Announcing GNOME 2.24.2 for FreeBSD!
The FreeBSD GNOME team is proud to announce the release
of GNOME 2.24.2 for FreeBSD. The official release notes
can be found at
http://library.gnome.org/misc/release-notes/2.24/.
On the FreeBSD front, this release introduces Fuse support
in HAL, adds multi-CPU support to libgtop, WebKit updates,
and fixes some long-standing seahorse and gnome-keyring
bugs.
This release features commits by adamw, ahze, kwm, mezz,
and myself. It would not have been possible without are
contributors and testers: Alexander Loginov, Craig Butler,
Dmitry Marakasov, Eric L. Chen, Joseph S. Atkinson, Kris
Moore, Lapo Luchini, Nikos Ntarmos, Pawel Worach, Romain
Tartiere, TAOKA Fumiyoshi, Romain Tartiere, Yasuda
Keisuke, Zyl aZ, bf, Florent Thoumie, Peter Wemm, and
pluknet.
2008March24Announcing GNOME 2.22.0 for FreeBSD!
The FreeBSD GNOME team is proud to announce the release
of GNOME 2.22.0 for FreeBSD. The official GNOME 2.22
release notes can be found at
http://library.gnome.org/misc/release-notes/2.22/.
On the FreeBSD front, this release features an updated hal
port with support for video4linux devices, DRM (Direct
Rendering), and better support of removable media. Work
is also underway to tie webkit more closely into GNOME. As
part of the GNOME 2.22 upgrade, GStreamer received a
rather large upgrade as well. Be sure to consult UPDATING
on the proper steps to upgrade all of your GNOME
ports.
This release would not have been possible without the
contributions and testing efforts of the following people:
Pawel Worach, kan, edwin, Peter Ulrich Kruppa, J. W.
Ballantine, Yasuda Keisuke, and Andriy Gapon.
2007October24Announcing GNOME 2.20.1 for FreeBSD!
Presenting GNOME 2.20.1 and all related works for
FreeBSD. The official GNOME 2.20 release notes can be
found at
http://www.gnome.org/start/2.20/notes/en/.
Beyond that, this update includes the new GIMP 2.4
(courtesy of ahze).
The GNOME 2.20 update also includes a huge change in the
FreeBSD GNOME hierarchy. We are now using the more
standard DATADIR of ${PREFIX}/share rather than
${PREFIX}/share/gnome. The result is that fewer patches
and hacks are needed to port GNOME components to FreeBSD.
This will mean some user changes may be required, so be
sure to read /usr/ports/UPDATING for more details.
This release and the things we accomplished in it would
not have been possible without mezz's crazy idea to
collapse DATADIR, and his persistence to make it happen
successfully. Ahze and pav also deserve thanks for their
work on porting modules and testing the whole ball of wax
on pointyhat (respectively).
The FreeBSD GNOME team would also like to thank our
various testers and contributors:
Yasuda Keisuke
Frank Jahnke
Pawel Worach
Brian Gruber
Franz Klammer
Yuri Pankov
Nick Barkas
Cristian KLEIN
Tony Maher
Scot Hetzel
Martin Matuska (mm)
Benoit Dejean
Martin Wilke (miwi)
(And anyone else I may have missed)
August4GNOME 2.19.6 available for FreeBSD
Okay, okay, I have missed a few updates. But the FreeBSD
GNOME team has not been slacking. We've been keeping up
with the latest GNOME development releases including this
latest one.
Check out the ports and
packages
to see where GNOME 2.20 currently stands. Since 2.10 Beta
1 is right around the corner, now is also the time to
start putting together some killer FreeBSD GNOME
screenshots. Send all submissions to
freebsd-gnome@FreeBSD.org.
June9GNOME 2.19.3 available for FreeBSD
The third release on the path to GNOME 2.20 is now
available in both port and
package
forms. There is one known build issue with
gnome-system-monitor and FreeBSD < 7-CURRENT that we
hope to have worked out soon. Along with this release
comes the GNOME 2.20 (and beyond!)
roadmap.
This will prepare you for the exciting new features in
store for our favorite Desktop Environment.
May31GNOME 2.18.2 available for FreeBSD
The next bug fix release for GNOME 2.18 has been
released
and ports and
packages
are available for FreeBSD. So the only question is, why
haven't you upgraded yet?
6GNOME 2.19.1 available for FreeBSD
GNOME forges ahead with the first release in the
development train that will become GNOME 2.20. As always,
FreeBSD is right there with them. Only we bring a twist.
This time around, we are doing yet another bit of
housekeeping, and dropping the "share/gnome" DATADIR.
This means that the FreeBSD GNOME installation will be
more like all the other GNOME distributions. The net gain
is that porting new GNOME applications to FreeBSD should
be much easier with fewer hacks and patches.
At this point, the
MarcusCom tree
is safe to use for most ports. There is still quite a few
ports that still require conversion, and we will be
working on those in the weeks to come. In particular, the
Desktop and all gnome2 meta-ports are safe; and
Packages
are available for the GNOME Desktop.
April11GNOME 2.18.1 available for FreeBSD
GNOME 2.18.1 has been
released
and ports and
packages
are available for everyone's favorite operating system.
This release is a polishing of 2.18.0, so expect a more
stable, nicer looking desktop experience. On top of that,
some of our users have also submitted
screenshots!
March19GNOME 2.18 release for FreeBSD!
Presenting GNOME 2.18 for FreeBSD. GNOME 2.18 is a
departure from recent GNOME releases in that it focuses
more on stability and functionality than on new features.
Not that it doesn't have its share of new and exciting
items. Check out the
official release notes
for all the goodies in this release.
GNOME 2.18 for FreeBSD would not have been possible
without the hard work of the
FreeBSD GNOME Team
and our intrepid band of testers including J. W.
Ballantine, Pawel Worach, Yasuda Keisuke, Pascal Hofstee,
miwi, Yoshihiro Ota, Vladimir Grebenschikov, Jukka A.
Ukkonen, Phillip Neumann, Franz Klammer, and Neal
Delmonico.
February28GNOME 2.17.92 available for FreeBSD
GNOME 2.18 is nigh! The 2.18 Release Candidate has been
released, and both
ports
and
packages
are now available for FreeBSD. We are
SO
close to a release, and yet we still don't have any
screenshots. So please, if you are testing GNOME 2.17,
send us your best screenshot. If you need ideas on what
to highlight, check out
the GNOME 2.18 release notes.
14GNOME 2.17.91 available for FreeBSD
Where have we been?! While we haven't been updating the
news page, we
have
been working on GNOME 2.17. We are pleased to announce
that GNOME 2.17.91 (aka GNOME 2.18 Beta 2) is now
available
along with glorious
packages.
We now request that all artistic people start submitting
their GNOME 2.17 screenshots for our gallery.
January31GNOME 2.16.3 available for FreeBSD
GNOME 2.16.3 was
released
and ports are available for FreeBSD. This is the final
release in the GNOME 2.16 series. The GNOME authors and
the FreeBSD GNOME Team have made sure that this release
rocks like none other. Packages will be a bit delayed for
2.16.3 as marcus is currently traveling. Expect packages
to start showing up in the
FreeBSD GNOME Tinderbox
on February 8th.
2006December21GNOME 2.17.4 available for FreeBSD
GNOME 2.17.4 was
released
just in time for Christmas. The one new module that is
currently showing up in the FreeBSD port is
Tracker.
As soon as the final set of new GNOME 2.18 modules is
ratified, they will be added to the various meta-ports.
Additionally, work has mostly been completed on a clean up
of the FreeBSD libgtop backend. This means that
applications like gnome-system-monitor will become much
more accurate on FreeBSD. As always,
ports
and
packages
are available to get you started with GNOME 2.17
testing.
6GNOME 2.17.3 available for FreeBSD
The third installment on the road to 2.18 has been
released
and we have cranked out the usual set of
ports
and
packages.
If you are one of the brave testers, please continue to
provide your feedback and
bug reports.
November29FreeBSD backend committed to HAL git
After seven months of development by Jean-Yves Lefort and
Joe Marcus Clarke in MarcusCom CVS, the FreeBSD backend
for
HAL
was finally
committed
upstream into the HAL git repository. This means that
future releases of HAL will have FreeBSD support
out-of-the-box. This is a major landmark in a project
that started on April 14, 2006 with the goal of bringing a
better desktop experience to FreeBSD users.
23GNOME 2.16.2 available for FreeBSD
GNOME 2.16 is maturing nicely with this
second
bug fix and optimization installment. Additionally,
thanks to our users, we have worked out quite a few bugs
in the new HAL implementation. Don't just stand there!
Upgrade already! Not a big fan of ports? Then try GNOME
2.16.2 from
packages.
14GNOME 2.17.2 available for FreeBSD
The follow-on release to GNOME 2.17.1 is a more complete
development snapshot. More of the new GNOME 2.18 features
are starting to show up. For instance, this release
features two new games: glchess and gnome-sudoku.
Ports
and
packages
are available for testing.
October22GNOME 2.17.1 available for FreeBSD
No rest for the weary. No sooner had we gotten 2.16.1
into ports that 2.17.1 was released. Being a .1 release,
this is still very rough, and only a few of the components
have been updated for the new development release.
However, we still encourage our local guinea
pigs...er...users to
try this out.
Not up for compiling this all yourself? That's cool, we
have
packages
pre-built with debugging symbols.
14GNOME 2.16.1 Unleashed!
GNOME 2.16.1 is now available for FreeBSD, and it is in
the ports tree in time for FreeBSD 6.2 (no you are NOT
dreaming)! This is a first. Usually the GNOME release
cycle has conflicted with the FreeBSD release cycle.
However, thanks to Kris and pointyhat, we were able to get
the major patch tested. In addition to the core GNOME
ports, almost 500 ports were also touched to chase the
GNOME move from X11BASE to LOCALBASE and fix build
problems with the new freetype2. The bulk of the move was
carried out by ahze, mezz, and pav, but it would not have
been possible without cooperation from the FreeBSD KDE
team who worked with us to make sure GNOME and KDE can
still coexist happily. We would also like to send a shout
out to kris and pointyhat for putting up with multiple
test runs until we got something that was solid.
Back to GNOME 2.16. This release brings a huge amount of
new functionality to FreeBSD. Check out the standard
release notes
to get the official spiel from the GNOME camp. But on top
of what you will read there, jylefort and marcus have
completed work on a port of HAL to FreeBSD. This will
allow FreeBSD to take advantage of closer hardware
interaction such as auto-mounting CD-ROMs, USB drives, and
music players; auto-playing audio CDs; and managing laptop
power consumption.
September17GNOME 2.16 available for FreeBSD!
Quite possibly the most functional GNOME release ever is
now available for FreeBSD. GNOME 2.16 features HAL support
for FreeBSD which allows FreeBSD users to take advantage
of automatic volume mounting, advanced power management,
and more. In addition, many performance improvements have
gone into GNOME, and the eye candy has definitely been
improved. Check out the full set of
release notes
for all of the new goodies.
Due to the fact that GNOME 2.16 will be the first GNOME
release for FreeBSD to live in LOCALBASE, and because we
are so close to the release of FreeBSD 6.2, GNOME 2.16
will not be committed to the ports tree until sometime in
November most likely. In the meantime,
ports
and
packages
are available from MarcusCom.
August2GNOME 2.14.3 available for FreeBSD
The last update (*sniff*) to GNOME 2.14 has been released
with a fresh
batch
of bug fixes and translation updates. The
package
build is just starting, but ports are ready. But if you
want some real fun, check out
GNOME 2.15.
July27GNOME 2.15.90 available for FreeBSD
GNOME 2.16 Beta 1 has been released into its new home on
FreeBSD: /usr/local (or LOCALBASE for l33t p0rters). The
migration to LOCALBASE was quite smooth, but some ports
still need adjustment. This latest development snapshot
has an updated 2.16 module list (less Tomboy), and
packages
for all supported versions of FreeBSD are ready. So what
are you waiting for!
15GNOME is moving!
...PREFIXes, that is. That's right, GNOME is leaving its
home in X11BASE, and joining KDE (and a lot of other
ports) in LOCALBASE. This is being done as part of an
effort to collapse into one third-party package PREFIX as
X11R6 is no longer as relevant as it used to be. All of
the work is happening in the
MarcusCom ports tree,
so expect GNOME 2.16 under /usr/local. The work is going
extremely well, and we expect to be fully moved and

While still a beta, this release looks pretty solid. One
of the biggest known issues is that the new GConf schema
layout leaves behind a lot of leftover files (see
#328623
for more details). This should be fixed by release time.
We are entering crunch time, so please report any and all
problems. Enjoy!

GNOME 2.12 Beta 2 is
upon us,
and
ports
are now ready for FreeBSD.
Packages
for amd64 and i386 are forthcoming. For this release, we
have introduced a new feature that "normalizes" the shared
library versions for many of the major GNOME 2 components.

shared library version bump which will help tremendously
with upgrades. Test like there's no tomorrow!

from our
development branch FAQ.
FreeBSD GNOME to drop FreeBSD 4.X support
Starting with GNOME 2.11, and continuing with the release
of 2.12 and beyond, the FreeBSD GNOME team will no longer
support the GNOME Desktop on FreeBSD 4.X. Some of
lower-level components will be supported, however.
FreeBSD 4.X lacks many of the features needed for a modern
desktop, and there are now two stable 5.X releases with
6.0 around the corner. If you haven't done so already,
now would be a good time to upgrade to 5.X or 6.0.
April18GNOME 2.10.1 available for FreeBSD
GNOME 2.10.1 has been released, and FreeBSD ports are
already to go. This release is primarily a bug fix and

unexpected build failure fallout, but work is underway to
correct the problems. All of the changes in GNOME 2.10.1
can be found in the combined
change log.

on our
Tinderbox.

with testing.
November24GNOME 2.9.1 available for FreeBSD
Although a bit late due to the 5.3 ports freeze, GNOME
2.9.1 has been brought to FreeBSD. This first 2.10
development release is not for the faint of heart. Due to
changes in Nautilus, components such as
gnome-control-center and nautilus-media will not work.
However, if you have a strong constitution, please
join us
in testing GNOME 2.9.

was released on October 26th, and FreeBSD ports have been
available
since then. Packages are also up on the

tree merge until after 5.3 is released.
September16GNOME 2.8.0 Released!
The GNOME 2.8.0 Desktop has been released, and the
FreeBSD ports are ready to go. However, bad timing has
struck once again, and GNOME 2.8 was released in the
middle of the 5.3-RELEASE ports freeze. Therefore, GNOME
2.8 ports will not make it into the FreeBSD ports tree
until after 5.3 is released. The good news is, this will
give the FreeBSD GNOME team more time to do quality
assurance so to give you the best upgrade experience
possible. If you just have to have the updates now, you
can get the GNOME 2.8 ports from our
development CVS server.
Packages for i386 will also be available soon from the
GNOME Tinderbox.
BSD# Project Formation
The BSD# Project has recently been formed on
Novell Forge
and is devoted to porting and maintaining the Mono .NET
framework from Ximian on FreeBSD. The Mono framework
consists of not only the Mono runtime environment and
compiler but the XSP webserver and Apache mod_mono for
handling ASP.NET applications, the IKVM Java virtual
machine for handling Java within the .NET framework, and
numerous data providers to access common library functions
in C# or integration with existing C libraries. The
project is currently in it's early stages but has recently
finished ports for all the latest Mono packages
distributed by Ximian. There is still much more work to
be done; from fixing threading issues in the runtime
environment, to wider testing of XSP and IKVM, to further
understanding the framework and how it all functions.
Those interested in Mono and the BSD# Project are asked to
visit the project's
homepage
and join the
mailing lists.
Mono .NET Framework Release 1.0.1
The BSD# Project is pleased to announce that the entire
Mono 1.0.1 .NET framework from Ximian has been ported for
FreeBSD and is ready for use. In addition to an updated
port of the Mono runtime, ports for all the latest library
bindings, XSP and Apache mod_mono for ASP.NET, and the
IKVM Java VM for .NET have been made. Please be aware
that due to changes in the latest Mono release and recent
changes to threading in the 5.X branch of FreeBSD, these
packages only work on 5.3-BETA versions and above. These
ports are not currently available in the standard FreeBSD
ports tree at the moment as they require wider testing but
the intent is for them to be there soon. Those interested
in Mono may use mono-merge script available from the
BSD# Project
to merge the project's ports tree with their own.

Thanks to work by
Marcel Moolenaar,
the GNOME desktop now builds on ia64. There are runtime
issues to be resolved, but this was expected. Most

7GNOME 2.3.3 desktop available for FreeBSD
The GNOME 2.3.3, "The Four Hounds", has been released and
ported to FreeBSD. Hearty adventurers should checkout the
``ports'' module per the instructions at
http://www.marcuscom.com:8080/cgi-bin/cvsweb.cgi,
and download the ``marcusmerge'' script to aid in the
upgrade.
May22GNOME 2.3.2 desktop available for FreeBSD
On time, and featuring gnopernicus, the FreeBSD GNOME
team presents the next GNOME 2.3 development snapshot, the
"Little Hero" release. Testers should checkout the
``ports'' module per the instructions at

15GNOME 2.3.1 desktop available for FreeBSD
It's a bit late, but here none the less. For those
willing to live on the edge, the next installment of the
GNOME 2.3 development snapshot, code named "Daddy Walrus,"
has been ported. This snapshot lacks three ports found in
the official GNOME distribution. They are gnopernicus,
gnome-speech, and gnome-system-tools. The latter is
missing because it does not fully work with FreeBSD, while
the two former components rely on festival, which is
broken on -CURRENT. To help out with the testing, check
out the ``ports'' module per the instructions at
http://www.marcuscom.com:8080/cgi-bin/cvsweb.cgi.
Be sure to download the ``marcusmerge'' script as well to

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.

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.

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 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

Aerospace Corporation we are taking advantage of these
features in a number of different ways. This talk

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.

Setting up a central syslog server.
If you are concerned about the security of your logs, use a dedicated machine and lock it down.
Keep clocks in sync.
You may need to change log rotation schedule in /etc/newsyslog.conf. You can rotate based in size and/or time. This can be as much a policy decision as a hardware decision.
On central log host, change syslogd flags to listen to network. Each BSD does this differently, so check the man pages. Also, check out the -n flag for busy environments.
Make sure host firewall allows syslog traffic through.
Be careful to limit syslog traffic to just the trusted network or hosts. FreeBSD man page refers to syslogd as a "remote disk filling service".
For heavy logging environments, it is important to have a dedicated network. A down syslogd server can create a lot of "ARP who-has" broadcasts.
Most network devices such as printers and commercial firewalls support sending to a central syslog server. Take a look at "Snare" for Windows hosts.
To send messages from a Unix host, specify the host name prepended with @ instead of a file for logging in /etc/syslog.conf. For example, change /var/log/xferlog to @loghost.mydomain.biz. You can also copy and edit the line to have it log to both a local file and a remote host.

Why I like the CLI:
Uses minimal resources. Less space, less memory, fewer dependencies.
Similar between Unix-like systems. GUI tools seem to change every week.
Remote management. SSH rocks.
Everything is text. Configs, devices, output. CLI is natural complement.
Pipes and scripts. One time is hard, a thousand times is easy.
Only need a few tools. Grep, sed, awk, vi, cron.
Text config files. Easy to version, share, and comment.
Requires reading skills instead of clicking skills.
Much faster when you know what you are doing.

Important when you don't trust the computer you are using, such as a library computer or internet kiosk.
Available by default in Free/Net/Open BSD.
FreeBSD uses OPIE, Net/Open use S/Key.
One time passwords are based on your pass phrase, a non-repeating sequence number, and a seed.
Initial setup should be done directly on the server.
"skeyinit" for Net/Open, "opiepasswd -c" for FreeBSD.
Enter a pass phrase that is not your regular account password.
Find your current sequence number and seed with "opieinfo" or "skeyinfo", for example: "497 pc5246".
Generate a list of the next 10 passwords and write them down, using "opiekey -n 10 497 pc5246" or "skey -n 10 497 pc5246".
When you log in from a remote machine that might have a keystroke logger, you can now use a one time password instead of your regular password.
For OpenBSD, log in as account:skey, for example "bob:skey", which will cause the system to present the s/key challenge.
For NetBSD, the system will always present you with the s/key challenge if it is configured for your account, although you can still use your regular password.
FreeBSD by default will force you to use a one time password if it is configured for your account.
If you want both OPIE and password authentication, FreeBSD allows you to list trusted networks or hosts in /etc/opieaccess.
Instead of carrying a list of passwords around, you can use s/key generators on a portable device that you trust, such as a palm pilot.
For more info, check the man pages.

A sneak peak into the FreeBSD development process.

(The schedule worked out was optimistic to say the
least but it's still looking ok...)
Marko Zec and Julian Elischer report back to the
developers at BSDCan on the progress on virtualizing
the network stack in FreeBSD. This has been a long
term project but at the time of this recording was
just reaching the point of feasibility. In this
video you can see some of the dynamics of the group
as developers become familiar with the project and
discussions take place regarding such things as
maintainability, ABI compatibility, and even what
to call the feature. In this video you can see the
decision being made by a "quorum" of developers to
take this project mainstream.
The sound is less that perfect, but it's what we have.
This is a montage of 3 video sources, one of which
is a lower resolution, but at times it was the only
camera capturing the action. (the other ran out of
tape for a while)
Thanks to Ed Maste for the added footage.
I will be doing more editing later and will be
substituting in better footage in some places.

In the past ten years most of the research in network
protocols has gone into TCP, leaving UDP to languish
as a local configuration protocol. While the majority
of Internet traffic is TCP, UDP remains the only
IP protocol that works over multicast and as such
has some specific, and interesting uses in some
areas of computing. In 2008 we undertook a study
of the performance of UDP multicast on both 1Gbps
and 10Gbps Ethernet networks in order to see if
changing the physical layer of the network would
give a linear decrease in packet latency. To measure
the possible gains we developed a new network
protocol test program, mctest, which is capable of
recording packet round trip times from many hosts
simultaneously and which we believe accurately
represents how many environments use multicast. The
mctest program has been integrated into FreeBSD and
is now being used to verify the proper operation
of multicast on various pieces of 10Gbps hardware.

In recent years, traditional branches of engineering
like Civil, Chemical, Mechanical, Electrical and
Industrial Engineering are requiring extensive
computing facilities for their needs. Several well
known labs (Sandia, Lawrence Livermore) rely on
huge clusters to do all types of complex analysis
that were unthinkable a couple of decades ago. While
the free BSD variants share the environment with
traditional UNIX systems, frequently used for such
computations, it was not common to find adequate
free software packages to carry complex calculations.
Eventually commercial versions of important math
related packages started to appear for the Linux
platform. Even when the big packages were distant,
the BSDs learned and adapted in resourceful ways:
Matlab and Mathematica, running under Linux emulation,
demanded functionality from the BSDs and NetBSD
implemented a signal trampoline to be able to run
AutoCAD with IRIX binary compatibility. A notable
project that was always available under a free
license was Berkeley's Spice circuit analysis
program, however it was an exception rather than
the rule. Even when the scientific community pressed
for a while to get other important tools like NASA's
FEA package Nastran under a free license, the
objective of being able to access and enhance open
scientific tools was elusive. About a decade ago
the situation started to improve: FreeBSD's ports
system started growing exponentially, first with a
high content in the math category, afterwards with
a CAD section and after sustained growth in those
categories a science section was created. This
growth was mostly pushed by Universities and their
research projects and in general are not well known
with respect to the commercial counterparts. I
started porting math/engineering code for FreeBSD
around 1996. Back then it was absolutely unthinkable
for a Mechanical Engineer to depend only on FreeBSD
for it's daily work. The situation nowadays is
different: there are some very high quality engineering
analysis packages like EDF's Code Aster, with more
than 12 years of professional development, that
just can't be ignored. A Finite Element package,
like Code Aster, can easily cost 5000 US$, is priced
according to the maximum problem size it can solve,
can require yearly licenses, and is rarely available
with source code. In NASTRAN's case the source code
is only available for US citizens under a yearly
fee. Free software does have serious limitations
though; just like in office applications there are
proprietary CAD formats or sometimes the package
simply doesn't have the required functionality.
Having the sources, of course, always has the
advantage of being able to implement (or pay for)
some specific functionality you might need. Many
commercial packages have been recently ported to
Linux, but even when they gain some of the advantages
of an open environment they still have yet another
limitation: they have been very slow to make use
of the multicored features of the new processors
in the market, a huge limitation now that the speed
war between processors has been limited by the
overheating problem. The objective of the talk is
to give an overview of several CAD/CAE packages
that have been made available recently as part of
FreeBSD's ports system and the decisions that were
made to port them. BRLCAD and Varkon are two CAD
utilities that made a transition from closed source
to an open environment and in the process in the
process of getting ported to BSD have gained greater
portability and general "bug" fixes critical for
their consolidation as usable and maintainable
projects. There are also some tricks that have not
been well documented: it is possible to enable
threads and some extra optimizations on some packages,
and it is also possible to replace the standard
BLAS library with the faster GOTO BLAS without
rebuilding the package. It is also possible to build
the packages optimized for a clustered environment,
but perhaps what is most interesting of all is how
all the packages interrelate with each other and
can turn FreeBSD into a complete enginering
environment. No OS distribution so far is offering
all the engineering specific utilities offered
through FreeBSD's ports system: from design to
visualization, passing through analysis FreeBSD is
becoming an option that can't be ignored, and best
of all, it is an effort that will benefit not only
FreeBSD but the wider audience.
Pedro F. Giffuni M. Sc. Industrial Engineering -
University of Pittsburgh Mechanical Engineer -
Universidad Nacional de Colombia I was born in
Bogota, Colombia but I am an Italian citizen. My
experience with computers started when I was about
12 years old With the TRS-80 Color Computer first
using Basic and the OS-9. I studied electronics for
3 years but became tired of worrying about "whatever
happened to electrons in there" and moved to
Mechanical Engineering. For a while I rested from
the computer world until the Internet came stepping
along. I started using FreeBSD around 1995 and soon
fell in love with the idea of being able to install
a complete version of UNIX from the net with just
one floppy. After submitting a the 999th port to
the FreeBSD project Walnut Creek was kind enough
to give me a subscription for several years to
FreeBSD's CD-ROM. Since then I've been on and off
porting software packages or fixing the bugs I have
caused while porting them. Of course there has
always been great respect for the other BSDs and
their wonderful license and while I've given up on
the idea of one day seeing a "UnifiedBSD" I am glad
to see different approaches sharing ideas in a
healthful environment.

In this talk, we will discuss the past and present
history and the design principles of the OpenBSD
hardware sensors framework. Sensors framework
provides a unified interface for storing, registering
and accessing information about hardware monitoring
sensors. Sensor types include, but are not limited
to, temperature, voltage, fan RPM, time offset and
logical drive status. The framework spans
sensor_attach(9), sysctl(3), sysctl(8), sensorsd(8),
ntpd(8), snmpd(8) and more than 67 drivers, ranging
from I2C temperature sensors and Super I/O hardware
monitors to IPMI, RAID and SCSI enclosures. Several
third-party tools are also available, for example,
a plug-in for Nagios and ports/sysutils/symon.

Martin Schuette has three main goals, defined by three
internet drafts to implement:
TLS transport is the most obvious improvement: it
provides a reliable network transport with data encryption
and peer authentication. To make full use of this a
buffering mechanism to bridge temporary network errors
is implemented as well.
Syslog-protocol extends the message format to use
a complete timestamp, include a fully qualified domain
name, and allow UTF-8 messages. It also offers a
structured data field to unambiguously encode application
dependent information.
Syslog-sign will allow any syslog sender to digitally
sign its messages, so their integrity can be verified
later. This enable the detection of loss, deletion or
other manipulation syslog data after network transfer
or archiving on storage media.
Martin Schuette is a student of computer science in
Potsdam, Germany, and has been working as a part-time
system administrator for BSD servers since 2004.
In 2007 Martin Schuette already gave a talk on Syslog
at the Chemnitze Linux-Tage

Given the modern trend towards multi-core shared
memory multiprocessors, it is inconceivable for
production OS kernels not to be reentrant. The
typical approach for allowing multiple execution
contexts to simultaneously execute in kernel mode
has been to use fine-grained locking for synchronising
access to shared resources. While this technique
has been proven efficient, empirical evidence
suggests that the resulting locking rules tend to
be cumbersome even for the experienced kernel
programmer, leading to bugs that are hard to diagnose.
Moreover, scaling to more processors requires
extensive use of locks, which may impose unnecessary
locking overhead for small scale multiprocessor
systems. This talk will describe the typical approach
and then discuss the alternative approach taken in
the DragonFlyBSD network stack. We will give an
overview of the various protocol threads employed
for network I/O processing and the common-case code
paths for packet reception and transmission.
Additionally, we'll need to make a passing reference
to DragonFlyBSD's message passing model. This should
establish a baseline, allowing us to focus on the
recent work by the author to eliminate use of the
Big Giant Lock in the performance-critical paths
for the TCP and UDP protocols. The decision to
constrain this work on the two by far most widely-used
transport protocols was made in order to (a) limit
the amount of work necessary and (b) explore the
effectiveness of the approach on the cases that
matter at this point in time.

Many BSD-licensed strategies of various levels of
maturity exist to implement multiplicity, herein
defined as the introduction of plurality to
traditionally singular computing environments via
isolation, virtualization, or other method. For
example, the chroot utility introduces an additional
isolated root execution environment within that of
the host; or an emulator provides highly-isolated
virtual systems that can run complete native or
foreign operating systems. Motivations for multiplicity
vary, but a demonstrable desire exists for users
to obtain root or run a foreign binary or operating
system. We propose a hands-on survey of portable
and integrated BSD-licensed multiplicity strategies
applicable to the FreeBSD, OpenBSD, DragonFlyBSD
and NetBSD operating systems on the i386 architecture.
We will also address three oft-coupled disciplines:
software storage devices, the installation of
operating system and userlands in multiplicity
environments plus the management of select multiplicity
environments. Finally we will comment on each
strategies potential limits of isolation, compatibility,
independence and potential overhead in comparison
to traditional systems. Keywords: multiplicity,
virtualization, chroot, jail, hypervisor, xen,
compat.
Michael Dexter has used Unix systems since 1991 and
BSD-licensed multiplicity strategies for over five
years. He is the Program Manager at the BSD Fund
and Project Manager of the BSD.lv Project.

Hello My name is Nick Barkas. I'm a master's student
studying scientific computing at Kungliga Tekniska
hgskolan (KTH) in Stockholm, Sweden. I have just
begun work on a Google Summer of Code project with
FreeBSD: Dynamic memory allocation for dirhash in
UFS2 . I would like to present my results from
this project at EuroBSDCon this year. This project
is very much a work in progress now so it is a bit
difficult to summarize what I would ultimately
present. I will try to describe an outline, though.
First I will give background information on dirhash:
an explanation of the directory data structure in
UFS2, how directory lookups in this structure
necessitate a linear search, and how dirhash speeds
these lookups up without having to change anything
about the directory data structure. Next I will
explain the current limitation that dirhash's maximum
memory use must be manually specified by administrators,
or left at a small conservative default of 2MB. I
will explain some different methods I will have
explored to try and make this maximum memory limit
dynamically increase and decrease as the system has
more or less free memory, and which method I will
have ultimately settled on and implemented. Then
I'll present some test results of performance of
operations on very large directories with and without
dynamic memory allocation enabled for dirhash. Next
I will talk about how speed gains from dirhash are
limited by the fact that the hash tables exist only
in memory and must be recreated after each system
boot, as big directories are scanned for the first
time, or even have to be recreated for a directory
that has not been scanned in some time if its dirhash
has been discarded to free memory. These problems
can be eliminated by using an on-disk index for
directory entries. I will talk about some of the
challenges of implementing on-disk indexing, such
as remaining backwards compatible with older versions
of UFS2 and interoperating properly with softupdates.
Then, if my SoC project has permitted me time to
work on this aspect of it, I will explain some
possible methods for adding directory indexing to
UFS2 that meets these challenges, and which of those
ideas I will have implemented. Finally I will present
results of some benchmarks on this filesystem with
indices, and compare to performance with dirhash,
and with no indices or dirhashes.
Keywords: dirhash, ufs2, filesystems, performance tuning

Traditional project management methodologies are
typically based on the waterfall model where there
are distinct phases: requirements capture, design,
implementation, testing, delivery. Once a project
has moved on to the next phase there is no going
back. The end result is often a late project that
no-one wants anymore because the requirements have
fundamentally changed by the time the project is
delivered.

The members of the BSD family have traditionally
prospered off the desktop, as operating systems on
servers and embedded systems. The advent of MacOS
X has marked a change, and moved the desktop more
into focus. Modern desktop systems create a richer
software landscape, with more diverse requirements,
than their server counterparts. User demands,
software package interdependencies and frequent
security issues result in a change rate that can
put a considerable load on the admin staff. Without
central management tools, previously identical
installations diverge quickly. This paper looks at
concepts and strategies for managing tens to hundreds
of modern, Unix-like desktop clients. The available
management tools range from simple, image-based
software distribution, mainly used for setting up
uniform clients, to "intelligent" rule-based engines
capable of search-and-replace operations on
configuration files. We will briefly compare their
properties and limitations, then take a closer look
at Radmind, a suite for file level administration
of Unix clients. Radmind has been in use in the
Institute of Telecommunication at Technische
Universitt Darmstadt for over three years, managing
NetBSD and Debian Linux clients in the labs as well
as faculty members' machines. We will explore the
Radmind suite's underlying concepts and functionality.
In order to see how the concept holds up, we will
discuss real-world scenarios from the system
life-cycle of Installation, configuration changes,
security updates, component updates, and system
upgrades.
Hauke Fath works as a systems administrator for the
Institut fr Nachrichtentechnik (telecommunication)
at Technische Universitt Darmstadt. He has been
using NetBSD since 1994, when he first booted a
NetBSD 1.0A kernel on a Macintosh SE/30. NetBSD
helped shaping his career by causing a slow drift
from application programmer's work towards systems
and network administration. Hauke Fath holds a MS
in Physics and became a NetBSD developer in late
2006.

This paper discusses the NetBSD Power Management
Framework (PMF) and related changes to the kernel.
The outlined changes allow NetBSD to support essential
functions like suspend-to-RAM on most post-Y2K X86
machines. They are also the fundation for intelligent
handling of device activity by enabling devices
on-demand. This work is still progressing. Many of
the features will be available in the up-coming
NetBSD 5.0 release The NetBSD kernel is widely
regarded to be one of the cleanest and most portable
Operating System kernels available. For various
reasons it is also assumed that NetBSD only runs
well on older hardware. In the summer of 2006 Charles
Hannum, one of the founders of NetBSD, left with a
long mail mentioning as important issues the lack
of proper power management and suspendto- RAM
support. One year later, Jared D. McNeill posted a
plan for attacking this issue based on ideas derived
from the Windows Driver Model. This plan would
evolve into the new NetBSD Power Management Framework
(PMF for short).

The Aerospace Corporation operates a federally
funded research and development center in support
of national-security, civil and commercial space
programs. Many of our 2400+ engineers use a variety
of computing technologies to support their work.
Applications range from small models which are
easily handled by desktops to parameter studies
involving thousands of cpu hours and traditional,
large scale parallel codes such as computational
fluid dynamics and molecular modeling applications.
Our primary resources used to support these large
applications are computing clusters. Our current
primary cluster, the Fellowship cluster consists
of 352 dual-processor nodes with a total of 14xx
cores. Two additional clusters, beginning at 150
dual-processor nodes each are being constructed to
augment Fellowship. As in In any multiuser computing
environment with limited resources, user competition
for resources is a significant burden. Users want
everything they need to do their job, right now.
Unfortunately, other users may need those resources
at the same time. Thus, systems to arbitrate this
resource contention are necessary. On Fellowship
we have deployed the Sun Grid Engine scheduler which
scheduled batch jobs across the nodes. In the next
section we discuss the performance problems that
can occur when sharing resources in a high performance
computing cluster. We then discuss range of
possibilities to address these problems. We then
explain the solutions we are investigating and
describe our experiments with them. We then conclude
with a discussion of future work.

The University of Toronto is a large educational
institutional with over 70,000 students and 10,000
staff and faculty. For the past three years, we
have developed and implemented a ubiquitous VPN
service, based up on OpenVPN and FreeBSD. The service
has over 3000 active customers, with up to 35
simultaneous users. The system supports, Linux, Mac
OS X and Windows XP/Vista/2000 clients. Tools have
been developed to create a central CA which enables
users to log in to a secure server and get their
customized client, certificates and configuration.
The NSIS installer is used to generate the customized
windows installers. Similar packages are generated
for the various Unix based clients. Additional
WWW/PHP based tools, have been developed to monitor
and log usage of the service, using standard graphs,
alarms for excessive use and a certificate revocation
mechanism. The system has been integrated into the
local identity management system (Kerberos/LDAP)
in order to authorize and authenticate users upon
initiation and per session usage. All code is Open
Source and freely available.

ABSD/UNIX operating system is traditionally split
into two pieces: the kernel and userspace. Historically
the reasons for this were clear: the UNIX kernel
was a simple entity. However, over time the kernel
has grown more and more complex. Currently, most
of the same functionality is available both in
userspace and the kernel, but under different names.
Examples include synchronization routines and
threading support. For instance, to lock a mutex
in the NetBSD kernel, the call is mutex_enter(),
while in userspace the routine which does exactly
the same thing is known as pthread_mutex_enter().
Taking another classic example, a BSD style OS has
malloc()/free() available both in userspace and the
kernel, but with different linkage (the kernel
malloc interface is currently being widely deprecated,
though). This imposes a completely arbitrary division
between the kernel and userspace. Most functionality
provided by an opearating system should be treated
as a service instead of explicitly pinning it down
as a userspace daemon or a kernel driver. Currently,
due to the arbitrarily difference in programming
interface names, functionality must be explicitly
ported between the kernel and userspace if it is
to run in one or the other environment. By unifying
the environments where possible, the arbitrary
division is weakened and porting between these
environments becomes simpler.
Antti Kantee has been a NetBSD developer for many
many moons. He has managed to work on quite a few
bits and pieces of a BSD system: userland utilities,
the pkgsrc packaging system, networking, virtual
memory, device drivers, hardware support and file
systems.

Robert Watson will describe the design and application
of the TrustedBSD MAC Framework, a flexible kernel
security framework developed on FreeBSD, and recently
experimentally ported to Apple's Darwin operating
system. The MAC Framework permits loadable access
control kernel modules to be loaded, modifying the
security behavior of the operating system, including
SEBSD, a port of the SELinux FLASK/TE security model
to FreeBSD.

OpenBSM is a BSD-licensed implementation of Sun's
Basic Security Module (BSM) API and file format,
and is the foundation of the TrustedBSD audit
implementation for FreeBSD. This talk will cover
the requirements, design, and implementation of
audit support for FreeBSD. Security audit support
provides detailed logging of security-relevant
events, and meets the requirements of the CAPP
Common Criteria protection profile.

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.

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.

the TrustedBSD MAC Framework, Audit facilities for
FreeBSD, as well as supporting infrastructure work
such as GEOM/GBDE, UFS2, OpenPAM. He will also

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.

pdfGlobal software development in the FreeBSD project
FreeBSD is a sophisticated operating system developed
and maintained as open-source software by a team
of more than 350 individuals located throughout the
world. This study uses developer location data, the
configuration management repository, and records
from the issue database to examine the extent of
global development and its effect on productivity,
quality, and developer cooperation. The key findings
are that global development allows round-the-clock
work, but there are some marked differences between
the type of work performed at different regions.
The effects of multiple dispersed developers on the
quality of code and productivity are negligible.
Mentoring appears to be sometimes associated with
developers living closer together, but ad-hoc
cooperation seems to work fine across continents.

skills in Unix system administration and system
programming. In 1990 moved to Lehman Brothers,
worked on system management tooling, and network
engineering. Ported "Moira" from MIT to Lehman,
built efficient build systems that predated (and
partly inspired) Jumpstart. In 1994 joined ESM to
market "CMDB" tools to enterprise users, but this
did not pan out, in the mean time learned Tcl, and
contributed bunch of patches to the 7.x early 8.x
TCL releases. In 1997 returned to New York, working
in IT Security at Morgan Stanley since late 1999.
At Morgan Stanley, developed a hobby in perimeter
email security, becoming an active Postfix user and
very soon contributor in May of 2001. In addition
to many smaller feature improvements, contributed
initial implementation of SMTP connection caching,
overhauled and currently maintain LDAP and TLS
support. Made significant design contributions to
queue manager in collaboration with Wietse and
Patrik Raq. In 2.6 contributing support for TLS EC
ciphers and multi-instance management tooling,
ideally also TLS SNI if time permits.

What it is and how can it make system administration
less painful
About the speaker:
Larry Ludwig - Principal Consultant/Founder of
Empowering Media. Empowering Media is a consulting
firm and managed hosting provider. Larry Ludwig
has been in the industry for over 15 years as a
system administration and system programmer. He's

Many modern CPUs provide on chip counters for
performance events such as retiring instructions
and cache misses. The hwpmc driver and libraries
in FreeBSD give systems administrators and programmers
access to APIs which make it possible to measure
performance without modifying source code and with
minimal intrusion into application execution. This
talk will be a brief introduction to HWPMC, and how
to use it.

Two tools which have become the norm in Linux- and
Unix-based environments are SSH for secure
communications, and sudo for performing administrative
tasks. These are independent programs with substantially
different purposes, but they are often used in
conjunction. In this talk, I describe a flaw in
their interaction, and then present our solution
called public-key sudo.
Public-key sudo is an extension to the sudo
authentication mechanism which allows for public
key authentication using the SSH public key framework.
I describe our implementation of a generic SSH
authentication module and the sudo modifications
required to use this module.

Configuration Management with Cfengine
Cfengine is a policy-based configuration management
system. Its primary function is to provide automated
configuration and maintenance of computers, from a
policy specification.
The cfengine project was started in 1993 as a
reaction to the complexity and non-portability of
shell scripting for Unix configuration management,
and continues today. The aim was to absorb frequently
used coding paradigms into a declarative, domain-specific
language that would offer self-documenting
configuration.
about the speaker:
Steven Kreuzer has been working with Open Source
technologies since as long as he can remember,
starting out with a 486 salvaged from a dumpster
behind his neighborhood computer store. In his spare
time he enjoys doing things with technology that
have absolutely no redeeming social value.
This talk is the result of an after-meeting discussion
with a few folks, when it became apparent that there
is some confusion as to how to deal with OpenBSD
in small and large environments. The topic of
installation and upgrading came up again. This talk
is aimed to hopefully dispel many of the rumors,
provide a thorough description and walk through of
the various stages of running OpenBSD in any size
environment, and some of the features and tools at
the administrator's disposal.
Okan Demirmen has been working with UNIX-like systems
for as long as he can remember and has found OpenBSD
to match some of the same philosophies in which he
believes, namely simplicity and correctness, and
reap the benefits of such.

Special NYC*BUG meeting with FreeBSD developer Brooks Davis
Since late 2000 we have developed and maintained a
general purpose technical and scientific computing
cluster running the FreeBSD operating system. In
that time we have grown from a cluster of 8 dual
Intel Pentium III systems to our current mix of 64
dual, quad-core Intel Xeon and 289 dual AMD Opteron
systems.
In this talk we reflect on the system architecture
as documented in our BSDCon 2003 paper "Building a
High-performance Computing Cluster Using FreeBSD"
and our changes since that time. After a brief
overview of the current cluster we revisit the
architectural decisions in that paper and reflect
on their long term success. We then discuss lessons
learned in the process. Finally, we conclude with
thoughts on future cluster expansion and designs.

Open Meeting on OpenSSH
Febrary's NYCBUG meeting is a broad look at OpenSSH,
the de facto method for remote administration and
more. OpenSSH celebrated its 8th anniversary this
past September, and we thought this would be a great
opportunity to discuss OpenSSH, and for others to
contribute their hacks and interesting applications.
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.

Cryptography has a reputation of slowing down
applications. However if done correctly, it can
actually be used to improve performance by storing
high-value/high-cost results "in public." In addition
the same techniques can solve common security
problems such as authorization, parameter scanning,
and parameter rewriting.
All are welcome - no previous experience with
cryptography is required, and the techniques will
be presented in a programming-language neutral
format.

"The Real Unix Tradition"
UNIX hackers, all standing on the shoulders of giants.
"...the number of UNIX installations has grown to
10, with more expected..." - Dennis Ritchie and Ken
Thompson, June 1972
"Well, it was all Open Source, before anybody really
called it that". - Brian Redman, 2003
UNIX is the oldest active and growing computing
culture alive today. From it's humble roots in the
back room at Bell Laboratories, to today's global
internet infrastructure- UNIX has consistently been
at the core of major advances in computing. Today,
the BSD legacy is the most direct continuation of
the most successful principles in UNIX, and continues
to lead major advances in computing.
Why? What's so great about UNIX?
This lecture aims to prove that UNIX history is
surprisingly useful (and fun)- for developers,
sysadmins, and anyone working with BSD systems.

This presentation was inspired by the recent
Subversion presentation. It will talk about the
origins of OpenRCS and OpenCVS, its real-world usage
in the OpenBSD project, and why OpenBSD will continue
to use CVS.
Ray is an OpenBSD developer who uses Subversion by
day, CVS by night. Taking the phrase "complexity
is the enemy of security" to heart, he believes
that the beauty of UNIX's security is in its
simplicity.
Security policies are a key component in protecting
enterprise networks. But, while there are many
diverse defensive options available, current models
and mechanisms for mechanically-enforced security
policies are limited to traditional admission-based
access control. Defensive capabilities include among
others logging, firewalls, honeypots, rollback/recovery,
and intrusion detection systems, while policy
enforcement is essentially limited to one-off access
control. Furthermore, access-control mechanisms
operate independently on each service, which can
(and often does) lead to inconsistent or incorrect
application of the intended system-wide policy. We
propose a new scheme for global security policies.
Every policy decision is made with near-global
knowledge, and re-evaluated as global knowledge
changes. Using a variety of actuators, we make the
full array of defensive capabilities available to
the global policy. Our goal is a coherent,
enterprise-wide response to any network threat.

The presentation will discuss Subversion from both
client and server points of view. It will show how
to create repositories and how to make them accessible
over the network using different access schemes
like http://, file:// or svn://. Pointers are given
on securing the repositories and on authenticating
and authorizing the clients. Next, the presentation
shows how an user interacts with the repository and
describes some of the important Subversion client
commands. Finally, it deals with administrating
the repository using "hook scripts".
Ivan Ivanov is generally interested in Version
Control Systems since his student years in Sofia
University, Bulgaria, where he set up and maintained
a CVS server for an academic project. When Subversion
became a fact and proved to be "a better CVS" he
researched it and last year deployed it for his
NYC-based employer Ariel Partners
(http://www.arielpartners.com/). He integrated the
Subversion repositories with Apache Web Server over
https to enable a reliable and secure way to access
them from any point.

UNIX professionals are busy these days. Setting up
routers and firewalls are fundamental to any network,
but in environments where the focus is on various
applications, (servers, workstations, and the
software that runs on them), it's difficult for a
business not to choose off-the-shelf SOHO routers
and networking gear. The web management GUIs are
understandable by everyone, (even techs without
UNIX knowledge), and the gear is cheap - this saves
time and money.
In the meantime, the features of your average Linksys
or Netgear router often leave MUCH to be desired,
(https auth management, for one simple example).
Enter m0n0wall and PFSense, 2 BSD based packaged
router/firewall solutions that are as solid and
full featured as you'd expect from any BSD system-
PLUS THEY HAVE HTML WEB INTERFACES FOR MANAGEMENT!
m0n0wall and PFSense become an easy sell in any
small professional environment, any competent tech
can manage the network within minutes... At home,
in every hackers home network, they free the hacker
to have trusted tools available, but are as time-saving
as using any Linksys router.
m0n0wall and PFSense are both light and clean,
designed to run on embedded systems- (Soekris,
WRAP), but are monsters when unleashed on even
legacy PCs around the office. If you manage UNIX
networks and systems all day, do you really want
to manage the router for your DSL when you get home?
But then doesn't it bug you to use a chincey Linksys
box?

Network Protocol Development Tools and Techniques for FreeBSD
Our Speaker:
George Neville-Neil, co-author of the "Design and
Implementation of the FreeBSD Operating System"
"daemon" book.
Our Topic:
While computers have gotten faster and more powerful
the tools we use to develop network protocols, such
as TCP, UDP, IPv4 and IPv6 have not. Most network
protocols are developed, in C, in the kernel, and
require a lot of work to test. Over the past year
or so I have been working with virtual machines, a
couple of pieces of open source software, and begun
developing a library for use in protocol testing.
This talk will cover three topics:
Developing and testing kernel code with Virtual Machines
Finding good tests for networking code
Packet Construction Set (PCS) a new library for
writing protocol tests

We talk with Daniel Seuffert about BSD. Several
flavours of BSD were represented in a joint BSD
booth: OpenBSD, FreeBSD, NetBSD and MirOS. Daniel
is representative of the FreeBSD project and among
other things talks about the different operating
systems that are build on top of FreeBSD. For
instance, there are two distributions called PC-BSD
and DesktopBSD that are targeted towards desktop
users. There also is a version that specializes on
security entitled TrustedBSD.

COMPLETE Hard Disk Encryption with FreeBSD, by Marc Schiesser
Learn how to effectively protect not only your data
but also your applications.
Most technologies and techniques intended for
securing digital data focus on protection while the
machine is turned on mostly by defending against
remote attacks. An attacker with physical access
to the machine, however, can easily circumvent these
defenses by reading out the contents of the storage
medium on a different, fully accessible system or
even compromise program code on it in order to leak
encrypted information. Especially for mobile users,
that threat is real. And for those carrying around
sensitive data, the risk is most likely high. This
talk will introduce a method of mitigating that
particular risk by protecting not only the data
through encryption, but also the applications and
the operating system from being compromised while
the machine is turned off.

This is an extra track by the artist Ty Semaka (who
really has "had Puffy on his mind") which we included
on the audio CD.
This song details the process that Ty has to go
through to make the art and music for each OpenBSD

bar and discuss what is going on in the project,
and then try to find a theme that will work...

Nearly 10 years ago Kirk McKusick wrote a history
of the Berkeley Unix distributions for the O'Reilly
book "Open Sources: Voices from the Open Source
Revolution". We recommend you read his story,
entitled "Twenty Years of Berkeley Unix From
AT&T-Owned to Freely Redistributable" first, to see
how Kirk remembers how we got here. Sadly, since
it showed up in book form originally, this text has
probably not been read by enough people.
The USL(AT&T) vs BSDI/UCB court case settlement
documents were not public until recently; their
disclosure has made the facts more clear. But the
story of how three people decided to free the BSD
codebase of corporate pollution -- and release it
freely -- is more interesting than the lawsuit which
followed. Sure, a stupid lawsuit happened which
hindered the acceptance of the BSD code during a
critical period. But how did a bunch of guys go
through the effort of replacing so much AT&T code
in the first place? After all, companies had lots
of really evil lawyers back then too -- were they
not afraid?
After a decade of development, most of the AT&T
code had already been replaced by university
researchers and their associates. So Keith Bostic,
Mike Karels and Kirk McKusick (the main UCB CSRG
group) started going through the 4.3BSD codebase
to cleanse the rest. Keith, in particular, built a
ragtag team (in those days, USENIX conferences were
a gold mine for such team building) and led these
rebels to rewrite and replace all the Imperial AT&T
code, piece by piece, starting with the libraries
and userland programs. Anyone who helped only got
credit as a Contributor -- people like Chris Torek
and a cast of .. hundreds more.
Then Mike and Kirk purified the kernel. After a bit
more careful checking, this led to the release of
a clean tree called Net/2 which was given to the
world in June 1991 -- the largest dump of free
source code the world had ever received (for those
days -- not modern monsters like OpenOffice).
Some of these ragtags formed a company (BSDi) to
sell a production system based on this free code
base, and a year later Unix System Laboratories
(basically AT&T) sued BSDi and UCB. Eventually
AT&T lost and after a few trifling fixes (described
in the lawsuit documents) the codebase was free. A
few newer developments (and more free code) were
added, and released in June 1994 as 4.4BSD-Lite.
Just over 14 years later OpenBSD is releasing its
own 4.4 release (and for a lot less than $1000 per
copy).
The OpenBSD 4.4 release is dedicated to Keith Bostic,
Mike Karels, Kirk McKusick, and all of those who
contributed to making Net/2 and 4.4BSD-Lite free.

We are just plain tired of being lectured to by a
man who is a lot like Naomi Campbell.
In 1998 when a United Airlines plane was waiting
in the queue at Washington Dulles International
Airport for take-off to New Orleans (where a Usenix
conference was taking place), one man stood up from
his seat, demanded that they stop waiting in the
queue and be permitted to deplane. Even after orders
from the crew and a pilot from the cockpit he refused
to sit down. The plane exited the queue and returned
to the airport gangway. Security personnel ran onto
the plane and removed this man, Richard Stallman,
from the plane. After Richard was removed from the
plane, everyone else stayed onboard and continued
their journey to New Orleans. A few OpenBSD developers
were on that same plane, seated very closeby, so
we have an accurate story of the events.
This is the man who presumes that he should preach
to us about morality, freedom, and what is best for
us. He believes it is his God-given role to tell
us what is best for us, when he has shown that he
takes actions which are not best for everyone. He
prefers actions which he thinks are best for him
-- and him alone -- and then lies to the public.
Richard Stallman is no Spock.
We release our software in ways that are maximally
free. We remove all restrictions on use and
distribution, but leave a requirement to be known
as the authors. We follow a pattern of free source
code distribution that started in the mid-1980's
in Berkeley, from before Richard Stallman had any
powerful influence which he could use so falsely.
We have a development sub-tree called "ports". Our
"ports" tree builds software that is 'found on the
net' into packages that OpenBSD users can use more
easily. A scaffold of Makefiles and scripts
automatically fetch these pieces of software, apply
patches as required by OpenBSD, and then build them
into nice neat little tarballs. This is provided
as a convenience for users. The ports tree is
maintained by OpenBSD entirely separately from our
main source tree. Some of the software which is
fetched and compiled is not as free as we would
like, but what can we do. All the other operating
system projects make exactly the same decision, and
provide these same conveniences to their users.
Richard felt that this "ports tree" of ours made
OpenBSD non-free. He came to our mailing lists and
lectured to us specifically, yet he said nothing
to the many other vendors who do the same; many of
them donate to the FSF and perhaps that has something
to do with it. Meanwhile, Richard has personally
made sure that all the official GNU software --
including Emacs -- compiles and runs on Windows.
That man is a false leader. He is a hypocrite. There
may be some people who listen to him. But we don't
listen to people who do not follow their own stupid
rules.
Those of us who work on OpenBSD are often asked why
we do what we do. This song's lyrics express the
core motivations and goals which have remained
unchanged over the years - secure, free, reliable
software, that can be shared with anyone. Many other
projects purport to share these same goals, and
love to wrap themselves in a banner of "Open Source"
and "Free Software". Given how many projects there
are one would think it might be easy to stick to
those goals, but it doesn't seem to work out that
way. A variety of desires drag many projects away
from the ideals very quickly.
Much of any operating system's usability depends
on device support, and there are some very tempting
alternative ways to support devices available to
those who will surrender their moral code. A project
could compromise by entering into NDA agreements
with vendors, or including binary objects in the
operating system for which no source code exists,
or tying their users down with contract terms hidden
inside copyright notices. All of these choices
surrender some subset of the ideals, and we simply
will not do this. Sure, we care about getting devices
working, but not at the expense of our original
goals.
Of course since "free to share with anyone" is part
of our goals, we've been at the forefront of many
licensing and NDA issues, resulting in a good number
of successes. This success had led to much recognition
for the advancement of Free Software causes, but
has also led to other issues.
We fully admit that some BSD licensed software has
been taken and used by many commercial entities,
but contributions come back more often than people
seem to know, and when they do, they're always still
properly attributed to the original authors, and
given back in the same spirit that they were given
in the first place.
That's the best we can expect from companies. After
all, we make our stuff so free so that everyone can
benefit -- it remains a core goal; we really have
not strayed at all in 10 years. But we can expect
more from projects who talk about sharing -- such
as the various Linux projects.
Now rather than seeing us as friends who can
cooperatively improve all codebases, we are seen
as foes who oppose the GPL. The participants of
"the race" are being manipulated by the FSF and
their legal arm, the SFLC, for the FSF's aims,
rather than the goal of getting good source into
Linux (and all other code bases). We don't want
this to come off as some conspiracy theory, but we
simply urge those developers caution -- they should
ensure that the path they are being shown by those
who have positioned themselves as leaders is still
true. Run for yourself, not for their agenda.
The Race is there to be run, for ourselves, not for
others. We do what we do to run our own race, and
finish it the best we can. We don't rush off at
every distraction, or worry how this will affect
our image. We are here to have fun doing right.

As developers of a free operating system, one of
our prime responsibilities is device support. No
matter how nice an operating system is, it remains
useless and unusable without solid support for a
wide percentage of the hardware that is available
on the market. It is therefore rather unsurprising
that more than half of our efforts focus on various
aspects relating to device support.
Most parts of the operating system (from low kernel,
through to libraries, all the way up to X, and then
even to applications) use fairly obvious interface
layers, where the "communication protocols" or
"argument passing" mechanisms (ie. APIs) can be
understood by any developer who takes the time to
read the free code. Device drivers pose an additional
and significant challenge though: because many
vendors refuse to document the exact behavior of
their devices. The devices are black boxes. And
often they are surprisingly weird, or even buggy.
When vendor documentation does not exist, the
development process can become extremely hairy.
Groups of developers have found themselves focused
for months at a time, figuring out the most simple
steps, simply because the hardware is a complete
mystery. Access to documentation can ease these
difficulties rapidly. However, getting access to
the chip documentation from vendors is ... almost
always a negotiation. If we had open access to
documentation, anyone would be able to see how
simple all these devices actually are, and device
driver development would flourish (and not just in
OpenBSD, either).
When we proceed into negotiations with vendors,
asking for documentation, our position is often
weak. One would assume that the modern market is
fair, and that selling chips would be the primary
focus of these vendors. But unfortunately a number
of behemoth software vendors have spent the last
10 or 20 years building political
hurdles against the smaller players.
A particularly nasty player in this regard has been
the Linux vendors and some Linux developers, who
have played along with an American corporate model
of requiring NDAs for chip documentation. This has
effectively put Linux into the club with Microsoft,
but has left all the other operating system communities
-- and their developers -- with much less available
clout for requesting documentation. In a more fair
world, the Linux vendors would work with us, and
the device driver support in all free operating
systems would be fantastic by now.
We only ask that users
help us in changing the political landscape.
The last 10 years, every 6 month period has (without
fail) resulted in an official OpenBSD release making
it to the FTP servers. But CDs are also manufactured,
which the project sells to continue our development
goals.
While tests of the release binaries are done by
developers around the world, Theo and some developers
from Calgary or Edmonton (such as Peter Valchev or
Bob Beck) test that the discs are full of (only)
correct code. Ty Semaka works for approximately two
months to design and draw artwork that will fit the
designated theme, and coordinates with his music
buddies to write and record a song that also matches
the theme.
Then the discs and all the artwork gets delivered
to the plant, so that they can be pressed in time
for an official release date.
This release, instead of bemoaning vendors or
organizations that try to make our task of writing
free software more difficult, we instead celebrate
the 10 years that we have been given (so far) to
write free software, express our themes in art, and
the 5 years that we have made music with a group
of talented musicians.
OpenBSD developers have been torturing each other
for years now with Humppa-style music, so this
release our users get a taste of this too. Sometimes
at hackathons you will hear the same songs being
played on multiple laptops, out of sync. It is under
such duress that much of our code gets written.
We feel like Pufferix and Bobilix delivering The
Three Discs of Freedom to those who want them
whenever the need arises, then returning to celebrate
the (unlocked) source tree with all the other
developers.

pfSense: 2.0 and beyond
From firewall distribution to appliance building platform
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 will start with an introduction to the
project and its common uses, which have expanded
considerably beyond firewalling. We will cover much
of the new functionality coming in the 2.0 release,
which contains significant enhancements to nearly
every portion of the system as well as numerous new
features.
While the primary function of the project is a
firewalling and routing platform, with changes
coming in pfSense 2.0, it has also become an appliance
building framework enabling the creation of customized
special purpose appliances. The m0n0wall code where
pfSense originated has proved popular for this
purpose, with AskoziaPBX and FreeNAS also based
upon it, in addition to a number of commercial
solutions. The goal of this appliance building
framework is to enable creation of projects such
as these without having to fork and maintain another
code base. The existing appliances, including a DNS
server using TinyDNS, VoIP with FreeSWITCH, and
others will be discussed. For those interested in
creating appliances, an overview of the process
will be provided along with references for additional

GEOM based disk schedulers for FreeBSD
The high cost of seek operations makes the throughput
of disk devices very sensitive to the offered
workload. A disk scheduler can then help reorder
requests to improve the overall throughput of the
device, or improve the service guarantees for
individual users, or both.
Research results in recent years have introduced,
and proven the effectiveness of, a technique called
"anticipatory scheduling". The basic idea behind
this technique is that, in some cases, requests
that cause a seek should not be served immediately;
instead, the scheduler should wait for a short
period of time in case other requests arrive that
do not require a seek to be served. With many common
workloads, dominated by sequential synchronous
requests, the potential loss of throughput caused
by the disk idling times is more than balanced by
the overall reduction of seeks.
While a fair amount of research on disk scheduling
has been conducted on FreeBSD, the results were
never integrated in the OS, perhaps because the
various prototype implementations were very
device-specific and operated within the device
drivers. Ironically, anticipatory schedulers are
instead a standard part of Linux kernels.
This talk has two major contributions:
First, we will show how, thanks to the flexibility
of the GEOM architecture, an anticipatory disk
scheduling framework has been implemented in FreeBSD
with little or no modification to a GENERIC kernel.
While these schedulers operate slightly above the
layer where one would naturally put a scheduler,
they can still achieve substantial performance
improvements over the standard disk scheduler; in
particular, even the simplest anticipatory schedulers
can prevent the complete trashing of the disk
performance that often occurs in presence of multiple
processes accessing the disk.
Secondly, we will discuss how the basic anticipatory
scheduling technique can be used not only to improve
the overall throughput of the disk, but also to
give service guarantees to individual disk clients,
a feature that is extremely important in practice
e.g., when serving applications with pseudo-real-time
constraints such as audio or video streaming ones.
A prototype implementation of the scheduler that
will be covered in the presentation is available
at http://info.iet.unipi.it/~luigi/FreeBSD/

Quiet Computing with BSD
Programming system hardware monitors for quiet computing
In this talk, we will present a detailed overview
of the features and common problems of microprocessor
system hardware monitors as they relate to the topic
of silent computing. In a nutshell, the topic of
programmable fan control will be explored.
Silent computing is an important subject as its
practice reduces the amount of unnecessary stress
and improves the motivation of the workforce, at
home and in the office.
Attendees will gain knowledge on how to effectively
programme the chips to minimise fan noise and avoid
system failure or shutdown during temperature
fluctuations, as well as some basic principles
regarding quiet computing.
Shortly before the talk, a patch for programming
the most popular chips (like those from Winbond)
will be released for the OpenBSD operating system,
although the talk itself will be more specific to
the microprocessor system hardware monitors themselves,
as opposed to the interfacing with thereof in modern
operating systems like OpenBSD, NetBSD, DragonFly
BSD and FreeBSD.

Results of a Security Assessment of the TCP and IP
protocols and Common implementation Strategies
Fernando Gont will present the results of security
assessment of the TCP and IP protocols carried out
on behalf of the United Kingdom's Centre for the
Protection of National Infrastructure (Centre for
the Protection of National Infrastructure). His
presentation will provide an overview of the
aforementioned project, and will describe some of
the new insights that were gained as a result of
this project. Additionally, it will provide an
overview of the state of affairs of the different
TCP/IP implementations found in BSD operating systems
with respect to the aforementioned issues.
During the last twenty years, many vulnerabilities
have been identified in the TCP/IP stacks of a
number of systems. The discovery of these vulnerabilities
led in most cases to reports being published by a
number of CSIRTs and vendors, which helped to raise
awareness about the threats and the best possible
mitigations known at the time the reports were
published. For some reason, much of the effort of
the security community on the Internet protocols
did not result in official documents (RFCs) being
issued by the organization in charge of the
standardization of the communication protocols in
use by the Internet: the Internet Engineering Task
Force (IETF). This basically led to a situation in
which "known" security problems have not always
been addressed by all vendors. In addition, in many
cases vendors have implemented quick "fixes" to the
identified vulnerabilities without a careful analysis
of their effectiveness and their impact on
interoperability. As a result, producing a secure
TCP/IP implementation nowadays is a very difficult
task, in large part because of the hard task of
identifying relevant documentation and differentiating
between that which provides correct advisory, and
that which provides misleading advisory based on
inaccurate or wrong assumptions. During 2006, the
United Kingdom's Centre for the Protection of
National Infrastructure embarked itself in an
ambitious and arduous project: performing a security
assessment of the TCP and IP protocols. The project
did not limit itself to an analysis of the relevant
IETF specifications, but also included an analysis
of common implementation strategies found in the
most popular TCP and IP implementations. The result
of the project was a set of documents which identifies
possible threats for the TCP and IP protocols and,
where possible, proposes counter-measures to mitigate
the identified threats. This presentation will will
describe some of the new insights that were gained
as a result of this project. Additionally, it will
provide an overview of the state of affairs of the
different TCP/IP implementations found in BSD
operating systems.

Multiple Passes of the FreeBSD Device Tree
The existing device driver framework in FreeBSD
works fairly well for many tasks. However, there
are a few problems that are not easily solved with
the current design. These problems include having
"real" device drivers for low-level hardware such
as clocks and interrupt controllers, proper resource
discovery and management, and allowing most drivers
to always probe and attach in an environment where
interrupts are enabled. I propose extending the
device driver framework to support multiple passes
over the device tree during boot. This would allow
certain classes of drivers to be attached earlier
and perform boot-time setup before other drivers
are probed and attached. This in turn can be used
to develop solutions to the earlier list of problems.

scrypt: A new key derivation function
Doing our best to thwart TLAs armed with ASICs
Password-based key derivation functions are used
for two primary purposes: First, to hash passwords
so that an attacker who gains access to a password
file does not immediately possess the passwords
contained therewithin; and second, to generate
cryptographic keys to be used for encrypting or
authenticating data.
In both cases, if passwords do not have sufficient
entropy, an attacker with the relevant data can
perform a brute force attack, hashing potential
passwords repeatedly until the correct key is found.
While commonly used key derivation functions, such
as Kamp's iterated MD5, Provos and Mazieres' bcrypt,
and RSA Laboratories' PBKDF1 and PBKDF2 make an
attempt to increase the difficulty of brute-force
attacks, they all require very little memory, making
them ideally suited to attack by custom hardware.
In this talk, I will introduce the concepts of
memory-hard and sequential memory-hard functions,
and argue that key derivation functions should be
sequential memory-hard. I will present a key
derivation function which, subject to common
assumptions about cryptographic hash functions, is
provably sequential memory-hard, and a variation
which appears to be stronger (but not provably so).
Finally, I will provide some estimates of the cost
of performing brute force attacks on a variety of
password strengths and key derivation functions.

Tracking FreeBSD in a commercial Environment
How to stay current while staying sane
The FreeBSD project publishes two lines of source
code: current and stable. All changes must first
be committed to current and then are merged into
stable. Commercial organizations wishing to use
FreeBSD in their products must be aware of this
policy. Four different strategies have developed
for tracking FreeBSD over time. A company can choose
to run only unmodified release versions of FreeBSD.
A company may choose to import FreeBSD's sources
once and then never merge newer versions. A company
can choose to import each new stable branch as it
is created, adding its own changes to that branch,
as well as integrating new versions from FreeBSD
from time to time. A company can track FreeBSD's
current branch, adding to it their changes as well
as newer FreeBSD changes. Which method a company
chooses depends on the needs of the company. These
methods are explored in detail, and their advantages
and disadvantages are discussed. Tracking FreeBSD's
ports and packages is not discussed.
Companies building products based upon FreeBSD have
many choices in how to use the projects sources and
binaries. The choices range from using unmodified
binaries from FreeBSD's releases, to tracking modify
FreeBSD heavily and tracking FreeBSD's evolution
in a merged tree. Some companies may only need to
maintain a stable version of FreeBSD with more bug
fixes or customizations than the FreeBSD project
wishes to place in that branch. Some companies also
wish to contribute some subset of their changes
back to the FreeBSD project.
FreeBSD provides an excellent base technology with
which to base products. It is a proven leader in
performance, reliability and scalability. The
technology also offers a very business friendly
license that allows companies to pick and choose
which changes they wish to contribute to the community
rather than forcing all changes to be contributed
back, or attaching other undesirable license
conditions to the code.
However, the FreeBSD project does not focus on
integration of its technology into customized
commercial products. Instead, the project focuses
on producing a good, reliable, fast and scalable
operating system and associated packages. The project
maintains two lines of development. A current branch,
where the main development of the project takes
place, and a stable branch which is managed for
stability and reliability. While the project maintains
documentation on the system, including its development
model, relatively little guidance has been given
to companies in how to integrate FreeBSD into their
products with a minimum of trouble.
Developing a sensible strategy to deal with both
these portions of FreeBSD requires careful planning
and analysis. FreeBSD's lack of guidelines to
companies leaves it up to them to develop a strategy.
FreeBSD's development model differs from some of
the other Free and Open Source projects. People
familiar with those systems often discover that
methods that were well suited to them may not work
as well with FreeBSD's development model. These two
issues cause many companies to make poor decisions
without understanding the problems that lie in their
future.
Very little formal guidance exists for companies
wishing to integrate FreeBSD into their products.
Some email threads can be located via a Google
search that could help companies, but many of them
are full of contradictory information, and it is
very disorganized. While the information about the
FreeBSD development process is in the FreeBSD
handbook, the implications of that process for
companies integrating FreeBSD into their products
are not discussed.

PC-BSD - Making FreeBSD on the desktop a reality
FreeBSD on the Desktop
While FreeBSD is a all-around great operating system,
it is greatly lagging behind in desktop appeal. Why
is this? In this talk, we will take a look at some
of the desktop drawbacks of FreeBSD, and how are
are attempting to fix them through PC-BSD.
FreeBSD has a reputation for its rock-solid
reliability, and top-notch performance in the server
world, but is noticeably absent when it comes to
the vast market of desktop computing. Why is this?
FreeBSD offers many, if not almost all of the same
open-source packages and software that can be found
in the more popular Linux desktop distributions,
yet even with the speed and reliability FreeBSD
offers, a relative few number of users are deploying
it on their desktops.
In this presentation we will take a look at some
of the reasons why FreeBSD has not been as widely
adopted in the desktop market as it has on the
server side. Several of the desktop weaknesses of
FreeBSD will be shown, along with how we are trying
to fix these short-comings through a desktop-centric
version of FreeBSD, known as PC-BSD. We will also
take a look at the package management system employed
by all open-source operating systems alike, and
some of the pitfalls it brings, which may hinder
widespread desktop adoption.

Implementation of TARGET_MODE applications
How we used TARGET_MODE in the kernel to create and
interesting product
This presentation will cover a real world implementation
of the TARGET_MODE infrastructure in the kernel
(stable/6). Topics to include: drivers used (isp,
aic7xxx, firewire). scsi_target userland code vs
kernel drivers missing drivers (4/8G isp support,
iSCSI target)
Target Mode describes a feature within certain
drivers that allows a FreeBSD system to emulate a
Target in the SCSI sense of the word. By recompiling
your kernel with this feature enabled, it permits
one to turn a FreeBSD system into an external hard
disk. This feature of the FreeBSD kernel provides
many interesting implementations and is highly
desirable to many organizations whom run FreeBSD
as their platform.
I have been tasked with the maintenance of a
proprietary target driver that interfaces with the
FreeBSD kernel to do offsite data mirroring at the
block level. This talk will discuss the implementation
of that kernel mode driver and the process my
employer went through to implement a robust and
flexible appliance.
Since I took over the implementation, we have
implemented U160 SCSI(via aic7xxx), 2G Fibre
Channel(via isp) and Firewire 400 (via sbp_targ).
Each driver has it's own subtleties and requirements.
I personally enhanced the existing Firewire target
driver and was able to get some interesting results.
I hope to demonstrate a functional Firewire 400/800
target and show how useful this application can be
for the embedded space. Also, I wish to demonstrate
the need for iSCSI. USB and 4/8G Fibre Channel
target implementations that use the TARGET_MODE
infrastructure that is currently in place to allow
others to expand their various interface types.
The presentation should consist of a high level
overview, followed by detailed implementation
instructions with regards to the Firewire implementation
and finish up with a hands-on demonstration with a
FreeBSD PC flipped into TARGET_MODE and a Mac.

Understanding and Tuning SCHED_ULE
With the advent of widespread SMP and multicore CPU
architectures it was necessary to implement a new
scheduler in the FreeBSD operating system. The
SCHEDULE scheduler was added for the 5 series of
FreeBSD releases and has now matured to the point
where it is the default scheduler in the 7.1 release.
While scheduling processes was a difficult enough
task in the uniprocessor world, moving to multiple
processors, and multiple cores, has significantly
increased the number of problems that await engineers
who wish to squeeze every last ounce of performance
out of their system. This talk will cover the basic
design of SCHEDULE and focus a great deal of attention
on how to tune the scheduler for different workloads,
using the sysctl interfaces that have been provided
for that purpose.
Understanding and tuning a scheduler used to be
done only by operating systems designers and perhaps
a small minority of engineers focusing on esoteric
high performance systems. With the advent of
widespread multi-processor and multi-core architectures
it has become necessary for more users and
administrators to decide how to tune their systems
for the best performance. The SCHEDULE scheduler
in FreeBSD provides a set of sysctl interfaces for
tuning the scheduler at run time, but in order to
use these interfaces effectively the scheduling
process must first be understood. This presentation
will give an overview of how SCHEDULE works and
then will show several examples of tuning the system
with the interfaces provided.
The goal of modifying the scheduler's parameters
is to change the overall performance of programs
on the system. One of the first problems presented
to the person who wants to tune the scheduler is
how to measure the effects of their changes. Simply
tweaking the parameters and hoping that that will
help is not going to lead to good results. In our
recent experiments we have used the top(1) program
to measure our results.

Journaling FFS with WAPBL
NetBSD 5 is the first NetBSD release with a journaling
filesystem. This lecture introduces the structure
of the Fast File System, the modifications for WAPBL
and specific constraints of the implementation.
The Fast File System (FFS) has been used in the BSD
land for more than two decades. The original
implementation offered two operational modes:
safe and slow (sync)
unsafe and fast (async) One decade ago, Kirk
McKusick introduced the soft dependency mechanism
to offset the performance impact without risk of
mortal peril on the first crash. With the advent
of Terabyte hard disks, the need for a file system
check (fsck) after a crash becomes finally unacceptable.
Even a background fsck like supported on FreeBSD
consumes lots of CPU time and IO bandwidth.
Based on a donation from Wasabi Systems, Write Ahead
Physical Block Logging (WAPBL) provides journaling
for FFS with similar or better performance than
soft dependencies during normal operation. Recovery
time after crashes depends on the amount of outstanding
IO operations and normally takes a few seconds.
This lecture gives a short overview of FFS and the
consistency constraints for meta data updates. It
introduces the WAPBL changes, both in terms of the
on-disk format and the implementation in NetBSD.
Finally the implementation is compared to the design
of comparable file systems and specific issues of
and plans for the current implementation are
discussed.

Remote and mass management of systems with finstall
Automated management on a largish scale
An important part of the "finstall" project, created
as a graphical installer for FreeBSD, is a configuration
server that can be used to remotely administer and
configure arbitrary systems. It allows for remote
scripting of administration tasks and is flexible
enough to support complete reconfiguration of running
systems.
The finstall project has two major parts - the
front-end and the back-end. The front-end is just
a GUI allowing the users to install the system in
a convenient way. The back-end is a network-enabled
XML-RPC server that is used by the front-end to
perform its tasks. It can be used as a stand-alone
configuration daemon. This talk will describe a way
to make use of this property of finstall to remotely
manage large groups of systems.
Determining if a TCP stack is working correctly is
hard. The tcpdiff project aims for a simpler goal:
To automatically detect differences in TCP behavior
between different versions of an operating system
and display those differences in an easy to understand
format. The value judgement of whether a certain
change between version X and Y of a TCP stack is
good or bad will be left to human eyes.

bugs can be detected. Additionally, I plan to run
it on OSes other than FreeBSD.

Crypto Acceleration on FreeBSD
As more and more services on the internet become
cryptographically secured, the load of cryptography
on systems becomes heavier and heavier. Crypto
acceleration hardware is available in different
forms for different workloads. Embedded communications
processors from VIA and AMD have limited acceleration
facilities in silicon and various manufacturers
build hardware for accelerating secure web traffic
and IPSEC VPN tunnels.
This talk gives an overview of FreeBSD's crypto
framework in the kernel and how it can be used
together with OpenSSL to leverage acceleration
hardware. Some numbers will be presented to demonstrate
how acceleration can improve performance - and how
it can curiously bring a system to a grinding halt.
Philip originally started playing with crypto
acceleration when he saw the "crypto block" in one
of his Soekris boards. As usual, addiction was
instant and by the grace of the "you touch it, you
own it" principle, he has been fiddling the crypto
framework more than is good for him.

A hands-on testing and debugging session of the
Firewire stack in FreeBSD.
Everyone who wishes to attend should bring their
Firewire devices, ext Drives and Cameras, and their
Laptops. I will be debugging and capturing data
points to enhance and improve features in the
Firewire stack.
We should be able to knock out quite a bunch of
bugs if folks can bring their various Firewire
devices along with their various PCs.
Even if your Firewire device works perfectly, bring
it by so it can be documented as supported by the
Firewire team!

Building the Network You Need with PF, the OpenBSD
packet filter.
Building the network you need is the central theme
for any network admin. This tutorial is for aspiring
or seasoned network professionals with at least a
basic knowledge of networking in general and TCP/IP
particular. The session aims at teaching tools and
techniques to make sure you build your network to
work the way it's supposed to, keeping you in charge.
Central to the toolbox is the OpenBSD PF packet
filter, supplemented with tools that interact with
it. Whether you are a greybeard looking for ways
to optimize your setups or a greenhorn just starting
out, this session will give you valuable insight
into the inner life of your network and provide
pointers to how to use that knowledge to build the
network you need. The session will also offer some
fresh information on changes introduced in OpenBSD
4.5, the most recent version of PF and OpenBSD. The
tutorial is loosely based on Hansteen's recent book,
/The Book of PF/ (No Starch Press), with updates
and adaptations based on developments since the
book's publication date.

Networking from the Bottom Up: Device Drivers.
In this tutorial I will describe how to write and
maintain network drivers in FreeBSD and use the
example of the Intel Gigabit Ethernet driver (igb)
throughout the course.
Students will learn the basic data structures and
APIs necessary to implement a network driver in
FreeBSD. The tutorial is general enough that it can
be applied to other BSDs, and likely to other
embedded and UNIX like systems while being specific
enough that given a device and a manual the student
should be able to develop a working driver on their
own. This is the first of a series of lectures on
network that I am developing over the next year or
so.
The i in iSCSI stands for internet, some say for
insecure, personally I like to think interesting.
I'll try to share the road followed from RFC-3720
to the actual working driver, the challenges, the
frustrations.
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 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

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:

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.
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).
The traditional closing...

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.

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.

The X window system has been changing a lot in the
recent years, and still changing. This talk will
present this evolution, summarizing what has already
been done and showing the current roadmap for future
evolutions, with some focus on how *BSD kernels can
be affected by the developments done with Linux as
the primary target.

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.

Recently I have been attending Hostobzor 12th, the
Russian conference of hosting providers, beeing
held at Raivola hotel near St. Petersburg. The event
was great as always thanks to organizers. There was
a number of intersting talks given, a lot of
interesting discussions held, and, what I appreciate
better, a lot of new people with great ideas met.
I gave a talk on using the FreeBSD Ports system to
mange a large-scale virtual hosting installations
based on Hosting Telesystems experience. I tried
to describe in detail how we use the ports collection
to deploy a large number of servers diverced by
architecture and OS versions, how we build packages
and distribute them among servers, talked about how
we use Mercurial VCS to incrementally merge upstream
changes into our modified ports collection and
FreeBSD src trees. Hopefully, I've not screwed it
much... At least, some people was interested a lot
and asked interesting questions.

Introduction
This page contains information about the FreeBSD port to the
32- and 64-bit ARM architectures and hardware.
Discussion of the ARM ports takes
place on the
freebsd-arm
mailing list.
32-bit ARM is officially a
Tier 2
architecture, as the FreeBSD project
does not provide official releases or pre-built packages for this
platform due to it primarily targeting the embedded arena. However,
FreeBSD/ARM is being actively developed and maintained, is well supported,
and provides an excellent framework for building ARM-based
systems. FreeBSD/arm supports ARMv4 and ARMv5
processors. FreeBSD/armv6 supports ARMv6 and ARMv7 processors,
including SMP on the latter.
Initial support for 64-bit ARM is complete.
64-bit ARM platforms follow a set of standard conventions, and a single
&os; build will work on hardware from multiple vendors.
As a result, &os; will provide official releases for FreeBSD/arm64 and
packages will be available. FreeBSD/arm64 is on the path to becoming a
Tier 1
architecture.
FreeBSD/arm and FreeBSD/armv6 support a large range of
ARM CPUs and development boards. Not every peripheral is supported on
every CPU or board, though work continues towards this and contributions
are always welcome. Conversely, many CPUs and boards not listed may
work with only minimal changes needed.
Listing all supported devices on all CPUs and boards is impractical here,
however much information can be obtained from the mailing list and
archives, the FreeBSD/arm
Wiki pages, and also from the

&os;/&arch.pc98; is a port of &os; which aims to run
on the NEC PC-98x1 (pc98) architecture.
The project's goal is to make &os;/&arch.pc98; work
the same as FreeBSD on other architectures.
Most of the kernel source is already included in the FreeBSD source tree
and most of the userland utilities built from the source work fine.
Status
&os;/&arch.pc98; is a
Tier 2 architecture at the time of 9.0-RELEASE.
Although
FreeBSD/pc98 was a Tier 1 for a long time since 5.0-RELEASE, it was
downgraded due to FreeBSD no longer supporting installation from
floppy disks, and most pc98 machines cannot boot from CD/DVD.
Although later pc98 machines can boot from CDROM, FreeBSD's support
for that has not been integrated into bsdinstall and release tools.
The FreeBSD/ppc project pages contain information about the FreeBSD
port to the PowerPC® architecture. As with the port itself, these
pages are still a work in progress.
The FreeBSD/ppc port is still a
Tier 2 platform. That means it is
not being fully supported by our security officer, release engineers and
toolchain maintainers.
ISO images of FreeBSD &rel.current; suitable for New-World Macs are
available for download, for details on how to obtain these see the
release announcement.
The powerpc64 port provides a 64-bit kernel and userland, and is supported
on all 64-bit CPUs. Users of 32-bit CPUs (G3, G4) must use the 32-bit
powerpc platform, users of 64-bit CPUs that support 32-bit operating
systems (G5) have a choice, and users of 64-bit CPUs that do not (Cell)
must use powerpc64. For those users with a choice, powerpc64 provides
some additional features (the ability to use more than 2 GB of RAM and
ZFS support) while having slightly worse ports support due to being
a newer and less common architecture. Like other 64-bit platforms,
FreeBSD/powerpc64 supports running 32-bit binaries as well as 64-bit ones.
Peter Grehan is the project
leader. Contact him if you can contribute code. If you just want
to know about the status of this project, check this page
regularly or join the
FreeBSD/ppc mailing list.
The FreeBSD/ppc port should run on any New-World Apple machine (any Apple
machine with a built-in USB port), as well as the Sony Playstation 3. A
port to IBM pSeries hardware is in progress. People reported FreeBSD runs
on following machines:
There is a known bug in the boot-loader, that prevents you from
loading an alternate kernel, so testing your kernel is a bit risky.
When booting the loader from the Open Firmware prompt, give it a
partition which is either non-existent, doesn't have a kernel to load,
or isn't a UFS partition:
0 > boot hd:loader hd:0
At this point, you can set currdev and manually load a kernel:
OK set currdev="hd":14
OK load /boot/kernel/kernel.save
Work with the RE team to determine which pre-built packages
can be included on the default install ISOs.
Manage commits to the CVS tree for package builds via the
following steps:
Institute a freeze and produce packages for all the
appropriate architectures. Often this process has to be
repeated because either bugs are identified in various ports,
or changes to the src tree create a risk that the packages
that have already been built would not work with those
changes.
To make sure that package builds are consistent and correct,
all commits must be approved by portmgr during a
freeze. Changes that are generally approved are:
fixes to make a package build at all;
security fixes to critical packages;
problems that are noticed with licensing issues.
Unfortunately, due to the sheer size of the Ports Collection
and the speed that applications are developed, it is
impossible to fix every single problem for a release.
The tree is then locked for all commits and a CVS tag is laid
down.
The tree is then unlocked and a slush is
announced. The intent of this state is to allow routine
changes to be made to the Ports Collection, but with the note
that these changes will not ship on the release ISOs. What
we particularly want to avoid is
sweeping changes.
The reason we want to avoid these commits is if some kind
of show-stopper problem is found (either security- or license-
related) such that we need to make a change that can go on
the release ISOs, we will need to slip the CVS tag on the
changed file(s). By allowing unlimited commits, the risk is
high that any such change would involve having to recreate all
the packages all over again, resulting in an endless release
cycle.
Only once the RE team and portmgr are happy with the final
state of the release ISOs is the ports tree completely available
for commits again.
Manage the Ports Build
Cluster machines. These machines continually build packages
on all possible combinations of OS release and CPU architecture
(in our terminology, build environments.)
These builds also produce error logs for packages that do not
build correctly (see the above URL). Periodically, the team
marks these ports as BROKEN so that maintainers may be notified.
(See below.)
Successfully built packages (at least, the ones that are freely
redistributable) are also copied to the master FTP server and thus
become the default "latest package" for installations
that use packages rather than ports.
Notify the FreeBSD community of problems within the Ports
Collection so that problems do not get overlooked. To do this,
there are a number of emailed reports. Ones marked
public are posted to freebsd-ports.
a public list of all ports to be removed due to security
problems, build failures, or general obsolescence, unless they
are fixed first.
private email to all maintainers of the affected ports
(including ports dependent on the above).
private email to all maintainers of ports that are already
marked BROKEN and/or FORBIDDEN.
private email to maintainers who are not committers, who have
PRs filed against their ports (to flag PRs that might never have
been Cc:ed to them).
public email about port commits that break building of
INDEX.
public email about port commits that send the revision
metadata backwards (and thus confuse tools like portupgrade).
a public list of all ports that have at least one file
that fails to fetch from any non-FreeBSD mastersite. For the
complete list of results for all files versus all mastersites,
- see
+ see
Emanuel Haupt's port survey.
private email to an affected port maintainer when a port
is about to be marked BROKEN, Cc:ed to the last committer to
the port. (This email is not automated but it should be sent
as a courtesy.)
Remove expired ports. Ports that have been marked BROKEN for
some time are marked DEPRECATED (with an EXPIRATION_DATE) and then
are removed if no one has fixed them by that time. The intent of
this this process is to try to insure that if a user installs a port,
there is the best possible change that it can be made to work.
In other cases, ports are marked DEPRECATED when they have been
replaced by a newer version and the older version is no longer
maintained by the authors. The EXPIRATION_DATE should generally
be set at least two months in the future to allow everyone sufficient
time to upgrade.
CVSweb is a WWW interface for CVS repositories with which you
can browse a file hierarchy on your browser to view each file's
revision history in a very handy manner.
CVSweb was originally written by &a.fenner; for the FreeBSD
Project, and instantly won great popularity among software
developers for its usability.
Please note that CVSweb is no longer
maintained, and is no longer in use within the FreeBSD Project.
There may be unpatched security issues with the code available on
this page. The information and files available here are retained
for historical interest only; we can not recommend anybody use the
code available here without an understanding that any security
issues discovered will not be fixed.
FreeBSD-CVSweb, formerly known as knu-CVSweb, is an enhanced
version of CVSweb based on Henner Zeller's CVSweb, which is an extended
version of the original CVSweb.
&a.knu; made numerous cleanups, bug-fixes, security enhancements and
feature improvements over the version and brought it back where it was
born. Ville Skyttä continued that work; the project was most
recently maintained by Jonathan Noack.
Download the tarball from the following sites. The latest
stable release is 3.0.6 (released 2005-09-25), see
the NEWS and ChangeLog files within the tarball for changes.
See the FreeBSD FTP Sites document for information about mirror sites.
Legacy versions are also available from the above distribution
directories. Upgrading to 3.x is recommended, but if you're stuck with
Perl older than 5.6, use a 2.0.x version instead.
A number of operating system distributions contain a pre-packaged
FreeBSD-CVSweb:
FreeBSDport (devel/cvsweb3 has 3.x,
devel/cvsweb 2.x)
In addition to the mainstream development path of FreeBSD, a number
of developer groups are working on the cutting edge to expand
FreeBSD's range of applications in new directions. Follow the links
below to learn more about these exciting projects.
If you feel that a project is missing, please send the URL and a short
description (3-10 lines) to
www@FreeBSD.org.
In addition, some of these projects regularly submit status reports,
which can be viewed on the status
reports page.

SYSLOG-SECURE:
In August 2001 a standard of syslog was made: RFC3164. This RFC
describes some extensions to add security to syslog. A project
started in 2002 to adapt RFC3164 to the FreeBSD version of syslog and to add
some security extensions, at least syslog-sign. Both libc and syslogd will
be modified. And optionally some tools to verify or manage the security
would be made.
All help is welcome. Send an email to albert@ons-huis.net for info.
Storage
Arla:
A free AFS client implementation. The main goal is to
make a fully functional client with all capabilities of normal AFS.
Other planned and implemented things are all the normal management
tools and a server.
Coda:
A distributed filesystem. Among its features are disconnected
operation, good security model, server replication and persistent
client side caching.
Tertiary Disk:
A storage system architecture to create large disk storage systems
that avoid the disadvantages of custom built disk arrays. The
name comes from twin goals: to have the cost per megabyte and
capacity of tape libraries and the performance of magnetic
disks. We use commodity, off the shelf components to develop a
scalable, low cost, terabyte capacity disk system. Our target is
to build a complete storage system with about 30-50% extra to
the cost of the raw disk. Tertiary Disk uses PCs connected by a
switched network to host a large number of disks. Our prototype
consists of 20 200MHz PC PCs, which host 370 8GB disks. The PCs
are connected through a 100Mbps Ethernet switch.
Vinum:
A logical volume manager modeled after the VERITAS volume manager™.
However, it is not a clone of Veritas, and attempts to solve a
number of problems more elegantly than Veritas. It also offers
features that Veritas does not have.
Kernel, security
OpenBSM: An open
source implementation of Sun's Basic Security Module (BSM) Audit API and file
format. OpenBSM provides the userland libraries, tools, and documentation
for the TrustedBSD audit implementation that will be integrated into
FreeBSD.
TrustedBSD:
Provides a set of trusted operating system extensions to the FreeBSD operating
system. This includes features such as fine-grained privileges (capabilities),
Access Control Lists, and Mandatory Access Control. These features are
being integrated back into the base FreeBSD distribution, as well as being
ported to other BSD-derived systems.
Kernel Stress Test Suite: The
purpose of this stress test is to crash the system. The stress test
is composed of small test programs and scripts. Each test targets a
specific area of the kernel. The key concept of this test suite is
chaos. Each test sleeps for a random number of seconds before it
starts up in a random number of invocations.
Device drivers
busdma
and SMPng driver conversion: busdma provides a portable abstraction
to the Direct Memory Access (DMA) hardware primitives used by many high
performance device drivers. By using this abstraction, device driver
authors avoid adding platform-specific DMA management code, improving
the portability of drivers between hardware architectures. This page
also tracks the progress of drivers towards being SMPng-safe.
Home Automation:
Using FreeBSD to run appliance controllers, infra-red controllers,
automated telephone systems, and more.
Xircom CEM Ethernet Driver: A mailing list exists for further
development of Scott Mitchell's Xircom CEM ethernet driver. Send

Architecture
Porting FreeBSD to IA-64 systems:
This project is responsible for porting FreeBSD to the IA-64
architecture. Direct any questions specific to this project to the
freebsd-ia64@FreeBSD.org mailing list.
Porting FreeBSD to SPARC® systems:
Contains information on the FreeBSD SPARC port including a FAQ,
some early boot code, information on SPARC processors and motherboards,
and other SPARC projects.
SysVR4 Emulation: This page describes an SysVR4 emulator for
FreeBSD. It is currently capable of running (or walking, in some
cases) a wide-ish variety of SysV executables taken from Solaris™/x86
2.5.1 and 2.6 systems. I have reason to believe that it will also run
SCO UnixWare and SCO OpenServer binaries.
The OSKit:
The OSKit is a framework and a set of 31 component libraries oriented
to operating systems, together with extensive documentation. By
providing in a modular way not only most of the infrastructure
"grunge" needed by an OS, but also many higher-level components, the
OSKit's goal is to lower the barrier to entry to OS R&D and to
lower its costs. The OSKit makes it vastly easier to create a new OS,
port an existing OS to the x86 (or in the future, to other
architectures supported by the OSkit), or enhance an OS to support a
wider range of devices, filesystem formats, executable formats, or
network services. The OSKit also works well for constructing OS-related
programs, such as boot loaders or OS-level servers atop a
microkernel.
Misc
NanoBSD:
NanoBSD is a tool designed to create a possibly reduced FreeBSD
system image, which is suited to fit on a Compact Flash card
(or other mass storage medium) in a way which is suitable for
use in appliance like applications. The FreeBSD documentation
collection includes an introductory
article about NanoBSD,
which includes useful tips about setting up, running and
using NanoBSD.
GLOBAL:
A common source code tag system that works the same way across
diverse environments. Currently, it supports the shell command line,
the nvi editor, web browser, the emacs editor, and the elvis editor,
and the supported languages are C, Yacc, and Java.
ACPI on FreeBSD:
A Project created to get ACPI working smoothly on FreeBSD.
Binary
Updater: FreeBSD Update is a system for automatically
building, distributing, fetching, and applying binary security
updates for FreeBSD. This makes it possible to easily track
the FreeBSD security branches without the need for fetching
the source tree and recompiling (except on the machine
building the updates, of course). Updates are
cryptographically signed; they are also distributed as binary
diffs using a binary diff tool, which dramatically reduces
the bandwidth used.
CVSweb: A WWW
interface for CVS repositories with which you can browse a file
hierarchy on your browser to view each file's revision history
in a very handy manner.
TET
Integration: The Test Execution Toolkit from The Open Group is a
light-weight open-source test execution framework that
supports distributed testing. This project investigates
using TET and existing TET-based open-source standards-compliance
test suites (VSX-PCTS, VSC-Lite, VSTH-Lite, VSW5 and others) in
FreeBSD.
Each distribution of FreeBSD includes several documentation
files describing the particular distribution (RELEASE,
SNAPSHOTs, etc.). These files typically include:
README: General introduction.
Release Notes: Information about changes from the
previous release of FreeBSD.
Hardware Notes: A list of hardware devices known to work
with FreeBSD.
Installation Instructions: A brief guide to installing
FreeBSD.
Errata: Late-breaking news, including corrections,
security advisories, and potential problems found after each
release.
The release notes, hardware notes, and
installation instructions are customized for each architecture
supported by FreeBSD.
RELEASE versions of FreeBSD
The release documentation for each -RELEASE version of FreeBSD
(for example, &rel.current;-RELEASE) can be found on the
releases page of
the FreeBSD web site and on mirror sites.
These files are located
in the top-level directory of each distribution. Both
HTML and text forms are usually provided.
Snapshot Versions of FreeBSD
The release documentation files for snapshots are generally
in the top-level directory of each snapshot.
Documentation for -CURRENT and -STABLE
HTML versions of the release
documentation for FreeBSD -CURRENT and FreeBSD -STABLE are
available on the FreeBSD web site. These documents are
continually changing and automatically generated. The versions on the web site are rebuilt
at the same time that the rest of the web site is updated.
