Kristaps Dzonsons - Process isolation for NetBSD and OpenBSD
Source: DCBSDCon
Added: 24 May 2009
Tags: dcbsdcon, dcbsdcon2009, slides, openbsd, netbsd, process isolation, kristaps dzonsons
PDF (687 Kb, 27 pages)
In NetBSD and OpenBSD, user-land process and
process-context isolation is limited to credential
cross-checks, file-system chroot and explicit
systrace/kauth applications. I'll demonstrate a
working mechanism of isolated process trees in
branched OpenBSD-4.4 and NetBSD-5.0-beta kernels
where an isolated process is started by a system
call similar to fork; following that, the child
process and its descendants execute in a context
isolated from the caller. This system is the continued
work of "mult" -- first prototyped in a branched
NetBSD-3.1 kernel and isolating all system resources
-- pared down to a lightweight, auditable patch of
process-only separation for both OpenBSD and NetBSD.
I specifically address solutions to performance
issues and mechanism design with an eye toward more
resources being isolated in the future.

PDF (675 Kb, 32 pages)
I will discuss the current status of kernel SMP
support, the rthreads thread library, and relevant
future developments. Over the years, we have
accumulated several concurrency primitives in the
kernel, causing some confusion amongst developers,
so I will lay out the origin and correct usage for
each. The talk is primarily targeted at the budding
OpenBSD kernel developer, but I will also describe
the end-user effects of each topic.

MP3 (1 byte, 47 minutes), OGG (1 byte, 47 minutes), PDF (1 byte, n pages)
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.
Originally based on some ideas from NetBSD, the
framework has sustained many improvements in OpenBSD,
and was ported and committed to FreeBSD and DragonFly
BSD.
Constantine A. Murenin is an MMath graduate student
at the David R. Cheriton School of Computer Science
at the University of Waterloo (CA). Prior to his
graduate appointment, Constantine attended and
subsequently graduated from East Carolina University
(US) and De Montfort University (UK), receiving two
bachelor degrees in computer science, with honors
and honours respectively. A FreeBSD Google Summer
of Code 2007 Student, OpenBSD Committer and Mozilla
Contributor, Constantine's interests range from
standards compliance and usability at all levels,
to quiet computing and hardware monitoring.

MP3 version (11 Mb, 103 minutes)
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.

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.

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.
OpenBSD 4.3 Release Song - "Home to Hypocrisy"

Ogg version (6.5 Mb, 4 minutes 48 seconds), MP3 version (8.2 Mb, 4 minutes 48 seconds)
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.

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.

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.
