o An in-kernel getcwd(3) implementation.
o A new system call adjfreq(2) to allow ntpd(8) to adjust the tick rate of the system clock automatically.
o Support for X11 on VAX has been added
o Virtual Allocation Table (VAT) support for UDF.
o C99 functions round(3), roundf(3), trunc(3), and truncf(3) have been added to libm, the math library.
o pf(4) now supports Unicast Reverse Path Forwarding (uRPF) checks for simplified ingress filtering.
o bpf(4) can now ignore packets based on their direction (inbound/outbound) using the BIOCSDIRFILT ioctl.

o Equal cost multipath routing support. Needs to be enabled by a sysctl.
o Prebind, a secure implementation of prelinking, has been added to ldconfig(8), it speeds up launching of shared binaries. Prebind is compatible with address space randomization, unlike prelink.
o vnconfig(8) can now use PKCS #5 PBKDF2 to create a more secure key when using encryption.
- Assorted improvements and code cleanup:
o Much better time keeping for multiprocessor OpenBSD/i386 systems.
o Much improved implementation of telldir(3) and friends.
o Replacement of many malloc(3) calls that follow a pattern prone to integer overflow with safer constructs.

o X Window aperture support, where available, now defaults to off
- New functionality for hostapd(8), the Host Access Point Daemon:
o IP based roaming to build wireless networks without the requirement of a single broadcast domain.
o New event rules to match optional elements of radiotap headers: signal percentage, transmit rate and channel frequency.
o Various bug fixes and improvements.
- OpenSSH 4.4:
o Conditional configuration in sshd_config(5) using the Match directive. This allows some configuration options to be selectively overridden if specific criteria (based on user, group, hostname and/or address) are met.
o Add support for Diffie-Hellman group exchange key agreement with a final hash of SHA256.
o Added a ForceCommand directive to sshd_config(5), similar to the command="..." option in ~/.ssh/authorized_keys.
o Added a PermitOpen directive to sshd_config(5), similar to the permitopen="..." option in authorized_keys, to allow control over the port-forwardings that a user is allowed to establish.
o Added an ExitOnForwardFailure option to cause ssh(1) to exit (with a non-zero exit code) when requested port forwardings could not be established.
o Added optional logging of transactions to sftp-server(8).
o ssh(1) will now record port numbers for hosts stored in ~/.ssh/authorized_keys when a non-standard port has been requested.

o allow bgpd to manipulate carp demotion counters based on session states, gives even greater failover support
o support restarting sessions that reached max-prefix after a given time
o bgpctl can now show all routes received from a neighbor before filters were applied, and routes sent to neighbors
o assorted fixes and improvements, as usual
- OpenOSPFD 4.0:
o Track uptime of the daemon itself.
o Track uptime of all ospf enabled interfaces.
o Adjust logging behaviour to prevent unwanted logging.
o Delay LSA updates when removing and adding - prevent flapping.
o Fix plaintext authentication.
o Improve the output of 'ospfctl show interfaces'.
o Support rtlabels when redistributing routes.
- OpenNTPD 4.0:
o support timedelta sensors, such as DCF77 receivers supported by udcf(4) and GPS receivers supported by nmea(4).
o Adjust the kernel tick frequency, using adjfreq(2), improving accuracy on many machines.

If you'd like to see a list of what has changed between OpenBSD 3.9 and 4.0, look at http://www.OpenBSD.org/plus40.html
Even though the list is a summary of the most important changes made to OpenBSD, it still is a very very long list.
- SECURITY AND ERRATA
We provide patches for known security threats and other important issues discovered after each CD release. As usual, between the creation of the OpenBSD 4.0 FTP/CD-ROM binaries and the actual 4.0 release date, our team found and fixed some new reliability problems (note: most are minor and in subsystems that are not enabled by default). Our continued research into security means we will find new security problems -- and we always provide patches as soon as possible. Therefore, we advise regular visits to:
Security patch announcements are sent to the security-announce@OpenBSD.org mailing list. For information on OpenBSD mailing lists, please see:
- CD-ROM SALES
OpenBSD 4.0 is also available on CD-ROM. The 3-CD set costs $50USD (EUR 50 including VAT) and is available via mail order and from a number of contacts around the world. The set includes a colourful booklet
which carefully explains the installation of OpenBSD. A new set of cute little stickers is also included (sorry, but our FTP mirror sites do not support STP, the Sticker Transfer Protocol). As an added bonus, the second CD contains an audio track, a song entitled "Humppa Negala".
OpenBSD 4.0 comes with another OpenBSD Audio CD which celebrates the artwork and songs that have been released with each OpenBSD release. All the songs from the 3.0 to 4.0 releases are included (plus one bonus
track by Ty Semaka explaining his role in the development of the art that accompanies OpenBSD releases). Includes a 11cm silver-on-clear die-cut wireframe Puffy sticker!
Lyrics (and an explanation) for the songs may be found at:
Profits from CD sales are the primary income source for the OpenBSD project -- in essence selling these CD-ROM units ensures that OpenBSD will continue to make another release six months from now.
The OpenBSD 4.0 CD-ROMs are bootable on the following five platforms:
o sparc64 (UltraSPARC)
(Other platforms must boot from floppy, network, or other method).
For more information on ordering CD-ROMs, see:
The above web page lists a number of places where OpenBSD CD-ROMs can be purchased from. For our default mail order, go directly to:
or, for European orders:
All of our developers strongly urge you to buy a CD-ROM and support our future efforts. Additionally, donations to the project are highly appreciated, as described in more detail at:
- T-SHIRT SALES
The project continues to expand its funding base by selling t-shirts and polo shirts. And our users like them too. We have a variety of shirts available, with the new and old designs, from our web ordering system at:
and for Europe:
The OpenBSD 4.0 t-shirts are available now. The new shirt for 4.0 is a colourful parody of a well-known French comic. We also sell our older shirts, as well as a selection of OpenSSH t-shirts.
- FTP INSTALLS
If you choose not to buy an OpenBSD CD-ROM, OpenBSD can be easily installed via FTP. Typically you need a single small piece of boot media (e.g., a boot floppy) and then the rest of the files can be installed from a number of locations, including directly off the Internet. Follow this simple set of instructions to ensure that you find all of the documentation you will need while performing an install via FTP. With the CD-ROMs, the necessary documentation is easier to find.
1) Read either of the following two files for a list of ftp mirrors which provide OpenBSD, then choose one near you:
As of Nov 1, 2006, the following ftp mirror sites have the 4.0 release:
ftp://ftp3.usa.openbsd.org/pub/OpenBSD/4.0 CO, USA
ftp://ftp5.usa.openbsd.org/pub/OpenBSD/4.0 CA, USA
ftp://rt.fm/pub/OpenBSD/4.0 IL, USA
The release is also available at the master site:
ftp://ftp.openbsd.org/pub/OpenBSD/4.0/ Alberta, Canada
However it is strongly suggested you use a mirror.
Other mirror sites may take a day or two to update.
2) Connect to that ftp mirror site and go into the directory pub/OpenBSD/4.0/ which contains these files and directories. This is a list of what you will see:
ANNOUNCEMENT alpha/ luna88k/ sgi/
Changelogs/ amd64/ mac68k/ sparc/
HARDWARE armish/ macppc/ sparc64/
PACKAGES cats/ mvme68k/ src.tar.gz
PORTS ftplist mvme88k/ sys.tar.gz
README hp300/ packages/ tools/
SIZES hppa/ ports.tar.gz vax/
XF4.tar.gz i386/ root.mail zaurus/
It is quite likely that you will want at LEAST the following files which apply to all the architectures OpenBSD supports.
README - generic README
HARDWARE - list of hardware we support
PORTS - description of our "ports" tree
PACKAGES - description of pre-compiled packages
root.mail - a copy of root's mail at initial login.
(This is really worthwhile reading).
3) Read the README file. It is short, and a quick read will make sure you understand what else you need to fetch.
4) Next, go into the directory that applies to your architecture, for example, i386. This is a list of what you will see:
CKSUM bsd.rd etc40.tgz misc40.tgz
INSTALL.i386 cd40.iso floppy40.fs pxeboot
INSTALL.linux cdboot floppyB40.fs xbase40.tgz
MD5 cdbr floppyC40.fs xetc40.tgz
base40.tgz cdemu40.iso game40.tgz xfont40.tgz
bsd cdrom40.fs index.txt xserv40.tgz
bsd.mp comp40.tgz man40.tgz xshare40.tgz
If you are new to OpenBSD, fetch _at least_ the file INSTALL.i386 and the appropriate floppy*.fs or cd40.iso file. Consult the INSTALL.i386 file if you don't know which of the floppy images you need (or simply fetch all of them).
5) If you are an expert, follow the instructions in the file called README; otherwise, use the more complete instructions in the file called INSTALL.i386. INSTALL.i386 may tell you that you need to fetch other files.
6) Just in case, take a peek at:
This is the page where we talk about the mistakes we made while creating the 4.0 release, or the significant bugs we fixed post-release which we think our users should have fixes for. Patches and workarounds are clearly described there.
Note: If you end up needing to write a raw floppy using Windows, you can use "fdimage.exe" located in the pub/OpenBSD/4.0/tools directory to do so.
- X.ORG FOR MOST ARCHITECTURES
X.Org has been integrated more closely into the system. This release contains X.Org 6.9.0. Most of our architectures ship with X.Org, including amd64, sparc, sparc64 and macppc. During installation, you can install
X.Org quite easily. Be sure to try out xdm(1) and see how we have customized it for OpenBSD.
- PORTS TREE
The OpenBSD ports tree contains automated instructions for building third party software. The software has been verified to build and run on the various OpenBSD architectures. The 4.0 ports collection, including many of the distribution files, is included on the 3-CD set. Please see the PORTS file for more information.
Note: some of the most popular ports, e.g., the Apache web server and several X applications, come standard with OpenBSD. Also, many popular ports have been pre-compiled for those who do not desire to build their own binaries (see BINARY PACKAGES, below).
- BINARY PACKAGES WE PROVIDE
A large number of binary packages are provided. Please see the PACKAGES file (ftp://ftp.OpenBSD.org/pub/OpenBSD/4.0/PACKAGES) for more details.
- SYSTEM SOURCE CODE
The CD-ROMs contain source code for all the subsystems explained above, and the README (ftp://ftp.OpenBSD.org/pub/OpenBSD/4.0/README) file explains how to deal with these source files. For those who are doing an FTP install, the source code for all four subsystems can be found in the pub/OpenBSD/4.0/ directory:
XF4.tar.gz ports.tar.gz src.tar.gz sys.tar.gz
OpenBSD 4.0 includes artwork and CD artistic layout by Ty Semaka, who also arranged an audio track on the OpenBSD 4.0 CD set. Ports tree and package building by Peter Valchev, Nikolay Sturm and Christian Weisgerber. System builds by Theo de Raadt, Kenji Aoyama, and Miod Vallat. X11 builds by Todd Fries. ISO-9660 filesystem layout by Theo de Raadt.
We would like to thank all of the people who sent in bug reports, bug fixes, donation cheques, and hardware that we use. We would also like to thank those who pre-ordered the 4.0 CD-ROM or bought our previous
CD-ROMs. Those who did not support us financially have still helped us with our goal of improving the quality of the software.
