The OpenBSD project has released OpenBSD 3.3 with an impressive array of exciting new features. A complete list of changes can be found here. Todd C. Miller summarizes in his release announcement:

"We believe this is our best release ever with cool new features including ProPolice stack protection in the compiler [story], queue support for pf (traffic shaping) [story], an hppa (pa-risc) port, W^X for some platforms (sparc, sparc64, alpha and hppa) [story], privilege separation in the X server and xconsole, fewer setuid binaries, a new spam deferral daemon and much, much more."

OpenBSD 3.3 can be freely downloaded from a local FTP mirror, or purchased as an inexpensive 3-CD set, which includes images for i386, MacPPC, Vax, Sparc, and Sparc64. Versions for Alpha, HP300, HPPA, Mac68k and MVME68k are available by FTP. The project's homepage states, "OpenBSD is developed by volunteers. The project funds development and releases by selling Cd's and T-shirts, as well as receiving donations. Organizations and individuals donate and thus ensure that OpenBSD will continue to exist, and will remain free for everyone to use and reuse as they see fit." For a detailed description of the new features found in 3.3, read on.

OpenBSD 3.3 has been released and is now available from select ftp
mirrors.  We believe this is our best release ever with cool new
features including ProPolice stack protection in the compiler
(http://www.trl.ibm.com/projects/security/ssp/), queue support for
pf (traffic shaping), an hppa (pa-risc) port, W^X for some platforms
(sparc, sparc64, alpha and hppa), privilege separation in the X
server and xconsole, fewer setuid binaries, a new spam deferral
daemon and much, much more.

Full release announcement follows:

------------------------------------------------------------------------
- OpenBSD 3.3 RELEASED -------------------------------------------------

May 1, 2003.

We are pleased to announce the official release of OpenBSD 3.3.
This is our 13th release on CD-ROM (and 14th via FTP).  We remain
proud of OpenBSD's record of seven years with only a single remote
hole in the default install.  As in our previous releases, 3.3
provides significant improvements, including new features, in nearly
all areas of the system:

- Ever-improving security            (http://www.OpenBSD.org/security.html)

  o Integration of the ProPolice stack protection technology, by
    Hiroaki Etoh, into the system compiler.  This protection is
    enabled by default.  With this change, function prologues are
    modified to rearrange the stack: a random canary is placed
    before the return address, and buffer variables are moved closer
    to the canary so that regular variables are below, and harder
    to smash.  The function epilogue then checks if the canary is
    still intact.  If it is not, the process is terminated.  This
    change makes it very hard for an attacker to modify the return
    address used when returning from a function.

  o W^X (pronounced: "W xor X") on architectures capable of pure
    execute-bit support in the MMU (sparc, sparc64, alpha, hppa).
    This is a fine-grained memory permissions layout, ensuring
    that memory which can be written to by application programs can
    not be executable at the same time and vice versa. This raises
    the bar on potential buffer overflows and other attacks: as a
    result, an attacker is unable to write code anywhere in memory
    where it can be executed. (NOTE: i386 and powerpc do not support
    W^X in 3.3; however, 3.3-current already supports it on i386,
    and both these processors are expected to support this change
    in 3.4.)

  o Further reduction of the number of setuid and setgid binaries
    and more use of chroot(2) throughout the system.  While some
    programs are still setuid or setgid, most allocate a resource
    and then quickly revoke privilege.

  o The X window server and xconsole now use privilege separation,
    for better security. Also, xterm has been modified to do privilege
    revocation. xdm runs as a special user and group, to further
    constrain what might go wrong.

  o RSA blinding is now on by default in OpenSSL.

  o Many occurrences of strcpy(), strcat() and sprintf() have been changed
    to strlcpy(), strlcat(), and snprintf() or asprintf().

  o A process will now have the P_SUGIDEXEC flag set if any of the
    real, effective, or saved uid/gid are mismatched.  Previously
    only the real and effective uid/gid were checked.

  o ptrace(2) is now disabled for processes with the P_SUGIDEXEC flag
    set.

- Improved hardware support             (http://www.OpenBSD.org/plat.html)

  o The xl(4), sis(4) and vr(4) ethernet drivers are more robust.

  o The ahc(4) and bktr(4) drivers now work on macppc.

  o Vlan tagging now works properly in the ti(4) driver.

  o The cac(4) driver is now more stable.

  o Media handling has been improved in the hme(4) driver.

  o Bugs have been fixed in the gem(4) driver to make it more stable
    on the sparc64 platform.

  o Several fixes for the ami(4) driver.

  o New LZS compression support for the hifn(4) driver.

  o Support for new IDE controllers from Promise, VIA, NVIDIA and ServerWorks.

  o siop(4) driver improvements.

  o The sparc64 platform is now supported on several more models and
    is much more stable.

- Major improvements in the pf packet filter, including:

  o pf now supports altq-style queueing via the new "queue"
    directive.  Packets are assigned to queues based on filter
    rules.  This allows for very flexible queue settings, including
    quality of service bandwidth shaping.

  o New support for "anchors," which allows the use of sub-rulesets
    which can be loaded and modified independently.

  o A new "table" facility provides a mechanism for increasing the
    performance and flexibility of rules with large numbers of source
    or destination addresses.

  o Address pools, redirect/NAT to multiple addresses and thus load
    balancing.

  o The scrub option 'no-df' has been changed to better handle fragments
    with DF set, such as those sent by Linux NFS.

  o There is a new 'random-id' option for the scrub rules.  This randomizes
    outbound IP IDs and helps defeat NAT detection.

  o TCP state inspection is now RFC 763 compliant; we now send a
    reset when presented with SYN-cookie schemes that send out-of-window
    ACKs during the TCP handshake.

  o TCP window scaling support.

  o Full support for CIDR addresses.

  o Early checksum verification return on invalid packets.

  o The configuration language has been made much more flexible.

  o Large rulesets now load much more quickly.

- New subsystems included with 3.3

  o spamd, a spam deferral daemon, can be used to tie up resources
    on a spammer's machine.  spamd uses the new pf(4) table facility
    to redirect connections from a blacklist such as SPEWS or DIPS.

  o OpenBSD 3.3 includes the hppa port for HP PA-RISC machines.
    This should be considered a work in progress; users are advised
    to install the most recent snapshot instead of the formal 3.3
    hppa release.

- Many other bugs fixed                 (http://www.OpenBSD.org/plus33.html)

- The "ports" tree is greatly improved  (http://www.OpenBSD.org/ports.html)

  o The 3.3 CD-ROMs ship with many pre-built packages for the common
    architectures.  The FTP site contains hundreds more packages
    (for the important architectures) which we could not fit onto
    the CD-ROMs (or which had prohibitive licenses).

- Many subsystems improved and updated since the last release:

  o XFree86 4.2.1 (+ patches).

  o gcc 2.95.3 (+ patches and ProPolice).

  o Sendmail 8.12.9.

  o Apache 1.3.27 and mod_ssl 2.8.12, DSO support (+ patches).

  o OpenSSL 0.9.7beta3 (+ patches).

  o Stable version of KAME IPv6.

  o OpenSSH 3.6 (now 100% compliant with the secsh drafts).

  o Bind 9.2.2 (+ patches).

  o Perl 5.8.0

  o Sudo 1.6.7.

  o Latest ISC cron (+ patches and atrun integration).

  o Improved vlan(4) robustness.

  o FreeBSD emulation now recognizes newer FreeBSD ELF binaries.

  o Significant improvements to the pthread library.

  o Many, many man page improvements.

If you'd like to see a list of what has changed between OpenBSD 3.2
and 3.3, look at

        http://www.OpenBSD.org/plus33.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 3.3 FTP/CD-ROM binaries and the actual 3.3
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

        http://www.OpenBSD.org/security.html
and
	http://www.OpenBSD.org/errata.html

Security patch announcements are sent to the security-announce@OpenBSD.org
mailing list.  For information on OpenBSD mailing lists, please see:

	http://www.OpenBSD.org/mail.html

------------------------------------------------------------------------
- CD-ROM SALES ----------------------------------------------------------

OpenBSD 3.3 is also available on CD-ROM.  The 3-CD set costs $40USD
(EUR 45) and is available via mail order and from a number of
contacts around the world.  The set includes a colorful booklet
which carefully explains the installation of OpenBSD.  A new set
of cute little stickers are 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 exclusive audio track,
"Puff the Barbarian."  Lyrics for the song may be found at:
    http://www.OpenBSD.org/lyrics.html#33

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 3.3 CD-ROMs are bootable on the following four platforms:
  o i386
  o macppc
  o sparc
  o sparc64 (UltraSPARC)

(Other platforms must boot from floppy, network, or other method).

For more information on ordering CD-ROMs, see:

        http://www.OpenBSD.org/orders.html

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:

        https://https.OpenBSD.org/cgi-bin/order

or, for European orders:

	https://https.OpenBSD.org/cgi-bin/order.eu

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:

        http://www.OpenBSD.org/goals.html#funding

------------------------------------------------------------------------
- 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:

        https://https.OpenBSD.org/cgi-bin/order

and for Europe: 

	https://https.OpenBSD.org/cgi-bin/order.eu

The OpenBSD 3.3 and OpenSSH t-shirts are available now!

------------------------------------------------------------------------
- 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:

        http://www.OpenBSD.org/ftp.html
        ftp://ftp.OpenBSD.org/pub/OpenBSD/3.3/ftplist

   As of May 1, 2003, the following ftp sites have the 3.3 release:

	ftp://ftp.ca.openbsd.org/pub/OpenBSD/3.3/	Alberta, Canada
	ftp://ftp.usa.openbsd.org/pub/OpenBSD/3.3/	Boulder, CO, USA
	ftp://ftp7.usa.openbsd.org/pub/os/OpenBSD/3.3/	West Lafayette, IN, USA
	ftp://openbsd.wiretapped.net/pub/OpenBSD/3.3/	Sydney, Australia
	ftp://ftp.kd85.com/pub/OpenBSD/3.3/		Ghent, Belgium
	ftp://ftp.calyx.nl/pub/OpenBSD/3.3/		Amsterdam, Netherlands
	ftp://ftp.se.openbsd.org/pub/OpenBSD/3.3/	Stockholm, Sweden
	ftp://ftp.linux.org.tr/pub/OpenBSD/3.3/		Turkey

   Other mirrors will take a day or two to update.

2) Connect to that ftp mirror site and go into the directory
   pub/OpenBSD/3.3/ which contains these files and directories.
   This is a list of what you will see:

	ANNOUNCEMENT   XF4.tar.gz     mac68k/        sparc/
	Changelogs/    alpha/         macppc/        sparc64/
	HARDWARE       ftplist        mvme68k/       src.tar.gz 
	PACKAGES       hp300/         packages/      srcsys.tar.gz 
	PORTS          hppa/          ports.tar.gz   tools/
	README         i386/          root.mail      vax/

   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          INSTALL.os2br  cdrom33.fs     index.txt 
	INSTALL.ata    INSTALL.pt     comp33.tgz     man33.tgz 
	INSTALL.chs    MD5            etc33.tgz      misc33.tgz 
	INSTALL.dbr    base33.tgz     floppy33.fs    xbase33.tgz 
	INSTALL.i386   bsd            floppyB33.fs   xfont33.tgz 
	INSTALL.linux  bsd.rd         floppyC33.fs   xserv33.tgz 
	INSTALL.mbr    cd33.iso       game33.tgz     xshare33.tgz 

   If you are new to OpenBSD, fetch _at least_ the file INSTALL.i386
   and the appropriate floppy*.fs or cd33.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:

        http://www.OpenBSD.org/errata.html

   This is the page where we talk about the mistakes we made while
   creating the 3.3 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/3.3/tools
      directory to do so.

------------------------------------------------------------------------
- XFree86 FOR MOST ARCHITECTURES ---------------------------------------

XFree86 has been integrated more closely into the system.  This
release contains XFree86 4.2.1.  Most of our architectures ship
with XFree86, including sparc, sparc64 and macppc.  During installation,
you can install XFree86 quite easily.  Be sure to try out xdm(1)
and see how we have customized it for OpenBSD.

On the i386 platform a few older X servers are included from XFree86
3.3.6.  These can be used for cards that are not supported by XFree86
4.2.1 or where XFree86 4.2.1 support is buggy.  Please read the
/usr/X11R6/README file for post-installation information.

------------------------------------------------------------------------
- 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 3.3 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 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/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/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/3.3/ directory:

        XF4.tar.gz     ports.tar.gz   src.tar.gz     srcsys.tar.gz

------------------------------------------------------------------------
- THANKS ---------------------------------------------------------------
