OpenBSD 5.8 released

Theo de Raadt-2
OpenBSD 5.8 arrives on the 20th birthday of the OpenBSD project.

October 18, 2015.

We are pleased to announce the official release of OpenBSD 5.8.
This is our 38th release on CD-ROM (and 39th via FTP/HTTP).  We remain
proud of OpenBSD's record of twenty years with only two remote holes in
the default install.

As in our previous releases, 5.8 provides significant improvements,
including new features, in nearly all areas of the system:

 - Improved hardware support, including:
    o New rtwn(4) driver for Realtek RTL8188CE wifi cards.
    o New hpb(4) driver for HyperTransport bridges as found in the IBM
    o The ugold(4) driver now supports TEMPerHUMV1.x temperature and
      humidity sensors.
    o Improved sensor support for the upd(4) driver for USB Power
      Devices (UPS).
    o Support for jumbo frames on re(4) devices using RTL8168C/D/E/F/G
      and RTL8411, including PC Engines APU.
    o re(4) now works with newer devices e.g. RTL8111GU.
    o Partial support has been added for full-speed isochronous devices
      in ehci(4), allowing USB 1.1 audio devices to be used on
      EHCI-only systems in some cases.
    o Improved macppc stability and G5 performances with MP kernels.
    o acpicpu(4) uses ACPI C-state information to reduce power
      consumption of idle CPUs.
    o Kernel supports x86 AVX instructions on CPUs that have them.
    o Avoid assigning low address to PCI BARs, fixing various issues on
      machines whose BIOSes neglect to claim low memory.
    o wscons(4) works with even more odd trackpads.
    o Added pvbus(4) paravirtual device tree root on virtual machines
      that are running on hypervisors.
    o New octdwctwo(4) driver for USB support on OpenBSD/octeon.
    o New amdcf(4) driver for embedded flash on OpenBSD/octeon.
    o Support for RTL8188EU devices was added to the urtwn(4) driver.

 - Removed hardware support:
    o The lmc(4) driver for Lan Media Corporation SSI/T1/DS1/HSSI/DS3
      devices has been removed.
    o The san(4) driver for Sangoma Technologies AFT T1/E1 devices has
      been removed.

 - Generic network stack improvements:
    o MTU of vlan(4) devices can now be set independently from the
      parent interface's MTU.
    o The same network range can now be assigned to multiple
      interfaces, using interface priorities to choose between them.
    o New MPLS pseudowire driver mpw(4).
    o Much preparatory work for MP unlocking of the network stack.

 - Installer improvements:
    o The logic of the 'Allow root ssh login?' question has been
       - The default answer is now 'no'.
       - 'prohibit-password' has been added to the list of possible
    o autoinstall(8) has been extended to allow
       - hostname-mode.conf response file names.
       - response files to be placed in a subdir of the webserver's
         document root.
       - passing a template file to disklabel(8) to automatically
         partition the disk.
    o ntpd(8) is now enabled by default at install time.
    o DUID support has improved enough that new installs now use them
    o Installing sets from CD-ROM has been fixed if more than one
      CD-ROM drive is present.
    o The 'Which CD-ROM contains the install media?' question has been
      removed. Available cdrom devices are now shown directly in the
      'Location of sets?' prompt.

 - Routing daemons and other userland network improvements:
    o Many improvements and simplifications in ldpd(8), including
      configuration reload and support for mpw(4) pseudowire interfaces.
    o bgpd(8) now allows rules to match on the peer AS number.
    o For terminated BGP sessions, bgpctl(8) now displays the number of
      prefixes received on the last session.
    o ospfd(8) now correctly handles carp(4) interfaces in "backup" mode
      at startup.
    o Log messages in bgpd(8) and ospfd(8) have been made more specific.
    o The default Diffie-Hellman group for VPNs configured by
      ipsec.conf(5) has been changed to modp3072.
    o New radiusd(8), Remote Authentication Dial In User Service
      (RADIUS) daemon.

 - Security improvements:
    o sudo in base has been replaced with doas(1), sudo is available as
      a package.
    o file(1) has been replaced with a new modern implementation,
      including sandbox and privilege separation.
    o pax(1) (and tar(1) and cpio(1)) now prevent archive extraction
      from escaping the current directory via symlinks; tar(1) without
      -P option now strips up through any ".." path components.
    o Static PIE support for sparc.
    o Alpha switched to secure PLT.
    o Improved kernel checks of ELF headers.
    o Support for the NX (No-eXecute) bit on i386, resulting in much
      better W^X enforcement in userland for hardware that has this
    o Enforcement of W^X in the kernel address space on i386 when using
      processors with the NX bit.
    o Work started on a new process-containment facility called tame(2).

 - Assorted improvements:
    o The worm(6) now grows at a rate proportional to terminal size.
    o dlclose(3) now unregisters handlers registered by a
      pthread_atfork(3) call from the unloaded libraries.
    o cp(1), mv(1), and pax(1) with the -rw option now preserve
      timestamps with full nanosecond precision.
    o pax(1) now detects failure to decompress an archive when reading
      it and errors out immediately.
    o nm(1) now supports the -D option for displaying the dynamic symbol
    o dump(8) now uses DUIDs in /etc/dumpdates when present and the -U
      option has thus been removed.
    o Corrected kdump(1) reporting of lseek(2) return value on ILP32
      archs and getsockopt/setsockopt(2) level and optname arguments.
      iovec, msghdr, and cmsghdr structures are now dumped.
    o sed(1) -i option added.
    o New, much simpler man.conf(5) configuration file format for
      man(1), apropos(1), and makewhatis(8).
    o When using man(1) with the less(1) pager, support the :t internal
      command to search for definitions of keywords similar to what
      ctags(1) provides.
    o Improvements in checking of numeric option values in many
    o Upgraded to binutils version 2.17 with additional fixes.
    o Improved correctness of poll(2) and poll(2) of O_RDONLY FIFO fds.
    o Restored reporting of closed sockets by netstat(1) and systat(1).
    o fdisk(8) now zeros correct GPT sector at end of disk.
    o fdisk(8) now accepts 'T' sizes for terabytes.
    o fdisk(8) repaired to work on 4K sector disks again.
    o dhcpd(8) now logs correct giaddr and ciaddr information even when
      DHCP relays are present.
    o dhcpd(8) now accommodates Linux and MS clients by not sending
      routers or static routes info when classless static routes are
    o dhcpd(8) and dhclient(8) now accept hostnames beginning with a
    o dhclient(8) no longer rejects leases with addresses overlapping
      existing subnets on other interfaces. Kernel routing logic now
      just works.
    o Improvements to realloc(3) decrease system calls and increase
    o The reaper now tears down dead processes without holding on to the
      kernel lock. This greatly reduces latency and increases
      performance on multi-processor systems.

 - OpenBSD httpd(8):
    o New features:
       - Added support for matching and redirections with Lua
       - Implemented If-Modified-Since for conditional GET or HEAD
         requests (RFC 7232).
       - Added byte-range support for range requests (RFC 7233).
       - Allowing to specify a global or per-location default media
         type instead of application/octet-stream.
       - Added support for HTTP Strict Transport Security (HSTS; RFC
       - Added initial regression test suite based on relayd(8)'s
    o Fixes and improvements:
       - TLS in httpd(8) and relayd(8) now defaults to TLSv1.2-only.
       - Fixed support for large TLS keys or certificate bundles with
         up to 16KB each.
       - Fixed the Content-Length header for files larger than 2 GB on
         32-bit architectures.
       - Fixed translation of CGI environment variables in accordance
         with RFCs 7230 and 3875.
       - Improved memory usage and fixed possible memory exhaustion on
         large file transfers.
       - Added URL-encoding of specific CGI variables before using
         them in the Location header.
       - Prepend files or directories containing ":" with "./" in
         directory indexes as per RFC 3986.
       - Allowing to specify characters like "?" in the Location URI.
       - Various other bug fixes and improvements.

 - OpenSMTPD 5.4.4
    o smtpd(8) reliability and bug fixes.
    o NOTE: Some security risks were discovered and fixed after the
      OpenBSD 5.8 release. See 5.8 errata 004.

 - OpenSSH 7.0:
    o Security:
       - ssh(1): when forwarding X11 connections with
         ForwardX11Trusted=no, connections made after
         ForwardX11Timeout expired could be permitted and no longer
         subject to XSECURITY restrictions because of an ineffective
         timeout check in ssh(1) coupled with "fail open" behaviour in
         the X11 server when clients attempted connections with
         expired credentials. This problem was reported by Jann Horn.
       - ssh-agent(1): fix weakness of agent locking (ssh-add -x) to
         password guessing by implementing an increasing failure
         delay, storing a salted hash of the password rather than the
         password itself and using a timing-safe comparison function
         for verifying unlock attempts. This problem was reported by
         Ryan Castellucci.
       - sshd(8): OpenSSH 6.8 and 6.9 incorrectly set TTYs to be
         world-writable. Local attackers may be able to write
         arbitrary messages to logged-in users, including terminal
         escape sequences.
       - sshd(8): fix circumvention of MaxAuthTries using
         keyboard-interactive authentication. By specifying a long,
         repeating keyboard-interactive "devices" string, an attacker
         could request the same authentication method be tried
         thousands of times in a single pass. The LoginGraceTime
         timeout in sshd(8) and any authentication failure delays
         implemented by the authentication mechanism itself were still
    o Potentially-incompatible changes:
       - Support for the legacy SSH version 1 protocol is disabled by
         default at compile time.
       - Support for the 1024-bit diffie-hellman-group1-sha1 key
         exchange is disabled by default at run-time. It may be
         re-enabled using the instructions at
       - Support for ssh-dss, ssh-dss-cert-* host and user keys is
         disabled by default at run-time. These may be re-enabled
         using the instructions at
       - Support for the legacy v00 cert format has been removed.
       - The default for the sshd_config(5) PermitRootLogin option has
         changed from "yes" to "prohibit-password" (but the OpenBSD
         installer defaults to "no").
       - NOTE: 'PermitRootLogin prohibit-password' is subtly broken in
         the OpenBSD 5.8 / OpenSSH 7.0; see 5.8 errata 001.
    o New/changed features:
       - ssh(1), sshd(8): promote [hidden email] to be
         the default cipher.
       - sshd(8): support admin-specified arguments to
         AuthorizedKeysCommand. (bz#2081)
       - sshd(8): add AuthorizedPrincipalsCommand that allows
         retrieving authorized principals information from a
         subprocess rather than a file.
       - ssh(1), ssh-add(1): support PKCS#11 devices with external PIN
         entry devices. (bz#2240)
       - sshd(8): allow GSSAPI host credential check to be relaxed for
         multihomed hosts via GSSAPIStrictAcceptorCheck option.
       - ssh-keygen(1): support ssh-keygen -lF hostname to search
         known_hosts and print key hashes rather than full keys.
       - ssh-agent(1): add -D flag to leave ssh-agent(1) in foreground
         without enabling debug mode. (bz#2381)
       - ssh_config(5): add PubkeyAcceptedKeyTypes option to control
         which public key types are available for user authentication.
       - sshd_config(5): add HostKeyAlgorithms option to control which
         public key types are offered for host authentications.
       - ssh(1), sshd(8): extend Ciphers, MACs, KexAlgorithms,
         HostKeyAlgorithms, PubkeyAcceptedKeyTypes and
         HostbasedKeyTypes options to allow appending to the default
         set of algorithms instead of replacing it. Options may now be
         prefixed with a + to append to the default, e.g.
    o The following significant bugs have been fixed in this release:
       - ssh(1), sshd(8): deprecate legacy
         SSH2_MSG_KEX_DH_GEX_REQUEST_OLD message and do not try to use
         it against some 3rd-party SSH implementations that use it
         (older PuTTY, WinSCP).
       - Many fixes for problems caused by compile-time deactivation
         of SSH1 support. (including bz#2369)
       - ssh(1), sshd(8): cap DH-GEX group size at 4Kbits for Cisco
         implementations as some would fail when attempting to use
         group sizes greater than 4K. (bz#2209)
       - ssh(1): fix out-of-bound read in EscapeChar configuration
         option parsing. (bz#2396)
       - sshd(8): fix application of PermitTunnel, LoginGraceTime,
         AuthenticationMethods and StreamLocalBindMask options in
         Match blocks.
       - ssh(1), sshd(8): improve disconnection message on TCP reset.
       - ssh(1): remove failed remote forwards established by
         multiplexing from the list of active forwards. (bz#2363)
       - sshd(8): make parsing of authorized_keys "environment="
         options independent of PermitUserEnv being enabled. (bz#2329)
       - sshd(8): fix post-auth crash with permitopen=none. (bz#2355)
       - ssh(1), ssh-add(1), ssh-keygen(1): allow new-format private
         keys to be encrypted with AEAD ciphers. (bz#2366)
       - ssh(1): allow ListenAddress, Port and AddressFamily
         configuration options to appear in any order. (bz#86)
       - sshd(8): check for and reject missing arguments for
         VersionAddendum and ForceCommand. (bz#2281)
       - ssh(1), sshd(8): don't treat unknown certificate extensions
         as fatal. (bz#2387)
       - ssh-keygen(1): make stdout and stderr output consistent.
       - ssh(1): mention missing DISPLAY environment in debug log when
         X11 forwarding requested. (bz#1682)
       - sshd(8): correctly record login when UseLogin is set.
       - sshd(8): add some missing options to sshd -T output and fix
         output of VersionAddendum and HostCertificate. (bz#2346)
       - Document and improve consistency of options that accept a
         "none" argument: TrustedUserCAKeys, RevokedKeys (bz#2382),
         AuthorizedPrincipalsFile (bz#2288).
       - ssh(1): include remote username in debug output. (bz#2368)
       - sshd(8): avoid compatibility problem with some versions of
         Tera Term, which would crash when they received the hostkeys
         notification message ([hidden email]).
       - sshd(8): mention ssh-keygen -E as useful when comparing
         legacy MD5 host key fingerprints. (bz#2332)
       - ssh(1): clarify pseudo-terminal request behaviour and use
         make manual language consistent. (bz#1716)
       - ssh(1): document that the TERM environment variable is not
         subject to SendEnv and AcceptEnv. (bz#2386)
       - ssh(1), sshd(8): add compatability workarounds for Cisco and
         more PuTTY versions. (bz#2424)
       - Fix some omissions and errors in the PROTOCOL and PROTCOL.mux
         documentation relating to Unix domain socket forwarding.
         (bz#2421, bz#2422)
       - ssh(1): Improve the ssh(1) manual page to include a better
         desciption of Unix domain socket forwarding. (bz#2423)
       - ssh(1), ssh-agent(1): skip uninitialised PKCS#11 slots,
         fixing failures to load keys when they are present. (bz#2427)
       - ssh(1), ssh-agent(1): do not ignore PKCS#11 hosted keys that
         wth empty CKA_ID. (bz#2429)
       - sshd(8): clarify documentation for UseDNS option. (bz#2045)

 - LibreSSL
    o User-visible features:
       - Reject all server DH keys smaller than 1024 bits.
       - Multiple CVEs fixed including CVE-2015-0207, CVE-2015-0209,
         CVE-2015-0286, CVE-2015-0287, CVE-2015-0288, CVE-2015-0289,
         CVE-2015-1788, CVE-2015-1789, CVE-2015-1792.
       - Protocol parsing conversions to BoringSSL's CRYPTO ByteString
         (CBS) API.
       - Added EC_curve_nid2nist and EC_curve_nist2nid from OpenSSL.
       - Removed Dynamic Engine support.
       - Removed MDC-2DES support.
       - Switched openssl dhparam default from 512 to 2048 bits.
       - Fixed openssl pkeyutl -verify to exit with a 0 on success.
       - Fixed dozens of Coverity issues including dead code, memory
         leaks, logic errors and more.
       - Ensure that openssl(1) restores terminal echo state after
         reading a password.
       - Incorporated fix for OpenSSL issue #3683.
       - Removed SSLv3 support from openssl(1).
       - Modified tls_write in libtls to allow partial writes,
         clarified with examples in the documentation.
       - Removed RSAX engine.
       - Tested SSLv3 removal with the OpenBSD ports tree and found
         several applications that were not ready to build without
         SSLv3 yet. For now, building a program that intentionally
         uses SSLv3 will result in a linker warning.
       - Added TLS_method, TLS_client_method and TLS_server_method as
         a replacement for the SSLv23_*method calls.
       - Default cert.pem, openssl.cnf, and x509v3.cnf files are now
         installed under $sysconfdir/ssl or the directory specified by
         --with-openssldir. Previous versions of LibreSSL left these
       - NOTE: LibreSSL 2.2.2 in OpenBSD 5.8 incorrectly handles
         ClientHello messages that do not include TLS extensions,
         resulting in such handshakes being aborted. see 5.8 errata
    o Code improvements:
       - Fix incorrect comparison function in openssl(1) certhash
         command. Thanks to Christian Neukirchen / Void Linux.
       - Removal of OPENSSL_issetugid and all library getenv calls.
         Applications can and should no longer rely on environment
         variables for changing library behavior. OPENSSL_CONF and
         SSLEAY_CONF are still supported with the openssl(1) command,
         but note that $ENV:: is no longer supported in .cnf files.
       - libtls API and documentation additions.
       - Various bug fixes and simplifications to libssl and
       - Reworked openssl(1) option handling.
       - LibreSSL version define LIBRESSL_VERSION_NUMBER will now be
         bumped for each portable release.
       - Removed workarounds for TLS client padding bugs.
       - Removed IE 6 SSLv3 workarounds.
       - --with-enginesdir is removed as a configuration parameter.

 - Syslogd:
    o OpenBSD syslogd(8) can bind to explicitly given UDP or TCP sockets
      to receive messages. TCP streams are accepted with the octet
      counting or the non transparent framing method.
    o Blocks in syslog.conf(5) started with +host process messages
      created by certain hosts specifically.
    o Handle situations when the file descriptor limit is exhausted
    o Since libtls handles short writes smarter, syslogd(8) can use the
      complete output buffer to save messages, coping with longer TLS
      server down times without losing messages.

 - Ports and packages:
   Many pre-built packages for each architecture:
    o alpha:    7093                  o powerpc:  8114
    o amd64:    8866                  o sh:       133

If you'd like to see a list of what has changed between OpenBSD 5.7
and 5.8, look at

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 5.8 HTTP/CD-ROM binaries and the actual 5.8
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

- MAILING LISTS --------------------------------------------------------

Mailing lists are an important means of communication among users and
developers of OpenBSD.  For information on OpenBSD mailing lists, please

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

OpenBSD 5.8 is also available on CD-ROM.  The 3-CD set costs 44 EUR and
is available via web order worldwide.

The CD 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 HTTP mirror sites do not support STP, the Sticker
Transfer Protocol).  As an added bonus, the second CD contains audio tracks
for four songs: "20 years ago today", "Fanza", "So much better", and
"A Year in the Life".  MP3 and OGG versions of the audio tracks can be
found on the first CD.

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 5.8 CD-ROMs are bootable on the following platforms:

  o i386
  o amd64
  o macppc
  o sparc64

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

For more information on ordering CD-ROMs, see:

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:

- OPENBSD FOUNDATION ---------------------------------------------------

For those unable to make their contributions as straightforward gifts,
the OpenBSD Foundation ( is a Canadian
not-for-profit corporation that can accept larger contributions and
issue receipts.  In some situations, their receipt may qualify as a
business expense write-off, so this is certainly a consideration for
some organizations or businesses.  There may also be exposure benefits
since the Foundation may be interested in participating in press releases.
In turn, the Foundation then uses these contributions to assist OpenBSD's
infrastructure needs.  Contact the foundation directors at

- T-SHIRT SALES --------------------------------------------------------

The OpenBSD distribution company also sells T-shirts with new and old
designs and other merchandise, available from its web ordering system.

- HTTP INSTALLS --------------------------------------------------------

If you choose not to buy an OpenBSD CD-ROM, OpenBSD can be easily
installed via HTTP downloads.  Typically you need a single
small piece of boot media (e.g., a USB flash drive) 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 HTTP.  With the CD-ROMs,
the necessary documentation is easier to find.

1) Read either of the following two files for a list of HTTP
   mirrors which provide OpenBSD, then choose one near you:

   As of October 18, 2015, the following HTTP mirror sites have the 5.8 release:      Stockholm, Sweden        Oldenburg, Germany      Zurich, Switzerland      Paris, France     Vienna, Austria    Brisbane, Australia     CO, USA    CA, USA         TX, USA

        The release is also available at the master site:          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 HTTP mirror site and go into the directory
   pub/OpenBSD/5.8/ which contains these files and directories.
   This is a list of what you will see:

        ANNOUNCEMENT     alpha/           luna88k/         sparc/
        Changelogs/      amd64/           macppc/          sparc64/
        HARDWARE         armish/          octeon/          src.tar.gz
        PACKAGES         armv7/           packages/        sys.tar.gz
        PORTS            hppa/            ports.tar.gz     tools/
        README           i386/            root.mail        vax/
        SHA256           landisk/         sgi/             xenocara.tar.gz
        SHA256.sig       loongson/        socppc/          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, amd64.  This is a list of what you will see:

        INSTALL.amd64   bsd.rd*         game58.tgz      pxeboot*
        SHA256          cd58.iso        index.txt       xbase58.tgz
        SHA256.sig      cdboot*         install58.fs    xfont58.tgz
        base58.tgz      cdbr*           install58.iso   xserv58.tgz
        bsd*            comp58.tgz      man58.tgz       xshare58.tgz*         floppy58.fs     miniroot58.fs
   If you are new to OpenBSD, fetch _at least_ the file INSTALL.amd64
   and install58.iso.  The install58.iso file (roughly 290MB in size)
   is a one-step ISO-format install CD image which contains the various
   *.tgz files so you do not need to fetch them separately.

   If you prefer to use a USB flash drive, fetch install58.fs and
   follow the instructions in INSTALL.amd64.

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.amd64.  INSTALL.amd64 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 5.8 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.

- X.ORG FOR MOST ARCHITECTURES -----------------------------------------

X.Org has been integrated more closely into the system.  This release
contains X.Org 7.7.  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 5.8 ports collection
is included on the 3-CD set.  Please see the PORTS file for more

Note: a few popular ports, e.g., NSD, Unbound, 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 ------------------------------------------------------

A large number of binary packages are provided.  Please see the PACKAGES
file ( for more details.

- SYSTEM SOURCE CODE ---------------------------------------------------

The CD-ROMs contain source code for all the subsystems explained
above, and the README (
file explains how to deal with these source files.  For those who
are doing an HTTP install, the source code for all four subsystems
can be found in the pub/OpenBSD/5.8/ directory:

        xenocara.tar.gz     ports.tar.gz   src.tar.gz     sys.tar.gz

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 5.8 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.
