</ul>
<p>
<li>Generic network stack improvements:
<ul>
<li>MTU of <a href="https://man.openbsd.org/vlan.4">vlan(4)</a> devices can now be set independently from the parent interface's MTU.
<li>The same network range can now be assigned to multiple interfaces, using interface priorities to choose between them.
<li>New MPLS pseudowire driver <a href="https://man.openbsd.org/mpw.4">mpw(4)</a>.
<li>Much preparatory work for MP unlocking of the network stack.
</ul>
<p>
<li>Installer improvements:
<ul>
<li>The logic of the 'Allow root ssh login?' question has been changed.
<ul>
<li>The default answer is now 'no'.

</ul>
<li>Fixes and improvements:
<ul>
<li>TLS in <a href="https://man.openbsd.org/OpenBSD-current/man8/httpd.8">httpd(8)</a> and <a href="https://man.openbsd.org/OpenBSD-current/man8/relayd.8">relayd(8)</a> now defaults to TLSv1.2-only.

<p>
<li>OpenSMTPD 5.4.4
<ul>
<li><a href="https://man.openbsd.org/smtpd.8">smtpd(8)</a> reliability and bug fixes.
<li><b>NOTE: Some security risks were discovered and fixed after the
OpenBSD 5.8 release.
See <a href="errata58.html#004_smtpd">5.8 errata 004</a>.</b>
</ul>
<p>
<li>OpenSSH 7.0
<ul>
<li>Security:
<ul>
<li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
when forwarding X11 connections with <code>ForwardX11Trusted=no</code>,
connections made after <code>ForwardX11Timeout</code> expired could be
permitted and no longer subject to XSECURITY restrictions because of
an ineffective timeout check in
<a href="https://man.openbsd.org/ssh.1">ssh(1)</a>
coupled with "fail open" behaviour in the X11 server when clients
attempted connections with expired credentials.
This problem was reported by Jann Horn.
<li><a href="https://man.openbsd.org/ssh-agent.1">ssh-agent(1)</a>:
fix weakness of agent locking (<code>ssh-add -x</code>) 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.
<li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
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.
<li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
fix circumvention of <code>MaxAuthTries</code> 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
<code>LoginGraceTime</code> timeout in
<a href="https://man.openbsd.org/sshd.8">sshd(8)</a>
and any authentication failure delays implemented by the authentication
mechanism itself were still applied.
</ul>
<li>Potentially-incompatible changes:
<ul>
<li>Support for the legacy <i>SSH version 1 protocol</i> is disabled by
default at compile time.
<li>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 <code>https://www.openssh.com/legacy.html</code>.
<li>Support for <code>ssh-dss</code>, <code>ssh-dss-cert-*</code> <i>host</i>
and <i>user</i> keys is disabled by default at run-time. These may
be re-enabled using the instructions at
<code>https://www.openssh.com/legacy.html</code>.
<li>Support for the legacy <i>v00 cert format</i> has been removed.
<li>The default for the
<a href="https://man.openbsd.org/sshd_config.5">sshd_config(5)</a>
<code>PermitRootLogin</code> option has changed from "yes" to
"prohibit-password" (but the OpenBSD installer defaults to "no").
<li><b>NOTE: 'PermitRootLogin prohibit-password' is subtly broken
in the OpenBSD 5.8 / OpenSSH 7.0. See
<a href="errata58.html#001_sshd">5.8 errata 001</a>.</b>

<p>
<li>LibreSSL
<ul>
<li>User-visible features:
<ul>
<li>Reject all <i>server DH keys</i> smaller than 1024 bits.
<li>Multiple CVEs fixed including CVE-2015-0207, CVE-2015-0209,
CVE-2015-0286, CVE-2015-0287, CVE-2015-0288, CVE-2015-0289,

<li>Protocol parsing conversions to BoringSSL's <i>CRYPTO ByteString</i>
(CBS) API.
<li>Added <code>EC_curve_nid2nist</code> and <code>EC_curve_nist2nid</code>
from OpenSSL.
<li>Removed Dynamic Engine support.
<li>Removed MDC-2DES support.
<li>Switched <code>openssl dhparam</code> default from 512 to 2048 bits.
<li>Fixed <code>openssl pkeyutl -verify</code> to exit with a 0 on success.
<li>Fixed dozens of Coverity issues including dead code, memory leaks,
logic errors and more.
<li>Ensure that
<a href="https://man.openbsd.org/openssl.1">openssl(1)</a>
restores terminal echo state after reading a password.
<li>Incorporated fix for OpenSSL issue #3683.
<li>Removed SSLv3 support from
<a href="https://man.openbsd.org/openssl.1">openssl(1)</a>.
<li>Modified <code>tls_write</code> in <code>libtls</code> to allow partial
writes, clarified with examples in the documentation.
<li>Removed RSAX engine.
<li>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.
<li>Added <code>TLS_method</code>, <code>TLS_client_method</code> and
<code>TLS_server_method</code> as a replacement for the
<code>SSLv23_*method</code> calls.
<li>Default <code>cert.pem</code>, <code>openssl.cnf</code>, and
<code>x509v3.cnf</code> files are now installed under
<code>$sysconfdir/ssl</code> or the directory specified by
<code>--with-openssldir</code>. Previous versions of LibreSSL left
these empty.
<li><b>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
<a href="errata58.html#002_sslhello">5.8 errata 002</a>.</b>
<li><b>NOTE: An issue (likely denial of service) was found in LibreSSL;
See <a href="errata58.html#007_obj2txt">5.8 errata 007</a>.</b>
</ul>
<li>Code improvements:
<ul>
<li>Fix incorrect comparison function in <a href="https://man.openbsd.org/openssl.1">openssl(1)</a> certhash command.
Thanks to Christian Neukirchen / Void Linux.
<li>Removal of <code>OPENSSL_issetugid</code> and all library getenv calls.
Applications can and should no longer rely on environment variables
for changing library behavior.
<code>OPENSSL_CONF</code> and <code>SSLEAY_CONF</code> are still supported with the
<a href="https://man.openbsd.org/openssl.1">openssl(1)</a>
command, but note that $ENV:: is no longer supported in .cnf files.
<li><code>libtls</code> API and documentation additions.
<li>Various bug fixes and simplifications to <code>libssl</code> and
<code>libcrypto</code>.
<li>Reworked
<a href="https://man.openbsd.org/openssl.1">openssl(1)</a>
option handling.
<li>LibreSSL version define <code>LIBRESSL_VERSION_NUMBER</code> will now
be bumped for each portable release.
<li>Removed workarounds for TLS client padding bugs.
<li>Removed IE 6 SSLv3 workarounds.
<li><code>--with-enginesdir</code> is removed as a configuration parameter.
</ul>
</ul>
<p>
<li>Syslogd:
<ul>
<li>OpenBSD
<a href="https://man.openbsd.org/syslogd.8">syslogd(8)</a>
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.
<li>Blocks in
<a href="https://man.openbsd.org/syslog.conf.5">syslog.conf(5)</a>
started with <code>+host</code> process messages created by
certain hosts specifically.
<li>Handle situations when the file descriptor limit is exhausted
gracefully.
<li>Since libtls handles short writes smarter, <a href="https://man.openbsd.org/syslogd.8">syslogd(8)</a> can use the
complete output buffer to save messages, coping with
longer TLS server down times without losing messages.

<h3>How to install</h3>
<p>
Following this are the instructions which you would have on a piece of
paper if you had purchased a CDROM set instead of doing an alternate
form of install. The instructions for doing an HTTP (or other style
of) install are very similar; the CDROM instructions are left intact
so that you can see how much easier it would have been if you had
purchased a CDROM instead.

<section id=quickinstall>
<p>
Quick installer information for people familiar with OpenBSD, and the
use of the "disklabel -E" command. If you are at all confused when
installing OpenBSD, read the relevant INSTALL.* file as listed above!
<h3>OpenBSD/i386:</h3>
<p>
The OpenBSD/i386 release is on CD1.
Boot from the CD to begin the install - you may need to adjust
your BIOS options first.
<p>
If your machine can boot from USB, you can write <i>install58.fs</i> or
<i>miniroot58.fs</i> to a USB stick and boot from it.
<p>
If you can't boot from a CD, floppy disk, or USB,
you can install across the network using PXE as described in
the included INSTALL.i386 document.
<p>
If you are planning on dual booting OpenBSD with another OS, you will need to
read INSTALL.i386.
<h3>OpenBSD/amd64:</h3>
<p>
The OpenBSD/amd64 release is on CD2.
Boot from the CD to begin the install - you may need to adjust
your BIOS options first.
<p>
If your machine can boot from USB, you can write <i>install58.fs</i> or
<i>miniroot58.fs</i> to a USB stick and boot from it.
<p>
If you can't boot from a CD, floppy disk, or USB,
you can install across the network using PXE as described in the included
INSTALL.amd64 document.
<p>
If you are planning to dual boot OpenBSD with another OS, you will need to
read INSTALL.amd64.
<h3>OpenBSD/macppc:</h3>
<p>
Burn the image from a mirror site to a CDROM, and power on your machine
while holding down the <i>C</i> key until the display turns on and
shows <i>OpenBSD/macppc boot</i>.
<p>
Alternatively, at the Open Firmware prompt, enter <i>boot cd:,ofwboot
/5.8/macppc/bsd.rd</i>
<h3>OpenBSD/sparc64:</h3>
<p>
Put CD3 in your CDROM drive and type <i>boot cdrom</i>.
<p>
If this doesn't work, or if you don't have a CDROM drive, you can write
<i>CD3:5.8/sparc64/floppy58.fs</i> or <i>CD3:5.8/sparc64/floppyB58.fs</i>
(depending on your machine) to a floppy and boot it with <i>boot
floppy</i>. Refer to INSTALL.sparc64 for details.
<p>
Make sure you use a properly formatted floppy with NO BAD BLOCKS or your install
will most likely fail.
<p>
You can also write <i>CD3:5.8/sparc64/miniroot58.fs</i> to the swap partition on
the disk and boot with <i>boot disk:b</i>.
<p>
If nothing works, you can boot over the network as described in INSTALL.sparc64.
<h3>OpenBSD/alpha:</h3>
<p>
Write <i>5.8/alpha/floppy58.fs</i> or
<i>5.8/alpha/floppyB58.fs</i> (depending on your machine) to a diskette and
enter <i>boot dva0</i>. Refer to INSTALL.alpha for more details.
<p>
Make sure you use a properly formatted floppy with NO BAD BLOCKS or your install
will most likely fail.
<h3>OpenBSD/armish:</h3>
<p>
After connecting a serial port, Thecus can boot directly from the network
either tftp or http. Configure the network using fconfig, reset,
then load bsd.rd, see INSTALL.armish for specific details.
IOData HDL-G can only boot from an EXT-2 partition. Boot into linux
and copy 'boot' and bsd.rd into the first partition on wd0 (hda1)
then load and run bsd.rd, preserving the wd0i (hda1) ext2fs partition.
More details are available in INSTALL.armish.
<h3>OpenBSD/hppa:</h3>
<p>
Boot over the network by following the instructions in INSTALL.hppa or the
<a href="hppa.html#install">hppa platform page</a>.
<h3>OpenBSD/landisk:</h3>
<p>
Write <i>miniroot58.fs</i> to the start of the CF
or disk, and boot normally.
<h3>OpenBSD/loongson:</h3>
<p>
Write <i>miniroot58.fs</i> to a USB stick and boot bsd.rd from it
or boot bsd.rd via tftp.
Refer to the instructions in INSTALL.loongson for more details.
<h3>OpenBSD/luna88k:</h3>
<p>
Copy 'boot' and 'bsd.rd' to a Mach or UniOS partition, and boot the bootloader
from the PROM, and then bsd.rd from the bootloader.
Refer to the instructions in INSTALL.luna88k for more details.
<h3>OpenBSD/octeon:</h3>
<p>
After connecting a serial port, boot bsd.rd over the network via DHCP/tftp.
Refer to the instructions in INSTALL.octeon for more details.
<h3>OpenBSD/sgi:</h3>
<p>
To install, burn cd58.iso on a CD-R, put it in the CD drive of your
machine and select <i>Install System Software</i> from the System Maintenance
menu. Indigo/Indy/Indigo2 (R4000) systems will not boot automatically from
CD-ROM, and need a proper invocation from the PROM prompt.
Refer to the instructions in INSTALL.sgi for more details.
<p>
If your machine doesn't have a CD drive, you can setup a DHCP/tftp network
server, and boot using "bootp()/bsd.rd.IP##" using the kernel matching your
system type. Refer to the instructions in INSTALL.sgi for more details.
<h3>OpenBSD/socppc:</h3>
<p>
After connecting a serial port, boot over the network via DHCP/tftp.
Refer to the instructions in INSTALL.socppc for more details.
<h3>OpenBSD/sparc:</h3>
<p>
Boot from one of the provided install ISO images, using one of the two
commands listed below, depending on the version of your ROM.
<blockquote><pre>
ok <kbd>boot cdrom 5.8/sparc/bsd.rd</kbd>
or
> <kbd>b sd(0,6,0)5.8/sparc/bsd.rd</kbd>
</pre></blockquote>
<p>
If your SPARC system does not have a CD drive, you can alternatively boot from floppy.
To do so you need to write <i>floppy58.fs</i> to a floppy.
For more information see <a href="faq/faq4.html#MkFlop">this page</a>.
To boot from the floppy use one of the two commands listed below,
depending on the version of your ROM.
<blockquote><pre>
ok <kbd>boot floppy</kbd>
or
> <kbd>b fd()</kbd>
</pre></blockquote>
<p>
Make sure you use a properly formatted floppy with NO BAD BLOCKS or your install
will most likely fail.
<p>
If your SPARC system doesn't have a floppy drive nor a CD drive, you can either
setup a bootable tape, or install via network, as told in the
INSTALL.sparc file.
<h3>OpenBSD/vax:</h3>
<p>
Boot over the network via mopbooting as described in INSTALL.vax.
<h3>OpenBSD/zaurus:</h3>
<p>
Using the Linux built-in graphical ipkg installer, install the
openbsd58_arm.ipk package. Reboot, then run it. Read INSTALL.zaurus
for a few important details.

<h3>How to upgrade</h3>
<p>
If you already have an OpenBSD 5.7 system, and do not want to reinstall,
upgrade instructions and advice can be found in the
<a href="faq/upgrade58.html">Upgrade Guide</a>.
</section>
<hr>
<section id=sourcecode>
<h3>Notes about the source code</h3>
<p>
<code>src.tar.gz</code> contains a source archive starting at <code>/usr/src</code>.
This file contains everything you need except for the kernel sources, which are
in a separate archive. To extract:
<blockquote><pre>
# <kbd>mkdir -p /usr/src</kbd>
# <kbd>cd /usr/src</kbd>
# <kbd>tar xvfz /tmp/src.tar.gz</kbd>
</pre></blockquote>
<p>
<code>sys.tar.gz</code> contains a source archive starting at <code>/usr/src/sys</code>.
This file contains all the kernel sources you need to rebuild kernels.
To extract:
<blockquote><pre>
# <kbd>mkdir -p /usr/src/sys</kbd>
# <kbd>cd /usr/src</kbd>
# <kbd>tar xvfz /tmp/sys.tar.gz</kbd>
</pre></blockquote>
<p>
Both of these trees are a regular CVS checkout. Using these trees it
is possible to get a head-start on using the anoncvs servers as
described <a href="anoncvs.html">here</a>.
Using these files
results in a much faster initial CVS update than you could expect from
a fresh checkout of the full OpenBSD source tree.
</section>
<hr>
<section id=ports>
<h3>Ports Tree</h3>
<p>
A ports tree archive is also provided. To extract:
<blockquote><pre>
# <kbd>cd /usr</kbd>
# <kbd>tar xvfz /tmp/ports.tar.gz</kbd>
</pre></blockquote>
<p>
Go read the <a href="faq/ports/index.html">ports</a> page
if you know nothing about ports
at this point. This text is not a manual of how to use ports.
Rather, it is a set of notes meant to kickstart the user on the
OpenBSD ports system.
<p>
The <i>ports/</i> directory represents a CVS (see the manpage for
<a href="https://man.openbsd.org/cvs.1">cvs(1)</a> if
you aren't familiar with CVS) checkout of our ports. As with our complete
source tree, our ports tree is available via
<a href="anoncvs.html">AnonCVS</a>.
So, in order to keep up to date with the -stable branch, you must make
the <i>ports/</i> tree available on a read-write medium and update the tree
with a command like:
<blockquote><pre>
# <kbd>cd /usr/ports</kbd>
# <kbd>cvs -d [email protected]:/cvs update -Pd -rOPENBSD_5_8</kbd>
</pre></blockquote>
<p>
[Of course, you must replace the server name here with a nearby anoncvs
server.]
<p>
Note that most ports are available as packages on our mirrors. Updated
ports for the 5.8 release will be made available if problems arise.
<p>
If you're interested in seeing a port added, would like to help out, or just
would like to know more, the mailing list
<a href="mail.html">[email protected]</a> is a good place to know.
