<h3>What's New</h3>
|
|
<p>
|
|
This is a partial list of new features and systems included in OpenBSD 5.6.
|
|
For a comprehensive list, see the <a href="plus56.html">changelog</a> leading
|
|
to 5.6.
|
|
|
|
<ul>
|
|
<li>LibreSSL
|
|
<ul>
|
|
<li>This release forks OpenSSL into
|
|
<a href="https://www.libressl.org">LibreSSL</a>, a version of the TLS/crypto
|
|
stack with goals of modernizing the codebase, improving security, and
|
|
applying best practice development processes.
|
|
<li>No support for legacy MacOS, Netware, OS/2, VMS and Windows platforms,
|
|
as well as antique compilers.
|
|
<li>Removal of the IBM 4758, Broadcom ubsec, Sureware, Nuron, GOST, GMP,
|
|
CSwift, CHIL, CAPI, Atalla and AEP engines, either because the hardware is
|
|
irrelevant, or because they require external non-free libraries to work.
|
|
<li>No support for FIPS-140 compliance.
|
|
<li>No EBCDIC support.
|
|
<li>No support for big-endian i386 and amd64 platforms.
|
|
<li>Use standard routines from the C library (malloc, strdup, snprintf...)
|
|
instead of rolling our own, sometimes badly.
|
|
<li>Remove the old OpenSSL PRNG, and rely upon arc4random_buf from libc for
|
|
all the entropy needs.
|
|
<li>Remove the MD2 and SEED algorithms.

|
|
<li>Added <a href="https://man.openbsd.org/OpenBSD-current/man3/reallocarray.3">reallocarray(3)</a>,

<a href="https://man.openbsd.org/OpenBSD-current/man3/warnc.3">warnc(3)</a> and
|
|
<a href="https://man.openbsd.org/OpenBSD-current/man3/vwarnc.3">vwarnc(3)</a>.
|
|
<li>Faster hibernate/unhibernate performance on amd64 and i386 platforms.
|
|
<li>Support hibernating to <a href="https://man.openbsd.org/OpenBSD-current/man4/softraid.4">softraid(4)</a> crypto volumes.
|
|
<li>Improved performance of <a href="https://man.openbsd.org/OpenBSD-current/man3/seekdir.3">seekdir(3)</a> to start of current buffer.
|
|
<li>Added <endian.h> per the revision of the POSIX spec in progress.
|
|
<li>Apache has been removed.
|
|
<li>Read support for ext4 filesystems.
|
|
<li>Reworked mplocks as ticket locks instead of spinlocks on amd64, i386, and sparc64. This provides fairer access to the kernel lock between logical CPUs, especially in multi socket systems.
|
|
</ul>
|
|
<p>
|
|
|
|
<li>OpenSSH 6.7
|
|
<ul>
|
|
<li>Potentially-incompatible changes:
|
|
<ul>
|
|
<li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
|
|
The default set of ciphers and <i>MAC</i>s has been altered to remove
|
|
unsafe algorithms. In particular, <i>CBC ciphers</i> and
|
|
<i>arcfour*</i> are disabled by default.
|
|
<li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
|
|
Support for <i>tcpwrappers</i>/<i>libwrap</i> has been removed.
|
|
<li>OpenSSH 6.5 and 6.6 have a bug that causes ~0.2% of connections
|
|
using the "curve25519-sha256@libssh.org" <i>KEX exchange method</i>
|
|
to fail when connecting with something that implements the
|
|
specification correctly. OpenSSH 6.7 disables this KEX method when
|
|
speaking to one of the affected versions.
|
|
</ul>
|
|
<li>New/changed features:
|
|
<ul>
|
|
<li>Major internal refactoring to begin to make part of OpenSSH usable
|
|
as a library. So far the wire parsing, key handling and KRL code
|
|
has been refactored. Please note that we do not consider the API
|
|
stable yet, nor do we offer the library in separable form.
|
|
<li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>,
|
|
<a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
|
|
Add support for <i>Unix domain socket</i> forwarding. A remote TCP
|
|
port may be forwarded to a local Unix domain socket and vice versa or
|
|
both ends may be a Unix domain socket.
|
|
<li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>,
|
|
<a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
|
|
Add support for <i>SSHFP DNS records</i> for <i>Ed2551</i>9 key types.
|
|
<li><a href="https://man.openbsd.org/sftp.1">sftp(1)</a>:
|
|
Allow resumption of interrupted uploads.
|
|
<li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
|
|
When rekeying, skip file/DNS lookups of the hostkey if it is the same
|
|
as the one sent during initial key exchange. (bz#2154)
|
|
<li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
|
|
Allow explicit ::1 and 127.0.0.1 forwarding bind addresses when
|
|
<code>GatewayPorts=no</code>; allows client to choose address family.
|
|
(bz#2222)
|
|
<li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
|
|
Add a
|
|
<a href="https://man.openbsd.org/sshd_config.5">sshd_config(5)</a>
|
|
<code>PermitUserRC</code> option to control whether <code>~/.ssh/rc</code> is
|
|
executed, mirroring the <code>no-user-rc</code> authorized_keys option.
|
|
(bz#2160)
|
|
<li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
|
|
Add a %C escape sequence for <code>LocalCommand</code> and
|
|
<code>ControlPath</code> that expands to a unique identifier based on a
|
|
hash of the tuple of (local host, remote user, hostname, port). Helps
|
|
avoid exceeding miserly pathname limits for Unix domain sockets in
|
|
multiplexing control paths. (bz#2220)
|
|
<li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
|
|
Make the "Too many authentication failures" message include the user,
|
|
source address, port and protocol in a format similar to the
|
|
authentication success/failure messages. (bz#2199)
|
|
<li>Added <i>unit</i> and <i>fuzz</i> tests for refactored code.
|
|
</ul>
|
|
<li>The following significant bugs have been fixed in this release:
|
|
<ul>
|
|
<li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
|
|
Fix remote forwarding with same listen port but different listen
|
|
address.
|
|
<li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
|
|
Fix inverted test that caused <i>PKCS#11</i> keys that were explicitly
|
|
listed in
|
|
<a href="https://man.openbsd.org/ssh_config.5">ssh_config(5)</a>
|
|
or on the commandline not to be preferred.
|
|
<li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
|
|
Fix bug in KRL generation: multiple consecutive revoked certificate
|
|
serial number ranges could be serialised to an invalid format.
|
|
Readers of a broken KRL caused by this bug will fail closed, so no
|
|
should-have-been-revoked key will be accepted.
|
|
<li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
|
|
Reflect stdio-forward ("<code>ssh -W host:port ...</code>") failures in
|
|
exit status. Previously we were always returning 0. (bz#2255)
|
|
<li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>,
|
|
<a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
|
|
Make Ed25519 keys' title fit properly in the randomart border.
|
|
(bz#2247)
|
|
<li><a href="https://man.openbsd.org/ssh-agent.1">ssh-agent(1)</a>:
|
|
Only cleanup agent socket in the main agent process and not in any
|
|
subprocesses it may have started (e.g. forked askpass). Fixes agent
|
|
sockets being zapped when askpass processes <i>fatal()</i>. (bz#2236)
|
|
<li><a href="https://man.openbsd.org/ssh-add.1">ssh-add(1)</a>:
|
|
Make stdout line-buffered; saves partial output getting lost when
|
|
<a href="https://man.openbsd.org/ssh-add.1">ssh-add(1)</a>
|
|
<i>fatal()</i>s part-way through (e.g. when listing keys from an
|
|
agent that supports key types that
|
|
<a href="https://man.openbsd.org/ssh-add.1">ssh-add(1)</a>
|
|
doesn't). (bz#2234)
|
|
<li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
|
|
When hashing or removing hosts, don't choke on "@revoked" markers and
|
|
don't remove "@cert-authority" markers. (bz#2241)
|
|
<li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
|
|
Don't fatal when hostname canonicalisation fails and a
|
|
<code>ProxyCommand</code> is in use; continue and allow the
|
|
<code>ProxyCommand</code> to connect anyway (e.g. to a host with a name
|
|
outside the DNS behind a bastion).
|
|
<li><a href="https://man.openbsd.org/scp.1">scp(1)</a>:
|
|
When copying local->remote fails during read, don't send uninitialised
|
|
heap to the remote end.
|
|
<li><a href="https://man.openbsd.org/sftp.1">sftp(1)</a>:
|
|
Fix fatal "el_insertstr failed" errors when tab-completing filenames
|
|
with a single quote char somewhere in the string. (bz#2238)
|
|
<li><a href="https://man.openbsd.org/ssh-keyscan.1">ssh-keyscan(1)</a>:
|
|
Scan for Ed25519 keys by default.
|
|
<li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
|
|
When using <code>VerifyHostKeyDNS</code> with a DNSSEC resolver,
|
|
down-convert any certificate keys to plain keys and attempt SSHFP
|
|
resolution. Prevents a server from skipping SSHFP lookup and forcing
|
|
a new-hostkey dialog by offering only certificate keys.
|
|
<li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
|
|
Avoid crash at exit via NULL pointer reference. (bz#2225)
|
|
<li>Fix some strict-alignment errors.
|
|
</ul>
|
|

<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 FTP (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.
|
|
<p>
|
|
|
|
<hr>
|
|
Please refer to the following files on the three CDROMs or FTP mirror for
|
|

<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>
|
|
Play with your BIOS options to enable booting from a CD. The OpenBSD/i386
|
|
release is on CD1. If your BIOS does not support booting from CD, you will need
|
|
to create a boot floppy to install from. To create a boot floppy write
|
|
<i>CD1:5.6/i386/floppy56.fs</i> to a floppy and boot via the floppy drive.
|
|
|
|
<p>
|
|
Use <i>CD1:5.6/i386/floppyB56.fs</i> instead for greater SCSI controller
|
|
support, or <i>CD1:5.6/i386/floppyC56.fs</i> for better laptop support.
|
|
|
|
<p>
|
|
If your machine can boot from USB, you can write <i>install56.fs</i> or
|
|
<i>miniroot56.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.
|
|
|
|
<p>
|
|
To make a boot floppy under MS-DOS, use the "rawrite" utility located
|
|
at <i>CD1:5.6/tools/rawrite.exe</i>. To make the boot floppy under a Unix OS,
|
|
use the
|
|
<a href="https://man.openbsd.org/dd.1">dd(1)</a>
|
|
utility. The following is an example usage of
|
|
<a href="https://man.openbsd.org/dd.1">dd(1)</a>,
|
|
where the device could be "floppy", "rfd0c", or
|
|
"rfd0a".
|
|
|
|
<blockquote><pre>
|
|
# <kbd>dd if=<file> of=/dev/<device> bs=32k</kbd>
|
|
</pre></blockquote>
|
|
|
|
<p>
|
|
Make sure you use properly formatted perfect floppies with NO BAD BLOCKS or
|
|
your install will most likely fail. For more information on creating a boot
|
|
floppy and installing OpenBSD/i386 please refer to
|
|
<a href="faq/faq4.html#MkFlop">this page</a>.
|
|
|
|
<h3>OpenBSD/amd64:</h3>
|
|
|
|
<p>
|
|
The 5.6 release of OpenBSD/amd64 is located on CD2.
|
|
Boot from the CD to begin the install - you may need to adjust
|
|
your BIOS options first.
|
|
If you can't boot from the CD, you can create a boot floppy to install from.
|
|
To do this, write <i>CD2:5.6/amd64/floppy56.fs</i> to a floppy, then
|
|
boot from the floppy drive.
|
|
|
|
<p>
|
|
If your machine can boot from USB, you can write <i>install56.fs</i> or
|
|
<i>miniroot56.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>

<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>CD3:5.6/sparc64/floppy56.fs</i> or <i>CD3:5.6/sparc64/floppyB56.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>CD3:5.6/sparc64/miniroot56.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>5.6/alpha/floppy56.fs</i> or
|
|
<i>5.6/alpha/floppyB56.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

|
<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>
|
|

Copy 'boot' and 'bsd.rd' to a Mach or UniOS partition, and boot the bootloader
|
|
from the PROM, and the 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 cd56.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.

ok <kbd>boot cdrom 5.6/sparc/bsd.rd</kbd>
|
|
or
|
|
> <kbd>b sd(0,6,0)5.6/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>floppy56.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>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.

<h3>How to upgrade</h3>
|
|
<p>
|
|
If you already have an OpenBSD 5.5 system, and do not want to reinstall,
|
|
upgrade instructions and advice can be found in the
|
|
<a href="faq/upgrade56.html">Upgrade Guide</a>.

<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>
|
|
The <i>ports/</i> subdirectory is a checkout of the OpenBSD ports tree. 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 current with it, 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 anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_5_6</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
|
|
packages for the 5.6 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">ports@openbsd.org</a> is a good place to know.
