interface.
<li>...
</ul>
<p>
<li>Installer improvements:
<ul>
<li>...
</ul>
<p>
<li>Routing daemons and other userland network improvements:
<ul>
<li>Add routing table support to
<a href="http://man.openbsd.org/rc.d.8">rc.d(8)</a> and
<a href="http://man.openbsd.org/rcctl.8">rcctl(8)</a>.
<li>Let <a href="http://man.openbsd.org/nc.1">nc(1)</a>
support service names in addition to port numbers.
<li>Add <tt>-M</tt> and <tt>-m</tt> TTL flags to
<a href="http://man.openbsd.org/nc.1">nc(1)</a>.
<li>Add <tt>AF_UNIX</tt> support to
<a href="http://man.openbsd.org/tcpbench.1">tcpbench(1)</a>.
<li>Fixed a regression in
<a href="http://man.openbsd.org/rarpd.8">rarpd(8)</a>.
The daemon could hang if it was idle for a long time.
<li>Added the <tt>llprio</tt> option in
<a href="http://man.openbsd.org/ifconfig.8">ifconfig(8)</a>.
<li>...
</ul>
<p>
<li>Security improvements:
<ul>
<li><tt>W^X</tt> is now strictly enforced by default;
a program can only violate it if the executable is marked with
<tt>PT_OPENBSD_WXNEEDED</tt> and it is located on a filesystem
mounted with the <tt>wxallowed</tt>
<a href="http://man.openbsd.org/mount.8">mount(8)</a> option.
<li>The <a href="http://man.openbsd.org/setjmp.3">setjmp(3)</a>
family of functions now apply XOR cookies to stack and return-address
values in the jmpbuf on amd64, hppa, i386, mips64, and powerpc.
<li>SROP mitigation: <a href="http://man.openbsd.org/sigreturn.2">sigreturn(2)</a>
can now only be used by the kernel-provided signal trampoline,
with a cookie to detect attempts to reuse it.
<li>To deter code reuse exploits, <a href="http://man.openbsd.org/rc.8">rc(8)</a>
re-links libc.so on startup, placing the objects in a random order.
<li>In the <a href="http://man.openbsd.org/getpwnam.3">getpwnam(3)</a>
family of functions, stop opening the shadow database by default.
<li>Allow <a href="http://man.openbsd.org/tcpdump.8">tcpdump(8)</a>
<tt>-r</tt> to be started without root privileges.
<li>Remove
<a href="http://man.openbsd.org/OpenBSD-5.9/systrace">systrace</a>.
<li>Remove Linux emulation support.
<li>Remove support for the usermount option.
<li>The TCP SYN cache reseeds its random hash function from
time to time.
This prevents an attacker from calculating the distribution
of the hash function with a timing attack.
<li>To work against SYN flooding attacks the administrator can
change the size of the hash array now.
<a href="http://man.openbsd.org/netstat.1">netstat(1)</a>
<tt>-s -p tcp</tt> shows the relevant information to tune
the SYN cache with
<a href="http://man.openbsd.org/sysctl.8">sysctl(8)</a>
<tt>net.inet.tcp</tt>.
<li>The administrator can require root privileges for binding to some TCP
and UDP ports with
<a href="http://man.openbsd.org/sysctl.8">sysctl(8)</a>
<tt>net.inet.tcp.rootonly</tt> and
<a href="http://man.openbsd.org/sysctl.8">sysctl(8)</a>
<tt>net.inet.udp.rootonly</tt>.
<li>...
</ul>
<p>
<li>Assorted improvements:
<ul>
<li>The thread library can now be loaded into a single-threaded process.
<li>Improved symbol handling and standards compliance in libc.
For example, defining an <tt>open()</tt> function will no longer
interfere with the operation of
<a href="http://man.openbsd.org/fopen.3">fopen(3)</a>.
<li><tt>PT_TLS</tt> sections are now supported in initially loaded object.
<li>Improved handling of "no paths" and "empty path" in
<a href="http://man.openbsd.org/fts.3">fts(3)</a>.
<li>In <a href="http://man.openbsd.org/pcap.3">pcap(3)</a>,
provide the functions <tt>pcap_free_datalinks()</tt>
and <tt>pcap_offline_filter()</tt>.
<li>Many bugfixes and structural cleanup in the
<a href="http://man.openbsd.org/editline">editline(3)</a> library.
<li>Remove ancient
<a href="http://man.openbsd.org/OpenBSD-5.9/dbm.3">dbm(3)</a>
functions;
<a href="http://man.openbsd.org/ndbm.3">ndbm(3)</a> remains.
<li>Add <tt>setenv</tt> keyword for more powerful environment handling in
<a href="http://man.openbsd.org/doas.conf.5">doas.conf(5)</a>.
<li>Add <tt>-g</tt> and <tt>-p</tt> options to
<a href="http://man.openbsd.org/aucat.1">aucat.1</a>
for time positioning.
<li>Rewrite <a href="http://man.openbsd.org/audioctl.1">audioctl(1)</a>
with a simpler user interface.
<li>Add <tt>-F</tt> option to
<a href="http://man.openbsd.org/install.1">install(1)</a>
to <a href="http://man.openbsd.org/fsync.2">fsync(2)</a>
the file before closing it.
<li><a href="http://man.openbsd.org/kdump.1">kdump(1)</a>
now dumps <tt>pollfd</tt> structures.
<li>Improve various details of
<a href="http://man.openbsd.org/ksh.1">ksh(1)</a> POSIX compliance.
<li><a href="http://man.openbsd.org/mknod.8">mknod(8)</a> rewritten in a
<a href="http://man.openbsd.org/pledge.2">pledge(2)</a>-friendly
style and to support creating multiple devices at once.
<li>Implement <a href="http://man.openbsd.org/rcctl.8">rcctl(8)</a>
<tt>get all</tt> and <tt>getdef all</tt>.
<li>Implement the <a href="http://man.openbsd.org/rcs.1">rcs(1)</a>
<tt>-I</tt> (interactive) flag.
<li>In <a href="http://man.openbsd.org/rcs.1">rcs(1)</a>,
implement Mdocdate keyword substitution.
<li>In <a href="http://man.openbsd.org/top.1">top(1)</a>,
allow to filter process arguments if they are being displayed.
<li>Added UTF-8 support to
<a href="http://man.openbsd.org/fold.1">fold(1)</a> and
<a href="http://man.openbsd.org/rev.1">rev(1)</a>.
<li>Enable UTF-8 by default in
<a href="http://man.openbsd.org/xterm.1">xterm(1)</a> and
<a href="http://man.openbsd.org/pod2man.1">pod2man(1)</a>.
<li>Filter out non-ASCII characters in
<a href="http://man.openbsd.org/wall.1">wall(1)</a>.
<li>Handle the <a href="http://man.openbsd.org/?apropos=1&query=Ev%3DCOLUMNS">COLUMNS</a>
environment variable consistently across many programs.
<li>The options <tt>-c</tt> and <tt>-k</tt> allow to provide
TLS client certificates for
<a href="http://man.openbsd.org/syslogd.8">syslogd(8)</a>
on the sending side.
With that the receiving side can verify log messages
are authentic.
Note that syslogd does not have this check feature yet.
<li>When the klog buffer overflows, syslogd will write a log
message to show that some entries is missing.
<li>On OpenBSD/octeon, CPU cache write buffering is enabled
to improve performance.
<li><a href="http://man.openbsd.org/pkg_add.1">pkg_add(1)</a> and
<a href="http://man.openbsd.org/pkg_info.1">pkg_info(1)</a> now
understand a notion of branch to ease selection of some popular
packages such as python or php, e.g., say
<tt>pkg_add python%3.4</tt> to select the <tt>3.4</tt> branch,
and use <tt>pkg_info -zm</tt> to get a fuzzy listing with branch
selection suitable for <tt>pkg_add -l</tt>.
</ul>
<p>
<li>OpenSMTPD 5.9.1
<ul>
<li>...
</ul>
<p>
<li>OpenSSH 7.3

<li>...
</ul>
<li>The following significant bugs have been fixed in this release:
<ul>
<li>In <a href="http://man.openbsd.org/scp.1">scp(1)</a>
and <a href="http://man.openbsd.org/sftp.1">sftp(1)</a>,
prevent screwing up terminal settings by escaping bytes
not forming ASCII or UTF-8 characters.
<li>...
</ul>
</ul>
<p>
<li>OpenNTPD 6.0
<ul>
<li>When a single "constraint" is specified, try all returned addresses
until one succeeds, rather than the first returned address.
<li>Relaxed the constraint error margin to be proportional to the number
of NTP peers, avoid constant reconnections when there is a bad NTP
peer.
<li>Removed disabled
<a href="http://man.openbsd.org/hotplug.4">hotplug(4)</a>
sensor support.
<li>Added support for detecting crashes in constraint subprocesses.
<li>Moved the execution of constraints from the ntp process to the
parent process, allowing for better privilege separation since the
ntp process can be further restricted.
<li>Added
<a href="http://man.openbsd.org/pledge.2">pledge(2)</a>
support.
<li>Fixed high CPU usage when the network is down.
<li>Fixed various memory leaks.
<li>Switched to RMS for jitter calculations.
<li>Unified logging functions with other OpenBSD base programs.
<li>Set <tt>MOD_MAXERROR</tt> to avoid unsynced time status when using
ntp_adjtime.
<li>Fixed HTTP Timestamp header parsing to use
<a href="http://man.openbsd.org/strptime.3">strptime(3)</a>
in a more portable fashion.
<li>Hardened TLS for
<a href="http://man.openbsd.org/ntpd.8">ntpd(8)</a>
constraints, enabling server name verification.
</ul>
<p>
<li>LibreSSL 2.4.2
<ul>
<li>User-visible features:
<ul>
<li>Fixed some broken manpage links in the install target.
<li><tt>cert.pem</tt> has been reorganized and synced with Mozilla's
certificate store.
<li>Reliability fix, correcting an error when parsing certain ASN.1
elements over 16k in size.
<li>Implemented the IETF <i>ChaCha20-Poly1305</i> cipher suites.
<li>Fixed password prompts from
<a href="http://man.openbsd.org/openssl.1">openssl(1)</a>
to properly handle ^C.
</ul>
<li>Code improvements:
<ul>
<li>Fixed an <i>nginx</i> compatibility issue by adding an
'<tt>install_sw</tt>' build target.
<li>Changed default
<a href="http://man.openbsd.org/EVP_AEAD_CTX_init.3">EVP_aead_chacha20_poly1305(3)</a>
implementation to the IETF version, which is now the default.
<li>Reworked error handling in <tt>libtls</tt> so that configuration
errors are more visible.
<li>Added missing error handling around
<a href="http://man.openbsd.org/bn_wexpand.3">bn_wexpand(3)</a>
calls.
<li>Added
<a href="http://man.openbsd.org/explicit_bzero.3">explicit_bzero(3)</a>
calls for freed ASN.1 objects.
<li>Fixed <tt>X509_*set_object</tt> functions to return 0 on allocation
failure.
<li>Deprecated internal use of
<a href="http://man.openbsd.org/EVP_EncryptInit">EVP_[Cipher|Encrypt|Decrypt]_Final</a>.
<li>Fixed a problem that prevents the DSA signing algorithm from running
in constant time even if the flag <tt>BN_FLG_CONSTTIME</tt> is set.
<li>Fixed several issues in the OCSP code that could result in the
incorrect generation and parsing of OCSP requests. This remediates
a lack of error checking on time parsing in these functions, and
ensures that only <tt>GENERALIZEDTIME</tt> formats are accepted for
OCSP, as per <i>RFC 6960</i>.
</ul>
<li>The following CVEs have been fixed:
<ul>
<li><tt>CVE-2016-2105</tt>—EVP_EncodeUpdate overflow.
<li><tt>CVE-2016-2106</tt>—EVP_EncryptUpdate overflow.
<li><tt>CVE-2016-2107</tt>—padding oracle in AES-NI CBC MAC check.
<li><tt>CVE-2016-2108</tt>—memory corruption in the ASN.1 encoder.
<li><tt>CVE-2016-2109</tt>—ASN.1 BIO excessive memory allocation.

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.

<h3 id="upgrade"><font color="#0000e0">How to upgrade</font></h3>
If you already have an OpenBSD 5.9 system, and do not want to reinstall,
upgrade instructions and advice can be found in the
<a href="faq/upgrade60.html">Upgrade Guide</a>.
<p>
<hr>
<h3 id="sourcecode"><font color="#0000e0">Notes about the source code</font></h3>
<tt>src.tar.gz</tt> contains a source archive starting at <tt>/usr/src</tt>.
This file contains everything you need except for the kernel sources,
which are in a separate archive.
To extract:
<blockquote><pre>
# <b>mkdir -p /usr/src</b>
# <b>cd /usr/src</b>
# <b>tar xvfz /tmp/src.tar.gz</b>
</pre></blockquote>
<tt>sys.tar.gz</tt> contains a source archive starting at <tt>/usr/src/sys</tt>.
This file contains all the kernel sources you need to rebuild kernels.
To extract:
<blockquote><pre>
# <b>mkdir -p /usr/src/sys</b>
# <b>cd /usr/src</b>
# <b>tar xvfz /tmp/sys.tar.gz</b>
</pre></blockquote>
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.
<p>
<hr>
<h3 id="ports"><font color="#0000e0">Ports Tree</font></h3>
A ports tree archive is also provided. To extract:
<blockquote><pre>
# <b>cd /usr</b>
# <b>tar xvfz /tmp/ports.tar.gz</b>
</pre></blockquote>
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 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 <i>-stable</i> 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>
# <b>cd /usr/ports</b>
# <b>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_6_0</b>
</pre></blockquote>
[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 6.0 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.
