<h2 class="SECT1"><a id="INTRO" name="INTRO">1 Introduction</a></h2>
<p>This document contains the release notes for FreeBSD 6.0-RELEASE on the UltraSPARC
hardware platform. It describes recently added, changed, or deleted features of FreeBSD.
It also provides some notes on upgrading from previous versions of FreeBSD.</p>
<p>This distribution of FreeBSD 6.0-RELEASE is a release distribution. It can be found at
<a href="ftp://ftp.FreeBSD.org/" target="_top">ftp://ftp.FreeBSD.org/</a> or any of its
mirrors. More information on obtaining this (or other) release distributions of FreeBSD
can be found in the <a
href="http://www.FreeBSD.org/doc/en_US.ISO8859-1/books/handbook/mirrors.html"
target="_top">&#8220;Obtaining FreeBSD&#8221; appendix</a> to the <a
href="http://www.FreeBSD.org/doc/en_US.ISO8859-1/books/handbook/" target="_top">FreeBSD
Handbook</a>.</p>
<p>All users are encouraged to consult the release errata before installing FreeBSD. The
errata document is updated with &#8220;late-breaking&#8221; information discovered late
in the release cycle or after the release. Typically, it contains information on known
bugs, security advisories, and corrections to documentation. An up-to-date copy of the
errata for FreeBSD 6.0-RELEASE can be found on the FreeBSD Web site.</p>

<h2 class="SECT1"><a id="NEW" name="NEW">2 What's New</a></h2>
<p>This section describes the most user-visible new or changed features in FreeBSD since
5.4-RELEASE. In general, changes described here are unique to the 6-STABLE branch unless
specifically marked as [MERGED] features.</p>
<p>Typical release note items document recent security advisories issued after
5.4-RELEASE, new drivers or hardware support, new commands or options, major bug fixes,
or contributed software upgrades. They may also list changes to major ports/packages or
release engineering practices. Clearly the release notes cannot list every single change
made to FreeBSD between releases; this document focuses primarily on security advisories,
user-visible changes, and major architectural improvements.</p>

<p>A bug in the <a

<p>Two buffer overflows in the TELNET client program have been corrected. They could have

<p>An error in the default permissions on the <tt class="FILENAME">/dev/iir</tt> device

<span class="CITEREFENTRY"><span class="REFENTRYTITLE">iir</span>(4)</span></a> driver,

<p>A bug in the validation of <a

<span class="CITEREFENTRY"><span class="REFENTRYTITLE">i386_get_ldt</span>(2)</span></a>
system call input arguments, which may allow kernel memory to be disclosed to a user

<p>A bug in the <a

<span class="CITEREFENTRY"><span class="REFENTRYTITLE">tcpdump</span>(1)</span></a>
utility which allows a malicious remote user to cause a denial-of-service by using

<p>Two problems in the <a

<span class="CITEREFENTRY"><span class="REFENTRYTITLE">gzip</span>(1)</span></a> utility

<p>A bug in <b class="APPLICATION">BIND 9</b> DNSSEC has been fixed. When DNSSEC is

target="_top">FreeBSD-SA-05:14.bzip2</a>. [MERGED]</p>
<p>Two problems in FreeBSD's TCP stack have been fixed. They could allow attackers to

<h3 class="SECT2"><a id="KERNEL" name="KERNEL">2.2 Kernel Changes</a></h3>
<p>The kernel debugger <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=ddb&sektion=4&manpath=FreeBSD+6.0-RELEASE">
<span class="CITEREFENTRY"><span class="REFENTRYTITLE">ddb</span>(4)</span></a> now
supports a <tt class="COMMAND">show alllocks</tt> command, which dumps a list of
processes and threads currently holding sleep mutexes (and spin mutexes for the current
thread). [MERGED]</p>
<p>The <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=ichsmb&sektion=4&manpath=FreeBSD+6.0-RELEASE">
<span class="CITEREFENTRY"><span class="REFENTRYTITLE">ichsmb</span>(4)</span></a> driver
is now available as a loadable kernel module.</p>
<p>The <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=jail&sektion=8&manpath=FreeBSD+6.0-RELEASE">
<span class="CITEREFENTRY"><span class="REFENTRYTITLE">jail</span>(8)</span></a> feature
now supports a new sysctl <code class="VARNAME">security.jail.chflags_allowed</code>,
which controls the behavior of <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=chflags&sektion=1&manpath=FreeBSD+6.0-RELEASE">
<span class="CITEREFENTRY"><span class="REFENTRYTITLE">chflags</span>(1)</span></a>
within a jail. If set to <tt class="LITERAL">0</tt> (the default), then a jailed <tt
class="USERNAME">root</tt> user is treated as an unprivileged user; if set to <tt
class="LITERAL">1</tt>, then a jailed root user is treated the same as an unjailed <tt
class="USERNAME">root</tt> user. [MERGED]</p>
<p>A sysctl <code class="VARNAME">security.jail.getfsstatroot_only</code> has been
renamed to <code class="VARNAME">security.jail.enforce_statfs</code> and now supports the
following policies:</p>

<p>The loader tunable <code class="VARNAME">debug.mpsafevm</code> has been enabled by
default. [MERGED]</p>

<span class="CITEREFENTRY"><span class="REFENTRYTITLE">memguard</span>(9)</span></a>, a
kernel memory allocator designed to help detect &#8220;tamper-after-free&#8221;
scenarios, has been added. This must be explicitly enabled via <tt
class="LITERAL">options DEBUG_MEMGUARD</tt>, plus small kernel modifications. It is
generally intended for use by kernel developers.</p>
<p><code class="VARNAME">struct ifnet</code> and the network interface API have been
changed. Due to ABI incompatibility, all drivers not in the FreeBSD base system need to
be updated to use the new API and recompiled.</p>
<p>A number of bugs have been fixed in the ULE scheduler. [MERGED]</p>
<p>Fine-grained locking to allow much of the VFS stack to run without the Giant lock has
been added. This is enabled by default on the alpha, amd64, and i386 architectures, and
can be disabled by setting the loader tunable (and sysctl variable) <code
class="VARNAME">debug.mpsafevfs</code> to <tt class="LITERAL">0</tt>.</p>
<p>System V IPC objects (message queues, semaphores, and shared memory) now have support

amd64, and powerpc) or 8KB (sparc64 and ia64). As a result, compatibility modules need to
be rebuilt to stay synchronized with data structure changes in the kernel.</p>
<p>A new tunable <code class="VARNAME">vm.blacklist</code> has been added. This can hold
a space or comma separated list of physical addresses. The pages containing these
physical addresses will not be added to the free list and thus will effectively be
ignored by the FreeBSD VM system. The physical addresses of any ignored pages are listed
in the message buffer as well.</p>

<p>A bug in TCP that sometimes caused RST packets to be ignored if the receive window was
zero bytes has been fixed. [MERGED]</p>
<p>The <tt class="LITERAL">RST</tt> handling of the FreeBSD TCP stack has been improved
to make reset attacks as difficult as possible while maintaining compatibility with the
widest range of TCP stacks. The algorithm is as follows: For connections in the <tt
class="LITERAL">ESTABLISHED</tt> state, only resets with sequence numbers exactly
matching <code class="VARNAME">last_ack_sent</code> will cause a reset; all other
segments will be silently dropped. For connections in all other states, a reset anywhere
in the window will cause the connection to be reset. All other segments will be silently
dropped. Note that this behavior technically violates the RFC 793 specification; the
conventional (but less secure) behavior can be restored by setting a new sysctl <code
class="VARNAME">net.inet.tcp.insecure_rst</code> to <tt class="LITERAL">1</tt>.
[MERGED]</p>
<p>Several bugs in the TCP SACK implementation have been fixed. [MERGED]</p>
<p>RFC 1644 T/TCP support has been removed. This is because the design is based on a weak
security model that can easily permit denial-of-service attacks. This TCP extension has
been considered a defective one in a recent Internet Draft.</p>
<p>The KAME IPv4 IPsec implementation integrated in FreeBSD now supports TCP-MD5.
[MERGED]</p>
<p>Random ephemeral port number allocation has led to some problems with port reuse at
high connection rates. This feature is now disabled during periods of high connection
rates; whenever new connections are created faster than <code
class="VARNAME">net.inet.ip.portrange.randomcps</code> per second, port number
randomization is disabled for the next <code
class="VARNAME">net.inet.ip.portrange.randomtime</code> seconds. The default values for
these two sysctl variables are <tt class="LITERAL">10</tt> and <tt
class="LITERAL">45</tt>, respectively. [MERGED]</p>
<p>Fine-grained locking has been applied to many of the data structures in the IPX/SPX
protocol stack. While not fully MPSAFE at this point, it is generally safe to use IPX/SPX
without the Giant lock (in other words, the <code class="VARNAME">debug.mpsafenet</code>
sysctl variable may be set to <tt class="LITERAL">1</tt>).</p>
<p>Unix domain sockets now support the <tt class="LITERAL">LOCAL_CREDS</tt> and <tt
