<h2 class="SECT1"><a id="INTRO" name="INTRO">1 Introduction</a></h2>

<p>This document contains the release notes for FreeBSD 6.4-RELEASE on the AMD64 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 6.4-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 6.4-RELEASE can be found on the FreeBSD Web site.</p>

<hr />
<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
6.3-RELEASE.</p>

<p>Typical release note items document recent security advisories issued after
6.3-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>

<div class="SECT2">

<h3 class="SECT2"><a id="SECURITY" name="SECURITY">2.1 Security Advisories</a></h3>

<p>Problems described in the following security advisories has been fixed. For more
information, consult the individual advisories available from <a

<p>The opencrypto framework (<a

<span class="CITEREFENTRY"><span class="REFENTRYTITLE">ipsec</span>(4)</span></a>
subsystem now support Camellia block cipher.</p>

<p>The FreeBSD kernel <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=malloc&sektion=9&manpath=FreeBSD+6.4-RELEASE">
<span class="CITEREFENTRY"><span class="REFENTRYTITLE">malloc</span>(9)</span></a> now
supports buffer corruption protection (RedZone). This detects both buffer underflow and
buffer overflow bugs at runtime on <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=free&sektion=9&manpath=FreeBSD+6.4-RELEASE">
<span class="CITEREFENTRY"><span class="REFENTRYTITLE">free</span>(9)</span></a> and <a

<span class="CITEREFENTRY"><span class="REFENTRYTITLE">realloc</span>(9)</span></a> and
prints backtraces from where memory was allocated and from where it was freed. For more
details, see <tt class="LITERAL">DEBUG_REDZONE</tt> kernel option.</p>

<p>The client side functionality of <a

<span class="CITEREFENTRY"><span class="REFENTRYTITLE">rpc.lockd</span>(8)</span></a> has
been implemented in FreeBSD kernel. This implementation provides the correct semantics
for <a

<span class="CITEREFENTRY"><span class="REFENTRYTITLE">flock</span>(2)</span></a> style
locks which are used by the <a

<span class="CITEREFENTRY"><span class="REFENTRYTITLE">lockf</span>(1)</span></a> command

<span class="CITEREFENTRY"><span class="REFENTRYTITLE">pidfile</span>(3)</span></a>
library. It also implements recovery from server restarts and ensures that dirty cache
blocks are written to the server before obtaining locks (allowing multiple clients to use
file locking to safely share data). Also, a new kernel option <tt class="LITERAL">options
NFSLOCKD</tt> has been added and enabled by default. If the kernel support is enabled, <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=rpc.lockd&sektion=8&manpath=FreeBSD+6.4-RELEASE">
<span class="CITEREFENTRY"><span class="REFENTRYTITLE">rpc.lockd</span>(8)</span></a>

subsystem now supports <tt class="LITERAL">fast</tt> mode operation which allows certain
packets to bypass the dummynet scheduler. This can achieve lower latency and lower
overhead when the packet flow is under the pipe bandwidth, and eliminate recursion in the
subsystem. The new sysctl variable <code

feature.</p>
