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

<p>This document contains the release notes for FreeBSD 5.4-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 5.4-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">``Obtaining FreeBSD'' 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 ``late-breaking'' 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 5.4-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
5.3-RELEASE. In general, changes described here are unique to the 5-STABLE branch unless
specifically marked as [MERGED] features.</p>

<p>Typical release note items document recent security advisories issued after
5.3-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>

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

<p>A bug in the <a

<span class="CITEREFENTRY"><span class="REFENTRYTITLE">fetch</span>(1)</span></a>
utility, which allows a malicious HTTP server to cause arbitrary portions of the client's

target="_top">FreeBSD-SA-05:04.ifconf</a>.</p>

<p>Several programming errors in <a

<span class="CITEREFENTRY"><span class="REFENTRYTITLE">cvs</span>(1)</span></a>, which
could potentially cause arbitrary code to be executed on CVS servers, have been
corrected. Further information can be found in security advisory <a

<h4 class="SECT3"><a id="NET-PROTO" name="NET-PROTO">2.2.3 Network Protocols</a></h4>

<p>The MTU feedback in IPv6 has been disabled when the sender writes data that must be
fragmented.</p>

<p>The Common Address Redundancy Protocol (CARP) has been implemented. CARP comes from
OpenBSD and allows multiple hosts to share an IP address, providing high availability and
load balancing. For more information, see the <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=carp&sektion=4&manpath=FreeBSD+5.4-RELEASE">

<p>The <a

<span class="CITEREFENTRY"><span class="REFENTRYTITLE">ipfw</span>(8)</span></a> <tt
class="LITERAL">ipfw fwd</tt> rule now supports the full packet destination manipulation
when the kernel option <tt class="LITERAL">options IPFIREWALL_FORWARD_EXTENDED</tt> is
specified in addition to <tt class="LITERAL">options IPFIREWALL_FORWARD</tt>. This kernel
option disables all restrictions to ensure proper behavior for locally generated packets
and allows redirection of packets destined to locally configured IP addresses. Note that
<a

<span class="CITEREFENTRY"><span class="REFENTRYTITLE">ipfw</span>(8)</span></a> rules

break.</p>

<span class="CITEREFENTRY"><span class="REFENTRYTITLE">ipnat</span>(8)</span></a> now
allows redirect rules to work for non-TCP/UDP packets.</p>

<p>Ongoing work is reducing the use of the Giant lock by the network protocol stack and
improving the locking strategies.</p>

<span class="CITEREFENTRY"><span class="REFENTRYTITLE">sppp</span>(4)</span></a> driver
now includes Frame Relay support.</p>

<p>A bug in TCP that sometimes caused RST packets to be ignored if the receive window was
zero bytes has been fixed.</p>

<p>Several bugs in the TCP SACK implementation have been fixed.</p>

<p>The KAME IPv4 IPsec implementation integrated in FreeBSD now supports TCP-MD5.</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

<span class="CITEREFENTRY"><span class="REFENTRYTITLE">matcd</span>(4)</span></a> driver
has been removed.</p>

<p>The SHSEC GEOM class has been added. It provides for the sharing of a secret between
multiple GEOM providers. All of these providers must be present in order to reveal the
secret. This feature is controlled by the <a

<span class="CITEREFENTRY"><span class="REFENTRYTITLE">gshsec</span>(8)</span></a>

<p>Information about newly-mounted cd9660 file systems (such as the presence of RockRidge
extensions) is now only printed if the kernel was booted in verbose mode. This change was
made to reduce the amount of (generally unnecessary) kernel log messages.</p>

<span class="CITEREFENTRY"><span class="REFENTRYTITLE">fsck</span>(8)</span></a>. This
change improves the startup speed when mounting large file systems after a crash. The
prior behavior can be restored by setting the <code

value.</p>

<p>A kernel panic in the NFS server has been fixed. More details can be found in errata

function now queries <tt class="LITERAL">A</tt> DNS resource records before <tt

Some broken DNS servers return <tt class="LITERAL">NXDOMAIN</tt> against non-existent <tt
class="LITERAL">AAAA</tt> queries, even when it should return <tt
class="LITERAL">NOERROR</tt> with empty return records. This is a problem for an
IPv4/IPv6 dual stack node because the <tt class="LITERAL">NXDOMAIN</tt> returned by the
first query of an <tt class="LITERAL">AAAA</tt> record makes the querying server stop
attempting to resolve the <tt class="LITERAL">A</tt> record if any. Also, this behavior
has been recognized as a potential denial-of-service attack (see <a
href="http://www.kb.cert.org/vuls/id/714121"
target="_top">http://www.kb.cert.org/vuls/id/714121</a> for more details). Note that

<p>In prior FreeBSD releases, the <tt class="FILENAME">disc1</tt> CD-ROM (or ISO image)
was a bootable installation disk containing the base system, ports tree, and common
packages. The <tt class="FILENAME">disc2</tt> CD-ROM (or ISO image) was a bootable ``fix

has now changed. For all architectures except ia64, the <tt class="FILENAME">disc1</tt>
image now contains the base system distribution files, ports tree, and the live
filesystem, making it suitable for both an initial installation and repair purposes. (On
the ia64, the live filesystem is on a separate disk due to its size.) Packages appear on
separate disks; in particular, the <tt class="FILENAME">disc2</tt> image contains
commonly packages such as desktop environments. Documents from the FreeBSD Documentation
