<h1 class="SECT1"><a id="NEW" name="NEW">2 What's
New</a></h1>
<p>This section describes many of the user-visible new or
changed features in FreeBSD since 4.0-RELEASE. It includes
items that are unique to the 5-CURRENT branch, as well as
some features that may have been recently merged to other
branches (after FreeBSD 4.6-RELEASE). The later items are
marked as [MERGED].</p>
<p>Typical release note items document new drivers or
hardware support, new commands or options, major bugfixes,
or contributed software upgrades. Applicable security
advisories issued after 4.6-RELEASE are also listed.</p>
<p>Many additional changes were made to FreeBSD that are
not listed here for lack of space. For example,
documentation was corrected and improved, minor bugs were
fixed, insecure coding practices were audited and
corrected, and source code was cleaned up.</p>

<span class="CITEREFENTRY"><span
class="REFENTRYTITLE">crypto</span>(9)</span></a>) has
been imported from OpenBSD. It provides a consistent
interface to hardware and software implementations of
cryptographic algorithms for use by the kernel and access
to cryptographic hardware for user-mode applications.
Hardware device drivers are provided to support
hifn-based cards (<a

<p>A <tt class="FILENAME">devctl</tt> device has been
added to allow userland programs to learn when devices
come and go in the device tree. This facility is
primarily used by the <a

<span class="CITEREFENTRY"><span
class="REFENTRYTITLE">devfs</span>(5)</span></a>, which
allows entries in the <tt class="FILENAME">/dev</tt>

<span class="CITEREFENTRY"><span
class="REFENTRYTITLE">devfs</span>(5)</span></a> is now
enabled by default and can be disabled by the <tt
class="LITERAL">NODEVFS</tt> kernel option. A ``rule''
subsystem permits the administrator to define certain
properties of new device nodes before they become visible
to the userland. Both static (e.g. <tt
class="FILENAME">/dev/speaker</tt>) and dynamic (e.g. <tt
class="FILENAME">/dev/bpf*</tt>, some removable devices)
nodes are supported. Each <a

<p>A new digi driver has been added to support PCI
Xr-based and ISA Xem Digiboard cards. A new <a

<span class="CITEREFENTRY"><span
class="REFENTRYTITLE">digictl</span>(8)</span></a>
program is (mainly) used to re-initialize cards that have
external port modules attached such as the PC/Xem. This
driver replaces the older dgm driver.</p>
<p>An <a

<span class="CITEREFENTRY"><span
class="REFENTRYTITLE">eaccess</span>(2)</span></a> system

<span class="CITEREFENTRY"><span
class="REFENTRYTITLE">access</span>(2)</span></a> except
that the former uses effective credentials rather than
real credentials.</p>
<p>Initial support has been added for FireWire devices
(see <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=firewire&sektion=4&manpath=FreeBSD+5.0-RELEASE">
<span class="CITEREFENTRY"><span

class="VARNAME">security.*</tt>.</p>
<p>The kernel environment is now dynamic, and can be
changed via the new <a

<p>The labpc(4) driver has been removed due to
``bitrot''.</p>
<p>The loader and kernel linker now look for files named
<tt class="FILENAME">linker.hints</tt> in each directory
with KLDs for a module name and version to KLD filename
mapping. The new <a

<span class="CITEREFENTRY"><span
class="REFENTRYTITLE">kldxref</span>(8)</span></a>
utility is used to generate these files.</p>
<p><a

<span class="CITEREFENTRY"><span
class="REFENTRYTITLE">lomac</span>(4)</span></a>, a
Low-Watermark Mandatory Access Control security facility,
has been added as a kernel module. It provides a drop-in
security mechanism in addition to the traditional
UID-based security facilities, requiring no additional
configuration from the administrator. Work on this
feature was sponsored by DARPA and NAI Labs.</p>
<p>FreeBSD now supports an extensible Mandatory Access
Control framework, the TrustedBSD MAC Framework. It
permits loadable kernel modules to link to the kernel at
compile-time, boot-time, or run-time to augment the
system security policy. The framework permits modules to
express interest in a variety of events, and also
provides common security policy services such as label
storage. A variety of sample policy modules are shipped
in this release, including implementations of fixed and
floating label Biba integrity models, Multi-Level
Security (MLS) with compartments, and a number of
augmented UNIX security models including a file system
firewall. This feature will permit easier development and
maintenance of local and vendor security extensions. The
extensibility service is enabled by adding <tt
class="LITERAL">options MAC</tt> to the kernel
configuration.</p>
<div class="NOTE">
<blockquote class="NOTE">
<p><b>Note:</b> The MAC framework is considered an
experimental feature in this release, and is not
enabled by default</p>

<span class="CITEREFENTRY"><span
class="REFENTRYTITLE">mutex</span>(9)</span></a>
profiling code has been added, enabled by the <tt
class="LITERAL">MUTEX_PROFILING</tt> kernel configuration
option. It enables the <tt
class="VARNAME">debug.mutex.prof.*</tt> hierarchy of
sysctl variables.</p>
<p>The <tt class="LITERAL">P1003_1B</tt> kernel option is
no longer used and has been removed.</p>
<p>PECOFF (Win32 Execution file format) support has been
added.</p>

<span class="CITEREFENTRY"><span
class="REFENTRYTITLE">random</span>(4)</span></a> device
has been rewritten to use the <b
class="APPLICATION">Yarrow</b> algorithm. It harvests
entropy from a variety of interrupt sources, including
the console devices, Ethernet and point-to-point network
interfaces, and mass-storage devices. Entropy from the <a

<span class="CITEREFENTRY"><span
class="REFENTRYTITLE">random</span>(4)</span></a> device
is now periodically saved to files in <tt
class="FILENAME">/var/db/entropy</tt>, as well as at
shutdown time. The semantics of <tt
class="FILENAME">/dev/random</tt> have changed; it never
blocks waiting for entropy bits but generates a stream of
pseudo-random data and now behaves exactly as <tt
class="FILENAME">/dev/urandom</tt>.</p>
<p>A new kernel option, <tt class="LITERAL">options
REGRESSION</tt>, enables interfaces and functionality
intended for use during correctness and regression
testing.</p>
<p><tt class="LITERAL">RLIMIT_VMEM</tt> support has been
added. This feature defines a new resource limit that
covers a process's entire virtual memory space, including
<a

<p>The uaudio driver, for USB audio devices, has been
added. [MERGED]</p>
<p>The ubsa driver has been added to support the Belkin
F5U103 (and compatible) USB-to-serial adaptors.</p>
<p>The <a

provide specific support for FTDI serial adapters, the
Prolific PL-2303 serial adapter and the SUNTAC Slipper U
VS-10U, respectively. [MERGED]</p>
<p>To increase security, the <tt
class="LITERAL">UCONSOLE</tt> kernel configuration option
has been removed.</p>
<p>The UserConfig boot-time kernel configuration feature,
usually used to enable, disable, or configure ISA
devices, has been removed. Its functionality has been
replaced by the kernel hints file in <tt

for connecting Handspring Visors via USB has been added.
[MERGED]</p>
<p>A VESA S3 linear framebuffer driver has been
added.</p>
<p>The kernel crashdump infrastructure has been revised,
to support new platforms and in general clean up the
logic in the code. One implication of this change is that
the on-disk format for kernel dumps has changed, and is
now byte-order-agnostic.</p>
<p>Extremely large swap areas (&gt;67 GB) no longer panic
the system.</p>
<p>Linker sets are now self-contained; gensetdefs(8) is
unnecessary and has been removed.</p>
<p>It is now possible to hardwire kernel environment
variables (such as tunables) at compile-time using <a

<p>Idle zeroing of pages can be enabled with the <tt
class="VARNAME">vm.idlezero_enable</tt> sysctl
variable.</p>
<p>The FreeBSD kernel scheduler now supports
Kernel-Scheduled Entities (KSEs), which provides support
for multiple threads of execution per process similar to
Scheduler Activations. At this point, the kernel has most
of the changes needed to support threading. The kernel
scheduler can schedule multiple threads per process, but
only on a single CPU at a time. More information can be
found in <a

<span class="CITEREFENTRY"><span
class="REFENTRYTITLE">conscontrol</span>(8)</span></a>
utility helps to manage the different consoles.</p>
<p>The kernel memory allocator is now a slab memory
allocator, similar to that used in Solaris. This is a
SMP-safe memory allocator that has near-linear
performance as the number of CPUs increases. It also
allows for reduced memory fragmentation.</p>
<div class="SECT3">
<hr />
<h3 class="SECT3"><a id="AEN401" name="AEN401">2.1.1
Processor/Motherboard Support</a></h3>
<p>SMP support has been largely reworked, incorporating
code from BSD/OS 5.0. One of the main features of SMPng
(``SMP Next Generation'') is to allow more processes to
run in kernel, without the need for spin locks that can
dramatically reduce the efficiency of multiple
processors. Interrupt handlers now have contexts
associated with them that allow them to be blocked,
which reduces the need to lock out interrupts.</p>
<p>Support for the 80386 processor has been removed
from the <tt class="FILENAME">GENERIC</tt> kernel, as
this code seriously pessimizes performance on other
IA32 processors. The <tt class="LITERAL">I386_CPU</tt>
kernel option to support the 80386 processor is now
mutually exclusive with support for other IA32
processors; this should slightly improve performance on
the 80386 due to the elimination of runtime processor
type checks. Custom kernels that will run on the 80386
can still be built by changing the CPU options in the
kernel configuration file to only include <tt
class="LITERAL">I386_CPU</tt>.</p>
<p>The <tt class="LITERAL">CPU_DISABLE_CMPXCHG</tt>
kernel configuration option has been added. Enabling
this option has been shown to dramatically improve
performance on VMWare client OS installs.</p>

<p>Network devices now automatically appear as special

hardware ioctls (not protocol or routing) can be
performed on these devices. The <tt

on the special <tt class="FILENAME">/dev/network</tt>

<p>``Zero copy'' support has been added to the
networking stack. This feature can eliminate a copy of
network data between the kernel and userland, which is
one of the more significant bottlenecks in network
throughput. The send-side code should work with almost
any network adapter, while the receive-side code
requires a network adapter with an MTU of at least one
memory page size (for example, jumbo frames on Gigabit
Ethernet). For more information, see <a

<p>The client-side and server-side of the NFS code in
the kernel used to be intertwined in various complex
ways. They have been split apart for ease of

<li>
<p>The inode has been expanded to 256 bytes to make
space for 64-bit block pointers.</p>
</li>
<li>
<p>A file-creation time field has been added.</p>
</li>
<li>
<p>A native extended attributes implementation has

Ports/Packages Collection Infrastructure</a></h3>
<p><b class="APPLICATION">BSDPAN</b>, a collection of
modules that provides tighter integration of <b
class="APPLICATION">Perl</b> into the FreeBSD Ports
Collection, has been added.</p>
<p>For some time, FreeBSD 5.0-CURRENT (as well as some
4.X releases) included a pkg_update(1) utility to
update installed packages, as well as their
dependencies. This utility has been removed; a superset
of its functionality can be found in the <a
href="http://www.FreeBSD.org/cgi/url.cgi?ports/sysutils/portupgrade/pkg-descr">
<tt class="FILENAME">sysutils/portupgrade</tt></a>
port.</p>
<p><a

<span class="CITEREFENTRY"><span
class="REFENTRYTITLE">pkg_version</span>(1)</span></a>,
formerly a Perl script, has been rewritten in C. The
<tt class="OPTION">-c</tt>, frequently misused, has
been removed. The <a
href="http://www.FreeBSD.org/cgi/url.cgi?ports/sysutils/portupgrade/pkg-descr">
<tt class="FILENAME">sysutils/portupgrade</tt></a> port
provides a supported and safer alternative.</p>
<p>The Ports Collection infrastructure now uses <b
class="APPLICATION">XFree86</b> 4.2.1 as the default
version of the X Window System for the purposes of
satisfying dependencies. To return to using <b
class="APPLICATION">XFree86</b> 3.3.6, add the
following line to <tt
class="FILENAME">/etc/make.conf</tt>: [MERGED]</p>
<pre class="PROGRAMLISTING">
XFREE86_VERSION=3

<p>The libraries installed by the <a
href="http://www.FreeBSD.org/cgi/url.cgi?ports/emulators/linux_base/pkg-descr">
<tt class="FILENAME">emulators/linux_base</tt></a> port
(required for Linux emulation) have been updated; they
now correspond to those included with <b
class="APPLICATION">Red Hat Linux</b> 7.1. [MERGED]</p>
<p>By default, packages generated by the Ports
Collection (as well as the packages on the FTP sites)
are now compressed using <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=bzip2&sektion=1&manpath=FreeBSD+5.0-RELEASE">
<span class="CITEREFENTRY"><span
class="REFENTRYTITLE">bzip2</span>(1)</span></a>,
rather than <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=gzip&sektion=1&manpath=FreeBSD+5.0-RELEASE">
<span class="CITEREFENTRY"><span
class="REFENTRYTITLE">gzip</span>(1)</span></a>. (Thus,
they now have a <tt class="FILENAME">.tbz</tt>
extension, rather than a <tt class="FILENAME">.tgz</tt>
extension.) The package tools have been updated to
handle the new format.</p>
<p>The Ports Collection now maintains a separate index
file (<tt class="FILENAME">/usr/ports/INDEX-5</tt>) for
use with FreeBSD 5-CURRENT. A major motivation for a
separate index file is to cope with dependencies (such
as <a
href="http://www.FreeBSD.org/cgi/url.cgi?ports/lang/perl5/pkg-descr">
<tt class="FILENAME">lang/perl5</tt></a>) that exist in
FreeBSD 5-CURRENT but not FreeBSD 4-STABLE. The index
file for each package set is still called <tt
class="FILENAME">INDEX</tt>.</p>

<p>The <tt class="FILENAME">bin</tt> distribution has
been renamed <tt class="FILENAME">base</tt>, in order to
make creation of combined install/recovery disks
easier.</p>
<p>It is now possible to make releases of FreeBSD
5-CURRENT on a FreeBSD 4-STABLE host and vice versa.
Cross-architecture (building a release for a target
architecture on a host of a different architecture)
releases are also possible. See <a

<p>A third <tt class="FILENAME">drivers.flp</tt> floppy

<tt class="FILENAME">mfsroot.flp</tt> image.</p>
