<title>What's New</title>
|
|
|
|
<para>This section describes the most user-visible new or changed
|
|
features in &os; since &release.prev;. Typical release note items
|
|
document new drivers or hardware support, new commands or options,
|
|
major bugfixes, or contributed software upgrades. Security
|
|
advisories issued after &release.prev; are also listed. In
|
|
general, changes described here are unique to the &release.branch;
|
|
branch unless specifically marked as &merged; features.</para>
|
|
|
|
<para>Many additional changes were made to &os; 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.</para>

<title>Kernel Changes</title>
|
|
|
|
<para arch="i386">The &man.amdpm.4; driver has been added to
|
|
provide access to the system monitoring functions of the AMD 756
|
|
chipset. &merged;</para>
|
|
|
|
<para>The &man.agp.4; driver for AGP devices has been
|
|
added. &merged;</para>
|
|
|
|
<para>A new &man.ddb.4; command <command>show pcpu</command> lists
|
|
some of the per-CPU data.</para>
|
|
|
|
<para>Two new &man.ddb.4; commands, <command>hwatch</command> and
|
|
<command>dhwatch</command>, have been introduced. Analogous to
|
|
<command>watch</command> and <command>dwatch</command>, they
|
|
install hardware watchpoints (as opposed to software
|
|
watchpoints) if supported by the architecture. &merged;</para>
|
|
|
|
<para>&man.devfs.5;, which allows entries in the
|
|
<filename>/dev</filename> directory to be built automatically
|
|
and supports more flexible attachment of devices, has been
|
|
largely reworked. &man.devfs.5; is now enabled by default and
|
|
can be disabled by the <literal>NODEVFS</literal> kernel
|
|
option.</para>
|
|
|
|
<para>The dgm driver has been removed in favor of the digi driver.</para>
|
|
|
|
<para>A new digi driver has been added to support PCI Xr-based and
|
|
ISA Xem Digiboard cards. A new &man.digictl.8; program is
|
|
(mainly) used to re-initialize cards that have external port
|
|
modules attached such as the PC/Xem.</para>
|
|
|
|
<para>An &man.eaccess.2; system call has been added, similar to
|
|
&man.access.2; except that the former uses effective credentials
|
|
rather than real credentials.</para>
|
|
|
|
<para arch="sparc64">Support has been added for EBus-based
|
|
devices.</para>
|
|
|
|
<para arch="i386">The &man.ichsmb.4; driver for the Intel 82801AA
|
|
(ICH) SMBus controller and compatibles has been
|
|
added. &merged;</para>
|
|
|
|
<para>Each &man.jail.2; environment can now run under its own
|
|
securelevel.</para>
|
|
|
|
<para>The tunable sysctl variables for &man.jail.2; have moved
|
|
from <varname>jail.*</varname> to the
|
|
<varname>security.*</varname> hierarchy. Other security-related
|
|
sysctl variables have moved from <varname>kern.security.*</varname> to
|
|
<varname>security.*</varname>.</para>
|
|
|
|
<para>The <varname>kern.maxvnodes</varname> limit now properly
|
|
limits the number of vnodes in use. Previously only vnodes with
|
|
no cached pages could be freed; this could allow the number of
|
|
vnodes to grow without limit on large-memory machines accessing
|
|
many small files. A <literal>vnlru</literal> kernel thread
|
|
helps to flush and reuse vnodes. &merged;</para>
|
|
|
|
<para>The kernel message buffer is now accessible by the
|
|
(machine-independent) <varname>kern.msgbuf</varname> sysctl
|
|
variable; &man.dmesg.8; no longer needs to be SGID
|
|
<groupname>kmem</groupname>. &merged;</para>
|
|
|
|
<para>The &man.kqueue.2; event notification facility was added to
|
|
the &os; kernel. This is a new interface which is able to
|
|
replace &man.poll.2;/&man.select.2;, offering improved
|
|
performance, as well as the ability to report many different
|
|
types of events. Support for monitoring changes in sockets,
|
|
pipes, fifos, and files are present, as well as for signals and
|
|
processes. &merged;</para>
|
|
|
|
<para arch="i386">A new <varname>KVA_SPACE</varname> kernel option
|
|
can be used to reconfigure the size of the kernel virtual
|
|
address space. &merged;</para>
|
|
|
|
<para>The &man.labpc.4; driver has been removed due to
|
|
<quote>bitrot</quote>.</para>
|
|
|
|
<para>The loader and kernel linker now look for files named
|
|
<filename>linker.hints</filename> in each directory with KLDs
|
|
for a module name and version to KLD filename mapping. The new
|
|
&man.kldxref.8; utility is used to generate these files.</para>
|
|
|
|
<para>Linux emulation now supports the kernel functionality
|
|
required by the
|
|
<filename role="package">emulators/linux_base-7</filename>
|
|
(RedHat 7.X emulation) port. &merged;</para>
|
|
|
|
<para>Linux emulation now requires <literal>options
|
|
SYSVSEM</literal> in the kernel configuration. &merged;</para>
|
|
|
|
<para>&man.lomac.4;, 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.</para>
|
|
|
|
<para>The <varname>maxusers</varname> kernel configuration
|
|
parameter is now a boot-time tunable variable. The kernel
|
|
parameters derived from <varname>maxusers</varname> are now also
|
|
tunables and can be overridden at boot-time. The
|
|
<varname>hz</varname> parameter is also now a
|
|
tunable. &merged;</para>
|
|
|
|
<para>Specifying a value of <literal>0</literal> for the
|
|
<varname>maxusers</varname> kernel configuration parameter will
|
|
now cause an appropriate value to be calculated at boot-time
|
|
(between 32 and 384, depending on the amount of memory present).
|
|
This value is now the default for all
|
|
<filename>GENERIC</filename> kernels. &merged;</para>
|
|
|
|
<para arch="alpha">A <varname>MAXMEM</varname> kernel option,
|
|
along with the <varname>hw.physmem</varname> loader tunable, can
|
|
be used to artificially reduce the memory size of a machine for
|
|
testing (or other purposes). &merged;</para>
|
|
|
|
<para>The kernel configuration parameters
|
|
<varname>MAXTSIZ</varname>, <varname>DFLDSIZ</varname>,
|
|
<varname>MAXDSIZ</varname>, <varname>DFLSSIZ</varname>,
|
|
<varname>MAXSSIZ</varname>, and <varname>SGROWSIZ</varname> are
|
|
all loader tunables (<varname>kern.maxtsiz</varname>,
|
|
<varname>kern.maxdfldsiz</varname>, etc.). &merged;</para>
|
|
|
|
<para arch="i386">The <literal>NCPU</literal>, <literal>NAPIC</literal>,
|
|
<literal>NBUS</literal>, and <literal>NINTR</literal> kernel
|
|
configuration options, for configuring SMP kernels, have been
|
|
removed. <literal>NCPU</literal> is now set to a maximum of 16,
|
|
and the other, aforementioned options are now
|
|
dynamic. &merged;</para>
|
|
|
|
<para>A &man.nmdm.4; null-modem terminal driver has been added.
|
|
&merged;</para>
|
|
|
|
<para>The <literal>O_DIRECT</literal> flag has been added to
|
|
&man.open.2; and &man.fcntl.2;. Specifying this flag for open
|
|
files will attempt to minimize the cache effects of reading and
|
|
writing. &merged;</para>
|
|
|
|
<para>An &man.orm.4; device has been added to claim the option
|
|
ROMs in the ISA memory I/O space, to prevent other drivers from
|
|
mistakenly assigning addresses that conflict with these
|
|
ROMs. &merged;</para>
|
|
|
|
<para arch="i386">PECOFF (Win32 Execution file format) support has
|
|
been added.</para>
|
|
|
|
<para arch="i386">The pmc driver, which supports the power
|
|
management controller of the NEC PC-98NOTE, has been
|
|
added. &merged;</para>
|
|
|
|
<para>POSIX.1b Shared Memory Objects are now supported. The
|
|
implementation uses regular files, but automatically enables the
|
|
MAP_NOSYNC flag when they are &man.mmap.2;-ed. &merged;</para>
|
|
|
|
<para>Replaced the <literal>PQ_*CACHE</literal> options with a
|
|
single <literal>PQ_CACHESIZE</literal> option to be set to the
|
|
cache size in kilobytes. The old options are still supported
|
|
for backwards compatibility. &merged;</para>
|
|
|
|
<para arch="i386">The &man.puc.4; (PCI <quote>Universal</quote>
|
|
Communications) driver has been added, to help connect PCI-based
|
|
serial ports to the &man.sio.4; driver. &merged;</para>
|
|
|
|
<para>The &man.random.4; device has been rewritten to use the
|
|
<application>Yarrow</application> 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 &man.random.4;
|
|
device is now periodically saved to files in
|
|
<filename>/var/db/entropy</filename>, as well as at shutdown
|
|
time. The semantics of <filename>/dev/random</filename> have
|
|
changed; it never blocks waiting for entropy bits but generates
|
|
a stream of pseudo-random data and now behaves exactly as
|
|
<filename>/dev/urandom</filename>.</para>
|
|
|
|
<para>A new kernel option, <literal>options REGRESSION</literal>,
|
|
enables interfaces and functionality intended for use during
|
|
correctness and regression testing.</para>
|
|
|
|
<para arch="sparc64">Support has been added for SBus-based
|
|
devices.</para>
|
|
|
|
<para>The &man.snp.4; device is no longer static and can now be
|
|
compiled as a module. &merged;</para>
|
|
|
|
<para arch="i386">The &man.spic.4; driver, which provides access
|
|
to the jog dial device on some Sony laptops, has been
|
|
added.</para>
|
|
|
|
<para>The &man.syscons.4; driver now supports keyboard-controlled
|
|
pasting, by default bound to
|
|
<keycap>Shift</keycap>-<keycap>Insert</keycap>.</para>
|
|
|
|
<para>Support for USB devices was added to the
|
|
<filename>GENERIC</filename> kernel and to the installation
|
|
programs to support USB devices out of the box. Note that SRM
|
|
does not support USB devices at the moment, so you must still
|
|
use an AT keyboard if you are not using a serial
|
|
console. &merged;</para>
|
|
|
|
<para arch="i386">The umodem driver for USB modems has been added.
|
|
Support is provided for the 3Com 5605 and Metricom Ricochet GS
|
|
wireless USB modems. &merged;</para>
|
|
|
|
<para arch="i386">The &man.uscanner.4; driver for basic USB
|
|
scanner support using SANE has been added. See <ulink
|
|
url="http://www.mostang.com/sane/">the SANE home page</ulink>
|
|
for supported scanners. The HP ScanJet 4100C, 5200C and 6300C
|
|
are known to be working. &merged;</para>
|
|
|
|
<para>The <literal>USER_LDT</literal> kernel option is now
|
|
activated by default.</para>
|
|
|
|
<para>A VESA S3 linear framebuffer driver has been added.</para>
|
|
|
|
<!-- Above this line, sort kernel changes by manpage/keyword-->
|
|
|
|
<para>Write combining for crashdumps has been implemented. This
|
|
feature is useful when write caching is disabled on both SCSI
|
|
and IDE disks, where large memory dumps could take up to an hour
|
|
to complete. &merged;</para>
|
|
|
|
<para>Extremely large swap areas (>67 GB) no longer panic the
|
|
system.</para>
|
|
|
|
<para arch="alpha">Support for threads under Linux emulation has
|
|
been added.</para>
|
|
|
|
<para>The <maketarget>buildkernel</maketarget> target now gets the
|
|
name of the configuration(s) to build from the
|
|
<varname>KERNCONF</varname> variable, not
|
|
<varname>KERNEL</varname>. It is no longer required, in some
|
|
cases, for a <maketarget>buildworld</maketarget> to precede a
|
|
<maketarget>buildkernel</maketarget>. (The
|
|
<maketarget>buildworld</maketarget> is still required when
|
|
upgrading across major releases, across
|
|
<application>binutil</application> updates and when
|
|
&man.config.8; changes version.) &merged;</para>
|
|
|
|
<para>The out-of-swap process termination code now begins killing
|
|
processes earlier to avoid deadlocks; it now also takes into
|
|
account the swap space used by processes when computing the
|
|
process sizes. &merged;</para>
|
|
|
|
<para>Linker sets are now self-contained; &man.gensetdefs.8; is
|
|
unnecessary and has been removed.</para>
|
|
|
|
<para>Numerous SMP-friendly changes have been made to the kernel's
|
|
mbuf allocator.</para>
|
|
|
|
<para>Network device cloning has been implemented, and the
|
|
&man.gif.4; device has been modified to take advantage of it.
|
|
Thus, instead of specifying how many &man.gif.4; interfaces are
|
|
available in kernel configuration files, &man.ifconfig.8;'s
|
|
<option>create</option> option should be used when another device
|
|
instance is desired. &merged;</para>
|
|
|
|
<para>It is now possible to hardwire kernel environment variables
|
|
(such as tuneables) at compile-time using &man.config.8;'s
|
|
<literal>ENV</literal> directive.</para>
|
|
|
|
<para>Idle zeroing of pages can be enabled with the
|
|
<varname>vm.zeroidle_enable</varname> sysctl variable.</para>
|
|
|
|
<para arch="i386">The load addresses of kernels are now exported
|
|
to the symbol table and various hard-coded constants have been
|
|
removed so that utilities such as &man.ps.1; can work with
|
|
kernels compiled at different addresses. &merged;</para>
|
|
|
|
<para>Coredumps of large processes (or of a large number of
|
|
processes) no longer lock up the machine for long periods of
|
|
time. &merged;</para>
|
|
|
|
<para>The kernel is now aware of the concept that there are
|
|
smaller units of scheduling than a process (but only one thread
|
|
per process is allowed at this time).</para>
|
|
|
|
<para>The kernel now has support for multiple low-level console
|
|
devices. The new &man.conscontrol.8; utility helps to manage
|
|
the different consoles.</para>
|
|
|
|
<para arch="alpha">The console driver has gained support for
|
|
TGA-based display adapters.</para>
|
|
|
|
<para>The kernel on the installation CDs is now separated from the
|
|
<filename>mfsroot</filename> image. This permits the use of a
|
|
full kernel when installing from CD on machines that support CD
|
|
booting (instead of the stripped-down kernel used on
|
|
floppies). &merged;</para>
|
|
|
|
<para>The system load average computation now adds some jitter to
|
|
the timing of samples, in order to avoid synchronization with
|
|
processes that run periodically. &merged;</para>
|
|
|
|
<para>If a debugging kernel with modules is being built
|
|
(i.e. using <literal>makeoptions DEBUG=-g</literal>), the
|
|
modules will now be built with debugging support as well, for
|
|
completeness. A side effect of this change is that modules
|
|
built and installed with debugging kernels will now occupy more
|
|
space on disk than they did previously. &merged;</para>
|
|
|
|
<para>The kernel dump device can now be set via the
|
|
<varname>dumpdev</varname> loader tunable. As a result, it is
|
|
now possible to obtain crash dumps from panics during the late
|
|
stages of kernel initialization (before the system enters into
|
|
single-user mode). &merged;</para>
|
|
|
|
<sect3>
|
|
<title>Processor/Motherboard Support</title>
|
|
|
|
<para>SMP support has been largely reworked, incorporating code
|
|
from BSD/OS 5.0. One of the main features of SMPng
|
|
(<quote>SMP Next Generation</quote>) 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.</para>
|
|
|
|
<para arch="i386">Support for the 80386 processor has been
|
|
removed from the <filename>GENERIC</filename> kernel, as this
|
|
code seriously pessimizes performance on other IA32
|
|
processors.</para>
|
|
|
|
<para arch="i386">The <literal>I386_CPU</literal> 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.</para>
|
|
|
|
<para arch="i386">Custom kernels that will run on the 80386 can
|
|
still be built by changing the cpu options in the kernel

|
<literal>I386_CPU</literal>.</para>

|
|
<para arch="alpha">AlphaServer 1200 (<quote>Tincup</quote>) has

<filename>/dev/console</filename> output. &merged;</para>
|

hardcoded rules in the cases of a rules file in the

addition, the <literal>closed</literal> firewall type now works
|

as documented in the &man.rc.firewall.8; manual page. &merged;</para>
|
|
|
|
<para>The functionality of <filename>/etc/security</filename> has
|

<para arch="i386">&man.fdisk.8; no longer attempts to search for a

|
|
|
|
<para>&man.fdread.1;, a program to read data from floppy disks,
|
|
has been added. It is a counterpart to &man.fdwrite.1; and is

&man.dd.1;.</para>

<para>&man.find.1; now takes the <option>-iname</option> and

and the <option>-regexp</option> and <option>-iregexp</option>
|

<para>&man.fsck.8; wrappers have been imported; this feature

provides infrastructure for &man.fsck.8; to work on different

types of filesystems (analogous to &man.mount.8;).</para>
|
|
|
|
<para>The behavior of &man.fsck.8; when dealing with various

passes (a la <filename>/etc/fstab</filename>) has been modified
|
|
to accommodate multiple-disk filesystems.</para>
|
|
|
|
<para>&man.fsck.8; now has support for foreground
|
|
(<option>-F</option>) and background (<option>-B</option>)
|
|
checks. Traditionally, &man.fsck.8; is invoked before the
|
|
filesystems are mounted and all checks are done to completion at
|
|
that time. If background checking is available, &man.fsck.8; is
|
|
invoked twice. It is first invoked at the traditional time,
|
|
before the filesystems are mounted, with the <option>-F</option>
|
|
flag to do checking on all the filesystems that cannot do
|
|
background checking. It is then invoked a second time, after
|
|
the system has completed going multiuser, with the
|
|
<option>-B</option> flag to do checking on all the filesystems
|
|
that can do background checking. Unlike the foreground
|
|
checking, the background checking is started asynchronously so
|
|
that other system activity can proceed even on the filesystems
|
|
that are being checked. Boot-time enabling of this feature is
|
|
controlled by the
|
|
<varname>background_fsck</varname> option in &man.rc.conf.5;.</para>

|
|
|
<para>Shortly after the receipt of a <literal>SIGINFO</literal>

phase. &merged;</para>
|
|
|
|
<para>&man.fsck.ffs.8; now supports background filesystem checks
|
|
to mounted FFS filesystems with the <option>-B</option> option
|

<option>-F</option> flag now determines whether a specified

filesystem needs foreground checking.</para>
|
|

<para>A new &man.fsck.msdosfs.8; utility has been added to check

<para>&man.ftpd.8; now supports a <option>-r</option> flag for
|

read-only mode and a <option>-E</option> flag to disable

|
information leakage and the ability to specify compile-time port

ranges. &merged;</para>
|
|
|
|
<para>&man.ftpd.8; now supports <option>-o</option> and

<option>-O</option> options to disable the

<literal>RETR</literal> command; the former for everybody, and
|
|
the latter only for guest users. Coupled with

<option>-A</option> and appropriate file permissions, these can
|

be used to create a relatively safe anonymous FTP drop box for

others to upload to.</para>

|
<para>The &man.getprogname.3; and &man.setprogname.3; library

added. &merged;</para>

Naturally, this mechanism is only as secure as the contents of

<para>&man.pkg.sign.1; and &man.pkg.check.1; have been added to

<para>&man.pkg.update.1;, a utility to update installed packages

and update their dependencies, has been added. &merged;</para>

<para>&man.pkg.version.1; now has a version number comparison

routine that corresponds to the Porters Handbook. It also has

a <option>-t</option> option for testing address comparisons.

<para>&man.pkg.version.1; now takes a <option>-s</option> flag

<para>Version numbers of installed packages have a new

<varname>PORTREVISION</varname> and

<varname>PORTEPOCH</varname> variables in Ports Collection
|

<filename>Makefile</filename>s. These changes help keep track
|

of changes in the ports collection entries such as security

patches or &os;-specific updates, which aren't reflected in

the original, third-party software distributions.

&man.pkg.version.1; can now compare these new-style version

<para>To improve performance and disk utilization, the

<para>All packages and ports now contain an

<title>Upgrading from previous releases of &os;</title>

|
<para>If you're upgrading from a previous release of &os;, you
|
|
generally will have three options:
|
|
|
|
<itemizedlist>
|
|
<listitem>
|
|
<para>Using the binary upgrade option of &man.sysinstall.8;.
|
|
This option is perhaps the quickest, although it presumes
|
|
that your installation of &os; uses no special compilation
|
|
options.</para>
|
|
</listitem>
|
|
<listitem>
|
|
<para>Performing a complete reinstall of &os;. Technically,
|
|
this is not an upgrading method, and in any case is usually less
|
|
convenient than a binary upgrade, in that it requires you to
|
|
manually backup and restore the contents of
|
|
<filename>/etc</filename>. However, it may be useful in
|
|
cases where you want (or need) to change the partitioning of
|
|
your disks.
|
|
</listitem>
|
|
<listitem>
|
|
<para>From source code in <filename>/usr/src</filename>. This
|
|
route is more flexible, but requires more disk space, time,
|
|
and more technical expertise. Upgrading from very old
|
|
versions of &os; may be problematic; in cases like this, it
|
|
is usually more effective to perform a binary upgrade or a
|
|
complete reinstall.</para>

|
|
</para>
|
|
|

<para>Please read the <filename>INSTALL.TXT</filename> file for more

upgrade. If you are upgrading from source, please be sure to read
