$FreeBSD$What's NewThis section describes the most user-visible new or changed
features in &os; since &release.prev;. All changes
described here are unique to the &release.branch; branch unless
specifically marked as &merged; features.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.Kernel ChangesThe &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;Support for Intel's Wired for Management 2.0 (PXE)
was added to the FreeBSD boot loader. Due to API differences, the
older PXE versions are not supported. This allow network booting
using DHCP. &merged;Support for USB devices was added to the
GENERIC 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;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;A driver for AGP hardware has been added. &merged;The kernel and modules have been moved to the directory
/boot/kernel, so they can be easily
manipulated together. The boot loader has been updated to make
this change as seamless as possible.The i386 boot loader now has support for a
nullconsole
console type, for use on systems with neither a video console nor
a serial port. &merged;Replaced the PQ_*CACHE options with a
single PQ_CACHESIZE option to be set to
the cache size in kilobytes. The old options are still supported
for backwards compatibility. &merged;The NCPU, NAPIC,
NBUS, and NINTR kernel
configuration options, for configuring SMP kernels, have been
removed. NCPU is now set to a maximum of 16,
and the other, aforementioned options are now
dynamic. &merged;&man.devfs.5;, which allows entries in the
/dev 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 NODEVFS kernel option.Preliminary Cardbus support under NEWCARD has been added.
This code supports the TI113X, TI12XX, TI125X, Ricoh 5C46/5C47, Topic
95/97/100 and Cirrus Logic PD683X bridges. 16-bit PC Card support
is not yet functional.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;Extremely large swap areas (>67 GB) no longer panic the
system.The &man.ichsmb.4; driver for the Intel 82801AA
(ICH) SMBus controller and compatibles has been
added. &merged;The &man.uscanner.4; driver for basic USB scanner support
using SANE has been added. See the SANE home page for
supported scanners. The HP ScanJet 4100C, 5200C and 6300C are
known to be working.The umodem driver for USB modems has been added.
Support is provided for the 3Com 5605 and Metricom Ricochet GS
wireless USB modems.Support for threads under Linux emulation has been
added.The pccard driver and &man.pccardc.8; now support multiple
beep types upon card insertion and removal. &merged;A number of cleanups and enhancements have been applied to
the PCI subsystem.
/usr/share/misc/pci_vendors now contains a
vendor/device database, which can be used by
&man.pciconf.8;.The &man.spic.4; driver, which provides access to the job
dial device on some Sony laptops, has been added.PECOFF (WIN32 Execution file format) support has been
added.A VESA S3 linear framebuffer driver has been added.The buildkernel target now gets the
name of the configuration(s) to build from the
KERNCONF variable, not
KERNEL. It is no longer required, in some
cases, for a buildworld to precede a
buildkernel. (The
buildworld is still required when
upgrading across major releases, across
binutil upgrades and when &man.config.8;
changes version.)
The &man.random.4; device has been rewritten to use the
Yarrow 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
/var/db/entropy, as well as at
&man.shutdown.8; time.The &man.syscons.4; driver now supports keyboard-controlled
pasting, by default bound to
Shift-Insert.The &man.labpc.4; driver has been removed due to
bitrot.A new kernel option, options REGRESSION,
enables interfaces and functionality intended for use during
correctness and regression testing.The USER_LDT kernel option is now
activated by default.A new &man.ddb.4; command show pcpu lists
some of the per-CPU data.A new digi driver has been added to support PCI Xr-based and ISA
Xem Digiboard cards. A new digictl program is (mainly) used to
re-initialise cards that have external port modules attached such as
the PC/Xem.The O_DIRECT 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;OLDCARD and &man.pccardd.8; now support
PCI cards.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;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;Linker sets are now self-contained; &man.gensetdefs.8; is
unnecessary and has been removed.Numerous SMP-friendly changes have been made to the kernel's
mbuf allocator.The dgm driver has been removed in favor of the digi driver.Network device cloning has been implemented, and the &man.gif.4;
and &man.stf.4; devices have been modified to take advantage of it.
Thus, instead of specifying how many &man.gif.4; or &man.stf.4; devices
are available in kernel configuration files, &man.ifconfig.8;'s
option should be used when another device
instance is desired.The kernel message buffer is now accessible by the
(machine-independent) kern.msgbuf sysctl
variable; &man.dmesg.8; no longer needs to be SGID
kmem.A simple hash-based lookup optimization for large directories
called dirhash has been added. Conditional on the
UFS_DIRHASH kernel option, it improves the speed of
operations on very large directories at the expense of some
memory.Two new &man.ddb.4; commands, hwatch and
dhwatch, have been introduced. Analogous to
watch and dwatch, they install
hardware watchpoints (as opposed to software watchpoints) if supported
by the architecture.Support for Streaming SIMD
Extensions (SSE) has been introduced. The
CPU_ENABLE_SSE kernel option controls whether
support is compiled into the kernel.Processor/Motherboard SupportSMP 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.Support for the 80386 processor has been
removed from the GENERIC kernel, as this
code seriously pessimizes performance on other ia32
processors.The I386_CPU 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
I386_CPU.AlphaServer 1200 (Tincup) has
been tested and works OK. Currently it does not want to boot
from CD or floppy but a transplanted disk that was installed on
another Alpha works well. &merged;The API UP1100 mainboard has been verified to work.The API CS20 1U high server has been verified to work.The DEC3000 series support has been removed from the mfsroot
floppy image so that it fits on a 1.44 Mbyte floppy again. As the
DEC3000 is currently only usable diskless this should not cause
any problems.Support for AlphaServer 2100A (Lynx) has been
added.Kernel code has been added that allows older generation Alpha CPUs
(EV4 and EV5) to emulate instructions of the newer Alpha CPU
generations. This enables the use of binary-only programs like Adobe
Acrobat 4 on EV4 and EV5.SMP support for the alpha is now operational.Detection for new processors, such as the
FC-PGA2 Pentium III (Tualatin), Transmeta Crusoe, and Transmeta
Crusoe LongRun, has been added. &merged;Network Interface SupportAdded support for PCI Ethernet adapters based on the
National Semiconductor DP83815 chipset, including the NetGear
FA311-TX and FA312-TX, in the form of the &man.sis.4; driver.The &man.tap.4; driver, a virtual Ethernet device driver for
bridged configurations, has been added. &merged;The &man.ti.4; driver now supports the Alteon AceNIC
1000baseT Gigabit Ethernet and Netgear GA620T 1000baseT Gigabit
cards. &merged;The &man.xl.4; driver now supports the 3Com 3C556 and 3C556B
MiniPCI adapters used on some laptops. &merged;The &man.ed.4; driver is now supported.The &man.pcn.4; driver, which supports the AMD PCnet/FAST,
PCnet/FAST+, PCnet/FAST III, PCnet/PRO, PCnet/Home, and HomePNA
adapters, has been added. Although these cards are already
supported by the &man.lnc.4; driver, the &man.pcn.4; driver runs
these chips in 32-bit mode and uses the RX alignment feature to
achieve zero-copy receive. This driver is also
machine-independent, so it will work on both the i386 and alpha
platforms. The &man.lnc.4; driver is still needed to support non-PCI
cards. &merged;Support for Fujitsu MB86960A/MB86965A based Ethernet
PC-Cards is back. &merged;The snc driver for the National Semiconductor
DP8393X (SONIC) Ethernet controller has been added. Currently,
this driver is only used on the PC-98 architecture. &merged;The &man.an.4; driver for Cisco Aironet cards now supports
Wired Equivalent Privacy (WEP) encryption, settable via
&man.ancontrol.8;. &merged;The &man.el.4; driver can now be loaded as a
module.The &man.ray.4; driver, which supports the Webgear Aviator
wireless network cards, has been committed. The operation of
&man.ray.4; interfaces can be modified by
&man.raycontrol.8;. &merged;The &man.fpa.4; driver now supports Digital's
DEFPA FDDI adaptors on the Alpha.Linksys Fast Ethernet PCCARD cards supported by the
&man.ed.4; driver now require the addition of flag
0x80000 to their config line in
&man.pccard.conf.5;. This flag is not optional. These Linksys
cards will not be recognized without it.A bug in the &man.ed.4; driver that could cause panics with
very short packets and BPF or bridging active has been
fixed. &merged;The &man.fxp.4; driver now requires a device
miibus entry in the kernel configuration file. &merged;The &man.wx.4; driver now supports the Intel PRO1000-F and
PRO1000-T (10/100/1000) adapters. &merged;Added the &man.nge.4; driver, which supports PCI Gigabit
Ethernet adapters based on the National Semiconductor DP83820
and DP83821 Gigabit Ethernet controller chips, including the
D-Link DGE-500T, SMC EZ Card 1000 (SMC9462TX), Asante
FriendlyNet GigaNIC 1000TA and 1000TPC and Addtron
AEG320T. This driver supports transmit and receive checksum
offloading. &merged;The &man.lge.4; driver has been added to support the Level
1 LXT1001 NetCellerator Gigabit Ethernet controller chip. This
device is used on some fiber optic GigE cards from SMC, D-Link
and Addtron. Jumbograms and TCP/IP checksum offload on receive
are supported, although hardware VLAN filtering is not. &merged;The &man.xl.4; driver now supports reception of VLAN
tagged frames (on the Cyclone or newer
chipsets). &merged;The &man.ti.4; driver correctly masks VLAN tags. &merged;The &man.an.4; driver now supports the Cisco Aironet 350
series of adaptors.Network Protocols&man.accept.filter.9;, a kernel feature to reduce overheads
when accepting and reading new connections on listening sockets,
has been added. &merged;The &man.ng.mppc.4; and &man.ng.bridge.4; node types have
been added to the netgraph subsystem. The &man.ng.ether.4; node
is now dynamically loadable. Miscellaneous bug fixes and
enhancements have also been made. &merged;&man.netgraph.4; has received some updates and bugfixes.A new netgraph node type &man.ng.one2many.4; for multiplexing
and demultiplexing packets over multiple links has been added.
&merged;SLIP has been removed from the
mfsroot floppy image.ICMP ECHO and TSTAMP replies are now rate limited. TCP RSTs
generated due to packets sent to open and unopen ports are now
limited by separate counters. Each rate limiting queue now has
its own description.ICMP UNREACH_FILTER_PROHIB messages can
now RST TCP connections in the SYN_SENT state
if the correct sequence numbers are sent back, as controlled by the
net.inet.tcp.icmp_may_rst
sysctl.TCP has received some bug fixes for its delayed ACK
behavior. &merged;TCP now supports the NewReno modification to the TCP Fast Recovery
algorithm. This behavior can be controlled via the
net.inet.tcp.newreno sysctl variable. &merged;TCP now uses a more aggressive timeout for initial SYN segments; this
allows initial connection attempts to be dropped much
faster. &merged;The TCP_COMPAT_42 kernel option has
been removed.The TCP_RESTRICT_RST kernel option has
been removed. Similar functionality can be achieved with the
net.inet.tcp.blackhole sysctl
variable. &merged;TCP now has RFC 1323 extensions enabled by default in
&man.rc.conf.5;. &merged;RFC 1323 and RFC 1644 TCP extensions are now disabled for a
connection in progress if no response has been received by the
third SYN segment sent. This behavior tries to work around
(very old) terminal servers with buggy VJ header compression
implementations. &merged;The TCP implementation no longer requires the
allocation of a TCP template structure for each connection; this
should reduce the buffer usage on large systems handling many
connections. &merged;A new sysctl net.inet.ip.check_interface,
which is on by default, causes IP to verify that an incoming
packet arrives on an interface that has an address matching the
packet's destination address. &merged;A new sysctl
net.link.ether.inet.log_arp_wrong_iface has
been added to control the suppression of logging when ARP replies
arrive on the wrong interface. &merged;The proxy modifier to &man.arp.8;'s
option has been renamed to
pub, for consistency with the
option. The only keyword
has been added to the and
flags, to be used in creating
proxy-only published entries.&man.ipfw.8; now filters correctly in the presence of ECN bits in TCP
segments. &merged;&man.ipfw.8; will now avoid the display of dynamic
firewall rules unless the flag is passed to
it. The lists expired dynamic rules.&man.bridge.4; and &man.dummynet.4; have received some
enhancements and bug fixes.&man.ipfw.8; has a new feature (me) that
allows for packet matching on interfaces with dynamically-changing
IP addresses. &merged;&man.ip6fw.8; now has the ability to use a preprocessor
and use the (quiet) flag when reading from a
file. &merged;A new options RANDOM_IP_ID kernel
option causes the ID field of IP packets to be randomized. This
closes a minor information leak which allows a remote observer
to determine the rate at which the machine is generating
packets, since the default behaviour is to increment a counter
for each packet sent.IP multicast now works on VLAN devices. Several other
bugs in the VLAN code have also been fixed.Disks and StorageThe &man.twe.4; 3ware ATA RAID driver has added. &merged;The &man.ata.4; driver now has support for ATA100
controllers. In addition, it now supports the ServerWorks ROSB4
ATA33 chipset, the CMD 648 ATA66 and CMD 649 ATA100 chipsets, and
the Cyrix 5530. &merged;To provide more flexible configuration, the various options for the
&man.ata.4; driver are now boot loader tunables, rather than kernel
configure-time options. &merged;The &man.ata.4; driver now has support for tagged queuing,
which is enabled by the hw.ata.tags loader
tunable. &merged;The &man.ata.4; driver now has support for ATA
pseudo RAID controllers as the Promise Fasttrak and
HighPoint HPT370 controllers. &merged;The &man.mly.4; driver, for Mylex PCI to SCSI
AccelRAID and eXtremeRAID controllers with firmware 6.X and
later, has been added. &merged;The &man.asr.4; driver, which provides support
for the Adaptec SCSI RAID controller family, as well as the DPT
SmartRAID V and VI families, has been added. &merged;Support for the Adaptec FSA family of PCI-SCSI
RAID controllers has been added, in the form of the &man.aac.4;
driver.The &man.ahc.4; driver has received numerous updates,
bugfixes, and enhancements. Among various improvements are
improved compatibility with chips in RAID Port mode
and systems with AAA and/or ARO cards installed, as well as
performance improvements. Some bugs were also fixed, including a
rare hang on Ultra2/U160 controllers. &merged;The ncv, nsp, and stg drivers have
been ported from NetBSD/pc98. They support the NCR 53C50 /
Workbit Ninja SCSI-3 / TMC 18C30, 18C50 based PC-Card/ISA SCSI
controllers. &merged;The &man.cd.4; driver now has support for write operations.
This allows writing to DVD-RAM, PD and similar drives that probe
as CD devices. Note that change affects only random-access
writeable devices, not sequential-only writeable devices such as
CD-R drives, which are supported by &man.cdrecord.1; in the Ports
Collection. &merged;The &man.vinum.4; volume manager has received some bug fixes and
enhancements.&man.md.4;, the memory disk device, has had the
functionality of &man.vn.4; incorporated into it. &man.md.4;
devices can now be configured by &man.mdconfig.8;. &man.vn.4; has
been removed. The Memory Filesystem (MFS) has also been
removed.BurnProof(TM) support, for applicable ATAPI CD-ROM burners, is now
supported. &merged;A bug that made certain CDROM drives fail to
attach when connected to a SCSI card driven by &man.isp.4; has
been fixed. &merged;The &man.isp.4; driver is now proactive about discovering
Fibre Channel topology changes.The &man.isp.4; driver now supports target mode for Qlogic
SCSI cards, including Ultra2 and Ultra3 and dual bus cards.The ida disk driver now has crashdump support. &merged;The CAM error recovery code has been updated.Some problems in &man.sa.4; error handling have been
fixed, including the tape drive spinning indefinitely
upon mt stat problem.FilesystemsSupport for named extended attributes was added to the &os;
kernel. This allows the kernel, and appropriately privileged
userland processes, to tag files and directories with attribute
data. Extended attributes were added to support the TrustedBSD
Project, in particular ACLs, capability data, and mandatory access
control labels (see
/usr/src/sys/ufs/ufs/README.extattr for
details).Due to a licensing change, softupdates have been integrated
into the main portion of the kernel source tree. As a
consequence, softupdates are now available with the
GENERIC kernel. &merged;A filesystem snapshot capability has been added to FFS.
Details can be found in
/usr/src/sys/ufs/ffs/README.snapshot.Softupdates for FFS have received some bug fixes and
enhancements.When running with softupdates, &man.statfs.2; and
&man.df.1; will track the number of blocks and files that are
committed to being freed.A bug in FFS that could cause superblock corruption on very large
filesystems has been corrected. &merged;The Inode Filesystem (IFS) has been added; more information
can be found in
/usr/src/sys/ufs/ifs/README.The ISO-9660 filesystem now has a hook that supports a loadable
character conversion routine. The
sysutils/cd9660_unicode port
contains a set of common conversions.&man.kernfs.5; is obsolete and has been retired.A bug in the NFS client that caused bogus access times with
O_EXCL|O_CREAT opens was fixed. &merged;A new NFS hash function (based on the Fowler/Noll/Vo hash
algorithm) has been implemented to improve NFS performance by
increasing the efficiency of the nfsnode hash
tables. &merged;Client-side NFS locks have been implemented.Support for file system Access Control Lists (ACLs) has been
introduced, allowing more fine-grained control of discretionary
access control on files and directories. This support was
integrated from the TrustedBSD Project. More details can be found in
/usr/src/sys/ufs/ufs/README.acls.The directory layout preference algorithm for FFS has been
changed to improve its speed on large filesystems.smbfs (CIFS) support in kernel has been added.
The corresponding userland filesystem mount utility can be found
in the net/smbfs port in the &os; Ports
Collection. &merged;For consistency, the fdesc, fifo, null, msdos, portal,
umap, and union filesystems have been renamed to fdescfs,
fifofs, msdosfs, nullfs, portalfs, umapfs, and unionfs. Where
applicable, modules and mount_* programs have been
renamed. Compatability glue has been added to
&man.mount.8; so that msdos filesystem
entries in &man.fstab.5; will work without changes.pseudofs, a pseudo-filesystem framework, has been added.
&man.linprocfs.5; has been modified to use pseudofs.Multimedia SupportThe &man.pcm.4; driver now supports the ESS Solo 1,
Maestro-1, Maestro-2, and Maestro-2e; Forte Media fm801, ESS
Maestro-2e, and VIA Technologies VT82C686A sound card/chipsets,
and has received some other updates.
Separate drivers for the SoundBlaster 8 and Soundblaster 16 now
replace an older, unified driver. A driver for the CMedia
CMI8338/CMI8738 sound chips has been added. A driver for the
CS4281 sound chip has been added. A driver for the S3
Sonicvobes chipset has been added. &merged;A driver for the Advance Logic ALS4000 has
been added. &merged;A driver for the
ESS Maestro-3/Allegro has been added, however due to licensing
restrictions, it cannot be compiled into the kernel. &merged; To
use this driver, add the following line to
/boot/loader.conf:snd_maestro3_load="YES"The &man.bktr.4; driver has been updated to 2.18. This
update provides a number of new features: New tuner
types have been added, and improvements to the KLD module and to
memory allocation have been made. Bugs in &man.devfs.5; when
unloading and reloading have been fixed.
Support for new Hauppauge Model 44xxx WinTV Cards (the ones with
no audio mux) has been added.When sound modules are built, one can now load all the
drivers and infrastructure by kldload
snd.A new API has been added for sound cards with hardware
volume control.A driver for the Intel 443MX, 810, 815, and 815E
integrated sound devices has been added.Contributed SoftwareIPFilter has been updated to
3.4.16. &merged;The Forth Inspired Command Language
(FICL) used in the boot loader has
been updated to 2.05.ACPI support has been merged in from the
Intel ACPI
project, and updated to the ACPI CA 20010518 release.isdn4bsdisdn4bsd has been updated to
version 0.96.00.The &man.ihfc.4; driver for supporting Cologne Chip
Designs HFC devices under isdn4bsd
has been added.The &man.itjc.4; driver for supporting NETjet-S / Teles
PCI-TJ devices under isdn4bsd has
been added.Experimental support for the Eicon.Diehl DIVA 2.0 and
2.02 ISA PnP ISDN cards has been added to the &man.isic.4;
isdn4bsd driver.Active CAPI-based ISDN cards manufacured by AVM are now
supported using the &man.i4bcapi.4; and the &man.iavc.4; driver. The
supported cards are the AVM B1 PCI and AVM B1 ISA Basic Rate
cards and the AVM T1 Primary Rate cards.KAMEThe IPv6 stack is now based on a snapshot based on the KAME
Project's IPv6 snapshot as of 28 May, 2001. Most of the
items listed in this section are a result of this import.
lists userland updates to the
KAME IPv6 stack. &merged;&man.gif.4; is now based on RFC 2893, rather than RFC
1933. The IFF_LINK2 interface flag can
be used to control ingress filtering. &merged;IPSec has received some
enhancements, including the ability to use the Rijndael and
SHA2 algorithms. IPSec RC5 support has been removed due to
patent issues. &merged;&man.stf.4; now conforms to RFC 3056; the
IFF_LINK2 interface flag can be used to
control ingress filtering. &merged;IPv6 has better checking of illegal addresses (such as
loopback addresses) on physical networks. &merged;The IPV6_V6ONLY socket option is
now completely supported. The kernel's default behavior
with respect to this option is controlled by the
net.inet6.ip6.v6only sysctl
variable. &merged;RFC 3041 (Privacy Extensions for Stateless Address
Autoconfiguration) is now supported. It can be enabled via
the net.inet6.ip6.use_tempaddr sysctl
variable. &merged;Security Fixes&man.sysinstall.8; now allows the user to select one of three
security profiles at install-time. These profiles enable
different levels of system security by enabling or disabling
various system services in &man.rc.conf.5; on new
installs. &merged;A bug in which malformed ELF executable images can hang the
system has been fixed (see security advisory
FreeBSD-SA-00:41). &merged;A security hole in Linux emulation was fixed (see security
advisory FreeBSD-SA-00:42). &merged;&man.rlogind.8;, &man.rshd.8;, and &man.fingerd.8; are now
disabled by default in /etc/inetd.conf. This
only affects new installations. &merged;String-handling library calls in many programs were fixed to
reduce the possibility of buffer overflow-related exploits.
&merged;TCP now uses stronger randomness in choosing its initial sequence
numbers (see security advisory FreeBSD-SA-00:52). &merged;Several buffer overflows in &man.tcpdump.1; were corrected
(see security advisory FreeBSD-SA-00:61). &merged;A security hole in &man.top.1; was corrected (see security advisory
FreeBSD-SA-00:62). &merged;A potential security hole caused by an off-by-one-error in
&man.gethostbyname.3; has been fixed (see security advisory
FreeBSD-SA-00:63). &merged;A potential buffer overflow in the &man.ncurses.3; library,
which could cause arbitrary code to be run from within
&man.systat.1;, has been corrected (see security advisory
FreeBSD-SA-00:68). &merged;A vulnerability in &man.telnetd.8; that could cause it to
consume large amounts of server resources has been fixed (see
security advisory FreeBSD-SA-00:69). &merged;The nat deny_incoming command in
&man.ppp.8; now works correctly (see security advisory
FreeBSD-SA-00:70). &merged;A vulnerability in &man.csh.1;/&man.tcsh.1; temporary files
that could allow overwriting of arbitrary user-writable files has
been closed (see security advisory FreeBSD-SA-00:76). &merged;The &man.ssh.1; binary is no longer SUID root by
default.Some fixes were applied to the Kerberos
IV implementation related to environment variables, a
possible buffer overrun, and overwriting ticket files. &merged;&man.telnet.1; now does a better job of sanitizing its
environment. &merged;Several vulnerabilities in &man.procfs.5; were fixed (see
security advisory FreeBSD-SA-00:77). &merged;A bug in OpenSSH in which a
server was unable to disable &man.ssh-agent.1; or
X11Forwarding was fixed (see security advisory
FreeBSD-SA-01:01). &merged;A bug in &man.ipfw.8; and &man.ip6fw.8; in which inbound TCP
segments could incorrectly be treated as being part of an
established connection has been fixed (see
security advisory FreeBSD-SA-01:08). &merged;A bug in &man.crontab.1; that could allow users to read any
file on the system in valid &man.crontab.5; syntax has been fixed
(see security advisory FreeBSD-SA-01:09). &merged;A vulnerability in &man.inetd.8; that could allow
read-access to the initial 16 bytes of
wheel-accessible files has been fixed (see security
advisory FreeBSD-SA-01:11). &merged;A bug in &man.periodic.8; that used insecure temporary files has been
corrected (see security advisory FreeBSD-SA-01:12). &merged;A bug in &man.sort.1; in which an attacker might be able to
cause it to abort processing has been fixed (see security advisory
FreeBSD-SA-01:13). &merged;To fix a remotely-exploitable buffer overflow,
BIND has been updated
to 8.2.3 (see security advisory FreeBSD-SA-01:18). &merged;OpenSSH now has code to prevent
(instead of just mitigating through connection limits) an attack
that can lead to guessing the server key (not host key) by
regenerating the server key when an RSA failure is detected (see
security advisory FreeBSD-SA-01:24). &merged;A number of programs have had output formatting strings
corrected so as to reduce the risk of vulnerabilities. &merged;A number of programs that use temporary files now do so more
securely. &merged;A bug in ICMP that could cause an attacker to disrupt TCP and UDP
sessions has been corrected. &merged;A bug in &man.timed.8;, which caused it to crash if send
certain malformed packets, has been corrected (see security
advisory FreeBSD-SA-01:28). &merged;A bug in &man.rwhod.8;, which caused it to crash if send
certain malformed packets, has been corrected (see security
advisory FreeBSD-SA-01:29). &merged;A security hole in FreeBSD's FFS and EXT2FS implementations,
which allowed a race condition that could cause users to have
unauthorized access to data, has been fixed (see security advisory
FreeBSD-SA-01:30). &merged;A remotely-exploitable vulnerability in &man.ntpd.8; has
been closed (see security advisory FreeBSD-SA-01:31). &merged;A security hole in IPFilter's
fragment cache has been closed (see
security advisory FreeBSD-SA-01:32). &merged;Buffer overflows in &man.glob.3;, which could cause
arbitrary code to be run on an FTP server, have been closed. In
addition, to prevent some forms of DOS attacks, &man.glob.3;
allows specification of a limit on the number of pathname matches
it will return. &man.ftpd.8; now uses this feature (see security
advisory FreeBSD-SA-01:33). &merged;Initial sequence numbers in TCP are more thoroughly
randomized (see security advisory FreeBSD-SA-01:39). Due to some
possible compatability issues, the behavior of this security fix
can be enabled or disabled via the
net.inet.tcp.tcp_seq_genscheme sysctl
variable.&merged;The new net.inet.ip.maxfragpackets
and net.inet.ip.maxfragpackets sysctl
variables limit the amount of memory that can be consumed by IPv4
and IPv6 packet fragments, which defends against some denial of service
attacks. &merged;A vulnerability in the &man.fts.3; routines (used by
applications for recursively traversing a filesystem) could
allow a program to operate on files outside the intended directory
hierarchy. This bug has been fixed (see security advisory
FreeBSD-SA-01:40). &merged;&os;'s TCP implementation has been made more resistant to
SYN floods, by eliminating the RST segment normally sent when
removing a connection from the listen queue.OpenSSH now switches to the
user's UID before attempting to unlink the authentication
forwarding file, nullifying the effects of a race.A flaw allowed some signal handlers to remain in effect in a
child process after being exec-ed from its parent. This allowed
an attacker to execute arbitrary code in the context of a setuid
binary. This flaw has been corrected (see security advisory
FreeBSD-SA-01:42). &merged;Userland Changes&man.cdcontrol.1; now supports a cdid
command, which calculates and displays the CD serial number, using
the same algorithm used by the CDDB database. &merged;&man.mtree.8; now includes support for a file that lists
pathnames to be excluded when creating and verifying prototypes.
This makes it easier to use &man.mtree.8; as a part of an
intrusion-detection system. &merged;&man.ls.1; can produce colorized listings with the
flag (and appropriate terminal
support). &merged;&man.sysinstall.8; now properly preserves
/etc/mail during a binary upgrade. &merged;The &man.truncate.1; utility, which truncates or extends the length
of files, has been added. &merged;&man.syslogd.8; can take a option to
disable DNS queries for every request. &merged;&man.kenv.1;, a command to dump the kernel environment, has
been added. &merged;The behavior of &man.periodic.8; is now controlled by
/etc/defaults/periodic.conf and
/etc/periodic.conf. &merged;&man.boot98cfg.8;, a PC-98 boot manager installation and
configuration utility, has been added. &merged;&man.logger.1; can now send messages directly to a remote
syslog. &merged;&man.gdb.1; now supports hardware watchpoints (using the
kernel's debug register + support that has been introduced in
&os; 4.0). &merged;&man.which.1; is now a C program, rather than a Perl
script.&man.killall.1; is now a C program, rather than a Perl
script. As a result, its option now uses the
regular expression syntax of &man.regex.3;, rather than that of
&man.perl.1;. &merged;&man.killall.1; now allows non-root users to kill SUID root
processes that they started, the same as the Perl version did.&man.finger.1; now has the ability to support fingering
aliases, via the &man.finger.conf.5; file. &merged;&man.finger.1; now has support for a
.pubkey file.nsswitch support has been merged from NetBSD. By creating
an &man.nsswitch.conf.5; file, FreeBSD can be configured so that
various databases such as &man.passwd.5; and &man.group.5; can be
looked up using flat files, NIS, or Hesiod. The old
hosts.conf file is no longer used.RSA Security has waived all patent rights to the RSA
algorithm. As a
result, the native OpenSSL
implementation of the RSA algorithm is now activated by default,
and the rsaref port and
librsaUSA are no longer required for USA
residents. &merged;&man.ifconfig.8; command can set the link-layer address
of an interface. &merged;&man.ifconfig.8; can now accept addresses in slash/CIDR
notation. &merged;&man.ifconfig.8; now has support for setting parameters for
IEEE 802.11 wireless network devices. &man.wi.4; and
&man.an.4; devices are supported, and partial support is provided
for &man.awi.4; devices. &merged;&man.ifconfig.8; no longer displays the list of supported
media by default. Instead it displays it when the
is given. &merged;&man.setproctitle.3; has been moved from
libutil to
libc. &merged;&man.chio.1; now has the ability to specify elements by
volume tag instead of by their physical location as well as the
ability to return an element to its previous location. &merged;&man.sed.1; now takes a option for
extended regular expression support. &merged;&man.ln.1; now takes an option to
request user confirmation before overwriting an existing
file. &merged;&man.ln.1; now takes a flag to avoid
following a target that is a link, with a flag
for compatability with other implementations. &merged;Userland &man.ppp.8; has received a number of updates and
bug fixes. &merged;&man.make.1; has gained the :C///
(regular expression substitution), :L
(lowercase), and :U (uppercase) variable
modifiers. These were added to reduce the differences between the
&os; and
OpenBSD/NetBSD
&man.make.1 programs. &merged; Bugs in &man.make.1;, among which include broken null suffix
behavior, bad assumptions about current directory permissions, and
potential buffer overflows, have been fixed. &merged;The &os; Makefile infrastructure now
supports the WARNS directive from NetBSD. This
directive controls the addition of compiler warning flags to
CFLAGS in a relatively compiler-neutral
manner.&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;).The behavior of &man.fsck.8; when dealing with various
passes (a la /etc/fstab) has been modified to
accomodate multiple-disk filesystems.&man.style.perl.7;, a style guide for Perl code in the &os;
base system, has been added.The in use percentage metric displayed by
&man.netstat.1; now really reflects the percentage of network
mbufs used. &merged;&man.netstat.1; now has a flag that
tells it not to truncate addresses, even if they're too long for
the column they're printed in. &merged;&man.netstat.1; now keeps track of input and output packets
on a per-address basis for each interface. &merged;&man.netstat.1; now has a flag to reset
statistics.&man.sockstat.1; now has and
flags for listing connected and listening
sockets, respectively. &merged;&man.mergemaster.8; has gained some new features, has been
cleaned up somewhat, and is now more cross-platform friendly.&man.mergemaster.8; now sources an
/etc/mergemaster.rc file and also prompts the
user to run recommended commands (such as
newaliases) as needed. &merged;The compiler chain now uses the FSF-supplied C/C++ runtime
initialization code. This change brings about better
compatibility with code generated from the various egcs and gcc
ports, as well as the stock public FSF source. &merged;The threads library has gained some signal handling changes,
bug fixes, and performance enhancements (including zero system
call thread switching). &man.gdb.1; thread support has been
updated to match these changes. &merged;&man.chflags.1; has moved from /usr/bin
to /bin.Use of the CSMG_* macros no longer
require inclusion of
<sys/param.h>IP Filter is now supported by the
&man.rc.conf.5; boot-time configuration and
initialization. &merged;The &man.lastlogin.8; utility, which prints the last login
time of each user, has been imported from
NetBSD. &merged;&man.last.1; now implements a that
provides a snapshot of who was logged in at a
particular date and time&man.newfs.8; now implements write combining, which can make
creation of new filesystems up to seven times
faster. &merged;&man.newfs.8; now takes a option to
enable softupdates on a new filesystem. &merged;The default number of cylinders per group in &man.newfs.8;
is now 22, up from 16.A number of buffer overflows in &man.config.8; have been
fixed. &merged;&man.pwd.1; can now double as &man.realpath.1;, a program to
resolve pathnames to their underlying physical paths. &merged;&man.stty.1; now has support for an
erase2 control character, so that, for example,
both the Delete and Backspace
keys can be used to erase characters. &merged;The &man.ibcs2.8;, &man.linux.8;, &man.osf1.8;, and &man.svr4.8;
scripts, whose sole purpose was to load emulation
kernel modules, have been removed. The kernel module system will
automatically load them as needed to fulfill dependencies.&man.top.1; will now use the full width of its tty.&man.growfs.8;, a utility for growing FFS filesystems, has
been added. &man.ffsinfo.8;, a utility for dump all the
meta-information of an existing filesystem, has also been
added.&man.indent.1; has gained some new formatting
options. &merged;&man.sysinstall.8; now uses some more intuitive defaults
thanks to some new dialog support functions. &merged;The default root partition in &man.sysinstall.8; is now
100MB on the i386 and 120MB on the alpha.&man.xargs.1; gained a option which allows
the user to specify exactly where in the command line the input should
be retrofitted. &merged;Shortly after the receipt of a SIGINFO
signal (normally control-T from the controlling tty), &man.fsck.ffs.8;
will now output a line indicating the current phase number and
progress information relevant to the current phase. &merged;&man.fsck.ffs.8; now supports background filesystem checks
to mounted FFS filesystems with the option
(softupdates must be enabled on these filesystems). The
flag now determines whether a specified
filesystem needs foreground checking.&man.fsck.8; now has support for foreground
() and background () 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 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 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
background_fsck option in &man.rc.conf.5;.A new &man.fsck.msdosfs.8; utility has been added to check
the consistency of MS-DOS filesystems.Catching up with most other network utilities in the base
system, &man.lpr.1;, &man.lpd.8;, &man.syslogd.8;, and
&man.logger.1; are now all IPv6-capable. &merged;libdisk can now do
install-time configuration of the &arch; boot0
boot loader. &merged;The option to &man.rm.1; now displays
the entire pathname of a file being removed.&man.lpr.1;, &man.lpq.1;, and &man.lpd.8; have received a
few minor enhancements. &merged;&man.lpd.8; now takes two new options:
will log all connection errors to &man.syslogd.8;, while
will allow connections from non-reserved
ports. &merged;&man.lpc.8; has been improved; lpc clean
is now somewhat safer, and a new lpc tclean
command has been added to check to see what files would be removed
by lpc clean. &merged;If the first argument to &man.ancontrol.8; or
&man.wicontrol.8; doesn't start with a -, it is
assumed to be an interface.&man.rdist.1; has been retired.&man.ppp.8; has gained the tcpmssfixup
option, which adjusts outgoing TCP SYN packets so that the maximum
receive segment size is no larger than allowed by the interface
MTU.libcrypt and
libdescrypt have been unified to provide a
configurable password authentication hash library. Both the md5
and des hash methods are provided unless the des hash is
specifically compiled out.&man.passwd.1; and &man.pw.8; now select the password hash
algorithm at run time. See the passwd_format
attribute in /etc/login.conf.In preparation for meeting SUSv2/POSIX
<sys/select.h> requirements,
struct selinfo and related functions have been
moved to <sys/selinfo.h>.&man.syslogd.8; now supports a LOG_CONSOLE
facility (disabled by
default), which can be used to log /dev/console
output. &merged;&man.rpcgen.1; now uses /usr/bin/cpp
(as on NetBSD), not /usr/libexec/cpp.Boot-time &man.syscons.4; configuration was moved to a
machine-independent /etc/rc.syscons. &merged;&man.burncd.8; now supports a option for
multisession mode (the default behavior now is to close disks as
single-session). A option to take a list of
image files from a filename was also added; -
can be used as a filename for stdin. &merged;&man.dmesg.8; now has a option to show
the entire message buffer, including &man.syslogd.8; records and
/dev/console output. &merged;&man.cdcontrol.1; now uses the CDROM
environment variable to pick a default device. &merged;&man.cdcontrol.1; now supports next and
prev commands to skip forwards or backwards a
specified number of tracks while playing an audio CD.&man.sysctl.8; now supports a option to
print out variable names only.&man.sysctl.8; has replaced the and
options with and
respectively; the former options are now
deprecated. The is deprecated as well; it is
not needed to determine the user's intentions.&man.sysinstall.8; now lives in /usr/sbin,
which simplifies the installation process. The &man.sysinstall.8;
manpage is also installed in a more consistent fashion now.&man.config.8; is now better about converting various
warnings that should
have been errors into actual fatal errors with an exit code. This
ensures that make buildkernel
doesn't quietly ignore them and
build a bogus kernel without a human to read the errors. &merged;libc is now thread-safe by default;
libc_r contains only thread functions.&man.find.1; now takes the flag,
which returns true if a file or directory is empty. &merged;&man.find.1; now takes the and
primaries for case-insensitive matches,
and the and
primaries for regular-expression matches. The
flag now enables extended regular expressions. &merged;&man.find.1; now has the ,
, ,
, and
primaries for comparisons of file timestamps. &merged;&man.tftpd.8; now takes the and
options, which allow the server to
&man.chroot.2; based on the IP address of the connecting client.
&man.tftp.1; and &man.tftpd.8; can now transfer files larger than
65535 blocks. &merged;&man.vidcontrol.1; now accepts a
parameter to select custom text geometry in the
VESA_800x600 raster text mode. &merged;&man.ldconfig.8; now checks directory ownerships and
permissions for greater security; these checks can be disabled
with the flag. &merged;The &man.rfork.thread.3; library call has been added as a
helper function to &man.rfork.2;. Using this function should
avoid the need to implement complex stack swap
code. &merged;Significant additions have been made to internationalization
support; &os; now has complete locale support for the
LC_MONETARY, LC_NUMERIC, and
LC_MESSAGES categories. A number of
applications have been updated to take advantage of this
support.Locale names have been changed to improve compatability with
the names used by X11R6, as well as a number of other UNIX
versions. As an example, the en_US.ISO_8859-1
locale name has been changed to
en_US.ISO8859-1. Entries in
/etc/locale.alias provide backward
compatability.A compat4x distribution has been added
for compatibility with &os; 4-STABLE.The
compat3x distribution has been updated to
include libraries present in &os; 3.5.1-RELEASE. &merged;&man.savecore.8; now supports a option
to prevent clearing a crash dump after saving it. It also
attempts to avoid writing large stretches of zeros to crash dump
files to save space and time. &merged;&man.savecore.8; now works correctly on machines with 2 GB
or more of RAM. &merged;&man.tar.1; now supports the TAR_RSH
variable, principally to enable the use of &man.ssh.1; as a
transport. &merged;&man.disklabel.8; now supports partition sizes expressed in
kilobytes, megabytes, or gigabytes, in addition to sectors. &merged;The pseudo-random number generator implemented by
&man.rand.3; has been improved to provide less biased results.&man.login.1; now exports environment variables set by
PAM modules. &merged;PAM support has been added for
account management and sessions.&man.su.1; now uses PAM for
authentication.&man.wall.1; now supports a flag to
write a message to all users of a given group.The new CPUTYPEmake.conf variable controls the compilation
of processor-specific optimizations in various pieces of code such
as OpenSSL. &merged;The default value for &man.cvs.1;'s
CVS_RSH variable is now ssh,
rather than rsh. &merged;&man.ipfstat.8; now supports the option
to turn on a &man.top.1;-like display. &merged;/usr/src/share/examples/BSD_daemon/ now
contains a scalable Beastie graphic. &merged;&man.dump.8; now supports inheritance of the
nodump flag down a hierarchy. &merged;The to &man.dump.8; no longer swallows
an extra argument. &merged;&man.dump.8; has a new option, allowing
the path to the /etc/dumpdates file to be
changed. &merged;&man.split.1; now has the ability to split a file longer
than 2GB. &merged;&man.tail.1; now has the ability to work on files longer
than 2GB. &merged;&man.units.1; has received some updates and bugfixes. &merged;As part of an ongoing process, many manual pages were
improved, both in terms of their formatting markup and in their
content. &merged;lprm - now works for remote printer
queues. &merged;&man.ftpd.8; now supports a flag for
read-only mode and a flag to disable
EPSV. It also has some fixes to reduce
information leakage and the ability to specify compile-time port
ranges. &merged;&man.ping.8; now supports a option to
set the TTL of outgoing packets. &merged;&man.ping.8; now supports a option to
beep when packets are lost.A version of Transport Independent RPC
(TI-RPC) has been imported.&man.rpcbind.8; has replaced &man.portmap.8;.NFS now works over IPv6.&man.rpc.lockd.8; has been imported from NetBSD.&man.rc.8; now has an framework for handling dependencies between
&man.rc.conf.5; variables. &merged;&man.rc.8; now deletes all non-directory files in
/var/run and
/var/spool/lock at boot time.The &man.setfacl.1; and &man.getfacl.1; commands have been
added to manage file system Access Control Lists.The default TCP port range used by
libfetch for passive FTP retrievals has
changed; this affects the behavior of &man.fetch.1;, which has
gained the option to restore the old
behavior. &merged;libfetch now has support for an
authentication callback.
libfetch now has support for a
HTTP_USER_AGENT environment variable. &merged;&man.atacontrol.8; has been added to control various aspects
of the &man.ata.4; driver.libcrypt now has support for Blowfish
password hashing. &merged;The functions from libposix1e have been
integrated into libc.&man.vidcontrol.1; now allows the user to omit the font size
specification when loading a font, and has some better
error-handling. &merged;&man.vidcontrol.1; now supports a to
take a snapshot of a &man.syscons.4; video buffer. These
snapshots can be manipulated by some of the
scr2* utilities in the Ports
Collection. &merged;&man.vidcontrol.1; now supports a option
to clear the history buffer for a given tty.devinfo, a simple tool to print the device tree and resource usage by
devices, has been added.&man.fmtcheck.3;, a function for checking consistency of
format string arguments, has been added.&man.nl.1;, a line numbering filter program, has been added.&man.c89.1; has been converted from a shell script to a
binary executable, fixing some minor bugs. &merged;&man.pax.1; has received a number of enhancements, including
&man.cpio.1; functionality, &man.tar.1; compatability
enhancements, and flags
for &man.gzip.1; and &man.compress.1; functionality, and a number
of bug fixes.Ukranian language support has been added to the &os;
console. &merged;The performance of the ELF dynamic linker &man.rtld.1; has
been improved. &merged;&man.fdread.1;, a program to read data from floppy disks,
has been added. It is a counterpart to &man.fdwrite.1; and is
designed to provide a means of recovering at least some data from
bad media, and to obviate for a complex invocation of
&man.dd.1;.&man.xargs.1; now supports a
replstr option that allows the user to
tell &man.xargs.1; to insert the data read from standard input at
a specific point in the command line arguments rather than at the
end.&man.apmd.8; now supports monitoring of the battery state via the
apm_battery configuration directive.&man.telnet.1; now does autologin and encryption by default;
a new option turns off encryption.&man.telnet.1; now supports a flag to

only) are used together.&man.whois.1; now directs queries for IP addresses to
ARIN. &merged; If a query to ARIN references APNIC or RIPE, the
appropriate server will also be queried, provided that the
is not specified.A new utility &man.diskcheckd.8; has been added; it is a
daemon which runs in the background, reading entire disks to find
any read errors on those disks. Its behavior at startup time can
be controlled by the diskcheckd_enable variable
in &man.rc.conf.5;.&man.fmt.1; has been rewritten; the rewrite fixes a number
of bugs compared to its prior behavior.&man.df.1; now takes a option to only
display information about locally-mounted filesystems. &merged;The syntax of &man.inetd.8;'s support for &man.faithd.8; is
now compatable with that of other BSDs. &merged;The ident protocol support in &man.inetd.8; has
been cleaned up and updated.&man.inetd.8; now has the ability to manage UNIX-domain
sockets.&man.du.1; now takes a command-line flag
to ignore/skip files and subdirectories matching a specified

deprecated &man.mount.mfs.8;.The &man.getprogname.3; and &man.setprogname.3; library
functions have been added to manipulate the name of the current
program. They are used by error-reporting routines to produce
consistent output. &merged;The &man.kldconfig.8; utility has been added to make it easier to
manipulate the kernel module search path.&man.moused.8; now takes a to control
mouse acceleration.&man.fdisk.8; no longer attempts to search for
a device if none has been specified on the command line, but
instead tries to figure out the default device name from the
root device.Contributed Softwarebc has been updated from 1.04 to
1.06. &merged;The ISC library from the BIND

GCC_OPTIONS, which can hold a set of default
options for GCC.GNATS has been updated to
3.113.gperf has been updated to 2.7.2.groff and its related utilities
have been updated to FSF version 1.17.2. This import brings in a

mdocNG), which removes many of the
limitations of its predecessor. &merged;Heimdal has been updated to
0.3f.The ISC DHCP client has been
updated to 2.0pl5. &merged;Kerberos IV has been updated to

&man.gifconfig.8;. &merged;&man.ifconfig.8; can now perform the functions of
&man.prefix.8;. &man.prefix.8; is now a shell script for
partial backwards compatability. &merged;&man.ndp.8; now implements garbage collection for stale
NDP entries, as described in RFC 2461 (Neighbor Discovery for
IP Version 6 (IPv6)). &merged;&man.pim6dd.8; and &man.pim6sd.8; have been removed due to
restrictive licensing conditions. These programs are available
in the ports collection as net/pim6dd and
net/pim6dd. &merged;&man.route6d.8; now supports a flag
to avoid updating the kernel forwarding table. &merged;The (router renumbering) option to
&man.rtadvd.8; is currently ignored. &merged;OpenSSHOpenSSH has been upgraded to
2.1.0, which provides support for the SSH2 protocol, including DSA
keys. Therefore, OpenSSH users in the
US no longer need to rely on the restrictively-licensed
RSAREF toolkit which is required to
handle RSA keys. OpenSSH 2.1 interoperates well with other SSH2
clients and servers, including the ssh2 port.
See the OpenSSH Web
site for more details. &merged;OpenSSH can now authenticate
using OPIE passwords in SSH1 mode. Support is not yet available
in SSH2 mode. &merged;OpenSSH has been upgraded to
2.2.0. &man.ssh-add.1; and &man.ssh-agent.1; can now handle DSA
keys. A server for sftp, interoperable with ssh.com
clients and others has been added. &man.scp.1; can now handle
files larger than 2 GBytes. Interoperability with other SSH2
clients/servers has been improved. A new feature to limit the
number of outstanding unauthenticated ssh connections in
&man.sshd.8; has been added. &merged;OpenSSH has been upgraded to
2.3.0. This version adds support for the Rijndael encryption
algorithm. &merged;PAM support for
OpenSSH has been added.A long-standing bug in OpenSSH,
which sometimes resulted in a dropped session when an
X11-forwarded client was closed, was fixed.Kerberos compatability has been
added to OpenSSH. &merged;OpenSSH has been modified to be
more resistant to traffic analysis by requiring that
non-echoed characters are still echoed back in a
null packet, as well as by padding passwords sent so as not to
hint at password lengths. &merged;&man.sshd.8; is now enabled by default on new
installs. &merged;&man.sshd.8; X11Forwarding is now turned
on by default on the server (any risk is to the client, where it
is already disabled by default).In /etc/ssh/sshd_config, the
ConnectionsPerPeriod parameter has been
deprecated in favor of MaxStartups.OpenSSH now has a
VersionAddendum configuration setting for
&man.sshd.8; to allow changing the part of the
OpenSSH version string after the
main version number.OpenSSH has been updated to
version 2.9, which adds two new programs, &man.sftp.1; and
&man.ssh-keyscan.1;. Among the various enhancements: The
default protocol is now v2, rekeying of existing SSH sessions
is now supported, and an experimental
SOCKS4 proxy has been added to
&man.ssh.1;.OpenSSLOpenSSL has been upgraded to
0.9.6a. &merged;OpenSSL now has support for
machine-dependent ASM optimizations, activated by the new
MACHINE_CPU and/or CPUTYPEmake.conf variables. &merged;sendmailsendmail has been upgraded from
version 8.9.3 to version 8.11.4. Important changes include: new
default file locations (see
/usr/src/contrib/sendmail/cf/README);
&man.newaliases.1; is limited to root and
trusted users; STARTTLS encryption; and the MSA port (587) is
turned on by default. See
/usr/src/contrib/sendmail/RELEASE_NOTES for
more information. &merged;&man.mail.local.8; is no longer installed as a SUID binary.
If you are using a /etc/mail/sendmail.cf from
the default sendmail.cf included with &os;
any time after 3.1.0, you are fine. If you are using a
hand-configured sendmail.cf and
mail.local for delivery, check to make sure the
F=S flag is set on the
Mlocal line. Those with
.mc files who need to add the flag can do so
by adding the following line to their .mc
file and regenerating the sendmail.cf
file:MODIFY_MAILER_FLAGS(`LOCAL',`+S')dnlNote that FEATURE(`local_lmtp') already
does this. &merged;The default /etc/mail/sendmail.cf
disables the SMTP EXPN and
VRFY commands. &merged;&man.vacation.1; has been updated to use the version included with
sendmail. &merged;The sendmail configuration
building tools are installed in
/usr/share/sendmail/cf/. &merged;New make.conf options:
SENDMAIL_MC and
SENDMAIL_ADDITIONAL_MC. See
/etc/defaults/make.conf for more
information. &merged;/etc/mail/Makefile now supports: the
new SENDMAIL_MCmake.conf
option; the ability to build .cf files from
.mc files; generalized map rebuilding;
rebuilding the aliases file; and the ability to stop, start, and
restart sendmail. &merged;Ports/Packages CollectionVersion numbers of installed packages have a new
(backward-compatible) syntax, which supports the
PORTREVISION and PORTEPOCH
variables in Ports Collection Makefiles.
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 numbers. &merged;To improve performance and disk utilization, the ports
skeletons in the FreeBSD Ports Collection have been restructured.
Installed ports and packages should not be affected. &merged;All packages and ports now contain an origin
directive, which makes it easier for programs such as
&man.pkg.version.1; to determine the directory from which a
package was built. &merged;&man.pkg.update.1;, a utility to update installed packages
and update their dependencies, has been added. &merged;&man.pkg.info.1; now supports globbing against names of
installed packages. The option disables this
behavior, and the option causes regular
expression matching instead of shell globbing. &merged;&man.pkg.info.1; can now accept a flag for
verifying an installed package against its recorded checksums (to
see if it's been modified post-installation). Naturally, this
mechanism is only as secure as the contents of
/var/db/pkg if it's to be used for auditing
purposes. &merged;&man.pkg.create.1; and &man.pkg.add.1; can now work with
packages that have been compressed using
&man.bzip2.1;. &man.pkg.add.1; will use the PACKAGEROOT
environment variable to determine a mirror site for new
packages. &merged;&man.pkg.create.1; now records dependencies in dependency
order rather than in the order specified on the command line.
This improves the functioning of pkg_add
-r. &merged;&man.pkg.version.1; now has a version number comparison
routine that corresponds to the Porters Handbook. It also has a
option for testing address comparisons.
&merged;&man.pkg.version.1; now takes a flag
to limit its operation to ports/packages matching a given
string. &merged;When requested to delete multiple packages,
&man.pkg.delete.1; will now attempt to remove them in dependency
order rather than the order specified on the command
line. &merged;&man.pkg.delete.1; now can perform glob/regexp matching of
package names. In addition, it supports a
option for removing all packages and a option
for &man.rm.1;-style interactive confirmation. &merged;&man.pkg.sign.1; and &man.pkg.check.1; have been added to
digitally sign and verify the signatures on binary package
files. &merged;BSDPAN, a collection of modules
that provides tighter integration of
Perl into the &os; Ports
Collection, has been added.
