The FreeBSD Project $FreeBSD$ 2000 2001 2002 2003 The FreeBSD Documentation Project The release notes for &os; &release.current; contain a summary of Both changes for kernel and userland are listed, as well as applicable security advisories that were issued since the last release. Some brief remarks on upgrading are also presented. This document contains the release notes for &os; &release.current; on the &arch.print; hardware platform. It describes recently added, changed, or deleted features of &os;. It also provides some notes on upgrading from previous versions of &os;. The &release.type; distribution to which these release notes apply represents a point along the &release.branch; development branch between &release.prev; and the future &release.next;. Some pre-built, binary &release.type; distributions along this branch can be found at . ]]> This distribution of &os; &release.current; is a &release.type; distribution. It can be found at or any of its mirrors. More information on obtaining this (or other) &release.type; distributions of &os; can be found in the Obtaining FreeBSD appendix to the FreeBSD Handbook. ]]> This section describes 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 &release.prev.historic; are also listed. 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. A remotely exploitable vulnerability in CVS has been corrected with the import of version 1.11.5. More details can be found in security advisory FreeBSD-SA-03:01. &merged; Support for the CanBe power management controller has been added. &merged; &man.devfs.5; is now mandatory; the NODEVFS option has been removed from the set of possible kernel configuration options. A second process scheduler, designed to be a general purpose scheduler with many SMP benefits, has been added to the scheduler framework. Exactly one scheduler must be specified in a kernel configuration. The original scheduler may be selected using options SCHED_4BSD. The newer (experimental) scheduler can be selected by using options SCHED_ULE. The alpha boot loader (boot1) can now be called boot for consistency with other platforms. The two parts of the boot loader (boot1 and boot2) have been combined into a single boot file, to simplify programs that need to write or otherwise manipulate the boot loader. The PC98 bootloader now has support for booting from SCSI MO media. &merged; A new module provides 802.11 link-layer support. The &man.wi.4; driver now uses this facility. A bug in TCP NewReno, which caused premature exit from fast recovery when NewReno was enabled, has been fixed. &merged; &man.geom.4; is now mandatory; the NO_GEOM has been removed from the set of kernel configuration options. Support has been added for volume labels on UFS and UFS2 filesystems. These labels are strings that can be used to identify a volume, regardless of what device it appears on. Labels can be set with the -L options to &man.newfs.8; or &man.tunefs.8;. With the GEOM_VOL module, volumes can be accessed using their labels under /dev/vol. The root filesystem can now be located on a &man.vinum.4; volume. More information can be found in the &man.vinum.4; manual page. The -N and -W flags to &man.disklabel.8; have been retired. &man.disklabel.8; is now only built for architectures where it is useful (i386, pc98, alpha, and ia64). The -s to &man.disklabel.8; has been removed because the i386 boot loader now resides in a single file. &man.dump.8; now supports caching of disk blocks with the -C option. This can improve dump performance at the cost of possibly missing filesystem updates that occur between passes. &man.dumpfs.8; now supports a -m flag to print file system parameters in the form of a &man.newfs.8; command. &man.elfdump.1;, a utility to display information about &man.elf.5; format executable files, has been added. &man.fetch.1; uses the .netrc support in &man.fetch.3; and also supports a -N to specify an alternate .netrc file. &man.fetch.3; now has support for .netrc files (see &man.ftp.1; for more details). &man.ftpd.8; now supports a -h option to disable printing any host-specific information, such as the &man.ftpd.8; version or hostname, in server messages. &merged; &man.ftpd.8; now supports a -P option to specify a port on which to listen in daemon mode. The default data port number is now set to be one less than the control port number, rather than being hard-coded. &merged; &man.ftpd.8; now supports an extended format of the /etc/ftpchroot file. Please refer to the &man.ftpchroot.5; manpage, which is now available, for details. &merged; &man.ftpd.8; now supports login directory pathnames that specify simultaneously a directory for &man.chroot.2; and that to change to in the chrooted environment. The /./ separator is used for this purpose, like in other FTP daemons having this feature. It may be used in both &man.ftpchroot.5; and &man.passwd.5;. &merged; &man.fwcontrol.8; now supports -R and -S options for receiving and sending DV streams. &merged; &man.ipfw.8; now supports enable and disable commands to control various aspects of the operation of &man.ipfw.4; (including enabling and disabling the firewall itself). These provide a more convenient and visible interface than the existing sysctl variables. &merged; &man.kenv.1; has been moved from /usr/bin to /bin to make it available at times during system startup when only the root filesystem is mounted. The MAKEDEV script is now unnecessary, due to the mandatory presence of &man.devfs.5;, and has been removed. The &man.libgeom.3; library has been added to allow some userland access to the &man.geom.4; subsystem. &man.newsyslog.8; now supports a W flag to force previously-started compression jobs for an entry (or group of entries specified with the G flag) to finish before beginning a new one. This feature is designed to prevent system overloads caused by starting several compression jobs on big files simultaneously. &merged; &man.pam.ssh.8; has been rewritten. One side effect of the rewrite is that it now starts a separate instance of &man.ssh-agent.1; for each session instead of trying to connect each session to the agent started by the first session. &man.ping.8; now supports a -D flag to set the Don't Fragment bit on outgoing packets. &man.ping.8; now supports a -z flag to set the Type of Service bits in outgoing packets. &man.pw.8; can now add a user whose name ends with a $ character; this change is intended to help administration of Samba services. &merged; The sunlabel utility, a program analogous to &man.disklabel.8; that works on Sun disk labels, has been added. The &man.swapoff.8; command has been added to disable paging and swapping on a device. A related &man.swapctl.8; command has been added to provide an interface to &man.swapon.8; and &man.swapoff.8; similar to other BSDs. The &man.swapoff.8; feature should be considered experimental. &man.syslogd.8; now allows multiple hosts or programs to be named in host or program specifications in &man.syslog.conf.5; files. &man.systat.1; now includes an -ifstat display mode that displays the network traffic going through active intrfaces on the system. &man.xargs.1; now supports a -P option to execute multiple copies of the same utility in parallel. awk from Bell Labs has been updated to a 13 December 2002 snapshot. BIND has been updated to version 8.3.4. &merged; All of the bzip2 suite of applications is now installed in the base system (in particular, bzip2recover is now built and installed. &merged; CVS has been updated to 1.11.5. &merged; FILEhas been updated to 3.40. GCC has been updated to 3.2.2 (release version). IPFilter has been updated to 3.4.31. The ISC DHCP client has been updated to 3.0.1RC11. libpcap now has support for selecting among multiple data link types on an interface. OpenPAM has been updated to the Daffodil release. OpenSSL has been updated to release 0.9.7. Among other features, this release includes support for AES and takes advantage of &man.crypto.4; devices. &merged; sendmail has been updated to version 8.12.7. &merged; &man.tcpdump.1; now supports a -L flag to list the data link types available on an interface and a -y to specify the data link type to use while capturing packages. Users with existing &os; systems are highly encouraged to read the Early Adopter's Guide to &os; 5.0. This document generally has the filename EARLY.TXT on the distribution media, or any other place that the release notes can be found. It offers some notes on upgrading, but more importantly, also discusses some of the relative merits of upgrading to &os; 5.X versus running &os; 4.X. Upgrading &os; should, of course, only be attempted after backing up all data and configuration files.
