Finally, after a few days of mirror syncing and documentation preparation, The FreeBSD Release Engineering (RELENG) Team finally decided to announce the availability of FreeBSD 8.0!
The source code for 8.0 was got it’s final touches during the weekend, and on Sunday I had the oportunity to upgrade my server to the latest and greatest. After some upgrade jiffies conserning migration and upgrade of my experimental ZFS filesystem setup, everything seems to work without a hitch.
The only notable showstopper I know about this far is the breakage of the fxp network interface driver, which was not ready in time for release. This will probably be fixed within a week or two, I assume.
It’s a relief to have upgraded to ZFS v13, by the way. Finally I can start trusting my now nearly 3TB striped storage setup :-).
System information about the currently running system on my own server can be found at http://grimstveit.no/admin/phpsysinfo.
The highlights in the 8.0-RELEASE are the following:
- A new virtualization container named â€œvimageâ€ has been implemented. This is a jail with a virtualized instance of the FreeBSD network stack and can be created by using jail(8) command.
- The FreeBSD netisr framework has been reimplemented for parallel threading support. This is a kernel network dispatch interface which allows device drivers (and other packet sources) to direct packets to protocols for directly dispatched or deferred processing. The new implementation supports up to one netisr thread per CPU, and several benchmarks on SMP machines show substantial performance improvement over the previous version.
- The FreeBSD TTY layer has been replaced with a new one which has better support for SMP and robust resource handling. A tty now has own mutex and it is expected to improve scalability when compared to the old implementation based on the Giant lock.
- [amd64, i386] The FreeBSD Linux emulation layer has been updated to version 2.6.16 and the default Linux infrastructure port is now emulators/linux_base-f10 (Fedora 10).
- The FreeBSD GENERIC kernel now includes Trusted BSD MAC (Mandatory Access Control) support. No MAC policy module is loaded by default.
- The FreeBSD USB subsystem has been reimplemented to support modern devices and better SMP scalability. The new implementation includes Giant-lock-free device drivers, a Linux compatibility layer, usbconfig(8) utility, full support for split transaction and isochronous transaction, and so on.
- The FreeBSD CAM SCSI subsystem ( cam(4)) now includes experimental support for ATA/SATA/AHCI-compliant devices.
- The shared vnode locking for pathname lookups in the VFS(9) subsystem has been improved.
- The ZFS file system has been updated to version 13. The changes include ZFS operations by a regular user, L2ARC, ZFS Intent Log on separated disks (slog), sparse volumes, and so on.
- The FreeBSD NFS subsystem now supports RPCSEC_GSS authentication on both the client and server.
- The FreeBSD NFS subsystem now includes a new, experimental implementation with support for NFSv2, NFSv3, and NFSv4.
- The wireless network support layer (net80211) now supports multiple BSS instances on the supported network devices.
- The FreeBSD L2 address translation table has been reimplemented to reduce lock contention on parallel processing and simplify the routing logic.
- The IGMPv3 and SSM (Source-Specific Multicast) including IPv6 SSM and MLDv2 have been added.
- The ipsec(4) subsystem now supports NAT-Traversal (RFC 3948).
- The GCC stack protection (also known as ProPolice) has been enabled in the FreeBSD base system.
- The supported version of the GNOME desktop environment (x11/gnome2) has been updated to 2.26.3.
- The supported version of the KDE desktop environment (x11/kde4) has been updated to 4.3.1.
Official announcement follows:
The FreeBSD Release Engineering Team is pleased to announce the availability of FreeBSD 8.0-RELEASE. This release starts off the new 8-STABLE branch which improves on the functionality of FreeBSD 7.X and introduces many new features. Some of the highlights: - Xen Dom-U, VirtualBox guest and host, hierarchal jails - NFSv3 GSSAPI support, experimental NFSv4 client and server - 802.11s D3.03 wireless mesh networking and Virtual Access Point support - ZFS no longer in experimental status - ground-up rewrite of USB, including USB target support - continued SMP scalability improvements in many areas, especially VFS - revised network link layer subsystem - experimental MIPS architecture support For a complete list of new features and known problems, please see the online release notes and errata list, available at: http://www.FreeBSD.org/releases/8.0R/relnotes.html http://www.FreeBSD.org/releases/8.0R/errata.html For more information about FreeBSD release engineering activities, please see: http://www.FreeBSD.org/releng/ Dedication ---------- The FreeBSD Project dedicates this release to the memories of Jean-Marc Zucconi (jmz@) and John Birrell (jb@) who passed away in May and November of 2009 respectively. Jean-Marc and John were both FreeBSD committers since the mid-1990s and made extensive contributions to the operating system. They will be missed. Availability ------------- FreeBSD 8.0-RELEASE is now available for the amd64, i386, ia64, pc98, powerpc, and sparc64 architectures. FreeBSD 8.0 can be installed from bootable ISO images or over the network. Some architectures (currently amd64 and i386) also support installing from a USB memory stick. The required files can be downloaded via FTP or BitTorrent as described in the sections below. While some of the smaller FTP mirrors may not carry all architectures, they will all generally contain the more common ones such as amd64 and i386. MD5 and SHA256 hashes for the release ISO and memory stick images are included at the bottom of this message. The purpose of the images provided as part of the release are as follows: dvd1: This contains everything necessary to install the base FreeBSD operating system, a collection of pre-built packages, and the documentation. It also supports booting into a "livefs" based rescue mode. This should be all you need if you can burn and use DVD-sized media. disc1: This contains the base FreeBSD operating system and the documentation packages for CDROM-sized media. There are no other packages. livefs: This contains support for booting into a "livefs" based rescue mode but does not support doing an install from the CD itself. It is meant to help rescue an existing system but could be used to do a network based install if necessary. bootonly: This supports booting a machine using the CDROM drive but does not contain the support for installing FreeBSD from the CD itself. You would need to perform a network based install (e.g. from an FTP server) after booting from the CD. memstick: This can be written to an USB memory stick (flash drive) and used to do an install on machines capable of booting off USB drives. It also supports booting into a "livefs" based rescue mode. The documentation packages are provided but no other packages. As one example of how to use the memstick image, assuming the USB drive appears as /dev/da0 on your machine something like this should work: # dd if=8.0-RELEASE-amd64-memstick.img of=/dev/da0 bs=10240 conv=sync Be careful to make sure you get the target (of=) correct. FreeBSD 8.0-RELEASE can also be purchased on CD-ROM or DVD from several vendors. One of the vendors that will be offering FreeBSD 8.0-based products is: ~ FreeBSD Mall, Inc. http://www.freebsdmall.com/ BitTorrent ---------- 8.0-RELEASE ISOs are available via BitTorrent. A collection of torrent files to download the images is available at: http://torrents.freebsd.org:8080/ FTP --- At the time of this announcement the following FTP sites have FreeBSD 8.0-RELEASE available. ftp://ftp.freebsd.org/pub/FreeBSD/ ftp://ftp1.freebsd.org/pub/FreeBSD/ ftp://ftp5.freebsd.org/pub/FreeBSD/ ftp://ftp10.freebsd.org/pub/FreeBSD/ ftp://ftp13.freebsd.org/pub/FreeBSD/ ftp://ftp14.freebsd.org/pub/FreeBSD/ ftp://ftp.br.freebsd.org/pub/FreeBSD/ ftp://ftp.cz.freebsd.org/pub/FreeBSD/ ftp://ftp.dk.freebsd.org/pub/FreeBSD/ ftp://ftp.fr.freebsd.org/pub/FreeBSD/ ftp://ftp.jp.freebsd.org/pub/FreeBSD/ ftp://ftp.ru.freebsd.org/pub/FreeBSD/ ftp://ftp1.ru.freebsd.org/pub/FreeBSD/ ftp://ftp.tw.freebsd.org/pub/FreeBSD/ ftp://ftp4.tw.freebsd.org/pub/FreeBSD/ ftp://ftp.uk.freebsd.org/pub/FreeBSD/ ftp://ftp1.us.freebsd.org/pub/FreeBSD/ ftp://ftp5.us.freebsd.org/pub/FreeBSD/ ftp://ftp10.us.freebsd.org/pub/FreeBSD/ However before trying these sites please check your regional mirror(s) first by going to: ftp://ftp..FreeBSD.org/pub/FreeBSD Any additional mirror sites will be labeled ftp2, ftp3 and so on.

It provides a complete installation walk-through for users new to FreeBSD, and can be found online at: http://www.FreeBSD.org/doc/en_US.ISO8859-1/books/handbook/install.html Updates from Source ------------------- The procedure for doing a source code based update is described in the FreeBSD Handbook: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/synching.html http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html The branch tag to use for updating the source is RELENG_8_0. FreeBSD Update -------------- The freebsd-update(8) utility supports binary upgrades of i386 and amd64 systems running earlier FreeBSD releases. Systems running 7.-RELEASE, 8.0-BETA, or 8.0-RC can upgrade as follows: # freebsd-update upgrade -r 8.0-RELEASE During this process, FreeBSD Update may ask the user to help by merging some configuration files or by confirming that the automatically performed merging was done correctly. # freebsd-update install The system must be rebooted with the newly installed kernel before continuing. # shutdown -r now After rebooting, freebsd-update needs to be run again to install the new userland components: # freebsd-update install At this point, users of systems being upgraded from FreeBSD 8.0-BETA2 or earlier will be prompted by freebsd-update to rebuild all third-party applications (e.g., ports installed from the ports tree) due to updates in system libraries. See: http://www.daemonology.net/blog/2009-07-11-freebsd-update-to-8.0-beta1.html for more details. After updating installed third-party applications (and again, only if freebsd-update printed a message indicating that this was necessary), run freebsd-update again so that it can delete the old (no longer used) system libraries: # freebsd-update install Finally, reboot into 8.0-RELEASE: # shutdown -r now Support ------- The FreeBSD Security Team currently plans to support FreeBSD 8.0 until November 30th, 2010.
