DragonFly Release 2.2.1 - 26 April 2009

The DragonFly 2.2 release is here! The HAMMER filesystem is considered production-ready in this release; It was first released in July 2008. The 2.2 release represents major stability improvements across the board, new drivers, much better pkgsrc support and integration, and a brand new release infrastructure with multiple target options.

Three release options are now available: Our bare-bones CD ISO, a DVD ISO which includes a fully operational X environment, and a bare-bones bootable USB disk-key image (less than 512M).

Availability

The release ISO images should be available on most of the mirrors. If the ISO is not available on a certain mirror, please try another one or download it from the DragonFly FTP server.

pkgsrc packages

We offer over 7300 pre-built pkgsrc packages for this release. The pkg_radd(1) utility may be used to download pre-built binary packages. By default this script will query the main package site for a random redirect to one of our mirrors. The path can be overridden by setting BINPKG_SITES in /etc/settings.conf.

To get a list of all packages, let pkg_search(1) download the summary file for that release:

DragonFly 2.2.0 Release Notes

Release Improvements

A new DVD ISO release image is now available, in addition to the CD release.
The new DVD release has a full X environment ready-to-go and many packages pre-installed.
A full pkgsrc tar is now available on the CD/DVD in /usr.
Full sources tar now available on the DVD (kernel sources only on the CD), in /usr.
The nrelease build now trivializes package selection for people creating customized releases.
The installer is now able to create a HAMMER filesystem setup.

Kernel changes

First step towards AMD64 support (done by Jordan Gordeev during the Google Summer of Code 2008).
The system control intr_mpsafe is enabled by default.
Move /kernel to /boot/kernel and /modules to /boot/modules.
Add RFC3542 support (done by Dashu Huang during the Google Summer of Code 2008).
Add HW checksum support to the loopback interface, which doubles performance.
acpi_cpu(4) update. It's now possible to use higher (lower power usage) C states than C1 in modern (multicore) CPUs.
First steps to use network threads without the Big Giant Lock (this feature is considered experimental).
Fixed CVE-2008-2476 IPv6 security issue with modified patches from NetBSD.
bridge_input works now in parallel.
Fix bugs in dealing with low-memory situations when the system has run out of swap or has no swap.
Major rewrite of usched_bsd4 and related support logic, plus additional improvements to the LWKT scheduler.
Major revamping of the pageout and low-memory handling code.
suser_* replaced with priv_* implementation from FreeBSD.

HAMMER changes

HAMMER is now considered production-capable. Many bug fixes and other improvements have been made.
It is now possible to boot from a HAMMER-only disk. No need for a single UFS partition for /boot. However, for production systems we still recommend a small UFS /boot followed by swap followed by one large HAMMER partition.
Add HAMMER read support to the boot loader.
Now uses per-mount kmalloc pools for bulk data structures, particularly for inodes and records.

Hardware changes

Add ACPI support module Asus laptops (from FreeBSD).
Add acpi_video(4) - a driver for ACPI video extensions (from FreeBSD).

Update acpi_battery(4) related code to the latest one from FreeBSD HEAD.
Correctly handle Intel G33 chips and add support for G45 chips to the agp(4) driver (from FreeBSD).
Fixed CVE-2008-3831. Affects the Intel G33 series and newer only.
Sync ciss(4) with FreeBSD's RELENG_4 branch.
