Announcing NetBSD 6.0


The NetBSD Project is pleased to announce NetBSD 6.0, the fourteenth major release of the NetBSD operating system. Changes from the previous release include scalability improvements on multi-core systems, many new and updated device drivers, Xen and MIPS port improvements, and brand new features such as a new packet filter.

Some NetBSD 6.0 highlights are: support for thread-local storage (TLS), Logical Volume Manager (LVM) functionality, rewritten disk quota subsystem, new subsystems to handle flash devices and NAND controllers, an experimental CHFS file system designed for flash devices, support for Multiprotocol Label Switching (MPLS) protocol, and more. This release also introduces NetBSD Packet Filter (NPF) - a new packet filter, designed with multi-core systems in mind, which can do TCP/IP traffic filtering, stateful inspection, and network address translation (NAT).

In addition to many other features, NetBSD 6.0 includes significant developments in various ports. Some highlights:

  • SMP support for Xen domU kernels, initial suspend/resume support for Xen domU, PCI pass-through support for Xen3, and addition of the balloon driver.
  • Major rework of MIPS port adding support for SMP and 64-bit (O32, N32, N64 ABIs are supported) processors, DSP v2 ASE extension, various NetLogic/RMI processor models, Loongson family processors, and new SoC boards.
  • Improved SMP on PowerPC port and added support for Book E Freescale MPC85xx (e500 core) processors.
  • ARM has gained support for Cortex-A8 processors, various new SoCs, and initial support for Raspberry Pi. Full support for Raspberry Pi and major ARM improvements to come in a future NetBSD release.
  • time_t is now a 64-bit quantity on all NetBSD ports. This means that the NetBSD world no longer ends in 2037.

Please read below for a full list of changes in NetBSD 6.0.

The generous donations of companies and individuals to the NetBSD Foundation in previous years has enabled TNF to sponsor some exciting developments in NetBSD 6.0, including the Xen DOMU multiprocessor support. See below for information about how you or your company can donate to help sponsor future projects!

NetBSD 6.0 is dedicated to the memory of Allen Briggs, who passed away in March of 2012.

Allen's technical contributions to NetBSD were significant, and many. He was a NetBSD developer from the very beginning of the project, and was the main driving force behind the initial import of some of our hardware ports. He also served on NetBSD's core team from 2003 until 2006. More than that, however, he was a mentor to many on the project, and always willing to help when he could. Even for those he didn't mentor, his civilized example was often a guiding influence. He worked with many of us on the project, and in a field where prickly personalities are common, he was always pleasant and kind regardless of your status or technical expertise. He will be sorely missed.

6.0 Fund Drive

Your donation to the NetBSD Foundation allows the project to make major improvements to the code base. With the release of NetBSD 6.0, the 6.0 Fund Drive targets raising 60,000 USD by the end of 2012. We would like to continue funded development in various areas, including:

  • Improving network stack concurrency and performance.
  • Development of modern file systems and improvement of existing ones.
  • Features which are useful in embedded environments, such as high resolution timers and execute in place (XIP) support.
  • Automatic testing and quality assurance.
We have recently made some changes to the way we accept and honor your donations. For more information about donating, visit The NetBSD Foundation is a 501(c)(3) organization in the US, and donations may be tax deductible.

Besides this list, there have also been innumerable bug fixes and miscellaneous enhancements.

Components removed from NetBSD

In this release of NetBSD, the following software components have been removed from the system. Some were not useful anymore, or their utility did not justify the maintenance overhead. Others were not working properly and there was a lack of interest in fixing them.

  • Support for Xen 2 has been dropped. Xen 3.1 or later is now required to run NetBSD.
  • Support for LKMs (Loadable Kernel Modules) was dropped; use the new module(7) framework.
  • softdep support is no longer available in FFS; use wapbl(4) logging instead.
  • The playstation2 port was removed.
  • tn3270 was removed from base; it is available in pkgsrc.
  • Support for Darwin, Mach, IRIX and PECOFF emulation was retired.

The NetBSD Foundation would like to thank all those who have contributed code, hardware, documentation, funds, colocation for our servers, web pages and other documentation, release engineering, and other resources over the years. More information on the people who make NetBSD happen is available at:

We would like to especially thank the University of California at Berkeley and the GNU Project for particularly large subsets of code that we use. We would also like to thank the Internet Systems Consortium Inc. and the Network Security Lab at Columbia University's Computer Science Department for current colocation services.

About NetBSD

NetBSD is a free, fast, secure, and highly portable Unix-like Open Source operating system. It is available for a wide range of platforms, from large-scale servers and powerful desktop systems to handheld and embedded devices. Its clean design and advanced features make it excellent for use in both production and research environments, and the source code is freely available under a business-friendly license. NetBSD is developed and supported by a large and vibrant international community. Many applications are readily available through pkgsrc, the NetBSD Packages Collection.

About the NetBSD Foundation

The NetBSD Foundation was chartered in 1995, with the task of overseeing core NetBSD project services, promoting the project within industry and the open source community, and holding intellectual property rights on much of the NetBSD code base. Day-to-day operations of the project are handled by volunteers.

As a non-profit organization with no commercial backing, the NetBSD Foundation depends on donations from its users, and we would like to ask you to consider making a donation to the NetBSD Foundation in support of continuing production of our fine operating system. Your generous donation would be particularly welcome to help with ongoing upgrades and maintenance, as well as with operating expenses for the NetBSD Foundation.

Donations can be done via PayPal to , or via Google Checkout and are fully tax-deductible in the US. See for more information, or contact directly.
