History

NetBSD was originally derived from the 4.3BSD-Reno release of the Berkeley Software Distribution from the Computer Systems Research Group of the University of California, Berkeley, via their Net/2 source code release and the 386BSD project. The NetBSD project began as a result of frustration within the 386BSD developer community with the pace and direction of the operating system's development.WEB, //www.netbsd.org/about/history.html, The History of the NetBSD Project, www.netbsd.org, The NetBSD Foundation, 29 November 2009, The four founders of the NetBSD project, Chris Demetriou, Theo de Raadt, Adam Glass, and Charles Hannum, felt that a more open development model would benefit the project: one centered on portable, clean, correct code. They aimed to produce a unified, multi-platform, production-quality, BSD-based operating system. The name "NetBSD" was suggested by de Raadt{{Citation needed|date=September 2016}}, based on the importance and growth of networks such as the Internet at that time, and the distributed, collaborative nature of its development.The NetBSD source code repository was established on 21 March 1993 and the first official release, NetBSD 0.8, was made in April, 1993.NEWSGROUP,weblink So you say you want an interim release of 386bsd?, Chris G. Demetriou, 19 April 1993, 1qvpc9$1e8@agate.berkeley.edu, comp.os.386bsd.announce, 12 May 2010, This was derived from 386BSD 0.1 plus the version 0.2.2 unofficial patchkit, with several programs from the Net/2 release missing from 386BSD re-integrated, and various other improvements.WEB,weblink Information about NetBSD 0.8, The first multi-platform release, NetBSD 1.0, was made in October 1994, and being updated with 4.4BSD-Lite sources, it was free of all legally encumbered 4.3BSD Net/2 code.WEB,weblink Information about NetBSD 1.0, Also in 1994, for disputed reasons, one of the founders, Theo de Raadt, was removed from the project. He later founded a new project, OpenBSD, from a forked version of NetBSD 1.0 near the end of 1995.WEB,weblink Theo, de Raadt, Theo de Raadt, Archive of the mail conversation leading to Theo de Raadt's departure, 29 March 2009, 15 January 2010, In 1998, NetBSD 1.3 introduced the pkgsrc packages collection.WEB, //www.netbsd.org/docs/pkgsrc/introduction.html#supported-platforms, Platforms supported by pkgsrc, www.netbsd.org, The NetBSD Foundation, 10 January 2010, Until 2004, NetBSD 1.x releases were made at roughly annual intervals, with minor "patch" releases in between. From release 2.0 onwards, NetBSD uses semantic versioning, and each major NetBSD release corresponds to an incremented major version number, i.e. the major releases following 2.0 are 3.0, 4.0 and so on. The previous minor releases are now divided into two categories: x.y "stable" maintenance releases and x.y.z releases containing only security and critical fixes.WEB, //www.netbsd.org/releases/release-map.html, NetBSD release glossary and graphs, 13 January 2010, The NetBSD Project, 15 January 2010,

Features

Portability

As the project's motto ("Of course it runs NetBSD" ) suggests, NetBSD has been ported to a large number of 32- and 64-bit architectures. These range from VAX minicomputers to Pocket PC PDAs. As of 2009, NetBSD supports 57 hardware platforms (across 15 different instruction sets). The kernel and userland for these platforms are all built from a central unified source-code tree managed by CVS. Currently, unlike other kernels such as μClinux, the NetBSD kernel requires the presence of an MMU in any given target architecture.NetBSD's portability is aided by the use of hardware abstraction layer interfaces for low-level hardware access such as bus input/output or DMA. Using this portability layer, device drivers can be split into "machine-independent" and "machine-dependent" components. This makes a single driver easily usable on several platforms by hiding hardware access details, and reduces the work to port it to a new system.WEB,weblink Portability and supported hardware platforms, www.netbsd.org, The NetBSD Foundation, 29 November 2009, This permits a particular device driver for a PCI card to work without modifications, whether it is in a PCI slot on an IA-32, Alpha, PowerPC, SPARC, or other architecture with a PCI bus. Also, a single driver for a specific device can operate via several different buses, like ISA, PCI, or PC Card.In comparison, Linux device driver code often must be reworked for each new architecture. As a consequence, in porting efforts by NetBSD and Linux developers, NetBSD has taken much less time to port to new hardware.{{Better source|reason=Recent and still available source|date=May 2014}}This platform independence aids the development of embedded systems, particularly since NetBSD 1.6, when the entire toolchain of compilers, assemblers, linkers, and other tools fully support cross-compiling.In 2005, as a demonstration of NetBSD's portability and suitability for embedded applications, Technologic Systems, a vendor of embedded systems hardware, designed and demonstrated a NetBSD-powered kitchen toaster.PRESS RELEASE,weblink Technologic Systems Designs NetBSD Controlled Toaster, August 2005, 11 June 2007, Commercial ports to embedded platforms, including the AMD Geode LX800, Freescale PowerQUICC processors, Marvell Orion, AMCC 405 family of PowerPC processors, Intel XScale IOP and IXP series, were available from and supported by Wasabi Systems.

Portable build framework

The NetBSD cross-compiling framework (also known as "build.sh"WEB, urlwww.netbsd.org/docs/guide/en/chap-build.html, Chapter 31. Crosscompiling NetBSD with build.sh, The NetBSD Guide, The NetBSD Foundation, 10 January 2010, 15 January 2010, ) lets a developer build a complete NetBSD system for an architecture from a more powerful system of different architecture (cross-compiling), including on a different operating system (the framework supports most POSIX-compliant systems). Several embedded systems using NetBSD have required no additional software development other than toolchain and target rehost.WEB, http:wasabisystems.com/pdfs/Linux_or_BSD.pdf, BSD or Linux: Which Unix is better for embedded applications?, 2003, Wasabi Systems Inc., PDF, 11 June 2007, 30 December 2006,weblink" title="web.archive.org/web/20061230075423weblink">weblink

The pkgsrc packages collection

NetBSD features pkgsrc (short for "package source"), a framework for building and managing third-party application software packages. The pkgsrc collection consists of more than 18,000 packages as of {{As of|2018|alt=April 2018}}.WEB,weblink The pkgsrc-2018Q1 Release, Building and installing packages such as KDE, GNOME, the Apache HTTP Server or Perl is performed through the use of a system of makefiles. This can automatically fetch the source code, unpack, patch, configure, build and install the package such that it can be removed again later. An alternative to compiling from source is to use a precompiled binary package. In either case, any prerequisites/dependencies will be installed automatically by the package system, without need for manual intervention.pkgsrc supports not only NetBSD, but also several other BSD variants like FreeBSD and Darwin/Mac OS X, and other Unix-like operating systems such as Linux, Solaris, IRIX, and others, as well as Interix. pkgsrc was previously adopted as the official package management system for DragonFly BSD.MAILING LIST,weblink PKGSRC will be officially supported as of the next release, Matthew, Dillon, DragonFly users List, 31 August 2005, 15 January 2010,

Symmetric multiprocessing

NetBSD has supported SMP since the NetBSD 2.0 release in 2004,WEB, urlwww.netbsd.org/changes/2004.html#netbsd-2.0, NetBSD 2.0 release notes, which was initially implemented using the giant lock approach. During the development cycle of the NetBSD 5 release, major work was done to improve SMP support; most of the kernel subsystems were modified to be MP safe and use the fine-grained locking approach. New synchronization primitives were implemented and scheduler activations was replaced with a (Thread (computer science)#1:1|1:1 threading model) in February 2007.WEB, www.netbsd.org/changes/changes-5.0.html, Significant changes from NetBSD 4.0 to 5.0, 23 December 2009, 15 January 2010, A scalable M2 thread scheduler was implemented, though the old 4.4BSD scheduler still remains the default but was modified to scale with SMP. Threaded software interrupts were implemented to improve synchronization. The virtual memory system, memory allocator and trap handling were made MP safe. The file system framework, including the VFS and major file systems were modified to be MP safe. Since April, 2008 the only subsystems running with a giant lock are the network protocols and most device drivers.

Security

NetBSD provides various features in the security area.WEB,weblink NetBSD security(8) manual page, The Kernel Authorization frameworkWEB,weblink kauth(9), NetBSD Manual Pages, 10 August 2009, 15 January 2010, (or Kauth) is a subsystem managing all authorization requests inside the kernel, and used as system-wide security policy. It allows external modules to plug-in the authorization process. NetBSD also incorporates exploit mitigation features, ASLR WEB,weblink NetBSD paxctl(8) manual page, , KASLR, restricted mprotect() and Segvguard from the PaX project, and GCC Stack Smashing Protection (SSP, or also known as ProPolice, enabled by default since NetBSD 6.0) compiler extensions. Verified Executables (or Veriexec) is an in-kernel file integrity subsystem in NetBSD. It allows the user to set digital fingerprints (hashes) of files, and take a number of different actions if files do not match their fingerprints. For example, one can allow Perl to run only scripts that match their fingerprints.WEB, urlwww.netbsd.org/docs/guide/en/chap-veriexec.html, Chapter 19. NetBSD Veriexec subsystem, The cryptographic device driver (CGD) allows using disks or partitions (including CDs and DVDs) for encrypted storage.WEB, www.netbsd.org/docs/guide/en/chap-cgd.html, Chapter 14. The cryptographic device driver (CGD),

Virtualization

The Xen virtual-machine monitor has been supported in NetBSD since release 3.0. The use of Xen requires a special pre-kernel boot environment that loads a Xen-specialized kernel as the "host OS" (Dom0). Any number of "guest OSes" (DomU) virtualized computers, with or without specific Xen/DomU support, can be run in parallel with the appropriate hardware resources.The need for a third-party boot manager, such as GRUB, was eliminated with NetBSD 5's Xen-compatible boot manager.WEB,weblink boot(8), NetBSD Manual Pages, 4 September 2009, 15 January 2010, NetBSD 6 as a Dom0 has been benchmarked comparably to Linux, with better performance than Linux in some tests.WEB,weblink (Free and Net) BSD Xen Roadmap, Cherry G., Matthew, Roger Pau, Monné, August 2012, 29 December 2012, User-space virtualization such as VirtualBox and QEMU are also supported on NetBSD.NetBSD 5.0 introduced the rump kernel, an architecture to run drivers in user-space by emulating kernel-space calls. This anykernel architecture allows adding support of NetBSD drivers to other kernel architectures, ranging from exokernels to monolithic kernels.WEB, //www.netbsd.org/docs/rump/, The Anykernel and Rump Kernels,

Storage

NetBSD includes many enterprise features like iSCSI, a journaling filesystem, logical volume management and the ZFS filesystem.The WAPBL journaling filesystem, an extension of the BSD FFS filesystem, was contributed by Wasabi Systems in 2008.MAILING LIST,weblink Patches for journalling support, Simon, Burge, 2 March 2008, tech-kern@NetBSD.org, 15 January 2010, The NetBSD Logical Volume Manager is based on a BSD reimplementation of a device-mapper driver and a port of the Linux Logical Volume Manager tools. It was mostly written during the Google Summer of Code 2008.MAILING LIST,weblink HEADS UP NetBSD lvm support, Adam, Hamsik, 29 August 2008, tech-kern@NetBSD.org, 15 January 2010, The ZFS filesystem developed by Sun Microsystems was imported into the NetBSD base system in 2009. Currently,{{When?|date=August 2018}} the NetBSD ZFS port is based on ZFS version 22.The CHFS Flash memory filesystem was imported into NetBSD in November 2011. CHFS is a file system developed at the Department of Software Engineering, University of Szeged, Hungary, and is the first open source Flash-specific file system written for NetBSD.

Compatibility with other operating systems

At the source code level, NetBSD is very nearly entirely compliant with POSIX.1 (IEEE 1003.1-1990) standard and mostly compliant with POSIX.2 (IEEE 1003.2-1992).NetBSD provides system call-level binary compatibility on the appropriate processor architectures with its previous releases, but also with several other UNIX-derived and UNIX-like operating systems, including illumos/Solaris, Linux, other BSD variants like FreeBSD and SunOS 4. This allows NetBSD users to run many applications that are only distributed in binary form for other operating systems, usually with no significant loss of performance.WEB, //www.netbsd.org/docs/compat.html, NetBSD Binary Emulation, 13 January 2010, 15 January 2010, A variety of "foreign" disk filesystem formats are also supported in NetBSD, including FAT, NTFS, Linux ext2fs, OS X UFS, RISC OS FileCore/ADFS, AmigaOS Fast File System, IRIX EFS and many more through FUSE.

Kernel scripting

Kernel-space scripting with the Lua programming language is a relatively new feature in NetBSD; it is available as of NetBSD 7.0.WEB,weblink Scriptable Operating Systems with Lua, The Lua language (i.e., its interpreter and standard libraries) was initially ported to the NetBSD kernel during Google Summer of Code 2010 and has undergone several improvements since then. There are two main differences between user and kernel space Lua: kernel Lua does not support floating-point numbers; as such, only Lua integers are available. It also does not have full support to user space libraries that rely on the operating system (e.g., io and os).

Licensing

All of the NetBSD kernel and most of the core userland source code is released under the terms of the BSD License (two, three, and four-clause variants). This essentially allows everyone to use, modify, redistribute or sell it as they wish, as long as they do not remove the copyright notice and license text (the four-clause variants also include terms relating to publicity material). Thus, the development of products based on NetBSD is possible without having to make modifications to the source code public. In contrast, the GPL, which does not apply to NetBSD, stipulates that changes to source code of a product must be released to the product recipient when products derived from those changes are released.On 20 June 2008, the NetBSD Foundation announced a transition to the two clause BSD license, citing concerns with UCB support of clause 3 and industry applicability of clause 4.PRESS RELEASE, //www.netbsd.org/about/redistribution.html#why2clause, NetBSD Licensing and Redistribution, June 2008, 20 June 2008, NetBSD also includes the GNU development tools and other packages, which are covered by the GPL and other open source licenses. As with other BSD projects, NetBSD separates those in its base source tree to make it easier to remove code that is under more restrictive licenses.WEB, Distro description,weblink Free Penguin, 7 June 2014, Licensing Section, NetBSD separates those in its base source tree, in order to make removal of code under more restrictive licenses easier., As for packages, the installed software licenses may be controlled by modifying the list of allowed licenses in the pkgsrc configuration file (mk.conf).
