Text of the page (random words):
ed de raadt decided that the source code should be available for anyone to read at the time a small team of developers generally had access to a project s source code 96 chuck cranor 97 and de raadt concluded this practice was counter to the open source philosophy and inconvenient to potential contributors together cranor and de raadt set up the first public anonymous revision control system server de raadt s decision allowed users to take a more active role and established the project s commitment to open access 96 openbsd is notable for its continued use of cvs more precisely an unreleased openbsd managed fork named opencvs that was stated opencvs released soon in 2005 98 and in 2025 opencvs is to be released soon 99 though openbsd also has a webpage that describes opencvs 100 when most other projects that used it have migrated to other systems 101 openbsd does not include closed source binary drivers in the source tree nor does it include code requiring the signing of non disclosure agreements 102 since openbsd is based in canada no united states export restrictions on cryptography apply allowing the distribution to make full use of modern algorithms for encryption for example the swap space is divided into small sections and each section is encrypted with its own key ensuring that sensitive data does not leak into an insecure part of the system 18 openbsd randomizes various behaviors of applications making them less predictable and thus more difficult to attack for example pids are created and associated randomly to processes the bind system call uses random port numbers files are created with random inode numbers and ip datagrams have random identifiers 103 this approach also helps expose bugs in the kernel and in user space programs the openbsd policy on openness extends to hardware documentation in the slides for a december 2006 presentation de raadt explained that without it developers often make mistakes writing drivers and pointed out that the oh my god i got it to work rush is harder to achieve and some developers just give up 104 he went on to say that vendor supplied binary drivers are unacceptable for inclusion in openbsd that they have no trust of vendor binaries running in our kernel and that there is no way to fix them when they break 104 closed source and proprietary code edit in an interview with jeremy andrews after being asked what is it about binary firmware that you re willing to ship it versus binary blobs how can you trust the firmware binary to do what it should do and what if the firmware has a bug theo de raadt in part stated quite honestly i prefer chips which have no firmware and instead use correctly designed hardware logic which our driver must then drive and but in the end if we wish to support any such devices we must be practical we must accept the risk that there is a flaw in the firmware 87 openbsd s github mirror has licenses for firmware that forbids use in non ti devices 105 forbid reverse engineering decompilation or disassembly of some software 106 107 108 firmware that is only allowed to be redistributed in object code only 109 has no copyright notice in the original file 110 or where openbsd developers believe the original license on the source did specifically allow re distribution 111 according to the gnu project openbsd includes small blobs of proprietary object code as device firmware or loaded by freely licensed drivers 112 licensing edit see also comparison of free and open source software licenses and free software license openbsd maintains a strict license policy 3 preferring the isc license and other variants of the bsd license the project attempts to maintain the spirit of the original berkeley unix copyrights which permitted a relatively un encumbered unix source distribution 3 the widely used apache license and gnu general public license are considered overly restrictive 113 in june 2001 triggered by concerns over darren reed s modification of ipfilter s license wording a systematic license audit of the openbsd ports and source trees was undertaken 114 code in more than a hundred files throughout the system was found to be unlicensed ambiguously licensed or in use against the terms of the license to ensure that all licenses were properly adhered to an attempt was made to contact all the relevant copyright holders some pieces of code were removed many were replaced and others such as the multicast routing tools mrinfo and map mbone were relicensed so that openbsd could continue to use them 115 116 also removed during this audit was all software produced by daniel j bernstein at the time bernstein requested that all modified versions of his code be approved by him prior to redistribution a requirement to which openbsd developers were unwilling to devote time or effort 117 118 119 because of licensing concerns the openbsd team has reimplemented software from scratch or adopted suitable existing software for example openbsd developers created the pf packet filter after unacceptable restrictions were imposed on ipfilter pf first appeared in openbsd 3 0 120 and is now available in many other operating systems 121 openbsd developers have also replaced gpl licensed tools such as cvs and pkg config with permissively licensed equivalents 122 123 funding edit although the operating system and its portable components are used in commercial products de raadt says that little of the funding for the project comes from the industry traditionally all our funding has come from user donations and users buying our cds our other products don t really make us much money obviously that has not been a lot of money 87 for a two year period in the early 2000s the project received funding from darpa which paid the salaries of 5 people to work completely full time bought about 30k in hardware and paid for 3 hackathons from the posse project 87 in 2006 the openbsd project experienced financial difficulties 124 the mozilla foundation 125 and godaddy 126 are among the organizations that helped openbsd to survive however de raadt expressed concern about the asymmetry of funding i think that contributions should have come first from the vendors secondly from the corporate users and thirdly from individual users but the response has been almost entirely the opposite with almost a 15 to 1 dollar ratio in favor of the little people thanks a lot little people 87 on 14 january 2014 bob beck issued a request for funding to cover electrical costs if sustainable funding was not found beck suggested the openbsd project would shut down 127 the project soon received a us 20 000 donation from mircea popescu the romanian creator of the mpex bitcoin stock exchange paid in bitcoins 128 the project raised us 150 000 129 in response to the appeal enabling it to pay its bills and securing its short term future 128 openbsd foundation edit openbsd foundation formation july 25 2007 19 years ago 2007 07 25 founder openbsd developers legal status nonprofit organization location canada website www openbsdfoundation org asn 22512 the openbsd foundation is a canadian federal non profit organization founded by the openbsd project as a single point of contact for persons and organizations requiring a legal entity to deal with when they wish to support openbsd 130 it was announced to the public by openbsd developer bob beck on 25 july 2007 it also serves as a legal safeguard over other projects which are affiliated with openbsd including openssh openbgpd openntpd opencvs opensmtpd and libressl 131 since 2014 several large contributions to the openbsd foundation have come from corporations such as microsoft 132 facebook and google as well as the core infrastructure initiative 133 in 2015 microsoft became the foundation s first gold level contributor 134 donating between 25 000 50 000 to support development of openssh which had been integrated into powershell in july and later into windows server in 2018 135 other contributors include google facebook and duckduckgo 136 during the 2016 and 2017 fundraising campaigns smartisan a chinese company was the leading financial contributor to the openbsd foundation 137 138 distribution edit openbsd is freely available in various ways the source can be retrieved by anonymous cvs 139 binary releases and development snapshots can be downloaded by ftp http and rsync 140 prepackaged cd rom sets through version 6 0 can be ordered online for a small fee complete with an assortment of stickers and a copy of the release s theme song these along with artwork and other bonuses have been one of the project s few sources of income funding hardware internet service and other expenses 141 beginning with version 6 1 cd rom sets are no longer released openbsd provides a package management system referred to as pkg tools for easy installation and management of programs which are not part of the base operating system 142 packages are binary files which are extracted managed and removed using the package tools on openbsd the source of packages is the ports system a collection of makefiles and other infrastructure required to create packages in openbsd the ports and base operating system are developed and released together for each version this means that the ports or packages released with for example 4 6 are not suitable for use with 4 5 and vice versa 142 songs and artwork edit 3d rendered animated openbsd mascot puffy initially openbsd used a haloed version of the bsd daemon mascot drawn by erick green who was asked by de raadt to create the logo for the 2 3 and 2 4 versions of openbsd green planned to create a full daemon including head and body but only the head was completed in time for openbsd 2 3 the body as well as pitchfork and tail was completed for openbsd 2 4 143 subsequent releases used variations such as a police daemon by ty semaka 144 but eventually settled on a pufferfish named puffy 145 since then puffy has appeared on openbsd promotional material and featured in release songs and artwork the promotional material of early openbsd releases did not have a cohesive theme or design but later the cd roms release songs posters and tee shirts for each release have been produced with a single style and theme sometimes contributed to by ty semaka of the plaid tongued devils 93 these have become a part of openbsd advocacy with each release expounding a moral or political point important to the project often through parody 146 themes have included puff the barbarian in openbsd 3 3 which included an 80s rock song and parody of conan the barbarian alluding to open documentation 93 the wizard of os in openbsd 3 7 related to the project s work on wireless drivers and hackers of the lost
