1The majority of code in VirtualBox Open Source Edition (OSE) is
2copyrighted by innotek GmbH. This code is combined with third-party code
3that was originally released under the Apache License 2.0, the OpenSSL
4license, the Mozilla Public License (MPL) and the Slirp license, all of
5which the Free Software Foundation considers to be incompatible with the
6GPL, as well as the X11, zlib, liblzf and LGPL licenses. As a special
7exception to the terms and conditions of the GPL listed below, innotek
8gives you explicit permission to combine its GPL code contained in
9VirtualBox OSE with third-party code under the aforementioned licenses.
10You may copy and distribute such a combination provided that you adhere
11to the terms and conditions of all of the GPL and the licenses of the
12third-party code; in particular, you must include the source code of
13the entire combination insofar as the GPL requires distribution of
14source code.
15
16Note that whoever creates or distributes a derived work based on
17VirtualBox OSE is not obligated to grant this special exception for such
18a version. The GPL allows for releasing a modified version without the
19above exception; innotek also allows you to release a modified version
20which carries forward this exception.

25 GNU GENERAL PUBLIC LICENSE
26 Version 2, June 1991
27
28 Copyright (C) 1989, 1991 Free Software Foundation, Inc.
29 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA
30 Everyone is permitted to copy and distribute verbatim copies
31 of this license document, but changing it is not allowed.
32
33 Preamble
34
35 The licenses for most software are designed to take away your
36freedom to share and change it. By contrast, the GNU General Public
37License is intended to guarantee your freedom to share and change free
38software--to make sure the software is free for all its users. This
39General Public License applies to most of the Free Software
40Foundation's software and to any other program whose authors commit to
41using it. (Some other Free Software Foundation software is covered by
42the GNU Library General Public License instead.) You can apply it to
43your programs, too.
44
45 When we speak of free software, we are referring to freedom, not
46price. Our General Public Licenses are designed to make sure that you
47have the freedom to distribute copies of free software (and charge for
48this service if you wish), that you receive source code or can get it
49if you want it, that you can change the software or use pieces of it
50in new free programs; and that you know you can do these things.
51
52 To protect your rights, we need to make restrictions that forbid
53anyone to deny you these rights or to ask you to surrender the rights.
54These restrictions translate to certain responsibilities for you if you
55distribute copies of the software, or if you modify it.
56
57 For example, if you distribute copies of such a program, whether
58gratis or for a fee, you must give the recipients all the rights that
59you have. You must make sure that they, too, receive or can get the
60source code. And you must show them these terms so they know their
61rights.
62
63 We protect your rights with two steps: (1) copyright the software, and
64(2) offer you this license which gives you legal permission to copy,
65distribute and/or modify the software.
66
67 Also, for each author's protection and ours, we want to make certain
68that everyone understands that there is no warranty for this free
69software. If the software is modified by someone else and passed on, we
70want its recipients to know that what they have is not the original, so
71that any problems introduced by others will not reflect on the original
72authors' reputations.
73
74 Finally, any free program is threatened constantly by software
75patents. We wish to avoid the danger that redistributors of a free
76program will individually obtain patent licenses, in effect making the
77program proprietary. To prevent this, we have made it clear that any
78patent must be licensed for everyone's free use or not licensed at all.
79
80 The precise terms and conditions for copying, distribution and
81modification follow.
82
83
84 GNU GENERAL PUBLIC LICENSE
85 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
86
87 0. This License applies to any program or other work which contains
88a notice placed by the copyright holder saying it may be distributed
89under the terms of this General Public License. The "Program", below,
90refers to any such program or work, and a "work based on the Program"
91means either the Program or any derivative work under copyright law:
92that is to say, a work containing the Program or a portion of it,
93either verbatim or with modifications and/or translated into another
94language. (Hereinafter, translation is included without limitation in
95the term "modification".) Each licensee is addressed as "you".
96
97Activities other than copying, distribution and modification are not
98covered by this License; they are outside its scope. The act of
99running the Program is not restricted, and the output from the Program
100is covered only if its contents constitute a work based on the
101Program (independent of having been made by running the Program).
102Whether that is true depends on what the Program does.
103
104 1. You may copy and distribute verbatim copies of the Program's
105source code as you receive it, in any medium, provided that you
106conspicuously and appropriately publish on each copy an appropriate
107copyright notice and disclaimer of warranty; keep intact all the
108notices that refer to this License and to the absence of any warranty;
109and give any other recipients of the Program a copy of this License
110along with the Program.
111
112You may charge a fee for the physical act of transferring a copy, and
113you may at your option offer warranty protection in exchange for a fee.
114
115 2. You may modify your copy or copies of the Program or any portion
116of it, thus forming a work based on the Program, and copy and
117distribute such modifications or work under the terms of Section 1
118above, provided that you also meet all of these conditions:
119
120 a) You must cause the modified files to carry prominent notices
121 stating that you changed the files and the date of any change.
122
123 b) You must cause any work that you distribute or publish, that in
124 whole or in part contains or is derived from the Program or any
125 part thereof, to be licensed as a whole at no charge to all third
126 parties under the terms of this License.
127
128 c) If the modified program normally reads commands interactively
129 when run, you must cause it, when started running for such
130 interactive use in the most ordinary way, to print or display an
131 announcement including an appropriate copyright notice and a
132 notice that there is no warranty (or else, saying that you provide
133 a warranty) and that users may redistribute the program under
134 these conditions, and telling the user how to view a copy of this
135 License. (Exception: if the Program itself is interactive but
136 does not normally print such an announcement, your work based on
137 the Program is not required to print an announcement.)
138
139
140These requirements apply to the modified work as a whole. If
141identifiable sections of that work are not derived from the Program,
142and can be reasonably considered independent and separate works in
143themselves, then this License, and its terms, do not apply to those
144sections when you distribute them as separate works. But when you
145distribute the same sections as part of a whole which is a work based
146on the Program, the distribution of the whole must be on the terms of
147this License, whose permissions for other licensees extend to the
148entire whole, and thus to each and every part regardless of who wrote it.
149
150Thus, it is not the intent of this section to claim rights or contest
151your rights to work written entirely by you; rather, the intent is to
152exercise the right to control the distribution of derivative or
153collective works based on the Program.
154
155In addition, mere aggregation of another work not based on the Program
156with the Program (or with a work based on the Program) on a volume of
157a storage or distribution medium does not bring the other work under
158the scope of this License.
159
160 3. You may copy and distribute the Program (or a work based on it,
161under Section 2) in object code or executable form under the terms of
162Sections 1 and 2 above provided that you also do one of the following:
163
164 a) Accompany it with the complete corresponding machine-readable
165 source code, which must be distributed under the terms of Sections
166 1 and 2 above on a medium customarily used for software interchange; or,
167
168 b) Accompany it with a written offer, valid for at least three
169 years, to give any third party, for a charge no more than your
170 cost of physically performing source distribution, a complete
171 machine-readable copy of the corresponding source code, to be
172 distributed under the terms of Sections 1 and 2 above on a medium
173 customarily used for software interchange; or,
174
175 c) Accompany it with the information you received as to the offer
176 to distribute corresponding source code. (This alternative is
177 allowed only for noncommercial distribution and only if you
178 received the program in object code or executable form with such
179 an offer, in accord with Subsection b above.)
180
181The source code for a work means the preferred form of the work for
182making modifications to it. For an executable work, complete source
183code means all the source code for all modules it contains, plus any
184associated interface definition files, plus the scripts used to
185control compilation and installation of the executable. However, as a
186special exception, the source code distributed need not include
187anything that is normally distributed (in either source or binary
188form) with the major components (compiler, kernel, and so on) of the
189operating system on which the executable runs, unless that component
190itself accompanies the executable.
191
192If distribution of executable or object code is made by offering
193access to copy from a designated place, then offering equivalent
194access to copy the source code from the same place counts as
195distribution of the source code, even though third parties are not
196compelled to copy the source along with the object code.
197
198
199 4. You may not copy, modify, sublicense, or distribute the Program
200except as expressly provided under this License. Any attempt
201otherwise to copy, modify, sublicense or distribute the Program is
202void, and will automatically terminate your rights under this License.
203However, parties who have received copies, or rights, from you under
204this License will not have their licenses terminated so long as such
205parties remain in full compliance.
206
207 5. You are not required to accept this License, since you have not
208signed it. However, nothing else grants you permission to modify or
209distribute the Program or its derivative works. These actions are
210prohibited by law if you do not accept this License. Therefore, by
211modifying or distributing the Program (or any work based on the
212Program), you indicate your acceptance of this License to do so, and
213all its terms and conditions for copying, distributing or modifying
214the Program or works based on it.
215
216 6. Each time you redistribute the Program (or any work based on the
217Program), the recipient automatically receives a license from the
218original licensor to copy, distribute or modify the Program subject to
219these terms and conditions. You may not impose any further
220restrictions on the recipients' exercise of the rights granted herein.
221You are not responsible for enforcing compliance by third parties to
222this License.
223
224 7. If, as a consequence of a court judgment or allegation of patent
225infringement or for any other reason (not limited to patent issues),
226conditions are imposed on you (whether by court order, agreement or
227otherwise) that contradict the conditions of this License, they do not
228excuse you from the conditions of this License. If you cannot
229distribute so as to satisfy simultaneously your obligations under this
230License and any other pertinent obligations, then as a consequence you
231may not distribute the Program at all. For example, if a patent
232license would not permit royalty-free redistribution of the Program by
233all those who receive copies directly or indirectly through you, then
234the only way you could satisfy both it and this License would be to
235refrain entirely from distribution of the Program.
236
237If any portion of this section is held invalid or unenforceable under
238any particular circumstance, the balance of the section is intended to
239apply and the section as a whole is intended to apply in other
240circumstances.
241
242It is not the purpose of this section to induce you to infringe any
243patents or other property right claims or to contest validity of any
244such claims; this section has the sole purpose of protecting the
245integrity of the free software distribution system, which is
246implemented by public license practices. Many people have made
247generous contributions to the wide range of software distributed
248through that system in reliance on consistent application of that
249system; it is up to the author/donor to decide if he or she is willing
250to distribute software through any other system and a licensee cannot
251impose that choice.
252
253This section is intended to make thoroughly clear what is believed to
254be a consequence of the rest of this License.
255
256
257 8. If the distribution and/or use of the Program is restricted in
258certain countries either by patents or by copyrighted interfaces, the
259original copyright holder who places the Program under this License
260may add an explicit geographical distribution limitation excluding
261those countries, so that distribution is permitted only in or among
262countries not thus excluded. In such case, this License incorporates
263the limitation as if written in the body of this License.
264
265 9. The Free Software Foundation may publish revised and/or new versions
266of the General Public License from time to time. Such new versions will
267be similar in spirit to the present version, but may differ in detail to
268address new problems or concerns.
269
270Each version is given a distinguishing version number. If the Program
271specifies a version number of this License which applies to it and "any
272later version", you have the option of following the terms and conditions
273either of that version or of any later version published by the Free
274Software Foundation. If the Program does not specify a version number of
275this License, you may choose any version ever published by the Free Software
276Foundation.
277
278 10. If you wish to incorporate parts of the Program into other free
279programs whose distribution conditions are different, write to the author
280to ask for permission. For software which is copyrighted by the Free
281Software Foundation, write to the Free Software Foundation; we sometimes
282make exceptions for this. Our decision will be guided by the two goals
283of preserving the free status of all derivatives of our free software and
284of promoting the sharing and reuse of software generally.
285
286 NO WARRANTY
287
288 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
289FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
290OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
291PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
292OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
293MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
294TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
295PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
296REPAIR OR CORRECTION.
297
298 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
299WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
300REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
301INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
302OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
303TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
304YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
305PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
306POSSIBILITY OF SUCH DAMAGES.
307
308 END OF TERMS AND CONDITIONS
309
310
311 How to Apply These Terms to Your New Programs
312
313 If you develop a new program, and you want it to be of the greatest
314possible use to the public, the best way to achieve this is to make it
315free software which everyone can redistribute and change under these terms.
316
317 To do so, attach the following notices to the program. It is safest
318to attach them to the start of each source file to most effectively
319convey the exclusion of warranty; and each file should have at least
320the "copyright" line and a pointer to where the full notice is found.
321
322 <one line to give the program's name and a brief idea of what it does.>
323 Copyright (C) <year> <name of author>
324
325 This program is free software; you can redistribute it and/or modify
326 it under the terms of the GNU General Public License as published by
327 the Free Software Foundation; either version 2 of the License, or
328 (at your option) any later version.
329
330 This program is distributed in the hope that it will be useful,
331 but WITHOUT ANY WARRANTY; without even the implied warranty of
332 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
333 GNU General Public License for more details.
334
335 You should have received a copy of the GNU General Public License
336 along with this program; if not, write to the Free Software
337 Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA
338
339
340Also add information on how to contact you by electronic and paper mail.
341
342If the program is interactive, make it output a short notice like this
343when it starts in an interactive mode:
344
345 Gnomovision version 69, Copyright (C) year name of author
346 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
347 This is free software, and you are welcome to redistribute it
348 under certain conditions; type `show c' for details.
349
350The hypothetical commands `show w' and `show c' should show the appropriate
351parts of the General Public License. Of course, the commands you use may
352be called something other than `show w' and `show c'; they could even be
353mouse-clicks or menu items--whatever suits your program.
354
355You should also get your employer (if you work as a programmer) or your
356school, if any, to sign a "copyright disclaimer" for the program, if
357necessary. Here is a sample; alter the names:
358
359 Yoyodyne, Inc., hereby disclaims all copyright interest in the program
360 `Gnomovision' (which makes passes at compilers) written by James Hacker.
361
362 <signature of Ty Coon>, 1 April 1989
363 Ty Coon, President of Vice
364
365This General Public License does not permit incorporating your program into
366proprietary programs. If your program is a subroutine library, you may
367consider it more useful to permit linking proprietary applications with the
368library. If this is what you want to do, use the GNU Lesser General
369Public License instead of this License.
