By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Library General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES +PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED +OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF +MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, +REPAIR OR CORRECTION. + + 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR +REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING +OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED +TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY +YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER +PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE +POSSIBILITY OF SUCH DAMAGES. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + + Copyright (C) + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 2 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU General Public License for more details. + + You should have received a copy of the GNU General Public License + along with this program; if not, write to the Free Software + Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA + + +Also add information on how to contact you by electronic and paper mail. + +If the program is interactive, make it output a short notice like this +when it starts in an interactive mode: + + Gnomovision version 69, Copyright (C) year name of author + Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. + This is free software, and you are welcome to redistribute it + under certain conditions; type `show c' for details. + +The hypothetical commands `show w' and `show c' should show the appropriate +parts of the General Public License. Of course, the commands you use may +be called something other than `show w' and `show c'; they could even be +mouse-clicks or menu items--whatever suits your program. + +You should also get your employer (if you work as a programmer) or your +school, if any, to sign a "copyright disclaimer" for the program, if +necessary. Here is a sample; alter the names: + + Yoyodyne, Inc., hereby disclaims all copyright interest in the program + `Gnomovision' (which makes passes at compilers) written by James Hacker. + + , 1 April 1989 + Ty Coon, President of Vice + +This General Public License does not permit incorporating your program into +proprietary programs. If your program is a subroutine library, you may +consider it more useful to permit linking proprietary applications with the +library. If this is what you want to do, use the GNU Library General +Public License instead of this License. diff --git a/LICENSE b/LICENSE new file mode 100644 index 0000000..a159d8a --- /dev/null +++ b/LICENSE @@ -0,0 +1,176 @@ +OPEN SOFTWARE LICENSE 3.0 (OSL-3.0) + +This Open Software License (the "License") applies to any original work +of authorship (the "Original Work") whose owner (the "Licensor") has +placed the following licensing notice adjacent to the copyright notice +for the Original Work: + +Licensed under the Open Software License version 3.0 + +1) Grant of Copyright License.

Licensor grants You a worldwide, royalty-free, +non-exclusive, sublicensable license, under patent claims owned or +controlled by the Licensor that are embodied in the Original Work as +furnished by the Licensor, for the duration of the patents, to make, use, +sell, offer for sale, have made, and import the Original Work and +Derivative Works. + +3) Grant of Source Code License. The term "Source Code" means the preferred +form of the Original Work for making modifications to it and all available +documentation describing how to modify the Original Work. Licensor agrees +to provide a machine-readable copy of the Source Code of the Original Work +along with each copy of the Original Work that Licensor distributes. +Licensor reserves the right to satisfy this obligation by placing a +machine-readable copy of the Source Code in an information repository +reasonably calculated to permit inexpensive and convenient access by You +for as long as Licensor continues to distribute the Original Work. + +4) Exclusions From License Grant. Neither the names of Licensor, nor the +names of any contributors to the Original Work, nor any of their +trademarks or service marks, may be used to endorse or promote products +derived from this Original Work without express prior permission of the +Licensor. Except as expressly stated herein, nothing in this License +grants any license to Licensor's trademarks, copyrights, patents, trade +secrets or any other intellectual property. No patent license is granted +to make, use, sell, offer for sale, have made, or import embodiments of +any patent claims other than the licensed claims defined in Section 2. +No license is granted to the trademarks of Licensor even if such marks +are included in the Original Work. Nothing in this License shall be +interpreted to prohibit Licensor from licensing under terms different from +this License any Original Work that Licensor otherwise would have a right +to license. + +5) External Deployment. The term "External Deployment" means the use, +distribution, or communication of the Original Work or Derivative Works in +any way such that the Original Work or Derivative Works may be used by +anyone other than You, whether those works are distributed or communicated +to those persons or made available as an application intended for use over +a network. As an express condition for the grants of license hereunder, You +must treat any External Deployment by You of the Original Work or a +Derivative Work as a distribution under section 1(c). + +6) Attribution Rights. You must retain, in the Source Code of any Derivative +Works that You create, all copyright, patent, or trademark notices from the +Source Code of the Original Work, as well as any notices of licensing and +any descriptive text identified therein as an "Attribution Notice." You must +cause the Source Code for any Derivative Works that You create to carry a +prominent Attribution Notice reasonably calculated to inform recipients that +You have modified the Original Work. + +7) Warranty of Provenance and Disclaimer of Warranty. Licensor warrants that +the copyright in and to the Original Work and the patent rights granted +herein by Licensor are owned by the Licensor or are sublicensed to You under +the terms of this License with the permission of the contributor(s) of those +copyrights and patent rights. Except as expressly stated in the immediately +preceding sentence, the Original Work is provided under this License on an +"AS IS" BASIS and WITHOUT WARRANTY, either express or implied, including, +without limitation, the warranties of non-infringement, merchantability or +fitness for a particular purpose. THE ENTIRE RISK AS TO THE QUALITY OF THE +ORIGINAL WORK IS WITH YOU. This DISCLAIMER OF WARRANTY constitutes an +essential part of this License. No license to the Original Work is granted +by this License except under this disclaimer. + +8) Limitation of Liability. Under no circumstances and under no legal theory, +whether in tort (including negligence), contract, or otherwise, shall the +Licensor be liable to anyone for any indirect, special, incidental, or +consequential damages of any character arising as a result of this License or +the use of the Original Work including, without limitation, damages for loss +of goodwill, work stoppage, computer failure or malfunction, or any and all +other commercial damages or losses. This limitation of liability shall not +apply to the extent applicable law prohibits such limitation. + +9) Acceptance and Termination. If, at any time, You expressly assented to +this License, that assent indicates your clear and irrevocable acceptance of +this License and all of its terms and conditions. If You distribute or +communicate copies of the Original Work or a Derivative Work, You must make +a reasonable effort under the circumstances to obtain the express assent of +recipients to the terms of this License. This License conditions your rights +to undertake the activities listed in Section 1, including your right to +create Derivative Works based upon the Original Work, and doing so without +honoring these terms and conditions is prohibited by copyright law and +international treaty. Nothing in this License is intended to affect copyright +exceptions and limitations (including "fair use" or "fair dealing"). This +License shall terminate immediately and You may no longer exercise any of the +rights granted to You by this License upon your failure to honor the +conditions in Section 1(c). + +10) Termination for Patent Action. This License shall terminate automatically +and You may no longer exercise any of the rights granted to You by this +License as of the date You commence an action, including a cross-claim or +counterclaim, against Licensor or any licensee alleging that the Original +Work infringes a patent. This termination provision shall not apply for an +action alleging patent infringement by combinations of the Original Work with +other software or hardware. + +11) Jurisdiction, Venue and Governing Law. Any action or suit relating to +this License may be brought only in the courts of a jurisdiction wherein the +Licensor resides or in which Licensor conducts its primary business, and +under the laws of that jurisdiction excluding its conflict-of-law provisions. +The application of the United Nations Convention on Contracts for the +International Sale of Goods is expressly excluded. Any use of the Original +Work outside the scope of this License or after its termination shall be +subject to the requirements and penalties of copyright or patent law in the +appropriate jurisdiction. This section shall survive the termination of this +License. + +12) Attorneys' Fees. In any action to enforce the terms of this License or +seeking damages relating thereto, the prevailing party shall be entitled to +recover its costs and expenses, including, without limitation, reasonable +attorneys' fees and costs incurred in connection with such action, including +any appeal of such action. This section shall survive the termination of +this License. + +13) Miscellaneous. If any provision of this License is held to be +unenforceable, such provision shall be reformed only to the extent +necessary to make it enforceable. + +14) Definition of "You" in This License. "You" throughout this License, +whether in upper or lower case, means an individual or a legal entity +exercising rights under, and complying with all of the terms of, this +License. For legal entities, "You" includes any entity that controls, +is controlled by, or is under common control with you. For purposes of +this definition, "control" means (i) the power, direct or indirect, to +cause the direction or management of such entity, whether by contract or +otherwise, or (ii) ownership of fifty percent (50%) or more of the +outstanding shares, or (iii) beneficial ownership of such entity. + +15) Right to Use. You may use the Original Work in all ways not +otherwise restricted or conditioned by this License or by law, and +Licensor promises not to interfere with or be responsible for such +uses by You. + +16) Modification of This License. This License is Copyright © 2005 +Lawrence Rosen. Permission is granted to copy, distribute, or +communicate this License without modification. Nothing in this License +permits You to modify this License as applied to the Original Work or +to Derivative Works. However, You may modify the text of this License +and copy, distribute or communicate your modified version (the "Modified +License") and apply it to other original works of authorship subject to +the following conditions: (i) You may not indicate in any way that your +Modified License is the "Open Software License" or "OSL" and you may not +use those names in the name of your Modified License; (ii) You must replace +the notice specified in the first paragraph above with the notice +"Licensed under " or with a notice of your +own that is not confusingly similar to the notice in this License; and +(iii) You may not claim that your original works are open source software +unless your Modified License has been approved by Open Source Initiative +(OSI) and You comply with its license review and certification process. diff --git a/README.md b/README.md new file mode 100644 index 0000000..bbc7b1d --- /dev/null +++ b/README.md @@ -0,0 +1,13 @@ +# The Linux Kernel Module Programming Guide + +This project keeps the Linux Kernel Module Programming Guide reasonably up to date, with working examples for recent kernel versions. +The guide has been around since 2001 and most copies of it on the web only describe old 2.6.x kernels. + +The original guide may be found at http://www.tldp.org/LDP/lkmpg/ + +## License + +The work is released under the Open Software License (OSL) 3.0. +Use of this work is governed by a copyleft license that can be found in the LICENSE file. + +The complementary sample code is licensed under GNU GPL version 2, as same as Linux kernel.
