It is numbered 2 25*4ed51764SThomas Gleixnerbecause it goes with version 2 of the ordinary GPL.] 26*4ed51764SThomas Gleixner 27*4ed51764SThomas GleixnerPreamble 28*4ed51764SThomas Gleixner 29*4ed51764SThomas GleixnerThe licenses for most software are designed to take away your freedom to 30*4ed51764SThomas Gleixnershare and change it. By contrast, the GNU General Public Licenses are 31*4ed51764SThomas Gleixnerintended to guarantee your freedom to share and change free software--to 32*4ed51764SThomas Gleixnermake sure the software is free for all its users. 33*4ed51764SThomas Gleixner 34*4ed51764SThomas GleixnerThis license, the Library General Public License, applies to some specially 35*4ed51764SThomas Gleixnerdesignated Free Software Foundation software, and to any other libraries 36*4ed51764SThomas Gleixnerwhose authors decide to use it. You can use it for your libraries, too. 37*4ed51764SThomas Gleixner 38*4ed51764SThomas GleixnerWhen we speak of free software, we are referring to freedom, not price. Our 39*4ed51764SThomas GleixnerGeneral Public Licenses are designed to make sure that you have the freedom 40*4ed51764SThomas Gleixnerto distribute copies of free software (and charge for this service if you 41*4ed51764SThomas Gleixnerwish), that you receive source code or can get it if you want it, that you 42*4ed51764SThomas Gleixnercan change the software or use pieces of it in new free programs; and that 43*4ed51764SThomas Gleixneryou know you can do these things. 44*4ed51764SThomas Gleixner 45*4ed51764SThomas GleixnerTo protect your rights, we need to make restrictions that forbid anyone to 46*4ed51764SThomas Gleixnerdeny you these rights or to ask you to surrender the rights. These 47*4ed51764SThomas Gleixnerrestrictions translate to certain responsibilities for you if you 48*4ed51764SThomas Gleixnerdistribute copies of the library, or if you modify it. 49*4ed51764SThomas Gleixner 50*4ed51764SThomas GleixnerFor example, if you distribute copies of the library, whether gratis or for 51*4ed51764SThomas Gleixnera fee, you must give the recipients all the rights that we gave you. You 52*4ed51764SThomas Gleixnermust make sure that they, too, receive or can get the source code. If you 53*4ed51764SThomas Gleixnerlink a program with the library, you must provide complete object files to 54*4ed51764SThomas Gleixnerthe recipients so that they can relink them with the library, after making 55*4ed51764SThomas Gleixnerchanges to the library and recompiling it. And you must show them these 56*4ed51764SThomas Gleixnerterms so they know their rights. 57*4ed51764SThomas Gleixner 58*4ed51764SThomas GleixnerOur method of protecting your rights has two steps: (1) copyright the 59*4ed51764SThomas Gleixnerlibrary, and (2) offer you this license which gives you legal permission to 60*4ed51764SThomas Gleixnercopy, distribute and/or modify the library. 61*4ed51764SThomas Gleixner 62*4ed51764SThomas GleixnerAlso, for each distributor's protection, we want to make certain that 63*4ed51764SThomas Gleixnereveryone understands that there is no warranty for this free library. If 64*4ed51764SThomas Gleixnerthe library is modified by someone else and passed on, we want its 65*4ed51764SThomas Gleixnerrecipients to know that what they have is not the original version, so that 66*4ed51764SThomas Gleixnerany problems introduced by others will not reflect on the original authors' 67*4ed51764SThomas Gleixnerreputations. 68*4ed51764SThomas Gleixner 69*4ed51764SThomas GleixnerFinally, any free program is threatened constantly by software patents. We 70*4ed51764SThomas Gleixnerwish to avoid the danger that companies distributing free software will 71*4ed51764SThomas Gleixnerindividually obtain patent licenses, thus in effect transforming the 72*4ed51764SThomas Gleixnerprogram into proprietary software. To prevent this, we have made it clear 73*4ed51764SThomas Gleixnerthat any patent must be licensed for everyone's free use or not licensed at 74*4ed51764SThomas Gleixnerall. 75*4ed51764SThomas Gleixner 76*4ed51764SThomas GleixnerMost GNU software, including some libraries, is covered by the ordinary GNU 77*4ed51764SThomas GleixnerGeneral Public License, which was designed for utility programs. This 78*4ed51764SThomas Gleixnerlicense, the GNU Library General Public License, applies to certain 79*4ed51764SThomas Gleixnerdesignated libraries. This license is quite different from the ordinary 80*4ed51764SThomas Gleixnerone; be sure to read it in full, and don't assume that anything in it is 81*4ed51764SThomas Gleixnerthe same as in the ordinary license. 82*4ed51764SThomas Gleixner 83*4ed51764SThomas GleixnerThe reason we have a separate public license for some libraries is that 84*4ed51764SThomas Gleixnerthey blur the distinction we usually make between modifying or adding to a 85*4ed51764SThomas Gleixnerprogram and simply using it. Linking a program with a library, without 86*4ed51764SThomas Gleixnerchanging the library, is in some sense simply using the library, and is 87*4ed51764SThomas Gleixneranalogous to running a utility program or application program. However, in 88*4ed51764SThomas Gleixnera textual and legal sense, the linked executable is a combined work, a 89*4ed51764SThomas Gleixnerderivative of the original library, and the ordinary General Public License 90*4ed51764SThomas Gleixnertreats it as such. 91*4ed51764SThomas Gleixner 92*4ed51764SThomas GleixnerBecause of this blurred distinction, using the ordinary General Public 93*4ed51764SThomas GleixnerLicense for libraries did not effectively promote software sharing, because 94*4ed51764SThomas Gleixnermost developers did not use the libraries. We concluded that weaker 95*4ed51764SThomas Gleixnerconditions might promote sharing better. 96*4ed51764SThomas Gleixner 97*4ed51764SThomas GleixnerHowever, unrestricted linking of non-free programs would deprive the users 98*4ed51764SThomas Gleixnerof those programs of all benefit from the free status of the libraries 99*4ed51764SThomas Gleixnerthemselves. This Library General Public License is intended to permit 100*4ed51764SThomas Gleixnerdevelopers of non-free programs to use free libraries, while preserving 101*4ed51764SThomas Gleixneryour freedom as a user of such programs to change the free libraries that 102*4ed51764SThomas Gleixnerare incorporated in them. (We have not seen how to achieve this as regards 103*4ed51764SThomas Gleixnerchanges in header files, but we have achieved it as regards changes in the 104*4ed51764SThomas Gleixneractual functions of the Library.) The hope is that this will lead to faster 105*4ed51764SThomas Gleixnerdevelopment of free libraries. 106*4ed51764SThomas Gleixner 107*4ed51764SThomas GleixnerThe precise terms and conditions for copying, distribution and modification 108*4ed51764SThomas Gleixnerfollow. Pay close attention to the difference between a "work based on the 109*4ed51764SThomas Gleixnerlibrary" and a "work that uses the library". The former contains code 110*4ed51764SThomas Gleixnerderived from the library, while the latter only works together with the 111*4ed51764SThomas Gleixnerlibrary. 112*4ed51764SThomas Gleixner 113*4ed51764SThomas GleixnerNote that it is possible for a library to be covered by the ordinary 114*4ed51764SThomas GleixnerGeneral Public License rather than by this special one. 115*4ed51764SThomas Gleixner 116*4ed51764SThomas GleixnerTERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 117*4ed51764SThomas Gleixner 118*4ed51764SThomas Gleixner0. This License Agreement applies to any software library which contains a 119*4ed51764SThomas Gleixner notice placed by the copyright holder or other authorized party saying 120*4ed51764SThomas Gleixner it may be distributed under the terms of this Library General Public 121*4ed51764SThomas Gleixner License (also called "this License"). Each licensee is addressed as 122*4ed51764SThomas Gleixner "you". 123*4ed51764SThomas Gleixner 124*4ed51764SThomas Gleixner A "library" means a collection of software functions and/or data 125*4ed51764SThomas Gleixner prepared so as to be conveniently linked with application programs 126*4ed51764SThomas Gleixner (which use some of those functions and data) to form executables. 127*4ed51764SThomas Gleixner 128*4ed51764SThomas Gleixner The "Library", below, refers to any such software library or work which 129*4ed51764SThomas Gleixner has been distributed under these terms. A "work based on the Library" 130*4ed51764SThomas Gleixner means either the Library or any derivative work under copyright law: 131*4ed51764SThomas Gleixner that is to say, a work containing the Library or a portion of it, either 132*4ed51764SThomas Gleixner verbatim or with modifications and/or translated straightforwardly into 133*4ed51764SThomas Gleixner another language. (Hereinafter, translation is included without 134*4ed51764SThomas Gleixner limitation in the term "modification".) 135*4ed51764SThomas Gleixner 136*4ed51764SThomas Gleixner "Source code" for a work means the preferred form of the work for making 137*4ed51764SThomas Gleixner modifications to it. For a library, complete source code means all the 138*4ed51764SThomas Gleixner source code for all modules it contains, plus any associated interface 139*4ed51764SThomas Gleixner definition files, plus the scripts used to control compilation and 140*4ed51764SThomas Gleixner installation of the library. 141*4ed51764SThomas Gleixner 142*4ed51764SThomas Gleixner Activities other than copying, distribution and modification are not 143*4ed51764SThomas Gleixner covered by this License; they are outside its scope. The act of running 144*4ed51764SThomas Gleixner a program using the Library is not restricted, and output from such a 145*4ed51764SThomas Gleixner program is covered only if its contents constitute a work based on the 146*4ed51764SThomas Gleixner Library (independent of the use of the Library in a tool for writing 147*4ed51764SThomas Gleixner it). Whether that is true depends on what the Library does and what the 148*4ed51764SThomas Gleixner program that uses the Library does. 149*4ed51764SThomas Gleixner 150*4ed51764SThomas Gleixner1. You may copy and distribute verbatim copies of the Library's complete 151*4ed51764SThomas Gleixner source code as you receive it, in any medium, provided that you 152*4ed51764SThomas Gleixner conspicuously and appropriately publish on each copy an appropriate 153*4ed51764SThomas Gleixner copyright notice and disclaimer of warranty; keep intact all the notices 154*4ed51764SThomas Gleixner that refer to this License and to the absence of any warranty; and 155*4ed51764SThomas Gleixner distribute a copy of this License along with the Library. 156*4ed51764SThomas Gleixner 157*4ed51764SThomas Gleixner You may charge a fee for the physical act of transferring a copy, and 158*4ed51764SThomas Gleixner you may at your option offer warranty protection in exchange for a fee. 159*4ed51764SThomas Gleixner 160*4ed51764SThomas Gleixner2. You may modify your copy or copies of the Library or any portion of it, 161*4ed51764SThomas Gleixner thus forming a work based on the Library, and copy and distribute such 162*4ed51764SThomas Gleixner modifications or work under the terms of Section 1 above, provided that 163*4ed51764SThomas Gleixner you also meet all of these conditions: 164*4ed51764SThomas Gleixner 165*4ed51764SThomas Gleixner a) The modified work must itself be a software library. 166*4ed51764SThomas Gleixner 167*4ed51764SThomas Gleixner b) You must cause the files modified to carry prominent notices stating 168*4ed51764SThomas Gleixner that you changed the files and the date of any change. 169*4ed51764SThomas Gleixner 170*4ed51764SThomas Gleixner c) You must cause the whole of the work to be licensed at no charge to 171*4ed51764SThomas Gleixner all third parties under the terms of this License. 172*4ed51764SThomas Gleixner 173*4ed51764SThomas Gleixner d) If a facility in the modified Library refers to a function or a table 174*4ed51764SThomas Gleixner of data to be supplied by an application program that uses the 175*4ed51764SThomas Gleixner facility, other than as an argument passed when the facility is 176*4ed51764SThomas Gleixner invoked, then you must make a good faith effort to ensure that, in 177*4ed51764SThomas Gleixner the event an application does not supply such function or table, the 178*4ed51764SThomas Gleixner facility still operates, and performs whatever part of its purpose 179*4ed51764SThomas Gleixner remains meaningful. 180*4ed51764SThomas Gleixner 181*4ed51764SThomas Gleixner (For example, a function in a library to compute square roots has a 182*4ed51764SThomas Gleixner purpose that is entirely well-defined independent of the 183*4ed51764SThomas Gleixner application. Therefore, Subsection 2d requires that any 184*4ed51764SThomas Gleixner application-supplied function or table used by this function must be 185*4ed51764SThomas Gleixner optional: if the application does not supply it, the square root 186*4ed51764SThomas Gleixner function must still compute square roots.) 187*4ed51764SThomas Gleixner 188*4ed51764SThomas Gleixner These requirements apply to the modified work as a whole. If 189*4ed51764SThomas Gleixner identifiable sections of that work are not derived from the Library, and 190*4ed51764SThomas Gleixner can be reasonably considered independent and separate works in 191*4ed51764SThomas Gleixner themselves, then this License, and its terms, do not apply to those 192*4ed51764SThomas Gleixner sections when you distribute them as separate works. But when you 193*4ed51764SThomas Gleixner distribute the same sections as part of a whole which is a work based on 194*4ed51764SThomas Gleixner the Library, the distribution of the whole must be on the terms of this 195*4ed51764SThomas Gleixner License, whose permissions for other licensees extend to the entire 196*4ed51764SThomas Gleixner whole, and thus to each and every part regardless of who wrote it. 197*4ed51764SThomas Gleixner 198*4ed51764SThomas Gleixner Thus, it is not the intent of this section to claim rights or contest 199*4ed51764SThomas Gleixner your rights to work written entirely by you; rather, the intent is to 200*4ed51764SThomas Gleixner exercise the right to control the distribution of derivative or 201*4ed51764SThomas Gleixner collective works based on the Library. 202*4ed51764SThomas Gleixner 203*4ed51764SThomas Gleixner In addition, mere aggregation of another work not based on the Library 204*4ed51764SThomas Gleixner with the Library (or with a work based on the Library) on a volume of a 205*4ed51764SThomas Gleixner storage or distribution medium does not bring the other work under the 206*4ed51764SThomas Gleixner scope of this License. 207*4ed51764SThomas Gleixner 208*4ed51764SThomas Gleixner3. You may opt to apply the terms of the ordinary GNU General Public 209*4ed51764SThomas Gleixner License instead of this License to a given copy of the Library. To do 210*4ed51764SThomas Gleixner this, you must alter all the notices that refer to this License, so that 211*4ed51764SThomas Gleixner they refer to the ordinary GNU General Public License, version 2, 212*4ed51764SThomas Gleixner instead of to this License. (If a newer version than version 2 of the 213*4ed51764SThomas Gleixner ordinary GNU General Public License has appeared, then you can specify 214*4ed51764SThomas Gleixner that version instead if you wish.) Do not make any other change in these 215*4ed51764SThomas Gleixner notices. 216*4ed51764SThomas Gleixner 217*4ed51764SThomas Gleixner Once this change is made in a given copy, it is irreversible for that 218*4ed51764SThomas Gleixner copy, so the ordinary GNU General Public License applies to all 219*4ed51764SThomas Gleixner subsequent copies and derivative works made from that copy. 220*4ed51764SThomas Gleixner 221*4ed51764SThomas Gleixner This option is useful when you wish to copy part of the code of the 222*4ed51764SThomas Gleixner Library into a program that is not a library. 223*4ed51764SThomas Gleixner 224*4ed51764SThomas Gleixner4. You may copy and distribute the Library (or a portion or derivative of 225*4ed51764SThomas Gleixner it, under Section 2) in object code or executable form under the terms 226*4ed51764SThomas Gleixner of Sections 1 and 2 above provided that you accompany it with the 227*4ed51764SThomas Gleixner complete corresponding machine-readable source code, which must be 228*4ed51764SThomas Gleixner distributed under the terms of Sections 1 and 2 above on a medium 229*4ed51764SThomas Gleixner customarily used for software interchange. 230*4ed51764SThomas Gleixner 231*4ed51764SThomas Gleixner If distribution of object code is made by offering access to copy from a 232*4ed51764SThomas Gleixner designated place, then offering equivalent access to copy the source 233*4ed51764SThomas Gleixner code from the same place satisfies the requirement to distribute the 234*4ed51764SThomas Gleixner source code, even though third parties are not compelled to copy the 235*4ed51764SThomas Gleixner source along with the object code. 236*4ed51764SThomas Gleixner 237*4ed51764SThomas Gleixner5. A program that contains no derivative of any portion of the Library, but 238*4ed51764SThomas Gleixner is designed to work with the Library by being compiled or linked with 239*4ed51764SThomas Gleixner it, is called a "work that uses the Library". Such a work, in isolation, 240*4ed51764SThomas Gleixner is not a derivative work of the Library, and therefore falls outside the 241*4ed51764SThomas Gleixner scope of this License. 242*4ed51764SThomas Gleixner 243*4ed51764SThomas Gleixner However, linking a "work that uses the Library" with the Library creates 244*4ed51764SThomas Gleixner an executable that is a derivative of the Library (because it contains 245*4ed51764SThomas Gleixner portions of the Library), rather than a "work that uses the 246*4ed51764SThomas Gleixner library". The executable is therefore covered by this License. Section 6 247*4ed51764SThomas Gleixner states terms for distribution of such executables. 248*4ed51764SThomas Gleixner 249*4ed51764SThomas Gleixner When a "work that uses the Library" uses material from a header file 250*4ed51764SThomas Gleixner that is part of the Library, the object code for the work may be a 251*4ed51764SThomas Gleixner derivative work of the Library even though the source code is 252*4ed51764SThomas Gleixner not. Whether this is true is especially significant if the work can be 253*4ed51764SThomas Gleixner linked without the Library, or if the work is itself a library. The 254*4ed51764SThomas Gleixner threshold for this to be true is not precisely defined by law. 255*4ed51764SThomas Gleixner 256*4ed51764SThomas Gleixner If such an object file uses only numerical parameters, data structure 257*4ed51764SThomas Gleixner layouts and accessors, and small macros and small inline functions (ten 258*4ed51764SThomas Gleixner lines or less in length), then the use of the object file is 259*4ed51764SThomas Gleixner unrestricted, regardless of whether it is legally a derivative 260*4ed51764SThomas Gleixner work. (Executables containing this object code plus portions of the 261*4ed51764SThomas Gleixner Library will still fall under Section 6.) 262*4ed51764SThomas Gleixner 263*4ed51764SThomas Gleixner Otherwise, if the work is a derivative of the Library, you may 264*4ed51764SThomas Gleixner distribute the object code for the work under the terms of Section 265*4ed51764SThomas Gleixner 6. Any executables containing that work also fall under Section 6, 266*4ed51764SThomas Gleixner whether or not they are linked directly with the Library itself. 267*4ed51764SThomas Gleixner 268*4ed51764SThomas Gleixner6. As an exception to the Sections above, you may also compile or link a 269*4ed51764SThomas Gleixner "work that uses the Library" with the Library to produce a work 270*4ed51764SThomas Gleixner containing portions of the Library, and distribute that work under terms 271*4ed51764SThomas Gleixner of your choice, provided that the terms permit modification of the work 272*4ed51764SThomas Gleixner for the customer's own use and reverse engineering for debugging such 273*4ed51764SThomas Gleixner modifications. 274*4ed51764SThomas Gleixner 275*4ed51764SThomas Gleixner You must give prominent notice with each copy of the work that the 276*4ed51764SThomas Gleixner Library is used in it and that the Library and its use are covered by 277*4ed51764SThomas Gleixner this License. You must supply a copy of this License. If the work during 278*4ed51764SThomas Gleixner execution displays copyright notices, you must include the copyright 279*4ed51764SThomas Gleixner notice for the Library among them, as well as a reference directing the 280*4ed51764SThomas Gleixner user to the copy of this License. Also, you must do one of these things: 281*4ed51764SThomas Gleixner 282*4ed51764SThomas Gleixner a) Accompany the work with the complete corresponding machine-readable 283*4ed51764SThomas Gleixner source code for the Library including whatever changes were used in 284*4ed51764SThomas Gleixner the work (which must be distributed under Sections 1 and 2 above); 285*4ed51764SThomas Gleixner and, if the work is an executable linked with the Library, with the 286*4ed51764SThomas Gleixner complete machine-readable "work that uses the Library", as object 287*4ed51764SThomas Gleixner code and/or source code, so that the user can modify the Library and 288*4ed51764SThomas Gleixner then relink to produce a modified executable containing the modified 289*4ed51764SThomas Gleixner Library. (It is understood that the user who changes the contents of 290*4ed51764SThomas Gleixner definitions files in the Library will not necessarily be able to 291*4ed51764SThomas Gleixner recompile the application to use the modified definitions.) 292*4ed51764SThomas Gleixner 293*4ed51764SThomas Gleixner b) Accompany the work with a written offer, valid for at least three 294*4ed51764SThomas Gleixner years, to give the same user the materials specified in Subsection 295*4ed51764SThomas Gleixner 6a, above, for a charge no more than the cost of performing this 296*4ed51764SThomas Gleixner distribution. 297*4ed51764SThomas Gleixner 298*4ed51764SThomas Gleixner c) If distribution of the work is made by offering access to copy from a 299*4ed51764SThomas Gleixner designated place, offer equivalent access to copy the above specified 300*4ed51764SThomas Gleixner materials from the same place. 301*4ed51764SThomas Gleixner 302*4ed51764SThomas Gleixner d) Verify that the user has already received a copy of these materials 303*4ed51764SThomas Gleixner or that you have already sent this user a copy. 304*4ed51764SThomas Gleixner 305*4ed51764SThomas Gleixner For an executable, the required form of the "work that uses the Library" 306*4ed51764SThomas Gleixner must include any data and utility programs needed for reproducing the 307*4ed51764SThomas Gleixner executable from it. However, as a special exception, the source code 308*4ed51764SThomas Gleixner distributed need not include anything that is normally distributed (in 309*4ed51764SThomas Gleixner either source or binary form) with the major components (compiler, 310*4ed51764SThomas Gleixner kernel, and so on) of the operating system on which the executable runs, 311*4ed51764SThomas Gleixner unless that component itself accompanies the executable. 312*4ed51764SThomas Gleixner 313*4ed51764SThomas Gleixner It may happen that this requirement contradicts the license restrictions 314*4ed51764SThomas Gleixner of other proprietary libraries that do not normally accompany the 315*4ed51764SThomas Gleixner operating system. Such a contradiction means you cannot use both them 316*4ed51764SThomas Gleixner and the Library together in an executable that you distribute. 317*4ed51764SThomas Gleixner 318*4ed51764SThomas Gleixner7. You may place library facilities that are a work based on the Library 319*4ed51764SThomas Gleixner side-by-side in a single library together with other library facilities 320*4ed51764SThomas Gleixner not covered by this License, and distribute such a combined library, 321*4ed51764SThomas Gleixner provided that the separate distribution of the work based on the Library 322*4ed51764SThomas Gleixner and of the other library facilities is otherwise permitted, and provided 323*4ed51764SThomas Gleixner that you do these two things: 324*4ed51764SThomas Gleixner 325*4ed51764SThomas Gleixner a) Accompany the combined library with a copy of the same work based on 326*4ed51764SThomas Gleixner the Library, uncombined with any other library facilities. This must 327*4ed51764SThomas Gleixner be distributed under the terms of the Sections above. 328*4ed51764SThomas Gleixner 329*4ed51764SThomas Gleixner b) Give prominent notice with the combined library of the fact that part 330*4ed51764SThomas Gleixner of it is a work based on the Library, and explaining where to find 331*4ed51764SThomas Gleixner the accompanying uncombined form of the same work. 332*4ed51764SThomas Gleixner 333*4ed51764SThomas Gleixner8. You may not copy, modify, sublicense, link with, or distribute the 334*4ed51764SThomas Gleixner Library except as expressly provided under this License. Any attempt 335*4ed51764SThomas Gleixner otherwise to copy, modify, sublicense, link with, or distribute the 336*4ed51764SThomas Gleixner Library is void, and will automatically terminate your rights under this 337*4ed51764SThomas Gleixner License. However, parties who have received copies, or rights, from you 338*4ed51764SThomas Gleixner under this License will not have their licenses terminated so long as 339*4ed51764SThomas Gleixner such parties remain in full compliance. 340*4ed51764SThomas Gleixner 341*4ed51764SThomas Gleixner9. You are not required to accept this License, since you have not signed 342*4ed51764SThomas Gleixner it. However, nothing else grants you permission to modify or distribute 343*4ed51764SThomas Gleixner the Library or its derivative works. These actions are prohibited by law 344*4ed51764SThomas Gleixner if you do not accept this License. Therefore, by modifying or 345*4ed51764SThomas Gleixner distributing the Library (or any work based on the Library), you 346*4ed51764SThomas Gleixner indicate your acceptance of this License to do so, and all its terms and 347*4ed51764SThomas Gleixner conditions for copying, distributing or modifying the Library or works 348*4ed51764SThomas Gleixner based on it. 349*4ed51764SThomas Gleixner 350*4ed51764SThomas Gleixner10. Each time you redistribute the Library (or any work based on the 351*4ed51764SThomas Gleixner Library), the recipient automatically receives a license from the 352*4ed51764SThomas Gleixner original licensor to copy, distribute, link with or modify the Library 353*4ed51764SThomas Gleixner subject to these terms and conditions. You may not impose any further 354*4ed51764SThomas Gleixner restrictions on the recipients' exercise of the rights granted 355*4ed51764SThomas Gleixner herein. You are not responsible for enforcing compliance by third 356*4ed51764SThomas Gleixner parties to this License. 357*4ed51764SThomas Gleixner 358*4ed51764SThomas Gleixner11. If, as a consequence of a court judgment or allegation of patent 359*4ed51764SThomas Gleixner infringement or for any other reason (not limited to patent issues), 360*4ed51764SThomas Gleixner conditions are imposed on you (whether by court order, agreement or 361*4ed51764SThomas Gleixner otherwise) that contradict the conditions of this License, they do not 362*4ed51764SThomas Gleixner excuse you from the conditions of this License. If you cannot 363*4ed51764SThomas Gleixner distribute so as to satisfy simultaneously your obligations under this 364*4ed51764SThomas Gleixner License and any other pertinent obligations, then as a consequence you 365*4ed51764SThomas Gleixner may not distribute the Library at all. For example, if a patent license 366*4ed51764SThomas Gleixner would not permit royalty-free redistribution of the Library by all 367*4ed51764SThomas Gleixner those who receive copies directly or indirectly through you, then the 368*4ed51764SThomas Gleixner only way you could satisfy both it and this License would be to refrain 369*4ed51764SThomas Gleixner entirely from distribution of the Library. 370*4ed51764SThomas Gleixner 371*4ed51764SThomas Gleixner If any portion of this section is held invalid or unenforceable under 372*4ed51764SThomas Gleixner any particular circumstance, the balance of the section is intended to 373*4ed51764SThomas Gleixner apply, and the section as a whole is intended to apply in other 374*4ed51764SThomas Gleixner circumstances. 375*4ed51764SThomas Gleixner 376*4ed51764SThomas Gleixner It is not the purpose of this section to induce you to infringe any 377*4ed51764SThomas Gleixner patents or other property right claims or to contest validity of any 378*4ed51764SThomas Gleixner such claims; this section has the sole purpose of protecting the 379*4ed51764SThomas Gleixner integrity of the free software distribution system which is implemented 380*4ed51764SThomas Gleixner by public license practices. Many people have made generous 381*4ed51764SThomas Gleixner contributions to the wide range of software distributed through that 382*4ed51764SThomas Gleixner system in reliance on consistent application of that system; it is up 383*4ed51764SThomas Gleixner to the author/donor to decide if he or she is willing to distribute 384*4ed51764SThomas Gleixner software through any other system and a licensee cannot impose that 385*4ed51764SThomas Gleixner choice. 386*4ed51764SThomas Gleixner 387*4ed51764SThomas Gleixner This section is intended to make thoroughly clear what is believed to 388*4ed51764SThomas Gleixner be a consequence of the rest of this License. 389*4ed51764SThomas Gleixner 390*4ed51764SThomas Gleixner12. If the distribution and/or use of the Library is restricted in certain 391*4ed51764SThomas Gleixner countries either by patents or by copyrighted interfaces, the original 392*4ed51764SThomas Gleixner copyright holder who places the Library under this License may add an 393*4ed51764SThomas Gleixner explicit geographical distribution limitation excluding those 394*4ed51764SThomas Gleixner countries, so that distribution is permitted only in or among countries 395*4ed51764SThomas Gleixner not thus excluded. In such case, this License incorporates the 396*4ed51764SThomas Gleixner limitation as if written in the body of this License. 397*4ed51764SThomas Gleixner 398*4ed51764SThomas Gleixner13. The Free Software Foundation may publish revised and/or new versions of 399*4ed51764SThomas Gleixner the Library General Public License from time to time. Such new versions 400*4ed51764SThomas Gleixner will be similar in spirit to the present version, but may differ in 401*4ed51764SThomas Gleixner detail to address new problems or concerns. 402*4ed51764SThomas Gleixner 403*4ed51764SThomas Gleixner Each version is given a distinguishing version number. If the Library 404*4ed51764SThomas Gleixner specifies a version number of this License which applies to it and "any 405*4ed51764SThomas Gleixner later version", you have the option of following the terms and 406*4ed51764SThomas Gleixner conditions either of that version or of any later version published by 407*4ed51764SThomas Gleixner the Free Software Foundation. If the Library does not specify a license 408*4ed51764SThomas Gleixner version number, you may choose any version ever published by the Free 409*4ed51764SThomas Gleixner Software Foundation. 410*4ed51764SThomas Gleixner 411*4ed51764SThomas Gleixner14. If you wish to incorporate parts of the Library into other free 412*4ed51764SThomas Gleixner programs whose distribution conditions are incompatible with these, 413*4ed51764SThomas Gleixner write to the author to ask for permission. For software which is 414*4ed51764SThomas Gleixner copyrighted by the Free Software Foundation, write to the Free Software 415*4ed51764SThomas Gleixner Foundation; we sometimes make exceptions for this. Our decision will be 416*4ed51764SThomas Gleixner guided by the two goals of preserving the free status of all 417*4ed51764SThomas Gleixner derivatives of our free software and of promoting the sharing and reuse 418*4ed51764SThomas Gleixner of software generally. 419*4ed51764SThomas Gleixner 420*4ed51764SThomas GleixnerNO WARRANTY 421*4ed51764SThomas Gleixner 422*4ed51764SThomas Gleixner15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY 423*4ed51764SThomas Gleixner FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN 424*4ed51764SThomas Gleixner OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES 425*4ed51764SThomas Gleixner PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER 426*4ed51764SThomas Gleixner EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED 427*4ed51764SThomas Gleixner WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE 428*4ed51764SThomas Gleixner ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH 429*4ed51764SThomas Gleixner YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL 430*4ed51764SThomas Gleixner NECESSARY SERVICING, REPAIR OR CORRECTION. 431*4ed51764SThomas Gleixner 432*4ed51764SThomas Gleixner16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING 433*4ed51764SThomas Gleixner WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR 434*4ed51764SThomas Gleixner REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR 435*4ed51764SThomas Gleixner DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL 436*4ed51764SThomas Gleixner DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE LIBRARY 437*4ed51764SThomas Gleixner (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED 438*4ed51764SThomas Gleixner INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF 439*4ed51764SThomas Gleixner THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER OR 440*4ed51764SThomas Gleixner OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. 441*4ed51764SThomas Gleixner 442*4ed51764SThomas GleixnerEND OF TERMS AND CONDITIONS 443*4ed51764SThomas Gleixner 444*4ed51764SThomas GleixnerHow to Apply These Terms to Your New Libraries 445*4ed51764SThomas Gleixner 446*4ed51764SThomas GleixnerIf you develop a new library, and you want it to be of the greatest 447*4ed51764SThomas Gleixnerpossible use to the public, we recommend making it free software that 448*4ed51764SThomas Gleixnereveryone can redistribute and change. You can do so by permitting 449*4ed51764SThomas Gleixnerredistribution under these terms (or, alternatively, under the terms of the 450*4ed51764SThomas Gleixnerordinary General Public License). 451*4ed51764SThomas Gleixner 452*4ed51764SThomas GleixnerTo apply these terms, attach the following notices to the library.
