1 Copyright (c) 2003-2013 QLogic Corporation 2 QLogic Linux iSCSI Driver 3 4 This program includes a device driver for Linux 3.x. 5 You may modify and redistribute the device driver code under the 6 GNU General Public License (a copy of which is attached hereto as 7 Exhibit A) published by the Free Software Foundation (version 2). 8 9 10 EXHIBIT A 11 12 GNU GENERAL PUBLIC LICENSE 13 Version 2, June 1991 14 15 Copyright (C) 1989, 1991 Free Software Foundation, Inc. 16 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA 17 Everyone is permitted to copy and distribute verbatim copies 18 of this license document, but changing it is not allowed. 19 20 Preamble 21 22 The licenses for most software are designed to take away your 23 freedom to share and change it. By contrast, the GNU General Public 24 License is intended to guarantee your freedom to share and change free 25 software--to make sure the software is free for all its users. This 26 General Public License applies to most of the Free Software 27 Foundation's software and to any other program whose authors commit to 28 using it. (Some other Free Software Foundation software is covered by 29 the GNU Lesser General Public License instead.) You can apply it to 30 your programs, too. 31 32 When we speak of free software, we are referring to freedom, not 33 price. Our General Public Licenses are designed to make sure that you 34 have the freedom to distribute copies of free software (and charge for 35 this service if you wish), that you receive source code or can get it 36 if you want it, that you can change the software or use pieces of it 37 in new free programs; and that you know you can do these things. 38 39 To protect your rights, we need to make restrictions that forbid 40 anyone to deny you these rights or to ask you to surrender the rights. 41 These restrictions translate to certain responsibilities for you if you 42 distribute copies of the software, or if you modify it. 43 44 For example, if you distribute copies of such a program, whether 45 gratis or for a fee, you must give the recipients all the rights that 46 you have. You must make sure that they, too, receive or can get the 47 source code. And you must show them these terms so they know their 48 rights. 49 50 We protect your rights with two steps: (1) copyright the software, and 51 (2) offer you this license which gives you legal permission to copy, 52 distribute and/or modify the software. 53 54 Also, for each author's protection and ours, we want to make certain 55 that everyone understands that there is no warranty for this free 56 software. If the software is modified by someone else and passed on, we 57 want its recipients to know that what they have is not the original, so 58 that any problems introduced by others will not reflect on the original 59 authors' reputations. 60 61 Finally, any free program is threatened constantly by software 62 patents. We wish to avoid the danger that redistributors of a free 63 program will individually obtain patent licenses, in effect making the 64 program proprietary. To prevent this, we have made it clear that any 65 patent must be licensed for everyone's free use or not licensed at all. 66 67 The precise terms and conditions for copying, distribution and 68 modification follow. 69 70 GNU GENERAL PUBLIC LICENSE 71 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 72 73 0. This License applies to any program or other work which contains 74 a notice placed by the copyright holder saying it may be distributed 75 under the terms of this General Public License. The "Program", below, 76 refers to any such program or work, and a "work based on the Program" 77 means either the Program or any derivative work under copyright law: 78 that is to say, a work containing the Program or a portion of it, 79 either verbatim or with modifications and/or translated into another 80 language. (Hereinafter, translation is included without limitation in 81 the term "modification".) Each licensee is addressed as "you". 82 83 Activities other than copying, distribution and modification are not 84 covered by this License; they are outside its scope. The act of 85 running the Program is not restricted, and the output from the Program 86 is covered only if its contents constitute a work based on the 87 Program (independent of having been made by running the Program). 88 Whether that is true depends on what the Program does. 89 90 1. You may copy and distribute verbatim copies of the Program's 91 source code as you receive it, in any medium, provided that you 92 conspicuously and appropriately publish on each copy an appropriate 93 copyright notice and disclaimer of warranty; keep intact all the 94 notices that refer to this License and to the absence of any warranty; 95 and give any other recipients of the Program a copy of this License 96 along with the Program. 97 98 You may charge a fee for the physical act of transferring a copy, and 99 you may at your option offer warranty protection in exchange for a fee. 100 101 2. You may modify your copy or copies of the Program or any portion 102 of it, thus forming a work based on the Program, and copy and 103 distribute such modifications or work under the terms of Section 1 104 above, provided that you also meet all of these conditions: 105 106 a) You must cause the modified files to carry prominent notices 107 stating that you changed the files and the date of any change. 108 109 b) You must cause any work that you distribute or publish, that in 110 whole or in part contains or is derived from the Program or any 111 part thereof, to be licensed as a whole at no charge to all third 112 parties under the terms of this License. 113 114 c) If the modified program normally reads commands interactively 115 when run, you must cause it, when started running for such 116 interactive use in the most ordinary way, to print or display an 117 announcement including an appropriate copyright notice and a 118 notice that there is no warranty (or else, saying that you provide 119 a warranty) and that users may redistribute the program under 120 these conditions, and telling the user how to view a copy of this 121 License. (Exception: if the Program itself is interactive but 122 does not normally print such an announcement, your work based on 123 the Program is not required to print an announcement.) 124 125 These requirements apply to the modified work as a whole. If 126 identifiable sections of that work are not derived from the Program, 127 and can be reasonably considered independent and separate works in 128 themselves, then this License, and its terms, do not apply to those 129 sections when you distribute them as separate works. But when you 130 distribute the same sections as part of a whole which is a work based 131 on the Program, the distribution of the whole must be on the terms of 132 this License, whose permissions for other licensees extend to the 133 entire whole, and thus to each and every part regardless of who wrote it. 134 135 Thus, it is not the intent of this section to claim rights or contest 136 your rights to work written entirely by you; rather, the intent is to 137 exercise the right to control the distribution of derivative or 138 collective works based on the Program. 139 140 In addition, mere aggregation of another work not based on the Program 141 with the Program (or with a work based on the Program) on a volume of 142 a storage or distribution medium does not bring the other work under 143 the scope of this License. 144 145 3. You may copy and distribute the Program (or a work based on it, 146 under Section 2) in object code or executable form under the terms of 147 Sections 1 and 2 above provided that you also do one of the following: 148 149 a) Accompany it with the complete corresponding machine-readable 150 source code, which must be distributed under the terms of Sections 151 1 and 2 above on a medium customarily used for software interchange; or, 152 153 b) Accompany it with a written offer, valid for at least three 154 years, to give any third party, for a charge no more than your 155 cost of physically performing source distribution, a complete 156 machine-readable copy of the corresponding source code, to be 157 distributed under the terms of Sections 1 and 2 above on a medium 158 customarily used for software interchange; or, 159 160 c) Accompany it with the information you received as to the offer 161 to distribute corresponding source code. (This alternative is 162 allowed only for noncommercial distribution and only if you 163 received the program in object code or executable form with such 164 an offer, in accord with Subsection b above.) 165 166 The source code for a work means the preferred form of the work for 167 making modifications to it. For an executable work, complete source 168 code means all the source code for all modules it contains, plus any 169 associated interface definition files, plus the scripts used to 170 control compilation and installation of the executable. However, as a 171 special exception, the source code distributed need not include 172 anything that is normally distributed (in either source or binary 173 form) with the major components (compiler, kernel, and so on) of the 174 operating system on which the executable runs, unless that component 175 itself accompanies the executable. 176 177 If distribution of executable or object code is made by offering 178 access to copy from a designated place, then offering equivalent 179 access to copy the source code from the same place counts as 180 distribution of the source code, even though third parties are not 181 compelled to copy the source along with the object code. 182 183 4. You may not copy, modify, sublicense, or distribute the Program 184 except as expressly provided under this License. Any attempt 185 otherwise to copy, modify, sublicense or distribute the Program is 186 void, and will automatically terminate your rights under this License. 187 However, parties who have received copies, or rights, from you under 188 this License will not have their licenses terminated so long as such 189 parties remain in full compliance. 190 191 5. You are not required to accept this License, since you have not 192 signed it. However, nothing else grants you permission to modify or 193 distribute the Program or its derivative works. These actions are 194 prohibited by law if you do not accept this License. Therefore, by 195 modifying or distributing the Program (or any work based on the 196 Program), you indicate your acceptance of this License to do so, and 197 all its terms and conditions for copying, distributing or modifying 198 the Program or works based on it. 199 200 6. Each time you redistribute the Program (or any work based on the 201 Program), the recipient automatically receives a license from the 202 original licensor to copy, distribute or modify the Program subject to 203 these terms and conditions. You may not impose any further 204 restrictions on the recipients' exercise of the rights granted herein. 205 You are not responsible for enforcing compliance by third parties to 206 this License. 207 208 7. If, as a consequence of a court judgment or allegation of patent 209 infringement or for any other reason (not limited to patent issues), 210 conditions are imposed on you (whether by court order, agreement or 211 otherwise) that contradict the conditions of this License, they do not 212 excuse you from the conditions of this License. If you cannot 213 distribute so as to satisfy simultaneously your obligations under this 214 License and any other pertinent obligations, then as a consequence you 215 may not distribute the Program at all. For example, if a patent 216 license would not permit royalty-free redistribution of the Program by 217 all those who receive copies directly or indirectly through you, then 218 the only way you could satisfy both it and this License would be to 219 refrain entirely from distribution of the Program. 220 221 If any portion of this section is held invalid or unenforceable under 222 any particular circumstance, the balance of the section is intended to 223 apply and the section as a whole is intended to apply in other 224 circumstances. 225 226 It is not the purpose of this section to induce you to infringe any 227 patents or other property right claims or to contest validity of any 228 such claims; this section has the sole purpose of protecting the 229 integrity of the free software distribution system, which is 230 implemented by public license practices. Many people have made 231 generous contributions to the wide range of software distributed 232 through that system in reliance on consistent application of that 233 system; it is up to the author/donor to decide if he or she is willing 234 to distribute software through any other system and a licensee cannot 235 impose that choice. 236 237 This section is intended to make thoroughly clear what is believed to 238 be a consequence of the rest of this License. 239 240 8. If the distribution and/or use of the Program is restricted in 241 certain countries either by patents or by copyrighted interfaces, the 242 original copyright holder who places the Program under this License 243 may add an explicit geographical distribution limitation excluding 244 those countries, so that distribution is permitted only in or among 245 countries not thus excluded. In such case, this License incorporates 246 the limitation as if written in the body of this License. 247 248 9. The Free Software Foundation may publish revised and/or new versions 249 of the General Public License from time to time. Such new versions will 250 be similar in spirit to the present version, but may differ in detail to 251 address new problems or concerns. 252 253 Each version is given a distinguishing version number. If the Program 254 specifies a version number of this License which applies to it and "any 255 later version", you have the option of following the terms and conditions 256 either of that version or of any later version published by the Free 257 Software Foundation. If the Program does not specify a version number of 258 this License, you may choose any version ever published by the Free Software 259 Foundation. 260 261 10. If you wish to incorporate parts of the Program into other free 262 programs whose distribution conditions are different, write to the author 263 to ask for permission. For software which is copyrighted by the Free 264 Software Foundation, write to the Free Software Foundation; we sometimes 265 make exceptions for this. Our decision will be guided by the two goals 266 of preserving the free status of all derivatives of our free software and 267 of promoting the sharing and reuse of software generally. 268 269 NO WARRANTY 270 271 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY 272 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN 273 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES 274 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED 275 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF 276 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS 277 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE 278 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, 279 REPAIR OR CORRECTION. 280 281 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING 282 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR 283 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, 284 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING 285 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED 286 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY 287 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER 288 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE 289 POSSIBILITY OF SUCH DAMAGES.
