By contrast, +the GNU General Public License is intended to guarantee your freedom to +share and change all versions of a program--to make sure it remains free +software for all its users. We, the Free Software Foundation, use the +GNU General Public License for most of our software; it applies also to +any other work released this way by its authors. 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 +them 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 prevent others from denying you +these rights or asking you to surrender the rights. Therefore, you have +certain responsibilities if you distribute copies of the software, or if +you modify it: responsibilities to respect the freedom of others. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must pass on to the recipients the same +freedoms that you received. 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. + + Developers that use the GNU GPL protect your rights with two steps: +(1) assert copyright on the software, and (2) offer you this License +giving you legal permission to copy, distribute and/or modify it. + + For the developers' and authors' protection, the GPL clearly explains +that there is no warranty for this free software. For both users' and +authors' sake, the GPL requires that modified versions be marked as +changed, so that their problems will not be attributed erroneously to +authors of previous versions. + + Some devices are designed to deny users access to install or run +modified versions of the software inside them, although the manufacturer +can do so. This is fundamentally incompatible with the aim of +protecting users' freedom to change the software. The systematic +pattern of such abuse occurs in the area of products for individuals to +use, which is precisely where it is most unacceptable. Therefore, we +have designed this version of the GPL to prohibit the practice for those +products. If such problems arise substantially in other domains, we +stand ready to extend this provision to those domains in future versions +of the GPL, as needed to protect the freedom of users. + + Finally, every program is threatened constantly by software patents. +States should not allow patents to restrict development and use of +software on general-purpose computers, but in those that do, we wish to +avoid the special danger that patents applied to a free program could +make it effectively proprietary. To prevent this, the GPL assures that +patents cannot be used to render the program non-free. + + The precise terms and conditions for copying, distribution and +modification follow. + + TERMS AND CONDITIONS + + 0. Definitions. + + "This License" refers to version 3 of the GNU General Public License. + + "Copyright" also means copyright-like laws that apply to other kinds of +works, such as semiconductor masks. + + "The Program" refers to any copyrightable work licensed under this +License. Each licensee is addressed as "you". "Licensees" and +"recipients" may be individuals or organizations. + + To "modify" a work means to copy from or adapt all or part of the work +in a fashion requiring copyright permission, other than the making of an +exact copy. The resulting work is called a "modified version" of the +earlier work or a work "based on" the earlier work. + + A "covered work" means either the unmodified Program or a work based +on the Program. + + To "propagate" a work means to do anything with it that, without +permission, would make you directly or secondarily liable for +infringement under applicable copyright law, except executing it on a +computer or modifying a private copy. Propagation includes copying, +distribution (with or without modification), making available to the +public, and in some countries other activities as well. + + To "convey" a work means any kind of propagation that enables other +parties to make or receive copies. Mere interaction with a user through +a computer network, with no transfer of a copy, is not conveying. + + An interactive user interface displays "Appropriate Legal Notices" +to the extent that it includes a convenient and prominently visible +feature that (1) displays an appropriate copyright notice, and (2) +tells the user that there is no warranty for the work (except to the +extent that warranties are provided), that licensees may convey the +work under this License, and how to view a copy of this License. If +the interface presents a list of user commands or options, such as a +menu, a prominent item in the list meets this criterion. + + 1. Source Code. + + The "source code" for a work means the preferred form of the work +for making modifications to it. "Object code" means any non-source +form of a work. + + A "Standard Interface" means an interface that either is an official +standard defined by a recognized standards body, or, in the case of +interfaces specified for a particular programming language, one that +is widely used among developers working in that language. + + The "System Libraries" of an executable work include anything, other +than the work as a whole, that (a) is included in the normal form of +packaging a Major Component, but which is not part of that Major +Component, and (b) serves only to enable use of the work with that +Major Component, or to implement a Standard Interface for which an +implementation is available to the public in source code form. A +"Major Component", in this context, means a major essential component +(kernel, window system, and so on) of the specific operating system +(if any) on which the executable work runs, or a compiler used to +produce the work, or an object code interpreter used to run it. + + The "Corresponding Source" for a work in object code form means all +the source code needed to generate, install, and (for an executable +work) run the object code and to modify the work, including scripts to +control those activities. However, it does not include the work's +System Libraries, or general-purpose tools or generally available free +programs which are used unmodified in performing those activities but +which are not part of the work. For example, Corresponding Source +includes interface definition files associated with source files for +the work, and the source code for shared libraries and dynamically +linked subprograms that the work is specifically designed to require, +such as by intimate data communication or control flow between those +subprograms and other parts of the work. + + The Corresponding Source need not include anything that users +can regenerate automatically from other parts of the Corresponding +Source. + + The Corresponding Source for a work in source code form is that +same work. + + 2. Basic Permissions. + + All rights granted under this License are granted for the term of +copyright on the Program, and are irrevocable provided the stated +conditions are met. This License explicitly affirms your unlimited +permission to run the unmodified Program. The output from running a +covered work is covered by this License only if the output, given its +content, constitutes a covered work. This License acknowledges your +rights of fair use or other equivalent, as provided by copyright law. + + You may make, run and propagate covered works that you do not +convey, without conditions so long as your license otherwise remains +in force. You may convey covered works to others for the sole purpose +of having them make modifications exclusively for you, or provide you +with facilities for running those works, provided that you comply with +the terms of this License in conveying all material for which you do +not control copyright. Those thus making or running the covered works +for you must do so exclusively on your behalf, under your direction +and control, on terms that prohibit them from making any copies of +your copyrighted material outside their relationship with you. + + Conveying under any other circumstances is permitted solely under +the conditions stated below. Sublicensing is not allowed; section 10 +makes it unnecessary. + + 3. Protecting Users' Legal Rights From Anti-Circumvention Law. + + No covered work shall be deemed part of an effective technological +measure under any applicable law fulfilling obligations under article +11 of the WIPO copyright treaty adopted on 20 December 1996, or +similar laws prohibiting or restricting circumvention of such +measures. + + When you convey a covered work, you waive any legal power to forbid +circumvention of technological measures to the extent such circumvention +is effected by exercising rights under this License with respect to +the covered work, and you disclaim any intention to limit operation or +modification of the work as a means of enforcing, against the work's +users, your or third parties' legal rights to forbid circumvention of +technological measures. + + 4. Conveying Verbatim Copies. + + You may convey 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; +keep intact all notices stating that this License and any +non-permissive terms added in accord with section 7 apply to the code; +keep intact all notices of the absence of any warranty; and give all +recipients a copy of this License along with the Program. + + You may charge any price or no price for each copy that you convey, +and you may offer support or warranty protection for a fee. + + 5. Conveying Modified Source Versions. + + You may convey a work based on the Program, or the modifications to +produce it from the Program, in the form of source code under the +terms of section 4, provided that you also meet all of these conditions: + + a) The work must carry prominent notices stating that you modified + it, and giving a relevant date. + + b) The work must carry prominent notices stating that it is + released under this License and any conditions added under section + 7. This requirement modifies the requirement in section 4 to + "keep intact all notices". + + c) You must license the entire work, as a whole, under this + License to anyone who comes into possession of a copy. This + License will therefore apply, along with any applicable section 7 + additional terms, to the whole of the work, and all its parts, + regardless of how they are packaged. This License gives no + permission to license the work in any other way, but it does not + invalidate such permission if you have separately received it. + + d) If the work has interactive user interfaces, each must display + Appropriate Legal Notices; however, if the Program has interactive + interfaces that do not display Appropriate Legal Notices, your + work need not make them do so. + + A compilation of a covered work with other separate and independent +works, which are not by their nature extensions of the covered work, +and which are not combined with it such as to form a larger program, +in or on a volume of a storage or distribution medium, is called an +"aggregate" if the compilation and its resulting copyright are not +used to limit the access or legal rights of the compilation's users +beyond what the individual works permit. Inclusion of a covered work +in an aggregate does not cause this License to apply to the other +parts of the aggregate. + + 6. Conveying Non-Source Forms. + + You may convey a covered work in object code form under the terms +of sections 4 and 5, provided that you also convey the +machine-readable Corresponding Source under the terms of this License, +in one of these ways: + + a) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by the + Corresponding Source fixed on a durable physical medium + customarily used for software interchange. + + b) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by a + written offer, valid for at least three years and valid for as + long as you offer spare parts or customer support for that product + model, to give anyone who possesses the object code either (1) a + copy of the Corresponding Source for all the software in the + product that is covered by this License, on a durable physical + medium customarily used for software interchange, for a price no + more than your reasonable cost of physically performing this + conveying of source, or (2) access to copy the + Corresponding Source from a network server at no charge. + + c) Convey individual copies of the object code with a copy of the + written offer to provide the Corresponding Source. This + alternative is allowed only occasionally and noncommercially, and + only if you received the object code with such an offer, in accord + with subsection 6b. + + d) Convey the object code by offering access from a designated + place (gratis or for a charge), and offer equivalent access to the + Corresponding Source in the same way through the same place at no + further charge. You need not require recipients to copy the + Corresponding Source along with the object code. If the place to + copy the object code is a network server, the Corresponding Source + may be on a different server (operated by you or a third party) + that supports equivalent copying facilities, provided you maintain + clear directions next to the object code saying where to find the + Corresponding Source. Regardless of what server hosts the + Corresponding Source, you remain obligated to ensure that it is + available for as long as needed to satisfy these requirements. + + e) Convey the object code using peer-to-peer transmission, provided + you inform other peers where the object code and Corresponding + Source of the work are being offered to the general public at no + charge under subsection 6d. + + A separable portion of the object code, whose source code is excluded +from the Corresponding Source as a System Library, need not be +included in conveying the object code work. + + A "User Product" is either (1) a "consumer product", which means any +tangible personal property which is normally used for personal, family, +or household purposes, or (2) anything designed or sold for incorporation +into a dwelling. In determining whether a product is a consumer product, +doubtful cases shall be resolved in favor of coverage. For a particular +product received by a particular user, "normally used" refers to a +typical or common use of that class of product, regardless of the status +of the particular user or of the way in which the particular user +actually uses, or expects or is expected to use, the product. A product +is a consumer product regardless of whether the product has substantial +commercial, industrial or non-consumer uses, unless such uses represent +the only significant mode of use of the product. + + "Installation Information" for a User Product means any methods, +procedures, authorization keys, or other information required to install +and execute modified versions of a covered work in that User Product from +a modified version of its Corresponding Source. The information must +suffice to ensure that the continued functioning of the modified object +code is in no case prevented or interfered with solely because +modification has been made. + + If you convey an object code work under this section in, or with, or +specifically for use in, a User Product, and the conveying occurs as +part of a transaction in which the right of possession and use of the +User Product is transferred to the recipient in perpetuity or for a +fixed term (regardless of how the transaction is characterized), the +Corresponding Source conveyed under this section must be accompanied +by the Installation Information. But this requirement does not apply +if neither you nor any third party retains the ability to install +modified object code on the User Product (for example, the work has +been installed in ROM). + + The requirement to provide Installation Information does not include a +requirement to continue to provide support service, warranty, or updates +for a work that has been modified or installed by the recipient, or for +the User Product in which it has been modified or installed. Access to a +network may be denied when the modification itself materially and +adversely affects the operation of the network or violates the rules and +protocols for communication across the network. + + Corresponding Source conveyed, and Installation Information provided, +in accord with this section must be in a format that is publicly +documented (and with an implementation available to the public in +source code form), and must require no special password or key for +unpacking, reading or copying. + + 7. Additional Terms. + + "Additional permissions" are terms that supplement the terms of this +License by making exceptions from one or more of its conditions. +Additional permissions that are applicable to the entire Program shall +be treated as though they were included in this License, to the extent +that they are valid under applicable law. If additional permissions +apply only to part of the Program, that part may be used separately +under those permissions, but the entire Program remains governed by +this License without regard to the additional permissions. + + When you convey a copy of a covered work, you may at your option +remove any additional permissions from that copy, or from any part of +it. (Additional permissions may be written to require their own +removal in certain cases when you modify the work.) You may place +additional permissions on material, added by you to a covered work, +for which you have or can give appropriate copyright permission. + + Notwithstanding any other provision of this License, for material you +add to a covered work, you may (if authorized by the copyright holders of +that material) supplement the terms of this License with terms: + + a) Disclaiming warranty or limiting liability differently from the + terms of sections 15 and 16 of this License; or + + b) Requiring preservation of specified reasonable legal notices or + author attributions in that material or in the Appropriate Legal + Notices displayed by works containing it; or + + c) Prohibiting misrepresentation of the origin of that material, or + requiring that modified versions of such material be marked in + reasonable ways as different from the original version; or + + d) Limiting the use for publicity purposes of names of licensors or + authors of the material; or + + e) Declining to grant rights under trademark law for use of some + trade names, trademarks, or service marks; or + + f) Requiring indemnification of licensors and authors of that + material by anyone who conveys the material (or modified versions of + it) with contractual assumptions of liability to the recipient, for + any liability that these contractual assumptions directly impose on + those licensors and authors. + + All other non-permissive additional terms are considered "further +restrictions" within the meaning of section 10. If the Program as you +received it, or any part of it, contains a notice stating that it is +governed by this License along with a term that is a further +restriction, you may remove that term. If a license document contains +a further restriction but permits relicensing or conveying under this +License, you may add to a covered work material governed by the terms +of that license document, provided that the further restriction does +not survive such relicensing or conveying. + + If you add terms to a covered work in accord with this section, you +must place, in the relevant source files, a statement of the +additional terms that apply to those files, or a notice indicating +where to find the applicable terms. + + Additional terms, permissive or non-permissive, may be stated in the +form of a separately written license, or stated as exceptions; +the above requirements apply either way. + + 8. Termination. + + You may not propagate or modify a covered work except as expressly +provided under this License. Any attempt otherwise to propagate or +modify it is void, and will automatically terminate your rights under +this License (including any patent licenses granted under the third +paragraph of section 11). + + However, if you cease all violation of this License, then your +license from a particular copyright holder is reinstated (a) +provisionally, unless and until the copyright holder explicitly and +finally terminates your license, and (b) permanently, if the copyright +holder fails to notify you of the violation by some reasonable means +prior to 60 days after the cessation. + + Moreover, your license from a particular copyright holder is +reinstated permanently if the copyright holder notifies you of the +violation by some reasonable means, this is the first time you have +received notice of violation of this License (for any work) from that +copyright holder, and you cure the violation prior to 30 days after +your receipt of the notice. + + Termination of your rights under this section does not terminate the +licenses of parties who have received copies or rights from you under +this License. If your rights have been terminated and not permanently +reinstated, you do not qualify to receive new licenses for the same +material under section 10. + + 9. Acceptance Not Required for Having Copies. + + You are not required to accept this License in order to receive or +run a copy of the Program. Ancillary propagation of a covered work +occurring solely as a consequence of using peer-to-peer transmission +to receive a copy likewise does not require acceptance. However, +nothing other than this License grants you permission to propagate or +modify any covered work. These actions infringe copyright if you do +not accept this License. Therefore, by modifying or propagating a +covered work, you indicate your acceptance of this License to do so. + + 10. Automatic Licensing of Downstream Recipients. + + Each time you convey a covered work, the recipient automatically +receives a license from the original licensors, to run, modify and +propagate that work, subject to this License. You are not responsible +for enforcing compliance by third parties with this License. + + An "entity transaction" is a transaction transferring control of an +organization, or substantially all assets of one, or subdividing an +organization, or merging organizations. If propagation of a covered +work results from an entity transaction, each party to that +transaction who receives a copy of the work also receives whatever +licenses to the work the party's predecessor in interest had or could +give under the previous paragraph, plus a right to possession of the +Corresponding Source of the work from the predecessor in interest, if +the predecessor has it or can get it with reasonable efforts. + + You may not impose any further restrictions on the exercise of the +rights granted or affirmed under this License. For example, you may +not impose a license fee, royalty, or other charge for exercise of +rights granted under this License, and you may not initiate litigation +(including a cross-claim or counterclaim in a lawsuit) alleging that +any patent claim is infringed by making, using, selling, offering for +sale, or importing the Program or any portion of it. + + 11. Patents. + + A "contributor" is a copyright holder who authorizes use under this +License of the Program or a work on which the Program is based. The +work thus licensed is called the contributor's "contributor version". + + A contributor's "essential patent claims" are all patent claims +owned or controlled by the contributor, whether already acquired or +hereafter acquired, that would be infringed by some manner, permitted +by this License, of making, using, or selling its contributor version, +but do not include claims that would be infringed only as a +consequence of further modification of the contributor version. For +purposes of this definition, "control" includes the right to grant +patent sublicenses in a manner consistent with the requirements of +this License. + + Each contributor grants you a non-exclusive, worldwide, royalty-free +patent license under the contributor's essential patent claims, to +make, use, sell, offer for sale, import and otherwise run, modify and +propagate the contents of its contributor version. + + In the following three paragraphs, a "patent license" is any express +agreement or commitment, however denominated, not to enforce a patent +(such as an express permission to practice a patent or covenant not to +sue for patent infringement). To "grant" such a patent license to a +party means to make such an agreement or commitment not to enforce a +patent against the party. + + If you convey a covered work, knowingly relying on a patent license, +and the Corresponding Source of the work is not available for anyone +to copy, free of charge and under the terms of this License, through a +publicly available network server or other readily accessible means, +then you must either (1) cause the Corresponding Source to be so +available, or (2) arrange to deprive yourself of the benefit of the +patent license for this particular work, or (3) arrange, in a manner +consistent with the requirements of this License, to extend the patent +license to downstream recipients. "Knowingly relying" means you have +actual knowledge that, but for the patent license, your conveying the +covered work in a country, or your recipient's use of the covered work +in a country, would infringe one or more identifiable patents in that +country that you have reason to believe are valid. + + If, pursuant to or in connection with a single transaction or +arrangement, you convey, or propagate by procuring conveyance of, a +covered work, and grant a patent license to some of the parties +receiving the covered work authorizing them to use, propagate, modify +or convey a specific copy of the covered work, then the patent license +you grant is automatically extended to all recipients of the covered +work and works based on it. + + A patent license is "discriminatory" if it does not include within +the scope of its coverage, prohibits the exercise of, or is +conditioned on the non-exercise of one or more of the rights that are +specifically granted under this License. You may not convey a covered +work if you are a party to an arrangement with a third party that is +in the business of distributing software, under which you make payment +to the third party based on the extent of your activity of conveying +the work, and under which the third party grants, to any of the +parties who would receive the covered work from you, a discriminatory +patent license (a) in connection with copies of the covered work +conveyed by you (or copies made from those copies), or (b) primarily +for and in connection with specific products or compilations that +contain the covered work, unless you entered into that arrangement, +or that patent license was granted, prior to 28 March 2007. + + Nothing in this License shall be construed as excluding or limiting +any implied license or other defenses to infringement that may +otherwise be available to you under applicable patent law. + + 12. No Surrender of Others' Freedom. + + If 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 convey a +covered work so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you may +not convey it at all. For example, if you agree to terms that obligate you +to collect a royalty for further conveying from those to whom you convey +the Program, the only way you could satisfy both those terms and this +License would be to refrain entirely from conveying the Program. + + 13. Use with the GNU Affero General Public License. + + Notwithstanding any other provision of this License, you have +permission to link or combine any covered work with a work licensed +under version 3 of the GNU Affero General Public License into a single +combined work, and to convey the resulting work. The terms of this +License will continue to apply to the part which is the covered work, +but the special requirements of the GNU Affero General Public License, +section 13, concerning interaction through a network will apply to the +combination as such. + + 14. Revised Versions of this License. + + The Free Software Foundation may publish revised and/or new versions of +the GNU 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 that a certain numbered version of the GNU General +Public License "or any later version" applies to it, you have the +option of following the terms and conditions either of that numbered +version or of any later version published by the Free Software +Foundation. If the Program does not specify a version number of the +GNU General Public License, you may choose any version ever published +by the Free Software Foundation. + + If the Program specifies that a proxy can decide which future +versions of the GNU General Public License can be used, that proxy's +public statement of acceptance of a version permanently authorizes you +to choose that version for the Program. + + Later license versions may give you additional or different +permissions. However, no additional obligations are imposed on any +author or copyright holder as a result of your choosing to follow a +later version. + + 15. Disclaimer of Warranty. + + 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. + + 16. Limitation of Liability. + + IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS +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. + + 17. Interpretation of Sections 15 and 16. + + If the disclaimer of warranty and limitation of liability provided +above cannot be given local legal effect according to their terms, +reviewing courts shall apply local law that most closely approximates +an absolute waiver of all civil liability in connection with the +Program, unless a warranty or assumption of liability accompanies a +copy of the Program in return for a fee. + + 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 +state 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 3 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, see . + +Also add information on how to contact you by electronic and paper mail. + + If the program does terminal interaction, make it output a short +notice like this when it starts in an interactive mode: + + Copyright (C) + This program 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, your program's commands +might be different; for a GUI interface, you would use an "about box". + + You should also get your employer (if you work as a programmer) or school, +if any, to sign a "copyright disclaimer" for the program, if necessary. +For more information on this, and how to apply and follow the GNU GPL, see +. + + The GNU 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 Lesser General +Public License instead of this License.

The following +more-detailed instructions are generic; see the `README' file for +instructions specific to this package. + + The `configure' shell script attempts to guess correct values for +various system-dependent variables used during compilation. It uses +those values to create a `Makefile' in each directory of the package. +It may also create one or more `.h' files containing system-dependent +definitions. Finally, it creates a shell script `config.status' that +you can run in the future to recreate the current configuration, and a +file `config.log' containing compiler output (useful mainly for +debugging `configure'). + + It can also use an optional file (typically called `config.cache' +and enabled with `--cache-file=config.cache' or simply `-C') that saves +the results of its tests to speed up reconfiguring. Caching is +disabled by default to prevent problems with accidental use of stale +cache files. + + If you need to do unusual things to compile the package, please try +to figure out how `configure' could check whether to do them, and mail +diffs or instructions to the address given in the `README' so they can +be considered for the next release. If you are using the cache, and at +some point `config.cache' contains results you don't want to keep, you +may remove or edit it. + + The file `configure.ac' (or `configure.in') is used to create +`configure' by a program called `autoconf'. You need `configure.ac' if +you want to change it or regenerate `configure' using a newer version +of `autoconf'. + +The simplest way to compile this package is: + + 1. `cd' to the directory containing the package's source code and type + `./configure' to configure the package for your system. + + Running `configure' might take a while. While running, it prints + some messages telling which features it is checking for. + + 2. Type `make' to compile the package. + + 3. Optionally, type `make check' to run any self-tests that come with + the package. + + 4. Type `make install' to install the programs and any data files and + documentation. + + 5. You can remove the program binaries and object files from the + source code directory by typing `make clean'. To also remove the + files that `configure' created (so you can compile the package for + a different kind of computer), type `make distclean'. There is + also a `make maintainer-clean' target, but that is intended mainly + for the package's developers. If you use it, you may have to get + all sorts of other programs in order to regenerate files that came + with the distribution. + + 6. Often, you can also type `make uninstall' to remove the installed + files again. + +Compilers and Options +===================== + + Some systems require unusual options for compilation or linking that +the `configure' script does not know about. Run `./configure --help' +for details on some of the pertinent environment variables. + + You can give `configure' initial values for configuration parameters +by setting variables in the command line or in the environment. Here +is an example: + + ./configure CC=c99 CFLAGS=-g LIBS=-lposix + + *Note Defining Variables::, for more details. + +Compiling For Multiple Architectures +==================================== + + You can compile the package for more than one kind of computer at the +same time, by placing the object files for each architecture in their +own directory. To do this, you can use GNU `make'. `cd' to the +directory where you want the object files and executables to go and run +the `configure' script. `configure' automatically checks for the +source code in the directory that `configure' is in and in `..'. + + With a non-GNU `make', it is safer to compile the package for one +architecture at a time in the source code directory. After you have +installed the package for one architecture, use `make distclean' before +reconfiguring for another architecture. + + On MacOS X 10.5 and later systems, you can create libraries and +executables that work on multiple system types--known as "fat" or +"universal" binaries--by specifying multiple `-arch' options to the +compiler but only a single `-arch' option to the preprocessor. Like +this: + + ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ + CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ + CPP="gcc -E" CXXCPP="g++ -E" + + This is not guaranteed to produce working output in all cases, you +may have to build one architecture at a time and combine the results +using the `lipo' tool if you have problems. + +Installation Names +================== + + By default, `make install' installs the package's commands under +`/usr/local/bin', include files under `/usr/local/include', etc. You +can specify an installation prefix other than `/usr/local' by giving +`configure' the option `--prefix=PREFIX'. + + You can specify separate installation prefixes for +architecture-specific files and architecture-independent files. If you +pass the option `--exec-prefix=PREFIX' to `configure', the package uses +PREFIX as the prefix for installing programs and libraries. +Documentation and other data files still use the regular prefix. + + In addition, if you use an unusual directory layout you can give +options like `--bindir=DIR' to specify different values for particular +kinds of files. Run `configure --help' for a list of the directories +you can set and what kinds of files go in them. + + If the package supports it, you can cause programs to be installed +with an extra prefix or suffix on their names by giving `configure' the +option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. + +Optional Features +================= + + Some packages pay attention to `--enable-FEATURE' options to +`configure', where FEATURE indicates an optional part of the package. +They may also pay attention to `--with-PACKAGE' options, where PACKAGE +is something like `gnu-as' or `x' (for the X Window System). The +`README' should mention any `--enable-' and `--with-' options that the +package recognizes. + + For packages that use the X Window System, `configure' can usually +find the X include and library files automatically, but if it doesn't, +you can use the `configure' options `--x-includes=DIR' and +`--x-libraries=DIR' to specify their locations. + +Particular systems +================== + + On HP-UX, the default C compiler is not ANSI C compatible. If GNU +CC is not installed, it is recommended to use the following options in +order to use an ANSI C compiler: + + ./configure CC="cc -Ae" + +and if that doesn't work, install pre-built binaries of GCC for HP-UX. + + On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot +parse its `' header file. The option `-nodtk' can be used as +a workaround. If GNU CC is not installed, it is therefore recommended +to try + + ./configure CC="cc" + +and if that doesn't work, try + + ./configure CC="cc -nodtk" + +Specifying the System Type +========================== + + There may be some features `configure' cannot figure out +automatically, but needs to determine by the type of machine the package +will run on. Usually, assuming the package is built to be run on the +_same_ architectures, `configure' can figure that out, but if it prints +a message saying it cannot guess the machine type, give it the +`--build=TYPE' option. TYPE can either be a short name for the system +type, such as `sun4', or a canonical name which has the form: + + CPU-COMPANY-SYSTEM + +where SYSTEM can have one of these forms: + + OS KERNEL-OS + + See the file `config.sub' for the possible values of each field. If +`config.sub' isn't included in this package, then this package doesn't +need to know the machine type. + + If you are _building_ compiler tools for cross-compiling, you should +use the option `--target=TYPE' to select the type of system they will +produce code for. + + If you want to _use_ a cross compiler, that generates code for a +platform different from the build platform, you should specify the +"host" platform (i.e., that on which the generated programs will +eventually be run) with `--host=TYPE'. + +Sharing Defaults +================ + + If you want to set default values for `configure' scripts to share, +you can create a site shell script called `config.site' that gives +default values for variables like `CC', `cache_file', and `prefix'. +`configure' looks for `PREFIX/share/config.site' if it exists, then +`PREFIX/etc/config.site' if it exists. Or, you can set the +`CONFIG_SITE' environment variable to the location of the site script. +A warning: not all `configure' scripts look for a site script. + +Defining Variables +================== + + Variables not defined in a site shell script can be set in the +environment passed to `configure'. However, some packages may run +configure again during the build, and the customized values of these +variables may be lost. In order to avoid this problem, you should set +them in the `configure' command line, using `VAR=value'. For example: + + ./configure CC=/usr/local2/bin/gcc + +causes the specified `gcc' to be used as the C compiler (unless it is +overridden in the site shell script). + +Unfortunately, this technique does not work for `CONFIG_SHELL' due to +an Autoconf bug. Until the bug is fixed you can use this workaround: + + CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash + +`configure' Invocation +====================== + + `configure' recognizes the following options to control how it +operates. + +`--help' +`-h' + Print a summary of all of the options to `configure', and exit. + +`--help=short' +`--help=recursive' + Print a summary of the options unique to this package's + `configure', and exit. The `short' variant lists options used + only in the top level, while the `recursive' variant lists options + also present in any nested packages. + +`--version' +`-V' + Print the version of Autoconf used to generate the `configure' + script, and exit. + +`--cache-file=FILE' + Enable the cache: use and save the results of the tests in FILE, + traditionally `config.cache'. FILE defaults to `/dev/null' to + disable caching. + +`--config-cache' +`-C' + Alias for `--cache-file=config.cache'. + +`--quiet' +`--silent' +`-q' + Do not print messages saying which checks are being made. To + suppress all normal output, redirect it to `/dev/null' (any error + messages will still be shown). + +`--srcdir=DIR' + Look for the package's source code in directory DIR. Usually + `configure' can determine that directory automatically. + +`--prefix=DIR' + Use DIR as the installation prefix. *Note Installation Names:: + for more details, including other options available for fine-tuning + the installation locations. + +`--no-create' +`-n' + Run the configure checks, but stop before creating any output + files. + +`configure' also accepts some other, not widely useful, options. Run +`configure --help' for more details. + diff -Naurp open-iscsi-2.0-872-rc4-bnx2i/iscsiuio/install-sh open-iscsi-2.0-872-rc4-bnx2i.build/iscsiuio/install-sh --- open-iscsi-2.0-872-rc4-bnx2i/iscsiuio/install-sh 1969-12-31 18:00:00.000000000 -0600 +++ open-iscsi-2.0-872-rc4-bnx2i.build/iscsiuio/install-sh 2011-08-03 20:01:01.000000000 -0500 @@ -0,0 +1,519 @@ +#!/bin/sh +# install - install a program, script, or datafile + +scriptversion=2006-12-25.00 + +# This originates from X11R5 (mit/util/scripts/install.sh), which was +# later released in X11R6 (xc/config/util/install.sh) with the +# following copyright and license. +# +# Copyright (C) 1994 X Consortium +# +# Permission is hereby granted, free of charge, to any person obtaining a copy +# of this software and associated documentation files (the "Software"), to +# deal in the Software without restriction, including without limitation the +# rights to use, copy, modify, merge, publish, distribute, sublicense, and/or +# sell copies of the Software, and to permit persons to whom the Software is +# furnished to do so, subject to the following conditions: +# +# The above copyright notice and this permission notice shall be included in +# all copies or substantial portions of the Software. +# +# THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR +# IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, +# FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

The IPv6 address used for the connection will be matched against +the DHCPv6/static IPv6 address, the RA (router advertise) address, and the +assigned link local address. + +VLAN support: + +VLAN support is only supported when using static IP addresses. +Also, currently only 1 VLAN is supported per physical network interface. +Either non-VLAN offloaded traffic is allowed or VLAN offloaded traffic +is allowed. The current implementation does not support both at the +same time. + +Currently there is no explicit VLAN attributes in the iface file. +To configure the VLAN offload, the iface.hwaddress attribute or +physical net_ifacename (without the VLAN identifier) must be used +to specify the HBA device. For the proper CNIC routing, the +corresponding L2 interface which has the associated VLAN interface must +be on the same subnet. + +The following attributes need to be filled when offloading via the +VLAN interface: + + iface.iscsi_ifacename = + iface.hwaddress = XX:XX:XX:XX:XX:XX + iface.ipaddress = XX.XX.XX.XX + iface.transport_name = bnx2i + +Setting IP address: + +On RHEL5.4, RHEL5.5, RHEL5.6, RHEL6.0, SLES11SP1 distributions, +discovery login is done over the Linux TCP/IP stack and L2 network +interface. The ethx interface corresponding to the HBA must +therefore be in the same IP subnet in order to reach the iSCSI +target during discovery. However, the HBA's IP address should not +be the same as the L2 ethx's IP address. + +Starting with RHEL6.1 and all other newer distributions, discovery +using SendTargets is done over the HBA interface, so there is no +need for the HBA and L2 network to be on the same subnet. However, +if VLAN is used on the HBA, they still have to be on the same subnet +as described above. + + +Setting Netmask and Gateway addresses: + +With the current limitations of the iface file, there are no entries +to allow the user to enter neither a netmask or gateway IP address. + +The only way to explicitly configure these options is to use DHCP +addressing. Then the netmask/gateway are set on the DHCP server. +These settings are then sent to uIP via the DHCPOFFERs. + +If the netmask is not defined then the netmask are automatically +generated depending on the destination IP address. + +Debugging: +======================================= + +The iscsiuio daemon will output messages to the log file, +'/var/log/iscsiuio.log'. These messages can be used to help debug any issues. + +A sample banner message: + +INFO [Mon Jun 20 11:23:14 2011]Started iSCSI uio stack: Ver 0.7.0.6 +INFO [Mon Jun 20 11:23:14 2011]Build date: Mon Jun 20 11:22:05 PDT 2011 +INFO [Mon Jun 20 11:23:14 2011]Debug mode enabled + +When debugging issues like the iscsid, the iscsiuio daemon can be run +in the foreground and the maximum debugging level should be used. + +To place the daemon in foreground mode please pass the parameter '-f' +To run the daemon in debug mode please pass the parameter '-d ' + +where the following debug levels are defined: + +DEBUG 4 - Print all messages +INFO 3 - Print messages needed to follow the uIP code (default) +WARN 2 - Print warning messages +ERROR 1 - Only print critical errors + +Note: The messages to the log file are not flushed unless debugging is enabled. + +Note: If the daemon iscsiuio is running, one will not be able to + trample over the exisiting binary.

Problem: Cont00054996 - Multi-session, multi-protocol mtu stress + does not recover all sessions + Cause: A segfault was observed during the load/unload module. The + problem was caused by an illegal dereference of a pointer + when IPv6 couldn't find the longest match address from + the ARP (Neighbor) table. + Change: Fixed the dereferencing error + + 3. Problem: Cont00054900 - Linux uIP - Please add ability to connect + to routed target with static iface IPv6 + Cause: Static IPv6 never runs the IPv6 NDP router sol/adv engine. + Change: IPv6 NDP router sol/adv has now been added to static IPv6 + operation. + + 4. Problem: Cont00054996 - Multi-session, multi-protocol mtu stress + does not recover all sessions + Cause: Segfaults were observed caused by the accessing of the IPv6 + NDP structure while the nic is undergoing a reset either + due to a DHCPv4 request from iscsid or the handling of + if_down due to the NL handler from CNIC. + Change: The fix involves the following: + - Fixed the handling of staggered IPv4/v6 DHCP/static requests + - Fixed memory leak due to reallocation of IPv4 and IPv6 + DHCP structs + - Fixed the pthread join stuck problem in the handling + of the if_down NL message + + 5. Problem: Cont00054810 - Linux NMI - bnx2x_init_hw_common:PXP2 CFG + failed running iSCSI MTU stress test + Cause: This only happens in DHCPv4 mode. The problem was caused + by contention between the elongated window of performing + DHCP in the enable_nic thread while receiving the asynchronous + if_down NL message (from the MTU change event) from the + CNIC NL thread. The problem occurs when the enable_nic + thread tries to call bnx2x_open while the other thread + calls the bnx2x_close routine. + Change: Fixed mutex lock bugs for the enable_nic thread. Also + extended the nic_disable timeout to 10s to compensate for + the DHCP operation. + + 6. Problem: Cont00054818 - RH6.0 - Unable to logout of iSCSI session + after running PQA baseline scripts + Cause: This was caused by the call to cancel the enable_nic + thread when disabling the nic but failed to unlock the + nic mutex that the enable_nic thread held. + Change: Wake up the enable_nic thread and wait for it to complete + instead of canceling it in the nic_disable path. + + 7. Problem: Cont00054725 - Previous static HBA IP will be used after + a new static HBA IP has been created + Cause: There was an assumption in the code where if the same + nic_iface structure was found based on the nic/vlan pair, + the specified IP address would not be used. Instead, it + will continue to use the previous defined IP address. + Change: The previous IP address will now be compared against the + the specified IP address before finishing the parce + iface request from iscsid. If different, the current + nic will be disabled and then re-enabled with the newly + specified IP address. + + 8. Problem: Cont00054571 - Unable to connect to routed ipv6 target + with RA address and iface DHCPv6 + Cause: The default router address was not being employed for + the IPv6 neighbor negotiation. Additionally, the return + address of our neighbor advertisement was incorrect as + it should use the best matched src address instead. + Change: Fixed both the IPv6 neighbor solicitation and advertisement + transmission and handling. + + 9. Problem: Cont00054510 - fails to login to 32 session with blanket + login IPv6 + Cause: A bug was introduced in uIP 0.6.4.6 where the NIC_RUNNING + flag might not be set when entering the main loop under + certain situations depending on the nic bring up. + Change: A new NIC_STARTED_RUNNING flag is now defined to fix CQ53511. + + 10. Problem: Cont00053807 - RA and link local are unable to connect if DHCPv6 + fails + Cause: The host link local address was not being searched as one of + the host address to be replied to CNIC for the connect request. + Change: The path reply now includes the search of host link local + address as well. + + 11. Problem: Cont00054236 - iSCSI service must be restarted before an IPv6 + connection can be made to the Equalogic target + Cause: The problem was intermittent as it depends on which IPv6 address + the target was redirecting to. Since uIP was only extracting + the target's IPv6 address + MAC from the target's neighbor + advertisement packet itself and not from the ICMPv6 option, so + the wrong or no MAC address will get send down to CNIC for the + connection establishment; hence the no connect. + Change: Added the updating of the neighbor discovery table to also use + the Target IPv6 address + MAC specified in the incoming neighbor + advertisement's ICMPv6 option field. + + 12. Problem: Cont00053255 - bnx2x panic dump logging into multiple + discovered IPv6 nodes (Equalogic IPv6 target) + Cause: The bnx2x panic was fixed in the 10g fw 6.4.29. + A IPv6 connectivity issue was then found and led to different + kernel/uIP crashes. This was caused by the same IPv6 + connectivity problem mentioned above. + Change: Same as above + + 13. Problem: Cont00053728 - Sessions never recover after doing initiator-side + cable pull test with IPv6 traffic against Equalogic targets + Cause: It was discovered that the Equalogic would send out periodic + neighbor solicitation to maintain the connection to the + initiator. Since uIP was responding with the assigned IPv6 + link local address in the neighbor advertisement + unconditionally, the target was observed to stop transmitting on + the connection specified. + Change: The neighbor advertisement generated will now use the dst IPv6 + address from the input neighbor solicitation packet instead of + the assigned IPv6 link local address for both the packet and the + ICMPv6 source IPv6 address. + + 14. Problem: Compile error under 32-bit OS + Cause: A bug was introduced in the previous release 0.6.4.6 which + caused a compilation error in 32-bit OS (64-bit compiles + fine) + Change: Fixed the bug + + 15. Problem: Cont00053807 - RA and Link local are unable to connect if dhcpv6 + fails + Cause: There was a bug in the nl reply where the RA address will never + be sent back to CNIC for the connection request + Change: The best matched address to the dst will now be sent back to + CNIC in the path rsp. + + Enhancements + ------------ + 1. Change: Updated README to remove the 57713/E references + + 2. Change: Allow the ICMP option field in the IPv6 Neighbor Advertisement + response to be included without discrimination. This fixes + an issue connecting against the EQL via RA for DHCPv6. + + 3. Change: Updated README for the IPv6 operation, VLAN, and discovery. + + +uIP v0.7.0.1 (Mar. 29, 2011) +======================================================= + Fixes + ----- + 1. Problem: Cont00053511 - bnx2x panic dump during ifup/down stress with + iSCSI traffic + Cause: The panic dump was resolved by the driver's rq dbell size fix. + After that, uIP crashed due to the asynchronous if_down event + that took the chip resources away while the nic thread is still + continuing to try to send DHCP request. + Change: Added synchronization between the two threads so proper clean up + of the threads can occur. + + Enhancements + ------------ + 1. Change: Added support for E3 (57800, 57810, and 57840) + + +uIP v0.6.4.5 (Mar. 23, 2011) +======================================================= + Enhancements + ------------ + 1. Change: Optimized the double VLAN fix of CQ53870 to match + what will be submitted for RHELS5.7 and RHELS6.1 inbox + + +uIP v0.6.4.4 (Mar. 17, 2011) +======================================================= + Fixes + ----- + 1. Problem: Cont00053870 - Unable to login to iSCSI target via offload + through a Nexus 5020 switch with DCBx enabled + Cause: Double VLAN tagging was observed due to DCBx enabled. + The chip actually adds a VLAN tag if the txbd does not have + VLAN tag enabled under the DCBx environment for PRI setting. + Since uIP does not make use of hw assisted VLAN tagging, + 2 VLAN tag was observed in the data stream. + Change: Enabled hw assisted VLAN tagging in uIP for both 1g and 10g. + + 2. Problem: Cont00053792 - maxconnections intermittently fail and + recover using iface DHCPv4 + Cause: The DHCPv4 engine erroneously keeps on requesting for a + new lease which tremendously hamper normal path_req + operation. The problem is that the lease time parameter + has overflowed when converted to ticks count. + Change: Expanded the lease timer ticks count parameter from 16 to + 32 bits. + + 3. Problem: Cont00053807 - RA and link local are unable to connect if + DHCPv6 fails + Cause: The DHCPv6 engine does not have the failover to use RA + mechanism + Change: Expanded to use best match address instead regardless of + DHCPv6 success or not, or using static v6. + + Enhancements + ------------ + 1. Change: Cont00051823 - Added man page for brcm_iscsiuio + + +uIP v0.6.4.3 (Mar. 15, 2011) +======================================================= + Fixes + ----- + 1. Problem: Cont00053719 - intermittent logging into targets that + are not in the same subnet as defined in the iface + Cause: The default route was used erroneously due to a miscompare + Change: Fixed this comparison so if the requested dst is not in + in the same subnet, uIP would not even ARP out. + + 2. Problem: Cont00053580 - Unable to do iSCSI boot into Linux OS using + 57710 adapters + Cause: The E1 iro USTORM_RX_PROD_OFFSET doesn't match the t6.4 fw + Change: This is now fixed + + +uIP v0.6.4.2 (Feb. 24, 2011) +======================================================= + Fixes + ----- + 1. Problem: Cont00050343 - HBA does not follow RFC2131 spec for IPv4 + DHCP lease expiration + Cause: The dhcp engine did not have this feature implemented + Change: Added lease time tracking and renewal + + 2. Problem: Cont00050801 - Unable to connect to target after switching + between DHCPv4 to static v4 + Cause: The configuration flags got corrupted when switching between + dhcp and static or vice versa. + Change: Fixed the flag handling. Also needed to zero out the static + ip address in the host memory when switching to dhcp. + Otherwise, the static ip address will get used mistakenly. + + Enhancements + ------------ + 1. Change: Cont00051936 - Added IPv6 NDP and DHCPv6 support. + + +uIP v0.6.4.1 (Jan. 27, 2011) +======================================================= + Fixes + ----- + 1. Problem: Cont00049766 - segfault seen while stopping iscsi service + Cause: The logger output routine was accessing the log resource + while another thread calls fini_logger to free the same + resources + Change: Added pthread mutex lock to the logger routine to exclude + the initializer, user, and finisher + + Enhancements + ------------ + 1. Change: Added new t6.4 HSI and 57713 support. + + +uIP v0.6.2.13 (Jan. 04, 2011) +======================================================= + Fixes + ----- + 1. Problem: Cont00049665 - iscsiboot:linux failed to boot into iscsi + boot image in offload path after 5 iterations + Cause: The hw consumer index for the uIP ring got out of sync + with the producer index. This has led to the xmit mutex + lock be held forever so subsequent ARP requests will not + get transmitted to the wire + Change: Added this out of sync detection and rescue the xmit mutex + lock + +uIP v0.6.2.12 (Dec. 21, 2010) +======================================================= + Fixes + ----- + 1. Problem: Cont00051820 - Session fails to reconnect after gateway + fallback + Cause: Under the HSRP test scenario, it was found that an ARP + request from the SUT is required in order for the HSRP + router to begin sending packets downstream to the SUT. + The default ARP age was originally set to 20 minutes + before a new ARP request will get sent, + Change: Changed the ARP age default to Linux default at 5 minutes + +uIP v0.6.2.11 (Dec. 17, 2010) +======================================================= + Fixes + ----- + 1. Problem: For IPv4, the gateway route was not being utilized + when the subnet mask given or calculated does not + match. This resulted in many unwanted connection + attempts. + Cause: A bug was found in the default gateway calculation + logic which prevented the gateway address from being + used. + Change: Fixed the default gateway logic + + 2. Problem: For IPv6, there are scenarios where it won't connect + Cause: The IPv6 subnet mask as extracted from the CIDR + format might contain garbage data. This garbage data + was then used as part of the subnet mask which would + prevent the correct address mask. + Change: Fixed the subnet mask + +uIP v0.6.2.10 (Dec. 15, 2010) +======================================================= + Fixes + ----- + 1. Problem: IPv6 does not connect for non-CIDR iface.ipaddress + specification + Cause: A bug where all ones was used as the IPv6 netmask + instead of all zeroes. This prevented all IPv6 + path requests from being honored + Change: Fixed the subnet mask used + +uIP v0.6.2.9 (Dec. 14, 2010) +======================================================= + Enhancements + ------------ + 1. Change: Added IP address CIDR notation support for the + iface.ipaddress field in the iface file. + This will allow subnet mask to be defined and used. + +uIP v0.6.2.8 (Dec. 9, 2010) +======================================================= + Fixes + ----- + 1. Problem: ipv6 + ifup/down fails to reconnect + + Cause: There were 2 problems found: + - the xmit_mutex lock was being held indefinitely + - the nl_process_if_down flag for 10g doorbell ringing + did not get reinitialized + + Change: Fixed the xmit_mutex deadlock via trylock + Added nl_process_if_down initialization in the IF_DOWN + process + + 2. Problem: Added fix for the NPAR disabled for 57712 + + Cause: The mac address was not handled correctly + + Change: Fixed the mac address handling. Also requires corresponding + kernel component for the complete fix + +uIP v0.6.2.7 (Dec. 7, 2010) +======================================================= + Enhancements + ------------ + 1. Change: Use the gateway address from the DHCP server the + destination IP address is not in the current subnet. + +uIP v0.6.2.6 (Nov. 16, 2010) +======================================================= + Fixes + ----- + 1. Problem: Warning message seen in the kernel logs, + "uio uio2: uevent: unsupported action string" + + Cause: The improper string was echo'ed into the UIO trigger + field. With an improper string, this message would + appear in the kernel logs. + + Change: uIP will now write the string "online" to the UIO + trigger field. This is the string expected by the + Linux kernel base driver. + + 2. Problem: uIP would segfault during a heavily login/logout + iSCSI subsystem reset senario + + Cause: A double free occurred in the logging portion of the + uIP code, but this was root cause to a double free when + manipulating the NetLink buffers. + + Change: Properly look at the return code from the routine which + will read NetLink messages. Also only free buffers + if they are allocated. + + Enhancements + ------------ + 1. Change: Add ability to print kernel version and machine + architecture to further help debug problems. + + 2. Change: Apply the netmask from DHCP if provided. + +uIP v0.6.2.5 (Nov. 10, 2010) +======================================================= + Fixes + ----- + 1. Problem: iscsid would try to conenct with unintended iSCSI + targets + + Cause: uIP would blindly return the iSCSI target MAC address + regardless if the iSCSI target is reachable via the + given port. + + Change: uIP will try to filter the requests coming from CNIC + by automatically generating a network mask based off + the configured IP addressed. Then this netmask is + masked with the destination IP address. If there is + a match, then the path_req is allowed through. + + 2. Problem: Problems reconnecting back to the target when running + MTU stress tests. + + Cause: cnic/bnx2i and uIP could possibly get out of sync when + an if_down message is sent. + + Change: uIP will now immediately react to the if_down message, + and flush all the path req's and then to process to + if_close. + + Enhancements + ------------ + 1. Change: Fix compile warnings for src/unix/nic_nl.c, + and src/unix/main.c + +uIP v0.6.2.4 (Nov. 4, 2010) +======================================================= + Fixes + ----- + 1. Problem: iSCSI HBA: brcm_iscsiuio segfault during ifdown + with many active sessions + + Cause: uIP will segfault when traversing the error path when + an iSCSI connection is starting but the sysfs entries + have not been created yet. + + Change: Use the errno value rather then the one from the file + descriptor because the file descriptor will be NULL and + the NULL dereference will cause a segfault. + + Enhancements + ------------ + 1. Change: Added initial changes for iSCSI multi-function support for + 10G NIC's. + 2. Change: Add more detailed messages for error pathes in nic_utils + +uIP v0.6.2.3 (October 28, 2010) +======================================================= + Enhancements + ------------ + 1. Change: Add support for bnx2x-1.62.x drivers + +uIP v0.6.2.2 (October 18, 2010) +======================================================= + Enhancements + ------------ + 1. Change: Only allow iSCSI connections with known bnx2x HSI's. + +uIP v0.6.2.1 (October 7, 2010) +======================================================= + Fixes + ----- + 1. Problem: After multiple MTU changes, the ethtool IOCTL used to + determine the bnx2x driver version fails and eventually + iSCSI connections would not reconnect. + + Cause: The socket file descriptor used during the ethtool IOCTL + call was never closed and leaked. + + Change: On the error path when calling the ethtool IOCTL, the + file descriptor is now properly closed. + +uIP v0.5.39 (September 15, 2010) +======================================================= + Fixes + ----- + 1. Problem: Could not offload IPv4 VLAN connection when the target tries + to ARP the iSCSI initiator + + Cause: In the ARP reply, the ether field was incorrect. + + Change: Properly set the ether field to 802.1Q type (0x8100) + +uIP v0.5.38 (September 14, 2010) +======================================================= + Fixes + ----- + 1. Problem: uIP would cause a panic dump when the NIC was going down + + Cause: uIP and CNIC where not synchonized on NIC state + + Change: Check if the RX BD's which are zero'ed by CNIC when the + NIC is going down. If the BD addresses are zero, then + uIP will drop the TX packets. + +uIP v0.5.37 (August 21, 2010) +======================================================= + Fixes + ----- + 1. Problem: uIP would segfault on ifup/ifdown stress test when using + DHCP to determine local IP address. + + Cause: The uIP would use a NULL buffer during data transmission. + + Change: Drop packets when there are no buffer avaliable. + +uIP v0.5.36 (August 21, 2010) +======================================================= + Fixes + ----- + 1. Problem: iSCSI boot would not completely login after the pivot + root operation. + + Cause: The uIP would not properly start the NIC interface. + + Change: uIP should only check the NIC state to determine whether + to start the NIC thread or not. + + 2. Problem: uIP would segfault during if'up if'down testing. + + Cause: The uIP would improperly start 2 NIC threads for the + same NIC interface. + + Change: uIP should properly lock the NIC list when disabling/removing + the NIC threads. + + +uIP v0.5.35 (August 20, 2010) +======================================================= + Fixes + ----- + 1. Problem: Sessions would hang with ethtool self-test + + Cause: The uIP would hang because the socket layer was stuck + because there is much contention for that socket. This + would hang the CNIC thread. + + Change: Remove any IOCTL calls in uIP which may colide with + the ethtool self test. The driver version is only + capture during uIP initialization. + + 2. Problem: There were session recovery issue when using DHCP + if up/down tests. + + Cause: The uIP would hang because the DHCP requests would + timeout if the network interface is downed which would + hang all the other uIP threads. + + Change: Ensure that the DHCP state machine had exit points + if the network interface was down'ed. + + +uIP v0.5.34 (August 18, 2010) +======================================================= + Fixes + ----- + 1. Problem: Sessions would not recover with ethtool self-test + + Cause: The uIP would hang because either the NetLink buffer is + full or that any socket operations used to manipulate + multicast addresses would block. + + Change: Ensure that the socket used for multicast addressing is + set to nonblocking. Drain the NetLink buffer without + using the eventing, but with a more aggressive poll routine. + + 2. Problem: Sessions would not recover with L2 driver load/unload on + RHEL 6.0 SS9 + + Cause: The uIP would close the NIC thread too early and would + deadlock on cloing the NIC thread. + + Change: Ensure that the NIC thread is canceled/closed only in one + location, in the NIC remove routine. + + +uIP v0.5.33 (August 17, 2010) +======================================================= + Fixes + ----- + 1. Problem: Error message seen from the uIP stack for valid packets. + + Cause: The uIP was incorrectly marking logging messages for valid + packets as errors because it didn't know how to parase them. + + Change: Changed the following from error to debug message + ipv6: invalid version + ipv4: invalid version or header length. + icmpv6: unknown ICMP message. + ip: neither tcp nor icmp + Changed the following from error to warn message + udp: bad checksum + tcp: bad checksum + tcp: got reset, aborting connection. + + 2. Problem: After multiple iterations the loading and unloading of + the Broadcom Linux drivers with active connections + would not cause the sessions to recover on RHEL 6.0 + snapshot 9. + + Cause: There was a deadlock in the nic mutex + + Change: Lock ordering for the nic mutex and nic list mutex must + be inforced. + + 3. Problem: After multiple iterations of running the ethtool selftest + the Broadcom Linux drivers with active connections + would not cause the sessions to recover on RHEL 5.5. + + Cause: The Netlink buffer between uIP and CNIC would get full. + + Change: Poll more regularly for packets in the Netlink buffer + from 4 times a second to 100 times a 1 second. + Drain packets during the PATH_REQ packet pull. + + +uIP v0.5.32 (August 14, 2010) +======================================================= + Fixes + ----- + 1. Problem: Error message 'nic eth0: Didn't find type 0xaa bb' seen. + + Cause: Valid non-DIX Ethernet packets as being passed to the + uIP. uIP will drop these packets but should be logged + correctly. + + Change: These packets are valid, and should only be logged for + debugging purposes. + + 2. Problem: Error message 'Dropped previous transmitted packet' seen. + + Cause: The TX ring is full, and here uIP is trying to transmit a + packet which will be dropped. This is a valid state but + the log message is marked incorrectly + + Change: These messages are not warnings and should be logging when + debugging is enabled. + + 3. Problem: Error message: "iscsi_ipc eth0 Transport name is not + equal expected: got: bnx2i" seen. + + Cause: The iface_rec structure is different between iscsid version. + For RHEL 5.5, iscsid is versioned 871, for RHEL 6.0 is + versioned 872. + + Change: Allow uIP to compile against a different version of iscsid. + + +uIP v0.5.31 (August 12, 2010) +======================================================= + Fixes + ----- + 1. Problem: Softlock would occur showing that the NetLink table + lock was taken but never released. + + Cause: NetLink socket buffer would fill with constant PATH_REQ + messages preventing PATH_REQ response from libiscsi + + Change: Now uIP will drain the NetLink buffer while looking for + a response. + + Enhancements + ------------ + 1. Change: Add documentation for VLAN configuration and restrictions. + + +uIP v0.5.30 (August 6, 2010) +======================================================= + Fixes + ----- + 1. Problem: iscsid thread will stall if closing the uio files nodes + is stuck + + Cause: uIP would indefinitely block waiting for the mutex shared + by the close routine. + + Change: Now uIP will try and poll a bit for the mutex. If it can't + get this mutex in the iscsid thread then an error is return + rather then hold the thread. + + 2. Problem: IPv6 Unicast Neighbor Adveriserments would have the + ICMPv6 option header specifying a MAC. + + Cause: uIP should use the source IPv6 address to detmine whether + to strip the option header or not and not the target address + in the ICMPv6 field. + + Change: The uIP stack return a unicast IPv6 Neighbor Advertisement + without the ICMPv6 option as a response to unicast + IPv6 Neighbor Solicitations. + + 3. Problem: There would be TCP SYN packets with improper MAC address. + + Cause: A zero'ed MAC address was not passed to CNIC to indicate an + error or if the IP address didn't resolve. + + Change: The uIP stack will now return a zero'ed MAC address if it + can't find any entries. + + +uIP v0.5.29 (August 6, 2010) +======================================================= + Fixes + ----- + 1. Problem: "uip udp: no matching connection found: lport: 35072" + seen numerous times in the brcm_iscsiuio log file + + Cause: This message was incorrectly marked as an error + + Change: These messages are valid log entries especially if the + packet was a broadcast UDP packet not destined for the SUT + I will change the code to mark these logs entries as debug. + + +uIP v0.5.28 (August 5, 2010) +======================================================= + Fixes + ----- + 1. Problem: Can't login into a redirected Equilogic Target + + Cause: The Equilogic Target uses a unicast IPv6 Neighbor + Solicitation to test if the host is up. The uIP stack + would return a Neighbor Advertisement with an unneeded + ICMPv6 option. + + Change: Only have the uIP stack return a unicast IPv6 Neighbor + Advertisement without the ICMPv6 option. + + 2. Problem: With older bnx2/bnx2x/cnic/bnx2i driver combinations + uIP would segfault when these drivers were unloaded. + + Cause: When the older drivers were removed, the underlying uio + instance was removed causing uIP to have a stale file handle. + When uIP finally closes using this stale file handle, either + uIP would segfault, or there would be an error in the + uio_release() path. + + Change: Only have the uIP close if the UIO file node exists. + + +uIP v0.5.27 (July 31, 2010) +======================================================= + Fixes + ----- + 1.

Problem: IPv6 using VLAN's didn't login + + Cause: The uIP code used to determine if the packet was an IPv6 + or not was not working. This VLAN packets for IPv6 were + being mis-interpreted. + + Change: Make the function is_ipv6() VLAN aware + + 3. Problem: Persistant targets was not loggin in during boot + + Cause: If udev was slow and the /dev/uio* were creatly slowly + uIP would fail. + + Change: Poll uIP waiting for /dev/uio* file nodes. + +uIP v0.5.25 (July 27, 2010) +======================================================= + Fixes + ----- + 1. Problem: When using IPv4 DHCP, there are no initial DHCP Discover + packets were not seen on the wire. + + Cause: Packets generated from the app handler from the uIP stack + were not placed on the wire. + + Change: Packets originating from the uIP stack are now always placed + on the wire. + +uIP v0.5.24 (July 25, 2010) +======================================================= + Fixes + ----- + 1. Problem: One would see invalid packet packets flow through the + uIP stack, where the logs would indicate there is a packet + with an invalid length + + Cause: The BD and CQE consumer indexes were not properly incremented + and masked. + + Change: The BD index is now properly masked. The CQE index is not + incremented using the CQE index rather the mistaken BD index. + + Impact: 10G only + + 2. Problem: uIP would segfault during the booting of the machine. + + Cause: uIP was using a NULL data pointer because there was an + incorrect packet passed to the stack. + + Change: Only allow uIP to process data if the packet exists. + + 3. Problem: uIP would stop processing packets + + Cause: The uIP code would not properly drain the CQE ring causing + it to eventually be full + + Change: Consume all the CQE elements even if they are ethernet types + or not. + + Impact: 10G only + + 4. Problem: uIP would stop after if/down of the network interface. + + Cause: uIP was not kick starting the NIC loop thread properly. + + Change: Ensure that the NIC loop thread is started by when iscsid + request that the interface start the offload. Mark the NIC + only if the thread is truly canceled. + + +uIP v0.5.23 (July 20, 2010) +======================================================= + Fixes + ----- + 1.
