+ GNU GENERAL PUBLIC LICENSE
+ Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users. This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it. (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.) You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. You must make sure that they, too, receive or can get the
+source code. And you must show them these terms so they know their
+rights.
+
+ We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary. To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ GNU GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License. The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language. (Hereinafter, translation is included without limitation in
+the term "modification".) Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+ 1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+ 2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) You must cause the modified files to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ b) You must cause any work that you distribute or publish, that in
+ whole or in part contains or is derived from the Program or any
+ part thereof, to be licensed as a whole at no charge to all third
+ parties under the terms of this License.
+
+ c) If the modified program normally reads commands interactively
+ when run, you must cause it, when started running for such
+ interactive use in the most ordinary way, to print or display an
+ announcement including an appropriate copyright notice and a
+ notice that there is no warranty (or else, saying that you provide
+ a warranty) and that users may redistribute the program under
+ these conditions, and telling the user how to view a copy of this
+ License. (Exception: if the Program itself is interactive but
+ does not normally print such an announcement, your work based on
+ the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+ a) Accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of Sections
+ 1 and 2 above on a medium customarily used for software interchange; or,
+
+ b) Accompany it with a written offer, valid for at least three
+ years, to give any third party, for a charge no more than your
+ cost of physically performing source distribution, a complete
+ machine-readable copy of the corresponding source code, to be
+ distributed under the terms of Sections 1 and 2 above on a medium
+ customarily used for software interchange; or,
+
+ c) Accompany it with the information you received as to the offer
+ to distribute corresponding source code. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form with such
+ an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it. For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable. However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+ 5. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Program or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+ 6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+ 7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all. For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded. In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+ 9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation. If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+ 10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission. For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this. Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+ NO WARRANTY
+
+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+ 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+
+ How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>
+
+ This program is free software; you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation; either version 2 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU General Public License for more details.
+
+ You should have received a copy of the GNU General Public License along
+ with this program; if not, write to the Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+ Gnomovision version 69, Copyright (C) year name of author
+ Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary. Here is a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+ `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+ <signature of Ty Coon>, 1 April 1989
+ Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs. If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library. If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.

+ GNU LESSER GENERAL PUBLIC LICENSE
+ Version 2.1, February 1999
+
+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL. It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+ This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it. You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations below.
+
+ When we speak of free software, we are referring to freedom of use,
+not price. Our General Public Licenses are designed to make sure that
+you have the freedom to distribute copies of free software (and charge
+for this service if you wish); that you receive source code or can get
+it if you want it; that you can change the software and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+ To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights. These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+ For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you. You must make sure that they, too, receive or can get the source
+code. If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it. And you must show them these terms so they know their rights.
+
+ We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+ To protect each distributor, we want to make it very clear that
+there is no warranty for the free library. Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+
+ Finally, software patents pose a constant threat to the existence of
+any free program. We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder. Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+ Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License. This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License. We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+ When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library. The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom. The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+ We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License. It also provides other free software developers Less
+of an advantage over competing non-free programs. These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries. However, the Lesser license provides advantages in certain
+special circumstances.
+
+ For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it becomes
+a de-facto standard. To achieve this, non-free programs must be
+allowed to use the library. A more frequent case is that a free
+library does the same job as widely used non-free libraries. In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+ In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software. For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+ Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+ The precise terms and conditions for copying, distribution and
+modification follow. Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library". The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+
+ GNU LESSER GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+ A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+ The "Library", below, refers to any such software library or work
+which has been distributed under these terms. A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language. (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+ "Source code" for a work means the preferred form of the work for
+making modifications to it. For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+ Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it). Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+
+ 1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+ You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+ 2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) The modified work must itself be a software library.
+
+ b) You must cause the files modified to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ c) You must cause the whole of the work to be licensed at no
+ charge to all third parties under the terms of this License.
+
+ d) If a facility in the modified Library refers to a function or a
+ table of data to be supplied by an application program that uses
+ the facility, other than as an argument passed when the facility
+ is invoked, then you must make a good faith effort to ensure that,
+ in the event an application does not supply such function or
+ table, the facility still operates, and performs whatever part of
+ its purpose remains meaningful.
+
+ (For example, a function in a library to compute square roots has
+ a purpose that is entirely well-defined independent of the
+ application. Therefore, Subsection 2d requires that any
+ application-supplied function or table used by this function must
+ be optional: if the application does not supply it, the square
+ root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library. To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License. (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.) Do not make any other change in
+these notices.
+
+ Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+ This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+ 4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+ If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library". Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+ However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library". The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+ When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library. The
+threshold for this to be true is not precisely defined by law.
+
+ If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work. (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+ Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+ 6. As an exception to the Sections above, you may also combine or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+ You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License. You must supply a copy of this License. If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License. Also, you must do one
+of these things:
+
+ a) Accompany the work with the complete corresponding
+ machine-readable source code for the Library including whatever
+ changes were used in the work (which must be distributed under
+ Sections 1 and 2 above); and, if the work is an executable linked
+ with the Library, with the complete machine-readable "work that
+ uses the Library", as object code and/or source code, so that the
+ user can modify the Library and then relink to produce a modified
+ executable containing the modified Library. (It is understood
+ that the user who changes the contents of definitions files in the
+ Library will not necessarily be able to recompile the application
+ to use the modified definitions.)
+
+ b) Use a suitable shared library mechanism for linking with the
+ Library. A suitable mechanism is one that (1) uses at run time a
+ copy of the library already present on the user's computer system,
+ rather than copying library functions into the executable, and (2)
+ will operate properly with a modified version of the library, if
+ the user installs one, as long as the modified version is
+ interface-compatible with the version that the work was made with.
+
+ c) Accompany the work with a written offer, valid for at
+ least three years, to give the same user the materials
+ specified in Subsection 6a, above, for a charge no more
+ than the cost of performing this distribution.
+
+ d) If distribution of the work is made by offering access to copy
+ from a designated place, offer equivalent access to copy the above
+ specified materials from the same place.
+
+ e) Verify that the user has already received a copy of these
+ materials or that you have already sent this user a copy.
+
+ For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it. However, as a special exception,
+the materials to be distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+ It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system. Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+ 7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+ a) Accompany the combined library with a copy of the same work
+ based on the Library, uncombined with any other library
+ facilities. This must be distributed under the terms of the
+ Sections above.
+
+ b) Give prominent notice with the combined library of the fact
+ that part of it is a work based on the Library, and explaining
+ where to find the accompanying uncombined form of the same work.
+
+ 8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License. Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License. However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+ 9. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Library or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+ 10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
+this License.
+
+ 11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all. For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded. In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+ 13. The Free Software Foundation may publish revised and/or new
+versions of the Lesser 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 Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation. If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+ 14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission. For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this. Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+ NO WARRANTY
+
+ 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "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
+LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+ 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY 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
+LIBRARY (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 LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+
+ How to Apply These Terms to Your New Libraries
+
+ If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change. You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+ To apply these terms, attach the following notices to the library. It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the library's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>
+
+ This library is free software; you can redistribute it and/or
+ modify it under the terms of the GNU Lesser General Public
+ License as published by the Free Software Foundation; either
+ version 2.1 of the License, or (at your option) any later version.
+
+ This library 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
+ Lesser General Public License for more details.
+
+ You should have received a copy of the GNU Lesser General Public
+ License along with this library; if not, write to the Free Software
+ Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+
+Also add information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary. Here is a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the
+ library `Frob' (a library for tweaking knobs) written by James Random Hacker.

+ option was given. Patch by therealneworld@gmail.com
+
+2011-07-06 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Add ->flock() operation to low and high level interfaces. This
+ fixes problems with emulating flock() with POSIX locking.
+ Reported by Sebastian Pipping. As with lock/setlk/getlk most
+ filesystems don't need to implement this, as the kernel takes care
+ of file locking. The only reason to implement locking operations
+ is for network filesystems which want file locking to work between
+ clients.
+
+2011-07-02 Sebastian Pipping <sebastian@pipping.org>
+
+ * Make xmp_utimens of examples "fusexmp" and "fusexmp_fh"
+ not follow symlinks as other layers do that already.
+
+2011-06-02 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Add "remember" option. This works similar to "noforget" except
+ that eventually the node will be allowed to expire from the cache.
+ Patch by therealneworld@gmail.com
+
+2011-05-27 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Check if splice/vmsplice are supported
+
+2011-05-26 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Remove -lrt -ldl from fuse.pc for dynamic linking since
+ libfuse.so is already linked with these libraries. Reported by:
+ Nikolaus Rath
+
+2011-05-20 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Cleaner build output. Patch by Reuben Hawkins
+
+2011-05-19 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Disable splice by default, add "splice_read", "splice_write" and
+ "splice_move" options. Keep the "no_splice_*" variants, which can
+ disable splice even if the filesystem explicitly enables it.
+
+2011-04-15 Max Krasnyansky <maxk@kernel.org>
+ * Added support for "auto_unmount" option which unmounts the
+ filesystem automatically on process exit (or crash).
+
+2011-03-30 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Patches by Laszlo Papp fixing various issues found by the
+ Coverity checker
+
+2011-03-11 Miklos Szeredi <miklos@szeredi.hu>
+
+ * In case of failure to add to /etc/mtab don't umount. Reported
+ by Marc Deslauriers
+
+2011-02-02 Miklos Szeredi <miklos@szeredi.hu>
+
+ * libfuse: In fuse_session_loop_mt() don't pause when exiting the
+ worker threads. The pause() was added in 2.2.1 to prevent
+ segfault on pthread_cancel() on an exited, detached thread. Now
+ worker threads are not detached and pthread_cancel() should work
+ fine even after the thread exited. Reported by Boris Protopopov
+
+2011-01-31 Miklos Szeredi <miklos@szeredi.hu>
+
+ * fusermount: chdir to / before performing mount/umount
+
+ * fusermount: only allow mount and umount if util-linux supports
+ --no-canonicalize
+
+2010-12-16 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Highlevel lib: allow hash tables to shrink
+
+ * Highlevel lib: add slab allocation for node cache. This will
+ allow the memory used by the filesystem to grow and shrink
+ depending on how many inodes are currently cached.
+
+2010-12-13 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Highlevel lib: use dynamically resized hash table for looking up
+ by name and node ID.
+
+2010-12-07 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Allow batching of forget requests. This allows forget requests
+ to be processed faster and doesn't require a modification to fuse
+ filesystems. Reported by Terje Malmedal
+
+ * Add ->forget_multi() operation to the lowlevel API. The
+ filesystem may implement this to process multiple forget requests
+ in one call
+
+ * Fix the ambiguity of ioctl ABI on the kernel/userspace boundary
+ for 32bit vs. 64bit userspace
+
+2010-11-10 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Add new write_buf() method to the highlevel API. Similarly to
+ the lowlevel write_buf() method, this allows implementing zero
+ copy writes.
+
+ * Add a new read_buf() method to the highlevel API. This allows
+ returning a generic buffer from the read method, which in turn
+ allows zero copy reads.
+
+ * In fusexmp_fh implement the ->read_buf() and ->write_buf()
+ methods. Leave the ->read() and ->write() implementations for
+ reference, even though they are not necessary.
+
+2010-11-08 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Fix check for read-only fs in mtab update
+
+ * Open /dev/null for write instead of read for redirecting stdout
+ and stderr
+
+ * If umount(8) supports --fake and --no-canonicalize (util-linux-ng
+ version 2.18 or later), and umount(2) supports the
+ UMOUNT_NOFOLLOW flag (linux kernel version 2.6.35 or later) then,
+ "fusermount -u" will call the umount(2) system call and use
+ "umount --fake ..." to update /etc/mtab
+
+ * Added --disable-legacy-umount option to configure. This
+ disables the runtime checking of umount(8) version. When built
+ with this option then "fusermount -u" will fail if umount(8)
+ doesn't support the --fake and --no-canonicalize options.
+
+ * Fix fuse_buf_copy() if already at the end of the buffers
+
+ * Add new ->write_buf() method to low level interface. This
+ allows passig a generic buffer, either containing a memory buffer
+ or a file descriptor. This allows implementing zero copy writes.
+
+ * Add fuse_session_receive_buf() and fuse_session_process_buf()
+ which may be used in event loop implementations to replace
+ fuse_chan_recv() and fuse_session_process() respectively.
+
+ * Remove unnecessary restoring of current working directory in
+ "fusermount -u"
+
+ * Add ctx->pid to debug output
+
+ * Fix st_nlink value in high level lib if file is unlinked but
+ still open
+
+ * libfuse: add store request. Request data to be stored in the
+ kernel buffers for a given inode.

+ uclibc + libiconv. Patch by Natanael Copa
+
+2010-10-05 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Add missing argument check in ulockmgr.c to prevent calling
+ ulockmgr_server with illegal arguments. This would cause an ever

+ Patch by Markus Ammer
+
+2010-09-28 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Fix ambiguous symbol version for fuse_chan_new.
+ fuse_versionscript included fuse_chan_new in both FUSE_2.4 and
+ FUSE_2.6. Remove the FUSE_2.4, which is invalid.
+
+2010-09-28 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Fix option escaping for fusermount. If the "fsname=" option
+ contained a comma then the option parser in fusermount was
+ confused (Novell bugzilla #641480). Fix by escaping commas when
+ passing them over to fusermount. Reported by Jan Engelhardt
+
+2010-08-27 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Add NetBSD support. Patch from Emmanuel Dreyfus
+
+2010-07-12 Miklos Szeredi <miklos@szeredi.hu>
+
+ * libfuse: add buffer interface. Add a generic buffer interface
+ for use with I/O. Buffer vectors are supplied and each buffer in
+ the vector may be a memory pointer or a file descriptor.
+
+ * The fuse_reply_fd() interface is converted to using buffers.
+
+2010-06-23 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Make the number of max background requests and congestion
+ threshold tunable. New options are "max_background" and
+ "congestion_threshold". Only effective on linux kernel versions
+ 2.6.32 or greater. Patch by Csaba Henk
+
+2010-06-17 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Add fuse_reply_fd() reply function to the low level interface.
+ On linux version 2.6.35 or greater this will use splice() to move
+ data directly from a file descriptor to the fuse device without
+ needing to go though a userspace buffer. With the
+ FUSE_REPLY_FD_MOVE flag the kernel will attempt to move the data
+ directly into the filesystem's cache. On earlier kernels it will
+ fall back to an intermediate buffer. The options
+ "no_splice_write" and "no_splice_move" can be used to disable
+ splicing and moving respectively.
+
+2010-06-15 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Fix out-of-source build. Patch by Jörg Faschingbauer
+
+ * Add a "nopath" option and flag, indicating that path argument

+
+ * Fix compile error on FreeBSD. Patch by Jay Sullivan
+
+2009-12-17 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Use '--no-canonicalize' option of mount(8) (available in
+ util-linux-ng version 2.17 or greater) to avoid calling
+ readling(2) on the newly mounted filesystem before the mount
+ procedure is finished. This has caused a deadlock if "audit" was
+ enabled in the kernel. Also use '--no-canonicalize' for umount to
+ avoid touching the mounted filesystem.

+
+2009-07-16 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Clarify how the protocol version should be negotiated between

+
+ * Add missing pthread link for libulockmgr. Patch by Petr Salinger
+
+2009-07-02 Miklos Szeredi <miklos@szeredi.hu>
+
+ * The context is extended with a 'umask' field. The umask is sent
+ for mknod, mkdir and create requests by linux kernel version
+ 2.6.31 or later, otherwise the umask is set to zero. Also
+ introduce a new feature flag: FUSE_CAP_DONT_MASK. If the kernel
+ supports this feature, then this flag will be set in conn->capable
+ in the ->init() method. If the filesystem sets this flag in in
+ conn->want, then the create modes will not be masked.
+
+ * Add low level interfaces for lookup cache and attribute
+ invalidation. This feature is available in linux kernels 2.6.31
+ or later. Patch by John Muir
+
+ * Kernel interface version is now 7.12
+
+ * fusermount: Do not silently ignore command line arguments.
+ Patch by Sebastian Harl
+
+2009-06-19 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Released 2.8.0-pre3
+
+2009-06-19 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Add fuse_getgroups (high level lib) and fuse_req_getgroups (low
+ level lib) functions to query the supplementary group IDs for the
+ current request. Currently this is implemented on Linux by
+ reading from the /proc filesystem.
+
+2009-06-18 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Add "noforget" option to high level lib to prevent ESTALE errors
+ on NFS exported filesystems. This result in paths being cached
+ forever, resulting in ever growing memory usage. Use with care.
+
+ * Add "no_remote_lock" option to disable remote file locking even
+ if the filesystem implements it. With this option locking
+ primitives (flock, lockf, fcntl(F_SETLK)) will still work, but
+ will ignore remotely locked files.
+
+ * CUSE patches from Tejun Heo:
+
+ * Unrestricted ioctl support left some debris. Clean them up:
+ o No reason to pass around pointer to flags. Pass flags directly.
+ o Clean up comment and prototype parameter names.
+ o fuse_lib_ioctl() didn't reply when get_path() failed. Fix it.
+ o Remove unused variables {in|out}_iov from fuse_lib_ioctl().
+
+ * Add fuse_reply_ioctl_iov()
+
+ * Move fuse_session, fuse_req and fuse_ll definitions to fuse_i.h
+ and make send_reply_iov() and fuse_setup_common() global (also in
+ fuse_i.h). These will be used by CUSE support.
+
+ * Restructure fuse_ll_process()
+
+ * Implement libfuse side of CUSE support. CUSE uses subset of FUSE
+ operations as dir operations don't make sense for CUSE where one
+ instance implements single character device.
+
+ CUSE support comes with its own cuse_lowevel_ops and related
+ initialization and helper functions. Except for initialization, it
+ usage is basically identical to FUSE.
+
+ This patch also adds example/cusexmp.c which can create a character
+ device with name and device number specified on command line. The
+ created device itself is pretty boring. It's a bit bucket supporting
+ read, write and access via ioctl.
+

+
+ * mount.fuse: add "setuid=USER" option which does a "su - USER"
+ for the filesystem
+
+ * fusermount: use "/bin/mount -f" to add entry to /etc/mtab, and
+ "/bin/umount" to remove entry from /etc/mtab. This gets rid of
+ the ugly code dealing with mtab, as well as a possible race

+
+2006-10-13 Miklos Szeredi <miklos@szeredi.hu>
+
+ * kernel: Fix compilation on patched 2.6.18 (fc6) and 2.6.19.
+ Report from David Shaw
+
+ * lib: Fix lost error on renaming a file. Report from David Shaw
+
+ * lib: Fix lost error on hiding open files (renaming to
+ .fuse_hiddenXXXX)
+
+ * kernel: Fix a rare hang on SMP/32bit on heavy filesystem
+ activity. The cause of the bug was that some calls to
+ i_size_write() were not protected by a lock, and hence
+ i_size_seqcount could become corrupted. This caused subsequent
+ calls to i_size_read() to spin forever. This is a long standing
+ bug was probably introduced in version 2.2, and thought to be
+ related to NFS exporting (it's not). It was reported by various
+ people, but Dana Henriksen has finally helped me to track it down,
+ so big thanks to him
+
+ * kernel: Protect against truncation of a swapfile
+
+2006-10-10 Miklos Szeredi <miklos@szeredi.hu>
+
+ * kernel: Check for signature of super_operations->umount_begin().
+ Ubuntu kernel 2.6.17 seems to use the new signature found in
+ 2.6.18. Thanks to Florent Mertens for the report
+
+2006-10-08 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Make sure inode numers wrap around at 2^32. This is needed on
+ dual 64bit/32bit architectures, because 32bit applications using
+ the non-largefile interface would otherwise break (EOVERFLOW error
+ would be returned by the stat() system call family)
+
+ * ulockmgr: handle the case, when a locking operation fails
+ because no more file desctriptors are available in
+ ulockmgr_server. Also work around a Linux kernel bug (known to
+ exist for all Linux kernel versions <= 2.6.18) which may cause
+ sent file descriptors to be lost in the above case
+
+ * ulockmgr: optimize file descriptor use
+
+ * restore needed cpp flags to util/Makefile.am
+
+ * Install udev rules as 99-fuse.rules instead of 60-fuse.rules
+
+ * Minor clean up of udev rules
+
+ * Add a synchronous DESTROY message to kernel interface. This is
+ invoked from umount, when the final instance of the filesystem is
+ released. It is only sent for filesystems mounted with the
+ 'blkdev' option for security reasons.
+
+ * If the DESTROY message is received, call the filesystem's
+ ->destroy() method. In this case it's not called from session
+ destruction as it would be otherwise.
+
+2006-10-01 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Released 2.6.0-rc2
+
+2006-10-01 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Add support for FLUSH+RELEASE operation for FreeBSD. Original
+ patch by Csaba Henk
+
+ * Add init script to insert fuse module and mount the control
+ filesystem. The script is installed as /etc/init.d/fuse and on
+ debian based systems (where update-rc.d is available) symlinks
+ from /etc/rc*.d/ are also installed.
+
+ * Include '#define FUSE_USE_VERSION=XX' into examples so they
+ become more self contained.
+
+2006-09-30 Miklos Szeredi <miklos@szeredi.hu>
+
+ * API changes:
+
+ * Move lock_owner from a separate argument into fuse_file_info
+
+ * Add a flag to fuse_file_info indicating (1) a highlevel lock
+ operation (unlock all) was initiated by a flush, (2) a lowlevel
+ release operation should perform a flush as well.
+
+ * fusermount: revert modprobe change (2006-08-18) since it
+ doesn't work reliably with udev
+
+ * Add support for block device backed filesystems. This mode is
+ selected with the 'blkdev' option, which is privileged.
+
+ * Add support for the bmap (FIBMAP ioctl) operation on block
+ device backed filesystems. This allows swapon and lilo to work on
+ such filesystems.
+
+ * kernel changes:
+
+ * Drop support for kernels earlier than 2.6.9. Kernel module from
+ previous (2.5.x) release can be used with library from this
+ release
+
+ * In fuse_dentry_revalidate() use dget_parent() instead of
+ dereferencing d_parent, since there's no protection against parent
+ changing and going away
+
+ * Protect nlookup from concurrent updates
+
+ * In lookup if a directory alias exists but is unused,
+ then get rid of it, otherwise return -EBUSY.
+
+ * In mkdir if a directory alias exists, return success, but leave
+ dentry negative. In reality this could happen if a remote rename
+ immediately followed the mkdir.
+
+ * Don't BUG in fuse_iget() if multiple retries are needed to get a
+ good inode. This could happen if several lookups are racing for
+ the same inode.
+
+2006-09-29 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Fix compilation on 2.6.9. Report from Troy Ayers
+
+2006-09-27 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Fix Oops in fuse_readpages(). Reported by David Shaw

+
+ * Fix utimens compilation with uClibc. Patch from Jamie Guinan
+
+2006-09-22 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Fixed several compatibility bugs in low level interface.
+ Reported by Ricardo Correia
+
+ * Add workaround for ARM caching bug
+
+2006-09-16 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Rename new utimes() method to more logical utimens()
+
+2006-09-14 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Fuse tried to unlink already unlinked hidden files. Bug
+ reported by Milan Svoboda
+
+2006-09-10 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Released 2.6.0-rc1
+
+2006-09-10 Miklos Szeredi <miklos@szeredi.hu>
+
+ * kernel: Fix unlock on close for kernels < 2.6.18
+
+ * Add ulockmgr library & server. This can be used for handling
+ file locking requests either directly from libfuse or over a
+ network, etc. This first version is not optimized and the number
+ of file descriptors it uses may get out of hand
+
+2006-09-07 Miklos Szeredi <miklos@szeredi.hu>
+
+ * lib: Add interrupt support to high level library, which may be
+ enabled with the 'intr' mount option.
+
+ * When an operation is interrupted the thread handling that
+ operation will receive SIGUSR1 (or other signal specified with the
+ 'intr_signal=N' option). The library installs a no-op signal
+ handler for this signal, unless there's already a handler
+ installed.
+
+ * The filesystem may query interrupt status (regardless of 'intr')
+ with the fuse_interrupted() function.
+
+ * mount.fuse: initialize $HOME if not set. Report from Sven Goldt
+
+2006-09-03 Miklos Szeredi <miklos@szeredi.hu>
+
+ * lib: Multithreaded loop now allows unlimited number of threads.
+ This is needed for locking operations which may block
+ indefinitely. Also the kernel now doesn't limit the number of
+ outstanding requests so the library shouldn't do so either.
+
+2006-09-01 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Fix recursive lock bug in interrupt handling
+
+ * Add utimes() method to highlevel interface, which supports
+ setting times with nanosecond resolution
+
+2006-08-18 Miklos Szeredi <miklos@szeredi.hu>
+
+ * kernel: fix page leak if fuse_readpages() failed in it's
+ initialization. Bug found and original patch from Alexander
+ Zarochentsev
+
+ * For linux kernels >=2.6.18 (2.6.19 if using the fuse module from
+ the kernel tree) the statfs method will receive the path within
+ the filesystem on which the stat(v)fs syscall was called
+
+ * fusermount: try to modprobe fuse module if invoked by root and
+ unable to open device. This is needed with udev, since the device
+ node will be created only when the module is inserted, hence
+ module autoloading won't work. Reported by Szakacsits Szabolcs
+
+2006-07-30 Miklos Szeredi <miklos@szeredi.hu>
+
+ * fusermount: if selinux is active, restore the original file's
+ security context in unmount_rename(). Redhat bugzilla id 188561.
+ Patch from Yves Perrenoud
+
+ * Add POSIX file locking operation to high level library
+
+ * Initialize context for unlink of hidden files on umount. Bug
+ reported by Tim Stoakes
+
+2006-07-14 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Multiple release() calls can race with each other, resulting in
+ the hidden file being deleted before the last release finishes.
+ Bug found and patch tested by Mark Huijgen
+
+2006-07-05 Miklos Szeredi <miklos@szeredi.hu>
+
+ * fusermount: if /dev/fuse doesn't exist, suggest modprobing fuse;
+ this makes sense on systems using udev. Reported by Szakacsits
+ Szabolcs
+
+2006-06-29 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Released 2.6.0-pre3
+

+ * Add missing pthread_rwlock_destroy(). Patch from Remy Blank
+
+2006-06-05 Remy Blank <remy.blank@pobox.com>

+ * lib: canonicalize mount point in fuse_helper_opt_proc() so that
+ unmounting succeeds even if mount point was relative.
+
+2006-06-04 Csaba Henk <csaba.henk@creo.hu>
+
+ * lib: fix emergency umount in helper.c when malloc fails.
+ (The way it was done would end up in a segfault.)
+
+2006-06-01 Csaba Henk <csaba.henk@creo.hu>
+
+ * lib: adjust threading related compiler flags.
+ Switch to "-pthread" from "-lpthread" as that's the preferred
+ one on several platforms. Consulted with Terrence Cole and
+ Miklos Szeredi
+
+2006-05-08 Miklos Szeredi <miklos@szeredi.hu>
+
+ * lib: search fusermount in installation directory (bindir) as
+ well as in PATH.
+
+2006-05-03 Miklos Szeredi <miklos@szeredi.hu>
+
+ * lib: fix compilation if CLOCK_MONOTONIC is not defined.
+ Reported by Christian Magnusson
+
+2006-04-23 Csaba Henk <csaba.henk@creo.hu>
+
+ * lib: make FreeBSD mount routine recognize if kernel features
+ backgrounded init and if it does, run the mount util in foreground
+ (similarly to Linux)
+
+2006-04-21 Miklos Szeredi <miklos@szeredi.hu>
+
+ * kernel: fix fput deadlock fix, the lockless solution could lead
+ to "VFS: busy inodes after umount..."
+
+ * kernel: fix race between checking and setting file->private_data
+ for the device. Found by Al Viro
+
+2006-04-11 Miklos Szeredi <miklos@szeredi.hu>
+
+ * kernel: remove request pool, instead allocate requests on
+ demand. Account the number of background requests, and if they go
+ over a limit, block the allocation of new requests.
+
+ * kernel: fix deadlock if backgrounded request holds the last
+ reference to the super block
+
+ * kernel: don't use fuse_reset_request() during direct I/O
+
+2006-04-06 Csaba Henk <csaba.henk@creo.hu>

+
+2006-04-01 Miklos Szeredi <miklos@szeredi.hu>
+
+ * lib: Add missing rwlock initialization. Patch by Ryan Bradetich
+
+2006-03-17 Miklos Szeredi <miklos@szeredi.hu>
+
+ * API changes:
+
+ * fuse_main(), fuse_setup() and fuse_new() have an additionl
+ user_data parameter
+
+ * fuse_mount() returns a 'struct fuse_chan' pointer instead of a
+ file descriptor
+
+ * fuse_unmount() receives a 'struct fuse_chan' pointer. It
+ destroys the given channel
+
+ * fuse_teardown() no longer has a file descriptor parameter
+
+ * new exported functions: fuse_session_remove_chan(),
+ fuse_get_session(), fuse_daemonize()
+
+ * fuse_chan_recv() may now return a new channel which will be used
+ to send the reply
+
+2006-03-16 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Released 2.6.0-pre2
+
+2006-03-16 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Don't unmount if already unmounted. This fixes a problem seen
+ in the following situation: Lazy unmount a busy filesystem; Mount
+ a new one in top; When the first finally unmounts, the second also
+ unmounts. Reported by Franco Broi
+
+2006-03-15 Miklos Szeredi <miklos@szeredi.hu>
+
+ * lowlevel lib: use indirect function calls instead of a
+ switch/case construct. Besides increased efficiency it helps
+ maintainability & readability too. Patch from Florin Malita
+
+2006-03-13 Miklos Szeredi <miklos@szeredi.hu>
+
+ * kernel: replace global spinlock with a per-connection spinlock

+ interface to return -errno in case of error.
+
+2006-03-01 Csaba Henk <csaba.henk@creo.hu>
+
+ * libfuse: pass device file descriptor to fuse_unmount(), rewrite
+ FreeBSD implementation so that it uses libc (sysctl backed) instead
+ of an embdedded script (kmem backed). Adjust the control flow of
+ hello_ll so that device doesn't get closed before unmount attempt.
+
+2006-02-25 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Lowlevel lib: return all-zero statvfs data if filesystem doesn't
+ implement method. This is needed on FreeBSD, and nicer on Linux
+ too. Highlevel lib already did this. Reported by Csaba Henk
+
+ * Fix negative entry handling. There was a bug, that negative
+ lookups with timeouts (nodeid == 0) returned -EIO.
+
+2006-02-23 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Fix race between RELEASE and UNLINK, which might leave
+ .fuse_hidden* files around
+
+2006-02-21 Miklos Szeredi <miklos@szeredi.hu>
+
+ * fusexmp_fh: implement flush() method and call close() on the
+ open file descriptor. This is needed if used on an NFS
+ filesystem, which buffers data until file is closed. Franco Broi
+ spotted the situation when 'cp -p' failed to set the modification
+ time because of this.
+
+2006-02-20 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Released 2.6.0-pre1
+
+2006-02-19 Miklos Szeredi <miklos@szeredi.hu>
+

+ ID: 352631. Found by Stéphane Rosi
+
+2006-02-17 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Lowlevel lib: Unify fuse_dirent_size() and fuse_add_dirent()
+ into a single function fuse_add_direntry(). This cleans up the
+ interface and makes it possible to do stacking.
+
+2006-02-16 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Fix rare race betweeen abort and release caused by failed iget()
+ in fuse_create_open().
+
+ * Add 'ac_attr_timeout' option e.g. for filesystems which do their
+ own attribute caching.
+
+2006-02-15 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Work around FreeBSD runtime linker "feature" which binds an old
+ version of a symbol to internal references if the symbol has more
+ than one version. This resulted in infinite recursion in
+ fuse_lowlevel_new_compat25().
+
+2006-02-10 Csaba Henk <csaba.henk@creo.hu>

+
+ * Add connection info to ->init() methods to both lowlevel and

+
+ * Fall back to synchronous read() behavior if either library or

+ * fuse_opt: add new fuse_opt_insert_arg() function, which is
+ needed by filesystems to implement some argument manipulations
+ correctly
+
+ * fuse_opt: fix memory leak in handling "--" option
+
+2006-01-18 Miklos Szeredi <miklos@szeredi.hu>
+
+ * kernel: fix detection of case when fuse is not configured into
+ the kernel either as module or built-in
+
+ * fuse_opt.h: fix incompatibility with C++ compilers by renaming
+ 'template' structure member to 'templ'. Reported by Takashi Iwai
+
+ * fuse.h: fix compatibility bugs. Patch by Yura Pakhuchiy
+
+ * kernel: support version 2.6.16 (i_sem -> i_mutex)
+
+2006-01-16 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Added (again) asynchronous readpages support
+
+ * Each connection now shows up under /sys/fs/fuse/connections
+
+ * Connection attributes exported to sysfs: 'waiting' number of
+ waiting requests; 'abort' abort the connection
+
+ * Connection may be aborted through either the sysfs interface or
+ with 'umount -f mountpoint'
+
+2006-01-14 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Released 2.5.0
+
+2006-01-14 Miklos Szeredi <miklos@szeredi.hu>
+
+ * kernel: fix a couple of bugs
+
+ * Order of request_end() and fuse_copy_finish() was wrong.
+ Posthumous note: Franco Broi managed to exploit this, though it
+ seemed quite impossible
+
+ * request_end() used request pointer after decrementing refcount
+
+ * Clearing ->connected or ->mounted connection flags could race
+ with setting other bitfields not protected with a lock
+
+2006-01-10 Miklos Szeredi <miklos@szeredi.hu>
+
+ * kernel: add necessary compile flags for 2.4.X/x86_64.
+ Report from Sean Ziegeler
+
+2006-01-09 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Released 2.5.0-pre2
+
+2006-01-09 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Applied patch from Csaba Henk, to update mount_bsd to new
+ fuse_mount() semantics
+
+ * Ignore auto,noauto,... options in mount.fuse. Reported by Frank
+ Steiner and Don Taber
+
+ * fusermount: add 'dirsync' mount option
+
+2006-01-07 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Improved help reporting and added version reporting to library
+
+2006-01-06 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Change working directory to "/" even if running in the
+ foreground. Patch from Jonathan Brandmeyer
+
+ * Changed lots of functions to use 'struct fuse_args' instead of
+ separate argc and argv
+
+ * Added fuse_parse_cmdline(), fuse_set_signal_handlers() and
+ fuse_remove_signal_handlers() functions, so that it's now pretty
+ easy to get all the functionality of fuse_main() with a filesystem
+ using the lowlevel API.
+
+2006-01-02 Miklos Szeredi <miklos@szeredi.hu>
+
+ * mount.fuse: the 'user' option should be ignored. Report and
+ solution from Mattd.
+
+ * mount.fuse: export PATH in the right place. Report and patch
+ from Hannes Schweizer
+
+2005-12-16 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Clean up the option parsing interface slightly, by creating an
+ "argument list" structure, that contains the argument vector and
+ count
+
+2005-12-15 Miklos Szeredi <miklos@szeredi.hu>
+
+ * fusermount: check if /mnt/mtab is a symlink and don't modify it
+ in that case
+
+ * kernel: simplify request size limiting. INIT only contains
+ maximum write size, maximum path component size remains fixed at
+ 1024 bytes, and maximum xattr size depends on read buffer.
+
+2005-12-14 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Fix readdir() failure on x86_64, of 32bit programs compiled
+ without largefile support. Bug report and help from Anthony
+ Kolasny
+
+ * If lookup returns invalid mode, return -EIO instead of creating

+
+2005-12-07 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Return EIO for file operations (read, write, fsync, flush) on

+ "bad" if their type changes. Bug report by Csaba Henk
+
+2005-12-06 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Use bigger request buffer size. write() did not work on archs

+
+ * Extend INIT reply with data size limits
+
+2005-12-02 Miklos Szeredi <miklos@szeredi.hu>

+
+2005-11-29 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Check if '-msoft-float' option is supported by compiler when
+ configuring for a 2.4.x kernel. Bug report by Mark Haney
+
+ * In multithreaded loop send a TERM signal to the main thread if
+ one of the other threads exit. Needed on FreeBSD for a clean exit
+ on umount. Should not cause any harm on Linux either
+
+2005-11-28 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Fix bug in 32-bit file handle compatibility
+
+2005-11-27 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Block TERM, INT, HUP and QUIT signals in all but the main
+ thread. According to POSIX it's not specified which thread will
+ receive these signals.
+
+ * Kernel changes:
+
+ * Check for directory aliasing on mkdir, not just on lookup
+
+ * Check for special node ID values in create+open operation
+
+ * Sync with -mm: readv, writev, aio_read and aio_write methods
+ added to file operations
+
+ * Cleanups: lookup code, page offset calculation
+
+ * ABI stepped to 7.4, changes:
+
+ * frsize member added to fuse_kstatfs structure
+
+ * added support for negative entry caching: on lowlevel API if
+ fuse_entry_param::ino is set to zero in reply to a lookup request,
+ the kernel will cache the dentry for the specified amount of time.
+
+ * libfuse: added 'negative_timeout' option: specifies how much
+ negative entries should be cached. Default is zero, to be
+ compatible with prior versions
+
+2005-11-22 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Add detection of mainline FUSE code in running kernel
+
+2005-11-21 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Don't use async cancelation in multithreaded loop. This makes
+ it more portable to systems where read() is not async cancel safe.
+ Report from Andriy Gapon
+
+2005-11-20 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Warn if API version 11 compatibility is requested

+
+ * More FreeBSD merge
+
+ * fusermount: don't allow mountpoints with '\n', '\t', or '\\' in
+ them, because it corrupts /etc/mtab. Found by Thomas Biege
+ CVE-2005-3531
+
+ * libfuse: don't use system() to invoke 'fusermount -u ...'
+ because it breaks mountpoints with spaces in them into multiple

+
+2005-11-16 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Merge library part of FreeBSD port. Patch by Csaba Henk
+
+2005-11-11 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Use 64bit type for file handle, so the full range supported by
+ the kernel interface is available to applications
+
+2005-11-10 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Moved mountpoint argument checking from fuse_parse_cmdline() to
+ fuse_mount() in preparation to FreeBSD merge.
+
+2005-11-08 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Remove unneeded close() from fuse_teardown(). Spotted by Csaba

+
+2005-11-07 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Make the statfs change backwards compatible.
+
+2005-11-06 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Change ->statfs() method to use 'struct statvfs' instead of
+ 'struct statfs'. This makes the API more portable since statvfs()
+ is defined by POSIX.
+
+2005-10-28 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Add fgetattr() method, which currently will only be called after
+ a successful call to a create() method.
+
+2005-10-26 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Change kernel ABI version to 7.3
+
+ * Add ACCESS operation. This is called from the access() system
+ call if 'default_permissions' mount option is not given, and is
+ not called on kernels 2.4.*
+
+ * Add atomic CREATE+OPEN operation. This will only work with
+ 2.6.15 (presumably) or later Linux kernels.
+
+ * Add ftruncate() method. This will only work with 2.6.15
+ (presumably) or later Linux kernels.
+
+ * Fix kernel module compile if kernel source and build directories
+ differ. Report and initial patch by John Eastman
+
+2005-10-18 Miklos Szeredi <miklos@szeredi.hu>

+
+ * Check for special node ID values in lookup and creation
+
+2005-09-22 Miklos Szeredi <miklos@szeredi.hu>

+ with O_DIRECT flag.
+
+2005-09-20 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Remove '--enable-auto-modprobe' configure flag. Module

+
+2005-09-15 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Install UDEV rule file, so /dev/fuse is created with mode 0666.
+ Help from Jens M. Noedler.
+
+2005-09-14 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Add memory cleanup on thread exit
+
+2005-09-13 Miklos Szeredi <miklos@szeredi.hu>
+

+
+2005-09-12 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Don't ignore read error in multithreaded loop
+

+
+ * Released 2.4.0-pre2
+
+2005-09-08 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Revert lock and access operations. Postpone these until 2.5.
+
+2005-09-02 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Fix compile warning on 2.6.13 and later
+
+ * Fix compilation on old kernels
+
+2005-08-19 Miklos Szeredi <miklos@szeredi.hu>
+

+
+2005-08-15 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Released 2.4.0-pre1
+
+2005-08-14 Miklos Szeredi <miklos@szeredi.hu>
+
+ * lib: cleaned up (or messed up, depending on your POV) the low
+ level library API. Hopefully this is close to the final form.
+
+2005-08-05 Miklos Szeredi <miklos@szeredi.hu>
+
+ * fusermount: don't allow empty mountpoint argument, which defeats
+ automatic umounting in fuse_main(). Bugreport by Václav Jůza
+
+2005-08-03 Miklos Szeredi <miklos@szeredi.hu>
+
+ * fix warnings in fuse.h and fuse_lowlevel.h if -Wshadow compiler
+ option is used (Paul Alfille).
+
+2005-08-02 Miklos Szeredi <miklos@szeredi.hu>
+
+ * highlevel-lib: added mount options "attr_timeout" and
+ "entry_timeout". These options control the length of time file
+ attributes and entries (names) are cached. Both default to 1.0
+ second.
+
+ * kernel: correctly handle zero timeout for attributes and entries
+
+2005-08-01 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Added missing symbols to versionscript (Joshua J. Berry)
+
+ * kernel: implement two flags, open can set: 'direct_io' and
+ 'keep_cache'. These correspond exactly to mount options
+ 'direct_io' and 'kernel_cache', but allow a per-open setting.
+
+ * Move 'direct_io' and 'kernel_cache' mount option handling to
+ userspace. For both mount options, if the option is given, then
+ the respective open flag is set, otherwise the open flag is left
+ unmodified (so the filesystem can set it).
+
+ * lib (highlevel): make open method optional
+
+2005-07-28 Miklos Szeredi <miklos@szeredi.hu>
+
+ * kernel: invalidate attributes for read/readdir/readlink
+ operations
+
+ * kernel: detect newer UML kernels
+
+2005-07-26 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Make the installation path of fuse.ko and mount.fuse

+
+2005-07-22 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Fix bug, that causes filesystem requests to hang when unique
+ request counter becomes negative. This happens after
+ 2,147,483,648 operations, so most people won't care. Thanks to
+ Franco Broi for the report and testing.
+
+2005-07-21 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Don't change mtime/ctime/atime to local time on read/write.
+ Bug reported by Ben Grimm
+
+ * Install fuse_common.h and fuse_lowlevel.h. Report by Christian
+ Magnusson
+
+ * fusermount: use getopt_long() for option parsing. It allows the
+ use of '--' to stop argument scanning, so fusermount can now
+ operate on directories whose names begin with a '-'. Patch by
+ Adam Connell
+
+2005-07-15 Miklos Szeredi <miklos@szeredi.hu>
+
+ * fusermount: add '-v', '--version' and '--help' options
+
+ * add inode based API
+
+2005-07-12 Miklos Szeredi <miklos@szeredi.hu>
+
+ * lib: don't block signals in worker threads. Problem noticed by

+
+2005-07-07 Miklos Szeredi <miklos@szeredi.hu>
+
+ * lib: don't allow both 'allow_other' and 'allow_root' options to
+ be given
+
+2005-07-06 Miklos Szeredi <miklos@szeredi.hu>
+
+ * fusermount: check if mountpoint is empty (only '.' and '..' for
+ directories, and size = 0 for regular files). If "nonempty"
+ option is given, omit this check. This is useful, so users don't
+ accidentally hide data (e.g. from backup programs). Thanks to
+ Frank van Maarseveen for pointing this out.
+
+ * kernel: check if mandatory mount options ('fd', 'rootmode',
+ 'user_id', 'group_id') are all given
+
+ * lib: simplify 'readdir_ino' handling
+
+ * lib: add mount options 'umask=M', 'uid=N', 'gid=N'
+
+2005-07-03 Miklos Szeredi <miklos@szeredi.hu>
+
+ * kernel: clean up 'direct_io' code

+
+2005-06-08 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Enable the auto-loading of the module via access to the
+ corresponding device file. Patch by Takashi Iwai.
+
+ * Allow mounting a regular file (over a regular file) for
+ unprivleged users.
+
+ * Do not create temporary device file. Require "/dev/fuse" to
+ exist, and be readable/writable by the mounting user.
+
+2005-06-02 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Released 2.3.0
+
+2005-06-02 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Fix serious information leak: if the filesystem returns a short
+ byte count to a read request, and there are non-zero number of
+ pages which are not filled at all, these pages will not be zeroed.
+ Hence the user can read out previous memory contents. Found by
+ Sven Tantau.
+
+2005-05-27 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Add "readdir_ino" mount option, which tries to fill in the d_ino
+ field in struct dirent. This mount option is ignored if "use_ino"
+ is used. It helps some programs (e.g. 'pwd' used over NFS from a
+ non-Linux OS). Patch by David Shaw.
+
+2005-05-12 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Released 2.3-rc1
+
+2005-05-12 Miklos Szeredi <miklos@szeredi.hu>
+
+ * File save in krusader and other editors doesn't work with sshfs,
+ because open() is interrupted by a periodic signal, and open()
+ restarts forever, without any progress. This could just be fixed
+ in open(), but the problem is more generic: if signals are
+ received more often than the filesystem can get the request to
+ userspace, it will never finish. This is probably only a
+ theoretical problem, nevertheless I'm removing the possibility to
+ interrupt requests with anything other than SIGKILL, even before
+ being sent to userspace. Bugreport by Eduard Czimbalmos.
+
+2005-05-09 Miklos Szeredi <miklos@szeredi.hu>
+
+ * libfuse: add "tree_lock" rwlock, that is locked for write in
+ rename, unlink and rmdir, and locked for read in all other
+ operations. This should fix the rename/release race reported by
+ Valient Gough and others. The solution is very coarse, a finer
+ grained locking scheme could be implemented, but it would be much
+ more complex. Let's see whether this is good enough.
+
+2005-05-09 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Released 2.3-pre7
+
+2005-05-08 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Better fix for out of order FORGET messages. Now the
+ LOOKUP/FORGET messages are balanced exactly (one FORGET can
+ balance many lookups), so the order no longer matters. This
+ changes the kernel ABI slightly, but the library remains backward
+ compatible.
+
+2005-05-06 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Fix abort for out of order FORGET messages. Again. Spotted by
+ Franco Broi again. Sorry :)
+
+2005-04-29 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Released 2.3-pre6
+
+2005-04-29 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Make fusermount work with fuse kernel modules not yet supporting
+ the "group_id" option (added for the purpose of stricter
+ permission checking).
+
+2005-04-28 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Check for hard-linked directories in lookup. This could cause
+ problems in the VFS, which assumes that such objects never exist.
+
+ * Make checking of permission for other users more strict. Now
+ the same privilege is required for the mount owner as for ptrace
+ on the process performing the filesystem operation.
+
+2005-04-23 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Released 2.3-pre5
+
+2005-04-22 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Add -msoft-float to kernel module compile flags for 2.4.X. This

+ Reported by David Shaw
+
+ * Remove "allow_root" option from kernel module, and implement

+
+ * Released 2.3-pre1

+
+2005-03-08 Miklos Szeredi <miklos@szeredi.hu>
+
+ * examples: add -lpthread to link flags to work around valgrind
+ quirk
+
+ * lib: don't exit threads, so cancelation doesn't cause segfault
+
+2005-03-04 Miklos Szeredi <miklos@szeredi.hu>
+
+ * kernel: fix nasty bug which could cause an Oops under certain
+ situations. Found by Magnus Johansson
+
+2005-02-28 Miklos Szeredi <miklos@szeredi.hu>
+
+ * libfuse: added opendir() method. This can be used in case
+ permission checking in getdir() is too late. Thanks to Usarin
+ Heininga for pointing out this deficiency
+
+ * libfuse: added init() and destroy() methods to fuse_operations
+
+ * kernel: llseek() method for files and directories made explicit
+
+ * kernel: fixed inode leak in NFS export in case of nodeid
+ wrapping
+
+2005-02-15 Miklos Szeredi <miklos@szeredi.hu>
+
+ * libfuse: clean up some unitialized memory found with valgrind
+
+ * Add -lpthread to Libs in fuse.pc. Valgrind seems to need an
+ explicitly linked libpthread for applications
+
+2005-02-10 Miklos Szeredi <miklos@szeredi.hu>
+
+ * fusermount: set umask, otherwise /etc/mtab will have
+ unpredictable permission. Spotted by Jindrich Kolorenc
+
+ * fusermount: set owner and group of /etc/mtab to original values
+ on unmount
+
+ * libfuse: add 'use_ino' option to help. Patch by Valient Gough
+
+2005-02-07 Miklos Szeredi <miklos@szeredi.hu>

+
+2005-02-02 Miklos Szeredi <miklos@szeredi.hu>
+

+
+2005-02-02 Miklos Szeredi <miklos@szeredi.hu>
+

+
+2005-01-21 Miklos Szeredi <miklos@szeredi.hu>
+
+ * LIB: fix double reply in readdir operation
+
+ * fusermount: fix uid checking bug. Patch by Adam Connell
+
+ * KERNEL: fix compile on various RedHat patched 2.4 kernels.
+ Patch by Keshava Gowda
+
+2005-01-20 Miklos Szeredi <miklos@szeredi.hu>
+
+ * KERNEL: provide correct llseek semantics for fuse device (fixes
+ a bug on Progeny 2.4.20 kernel). Reported by Valient Gough
+
+2005-01-20 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Released 2.2-pre5 (matches kernel 2.6.11-rc1-mm2)
+
+2005-01-18 Miklos Szeredi <miklos@szeredi.hu>
+
+ * KERNEL ABI: remove GETDIR operation, and add OPENDIR, READDIR
+ and RELEASEDIR. This ends the ugly hack of passing a file
+ descriptor to the kernel, and actually makes the code simpler.
+
+2005-01-17 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Released 2.2-pre4
+
+2005-01-17 Miklos Szeredi <miklos@szeredi.hu>
+
+ * fusermount: remove capability setting, which was the cause of
+ problems for some users. It seems that FS related capabilities
+ are removed by setfsuid(), so this isn't even needed.
+
+2005-01-15 Miklos Szeredi <miklos@szeredi.hu>
+
+ * fix compilation on 2.4 kernels (reported by Valient Gough)
+
+ * fix failure to unmount bug (found by David Shaw)
+
+ * fusermount: improve parsing of /etc/fuse.conf
+
+2005-01-13 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Remove 'mount_max' and 'user_allow_other' module options. These
+ are now checked by fusermount, and can be set in /etc/fuse.conf
+
+ * KERNEL: change check for fsid == 0 to capable(CAP_DAC_OVERRIDE)
+
+2005-01-11 Miklos Szeredi <miklos@szeredi.hu>
+
+ * KERNEL: fix possible inode allocation problem, where
+ sizeof(struct inode) is not aligned (found by Mike Waychison)
+
+ * KERNEL: use new follow_link/put_link methods
+
+ * KERNEL: cosmetic fixes
+
+2005-01-10 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Released 2.2-pre3
+
+2005-01-10 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Add missing code that was accidently left out
+
+2005-01-09 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Released 2.2-pre2
+
+2005-01-09 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Change "uid" mount option to "user_id" to avoid confusion with a
+ mount option "uid" commonly used by many filesystems
+
+2005-01-09 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Released 2.2-pre1
+
+2005-01-09 Miklos Szeredi <miklos@szeredi.hu>
+
+ * If FUSE is configured in the kernel, don't build it by default
+
+2005-01-07 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Compile fix by Christian Magnusson
+
+2005-01-05 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Fix compilation for 2.6.{0-5} kernels
+
+2005-01-04 Miklos Szeredi <miklos@szeredi.hu>
+
+ * KERNEL: if request is interrupted, still keep reference to used
+ inode(s) and file, so that FORGET and RELEASE are not sent until
+ userspace finishes the request.
+
+ * remove /{sys,proc}/fs/fuse/version, and instead add an INIT
+ request with the same information, which is more flexible,
+ simpler, works on embedded systems.
+
+2004-12-16 Miklos Szeredi <miklos@szeredi.hu>
+
+ * KERNEL ABI: update interface to make it independent of type
+ sizes. This will help on 64 bit architectures which can run
+ legacy 32 bit applications.
+
+ * KERNEL ABI: add "len" field to request headers. This will allow
+ sending/receiving requests in multiple chunks.
+
+ * KERNEL: handle file type change more intelligently
+
+ * LIB: "-o debug" option should disable backgrounding (fix by
+ Fabien Reygrobellet)
+
+2004-12-13 Miklos Szeredi <miklos@szeredi.hu>
+
+ * KERNEL: invalidate dentry/attributes if interrupted request
+ could leave filesystem in an unknown state.
+
+2004-12-12 Miklos Szeredi <miklos@szeredi.hu>
+
+ * KERNEL: lots of cleanups related to avoiding possible deadlocks.
+ These will cause some regressions, but stability is considered
+ more important. If any of these features turns out to be
+ important, it can be readded with the deadlock problems addressed.
+
+ * Make all requests interruptible (only with SIGKILL currently).
+ This can be used to break any deadlock produced by the userspace
+ filesystem accessing it's own exported files. The RELEASE request
+ is special, because if it's interrupted before sending it to
+ userspace it is still sent, but the reply is not awaited.
+
+ * If request is interrupted before being sent to userspace, and if
+ it hasn't yet got any side effects, it is always restarted,
+ regardless of the SA_RESTART flag. This makes these interruptions
+ transparent to the process.
+
+ * Remove shared-writable mmap support, which was prone to an
+ out-of-memory deadlock situation
+
+ * Remove INVALIDATE userspace initiated request
+
+ * Make readpages() synchronous. Asynchronous requests are
+ deadlock prone, since they cannot be interrupted.
+
+ * Add readv/writev support to fuse device operations
+
+ * Remove some printks, which userspace FS can use for a DoS
+ against syslog
+
+ * Remove 'large_read' mount option from 2.6 in kernel, check it in
+ fusermount instead
+
+ * LIB: improve compatibility with a fuse.h header installed in
+ ${prefix}/include which in turn includes the real header.
+
+ * LIB: improve compatibility by defining fuse_main() (which is now
+ not used), so old configure scripts find it.
+
+2004-12-10 Miklos Szeredi <miklos@szeredi.hu>
+
+ * When mounting on a subdirectory of / don't duplicate slashes at
+ the beggining of path (spotted by David Shaw)
+
+2004-12-09 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Fix bug causing garbage in mount options (spotted by David Shaw)
+
+2004-12-07 Miklos Szeredi <miklos@szeredi.hu>

+
+ * More comments in fuse.h
+
+ * Get rid of double underscores
+
+2004-12-04 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Add -D_FILE_OFFSET_BITS=64 to cflags provided by pkg-config
+
+ * helper.c: add -ho option, which only displays the options not
+ the usage header. This can be used by filesystems which have
+ their own options.
+
+2004-12-03 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Add source compatibility to 2.1 and 1.1 APIs. To select betwen
+ versions simply define FUSE_USE_VERSION to 22, 21 or 11 before
+ including the fuse header
+
+ * Add binary compatibility to 2.1 version of library with symbol
+ versioning
+
+2004-12-03 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Released 2.1
+
+2004-12-01 Miklos Szeredi <miklos@szeredi.hu>
+

+
+2004-11-30 Miklos Szeredi <miklos@szeredi.hu>
+
+ * kernel: clean up reading functions

+2004-11-29 Miklos Szeredi <miklos@szeredi.hu>
+
+ * kernel: make readpage() uninterruptible
+
+ * kernel: check readonly filesystem flag in fuse_permission
+
+ * lib: don't die if version file not found and new style device
+ exists
+
+ * lib: add '-r' option, which is short for '-o ro'
+
+ * fusermount: simplify device opening
+
+ * kernel: when direct_io is turend on, copy data directly to
+ destination without itermediate buffer. More efficient and safer,
+ since no allocation is done.
+
+ * fusermount: fix warning if fuse module is not loaded
+
+ * kernel: use /dev/fuse on 2.4 too
+
+2004-11-26 Miklos Szeredi <miklos@szeredi.hu>
+
+ * libfuse API change: open, read, write, flush, fsync and release
+ are passed a 'struct fuse_file_info' pointer containing the open
+ flags (open and release), and the file handle. Verion changed to
+ 3.0.
+
+2004-11-23 Miklos Szeredi <miklos@szeredi.hu>
+
+ * More cleanups in the kernel
+
+ * The 10,229 charater device number has been assigned for FUSE
+
+ * Version file checking fix (reported by Christian Magnusson)
+
+ * fusermount: opening the fuse device now doesn't need /sys.
+
+ * Optimize reading by controlling the maximum readahead based on
+ the 'max_read' mount option
+
+ * fixes for UCLIBC (Christian Magnusson)
+
+2004-11-19 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Cleaned up kernel in preparation for merge into mainline:
+
+ * Use /sys/fs/fuse/version instead of /proc/fs/fuse/version
+
+ * Use real device (/dev/fuse) instead of /proc/fs/fuse/dev
+
+ * __user annotations for sparse
+
+ * allocate individual pages instead of kmalloc in fuse_readdir,
+ fuse_read and fuse_write.
+
+ * Fix NFS export in case "use_ino" mount option is given
+
+ * Make libfuse and fusermount compatible with future versions
+
+ * fusermount: properly add mount options to /etc/mtab
+
+2004-11-15 Miklos Szeredi <miklos@szeredi.hu>
+
+ * fusermount: do not resolve last component of mountpoint on if it
+ is '.' or '..'. This new path resolvation is now done on mount as
+ well as unmount. This enables relative paths to work on unmount.
+
+ * fusermount: parse common mount options like "ro", "rw", etc...
+
+ * Allow module params to be changed through sysfs
+
+2004-11-14 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Released 2.1-pre1
+
+2004-11-14 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Fix bug in fuse_readpages() causing Oops in certain situations.
+ Bug found by Vincenzo Ciancia.
+
+ * Fix compilation with kernels versions > 2.6.9.
+
+2004-11-11 Miklos Szeredi <miklos@szeredi.hu>

+ strangeness in case of mismatch.
+
+ * No need to allocate fuse_conn until actual mount happens
+
+ * Fix potential race between umount and fuse_invalidate
+
+ * Check superblock of proc file in addition to inode number
+
+ * Fix race between request_send_noreply() and fuse_dev_release()
+
+2004-11-10 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Separate configure for the kernel directory
+
+ * Don't allow write to return more than 'count'
+
+ * Extend kernel interface for future use
+
+2004-11-09 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Fix 'makeconf.sh' to use autoreconf if available
+
+2004-11-08 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Add ino argument to 'fuse_dirfil_t'. NOTE: This breaks source
+ compatibility with earlier versions. To compile earier versions
+ just add '-DFUSE_DIRFIL_COMPAT' compile flag or fix the source.
+ Do not use the "use_ino" mount flag with filesystems compiled with
+ FUSE_DIRFIL_COMPAT.
+
+ * Add pkg-config support. To compile a FUSE based filesystem you
+ can do "gcc -Wall `pkg-config --cflags --libs fuse` myfs.c -o myfs"
+ or similar. Note, that the PKG_CONFIG_PATH environment variable
+ usually needs to be set to "/usr/local/lib/pkgconfig".
+
+ * fuse.h is now installed in ${prefix}/include/fuse/
+
+2004-11-02 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Added "use_ino" mount option. This enables the filesystems to
+ set the st_ino field on files
+
+2004-11-01 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Fix compile problems with ancient (<=2.4.18) kernels (reported
+ by Jeremy Smith)
+
+ * Add "allow_root" mount option. Patch by Yaroslav Rastrigin
+
+ * Clear the 'exited' flag when mail loop is finished
+
+2004-10-28 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Make xattr functions work under 2.6 (bug found by Vincenzo
+ Ciancia)
+
+2004-10-26 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Reset request in fuse_flush() (bugreport by David Shaw)
+
+2004-10-21 Miklos Szeredi <miklos@szeredi.hu>
+
+ * fuse_main() now does not exit on error, rather it returns an
+ error code
+
+ * Exported __fuse_setup() and __fuse_teardown() functions, which
+ make it easier to implement a custom event loop.
+
+ * Use daemon() call to background the filesystem after mounting.
+ This function closes the standard input, output and error and
+ changes the current working directory to "/".
+
+2004-10-14 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Released 1.9
+
+2004-10-09 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Don't allow fuse_flush() to be interrupted (bug found by David
+ Shaw)
+
+2004-09-27 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Add PID to fuse_context. Patch by Steven James
+
+ * Change file handle type to 'unsigned long' in kernel interface
+
+2004-09-22 Miklos Szeredi <miklos@szeredi.hu>
+
+ * A slight API change: fuse_get_context() doesn't need the "fuse"
+ pointer, but the returned context contains it instead. The
+ fuse_get() function is not needed anymore, so it's removed.
+
+ * Fix mounting and umounting FUSE filesystem under another FUSE
+ filesystem by non-root (bug spotted by Valient Gough)
+
+2004-09-21 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Fix deadlock in case of memory allocation failure. Patch by
+ Christian Magnusson
+
+2004-09-16 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Check memory allocation failures in libfuse
+
+2004-09-14 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Check temporary file creation failure in do_getdir(). Bug
+ spotted by Terje Oseberg
+
+2004-09-13 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Allow "large_read" option for 2.6 kernels but warn of deprecation
+
+ * Make requests non-interruptible so race with FORGET is avoided.
+ This is only a temporary solution
+
+ * Support compiling FUSE kernel module on 2.4.x UML kernels
+
+2004-09-09 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Fix bug in case two FORGETs for the same node are executed in

+
+ * Add documentation of fuse internals by Terje Oseberg
+
+2004-08-16 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Change release method to be non-interruptible. Fixes bug
+ causing missing release() call when program which has opened files
+ is killed (reported by Franco Broi and David Shaw)
+
+2004-07-29 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Add fuse_invalidate() to library API
+
+2004-07-26 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Check permissions in setattr if 'default_permissions' flag is
+ set. Bug spotted by Damjan Lango
+
+2004-07-24 Miklos Szeredi <miklos@szeredi.hu>
+
+ * 'large_read' mount option removed for 2.6 kernels, since the
+ default (dynamic read size) is better
+
+ * Extend kernel API with file handles. A file handle is returned
+ by open, and passed to read, write, flush, fsync and release.
+ This is currently only used for debug output in the library.
+
+ * Security changes:
+
+ * Change the current directory to the mountpoint before checking
+ the permissions and mount filesystem on "."
+
+ * By default don't modprobe the fuse module for non-root. The old
+ behavior can be restored with the '--enable-auto-modprobe' flag of
+ ./configure
+
+ * By default don't allow shared writable mappings for non-root.
+ The old behavior can be restored with the 'user_mmap=1' module
+ parameter
+
+2004-07-23 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Clean up mount option passing to fusermount and to fuse_new()
+ BEWARE: this changes the userspace API slightly, and the command
+ line usage of programs using fuse_main()
+
+2004-07-20 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Optimize reading under 2.6 kernels by issuing multiple page
+ asynchronous read requests
+
+2004-07-18 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Only use redirty_page_for_writepage() for kernels >= 2.6.6
+
+2004-07-16 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Separate directory entry and inode attribute validity timer
+
+ * New write semaphore to stop page writeback during truncate
+
+ * Fsync now waits for all writes to complete before sending the
+ request
+
+ * Optimization: if a page is completely written by
+ fuse_commit_write(), clear the dirty flag and set the uptodate
+ flag for that page
+
+ * Some memory cleanup at exit
+
+2004-07-13 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Add FUSE_HARD_REMOVE flag, and '-i' option to fuse main, which
+ disable the "hide if open" behavior of unlink/rename.
+
+ * If temporary buffer allocation fails in raw read, fall back to a
+ smaller buffer
+
+2004-07-12 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Fix bug in do_open() in libfuse: open count was incremented
+ after the reply is sent so it could race with unlink/forget and
+ cause an abort.
+
+2004-07-08 Miklos Szeredi <miklos@szeredi.hu>
+
+ * When performing create or remove operation, refresh the parent's
+ attributes on next revalidate, as i_nlink (and maybe size/time)
+ could be inacurate.
+
+ * Use redirty_page_for_writepage() in fuse_writepage() for skipped
+ pages (2.6 only)
+
+ * Set set_page_dirty address space operation (2.6 only)
+
+2004-07-06 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Minor fix in read: print debug info even if read size is zero
+
+2004-07-04 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Fix race between truncate and writepage (fsx-linux now runs
+ without error)
+
+2004-07-02 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Fix kernel hang on mkfifo under 2.4 kernels (spotted and patch
+ by Mattias Wadman)
+
+ * Added option for direct read/write (-r)
+
+ * Fix revalidate time setting for newly created inodes
+
+ * Remove uid==0 check for '-x' option in fusermount (kernel checks
+ this)
+
+ * fuse_main() only installs handlers for signals (out of INT, HUP,
+ TERM, PIPE), for which no handler has yet been installed
+
+ * Add module option 'user_allow_other' which if set to non-zero
+ will allow non root user to specify the 'allow_other' mount option
+ ('-x' option of fusermount)
+
+ * Fix deadlock between page writeback completion and truncate
+ (bug found by Valient Gough with the fsx-linux utility)
+
+2004-07-01 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Change passing fuse include dir to 2.6 kernel make system more
+ robust (fixes compile problems seen on SuSE 9.1 with updated 2.6
+ kernel)
+
+2004-06-30 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Acquire inode->i_sem before open and release methods to prevent
+ concurrent rename or unlink operations.
+
+ * Make __fuse_read_cmd() read only one command. This allows
+ multiplexing the fuse file descriptor with other event sources
+ using select() or poll() (patch by Jeff Harris)
+
+ * Export 'exited' flag with __fuse_exited() (patch by Jeff Harris)
+
+2004-06-27 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Fix file offset wrap around at 4G when doing large reads
+
+2004-06-24 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Fix memory leak in open (Valient Gough)
+
+2004-06-24 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Add "close after delete" support to libfuse (patch by Valient
+ Gough)
+
+ * Cancel all worker threads before exit in multithreaded mode
+
+2004-06-23 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Fix locking bugs
+
+ * Don't send reply to RELEASE

+2004-06-22 Miklos Szeredi <miklos@szeredi.hu>
+
+ * No request allocation needed on inode and file release
+
+2004-06-21 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Fix possible inode leak in userspace in case of unfinished
+ lookup/mknod/mkdir/symlink/link operation.
+
+2004-06-20 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Fix some races and cleanups in fuse_read_super()
+
+2004-06-19 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Requests are allocated at open time
+
+2004-06-03 Miklos Szeredi <miklos@szeredi.hu>
+
+ * Build shared library as well as static (using libtool)
+
+ * Change FUSE_MINOR_VERSION from 1 to 0. I know it's illegal but
+ there has not been a release with the previous minor number, and I
+ hope nobody is using it for anything.
+
+ * Change fuse_main(), so that default behavior is to go into
+ background if mount is successful. '-f' and '-d' options disable
+ backgrounding. This fixes the "Why does my FUSE daemon hang?"
+ newbie complaint.
+
+ * Cache ENOSYS (function not implemented) errors on *xattr, flush

+
+ * Add file locking for mount/unmount (based on patch by Valient
+ Gough)
+
+2003-12-11 David McNab <david@rebirthing.co.nz>
+
+ * Python filesystem - was broken with python2.3, now fixed:
+ - changed PyTuple_* calls to PySequence_*, because os.lstat
+ is no longer returning a pure tuple
+ - changed PyInt_Check() calls to also call PyLong_Check,
+ to cover for cases (eg os.lstat) where longs are returned
+ - Added support for file 'release' handling, which IMO is
+ essential since this signals to a FS that writes to a file
+ are complete (and therefore the file can now be disposed of
+ meaningfully at the python filesystem's discretion)
+ - Added '__init__' handler to base Fuse class, which allows
+ your Python class to know the mountpoint and mount args,
+ as attributes myfs.mountpoint, myfs.optlist, myfs.optdict
+
+ * General:
+ - added 'mount.fuse' script (in util/ dir), which is meant to be
+ symlinked from /sbin, and which allows FUSE filesystems to
+ be mounted with the 'mount' command, and listed in fstab;
+ also, mount arguments get passed to your filesystem

-Libfuse for Android
+General Information
+===================
-FUSE[1] is a framework to develop userspace file systems for linux. Since Android is based on linux, it won't be too difficult to port libfuse to Android.
+FUSE (Filesystem in Userspace) is a simple interface for userspace
+programs to export a virtual filesystem to the Linux kernel. FUSE
+also aims to provide a secure method for non privileged users to
+create and mount their own filesystem implementations.
-The main problem of building and running libfuse on Android is that the bionic c library lacks support for pthread_cancel(), which is necessary for libfuse multi-thread code. This stackoverflow entry[2] has suggested a solution, which uses SIGUSR1 as an alternative. It seems to work.
+You can download the source code releases from
-Libfuse can be build with Android NDK[3]. If success, you will get libfuse.a and an example program fusexmp. To run the example, the android kernel should be built with FUSE kernel support.
+ http://sourceforge.net/projects/fuse

+or alternatively you can use CVS to get the very latest development

+
+
+Dependencies
+============
+
+Linux kernel version 2.6.X where X >= 9.
+
+Alternatively a kernel module from FUSE release 2.5.* can be used with
+this release, which supports kernels >= 2.4.21.
+
+Installation
+============
+
+./configure
+make
+make install
+modprobe fuse
+
+You may also need to add '/usr/local/lib' to '/etc/ld.so.conf' and/or
+run ldconfig.
+
+You'll also need a fuse kernel module, Linux kernels 2.6.14 or later
+contain FUSE support.
+
+For more details see the file 'INSTALL'
+
+How To Use
+==========
+
+FUSE is made up of three main parts:
+
+ - A kernel filesystem module
+
+ - A userspace library
+
+ - A mount/unmount program
+
+
+Here's how to create your very own virtual filesystem in five easy
+steps (after installing FUSE):
+
+ 1) Edit the file example/fusexmp.c to do whatever you want...
+
+ 2) Build the fusexmp program
+
+ 3) run 'example/fusexmp /mnt/fuse -d'
+
+ 4) ls -al /mnt/fuse
+
+ 5) Be glad
+
+If it doesn't work out, please ask! Also see the file 'include/fuse.h' for
+detailed documentation of the library interface.
+
+Security
+========
+
+If you run 'make install', the fusermount program is installed
+set-user-id to root. This is done to allow normal users to mount
+their own filesystem implementations.
+
+There must however be some limitations, in order to prevent Bad User from
+doing nasty things. Currently those limitations are:
+
+ - The user can only mount on a mountpoint, for which it has write
+ permission
+
+ - The mountpoint is not a sticky directory which isn't owned by the
+ user (like /tmp usually is)
+
+ - No other user (including root) can access the contents of the mounted
+ filesystem.
+
+Configuration
+=============
+
+Some options regarding mount policy can be set in the file
+'/etc/fuse.conf'
+
+Currently these options are:
+
+mount_max = NNN
+
+ Set the maximum number of FUSE mounts allowed to non-root users.
+ The default is 1000.
+
+user_allow_other
+
+ Allow non-root users to specify the 'allow_other' or 'allow_root'
+ mount options.
+
+
+Mount options
+=============
+
+Most of the generic mount options described in 'man mount' are
+supported (ro, rw, suid, nosuid, dev, nodev, exec, noexec, atime,
+noatime, sync async, dirsync). Filesystems are mounted with
+'-onodev,nosuid' by default, which can only be overridden by a
+privileged user.
+
+These are FUSE specific mount options that can be specified for all
+filesystems:
+
+default_permissions
+
+ By default FUSE doesn't check file access permissions, the
+ filesystem is free to implement it's access policy or leave it to
+ the underlying file access mechanism (e.g. in case of network
+ filesystems). This option enables permission checking, restricting
+ access based on file mode. This is option is usually useful
+ together with the 'allow_other' mount option.
+
+allow_other
+
+ This option overrides the security measure restricting file access
+ to the user mounting the filesystem. So all users (including root)
+ can access the files. This option is by default only allowed to
+ root, but this restriction can be removed with a configuration
+ option described in the previous section.
+
+allow_root
+
+ This option is similar to 'allow_other' but file access is limited
+ to the user mounting the filesystem and root. This option and
+ 'allow_other' are mutually exclusive.
+
+kernel_cache
+
+ This option disables flushing the cache of the file contents on
+ every open(). This should only be enabled on filesystems, where the
+ file data is never changed externally (not through the mounted FUSE
+ filesystem). Thus it is not suitable for network filesystems and
+ other "intermediate" filesystems.
+
+ NOTE: if this option is not specified (and neither 'direct_io') data
+ is still cached after the open(), so a read() system call will not
+ always initiate a read operation.
+
+auto_cache
+
+ This option enables automatic flushing of the data cache on open().
+ The cache will only be flushed if the modification time or the size
+ of the file has changed.
+
+large_read
+
+ Issue large read requests. This can improve performance for some
+ filesystems, but can also degrade performance. This option is only
+ useful on 2.4.X kernels, as on 2.6 kernels requests size is
+ automatically determined for optimum performance.
+
+direct_io
+
+ This option disables the use of page cache (file content cache) in
+ the kernel for this filesystem. This has several affects:
+
+ - Each read() or write() system call will initiate one or more
+ read or write operations, data will not be cached in the
+ kernel.
+
+ - The return value of the read() and write() system calls will
+ correspond to the return values of the read and write
+ operations. This is useful for example if the file size is not
+ known in advance (before reading it).
+
+max_read=N
+
+ With this option the maximum size of read operations can be set.
+ The default is infinite. Note that the size of read requests is
+ limited anyway to 32 pages (which is 128kbyte on i386).
+
+max_readahead=N
+
+ Set the maximum number of bytes to read-ahead. The default is
+ determined by the kernel. On linux-2.6.22 or earlier it's 131072
+ (128kbytes)
+
+max_write=N
+
+ Set the maximum number of bytes in a single write operation. The
+ default is 128kbytes. Note, that due to various limitations, the
+ size of write requests can be much smaller (4kbytes). This
+ limitation will be removed in the future.
+
+async_read
+
+ Perform reads asynchronously. This is the default
+
+sync_read
+
+ Perform all reads (even read-ahead) synchronously.
+
+hard_remove
+
+ The default behavior is that if an open file is deleted, the file is
+ renamed to a hidden file (.fuse_hiddenXXX), and only removed when
+ the file is finally released. This relieves the filesystem
+ implementation of having to deal with this problem. This option
+ disables the hiding behavior, and files are removed immediately in
+ an unlink operation (or in a rename operation which overwrites an
+ existing file).
+
+ It is recommended that you not use the hard_remove option. When
+ hard_remove is set, the following libc functions fail on unlinked
+ files (returning errno of ENOENT):
+ - read()
+ - write()
+ - fsync()
+ - close()
+ - f*xattr()
+ - ftruncate()
+ - fstat()
+ - fchmod()
+ - fchown()
+
+debug
+
+ Turns on debug information printing by the library.
+
+fsname=NAME
+
+ Sets the filesystem source (first field in /etc/mtab). The default
+ is the program name.
+
+subtype=TYPE
+
+ Sets the filesystem type (third field in /etc/mtab). The default is
+ the program name.
+
+ If the kernel suppports it, /etc/mtab and /proc/mounts will show the
+ filesystem type as "fuse.TYPE"
+
+ If the kernel doesn't support subtypes, the source filed will be
+ "TYPE#NAME", or if fsname option is not specified, just "TYPE".
+
+use_ino
+
+ Honor the 'st_ino' field in getattr() and fill_dir(). This value is
+ used to fill in the 'st_ino' field in the stat()/lstat()/fstat()
+ functions and the 'd_ino' field in the readdir() function. The
+ filesystem does not have to guarantee uniqueness, however some
+ applications rely on this value being unique for the whole
+ filesystem.
+
+readdir_ino
+
+ If 'use_ino' option is not given, still try to fill in the 'd_ino'
+ field in readdir(). If the name was previously looked up, and is
+ still in the cache, the inode number found there will be used.
+ Otherwise it will be set to '-1'. If 'use_ino' option is given,
+ this option is ignored.
+
+nonempty
+
+ Allows mounts over a non-empty file or directory. By default these
+ mounts are rejected (from version 2.3.1) to prevent accidental
+ covering up of data, which could for example prevent automatic
+ backup.
+
+umask=M
+
+ Override the permission bits in 'st_mode' set by the filesystem.
+ The resulting permission bits are the ones missing from the given
+ umask value. The value is given in octal representation.
+
+uid=N
+
+ Override the 'st_uid' field set by the filesystem.
+
+gid=N
+
+ Override the 'st_gid' field set by the filesystem.
+
+blkdev
+
+ Mount a filesystem backed by a block device. This is a privileged
+ option. The device must be specified with the 'fsname=NAME' option.
+
+entry_timeout=T
+
+ The timeout in seconds for which name lookups will be cached. The
+ default is 1.0 second. For all the timeout options, it is possible
+ to give fractions of a second as well (e.g. "-oentry_timeout=2.8")
+
+negative_timeout=T
+
+ The timeout in seconds for which a negative lookup will be cached.
+ This means, that if file did not exist (lookup retuned ENOENT), the
+ lookup will only be redone after the timeout, and the file/directory
+ will be assumed to not exist until then. The default is 0.0 second,
+ meaning that caching negative lookups are disabled.
+
+attr_timeout=T
+
+ The timeout in seconds for which file/directory attributes are
+ cached. The default is 1.0 second.
+
+ac_attr_timeout=T
+
+ The timeout in seconds for which file attributes are cached for the
+ purpose of checking if "auto_cache" should flush the file data on
+ open. The default is the value of 'attr_timeout'
+
+intr
+
+ Allow requests to be interrupted. Turning on this option may result
+ in unexpected behavior, if the filesystem does not support request
+ interruption.
+
+intr_signal=NUM
+
+ Specify which signal number to send to the filesystem when a request
+ is interrupted. The default is 10 (USR1).
+
+modules=M1[:M2...]
+
+ Add modules to the filesystem stack. Modules are pushed in the
+ order they are specified, with the original filesystem being on the
+ bottom of the stack.
+
+
+Modules distributed with fuse
+-----------------------------
+
+iconv
+`````
+Perform file name character set conversion. Options are:
+
+from_code=CHARSET
+
+ Character set to convert from (see iconv -l for a list of possible
+ values). Default is UTF-8.
+
+to_code=CHARSET
+
+ Character set to convert to. Default is determined by the current
+ locale.
+
+
+subdir
+``````
+Prepend a given directory to each path. Options are:
+
+subdir=DIR
+
+ Directory to prepend to all paths. This option is mandatory.
+
+rellinks
+
+ Transform absolute symlinks into relative
+
+norellinks
+
+ Do not transform absolute symlinks into relative. This is the default.
+
+
+Reporting bugs
