+                    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.

+                       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.

+2012-05-16  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Linking to a library that uses threads requires the application
+	to be linked with -pthreads otherwise some pthread functions will
+	be linked to stubs in glibc.  So move -pthread from Libs.private
+	to Libs in fuse.pc.  Reported by Werner Fink
+
+	* Fix the compile command in the examples. Reported by Luciano
+	Dalle Ore
+
+2012-04-20  Miklos Szeredi <miklos@szeredi.hu>
+

+
+2012-04-20  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Add missing fuse_fs_flock to fuse_versionscript
+
+2012-04-10  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Check protocol version before sending notifications and return
+	-ENOSYS if a particular notification is not supported.
+
+	* Add 'flag_utime_omit_ok' flag to fuse_operations.  If the
+	filesystem sets this flag then ->utimens() will receive UTIME_OMIT
+	and UTIME_NOW values as specified in utimensat(2).
+
+2012-01-27  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Interpret octal escape codes in options.  Requested by Jan
+	Engelhardt
+
+2012-01-26  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Add man pages for fusermount, mount.fuse and ulockmgr_server.
+	Lifted from the Debian package.  The man pages were written by
+	Daniel Baumann and Bastien Roucaries
+
+2012-01-13  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Disable symbol versions on MacOSX.  Patch by Anatol Pomozov
+
+2012-01-02  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Remove unnecessary mutex unlock at the end of multithreaded
+	event loop.
+
+2011-12-09  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fix hang in wait_on_path().  Reported by Ville Silventoinen
+
+	* Don't unhash name in FORGET.  This resulted in ENOENT being
+	returned for unlinked but still open files if the kernel sent a
+	FORGET request for the parent directory.
+
+	* Free request in fuse_reply_data().
+
+2011-12-08  Miklos Szeredi <miklos@szeredi.hu>

+	file or directory is deleted.  Patch by John Muir
+
+2011-12-06  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Update retrieve_reply() method
+
+2011-12-05  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Low level API: lock argument of fuse_reply_lock should have a
+	'const' qualifier.  Reported by Shachar Sharon
+
+	* Add support for ioctl on directories.  Reported by Antonio SJ
+	Musumeci
+
+2011-10-13  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Reply to request with ENOMEM in case of failure to allocate
+	request structure.  Otherwise the task issuing the request will
+	just freeze up until the filesystem daemon is killed.  Reported by
+	Stephan Kulow
+
+2011-09-23  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Replace daemon() function with fork().  Patch by Anatol Pomozov
+
+2011-08-26  Miklos Szeredi <miklos@szeredi.hu>
+
+	* If configured with --disable-mtab then don't call mount(8) from
+	libfuse to update the mtab.  Reported by: James Sierp
+
+2011-08-24  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Use LRU list for cleaning up the cache if the "remember=T"
+	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.
+
+	* libfuse: add retrieve request.  Retrieve data stored in the
+	kernel buffers for a given inode.
+
+2010-10-14  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Use LTLIBICONV when linking libfuse.  This fixes building against
+	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
+	growing list of ulockmgr_server processes with an endless list of
+	open files which finally exceeds the open file handle limit.
+	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
+	need not be calculated for the following operations: read, write,
+	flush, release, fsync, readdir, releasedir, fsyncdir, ftruncate,
+	fgetattr, lock, ioctl and poll.
+
+2010-05-10  Miklos Szeredi <miklos@szeredi.hu>

+2010-02-01  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Using "--no-canonicalize" with umount(8) conflicts with the race
+	fix, sinceit assumes the supplied path is absolute, while the race
+	fix relies on the path being relative to the current directory.
+	Reported by Tom Rindborg
+

+
+	* Released 2.8.2

+
+	* Fix race if two "fusermount -u" instances are run in parallel.
+	Reported by Dan Rosenberg
+
+	* Make sure that the path to be unmounted doesn't refer to a
+	symlink
+
+2010-01-14  Miklos Szeredi <miklos@szeredi.hu>
+
+	* 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.
+
+2009-09-11  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Released 2.8.1
+
+2009-08-25  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fix missing versioned symbol fuse_get_context@FUSE_2.2
+
+2009-08-18  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Released 2.8.0
+
+2009-08-18  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Add missing fuse_session_data to versionscript
+
+	* Make sure all global symbols are prefixed with "fuse_" or "cuse_"
+
+2009-07-16  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Clarify how the protocol version should be negotiated between
+	kernel and userspace.  Notably libfuse didn't correctly handle the
+	case when the supported major versions didn't match
+
+	* 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.
+
+2009-06-16  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Add missing fuse_reply_bmap to versionscript.  Debian
+	Bug#531329.  Reported by Goswin Brederlow
+
+2009-05-27  Miklos Szeredi <miklos@szeredi.hu>

+
+	* Only pass valid flags to ->setattr().
+
+2008-12-05  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Implement ioctl support.  On high level interface only
+	"restricted" ioctls are supported (which are defined with the
+	_IO(), _IOR(), _IOW() or _IOWR() macros).  Unrestricted ioctls
+	will only be allwed to CUSE (Character Device in Userspace)
+	servers.  Patch by Tejun Heo
+
+2008-11-28  Miklos Szeredi <miklos@szeredi.hu>
+
+	* If open sets fi->nonseekable, libfuse will tell the kernel that

+
+2008-11-19  Miklos Szeredi <miklos@szeredi.hu>

+	mounted from /etc/fstab or via mount(8).  Reported by Jan Ondrej.
+
+	* Skip calling mount(8) if /etc/mtab doesn't exist or if it's on a

+2008-05-09  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Don't allow bigger than 4kB writes by default on 2.6.26 and
+	later kernels, so that filesystems not expecting this are not
+	broken on a kernel upgrade.  Provide a 'big_writes' mount option
+	to enable this feature.  In future API revisions this may become

+
+	* Only enable cancelation when reading a request, otherwise
+	cancellation could happen with a mutex held, which could hang the
+	process on umount
+
+2008-02-08  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Block SIGCHLD when executing mount and umount
+
+	* fusexmp_fh: avoid unnecessary seeking in readdir
+
+	* Update kernel interface to 7.9:
+
+	* Support receiving file handle from kernel in GETATTR request
+
+	* Allow operations with a NULL path argument, if the filesystem
+	supports it
+
+	* Add support atomic open(O_TRUNC)
+
+	* Support the st_blksize field in struct stat
+
+	* If the "FUSE_THREAD_STACK" environment is set, initialize the
+	stack size of threads by this value.  Patch by Florin Malita
+
+	* Add per-node locking, instead of a global tree lock to protect
+	the path from changing during operations.  Original patch by
+	Rodrigo Castro
+
+2008-02-03  Csaba Henk <csaba.henk@creo.hu>
+
+	* lib/mount_bsd.c:
+	- string formatting fixes
+	- exit if mounting has failed
+	  (in FreeBSD a mount failure is not critical per se, as the daemon
+	  still could be mounted externally, but waiting for such an event
+	  is more confusing than fruitful)
+	- ditch the kvm(8) stuff and simply use forced unmount which just
+	  won't block
+	- prettify option specifications
+	- add "-onosync_unmount" kernel option
+
+2008-01-07  Csaba Henk <csaba.henk@creo.hu>
+
+	* lib/mount_bsd.c:
+	- refine device closing in a race-free way
+	- add support for "-osubtype" on FreeBSD
+
+	* makeconf.sh: make it work under FreeBSD
+
+2008-01-03  Csaba Henk <csaba.henk@creo.hu>
+
+	* lib/mount_bsd.c: close device before unmount
+	(cf. lib/mount.c rev. 1.43) and fix some warnings 
+
+2007-12-23  Miklos Szeredi <miklos@szeredi.hu>

+2007-12-12  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fix kernel module compile for 2.6.24
+
+	* Invalidate attributes of parent directory after create(), since
+	the modification time changes.  Invalidate attributes on rename,
+	since some filesystems may update st_ctime.  Reported by Szabolcs
+	Szakacsits
+
+	* Fix NFS exporting to handle 64bit node IDs
+
+	* Disable old symbol versions if __UCLIBC__ is defined.  If a
+	symbol in a library has multiple versions, the runtime linker in
+	uClibc seems to randomly choose between them.
+
+	* Remove erroneous 'fuse_opt_insert_arg@FUSE_2_5' from
+	fuse_version_script.  fuse_opt_free_args() was added in fuse-2.6.
+
+	* Close fuse device file descriptor before calling umount(),
+	preventing a deadlock when umount is synchronous.  Reported by
+	Szabolcs Szakacsits
+
+2007-11-12  Miklos Szeredi <miklos@szeredi.hu>
+
+	* 'fusermount -u' did not umount the filesystem if /etc/mtab was a

+
+	* Don't call /bin/[u]mount if /etc/mtab is a symlink.  Reported by

+
+	* Released 2.7.0
+
+2007-07-02  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Accept a NULL "op" for fuse_main(), etc.  This is useful if

+2007-05-29  Miklos Szeredi <miklos@szeredi.hu>
+
+	* lib: optimization: store parent pointer in node instead of
+	parent id
+
+2007-05-25  Miklos Szeredi <miklos@szeredi.hu>
+
+	* lib: don't create new thread for each FORGET request.  FORGET

+
+2007-05-24  Miklos Szeredi <miklos@szeredi.hu>

+	event loop.  Found by Chris AtLee
+
+2007-05-23  Miklos Szeredi <miklos@szeredi.hu>
+
+	* lowlevel lib: add fuse_reply_iov function, which is similar to

+	Willcocks
+
+2007-05-21  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fix Oops or error if a regular file is created with mknod(2) on

+
+2007-05-11  Csaba Henk <csaba.henk@creo.hu>

+	possible
+
+	* Clean up init script, make it LSB compliant
+
+2007-04-26  Miklos Szeredi <miklos@szeredi.hu>
+
+	* In multithreaded loop, use a semaphore instead of SIGHUP to wake
+	up the main thread on umount.  This is more elegant, and works
+	even if signals are blocked.
+
+2007-04-25  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Improve mounting support in libfuse:
+	 - check non-empty mountpoint
+	 - only fall back to fusermount when necessary
+
+2007-04-23  Miklos Szeredi <miklos@szeredi.hu>

+2007-02-05  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fix 2.6.9 RHEL kernels, which have compatibility mutex.h, but

+
+2007-02-04  Miklos Szeredi <miklos@szeredi.hu>

+	Szabolcs
+
+2007-02-03  Miklos Szeredi <miklos@szeredi.hu>

+	* lib: Fix use after free in fuse_flush().  Reported by Ron
+	Lindman
+
+2006-12-10  Miklos Szeredi <miklos@szeredi.hu>
+
+	* 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
+	between fusermount and mount trying to modify /etc/mtab at the

+
+	* Fix "buffer size too small: 4" warning for users of the
+	fuse_loop_mt_proc() function.
+
+2006-12-04  Miklos Szeredi <miklos@szeredi.hu>

+2006-11-29  Miklos Szeredi <miklos@szeredi.hu>
+

+
+	* kernel: fix build problem for "make -C ...".  Reported by
+	Stephen Bryant
+
+2006-11-19  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fix bug in certain error paths of lookup routines.  The request
+	object was reused for sending FORGET, which is illegal.  This bug
+	could cause an Oops in linux-2.6.18 or in fuse-2.6.0, and might
+	silently corrupt memory in earlier versions.  Report and test
+	program by Russ Cox
+
+2006-11-11  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Print an error if an incompatible kernel interface version is
+	detected in INIT.  This will only show if filesystem is started
+	with -d or -f
+
+	* Fix order of fuse_destroy()/fuse_unmount() in error cleanup of
+	fuse_setup_common().  Reported by Szakacsits Szabolcs
+
+2006-11-06  Miklos Szeredi <miklos@szeredi.hu>

+2006-10-26  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fix mount.fuse to use /bin/sh instead of /bin/bash, which is not
+	always available on embedded systems.  Patch from Paul Smith
+
+	* Fix util/Makefile.am, so that failure to run update-rc.d or
+	device creation doesn't cause make to fail.  Reported by Paul
+	Smith
+
+2006-10-21  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Released 2.6.0
+
+2006-10-18  Miklos Szeredi <miklos@szeredi.hu>
+

+
+2006-10-17  Miklos Szeredi <miklos@szeredi.hu>

+
+	* kernel: cleanups
+
+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
+
+2006-09-24  Csaba Henk <csaba.henk@creo.hu>
+
+	* Add support for nanosec times on FreeBSD
+
+	* Fix FreeBSD compatibility issues
+
+2006-09-23  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
+
+2006-06-29  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Support in kernel module for file locking and interruption.  The
+	same functionality is available in official kernels >= 2.6.18
+
+2006-06-28  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Add POSIX file locking support
+
+	* Add request interruption
+
+2006-06-06  Miklos Szeredi <miklos@szeredi.hu>
+
+	* 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>
+
+	* lib: Let FreeBSD mount option parsing routine recognize "no"
+	prefixes for FUSE specific options as well
+
+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
+
+2006-03-10  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fix source compatibility breakage for fuse_unmount().  Report
+	from Yura Pakhuchiy
+
+2006-03-02  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fix O_ASYNC handling in fuse_dev_release().  From Jeff Dike
+
+2006-03-01  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Add O_ASYNC and O_NONBLOCK support to FUSE device.  Patch by
+	Jeff Dike
+
+	* Renamed fuse_chan_receive() to fuse_chan_recv() and changed
+	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>
+
+	* libfuse: fix use-after-free bug in interruptred reply_entry().
+	Patch from John Muir
+
+	* libfuse: fix wrong symbol versioning for fuse_mount.  Debian bug
+	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>
+
+	* Refine clock_gettime() querying so that linker options
+	shall be set as it's appropriate for the target platform.
+
+2006-02-09  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fix udev rule syntax.  Reported by Nix
+
+2006-02-08  Miklos Szeredi <miklos@szeredi.hu>
+
+	* In some cases udev rule seems to be ineffective when installed
+	as 40-fuse.rules but work as 60-fuse.rules.  Reported by John Hunt
+
+2006-02-03  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fix compilation when build directory is different from source
+	directory.  Reported by Frédéric L. W. Meunier
+
+2006-02-02  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fix even bigger bug introduced in fix for request_end() on
+	2006-01-14.  Reported by Gal Rosen
+
+2006-01-30  Miklos Szeredi <miklos@szeredi.hu>
+
+	* highlevel-lib: add 'auto_cache' option.  This caches file data
+	based on modification time and size
+
+2006-01-20  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Sanitize storage type and help message in mount_bsd.c.  Patch
+	from Csaba Henk
+
+	* fuse_opt: add new helper constants FUSE_OPT_KEY_KEEP and
+	FUSE_OPT_KEY_DISCARD
+
+	* Add options 'max_readahead', 'sync_read' and 'async_read'
+
+	* Kernel ABI version 7.6:
+
+	* Negotiate the 'max_readahead' value and 'async_read' flags with
+	userspace in the INIT method
+
+	* Add connection info to ->init() methods to both lowlevel and
+	highlevel API
+
+	* Fall back to synchronous read() behavior if either library or
+	userspace filesystem is using the old interface version.  This is
+	needed so non-updated filesystems won't be confused by the
+	different read() behavior
+
+2006-01-19  Miklos Szeredi <miklos@szeredi.hu>
+
+	* lib: if "fsname=" option was given, pass it to fusermount
+
+	* 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
+	a regular file
+
+	* Add current output argument vector to option processing
+	function
+
+2005-12-12  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fix stale code in ifdef FreeBSD.  Patch from Csaba Henk
+
+2005-12-09  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Released 2.5.0-pre1
+
+2005-12-09  Miklos Szeredi <miklos@szeredi.hu>
+
+	* libfuse: added option parsing interface, defined in
+	<fuse_opt.h>.
+
+2005-12-07  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Return EIO for file operations (read, write, fsync, flush) on
+	open files whose inode has become "bad".  Inodes will be marked
+	"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
+	with > 4k page size, Bug report by Mark Haney
+
+	* ABI version 7.5:
+
+	* Extend INIT reply with data size limits
+
+2005-12-02  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fix memory leak in fuse_read_cmd()/fuse_process_cmd().  Bug
+	reported by Vincenzo Ciancia
+
+	* Handle exit-by-umount in fuse_read_cmd()
+
+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
+
+2005-11-17  Miklos Szeredi <miklos@szeredi.hu>
+
+	* 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
+	arguments
+
+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
+	Henk.
+
+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>

+2005-09-26  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Released 2.4.0-rc1
+
+2005-09-26  Miklos Szeredi <miklos@szeredi.hu>
+
+	* fusermount: allow user umount in the case when /etc/mtab is a
+	symlink to /proc/mounts.  Reported by Balázs Pozsár.
+
+2005-09-23  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Check for special node ID values in lookup and creation
+
+2005-09-22  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Slight optimization in returning EINVAL error in case of an open
+	with O_DIRECT flag.
+
+2005-09-20  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Remove '--enable-auto-modprobe' configure flag.  Module
+	auto-loading is now handled by the kernel.
+
+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>
+
+	* Set umask to zero in fusexmp and fusexmp_fh, so that
+	files/directories are created with the requested mode.
+
+2005-09-12  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Don't ignore read error in multithreaded loop
+
+2005-09-08  Miklos Szeredi <miklos@szeredi.hu>
+
+	* 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>
+
+	* lib: always refresh directory contents after rewinddir() to
+	conform to SUS.  Bug found by John Muir.
+
+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
+	configurable through INSTALL_MOD_PATH and MOUNT_FUSE_PATH
+	environment variables.  Requirement and help from Csaba Henk.
+
+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
+	Usarin Heininga
+
+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
+
+2005-06-28  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Add 'mount.fuse' written by Petr Klima
+
+	* '/dev/fuse' is created by 'make install' if does not yet exist
+
+2005-06-20  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fix UCLIBC compile error.  Patch by Christian Magnusson
+
+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
+	is needed on certain architectures.  Report from Chris Kirby
+
+	* Fix buggy behavior of open(..., O_CREAT|O_EXCL) if interrupted.
+	Reported by David Shaw
+
+	* Remove "allow_root" option from kernel module, and implement
+	it's functionality in the library
+
+	* Fix Oops caused by premature release of fuse_conn.  Clean up
+	related code, to be more readable
+
+	* Sendfile should not use page cache if "direct_io" mount option
+	is given
+
+2005-04-08  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fix Oops in case of nfs export.  Spotted by David Shaw
+
+	* Fix another Oops in case of write over nfs with direct_io turned
+	on.  Again spotted by David Shaw
+
+2005-04-07  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Released 2.3-pre4
+
+2005-04-07  Miklos Szeredi <miklos@szeredi.hu>
+
+	* lib: finalized new readdir() interface, which now supersedes the
+	getdir() method.
+
+2005-04-03  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Released 2.3-pre3
+
+2005-04-03  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Implement backward compatibility with version 5 kernel ABI
+
+2005-04-01  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Released 2.3-pre2
+
+2005-04-01  Miklos Szeredi <miklos@szeredi.hu>
+
+	* kernel: fix dirent offset handling
+
+	* lib: add readdir and releasedir methods
+
+	* lib: use fh field of fuse_file_info in opendir, readdir,
+	releasedir and fsyncdir methods
+
+	* lib: check kernel API version and bail out of it's old.  This
+	will be properly fixed in the next release
+
+2005-03-31  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Released 2.3-pre1
+
+2005-03-31  Miklos Szeredi <miklos@szeredi.hu>
+
+	* kernel API: add padding to structures, so 64bit and 32bit
+	compiler will return the same size
+
+	* kernel API: add offset field to fuse_dirent.  This will allow
+	more sophisticated readdir interface for userspace
+
+	* kernel API: change major number to 6
+
+	* kernel: fix warnings on 64bit archs
+
+	* kernel: in case of API version mismatch, return ECONNREFUSED
+
+2005-03-24  Miklos Szeredi <miklos@szeredi.hu>
+
+	* kernel: trivial cleanups
+
+2005-03-21  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Add fsyncdir() operation
+
+2005-03-19  Miklos Szeredi <miklos@szeredi.hu>
+
+	* kernel: add locking to background list (fixes previous fix)
+
+2005-03-18  Miklos Szeredi <miklos@szeredi.hu>
+
+	* kernel: fix bug which could cause leave busy inodes after
+	unmount, and Oops.
+
+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>
+
+	* Cleaned up directory reading (temporary file is not used)
+
+2005-02-02  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Released 2.2
+
+2005-02-02  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fix possible race when operation is interrupted
+
+2005-01-28  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fix compilation on 2.6.7
+
+2005-01-26  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Released 2.2-pre6
+
+2005-01-26  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fix bug in link() operation which caused the wrong path to be
+	passed as the first argument.  Found by Anton Altaparmakov
+
+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>
+
+	* Add 'writepage' flag to 'fuse_file_info'.
+
+	* 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>
+
+	* kernel: clean up writing functions
+
+	* kernel: no allocation on write in direct_io mode
+

+
+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>
+
+	* Check kernel interface version in fusermount to prevent
+	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
+	the wrong order.  Bug spotted and endured for months by Franco
+	Broi, and logfile for solution provided by Terje Oseberg
+
+2004-09-01  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Add -D_REENTRANT to the compile flags
+
+	* 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
+
+	* Work with newer libtool (1.5a)
+
+	* Check for st_atim member of struct stat
+
+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
+	and fsync
+
+	* Don't call getdir method from open() only from first readdir().
+	Open is sometimes just used to store the current directory
+	(e.g. find)
+
+2004-05-18  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Added flush() call
+
+2004-05-04  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Extended attributes support for 2.4 (patch by Cody Pisto)
+
+2004-04-20  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fixed parser with modversions (Mattias Wadman)
+
+2004-04-19  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Added mount option parser to 2.4 build
+
+2004-04-13  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Replaced binary mount data with text options
+
+	* Show FUSE specific mount options in /proc/mounts
+
+	* Check in fuse.h whether _FILE_OFFSET_BITS is set to 64
+
+2004-04-09  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Check some limits so userspace won't get too big requests
+
+2004-04-05  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Kill compile warning
+
+	* Upgraded user-mount patch for 2.6.5
+
+2004-04-02  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Add detection of user-mode-linux to configure
+
+2004-03-31  Miklos Szeredi <miklos@szeredi.hu>
+
+	* fixed zero size case for getxattr and listxattr
+
+2004-03-30  Miklos Szeredi <miklos@szeredi.hu>
+
+	* new fusermount flag '-z': lazy unmount, default is not lazy
+
+	* Extended attributes operations added (getxattr, setxattr,
+	listxattr, removexattr)
+
+2004-03-25  Miklos Szeredi <miklos@szeredi.hu>
+
+	* If filesystem doesn't define a statfs operation, then an
+	all-zero default statfs is returned instead of ENOSYS
+
+2004-03-24  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Add FS_BINARY_MOUNTDATA filesystem flag for kernels > 2.6.4
+
+2004-03-09  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fix for uClinux (Christian Magnusson)
+
+2004-03-02  Miklos Szeredi <miklos@szeredi.hu>
+
+	* fuse_main() adds "-n progname" to the fusermount command line
+
+	* More kernel interface changes:
+
+	* Lookup/getattr return cache timeout values
+
+2004-02-25  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Clean up option parsing in fuse_main()
+
+	* Added fuse_get() function which returns the fuse object created
+	by fuse_main()
+
+2004-02-20  Miklos Szeredi <miklos@szeredi.hu>
+
+	* removed old way of mounting (fusermount mountpoint program)
+
+	* more kernel interface changes:
+
+	* added nanosecond precision to file times
+
+	* removed interface version from mount data
+
+	* added /proc/fs/fuse/version which contains MAJOR.MINOR
+
+2004-02-19  Miklos Szeredi <miklos@szeredi.hu>
+
+	* statfs library API changed to match other methods.  Since this
+	  is not backward compatible FUSE_MAJOR_VERSION is changed to 2
+
+	* kernel interface changes follow:
+
+	* statfs changed to 64 bits, added 'bavail' field
+
+	* add generation number to lookup result
+
+	* optimized mknod/mkdir/symlink/link (no separate lookup is
+	needed)
+
+	* rdev size increased to 32 bits for mknod
+
+	* kernel interface version changed to 3.1
+
+2004-02-18  Miklos Szeredi <miklos@szeredi.hu>
+
+	* user-mount upgraded for 2.6.3 kernel
+
+2004-02-17  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Added user-mount.2.6.2-rc3.patch
+
+	* Add FS_SAFE flag to fuse filesystem
+
+	* fusermount should allow (un)mounting for non-root even if not
+	suid-root
+
+2004-02-12  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Remove MS_PERMISSION mount flag (that means something else now)
+
+2004-02-10  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Added check for i_size_read/write functions to configure.in
+	(patch by Valient Gough)
+
+2004-02-06  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fixed writing >= 2G files
+
+	* Check file size on open (with generic_file_open())
+
+	* Readpage calls flush_dcache_page() after storing data
+
+	* Use i_size_read/write for accessing inode->i_size
+
+	* Make loopback mount of a fuse file work
+
+2004-02-04  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Released 1.1
+
+2004-01-29  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Properly check if the inode exists in fuse_invalidate
+
+2004-01-27  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Added -q option for fusermount
+
+	* fuse_unmount() now uses -q option of fusermount, so no error is
+	printed if the cause of the program exit is that the filesystem
+	has already been unmounted
+
+	* Fix i_nlink correctness after rmdir/unlink
+
+2004-01-26  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Released 1.1-pre2
+
+2004-01-26  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fix typo (thanks Marcos Dione)
+
+	* Compile fixes for 2.4 kernels
+
+2004-01-23  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fix CONFIG_MODVERSIONS compile on 2.6
+
+2004-01-22  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Write all pending data before a RELEASE operation
+
+	* Suppress 'Bad file descriptor' warning on exit
+
+	* Replaced fusermount option '-d xxx' with '-n xxx' so it doesn't
+	get confused with '-d' of fuse_main() (sorry about this change)
+
+	* New fusermount option '-l' which enables big reads.  Big reads
+	are now disabled by default.
+
+	* fuse_main() can accept fusermount arguments after a '--'
+
+2004-01-19  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Support for exporting filesystem over NFS (see README.NFS)
+
+2004-01-14  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Support non-blocking writepage on 2.6.  This makes FUSE behave
+	much more nicely in low-memory situations
+
+	* Fix 32-bit dev handling in getattr and mknod for 2.6 kernels.
+	(Note: the mknod method does not yet use 32bit device number)
+
+2004-01-13  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Code cleanups
+
+2004-01-07  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Released 1.1-pre1
+
+2004-01-06  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Integrated 2.6 kernel support patch by Michael Grigoriev
+
+	* Improvements and cleanups for 2.6 kernels
+
+2004-01-05  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Added -d option to fusermount
+
+2003-12-15  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Added major+minor version to library API, and minor version to
+	  kernel API
+
+2003-12-13  David McNab <david@rebirthing.co.nz>
+
+	* Implemented fsync support in examples/example.py
+
+	* Implemented 'fsync' and 'statfs' methods in python
+	  interface
+
+2003-12-12  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Make it compile on 2.4.19.
+
+	* Add fsync operation (write file failed on xemacs & vi)
+
+2003-12-12  David McNab <david@rebirthing.co.nz>
+
+	* Added distutils support to the python module, as per standard
+	  python development practice
+
+2003-12-11  Miklos Szeredi <miklos@szeredi.hu>
+
+	* 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

+                  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.

+What is new in 2.9
+
+ - Add "zero copy" support for kernel 2.6.35 or newer
+
+ - Make maximum background requests tunable on kernel 2.6.32 or newer
+
+ - Require --no-canonicalize in (u)mount (util-linux version 2.18 or
+   newer) to fix security problems with fusermount
+
+ - Use dynamically sized hash tables in high level library
+
+ - Memory use of filesystem daemon can shrink more easily
+
+ - Add "auto_unmount" option
+
+ - Add "remember" option
+
+ - Add man pages for fusermount, mount.fuse and ulockmgr_server
+
+ - API changes:
+
+    o Introduce "store" and "retrieve" for accessing kernel buffers on
+      kernel 2.6.36 or newer
+
+    o Introduce abstract buffer for zero copy operations
+
+    o Allow path calculation to be omitted on certain operations
+
+    o Allow batching forget requests
+
+    o Add "flock" method
+
+    o Add support for ioctl on directories
+
+    o Add delete notification
+
+    o Add fallocate operation (linux kernel 3.5 or newer)
+
+ - Bug fixes and small improvements
+
+============================================================================
+
+What is new in 2.8
+
+ - More scalable directory tree locking
+
+ - Atomic open(O_TRUNC) support
+
+ - Support big write requests on kernels 2.6.26 and newer
+
+ - Out-of-tree fuse module removed
+
+ - Better NFS exporting support
+
+ - New ioctl and poll requests
+
+ - New CUSE (Character Device in Userspace) interface
+
+ - Allow umask processing in userspace
+
+ - Added cache invalidation notifications
+
+ - Bugfixes and small improvements
+
+============================================================================
+
+What is new in 2.7
+
+ - Stacking support for the high level API
+
+ - Add filename charset conversion module
+
+ - Improved mounting
+
+============================================================================
+
+What is new in 2.6
+
+ - Improved read characteristics (asynchronous reads)
+
+ - Support for aborting filesystem connection
+
+ - POSIX file locking support
+
+ - Request interruption support
+
+ - Building module for Linux kernels earlier than 2.6.9 not supported
+
+ - Allow block device based filesystems to support swap files
+
+ - Several bugs fixed, including a rare system hang on SMP
+
+============================================================================
+
+What is new in 2.5
+
+ - Merge library part of FreeBSD port
+
+ - New atomic create+open, access and ftruncate operations
+
+ - On filesystems implementing the new create+open operation, and
+   running on Linux kernels 2.6.15 or later, the 'cp' operation will
+   work correctly when copying read-only files.
+
+ - New option parsing interface added to the library
+
+ - Lots of minor improvements and fixes
+
+============================================================================
+
+What is new in 2.4
+
+ - Simplify device opening.  Now '/dev/fuse' is a requirement
+
+ - Allow module auto-loading if user has access to '/dev/fuse'
+
+ - Allow mounting over a regular file for unprivileged users
+
+ - Allow mounting of arbitrary FUSE filesystems from /etc/fstab
+
+ - New mount options: 'umask=M', 'uid=N', 'gid=N'
+
+ - Check for non-empty mountpoint, and refuse mount by default.  New
+   mount option: 'nonempty'
+
+ - Low level (inode based) API added
+
+ - Allow 'direct_io' and 'keep_cache' options to be set on a
+   case-by-case basis on open.
+
+ - Add 'attr_timeout' and 'entry_timeout' mount options to the
+   high-level library.  Until now these timeouts were fixed at 1 sec.
+
+ - Some bugfixes
+
+============================================================================
+
+What is new in 2.3
+
+ - Add new directory related operations: opendir(), readdir(),
+   releasedir() and fsyncdir()
+
+ - Add init() and destroy() operations which are called before the
+   event loop is started and after it has exited
+
+ - Update kernel ABI so that on dual architectures (e.g. AMD64) 32bit
+   binaries work under a 64bit kernel
+
+ - Bugfixes
+
+============================================================================
+
+What is new in 2.2
+
+Userspace changes:
+
+ - Add fuse_file_info structure to file operations, this allows the
+   filesystem to return a file handle in open() which is passed to
+   read(), write(), flush(), fsync() and release().
+
+ - Add source compatibility with 2.1 and 1.4 releases
+
+ - Binary compatibility with 2.1 release is retained
+
+Kernel changes:
+
+ - Make requests interruptible.  This prevents the filesystem to go
+   into an unbreakable deadlock with itself.
+
+ - Make readpages() synchronous.  Asynchronous requests are deadlock
+   prone, since they cannot be interrupted (see above)
+
+ - Remove shared-writeable mapping support, which could deadlock the
+   machine
+
+ - Remove INVALIDATE userspace initiated request
+
+ - Update ABI to be independent of sizeof(long), so dual-size archs
+   don't cause problems
+
+ - Remove /sys/fs/fuse/version.  Version checking is now done through
+   the fuse device
+
+ - Replace directory reading method on the kernel interface.  Instead
+   of passing an open file descriptor to the kernel, send data through
+   the FUSE device, like all other operations.
+
+============================================================================
+
+What is new in 2.1
+
+* Bug fixes

+NFS exporting is supported in Linux kernels 2.6.27 or later.
+
+You need to add an fsid=NNN option to /etc/exports to make exporting a
+FUSE directory work.
+
+Filesystem support
+------------------
+
+NFS exporting works to some extent on all fuse filesystems, but not
+perfectly.  This is due to the stateless nature of the protocol, the
+server has no way of knowing whether the client is keeping a reference
+to a file or not, and hence that file may be removed from the server's
+cache.  In that case there has to be a way to look up that object
+using the inode number, otherwise an ESTALE error will be returned.
+
+1) low-level interface
+
+Filesystems need to implement special lookups for the names "." and
+"..".  The former may be requested on any inode, including
+non-directories, while the latter is only requested for directories.
+Otherwise these special lookups should behave identically to ordinary
+lookups.
+
+2) high-level interface
+
+Because the high-level interface is path based, it is not possible to
+delegate looking up by inode to the filesystem.
+
+To work around this, currently a "noforget" option is provided, which
+makes the library remember nodes forever.  This will make the NFS
+server happy, but also results in an ever growing memory footprint for
+the filesystem.  For this reason if the filesystem is large (or the
+memory is small), then this option is not recommended.

+Warning: unresolved security issue
+----------------------------------
+
+Be aware that FUSE has an unresolved security bug
+([bug #15](https://github.com/libfuse/libfuse/issues/15)): the
+permission check for accessing a cached directory is only done once
+when the directory entry is first loaded into the cache. Subsequent
+accesses will re-use the results of the first check, even if the
+directory permissions have since changed, and even if the subsequent
+access is made by a different user.
+
+This bug needs to be fixed in the Linux kernel and has been known
+since 2006 but unfortunately no fix has been applied yet. If you
+depend on correct permission handling for FUSE file systems, the only
+workaround is to completely disable caching of directory
+entries. Alternatively, the severity of the bug can be somewhat
+reduced by not using the `allow_other` mount option.
+
+
+About
+-----
+
+FUSE (Filesystem in Userspace) is an interface for userspace programs
+to export a filesystem to the Linux kernel. The FUSE project consists
+of two components: the *fuse* kernel module (maintained in the regular
+kernel repositories) and the *libfuse* userspace library (maintained
+in this repository). libfuse provides the reference implementation
+for communicating with the FUSE kernel module.
+
+A FUSE file system is typically implemented as a standalone
+application that links with libfuse. libfuse provides functions to
+mount the file system, unmount it, read requests from the kernel, and
+send responses back. libfuse offers two APIs: a "high-level",
+synchronous API, and a "low-level" asynchronous API. In both cases,
+incoming requests from the kernel are passed to the main program using
+callbacks. When using the high-level API, the callbacks may work with
+file names and paths instead of inodes, and processing of a request
+finishes when the callback function returns. When using the low-level
+API, the callbacks must work with inodes and responses must be sent
+explicitly using a separate set of API functions.
+
+
+Installation
+------------
+
+    ./configure
+    make -j8
+    make install
+
+You may also need to add `/usr/local/lib` to `/etc/ld.so.conf` and/or
+run *ldconfig*. If you're building from the git repository (instead of
+using a release tarball), you also need to run `./makeconf.sh` to
+create the `configure` script.
+
+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`
+
+Security implications
+---------------------
+
+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 (though this can be relaxed by allowing the use
+    of the `allow_other` and `allow_root` mount options in `fuse.conf`)
+
+
+Building your own filesystem
+------------------------------
+
+FUSE comes with several example file systems in the `examples`
+directory. For example, the *fusexmp* example mirrors the contents of
+the root directory under the mountpoint. Start from there and adapt
+the code!
+
+The documentation of the API functions and necessary callbacks is
+mostly contained in the files `include/fuse.h` (for the high-level
+API) and `include/fuse_lowlevel.h` (for the low-level API). An
+autogenerated html version of the API is available in the `doc/html`
+directory and at http://libfuse.github.io/doxygen.
+

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to '$srcdir/foo'.  In other projects, it is set to
+# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory.  The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run.  This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+#    fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+#    fails if $ac_aux_dir is absolute,
+#    fails when called from a subdirectory in a VPATH build with
+#          a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir.  In an in-source build this is usually
+# harmless because $srcdir is '.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
+#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+#   MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an
+# absolute PATH.  The drawback is that using absolute paths prevent a

+\`configure' configures fuse 2.9.7 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking ...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+  --prefix=PREFIX         install architecture-independent files in PREFIX
+                          [$ac_default_prefix]
+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:

+
+Some influential environment variables:
+  CC          C compiler command
+  CFLAGS      C compiler flags
+  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
+              nonstandard directory <lib dir>
+  LIBS        libraries to pass to the linker, e.g. -l<library>
+  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
+              you have headers in a nonstandard directory <include dir>
+  CPP         C preprocessor
+
+Use these variables to override the choices made by `configure' or to help

+## dummy dependencies for each header file.  Too bad gcc doesn't do
+## this for us directly.
+## Some versions of gcc put a space before the ':'.  On the theory

+                           How Fuse-1.3 Works
+
+[Written by Terje Oseberg]
+
+1. The fuse library.
+
+When your user mode program calls fuse_main() (lib/helper.c),
+fuse_main() parses the arguments passed to your user mode program,
+then calls fuse_mount() (lib/mount.c).
+
+fuse_mount() creates a UNIX domain socket pair, then forks and execs
+fusermount (util/fusermount.c) passing it one end of the socket in the
+FUSE_COMMFD_ENV environment variable.
+
+fusermount (util/fusermount.c) makes sure that the fuse module is
+loaded. fusermount then open /dev/fuse and send the file handle over a
+UNIX domain socket back to fuse_mount().
+
+fuse_mount() returns the filehandle for /dev/fuse to fuse_main().
+
+fuse_main() calls fuse_new() (lib/fuse.c) which allocates the struct
+fuse datastructure that stores and maintains a cached image of the
+filesystem data.
+
+Lastly, fuse_main() calls either fuse_loop() (lib/fuse.c) or
+fuse_loop_mt() (lib/fuse_mt.c) which both start to read the filesystem
+system calls from the /dev/fuse, call the usermode functions
+stored in struct fuse_operations datastructure before calling
+fuse_main(). The results of those calls are then written back to the
+/dev/fuse file where they can be forwarded back to the system
+calls.
+
+2. The kernel module.
+
+The kernel module consists of two parts. First the proc filesystem
+component in kernel/dev.c -and second the filesystem system calls
+kernel/file.c, kernel/inode.c, and kernel/dir.c
+
+All the system calls in kernel/file.c, kernel/inode.c, and
+kernel/dir.c make calls to either request_send(),
+request_send_noreply(), or request_send_nonblock(). Most of the calls
+(all but 2) are to request_send(). request_send() adds the request to,
+"list of requests" structure (fc->pending), then waits for a response.
+request_send_noreply() and request_send_nonblock() are both similar in
+function to request_send() except that one is non-blocking, and the
+other does not respond with a reply.
+
+The proc filesystem component in kernel/dev.c responds to file io
+requests to the file /dev/fuse. fuse_dev_read() handles the
+file reads and returns commands from the "list of requests" structure
+to the calling program. fuse_dev_write() handles file writes and takes
+the data written and places them into the req->out datastructure where
+they can be returned to the system call through the "list of requests"
+structure and request_send().

+<div class="textblock"><p>Low level filesystem operations</p>
+<p>Most of the methods (with the exception of init and destroy) receive a request handle (fuse_req_t) as their first argument. This handle must be passed to one of the specified reply functions.</p>
+<p>This may be done inside the method invocation, or after the call has returned. The request handle is valid until one of the reply functions is called.</p>
+<p>Other pointer arguments (name, <a class="el" href="structfuse__file__info.html">fuse_file_info</a>, etc) are not valid after the call has returned, so if they are needed later, their contents have to be copied.</p>
+<p>The filesystem sometimes needs to handle a return value of -ENOENT from the reply function, which means, that the request was interrupted, and the reply discarded. For example if <a class="el" href="fuse__lowlevel_8h.html#a170f8c6b953d70928e83bcecee43bfdc">fuse_reply_open()</a> return -ENOENT means, that the release method for this file will not be called. </p>

+<p>Inodes with a non-zero lookup count may receive request from the kernel even after calls to unlink, rmdir or (when overwriting an existing file) rename. Filesystems must handle such requests properly and it is recommended to defer removal of the inode until the lookup count reaches zero. Calls to unlink, remdir or rename will be followed closely by forget unless the file or directory is open, in which case the kernel issues forget only after the release or releasedir calls.</p>

+<div class="textblock"><p>The file system operations:</p>
+<p>Most of these should work very similarly to the well known UNIX file system operations. A major exception is that instead of returning an error in 'errno', the operation should return the negated error value (-errno) directly.</p>
+<p>All methods are optional, but some are essential for a useful filesystem (e.g. getattr). Open, flush, release, fsync, opendir, releasedir, fsyncdir, access, create, ftruncate, fgetattr, lock, init and destroy are special purpose methods, without which a full featured filesystem can still be implemented.</p>
+<p>Almost all operations take a path which can be of any length.</p>
+<p>Changed in fuse 2.8.0 (regardless of API version) Previously, paths were limited to a length of PATH_MAX.</p>
+<p>See <a href="http://fuse.sourceforge.net/wiki/">http://fuse.sourceforge.net/wiki/</a> for more information. There is also a snapshot of the relevant wiki pages in the doc/ folder. </p>

+<p>Flush is called on each close() of a file descriptor. So if a filesystem wants to return write errors in close() and the file has cached dirty data, this is a good place to write back data and return any errors. Since many applications ignore close() errors this is not always useful.</p>
+<p>NOTE: The <a class="el" href="structfuse__operations.html#ad4ec9c309072a92dd82ddb20efa4ab14">flush()</a> method may be called more than once for each <a class="el" href="structfuse__operations.html#a14b98c3f7ab97cc2ef8f9b1d9dc0709d">open()</a>. This happens if more than one file descriptor refers to an opened file due to dup(), dup2() or fork() calls. It is not possible to determine if a flush is final, so each flush should be treated equally. Multiple write-flush sequences are relatively rare, so this shouldn't be a problem.</p>
+<p>Filesystems shouldn't assume that flush will always be called after some writes, or that if will be called at all.</p>

+<p>For checking lock ownership, the 'fuse_file_info-&gt;owner' argument must be used.</p>
+<p>For F_GETLK operation, the library will first check currently held locks, and if a conflicting lock is found it will return information without calling this method. This ensures, that for local locks the l_pid field is correctly filled in. The results may not be accurate in case of race conditions and in the presence of hard links, but it's unlikely that an application would rely on accurate GETLK results in these cases. If a conflicting lock is not found, this method will be called, and the filesystem may fill out l_pid by a meaningful value, or it may leave this field zero.</p>
+<p>For F_SETLK and F_SETLKW the l_pid field will be set to the pid of the process performing the locking operation.</p>
+<p>Note: if this method is not implemented, the kernel will still allow file locking to work locally. Hence it is only interesting for network filesystems and similar.</p>

+<div class="textblock"><p>Option description</p>
+<p>This structure describes a single option, and action associated with it, in case it matches.</p>
+<p>More than one such match may occur, in which case the action for each match is executed.</p>
+<p>There are three possible actions in case of a match:</p>
+<p>i) An integer (int or unsigned) variable determined by 'offset' is set to 'value'</p>
+<p>ii) The processing function is called, with 'value' as the key</p>
+<p>iii) An integer (any) or string (char *) variable determined by 'offset' is set to the value of an option parameter</p>
+<p>'offset' should normally be either set to</p>
+<ul>
+<li>'offsetof(struct foo, member)' actions i) and iii)</li>
+<li>-1 action ii)</li>
+</ul>
+<p>The 'offsetof()' macro is defined in the &lt;stddef.h&gt; header.</p>
+<p>The template determines which options match, and also have an effect on the action. Normally the action is either i) or ii), but if a format is present in the template, then action iii) is performed.</p>
+<p>The types of templates are:</p>
+<p>1) "-x", "-foo", "--foo", "--foo-bar", etc. These match only themselves. Invalid values are "--" and anything beginning with "-o"</p>
+<p>2) "foo", "foo-bar", etc. These match "-ofoo", "-ofoo-bar" or the relevant option in a comma separated option list</p>
+<p>3) "bar=", "--foo=", etc. These are variations of 1) and 2) which have a parameter</p>
+<p>4) "bar=%s", "--foo=%lu", etc. Same matching as above but perform action iii).</p>
+<p>5) "-x ", etc. Matches either "-xparam" or "-x param" as two separate arguments</p>
+<p>6) "-x %s", etc. Combination of 4) and 5)</p>
+<p>If the format is "%s", memory is allocated for the string unlike with scanf(). </p>

+Definitions
+~~~~~~~~~~~
+
+Userspace filesystem:
+
+  A filesystem in which data and metadata are provided by an ordinary
+  userspace process.  The filesystem can be accessed normally through
+  the kernel interface.
+
+Filesystem daemon:
+
+  The process(es) providing the data and metadata of the filesystem.
+
+Non-privileged mount (or user mount):
+
+  A userspace filesystem mounted by a non-privileged (non-root) user.
+  The filesystem daemon is running with the privileges of the mounting
+  user.  NOTE: this is not the same as mounts allowed with the "user"
+  option in /etc/fstab, which is not discussed here.
+
+Filesystem connection:
+
+  A connection between the filesystem daemon and the kernel.  The
+  connection exists until either the daemon dies, or the filesystem is
+  umounted.  Note that detaching (or lazy umounting) the filesystem
+  does _not_ break the connection, in this case it will exist until
+  the last reference to the filesystem is released.
+
+Mount owner:
+
+  The user who does the mounting.
+
+User:
+
+  The user who is performing filesystem operations.
+
+What is FUSE?
+~~~~~~~~~~~~~
+
+FUSE is a userspace filesystem framework.  It consists of a kernel
+module (fuse.ko), a userspace library (libfuse.*) and a mount utility
+(fusermount).
+
+One of the most important features of FUSE is allowing secure,
+non-privileged mounts.  This opens up new possibilities for the use of
+filesystems.  A good example is sshfs: a secure network filesystem
+using the sftp protocol.
+
+The userspace library and utilities are available from the FUSE
+homepage:
+
+  http://fuse.sourceforge.net/
+
+Filesystem type
+~~~~~~~~~~~~~~~
+
+The filesystem type given to mount(2) can be one of the following:
+
+'fuse'
+
+  This is the usual way to mount a FUSE filesystem.  The first
+  argument of the mount system call may contain an arbitrary string,
+  which is not interpreted by the kernel.
+
+'fuseblk'
+
+  The filesystem is block device based.  The first argument of the
+  mount system call is interpreted as the name of the device.
+
+Mount options
+~~~~~~~~~~~~~
+
+'fd=N'
+
+  The file descriptor to use for communication between the userspace
+  filesystem and the kernel.  The file descriptor must have been
+  obtained by opening the FUSE device ('/dev/fuse').
+
+'rootmode=M'
+
+  The file mode of the filesystem's root in octal representation.
+
+'user_id=N'
+
+  The numeric user id of the mount owner.
+
+'group_id=N'
+
+  The numeric group id of the mount owner.
+
+'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.  It 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.  This option is by default only
+  allowed to root, but this restriction can be removed with a
+  (userspace) configuration option.
+
+'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).
+
+'blksize=N'
+
+  Set the block size for the filesystem.  The default is 512.  This
+  option is only valid for 'fuseblk' type mounts.
+
+Control filesystem
+~~~~~~~~~~~~~~~~~~
+
+There's a control filesystem for FUSE, which can be mounted by:
+
+  mount -t fusectl none /sys/fs/fuse/connections
+
+Mounting it under the '/sys/fs/fuse/connections' directory makes it
+backwards compatible with earlier versions.
+
+Under the fuse control filesystem each connection has a directory
+named by a unique number.
+
+For each connection the following files exist within this directory:
+
+ 'waiting'
+
+  The number of requests which are waiting to be transferred to
+  userspace or being processed by the filesystem daemon.  If there is
+  no filesystem activity and 'waiting' is non-zero, then the
+  filesystem is hung or deadlocked.
+
+ 'abort'
+
+  Writing anything into this file will abort the filesystem
+  connection.  This means that all waiting requests will be aborted an
+  error returned for all aborted and new requests.
+
+Only the owner of the mount may read or write these files.
+
+Interrupting filesystem operations
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If a process issuing a FUSE filesystem request is interrupted, the
+following will happen:
+
+  1) If the request is not yet sent to userspace AND the signal is
+     fatal (SIGKILL or unhandled fatal signal), then the request is
+     dequeued and returns immediately.
+
+  2) If the request is not yet sent to userspace AND the signal is not
+     fatal, then an 'interrupted' flag is set for the request.  When
+     the request has been successfully transferred to userspace and
+     this flag is set, an INTERRUPT request is queued.
+
+  3) If the request is already sent to userspace, then an INTERRUPT
+     request is queued.
+
+INTERRUPT requests take precedence over other requests, so the
+userspace filesystem will receive queued INTERRUPTs before any others.
+
+The userspace filesystem may ignore the INTERRUPT requests entirely,
+or may honor them by sending a reply to the _original_ request, with
+the error set to EINTR.
+
+It is also possible that there's a race between processing the
+original request and it's INTERRUPT request.  There are two possibilities:
+
+  1) The INTERRUPT request is processed before the original request is
+     processed
+
+  2) The INTERRUPT request is processed after the original request has
+     been answered
+
+If the filesystem cannot find the original request, it should wait for
+some timeout and/or a number of new requests to arrive, after which it
+should reply to the INTERRUPT request with an EAGAIN error.  In case
+1) the INTERRUPT request will be requeued.  In case 2) the INTERRUPT
+reply will be ignored.
+
+Aborting a filesystem connection
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+It is possible to get into certain situations where the filesystem is
+not responding.  Reasons for this may be:
+
+  a) Broken userspace filesystem implementation
+
+  b) Network connection down
+
+  c) Accidental deadlock
+
+  d) Malicious deadlock
+
+(For more on c) and d) see later sections)
+
+In either of these cases it may be useful to abort the connection to
+the filesystem.  There are several ways to do this:
+
+  - Kill the filesystem daemon.  Works in case of a) and b)
+
+  - Kill the filesystem daemon and all users of the filesystem.  Works
+    in all cases except some malicious deadlocks
+
+  - Use forced umount (umount -f).  Works in all cases but only if
+    filesystem is still attached (it hasn't been lazy unmounted)
+
+  - Abort filesystem through the FUSE control filesystem.  Most
+    powerful method, always works.
+
+How do non-privileged mounts work?
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Since the mount() system call is a privileged operation, a helper
+program (fusermount) is needed, which is installed setuid root.
+
+The implication of providing non-privileged mounts is that the mount
+owner must not be able to use this capability to compromise the
+system.  Obvious requirements arising from this are:
+
+ A) mount owner should not be able to get elevated privileges with the
+    help of the mounted filesystem
+
+ B) mount owner should not get illegitimate access to information from
+    other users' and the super user's processes
+
+ C) mount owner should not be able to induce undesired behavior in
+    other users' or the super user's processes
+
+How are requirements fulfilled?
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+ A) The mount owner could gain elevated privileges by either:
+
+     1) creating a filesystem containing a device file, then opening
+	this device
+
+     2) creating a filesystem containing a suid or sgid application,
+	then executing this application
+
+    The solution is not to allow opening device files and ignore
+    setuid and setgid bits when executing programs.  To ensure this
+    fusermount always adds "nosuid" and "nodev" to the mount options
+    for non-privileged mounts.
+
+ B) If another user is accessing files or directories in the
+    filesystem, the filesystem daemon serving requests can record the
+    exact sequence and timing of operations performed.  This
+    information is otherwise inaccessible to the mount owner, so this
+    counts as an information leak.
+
+    The solution to this problem will be presented in point 2) of C).
+
+ C) There are several ways in which the mount owner can induce
+    undesired behavior in other users' processes, such as:
+
+     1) mounting a filesystem over a file or directory which the mount
+        owner could otherwise not be able to modify (or could only
+        make limited modifications).
+
+        This is solved in fusermount, by checking the access
+        permissions on the mountpoint and only allowing the mount if
+        the mount owner can do unlimited modification (has write
+        access to the mountpoint, and mountpoint is not a "sticky"
+        directory)
+
+     2) Even if 1) is solved the mount owner can change the behavior
+        of other users' processes.
+
+         i) It can slow down or indefinitely delay the execution of a
+           filesystem operation creating a DoS against the user or the
+           whole system.  For example a suid application locking a
+           system file, and then accessing a file on the mount owner's
+           filesystem could be stopped, and thus causing the system
+           file to be locked forever.
+
+         ii) It can present files or directories of unlimited length, or
+           directory structures of unlimited depth, possibly causing a
+           system process to eat up diskspace, memory or other
+           resources, again causing DoS.
+
+	The solution to this as well as B) is not to allow processes
+	to access the filesystem, which could otherwise not be
+	monitored or manipulated by the mount owner.  Since if the
+	mount owner can ptrace a process, it can do all of the above
+	without using a FUSE mount, the same criteria as used in
+	ptrace can be used to check if a process is allowed to access
+	the filesystem or not.
+
+	Note that the ptrace check is not strictly necessary to
+	prevent B/2/i, it is enough to check if mount owner has enough
+	privilege to send signal to the process accessing the
+	filesystem, since SIGSTOP can be used to get a similar effect.
+
+I think these limitations are unacceptable?
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If a sysadmin trusts the users enough, or can ensure through other
+measures, that system processes will never enter non-privileged
+mounts, it can relax the last limitation with a "user_allow_other"
+config option.  If this config option is set, the mounting user can
+add the "allow_other" mount option which disables the check for other
+users' processes.
+
+Kernel - userspace interface
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The following diagram shows how a filesystem operation (in this
+example unlink) is performed in FUSE.
+
+NOTE: everything in this description is greatly simplified

+ |  <sys_unlink()                     |
+
+There are a couple of ways in which to deadlock a FUSE filesystem.
+Since we are talking about unprivileged userspace programs,
+something must be done about these.
+
+Scenario 1 -  Simple deadlock
+-----------------------------
+
+ |  "rm /mnt/fuse/file"               |  FUSE filesystem daemon
+ |                                    |
+ |  >sys_unlink("/mnt/fuse/file")     |
+ |    [acquire inode semaphore        |
+ |     for "file"]                    |
+ |    >fuse_unlink()                  |
+ |      [sleep on req->waitq]         |
+ |                                    |  <sys_read()
+ |                                    |  >sys_unlink("/mnt/fuse/file")
+ |                                    |    [acquire inode semaphore
+ |                                    |     for "file"]
+ |                                    |    *DEADLOCK*
+
+The solution for this is to allow the filesystem to be aborted.
+
+Scenario 2 - Tricky deadlock
+----------------------------
+
+This one needs a carefully crafted filesystem.  It's a variation on
+the above, only the call back to the filesystem is not explicit,
+but is caused by a pagefault.
+
+ |  Kamikaze filesystem thread 1      |  Kamikaze filesystem thread 2
+ |                                    |
+ |  [fd = open("/mnt/fuse/file")]     |  [request served normally]
+ |  [mmap fd to 'addr']               |
+ |  [close fd]                        |  [FLUSH triggers 'magic' flag]
+ |  [read a byte from addr]           |
+ |    >do_page_fault()                |
+ |      [find or create page]         |
+ |      [lock page]                   |
+ |      >fuse_readpage()              |
+ |         [queue READ request]       |
+ |         [sleep on req->waitq]      |
+ |                                    |  [read request to buffer]
+ |                                    |  [create reply header before addr]
+ |                                    |  >sys_write(addr - headerlength)
+ |                                    |    >fuse_dev_write()
+ |                                    |      [look up req in fc->processing]
+ |                                    |      [remove from fc->processing]
+ |                                    |      [copy write buffer to req]
+ |                                    |        >do_page_fault()
+ |                                    |           [find or create page]
+ |                                    |           [lock page]
+ |                                    |           * DEADLOCK *
+
+Solution is basically the same as above.
+
+An additional problem is that while the write buffer is being copied
+to the request, the request must not be interrupted/aborted.  This is
+because the destination address of the copy may not be valid after the
+request has returned.
+
+This is solved with doing the copy atomically, and allowing abort
+while the page(s) belonging to the write buffer are faulted with
+get_user_pages().  The 'req->locked' flag indicates when the copy is
+taking place, and abort is delayed until this flag is unset.

+.SH NAME
+fuse \- format and options for the fuse file systems
+.SH DESCRIPTION
+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.
+.SH CONFIGURATION
+Some options regarding mount policy can be set in the file \fI/etc/fuse.conf\fP. Currently these options are:
+.TP
+\fBmount_max = NNN\fP
+Set the maximum number of FUSE mounts allowed to non-root users. The default is 1000.
+.TP
+\fBuser_allow_other\fP
+Allow non-root users to specify the \fBallow_other\fP or \fBallow_root\fP mount options (see below).
+.SH OPTIONS
+Most of the generic mount options described in \fBmount\fP are supported (\fBro\fP, \fBrw\fP, \fBsuid\fP, \fBnosuid\fP, \fBdev\fP, \fBnodev\fP, \fBexec\fP, \fBnoexec\fP, \fBatime\fP, \fBnoatime\fP, \fBsync\fP, \fBasync\fP, \fBdirsync\fP). Filesystems are mounted with \fBnodev,nosuid\fP by default, which can only be overridden by a privileged user.
+.SS "General mount options:"
+These are FUSE specific mount options that can be specified for all filesystems:
+.TP
+\fBdefault_permissions\fP
+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 \fBallow_other\fP mount option.
+.TP
+\fBallow_other\fP
+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.
+.TP
+\fBallow_root\fP
+This option is similar to \fBallow_other\fP but file access is limited to the user mounting the filesystem and root.  This option and \fBallow_other\fP are mutually exclusive.
+.TP
+\fBkernel_cache\fP
+This option disables flushing the cache of the file contents on every \fBopen\fP(2).  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 \fIintermediate\fP filesystems.
+
+\fBNOTE\fP: if this option is not specified (and neither \fBdirect_io\fP) data is still cached after the \fBopen\fP(2), so a \fBread\fP(2) system call will not always initiate a read operation.
+.TP
+\fBauto_cache\fP
+This option enables automatic flushing of the data cache on \fBopen\fP(2). The cache will only be flushed if the modification time or the size of the file has changed.
+.TP
+\fBlarge_read\fP
+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.
+.TP
+\fBdirect_io\fP
+This option disables the use of page cache (file content cache) in the kernel for this filesystem. This has several affects:
+.IP 1.
+Each \fBread\fP(2) or \fBwrite\fP(2) system call will initiate one or more read or write operations, data will not be cached in the kernel.
+.IP 2.
+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).
+.TP
+\fBmax_read=N\fP
+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).
+.TP
+\fBmax_readahead=N\fN
+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)
+.TP
+\fBmax_write=N\fP
+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.
+.TP
+\fBasync_read\fP
+Perform reads asynchronously. This is the default
+.TP
+\fBsync_read\fP
+Perform all reads (even read-ahead) synchronously.
+.TP
+\fBhard_remove\fP
+The default behavior is that if an open file is deleted, the file is renamed to a hidden file (\fB.fuse_hiddenXXX\fP), 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 \fBENOENT\fP): \fBread\fP(2), \fBwrite\fP(2), \fBfsync\fP(2), \fBclose\fP(2), \fBf*xattr\fP(2), \fBftruncate\fP(2), \fBfstat\fP(2), \fBfchmod\fP(2), \fBfchown\fP(2)
+.TP
+\fBdebug\fP
+Turns on debug information printing by the library.
+.TP
+\fBfsname=NAME\fP
+Sets the filesystem source (first field in \fI/etc/mtab\fP). The default is the mount program name.
+.TP
+\fBsubtype=TYPE\fP
+Sets the filesystem type (third field in \fI/etc/mtab\fP). The default is the mount program name. If the kernel suppports it, \fI/etc/mtab\fP and \fI/proc/mounts\fP will show the filesystem type as \fBfuse.TYPE\fP
+
+If the kernel doesn't support subtypes, the source filed will be \fBTYPE#NAME\fP, or if \fBfsname\fP option is not specified, just \fBTYPE\fP.
+.TP
+\fBuse_ino\fP
+Honor the \fIst_ino\fP field in kernel functions \fBgetattr()\fP and \fBfill_dir()\fP. This value is used to fill in the
+\fIst_ino\fP field in the \fBstat\fP(2), \fBlstat\fP(2), \fBfstat\fP(2) functions and the \fId_ino\fP field in the \fBreaddir\fP(2) function. The filesystem does not have to guarantee uniqueness, however some applications rely on this value being unique for the whole filesystem.
+.TP
+\fBreaddir_ino\fP
+If \fBuse_ino\fP option is not given, still try to fill in the \fId_ino\fP field in \fBreaddir\fP(2). 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 \fB-1\fP.  If \fBuse_ino\fP option is given, this option is ignored.
+.TP
+\fBnonempty\fP
+Allows mounts over a non-empty file or directory. By default these  mounts are rejected to prevent accidental covering up of data, which could for example prevent automatic backup.
+.TP
+\fBumask=M\fP
+Override the permission bits in \fIst_mode\fP set by the filesystem. The resulting permission bits are the ones missing from the given umask value.  The value is given in octal representation.
+.TP
+\fBuid=N\fP
+Override the \fIst_uid\fP field set by the filesystem (N is numeric).
+.TP
+\fBgid=N\fP
+Override the \fIst_gid\fP field set by the filesystem (N is numeric).
+.TP
+\fBblkdev\fP
+Mount a filesystem backed by a block device.  This is a privileged option. The device must be specified with the \fBfsname=NAME\fP option.
+.TP
+\fBentry_timeout=T\fP
+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. \fBentry_timeout=2.8\fP)
+.TP
+\fBnegative_timeout=T\fP
+The timeout in seconds for which a negative lookup will be cached. This means, that if file did not exist (lookup retuned \fBENOENT\fP), 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.
+.TP
+\fBattr_timeout=T\fP
+The timeout in seconds for which file/directory attributes are cached.  The default is 1.0 second.
+.TP
+\fBac_attr_timeout=T\fP
+The timeout in seconds for which file attributes are cached for the purpose of checking if \fBauto_cache\fP should flush the file data on  open. The default is the value of \fBattr_timeout\fP
+.TP
+\fBintr\fP
+Allow requests to be interrupted.  Turning on this option may result in unexpected behavior, if the filesystem does not support request interruption.
+.TP
+\fBintr_signal=NUM\fP
+Specify which signal number to send to the filesystem when a request is interrupted.  The default is hardcoded to USR1.
+.TP
+\fBmodules=M1[:M2...]\fP
+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.
+.SH FUSE MODULES (STACKING)
+Modules are filesystem stacking support to high level API. Filesystem modules can be built into libfuse or loaded from shared object
+.SS "iconv"
+Perform file name character set conversion.  Options are:
+.TP
+\fBfrom_code=CHARSET\fP
+Character set to convert from (see \fBiconv -l\fP for a list of possible values). Default is \fBUTF-8\fP.
+.TP
+\fBto_code=CHARSET\fP
+Character set to convert to.  Default is determined by the current locale.
+.SS "subdir"
+Prepend a given directory to each path. Options are:
+.TP
+\fBsubdir=DIR\fP
+Directory to prepend to all paths.  This option is \fImandatory\fP.
+.TP
+\fBrellinks\fP
+Transform absolute symlinks into relative
+.TP
+\fBnorellinks\fP
+Do not transform absolute symlinks into relative.  This is the default.
+.SH SECURITY
+The fusermount program is installed set-user-gid to fuse. This is done to allow users from fuse group 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:
+.IP 1.
+The user can only mount on a mountpoint, for which it has write permission
+.IP 2.
+The mountpoint is not a sticky directory which isn't owned by the user (like \fI/tmp\fP usually is)
+.IP 3.
+No other user (including root) can access the contents of the mounted filesystem.
+.SH NOTE
+FUSE filesystems are unmounted using the \fBfusermount\fP(1) command (\fBfusermount -u mountpoint\fP).
+.SH "AUTHORS"
+.LP
+The main author of FUSE is Miklos Szeredi <mszeredi@inf.bme.hu>.
+.LP
+This man page was written by Bastien Roucaries <roucaries.bastien+debian@gmail.com> for the
+Debian GNU/Linux distribution (but it may be used by others) from README file.

+ * Option description
+ *
+ * This structure describes a single option, and action associated
+ * with it, in case it matches.
+ *
+ * More than one such match may occur, in which case the action for
+ * each match is executed.
+ *
+ * There are three possible actions in case of a match:
+ *
+ * i) An integer (int or unsigned) variable determined by 'offset' is
+ *    set to 'value'
+ *
+ * ii) The processing function is called, with 'value' as the key
+ *
+ * iii) An integer (any) or string (char *) variable determined by
+ *    'offset' is set to the value of an option parameter
+ *
+ * 'offset' should normally be either set to
+ *
+ *  - 'offsetof(struct foo, member)'  actions i) and iii)
+ *
+ *  - -1			      action ii)
+ *
+ * The 'offsetof()' macro is defined in the <stddef.h> header.
+ *
+ * The template determines which options match, and also have an
+ * effect on the action.  Normally the action is either i) or ii), but
+ * if a format is present in the template, then action iii) is
+ * performed.
+ *
+ * The types of templates are:
+ *
+ * 1) "-x", "-foo", "--foo", "--foo-bar", etc.	These match only
+ *   themselves.  Invalid values are "--" and anything beginning
+ *   with "-o"
+ *
+ * 2) "foo", "foo-bar", etc.  These match "-ofoo", "-ofoo-bar" or
+ *    the relevant option in a comma separated option list
+ *
+ * 3) "bar=", "--foo=", etc.  These are variations of 1) and 2)
+ *    which have a parameter
+ *
+ * 4) "bar=%s", "--foo=%lu", etc.  Same matching as above but perform
+ *    action iii).
+ *
+ * 5) "-x ", etc.  Matches either "-xparam" or "-x param" as
+ *    two separate arguments
+ *
+ * 6) "-x %s", etc.  Combination of 4) and 5)
+ *
+ * If the format is "%s", memory is allocated for the string unlike
+ * with scanf().

+# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN)
+# which have later been changed to m4_define as they aren't part of the
+# exported API, or moved to Autoconf or Automake where they belong.
+#
+# The trouble is, aclocal is a bit thick.  It'll see the old AC_DEFUN
+# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
+# using a macro with the same name in our local m4/libtool.m4 it'll
+# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
+# and doesn't know about Autoconf macros at all.)

+# So we provide this file, which has a silly filename so it's always
+# included after everything else.  This provides aclocal with the
+# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
+# because those macros already exist, or will be overwritten later.
+# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6. 
+#
+# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
