+                    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.

+	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:

+	* 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.

+
+	* 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 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>

+
+	* 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

+
+	* 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>
+

+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

+
+	* Add queuing on contention to per-node lock algorithm, to avoid

+
+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

+	uClibc seems to randomly choose between them.
+
+	* Remove erroneous 'fuse_opt_insert_arg@FUSE_2_5' from

+	parent id
+
+2007-05-25  Miklos Szeredi <miklos@szeredi.hu>
+
+	* lib: don't create new thread for each FORGET request.  FORGET

+	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

+	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>

+	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

+
+	* 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
+

+	fuse_setup_common().  Reported by Szakacsits Szabolcs

+2006-10-26  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fix mount.fuse to use /bin/sh instead of /bin/bash, which is not

+
+	* 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>
+

+2006-10-15  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>
+
+	* Fix one more compatibility bug.  Thanks to Ricardo Correia
+
+	* Fix utimens compilation with uClibc.  Patch from Jamie Guinan
+
+2006-09-22  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fixed several compatibility bugs in low level interface.
+	Reported by Ricardo Correia
+
+	* Add workaround for ARM caching bug
+
+2006-09-16  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Rename new utimes() method to more logical utimens()
+
+2006-09-14  Miklos Szeredi <miklos@szeredi.hu>

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

+	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

+2006-03-17  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>
+
+	* lib: optimize buffer reallocation in fill_dir.
+
+2005-10-17  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Released 2.4.1
+
+2005-10-14  Miklos Szeredi <miklos@szeredi.hu>
+
+	* libfuse: add debug for write result (by Shaun Jackman) and
+	warnings for too large read/write result
+
+2005-10-11  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Spelling fixes, thanks to Ioannis Barkas
+
+2005-10-10  Miklos Szeredi <miklos@szeredi.hu>
+

+	patch
+
+2005-10-07  Miklos Szeredi <miklos@szeredi.hu>
+
+	* highlevel-lib: init() and destroy() methods didn't have an
+	initialized fuse_context.  Bug reported by Tim Stoakes
+
+2005-10-04  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Released 2.4.0
+
+2005-10-03  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Add documentation to fuse_lowlevel.h
+
+	* API cleanups:
+
+	* Remove definitions of unused FATTR_CTIME / FUSE_SET_ATTR_CTIME
+
+	* Move fuse_mount() and fuse_unmount() to fuse_common.h
+
+	* Change the return type of fuse_reply_none() from int to void.
+
+2005-09-30  Miklos Szeredi <miklos@szeredi.hu>
+
+	* kernel: NFS exporting leaked dentries.  Bug found and fixed by
+	Akshat Aranya.
+
+2005-09-29  Miklos Szeredi <miklos@szeredi.hu>
+
+	* fusermount: fix error message, when unable to open /dev/fuse.
+	Report by Balázs Pozsár
+
+2005-09-28  Miklos Szeredi <miklos@szeredi.hu>
+
+	* UClibc fixes from Christian Magnusson
+
+2005-09-27  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Added NAME="%k" to util/udev.rules.  Fix by Mattias Wadman.
+
+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

+
+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>

+
+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>

+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>
+

+	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
+
+	* move linux/fuse.h to fuse_kernel.h
+
+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 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)

+	* 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

+	* Make loopback mount of a fuse file work
+
+2004-02-04  Miklos Szeredi <miklos@szeredi.hu>
+

+
+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 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
+
+
+2003-11-04  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fix kernel version detection (again).  Bugreport by Peter Levart

+	* Added function 'fuse_exit()' which can be used to exit the main
+	loop
+
+2002-12-03  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Added _FILE_OFFSET_BITS=64 define to fuse.h.  Note, that this is
+	an incompatible interface change.
+
+2002-10-28  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Portablility fix (bug reported by C. Chris Erway)
+
+2002-10-25  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Use Mark Glines' fd passing method for default operation instead

+
+2002-10-22  Miklos Szeredi <miklos@szeredi.hu>
+
+	* fix "Stale NFS file handle" bug caused by changes in 2.4.19
+
+2002-10-22  Miklos Szeredi <miklos@szeredi.hu>
+
+	* fix incompatiblity with Red Hat kernels, with help from Nathan
+	Thompson-Amato.
+
+2002-04-18  Mark Glines <mark@glines.org>

+      fuse_mount_ioslave(), which does not need to reexec the
+      FUSE program.
+	* added a small helper util needed by fuse_mount_ioslave().
+
+2002-03-16  Mark Glines <mark@glines.org>
+
+	* use struct fuse_statfs everywhere possible to avoid problems
+      with the headerfiles changing struct statfs member sizes
+
+2002-03-01  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Another RPM spec file for RedHat >= 7 by Ian Pilcher
+
+2002-01-14  Miklos Szeredi <miklos@szeredi.hu>
+
+	* RPM support by Achim Settelmeier
+

+
+	* Version 0.95 released
+
+2002-01-09  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Revaidate all path components not just the last, this means a
+	very small performance penalty for being more up-to-date.
+
+2002-01-08  Miklos Szeredi <miklos@szeredi.hu>
+

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

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