update changelog

When the kernel sends a `Create` message the WinFsp-FUSE layer creates
and opens the file (as per Windows semantics). Sometimes an additional
operation needs to be performed after the file has been opened, which
may fail. In this case the just opened file must be released.

In this particular case the WinFsp-FUSE layer used to call `release`
with an uninitialized path. This commit fixes the problem.

This problem was originally reported in cgofuse (billziss-gh/cgofuse#58)

+v1.10B2 (2021.1 Beta2)::
+
+Changes since v1.9:
+
+* [NEW] WinFsp now supports rebranding of the build products. This is primarily useful to commercial licensees. See https://github.com/billziss-gh/winfsp/wiki/WinFsp-Rebranding for more information.
+
+* [NEW] WinFsp-FUSE has a new method for determining file access in the case where the user's primary SID (Windows Security Identifier) and group SID are the same (for example, this can happen when someone uses a Microsoft account as their primary login).
+** Previously when the user SID and group SID were the same WinFsp-FUSE looked at the UNIX permissions for the owner and the UNIX permissions for the group and used the MOST restrictive permissions, which often resulted in inadvertent "access denied" errors. (For example, if the owner permission was `rw-` and the group permission was `---` the result was `---` and therefore access denied).
+** Going forward this behavior will change. The user and group mode permissions will not be considered together even in the case where the user SID and group SID are the same. This will resolve the access denied errors.
+** However to preserve backward compatibility (there might be some file systems that rely on the old behavior) we will do so in stages. For release v1.10 (2021.1) there is a new registry setting under `HKLM\SOFTWARE\WinFsp` (or `HKLM\SOFTWARE\WOW6432Node\WinFsp` on a 64-bit system) called `DistinctPermsForSameOwnerGroup`, which if set to 1 will direct WinFsp-FUSE to use the new behavior. The default value is 0 which directs WinFsp-FUSE to use the old behavior. This default will change in a future release.
+
+* [FIX] File share access when overwriting a file (e.g. when using `TRUNCATE_EXISTING`) is now done in a manner compatible with NTFS (previously there were cases when overwriting a file where behavior diverged from the NTFS one). (See GitHub issue #364.)
+
+* [FIX] Fixed a problem in the file system shutdown protocol which resolves an occasional access violation in the user mode file system process. Previously it was possible for a file system to crash when stopping itself using `FspFileSystemStopDispatcher`; this problem has been rectified. (See GitHub issue #369.)
+
+* [FIX] Fixed a problem in the FUSE layer where in some rare circumstances the `release` operation could be called with an uninitialized `path` argument. (See GitHub issue billziss-gh/cgofuse#58 and commit f51bdef53427d1bba688fb6c768792fdc22ffc7b).
+
+* [FIX] The `winfsp.h` header no longer defines `FILE_FULL_EA_INFORMATION` when compiled under mingw. This is because the mingw tool chain already includes a definition of this type. (GitHub PR #371. Thanks @lemourin.)

+v1.9 (2021)::
+
+Changes since v1.8:
+
+* [NEW] WinFsp now supports file change notifications and cache invalidations. This functionality is offered via the following new API's:
+** Native API: `FspFileSystemNotify`
+** FUSE API: `fuse_notify`
+** .NET API: `FileSystemHost.Notify`
+
+* [NEW] A native file system (notifyfs) and a .NET file system (notifyfs-dotnet) have been added to showcase the new file change notification API.
+
+* [NEW] A new WinFsp-FUSE option `FileSecurity` has been added that allows the complete specification of file security descriptors using SDDL. (See GitHub issue https://github.com/rclone/rclone/issues/4717#issuecomment-767723287.)
+
+* [FIX] The FSD now correctly handles a rare situation where receiving too many CLOSE calls from the OS (e.g. when caching thousands of files) could result in a bogus "insufficient resources" error. (See commit 0af0bfbe7c45e353d693a2a45965d99fa81f2163.)
+
+* [FIX] WinFsp-FUSE correctly maps SID's from trusted domains to POSIX UID's in a multi-domain environment (using the "trustPosixOffset" attribute). Previously WinFsp-FUSE only handled SID's from the primary domain correctly.
+
+* [FIX] WinFsp-FUSE options such as `volname`, `VolumePrefix`, `FileSystemName`, `ExactFileSystemName` are now truncated when too long. (See GitHub issue #311.)
+
+* [FIX] The WinFsp driver is now started in a thread-safe manner if it is not already running. (See GitHub issue billziss-gh/cgofuse#51.)
+
+* [FIX] Credentials entered in the Credentials dialog (when mapping network drives) are no longer saved by default. (See GitHub PR #342. Thanks @gaotxg.)

+DeviceIoControl(Handle, FSP_FSCTL_QUERY_WINFSP, 0, 0, 0, 0, &Bytes, 0)
+----
++
+If the return value is TRUE this is a WinFsp file system.
+
+* [FSD] A fix regarding concurrency of READs on the same file: WinFsp was supposed to allow concurrent READ requests on the same file (e.g. two concurrent overlapped `ReadFile` requests on the same `HANDLE`) to be handled concurrently by the file system; unfortunately due to a problem in recent versions of WinFsp READ requests on the same file were serialized. This problem has now been fixed. See GitHub issue #291 for more details.
+** *NOTE*: It may be that some file system was inadvertently relying on WinFsp's implicit serialization of READs in this case. Please test your file system thoroughly against this version, especially with regard to READ serialization. Related XKCD: https://imgs.xkcd.com/comics/workflow.png

+
+
+v1.5 (2019.3)::
+
+Changes since v1.4:
+
+* [GEN] WinFsp file systems can now be used by WSLinux. File systems must enable this support by setting the `FSP_FSCTL_VOLUME_PARAMS::WslFeatures` bit. Use the command `sudo mount -t drvfs x: /mnt/x` to mount.
+* [GEN] Extended attribute support has been added for all WinFsp API's: native, .NET, FUSE2 and FUSE3.
+* [GEN] Mount Manager support has been added and it works for current and new file systems:
+** If the file system mountpoint is in the syntax `\\.\X:` then the Mount Manager is used.
+** If the file system mountpoint is in the syntax `X:` then `DefineDosDeviceW` is used (i.e. same as today).
+** If the file system mountpoint is in the syntax `X:\DIR` then a reparse point is used and the file system is mounted as a directory (i.e. same as today).
+** Caveats:
+*** It requires Administrator access. This is because opening the `\\.\MountPointManager` device requires Administrator access.
+*** It currently works with drives (`\\.\X:`) but not directories (`\\.\X:\DIR`).
+*** Mount Manager drives created by WinFsp are transient. WinFsp takes various steps to ensure that this is the case.
+*** Mount Manager drives are global and are visible across Terminal Services sessions (they go into the `\GLOBAL??` portion of the NT namespace).
+* [FSD] Support for kernel-mode file systems on top of WinFsp has been added. See `FspFsextProvider`. This is in preparation for WinFuse - FUSE for Windows and WSLinux.
+* [FSD] FastIO support has been added. FastIO operations are enabled on cache-enabled file systems with the notable exception of `FastIoQueryOpen`, which allows opening files in kernel mode; this operation requires the file system to specify the `FSP_FSCTL_VOLUME_PARAMS::AllowOpenInKernelMode` flag.
+* [FSD] Support for `FileFsSectorSizeInformation` and `IOCTL_STORAGE_QUERY_PROPERTY / StorageAccessAlignmentProperty` has been added.
+* [DLL] The `FspFileSystemStartDispatcher` default number of threads (`ThreadCount==0`) has been changed. See commit 3902874ac93fe40685d9761f46a96358ba24f24c for more.
+* [FUSE] FUSE has new `-o UserName=DOMAIN+USERNAME` and `-o GroupName=DOMAIN+GROUPNAME` options. These function like the `-o uid=UID` and `-o gid=GID` options, but accept Windows user and groups names.
+* [FUSE] FUSE has new `-o dothidden` option that is used to add the Windows hidden file attribute to files that start with a dot.
+* [FUSE] FUSE has new `-o create_file_umask=nnn` and `-o create_dir_umask=nnn` options that allow for more control than the `-o create_umask=nnn` option.
+* [FUSE] FUSE has new `--ExactFileSystemName=FSNAME` option that removes the "FUSE-" prefix from the file system name. (Use with caution: see discussion in PR #251.) (Thanks @johntyner.)
+* [.NET] The .NET API now supports asynchronous handling of `Read`, `Write` and `ReadDirectory`. (Thanks @dworkin.)
+* [.NET] The .NET API now supports fine-grained timeouts (`VolumeInfoTimeout`, `DirInfoTimeout`, etc).
+* [.NET] The .NET API has new method `FileSystemHost.MountEx` that adds a `ThreadCount` parameter.
+* [LAUNCH] The Launcher can now rewrite path arguments passed to file systems during launching using "Path Transformation Language". See commit a73f1b95592617ac7484e16c2e642573a4d65644 for more.
+* [MEMFS] A new memfs FUSE3 file system written in C++ has been added. See `tst/memfs-fuse3`.
+* [AIRFS] John Oberschelp has done some fantastic work adding persistence to the airfs file system. (Thanks @JohnOberschelp.)
+* [FIX] Fixes for very large (> 4GiB) files. (Thanks @dworkin.)
+* [FIX] A fix for how FUSE handles the return value from `opendir`. (GitHub issue billziss-gh/sshfs-win#54)
+* [FIX] A fix for an invalid UID to SID mapping on domains with a lot of users. (Thanks @sganis.)
+* [FIX] A fix on the C++ layer. (Thanks @colatkinson.)
+* Other fixes and improvements.

+
+
+v1.5B3 (2019.3 B3)::
+
+Changes since v1.4:
+
+* [GEN] WinFsp file systems can now be used by WSLinux. Use the command `sudo mount -t drvfs x: /mnt/x` to mount.
+* [GEN] Extended attribute support has been added for all WinFsp API's: native, .NET, FUSE2 and FUSE3.
+* [GEN] Mount Manager support has been added and it works for current and new file systems:
+** If the file system mountpoint is in the syntax `\\.\X:` then the Mount Manager is used.
+** If the file system mountpoint is in the syntax `X:` then `DefineDosDeviceW` is used (i.e. same as today).
+** If the file system mountpoint is in the syntax `X:\DIR` then a reparse point is used and the file system is mounted as a directory (i.e. same as today).
+** Caveats:
+*** It requires Administrator access. This is because opening the `\\.\MountPointManager` device requires Administrator access.
+*** It currently works with drives (`\\.\X:`) but not directories (`\\.\X:\DIR`).
+*** Mount Manager drives created by WinFsp are transient. WinFsp takes various steps to ensure that this is the case.
+*** Mount Manager drives are global and are visible across Terminal Services sessions (they go into the `\GLOBAL??` portion of the NT namespace).
+* [FSD] Support for kernel-mode file systems on top of WinFsp has been added. See `FspFsextProvider`. This is in preparation for WinFuse - FUSE for Windows and WSLinux.
+* [FSD] FastIO support has been added. FastIO operations are enabled on cache-enabled file systems with the notable exception of `FastIoQueryOpen`, which allows opening files in kernel mode; this operation requires the file system to specify the `FSP_FSCTL_VOLUME_PARAMS::AllowOpenInKernelMode` flag.
+* [FSD] Support for `FileFsSectorSizeInformation` and `IOCTL_STORAGE_QUERY_PROPERTY / StorageAccessAlignmentProperty` has been added.
+* [DLL] The `FspFileSystemStartDispatcher` default number of threads (`ThreadCount==0`) has been changed. See commit 3902874ac93fe40685d9761f46a96358ba24f24c for more.
+* [FUSE] FUSE has new `-o UserName=DOMAIN+USERNAME` and `-o GroupName=DOMAIN+GROUPNAME` options. These function like the `-o uid=UID` and `-o gid=GID` options, but accept Windows user and groups names.
+* [FUSE] FUSE has new `-o dothidden` option that is used to add the Windows hidden file attribute to files that start with a dot.

+
+* Multiple Launcher changes:
+** New `FspLaunch` API. File systems can be started, stopped, queried and listed using `FspLaunchStart`, `FspLaunchStop`, `FspLaunchGetInfo` and `FspLaunchGetNameList`. The API is available in <winfsp/launch.h>
+** New Launcher registry settings `RunAs` and `WorkDirectory`. `RunAs` allows the laucher to launch a file system process under the service accounts LocalService and NetworkService. `WorkDirectory` can be used to specify the work directory for a newly launched file system process.
+* `FSP_FSCTL_VOLUME_PARAMS::FlushAndPurgeOnCleanup` limits the time that Windows keeps files open after an application has closed them. This purges the cache on the last `CloseHandle`, which is a performance drawback.
+** This is now the default behavior on FUSE. To revert to the previous behavior of keeping files open indefinitely use `-o KeepFileCache`.
+* `FSP_FSCTL_VOLUME_PARAMS` has been extended with fine-grained timeouts: `VolumeInfoTimeout`, `DirInfoTimeout`, `SecurityTimeout`, `StreamInfoTimeout`. Set `FSP_FSCTL_VOLUME_PARAMS::Version == sizeof(FSP_FSCTL_VOLUME_PARAMS)` to access the new fields.
+** New FUSE optons `VolumeInfoTimeout`, `DirInfoTimeout` complement the existing `FileInfoTimeout`.
+* The FSD (File System Driver) and its interaction with the Windows MUP (Multiple UNC Provider) has been changed. In practice this eliminates the delays experienced when right-clicking on a WinFsp-backed network drive in the Windows Explorer. (GitHub issue #87.)
+* The WinFsp network provider is now added first in the provider order list. Previously it was added last. (GitHub PR #131; thanks @felfert.)
+* The WinFsp installer now uses the Wix `Provides` dependency extension to provide a `WinFsp` dependency key. (GitHub PR #129; thanks @felfert.)

+
+Changes since v1.1:
+
+- WinFsp-FUSE now supports BSD flags (Windows file attributes) during `getattr` and `fgetattr`. It also adds the `chflags` operation. BSD flags support requires use of the `FSP_FUSE_CAP_STAT_EX` capability and the new `struct fuse_stat_ex` which includes an `st_flags` field. If the preprocessor macro `FSP_FUSE_USE_STAT_EX` is defined before inclusion of `<fuse.h>` then `struct fuse_stat` will also be defined to include the `st_flags` field.
+- WinFsp-FUSE also adds the following OSXFUSE operations: `setcrtime`, `setchgtime`. These can be used to set the creation (birth) time and change (ctime) time of a file.
+- New `GetDirInfoByName` file system operation adds fast queries of directory info by file name rather than pattern [e.g. `FindFirstFileW(L"foobar", FindData)`]. Tests with fsbench showed that such queries are sped up by an order of magnitude when using `GetDirInfoByName` in MEMFS. Case-sensitive FUSE file systems get this optimization for free. The .NET layer also adds `GetDirInfoByName`.
+- New `FspFileSystemOperationProcessId` API adds support for getting the originating process ID (PID) during `Create`, `Open` and `Rename` calls. FUSE file systems can now access `fuse_context::pid`. The .NET layer also adds `GetOperationProcessId`.
+- New command line tool `fsptool` allows command line access to some WinFsp features.
+- The WinFsp launcher now passes the name of the user who launched the file system as a special parameter %U. This is useful to file systems that use the launcher infrastructure, such as SSHFS-Win. [Please note that in earlier betas the user name was passed as parameter %3; the previous method was insecure and is no longer supported.]

+- New command line tool `fsptool` allows command line access to some WinFsp features.
+- The WinFsp launcher now passes the username of the user who launched the file system as parameter %3. This is useful to file systems that use the launcher infrastructure, such as SSHFS-Win.
+- Important GitHub issues fixed: #96, #97, #103, #107
+
+
+v1.2B2 (2017.2 B2)::
+
+Changes since v1.1:
+
+- New command line tool `fsptool` allows command line access to some WinFsp features.
+- New `GetDirInfoByName` file system operation adds fast queries of directory info by file name rather than pattern [e.g. `FindFirstFileW(L"foobar", FindData)`]. Tests with fsbench showed that such queries are sped up by an order of magnitude when using `GetDirInfoByName` in MEMFS. Case-sensitive FUSE file systems get this optimization for free.

+- New `GetDirInfoByName` file system operation adds fast queries of directory info by file name rather than pattern [e.g. `FindFirstFileW("foobar", FindData)`]. Tests with fsbench showed that such queries are sped up by an order of magnitude when using `GetDirInfoByName` in MEMFS.
+- New `FspFileSystemOperationProcessId` API adds support for getting the originating process ID (PID) during `Create`, `Open` and `Rename` calls.
+
+
+v1.1 (2017.1)::
+
+This release brings some major new components and improvements.
+
+- A .NET layer that allows the creation of file systems in managed mode. This is contained in the new `winfsp-msil.dll`. The new .NET layer is being tested with the WinFsp test suites and Microsoft's ifstest.
+- FUSE for Cygwin is now included with the installer.
+- FUSE now has a `-ovolname=VOLNAME` parameter that allows setting the volume label. Thanks @samkelly.
+- A number of other FUSE improvements have been made (see issue #85).
+
+NOTE: The C++ layer included in the v1.1 beta releases is not part of this release as it is still work in progress. It can be found in `inc/winfsp/winfsp.hpp` in the WinFsp source repository.
+
+
+v1.1B3 (2017.1 B3)::
+
+v1.1B2 (2017.1 B2)::
+
+v1.1B1 (2017.1 BETA)::
+
+This release brings some major new components and improvements.
+
+- A .NET layer that allows the creation of file systems in managed mode. This is contained in the new `winfsp-msil.dll`. The new .NET layer is being tested with the WinFsp test suites and Microsoft's ifstest.
+- A simple C++ layer can be found in `inc/winfsp/winfsp.hpp`.
+- FUSE for Cygwin is now included with the installer.
+- FUSE now has a `-ovolname=VOLNAME` parameter that allows setting the volume label. Thanks @samkelly.
+
+
+v1.0::
+
+This is the WinFsp 2017 release! :tada:
+
+- The API is now *FROZEN*. Breaking API changes will receive a major version update (`2.0`). Incremental API changes will receive a minor version update (`1.x`).
+- Adds chocolatey package. Try `choco install winfsp` (note: pending approval from chocolatey.org).
+- FUSE `-d` output now always goes to stderr. There is also a new `-oDebugLog=FILE` switch to specify a debug output file.
+- FUSE now provides a default `statfs` implementation if a file system does not provide one.
+- The WinFsp DLL now exports `fuse_*` symbols in addition to the `fsp_fuse_*` symbols. These symbols are for use with programs that use FFI technology such as jnr-fuse and fusepy *ONLY*. They are not supposed to be used by native C/C++ programs. Such programs are supposed to include the `<fuse.h>` headers.
+
+
+v1.0RC3::
+
+This is the WinFsp 2017 Release Candidate 3, which should be the last Release Candidate according to the current plan. This release fixes a major issue with some file systems and includes a few smaller changes:
+
+- Fixes GitHub issue #55. Prior to this fix it was possible for a rogue process (or faulty file system) to crash Windows using WinFsp. For full details read http://www.osronline.com/showthread.cfm?link=282037[this thread].
+- Introduces the `FspFileSystemSetMountPointEx` API, which allows the specification of a security descriptor when mounting over a directory.
+- Introduces the `FspVersion` API, which allows the retrieval of the WinFsp DLL version. Currently this reports `0x00010000` (version `1.0`).
+- Introduces the `FSP_FUSE_CAP_CASE_INSENSITIVE` and `FSP_FUSE_CAP_READDIR_PLUS` WinFsp-FUSE flags. The `FSP_FUSE_CAP_CASE_INSENSITIVE` flag allows a file system to mark itself as case-insensitive. The `FSP_FUSE_CAP_READDIR_PLUS` flag allows a file system to include full `stat` details when responding to the `readdir` operation (thus avoiding extraneous `getattr` calls).
+- When using WinFsp-FUSE over Cygwin, POSIX paths can be used as mountpoints.
+- Fixes GitHub issue #45. Prior to this fix, file systems that do not properly implement `Cleanup` (including FUSE file systems) would at times disallow renaming of directories.
+
+
+v1.0RC2::
+
+This is the WinFsp 2017 Release Candidate 2. Some important changes included below:
+
+- WinFsp is now available under the GPLv3 with a special exception for Free/Libre and Open Source Software.
+- The location of the WinFsp launcher registry entries is now `HKEY_LOCAL_MACHINE\Software\WinFsp\Services`. [On Win64 the actual location is `HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\WinFsp\Services`.] This change was necessary to avoid loss of third party file system registry entries during WinFsp uninstallation. [See GitHub issue #31.]
+- Despite stating in the previous release that the API has been finalized the `ReadDirectory` `FSP_FILE_SYSTEM_INTERFACE` operation has been changed. Extensive testing with multiple file systems has shown that `ReadDirectory` was hard to implement correctly. The new definition should make implementation easier for most file systems. [See GitHub issue #34.]
+- Some API's to facilitate `ReadDirectory` implementation have been added. Look for `FspFileSystem*DirectoryBuffer` symbols.
+- The installer now (optionally) installs a sample file system called "passthrough". This is a simple file system that passes all operations to an underlying file system. There is also a tutorial for this file system (in the doc directory).
+- The installer now (optionally) installs a sample file system called "passthrough-fuse". This file system performs the same function as the "passthrough" file system, but uses the FUSE compatibility layer. It builds and runs on both Windows and Cygwin.
+
+
 v1.0RC1::
 
 This is the WinFsp 2017 Release Candidate 1. It has been tested extensively in a variety of scenarios for stability and correct file system semantics. Some of the more important changes:

-WinFsp is a set of software components for Windows computers that allows the creation of user mode file systems. In this sense it is similar to FUSE (Filesystem in Userspace), which provides the same functionality on UNIX-like computers.
+## Benefits
 
-Some of the benefits of using WinFsp are listed below:
+### Stability
+
+WinFsp is very stable. There are no known kernel mode crashes and it does not suffer from resource leaks or similar problems. WinFsp owes this stability to its [Design](doc/WinFsp-Design.asciidoc) and its rigorous [Testing Regime](doc/WinFsp-Testing.asciidoc).
+
+### Performance
+
+WinFsp outperforms its competition and in many scenarios performs as well as NTFS. Read more about its [Performance](doc/WinFsp-Performance-Testing.asciidoc).
+
+<p align="center">
+    <img src="doc/WinFsp-Performance-Testing/file_tests.png" height="300"/>
+    <img src="doc/WinFsp-Performance-Testing/rdwr_tests.png" height="300"/>
+</p>
+
+### Compatibility
+
+WinFsp strives for compatibility with NTFS and file system correctness. For the full details see the [Compatibility](doc/NTFS-Compatibility.asciidoc) document.
+
+### Easy to Use
+
+WinFsp has an easy to use but comprehensive API.
+
+* This simple [Tutorial](doc/WinFsp-Tutorial.asciidoc) explains how to build a file system.
+* Consult the [API Reference](http://www.secfs.net/winfsp/apiref/) for native development.
+* Includes .NET layer for managed development. See [src/dotnet](src/dotnet).
+* Includes FUSE 2.8 compatibility layer: [fuse/fuse.h](inc/fuse/fuse.h)
+* Includes FUSE 3.2 compatibility layer: [fuse3/fuse.h](inc/fuse3/fuse.h)
+
+### Other Benefits
 
-* Very well-tested and stable. Read about its [Testing Strategy](doc/WinFsp-Testing.asciidoc).
-* Very fast. Read about its [Performance](doc/WinFsp-Performance-Testing.asciidoc).
-* Strives for compatibility with NTFS. Read about its [Compatibility](doc/NTFS-Compatibility.asciidoc ).
-* Easy to understand but comprehensive API. Consult the [API Reference](http://www.secfs.net/winfsp/apiref/).
-* FUSE compatibility layer for native Windows and Cygwin. See [fuse.h](inc/fuse/fuse.h).
 * Signed drivers provided on every release.
-* Available under the GPLv3.
+* Available under the [GPLv3](License.txt) license with a special exception for Free/Libre and Open Source Software.

 ## Project Organization
 
-WinFsp consists of a kernel mode FSD (File System Driver) and a user mode DLL (Dynamic Link Library). The FSD interfaces with NTOS (the Windows kernel) and handles all interactions necessary to present itself as a file system driver to NTOS. The DLL interfaces with the FSD and presents an easy to use API for creating user mode file systems.

 The project source code is organized as follows:
 
-* build/VStudio: WinFsp solution and project files.
-* doc: The WinFsp design documents and additional documentation can be found here.
-* ext/tlib: A small test library originally from the secfs (Secure Cloud File System) project.
-* ext/test: Submodule pointing to the secfs.test project, which contains a number of tools for testing Windows and POSIX file systems.
-* inc/winfsp: Public headers for the WinFsp API.
-* inc/fuse: Public headers for the FUSE compatibility layer.
-* src/dll: Source code to the WinFsp DLL.
-* src/dll/fuse: Source code to the FUSE compatibility layer.
-* src/launcher: Source code to the launcher service and the launchctl utility.
-* src/sys: Source code to the WinFsp FSD.
-* opt/cygfuse: Source code for the Cygwin FUSE package.
-* tst/memfs: Source code to an example file system written in C++ (memfs).

 ## Building and Running
 
 In order to build WinFsp you will need the following:
 
-* Windows 10
-* Visual Studio 2015
+* Visual Studio 2015 - 2019
 * Windows Driver Kit (WDK) 10
+    - **NOTE**: When using the latest WDK (Windows 10.0.18362.1) with Visual Studio 2015 you may get an error about a missing task `ValidateNTTargetVersion`. The fix is to edit the file `\Program Files (x86)\Windows Kits\10\build\WindowsDriver.Common.targets` and modify the `UsingTask` line for `ValidateNTTargetVersion` as follows:
+        ```
+        <UsingTask TaskName="ValidateNTTargetVersion" AssemblyFile="$(WDKContentRoot)build\bin\Microsoft.DriverKit.Build.Tasks.16.0.dll"/>
+        ```
 * [Wix toolset](http://wixtoolset.org)
 
-If you build the driver yourself it will not be signed and Windows will refuse to load it unless you enable "testsigning". You can enable "testsigning" using the command `bcdedit.exe -set testsigning`. For more information see this [document](http://www.secfs.net/winfsp/develop/debug/).
+To fully build WinFsp (including the installer) you must use `tools\build.bat`. By default it builds a Release build, but you can choose either the Debug or Release configuration by using the syntax:

+        <description>
+WinFsp is a set of software components for Windows computers that allows the creation of user mode file systems. In this sense it is similar to FUSE (Filesystem in Userspace), which provides the same functionality on UNIX-like computers.
+
+Some of the benefits of using WinFsp are listed below:
+
+* Very well-tested and stable.
+* Very fast.
+* Strives for compatibility with NTFS.
+* Easy to understand but comprehensive API.
+* FUSE compatibility layer for native Windows and Cygwin.
+* Signed drivers provided on every release.
+* Available under the GPLv3 license with a special exception for Free/Libre and Open Source Software.
+
+To verify installation:
+
+* For 64-bit Windows: `net use m: \\memfs64\share` from the command prompt.
+* For 32-bit Windows: `net use m: \\memfs32\share`
+* For Cygwin: `net use m: '\\memfs64\share'`
+* To delete the drive: `net use m: /delete`

+= Frequently Asked Questions
+
+== General
+
+[qanda]
+
+I am running Windows 7 and I am finding that the installed driver is not signed.::
+
+    Your Windows 7 OS is missing SHA-2 Code Signing Support. You need to install the following security advisory that will rectify the problem:
+    https://technet.microsoft.com/en-us/library/security/3033929.aspx
+
+
+Disconnecting (unmapping) a network drive does not work.::
+
+    You may have Dokany installed. Dokany installs its own Network Provider DLL that unfortunately interferes with the WinFsp handling of network drives. The solution is to change your system's Network Provider order and ensure that the WinFsp Network Provider runs before the Dokany one. Instructions on how to change the Network Provider order can be found in this http://blogs.interfacett.com/changing-the-network-provider-order-in-windows-10[article].
+
+
+Case-sensitive file systems do not work properly when mounted as a directory.::
+
+    This is fixed as of WinFsp 2018.2 B3.
+
+
+Why is the DLL not installed in the Windows system directories?::
+
+    It is true that this would make it convenient to load the DLL, because the Windows loader looks into the Windows system directories when it loads DLL's. However, in the opinion of the WinFsp author, software that does not ship with the OS should not be installing components in the system directories.
++
+There are a few alternative methods to overcome this problem. WinFsp recommends marking the WinFsp DLL as "delay load" and then using `FspLoad` to dynamically load the DLL during process initialization. For more information see the WinFsp Tutorial.
+
+
+Does WinFsp provide debugging symbols?::
+
+    Public debugging symbols are already included in the installer. You need to install the "Developer" feature; the symbols can be found in the `sym` directory under the WinFsp installation directory.
+
+
+Is there a maximum number of concurrent file systems?::
+
+    WinFsp does not have a hard limit of how many file systems can be created or how many processes can create file systems.
++
+As of the commits required to fix issue #55, there is however a hash table inside the FSD that uses PID's (Process ID's) as keys. This hash table currently expects that in general there will not be more than 50 processes creating file systems. However this is not a hard limit.
+
+
+== FUSE
+
+[qanda]
+
+Which version of FUSE does WinFsp-FUSE support?::
+
+    It supports both the FUSE 2.8 and FUSE 3.2 API's. For the FUSE 2.8 API include `<fuse/fuse.h>`. For the FUSE 3.2 API include `<fuse3/fuse.h>`.
+
+
+FUSE on UNIX systems mounts file systems over an existing directory. When mounting a WinFsp-FUSE file system on a directory, the directory is created and later deleted when the file system goes away. What is the reason for this incompatibility?::
+
+    It would be preferrable if WinFsp-FUSE behaved like FUSE on UNIX in this instance. However there are a number of reasons that this is not the case.
++
+When mounting over directories in Windows, WinFsp-FUSE uses a special construct called a reparse point. Reparse points are a general mechanism for adding special behavior to files and directories. One of the possible reparse points is the "mountpoint" reparse point (often called "junction"), which converts a directory into a mount point.
++
+With this in mind here are the reasons for the current WinFsp-FUSE behavior:
++
+- Symmetry with mounting on a drive. On Windows drives are created when the file system comes into existence and deleted when it is gone.
+- Inability to mount over a non-empty directory on Windows. On FUSE/UNIX this is possible, but not on Windows because NTFS disallows the creation of (mountpoint) reparse points on non-empty directories.
+- Most importantly: inability to guarantee that the mount point will cease to exist if the file system crashes. WinFsp attempts to guarantee that all resources used by a file system will get cleaned up. This is certainly true for the kernel-mode FSD, but an attempt is made to do so also in user mode. For this reason, drive symbolic links are marked as temporary and (importantly for our discussion) mount directories are opened with `FILE_FLAG_DELETE_ON_CLOSE`. There is no way to guarantee the removal of a reparse point in the same way.
+
+
+WinFsp-FUSE does not have the ability to support multiple file systems from within the same process. Why?::
+
+    This is supported as of WinFsp 2018.2 B2.
+
+
+I have problems getting permissions to work properly in a WinFsp-FUSE file system. Can you help?::
+
+    The WinFsp-FUSE layer includes a built-in command line option that can help: `-o uid=-1`. This instructs the WinFsp-FUSE layer to present all file system files as if they are owned by the user that launched the file system.
++
+Alternatives include `-o uid=-1,gid=-1`, which presents files as owned by the user *and* group that launched the file system and `-o uid=-1,gid=11`, which presents files as owned by the user that launched the file system and the group "Authenticated Users". (The `fsptool` utility in the `bin` subdirectory of the WinFsp installation directory can be used to convert Windows accounts/SID's to UID's and vice versa.)

+# WinFsp - Windows File System Proxy
+
+[[WinFsp-Icon.png]]
+
+Developing file systems is a challenging proposition. Developing file systems for Windows is an order of magnitude more difficult. WinFsp eases the task of writing a new file system for Windows. WinFsp file systems are user mode programs and they can be written in a variety of languages and frameworks.
+
+The documentation available here discusses various aspects of WinFsp.
+
+## Programming
+
+- The [[Tutorial|WinFsp-Tutorial]] describes how to create a simple, but complete file system in C/C++.
+- The [[API Reference|WinFsp-API-winfsp.h]] describes the native WinFsp API.
+- There is also a FUSE compatibility layer for native Windows and Cygwin. See fuse.h in the source repository.
+- This [[document|Native-API-vs-FUSE]] discusses the need for both a native API and FUSE and gives some pointers on which one to choose.
+- Since release 2019.3 WinFsp supports development of file systems in kernel mode. This [[document|WinFsp-Kernel-Mode-File-Systems]] discusses how to write such file systems.
+
+## Design
+
+- The [[Design|WinFsp-Design]] document describes the high-level design of WinFsp.
+- The [[IPC|WinFsp-as-an-IPC-Mechanism]] document offers insights into the WinFsp Inter-Process Communication mechanism.
+- The [[Queued Events|Queued-Events]] document discusses a low-level synchronization primitive that is largely responsible for the excellent performance of the WinFsp IPC mechanism.
+- The [[Service Architecture|WinFsp-Service-Architecture]] document discusses how to intergrate a file system into Windows as a service and the reasons to do so.
+- The [[SSHFS Port Case Study|SSHFS-Port-Case-Study]] document chronicles the creation of the WinFsp-FUSE compatibility layer and the decisions that led to its design.
+
+## Testing
+
+- The [[Testing|WinFsp-Testing]] document discusses the WinFsp testing strategy and how WinFsp achieves correctness and stability.
+- The [[Performance|WinFsp-Performance-Testing]] document compares WinFsp performance against other file systems.
+
+## Compatibility
+
+- The [[Compatibility|NTFS-Compatibility]] document discusses current WinFsp compatibility with NTFS.

+= Queued Events - Windows kernel events with IOCP scheduling characteristics
+
+In this article I am discussing _Queued Events_. _Queued Events_ are a Windows kernel synchronization mechanism that I invented for https://github.com/billziss-gh/winfsp[WinFsp - FUSE for Windows]. _Queued Events_ behave like kernel Synchronization Events (i.e. Win32 auto-reset events), but provide scheduling characteristics similar to those of I/O Completion Ports.
+
+== The Problem
+
+During the later stages of WinFsp development I decided to do some performance testing to understand its behavior and find opportunities for optimization. I found out that WinFsp performed very well in most tested scenarios, but there was one test that seemed to have bad performance for no particular reason.
+
+I ended up profiling this issue using xperf (included in the https://docs.microsoft.com/en-us/windows-hardware/test/wpt/[Windows Performance Toolkit]), which allows for kernel-level profiling. I spent considerable time looking at the profiling results, but could identify no obvious issue with my code.
+
+After a day or two of doing this and being stumped I finally had a lightbulb moment: what if the issue is not with my code, but with how the OS schedules threads? Sure enough I had xperf trace context switches and found that on good runs the OS would context switch my file system threads relatively rarely; on bad runs the OS would context switch my threads excessively.
+
+After contemplating this issue I realized that this was happening because the OS was trying to schedule my threads in a "fair" manner. Windows in general tries to give every thread a chance to run. This can be counter-productive in server-like programs (such as file systems), where all server threads are equivalent and it is actually better to reuse the same thread (if possible) to avoid context switching and other negative effects.
+
+== The Solution
+
+One way of looking at WinFsp is as an IPC (Inter-Process Communication) mechanism. The Windows kernel packages file system operations (open, close, read, write) as IRP's (I/O Request Packets) which it sends to WinFsp. WinFsp places them in an _I/O Queue_; at a later time the threads in a user mode file system retrieve the IRP's from the _I/O Queue_ and service them.
+
+The _I/O Queue_ had gone through multiple iterations, but at the time I was looking at this issue it was using Windows kernel Synchronization Event's (Win32 auto-reset events) for managing threads. The problem was that a wait on a Synchronization Event would be satisfied in a "fair" manner, thus resulting to excessive context switching and bad performance in some circumstances. I needed to find a way to convince Windows to schedule my threads in an "unfair" manner, giving preference to the same thread as much as possible.
+
+I started considering different schemes where I would associate a different event per thread thus being able to wake up the "correct" thread myself and effectively writing my own mini-scheduler. Luckily I had another lightbulb moment: I/O completion ports already do this better than I would ever be able to!
+
+The kernel portion of an I/O Completion Port is called a https://msdn.microsoft.com/en-us/library/windows/hardware/ff549547(v=vs.85).aspx[KQUEUE]. KQUEUE's are (unfortunately) not directly exposed to user mode, however they are at the core of the user mode I/O Completion Ports. KQUEUE's are the main reason I/O Completion Ports are so fast as they provide the following scheduling characteristics:
+
+- They have a Last-In First-Out (LIFO) wait discipline.
+- They limit the number of threads that can be satisfied concurrently.
+
+I briefly considered the idea of building _I/O Queues_ directly on top of KQUEUE's, but soon dismissed this idea because _I/O Queues_ are not simple queues but provide additional services, such as IRP cancelation, IRP expiration, etc.
+
+== Queued Events
+
+In an ideal scenario I wanted to continue using my implementation of _I/O Queues_ which had undergone considerable testing and I knew it worked. But somehow I had to convince the Windows kernel to change the scheduling characteristics of Synchronization Events to mirror those of a KQUEUE.
+
+Then I had lightbulb no 3: _Queued Events_ or how to make a queue behave like a Synchronization Event.
+
+Here is how _Queued Events_ work. A _Queued Event_ consists of a KQUEUE and a spin lock. There is also a single dummy item that can be placed in the KQUEUE.
+
+The KQUEUE is guaranteed to contain either 0 or 1 items. When the KQUEUE contains 0 items the _Queued Event_ is considered non-signaled. When the KQUEUE contains 1 items the _Queued Event_ is considered signaled.
+

+endif::env-browser[]
+ifndef::env-browser[image::Queued-Events/states.png[]]
+
+To transition from the non-signaled to the signaled state, we acquire the spin lock and then insert the dummy item in the KQUEUE using https://msdn.microsoft.com/en-us/library/windows/hardware/ff549570(v=vs.85).aspx[KeInsertQueue]. To transition from the signaled to the non-signaled state, we simply (wait and) remove the dummy item from the KQUEUE using https://msdn.microsoft.com/en-us/library/windows/hardware/ff549605(v=vs.85).aspx[KeRemoveQueue] (without the use of the spin lock).
+
+----
+EventSet:
+    AcquireSpinLock
+    if (0 == KeReadState())          // if KQUEUE is empty
+        KeInsertQueue(DUMMY);
+    ReleaseSpinLock
+
+EventWait:
+    KeRemoveQueue();                 // (wait and) remove item
+----
+
+First notice that EventSet is serialized by the use of the spin lock. This guarantees that the dummy item can be only inserted ONCE in the KQUEUE and that the only possible signaled state transitions for EventSet are 0->1 and 1->1. This is how https://msdn.microsoft.com/en-us/library/windows/hardware/ff553253(v=vs.85).aspx[KeSetEvent] works for a Synchronization Event.
+
+Second notice that EventWait is not protected by the spin lock, which means that it can happen at any time including concurrently with EventSet or another EventWait. Notice also that for EventWait the only possible transitions are 1->0 or 0->0 (0->block->0). This is how https://msdn.microsoft.com/en-us/library/windows/hardware/ff553350(v=vs.85).aspx[KeWaitForSingleObject] works for a Synchronization Event.

+endif::env-browser[]
+ifndef::env-browser[image::Queued-Events/transitions.png[]]
+
+We now have to consider what happens when we have one EventSet concurrently with one or more EventWait's:
+
+1. The EventWait(s) happen before https://msdn.microsoft.com/en-us/library/windows/hardware/ff549591(v=vs.85).aspx[KeReadState]. If the KQUEUE has an item one EventWait gets satisfied, otherwise it blocks. In this case KeReadState will read the KQUEUE's state as 0 and KeInsertQueue will insert the dummy item, which will unblock the EventWait.
+2. The EventWait(s) happen after KeReadState, but before KeInsertQueue. If the dummy item was already in the KQUEUE the KeReadState test will fail and KeInsertQueue will not be executed, but EventWait will be satisfied immediately. If the dummy item was not in the KQUEUE the KeReadState will succeed and EventWait will momentarily block until KeInsertQueue releases it.
+3. The EventWait(s) happen after KeInsertQueue. In this case the dummy item in is the KQUEUE already and one EventWait will be satisfied immediately.
+
+NOTE: _Queued Events_ cannot cleanly support an EventClear operation. The obvious choice of using KeRemoveQueue with a 0 timeout is insufficient because it would associate the current thread with the KQUEUE and that is not desirable. KeRundownQueue cannot be used either because it disassociates all threads from the KQUEUE.
+
+The complete implementation of _Queued Events_ within WinFsp can be found here: https://github.com/billziss-gh/winfsp/blob/v1.1/src/sys/driver.h#L655-L795
+
+== Queued Events Scheduling Characteristics
+
+Queued Events encapsulate KQUEUE's and therefore inherit their scheduling characteristics:
+
+- They have a Last-In First-Out (LIFO) wait discipline.
+- They limit the number of threads that can be satisfied concurrently.
+
+These characteristics are desirable because they reduce the number of context switches thus speeding up the WinFsp IPC implementation. Performance testing immediately after the incorporation of _Queued Events_ into WinFsp showed significant performance improvements; profiling with xperf showed that context switches among file system threads were now a relatively rare event!

+= WinFsp Container Support
+
+WinFsp gained support for Windows Containers in release 2020.2 B1. This document discusses this new functionality and explains how user mode file systems can take advantage of it.
+
+NOTE: WinFsp support for Windows Containers is at this time highly experimental. It may change substantially in the future or eliminated altogether.
+
+== Windows Containers
+
+Containers are a technology for deployment and execution of applications in an isolated environment. Applications deployed inside a container cannot be affected by or affect applications in other containers or in the host operating system.
+
+Containers on Windows provide isolation via one of two modes:
+
+- The _Hyper-V_ isolation mode where a container runs in its own virtual machine and has its own kernel.
+
+- The _process_ isolation mode where a container runs in a "silo" inside the host operating system's kernel. This is the same model used in containers for Linux.
+
+WinFsp supports containers that use the process isolation mode in versions of Windows 10 1809 and later.
+
+=== Server Silos
+
+Containers using the process isolation mode are called _server silos_. Server silos are built on top of kernel job objects that have been extended with additional capabities useful for containers. Most importantly each server silo has its own object namespace root directory that is distinct from the host's object namespace root directory. This allows for all named kernel objects inside a server silo to be isolated from named objects in other server silos or the host.
+
+The Windows kernel provides a number of DDI's (Device Driver Interfaces) to enable kernel drivers to work with server silos. The WinFsp FSD uses these DDI's to monitor silo creation and termination and manage its own devices within the silo's object namespace.
+
+=== Docker
+
+In order to manage containers on Windows a version of Docker for Windows is needed. In order to use server silos and process isolation with Docker the switch `--isolation=process` must be used when creating a container:
+
+----
+docker run --isolation=process ...
+----
+
+== Containerized User Mode File Systems
+
+The WinFsp 2020.2 B1 release gained the ability for user mode file systems to run inside a server silo container and expose a file system either within the container or to the host operating system. This allows for user mode file systems to be containerized.
+
+There are a few considerations that must be taken into account when deploying a user mode file system in a container:
+
+* When using WinFsp with containers the process isolation mode must be used.
+
+* WinFsp currently supports the Windows Server Core and Windows base images. Work is underway for Nano Server compatibility.
+
+* User mode file systems that run in a container cannot start the FSD, because containers disallow driver loading. (Usually the WinFsp DLL automatically starts the WinFsp FSD when it is not already running, but this is not possible within a container.)
++
+To work around this problem start the FSD outside the container. For example, the FSD can be started in the host using the `sc.exe` utility.
++
+----
+sc.exe start winfsp
+----
++
+Once the FSD has been started it will monitor server silo creation and termination and will set things up so that containerized user mode file systems will be able to interface with it.
+
+* WinFsp file systems typically use the registry to locate and load the WinFsp DLL (see `FspLoad` in `winfsp/winfsp.h`). However the registry inside a container does not contain any WinFsp entries. The easiest workaround is to hardcode the location of the WinFsp installation within the container, which will also hardcode the location of the WinFsp DLL.
+
+* During development it is sometimes useful to bind mount the WinFsp installation directory into the container. For example:
++
+----
+docker run -it --rm --isolation=process "-vC:\Program Files (x86)\WinFsp:C:\Program Files (x86)\WinFsp:RO" mcr.microsoft.com/windows/servercore:2004 cmd.exe
+----
+
+* When a WinFsp based file system is mounted as a disk file system within a container, it is only visible within that container. For example, the drive `Z:` below and associated file system volume will be accessible only within the container:
++
+----
+memfs-x64 -i -F NTFS -m Z:
+----
+
+* When a WinFsp based file system is mounted as a network file system within a container, the file system becomes accessible **outside** the container via its UNC prefix. For example, while the drive `Y:` below will be accessible only within the container, the file system volume will be accessible from both the container and the host via the UNC prefix `\\memfs\share`.
++
+----
+memfs-x64 -i -F NTFS -m Y: -u \memfs\share
+----
++
+The reason that this happens is that server silo containers share the same MUP device object with the host. The MUP (Multiple UNC Provider) is the Windows kernel component responsible for resolving UNC prefixes. It is unclear at this time whether this "leak" from the container to the host via the shared MUP is intentional or whether it is an unintended consequence. I note that the server silo MUP entry in the object namespace is a symbolic link, which suggests that the shared MUP device object was a conscious decision by Microsoft.

+= WinFsp Debugging Setup
+
+In this article I will describe the debugging setup used for WinFsp. Note that my debugging setup is somewhat peculiar, because all development and debugging is done on a Mac computer using two Windows virtual machines: one for development and one for debugging! However my description below should work for a one or two virtual machine setup.
+
+WinFsp is being developed on Windows 10 and debugged and tested on Windows 8 (although it should run correctly on Windows Vista and higher). You will need some virtualization software (I use VirtualBox 5), you will also need a fresh installation of Windows and to configure it properly for kernel debugging and running test signed drivers:
+
+* Create a Windows VM with a descriptive name (e.g. Win8DBG). Mine has a single CPU and just 2GB of memory.
+* Configure your VM for Host Only Networking. This will be used for WinDbg debugging and for deploying WinFsp.
+* Install Windows 8 on Win8DBG. Windows 8 is the minimum version of Windows that supports kernel network debugging.
+* I would recommend not to install your virtualization software guest additions to minimize issues with your debugging VM.
+* Configure Win8DBG for running test signed drivers:
++
+----
+bcdedit.exe -set testsigning on
+----
+* Configure Win8DBG for debugging over the network:
++
+----
+bcdedit /debug on
+bcdedit /dbgsettings net hostip:W.X.Y.Z port:NNNN key:KKKK
+----
+** Note that if you configure your VM with multiple network adapters you must also specify the correct `busparams` argument. You can find the correct `busparams` from the Windows Device Manager. For example, here are the settings on one of my VM's:
++
+----
+>bcdedit /dbgsettings
+busparams               0.8.0
+key                     1.1.1.1
+debugtype               NET
+hostip                  192.168.56.11
+port                    50000
+dhcp                    Yes
+The operation completed successfully.
+----
+* Enable DbgPrint on Win8DBG. Create the following key/value in the registry:
++
+----
+Windows Registry Editor Version 5.00
+
+[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Debug Print Filter]
+"DEFAULT"=dword:0000000f
+----
+* Create a directory on Win8DBG where you will be deploying WinFsp. I use a subdirectory of the Downloads directory:
++
+----
+C:\Users\USERNAME\Downloads\winfsp
+----
+* Make the directory available outside the VM using Windows networking. You can use this new Windows share as an easy means to deploy WinFsp.
++
+----
+copy build\VStudio\build\Debug\winfsp-x64.sys \\Win8DBG\Users\USERNAME\Downloads\winfsp
+----
+* Enable Driver Verifier for WinFsp on Win8DBG. The easiest way to do so is to run `verifier` from the command line.
+* For faster edit-compile-test cycles I strongly recommend to use your virtualization software snapshot feature. For example, in my Win8DBG VM after I set it up exactly how I wanted it, I took a snapshot while the VM was running. Now whenever I want to test WinFsp, I restart that same snapshot and within 3-4 seconds I have a new VM ready for use. Even more importantly whenever there is a hard crash on the VM (happens a lot when developing Windows drivers) I can simply close the crashed VM and restart a new one.
+* On your development machine configure WinDbg to use the Microsoft public symbol servers. From the main menu select File > Symbol File Path and enter:
++
+----
+SRV*C:\Users\USERNAME\AppData\Local\Temp\SymbolCache*http://msdl.microsoft.com/download/symbols
+----
+* You can now run WinDbg and from the main menu select File > Kernel Debug, then enter the appropriate port number and key. Alternatively you can use the following windbg command line:
++
+----
+windbg -k net:port=NNNN,key=KKKK
+----
+* Checkout the `tools/deploy.bat` and `tools/debug.bat` batch files in the source distribution to see how I deploy and debug WinFsp.
+
+== Debugging a user mode process from kernel mode WinDbg
+
+In order to debug a user mode process from a kernel mode WinDbg session, break into the debugger and issue the following commands:
+
+----
+kd> !gflag +ksl
+kd> sxe ld MODULE-NAME.exe
+----
+
+Restart the debugger and it will break within process creation. You can now set a breakpoint at your process wmain (or main, etc.):
+
+----
+kd> bp MODULE_NAME!wmain
+----
+
+Restart the debugger and it will stop at your program's entry point.

+= Developing File Systems in Kernel Mode
+
+Since release 2019.3 WinFsp supports development of file systems in kernel mode. Such file systems are implemented as kernel drivers that use WinFsp as the primary FSD (File System Driver) as well as the software library that they interface with to retrieve and service file system requests. This document discusses how to write such file systems.
+
+== Motivation
+
+The primary goal of WinFsp is to enable the easy creation of *user mode* file systems using an easy to use API. There are however legitimate reasons for wanting to develop a file system as a *kernel mode* driver, but the difficulty of doing so often deters people because Windows kernel file system development is notoriously difficult and has many pitfalls.
+
+Some of the reasons that a kernel mode file system may be preferrable to a user mode one:
+
+* A kernel driver may be able to achieve better performance than user mode processes.
+* A kernel driver may be able to access advanced OS features that are not easily available to user mode processes.
+* A kernel driver may be able to present an alternative interface than the one presented by WinFsp to user mode processes.
+
+Since release 2019.3 WinFsp supports development of file systems as kernel mode drivers. The primary motivation for this work was to support the https://github.com/billziss-gh/winfuse[WinFuse] project, which exposes the FUSE protocol from the Windows kernel in a way that allows FUSE file systems to interface with it, either directly or via https://github.com/libfuse/libfuse[libfuse]. The support was added in such a way that it is generic enough to be used by other kernel mode file systems.
+
+== Overview
+
+A WinFsp "volume" (file system) is typically created using the `FspFsctlCreateVolume` API. This is simply a wrapper around a `CreateFileW` call on one of the WinFsp control devices, either `WinFsp.Disk` or `WinFsp.Net`. The `CreateFileW` call returns a `HANDLE` to the newly created volume, which acts either as a "disk" or a "network" file system, depending on which control device was used to create it.
+
+User mode file systems interact with the WinFsp FSD via `DeviceIoControl/FSP_FSCTL_TRANSACT` messages on the volume `HANDLE`. (This is usually done indirectly via the WinFsp DLL, which hides this detail behind an easy to use API.)
+
+Since release 2019.3 (v1.5) WinFsp supports the following:
+
+* Registration and on-demand loading of a third party driver when a volume that is destined to be handled by the third party driver is created.
+* Forwarding of custom `DeviceIoControl` messages to a third party driver. This allows the third party driver to handle custom `FSCTL` requests directed to a WinFsp volume `HANDLE`.
+* Kernel-mode API's (called DDI's) that allow a third party driver to register itself with the FSD and interact with its I/O queues.
+
+Such drivers are called within the WinFsp sources and header/library files by the name of "Fsext Providers" (File System Extension Providers). In the text below we will usually refer to them as simply "Providers".
+
+A Provider is a kernel mode driver that uses the FSD as a frontend file system driver to interface with Windows and implement all the complex details that this entails. The Provider fetches I/O requests from the WinFsp I/O queues and may filter them, transform them into a different protocol (as is the case with WinFuse) or use them to fully implement a file system in kernel mode.
+
+== Provider Development
+
+The WinFsp installer includes a "Kernel Developer" feature. When installed this feature adds header and library files in the `opt\fsext` installation subdirectory.
+
+The primary header file used for Provider development is `<winfsp/fsext.h>` and can be found in `opt\fsext\inc`. Additionally the file `<winfsp/fsctl.h>` found in the `inc` installation subdirectory must be in the compiler's include path.
+
+Providers must also be linked with one of the import libraries that can be found in `opt\fsext\lib`. Use the `winfsp-x64.lib` import library when linking the 64-bit version of a Provider and the `winfsp-x86.lib` import library when linking the 32-bit version of a Provider.
+
+=== Provider DDI's
+
+The `<winfsp/fsext.h>` header file includes definitions for the following important DDI's:
+
+* `FspFsextProviderRegister`: This DDI is used by a Provider to register itself with the FSD. Typically the Provider prepares an `FSP_FSEXT_PROVIDER` structure and calls `FspFsextProviderRegister` in its `DriverEntry` routine. The structure's fields are as follows:
+** `Version`: Set to `sizeof(FSP_FSEXT_PROVIDER)`.
+** `DeviceTransactCode`: The `DeviceIoControl` code that should be forwarded to the Provider.
+*** The code must be defined as follows: `CTL_CODE(FILE_DEVICE_FILE_SYSTEM, 0xC00 + ProviderSpecific, METHOD_BUFFERED, FILE_ANY_ACCESS)`.
+*** Please note that this scheme allows for up to 1024 codes. If you want to define a new Provider code I will appreciate it if you email me at `<billziss at navimatics.com>` so that we can keep track of Provider codes, avoid conflicts and see when we need to extend this scheme.
+** `DeviceExtensionSize`: The size of private data that the Provider wants for itself in the `DeviceExtension` of the FSD volume's device object.
+** `DeviceInit`: Called when a new volume is created. The `DeviceObject` parameter is the volume's device object. The `VolumeParams` are the initial parameters passed to `FspFsctlCreateVolume` and can be modified by the Provider.
+** `DeviceFini`: Called when a volume is going away. This usually happens when the volume `HANDLE` is closed.
+** `DeviceExpirationRoutine`: Called once a second as part of the FSD's expiration timer. The FSD uses this timer to expire caches, long-pending IRP's, etc. A Provider can use this call for a similar purpose. The `ExpirationTime` parameter contains the current interrupt time as determined by the FSD.
+** `DeviceTransact`: Called whenever the FSD receives a `DeviceIoControl` request with the `DeviceTransactCode`. The `Irp` parameter contains the relevant `IRP_MJ_FILE_SYSTEM_CONTROL`.
+** `DeviceExtensionOffset`: Set to `0` on input. On successful return from `FspFsextProviderRegister` it will contain the offset to use for accessing the Provider's private data in the `DeviceExtension` of the FSD volume's device object. Given a `DeviceObject`, the data can be accessed as `(PVOID)((PUINT8)DeviceObject->DeviceExtension + Provider.DeviceExtensionOffset)`.
+* `FspFsextProviderTransact`: This DDI is used by a Provider to interact with the FSD I/O queues. The `DeviceObject` is the FSD volume's device object. The `FileObject` is the `FILE_OBJECT` that corresponds to the volume `HANDLE` (created by `FspFsctlCreateVolume`). The `Response` is the response to send and can be `NULL`. The `Request` is a pointer that receives a pointer to a new request from the WinFsp I/O queue and can be `NULL`; if the received pointer is not `NULL` it must be freed with `ExFreePool`.
+
+=== Provider I/O
+
+When the FSD receives a file system IRP it is often able to handle and complete it without help from an external user mode or kernel mode file system. However in most cases the IRP has to be seen and acted upon by an external file system. For this reason the FSD preprocesses the IRP and places it in an I/O queue in the form of a "request". At a later time the external file system retrieves the request, processes it and sends back a "response". The FSD uses the response to locate the original IRP, perform any necessary postprocessing and finally complete the IRP.
+
+Providers typically use the `FspFsextProviderTransact` DDI to receive requests and send back responses. Requests are of type `FSP_FSCTL_TRANSACT_REQ` and responses are of type `FSP_FSCTL_TRANSACT_RSP`. Requests have a `Kind` field which describes what kind of file system operation is being requested. The following request kinds are currently defined in `<winfsp/fsctl.h>`:
+
+```
+    FspFsctlTransactCreateKind,
+    FspFsctlTransactOverwriteKind,
+    FspFsctlTransactCleanupKind,
+    FspFsctlTransactCloseKind,
+    FspFsctlTransactReadKind,
+    FspFsctlTransactWriteKind,
+    FspFsctlTransactQueryInformationKind,
+    FspFsctlTransactSetInformationKind,
+    FspFsctlTransactQueryEaKind,
+    FspFsctlTransactSetEaKind,
+    FspFsctlTransactFlushBuffersKind,
+    FspFsctlTransactQueryVolumeInformationKind,
+    FspFsctlTransactSetVolumeInformationKind,
+    FspFsctlTransactQueryDirectoryKind,
+    FspFsctlTransactFileSystemControlKind,
+    FspFsctlTransactDeviceControlKind,
+    FspFsctlTransactShutdownKind,
+    FspFsctlTransactLockControlKind,
+    FspFsctlTransactQuerySecurityKind,
+    FspFsctlTransactSetSecurityKind,
+    FspFsctlTransactQueryStreamInformationKind,
+```
+
+When request processing is complete the Provider must prepare a response and send it to the FSD using `FspFsextProviderTransact` as mentioned above. It is particularly important that the Provider initializes the `Kind` and `Hint` fields by copying the values from the corresponding request.
+
+This document does not describe in detail how each request kind is supposed to be handled. For the full details refer to the implementation for the WinFsp DLL in the WinFsp sources: `src/dll/fsop.c`. Although this implementation is for user mode file systems, similar logic and techniques should be used for Providers.
+
+== Provider Registration
+
+Providers are loaded on demand and must be properly registered:
+
+* A provider must be registered as a kernel driver. This can be achieved by using the command `sc create PROVIDER type=kernel binPath=X:\PATH\TO\PROVIDER.SYS` or by using the Service Control Manager API's (`OpenServiceW`, `CreateServiceW`, etc.). You do not need an INF file or to use the Setup API in order to register a Provider driver.
+* A provider must be registered under the registry key `HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\WinFsp\Fsext`. Create a string value with name the textual representation of the Provider's transact code (see `DeviceTransactCode`) in `"%08lx"` format and value the Provider's driver name.
+
+For example the WinFuse Provider registers its driver under the name `WinFuse` and adds a registry value of `00093118` -> `WinFuse`.
+
+== Provider Lifetime
+
+Providers are loaded on demand by the FSD during volume creation. This process works as follows:
+
+* During volume creation (e.g. by using `FspFsctlCreateVolume`) a non-zero `FsextControlCode` must be specified in `VolumeParams`.
+* If the FSD sees the `FsextControlCode` as non-zero it attempts to find a corresponding Provider driver.
+** It first checks an internal mapping of codes to Provider drivers. If the code is found, the FSD proceeds to the `DeviceInit` step below.
+** If the code is not found in the internal mapping, the FSD checks the registry under the registry key `HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\WinFsp\Fsext`. If the code is not found the volume creation fails.
+** If the code is found the FSD loads the Provider driver using `ZwLoadDriver`. The Provider is supposed to register itself with the FSD during `DriverEntry` by calling `FspFsextProviderRegister`.
+** Finally the internal mapping of codes to Providers is rechecked. Assuming that everything worked as intended, the corresponding Provider driver is now loaded and we can proceed to the `DeviceInit` step.
+* The FSD proceeds to call the `DeviceInit` callback of the Provider. The Provider can use this call to initialize itself in relation to the new volume device object.
+* Assuming that the volume device object is created successfully, the FSD will do the following:
+** Forward any `FsextControlCode==DeviceTransactCode` requests that it gets in its `IRP_MJ_FILE_SYSTEM_CONTROL` to the Provider via `DeviceTransact`.
+** Call the Provider's `DeviceExpirationRoutine` once a second as part of the FSD's expiration process.
+* Eventually the volume device object will be torn down (e.g. because the corresponding `HANDLE` is closed). In this case the FSD will call the Provider's `DeviceFini` callback.
+
+Finally note that once loaded a Provider driver cannot be unloaded (without a reboot).

+= WinFsp Rebranding
+
+If you have a commercial WinFsp license and wish to produce a rebranded version of WinFsp, you can follow the instructions in this document.
+
+== Overview
+
+The WinFsp build is controlled by the file `build\VStudio\version.properties`. The file contains properties that control the final build output in a number of ways. Some of the properties in this file control how the final build product is branded, others how it is versioned, etc.
+
+=== Branding
+
+The properties that control branding are the following:
+
+* `MyProductName`: This is the overall product name. It should be a short name without spaces. For example: `MyCompanyFSP`. The default value is `WinFsp`.
+
+* `MyProductFileName`: This is the file name that will be used for the primary WinFsp components. For example: if you use `mycompanyfsp` the FSD will be named `mycompanyfsp-x64.sys` and `mycompanyfsp-x86.sys`, the DLL will be named `mycompanyfsp-x64.dll` and `mycompanyfsp-x86.dll`, etc. The default value is `winfsp`. (Note that due to a limitation the WinFsp .NET implementation assumes that `MyProductFileName` is the lowercase version of `MyProductName`.)
+
+* `MyDescription`: This is a longer product description. For example: `MyCompany File System Proxy`. The default value is `Windows File System Proxy`.
+
+* `MyCompanyName`: This is the company name.
+
+* `MyCopyright`: This is the product's copyright.
+
+* `MyFspFsctlDeviceClassGuid`, `MyFspFsvrtDeviceClassGuid`: When creating devices the FSD needs to assign GUID classes to them; it uses the GUIDs specified by these properties. You MUST change these GUIDs when rebranding; otherwise your product and "official" WinFsp releases may interfere with each other. From the Visual Studio main menu use Tools > Create GUID and select option "3. static const struct GUID" to produce GUIDs in the correct format.
+
+=== Versioning
+
+The properties that control versioning are the following:
+
+* `MyCanonicalVersion`: This is the "canonical" (i.e. non-marketing) version of the product. WinFsp uses a `major.minor.build` versioning scheme. The `major.minor` portion of the version comes from this property; build numbers are computed automatically from the current date.
+
+** Some WinFsp components check that canonical versions of different components match. For example, the WinFsp .NET implementation checks that its major version matches the one from the WinFsp DLL.
+
+* `MyProductVersion`: This is the product (i.e. marketing) version of the product. WinFsp uses the release year as the product version; it also adds a point release for subsequent releases (thus 2021 is the first release in 2021, and 2021.1 is the second release, etc). This property may be an arbitrary string.
+
+* `MyProductStage`: This specifies the kind of the build. Allowed values are `Beta`, `RC` (Release Candidate) and `Gold` (Final).
+
+== Limitations
+
+Currently WinFsp supports rebranding of the core WinFsp components:
+
+* The WinFsp FSD (File System Driver).
+
+* The WinFsp DLL (user mode DLL). This includes the DLL import libraries.
+
+* The WinFsp Launcher (Windows service that allows for easy launching of file systems).
+
+Currently WinFsp does not support rebranding of the following components:
+
+* Development files such as header files, samples, etc. These are not end-user visible and therefore are not necessary to be rebranded.
+
+* WinFsp test suites.
+
+* FUSE for Cygwin.
+
+* Chocolatey builds.
+
+Additional limitations:
+
+* The default installer (in file `build\VStudio\installer\Product.wxs`) contains a number of GUIDs. These MUST be changed if the default installer is used by a rebranded product; otherwise installation of your product and "official" WinFsp releases may interfere with each other. There is a Python script at `tools\gensrc\wixguid.py` that can help with this.

+This will instruct the WinFsp Network Provider to request a password from the user prior to starting the file system. This password will then be securely passed to the WinFsp Launcher which in turn will pass it to the user mode file system on its standard input. The user mode file system must respond `OK` if the password is correct and allows access to the user mode file system. Any other response from the user mode file system (including a timeout without a response) is interpreted as an authentication failure.
+
+NOTE: During password entry the user may also choose to "remember" the password in which case it will be saved in the Windows Credential Manager.

 In Release builds the +DEBUGTEST(90)+ macro will evaluate to +TRUE+ and the Cache Manager will be asked directly via +CcCanIWrite+ whether a WRITE should be deferred. In Debug builds the +DEBUGTEST(90)+ macro will evaluate to +FALSE+ sometimes (10% of the time) and the WRITE will be deferred, thus allowing us to test the retry code path.
 
-== Compatibility Testing
+== NTFS Compatibility Testing
 
 WinFsp allows the creation of user mode file systems that exhibit behavior similar to NTFS. This means that Windows applications that use such a file system should not be able to tell the difference between NTFS and the WinFsp-based file system. OTOH specialized applications (such as Defrag) will not work properly on WinFsp file systems.

 WinFsp uses a tool called fsbench for this purpose. Fsbench is able to test specific scenarios, for example: "how long does it take to delete 1000 files?" Fsbench has been very useful for WinFsp and has helped improve its performance: in one situation it helped identify quadratic behavior with the MEMFS ReadDirectory operation, in another situation it helped fine tune the performance of the WinFsp I/O Queue.
 
+== Backwards Compatibility testing
+
+As the WinFsp API's mature it is important to verify that they remain backwards compatible with existing file system binaries. For this purpose binaries that have been compiled against earlier versions of WinFsp are used to verify that they run correctly against the latest version.
+
+For example, in version v1.2B3 of WinFsp an +FSP_FUSE_CAP_STAT_EX+ FUSE extension was introduced. This can change the layout of +struct fuse_stat+ and is therefore a potentially dangerous change. To test against inadvertent breakage a FUSE file system binary that was compiled against v1.2B2 is regularly used to verify backwards compatibility.
+
 == Code Analysis
 
 WinFsp is regularly run under the Visual Studio's Code Analyzer. Any issues found are examined and if necessary acted upon.
