tools: build: sign cab file using SHA-256

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] Official Windows 11 support.
+
+* [NEW] WinFsp has had its Delete functionality redesigned in release 2021.1 Beta3. This redesign unifies all Windows file deletion semantics under a single file system operation that also supports the new POSIX semantics introduced in Windows 10 Redstone 1. The new Delete design is recommended for new file systems, however existing file systems will continue to work without any changes. See https://github.com/billziss-gh/winfsp/wiki/WinFsp-Delete-Redesign for more information.
+
+* [NEW] Support for `FileDispositionInformationEx` and `FileRenameInformationEx` has been added (see above).
+
+* [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 capability `FSP_FUSE_CAP_DELETE_ACCESS`. If this capability is specified WinFsp will call the FUSE `access` method with the WinFsp-specific flag `FSP_FUSE_DELETE_OK` to check whether the deletion should be allowed. This can be used to disallow deletion of files and directories that would normally be allowed under the FUSE/POSIX model.
+
+* [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.
+
+* [NEW] A new registry setting under `HKLM\SOFTWARE\WinFsp` (or `HKLM\SOFTWARE\WOW6432Node\WinFsp` on a 64-bit system) called `MountDoNotUseLauncher` has been introduced, which if set to 1 will disable the use of the Launcher during mounting. The default value is 0 which allows the use of the Launcher during mounting in those rare cases when necessary. (In general the Launcher is not necessary for mounting. However when running a file system in the Windows Service context (session 0) under an account that is not LocalSystem (e.g. `NT AUTHORITY\NETWORK SERVICE`), the Launcher is used to create global drives.)
+
+* [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] The FSD will now report a file's reparse tag in the `EaSize` field of `FILE_FULL_DIR_INFORMATION` and friends. This fixes problems such as `cmd.exe` not recognizing symlinks in a `dir` command. (See GitHub issue #380.)
+
+* [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] Fixed a potential problem when launching file system instances using the Launcher. (See GitHub issue #356.)
+
+* [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.)

+* [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.)

+
+* [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

+* [FIX] Fix how rename target directories are opened (use `FILE_DIRECTORY_FILE`). (See PR #270. Thanks @hammerg.)
+
+
+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.)

+
+
+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.
+* [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.

     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.

 In order to build WinFsp you will need the following:
 
-* 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)
 
 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:
 
     tools\build.bat CONFIGURATION
 
-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 on`. For more information see this [document](http://www.secfs.net/winfsp/develop/debug/).

+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.

-The core WinFsp layer always supported multiple file systems in the same process either simultaneously or one after another. However this was not the case with WinFsp-FUSE (i.e. the FUSE layer of WinFsp) prior to version 2018.2 B2. This limitation has been rectified as of WinFsp 2018.2 B2.
+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.)

 == Unsupported features
 
 WinFsp does not support the following NTFS features:
 
 - Hard links. Rather rarely used on Windows. However it might be worthwhile to implement them for WinFsp.
-- Extended attributes. Although popular with POSIX file systems, they are severely hampered and rarely used on Windows. They are also not exposed via the Win32 API.
 - Short file names. Short file names are a relic of the past. WinFsp made a conscious decision not to support them.
 - Paging files. Providing paging file support via a user mode file system is impossible for a number of reasons.
 - Object ID's. Opening files by ID (+FILE_OPEN_BY_FILE_ID+) is not supported.

+= 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.

+= WinFsp Delete Redesign
+
+WinFsp has had its Delete functionality redesigned in release 2021.1 Beta3. This redesign unifies all Windows file deletion semantics under a single file system operation that also supports the new POSIX semantics introduced in Windows 10 Redstone 1. The new Delete design is recommended for new file systems, however existing file systems will continue to work without any changes.
+
+== Background
+
+In this section we discuss how file deletion worked in Windows traditionally as well as the changes introduced in recent versions of Windows 10.
+
+=== Traditional File Deletion
+
+The traditional method for deleting a file or directory on Windows involves the following steps:
+
+- Open the file using https://docs.microsoft.com/en-us/windows-hardware/drivers/ddi/ntifs/nf-ntifs-ntopenfile[`NtOpenFile`] (or equivalent) with `DELETE` access.
+- Set the "disposition" flag on the file handle using https://docs.microsoft.com/en-us/windows-hardware/drivers/ddi/ntifs/nf-ntifs-ntsetinformationfile[`NtSetInformationFile`] with `FileDispositionInformation`. This only marks the file for deletion and does not delete the file.
+- Close the file using https://docs.microsoft.com/en-us/windows-hardware/drivers/ddi/ntifs/nf-ntifs-ntclose[`NtClose`] (or equivalent). Provided that there are no other open handles to the file, the file is actually deleted at this stage.
+
+This is the method that https://docs.microsoft.com/en-us/windows/win32/api/fileapi/nf-fileapi-deletefilew[`DeleteFileW`] and https://docs.microsoft.com/en-us/windows/win32/api/fileapi/nf-fileapi-removedirectoryw[`RemoveDirectoryW`] use to delete a file or directory.
+
+An alternative method involves the `FILE_DELETE_ON_CLOSE` flag:
+
+- Open the file using https://docs.microsoft.com/en-us/windows-hardware/drivers/ddi/ntifs/nf-ntifs-ntopenfile[`NtOpenFile`] (or equivalent) with the `FILE_DELETE_ON_CLOSE` option.
+- Close the file using https://docs.microsoft.com/en-us/windows-hardware/drivers/ddi/ntifs/nf-ntifs-ntclose[`NtClose`] (or equivalent). Provided that there are no other open handles to the file, the file is actually deleted at this stage.
+
+This alternative method does not set the disposition flag and therefore does not have chance to perform any associated checks. An important disposition flag check is whether a directory is empty: attempting to remove a non-empty directory using `FILE_DELETE_ON_CLOSE` will fail silently, because there is no way to communicate a file deletion error from `NtClose`.
+
+In order to better understand those scenarios let's examine what happens within the kernel and the file system driver (FSD).
+
+When the kernel receives a file API call such as `NtOpenFile`, it packages the call arguments into a data structure called an "I/O Request Packet" (IRP) and forwards it to the appropriate FSD. Each IRP contains a field that describes its function, for example, `IRP_MJ_CREATE` for `NtOpenFile` and `IRP_MJ_SET_INFORMATION` for `NtSetInformationFile`.
+
+With this knowledge we can now examine what happens in the `DeleteFileW` / `RemoveDirectoryW` scenario:
+
+- Open the file using `NtOpenFile`: The kernel creates an https://docs.microsoft.com/en-us/windows-hardware/drivers/ifs/irp-mj-create[`IRP_MJ_CREATE`] IRP, places inside it a newly created https://docs.microsoft.com/en-us/windows-hardware/drivers/ddi/wdm/ns-wdm-_file_object[`FILE_OBJECT`] and forwards it to the FSD. If opening the file succeeds, the kernel will also create a `HANDLE` that is used to refer to this `FILE_OBJECT`; if opening the file fails, this `FILE_OBJECT` will be destroyed.
+- Set the "disposition" flag on the file handle using `NtSetInformationFile` with `FileDispositionInformation`: The kernel creates an https://docs.microsoft.com/en-us/windows-hardware/drivers/ifs/irp-mj-set-information[`IRP_MJ_SET_INFORMATION`] IRP and passes the `FileDispositionInformation` information in it. The FSD performs some checks (e.g. if a directory is empty) and if they succeed it marks the file for deletion.
+- Close the file using `NtClose`: The kernel creates an https://docs.microsoft.com/en-us/windows-hardware/drivers/ifs/irp-mj-cleanup[`IRP_MJ_CLEANUP`] IRP, which denotes that all ``HANDLE``s that refer to a `FILE_OBJECT` are closed. (It is possible to have multiple ``HANDLE``s to the same `FILE_OBJECT` by using an API such as https://docs.microsoft.com/en-us/windows/win32/api/handleapi/nf-handleapi-duplicatehandle[`DuplicateHandle`].) The FSD checks and if this is the last `FILE_OBJECT` cleaned up for the file and if the file is marked for deletion, it deletes the file. Traditionally there was no way to return an error from `IRP_MJ_CLEANUP`.
+- Notice that while the file is closed from the perspective of user mode, it is not closed from the perspective of kernel mode. The kernel and the FSD maintain both a handle count and a reference count for the `FILE_OBJECT`. When the handle count goes to `0` then an `IRP_MJ_CLEANUP` IRP is issued (see above). When the reference count goes to `0` then a different https://docs.microsoft.com/en-us/windows-hardware/drivers/kernel/irp-mj-close[`IRP_MJ_CLOSE`] IRP is issued to the FSD. This signifies to the FSD that the `FILE_OBJECT` is going away and the file is fully closed (including from the kernel perspective). There is no way to return an error from `IRP_MJ_CLOSE`.
+
+The situation is similar in the `FILE_DELETE_ON_CLOSE` scenario, with the important difference that the FSD marks the file for deletion immediately upon receiving the `IRP_MJ_CREATE` IRP and that it never receives the `IRP_MJ_SET_INFORMATION` IRP. As before the actual deletion happens in `IRP_MJ_CLEANUP` and only when the last `HANDLE` to the file is closed.
+
+Some important takeaways:
+
+- It is possible for a file to already be open when a `DeleteFileW` / `RemoveDirectoryW` (or equivalent sequence of `NtOpenFile`, `NtSetInformationFile`, `NtClose`, etc.) is executed. This means that the file may NOT be deleted upon return from the `DeleteFileW` / `RemoveDirectoryW` call even though these API's report success. **Traditionally a successful return from `DeleteFileW` / `RemoveDirectory` signifies only that the file or directory has been successfully marked for deletion and not that it has been deleted!**
+- The `NtClose` call does not return error codes from `IRP_MJ_CLEANUP`. This means that it is impossible for user mode to know whether a file marked for deletion was deleted or not.
+- The `FILE_OBJECT` remains valid even after a file has been deleted in `IRP_MJ_CLEANUP`. It is therefore possible to receive additional I/O (e.g. read/write) on the file. Many Windows file systems (including at least some versions of NTFS) do not handle this case very well.
+
+=== File Deletion in Recent Versions of Windows 10
+
+In Windows 10 Redstone 1 Microsoft introduced the `FileDispositionInformationEx` information class. This new information class can be used to request POSIX semantics for file deletion during the `NtSetInformationFile` call. POSIX semantics for file deletion mean that when a file is deleted any open handles to it remain valid and can be used for I/O such as read/write.
+
+Some time later (unclear exactly when) Microsoft changed the `DeleteFileW` / `RemoveDirectoryW` API's to use the `FileDispositionInformationEx` information class and only if this fails (e.g. because the file system is not capable) fall back to the old `FileDispositionInformation` information class. With this change `DeleteFileW` and `RemoveDirectoryW` actually delete the file or directory rather than simply mark it for deletion. (This change is in general a good thing, but can create incompatibility problems for applications that expect the traditional behavior.)
+
+Let's examine the `DeleteFileW` / `RemoveDirectoryW` scenario again:
+
+- Open the file using `NtOpenFile`: The kernel creates an https://docs.microsoft.com/en-us/windows-hardware/drivers/ifs/irp-mj-create[`IRP_MJ_CREATE`] IRP, places inside it a newly created https://docs.microsoft.com/en-us/windows-hardware/drivers/ddi/wdm/ns-wdm-_file_object[`FILE_OBJECT`] and forwards it to the FSD. If opening the file succeeds, the kernel will also create a `HANDLE` that is used to refer to this `FILE_OBJECT`; if opening the file fails, this `FILE_OBJECT` will be destroyed.
+- Intruct the file system to delete the file with POSIX semantics using `NtSetInformationFile` with `FileDispositionInformationEx`. The kernel creates an https://docs.microsoft.com/en-us/windows-hardware/drivers/ifs/irp-mj-set-information[`IRP_MJ_SET_INFORMATION`] IRP and passes the `FileDispositionInformationEx` information in it. The FSD performs some checks (e.g. if a directory is empty) and if they succeed it deletes the file or directory (as opposed to simply mark it for deletion).
+- Close the file using `NtClose`. The kernel creates an https://docs.microsoft.com/en-us/windows-hardware/drivers/ifs/irp-mj-cleanup[`IRP_MJ_CLEANUP`] IRP, which denotes that all ``HANDLE``s that refer to a `FILE_OBJECT` are closed. The FSD has already deleted the file and does not need to do anything else.
+- As before an `IRP_MJ_CLOSE` IRP will also be sent to the FSD eventually.
+
+Notice that the actual file deletion happens during `NtSetInformationFile` and the return code from this API reports on the success or failure of the file deletion. Thus we no longer have the problems discussed earlier and `DeleteFileW` / `RemoveDirectoryW` correctly report whether the file was deleted or not.
+
+== WinFsp Support for POSIX Unlink
+
+WinFsp gained support for POSIX Unlink (`FileDispositionInformationEx`) and POSIX Rename (`FileRenameInformationEx`) in release 2021.1 Beta3. To enable this support a native or .NET file system must set the `SupportsPosixUnlinkRename` flag when the file system is created. FUSE file systems have this flag enabled by default (but can be disabled with the command line option `-o LegacyUnlinkRename`).
+
+The POSIX Unlink support spurred some changes in the WinFsp native and .NET API's with regards to file deletion. The WinFsp FUSE layer transparently supports these changes.
+
+Prior to release 2021.1 Beta3, user mode file systems handled file deletion by implementing `CanDelete` / `SetDelete` to check the file disposition flag and `Cleanup` with the `FspCleanupDelete` flag to perform the actual file deletion. From release 2021.1 Beta3 forward the recommended method is to use the new `Delete` file system operation to handle all aspects of file deletion.
+
+The new `Delete` operation follows the general pattern below:
+
+[source,c]
+----
+NTSTATUS Delete(FSP_FILE_SYSTEM *FileSystem,
+    PVOID FileContext, PWSTR FileName, ULONG Flags)
+{
+    switch (Flags)
+    {
+    case FILE_DISPOSITION_DO_NOT_DELETE:
+        // set file disposition flag: do not delete file at Cleanup time
+
+    case FILE_DISPOSITION_DELETE:
+        // set file disposition flag: delete file at Cleanup time
+
+    case FILE_DISPOSITION_DELETE | FILE_DISPOSITION_POSIX_SEMANTICS:
+        // delete file now; open handles to file remain valid
+
+    case -1:
+        // delete file now; called during Cleanup time
+
+    default:
+        return STATUS_INVALID_PARAMETER;
+    }
+}
+----
+
+As can be seen the `Delete` operation handles marking (`FILE_DISPOSITION_DELETE`) and unmarking (`FILE_DISPOSITION_DO_NOT_DELETE`) a file for deletion, performing file deletion with POSIX semantics (`FILE_DISPOSITION_DELETE | FILE_DISPOSITION_POSIX_SEMANTICS`) and performing file deletion with traditional Windows semantics (`-1`). If the Delete operation is defined it is used instead of `CanDelete` / `SetDelete` and `Cleanup` with the `FspCleanupDelete` flag, even if these operations are also defined.
+
+A sensible implementation of `Delete` might look something similar to the following:
+
+[source,c]
+----
+NTSTATUS Delete(FSP_FILE_SYSTEM *FileSystem,
+    PVOID FileContext, PWSTR FileName, ULONG Flags)
+{
+    switch (Flags)
+    {
+    case FILE_DISPOSITION_DO_NOT_DELETE:
+        return STATUS_SUCCESS;
+
+    case FILE_DISPOSITION_DELETE:
+        if (IsNotEmptyDirectory(FileSystem, FileContext))
+            return STATUS_DIRECTORY_NOT_EMPTY;
+        return STATUS_SUCCESS;
+
+    case FILE_DISPOSITION_DELETE | FILE_DISPOSITION_POSIX_SEMANTICS:
+    case -1:
+        if (IsNotEmptyDirectory(FileSystem, FileContext))
+            return STATUS_DIRECTORY_NOT_EMPTY;
+        return RealDeleteFileOrDirectory(FileSystem, FileContext);
+
+    default:
+        return STATUS_INVALID_PARAMETER;
+    }
+}
+----

+= 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.
