sys: FspFsvolCreate, FspFsvolSetSecurity: absolute security descriptors

Some third party filters send us security descriptors in absolute rather
than self-relative format. Handle this case by converting them to self-
relative format ourselves.

+
+
+## v2.0 (2023)
+
+This release is a major version change for WinFsp (from 1.x to 2.x). There are no backwards incompatible API changes in this release, but nevertheless enough things change that warrant a version change.
+
+The major new feature of this release is that it allows uninstallation and reinstallation of WinFsp **without reboot**. Going forward installers named `winfsp-2.x.y.msi` can be uninstalled and reinstalled without reboot. Furthermore a later version `winfsp-2.x.y.msi` installer can be used to upgrade over an earlier version `winfsp-2.x.y.msi` installer. However note that a `winfsp-2.x.y.msi` installer cannot be used to upgrade over a legacy `winfsp-1.x.y.msi` installer; you will still need to uninstall the old `winfsp-1.x.y.msi` installer, potentially reboot and then install the new `winfsp-2.x.y.msi` installer.
+
+Changes visible to file system developers are listed below:
+
+- WinFsp executable files are now installed by default in the directory `C:\Program Files (x86)\WinFsp\SxS\sxs.<InstanceID>\bin`. The previous directory `C:\Program Files (x86)\WinFsp\bin` is now a junction that points to the above directory.
+
+- The WinFsp driver name is no longer `winfsp`, but rather a name such as `winfsp+<InstanceID>`. This means that managing the driver using the `sc.exe` utility is no longer as easy.
+
+- The `fsptool` utility has been updated with new commands `lsdrv`, `load`, `unload` and `ver`. The `lsdrv`, `load` and `unload` commands can be used to manage the driver from the command line. This is rarely necessary, but may be useful for troubleshooting purposes.
+
+- Prior to this release the WinFsp driver would never unmount a file system volume unless the user mode file system requested the unmount. From this release onward it is possible for the WinFsp driver to unmount a file system volume, without a user mode file system request. This is to allow for the driver to be unloaded.
+
+    A new operation `DispatcherStopped` has been added to `FSP_FILE_SYSTEM_INTERFACE`, which is sent after the file system volume has been unmounted and the file system dispatcher has been stopped. This can happen because of a user mode file system request via `FspFileSystemStopDispatcher` or because of driver unload. The `DispatcherStopped` operation includes a `Normally` parameter, which is `TRUE` for normal file system shutdown via `FspFileSystemStopDispatcher` and `FALSE` otherwise.
+
+    Native file systems that use the `FspService` infrastructure can use the `FspFileSystemStopServiceIfNecessary` API to handle the `DispatcherStopped` operation (see the MEMFS and NTPTFS samples). FUSE file systems get this functionality for free. .NET file systems that use the `Service` class infrastructure also get this functionality for free.
+
+- WinFsp now offers a .NET library that targets .NET Framework 3.5 (as before) and one that targets .NET Standard 2.0. This is due to work by @Noire001 in PR #451.
+
+    - There is now a winfsp.net nuget package at https://www.nuget.org/packages/winfsp.net
+
+- FUSE now supports path components up to 255 characters long (previously it was 255 bytes). This is due to work by @zeho11 in PR #474.
+
+    - The FUSE passthrough file systems have been updated to support long paths. This is also due to work by @zeho11.
+
+- In some rare circumstances WinFsp file systems could report duplicate directory entries. This problem has been fixed. (GitHub issue #475.)
+
+- The WinFsp symbols directory has been removed. If you are looking for WinFsp symbols you can find them at https://github.com/winfsp/winfsp.sym

+## v1.11 (2022+ARM64)
+
+- [NEW] ARM64 support! For details see [WinFsp on ARM64](https://github.com/winfsp/winfsp/wiki/WinFsp-on-ARM64).
+
+- [NEW] A new file system operation has been added to the FUSE API:
+
+    ```C
+    int (*getpath)(const char *path, char *buf, size_t size,
+        struct fuse_file_info *fi);
+    ```
+
+    The `getpath` operation allows a case-insensitive file system to report the correct case of a file path. For example, `getpath` can be used to report that the actual path of a file opened as `/PATH/TO/FILE` is really `/Path/To/File`. This capability is important for some Windows file system scenarios and can sometimes result in a performance improvement.
+
+- [NEW] New `ntptfs` sample file system. This is a production quality pass through file system and should be used instead of the original `passthrough` file system that was developed for education purposes only.
+
+- [NEW] Many performance improvements:
+
+    - A new `PostDispositionForDirOnly` setting has been added to `FSP_FSCTL_VOLUME_PARAMS`. This allows a file system to declare that it does not want to see `SetInformation/Disposition` requests for files (such requests will still be sent for directories, because a file system is supposed to check if a directory is empty before deletion). This makes file (not directory) deletion faster. This optimization should be safe to enable for most file systems. FUSE file systems get this optimization for free.
+
+    - The FSD now implements "fast I/O" reads and writes. Fast I/O is a technique for doing I/O without using IRP's (I/O Request Packets) and can only work for file systems using the cache manager (`FileInfoTimeout==-1`). This results in significant improvement in read/write scenarios.
+
+    - The FSD now implements "fast I/O" for "transact" messages. Transact messages are used in the communication protocol between the kernel-mode FSD and the user-mode file system. Fast I/O speeds this communication protocol by as much as 10% in some scenarios. (Fast I/O for transact messages is enabled only when using the new `FSP_IOCTL_TRANSACT` control code, but does not require any other special configuration to be enabled.)
+
+    - The FSD per directory cache limit has been increased from 16K to 64K. This should allow for more directory data to be maintained in kernel and reduce round-trips to the user mode file system.
+
+    - The user mode directory buffering mechanism (`FspFileSystemAcquireDirectoryBuffer`) has been improved. The mechanism uses the quick-sort algorithm internally which can exhibit bad performance when sorting already sorted data. The quick-sort algorithm has been improved with the use use of median of three partitioning, which alleviates this problem.
+
+- [NEW] A new registry setting under `HKLM\SOFTWARE\WinFsp` (or `HKLM\SOFTWARE\WOW6432Node\WinFsp` on a 64-bit system) called `MountBroadcastDriveChange` has been introduced, which if set to 1 will broadcast an additional "drive change" message to all top-level windows (including Explorer) during mounting and unmounting.
+
+    - Normally the Windows infrastructure broadcasts a `WM_DEVICECHANGE` message whenever a drive gets added/removed. In some rare systems it is possible for this message to get lost or stalled. The workaround for these rare systems is to enable this registry setting, in which case WinFsp will broadcast the `WM_DEVICECHANGE` using a slightly different but more reliable method than the one Windows uses.
+
+    - For more details see source code comments at [`FspMountBroadcastDriveChange`](https://github.com/winfsp/winfsp/blob/v1.11B3/src/dll/mount.c#L390-L406).
+
+- [FIX] The WinFsp Network Provider now implements `NPGetUniversalName`. This fixes problems with some apps (e.g. Photos app).
+
+- [FIX] WinFsp-FUSE now supports Azure AD accounts when specifying the `-o uid=-1` option. In addition a new option `-o uidmap=UID:SID` allows the specification of arbitrary UID<->SID or UID<->UserName mappings.
+
+- [FIX] All executables (`*.exe,*.dll,*.sys`) in the WinFsp installation `bin` folder are now signed.
+
+- [FIX] The default value for the registry setting `DistinctPermsForSameOwnerGroup` has been changed from 0 to 1.
+
+- [BUILD] Product configuration (`MyProductName`, etc.) is done by the file `build.version.props` located in `build\VStudio`. This file was previously named `version.properties`.
+
+
+## v1.11RC1 (2022+ARM64 RC1)
+
+- [NEW] ARM64 support! For details see [WinFsp on ARM64](https://github.com/winfsp/winfsp/wiki/WinFsp-on-ARM64).

+
+## v1.11B3 (2022+ARM64 Beta3)
+
+- [NEW] ARM64 support! For details see [WinFsp on ARM64](https://github.com/winfsp/winfsp/wiki/WinFsp-on-ARM64).
+
+- [NEW] A new file system operation has been added to the FUSE API:
+
+    ```C
+    int (*getpath)(const char *path, char *buf, size_t size,
+        struct fuse_file_info *fi);
+    ```
+
+    The `getpath` operation allows a case-insensitive file system to report the correct case of a file path. For example, `getpath` can be used to report that the actual path of a file opened as `/PATH/TO/FILE` is really `/Path/To/File`. This capability is important for some Windows file system scenarios and can sometimes result in a performance improvement.
+
+- [NEW] New `ntptfs` sample file system. This is a production quality pass through file system and should be used instead of the original `passthrough` file system that was developed for education purposes only.
+
+- [NEW] Many performance improvements:
+
+    - A new `PostDispositionForDirOnly` setting has been added to `FSP_FSCTL_VOLUME_PARAMS`. This allows a file system to declare that it does not want to see `SetInformation/Disposition` requests for files (such requests will still be sent for directories, because a file system is supposed to check if a directory is empty before deletion). This makes file (not directory) deletion faster. This optimization should be safe to enable for most file systems. FUSE file systems get this optimization for free.
+
+    - The FSD now implements "fast I/O" reads and writes. Fast I/O is a technique for doing I/O without using IRP's (I/O Request Packets) and can only work for file systems using the cache manager (`FileInfoTimeout==-1`). This results in significant improvement in read/write scenarios.
+
+    - The FSD now implements "fast I/O" for "transact" messages. Transact messages are used in the communication protocol between the kernel-mode FSD and the user-mode file system. Fast I/O speeds this communication protocol by as much as 10% in some scenarios. (Fast I/O for transact messages is enabled only when using the new `FSP_IOCTL_TRANSACT` control code, but does not require any other special configuration to be enabled.)
+
+    - The FSD per directory cache limit has been increased from 16K to 64K. This should allow for more directory data to be maintained in kernel and reduce round-trips to the user mode file system.
+
+    - The user mode directory buffering mechanism (`FspFileSystemAcquireDirectoryBuffer`) has been improved. The mechanism uses the quick-sort algorithm internally which can exhibit bad performance when sorting already sorted data. The quick-sort algorithm has been improved with the use use of median of three partitioning, which alleviates this problem.
+
+- [NEW] A new registry setting under `HKLM\SOFTWARE\WinFsp` (or `HKLM\SOFTWARE\WOW6432Node\WinFsp` on a 64-bit system) called `MountBroadcastDriveChange` has been introduced, which if set to 1 will broadcast an additional "drive change" message to all top-level windows (including Explorer) during mounting and unmounting.
+
+    - Normally the Windows infrastructure broadcasts a `WM_DEVICECHANGE` message whenever a drive gets added/removed. In some rare systems it is possible for this message to get lost or stalled. The workaround for these rare systems is to enable this registry setting, in which case WinFsp will broadcast the `WM_DEVICECHANGE` using a slightly different but more reliable method than the one Windows uses.
+
+    - For more details see source code comments at [`FspMountBroadcastDriveChange`](https://github.com/winfsp/winfsp/blob/v1.11B3/src/dll/mount.c#L390-L406).

-## Benefits
+## Overview
 
-### Stability
+WinFsp is a platform that provides development and runtime support for custom file systems on Windows computers. Typically any information or storage may be organized and presented as a file system via WinFsp, with the benefit being that the information can be accessed via the standand Windows file API’s by any Windows application.
 
-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).
+The core WinFsp consists of a kernel mode file system driver (FSD) and a user mode DLL. The FSD interfaces with the Windows kernel and handles all interactions necessary to present itself as a file system driver. The DLL interfaces with the FSD and presents an API that can be used to handle file system functions. For example, when an application attempts to open a file, the file system receives an `Open` call with the necessary information.
 
-### Performance
+Using WinFsp to build a file system has many benefits:
 
-WinFsp outperforms its competition and in many scenarios performs as well as NTFS. Read more about its [Performance](doc/WinFsp-Performance-Testing.asciidoc).
+**Easy development**: Developing kernel mode file systems for Windows is a notoriously difficult task. WinFsp makes file system development relatively painless. This [Tutorial](doc/WinFsp-Tutorial.asciidoc) explains how to build a file system.
+
+**Stability**: Stable software without any known kernel mode crashes, 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).
+
+**Correctness**: Strives for file system correctness and compatibility with NTFS. For details see the [Compatibility](doc/NTFS-Compatibility.asciidoc) document.
+
+**Performance**: Has excellent performance that rivals or exceeds that of NTFS in many file system scenarios. Read more about its [Performance](doc/WinFsp-Performance-Testing.asciidoc).

     <img src="doc/WinFsp-Performance-Testing/rdwr_tests.png" height="300"/>
 </p>
 
-### Compatibility
+**Wide support**: Supports Windows 7 to Windows 11 and the x86, x64 and ARM64 architectures.
 
-WinFsp strives for compatibility with NTFS and file system correctness. For the full details see the [Compatibility](doc/NTFS-Compatibility.asciidoc) document.
+**Flexible API**: Includes Native, FUSE2, FUSE3 and .NET API's.
 
-### Easy to Use
+**Shell integration**: Provides facilities to integrate user mode file systems with the Windows shell. See the [Service Architecture](doc/WinFsp-Service-Architecture.asciidoc) document.
 
-WinFsp has an easy to use but comprehensive API.
+**Self-contained**: Self-contained software without external dependencies.
 
-* 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)

+You can test WinFsp by launching MEMFS from the command line:
 
-## Building and Running
+```
+billziss@xps ⟩ ~ ⟩ net use X: \\memfs64\test
+The command completed successfully.
 
-In order to build WinFsp you will need the following:
+billziss@xps ⟩ ~ ⟩ X:
+billziss@xps ⟩ X:\ ⟩ echo "hello world" > hello.txt
+billziss@xps ⟩ X:\ ⟩ dir
 
-* 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:
+    Directory: X:\
 
-    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/).

-WinFsp is designed to run on Windows 7 and above. It has been tested on the following platforms:
 
-* Windows 7 Enterprise
-* Windows 8 Pro
-* Windows Server 2012
-* Windows 10 Pro
-* Windows Server 2016

-## How to Help
+MEMFS (and all file systems that use the WinFsp Launcher as documented in the [Service Architecture](doc/WinFsp-Service-Architecture.asciidoc) document) can also be launched from Explorer using the "Map Network Drive" functionality.
 
-I am looking for help in the following areas:
+## Resources
 
-* If you have a file system that runs on FUSE please consider porting it to WinFsp. WinFsp has a native API, but it also has a FUSE (high-level) API.
-* If you are working with a language other than C/C++ (e.g. Delphi, Java, etc.) and you are interested in porting/wrapping WinFsp I would love to hear from you.
-* There are a number of outstanding issues listed in the [GitHub repository](https://github.com/billziss-gh/winfsp/issues). Many of these require knowledge of Windows kernel-mode and an understanding of the internals of WinFsp so they are not for the faint of heart.
+**Documentation**:
 
-In all cases I can provide ideas and/or support.
+- [Tutorial](doc/WinFsp-Tutorial.asciidoc)
 
-## Where to Discuss
+- [API Reference](doc/WinFsp-API-winfsp.h.md)
 
-If you wish to discuss WinFsp there are now two options:
+- [Building](doc/WinFsp-Building.asciidoc)
+
+- [Project wiki](https://github.com/winfsp/winfsp/wiki)

+
+            For example, if the DLL location is `C:\Program Files (x86)\WinFsp\bin\winfsp-x64.dll`:
+
+            - Combining with the path "." will produce the original DLL location:
+                `C:\Program Files (x86)\WinFsp\bin\winfsp-x64.dll`
+
+            - Combining with the path "..\\NetworkProvider.dll" will produce:

 - 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?::

 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.

 - 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 Building
+
+This document provides instructions on building WinFsp and describes the WinFsp project structure.
+
+== Building
+
+In order to build WinFsp you will need the following:
+
+* Visual Studio 2019
+* Windows Driver Kit (WDK)
+* https://wixtoolset.org[Wix toolset]
+
+Use the command `tools\build.bat Release` to produce a full build (including the installer). However the resulting product will not be properly signed and Windows will refuse to load the WinFsp driver, unless you enable testsigning with `bcdedit -set testsigning on`.
+
+Producing a fully functional build requires an EV certificate and a Partner Center for Windows Hardware account. Assuming you have those, the steps to produce a full build are as follows:
+
+* Produce a build signed with your EV certificate using `tools\build.bat Release`.
+* Upload the signed `driver.cab` file to Microsoft for "attestation signing".
+* Download the now Microsoft-signed `driver.cab` file and extract it into a folder (e.g. `signed-drivers`).
+* Re-run the build using `tools\build.bat Release PATH\TO\signed-drivers`
+
+== Versioning
+
+WinFsp versioning (and branding) is controlled by the file `build\VStudio\build.version.props`. See the link:WinFsp-Rebranding.asciidoc[WinFsp Rebranding] document for details.

+= 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).

-This document discusses performance testing for WinFsp. The goal of this performance testing is to discover optimization opportunities for WinFsp and compare its performance to that of NTFS and Dokany.
+This document presents results from performance testing of WinFsp. These results show that WinFsp has excellent performance that rivals or exceeds that of NTFS in many file system scenarios. Some further optimization opportunities are also identified.

-This performance testing shows that WinFsp has excellent performance in all tested scenarios. It outperforms NTFS in most scenarios (an unfair comparison as NTFS is a disk file system and WinFsp is tested with an in-memory file system). It also outperforms Dokany in all scenarios, often by an order of magnitude.
+Two reference WinFsp file systems, MEMFS and NTPTFS, are compared against NTFS in multiple file system scenarios. MEMFS is an in-memory file system, whereas NTPTFS (NT passthrough file system) is a file system that passes all file system requests onto an underlying NTFS file system.

+The important takeaways are:
 
-== Fsbench
+- MEMFS is faster than NTFS is most scenarios. This is a somewhat expected result because MEMFS is an in-memory file system, whereas NTFS is a disk file system. However it shows that WinFsp does not add significant overhead and user mode file systems can be fast.
 
-All testing was performed using a new performance test suite developed as part of WinFsp, called https://github.com/billziss-gh/winfsp/blob/master/tst/fsbench/fsbench.c[fsbench]. Fsbench was developed because it allows the creation of tests that are important to file system developers; for example, it can answer questions of the type: "how long does it take to delete 1000 files" or "how long does it take to list a directory with 10000 files in it".
+- MEMFS and NTPTFS both outperform NTFS when doing cached file I/O! This is a significant result because doing file I/O is the primary purpose of a file system. It is also an unexpected result at least in the case of NTPTFS, since NTPTFS runs on top of NTFS.
 
-Fsbench is based on the https://github.com/billziss-gh/winfsp/tree/master/ext/tlib[tlib] library, originally from the *secfs* project. Tlib is usually used to develop regression test suites in C/C++, but can be also used to create performance tests. 
+The following sections present the testing methodology used, provide instructions for independent verification, describe the individual tests in detail and provide an explanation for the observed results.
 
-Fsbench currently includes the following tests:

-== Tested File Systems
+== Methodology
 
-=== NTFS
+A test run consists of performance tests run one after the other (in sequence). The test driver is careful to clear system caches before each test to minimize timing interference between the tests (because we would not want operations performed in test A to affect measurements of test B). Tests are run on an idle computer to minimize interference from third party components.
 
-The comparison to NTFS is very important to establish a baseline. It is also very misleading because NTFS is a disk file system and MEMFS (either the WinFsp or Dokany variants) is an in memory file system. The tests will show that MEMFS is faster than NTFS. This should not be taken to mean that we are trying to make the (obvious) claim that an in memory file system is faster than a disk file system, but to show that the approach of writing a file system in user mode is a valid proposition and can be efficient.
+Each test run is run a number of times (default: 3) against each file system and the smallest time value for the particular test and file system is chosen. The assumption is that even in a seemingly idle system there is some activity that affects the results; the smallest value is the preferred one to use because it reflects the time when there is less or no other system activity.
 
-=== WinFsp/MEMFS
+For the NTFS file system we use the default configuration as it ships with Windows (e.g. 8.3 names are enabled). For the NTPTFS file system we disable anti-virus checks on the lower file system, because it makes no sense for NTPTFS to pay for virus checking twice. (Consider an NTPTFS file system that exposes a lower NTFS directory `C:\t` as an upper drive `X:`. Such a file system would have virus checking applied on file accesses to `X:`, but also to its own accesses to `C:\t`. This is unnecessary and counter-productive.)
 
-MEMFS is the file system used to test WinFsp and shipped as a sample bundled with the WinFsp installer. MEMFS is a simple in memory file system and as such is very fast under most conditions. This is desirable because our goal with this performance testing is to measure the speed of the WinFsp system components rather the performance of a complex user mode file system. MEMFS has minimal overhead and is ideal for this purpose.
+Note that the sequential nature of the tests represents a worst case scenario for WinFsp. The reason is that a single file system operation may require a roundtrip to the user mode file system and such a roundtrip requires two process context switches (i.e. address space and thread switches): one context switch to carry the file system request to the user mode file system and one context switch to carry the response back to the originating process. WinFsp performs better when multiple processes issue file system operations concurrently, because multiple requests are queued in its internal queues and multiple requests can be handled in a single context switch.
 
-WinFsp/MEMFS can be run in different configurations, which enable or disable WinFsp caching features. The tested configurations were:

-- An infinite FileInfoTimeout, which enables caching of metadata and data.
-- A FileInfoTimeout of 1s (second), which enables caching of metadata but disables caching of data.
-- A FileInfoTimeout of 0, which completely disables caching.

-The WinFsp git commit at the time of testing was d804f5674d76f11ea86d14f4bcb1157e6e40e719.
-
-=== Dokany/MEMFS
-
-To achieve fairness when comparing Dokany to WinFsp the MEMFS file system has been ported to Dokany. Substantial care was taken to ensure that WinFsp/MEMFS and Dokany/MEMFS perform equally well, so that the performance of the Dokany FSD and user-mode components can be measured and compared accurately.
-
-The Dokany/MEMFS project has its own https://github.com/billziss-gh/memfs-dokany[repository]. The project comes without a license, which means that it may not be used for any purpose other than as a reference.
-
-The Dokany version used for testing was 1.0.1. The Dokany/MEMFS git commit was 27a678d7c0d5ee2fb3fb2ecc8e38210857ae941c.
-
-== Test Environment
-
-Tests were performed on an idle computer/VM. There was a reboot of both the computer and VM before each file system was tested. Each test was run twice and the smaller time value chosen. The assumption is that even in a seemingly idle desktop system there is some activity which will affect the results; the smaller value is the preferred one to use because it reflects the time when there is less or no other activity.
-
-The test environment was as follows:

-== Test Results
+== Results
 
-In the graphs below we use consistent coloring to quickly identify a file system. Red is used for NTFS, yellow for WinFsp/MEMFS with a FileInfoTimeout of 0, green for WinFsp/MEMFS with a FileInfoTimeout of 1, light blue for WinFsp/MEMFS with an infinite FileInfoTimeout and deep blue for Dokany/MEMFS.
+In the charts below we use consistent coloring and markers to quickly identify a file system. Blue and the letter 'N' is used for NTFS, orange and the letter 'M' is used for MEMFS, green and the letter 'P' is used for NTPTFS.
+
+In bar charts shorter bars are better. In plot charts lower times are better. (Better means that the file system is faster).
 
-In all tests lower times are better (the file system is faster).
 
 === File Tests
 
-These tests measure the performance of creating, opening, overwriting and listing files and directories.
+File tests are tests that are performed against the hierarchical path namespace of a file system. These tests measure the performance of creating, opening, overwriting, listing and deleting files.
+
+Measured times for these tests are normalized against the NTFS time (so that the NTFS value is always 1). This allows for easy comparison between file systems across all file tests.
+
+MEMFS has the best performance in most of these tests. NTFS performs better in some tests; these are discussed further below. NTPTFS is last as it has the overhead of both NTFS and WinFsp.
+

 ==== file_create_test
 
-This test measures the performance of CreateFileW(CREATE_NEW) / CloseHandle. WinFsp has the best performance here. Dokany follows and NTFS is last as it has to actually update its data structures on disk.
+This test measures the performance of creating new files using `CreateFileW(CREATE_NEW)` / `CloseHandle`. MEMFS has the best performance here, while NTFS has worse performance as it has to update its data structures on disk.

+image::WinFsp-Performance-Testing/file_create_test.png[]
 
 ==== file_open_test
 
-This test measures the performance of CreateFileW(OPEN_EXISTING) / CloseHandle. WinFsp again has the best (although uneven) performance, followed by NTFS and then Dokany.
+This test measures the performance of opening different files using `CreateFileW(OPEN_EXISTING)` / `CloseHandle`. MEMFS again has the best performance, followed by NTFS and then NTPTFS.
 
-WinFsp appears to have very uneven performance here. In particular notice that opening 1000 files is slower than opening 2000 files, which makes no sense! I suspect that the test observes an initial acquisition of resouces when the test first starts, which is not necessary when the test runs for 2000 files at a later time. This uneven performance should probably be investigated in the future.

+==== iter.file_open_test
+
+This test measures the performance of opening the same files repeatedly using `CreateFileW(OPEN_EXISTING)` / `CloseHandle`. NTFS has the best performance, with MEMFS following and NTPTFS a distant third.
+
+This test shows that NTFS does a better job than WinFsp when re-opening a file. The problem is that in most cases the WinFsp API design requires a round-trip to the user mode file system when opening a file. Improving WinFsp performance here would likely require substantial changes to the WinFsp API.

 ==== file_overwrite_test
 
-This test measures the performance of CreateFileW(CREATE_ALWAYS) / CloseHandle. WinFsp is fastest, followed by NTFS and then Dokany.
+This test measures the performance of overwriting files using `CreateFileW(CREATE_ALWAYS)` / `CloseHandle`. MEMFS is fastest, followed by NTFS and then NTPTFS.

+image::WinFsp-Performance-Testing/file_overwrite_test.png[]
 
 ==== file_list_test
 
-This test measures the performance of FindFirstFileW / FindNextFile / FindClose. NTFS wins this scenario, likely because it can satisfy the list operation from cache. WinFsp has overall good performance. Dokany appears to show slightly quadratic performance in this scenario.
+This test measures the performance of listing files using `FindFirstFileW` / `FindNextFile` / `FindClose`. MEMFS is again fastest with NTFS and NTPTFS following.

-ifndef::env-browser[image::WinFsp-Performance-Testing/file_list_test.png[]]
+It should be noted that NTFS can perform better in this test, if 8.3 (i.e. short) names are disabled (see `fsutil 8dot3name`). However Microsoft ships NTFS with 8.3 names enabled by default and these tests are performed against the default configuration of NTFS.
+
+image::WinFsp-Performance-Testing/file_list_test.png[]
+
+==== file_list_single_test
+
+This test measures the performance of listing a single file using `FindFirstFileW` / `FindNextFile` / `FindClose`. NTFS has again best performance, with MEMFS following and NTPTFS a distant third.
+
+This test shows that NTFS does a better job than WinFsp at caching directory data. Improving WinFsp performance here would likely require a more aggressive and/or intelligent directory caching scheme than the one used now.
+
+image::WinFsp-Performance-Testing/file_list_single_test.png[]
 
 ==== file_delete_test
 
-This test measures the performance of DeleteFileW. WinFsp has the best performance, followed by Dokany and NTFS with very similar performance.
+This test measures the performance of deleting files using `DeleteFileW`. MEMFS has the best performance, followed by NTFS and NTPTFS.

 === Read/Write Tests
 
-These tests measure the performance of cached, non-cached and memory-mapped I/O.
+Read/write tests are tests that measure the performance of cached, non-cached and memory-mapped I/O.
 
-==== rdwr_cc_write_page_test
+Measured times for these tests are normalized against the NTFS time (so that the NTFS value is always 1). This allows for easy comparison between file systems across all read/write tests.
 
-This test measures the performance of cached WriteFile with 1 page writes. NTFS and WinFsp with an infinite FileInfoTimeout have the best performance, with a clear edge to NTFS (likely because of its use of FastIO, which WinFsp does not currently support). WinFsp with a FileInfoTimeout of 0 or 1 performance is next, because WinFsp does not use the NTOS Cache Manager in this scenario. Dokany performance is last.
+MEMFS and NTPTFS outperform NTFS in cached and non-cached I/O tests and have equal performance to NTFS in memory mapped I/O tests. This result may be somewhat counter-intuitive (especially for NTPTFS), but the reasons are explained below.
 
-ifdef::env-browser[chart::line[data-uri="WinFsp-Performance-Testing/rdwr_cc_write_page_test.csv",file="WinFsp-Performance-Testing/rdwr_cc_write_page_test.png",opt="x-label=iterations,y-label=time"]]
-ifndef::env-browser[image::WinFsp-Performance-Testing/rdwr_cc_write_page_test.png[]]
+image::WinFsp-Performance-Testing/rdwr_tests.png[]
 
 ==== rdwr_cc_read_page_test
 
-This test measures the performance of cached ReadFile with 1 page reads. The results here are very similar to the rdwr_cc_write_page_test case and similar comments apply.
+This test measures the performance of cached `ReadFile` with 1 page reads. MEMFS and NTPTFS outperform NTFS by a considerable margin.
 
-ifdef::env-browser[chart::line[data-uri="WinFsp-Performance-Testing/rdwr_cc_read_page_test.csv",file="WinFsp-Performance-Testing/rdwr_cc_read_page_test.png",opt="x-label=iterations,y-label=time"]]
-ifndef::env-browser[image::WinFsp-Performance-Testing/rdwr_cc_read_page_test.png[]]
+Cached reads are satisfied from cache and they can effectively be a "memory copy" from the operating system's buffers into the `ReadFile` buffer. Both WinFsp and NTFS implement NT "fast I/O" and one explanation for the test's result is that the WinFsp "fast I/O" implementation is more performant than the NTFS one.
 
-==== rdwr_nc_write_page_test
+An alternative explanation is that MEMFS and NTPTFS are simply faster in filling the file system cache when a cache miss occurs. While this may be true for MEMFS (because it maintains file data in user mode memory), it cannot be true for NTPTFS. Recall that the test driver clears system caches prior to running every test, which means that when NTPTFS tries to fill its file system cache for the upper file system, it has to access lower file system data from disk (the same as NTFS).
 
-This test measures the performance of non-cached WriteFile with 1 page writes. WinFsp has the best performance, followed by Dokany. NTFS shows bad performance, which of course make sense as we are asking it to write all data to the disk.

+This test measures the performance of non-cached `ReadFile` with 1 page reads. Although MEMFS and NTPTFS have better performance than NTFS, this result is not as interesting, because MEMFS is an in-memory file system and NTPTFS currently implements only cached I/O (this may change in the future). However we include this test for completeness.

-==== mmap_write_test
+==== rdwr_nc_write_page_test
 
-This test measures the performance of memory mapped writes. NTFS and WinFsp seem to have identical performance here, which actually makes sense because memory mapped I/O is effectively always cached and most of the actual I/O is done asynchronously by the system.
