tools: build.bat: make cab file from unsigned drivers

On Windows/ARM64 CreateFileW is no longer able to create directories
using the flags FILE_FLAG_BACKUP_SEMANTICS | FILE_FLAG_POSIX_SEMANTICS.
The new FspCreateDirectoryFileW implements the same semantics and replaces
the previous CreateFileW call.

+
+## v1.12.22339 (2022.2 Update1)
+
+*Note: This release (`v1.12.22339`) is the same as the previous release (`v1.12`) except that: (1) the kernel-mode drivers are now digitally signed only with the Microsoft Attestation signature, and that: (2) no release assets are digitally signed with SHA-1. (This change was necessary to fix a problem in older versions of Windows such as Windows 7.)*
+
+- [NEW] WinFsp now supports mounting as directory using the Mount Manager. Use the syntax `\\.\C:\Path\To\Mount\Directory`.
+
+- [NEW] A new registry setting `MountUseMountmgrFromFSD` has been added. See [WinFsp Registry Settings](https://github.com/winfsp/winfsp/wiki/WinFsp-Registry-Settings) for details.
+
+- [FIX] A problem with Windows containers has been fixed. (GitHub issue #438.)
+
+- [FIX] File systems can now be mounted as directories on ARM64. (GitHub issue #448.)
+

+
+
+## 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)

-## 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.

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

+hello world
+billziss@xps ⟩ X:\ ⟩ cd ~
+billziss@xps ⟩ ~ ⟩ net use X: /delete
+X: was deleted successfully.
 ```
-* [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:
+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.
 
-    tools\build.bat CONFIGURATION
+## Resources
 
-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](doc/WinFsp-Debugging-Setup.asciidoc).
+**Documentation**:
 
-WinFsp is designed to run on Windows 7 and above. It has been tested on the following platforms:
+- [Tutorial](doc/WinFsp-Tutorial.asciidoc)
 
-* Windows 7 Enterprise
-* Windows 8 Pro
-* Windows Server 2012
-* Windows 10 Pro
-* Windows Server 2016
+- [API Reference](doc/WinFsp-API-winfsp.h.md)
 
-## How to Help
+- [Building](doc/WinFsp-Building.asciidoc)
 
-I am looking for help in the following areas:
+- [Project wiki](https://github.com/winfsp/winfsp/wiki)
 
-* 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.
-
-In all cases I can provide ideas and/or support.

+            - MyNpRegisterPath: Network Provider registration path
+            - MyEventLogRegisterPath: Event Log registration path
+
+            These paths are assumed to be relative to the location of the WinFsp DLL during
+            registration: during DLLRegisterServer the DLL uses PathCombineW to combine its own
+            location with these paths to produce the final locations to be used for registration.
+
+            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:
+                `C:\Program Files (x86)\WinFsp\bin\NetworkProvider.dll`
+
+            - For Network Provider registrations only it is allowed to use environment variables
+            in the path. For example combining the above DLL location with the path
+            "..\\NetworkProvider-\x25PROCESSOR_ARCHITECTURE\x25.dll" will produce:
+                `C:\Program Files (x86)\WinFsp\bin\NetworkProvider-%PROCESSOR_ARCHITECTURE%.dll`
+
+            (Note that the \x25 escape sequence must be used otherwise the VS build system will
+            try to interpret the string %PROCESSOR_ARCHITECTURE% as an environment variable during
+            the build.)

 == 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 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.
+
+== Project Structure
+

+= 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.

 = Performance Testing
-:caption:
 
-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.
 
-== Executive Summary
+== Summary
 
-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 test results are summarized in the charts below.

-== 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.

-== 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:

-In the graphs below we use consistent coloring to quickly identify a file system.

+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.
+
+image::WinFsp-Performance-Testing/file_tests.png[]
 
 ==== 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.

 ==== 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.

-ifndef::env-browser[image::WinFsp-Performance-Testing/file_open_test.png[]]
+==== 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.

 ==== 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.

+
+==== 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.

 === 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. The results here are very similar to the rdwr_nc_write_page_test case and similar comments apply.
+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.
+This test measures the performance of non-cached `WriteFile` with 1 page writes. Again MEMFS and NTPTFS have better performance than NTFS, but similar comments as for `rdwr_nc_read_page_test` apply.

+= 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\build.version.props`. 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.

+
+* `InstallDir (REG_SZ)`: Contains the WinFsp installation directory.
+
+* `DistinctPermsForSameOwnerGroup (REG_DWORD)`: Directs how WinFsp-FUSE should consider UNIX owner and group permissions in the case when the Windows owner and group SID are the same (for example, this can happen when someone uses a Microsoft account as their primary login). When this setting is 0 and the Windows owner and group SID are the same, WinFsp-FUSE combines the UNIX owner and group permissions (for example, user permission `rw-` and group permission `---` combine to `---`), which can result in inadvertent "access denied" errors. When this setting is 1 and even if the Windows owner and group SID are the same, WinFsp-FUSE looks at the UNIX owner permissions and the UNIX group permissions separately. The default value is 1 since v1.11B1 and was 0 in earlier versions.
+
+* `MountBroadcastDriveChange (REG_DWORD)`: A value of 1 instructs WinFsp to broadcast an additional "drive change" message to all top-level windows during mounting and unmounting. The default value is 0. 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.
+
+* `MountDoNotUseLauncher (REG_DWORD)`: A value of 1 disallows the use of the Launcher for drive mounting. The default value of 0 allows use of the Launcher for drive mounting 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.
+
+* `MountUseMountmgrFromFSD (REG_DWORD)`: A value of 1 instructs WinFsp to use the Mount Manager from the FSD (File System Driver) which runs in kernel mode. The default value of 0 instructs WinFsp to use the Mount Manager from the DLL which runs in user mode. Using the Mount Manager from user mode requires Administrator access and this setting allows a file system to circumvent the Administrator access requirement. This setting is not recommended for general use.

+= WinFsp on ARM64
+
+This document summarizes the changes made to WinFsp to support Windows on ARM64. With these changes WinFsp runs natively in the ARM64 environment, while maintaining backwards compatibility.
+
+== Build System
+
+* Visual Studio 2019 or later is required to build WinFsp. Visual Studio 2015 builds are no longer possible because of lack of ARM64 support.
+** The script `tools\gensrc\remove-build-arm64.bat` can be used to remove the ARM64 configuration from the project files. This allows WinFsp to be built with Visual Studio 2015, but without ARM64 support. This is a hack to support AppVeyor builds on Server 2012 images that have only Visual Studio 2015 installed.
+* Build configuration is now done by the file `build.common.props` located in `build\VStudio`.
+* Product configuration (`MyProductName`, etc.) is done by the file `build.version.props` located in `build\VStudio`. This file was previously named `version.properties`.
+* Project files under `build\VStudio` have been updated to support ARM64 builds.

+* The macros `FSP_FSCTL_PRODUCT_FULL_REGKEY` and `FSP_FSCTL_PRODUCT_FILE_ARCH` have been added to header file `inc\winfsp\fsctl.h`:
+** `FSP_FSCTL_PRODUCT_FULL_REGKEY`: The full registry path for WinFsp.
+** `FSP_FSCTL_PRODUCT_FILE_ARCH`: The expected computer architecture suffix to use for file names (`a64` for ARM64, `x64` for x64, `x86` for x86).
+
+== File System Driver
+
+* The `IoInitializeTimer`, `IoStartTimer` and `IoStopTimer` DDI's are missing from Windows on ARM64 (https://social.msdn.microsoft.com/Forums/en-US/e1f4dbbd-a3f1-40a4-8f8b-e12a04b1b074/is-iostarttimer-universal[link]). The same functionality is now implemented within WinFsp in file `src\sys\devtimer.c`
+* The FSD (and other WinFsp components) used a number of memory barriers primarily for the purpose of lock-free access of certain variables. Most of these memory barriers have been removed and replaced with "interlocked" loads/stores so that any such accesses would continue to be correct under ARM64, which has weaker consistency guarantees than x86/x64. The new `FspInterlocked*` calls are implemented in `inc/winfsp/fsctl.h` and are used by both kernel and user mode code.
+
+== Samples
+
+* The sample project files have been updated to support ARM64 builds.
+
+== Installer
+
+* The installer has been retrofitted to support native installation on ARM64, x64 and x86 environments.
+* The installer remains a single MSI file that supports all architectures.
+** NOTE: The current technique for detecting OS architecture relies on reading the registry value `PROCESSOR_ARCHITECTURE` from key `HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment`. This may be fragile and a better technique may be required.
+* Files are installed in `\Program Files (x86)\WinFsp` on ARM64 and x64 Windows and `\Program Files` on x86 Windows.
+* Registry settings are placed in `HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\WinFsp` on ARM64 and x64 Windows and `HKEY_LOCAL_MACHINE\SOFTWARE\WinFsp` on x86 Windows.
+* Files for all architectures are always installed regardless of OS architecture. For example, all of `winfsp-a64.dll`, `winfsp-x64.dll` and `winfsp-x86.dll` are found in the `bin` subdirectory on ARM64, x64 and x86 Windows.
+* WinFsp supports x86 file systems on x86 Windows, x86 and x64 file systems on x64 Windows and x86, x64 and ARM64 file systems on ARM64 Windows.
+
+== License
+
+* The special exception for FLOSS to GPLv3 has been updated to mention that linking to `winfsp-a64.dll` is also allowed.

+
+v1.10 (2022)::
+
+Changes since v1.9:
+
+* [NEW] Official Windows 11 support.
+
+* [NEW] Support for `FileDispositionInformationEx` and `FileRenameInformationEx` has been added. Native and .NET file systems must enable this support by setting `SupportsPosixUnlinkRename` in `FSP_FSCTL_VOLUME_PARAMS`. FUSE file systems have this support enabled by default, but they can disable it by using the `-o LegacyUnlinkRename` command line option.
+
+* [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.)
+
+* [NEW] A new sample memfs-fuse file system written in C++ has been added. This file system uses all FUSE2 features offered by WinFsp-FUSE, passes all file system tests (that can be passed by a FUSE2 file system) and will act as the reference WinFsp-FUSE file system going forward.
+
+* [FIX] Fixed a problem with `FspFileSystemReadDirectoryBuffer` and file systems that support pattern matching (like passthrough). (GitHub issue #351.)
+
+* [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] Improved symlink support for FUSE file systems. Notably:
+
+** FUSE file systems now support converting a directory to a symlink reparse point.
+
+** The determination of whether a symlink is a file or directory (necessary because the Windows file system makes this distinction) is now possible for file systems that do not support slashdot (`/.`) queries. (A slashdot query is one like `getattr("/PATH/.")`; such queries are not normally expected to be resolved by FUSE file systems.)
+
+* [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.)

+= 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/ifs/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;
+    }
+}
+----

+
+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.
+
+== Executive Summary
+
+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.

+
+== Fsbench
+
+All testing was performed using a new performance test suite developed as part of WinFsp, called https://github.com/winfsp/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".
+
+Fsbench is based on the https://github.com/winfsp/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.
+
+Fsbench currently includes the following tests:

+
+== Tested File Systems
+
+=== NTFS
+
+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.
+
+=== WinFsp/MEMFS

+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.
+
+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:
+----
+MacBook Pro (Retina, 13-inch, Early 2015)
+3.1 GHz Intel Core i7
+16 GB 1867 MHz DDR3
+500 GB SSD
+
+VirtualBox Version 5.0.20 r106931
+1 CPU
+4 GB RAM
+80 GB Dynamically allocated differencing storage
+
+Windows 10 (64-bit) Version 1511 (OS Build 10586.420)
+----
+
+== Test 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 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_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.

+ifndef::env-browser[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.
+
+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.

+ifndef::env-browser[image::WinFsp-Performance-Testing/file_open_test.png[]]
+
+==== file_overwrite_test
+
+This test measures the performance of CreateFileW(CREATE_ALWAYS) / CloseHandle. WinFsp is fastest, followed by NTFS and then Dokany.
+

+ifndef::env-browser[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.

+
+==== file_delete_test
+
+This test measures the performance of DeleteFileW. WinFsp has the best performance, followed by Dokany and NTFS with very similar performance.
+
+ifdef::env-browser[chart::line[data-uri="WinFsp-Performance-Testing/file_delete_test.csv",file="WinFsp-Performance-Testing/file_delete_test.png",opt="x-label=file count,y-label=time"]]

+
+=== Read/Write Tests
+
+These tests measure the performance of cached, non-cached and memory-mapped I/O.
+
+==== rdwr_cc_write_page_test
+
+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.

+ifndef::env-browser[image::WinFsp-Performance-Testing/rdwr_cc_write_page_test.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.
+
+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[]]
+
+==== rdwr_nc_write_page_test
+
+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.
+
+ifdef::env-browser[chart::line[data-uri="WinFsp-Performance-Testing/rdwr_nc_write_page_test.csv",file="WinFsp-Performance-Testing/rdwr_nc_write_page_test.png",opt="x-label=iterations,y-label=time"]]
+ifndef::env-browser[image::WinFsp-Performance-Testing/rdwr_nc_write_page_test.png[]]

+ifndef::env-browser[image::WinFsp-Performance-Testing/rdwr_nc_read_page_test.png[]]
+
+==== mmap_write_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.
+
+There are no results for Dokany as it seems to (still) not support memory mapped files:
+
+----
+Y:\>c:\Users\billziss\Projects\winfsp\build\VStudio\build\Release\fsbench-x64.exe --mmap=100 mmap*

+ifndef::env-browser[image::WinFsp-Performance-Testing/mmap_write_test.png[]]
+
+==== mmap_read_test
+
+This test measures the performance of memory mapped reads. Again NTFS and WinFsp seem to have identical performance here.
+
+There are no results for Dokany as it faces the same issue as with mmap_write_test.
