update changelog

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

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

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

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

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

+
+* [FSD] A fix regarding concurrency of READs on the same file: WinFsp was supposed to allow concurrent READ requests on the same file (e.g. two concurrent overlapped `ReadFile` requests on the same `HANDLE`) to be handled concurrently by the file system; unfortunately due to a problem in recent versions of WinFsp READ requests on the same file were serialized. This problem has now been fixed. See GitHub issue #291 for more details.

+* [FIX] Work around an incompatibility with Avast Antivirus.
+** Native and .NET file systems that experience this problem should set the flag `RejectIrpPriorToTransact0` in `FSP_FSCTL_VOLUME_PARAMS` to `1`. This is only required when mounting on a directory with Avast Antivirus present.

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