+VOID ( *DispatcherStopped)(

+**Parameters**
+
+- _FileSystem_ \- The file system on which this request is posted.
+- _Normally_ \- TRUE if the file system is being stopped via FspFileSystemStopDispatcher.
+FALSE if the file system is being stopped because of another reason such
+as driver unload/uninstall.
+
+**Discussion**
+
+Prior to WinFsp v2.0 the FSD would never unmount a file system volume unless
+the user mode file system requested the unmount. Since WinFsp v2.0 it is possible
+for the FSD to unmount a file system volume without an explicit user mode file system
+request. For example, this happens when the FSD is being uninstalled.
+
+A user mode file system can use this operation to determine when its dispatcher
+has been stopped. The Normally parameter can be used to determine why the dispatcher
+was stopped: it is TRUE when the file system is being stopped via
+FspFileSystemStopDispatcher and FALSE otherwise.
+
+When the file system receives a request with Normally == TRUE it need not take any
+extra steps. This case is the same as for pre-v2.0 versions: since the file system
+stopped the dispatcher via FspFileSystemStopDispatcher, it will likely exit its
+process soon.
+
+When the file system receives a request with Normally == FALSE it may need to take
+extra steps to exit its process as this is not done by default.
+
+A file system that uses the FspService infrastructure may use the
+FspFileSystemStopServiceIfNecessary API to correctly handle all cases.
+
+This operation is the last one that a file system will receive.

Bill Zissimopoulos	ae40f0edb1	sys: FspFastIoDeviceControl: fix exploit reported by Tay Kiat Loong The WinFsp "transact" protocol is used by user mode file systems to interface with the FSD. This protocol works via the DeviceIoControl API and uses the FSP_IOCTL_TRANSACT control code. The FSP_IOCTL_TRANSACT code is marked as METHOD_BUFFERED. When the DeviceIoControl call is forwarded as an IRP, the METHOD_BUFFERED flag instructs the kernel to copy user mode buffers to kernel mode buffers (and vice-versa). However when the DeviceIoControl call is forwarded via the FastIO mechanism the METHOD_BUFFERED flag is ignored. This means that when WinFsp added support for DeviceIoControl FastIO, the FSD started accessing user mode buffers directly. This means that a malicious file system could attempt exploits like changing or freeing a buffer while the FSD is reading it. Tay Kiat Loong developed a POC exploit which demonstrated this vulnerability. This commit fixes the problem by patching FspFastIoDeviceControl to add the missing METHOD_BUFFERED handling.	2026-02-17 15:21:35 +02:00
