2015-11-24ControlDevice: Do not process AddRedirect in IoInCallerContextDmitry Fleytman4-29/+97
This commit moves processing of AddRedirect IOCTL from IoInCallerContext callback of control device to normal default queue DeviceIoControl callback. This change eliminates posibility for parallel execution of AddRedirect and other operations, particularly RemoveRedirect. Initially AddRedirect was perfomed in IoInCallerContext callback to open user mode handle to the device being redirected in context of correct user mode process. This patch achieves the same goal by storing caller's process handle in request context in IoInCallerContext callback and duplicating handle to the original calling process from queue's DeviceIoControl callback.

2015-10-28UsbDk: Perform ReadPipe/WritePipe via IOCTLsDmitry Fleytman11-187/+159
This commit fixes issues with accessing USB devices on some USB host controllers. Before this fix UsbDk assumed IO type NEITHER for ReadFile/WriteFile operations performed on captured USB device. This assumption is not true in some cases because UsbDk creates filter devices which use the same IO type as device being filtered, i.e. IO type is effectively defined by USB host controller driver. While some host controllers work in NEITHER IO mode, others use DIRECT IO instead. When capturing device plugged into such a controller UsbDk failed to retrieve ReadFile/WriteFile buffers because there are different API used different IO types and UsbDk used the wrond one. This patch changes UsbDk DLL/Driver interface to use IOCTL for ReadPipe/WritePipe operations. Since IO type for IOCTL requests is determined by IOCTL code and not by target device settings UsbDk need not consider IO type used by the host controller being filtered.
