SMB server sends malformed responses on error
The SMB2 dispatch code can emit partially constructed responses if a request handler returns SDRC_ERROR. This is easily observed over WireShark when running the WPTS (Windows Protocol Test Suites). One particular test case shows this very clearly: the InvalidCreateRequestStructureSize test found in the CreateClose section. Attached is a packet capture showing this.
