Bug when creating MdlAddress, with memory leaks #196

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
http://code.google.com/p/dokan/source/browse/trunk/sys/dokan.c?r=171#551

erroneously declared a local variable

PMDL mdl = IoAllocateMdl(Irp->UserBuffer, Length, FALSE, FALSE, Irp);
if (mdl == NULL) {
  DDbgPrint("    IoAllocateMdl returned NULL\n");
  return STATUS_INSUFFICIENT_RESOURCES;
}

and forget about it

I think need to be replaced like this

Irp->MdlAddress = IoAllocateMdl(Irp->UserBuffer, Length, FALSE, FALSE, Irp);
if (Irp->MdlAddress == NULL) {
  DDbgPrint("    IoAllocateMdl returned NULL\n");
  return STATUS_INSUFFICIENT_RESOURCES;
}
