scsi: storvsc: Add validation for untrusted Hyper-V values
For additional robustness in the face of Hyper-V errors or malicious behavior, validate all values that originate from packets that Hyper-V has sent to the guest. Ensure that invalid values cannot cause data being copied out of the bounds of the source buffer when calling memcpy. Ensure that outgoing packets do not have any leftover guest memory that has not been zeroed out. Link: https://lore.kernel.org/r/20200706160928.53049-1-lkmlabelt@gmail.com Cc: James E.J.
