That’s a good point. There are some checks before hand when we validate the
ioctl command, where we check for a “minimum size” for the output buffer. The
parameter #3 to MapIrpOutputBuffer() is a “required length”. Pls. let me know
if I need to add more checks.

case OVS_IOCTL_READ_EVENT:
case OVS_IOCTL_READ_PACKET:
/*
* Output buffer is mandatory. These IOCTLs are used to read events and
* packets respectively. It is convenient to have separate ioctls.
*/
if (outputBufferLen != 0) {
status = MapIrpOutputBuffer(irp, outputBufferLen,
sizeof *ovsMsg, &outputBuffer);
