I want to share a buffer between a UM-service and a kernel driver.
I know that we can use Direct IO, but the problem with that is that i want them to be able to write to this buffer at any time without the need of IOCTLs, both of them can read and write to this buffer.
My questions are:
What is the best way to implement this?
What is the best way to synchronize them, so they wouldn't be writing/reading the content at the same time?
Which of them should create the buffer? UM service using something malloc, or kernel mode driver by using something ExAllocatePool? Any difference?
