Subject: Re: [PATCH 1/1] Drivers: hv: Implement the file copy service
Date: Thu, 9 Jan 2014 23:09:21 +0300 [thread overview]
Message-ID: <20140109200921.GT30234@mwanda> (raw)

We've had this discussion before where you urge me to trust the host...
Problem: This code is racy.
Solution: The host will only send one message at a time.
Now I have to audit the user space code on the host and I don't feel
like doing that so you win.
I wish we had a better way to do IPC. If kdbus were ready, that might
have worked for this, and it's a better solution because both sender and
reciever code will be written in a less trusting way.
regards,
dan carpenter
