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)
In-Reply-To: <540ecdf5cf6b47d79583f4f97788e3f0@BY2PR03MB299.namprd03.prod.outlook.com>

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
