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 _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
