There is no security problem here. The user is allowed to choose either v1 or v3. Using a double read race condition to choose v1 is not going to cause problems. It's slightly more complicated than just choosing it directly but that doesn't make it a security issue. It's a bit like typing with your feet in that just because using your toes instead of your fingergs is more complicated, it doesn't make it a security issue. regards, dan carpenter _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
