| |
The first of these patches unifies copy_from_user(), thus making its buffer size checking consistent between 32- and 64-bit.
The second one unifies copy_to_user(), at once adding similar buffer size checking (to help avoiding information leaks).
1: x86: unify copy_from_user() size checking 2: x86: unify copy_to_user() and add size checking to it
