3.3-stable review patch. If anyone has any objections, please let me know.
------------------ From: Anton Tikhomirov <[email protected]> commit 27a78d6a283d6782438f72306746afe4bf44c215 upstream. It's wrong to use the size of array as an argument for strncat. Memory corruption is possible. strlcat is exactly what we need here.
