Userspace can alter the string after the kernel has run strlen_user(). Also: the strlen_user() return value includes the \0, so fix that. Also: handle EFAULT from strlen_user(). It's unlikely anyone is using this code. Very, very unlikely. If I remember correctly, CONFIG_HPUX turns this code on, but one would actually need CONFIG_BINFMT_SOM to load a binary that could cause a problem, and BINFMT_SOM has had an #error in it for quite some time.
