The "standard" and page table walk variants of strncpy_from_user() first check the length of the to be copied string in userspace. The string is then copied to kernel space and the length returned to the caller. However userspace can modify the string at any time while the kernel checks for the length of the string or copies the string. In result the returned length of the string is not necessarily correct. Fix this by copying in a loop which mimics the mvcos variant of strncpy_from_user(), which handles this correctly.
