Can we use the attached separate patches with v4.9 and v4.14 ? thanks, -- heikki

If the string was shorter then sizeof(const char *), attempts to read it would have failed with -EOVERFLOW. The problem has been hidden because all build-in string properties have had a string longer then 8 characters until now.
