| Subject: sparc64: make string buffers large enough |
| |
| From: Dan Carpenter <dan.carpenter@oracle.com> |
| |
| commit b5c3206190f1fddd100b3060eb15f0d775ffeab8 upstream. |
| |
| My static checker complains that if "lvl" is ULONG_MAX (this is 64 bit) |
| then some of the strings will overflow. I don't know if that's possible |
| but it seems simple enough to make the buffers slightly larger. |
