Revision ebfddb3d447f5267c76680ea4d242e6f9bcafa87 authored by Arnd Bergmann on 13 September 2017, 23:28:23 UTC, committed by Linus Torvalds on 14 September 2017, 01:53:15 UTC
gcc points out a minor bug in the handling of unknown cookie types, which could result in a string overflow when the integer is copied into a 3-byte string: fs/fscache/object-list.c: In function 'fscache_objlist_show': fs/fscache/object-list.c:265:19: error: 'sprintf' may write a terminating nul past the end of the destination [-Werror=format-overflow=] sprintf(_type, "%02u", cookie->def->type); ^~~~~~ fs/fscache/object-list.c:265:4: note: 'sprintf' output between 3 and 4 bytes into a destination of size 3 This is currently harmless as no code sets a type other than 0 or 1, but it makes sense to use snprintf() here to avoid overflowing the array if that changes.
