R. Silva <gustavoars@kernel.org> # Date: Fri Jul 14 13:56:37 2023 -0600 # # fs: omfs: Use flexible-array member in struct omfs_extent # # Memory for 'struct omfs_extent' and a 'e_extent_count' number of extent # entries is indirectly allocated through 'bh->b_data', which is a pointer # to data within the page. This implies that the member 'e_entry' # (which is the start of extent entries) functions more like an array than # a single object of type 'struct omfs_extent_entry'. # # So we better turn this object into a proper array, in this case a # flexible-array member, and with that, fix the following # -Wstringop-overflow warning seen after building s390 architecture with # allyesconfig (GCC 13): # # fs/omfs/file.c: In function 'omfs_grow_extent': # include/linux/fortify-string.h:57:33: warning: writing 16 bytes into a region of size 0 [-Wstringop-overflow=] # 57 \| #define __underlying_memcpy __builtin_memcpy # \| ^ # include/linux/fortify-string.h:648:9: note: in expansion of macro '__underlying_memcpy' # 648 \| __underlying_##op(p, q, __fortify_size); \ # \| ^~~~~~~~~~~~~ # include/linux/fortify-string.h:693:26: note: in expansion of macro '__fortify_memcpy_chk' # 693 \| #define memcpy(p, q, s) __fortify_memcpy_chk(p, q, s, \ # \| ^~~~~~~~~~~~~~~~~~~~ # fs/omfs/file.c:170:9: note: in expansion of macro 'memcpy' # 170 \| memcpy(terminator, entry, sizeof(struct omfs_extent_entry)); # \| ^~~~~~ # In file included from fs/omfs/omfs.h:8, # from fs/omfs/file.c:11: # fs/omfs/omfs_fs.h:80:34: note: at offset 16 into destination object 'e_entry' of size 16 # 80 \| struct omfs_extent_entry e_entry; /* start of extent entries */ # \| ^~~~~~~ # # There are some binary differences before and after changes, but this are # expected due to the change in the size of 'struct omfs_extent' and the # necessary adjusments. # # This helps with the ongoing efforts to globally enable # -Wstringop-overflow. # # Link: https://github.com/KSPP/linux/issues/330 # Reviewed-by: Kees Cook <keescook@chromium.org> # Signed-off-by: Gustavo A.
