fs/ufs/inode.c:817: warning: array subscript is above array bounds

["d binderman" <dcb314@hotmail.com>]

Hello there,

I just tried to compile Linux kernel 2.6.19.2 with the
new GNU C compiler version 4.3 snapshot 20070126.

The compiler said

fs/ufs/inode.c:817: warning: array subscript is above array bounds

The source code is

       for (i = 0; i < (UFS_NDADDR + UFS_NINDIR); i++)
           ufs_inode->ui_u2.ui_addr.ui_db[i] = ufsi->i_u1.i_data[i];

but

./include/linux/ufs_fs.h:                       __fs32  ui_db[UFS_NDADDR];/* 
0x28 data blocks */
./include/linux/ufs_fs.h:                       __fs64     
ui_db[UFS_NDADDR]; /* 112: Direct disk blocks. */

and

       __fs32  i_data[15];

and

#define UFS_NDADDR 12
#define UFS_NINDIR 3

so the kernel seems to be trying to write fifteen bytes into an array only 
twelve
bytes in size. Suggest code rework.


Regards

David Binderman
