| |
3.16.57-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Arnd Bergmann <arnd@arndb.de>
commit ade7db991b47ab3016a414468164f4966bd08202 upstream.
This bug was fixed before, but came up again with the latest compiler in another function:
fs/cifs/cifssmb.c: In function 'CIFSSMBSetEA': fs/cifs/cifssmb.c:6362:3: error: 'strncpy' offset 8 is out of the bounds [0, 4] [-Werror=array-bounds] strncpy(parm_data->list[0].name, ea_name, name_len);
Let's apply the same fix that was used for the other instances.
