In function ‘copy_from_user’, inlined from ‘dgrp_net_ioctl’ at drivers/staging/dgrp/dgrp_net_ops.c:3408:21: arch/x86/include/asm/uaccess_32.h:211:26: error: call to ‘copy_from_user_overflow’ declared with attribute error: copy_from_user() buffer size is not provably correct Signed-off-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
