mdadm: Specify enough length when write to buffer
|
|||
|
|
|
|||
|
|
In Detail.c the buffer path in function Detail is defined as path[200],
|
|||
|
|
in fact the max lenth of content which needs to write to the buffer is
|
|||
|
|
287. Because the length of dname of struct dirent is 255.
|
|||
|
|
During building it reports error:
|
|||
|
|
error: ‘%s’ directive writing up to 255 bytes into a region of size 189
|
|||
|
|
[-Werror=format-overflow=]
|
|||
|
|
|
|||
|
|
In function examine_super0 there is a buffer nb with length 5.
|
|||
|
|
But it need to show a int type argument. The lenght of max
|
|||
|
|
number of int is 10. So the buffer length should be 11.
|
|||
|
|
|
|||
|
|
In human_size function the length of buf is 30. During building
|
|||
|
|
there is a error:
|
|||
|
|
output between 20 and 47 bytes into a destination of size 30.
|
|||
|
|
Change the length to 47.
