Subject: [PATCH] mdopen: Prevent overrunning the devname buffer when copying
|
|
|
7bdf8f |
devnm into it for long md names.
|
|
|
7bdf8f |
|
|
|
7bdf8f |
Linux allows for 32 character device names. When using the maximum
|
|
|
7bdf8f |
size device name and also storing "/dev/", devname needs to be 37
|
|
|
7bdf8f |
character long to store the complete device name.
|
|
|
7bdf8f |
i.e. "/dev/md_abcdefghijklmnopqrstuvwxyz12\0"
