Subject: [PATCH 123/201] mdadm: Monitor.c fix coverity issues
|
|
|
|
Fixing the following coding errors the coverity tools found:
|
|
|
|
* Event check_return: Calling "fcntl(fd, 2, 1)" without checking
|
|
return value. This library function may fail and return an error code.
|
|
|
|
* Dereferencing "sl", which is known to be "NULL".
|
|
|
|
* Event fixed_size_dest: You might overrun the 32-character fixed-size
|
|
string "devnm" by copying "tmp" without checking the length.
|
