The Linux kernel d_path() function converts a dentry structure into an ASCII path name. The full path to the specified dentry is returned in a fixed length buffer of size PAGE_SIZE bytes.
|
|
|
|
Reportedly, if a dentry structure is passed with a path which would exceed this length, an erroneous value is returned. The path which is returned has leading entries truncated, and no error is reported.
