Subject: [PATCH 01/11] ima: qualify pathname in audit info record
|
|
|
|
Adding new field (mount namespace id, along with already existent file
|
|
inode and device name) to uniquely identify a pathname considering
|
|
different mount namespaces. The file inode on a given device is unique
|
|
and these fields are required to identify a namespace id since this
|
|
id can be released and later reused by a different namespace.
