The attr token contains information from the file vnode. This token has 7 fields: a token ID that identifies this as an attr token, the file access mode and type, the owner user ID, the owner group ID, the file system ID, the inode ID, and device ID the file might represent. See the statvfs(2) man page for further information about the file system ID and the device ID. This token usually accompanies a path token and is produced during path searches. In the event of a path-search error, this token is not included as part of the audit record since there is no vnode available to obtain the necessary file information. Figure A-4 shows the attr token format.
