The ipc_perm token contains a copy of the System V IPC access permissions. This token is added to audit records that are generated by IPC shared-memory events, IPC semaphore events, and IPC message events.
The ipc_perm token has eight fields:
A token ID that identifies this token as an ipc_perm token
The user ID of the IPC owner
The group ID of the IPC owner
The user ID of the IPC creator
The group ID of the IPC creator
The access mode of the IPC
The sequence number of the IPC
The IPC key value
The praudit -x command shows the fields of the ipc_perm token. The line is wrapped for display purposes.
<IPC_perm uid="jdoe" gid="staff" creator-uid="jdoe" creator-gid="staff" mode="100600" seq="0" key="0x0"/>
The values are taken from the ipc_perm structure that is associated with the IPC object.
