ipc_perm Token

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.
