+ * access to the policy xp.
+ * @dir contains the direction of the flow (input or output).
+ * Check permission when a sock selects a xfrm_policy for processing

* Security hooks affecting all Key Management operations
*
* @ipcp contains the kernel IPC permission structure
* @flag contains the desired (requested) permission set
* Return 0 if permission is granted.
+ * @ipc_getsecurity:
+ * Copy the security label associated with the ipc object into
+ * @buffer. @buffer may be NULL to request the size of the buffer
+ * required. @size indicates the size of @buffer in bytes. Return
+ * number of bytes used/required on success.
*
* Security hooks for individual messages held in System V IPC message queues
* @msg_msg_alloc_security:
* @effective contains the effective capability set.
* @inheritable contains the inheritable capability set.

* @acct:
* Check permission before enabling or disabling process accounting. If
* accounting is being enabled, then @file refers to the open file used to
* @table contains the ctl_table structure for the sysctl variable.
* @op contains the operation (001 = search, 002 = write, 004 = read).

- * @capable:
- * Check whether the @tsk process has the @cap capability.
- * @tsk contains the task_struct for the process.
