Data Types for X11

The following data types are defined in X11/extensions/Xtsol.h and are used for the Trusted Extensions X Window System APIs:

• Object type for X11 – The ResourceType definition indicates the type of resource to be handled. The value can be IsWindow, IsPixmap, or IsColormap.

  ResourceType is a type definition to represent a clearance. Interfaces accept a structure of type m_label_t as parameters and return clearances in a structure of the same type.

• Object attributes for X11 –The XTsolResAttributes structure contains these resource attributes:

  typedef struct _XTsolResAttributes {
  CARD32     ouid;    /* owner uid */
  CARD32     uid;     /* uid of the window */
  m_label_t  *sl;     /* sensitivity label */
  } XTsolResAttributes;

• Property attributes for X11 – The XTsolPropAttributes structure contains these property attributes:

  typedef struct _XTsolPropAttributes {
  CARD32     uid;     /* uid of the property */
  m_label_t  *sl;     /* sensitivity label */
  } XTsolPropAttributes;

• Client attributes for X11 – The XTsolClientAttributes structure contains these client attributes:

  typedef struct _XTsolClientAttributes {
  int      trustflag; /* true if client masked as trusted */
  uid_t    uid;       /* owner uid who started the client */
  gid_t    gid;       /* group id */
  pid_t    pid;       /* process id */
  u_long   sessionid; /* session id */
  au_id_t  auditid;   /* audit id */
  u_long   iaddr;     /* internet addr of host where client is running */
  } XTsolClientAttributes;
