НАЗВАНИЕ

       avc_compute_create, avc_compute_member - obtain SELinux label for
       new object

СИНТАКСИС

       #include <selinux/selinux.h>
       #include <selinux/avc.h>

       int avc_compute_create(security_id_t ssid, security_id_t tsid,
                              security_class_t tclass, security_id_t
                              *newsid);

       int avc_compute_member(security_id_t ssid, security_id_t tsid,
                              security_class_t tclass, security_id_t
                              *newsid);

ОПИСАНИЕ

       avc_compute_create() is used to compute a SID to use for labeling
       a new object in a particular class based on a SID pair.  This
       call is identical to security_compute_create(), but does not
       require converting from userspace SID's to contexts and back
       again.

       avc_compute_member() is used to compute a SID to use for labeling
       a polyinstantiated object instance of a particular class based on
       a SID pair.  This call is identical to security_compute_member(),
       but does not require converting from userspace SID's to contexts
       and back again.

       These functions return a SID for the computed context in the
       memory referenced by sid.

ЗНАЧЕНИЕ ВОЗВРАЩАЕМОГО ЗНАЧЕНИЯ

       On success, zero is returned.  On error, -1 is returned and errno
       is set appropriately.

ОШИБКИ

       EINVAL The tclass and/or the security contexts referenced by ssid
              and tsid are not recognized by the currently loaded
              policy.

       ENOMEM An attempt to allocate memory failed.
