NAME

       avc_compute_create, avc_compute_member - obtain SELinux label for new object

SYNOPSIS

       #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);

DESCRIPTION

       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.

RETURN VALUE

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

ERRORS

       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.
