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.
