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.
