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.
