avc_compute_create(3) SELinux API documentation avc_compute_create(3)
avc_compute_create, avc_compute_member - obtain SELinux label for new
object
#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);
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.
On success, zero is returned. On error, -1 is returned and errno is
set appropriately.
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.
