avc_compute_member: obtain SELinux label for new object
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.
