.SH "DESCRIPTION"
|
|
.B 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
|
|
.BR security_compute_create ,
|
|
but does not require converting from userspace SID's to contexts and back again.
|
|
|
|
.B 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
|
|
.BR 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
|
|
.IR sid .
|
|
|
|
.SH "RETURN VALUE"
|
|
On success, zero is returned. On error, \-1 is returned and
|
|
.I errno
|
|
is set appropriately.
|
|
|
|
.SH "ERRORS"
|
|
.TP
|
|
.B EINVAL
|
|
The
|
|
.I tclass
|
|
and/or the security contexts referenced by
|
|
.I ssid
|
|
and
|
|
.I tsid
|
|
are not recognized by the currently loaded policy.
|
|
|
|
.TP
|
|
.B ENOMEM
|
|
An attempt to allocate memory failed.
