.SH "NAME"
|
|
sepol_genusers \- Generate a new binary policy image with a customized user configuration
|
|
.SH "SYNOPSIS"
|
|
.B #include <sepol/sepol.h>
|
|
.sp
|
|
.BI "int sepol_genusers(void *" data ", size_t "len ", const char *" usersdir ", void *" newdata ", size_t *" newlen);

|
|
|
|
.SH "DESCRIPTION"
|
|
.B sepol_genusers
|
|
generates a new binary policy image from
|
|
an existing binary policy image stored in the memory region described by
|
|
the starting address
|
|
.I data
|
|
and the length
|
|
.I len
|
|
and a pair of user configuration files named
|
|
.B system.users
|
|
and
|
|
.B local.users
|
|
from the directory specified by
|
|
.I usersdir.
|
|
The resulting binary policy is placed into dynamically allocated
|
|
memory and the variables
|
|
.I newdata
|
|
and
|
|
.I newlen
|
|
are set to refer to the new binary image's starting address and length.
|
|
The original binary policy image is not modified.
|
|
|
|
By default,
|
|
.B sepol_genusers
|
|
will preserve user entries that are defined in the original binary policy image
|
|
but not defined in the user configuration files. If such user entries
|
|
should instead by omitted entirely from the new binary policy image, then
|
|
the
|
|
.B sepol_set_delusers
|
|
function may be called with
|
|
.I on
|
|
set to 1 prior to calling
|
|
.B sepol_genusers
|
|
in order to enable deletion of such users.
|
|
|
|
.SH "RETURN VALUE"
|
|
Returns 0 on success or \-1 otherwise, with errno set appropriately.
|
|
An errno of ENOENT indicates that one or both of the user
|
|
configuration files did not exist. An errno of EINVAL indicates that
|
|
either the original binary policy image or the generated one were
|
|
invalid. An errno of ENOMEM indicates that insufficient memory was
|
|
available to process the original binary policy image or to generate
|
|
the new policy image. Invalid entries in the user configuration files
|
|
are skipped with a warning.
