NAME

       selabel_db  - userspace SELinux labeling interface: DB objects contexts
       backend.

SYNOPSIS

       #include <selinux/selinux.h>

       #include <selinux/label.h>

       int selabel_lookup(struct selabel_handle *hnd,
                          security_context_t *context,

                          const char *object_name, int object_type);

DESCRIPTION

       The DB contexts backend maps from a pair of object name and class  into
       security  contexts.  It  is  used  to  find the appropriate context for
       database objects when relabeling a certain database.

       The object_name should be fully qualified name using the  hierarchy  of
       database  objects.   For  example,  the  pg_class table in the postgres
       database   and   pg_catalog   schema    should    be    qualified    as
       postgres.pg_catalog.pg_class .

       The object_type argument should be set to one of the following values:

       SELABEL_DB_DATABASE
              The  object_name  argument  specifies  the  name  of  a database
              itself, such as "postgres".

       SELABEL_DB_SCHEMA
              The object_name argument specifies the name of a schema  object,
              such as "postgres.public".

       SELABEL_DB_TABLE
              The  object_name  argument specifies the name of a table object,
              such as "postgres.public.my_table"

       SELABEL_DB_COLUMN
              The object_name argument specifies the name of a column  object,
              such as "postgres.public.my_table.user_id"

       SELABEL_DB_TUPLE
              The  object_name  argument  specifies the name of a table object
              which  contains  the   tuples   to   be   relabeled,   such   as
              "postgresql.public.my_table".  Note  that  we  have  no  way  to
              identify individual tuple objects, except for  WHERE  clause  on
              DML statements, because it has no name.

       SELABEL_DB_PROCEDURE
              The  object_name  argument  specifies  the  name  of a procedure
              object, such as "postgres.public.my_func". Note  that  we  don't
              support   to   lookup  individual  security  contexts  for  each
              procedures which have same name but different arguments.

       SELABEL_DB_SEQUENCE
              The object_name  argument  specifies  the  name  of  a  sequence
              object, such as "postgres.public.my_seq".

       SELABEL_DB_BLOB
              The  object_name  argument specifies the name of a large object,
              such as "postgres.16308".  Note that a  large  object  does  not
              have its name, so it is identified by its identifier value.

OPTIONS

       In  addition  to  the global options described in selabel_open(3), this
       backend recognizes the following options:

       SELABEL_OPT_PATH
              A non-null value for this option specifies a path to a file that
              will  be  opened  in  lieu of the standard DB contexts file.  It
              tries to open the specfile designed  for  SE-PostgreSQL  in  the
              default,  so  if  another RDBMS uses this interface, it needs to
              give an explicit specfile designed for the RDBMS.
