cat command to inspect the contents of the TE file:
module mysemanage 1.0;
class fd use;
allow semanage_t init_t:fd use;
The TE file is comprised of three sections. The first section is the
module command, which identifies the module name and version. The module name must be unique. If you create an
semanage module using the name of a pre-existing module, the system would try to replace the existing module package with the newly-created version. The last part of the module line is the version.
semodule can update module packages and checks the update version against the currently installed version.
The next block of the TE file is the
require block. This informs the policy loader which types, classes and roles are required in the system policy before this module can be installed. If any of these fields are undefined, the
semodule command will fail.
Lastly are the allow rules. In this example, you could modify this line to
semodule does not need to access the file descriptor.
