DESCRIPTION

Use sepolicy generate to generate an SELinux policy Module.

sepolicy generate will create 5 files.

When specifying a confined application you must specify a path. sepolicy generate will use the rpm payload of the application along with nm -D APPLICATION to help it generate types and policy rules for your policy files.

Type Enforcing File NAME.te
This file can be used to define all the types rules for a particular domain.

Note: Policy generated by sepolicy generate will automatically add a permissive DOMAIN to your te file. When you are satisfied that your policy works, you need to remove the permissive line from the te file to run your domain in enforcing mode.

Interface File NAME.if
This file defines the interfaces for the types generated in the te file, which can be used by other policy domains.

File Context NAME.fc
This file defines the default file context for the system, it takes the file types created in the te file and associates file paths to the types. Tools like restorecon and RPM will use these paths to put down labels.

RPM Spec File NAME_selinux.spec
This file is an RPM SPEC file that can be used to install the SELinux policy on to machines and setup the labeling. The spec file also installs the interface file and a man page describing the policy. You can use sepolicy manpage -d NAME to generate the man page.

Shell File NAME.sh
This is a helper shell script to compile, install and fix the labeling on your test system. It will also generate a man page based on the installed policy, and compile and build an RPM suitable to be installed on other machines

If a generate is possible, this tool will print out all generate paths from the source domain to the target domain

OPTIONS

-h, --help

Display help message

-d, --domain

Enter domain type(s) which you will be extending

-n, --name

-p, --path

Specify the directory to store the created policy files. (Default to current working directory ) optional arguments:

-r, --role

Enter role(s) to which this admin user will transition.

-t, --type

Enter type(s) for which you will generate new definition and rule(s)

-u, --user

SELinux user(s) which will transition to this domain

-w, --writepath

Path(s) which the confined processes need to write

-a, --admin

Domain(s) which the confined admin will administrate

--admin_user

Generate Policy for Administrator Login User Role

--application

Generate Policy for User Application

--cgi

Generate Policy for Web Application/Script (CGI)

--confined_admin

Generate Policy for Confined Root Administrator Role

--customize

Generate Policy for Existing Domain Type

--dbus

Generate Policy for DBUS System Daemon

--desktop_user

Generate Policy for Desktop Login User Role

--inetd

Generate Policy for Internet Services Daemon

--init

Generate Policy for Standard Init Daemon (Default)

--newtype

Generate new policy for new types to add to an existing policy.

--sandbox

Generate Policy for Sandbox

--term_user

Generate Policy for Minimal Terminal Login User Role

--x_user

Generate Policy for Minimal X Windows Login User Role

EXAMPLE

> sepolicy generate --init /usr/sbin/rwhod
Generating Policy for /usr/sbin/rwhod named rwhod
Created the following files:
rwhod.te # Type Enforcement file
rwhod.if # Interface file
rwhod.fc # File Contexts file
rwhod_selinux.spec # Spec file
rwhod.sh # Setup Script
