NAME
       bootloader_selinux  - Security Enhanced Linux Policy for the bootloader
       processes

DESCRIPTION
       Security-Enhanced Linux secures the bootloader processes	 via  flexible
       mandatory access control.

BOOLEANS
       SELinux	policy	is customizable based on least access required.	 boot‐
       loader policy is extremely flexible and has several booleans that allow
       you  to	manipulate  the	 policy	 and  run bootloader with the tightest
       access possible.

       If you want to allow the graphical login program to execute  bootloade,
       you must turn on the xdm_exec_bootloader boolean.

       setsebool -P xdm_exec_bootloader 1

NSSWITCH DOMAIN
       If  you	want  to allow users to login using a sssd serve for the boot‐
       loader_t, you must turn on the authlogin_nsswitch_use_ldap boolean.

       setsebool -P authlogin_nsswitch_use_ldap 1

       If you want to allow confined applications to run with kerberos for the
       bootloader_t, you must turn on the allow_kerberos boolean.

       setsebool -P allow_kerberos 1

       If  you	want  to allow system to run with NI for the bootloader_t, you
       must turn on the allow_ypbind boolean.

       setsebool -P allow_ypbind 1

FILE CONTEXTS
       SELinux requires files to have an extended attribute to define the file
       type.

       You can see the context of a file using the -Z option to ls

       Policy  governs	the  access  confined  processes  have to these files.
       SELinux bootloader policy is very  flexible  allowing  users  to	 setup
       their bootloader processes in as secure a method as possible.

       The following file types are defined for bootloader:

       bootloader_etc_t

       -  Set files with the bootloader_etc_t type, if you want to store boot‐
       loader files in the /etc directories.

       Paths:
	    /etc/zipl.conf.*,	   /etc/yaboot.conf.*,	    /etc/default/grub,
	    /etc/lilo.conf.*

       bootloader_exec_t

       -  Set files with the bootloader_exec_t type, if you want to transition
       an executable to the bootloader_t domain.

       Paths:
	    /usr/sbin/ybin.*, /usr/sbin/grub.*, /usr/sbin/zipl,	 /sbin/lilo.*,
	    /sbin/ybin.*, /usr/sbin/lilo.*, /sbin/grub.*, /sbin/zipl

       bootloader_tmp_t

       -  Set files with the bootloader_tmp_t type, if you want to store boot‐
       loader temporary files in the /tmp directories.

       bootloader_var_run_t

       - Set files with the bootloader_var_run_t type, if you  want  to	 store
       the bootloader files under the /run directory.

       Note:  File context can be temporarily modified with the chcon command.
       If you want to permanantly change the file context you need to use  the
       semanage fcontext command.  This will modify the SELinux labeling data‐
       base.  You will need to use restorecon to apply the labels.

PROCESS TYPES
       SELinux defines process types (domains) for each process running on the
       system

       You can see the context of a process using the -Z option to ps

       Policy  governs	the  access confined processes have to files.  SELinux
       bootloader policy is very flexible allowing users to setup their	 boot‐
       loader processes in as secure a method as possible.

       The following process types are defined for bootloader:

       bootloader_t

       Note: semanage permissive -a PROCESS_TYPE can be used to make a process
       type permissive. Permissive process types  are  not  denied  access  by
       SELinux. AVC messages will still be generated.

COMMANDS
       semanage	 fcontext  can also be used to manipulate default file context
       mappings.

       semanage permissive can also be used to manipulate  whether  or	not  a
       process type is permissive.

       semanage	 module can also be used to enable/disable/install/remove pol‐
       icy modules.

       semanage boolean can also be used to manipulate the booleans

       system-config-selinux is a GUI tool available to customize SELinux pol‐
       icy settings.
