NAME firstboot_selinux - Security Enhanced Linux Policy for the firstboot processes

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

The firstboot processes execute with the firstboot_t SELinux type. You can check if you have these processes running by executing the ps com- mand with the -Z qualifier.

For example:

ps -eZ | grep firstboot_t

ENTRYPOINTS The firstboot_t SELinux type can be entered via the "mtrr_device_t,firstboot_exec_t,unla- beled_t,proc_type,sysctl_type,filesystem_type,file_type" file types. The default entrypoint paths for the firstboot_t domain are the follow- ing:"

/dev/cpu/mtrr, /usr/sbin/firstboot, /usr/share/firstboot/firstboot.py, all files on the system

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 firstboot policy is very flexible allowing users to setup their first- boot processes in as secure a method as possible.

The following process types are defined for firstboot:

firstboot_t

Note: semanage permissive -a firstboot_t

can be used to make the process type firstboot_t permissive. Permissive process types are not denied access by SELinux. AVC messages will still be generated.

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 firstboot policy is very flexible allowing users to setup their firstboot processes in as secure a method as possible.

The following file types are defined for firstboot:

firstboot_etc_t

- Set files with the firstboot_etc_t type, if you want to store first- boot files in the /etc directories.

firstboot_exec_t

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

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

MANAGED FILES The SELinux process type firstboot_t can manage files labeled with the following file types. The paths listed are the default paths for these file types. Note the processes UID still need to have DAC permissions.

file_type

all files on the system

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.

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