NAME

insmod_selinux - Security Enhanced Linux Policy for the insmod processes  

DESCRIPTION

 

BOOLEANS

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

If you want to disable transitions to insmod, you must turn on the secure_mode_insmod boolean.

setsebool -P secure_mode_insmod 1

If you want to allow pppd to load kernel modules for certain modem, you must turn on the pppd_can_insmod boolean.

setsebool -P pppd_can_insmod 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 lsP Policy governs the access confined processes have to these files. SELinux insmod policy is very flexible allowing users to setup their insmod processes in as secure a method as possible.

The following file types are defined for insmod:

insmod_exec_t

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


Paths:
/sbin/modprobe.*, /sbin/rmmod.*, /sbin/insmod.*

insmod_tmpfs_t

- Set files with the insmod_tmpfs_t type, if you want to store insmod files on a tmpfs file system.

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.

 

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

The following process types are defined for insmod:

insmod_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 policy modules.

semanage boolean can also be used to manipulate the booleans

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