insmod_selinux(8) insmod SELinux Policy documentation insmod_selinux(8)NAMEinsmod_selinux - Security Enhanced Linux Policy for the insmod pro‐
cesses
DESCRIPTION
Security-Enhanced Linux secures the insmod processes via flexible
mandatory access control.
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 disallow programs and users from transitioning to insmod
domain, 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
NSSWITCH DOMAIN
If you want to allow users to login using a sssd serve for the ins‐
mod_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
insmod_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 insmod_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 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.*, /usr/sbin/mod‐
probe.*, /usr/bin/kmod, /usr/sbin/insmod.*, /usr/sbin/rmmod.*
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 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
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 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.
