load_selinux(8) load SELinux Policy documentation load_selinux(8)NAMEload_selinux - Security Enhanced Linux Policy for the load processes
DESCRIPTION
Security-Enhanced Linux secures the load processes via flexible manda‐
tory access control.
BOOLEANS
SELinux policy is customizable based on least access required. load
policy is extremely flexible and has several booleans that allow you to
manipulate the policy and run load with the tightest access possible.
If you want to prevent all confined domains from loading policy, set‐
ting enforcing mode, and changing boolean values. Set this to true and
you have to reboot to set it bac, you must turn on the secure_mode_pol‐
icyload boolean.
setsebool -P secure_mode_policyload 1
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
If you want to allow all domains to have the kernel load module, you
must turn on the domain_kernel_load_modules boolean.
setsebool -P domain_kernel_load_modules 1
NSSWITCH DOMAINFILE 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 load policy is very flexible allowing users to setup their load
processes in as secure a method as possible.
The following file types are defined for load:
load_policy_exec_t
- Set files with the load_policy_exec_t type, if you want to transition
an executable to the load_policy_t domain.
Paths:
/usr/sbin/load_policy, /sbin/load_policy
loadkeys_exec_t
- Set files with the loadkeys_exec_t type, if you want to transition an
executable to the loadkeys_t domain.
Paths:
/bin/unikeys, /bin/loadkeys, /usr/bin/unikeys, /usr/bin/loadkeys
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
load policy is very flexible allowing users to setup their load pro‐
cesses in as secure a method as possible.
The following process types are defined for load:
loadkeys_t, load_policy_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.
