semanage_selinux(8) semanage SELinux Policy documentation semanage_selinux(8)NAMEsemanage_selinux - Security Enhanced Linux Policy for the semanage pro‐
cesses
DESCRIPTION
Security-Enhanced Linux secures the semanage processes via flexible
mandatory access control.
NSSWITCH DOMAIN
If you want to allow users to login using a sssd serve for the seman‐
age_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
semanage_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 semanage_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 semanage policy is very flexible allowing users to setup their
semanage processes in as secure a method as possible.
The following file types are defined for semanage:
semanage_exec_t
- Set files with the semanage_exec_t type, if you want to transition an
executable to the semanage_t domain.
Paths:
/usr/share/system-config-selinux/system-config-selinux-dbus.py,
/usr/sbin/semanage, /usr/sbin/semodule
semanage_read_lock_t
- Set files with the semanage_read_lock_t type, if you want to treat
the files as semanage read lock data, stored under the /var/lock direc‐
tory
semanage_store_t
- Set files with the semanage_store_t type, if you want to treat the
files as semanage store data.
Paths:
/etc/share/selinux/mls(/.*)?, /etc/selinux/([^/]*/)?mod‐
ules/(active|tmp|previous)(/.*)?, /etc/selinux/([^/]*/)?pol‐
icy(/.*)?, /etc/share/selinux/targeted(/.*)?
semanage_tmp_t
- Set files with the semanage_tmp_t type, if you want to store semanage
temporary files in the /tmp directories.
semanage_trans_lock_t
- Set files with the semanage_trans_lock_t type, if you want to treat
the files as semanage trans lock data, stored under the /var/lock
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
semanage policy is very flexible allowing users to setup their semanage
processes in as secure a method as possible.
The following process types are defined for semanage:
semanage_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.
system-config-selinux is a GUI tool available to customize SELinux pol‐
icy settings.
