sanlock_selinux(8) sanlock SELinux Policy documentation sanlock_selinux(8)NAMEsanlock_selinux - Security Enhanced Linux Policy for the sanlock pro‐
cesses
DESCRIPTION
Security-Enhanced Linux secures the sanlock processes via flexible
mandatory access control.
BOOLEANS
SELinux policy is customizable based on least access required. sanlock
policy is extremely flexible and has several booleans that allow you to
manipulate the policy and run sanlock with the tightest access possi‐
ble.
If you want to allow confined virtual guests to interact with the san‐
loc, you must turn on the virt_use_sanlock boolean.
setsebool -P virt_use_sanlock 1
If you want to allow sanlock to manage nfs file, you must turn on the
sanlock_use_nfs boolean.
setsebool -P sanlock_use_nfs 1
If you want to allow sanlock to manage cifs file, you must turn on the
sanlock_use_samba boolean.
setsebool -P sanlock_use_samba 1
NSSWITCH DOMAIN
If you want to allow users to login using a sssd serve for the san‐
lock_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
sanlock_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 sanlock_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 sanlock policy is very flexible allowing users to setup their
sanlock processes in as secure a method as possible.
The following file types are defined for sanlock:
sanlock_exec_t
- Set files with the sanlock_exec_t type, if you want to transition an
executable to the sanlock_t domain.
sanlock_initrc_exec_t
- Set files with the sanlock_initrc_exec_t type, if you want to transi‐
tion an executable to the sanlock_initrc_t domain.
sanlock_log_t
- Set files with the sanlock_log_t type, if you want to treat the data
as sanlock log data, usually stored under the /var/log directory.
sanlock_var_run_t
- Set files with the sanlock_var_run_t type, if you want to store the
sanlock files under the /run 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
sanlock policy is very flexible allowing users to setup their sanlock
processes in as secure a method as possible.
The following process types are defined for sanlock:
sanlock_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.
