NAME fenced_selinux - Security Enhanced Linux Policy for the fenced pro- cesses

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

If you want to allow fenced domain to connect to the network using TCP, you must turn on the fenced_can_network_connect boolean.

setsebool -P fenced_can_network_connect 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 fenced policy is very flexible allowing users to setup their fenced processes in as secure a method as possible.

The following file types are defined for fenced:

fenced_exec_t

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

Paths: /sbin/fence_node, /sbin/fence_tool, /sbin/fenced

fenced_lock_t

- Set files with the fenced_lock_t type, if you want to treat the files as fenced lock data, stored under the /var/lock directory

fenced_tmp_t

- Set files with the fenced_tmp_t type, if you want to store fenced temporary files in the /tmp directories.

fenced_tmpfs_t

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

fenced_var_log_t

- Set files with the fenced_var_log_t type, if you want to treat the data as fenced var log data, usually stored under the /var/log direc- tory.

fenced_var_run_t

- Set files with the fenced_var_run_t type, if you want to store the fenced files under the /run directory.

Paths: /var/run/cluster/fenced_override, /var/run/fenced.pid

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 ps

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

The following process types are defined for fenced:

fenced_t

COMMANDS semanage fcontext can also be used to manipulate default file context mappings.

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.
