NAME

6       cluster_selinux  -  Security Enhanced Linux Policy for the cluster pro‐
7       cesses
8

DESCRIPTION

10       Security-Enhanced Linux secures  the  cluster  processes  via  flexible
11       mandatory access control.
12
13       The  cluster processes execute with the cluster_t SELinux type. You can
14       check if you have these processes running by executing the  ps  command
15       with the -Z qualifier.
16
17       For example:
18
19       ps -eZ | grep cluster_t
20
21
22

ENTRYPOINTS

24       The  cluster_t  SELinux  type  can  be entered via the file_type, unla‐
25       beled_t, proc_type, filesystem_type, mtrr_device_t, sysctl_type,  clus‐
26       ter_exec_t file types.
27
28       The  default  entrypoint paths for the cluster_t domain are the follow‐
29       ing:
30
31       all files on the system, /dev/cpu/mtrr,  /usr/lib(64)?/heartbeat/heart‐
32       beat,    /usr/sbin/aisexec,   /usr/sbin/corosync,   /usr/sbin/cpglockd,
33       /usr/sbin/ccs_tool,      /usr/sbin/cman_tool,      /usr/sbin/rgmanager,
34       /usr/sbin/ldirectord, /usr/sbin/pacemakerd, /usr/sbin/corosync-notifyd,
35       /usr/sbin/pacemaker_remoted
36

PROCESS TYPES

38       SELinux defines process types (domains) for each process running on the
39       system
40
41       You can see the context of a process using the -Z option to ps
42
43       Policy  governs  the  access confined processes have to files.  SELinux
44       cluster policy is very flexible allowing users to setup  their  cluster
45       processes in as secure a method as possible.
46
47       The following process types are defined for cluster:
48
49       cluster_t
50
51       Note:  semanage permissive -a cluster_t can be used to make the process
52       type cluster_t permissive. SELinux does not deny access  to  permissive
53       process  types, but the AVC (SELinux denials) messages are still gener‐
54       ated.
55
56

BOOLEANS

58       SELinux policy is customizable based on least access required.  cluster
59       policy is extremely flexible and has several booleans that allow you to
60       manipulate the policy and run cluster with the tightest  access  possi‐
61       ble.
62
63
64
65       If  you  want to allow cluster administrative domains to connect to the
66       network using TCP, you must  turn  on  the  cluster_can_network_connect

241

PORT TYPES

243       SELinux defines port types to represent TCP and UDP ports.
244
245       You can see the types associated with a port  by  using  the  following
246       command:
247
248       semanage port -l
249
250
251       Policy  governs  the  access  confined  processes  have to these ports.
252       SELinux cluster policy is very flexible allowing users to  setup  their
253       cluster processes in as secure a method as possible.
254
255       The following port types are defined for cluster:
256
257
258       cluster_port_t
259
260
261
262       Default Defined Ports:
263                 tcp 5149,40040,50006-50008
264                 udp 5149,50006-50008
265

MANAGED FILES

267       The  SELinux  process  type cluster_t can manage files labeled with the
268       following file types.  The paths listed are the default paths for these
269       file types.  Note the processes UID still need to have DAC permissions.
270
271       file_type
272
273            all files on the system
274
275

FILE CONTEXTS

277       SELinux requires files to have an extended attribute to define the file
278       type.
279
280       You can see the context of a file using the -Z option to ls
281
282       Policy governs the access  confined  processes  have  to  these  files.
283       SELinux  cluster  policy is very flexible allowing users to setup their
284       cluster processes in as secure a method as possible.
285
286       STANDARD FILE CONTEXT
287
288       SELinux defines the file context types for the cluster, if  you  wanted
289       to store files with these types in a diffent paths, you need to execute
290       the semanage command  to  sepecify  alternate  labeling  and  then  use
291       restorecon to put the labels on disk.
292
293       semanage   fcontext   -a   -t   cluster_var_run_t  '/srv/mycluster_con‐
294       tent(/.*)?'
295       restorecon -R -v /srv/mycluster_content
296
297       Note: SELinux often uses regular expressions  to  specify  labels  that
298       match multiple files.
299
300       The following file types are defined for cluster:
301
302
303
304       cluster_conf_t
305
306       -  Set  files  with  the  cluster_conf_t type, if you want to treat the
307       files as cluster configuration data,  usually  stored  under  the  /etc
308       directory.
309
310
311
312       cluster_exec_t

345       cluster_tmpfs_t
346

348       files on a tmpfs file system.
349
350
351
352       cluster_var_lib_t
353
354       -  Set  files with the cluster_var_lib_t type, if you want to store the
355       cluster files under the /var/lib directory.

362            /var/lib/cluster(/.*)?
363
364
365       cluster_var_log_t
366
367       -  Set  files with the cluster_var_log_t type, if you want to treat the
368       data as cluster var log data, usually stored under the /var/log  direc‐
369       tory.
370
371
372       Paths:
373            /var/log/cluster/aisexec.log.*,   /var/log/cluster/cpglockd.log.*,

388
389
390       Note: File context can be temporarily modified with the chcon  command.
391       If  you want to permanently change the file context you need to use the
392       semanage fcontext command.  This will modify the SELinux labeling data‐
393       base.  You will need to use restorecon to apply the labels.
394
395

COMMANDS

397       semanage  fcontext  can also be used to manipulate default file context
398       mappings.
399
400       semanage permissive can also be used to manipulate  whether  or  not  a
401       process type is permissive.
402
403       semanage  module can also be used to enable/disable/install/remove pol‐
404       icy modules.
405
406       semanage port can also be used to manipulate the port definitions
407
408       semanage boolean can also be used to manipulate the booleans
409
410
411       system-config-selinux is a GUI tool available to customize SELinux pol‐
412       icy settings.
