NAME

6       ccs_selinux - Security Enhanced Linux Policy for the ccs processes
7

DESCRIPTION

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

ENTRYPOINTS

23       The ccs_t SELinux type can be entered via the ccs_exec_t file type.
24
25       The default entrypoint paths for the ccs_t domain are the following:
26
27       /sbin/ccsd
28

PROCESS TYPES

30       SELinux defines process types (domains) for each process running on the
31       system
32
33       You can see the context of a process using the -Z option to ps
34
35       Policy  governs  the  access confined processes have to files.  SELinux
36       ccs policy is very flexible allowing users to setup their ccs processes
37       in as secure a method as possible.
38
39       The following process types are defined for ccs:
40
41       ccs_t
42
43       Note: semanage permissive -a ccs_t can be used to make the process type
44       ccs_t permissive. SELinux does not deny access  to  permissive  process
45       types, but the AVC (SELinux denials) messages are still generated.
46
47

BOOLEANS

49       SELinux  policy  is  customizable  based on least access required.  ccs
50       policy is extremely flexible and has several booleans that allow you to
51       manipulate the policy and run ccs with the tightest access possible.

95
96
97
98       If you want to allow all domains to have the kernel load  modules,  you

MANAGED FILES

128       The  SELinux  process type ccs_t can manage files labeled with the fol‐
129       lowing file types.  The paths listed are the default  paths  for  these
130       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

214       SELinux requires files to have an extended attribute to define the file
215       type.
216
217       You can see the context of a file using the -Z option to ls
218
219       Policy governs the access  confined  processes  have  to  these  files.
220       SELinux  ccs  policy is very flexible allowing users to setup their ccs
221       processes in as secure a method as possible.
222
223       STANDARD FILE CONTEXT
224
225       SELinux defines the file context types for the ccs, if  you  wanted  to
226       store  files  with  these types in a diffent paths, you need to execute
227       the semanage command  to  sepecify  alternate  labeling  and  then  use
228       restorecon to put the labels on disk.
229
230       semanage fcontext -a -t ccs_var_run_t '/srv/myccs_content(/.*)?'
231       restorecon -R -v /srv/myccs_content
232
233       Note:  SELinux  often  uses  regular expressions to specify labels that
234       match multiple files.
235
236       The following file types are defined for ccs:
237
238
239
240       ccs_exec_t
241
242       - Set files with the ccs_exec_t type, if you want to transition an exe‐
243       cutable to the ccs_t domain.
244
245
246
247       ccs_tmp_t
248
249       - Set files with the ccs_tmp_t type, if you want to store ccs temporary
250       files in the /tmp directories.
251
252
253
254       ccs_tmpfs_t
255
256       - Set files with the ccs_tmpfs_t type, if you want to store  ccs  files
257       on a tmpfs file system.
258
259
260
261       ccs_var_lib_t
262
263       -  Set  files with the ccs_var_lib_t type, if you want to store the ccs
264       files under the /var/lib directory.
265
266
267
268       ccs_var_log_t
269
270       - Set files with the ccs_var_log_t type, if you want to treat the  data
271       as ccs var log data, usually stored under the /var/log directory.
272
273
274
275       ccs_var_run_t
276
277       -  Set  files with the ccs_var_run_t type, if you want to store the ccs
278       files under the /run or /var/run directory.
279
280
281       Paths:
282            /var/run/cluster/ccsd.pid, /var/run/cluster/ccsd.sock
283
284
285       Note: File context can be temporarily modified with the chcon  command.
286       If  you want to permanently change the file context you need to use the
287       semanage fcontext command.  This will modify the SELinux labeling data‐
288       base.  You will need to use restorecon to apply the labels.
289
290

COMMANDS

292       semanage  fcontext  can also be used to manipulate default file context
293       mappings.
294
295       semanage permissive can also be used to manipulate  whether  or  not  a
296       process type is permissive.
297
298       semanage  module can also be used to enable/disable/install/remove pol‐
299       icy modules.
300
301       semanage boolean can also be used to manipulate the booleans
302
303
304       system-config-selinux is a GUI tool available to customize SELinux pol‐
305       icy settings.
