NAME

6       ctdbd_selinux - Security Enhanced Linux Policy for the ctdbd processes
7

DESCRIPTION

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

ENTRYPOINTS

23       The ctdbd_t SELinux type can be entered via the ctdbd_exec_t file type.
24
25       The default entrypoint paths for the ctdbd_t domain are the following:
26
27       /etc/ctdb/events.d/.*, /usr/sbin/ctdbd, /usr/sbin/ctdbd_wrapper
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       ctdbd policy is very flexible allowing users to setup their ctdbd  pro‐
37       cesses in as secure a method as possible.
38
39       The following process types are defined for ctdbd:
40
41       ctdbd_t
42
43       Note:  semanage  permissive  -a ctdbd_t can be used to make the process
44       type ctdbd_t permissive. SELinux does not  deny  access  to  permissive
45       process  types, but the AVC (SELinux denials) messages are still gener‐
46       ated.
47
48

BOOLEANS

50       SELinux policy is customizable based on least access  required.   ctdbd
51       policy is extremely flexible and has several booleans that allow you to
52       manipulate the policy and run ctdbd with the tightest access possible.
53
54
55
56       If you want to dontaudit all  daemons  scheduling  requests  (setsched,
57       sys_nice),  you  must turn on the daemons_dontaudit_scheduling boolean.
58       Enabled by default.
59
60       setsebool -P daemons_dontaudit_scheduling 1
61
62
63
64       If you want to allow all domains to execute in fips_mode, you must turn
65       on the fips_mode boolean. Enabled by default.
66
67       setsebool -P fips_mode 1
68
69
70
71       If  you  want  to  allow  system  to run with NIS, you must turn on the
72       nis_enabled boolean. Disabled by default.
73
74       setsebool -P nis_enabled 1
75
76
77

PORT TYPES

79       SELinux defines port types to represent TCP and UDP ports.
80
81       You can see the types associated with a port  by  using  the  following
82       command:
83
84       semanage port -l
85
86
87       Policy  governs  the  access  confined  processes  have to these ports.
88       SELinux ctdbd policy is very flexible allowing users to setup their ct‐
89       dbd processes in as secure a method as possible.
90
91       The following port types are defined for ctdbd:
92
93
94       ctdb_port_t
95
96
97
98       Default Defined Ports:
99                 tcp 4379
100                 udp 4379
101

MANAGED FILES

103       The SELinux process type ctdbd_t can manage files labeled with the fol‐
104       lowing file types.  The paths listed are the default  paths  for  these
105       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

206       SELinux requires files to have an extended attribute to define the file
207       type.
208
209       You can see the context of a file using the -Z option to ls
210
211       Policy governs the access  confined  processes  have  to  these  files.
212       SELinux ctdbd policy is very flexible allowing users to setup their ct‐
213       dbd processes in as secure a method as possible.
214
215       EQUIVALENCE DIRECTORIES
216
217
218       ctdbd policy stores data with multiple different file context types un‐
219       der  the  /var/lib/ctdb directory.  If you would like to store the data
220       in a different directory you can use the semanage command to create  an
221       equivalence  mapping.   If you wanted to store this data under the /srv
222       directory you would execute the following command:
223
224       semanage fcontext -a -e /var/lib/ctdb /srv/ctdb
225       restorecon -R -v /srv/ctdb
226
227       ctdbd policy stores data with multiple different file context types un‐
228       der  the  /var/run/ctdb directory.  If you would like to store the data
229       in a different directory you can use the semanage command to create  an
230       equivalence  mapping.   If you wanted to store this data under the /srv
231       directory you would execute the following command:
232
233       semanage fcontext -a -e /var/run/ctdb /srv/ctdb
234       restorecon -R -v /srv/ctdb
235
236       STANDARD FILE CONTEXT
237
238       SELinux defines the file context types for the ctdbd, if you wanted  to
239       store  files with these types in a different paths, you need to execute
240       the semanage command to specify alternate labeling  and  then  use  re‐
241       storecon to put the labels on disk.
242
243       semanage fcontext -a -t ctdbd_exec_t '/srv/ctdbd/content(/.*)?'
244       restorecon -R -v /srv/myctdbd_content
245
246       Note:  SELinux  often  uses  regular expressions to specify labels that
247       match multiple files.
248
249       The following file types are defined for ctdbd:
250
251
252
253       ctdbd_exec_t
254
255       - Set files with the ctdbd_exec_t type, if you want  to  transition  an
256       executable to the ctdbd_t domain.
257
258
259       Paths:
260            /etc/ctdb/events.d/.*, /usr/sbin/ctdbd, /usr/sbin/ctdbd_wrapper
261
262
263       ctdbd_initrc_exec_t
264
265       -  Set  files with the ctdbd_initrc_exec_t type, if you want to transi‐
266       tion an executable to the ctdbd_initrc_t domain.
267
268
269
270       ctdbd_log_t
271
272       - Set files with the ctdbd_log_t type, if you want to treat the data as
273       ctdbd log data, usually stored under the /var/log directory.
274
275
276       Paths:
277            /var/log/ctdb.log.*, /var/log/log.ctdb.*
278
279
280       ctdbd_spool_t
281
282       - Set files with the ctdbd_spool_t type, if you want to store the ctdbd
283       files under the /var/spool directory.
284
285
286
287       ctdbd_tmp_t
288
289       - Set files with the ctdbd_tmp_t type, if you want to store ctdbd  tem‐
290       porary files in the /tmp directories.
291
292
293
294       ctdbd_var_lib_t
295
296       - Set files with the ctdbd_var_lib_t type, if you want to store the ct‐
297       dbd files under the /var/lib directory.
298
299
300       Paths:
301            /var/lib/ctdb(/.*)?, /var/lib/ctdbd(/.*)?
302
303
304       ctdbd_var_run_t
305
306       - Set files with the ctdbd_var_run_t type, if you want to store the ct‐
307       dbd files under the /run or /var/run directory.
308
309
310       Paths:
311            /var/run/ctdb(/.*)?, /var/run/ctdbd(/.*)?
312
313
314       ctdbd_var_t
315
316       - Set files with the ctdbd_var_t type, if you want to store the c files
317       under the /var directory.
318
319
320
321       Note: File context can be temporarily modified with the chcon  command.
322       If  you want to permanently change the file context you need to use the
323       semanage fcontext command.  This will modify the SELinux labeling data‐
324       base.  You will need to use restorecon to apply the labels.
325
326

COMMANDS

328       semanage  fcontext  can also be used to manipulate default file context
329       mappings.
330
331       semanage permissive can also be used to manipulate  whether  or  not  a
332       process type is permissive.
333
334       semanage  module can also be used to enable/disable/install/remove pol‐
335       icy modules.
336
337       semanage port can also be used to manipulate the port definitions
338
339       semanage boolean can also be used to manipulate the booleans
340
341
342       system-config-selinux is a GUI tool available to customize SELinux pol‐
343       icy settings.
