NAME

6       keystone_selinux - Security Enhanced Linux Policy for the keystone pro‐
7       cesses
8

DESCRIPTION

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

ENTRYPOINTS

24       The keystone_t SELinux type can be entered via the keystone_exec_t file
25       type.
26
27       The default entrypoint paths for the keystone_t domain are the  follow‐
28       ing:
29
30       /usr/bin/keystone-all
31

PROCESS TYPES

33       SELinux defines process types (domains) for each process running on the
34       system
35
36       You can see the context of a process using the -Z option to ps
37
38       Policy governs the access confined processes have  to  files.   SELinux
39       keystone policy is very flexible allowing users to setup their keystone
40       processes in as secure a method as possible.
41
42       The following process types are defined for keystone:
43
44       keystone_t, keystone_cgi_script_t
45
46       Note: semanage permissive -a keystone_t can be used to make the process
47       type  keystone_t permissive. SELinux does not deny access to permissive
48       process types, but the AVC (SELinux denials) messages are still  gener‐
49       ated.
50
51

BOOLEANS

53       SELinux  policy  is  customizable based on least access required.  key‐
54       stone policy is extremely flexible and has several booleans that  allow
55       you  to manipulate the policy and run keystone with the tightest access
56       possible.

PORT TYPES

171       SELinux defines port types to represent TCP and UDP ports.
172
173       You can see the types associated with a port  by  using  the  following
174       command:
175
176       semanage port -l
177
178
179       Policy  governs  the  access  confined  processes  have to these ports.
180       SELinux keystone policy is very flexible allowing users to setup  their
181       keystone processes in as secure a method as possible.
182
183       The following port types are defined for keystone:
184
185
186       keystone_port_t
187
188
189
190       Default Defined Ports:
191                 tcp 35357
192                 udp 35357
193

MANAGED FILES

195       The  SELinux  process type keystone_t can manage files labeled with the
196       following file types.  The paths listed are the default paths for these
197       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

275       SELinux requires files to have an extended attribute to define the file
276       type.
277
278       You can see the context of a file using the -Z option to ls
279
280       Policy governs the access  confined  processes  have  to  these  files.
281       SELinux  keystone policy is very flexible allowing users to setup their
282       keystone processes in as secure a method as possible.
283
284       STANDARD FILE CONTEXT
285
286       SELinux defines the file context types for the keystone, if you  wanted
287       to store files with these types in a diffent paths, you need to execute
288       the semanage command  to  sepecify  alternate  labeling  and  then  use
289       restorecon to put the labels on disk.
290
291       semanage   fcontext   -a  -t  keystone_var_run_t  '/srv/mykeystone_con‐
292       tent(/.*)?'
293       restorecon -R -v /srv/mykeystone_content
294
295       Note: SELinux often uses regular expressions  to  specify  labels  that
296       match multiple files.
297
298       The following file types are defined for keystone:
299
300
301
302       keystone_cgi_content_t
303
304       -  Set files with the keystone_cgi_content_t type, if you want to treat
305       the files as keystone cgi content.
306
307
308
309       keystone_cgi_htaccess_t
310
311       - Set files with the keystone_cgi_htaccess_t type, if you want to treat
312       the file as a keystone cgi access file.
313
314
315
316       keystone_cgi_ra_content_t
317
318       -  Set  files  with  the keystone_cgi_ra_content_t type, if you want to
319       treat the files as keystone cgi  read/append content.
320
321
322
323       keystone_cgi_rw_content_t
324
325       - Set files with the keystone_cgi_rw_content_t type,  if  you  want  to
326       treat the files as keystone cgi read/write content.
327
328
329
330       keystone_cgi_script_exec_t
331
332       -  Set  files  with the keystone_cgi_script_exec_t type, if you want to
333       transition an executable to the keystone_cgi_script_t domain.
334
335
336
337       keystone_exec_t
338
339       - Set files with the keystone_exec_t type, if you want to transition an
340       executable to the keystone_t domain.
341
342
343
344       keystone_initrc_exec_t
345
346       -  Set files with the keystone_initrc_exec_t type, if you want to tran‐
347       sition an executable to the keystone_initrc_t domain.
348
349
350
351       keystone_log_t
352
353       - Set files with the keystone_log_t type, if you want to treat the data
354       as keystone log data, usually stored under the /var/log directory.
355
356
357
358       keystone_tmp_t
359
360       - Set files with the keystone_tmp_t type, if you want to store keystone
361       temporary files in the /tmp directories.
362
363
364
365       keystone_unit_file_t
366
367       - Set files with the keystone_unit_file_t type, if you  want  to  treat
368       the files as keystone unit content.
369
370
371
372       keystone_var_lib_t
373
374       -  Set files with the keystone_var_lib_t type, if you want to store the
375       keystone files under the /var/lib directory.
376
377
378
379       keystone_var_run_t
380
381       - Set files with the keystone_var_run_t type, if you want to store  the
382       keystone files under the /run or /var/run directory.
383
384
385
386       Note:  File context can be temporarily modified with the chcon command.
387       If you want to permanently change the file context you need to use  the
388       semanage fcontext command.  This will modify the SELinux labeling data‐
389       base.  You will need to use restorecon to apply the labels.
390
391

COMMANDS

393       semanage fcontext can also be used to manipulate default  file  context
394       mappings.
395
396       semanage  permissive  can  also  be used to manipulate whether or not a
397       process type is permissive.
398
399       semanage module can also be used to enable/disable/install/remove  pol‐
400       icy modules.
401
402       semanage port can also be used to manipulate the port definitions
403
404       semanage boolean can also be used to manipulate the booleans
405
406
407       system-config-selinux is a GUI tool available to customize SELinux pol‐
408       icy settings.
