NAME

6       canna_selinux - Security Enhanced Linux Policy for the canna processes
7

DESCRIPTION

9       Security-Enhanced Linux secures the canna processes via flexible manda‐
10       tory access control.
11
12       The canna processes execute with the  canna_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 canna_t
19
20
21

ENTRYPOINTS

23       The canna_t SELinux type can be entered via the canna_exec_t file type.
24
25       The default entrypoint paths for the canna_t domain are the following:
26
27       /usr/bin/catdic, /usr/sbin/jserver, /usr/bin/cannaping,  /usr/sbin/can‐
28       naserver
29

PROCESS TYPES

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

BOOLEANS

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

MANAGED FILES

168       The SELinux process type canna_t can manage files labeled with the fol‐
169       lowing file types.  The paths listed are the default  paths  for  these
170       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

220       SELinux requires files to have an extended attribute to define the file
221       type.
222
223       You can see the context of a file using the -Z option to ls
224
225       Policy governs the access  confined  processes  have  to  these  files.
226       SELinux  canna  policy  is  very flexible allowing users to setup their
227       canna processes in as secure a method as possible.
228
229       STANDARD FILE CONTEXT
230
231       SELinux defines the file context types for the canna, if you wanted  to
232       store  files  with  these types in a diffent paths, you need to execute
233       the semanage command  to  sepecify  alternate  labeling  and  then  use
234       restorecon to put the labels on disk.
235
236       semanage fcontext -a -t canna_var_run_t '/srv/mycanna_content(/.*)?'
237       restorecon -R -v /srv/mycanna_content
238
239       Note:  SELinux  often  uses  regular expressions to specify labels that
240       match multiple files.
241
242       The following file types are defined for canna:
243
244
245
246       canna_exec_t
247
248       - Set files with the canna_exec_t type, if you want  to  transition  an
249       executable to the canna_t domain.
250
251
252       Paths:
253            /usr/bin/catdic,       /usr/sbin/jserver,      /usr/bin/cannaping,
254            /usr/sbin/cannaserver
255
256
257       canna_initrc_exec_t
258
259       - Set files with the canna_initrc_exec_t type, if you want  to  transi‐
260       tion an executable to the canna_initrc_t domain.
261
262
263
264       canna_log_t
265
266       - Set files with the canna_log_t type, if you want to treat the data as
267       canna log data, usually stored under the /var/log directory.
268
269
270       Paths:
271            /var/log/wnn(/.*)?, /var/log/canna(/.*)?
272
273
274       canna_var_lib_t
275
276       - Set files with the canna_var_lib_t type, if you  want  to  store  the
277       canna files under the /var/lib directory.
278
279
280       Paths:
281            /var/lib/wnn/dic(/.*)?, /var/lib/canna/dic(/.*)?
282
283
284       canna_var_run_t
285
286       -  Set  files  with  the canna_var_run_t type, if you want to store the
287       canna files under the /run or /var/run directory.
288
289
290       Paths:
291            /var/run/wnn-unix(/.*),                   /var/run/.iroha_unix/.*,
292            /var/run/.iroha_unix
293
294
295       Note:  File context can be temporarily modified with the chcon command.
296       If you want to permanently change the file context you need to use  the
297       semanage fcontext command.  This will modify the SELinux labeling data‐
298       base.  You will need to use restorecon to apply the labels.
299
300

COMMANDS

302       semanage fcontext can also be used to manipulate default  file  context
303       mappings.
304
305       semanage  permissive  can  also  be used to manipulate whether or not a
306       process type is permissive.
307
308       semanage module can also be used to enable/disable/install/remove  pol‐
309       icy modules.
310
311       semanage boolean can also be used to manipulate the booleans
312
313
314       system-config-selinux is a GUI tool available to customize SELinux pol‐
315       icy settings.
