NAME

6       fsdaemon_selinux - Security Enhanced Linux Policy for the fsdaemon pro‐
7       cesses
8

DESCRIPTION

10       Security-Enhanced Linux secures the  fsdaemon  processes  via  flexible
11       mandatory access control.
12
13       The  fsdaemon  processes  execute with the fsdaemon_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 fsdaemon_t
20
21
22

ENTRYPOINTS

24       The fsdaemon_t SELinux type can be entered via the fsdaemon_exec_t file
25       type.
26
27       The default entrypoint paths for the fsdaemon_t domain are the  follow‐
28       ing:
29
30       /usr/sbin/smartd
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       fsdaemon policy is very flexible allowing users to setup their fsdaemon
40       processes in as secure a method as possible.
41
42       The following process types are defined for fsdaemon:
43
44       fsdaemon_t
45
46       Note: semanage permissive -a fsdaemon_t can be used to make the process
47       type  fsdaemon_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.  fsdae‐
54       mon policy is extremely flexible and has several  booleans  that  allow
55       you  to manipulate the policy and run fsdaemon with the tightest access
56       possible.

172       following file types.  The paths listed are the default paths for these
173       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

227       SELinux requires files to have an extended attribute to define the file
228       type.
229
230       You can see the context of a file using the -Z option to ls
231
232       Policy  governs  the  access  confined  processes  have to these files.
233       SELinux fsdaemon policy is very flexible allowing users to setup  their
234       fsdaemon processes in as secure a method as possible.
235
236       STANDARD FILE CONTEXT
237
238       SELinux  defines the file context types for the fsdaemon, if you wanted
239       to store files with these types in a diffent paths, you need to execute
240       the  semanage  command  to  sepecify  alternate  labeling  and then use
241       restorecon to put the labels on disk.
242
243       semanage  fcontext  -a  -t   fsdaemon_var_run_t   '/srv/myfsdaemon_con‐
244       tent(/.*)?'
245       restorecon -R -v /srv/myfsdaemon_content
246
247       Note:  SELinux  often  uses  regular expressions to specify labels that
248       match multiple files.
249
250       The following file types are defined for fsdaemon:
251
252
253
254       fsdaemon_exec_t
255
256       - Set files with the fsdaemon_exec_t type, if you want to transition an
257       executable to the fsdaemon_t domain.
258
259
260
261       fsdaemon_initrc_exec_t
262
263       -  Set files with the fsdaemon_initrc_exec_t type, if you want to tran‐
264       sition an executable to the fsdaemon_initrc_t domain.
265
266
267
268       fsdaemon_tmp_t
269
270       - Set files with the fsdaemon_tmp_t type, if you want to store fsdaemon
271       temporary files in the /tmp directories.
272
273
274
275       fsdaemon_var_lib_t
276
277       -  Set files with the fsdaemon_var_lib_t type, if you want to store the
278       fsdaemon files under the /var/lib directory.
279
280
281
282       fsdaemon_var_run_t
283
284       - Set files with the fsdaemon_var_run_t type, if you want to store  the
285       fsdaemon files under the /run or /var/run directory.
286
287
288
289       Note:  File context can be temporarily modified with the chcon command.
290       If you want to permanently change the file context you need to use  the
291       semanage fcontext command.  This will modify the SELinux labeling data‐
292       base.  You will need to use restorecon to apply the labels.
293
294

COMMANDS

296       semanage fcontext can also be used to manipulate default  file  context
297       mappings.
298
299       semanage  permissive  can  also  be used to manipulate whether or not a
300       process type is permissive.
301
302       semanage module can also be used to enable/disable/install/remove  pol‐
303       icy modules.
304
305       semanage boolean can also be used to manipulate the booleans
306
307
308       system-config-selinux is a GUI tool available to customize SELinux pol‐
309       icy settings.
