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

134 abled by default.

141 The SELinux process type fsdaemon_t can manage files labeled with the
142 following file types. The paths listed are the default paths for these
143 file types. Note the processes UID still need to have DAC permissions.

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 fsdaemon policy is very flexible allowing users to setup their
221 fsdaemon processes in as secure a method as possible.
222
223 STANDARD FILE CONTEXT
224
225 SELinux defines the file context types for the fsdaemon, if you wanted
226 to 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 fsdaemon_var_run_t '/srv/myfsdaemon_con‐
231 tent(/.*)?'
232 restorecon -R -v /srv/myfsdaemon_content
233
234 Note: SELinux often uses regular expressions to specify labels that
235 match multiple files.
236
237 The following file types are defined for fsdaemon:
238
239
240
241 fsdaemon_exec_t
242
243 - Set files with the fsdaemon_exec_t type, if you want to transition an
244 executable to the fsdaemon_t domain.
245
246
247
248 fsdaemon_initrc_exec_t
249
250 - Set files with the fsdaemon_initrc_exec_t type, if you want to tran‐
251 sition an executable to the fsdaemon_initrc_t domain.
252
253
254
255 fsdaemon_tmp_t
256
257 - Set files with the fsdaemon_tmp_t type, if you want to store fsdaemon
258 temporary files in the /tmp directories.
259
260
261
262 fsdaemon_var_run_t
263
264 - Set files with the fsdaemon_var_run_t type, if you want to store the
265 fsdaemon files under the /run or /var/run directory.
266
267
268
269 Note: File context can be temporarily modified with the chcon command.
270 If you want to permanently change the file context you need to use the
271 semanage fcontext command. This will modify the SELinux labeling data‐
272 base. You will need to use restorecon to apply the labels.
273
274
276 semanage fcontext can also be used to manipulate default file context
277 mappings.
278
279 semanage permissive can also be used to manipulate whether or not a
280 process type is permissive.
281
282 semanage module can also be used to enable/disable/install/remove pol‐
283 icy modules.
284
285 semanage boolean can also be used to manipulate the booleans
286
287
288 system-config-selinux is a GUI tool available to customize SELinux pol‐
289 icy settings.
