6 vnstatd_selinux - Security Enhanced Linux Policy for the vnstatd pro‐
7 cesses
8
10 Security-Enhanced Linux secures the vnstatd processes via flexible
11 mandatory access control.
12
13 The vnstatd processes execute with the vnstatd_t SELinux type. You can
14 check if you have these processes running by executing the ps command
15 with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep vnstatd_t
20
21
22
24 The vnstatd_t SELinux type can be entered via the vnstatd_exec_t file
25 type.
26
27 The default entrypoint paths for the vnstatd_t domain are the follow‐
28 ing:
29
30 /usr/sbin/vnstatd
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 vnstatd policy is very flexible allowing users to setup their vnstatd
40 processes in as secure a method as possible.
41
42 The following process types are defined for vnstatd:
43
44 vnstat_t, vnstatd_t
45
46 Note: semanage permissive -a vnstatd_t can be used to make the process
47 type vnstatd_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. vnstatd
54 policy is extremely flexible and has several booleans that allow you to
55 manipulate the policy and run vnstatd with the tightest access possi‐
56 ble.

135 on the global_ssp boolean. Disabled by default.
136
137 setsebool -P global_ssp 1
138
139
140
142 The SELinux process type vnstatd_t can manage files labeled with the
143 following file types. The paths listed are the default paths for these
144 file types. Note the processes UID still need to have DAC permissions.

191 SELinux requires files to have an extended attribute to define the file
192 type.
193
194 You can see the context of a file using the -Z option to ls
195
196 Policy governs the access confined processes have to these files.
197 SELinux vnstatd policy is very flexible allowing users to setup their
198 vnstatd processes in as secure a method as possible.
199
200 STANDARD FILE CONTEXT
201
202 SELinux defines the file context types for the vnstatd, if you wanted
203 to store files with these types in a diffent paths, you need to execute
204 the semanage command to sepecify alternate labeling and then use
205 restorecon to put the labels on disk.
206
207 semanage fcontext -a -t vnstatd_var_run_t '/srv/myvnstatd_con‐
208 tent(/.*)?'
209 restorecon -R -v /srv/myvnstatd_content
210
211 Note: SELinux often uses regular expressions to specify labels that
212 match multiple files.
213
214 The following file types are defined for vnstatd:
215
216
217
218 vnstatd_exec_t
219
220 - Set files with the vnstatd_exec_t type, if you want to transition an
221 executable to the vnstatd_t domain.
222
223
224
225 vnstatd_initrc_exec_t
226
227 - Set files with the vnstatd_initrc_exec_t type, if you want to transi‐
228 tion an executable to the vnstatd_initrc_t domain.
229
230
231
232 vnstatd_var_lib_t
233
234 - Set files with the vnstatd_var_lib_t type, if you want to store the
235 vnstatd files under the /var/lib directory.
236
237
238
239 vnstatd_var_run_t
240
241 - Set files with the vnstatd_var_run_t type, if you want to store the
242 vnstatd files under the /run or /var/run directory.
243
244
245
246 Note: File context can be temporarily modified with the chcon command.
247 If you want to permanently change the file context you need to use the
248 semanage fcontext command. This will modify the SELinux labeling data‐
249 base. You will need to use restorecon to apply the labels.
250
251
253 semanage fcontext can also be used to manipulate default file context
254 mappings.
255
256 semanage permissive can also be used to manipulate whether or not a
257 process type is permissive.
258
259 semanage module can also be used to enable/disable/install/remove pol‐
260 icy modules.
261
262 semanage boolean can also be used to manipulate the booleans
263
264
265 system-config-selinux is a GUI tool available to customize SELinux pol‐
266 icy settings.
