6 glance_scrubber_selinux - Security Enhanced Linux Policy for the
7 glance_scrubber processes
8
10 Security-Enhanced Linux secures the glance_scrubber processes via flex‐
11 ible mandatory access control.
12
13 The glance_scrubber processes execute with the glance_scrubber_t
14 SELinux type. You can check if you have these processes running by exe‐
15 cuting the ps command with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep glance_scrubber_t
20
21
22
24 The glance_scrubber_t SELinux type can be entered via the glance_scrub‐
25 ber_exec_t file type.
26
27 The default entrypoint paths for the glance_scrubber_t domain are the
28 following:
29
30 /usr/bin/glance-scrubber
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 glance_scrubber policy is very flexible allowing users to setup their
40 glance_scrubber processes in as secure a method as possible.
41
42 The following process types are defined for glance_scrubber:
43
44 glance_scrubber_t
45
46 Note: semanage permissive -a glance_scrubber_t can be used to make the
47 process type glance_scrubber_t permissive. SELinux does not deny access
48 to permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
51
53 SELinux policy is customizable based on least access required.
54 glance_scrubber policy is extremely flexible and has several booleans
55 that allow you to manipulate the policy and run glance_scrubber with
56 the tightest access possible.

240 SELinux requires files to have an extended attribute to define the file
241 type.
242
243 You can see the context of a file using the -Z option to ls
244
245 Policy governs the access confined processes have to these files.
246 SELinux glance_scrubber policy is very flexible allowing users to setup
247 their glance_scrubber processes in as secure a method as possible.
248
249 STANDARD FILE CONTEXT
250
251 SELinux defines the file context types for the glance_scrubber, if you
252 wanted to store files with these types in a diffent paths, you need to
253 execute the semanage command to sepecify alternate labeling and then
254 use restorecon to put the labels on disk.
255
256 semanage fcontext -a -t glance_scrubber_unit_file_t
257 '/srv/myglance_scrubber_content(/.*)?'
258 restorecon -R -v /srv/myglance_scrubber_content
259
260 Note: SELinux often uses regular expressions to specify labels that
261 match multiple files.
262
263 The following file types are defined for glance_scrubber:
264
265
266
267 glance_scrubber_exec_t
268
269 - Set files with the glance_scrubber_exec_t type, if you want to tran‐
270 sition an executable to the glance_scrubber_t domain.
271
272
273
274 glance_scrubber_initrc_exec_t
275
276 - Set files with the glance_scrubber_initrc_exec_t type, if you want to
277 transition an executable to the glance_scrubber_initrc_t domain.
278
279
280
281 glance_scrubber_unit_file_t
282
283 - Set files with the glance_scrubber_unit_file_t type, if you want to
284 treat the files as glance scrubber unit content.
285
286
287
288 Note: File context can be temporarily modified with the chcon command.
289 If you want to permanently change the file context you need to use the
290 semanage fcontext command. This will modify the SELinux labeling data‐
291 base. You will need to use restorecon to apply the labels.
292
293
295 semanage fcontext can also be used to manipulate default file context
296 mappings.
297
298 semanage permissive can also be used to manipulate whether or not a
299 process type is permissive.
300
301 semanage module can also be used to enable/disable/install/remove pol‐
302 icy modules.
303
304 semanage boolean can also be used to manipulate the booleans
305
306
307 system-config-selinux is a GUI tool available to customize SELinux pol‐
308 icy settings.
