6 polipo_selinux - Security Enhanced Linux Policy for the polipo pro‐
7 cesses
8
10 Security-Enhanced Linux secures the polipo processes via flexible
11 mandatory access control.
12
13 The polipo processes execute with the polipo_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 polipo_t
20
21
22
24 The polipo_t SELinux type can be entered via the polipo_exec_t file
25 type.
26
27 The default entrypoint paths for the polipo_t domain are the following:
28
29 /usr/bin/polipo
30
32 SELinux defines process types (domains) for each process running on the
33 system
34
35 You can see the context of a process using the -Z option to ps
36
37 Policy governs the access confined processes have to files. SELinux
38 polipo policy is very flexible allowing users to setup their polipo
39 processes in as secure a method as possible.
40
41 The following process types are defined for polipo:
42
43 polipo_t, polipo_session_t
44
45 Note: semanage permissive -a polipo_t can be used to make the process
46 type polipo_t permissive. SELinux does not deny access to permissive
47 process types, but the AVC (SELinux denials) messages are still gener‐
48 ated.
49
50
52 SELinux policy is customizable based on least access required. polipo
53 policy is extremely flexible and has several booleans that allow you to
54 manipulate the policy and run polipo with the tightest access possible.

249 SELinux requires files to have an extended attribute to define the file
250 type.
251
252 You can see the context of a file using the -Z option to ls
253
254 Policy governs the access confined processes have to these files.
255 SELinux polipo policy is very flexible allowing users to setup their
256 polipo processes in as secure a method as possible.
257
258 STANDARD FILE CONTEXT
259
260 SELinux defines the file context types for the polipo, if you wanted to
261 store files with these types in a diffent paths, you need to execute
262 the semanage command to sepecify alternate labeling and then use
263 restorecon to put the labels on disk.
264
265 semanage fcontext -a -t polipo_unit_file_t '/srv/mypolipo_con‐
266 tent(/.*)?'
267 restorecon -R -v /srv/mypolipo_content
268
269 Note: SELinux often uses regular expressions to specify labels that
270 match multiple files.
271
272 The following file types are defined for polipo:
273
274
275
276 polipo_cache_home_t
277
278 - Set files with the polipo_cache_home_t type, if you want to store
279 polipo cache files in the users home directory.
280
281
282
283 polipo_cache_t
284
285 - Set files with the polipo_cache_t type, if you want to store the
286 files under the /var/cache directory.
287
288
289
290 polipo_config_home_t
291
292 - Set files with the polipo_config_home_t type, if you want to store
293 polipo config files in the users home directory.
294
295
296
297 polipo_etc_t
298
299 - Set files with the polipo_etc_t type, if you want to store polipo
300 files in the /etc directories.
301
302
303
304 polipo_exec_t
305
306 - Set files with the polipo_exec_t type, if you want to transition an
307 executable to the polipo_t domain.
308
309
310
311 polipo_initrc_exec_t
312
313 - Set files with the polipo_initrc_exec_t type, if you want to transi‐
314 tion an executable to the polipo_initrc_t domain.
315
316
317
318 polipo_log_t
319
320 - Set files with the polipo_log_t type, if you want to treat the data
321 as polipo log data, usually stored under the /var/log directory.
322
323
324
325 polipo_pid_t
326
327 - Set files with the polipo_pid_t type, if you want to store the polipo
328 files under the /run directory.
329
330
331
332 polipo_unit_file_t
333
334 - Set files with the polipo_unit_file_t type, if you want to treat the
335 files as polipo unit content.
336
337
338
339 Note: File context can be temporarily modified with the chcon command.
340 If you want to permanently change the file context you need to use the
341 semanage fcontext command. This will modify the SELinux labeling data‐
342 base. You will need to use restorecon to apply the labels.
343
344
346 semanage fcontext can also be used to manipulate default file context
347 mappings.
348
349 semanage permissive can also be used to manipulate whether or not a
350 process type is permissive.
351
352 semanage module can also be used to enable/disable/install/remove pol‐
353 icy modules.
354
355 semanage boolean can also be used to manipulate the booleans
356
357
358 system-config-selinux is a GUI tool available to customize SELinux pol‐
359 icy settings.
