6 firewalld_selinux - Security Enhanced Linux Policy for the firewalld
7 processes
8
10 Security-Enhanced Linux secures the firewalld processes via flexible
11 mandatory access control.
12
13 The firewalld processes execute with the firewalld_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 firewalld_t
20
21
22
24 The firewalld_t SELinux type can be entered via the firewalld_exec_t
25 file type.
26
27 The default entrypoint paths for the firewalld_t domain are the follow‐
28 ing:
29
30 /usr/sbin/firewalld
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 firewalld policy is very flexible allowing users to setup their fire‐
40 walld processes in as secure a method as possible.
41
42 The following process types are defined for firewalld:
43
44 firewalld_t
45
46 Note: semanage permissive -a firewalld_t can be used to make the
47 process type firewalld_t permissive. SELinux does not deny access to
48 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. fire‐
54 walld policy is extremely flexible and has several booleans that allow
55 you to manipulate the policy and run firewalld with the tightest access
56 possible.

245 SELinux requires files to have an extended attribute to define the file
246 type.
247
248 You can see the context of a file using the -Z option to ls
249
250 Policy governs the access confined processes have to these files.
251 SELinux firewalld policy is very flexible allowing users to setup their
252 firewalld processes in as secure a method as possible.
253
254 EQUIVALENCE DIRECTORIES
255
256
257 firewalld policy stores data with multiple different file context types
258 under the /var/run/firewalld directory. If you would like to store the
259 data in a different directory you can use the semanage command to cre‐
260 ate an equivalence mapping. If you wanted to store this data under the
261 /srv dirctory you would execute the following command:
262
263 semanage fcontext -a -e /var/run/firewalld /srv/firewalld
264 restorecon -R -v /srv/firewalld
265
266 STANDARD FILE CONTEXT
267
268 SELinux defines the file context types for the firewalld, if you wanted
269 to store files with these types in a diffent paths, you need to execute
270 the semanage command to sepecify alternate labeling and then use
271 restorecon to put the labels on disk.
272
273 semanage fcontext -a -t firewalld_var_run_t '/srv/myfirewalld_con‐
274 tent(/.*)?'
275 restorecon -R -v /srv/myfirewalld_content
276
277 Note: SELinux often uses regular expressions to specify labels that
278 match multiple files.
279
280 The following file types are defined for firewalld:
281
282
283
284 firewalld_etc_rw_t
285
286 - Set files with the firewalld_etc_rw_t type, if you want to treat the
287 files as firewalld etc read/write content.
288
289
290
291 firewalld_exec_t
292
293 - Set files with the firewalld_exec_t type, if you want to transition
294 an executable to the firewalld_t domain.
295
296
297
298 firewalld_initrc_exec_t
299
300 - Set files with the firewalld_initrc_exec_t type, if you want to tran‐
301 sition an executable to the firewalld_initrc_t domain.
302
303
304
305 firewalld_tmp_t
306
307 - Set files with the firewalld_tmp_t type, if you want to store fire‐
308 walld temporary files in the /tmp directories.
309
310
311
312 firewalld_tmpfs_t
313
314 - Set files with the firewalld_tmpfs_t type, if you want to store fire‐
315 walld files on a tmpfs file system.
316
317
318
319 firewalld_unit_file_t
320
321 - Set files with the firewalld_unit_file_t type, if you want to treat
322 the files as firewalld unit content.
323
324
325
326 firewalld_var_log_t
327
328 - Set files with the firewalld_var_log_t type, if you want to treat the
329 data as firewalld var log data, usually stored under the /var/log
330 directory.
331
332
333
334 firewalld_var_run_t
335
336 - Set files with the firewalld_var_run_t type, if you want to store the
337 firewalld files under the /run or /var/run directory.
338
339
340 Paths:
341 /var/run/firewalld(/.*)?, /var/run/firewalld.pid
342
343
344 Note: File context can be temporarily modified with the chcon command.
345 If you want to permanently change the file context you need to use the
346 semanage fcontext command. This will modify the SELinux labeling data‐
347 base. You will need to use restorecon to apply the labels.
348
349
351 semanage fcontext can also be used to manipulate default file context
352 mappings.
353
354 semanage permissive can also be used to manipulate whether or not a
355 process type is permissive.
356
357 semanage module can also be used to enable/disable/install/remove pol‐
358 icy modules.
359
360 semanage boolean can also be used to manipulate the booleans
361
362
363 system-config-selinux is a GUI tool available to customize SELinux pol‐
364 icy settings.
