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

172 the following file types. The paths listed are the default paths for
173 these file types. Note the processes UID still need to have DAC per‐
174 missions.

225 SELinux requires files to have an extended attribute to define the file
226 type.
227
228 You can see the context of a file using the -Z option to ls
229
230 Policy governs the access confined processes have to these files.
231 SELinux dkim_milter policy is very flexible allowing users to setup
232 their dkim_milter processes in as secure a method as possible.
233
234 STANDARD FILE CONTEXT
235
236 SELinux defines the file context types for the dkim_milter, if you
237 wanted to store files with these types in a diffent paths, you need to
238 execute the semanage command to sepecify alternate labeling and then
239 use restorecon to put the labels on disk.
240
241 semanage fcontext -a -t dkim_milter_tmp_t '/srv/mydkim_milter_con‐
242 tent(/.*)?'
243 restorecon -R -v /srv/mydkim_milter_content
244
245 Note: SELinux often uses regular expressions to specify labels that
246 match multiple files.
247
248 The following file types are defined for dkim_milter:
249
250
251
252 dkim_milter_data_t
253
254 - Set files with the dkim_milter_data_t type, if you want to treat the
255 files as dkim milter content.
256
257
258 Paths:
259 /var/run/opendkim(/.*)?, /var/run/opendmarc(/.*)?,
260 /var/spool/opendkim(/.*)?, /var/lib/dkim-milter(/.*)?,
261 /var/run/dkim-milter(/.*)?, /var/spool/opendmarc(/.*)?
262
263
264 dkim_milter_exec_t
265
266 - Set files with the dkim_milter_exec_t type, if you want to transition
267 an executable to the dkim_milter_t domain.
268
269
270 Paths:
271 /usr/sbin/opendkim, /usr/sbin/opendmarc, /usr/sbin/dkim-filter
272
273
274 dkim_milter_private_key_t
275
276 - Set files with the dkim_milter_private_key_t type, if you want to
277 treat the files as dkim milter private key data.
278
279
280
281 dkim_milter_tmp_t
282
283 - Set files with the dkim_milter_tmp_t type, if you want to store dkim
284 milter temporary files in the /tmp directories.
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.
