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 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 For example:
18 ps -eZ | grep dkim_milter_t
20
24 The dkim_milter_t SELinux type can be entered via the dkim_mil‐
25 ter_exec_t file type.
26 The default entrypoint paths for the dkim_milter_t domain are the fol‐
28 lowing:
29 /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 You can see the context of a process using the -Z option to ps
37 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 The following process types are defined for dkim_milter:
43 dkim_milter_t
45 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
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.

154 The SELinux process type dkim_milter_t can manage files labeled with
155 the following file types. The paths listed are the default paths for
156 these file types. Note the processes UID still need to have DAC per‐
157 missions.

227 SELinux requires files to have an extended attribute to define the file
228 type.
229 You can see the context of a file using the -Z option to ls
231 Policy governs the access confined processes have to these files.
233 SELinux dkim_milter policy is very flexible allowing users to setup
234 their dkim_milter processes in as secure a method as possible.
235 STANDARD FILE CONTEXT
237 SELinux defines the file context types for the dkim_milter, if you
239 wanted to store files with these types in a diffent paths, you need to
240 execute the semanage command to sepecify alternate labeling and then
241 use restorecon to put the labels on disk.
242 semanage fcontext -a -t dkim_milter_private_key_t '/srv/mydkim_mil‐
244 ter_content(/.*)?'
245 restorecon -R -v /srv/mydkim_milter_content
246 Note: SELinux often uses regular expressions to specify labels that
248 match multiple files.
249 The following file types are defined for dkim_milter:
251 dkim_milter_data_t
255 - Set files with the dkim_milter_data_t type, if you want to treat the
257 files as dkim milter content.
258 Paths:
261 /var/run/opendkim(/.*)?, /var/run/opendmarc(/.*)?,
262 /var/spool/opendkim(/.*)?, /var/lib/dkim-milter(/.*)?,
263 /var/run/dkim-milter(/.*)?, /var/spool/opendmarc(/.*)?
264 dkim_milter_exec_t
267 - Set files with the dkim_milter_exec_t type, if you want to transition
269 an executable to the dkim_milter_t domain.
270 Paths:
273 /usr/sbin/opendkim, /usr/sbin/opendmarc, /usr/sbin/dkim-filter
274 dkim_milter_private_key_t
277 - Set files with the dkim_milter_private_key_t type, if you want to
279 treat the files as dkim milter private key data.
280 Note: File context can be temporarily modified with the chcon command.
284 If you want to permanently change the file context you need to use the
285 semanage fcontext command. This will modify the SELinux labeling data‐
286 base. You will need to use restorecon to apply the labels.
287
290 semanage fcontext can also be used to manipulate default file context
291 mappings.
292 semanage permissive can also be used to manipulate whether or not a
294 process type is permissive.
295 semanage module can also be used to enable/disable/install/remove pol‐
297 icy modules.
298 semanage boolean can also be used to manipulate the booleans
300 system-config-selinux is a GUI tool available to customize SELinux pol‐
303 icy settings.
