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.
57 If you want to allow all domains to execute in fips_mode, you must turn
61 on the fips_mode boolean. Enabled by default.
62 setsebool -P fips_mode 1

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

142 SELinux requires files to have an extended attribute to define the file
143 type.
144 You can see the context of a file using the -Z option to ls
146 Policy governs the access confined processes have to these files.
148 SELinux dkim_milter policy is very flexible allowing users to setup
149 their dkim_milter processes in as secure a method as possible.
150 STANDARD FILE CONTEXT
152 SELinux defines the file context types for the dkim_milter, if you
154 wanted to store files with these types in a diffent paths, you need to
155 execute the semanage command to specify alternate labeling and then use
156 restorecon to put the labels on disk.
157 semanage fcontext -a -t dkim_milter_tmp_t '/srv/mydkim_milter_con‐
159 tent(/.*)?'
160 restorecon -R -v /srv/mydkim_milter_content
161 Note: SELinux often uses regular expressions to specify labels that
163 match multiple files.
164 The following file types are defined for dkim_milter:
166 dkim_milter_data_t
170 - Set files with the dkim_milter_data_t type, if you want to treat the
172 files as dkim milter content.
173 Paths:
176 /var/run/opendkim(/.*)?, /var/run/opendmarc(/.*)?,
177 /var/spool/opendkim(/.*)?, /var/lib/dkim-milter(/.*)?,
178 /var/run/dkim-milter(/.*)?, /var/spool/opendmarc(/.*)?
179 dkim_milter_exec_t
182 - Set files with the dkim_milter_exec_t type, if you want to transition
184 an executable to the dkim_milter_t domain.
185 Paths:
188 /usr/sbin/opendkim, /usr/sbin/opendmarc, /usr/sbin/dkim-filter
189 dkim_milter_private_key_t
192 - Set files with the dkim_milter_private_key_t type, if you want to
194 treat the files as dkim milter private key data.
195 dkim_milter_tmp_t
199 - Set files with the dkim_milter_tmp_t type, if you want to store dkim
201 milter temporary files in the /tmp directories.
202 Note: File context can be temporarily modified with the chcon command.
206 If you want to permanently change the file context you need to use the
207 semanage fcontext command. This will modify the SELinux labeling data‐
208 base. You will need to use restorecon to apply the labels.
209
212 semanage fcontext can also be used to manipulate default file context
213 mappings.
214 semanage permissive can also be used to manipulate whether or not a
216 process type is permissive.
217 semanage module can also be used to enable/disable/install/remove pol‐
219 icy modules.
220 semanage boolean can also be used to manipulate the booleans
222 system-config-selinux is a GUI tool available to customize SELinux pol‐
225 icy settings.
