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
64
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.

124 SELinux requires files to have an extended attribute to define the file
125 type.
126 You can see the context of a file using the -Z option to ls
128 Policy governs the access confined processes have to these files.
130 SELinux dkim_milter policy is very flexible allowing users to setup
131 their dkim_milter processes in as secure a method as possible.
132 STANDARD FILE CONTEXT
134 SELinux defines the file context types for the dkim_milter, if you
136 wanted to store files with these types in a diffent paths, you need to
137 execute the semanage command to sepecify alternate labeling and then
138 use restorecon to put the labels on disk.
139 semanage fcontext -a -t dkim_milter_tmp_t '/srv/mydkim_milter_con‐
141 tent(/.*)?'
142 restorecon -R -v /srv/mydkim_milter_content
143 Note: SELinux often uses regular expressions to specify labels that
145 match multiple files.
146 The following file types are defined for dkim_milter:
148 dkim_milter_data_t
152 - Set files with the dkim_milter_data_t type, if you want to treat the
154 files as dkim milter content.
155 Paths:
158 /var/run/opendkim(/.*)?, /var/run/opendmarc(/.*)?,
159 /var/spool/opendkim(/.*)?, /var/lib/dkim-milter(/.*)?,
160 /var/run/dkim-milter(/.*)?, /var/spool/opendmarc(/.*)?
161 dkim_milter_exec_t
164 - Set files with the dkim_milter_exec_t type, if you want to transition
166 an executable to the dkim_milter_t domain.
167 Paths:
170 /usr/sbin/opendkim, /usr/sbin/opendmarc, /usr/sbin/dkim-filter
171 dkim_milter_private_key_t
174 - Set files with the dkim_milter_private_key_t type, if you want to
176 treat the files as dkim milter private key data.
177 dkim_milter_tmp_t
181 - Set files with the dkim_milter_tmp_t type, if you want to store dkim
183 milter temporary files in the /tmp directories.
184 Note: File context can be temporarily modified with the chcon command.
188 If you want to permanently change the file context you need to use the
189 semanage fcontext command. This will modify the SELinux labeling data‐
190 base. You will need to use restorecon to apply the labels.
191
194 semanage fcontext can also be used to manipulate default file context
195 mappings.
196 semanage permissive can also be used to manipulate whether or not a
198 process type is permissive.
199 semanage module can also be used to enable/disable/install/remove pol‐
201 icy modules.
202 semanage boolean can also be used to manipulate the booleans
204 system-config-selinux is a GUI tool available to customize SELinux pol‐
207 icy settings.
