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

171 The SELinux process type regex_milter_t can manage files labeled with
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.

217 SELinux requires files to have an extended attribute to define the file
218 type.
219
220 You can see the context of a file using the -Z option to ls
221
222 Policy governs the access confined processes have to these files.
223 SELinux regex_milter policy is very flexible allowing users to setup
224 their regex_milter processes in as secure a method as possible.
225
226 STANDARD FILE CONTEXT
227
228 SELinux defines the file context types for the regex_milter, if you
229 wanted to store files with these types in a diffent paths, you need to
230 execute the semanage command to sepecify alternate labeling and then
231 use restorecon to put the labels on disk.
232
233 semanage fcontext -a -t regex_milter_data_t '/srv/myregex_milter_con‐
234 tent(/.*)?'
235 restorecon -R -v /srv/myregex_milter_content
236
237 Note: SELinux often uses regular expressions to specify labels that
238 match multiple files.
239
240 The following file types are defined for regex_milter:
241
242
243
244 regex_milter_data_t
245
246 - Set files with the regex_milter_data_t type, if you want to treat the
247 files as regex milter content.
248
249
250
251 regex_milter_exec_t
252
253 - Set files with the regex_milter_exec_t type, if you want to transi‐
254 tion an executable to the regex_milter_t domain.
255
256
257
258 Note: File context can be temporarily modified with the chcon command.
259 If you want to permanently change the file context you need to use the
260 semanage fcontext command. This will modify the SELinux labeling data‐
261 base. You will need to use restorecon to apply the labels.
262
263
265 semanage fcontext can also be used to manipulate default file context
266 mappings.
267
268 semanage permissive can also be used to manipulate whether or not a
269 process type is permissive.
270
271 semanage module can also be used to enable/disable/install/remove pol‐
272 icy modules.
273
274 semanage boolean can also be used to manipulate the booleans
275
276
277 system-config-selinux is a GUI tool available to customize SELinux pol‐
278 icy settings.
