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 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 For example:
18 ps -eZ | grep regex_milter_t
20
24 The regex_milter_t SELinux type can be entered via the regex_mil‐
25 ter_exec_t file type.
26 The default entrypoint paths for the regex_milter_t domain are the fol‐
28 lowing:
29 /usr/sbin/milter-regex
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 regex_milter policy is very flexible allowing users to setup their
40 regex_milter processes in as secure a method as possible.
41 The following process types are defined for regex_milter:
43 regex_milter_t
45 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
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.

147 you must turn on the nscd_use_shm boolean. Enabled by default.
148 setsebool -P nscd_use_shm 1

154 The SELinux process type regex_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.

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