6 greylist_milter_selinux - Security Enhanced Linux Policy for the
7 greylist_milter processes
8
10 Security-Enhanced Linux secures the greylist_milter processes via flex‐
11 ible mandatory access control.
12 The greylist_milter processes execute with the greylist_milter_t
14 SELinux type. You can check if you have these processes running by exe‐
15 cuting the ps command with the -Z qualifier.
16 For example:
18 ps -eZ | grep greylist_milter_t
20
24 The greylist_milter_t SELinux type can be entered via the greylist_mil‐
25 ter_exec_t file type.
26 The default entrypoint paths for the greylist_milter_t domain are the
28 following:
29 /usr/sbin/milter-greylist
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 greylist_milter policy is very flexible allowing users to setup their
40 greylist_milter processes in as secure a method as possible.
41 The following process types are defined for greylist_milter:
43 greylist_milter_t
45 Note: semanage permissive -a greylist_milter_t can be used to make the
47 process type greylist_milter_t permissive. SELinux does not deny access
48 to 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 greylist_milter policy is extremely flexible and has several booleans
55 that allow you to manipulate the policy and run greylist_milter with
56 the tightest 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 greylist_milter_t can manage files labeled
155 with the following file types. The paths listed are the default paths
156 for these file types. Note the processes UID still need to have DAC
157 permissions.

224 SELinux requires files to have an extended attribute to define the file
225 type.
226 You can see the context of a file using the -Z option to ls
228 Policy governs the access confined processes have to these files.
230 SELinux greylist_milter policy is very flexible allowing users to setup
231 their greylist_milter processes in as secure a method as possible.
232 EQUIVALENCE DIRECTORIES
234 greylist_milter policy stores data with multiple different file context
237 types under the /var/run/milter-greylist directory. If you would like
238 to store the data in a different directory you can use the semanage
239 command to create an equivalence mapping. If you wanted to store this
240 data under the /srv dirctory you would execute the following command:
241 semanage fcontext -a -e /var/run/milter-greylist /srv/milter-greylist
243 restorecon -R -v /srv/milter-greylist
244 STANDARD FILE CONTEXT
246 SELinux defines the file context types for the greylist_milter, if you
248 wanted to store files with these types in a diffent paths, you need to
249 execute the semanage command to sepecify alternate labeling and then
250 use restorecon to put the labels on disk.
251 semanage fcontext -a -t greylist_milter_data_t '/srv/mygreylist_mil‐
253 ter_content(/.*)?'
254 restorecon -R -v /srv/mygreylist_milter_content
255 Note: SELinux often uses regular expressions to specify labels that
257 match multiple files.
258 The following file types are defined for greylist_milter:
260 greylist_milter_data_t
264 - Set files with the greylist_milter_data_t type, if you want to treat
266 the files as greylist milter content.
267 Paths:
270 /var/lib/milter-greylist(/.*)?, /var/run/milter-greylist(/.*)?,
271 /var/run/milter-greylist.pid
272 greylist_milter_exec_t
275 - Set files with the greylist_milter_exec_t type, if you want to tran‐
277 sition an executable to the greylist_milter_t domain.
278 Note: File context can be temporarily modified with the chcon command.
282 If you want to permanently change the file context you need to use the
283 semanage fcontext command. This will modify the SELinux labeling data‐
284 base. You will need to use restorecon to apply the labels.
285
288 semanage fcontext can also be used to manipulate default file context
289 mappings.
290 semanage permissive can also be used to manipulate whether or not a
292 process type is permissive.
293 semanage module can also be used to enable/disable/install/remove pol‐
295 icy modules.
296 semanage boolean can also be used to manipulate the booleans
298 system-config-selinux is a GUI tool available to customize SELinux pol‐
301 icy settings.
