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
13 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
17 For example:
18
19 ps -eZ | grep greylist_milter_t
20
21
22
24 The greylist_milter_t SELinux type can be entered via the greylist_mil‐
25 ter_exec_t file type.
26
27 The default entrypoint paths for the greylist_milter_t domain are the
28 following:
29
30 /usr/sbin/sqlgrey, /usr/sbin/milter-greylist
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 greylist_milter policy is very flexible allowing users to setup their
40 greylist_milter processes in as secure a method as possible.
41
42 The following process types are defined for greylist_milter:
43
44 greylist_milter_t
45
46 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
51
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.
57
58
59
60 If you want to dontaudit all daemons scheduling requests (setsched,
61 sys_nice), you must turn on the daemons_dontaudit_scheduling boolean.
62 Enabled by default.
63
64 setsebool -P daemons_dontaudit_scheduling 1
65
66
67
68 If you want to allow all domains to execute in fips_mode, you must turn
69 on the fips_mode boolean. Enabled by default.
70
71 setsebool -P fips_mode 1
72
73
74
75 If you want to allow system to run with NIS, you must turn on the
76 nis_enabled boolean. Disabled by default.
77
78 setsebool -P nis_enabled 1
79

81
83 The SELinux process type greylist_milter_t can manage files labeled
84 with the following file types. The paths listed are the default paths
85 for these file types. Note the processes UID still need to have DAC
86 permissions.

148 SELinux requires files to have an extended attribute to define the file
149 type.
150
151 You can see the context of a file using the -Z option to ls
152
153 Policy governs the access confined processes have to these files.
154 SELinux greylist_milter policy is very flexible allowing users to setup
155 their greylist_milter processes in as secure a method as possible.
156
157 EQUIVALENCE DIRECTORIES
158
159
160 greylist_milter policy stores data with multiple different file context
161 types under the /var/run/milter-greylist directory. If you would like
162 to store the data in a different directory you can use the semanage
163 command to create an equivalence mapping. If you wanted to store this
164 data under the /srv directory you would execute the following command:
165
166 semanage fcontext -a -e /var/run/milter-greylist /srv/milter-greylist
167 restorecon -R -v /srv/milter-greylist
168
169 STANDARD FILE CONTEXT
170
171 SELinux defines the file context types for the greylist_milter, if you
172 wanted to store files with these types in a different paths, you need
173 to execute the semanage command to specify alternate labeling and then
174 use restorecon to put the labels on disk.
175
176 semanage fcontext -a -t greylist_milter_exec_t '/srv/greylist_mil‐
177 ter/content(/.*)?'
178 restorecon -R -v /srv/mygreylist_milter_content
179
180 Note: SELinux often uses regular expressions to specify labels that
181 match multiple files.
182
183 The following file types are defined for greylist_milter:
184
185
186
187 greylist_milter_data_t
188
189 - Set files with the greylist_milter_data_t type, if you want to treat
190 the files as greylist milter content.
191
192
193 Paths:
194 /var/lib/sqlgrey(/.*)?, /var/lib/milter-greylist(/.*)?,
195 /var/run/milter-greylist(/.*)?, /var/run/sqlgrey.pid,
196 /var/run/milter-greylist.pid
197
198
199 greylist_milter_exec_t
200
201 - Set files with the greylist_milter_exec_t type, if you want to tran‐
202 sition an executable to the greylist_milter_t domain.
203
204
205 Paths:
206 /usr/sbin/sqlgrey, /usr/sbin/milter-greylist
207
208
209 Note: File context can be temporarily modified with the chcon command.
210 If you want to permanently change the file context you need to use the
211 semanage fcontext command. This will modify the SELinux labeling data‐
212 base. You will need to use restorecon to apply the labels.
213
214
216 semanage fcontext can also be used to manipulate default file context
217 mappings.
218
219 semanage permissive can also be used to manipulate whether or not a
220 process type is permissive.
221
222 semanage module can also be used to enable/disable/install/remove pol‐
223 icy modules.
224
225 semanage boolean can also be used to manipulate the booleans
226
227
228 system-config-selinux is a GUI tool available to customize SELinux pol‐
229 icy settings.
