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 allow users to resolve user passwd entries directly from
61 ldap rather then using a sssd server, you must turn on the authlo‐
62 gin_nsswitch_use_ldap boolean. Disabled by default.
63
64 setsebool -P authlogin_nsswitch_use_ldap 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 confined applications to run with kerberos, you
76 must turn on the kerberos_enabled boolean. Enabled by default.
77
78 setsebool -P kerberos_enabled 1
79
80
81
82 If you want to allow system to run with NIS, you must turn on the
83 nis_enabled boolean. Disabled by default.
84
85 setsebool -P nis_enabled 1
86
87
88
89 If you want to allow confined applications to use nscd shared memory,
90 you must turn on the nscd_use_shm boolean. Disabled by default.
91
92 setsebool -P nscd_use_shm 1
93
94
95
97 The SELinux process type greylist_milter_t can manage files labeled
98 with the following file types. The paths listed are the default paths
99 for these file types. Note the processes UID still need to have DAC
100 permissions.

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