6 ddclient_selinux - Security Enhanced Linux Policy for the ddclient pro‐
7 cesses
8
10 Security-Enhanced Linux secures the ddclient processes via flexible
11 mandatory access control.
12
13 The ddclient processes execute with the ddclient_t SELinux type. You
14 can check if you have these processes running by executing the ps com‐
15 mand with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep ddclient_t
20
21
22
24 The ddclient_t SELinux type can be entered via the ddclient_exec_t file
25 type.
26
27 The default entrypoint paths for the ddclient_t domain are the follow‐
28 ing:
29
30 /usr/sbin/ddtcd, /usr/sbin/ddclient
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 ddclient policy is very flexible allowing users to setup their ddclient
40 processes in as secure a method as possible.
41
42 The following process types are defined for ddclient:
43
44 ddclient_t
45
46 Note: semanage permissive -a ddclient_t can be used to make the process
47 type ddclient_t permissive. SELinux does not deny access to permissive
48 process types, but the AVC (SELinux denials) messages are still gener‐
49 ated.
50
51
53 SELinux policy is customizable based on least access required.
54 ddclient policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run ddclient with the tightest
56 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. Enabled by default.
91
92 setsebool -P nscd_use_shm 1
93
94
95
97 The SELinux process type ddclient_t can manage files labeled with the
98 following file types. The paths listed are the default paths for these
99 file types. Note the processes UID still need to have DAC permissions.

154 SELinux requires files to have an extended attribute to define the file
155 type.
156
157 You can see the context of a file using the -Z option to ls
158
159 Policy governs the access confined processes have to these files.
160 SELinux ddclient policy is very flexible allowing users to setup their
161 ddclient processes in as secure a method as possible.
162
163 STANDARD FILE CONTEXT
164
165 SELinux defines the file context types for the ddclient, if you wanted
166 to store files with these types in a diffent paths, you need to execute
167 the semanage command to sepecify alternate labeling and then use
168 restorecon to put the labels on disk.
169
170 semanage fcontext -a -t ddclient_var_run_t '/srv/myddclient_con‐
171 tent(/.*)?'
172 restorecon -R -v /srv/myddclient_content
173
174 Note: SELinux often uses regular expressions to specify labels that
175 match multiple files.
176
177 The following file types are defined for ddclient:
178
179
180
181 ddclient_etc_t
182
183 - Set files with the ddclient_etc_t type, if you want to store ddclient
184 files in the /etc directories.
185
186
187 Paths:
188 /etc/ddtcd.conf, /etc/ddclient.conf
189
190
191 ddclient_exec_t
192
193 - Set files with the ddclient_exec_t type, if you want to transition an
194 executable to the ddclient_t domain.
195
196
197 Paths:
198 /usr/sbin/ddtcd, /usr/sbin/ddclient
199
200
201 ddclient_initrc_exec_t
202
203 - Set files with the ddclient_initrc_exec_t type, if you want to tran‐
204 sition an executable to the ddclient_initrc_t domain.
205
206
207
208 ddclient_log_t
209
210 - Set files with the ddclient_log_t type, if you want to treat the data
211 as ddclient log data, usually stored under the /var/log directory.
212
213
214
215 ddclient_tmp_t
216
217 - Set files with the ddclient_tmp_t type, if you want to store ddclient
218 temporary files in the /tmp directories.
219
220
221
222 ddclient_var_lib_t
223
224 - Set files with the ddclient_var_lib_t type, if you want to store the
225 ddclient files under the /var/lib directory.
226
227
228
229 ddclient_var_run_t
230
231 - Set files with the ddclient_var_run_t type, if you want to store the
232 ddclient files under the /run or /var/run directory.
233
234
235 Paths:
236 /var/run/ddtcd.pid, /var/run/ddclient.pid
237
238
239 ddclient_var_t
240
241 - Set files with the ddclient_var_t type, if you want to store the ddcl
242 files under the /var directory.
243
244
245
246 Note: File context can be temporarily modified with the chcon command.
247 If you want to permanently change the file context you need to use the
248 semanage fcontext command. This will modify the SELinux labeling data‐
249 base. You will need to use restorecon to apply the labels.
250
251
253 semanage fcontext can also be used to manipulate default file context
254 mappings.
255
256 semanage permissive can also be used to manipulate whether or not a
257 process type is permissive.
258
259 semanage module can also be used to enable/disable/install/remove pol‐
260 icy modules.
261
262 semanage boolean can also be used to manipulate the booleans
263
264
265 system-config-selinux is a GUI tool available to customize SELinux pol‐
266 icy settings.
