NAME

6       ddclient_selinux - Security Enhanced Linux Policy for the ddclient pro‐
7       cesses
8

DESCRIPTION

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

ENTRYPOINTS

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

PROCESS TYPES

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

BOOLEANS

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. Disabled by default.
91
92       setsebool -P nscd_use_shm 1

MANAGED FILES

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.

FILE CONTEXTS

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

COMMANDS

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.
