NAME

6       pdns_selinux - Security Enhanced Linux Policy for the pdns processes
7

DESCRIPTION

9       Security-Enhanced  Linux secures the pdns processes via flexible manda‐
10       tory access control.
11
12       The pdns processes execute with the pdns_t SELinux type. You can  check
13       if  you  have  these processes running by executing the ps command with
14       the -Z qualifier.
15
16       For example:
17
18       ps -eZ | grep pdns_t
19
20
21

ENTRYPOINTS

23       The pdns_t SELinux type can be entered via the pdns_exec_t file type.
24
25       The default entrypoint paths for the pdns_t domain are the following:
26
27       /usr/sbin/pdns_server
28

PROCESS TYPES

30       SELinux defines process types (domains) for each process running on the
31       system
32
33       You can see the context of a process using the -Z option to ps
34
35       Policy  governs  the  access confined processes have to files.  SELinux
36       pdns policy is very flexible allowing users to setup  their  pdns  pro‐
37       cesses in as secure a method as possible.
38
39       The following process types are defined for pdns:
40
41       pdns_t, pdns_control_t
42
43       Note:  semanage  permissive  -a  pdns_t can be used to make the process
44       type pdns_t permissive. SELinux does  not  deny  access  to  permissive
45       process  types, but the AVC (SELinux denials) messages are still gener‐
46       ated.
47
48

BOOLEANS

50       SELinux policy is customizable based on least  access  required.   pdns
51       policy is extremely flexible and has several booleans that allow you to
52       manipulate the policy and run pdns with the tightest access possible.
53
54
55
56       If you want to allow PowerDNS to connect to databases over the network,
57       you  must  turn on the pdns_can_network_connect_db boolean. Disabled by
58       default.
59
60       setsebool -P pdns_can_network_connect_db 1
61
62
63
64       If you want to dontaudit all  daemons  scheduling  requests  (setsched,
65       sys_nice),  you  must turn on the daemons_dontaudit_scheduling boolean.
66       Enabled by default.
67
68       setsebool -P daemons_dontaudit_scheduling 1
69
70
71
72       If you want to allow all domains to execute in fips_mode, you must turn
73       on the fips_mode boolean. Enabled by default.
74
75       setsebool -P fips_mode 1
76
77
78
79       If  you  want  to  allow  system  to run with NIS, you must turn on the
80       nis_enabled boolean. Disabled by default.
81
82       setsebool -P nis_enabled 1
83
84
85

MANAGED FILES

87       The SELinux process type pdns_t can manage files labeled with the  fol‐
88       lowing  file  types.   The paths listed are the default paths for these
89       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

152       SELinux requires files to have an extended attribute to define the file
153       type.
154
155       You can see the context of a file using the -Z option to ls
156
157       Policy  governs  the  access  confined  processes  have to these files.
158       SELinux pdns policy is very flexible allowing users to setup their pdns
159       processes in as secure a method as possible.
160
161       STANDARD FILE CONTEXT
162
163       SELinux  defines  the file context types for the pdns, if you wanted to
164       store files with these types in a different paths, you need to  execute
165       the  semanage  command  to  specify alternate labeling and then use re‐
166       storecon to put the labels on disk.
167
168       semanage fcontext -a -t pdns_exec_t '/srv/pdns/content(/.*)?'
169       restorecon -R -v /srv/mypdns_content
170
171       Note: SELinux often uses regular expressions  to  specify  labels  that
172       match multiple files.
173
174       The following file types are defined for pdns:
175
176
177
178       pdns_conf_t
179
180       -  Set  files with the pdns_conf_t type, if you want to treat the files
181       as pdns configuration data, usually stored under the /etc directory.
182
183
184
185       pdns_control_exec_t
186
187       - Set files with the pdns_control_exec_t type, if you want  to  transi‐
188       tion an executable to the pdns_control_t domain.
189
190
191
192       pdns_exec_t
193
194       - Set files with the pdns_exec_t type, if you want to transition an ex‐
195       ecutable to the pdns_t domain.
196
197
198
199       pdns_unit_file_t
200
201       - Set files with the pdns_unit_file_t type, if you want  to  treat  the
202       files as pdns unit content.
203
204
205
206       pdns_var_lib_t
207
208       - Set files with the pdns_var_lib_t type, if you want to store the pdns
209       files under the /var/lib directory.
210
211
212
213       pdns_var_run_t
214
215       - Set files with the pdns_var_run_t type, if you want to store the pdns
216       files under the /run or /var/run directory.
217
218
219       Paths:
220            /var/run/pdns.pid, /var/run/pdns.controlsocket
221
222
223       Note:  File context can be temporarily modified with the chcon command.
224       If you want to permanently change the file context you need to use  the
225       semanage fcontext command.  This will modify the SELinux labeling data‐
226       base.  You will need to use restorecon to apply the labels.
227
228

COMMANDS

230       semanage fcontext can also be used to manipulate default  file  context
231       mappings.
232
233       semanage  permissive  can  also  be used to manipulate whether or not a
234       process type is permissive.
235
236       semanage module can also be used to enable/disable/install/remove  pol‐
237       icy modules.
238
239       semanage boolean can also be used to manipulate the booleans
240
241
242       system-config-selinux is a GUI tool available to customize SELinux pol‐
243       icy settings.
