6 dnsmasq_selinux - Security Enhanced Linux Policy for the dnsmasq pro‐
7 cesses
8
10 Security-Enhanced Linux secures the dnsmasq processes via flexible
11 mandatory access control.
12
13 The dnsmasq processes execute with the dnsmasq_t SELinux type. You can
14 check if you have these processes running by executing the ps command
15 with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep dnsmasq_t
20
21
22
24 The dnsmasq_t SELinux type can be entered via the dnsmasq_exec_t file
25 type.
26
27 The default entrypoint paths for the dnsmasq_t domain are the follow‐
28 ing:
29
30 /usr/sbin/dnsmasq
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 dnsmasq policy is very flexible allowing users to setup their dnsmasq
40 processes in as secure a method as possible.
41
42 The following process types are defined for dnsmasq:
43
44 dnsmasq_t
45
46 Note: semanage permissive -a dnsmasq_t can be used to make the process
47 type dnsmasq_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. dnsmasq
54 policy is extremely flexible and has several booleans that allow you to
55 manipulate the policy and run dnsmasq with the tightest access possi‐
56 ble.
57
58
59
60 If you want to allow the dnsmasq to creating and using netlink_sockets,
61 you must turn on the dnsmasq_use_ipset boolean. Disabled by default.
62
63 setsebool -P dnsmasq_use_ipset 1
64
65
66
67 If you want to dontaudit all daemons scheduling requests (setsched,
68 sys_nice), you must turn on the daemons_dontaudit_scheduling boolean.
69 Enabled by default.
70
71 setsebool -P daemons_dontaudit_scheduling 1
72
73
74
75 If you want to allow all domains to execute in fips_mode, you must turn
76 on the fips_mode boolean. Enabled by default.
77
78 setsebool -P fips_mode 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

90 The SELinux process type dnsmasq_t can manage files labeled with the
91 following file types. The paths listed are the default paths for these
92 file types. Note the processes UID still need to have DAC permissions.

212 SELinux requires files to have an extended attribute to define the file
213 type.
214
215 You can see the context of a file using the -Z option to ls
216
217 Policy governs the access confined processes have to these files.
218 SELinux dnsmasq policy is very flexible allowing users to setup their
219 dnsmasq processes in as secure a method as possible.
220
221 STANDARD FILE CONTEXT
222
223 SELinux defines the file context types for the dnsmasq, if you wanted
224 to store files with these types in a different paths, you need to exe‐
225 cute the semanage command to specify alternate labeling and then use
226 restorecon to put the labels on disk.
227
228 semanage fcontext -a -t dnsmasq_exec_t '/srv/dnsmasq/content(/.*)?'
229 restorecon -R -v /srv/mydnsmasq_content
230
231 Note: SELinux often uses regular expressions to specify labels that
232 match multiple files.
233
234 The following file types are defined for dnsmasq:
235
236
237
238 dnsmasq_etc_t
239
240 - Set files with the dnsmasq_etc_t type, if you want to store dnsmasq
241 files in the /etc directories.
242
243
244 Paths:
245 /etc/dnsmasq.d(/.*)?, /etc/dnsmasq.conf
246
247
248 dnsmasq_exec_t
249
250 - Set files with the dnsmasq_exec_t type, if you want to transition an
251 executable to the dnsmasq_t domain.
252
253
254
255 dnsmasq_initrc_exec_t
256
257 - Set files with the dnsmasq_initrc_exec_t type, if you want to transi‐
258 tion an executable to the dnsmasq_initrc_t domain.
259
260
261
262 dnsmasq_lease_t
263
264 - Set files with the dnsmasq_lease_t type, if you want to treat the
265 files as dnsmasq lease data.
266
267
268 Paths:
269 /var/lib/dnsmasq(/.*)?, /var/lib/misc/dnsmasq.leases
270
271
272 dnsmasq_tmp_t
273
274 - Set files with the dnsmasq_tmp_t type, if you want to store dnsmasq
275 temporary files in the /tmp directories.
276
277
278
279 dnsmasq_unit_file_t
280
281 - Set files with the dnsmasq_unit_file_t type, if you want to treat the
282 files as dnsmasq unit content.
283
284
285
286 dnsmasq_var_log_t
287
288 - Set files with the dnsmasq_var_log_t type, if you want to treat the
289 data as dnsmasq var log data, usually stored under the /var/log direc‐
290 tory.
291
292
293
294 dnsmasq_var_run_t
295
296 - Set files with the dnsmasq_var_run_t type, if you want to store the
297 dnsmasq files under the /run or /var/run directory.
298
299
300 Paths:
301 /var/run/dnsmasq.*, /var/run/libvirt/network(/.*)?
302
303
304 Note: File context can be temporarily modified with the chcon command.
305 If you want to permanently change the file context you need to use the
306 semanage fcontext command. This will modify the SELinux labeling data‐
307 base. You will need to use restorecon to apply the labels.
308
309
311 semanage fcontext can also be used to manipulate default file context
312 mappings.
313
314 semanage permissive can also be used to manipulate whether or not a
315 process type is permissive.
316
317 semanage module can also be used to enable/disable/install/remove pol‐
318 icy modules.
319
320 semanage boolean can also be used to manipulate the booleans
321
322
323 system-config-selinux is a GUI tool available to customize SELinux pol‐
324 icy settings.
