NAME

6       dnsmasq_selinux  -  Security Enhanced Linux Policy for the dnsmasq pro‐
7       cesses
8

DESCRIPTION

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

ENTRYPOINTS

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

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       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

BOOLEANS

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 allow all domains to execute in fips_mode, you must turn
68       on the fips_mode boolean. Enabled by default.
69
70       setsebool -P fips_mode 1
71
72
73

MANAGED FILES

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

FILE CONTEXTS

179       SELinux requires files to have an extended attribute to define the file
180       type.
181
182       You can see the context of a file using the -Z option to ls
183
184       Policy  governs  the  access  confined  processes  have to these files.
185       SELinux dnsmasq policy is very flexible allowing users to  setup  their
186       dnsmasq processes in as secure a method as possible.
187
188       STANDARD FILE CONTEXT
189
190       SELinux  defines  the file context types for the dnsmasq, if you wanted
191       to store files with these types in a diffent paths, you need to execute
192       the  semanage  command  to  sepecify  alternate  labeling  and then use
193       restorecon to put the labels on disk.
194
195       semanage fcontext -a -t dnsmasq_tmp_t '/srv/mydnsmasq_content(/.*)?'
196       restorecon -R -v /srv/mydnsmasq_content
197
198       Note: SELinux often uses regular expressions  to  specify  labels  that
199       match multiple files.
200
201       The following file types are defined for dnsmasq:
202
203
204
205       dnsmasq_etc_t
206
207       -  Set  files with the dnsmasq_etc_t type, if you want to store dnsmasq
208       files in the /etc directories.
209
210
211       Paths:
212            /etc/dnsmasq.d(/.*)?, /etc/dnsmasq.conf
213
214
215       dnsmasq_exec_t
216
217       - Set files with the dnsmasq_exec_t type, if you want to transition  an
218       executable to the dnsmasq_t domain.
219
220
221
222       dnsmasq_initrc_exec_t
223
224       - Set files with the dnsmasq_initrc_exec_t type, if you want to transi‐
225       tion an executable to the dnsmasq_initrc_t domain.
226
227
228
229       dnsmasq_lease_t
230
231       - Set files with the dnsmasq_lease_t type, if you  want  to  treat  the
232       files as dnsmasq lease data.
233
234
235       Paths:
236            /var/lib/dnsmasq(/.*)?, /var/lib/misc/dnsmasq.leases
237
238
239       dnsmasq_tmp_t
240
241       -  Set  files with the dnsmasq_tmp_t type, if you want to store dnsmasq
242       temporary files in the /tmp directories.
243
244
245
246       dnsmasq_unit_file_t
247
248       - Set files with the dnsmasq_unit_file_t type, if you want to treat the
249       files as dnsmasq unit content.
250
251
252
253       dnsmasq_var_log_t
254
255       -  Set  files with the dnsmasq_var_log_t type, if you want to treat the
256       data as dnsmasq var log data, usually stored under the /var/log  direc‐
257       tory.
258
259
260
261       dnsmasq_var_run_t
262
263       -  Set  files with the dnsmasq_var_run_t type, if you want to store the
264       dnsmasq files under the /run or /var/run directory.
265
266
267       Paths:
268            /var/run/dnsmasq.*, /var/run/libvirt/network(/.*)?
269
270
271       Note: File context can be temporarily modified with the chcon  command.
272       If  you want to permanently change the file context you need to use the
273       semanage fcontext command.  This will modify the SELinux labeling data‐
274       base.  You will need to use restorecon to apply the labels.
275
276

COMMANDS

278       semanage  fcontext  can also be used to manipulate default file context
279       mappings.
280
281       semanage permissive can also be used to manipulate  whether  or  not  a
282       process type is permissive.
283
284       semanage  module can also be used to enable/disable/install/remove pol‐
285       icy modules.
286
287       semanage boolean can also be used to manipulate the booleans
288
289
290       system-config-selinux is a GUI tool available to customize SELinux pol‐
291       icy settings.
