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 users to resolve user passwd entries directly from
68       ldap rather then using a sssd server, you  must  turn  on  the  authlo‐
69       gin_nsswitch_use_ldap boolean. Disabled by default.
70
71       setsebool -P authlogin_nsswitch_use_ldap 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 confined applications to run  with  kerberos,  you
83       must turn on the kerberos_enabled boolean. Disabled by default.
84
85       setsebool -P kerberos_enabled 1
86
87
88
89       If  you  want  to  allow  system  to run with NIS, you must turn on the
90       nis_enabled boolean. Disabled by default.
91
92       setsebool -P nis_enabled 1
93
94
95
96       If you want to allow confined applications to use nscd  shared  memory,
97       you must turn on the nscd_use_shm boolean. Disabled by default.
98
99       setsebool -P nscd_use_shm 1

MANAGED FILES

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

FILE CONTEXTS

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

COMMANDS

315       semanage fcontext can also be used to manipulate default  file  context
316       mappings.
317
318       semanage  permissive  can  also  be used to manipulate whether or not a
319       process type is permissive.
320
321       semanage module can also be used to enable/disable/install/remove  pol‐
322       icy modules.
323
324       semanage boolean can also be used to manipulate the booleans
325
326
327       system-config-selinux is a GUI tool available to customize SELinux pol‐
328       icy settings.
