6 lircd_selinux - Security Enhanced Linux Policy for the lircd processes
7
9 Security-Enhanced Linux secures the lircd processes via flexible manda‐
10 tory access control.
11
12 The lircd processes execute with the lircd_t SELinux type. You can
13 check if you have these processes running by executing the ps command
14 with the -Z qualifier.
15
16 For example:
17
18 ps -eZ | grep lircd_t
19
20
21
23 The lircd_t SELinux type can be entered via the lircd_exec_t file type.
24
25 The default entrypoint paths for the lircd_t domain are the following:
26
27 /usr/sbin/lircd
28
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 lircd policy is very flexible allowing users to setup their lircd pro‐
37 cesses in as secure a method as possible.
38
39 The following process types are defined for lircd:
40
41 lircd_t
42
43 Note: semanage permissive -a lircd_t can be used to make the process
44 type lircd_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
50 SELinux policy is customizable based on least access required. lircd
51 policy is extremely flexible and has several booleans that allow you to
52 manipulate the policy and run lircd with the tightest access possible.

167 SELinux defines port types to represent TCP and UDP ports.
168
169 You can see the types associated with a port by using the following
170 command:
171
172 semanage port -l
173
174
175 Policy governs the access confined processes have to these ports.
176 SELinux lircd policy is very flexible allowing users to setup their
177 lircd processes in as secure a method as possible.
178
179 The following port types are defined for lircd:
180
181
182 lirc_port_t
183
184
185
186 Default Defined Ports:
187 tcp 8765
188
190 The SELinux process type lircd_t can manage files labeled with the fol‐
191 lowing file types. The paths listed are the default paths for these
192 file types. Note the processes UID still need to have DAC permissions.

244 SELinux requires files to have an extended attribute to define the file
245 type.
246
247 You can see the context of a file using the -Z option to ls
248
249 Policy governs the access confined processes have to these files.
250 SELinux lircd policy is very flexible allowing users to setup their
251 lircd processes in as secure a method as possible.
252
253 EQUIVALENCE DIRECTORIES
254
255
256 lircd policy stores data with multiple different file context types
257 under the /var/run/lirc directory. If you would like to store the data
258 in a different directory you can use the semanage command to create an
259 equivalence mapping. If you wanted to store this data under the /srv
260 dirctory you would execute the following command:
261
262 semanage fcontext -a -e /var/run/lirc /srv/lirc
263 restorecon -R -v /srv/lirc
264
265 STANDARD FILE CONTEXT
266
267 SELinux defines the file context types for the lircd, if you wanted to
268 store files with these types in a diffent paths, you need to execute
269 the semanage command to sepecify alternate labeling and then use
270 restorecon to put the labels on disk.
271
272 semanage fcontext -a -t lircd_var_run_t '/srv/mylircd_content(/.*)?'
273 restorecon -R -v /srv/mylircd_content
274
275 Note: SELinux often uses regular expressions to specify labels that
276 match multiple files.
277
278 The following file types are defined for lircd:
279
280
281
282 lircd_etc_t
283
284 - Set files with the lircd_etc_t type, if you want to store lircd files
285 in the /etc directories.
286
287
288 Paths:
289 /etc/lirc(/.*)?, /etc/lircd.conf
290
291
292 lircd_exec_t
293
294 - Set files with the lircd_exec_t type, if you want to transition an
295 executable to the lircd_t domain.
296
297
298
299 lircd_initrc_exec_t
300
301 - Set files with the lircd_initrc_exec_t type, if you want to transi‐
302 tion an executable to the lircd_initrc_t domain.
303
304
305
306 lircd_var_run_t
307
308 - Set files with the lircd_var_run_t type, if you want to store the
309 lircd files under the /run or /var/run directory.
310
311
312 Paths:
313 /var/run/lirc(/.*)?, /var/run/lircd(/.*)?, /dev/lircd,
314 /var/run/lircd.pid
315
316
317 Note: File context can be temporarily modified with the chcon command.
318 If you want to permanently change the file context you need to use the
319 semanage fcontext command. This will modify the SELinux labeling data‐
320 base. You will need to use restorecon to apply the labels.
321
322
324 semanage fcontext can also be used to manipulate default file context
325 mappings.
326
327 semanage permissive can also be used to manipulate whether or not a
328 process type is permissive.
329
330 semanage module can also be used to enable/disable/install/remove pol‐
331 icy modules.
332
333 semanage port can also be used to manipulate the port definitions
334
335 semanage boolean can also be used to manipulate the booleans
336
337
338 system-config-selinux is a GUI tool available to customize SELinux pol‐
339 icy settings.
