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.
53
54
55
56 If you want to allow users to resolve user passwd entries directly from
57 ldap rather then using a sssd server, you must turn on the authlo‐
58 gin_nsswitch_use_ldap boolean. Disabled by default.
59
60 setsebool -P authlogin_nsswitch_use_ldap 1
61
62
63
64 If you want to allow all domains to execute in fips_mode, you must turn
65 on the fips_mode boolean. Enabled by default.
66
67 setsebool -P fips_mode 1
68
69
70
71 If you want to allow confined applications to run with kerberos, you
72 must turn on the kerberos_enabled boolean. Enabled by default.
73
74 setsebool -P kerberos_enabled 1
75
76
77
78 If you want to allow system to run with NIS, you must turn on the
79 nis_enabled boolean. Disabled by default.
80
81 setsebool -P nis_enabled 1
82
83
84
85 If you want to allow confined applications to use nscd shared memory,
86 you must turn on the nscd_use_shm boolean. Enabled by default.
87
88 setsebool -P nscd_use_shm 1
89

91
93 SELinux defines port types to represent TCP and UDP ports.
94
95 You can see the types associated with a port by using the following
96 command:
97
98 semanage port -l
99
100
101 Policy governs the access confined processes have to these ports.
102 SELinux lircd policy is very flexible allowing users to setup their
103 lircd processes in as secure a method as possible.
104
105 The following port types are defined for lircd:
106
107
108 lirc_port_t
109
110
111
112 Default Defined Ports:
113 tcp 8765
114
116 The SELinux process type lircd_t can manage files labeled with the fol‐
117 lowing file types. The paths listed are the default paths for these
118 file types. Note the processes UID still need to have DAC permissions.

174 SELinux requires files to have an extended attribute to define the file
175 type.
176
177 You can see the context of a file using the -Z option to ls
178
179 Policy governs the access confined processes have to these files.
180 SELinux lircd policy is very flexible allowing users to setup their
181 lircd processes in as secure a method as possible.
182
183 EQUIVALENCE DIRECTORIES
184
185
186 lircd policy stores data with multiple different file context types
187 under the /var/run/lirc directory. If you would like to store the data
188 in a different directory you can use the semanage command to create an
189 equivalence mapping. If you wanted to store this data under the /srv
190 dirctory you would execute the following command:
191
192 semanage fcontext -a -e /var/run/lirc /srv/lirc
193 restorecon -R -v /srv/lirc
194
195 STANDARD FILE CONTEXT
196
197 SELinux defines the file context types for the lircd, if you wanted to
198 store files with these types in a diffent paths, you need to execute
199 the semanage command to sepecify alternate labeling and then use
200 restorecon to put the labels on disk.
201
202 semanage fcontext -a -t lircd_var_run_t '/srv/mylircd_content(/.*)?'
203 restorecon -R -v /srv/mylircd_content
204
205 Note: SELinux often uses regular expressions to specify labels that
206 match multiple files.
207
208 The following file types are defined for lircd:
209
210
211
212 lircd_etc_t
213
214 - Set files with the lircd_etc_t type, if you want to store lircd files
215 in the /etc directories.
216
217
218 Paths:
219 /etc/lirc(/.*)?, /etc/lircd.conf
220
221
222 lircd_exec_t
223
224 - Set files with the lircd_exec_t type, if you want to transition an
225 executable to the lircd_t domain.
226
227
228
229 lircd_initrc_exec_t
230
231 - Set files with the lircd_initrc_exec_t type, if you want to transi‐
232 tion an executable to the lircd_initrc_t domain.
233
234
235
236 lircd_var_run_t
237
238 - Set files with the lircd_var_run_t type, if you want to store the
239 lircd files under the /run or /var/run directory.
240
241
242 Paths:
243 /var/run/lirc(/.*)?, /var/run/lircd(/.*)?, /dev/lircd,
244 /var/run/lircd.pid
245
246
247 Note: File context can be temporarily modified with the chcon command.
248 If you want to permanently change the file context you need to use the
249 semanage fcontext command. This will modify the SELinux labeling data‐
250 base. You will need to use restorecon to apply the labels.
251
252
254 semanage fcontext can also be used to manipulate default file context
255 mappings.
256
257 semanage permissive can also be used to manipulate whether or not a
258 process type is permissive.
259
260 semanage module can also be used to enable/disable/install/remove pol‐
261 icy modules.
262
263 semanage port can also be used to manipulate the port definitions
264
265 semanage boolean can also be used to manipulate the booleans
266
267
268 system-config-selinux is a GUI tool available to customize SELinux pol‐
269 icy settings.
