6 uucpd_selinux - Security Enhanced Linux Policy for the uucpd processes
7
9 Security-Enhanced Linux secures the uucpd processes via flexible manda‐
10 tory access control.
11
12 The uucpd processes execute with the uucpd_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 uucpd_t
19
20
21
23 The uucpd_t SELinux type can be entered via the uucpd_exec_t file type.
24
25 The default entrypoint paths for the uucpd_t domain are the following:
26
27 /usr/sbin/uucico
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 uucpd policy is very flexible allowing users to setup their uucpd pro‐
37 cesses in as secure a method as possible.
38
39 The following process types are defined for uucpd:
40
41 uucpd_t
42
43 Note: semanage permissive -a uucpd_t can be used to make the process
44 type uucpd_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. uucpd
51 policy is extremely flexible and has several booleans that allow you to
52 manipulate the policy and run uucpd with the tightest access possible.
53
54
55
56 If you want to dontaudit all daemons scheduling requests (setsched,
57 sys_nice), you must turn on the daemons_dontaudit_scheduling boolean.
58 Enabled by default.
59
60 setsebool -P daemons_dontaudit_scheduling 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 system to run with NIS, you must turn on the
72 nis_enabled boolean. Disabled by default.
73
74 setsebool -P nis_enabled 1
75
76
77
79 SELinux defines port types to represent TCP and UDP ports.
80
81 You can see the types associated with a port by using the following
82 command:
83
84 semanage port -l
85
86
87 Policy governs the access confined processes have to these ports.
88 SELinux uucpd policy is very flexible allowing users to setup their
89 uucpd processes in as secure a method as possible.
90
91 The following port types are defined for uucpd:
92
93
94 uucpd_port_t
95
96
97
98 Default Defined Ports:
99 tcp 540
100
102 The SELinux process type uucpd_t can manage files labeled with the fol‐
103 lowing file types. The paths listed are the default paths for these
104 file types. Note the processes UID still need to have DAC permissions.

176 SELinux requires files to have an extended attribute to define the file
177 type.
178
179 You can see the context of a file using the -Z option to ls
180
181 Policy governs the access confined processes have to these files.
182 SELinux uucpd policy is very flexible allowing users to setup their
183 uucpd processes in as secure a method as possible.
184
185 EQUIVALENCE DIRECTORIES
186
187
188 uucpd policy stores data with multiple different file context types un‐
189 der the /var/spool/uucp directory. If you would like to store the data
190 in a different directory you can use the semanage command to create an
191 equivalence mapping. If you wanted to store this data under the /srv
192 directory you would execute the following command:
193
194 semanage fcontext -a -e /var/spool/uucp /srv/uucp
195 restorecon -R -v /srv/uucp
196
197 STANDARD FILE CONTEXT
198
199 SELinux defines the file context types for the uucpd, if you wanted to
200 store files with these types in a different paths, you need to execute
201 the semanage command to specify alternate labeling and then use re‐
202 storecon to put the labels on disk.
203
204 semanage fcontext -a -t uucpd_exec_t '/srv/uucpd/content(/.*)?'
205 restorecon -R -v /srv/myuucpd_content
206
207 Note: SELinux often uses regular expressions to specify labels that
208 match multiple files.
209
210 The following file types are defined for uucpd:
211
212
213
214 uucpd_exec_t
215
216 - Set files with the uucpd_exec_t type, if you want to transition an
217 executable to the uucpd_t domain.
218
219
220
221 uucpd_initrc_exec_t
222
223 - Set files with the uucpd_initrc_exec_t type, if you want to transi‐
224 tion an executable to the uucpd_initrc_t domain.
225
226
227
228 uucpd_lock_t
229
230 - Set files with the uucpd_lock_t type, if you want to treat the files
231 as uucpd lock data, stored under the /var/lock directory
232
233
234
235 uucpd_log_t
236
237 - Set files with the uucpd_log_t type, if you want to treat the data as
238 uucpd log data, usually stored under the /var/log directory.
239
240
241
242 uucpd_ro_t
243
244 - Set files with the uucpd_ro_t type, if you want to treat the files as
245 uucpd read/only content.
246
247
248
249 uucpd_rw_t
250
251 - Set files with the uucpd_rw_t type, if you want to treat the files as
252 uucpd read/write content.
253
254
255
256 uucpd_spool_t
257
258 - Set files with the uucpd_spool_t type, if you want to store the uucpd
259 files under the /var/spool directory.
260
261
262 Paths:
263 /var/spool/uucp(/.*)?, /var/spool/uucppublic(/.*)?
264
265
266 uucpd_tmp_t
267
268 - Set files with the uucpd_tmp_t type, if you want to store uucpd tem‐
269 porary files in the /tmp directories.
270
271
272
273 uucpd_var_run_t
274
275 - Set files with the uucpd_var_run_t type, if you want to store the
276 uucpd files under the /run or /var/run directory.
277
278
279
280 Note: File context can be temporarily modified with the chcon command.
281 If you want to permanently change the file context you need to use the
282 semanage fcontext command. This will modify the SELinux labeling data‐
283 base. You will need to use restorecon to apply the labels.
284
285
287 semanage fcontext can also be used to manipulate default file context
288 mappings.
289
290 semanage permissive can also be used to manipulate whether or not a
291 process type is permissive.
292
293 semanage module can also be used to enable/disable/install/remove pol‐
294 icy modules.
295
296 semanage port can also be used to manipulate the port definitions
297
298 semanage boolean can also be used to manipulate the booleans
299

301 system-config-selinux is a GUI tool available to customize SELinux pol‐
302 icy settings.
