6 lwregd_selinux - Security Enhanced Linux Policy for the lwregd pro‐
7 cesses
8
10 Security-Enhanced Linux secures the lwregd processes via flexible
11 mandatory access control.
12
13 The lwregd processes execute with the lwregd_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 lwregd_t
20
21
22
24 The lwregd_t SELinux type can be entered via the lwregd_exec_t file
25 type.
26
27 The default entrypoint paths for the lwregd_t domain are the following:
28
29 /usr/sbin/lwregd, /opt/likewise/sbin/lwregd
30
32 SELinux defines process types (domains) for each process running on the
33 system
34
35 You can see the context of a process using the -Z option to ps
36
37 Policy governs the access confined processes have to files. SELinux
38 lwregd policy is very flexible allowing users to setup their lwregd
39 processes in as secure a method as possible.
40
41 The following process types are defined for lwregd:
42
43 lwregd_t
44
45 Note: semanage permissive -a lwregd_t can be used to make the process
46 type lwregd_t permissive. SELinux does not deny access to permissive
47 process types, but the AVC (SELinux denials) messages are still gener‐
48 ated.
49
50
52 SELinux policy is customizable based on least access required. lwregd
53 policy is extremely flexible and has several booleans that allow you to
54 manipulate the policy and run lwregd with the tightest access possible.

140 The SELinux process type lwregd_t can manage files labeled with the
141 following file types. The paths listed are the default paths for these
142 file types. Note the processes UID still need to have DAC permissions.

192 SELinux requires files to have an extended attribute to define the file
193 type.
194
195 You can see the context of a file using the -Z option to ls
196
197 Policy governs the access confined processes have to these files.
198 SELinux lwregd policy is very flexible allowing users to setup their
199 lwregd processes in as secure a method as possible.
200
201 STANDARD FILE CONTEXT
202
203 SELinux defines the file context types for the lwregd, if you wanted to
204 store files with these types in a diffent paths, you need to execute
205 the semanage command to sepecify alternate labeling and then use
206 restorecon to put the labels on disk.
207
208 semanage fcontext -a -t lwregd_var_socket_t '/srv/mylwregd_con‐
209 tent(/.*)?'
210 restorecon -R -v /srv/mylwregd_content
211
212 Note: SELinux often uses regular expressions to specify labels that
213 match multiple files.
214
215 The following file types are defined for lwregd:
216
217
218
219 lwregd_exec_t
220
221 - Set files with the lwregd_exec_t type, if you want to transition an
222 executable to the lwregd_t domain.
223
224
225 Paths:
226 /usr/sbin/lwregd, /opt/likewise/sbin/lwregd
227
228
229 lwregd_var_lib_t
230
231 - Set files with the lwregd_var_lib_t type, if you want to store the
232 lwregd files under the /var/lib directory.
233
234
235 Paths:
236 /var/lib/likewise/regsd.err, /var/lib/likewise/db/registry.db,
237 /var/lib/likewise-open/regsd.err, /var/lib/likewise-open/db/reg‐
238 istry.db
239
240
241 lwregd_var_run_t
242
243 - Set files with the lwregd_var_run_t type, if you want to store the
244 lwregd files under the /run or /var/run directory.
245
246
247
248 lwregd_var_socket_t
249
250 - Set files with the lwregd_var_socket_t type, if you want to treat the
251 files as lwregd var socket data.
252
253
254 Paths:
255 /var/lib/likewise/.regsd, /var/lib/likewise-open/.regsd
256
257
258 Note: File context can be temporarily modified with the chcon command.
259 If you want to permanently change the file context you need to use the
260 semanage fcontext command. This will modify the SELinux labeling data‐
261 base. You will need to use restorecon to apply the labels.
262
263
265 semanage fcontext can also be used to manipulate default file context
266 mappings.
267
268 semanage permissive can also be used to manipulate whether or not a
269 process type is permissive.
270
271 semanage module can also be used to enable/disable/install/remove pol‐
272 icy modules.
273
274 semanage boolean can also be used to manipulate the booleans
275
276
277 system-config-selinux is a GUI tool available to customize SELinux pol‐
278 icy settings.
