6 l2tpd_selinux - Security Enhanced Linux Policy for the l2tpd processes
7
9 Security-Enhanced Linux secures the l2tpd processes via flexible manda‐
10 tory access control.
11
12 The l2tpd processes execute with the l2tpd_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 l2tpd_t
19
20
21
23 The l2tpd_t SELinux type can be entered via the l2tpd_exec_t file type.
24
25 The default entrypoint paths for the l2tpd_t domain are the following:
26
27 /usr/sbin/.*l2tpd, /usr/libexec/nm-l2tp-service
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 l2tpd policy is very flexible allowing users to setup their l2tpd pro‐
37 cesses in as secure a method as possible.
38
39 The following process types are defined for l2tpd:
40
41 l2tpd_t
42
43 Note: semanage permissive -a l2tpd_t can be used to make the process
44 type l2tpd_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. l2tpd
51 policy is extremely flexible and has several booleans that allow you to
52 manipulate the policy and run l2tpd with the tightest access possible.

141
142

145 SELinux defines port types to represent TCP and UDP ports.
146
147 You can see the types associated with a port by using the following
148 command:
149
150 semanage port -l
151
152
153 Policy governs the access confined processes have to these ports.
154 SELinux l2tpd policy is very flexible allowing users to setup their
155 l2tpd processes in as secure a method as possible.
156
157 The following port types are defined for l2tpd:
158
159
160 l2tp_port_t
161
162
163
164 Default Defined Ports:
165 tcp 1701
166 udp 1701
167
169 The SELinux process type l2tpd_t can manage files labeled with the fol‐
170 lowing file types. The paths listed are the default paths for these
171 file types. Note the processes UID still need to have DAC permissions.

238 SELinux requires files to have an extended attribute to define the file
239 type.
240
241 You can see the context of a file using the -Z option to ls
242
243 Policy governs the access confined processes have to these files.
244 SELinux l2tpd policy is very flexible allowing users to setup their
245 l2tpd processes in as secure a method as possible.
246
247 EQUIVALENCE DIRECTORIES
248
249
250 l2tpd policy stores data with multiple different file context types
251 under the /var/run/.*l2tpd directory. If you would like to store the
252 data in a different directory you can use the semanage command to cre‐
253 ate an equivalence mapping. If you wanted to store this data under the
254 /srv dirctory you would execute the following command:
255
256 semanage fcontext -a -e /var/run/.*l2tpd /srv/.*l2tpd
257 restorecon -R -v /srv/.*l2tpd
258
259 STANDARD FILE CONTEXT
260
261 SELinux defines the file context types for the l2tpd, if you wanted to
262 store files with these types in a diffent paths, you need to execute
263 the semanage command to sepecify alternate labeling and then use
264 restorecon to put the labels on disk.
265
266 semanage fcontext -a -t l2tpd_var_run_t '/srv/myl2tpd_content(/.*)?'
267 restorecon -R -v /srv/myl2tpd_content
268
269 Note: SELinux often uses regular expressions to specify labels that
270 match multiple files.
271
272 The following file types are defined for l2tpd:
273
274
275
276 l2tpd_exec_t
277
278 - Set files with the l2tpd_exec_t type, if you want to transition an
279 executable to the l2tpd_t domain.
280
281
282 Paths:
283 /usr/sbin/.*l2tpd, /usr/libexec/nm-l2tp-service
284
285
286 l2tpd_initrc_exec_t
287
288 - Set files with the l2tpd_initrc_exec_t type, if you want to transi‐
289 tion an executable to the l2tpd_initrc_t domain.
290
291
292
293 l2tpd_tmp_t
294
295 - Set files with the l2tpd_tmp_t type, if you want to store l2tpd tem‐
296 porary files in the /tmp directories.
297
298
299
300 l2tpd_var_run_t
301
302 - Set files with the l2tpd_var_run_t type, if you want to store the
303 l2tpd files under the /run or /var/run directory.
304
305
306 Paths:
307 /var/run/*.xl2tpd.*, /var/run/.*l2tpd.pid, /var/run/.*l2tpd(/.*)?,
308 /var/run/prol2tpd.ctl
309
310
311 Note: File context can be temporarily modified with the chcon command.
312 If you want to permanently change the file context you need to use the
313 semanage fcontext command. This will modify the SELinux labeling data‐
314 base. You will need to use restorecon to apply the labels.
315
316
318 semanage fcontext can also be used to manipulate default file context
319 mappings.
320
321 semanage permissive can also be used to manipulate whether or not a
322 process type is permissive.
323
324 semanage module can also be used to enable/disable/install/remove pol‐
325 icy modules.
326
327 semanage port can also be used to manipulate the port definitions
328
329 semanage boolean can also be used to manipulate the booleans
330
331
332 system-config-selinux is a GUI tool available to customize SELinux pol‐
333 icy settings.
