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

127
129 The SELinux process type tgtd_t can manage files labeled with the fol‐
130 lowing file types. The paths listed are the default paths for these
131 file types. Note the processes UID still need to have DAC permissions.

203 SELinux requires files to have an extended attribute to define the file
204 type.
205
206 You can see the context of a file using the -Z option to ls
207
208 Policy governs the access confined processes have to these files.
209 SELinux tgtd policy is very flexible allowing users to setup their tgtd
210 processes in as secure a method as possible.
211
212 STANDARD FILE CONTEXT
213
214 SELinux defines the file context types for the tgtd, if you wanted to
215 store files with these types in a diffent paths, you need to execute
216 the semanage command to sepecify alternate labeling and then use
217 restorecon to put the labels on disk.
218
219 semanage fcontext -a -t tgtd_var_run_t '/srv/mytgtd_content(/.*)?'
220 restorecon -R -v /srv/mytgtd_content
221
222 Note: SELinux often uses regular expressions to specify labels that
223 match multiple files.
224
225 The following file types are defined for tgtd:
226
227
228
229 tgtd_exec_t
230
231 - Set files with the tgtd_exec_t type, if you want to transition an
232 executable to the tgtd_t domain.
233
234
235
236 tgtd_initrc_exec_t
237
238 - Set files with the tgtd_initrc_exec_t type, if you want to transition
239 an executable to the tgtd_initrc_t domain.
240
241
242
243 tgtd_tmp_t
244
245 - Set files with the tgtd_tmp_t type, if you want to store tgtd tempo‐
246 rary files in the /tmp directories.
247
248
249
250 tgtd_tmpfs_t
251
252 - Set files with the tgtd_tmpfs_t type, if you want to store tgtd files
253 on a tmpfs file system.
254
255
256
257 tgtd_var_lib_t
258
259 - Set files with the tgtd_var_lib_t type, if you want to store the tgtd
260 files under the /var/lib directory.
261
262
263
264 tgtd_var_run_t
265
266 - Set files with the tgtd_var_run_t type, if you want to store the tgtd
267 files under the /run or /var/run directory.
268
269
270
271 Note: File context can be temporarily modified with the chcon command.
272 If you want to permanently change the file context you need to use the
273 semanage fcontext command. This will modify the SELinux labeling data‐
274 base. You will need to use restorecon to apply the labels.
275
276
278 semanage fcontext can also be used to manipulate default file context
279 mappings.
280
281 semanage permissive can also be used to manipulate whether or not a
282 process type is permissive.
283
284 semanage module can also be used to enable/disable/install/remove pol‐
285 icy modules.
286
287 semanage boolean can also be used to manipulate the booleans
288
289
290 system-config-selinux is a GUI tool available to customize SELinux pol‐
291 icy settings.
