6 sanlock_selinux - Security Enhanced Linux Policy for the sanlock pro‐
7 cesses
8
10 Security-Enhanced Linux secures the sanlock processes via flexible
11 mandatory access control.
12
13 The sanlock processes execute with the sanlock_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 sanlock_t
20
21
22
24 The sanlock_t SELinux type can be entered via the sanlock_exec_t file
25 type.
26
27 The default entrypoint paths for the sanlock_t domain are the follow‐
28 ing:
29
30 /usr/sbin/sanlock
31
33 SELinux defines process types (domains) for each process running on the
34 system
35
36 You can see the context of a process using the -Z option to ps
37
38 Policy governs the access confined processes have to files. SELinux
39 sanlock policy is very flexible allowing users to setup their sanlock
40 processes in as secure a method as possible.
41
42 The following process types are defined for sanlock:
43
44 sanlock_t
45
46 Note: semanage permissive -a sanlock_t can be used to make the process
47 type sanlock_t permissive. SELinux does not deny access to permissive
48 process types, but the AVC (SELinux denials) messages are still gener‐
49 ated.
50
51
53 SELinux policy is customizable based on least access required. sanlock
54 policy is extremely flexible and has several booleans that allow you to
55 manipulate the policy and run sanlock with the tightest access possi‐
56 ble.
57

59
60 If you want to allow sanlock to read/write user home directories, you
61 must turn on the sanlock_enable_home_dirs boolean. Disabled by default.

105
106 setsebool -P kerberos_enabled 1
107
108
109
110 If you want to allow system to run with NIS, you must turn on the

119

121
122
123
125 The SELinux process type sanlock_t can manage files labeled with the
126 following file types. The paths listed are the default paths for these
127 file types. Note the processes UID still need to have DAC permissions.

205 SELinux requires files to have an extended attribute to define the file
206 type.
207
208 You can see the context of a file using the -Z option to ls
209
210 Policy governs the access confined processes have to these files.
211 SELinux sanlock policy is very flexible allowing users to setup their
212 sanlock processes in as secure a method as possible.
213
214 STANDARD FILE CONTEXT
215
216 SELinux defines the file context types for the sanlock, if you wanted
217 to store files with these types in a diffent paths, you need to execute
218 the semanage command to sepecify alternate labeling and then use
219 restorecon to put the labels on disk.
220
221 semanage fcontext -a -t sanlock_unit_file_t '/srv/mysanlock_con‐
222 tent(/.*)?'
223 restorecon -R -v /srv/mysanlock_content
224
225 Note: SELinux often uses regular expressions to specify labels that
226 match multiple files.
227
228 The following file types are defined for sanlock:
229
230
231
232 sanlock_conf_t
233
234 - Set files with the sanlock_conf_t type, if you want to treat the
235 files as sanlock configuration data, usually stored under the /etc
236 directory.
237
238
239
240 sanlock_exec_t
241
242 - Set files with the sanlock_exec_t type, if you want to transition an
243 executable to the sanlock_t domain.
244
245
246
247 sanlock_initrc_exec_t
248
249 - Set files with the sanlock_initrc_exec_t type, if you want to transi‐
250 tion an executable to the sanlock_initrc_t domain.
251
252
253
254 sanlock_log_t
255
256 - Set files with the sanlock_log_t type, if you want to treat the data
257 as sanlock log data, usually stored under the /var/log directory.
258
259
260
261 sanlock_unit_file_t
262
263 - Set files with the sanlock_unit_file_t type, if you want to treat the
264 files as sanlock unit content.
265
266
267
268 sanlock_var_run_t
269
270 - Set files with the sanlock_var_run_t type, if you want to store the
271 sanlock files under the /run or /var/run directory.
272
273
274 Paths:
275 /var/run/sanlock(/.*)?, /var/run/sanlk-resetd(/.*)?
276
277
278 Note: File context can be temporarily modified with the chcon command.
279 If you want to permanently change the file context you need to use the
280 semanage fcontext command. This will modify the SELinux labeling data‐
281 base. You will need to use restorecon to apply the labels.
282
283
285 semanage fcontext can also be used to manipulate default file context
286 mappings.
287
288 semanage permissive can also be used to manipulate whether or not a
289 process type is permissive.
290
291 semanage module can also be used to enable/disable/install/remove pol‐
292 icy modules.
293
294 semanage boolean can also be used to manipulate the booleans
295
296
297 system-config-selinux is a GUI tool available to customize SELinux pol‐
298 icy settings.
