6 winbind_selinux - Security Enhanced Linux Policy for the winbind pro‐
7 cesses
8
10 Security-Enhanced Linux secures the winbind processes via flexible
11 mandatory access control.
12
13 The winbind processes execute with the winbind_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 winbind_t
20
21
22
24 The winbind_t SELinux type can be entered via the winbind_exec_t file
25 type.
26
27 The default entrypoint paths for the winbind_t domain are the follow‐
28 ing:
29
30 /usr/sbin/winbindd
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 winbind policy is very flexible allowing users to setup their winbind
40 processes in as secure a method as possible.
41
42 The following process types are defined for winbind:
43
44 winbind_t, winbind_helper_t, winbind_rpcd_t
45
46 Note: semanage permissive -a winbind_t can be used to make the process
47 type winbind_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. winbind
54 policy is extremely flexible and has several booleans that allow you to
55 manipulate the policy and run winbind with the tightest access possi‐
56 ble.

60 If you want to dontaudit all daemons scheduling requests (setsched,
61 sys_nice), you must turn on the daemons_dontaudit_scheduling boolean.
62 Enabled by default.
63
64 setsebool -P daemons_dontaudit_scheduling 1
65
66
67
68 If you want to allow all domains to execute in fips_mode, you must turn
69 on the fips_mode boolean. Enabled by default.
70
71 setsebool -P fips_mode 1
72
73
74
75 If you want to allow system to run with NIS, you must turn on the
76 nis_enabled boolean. Disabled by default.
77
78 setsebool -P nis_enabled 1
79

81
83 The SELinux process type winbind_t can manage files labeled with the
84 following file types. The paths listed are the default paths for these
85 file types. Note the processes UID still need to have DAC permissions.

217 SELinux requires files to have an extended attribute to define the file
218 type.
219
220 You can see the context of a file using the -Z option to ls
221
222 Policy governs the access confined processes have to these files.
223 SELinux winbind policy is very flexible allowing users to setup their
224 winbind processes in as secure a method as possible.
225
226 STANDARD FILE CONTEXT
227
228 SELinux defines the file context types for the winbind, if you wanted
229 to store files with these types in a different paths, you need to exe‐
230 cute the semanage command to specify alternate labeling and then use
231 restorecon to put the labels on disk.
232
233 semanage fcontext -a -t winbind_exec_t '/srv/winbind/content(/.*)?'
234 restorecon -R -v /srv/mywinbind_content
235
236 Note: SELinux often uses regular expressions to specify labels that
237 match multiple files.
238
239 The following file types are defined for winbind:
240
241
242
243 winbind_exec_t
244
245 - Set files with the winbind_exec_t type, if you want to transition an
246 executable to the winbind_t domain.
247
248
249
250 winbind_helper_exec_t
251
252 - Set files with the winbind_helper_exec_t type, if you want to transi‐
253 tion an executable to the winbind_helper_t domain.
254
255
256
257 winbind_log_t
258
259 - Set files with the winbind_log_t type, if you want to treat the data
260 as winbind log data, usually stored under the /var/log directory.
261
262
263
264 winbind_rpcd_exec_t
265
266 - Set files with the winbind_rpcd_exec_t type, if you want to transi‐
267 tion an executable to the winbind_rpcd_t domain.
268
269
270 Paths:
271 /usr/libexec/samba/rpcd_lsad, /usr/libexec/samba/samba-dcerpcd
272
273
274 winbind_rpcd_tmp_t
275
276 - Set files with the winbind_rpcd_tmp_t type, if you want to store win‐
277 bind rpcd temporary files in the /tmp directories.
278
279
280
281 winbind_rpcd_var_run_t
282
283 - Set files with the winbind_rpcd_var_run_t type, if you want to store
284 the winbind rpcd files under the /run or /var/run directory.
285
286
287
288 winbind_var_run_t
289
290 - Set files with the winbind_var_run_t type, if you want to store the
291 winbind files under the /run or /var/run directory.
292
293
294 Paths:
295 /var/run/winbindd(/.*)?, /var/run/samba/winbindd(/.*)?,
296 /var/lib/samba/winbindd_privileged(/.*)?, /var/cache/samba/win‐
297 bindd_privileged(/.*)?
298
299
300 Note: File context can be temporarily modified with the chcon command.
301 If you want to permanently change the file context you need to use the
302 semanage fcontext command. This will modify the SELinux labeling data‐
303 base. You will need to use restorecon to apply the labels.
304
305
307 semanage fcontext can also be used to manipulate default file context
308 mappings.
309
310 semanage permissive can also be used to manipulate whether or not a
311 process type is permissive.
312
313 semanage module can also be used to enable/disable/install/remove pol‐
314 icy modules.
315
316 semanage boolean can also be used to manipulate the booleans
317
318
319 system-config-selinux is a GUI tool available to customize SELinux pol‐
320 icy settings.
