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
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.
57
58
59
60 If you want to allow all domains to execute in fips_mode, you must turn
61 on the fips_mode boolean. Enabled by default.
62
63 setsebool -P fips_mode 1
64
65
66
67 If you want to allow system to run with NIS, you must turn on the
68 nis_enabled boolean. Disabled by default.
69
70 setsebool -P nis_enabled 1
71
72
73
75 The SELinux process type winbind_t can manage files labeled with the
76 following file types. The paths listed are the default paths for these
77 file types. Note the processes UID still need to have DAC permissions.

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