6 mdadm_selinux - Security Enhanced Linux Policy for the mdadm processes
7
9 Security-Enhanced Linux secures the mdadm processes via flexible manda‐
10 tory access control.
11
12 The mdadm processes execute with the mdadm_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 mdadm_t
19
20
21
23 The mdadm_t SELinux type can be entered via the mdadm_exec_t file type.
24
25 The default entrypoint paths for the mdadm_t domain are the following:
26
27 /sbin/mdadm, /sbin/mdmon, /sbin/mdmpd, /sbin/iprdump, /sbin/iprinit,
28 /sbin/iprupdate, /usr/sbin/mdadm, /usr/sbin/mdmon, /usr/sbin/mdmpd,
29 /sbin/raid-check, /usr/sbin/iprdump, /usr/sbin/iprinit,
30 /usr/sbin/iprupdate, /usr/sbin/raid-check
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 mdadm policy is very flexible allowing users to setup their mdadm pro‐
40 cesses in as secure a method as possible.
41
42 The following process types are defined for mdadm:
43
44 mdadm_t
45
46 Note: semanage permissive -a mdadm_t can be used to make the process
47 type mdadm_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. mdadm
54 policy is extremely flexible and has several booleans that allow you to
55 manipulate the policy and run mdadm with the tightest access possible.
56
57
58
59 If you want to dontaudit all daemons scheduling requests (setsched,
60 sys_nice), you must turn on the daemons_dontaudit_scheduling boolean.
61 Enabled by default.
62
63 setsebool -P daemons_dontaudit_scheduling 1
64
65
66
67 If you want to allow all domains to execute in fips_mode, you must turn
68 on the fips_mode boolean. Enabled by default.
69
70 setsebool -P fips_mode 1
71
72
73
74 If you want to allow system to run with NIS, you must turn on the
75 nis_enabled boolean. Disabled by default.
76
77 setsebool -P nis_enabled 1
78
79
80
82 The SELinux process type mdadm_t can manage files labeled with the fol‐
83 lowing file types. The paths listed are the default paths for these
84 file types. Note the processes UID still need to have DAC permissions.

176 SELinux requires files to have an extended attribute to define the file
177 type.
178
179 You can see the context of a file using the -Z option to ls
180
181 Policy governs the access confined processes have to these files.
182 SELinux mdadm policy is very flexible allowing users to setup their
183 mdadm processes in as secure a method as possible.
184
185 STANDARD FILE CONTEXT
186
187 SELinux defines the file context types for the mdadm, if you wanted to
188 store files with these types in a different paths, you need to execute
189 the semanage command to specify alternate labeling and then use re‐
190 storecon to put the labels on disk.
191
192 semanage fcontext -a -t mdadm_exec_t '/srv/mdadm/content(/.*)?'
193 restorecon -R -v /srv/mymdadm_content
194
195 Note: SELinux often uses regular expressions to specify labels that
196 match multiple files.
197
198 The following file types are defined for mdadm:
199
200
201
202 mdadm_conf_t
203
204 - Set files with the mdadm_conf_t type, if you want to treat the files
205 as mdadm configuration data, usually stored under the /etc directory.
206
207
208 Paths:
209 /etc/mdadm.conf, /etc/mdadm.conf.anacbak
210
211
212 mdadm_exec_t
213
214 - Set files with the mdadm_exec_t type, if you want to transition an
215 executable to the mdadm_t domain.
216
217
218 Paths:
219 /sbin/mdadm, /sbin/mdmon, /sbin/mdmpd, /sbin/iprdump,
220 /sbin/iprinit, /sbin/iprupdate, /usr/sbin/mdadm, /usr/sbin/mdmon,
221 /usr/sbin/mdmpd, /sbin/raid-check, /usr/sbin/iprdump,
222 /usr/sbin/iprinit, /usr/sbin/iprupdate, /usr/sbin/raid-check
223
224
225 mdadm_initrc_exec_t
226
227 - Set files with the mdadm_initrc_exec_t type, if you want to transi‐
228 tion an executable to the mdadm_initrc_t domain.
229
230
231
232 mdadm_log_t
233
234 - Set files with the mdadm_log_t type, if you want to treat the data as
235 mdadm log data, usually stored under the /var/log directory.
236
237
238 Paths:
239 /var/log/iprdump.*, /var/log/iprdbg
240
241
242 mdadm_tmp_t
243
244 - Set files with the mdadm_tmp_t type, if you want to store mdadm tem‐
245 porary files in the /tmp directories.
246
247
248
249 mdadm_tmpfs_t
250
251 - Set files with the mdadm_tmpfs_t type, if you want to store mdadm
252 files on a tmpfs file system.
253
254
255
256 mdadm_unit_file_t
257
258 - Set files with the mdadm_unit_file_t type, if you want to treat the
259 files as mdadm unit content.
260
261
262 Paths:
263 /usr/lib/systemd/system/mdmon@.*, /usr/lib/systemd/system/mdmoni‐
264 tor.*
265
266
267 mdadm_var_run_t
268
269 - Set files with the mdadm_var_run_t type, if you want to store the
270 mdadm files under the /run or /var/run directory.
271
272
273 Paths:
274 /dev/md/.*, /var/run/mdadm(/.*)?, /dev/.mdadm.map
275
276
277 Note: File context can be temporarily modified with the chcon command.
278 If you want to permanently change the file context you need to use the
279 semanage fcontext command. This will modify the SELinux labeling data‐
280 base. You will need to use restorecon to apply the labels.
281
282
284 semanage fcontext can also be used to manipulate default file context
285 mappings.
286
287 semanage permissive can also be used to manipulate whether or not a
288 process type is permissive.
289
290 semanage module can also be used to enable/disable/install/remove pol‐
291 icy modules.
292
293 semanage boolean can also be used to manipulate the booleans
294
295
296 system-config-selinux is a GUI tool available to customize SELinux pol‐
297 icy settings.
