NAME

6       mdadm_selinux - Security Enhanced Linux Policy for the mdadm processes
7

DESCRIPTION

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

ENTRYPOINTS

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

PROCESS TYPES

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

BOOLEANS

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 allow users to resolve user passwd entries directly from
60       ldap rather then using a sssd server, you  must  turn  on  the  authlo‐
61       gin_nsswitch_use_ldap boolean. Disabled by default.
62
63       setsebool -P authlogin_nsswitch_use_ldap 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 confined applications to run  with  kerberos,  you
75       must turn on the kerberos_enabled boolean. Disabled by default.
76
77       setsebool -P kerberos_enabled 1
78
79
80
81       If  you  want  to  allow  system  to run with NIS, you must turn on the
82       nis_enabled boolean. Disabled by default.
83
84       setsebool -P nis_enabled 1
85
86
87
88       If you want to allow confined applications to use nscd  shared  memory,
89       you must turn on the nscd_use_shm boolean. Disabled by default.
90
91       setsebool -P nscd_use_shm 1
92
93
94

MANAGED FILES

96       The SELinux process type mdadm_t can manage files labeled with the fol‐
97       lowing file types.  The paths listed are the default  paths  for  these
98       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

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

COMMANDS

287       semanage  fcontext  can also be used to manipulate default file context
288       mappings.
289
290       semanage permissive can also be used to manipulate  whether  or  not  a
291       process type is permissive.
292
293       semanage  module can also be used to enable/disable/install/remove pol‐
294       icy modules.
295
296       semanage boolean can also be used to manipulate the booleans
297
298
299       system-config-selinux is a GUI tool available to customize SELinux pol‐
300       icy settings.
