NAME

6       drbd_selinux - Security Enhanced Linux Policy for the drbd processes
7

DESCRIPTION

9       Security-Enhanced  Linux secures the drbd processes via flexible manda‐
10       tory access control.
11
12       The drbd processes execute with the drbd_t SELinux type. You can  check
13       if  you  have  these processes running by executing the ps command with
14       the -Z qualifier.
15
16       For example:
17
18       ps -eZ | grep drbd_t
19

21

ENTRYPOINTS

23       The drbd_t SELinux type can be entered via the drbd_exec_t file type.
24
25       The default entrypoint paths for the drbd_t domain are the following:
26
27       /sbin/drbdadm, /sbin/drbdsetup, /usr/sbin/drbdadm, /usr/sbin/drbdsetup,
28       /usr/lib/ocf/resource.d/linbit/drbd
29

PROCESS TYPES

31       SELinux defines process types (domains) for each process running on the
32       system
33
34       You can see the context of a process using the -Z option to ps
35
36       Policy governs the access confined processes have  to  files.   SELinux
37       drbd  policy  is  very flexible allowing users to setup their drbd pro‐
38       cesses in as secure a method as possible.
39
40       The following process types are defined for drbd:
41
42       drbd_t
43
44       Note: semanage permissive -a drbd_t can be used  to  make  the  process
45       type  drbd_t  permissive.  SELinux  does  not deny access to permissive
46       process types, but the AVC (SELinux denials) messages are still  gener‐
47       ated.

49

BOOLEANS

51       SELinux  policy  is  customizable based on least access required.  drbd
52       policy is extremely flexible and has several booleans that allow you to
53       manipulate the policy and run drbd with the tightest access possible.
54
55
56
57       If you want to allow all domains to execute in fips_mode, you must turn
58       on the fips_mode boolean. Enabled by default.
59
60       setsebool -P fips_mode 1
61
62
63
64       If you want to allow system to run with  NIS,  you  must  turn  on  the
65       nis_enabled boolean. Disabled by default.
66
67       setsebool -P nis_enabled 1
68
69
70
71       If  you want to disable kernel module loading, you must turn on the se‐
72       cure_mode_insmod boolean. Enabled by default.
73
74       setsebool -P secure_mode_insmod 1

MANAGED FILES

79       The SELinux process type drbd_t can manage files labeled with the  fol‐
80       lowing  file  types.   The paths listed are the default paths for these
81       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

153       SELinux requires files to have an extended attribute to define the file
154       type.
155
156       You can see the context of a file using the -Z option to ls
157
158       Policy  governs  the  access  confined  processes  have to these files.
159       SELinux drbd policy is very flexible allowing users to setup their drbd
160       processes in as secure a method as possible.
161
162       STANDARD FILE CONTEXT
163
164       SELinux  defines  the file context types for the drbd, if you wanted to
165       store files with these types in a diffent paths, you  need  to  execute
166       the  semanage  command  to  specify alternate labeling and then use re‐
167       storecon to put the labels on disk.
168
169       semanage fcontext -a -t drbd_tmp_t '/srv/mydrbd_content(/.*)?'
170       restorecon -R -v /srv/mydrbd_content
171
172       Note: SELinux often uses regular expressions  to  specify  labels  that
173       match multiple files.
174
175       The following file types are defined for drbd:
176
177
178
179       drbd_exec_t
180
181       - Set files with the drbd_exec_t type, if you want to transition an ex‐
182       ecutable to the drbd_t domain.
183
184
185       Paths:
186            /sbin/drbdadm, /sbin/drbdsetup, /usr/sbin/drbdadm, /usr/sbin/drbd‐
187            setup, /usr/lib/ocf/resource.d/linbit/drbd
188
189
190       drbd_initrc_exec_t
191
192       - Set files with the drbd_initrc_exec_t type, if you want to transition
193       an executable to the drbd_initrc_t domain.
194
195
196
197       drbd_lock_t
198
199       - Set files with the drbd_lock_t type, if you want to treat  the  files
200       as drbd lock data, stored under the /var/lock directory
201
202
203
204       drbd_tmp_t
205
206       -  Set files with the drbd_tmp_t type, if you want to store drbd tempo‐
207       rary files in the /tmp directories.
208
209
210
211       drbd_var_lib_t
212
213       - Set files with the drbd_var_lib_t type, if you want to store the drbd
214       files under the /var/lib directory.
215
216
217
218       drbd_var_run_t
219
220       - Set files with the drbd_var_run_t type, if you want to store the drbd
221       files under the /run or /var/run directory.
222
223
224
225       Note: File context can be temporarily modified with the chcon  command.
226       If  you want to permanently change the file context you need to use the
227       semanage fcontext command.  This will modify the SELinux labeling data‐
228       base.  You will need to use restorecon to apply the labels.
229
230

COMMANDS

232       semanage  fcontext  can also be used to manipulate default file context
233       mappings.
234
235       semanage permissive can also be used to manipulate  whether  or  not  a
236       process type is permissive.
237
238       semanage  module can also be used to enable/disable/install/remove pol‐
239       icy modules.
240
241       semanage boolean can also be used to manipulate the booleans
242
243
244       system-config-selinux is a GUI tool available to customize SELinux pol‐
245       icy settings.
