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.

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
72       secure_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

135       SELinux requires files to have an extended attribute to define the file
136       type.
137
138       You can see the context of a file using the -Z option to ls
139
140       Policy  governs  the  access  confined  processes  have to these files.
141       SELinux drbd policy is very flexible allowing users to setup their drbd
142       processes in as secure a method as possible.
143
144       STANDARD FILE CONTEXT
145
146       SELinux  defines  the file context types for the drbd, if you wanted to
147       store files with these types in a diffent paths, you  need  to  execute
148       the  semanage  command  to  sepecify  alternate  labeling  and then use
149       restorecon to put the labels on disk.
150
151       semanage fcontext -a -t drbd_tmp_t '/srv/mydrbd_content(/.*)?'
152       restorecon -R -v /srv/mydrbd_content
153
154       Note: SELinux often uses regular expressions  to  specify  labels  that
155       match multiple files.
156
157       The following file types are defined for drbd:
158
159
160
161       drbd_exec_t
162
163       -  Set  files  with  the drbd_exec_t type, if you want to transition an
164       executable to the drbd_t domain.
165
166
167       Paths:
168            /sbin/drbdadm, /sbin/drbdsetup, /usr/sbin/drbdadm, /usr/sbin/drbd‐
169            setup, /usr/lib/ocf/resource.d/linbit/drbd
170
171
172       drbd_initrc_exec_t
173
174       - Set files with the drbd_initrc_exec_t type, if you want to transition
175       an executable to the drbd_initrc_t domain.
176
177
178
179       drbd_lock_t
180
181       - Set files with the drbd_lock_t type, if you want to treat  the  files
182       as drbd lock data, stored under the /var/lock directory
183
184
185
186       drbd_tmp_t
187
188       -  Set files with the drbd_tmp_t type, if you want to store drbd tempo‐
189       rary files in the /tmp directories.
190
191
192
193       drbd_var_lib_t
194
195       - Set files with the drbd_var_lib_t type, if you want to store the drbd
196       files under the /var/lib directory.
197
198
199
200       drbd_var_run_t
201
202       - Set files with the drbd_var_run_t type, if you want to store the drbd
203       files under the /run or /var/run directory.
204
205
206
207       Note: File context can be temporarily modified with the chcon  command.
208       If  you want to permanently change the file context you need to use the
209       semanage fcontext command.  This will modify the SELinux labeling data‐
210       base.  You will need to use restorecon to apply the labels.
211
212

COMMANDS

214       semanage  fcontext  can also be used to manipulate default file context
215       mappings.
216
217       semanage permissive can also be used to manipulate  whether  or  not  a
218       process type is permissive.
219
220       semanage  module can also be used to enable/disable/install/remove pol‐
221       icy modules.
222
223       semanage boolean can also be used to manipulate the booleans
224
225
226       system-config-selinux is a GUI tool available to customize SELinux pol‐
227       icy settings.
