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
20
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.
48
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 users to resolve user passwd entries directly from
58       ldap rather then using a sssd server, you  must  turn  on  the  authlo‐
59       gin_nsswitch_use_ldap boolean. Disabled by default.
60
61       setsebool -P authlogin_nsswitch_use_ldap 1
62
63
64
65       If you want to allow all domains to execute in fips_mode, you must turn
66       on the fips_mode boolean. Enabled by default.
67
68       setsebool -P fips_mode 1
69
70
71
72       If you want to allow confined applications to run  with  kerberos,  you
73       must turn on the kerberos_enabled boolean. Enabled by default.
74
75       setsebool -P kerberos_enabled 1
76
77
78
79       If  you  want  to  allow  system  to run with NIS, you must turn on the
80       nis_enabled boolean. Disabled by default.
81
82       setsebool -P nis_enabled 1
83
84
85
86       If you want to allow confined applications to use nscd  shared  memory,
87       you must turn on the nscd_use_shm boolean. Disabled by default.
88
89       setsebool -P nscd_use_shm 1
90
91
92
93       If  you  want  to  disable  kernel module loading, you must turn on the
94       secure_mode_insmod boolean. Enabled by default.
95
96       setsebool -P secure_mode_insmod 1

MANAGED FILES

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

FILE CONTEXTS

160       SELinux requires files to have an extended attribute to define the file
161       type.
162
163       You can see the context of a file using the -Z option to ls
164
165       Policy  governs  the  access  confined  processes  have to these files.
166       SELinux drbd policy is very flexible allowing users to setup their drbd
167       processes in as secure a method as possible.
168
169       STANDARD FILE CONTEXT
170
171       SELinux  defines  the file context types for the drbd, if you wanted to
172       store files with these types in a diffent paths, you  need  to  execute
173       the  semanage  command  to  sepecify  alternate  labeling  and then use
174       restorecon to put the labels on disk.
175
176       semanage fcontext -a -t drbd_tmp_t '/srv/mydrbd_content(/.*)?'
177       restorecon -R -v /srv/mydrbd_content
178
179       Note: SELinux often uses regular expressions  to  specify  labels  that
180       match multiple files.
181
182       The following file types are defined for drbd:
183
184
185
186       drbd_exec_t
187
188       -  Set  files  with  the drbd_exec_t type, if you want to transition an
189       executable to the drbd_t domain.
190
191
192       Paths:
193            /sbin/drbdadm, /sbin/drbdsetup, /usr/sbin/drbdadm, /usr/sbin/drbd‐
194            setup, /usr/lib/ocf/resource.d/linbit/drbd
195
196
197       drbd_initrc_exec_t
198
199       - Set files with the drbd_initrc_exec_t type, if you want to transition
200       an executable to the drbd_initrc_t domain.
201
202
203
204       drbd_lock_t
205
206       - Set files with the drbd_lock_t type, if you want to treat  the  files
207       as drbd lock data, stored under the /var/lock directory
208
209
210
211       drbd_tmp_t
212
213       -  Set files with the drbd_tmp_t type, if you want to store drbd tempo‐
214       rary files in the /tmp directories.
215
216
217
218       drbd_var_lib_t
219
220       - Set files with the drbd_var_lib_t type, if you want to store the drbd
221       files under the /var/lib directory.
222
223
224
225       drbd_var_run_t
226
227       - Set files with the drbd_var_run_t type, if you want to store the drbd
228       files under the /run or /var/run directory.
229
230
231
232       Note: File context can be temporarily modified with the chcon  command.
233       If  you want to permanently change the file context you need to use the
234       semanage fcontext command.  This will modify the SELinux labeling data‐
235       base.  You will need to use restorecon to apply the labels.
236
237

COMMANDS

239       semanage  fcontext  can also be used to manipulate default file context
240       mappings.
241
242       semanage permissive can also be used to manipulate  whether  or  not  a
243       process type is permissive.
244
245       semanage  module can also be used to enable/disable/install/remove pol‐
246       icy modules.
247
248       semanage boolean can also be used to manipulate the booleans
249
250
251       system-config-selinux is a GUI tool available to customize SELinux pol‐
252       icy settings.
