6 drbd_selinux - Security Enhanced Linux Policy for the drbd processes
7
9 Security-Enhanced Linux secures the drbd processes via flexible manda‐
10 tory access control.
11 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 For example:
17 ps -eZ | grep drbd_t
19
23 The drbd_t SELinux type can be entered via the drbd_exec_t file type.
24 The default entrypoint paths for the drbd_t domain are the following:
26 /sbin/drbdadm, /sbin/drbdsetup, /usr/sbin/drbdadm, /usr/sbin/drbdsetup,
28 /usr/lib/ocf/resource.d/linbit/drbd
29
31 SELinux defines process types (domains) for each process running on the
32 system
33 You can see the context of a process using the -Z option to ps
35 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 The following process types are defined for drbd:
41 drbd_t
43 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
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 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 setsebool -P fips_mode 1
61 If you want to allow system to run with NIS, you must turn on the
65 nis_enabled boolean. Disabled by default.
66 setsebool -P nis_enabled 1
68 If you want to disable kernel module loading, you must turn on the
72 secure_mode_insmod boolean. Enabled by default.
73 setsebool -P secure_mode_insmod 1
75
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.

135 SELinux requires files to have an extended attribute to define the file
136 type.
137 You can see the context of a file using the -Z option to ls
139 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 STANDARD FILE CONTEXT
145 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 semanage fcontext -a -t drbd_tmp_t '/srv/mydrbd_content(/.*)?'
152 restorecon -R -v /srv/mydrbd_content
153 Note: SELinux often uses regular expressions to specify labels that
155 match multiple files.
156 The following file types are defined for drbd:
158 drbd_exec_t
162 - Set files with the drbd_exec_t type, if you want to transition an
164 executable to the drbd_t domain.
165 Paths:
168 /sbin/drbdadm, /sbin/drbdsetup, /usr/sbin/drbdadm, /usr/sbin/drbd‐
169 setup, /usr/lib/ocf/resource.d/linbit/drbd
170 drbd_initrc_exec_t
173 - Set files with the drbd_initrc_exec_t type, if you want to transition
175 an executable to the drbd_initrc_t domain.
176 drbd_lock_t
180 - 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 drbd_tmp_t
187 - Set files with the drbd_tmp_t type, if you want to store drbd tempo‐
189 rary files in the /tmp directories.
190 drbd_var_lib_t
194 - Set files with the drbd_var_lib_t type, if you want to store the drbd
196 files under the /var/lib directory.
197 drbd_var_run_t
201 - 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 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
214 semanage fcontext can also be used to manipulate default file context
215 mappings.
216 semanage permissive can also be used to manipulate whether or not a
218 process type is permissive.
219 semanage module can also be used to enable/disable/install/remove pol‐
221 icy modules.
222 semanage boolean can also be used to manipulate the booleans
224 system-config-selinux is a GUI tool available to customize SELinux pol‐
227 icy settings.
