6 sbd_selinux - Security Enhanced Linux Policy for the sbd processes
7
9 Security-Enhanced Linux secures the sbd processes via flexible manda‐
10 tory access control.
11
12 The sbd processes execute with the sbd_t SELinux type. You can check if
13 you have these processes running by executing the ps command with the
14 -Z qualifier.
15
16 For example:
17
18 ps -eZ | grep sbd_t
19
20
21
23 The sbd_t SELinux type can be entered via the sbd_exec_t file type.
24
25 The default entrypoint paths for the sbd_t domain are the following:
26
27 /usr/sbin/sbd
28
30 SELinux defines process types (domains) for each process running on the
31 system
32
33 You can see the context of a process using the -Z option to ps
34
35 Policy governs the access confined processes have to files. SELinux
36 sbd policy is very flexible allowing users to setup their sbd processes
37 in as secure a method as possible.
38
39 The following process types are defined for sbd:
40
41 sbd_t
42
43 Note: semanage permissive -a sbd_t can be used to make the process type
44 sbd_t permissive. SELinux does not deny access to permissive process
45 types, but the AVC (SELinux denials) messages are still generated.
46
47
49 SELinux policy is customizable based on least access required. sbd
50 policy is extremely flexible and has several booleans that allow you to
51 manipulate the policy and run sbd with the tightest access possible.
52
53
54
55 If you want to allow all domains to execute in fips_mode, you must turn
56 on the fips_mode boolean. Enabled by default.
57
58 setsebool -P fips_mode 1
59
60
61
62 If you want to allow system to run with NIS, you must turn on the
63 nis_enabled boolean. Disabled by default.
64
65 setsebool -P nis_enabled 1
66
67
68
70 The SELinux process type sbd_t can manage files labeled with the fol‐
71 lowing file types. The paths listed are the default paths for these
72 file types. Note the processes UID still need to have DAC permissions.

139 SELinux requires files to have an extended attribute to define the file
140 type.
141
142 You can see the context of a file using the -Z option to ls
143
144 Policy governs the access confined processes have to these files.
145 SELinux sbd policy is very flexible allowing users to setup their sbd
146 processes in as secure a method as possible.
147
148 STANDARD FILE CONTEXT
149
150 SELinux defines the file context types for the sbd, if you wanted to
151 store files with these types in a diffent paths, you need to execute
152 the semanage command to sepecify alternate labeling and then use re‐
153 storecon to put the labels on disk.
154
155 semanage fcontext -a -t sbd_tmpfs_t '/srv/mysbd_content(/.*)?'
156 restorecon -R -v /srv/mysbd_content
157
158 Note: SELinux often uses regular expressions to specify labels that
159 match multiple files.
160
161 The following file types are defined for sbd:
162
163
164
165 sbd_exec_t
166
167 - Set files with the sbd_exec_t type, if you want to transition an exe‐
168 cutable to the sbd_t domain.
169
170
171
172 sbd_tmpfs_t
173
174 - Set files with the sbd_tmpfs_t type, if you want to store sbd files
175 on a tmpfs file system.
176
177
178
179 sbd_unit_file_t
180
181 - Set files with the sbd_unit_file_t type, if you want to treat the
182 files as sbd unit content.
183
184
185 Paths:
186 /usr/lib/systemd/system/sbd.service, /usr/lib/systemd/sys‐
187 tem/sbd_remote.service
188
189
190 sbd_var_run_t
191
192 - Set files with the sbd_var_run_t type, if you want to store the sbd
193 files under the /run or /var/run directory.
194
195
196
197 Note: File context can be temporarily modified with the chcon command.
198 If you want to permanently change the file context you need to use the
199 semanage fcontext command. This will modify the SELinux labeling data‐
200 base. You will need to use restorecon to apply the labels.
201
202
204 semanage fcontext can also be used to manipulate default file context
205 mappings.
206
207 semanage permissive can also be used to manipulate whether or not a
208 process type is permissive.
209
210 semanage module can also be used to enable/disable/install/remove pol‐
211 icy modules.
212
213 semanage boolean can also be used to manipulate the booleans
214
215
216 system-config-selinux is a GUI tool available to customize SELinux pol‐
217 icy settings.
