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 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 For example:
17 ps -eZ | grep sbd_t
19
23 The sbd_t SELinux type can be entered via the sbd_exec_t file type.
24 The default entrypoint paths for the sbd_t domain are the following:
26 /usr/sbin/sbd
28
30 SELinux defines process types (domains) for each process running on the
31 system
32 You can see the context of a process using the -Z option to ps
34 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 The following process types are defined for sbd:
40 sbd_t
42 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
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 If you want to dontaudit all daemons scheduling requests (setsched,
56 sys_nice), you must turn on the daemons_dontaudit_scheduling boolean.
57 Enabled by default.
58 setsebool -P daemons_dontaudit_scheduling 1
60 If you want to allow all domains to execute in fips_mode, you must turn
64 on the fips_mode boolean. Enabled by default.
65 setsebool -P fips_mode 1
67 If you want to allow system to run with NIS, you must turn on the
71 nis_enabled boolean. Disabled by default.
72 setsebool -P nis_enabled 1
74
78 The SELinux process type sbd_t can manage files labeled with the fol‐
79 lowing file types. The paths listed are the default paths for these
80 file types. Note the processes UID still need to have DAC permissions.

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