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 allow users to resolve user passwd entries directly from
56 ldap rather then using a sssd server, you must turn on the authlo‐
57 gin_nsswitch_use_ldap boolean. Disabled by default.
58 setsebool -P authlogin_nsswitch_use_ldap 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 confined applications to run with kerberos, you
71 must turn on the kerberos_enabled boolean. Enabled by default.
72 setsebool -P kerberos_enabled 1
74 If you want to allow system to run with NIS, you must turn on the
78 nis_enabled boolean. Disabled by default.
79 setsebool -P nis_enabled 1
81 If you want to allow confined applications to use nscd shared memory,
85 you must turn on the nscd_use_shm boolean. Enabled by default.
86 setsebool -P nscd_use_shm 1
88
92 The SELinux process type sbd_t can manage files labeled with the fol‐
93 lowing file types. The paths listed are the default paths for these
94 file types. Note the processes UID still need to have DAC permissions.

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