6 wdmd_selinux - Security Enhanced Linux Policy for the wdmd processes
7
9 Security-Enhanced Linux secures the wdmd processes via flexible manda‐
10 tory access control.
11 The wdmd processes execute with the wdmd_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 wdmd_t
19
23 The wdmd_t SELinux type can be entered via the wdmd_exec_t file type.
24 The default entrypoint paths for the wdmd_t domain are the following:
26 /usr/sbin/wdmd
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 wdmd policy is very flexible allowing users to setup their wdmd pro‐
37 cesses in as secure a method as possible.
38 The following process types are defined for wdmd:
40 wdmd_t
42 Note: semanage permissive -a wdmd_t can be used to make the process
44 type wdmd_t permissive. SELinux does not deny access to permissive
45 process types, but the AVC (SELinux denials) messages are still gener‐
46 ated.
47
50 SELinux policy is customizable based on least access required. wdmd
51 policy is extremely flexible and has several booleans that allow you to
52 manipulate the policy and run wdmd with the tightest access possible.
53 If you want to allow users to resolve user passwd entries directly from
57 ldap rather then using a sssd server, you must turn on the authlo‐
58 gin_nsswitch_use_ldap boolean. Disabled by default.
59 setsebool -P authlogin_nsswitch_use_ldap 1
61 If you want to allow all domains to execute in fips_mode, you must turn
65 on the fips_mode boolean. Enabled by default.
66 setsebool -P fips_mode 1
68 If you want to allow confined applications to run with kerberos, you
72 must turn on the kerberos_enabled boolean. Disabled by default.
73 setsebool -P kerberos_enabled 1
75 If you want to allow system to run with NIS, you must turn on the
79 nis_enabled boolean. Disabled by default.
80 setsebool -P nis_enabled 1
82 If you want to allow confined applications to use nscd shared memory,
86 you must turn on the nscd_use_shm boolean. Disabled by default.
87 setsebool -P nscd_use_shm 1
89
93 The SELinux process type wdmd_t can manage files labeled with the fol‐
94 lowing file types. The paths listed are the default paths for these
95 file types. Note the processes UID still need to have DAC permissions.

145 SELinux requires files to have an extended attribute to define the file
146 type.
147 You can see the context of a file using the -Z option to ls
149 Policy governs the access confined processes have to these files.
151 SELinux wdmd policy is very flexible allowing users to setup their wdmd
152 processes in as secure a method as possible.
153 STANDARD FILE CONTEXT
155 SELinux defines the file context types for the wdmd, if you wanted to
157 store files with these types in a diffent paths, you need to execute
158 the semanage command to sepecify alternate labeling and then use
159 restorecon to put the labels on disk.
160 semanage fcontext -a -t wdmd_var_run_t '/srv/mywdmd_content(/.*)?'
162 restorecon -R -v /srv/mywdmd_content
163 Note: SELinux often uses regular expressions to specify labels that
165 match multiple files.
166 The following file types are defined for wdmd:
168 wdmd_exec_t
172 - Set files with the wdmd_exec_t type, if you want to transition an
174 executable to the wdmd_t domain.
175 wdmd_initrc_exec_t
179 - Set files with the wdmd_initrc_exec_t type, if you want to transition
181 an executable to the wdmd_initrc_t domain.
182 wdmd_tmpfs_t
186 - Set files with the wdmd_tmpfs_t type, if you want to store wdmd files
188 on a tmpfs file system.
189 wdmd_var_run_t
193 - Set files with the wdmd_var_run_t type, if you want to store the wdmd
195 files under the /run or /var/run directory.
196 Paths:
199 /var/run/wdmd(/.*)?, /var/run/checkquorum-timer
200 Note: File context can be temporarily modified with the chcon command.
203 If you want to permanently change the file context you need to use the
204 semanage fcontext command. This will modify the SELinux labeling data‐
205 base. You will need to use restorecon to apply the labels.
206
209 semanage fcontext can also be used to manipulate default file context
210 mappings.
211 semanage permissive can also be used to manipulate whether or not a
213 process type is permissive.
214 semanage module can also be used to enable/disable/install/remove pol‐
216 icy modules.
217 semanage boolean can also be used to manipulate the booleans
219 system-config-selinux is a GUI tool available to customize SELinux pol‐
222 icy settings.
