6 entropyd_selinux - Security Enhanced Linux Policy for the entropyd pro‐
7 cesses
8
10 Security-Enhanced Linux secures the entropyd processes via flexible
11 mandatory access control.
12 The entropyd processes execute with the entropyd_t SELinux type. You
14 can check if you have these processes running by executing the ps com‐
15 mand with the -Z qualifier.
16 For example:
18 ps -eZ | grep entropyd_t
20
24 The entropyd_t SELinux type can be entered via the entropyd_exec_t file
25 type.
26 The default entrypoint paths for the entropyd_t domain are the follow‐
28 ing:
29 /usr/sbin/haveged, /usr/sbin/audio-entropyd
31
33 SELinux defines process types (domains) for each process running on the
34 system
35 You can see the context of a process using the -Z option to ps
37 Policy governs the access confined processes have to files. SELinux
39 entropyd policy is very flexible allowing users to setup their entropyd
40 processes in as secure a method as possible.
41 The following process types are defined for entropyd:
43 entropyd_t
45 Note: semanage permissive -a entropyd_t can be used to make the process
47 type entropyd_t permissive. SELinux does not deny access to permissive
48 process types, but the AVC (SELinux denials) messages are still gener‐
49 ated.
50
53 SELinux policy is customizable based on least access required. en‐
54 tropyd policy is extremely flexible and has several booleans that allow
55 you to manipulate the policy and run entropyd with the tightest access
56 possible.
57 If you want to determine whether entropyd can use audio devices as the
61 source for the entropy feeds, you must turn on the entropyd_use_audio
62 boolean. Enabled by default.
63 setsebool -P entropyd_use_audio 1
65 If you want to allow all domains to execute in fips_mode, you must turn
69 on the fips_mode boolean. Enabled by default.
70 setsebool -P fips_mode 1
72 If you want to allow system to run with NIS, you must turn on the
76 nis_enabled boolean. Disabled by default.
77 setsebool -P nis_enabled 1

83 The SELinux process type entropyd_t can manage files labeled with the
84 following file types. The paths listed are the default paths for these
85 file types. Note the processes UID still need to have DAC permissions.

144 SELinux requires files to have an extended attribute to define the file
145 type.
146 You can see the context of a file using the -Z option to ls
148 Policy governs the access confined processes have to these files.
150 SELinux entropyd policy is very flexible allowing users to setup their
151 entropyd processes in as secure a method as possible.
152 STANDARD FILE CONTEXT
154 SELinux defines the file context types for the entropyd, if you wanted
156 to store files with these types in a diffent paths, you need to execute
157 the semanage command to sepecify alternate labeling and then use re‐
158 storecon to put the labels on disk.
159 semanage fcontext -a -t entropyd_var_run_t '/srv/myentropyd_con‐
161 tent(/.*)?'
162 restorecon -R -v /srv/myentropyd_content
163 Note: SELinux often uses regular expressions to specify labels that
165 match multiple files.
166 The following file types are defined for entropyd:
168 entropyd_exec_t
172 - Set files with the entropyd_exec_t type, if you want to transition an
174 executable to the entropyd_t domain.
175 Paths:
178 /usr/sbin/haveged, /usr/sbin/audio-entropyd
179 entropyd_initrc_exec_t
182 - Set files with the entropyd_initrc_exec_t type, if you want to tran‐
184 sition an executable to the entropyd_initrc_t domain.
185 entropyd_var_run_t
189 - Set files with the entropyd_var_run_t type, if you want to store the
191 entropyd files under the /run or /var/run directory.
192 Paths:
195 /var/run/haveged.pid, /var/run/audio-entropyd.pid
196 Note: File context can be temporarily modified with the chcon command.
199 If you want to permanently change the file context you need to use the
200 semanage fcontext command. This will modify the SELinux labeling data‐
201 base. You will need to use restorecon to apply the labels.
202
205 semanage fcontext can also be used to manipulate default file context
206 mappings.
207 semanage permissive can also be used to manipulate whether or not a
209 process type is permissive.
210 semanage module can also be used to enable/disable/install/remove pol‐
212 icy modules.
213 semanage boolean can also be used to manipulate the booleans
215 system-config-selinux is a GUI tool available to customize SELinux pol‐
218 icy settings.
