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 dontaudit all daemons scheduling requests (setsched,
69 sys_nice), you must turn on the daemons_dontaudit_scheduling boolean.
70 Enabled by default.
71 setsebool -P daemons_dontaudit_scheduling 1
73 If you want to allow all domains to execute in fips_mode, you must turn
77 on the fips_mode boolean. Enabled by default.
78 setsebool -P fips_mode 1
80 If you want to allow system to run with NIS, you must turn on the
84 nis_enabled boolean. Disabled by default.
85 setsebool -P nis_enabled 1

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

152 SELinux requires files to have an extended attribute to define the file
153 type.
154 You can see the context of a file using the -Z option to ls
156 Policy governs the access confined processes have to these files.
158 SELinux entropyd policy is very flexible allowing users to setup their
159 entropyd processes in as secure a method as possible.
160 STANDARD FILE CONTEXT
162 SELinux defines the file context types for the entropyd, if you wanted
164 to store files with these types in a different paths, you need to exe‐
165 cute the semanage command to specify alternate labeling and then use
166 restorecon to put the labels on disk.
167 semanage fcontext -a -t entropyd_exec_t '/srv/entropyd/content(/.*)?'
169 restorecon -R -v /srv/myentropyd_content
170 Note: SELinux often uses regular expressions to specify labels that
172 match multiple files.
173 The following file types are defined for entropyd:
175 entropyd_exec_t
179 - Set files with the entropyd_exec_t type, if you want to transition an
181 executable to the entropyd_t domain.
182 Paths:
185 /usr/sbin/haveged, /usr/sbin/audio-entropyd
186 entropyd_initrc_exec_t
189 - Set files with the entropyd_initrc_exec_t type, if you want to tran‐
191 sition an executable to the entropyd_initrc_t domain.
192 entropyd_var_run_t
196 - Set files with the entropyd_var_run_t type, if you want to store the
198 entropyd files under the /run or /var/run directory.
199 Paths:
202 /var/run/haveged.pid, /var/run/audio-entropyd.pid
203 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.
