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.
54 entropyd policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run entropyd with the tightest
56 access possible.
57 If you want to allow all daemons to write corefiles to /, you must turn
61 on the allow_daemons_dump_core boolean. Disabled by default.
62 setsebool -P allow_daemons_dump_core 1
64 If you want to allow all daemons to use tcp wrappers, you must turn on
68 the allow_daemons_use_tcp_wrapper boolean. Disabled by default.
69 setsebool -P allow_daemons_use_tcp_wrapper 1
71 If you want to allow all daemons the ability to read/write terminals,
75 you must turn on the allow_daemons_use_tty boolean. Disabled by
76 default.
77 setsebool -P allow_daemons_use_tty 1
79 If you want to allow all domains to use other domains file descriptors,
83 you must turn on the allow_domain_fd_use boolean. Enabled by default.
84 setsebool -P allow_domain_fd_use 1

90 turn on the allow_ptrace boolean. Disabled by default.
91 setsebool -P allow_ptrace 1

97 daemons_enable_cluster_mode boolean. Disabled by default.
98 setsebool -P daemons_enable_cluster_mode 1
100 If you want to allow all domains to have the kernel load modules, you
104 must turn on the domain_kernel_load_modules boolean. Disabled by
105 default.
106 setsebool -P domain_kernel_load_modules 1
108 If you want to allow all domains to execute in fips_mode, you must turn
112 on the fips_mode boolean. Enabled by default.
113 setsebool -P fips_mode 1
115 If you want to enable reading of urandom for all domains, you must turn
119 on the global_ssp boolean. Disabled by default.
120 setsebool -P global_ssp 1
122 If you want to enable support for upstart as the init program, you must
126 turn on the init_upstart boolean. Enabled by default.
127 setsebool -P init_upstart 1
129
133 The SELinux process type entropyd_t can manage files labeled with the
134 following file types. The paths listed are the default paths for these
135 file types. Note the processes UID still need to have DAC permissions.

201 SELinux requires files to have an extended attribute to define the file
202 type.
203 You can see the context of a file using the -Z option to ls
205 Policy governs the access confined processes have to these files.
207 SELinux entropyd policy is very flexible allowing users to setup their
208 entropyd processes in as secure a method as possible.
209 STANDARD FILE CONTEXT
211 SELinux defines the file context types for the entropyd, if you wanted
213 to store files with these types in a diffent paths, you need to execute
214 the semanage command to sepecify alternate labeling and then use
215 restorecon to put the labels on disk.
216 semanage fcontext -a -t entropyd_var_run_t '/srv/myentropyd_con‐
218 tent(/.*)?'
219 restorecon -R -v /srv/myentropyd_content
220 Note: SELinux often uses regular expressions to specify labels that
222 match multiple files.
223 The following file types are defined for entropyd:
225 entropyd_exec_t
229 - Set files with the entropyd_exec_t type, if you want to transition an
231 executable to the entropyd_t domain.
232 Paths:
235 /usr/sbin/haveged, /usr/sbin/audio-entropyd
236 entropyd_initrc_exec_t
239 - Set files with the entropyd_initrc_exec_t type, if you want to tran‐
241 sition an executable to the entropyd_initrc_t domain.
242 entropyd_var_run_t
246 - Set files with the entropyd_var_run_t type, if you want to store the
248 entropyd files under the /run or /var/run directory.
249 Paths:
252 /var/run/haveged.pid, /var/run/audio-entropyd.pid
253 Note: File context can be temporarily modified with the chcon command.
256 If you want to permanently change the file context you need to use the
257 semanage fcontext command. This will modify the SELinux labeling data‐
258 base. You will need to use restorecon to apply the labels.
259
262 semanage fcontext can also be used to manipulate default file context
263 mappings.
264 semanage permissive can also be used to manipulate whether or not a
266 process type is permissive.
267 semanage module can also be used to enable/disable/install/remove pol‐
269 icy modules.
270 semanage boolean can also be used to manipulate the booleans
272 system-config-selinux is a GUI tool available to customize SELinux pol‐
275 icy settings.
