NAME

6       entropyd_selinux - Security Enhanced Linux Policy for the entropyd pro‐
7       cesses
8

DESCRIPTION

10       Security-Enhanced Linux secures the  entropyd  processes  via  flexible
11       mandatory access control.
12
13       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
17       For example:
18
19       ps -eZ | grep entropyd_t
20
21
22

ENTRYPOINTS

24       The entropyd_t SELinux type can be entered via the entropyd_exec_t file
25       type.
26
27       The default entrypoint paths for the entropyd_t domain are the  follow‐
28       ing:
29
30       /usr/sbin/haveged, /usr/sbin/audio-entropyd
31

PROCESS TYPES

33       SELinux defines process types (domains) for each process running on the
34       system
35
36       You can see the context of a process using the -Z option to ps
37
38       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
42       The following process types are defined for entropyd:
43
44       entropyd_t
45
46       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
51

BOOLEANS

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
58

MANAGED FILES

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

FILE CONTEXTS

225       SELinux requires files to have an extended attribute to define the file
226       type.
227
228       You can see the context of a file using the -Z option to ls
229
230       Policy  governs  the  access  confined  processes  have to these files.
231       SELinux entropyd policy is very flexible allowing users to setup  their
232       entropyd processes in as secure a method as possible.
233
234       STANDARD FILE CONTEXT
235
236       SELinux  defines the file context types for the entropyd, if you wanted
237       to store files with these types in a diffent paths, you need to execute
238       the  semanage  command  to  sepecify  alternate  labeling  and then use
239       restorecon to put the labels on disk.
240
241       semanage  fcontext  -a  -t   entropyd_var_run_t   '/srv/myentropyd_con‐
242       tent(/.*)?'
243       restorecon -R -v /srv/myentropyd_content
244
245       Note:  SELinux  often  uses  regular expressions to specify labels that
246       match multiple files.
247
248       The following file types are defined for entropyd:
249
250
251
252       entropyd_exec_t
253
254       - Set files with the entropyd_exec_t type, if you want to transition an
255       executable to the entropyd_t domain.
256
257
258       Paths:
259            /usr/sbin/haveged, /usr/sbin/audio-entropyd
260
261
262       entropyd_initrc_exec_t
263
264       -  Set files with the entropyd_initrc_exec_t type, if you want to tran‐
265       sition an executable to the entropyd_initrc_t domain.
266
267
268
269       entropyd_var_run_t
270
271       - Set files with the entropyd_var_run_t type, if you want to store  the
272       entropyd files under the /run or /var/run directory.
273
274
275       Paths:
276            /var/run/haveged.pid, /var/run/audio-entropyd.pid
277
278
279       Note:  File context can be temporarily modified with the chcon command.
280       If you want to permanently change the file context you need to use  the
281       semanage fcontext command.  This will modify the SELinux labeling data‐
282       base.  You will need to use restorecon to apply the labels.
283
284

COMMANDS

286       semanage fcontext can also be used to manipulate default  file  context
287       mappings.
288
289       semanage  permissive  can  also  be used to manipulate whether or not a
290       process type is permissive.
291
292       semanage module can also be used to enable/disable/install/remove  pol‐
293       icy modules.
294
295       semanage boolean can also be used to manipulate the booleans
296
297
298       system-config-selinux is a GUI tool available to customize SELinux pol‐
299       icy settings.
