NAME

6       rngd_selinux - Security Enhanced Linux Policy for the rngd processes
7

DESCRIPTION

9       Security-Enhanced  Linux secures the rngd processes via flexible manda‐
10       tory access control.
11
12       The rngd processes execute with the rngd_t SELinux type. You can  check
13       if  you  have  these processes running by executing the ps command with
14       the -Z qualifier.
15
16       For example:
17
18       ps -eZ | grep rngd_t

21

ENTRYPOINTS

23       The rngd_t SELinux type can be entered via the rngd_exec_t file type.
24
25       The default entrypoint paths for the rngd_t domain are the following:
26
27       /usr/sbin/rngd
28

PROCESS TYPES

30       SELinux defines process types (domains) for each process running on the
31       system
32
33       You can see the context of a process using the -Z option to ps
34
35       Policy  governs  the  access confined processes have to files.  SELinux
36       rngd policy is very flexible allowing users to setup  their  rngd  pro‐
37       cesses in as secure a method as possible.
38
39       The following process types are defined for rngd:
40
41       rngd_t
42
43       Note:  semanage  permissive  -a  rngd_t can be used to make the process
44       type rngd_t permissive. SELinux does  not  deny  access  to  permissive
45       process  types, but the AVC (SELinux denials) messages are still gener‐
46       ated.

BOOLEANS

50       SELinux policy is customizable based on least  access  required.   rngd
51       policy is extremely flexible and has several booleans that allow you to
52       manipulate the policy and run rngd with the tightest access possible.
53
54
55
56       If you want to allow rngd_t domain to use executable memory,  you  must
57       turn on the rngd_execmem boolean. Disabled by default.
58
59       setsebool -P rngd_execmem 1
60
61
62
63       If you want to allow all domains to execute in fips_mode, you must turn
64       on the fips_mode boolean. Enabled by default.
65
66       setsebool -P fips_mode 1
67
68
69
70       If you want to allow system to run with  NIS,  you  must  turn  on  the
71       nis_enabled boolean. Disabled by default.
72
73       setsebool -P nis_enabled 1
74

76

MANAGED FILES

78       The  SELinux process type rngd_t can manage files labeled with the fol‐
79       lowing file types.  The paths listed are the default  paths  for  these
80       file types.  Note the processes UID still need to have DAC permissions.
81

FILE CONTEXTS

123       SELinux requires files to have an extended attribute to define the file
124       type.
125
126       You can see the context of a file using the -Z option to ls
127
128       Policy governs the access  confined  processes  have  to  these  files.
129       SELinux rngd policy is very flexible allowing users to setup their rngd
130       processes in as secure a method as possible.
131
132       STANDARD FILE CONTEXT
133
134       SELinux defines the file context types for the rngd, if you  wanted  to
135       store  files  with  these types in a diffent paths, you need to execute
136       the semanage command  to  sepecify  alternate  labeling  and  then  use
137       restorecon to put the labels on disk.
138
139       semanage fcontext -a -t rngd_var_run_t '/srv/myrngd_content(/.*)?'
140       restorecon -R -v /srv/myrngd_content
141
142       Note:  SELinux  often  uses  regular expressions to specify labels that
143       match multiple files.
144
145       The following file types are defined for rngd:
146
147
148
149       rngd_exec_t
150
151       - Set files with the rngd_exec_t type, if you  want  to  transition  an
152       executable to the rngd_t domain.
153
154
155
156       rngd_initrc_exec_t
157
158       - Set files with the rngd_initrc_exec_t type, if you want to transition
159       an executable to the rngd_initrc_t domain.
160
161
162
163       rngd_unit_file_t
164
165       - Set files with the rngd_unit_file_t type, if you want  to  treat  the
166       files as rngd unit content.
167
168
169
170       rngd_var_run_t
171
172       - Set files with the rngd_var_run_t type, if you want to store the rngd
173       files under the /run or /var/run directory.
174
175
176
177       Note: File context can be temporarily modified with the chcon  command.
178       If  you want to permanently change the file context you need to use the
179       semanage fcontext command.  This will modify the SELinux labeling data‐
180       base.  You will need to use restorecon to apply the labels.
181
182

COMMANDS

184       semanage  fcontext  can also be used to manipulate default file context
185       mappings.
186
187       semanage permissive can also be used to manipulate  whether  or  not  a
188       process type is permissive.
189
190       semanage  module can also be used to enable/disable/install/remove pol‐
191       icy modules.
192
193       semanage boolean can also be used to manipulate the booleans
194
195
196       system-config-selinux is a GUI tool available to customize SELinux pol‐
197       icy settings.
