6 rngd_selinux - Security Enhanced Linux Policy for the rngd processes
7
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
19
20
21
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
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.
47
48
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 all domains to execute in fips_mode, you must turn
57 on the fips_mode boolean. Enabled by default.
58
59 setsebool -P fips_mode 1
60
61
62
64 The SELinux process type rngd_t can manage files labeled with the fol‐
65 lowing file types. The paths listed are the default paths for these
66 file types. Note the processes UID still need to have DAC permissions.

109 SELinux requires files to have an extended attribute to define the file
110 type.
111
112 You can see the context of a file using the -Z option to ls
113
114 Policy governs the access confined processes have to these files.
115 SELinux rngd policy is very flexible allowing users to setup their rngd
116 processes in as secure a method as possible.
117
118 STANDARD FILE CONTEXT
119
120 SELinux defines the file context types for the rngd, if you wanted to
121 store files with these types in a diffent paths, you need to execute
122 the semanage command to sepecify alternate labeling and then use
123 restorecon to put the labels on disk.
124
125 semanage fcontext -a -t rngd_var_run_t '/srv/myrngd_content(/.*)?'
126 restorecon -R -v /srv/myrngd_content
127
128 Note: SELinux often uses regular expressions to specify labels that
129 match multiple files.
130
131 The following file types are defined for rngd:
132
133
134
135 rngd_exec_t
136
137 - Set files with the rngd_exec_t type, if you want to transition an
138 executable to the rngd_t domain.
139
140
141
142 rngd_initrc_exec_t
143
144 - Set files with the rngd_initrc_exec_t type, if you want to transition
145 an executable to the rngd_initrc_t domain.
146
147
148
149 rngd_unit_file_t
150
151 - Set files with the rngd_unit_file_t type, if you want to treat the
152 files as rngd unit content.
153
154
155
156 rngd_var_run_t
157
158 - Set files with the rngd_var_run_t type, if you want to store the rngd
159 files under the /run or /var/run directory.
160
161
162
163 Note: File context can be temporarily modified with the chcon command.
164 If you want to permanently change the file context you need to use the
165 semanage fcontext command. This will modify the SELinux labeling data‐
166 base. You will need to use restorecon to apply the labels.
167
168
170 semanage fcontext can also be used to manipulate default file context
171 mappings.
172
173 semanage permissive can also be used to manipulate whether or not a
174 process type is permissive.
175
176 semanage module can also be used to enable/disable/install/remove pol‐
177 icy modules.
178
179 semanage boolean can also be used to manipulate the booleans
180
181
182 system-config-selinux is a GUI tool available to customize SELinux pol‐
183 icy settings.
