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 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 For example:
17 ps -eZ | grep rngd_t
19
23 The rngd_t SELinux type can be entered via the rngd_exec_t file type.
24 The default entrypoint paths for the rngd_t domain are the following:
26 /usr/sbin/rngd
28
30 SELinux defines process types (domains) for each process running on the
31 system
32 You can see the context of a process using the -Z option to ps
34 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 The following process types are defined for rngd:
40 rngd_t
42 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
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 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 setsebool -P rngd_execmem 1
60 If you want to dontaudit all daemons scheduling requests (setsched,
64 sys_nice), you must turn on the daemons_dontaudit_scheduling boolean.
65 Enabled by default.
66 setsebool -P daemons_dontaudit_scheduling 1
68 If you want to allow all domains to execute in fips_mode, you must turn
72 on the fips_mode boolean. Enabled by default.
73 setsebool -P fips_mode 1
75 If you want to allow system to run with NIS, you must turn on the
79 nis_enabled boolean. Disabled by default.
80 setsebool -P nis_enabled 1
82
86 The SELinux process type rngd_t can manage files labeled with the fol‐
87 lowing file types. The paths listed are the default paths for these
88 file types. Note the processes UID still need to have DAC permissions.

146 SELinux requires files to have an extended attribute to define the file
147 type.
148 You can see the context of a file using the -Z option to ls
150 Policy governs the access confined processes have to these files.
152 SELinux rngd policy is very flexible allowing users to setup their rngd
153 processes in as secure a method as possible.
154 STANDARD FILE CONTEXT
156 SELinux defines the file context types for the rngd, if you wanted to
158 store files with these types in a different paths, you need to execute
159 the semanage command to specify alternate labeling and then use re‐
160 storecon to put the labels on disk.
161 semanage fcontext -a -t rngd_exec_t '/srv/rngd/content(/.*)?'
163 restorecon -R -v /srv/myrngd_content
164 Note: SELinux often uses regular expressions to specify labels that
166 match multiple files.
167 The following file types are defined for rngd:
169 rngd_exec_t
173 - Set files with the rngd_exec_t type, if you want to transition an ex‐
175 ecutable to the rngd_t domain.
176 rngd_initrc_exec_t
180 - Set files with the rngd_initrc_exec_t type, if you want to transition
182 an executable to the rngd_initrc_t domain.
183 rngd_unit_file_t
187 - Set files with the rngd_unit_file_t type, if you want to treat the
189 files as rngd unit content.
190 rngd_var_run_t
194 - Set files with the rngd_var_run_t type, if you want to store the rngd
196 files under the /run or /var/run directory.
197 Note: File context can be temporarily modified with the chcon command.
201 If you want to permanently change the file context you need to use the
202 semanage fcontext command. This will modify the SELinux labeling data‐
203 base. You will need to use restorecon to apply the labels.
204
207 semanage fcontext can also be used to manipulate default file context
208 mappings.
209 semanage permissive can also be used to manipulate whether or not a
211 process type is permissive.
212 semanage module can also be used to enable/disable/install/remove pol‐
214 icy modules.
215 semanage boolean can also be used to manipulate the booleans
217 system-config-selinux is a GUI tool available to customize SELinux pol‐
220 icy settings.
