6 radvd_selinux - Security Enhanced Linux Policy for the radvd processes
7
9 Security-Enhanced Linux secures the radvd processes via flexible manda‐
10 tory access control.
11 The radvd processes execute with the radvd_t SELinux type. You can
13 check if you have these processes running by executing the ps command
14 with the -Z qualifier.
15 For example:
17 ps -eZ | grep radvd_t
19
23 The radvd_t SELinux type can be entered via the radvd_exec_t file type.
24 The default entrypoint paths for the radvd_t domain are the following:
26 /usr/sbin/radvd
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 radvd policy is very flexible allowing users to setup their radvd pro‐
37 cesses in as secure a method as possible.
38 The following process types are defined for radvd:
40 radvd_t
42 Note: semanage permissive -a radvd_t can be used to make the process
44 type radvd_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. radvd
51 policy is extremely flexible and has several booleans that allow you to
52 manipulate the policy and run radvd with the tightest access possible.
53 If you want to allow users to resolve user passwd entries directly from
57 ldap rather then using a sssd server, you must turn on the authlo‐
58 gin_nsswitch_use_ldap boolean. Disabled by default.

139 on the global_ssp boolean. Disabled by default.
140 setsebool -P global_ssp 1
142 If you want to allow confined applications to run with kerberos, you
146 must turn on the kerberos_enabled boolean. Enabled by default.
147 setsebool -P kerberos_enabled 1
149 If you want to allow system to run with NIS, you must turn on the
153 nis_enabled boolean. Disabled by default.
154 setsebool -P nis_enabled 1
156 If you want to allow confined applications to use nscd shared memory,
160 you must turn on the nscd_use_shm boolean. Disabled by default.
161 setsebool -P nscd_use_shm 1

167 The SELinux process type radvd_t can manage files labeled with the fol‐
168 lowing file types. The paths listed are the default paths for these
169 file types. Note the processes UID still need to have DAC permissions.

213 SELinux requires files to have an extended attribute to define the file
214 type.
215 You can see the context of a file using the -Z option to ls
217 Policy governs the access confined processes have to these files.
219 SELinux radvd policy is very flexible allowing users to setup their
220 radvd processes in as secure a method as possible.
221 EQUIVALENCE DIRECTORIES
223 radvd policy stores data with multiple different file context types
226 under the /var/run/radvd directory. If you would like to store the
227 data in a different directory you can use the semanage command to cre‐
228 ate an equivalence mapping. If you wanted to store this data under the
229 /srv dirctory you would execute the following command:
230 semanage fcontext -a -e /var/run/radvd /srv/radvd
232 restorecon -R -v /srv/radvd
233 STANDARD FILE CONTEXT
235 SELinux defines the file context types for the radvd, if you wanted to
237 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 semanage fcontext -a -t radvd_var_run_t '/srv/myradvd_content(/.*)?'
242 restorecon -R -v /srv/myradvd_content
243 Note: SELinux often uses regular expressions to specify labels that
245 match multiple files.
246 The following file types are defined for radvd:
248 radvd_etc_t
252 - Set files with the radvd_etc_t type, if you want to store radvd files
254 in the /etc directories.
255 radvd_exec_t
259 - Set files with the radvd_exec_t type, if you want to transition an
261 executable to the radvd_t domain.
262 radvd_initrc_exec_t
266 - Set files with the radvd_initrc_exec_t type, if you want to transi‐
268 tion an executable to the radvd_initrc_t domain.
269 radvd_var_run_t
273 - Set files with the radvd_var_run_t type, if you want to store the
275 radvd files under the /run or /var/run directory.
276 Paths:
279 /var/run/radvd(/.*)?, /var/run/radvd.pid
280 Note: File context can be temporarily modified with the chcon command.
283 If you want to permanently change the file context you need to use the
284 semanage fcontext command. This will modify the SELinux labeling data‐
285 base. You will need to use restorecon to apply the labels.
286
289 semanage fcontext can also be used to manipulate default file context
290 mappings.
291 semanage permissive can also be used to manipulate whether or not a
293 process type is permissive.
294 semanage module can also be used to enable/disable/install/remove pol‐
296 icy modules.
297 semanage boolean can also be used to manipulate the booleans
299 system-config-selinux is a GUI tool available to customize SELinux pol‐
302 icy settings.
