NAME

6       radvd_selinux - Security Enhanced Linux Policy for the radvd processes
7

DESCRIPTION

9       Security-Enhanced Linux secures the radvd processes via flexible manda‐
10       tory access control.
11
12       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
16       For example:
17
18       ps -eZ | grep radvd_t
19
20
21

ENTRYPOINTS

23       The radvd_t SELinux type can be entered via the radvd_exec_t file type.
24
25       The default entrypoint paths for the radvd_t domain are the following:
26
27       /usr/sbin/radvd
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       radvd policy is very flexible allowing users to setup their radvd  pro‐
37       cesses in as secure a method as possible.
38
39       The following process types are defined for radvd:
40
41       radvd_t
42
43       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
48

BOOLEANS

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.

MANAGED FILES

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.

FILE CONTEXTS

213       SELinux requires files to have an extended attribute to define the file
214       type.
215
216       You can see the context of a file using the -Z option to ls
217
218       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
222       EQUIVALENCE DIRECTORIES
223
224
225       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
231       semanage fcontext -a -e /var/run/radvd /srv/radvd
232       restorecon -R -v /srv/radvd
233
234       STANDARD FILE CONTEXT
235
236       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
241       semanage fcontext -a -t radvd_var_run_t '/srv/myradvd_content(/.*)?'
242       restorecon -R -v /srv/myradvd_content
243
244       Note: SELinux often uses regular expressions  to  specify  labels  that
245       match multiple files.
246
247       The following file types are defined for radvd:
248
249
250
251       radvd_etc_t
252
253       - Set files with the radvd_etc_t type, if you want to store radvd files
254       in the /etc directories.
255
256
257
258       radvd_exec_t
259
260       - Set files with the radvd_exec_t type, if you want  to  transition  an
261       executable to the radvd_t domain.
262
263
264
265       radvd_initrc_exec_t
266
267       -  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
270
271
272       radvd_var_run_t
273
274       - 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
277
278       Paths:
279            /var/run/radvd(/.*)?, /var/run/radvd.pid
280
281
282       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
287

COMMANDS

289       semanage fcontext can also be used to manipulate default  file  context
290       mappings.
291
292       semanage  permissive  can  also  be used to manipulate whether or not a
293       process type is permissive.
294
295       semanage module can also be used to enable/disable/install/remove  pol‐
296       icy modules.
297
298       semanage boolean can also be used to manipulate the booleans
299
300
301       system-config-selinux is a GUI tool available to customize SELinux pol‐
302       icy settings.
