NAME

6       rpcbind_selinux  -  Security Enhanced Linux Policy for the rpcbind pro‐
7       cesses
8

DESCRIPTION

10       Security-Enhanced Linux secures  the  rpcbind  processes  via  flexible
11       mandatory access control.
12
13       The  rpcbind processes execute with the rpcbind_t SELinux type. You can
14       check if you have these processes running by executing the  ps  command
15       with the -Z qualifier.
16
17       For example:
18
19       ps -eZ | grep rpcbind_t
20
21
22

ENTRYPOINTS

24       The  rpcbind_t  SELinux type can be entered via the rpcbind_exec_t file
25       type.
26
27       The default entrypoint paths for the rpcbind_t domain are  the  follow‐
28       ing:
29
30       /sbin/rpcbind, /usr/sbin/rpcbind
31

PROCESS TYPES

33       SELinux defines process types (domains) for each process running on the
34       system
35
36       You can see the context of a process using the -Z option to ps
37
38       Policy governs the access confined processes have  to  files.   SELinux
39       rpcbind  policy  is very flexible allowing users to setup their rpcbind
40       processes in as secure a method as possible.
41
42       The following process types are defined for rpcbind:
43
44       rpcbind_t
45
46       Note: semanage permissive -a rpcbind_t can be used to make the  process
47       type  rpcbind_t  permissive. SELinux does not deny access to permissive
48       process types, but the AVC (SELinux denials) messages are still  gener‐
49       ated.
50
51

BOOLEANS

53       SELinux policy is customizable based on least access required.  rpcbind
54       policy is extremely flexible and has several booleans that allow you to
55       manipulate  the  policy and run rpcbind with the tightest access possi‐
56       ble.

MANAGED FILES

171       The SELinux process type rpcbind_t can manage files  labeled  with  the
172       following file types.  The paths listed are the default paths for these
173       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

225       SELinux requires files to have an extended attribute to define the file
226       type.
227
228       You can see the context of a file using the -Z option to ls
229
230       Policy  governs  the  access  confined  processes  have to these files.
231       SELinux rpcbind policy is very flexible allowing users to  setup  their
232       rpcbind processes in as secure a method as possible.
233
234       STANDARD FILE CONTEXT
235
236       SELinux  defines  the file context types for the rpcbind, if you wanted
237       to 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   rpcbind_var_run_t   '/srv/myrpcbind_con‐
242       tent(/.*)?'
243       restorecon -R -v /srv/myrpcbind_content
244
245       Note:  SELinux  often  uses  regular expressions to specify labels that
246       match multiple files.
247
248       The following file types are defined for rpcbind:
249
250
251
252       rpcbind_exec_t
253
254       - Set files with the rpcbind_exec_t type, if you want to transition  an
255       executable to the rpcbind_t domain.
256
257
258       Paths:
259            /sbin/rpcbind, /usr/sbin/rpcbind
260
261
262       rpcbind_initrc_exec_t
263
264       - Set files with the rpcbind_initrc_exec_t type, if you want to transi‐
265       tion an executable to the rpcbind_initrc_t domain.
266
267
268
269       rpcbind_tmp_t
270
271       - Set files with the rpcbind_tmp_t type, if you want to  store  rpcbind
272       temporary files in the /tmp directories.
273
274
275
276       rpcbind_var_lib_t
277
278       -  Set  files with the rpcbind_var_lib_t type, if you want to store the
279       rpcbind files under the /var/lib directory.
280
281
282       Paths:
283            /var/lib/rpcbind(/.*)?, /var/cache/rpcbind(/.*)?
284
285
286       rpcbind_var_run_t
287
288       - Set files with the rpcbind_var_run_t type, if you want to  store  the
289       rpcbind files under the /run or /var/run directory.
290
291
292       Paths:
293            /var/run/rpc.statd.pid, /var/run/rpcbind.*
294
295
296       Note:  File context can be temporarily modified with the chcon command.
297       If you want to permanently change the file context you need to use  the
298       semanage fcontext command.  This will modify the SELinux labeling data‐
299       base.  You will need to use restorecon to apply the labels.
300
301

COMMANDS

303       semanage fcontext can also be used to manipulate default  file  context
304       mappings.
305
306       semanage  permissive  can  also  be used to manipulate whether or not a
307       process type is permissive.
308
309       semanage module can also be used to enable/disable/install/remove  pol‐
310       icy modules.
311
312       semanage boolean can also be used to manipulate the booleans
313
314
315       system-config-selinux is a GUI tool available to customize SELinux pol‐
316       icy settings.
