NAME

6       rpcd_selinux - Security Enhanced Linux Policy for the rpcd processes
7

DESCRIPTION

9       Security-Enhanced  Linux secures the rpcd processes via flexible manda‐
10       tory access control.
11
12       The rpcd processes execute with the rpcd_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 rpcd_t
19
20
21

ENTRYPOINTS

23       The rpcd_t SELinux type can be entered via the rpcd_exec_t file type.
24
25       The default entrypoint paths for the rpcd_t domain are the following:
26
27       /sbin/rpc..*, /usr/sbin/rpc..*, /sbin/sm-notify,  /usr/sbin/rpc.idmapd,
28       /usr/sbin/rpc.rquotad
29

PROCESS TYPES

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

BOOLEANS

51       SELinux  policy  is  customizable based on least access required.  rpcd
52       policy is extremely flexible and has several booleans that allow you to
53       manipulate the policy and run rpcd with the tightest access possible.

MANAGED FILES

151       The SELinux process type rpcd_t can manage files labeled with the  fol‐
152       lowing  file  types.   The paths listed are the default paths for these
153       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

231       SELinux requires files to have an extended attribute to define the file
232       type.
233
234       You can see the context of a file using the -Z option to ls
235
236       Policy  governs  the  access  confined  processes  have to these files.
237       SELinux rpcd policy is very flexible allowing users to setup their rpcd
238       processes in as secure a method as possible.
239
240       EQUIVALENCE DIRECTORIES
241
242
243       rpcd  policy  stores  data  with  multiple different file context types
244       under the /var/run/rpc.statd directory.  If you would like to store the
245       data  in a different directory you can use the semanage command to cre‐
246       ate an equivalence mapping.  If you wanted to store this data under the
247       /srv dirctory you would execute the following command:
248
249       semanage fcontext -a -e /var/run/rpc.statd /srv/rpc.statd
250       restorecon -R -v /srv/rpc.statd
251
252       STANDARD FILE CONTEXT
253
254       SELinux  defines  the file context types for the rpcd, if you wanted to
255       store files with these types in a diffent paths, you  need  to  execute
256       the  semanage  command  to  sepecify  alternate  labeling  and then use
257       restorecon to put the labels on disk.
258
259       semanage fcontext -a -t rpcd_var_run_t '/srv/myrpcd_content(/.*)?'
260       restorecon -R -v /srv/myrpcd_content
261
262       Note: SELinux often uses regular expressions  to  specify  labels  that
263       match multiple files.
264
265       The following file types are defined for rpcd:
266
267
268
269       rpcd_exec_t
270
271       -  Set  files  with  the rpcd_exec_t type, if you want to transition an
272       executable to the rpcd_t domain.
273
274
275       Paths:
276            /sbin/rpc..*,          /usr/sbin/rpc..*,          /sbin/sm-notify,
277            /usr/sbin/rpc.idmapd, /usr/sbin/rpc.rquotad
278
279
280       rpcd_initrc_exec_t
281
282       - Set files with the rpcd_initrc_exec_t type, if you want to transition
283       an executable to the rpcd_initrc_t domain.
284
285
286       Paths:
287            /etc/rc.d/init.d/nfslock, /etc/rc.d/init.d/rpcidmapd
288
289
290       rpcd_var_run_t
291
292       - Set files with the rpcd_var_run_t type, if you want to store the rpcd
293       files under the /run or /var/run directory.
294
295
296       Paths:
297            /var/run/rpc.statd(/.*)?, /var/run/rpc.statd.pid
298
299
300       Note:  File context can be temporarily modified with the chcon command.
301       If you want to permanently change the file context you need to use  the
302       semanage fcontext command.  This will modify the SELinux labeling data‐
303       base.  You will need to use restorecon to apply the labels.
304
305

COMMANDS

307       semanage fcontext can also be used to manipulate default  file  context
308       mappings.
309
310       semanage  permissive  can  also  be used to manipulate whether or not a
311       process type is permissive.
312
313       semanage module can also be used to enable/disable/install/remove  pol‐
314       icy modules.
315
316       semanage boolean can also be used to manipulate the booleans
317
318
319       system-config-selinux is a GUI tool available to customize SELinux pol‐
320       icy settings.
