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/sm-notify,
28       /usr/sbin/rpc.idmapd, /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.
48
49

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

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

FILE CONTEXTS

251       SELinux requires files to have an extended attribute to define the file
252       type.
253
254       You can see the context of a file using the -Z option to ls
255
256       Policy  governs  the  access  confined  processes  have to these files.
257       SELinux rpcd policy is very flexible allowing users to setup their rpcd
258       processes in as secure a method as possible.
259
260       EQUIVALENCE DIRECTORIES
261
262
263       rpcd  policy  stores  data  with  multiple different file context types
264       under the /var/run/rpc.statd directory.  If you would like to store the
265       data  in a different directory you can use the semanage command to cre‐
266       ate an equivalence mapping.  If you wanted to store this data under the
267       /srv dirctory you would execute the following command:
268
269       semanage fcontext -a -e /var/run/rpc.statd /srv/rpc.statd
270       restorecon -R -v /srv/rpc.statd
271
272       STANDARD FILE CONTEXT
273
274       SELinux  defines  the file context types for the rpcd, if you wanted to
275       store files with these types in a diffent paths, you  need  to  execute
276       the  semanage  command  to  sepecify  alternate  labeling  and then use
277       restorecon to put the labels on disk.
278
279       semanage fcontext -a -t rpcd_var_run_t '/srv/myrpcd_content(/.*)?'
280       restorecon -R -v /srv/myrpcd_content
281
282       Note: SELinux often uses regular expressions  to  specify  labels  that
283       match multiple files.
284
285       The following file types are defined for rpcd:
286
287
288
289       rpcd_exec_t
290
291       -  Set  files  with  the rpcd_exec_t type, if you want to transition an
292       executable to the rpcd_t domain.
293
294
295       Paths:
296            /sbin/rpc..*,  /usr/sbin/rpc..*,  /sbin/sm-notify,   /usr/sbin/sm-
297            notify, /usr/sbin/rpc.idmapd, /usr/sbin/rpc.rquotad
298
299
300       rpcd_initrc_exec_t
301
302       - Set files with the rpcd_initrc_exec_t type, if you want to transition
303       an executable to the rpcd_initrc_t domain.
304
305
306       Paths:
307            /etc/rc.d/init.d/nfslock, /etc/rc.d/init.d/rpcidmapd
308
309
310       rpcd_unit_file_t
311
312       - Set files with the rpcd_unit_file_t type, if you want  to  treat  the
313       files as rpcd unit content.
314
315
316
317       rpcd_var_run_t
318
319       - Set files with the rpcd_var_run_t type, if you want to store the rpcd
320       files under the /run or /var/run directory.
321
322
323       Paths:
324            /var/run/sm-notify.*,                    /var/run/rpc.statd(/.*)?,
325            /var/run/rpc.statd.pid
326
327
328       Note:  File context can be temporarily modified with the chcon command.
329       If you want to permanently change the file context you need to use  the
330       semanage fcontext command.  This will modify the SELinux labeling data‐
331       base.  You will need to use restorecon to apply the labels.
332
333

COMMANDS

335       semanage fcontext can also be used to manipulate default  file  context
336       mappings.
337
338       semanage  permissive  can  also  be used to manipulate whether or not a
339       process type is permissive.
340
341       semanage module can also be used to enable/disable/install/remove  pol‐
342       icy modules.
343
344       semanage boolean can also be used to manipulate the booleans
345
346
347       system-config-selinux is a GUI tool available to customize SELinux pol‐
348       icy settings.
