NAME

6       tmpreaper_selinux  -  Security  Enhanced Linux Policy for the tmpreaper
7       processes
8

DESCRIPTION

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

ENTRYPOINTS

24       The  tmpreaper_t  SELinux  type can be entered via the tmpreaper_exec_t
25       file type.
26
27       The default entrypoint paths for the tmpreaper_t domain are the follow‐
28       ing:
29
30       /usr/sbin/tmpwatch,   /usr/sbin/tmpreaper,   /etc/rc.d/init.d/mountall-
31       bootclean.sh, /etc/rc.d/init.d/mountnfs-bootclean.sh
32

PROCESS TYPES

34       SELinux defines process types (domains) for each process running on the
35       system
36
37       You can see the context of a process using the -Z option to ps
38
39       Policy  governs  the  access confined processes have to files.  SELinux
40       tmpreaper policy  is  very  flexible  allowing  users  to  setup  their
41       tmpreaper processes in as secure a method as possible.
42
43       The following process types are defined for tmpreaper:
44
45       tmpreaper_t
46
47       Note:  semanage  permissive  -a  tmpreaper_t  can  be  used to make the
48       process type tmpreaper_t permissive. SELinux does not  deny  access  to
49       permissive  process  types,  but the AVC (SELinux denials) messages are
50       still generated.
51
52

BOOLEANS

54       SELinux  policy  is  customizable  based  on  least  access   required.
55       tmpreaper  policy  is  extremely flexible and has several booleans that
56       allow you to manipulate the policy and run tmpreaper with the  tightest
57       access possible.

MANAGED FILES

172       The  SELinux process type tmpreaper_t can manage files labeled with the
173       following file types.  The paths listed are the default paths for these
174       file types.  Note the processes UID still need to have DAC permissions.
175
176       antivirus_db_t
177

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 tmpreaper policy is very flexible allowing users to setup their
220       tmpreaper processes in as secure a method as possible.
221
222       The following file types are defined for tmpreaper:
223
224
225
226       tmpreaper_exec_t
227
228       - Set files with the tmpreaper_exec_t type, if you want  to  transition
229       an executable to the tmpreaper_t domain.
230
231
232       Paths:
233            /usr/sbin/tmpwatch,   /usr/sbin/tmpreaper,  /etc/rc.d/init.d/moun‐
234            tall-bootclean.sh, /etc/rc.d/init.d/mountnfs-bootclean.sh
235
236
237       Note: File context can be temporarily modified with the chcon  command.
238       If  you want to permanently change the file context you need to use the
239       semanage fcontext command.  This will modify the SELinux labeling data‐
240       base.  You will need to use restorecon to apply the labels.
241
242

COMMANDS

244       semanage  fcontext  can also be used to manipulate default file context
245       mappings.
246
247       semanage permissive can also be used to manipulate  whether  or  not  a
248       process type is permissive.
249
250       semanage  module can also be used to enable/disable/install/remove pol‐
251       icy modules.
252
253       semanage boolean can also be used to manipulate the booleans
254
255
256       system-config-selinux is a GUI tool available to customize SELinux pol‐
257       icy settings.
