NAME

6       snapperd_selinux - Security Enhanced Linux Policy for the snapperd pro‐
7       cesses
8

DESCRIPTION

10       Security-Enhanced Linux secures the  snapperd  processes  via  flexible
11       mandatory access control.
12
13       The  snapperd  processes  execute with the snapperd_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 snapperd_t
20
21
22

ENTRYPOINTS

24       The snapperd_t SELinux type can be entered via the snapperd_exec_t file
25       type.
26
27       The default entrypoint paths for the snapperd_t domain are the  follow‐
28       ing:
29
30       /usr/sbin/snapperd
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       snapperd policy is very flexible allowing users to setup their snapperd
40       processes in as secure a method as possible.
41
42       The following process types are defined for snapperd:
43
44       snapperd_t
45
46       Note: semanage permissive -a snapperd_t can be used to make the process
47       type  snapperd_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.  snap‐
54       perd policy is extremely flexible and has several booleans  that  allow
55       you  to manipulate the policy and run snapperd with the tightest access
56       possible.

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 snapperd policy is very flexible allowing users to setup  their
238       snapperd processes in as secure a method as possible.
239
240       STANDARD FILE CONTEXT
241
242       SELinux  defines the file context types for the snapperd, if you wanted
243       to store files with these types in a diffent paths, you need to execute
244       the  semanage  command  to  sepecify  alternate  labeling  and then use
245       restorecon to put the labels on disk.
246
247       semanage fcontext -a -t snapperd_log_t '/srv/mysnapperd_content(/.*)?'
248       restorecon -R -v /srv/mysnapperd_content
249
250       Note: SELinux often uses regular expressions  to  specify  labels  that
251       match multiple files.
252
253       The following file types are defined for snapperd:
254
255
256
257       snapperd_conf_t
258
259       -  Set  files  with  the snapperd_conf_t type, if you want to treat the
260       files as snapperd configuration data, usually  stored  under  the  /etc
261       directory.
262
263
264       Paths:
265            /etc/snapper(/.*)?, /etc/sysconfig/snapper
266
267
268       snapperd_data_t
269
270       -  Set  files  with  the snapperd_data_t type, if you want to treat the
271       files as snapperd content.
272
273
274       Paths:
275            /mnt/(.*/)?.snapshots(/.*)?, /home/(.*/)?.snapshots(/.*)?, /.snap‐
276            shots(/.*)?,     /usr/.snapshots(/.*)?,     /var/.snapshots(/.*)?,
277            /etc/.snapshots(/.*)?, /home/.snapshots(/.*)?
278
279
280       snapperd_exec_t
281
282       - Set files with the snapperd_exec_t type, if you want to transition an
283       executable to the snapperd_t domain.
284
285
286
287       snapperd_log_t
288
289       - Set files with the snapperd_log_t type, if you want to treat the data
290       as snapperd log data, usually stored under the /var/log directory.
291
292
293
294       Note: File context can be temporarily modified with the chcon  command.
295       If  you want to permanently change the file context you need to use the
296       semanage fcontext command.  This will modify the SELinux labeling data‐
297       base.  You will need to use restorecon to apply the labels.
298
299

COMMANDS

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