NAME

6       clogd_selinux - Security Enhanced Linux Policy for the clogd processes
7

DESCRIPTION

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

ENTRYPOINTS

23       The clogd_t SELinux type can be entered via the clogd_exec_t file type.
24
25       The default entrypoint paths for the clogd_t domain are the following:
26
27       /usr/sbin/clogd
28

PROCESS TYPES

30       SELinux defines process types (domains) for each process running on the
31       system
32
33       You can see the context of a process using the -Z option to ps
34
35       Policy  governs  the  access confined processes have to files.  SELinux
36       clogd policy is very flexible allowing users to setup their clogd  pro‐
37       cesses in as secure a method as possible.
38
39       The following process types are defined for clogd:
40
41       clogd_t
42
43       Note:  semanage  permissive  -a clogd_t can be used to make the process
44       type clogd_t permissive. SELinux does not  deny  access  to  permissive
45       process  types, but the AVC (SELinux denials) messages are still gener‐
46       ated.
47
48

BOOLEANS

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

MANAGED FILES

138       The SELinux process type clogd_t can manage files labeled with the fol‐
139       lowing file types.  The paths listed are the default  paths  for  these
140       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

186       SELinux requires files to have an extended attribute to define the file
187       type.
188
189       You can see the context of a file using the -Z option to ls
190
191       Policy governs the access  confined  processes  have  to  these  files.
192       SELinux  clogd  policy  is  very flexible allowing users to setup their
193       clogd processes in as secure a method as possible.
194
195       STANDARD FILE CONTEXT
196
197       SELinux defines the file context types for the clogd, if you wanted  to
198       store  files  with  these types in a diffent paths, you need to execute
199       the semanage command  to  sepecify  alternate  labeling  and  then  use
200       restorecon to put the labels on disk.
201
202       semanage fcontext -a -t clogd_var_run_t '/srv/myclogd_content(/.*)?'
203       restorecon -R -v /srv/myclogd_content
204
205       Note:  SELinux  often  uses  regular expressions to specify labels that
206       match multiple files.
207
208       The following file types are defined for clogd:
209
210
211
212       clogd_exec_t
213
214       - Set files with the clogd_exec_t type, if you want  to  transition  an
215       executable to the clogd_t domain.
216
217
218
219       clogd_tmpfs_t
220
221       -  Set  files  with  the clogd_tmpfs_t type, if you want to store clogd
222       files on a tmpfs file system.
223
224
225
226       clogd_var_run_t
227
228       - Set files with the clogd_var_run_t type, if you  want  to  store  the
229       clogd files under the /run or /var/run directory.
230
231
232
233       Note:  File context can be temporarily modified with the chcon command.
234       If you want to permanently change the file context you need to use  the
235       semanage fcontext command.  This will modify the SELinux labeling data‐
236       base.  You will need to use restorecon to apply the labels.
237
238

COMMANDS

240       semanage fcontext can also be used to manipulate default  file  context
241       mappings.
242
243       semanage  permissive  can  also  be used to manipulate whether or not a
244       process type is permissive.
245
246       semanage module can also be used to enable/disable/install/remove  pol‐
247       icy modules.
248
249       semanage boolean can also be used to manipulate the booleans
250
251
252       system-config-selinux is a GUI tool available to customize SELinux pol‐
253       icy settings.
