NAME

6       klogd_selinux - Security Enhanced Linux Policy for the klogd processes
7

DESCRIPTION

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

ENTRYPOINTS

23       The klogd_t SELinux type can be entered via the klogd_exec_t file type.
24
25       The default entrypoint paths for the klogd_t domain are the following:
26
27       /sbin/klogd, /sbin/rklogd, /usr/sbin/klogd, /usr/sbin/rklogd
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       klogd policy is very flexible allowing users to setup their klogd  pro‐
37       cesses in as secure a method as possible.
38
39       The following process types are defined for klogd:
40
41       klogd_t
42
43       Note:  semanage  permissive  -a klogd_t can be used to make the process
44       type klogd_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.   klogd
51       policy is extremely flexible and has several booleans that allow you to
52       manipulate the policy and run klogd with the tightest access possible.

MANAGED FILES

129       The SELinux process type klogd_t can manage files labeled with the fol‐
130       lowing  file  types.   The paths listed are the default paths for these
131       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

199       SELinux requires files to have an extended attribute to define the file
200       type.
201
202       You can see the context of a file using the -Z option to ls
203
204       Policy  governs  the  access  confined  processes  have to these files.
205       SELinux klogd policy is very flexible allowing  users  to  setup  their
206       klogd processes in as secure a method as possible.
207
208       STANDARD FILE CONTEXT
209
210       SELinux  defines the file context types for the klogd, if you wanted to
211       store files with these types in a diffent paths, you  need  to  execute
212       the  semanage  command  to  sepecify  alternate  labeling  and then use
213       restorecon to put the labels on disk.
214
215       semanage fcontext -a -t klogd_var_run_t '/srv/myklogd_content(/.*)?'
216       restorecon -R -v /srv/myklogd_content
217
218       Note: SELinux often uses regular expressions  to  specify  labels  that
219       match multiple files.
220
221       The following file types are defined for klogd:
222
223
224
225       klogd_exec_t
226
227       -  Set  files  with the klogd_exec_t type, if you want to transition an
228       executable to the klogd_t domain.
229
230
231       Paths:
232            /sbin/klogd, /sbin/rklogd, /usr/sbin/klogd, /usr/sbin/rklogd
233
234
235       klogd_tmp_t
236
237       - Set files with the klogd_tmp_t type, if you want to store klogd  tem‐
238       porary files in the /tmp directories.
239
240
241
242       klogd_var_run_t
243
244       -  Set  files  with  the klogd_var_run_t type, if you want to store the
245       klogd files under the /run or /var/run directory.
246
247
248
249       Note: File context can be temporarily modified with the chcon  command.
250       If  you want to permanently change the file context you need to use the
251       semanage fcontext command.  This will modify the SELinux labeling data‐
252       base.  You will need to use restorecon to apply the labels.
253
254

COMMANDS

256       semanage  fcontext  can also be used to manipulate default file context
257       mappings.
258
259       semanage permissive can also be used to manipulate  whether  or  not  a
260       process type is permissive.
261
262       semanage  module can also be used to enable/disable/install/remove pol‐
263       icy modules.
264
265       semanage boolean can also be used to manipulate the booleans
266
267
268       system-config-selinux is a GUI tool available to customize SELinux pol‐
269       icy settings.
