NAME

6       kpropd_selinux  -  Security  Enhanced  Linux Policy for the kpropd pro‐
7       cesses
8

DESCRIPTION

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

ENTRYPOINTS

24       The  kpropd_t  SELinux  type  can be entered via the kpropd_exec_t file
25       type.
26
27       The default entrypoint paths for the kpropd_t domain are the following:
28
29       /usr/sbin/kpropd, /usr/sbin/_kpropd, /usr/kerberos/sbin/kpropd
30

PROCESS TYPES

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

BOOLEANS

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

PORT TYPES

169       SELinux defines port types to represent TCP and UDP ports.
170
171       You can see the types associated with a port  by  using  the  following
172       command:
173
174       semanage port -l
175
176
177       Policy  governs  the  access  confined  processes  have to these ports.
178       SELinux kpropd policy is very flexible allowing users  to  setup  their
179       kpropd processes in as secure a method as possible.
180
181       The following port types are defined for kpropd:
182
183
184       kprop_port_t
185
186
187
188       Default Defined Ports:
189                 tcp 754
190

MANAGED FILES

192       The  SELinux  process  type  kpropd_t can manage files labeled with the
193       following file types.  The paths listed are the default paths for these
194       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

264       SELinux requires files to have an extended attribute to define the file
265       type.
266
267       You can see the context of a file using the -Z option to ls
268
269       Policy governs the access  confined  processes  have  to  these  files.
270       SELinux  kpropd  policy  is very flexible allowing users to setup their
271       kpropd processes in as secure a method as possible.
272
273       The following file types are defined for kpropd:
274
275
276
277       kpropd_exec_t
278
279       - Set files with the kpropd_exec_t type, if you want to  transition  an
280       executable to the kpropd_t domain.
281
282
283       Paths:
284            /usr/sbin/kpropd, /usr/sbin/_kpropd, /usr/kerberos/sbin/kpropd
285
286
287       Note:  File context can be temporarily modified with the chcon command.
288       If you want to permanently change the file context you need to use  the
289       semanage fcontext command.  This will modify the SELinux labeling data‐
290       base.  You will need to use restorecon to apply the labels.
291
292

COMMANDS

294       semanage fcontext can also be used to manipulate default  file  context
295       mappings.
296
297       semanage  permissive  can  also  be used to manipulate whether or not a
298       process type is permissive.
299
300       semanage module can also be used to enable/disable/install/remove  pol‐
301       icy modules.
302
303       semanage port can also be used to manipulate the port definitions
304
305       semanage boolean can also be used to manipulate the booleans
306
307
308       system-config-selinux is a GUI tool available to customize SELinux pol‐
309       icy settings.
