NAME

6       hypervkvp_selinux  -  Security  Enhanced Linux Policy for the hypervkvp
7       processes
8

DESCRIPTION

10       Security-Enhanced Linux secures the hypervkvp  processes  via  flexible
11       mandatory access control.
12
13       The  hypervkvp processes execute with the hypervkvp_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 hypervkvp_t
20
21
22

ENTRYPOINTS

24       The  hypervkvp_t  SELinux  type can be entered via the hypervkvp_exec_t
25       file type.
26
27       The default entrypoint paths for the hypervkvp_t domain are the follow‐
28       ing:
29
30       /usr/sbin/hypervkvpd, /usr/sbin/hv_kvp_daemon
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       hypervkvp  policy is very flexible allowing users to setup their hyper‐
40       vkvp processes in as secure a method as possible.
41
42       The following process types are defined for hypervkvp:
43
44       hypervkvp_t
45
46       Note: semanage permissive -a  hypervkvp_t  can  be  used  to  make  the
47       process  type  hypervkvp_t  permissive. SELinux does not deny access to
48       permissive process types, but the AVC (SELinux  denials)  messages  are
49       still generated.
50
51

BOOLEANS

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

FILE CONTEXTS

247       SELinux requires files to have an extended attribute to define the file
248       type.
249
250       You can see the context of a file using the -Z option to ls
251
252       Policy  governs  the  access  confined  processes  have to these files.
253       SELinux hypervkvp policy is very flexible allowing users to setup their
254       hypervkvp processes in as secure a method as possible.
255
256       STANDARD FILE CONTEXT
257
258       SELinux defines the file context types for the hypervkvp, if you wanted
259       to store files with these types in a diffent paths, you need to execute
260       the  semanage  command  to  sepecify  alternate  labeling  and then use
261       restorecon to put the labels on disk.
262
263       semanage  fcontext  -a  -t  hypervkvp_var_lib_t  '/srv/myhypervkvp_con‐
264       tent(/.*)?'
265       restorecon -R -v /srv/myhypervkvp_content
266
267       Note:  SELinux  often  uses  regular expressions to specify labels that
268       match multiple files.
269
270       The following file types are defined for hypervkvp:
271
272
273
274       hypervkvp_exec_t
275
276       - Set files with the hypervkvp_exec_t type, if you want  to  transition
277       an executable to the hypervkvp_t domain.
278
279
280       Paths:
281            /usr/sbin/hypervkvpd, /usr/sbin/hv_kvp_daemon
282
283
284       hypervkvp_initrc_exec_t
285
286       - Set files with the hypervkvp_initrc_exec_t type, if you want to tran‐
287       sition an executable to the hypervkvp_initrc_t domain.
288
289
290
291       hypervkvp_tmp_t
292
293       - Set files with the hypervkvp_tmp_t type, if you want to store  hyper‐
294       vkvp temporary files in the /tmp directories.
295
296
297
298       hypervkvp_unit_file_t
299
300       -  Set  files with the hypervkvp_unit_file_t type, if you want to treat
301       the files as hypervkvp unit content.
302
303
304
305       hypervkvp_var_lib_t
306
307       - Set files with the hypervkvp_var_lib_t type, if you want to store the
308       hypervkvp files under the /var/lib directory.
309
310
311
312       Note:  File context can be temporarily modified with the chcon command.
313       If you want to permanently change the file context you need to use  the
314       semanage fcontext command.  This will modify the SELinux labeling data‐
315       base.  You will need to use restorecon to apply the labels.
316
317

COMMANDS

319       semanage fcontext can also be used to manipulate default  file  context
320       mappings.
321
322       semanage  permissive  can  also  be used to manipulate whether or not a
323       process type is permissive.
324
325       semanage module can also be used to enable/disable/install/remove  pol‐
326       icy modules.
327
328       semanage boolean can also be used to manipulate the booleans
329
330
331       system-config-selinux is a GUI tool available to customize SELinux pol‐
332       icy settings.
