NAME

6       vhostmd_selinux  -  Security Enhanced Linux Policy for the vhostmd pro‐
7       cesses
8

DESCRIPTION

10       Security-Enhanced Linux secures  the  vhostmd  processes  via  flexible
11       mandatory access control.
12
13       The  vhostmd processes execute with the vhostmd_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 vhostmd_t
20
21
22

ENTRYPOINTS

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

171       The SELinux process type vhostmd_t can manage files  labeled  with  the
172       following file types.  The paths listed are the default paths for these
173       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

230       SELinux requires files to have an extended attribute to define the file
231       type.
232
233       You can see the context of a file using the -Z option to ls
234
235       Policy  governs  the  access  confined  processes  have to these files.
236       SELinux vhostmd policy is very flexible allowing users to  setup  their
237       vhostmd processes in as secure a method as possible.
238
239       STANDARD FILE CONTEXT
240
241       SELinux  defines  the file context types for the vhostmd, if you wanted
242       to store files with these types in a diffent paths, you need to execute
243       the  semanage  command  to  sepecify  alternate  labeling  and then use
244       restorecon to put the labels on disk.
245
246       semanage  fcontext   -a   -t   vhostmd_var_run_t   '/srv/myvhostmd_con‐
247       tent(/.*)?'
248       restorecon -R -v /srv/myvhostmd_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 vhostmd:
254
255
256
257       vhostmd_exec_t
258
259       - Set files with the vhostmd_exec_t type, if you want to transition  an
260       executable to the vhostmd_t domain.
261
262
263
264       vhostmd_initrc_exec_t
265
266       - Set files with the vhostmd_initrc_exec_t type, if you want to transi‐
267       tion an executable to the vhostmd_initrc_t domain.
268
269
270
271       vhostmd_tmpfs_t
272
273       - Set files with the vhostmd_tmpfs_t type, if you want to store vhostmd
274       files on a tmpfs file system.
275
276
277
278       vhostmd_var_run_t
279
280       -  Set  files with the vhostmd_var_run_t type, if you want to store the
281       vhostmd files under the /run or /var/run directory.
282
283
284
285       Note: File context can be temporarily modified with the chcon  command.
286       If  you want to permanently change the file context you need to use the
287       semanage fcontext command.  This will modify the SELinux labeling data‐
288       base.  You will need to use restorecon to apply the labels.
289
290

COMMANDS

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