NAME

6       vmware_host_selinux   -   Security   Enhanced   Linux  Policy  for  the
7       vmware_host processes
8

DESCRIPTION

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

ENTRYPOINTS

24       The    vmware_host_t    SELinux   type   can   be   entered   via   the
25       vmware_host_exec_t file type.
26
27       The default entrypoint paths for the vmware_host_t domain are the  fol‐
28       lowing:
29
30       /opt/vmware/(workstation|player)/bin/vmnet-natd,  /opt/vmware/(worksta‐
31       tion|player)/bin/vmnet-dhcpd,                     /opt/vmware/(worksta‐
32       tion|player)/bin/vmware-nmbd,                     /opt/vmware/(worksta‐
33       tion|player)/bin/vmware-smbd,                     /opt/vmware/(worksta‐
34       tion|player)/bin/vmnet-bridge,                    /opt/vmware/(worksta‐
35       tion|player)/bin/vmnet-netifup,                   /opt/vmware/(worksta‐
36       tion|player)/bin/vmnet-sniffer,                   /opt/vmware/(worksta‐
37       tion|player)/bin/vmware-smbpasswd,                /opt/vmware/(worksta‐
38       tion|player)/bin/vmware-smbpasswd.bin,        /usr/sbin/vmware-guest.*,
39       /usr/lib/vmware-tools/sbin32/vmware.*,                 /usr/lib/vmware-
40       tools/sbin64/vmware.*,     /usr/bin/vmnet-natd,    /usr/bin/vmware-vmx,
41       /usr/bin/vmnet-dhcpd,    /usr/bin/vmware-nmbd,    /usr/bin/vmware-smbd,
42       /usr/bin/vmnet-bridge,  /usr/bin/vmnet-netifup, /usr/bin/vmnet-sniffer,
43       /usr/bin/vmware-network,  /usr/bin/vmware-smbpasswd,   /usr/bin/vmware-
44       smbpasswd.bin, /usr/lib/vmware/bin/vmware-vmx

PROCESS TYPES

47       SELinux defines process types (domains) for each process running on the
48       system
49
50       You can see the context of a process using the -Z option to ps
51
52       Policy governs the access confined processes have  to  files.   SELinux
53       vmware_host  policy  is  very  flexible  allowing  users to setup their
54       vmware_host processes in as secure a method as possible.
55
56       The following process types are defined for vmware_host:
57
58       vmware_host_t
59
60       Note: semanage permissive -a vmware_host_t can  be  used  to  make  the
61       process  type vmware_host_t permissive. SELinux does not deny access to
62       permissive process types, but the AVC (SELinux  denials)  messages  are
63       still generated.
64
65

BOOLEANS

67       SELinux   policy  is  customizable  based  on  least  access  required.
68       vmware_host policy is extremely flexible and has several booleans  that
69       allow  you to manipulate the policy and run vmware_host with the tight‐
70       est access possible.

143       must  turn  on  the  domain_kernel_load_modules  boolean.  Disabled  by
144       default.
145
146       setsebool -P domain_kernel_load_modules 1
147
148

185
186       If you want to boolean to determine whether the system permits  loading
187       policy,  setting enforcing mode, and changing boolean values.  Set this

192
193
194
195       If  you  want to allow unconfined executables to make their heap memory
196       executable.  Doing this is a really  bad  idea.  Probably  indicates  a
197       badly  coded  executable, but could indicate an attack. This executable
198       should  be  reported  in  bugzilla,  you  must  turn  on   the   selin‐

214       cutable.  This should never, ever be necessary.  Probably  indicates  a
215       badly  coded  executable, but could indicate an attack. This executable
216       should be reported in bugzilla, you must turn on the  selinuxuser_exec‐
217       stack boolean. Enabled by default.
218
219       setsebool -P selinuxuser_execstack 1
220

222
223       If you want to support X userspace object manager, you must turn on the
224       xserver_object_manager boolean. Enabled by default.
225
226       setsebool -P xserver_object_manager 1

MANAGED FILES

231       The SELinux process type vmware_host_t can manage  files  labeled  with
232       the  following  file types.  The paths listed are the default paths for
233       these file types.  Note the processes UID still need to have  DAC  per‐
234       missions.
235
236       file_type
237
238            all files on the system
239
240

FILE CONTEXTS

242       SELinux requires files to have an extended attribute to define the file
243       type.
244
245       You can see the context of a file using the -Z option to ls
246
247       Policy governs the access  confined  processes  have  to  these  files.
248       SELinux  vmware_host  policy  is  very flexible allowing users to setup
249       their vmware_host processes in as secure a method as possible.
250
251       STANDARD FILE CONTEXT
252
253       SELinux defines the file context types  for  the  vmware_host,  if  you
254       wanted  to store files with these types in a diffent paths, you need to
255       execute the semanage command to sepecify alternate  labeling  and  then
256       use restorecon to put the labels on disk.
257
258       semanage  fcontext  -a  -t  vmware_host_tmp_t  '/srv/myvmware_host_con‐
259       tent(/.*)?'
260       restorecon -R -v /srv/myvmware_host_content
261
262       Note: SELinux often uses regular expressions  to  specify  labels  that
263       match multiple files.
264
265       The following file types are defined for vmware_host:
266
267
268
269       vmware_host_exec_t
270
271       - Set files with the vmware_host_exec_t type, if you want to transition
272       an executable to the vmware_host_t domain.
273
274
275       Paths:
276            /opt/vmware/(workstation|player)/bin/vmnet-natd,
277            /opt/vmware/(workstation|player)/bin/vmnet-dhcpd,
278            /opt/vmware/(workstation|player)/bin/vmware-nmbd,
279            /opt/vmware/(workstation|player)/bin/vmware-smbd,
280            /opt/vmware/(workstation|player)/bin/vmnet-bridge,
281            /opt/vmware/(workstation|player)/bin/vmnet-netifup,
282            /opt/vmware/(workstation|player)/bin/vmnet-sniffer,
283            /opt/vmware/(workstation|player)/bin/vmware-smbpasswd,
284            /opt/vmware/(workstation|player)/bin/vmware-smbpasswd.bin,
285            /usr/sbin/vmware-guest.*,   /usr/lib/vmware-tools/sbin32/vmware.*,
286            /usr/lib/vmware-tools/sbin64/vmware.*,        /usr/bin/vmnet-natd,
287            /usr/bin/vmware-vmx,  /usr/bin/vmnet-dhcpd,  /usr/bin/vmware-nmbd,
288            /usr/bin/vmware-smbd, /usr/bin/vmnet-bridge,  /usr/bin/vmnet-neti‐
289            fup,        /usr/bin/vmnet-sniffer,       /usr/bin/vmware-network,
290            /usr/bin/vmware-smbpasswd,          /usr/bin/vmware-smbpasswd.bin,
291            /usr/lib/vmware/bin/vmware-vmx
292
293
294       vmware_host_pid_t
295
296       -  Set  files with the vmware_host_pid_t type, if you want to store the
297       vmware host files under the /run directory.
298
299
300       Paths:
301            /var/run/vmnat.*, /var/run/vmnet.*, /var/run/vmware.*
302
303
304       vmware_host_tmp_t
305
306       - Set files with the vmware_host_tmp_t  type,  if  you  want  to  store
307       vmware host temporary files in the /tmp directories.
308
309
310
311       Note:  File context can be temporarily modified with the chcon command.
312       If you want to permanently change the file context you need to use  the
313       semanage fcontext command.  This will modify the SELinux labeling data‐
314       base.  You will need to use restorecon to apply the labels.
315
316

COMMANDS

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