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.
71
72
73
74       If you want to deny user domains applications to map a memory region as
75       both  executable  and  writable,  this  is dangerous and the executable
76       should be reported in bugzilla, you must turn on the deny_execmem bool‐
77       ean. Enabled by default.
78
79       setsebool -P deny_execmem 1
80
81
82
83       If you want to allow all domains to execute in fips_mode, you must turn
84       on the fips_mode boolean. Enabled by default.
85
86       setsebool -P fips_mode 1
87
88
89
90       If you want to control the ability to mmap a low area  of  the  address
91       space,  as  configured  by /proc/sys/vm/mmap_min_addr, you must turn on
92       the mmap_low_allowed boolean. Disabled by default.
93
94       setsebool -P mmap_low_allowed 1
95
96
97
98       If you want to allow confined applications to use nscd  shared  memory,
99       you must turn on the nscd_use_shm boolean. Disabled by default.
100
101       setsebool -P nscd_use_shm 1
102
103
104
105       If  you  want  to  disable  kernel module loading, you must turn on the
106       secure_mode_insmod boolean. Enabled by default.
107
108       setsebool -P secure_mode_insmod 1
109
110
111
112       If you want to allow unconfined executables to make their  heap  memory
113       executable.   Doing  this  is  a  really bad idea. Probably indicates a
114       badly coded executable, but could indicate an attack.  This  executable
115       should   be   reported  in  bugzilla,  you  must  turn  on  the  selin‐
116       uxuser_execheap boolean. Disabled by default.
117
118       setsebool -P selinuxuser_execheap 1
119
120
121
122       If you want to allow unconfined executables to make  their  stack  exe‐
123       cutable.   This  should  never, ever be necessary. Probably indicates a
124       badly coded executable, but could indicate an attack.  This  executable
125       should  be reported in bugzilla, you must turn on the selinuxuser_exec‐
126       stack boolean. Disabled by default.
127
128       setsebool -P selinuxuser_execstack 1

MANAGED FILES

133       The SELinux process type vmware_host_t can manage  files  labeled  with
134       the  following  file types.  The paths listed are the default paths for
135       these file types.  Note the processes UID still need to have  DAC  per‐
136       missions.
137
138       file_type
139
140            all files on the system
141
142

FILE CONTEXTS

144       SELinux requires files to have an extended attribute to define the file
145       type.
146
147       You can see the context of a file using the -Z option to ls
148
149       Policy governs the access  confined  processes  have  to  these  files.
150       SELinux  vmware_host  policy  is  very flexible allowing users to setup
151       their vmware_host processes in as secure a method as possible.
152
153       STANDARD FILE CONTEXT
154
155       SELinux defines the file context types  for  the  vmware_host,  if  you
156       wanted  to store files with these types in a diffent paths, you need to
157       execute the semanage command to sepecify alternate  labeling  and  then
158       use restorecon to put the labels on disk.
159
160       semanage  fcontext  -a  -t  vmware_host_tmp_t  '/srv/myvmware_host_con‐
161       tent(/.*)?'
162       restorecon -R -v /srv/myvmware_host_content
163
164       Note: SELinux often uses regular expressions  to  specify  labels  that
165       match multiple files.
166
167       The following file types are defined for vmware_host:
168
169
170
171       vmware_host_exec_t
172
173       - Set files with the vmware_host_exec_t type, if you want to transition
174       an executable to the vmware_host_t domain.
175
176
177       Paths:
178            /opt/vmware/(workstation|player)/bin/vmnet-natd,
179            /opt/vmware/(workstation|player)/bin/vmnet-dhcpd,
180            /opt/vmware/(workstation|player)/bin/vmware-nmbd,
181            /opt/vmware/(workstation|player)/bin/vmware-smbd,
182            /opt/vmware/(workstation|player)/bin/vmnet-bridge,
183            /opt/vmware/(workstation|player)/bin/vmnet-netifup,
184            /opt/vmware/(workstation|player)/bin/vmnet-sniffer,
185            /opt/vmware/(workstation|player)/bin/vmware-smbpasswd,
186            /opt/vmware/(workstation|player)/bin/vmware-smbpasswd.bin,
187            /usr/sbin/vmware-guest.*,   /usr/lib/vmware-tools/sbin32/vmware.*,
188            /usr/lib/vmware-tools/sbin64/vmware.*,        /usr/bin/vmnet-natd,
189            /usr/bin/vmware-vmx,  /usr/bin/vmnet-dhcpd,  /usr/bin/vmware-nmbd,
190            /usr/bin/vmware-smbd, /usr/bin/vmnet-bridge,  /usr/bin/vmnet-neti‐
191            fup,        /usr/bin/vmnet-sniffer,       /usr/bin/vmware-network,
192            /usr/bin/vmware-smbpasswd,          /usr/bin/vmware-smbpasswd.bin,
193            /usr/lib/vmware/bin/vmware-vmx
194
195
196       vmware_host_pid_t
197
198       -  Set  files with the vmware_host_pid_t type, if you want to store the
199       vmware host files under the /run directory.
200
201
202       Paths:
203            /var/run/vmnat.*, /var/run/vmnet.*, /var/run/vmware.*
204
205
206       vmware_host_tmp_t
207
208       - Set files with the vmware_host_tmp_t  type,  if  you  want  to  store
209       vmware host temporary files in the /tmp directories.
210
211
212
213       Note:  File context can be temporarily modified with the chcon command.
214       If you want to permanently change the file context you need to use  the
215       semanage fcontext command.  This will modify the SELinux labeling data‐
216       base.  You will need to use restorecon to apply the labels.
217
218

COMMANDS

220       semanage fcontext can also be used to manipulate default  file  context
221       mappings.
222
223       semanage  permissive  can  also  be used to manipulate whether or not a
224       process type is permissive.
225
226       semanage module can also be used to enable/disable/install/remove  pol‐
227       icy modules.
228
229       semanage boolean can also be used to manipulate the booleans
230
231
232       system-config-selinux is a GUI tool available to customize SELinux pol‐
233       icy settings.
