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

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
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 control the ability to mmap a low area of the address
75 space, as configured by /proc/sys/vm/mmap_min_addr, you must turn on
76 the mmap_low_allowed boolean. Disabled by default.
77
78 setsebool -P mmap_low_allowed 1
79
80
81
82 If you want to allow unconfined executables to make their heap memory
83 executable. Doing this is a really bad idea. Probably indicates a
84 badly coded executable, but could indicate an attack. This executable
85 should be reported in bugzilla, you must turn on the selin‐
86 uxuser_execheap boolean. Disabled by default.
87
88 setsebool -P selinuxuser_execheap 1
89

91
93 The SELinux process type vmware_host_t can manage files labeled with
94 the following file types. The paths listed are the default paths for
95 these file types. Note the processes UID still need to have DAC per‐
96 missions.
97
98 file_type
99
100 all files on the system
101
102
104 SELinux requires files to have an extended attribute to define the file
105 type.
106
107 You can see the context of a file using the -Z option to ls
108
109 Policy governs the access confined processes have to these files.
110 SELinux vmware_host policy is very flexible allowing users to setup
111 their vmware_host processes in as secure a method as possible.
112
113 STANDARD FILE CONTEXT
114
115 SELinux defines the file context types for the vmware_host, if you
116 wanted to store files with these types in a diffent paths, you need to
117 execute the semanage command to sepecify alternate labeling and then
118 use restorecon to put the labels on disk.
119
120 semanage fcontext -a -t vmware_host_tmp_t '/srv/myvmware_host_con‐
121 tent(/.*)?'
122 restorecon -R -v /srv/myvmware_host_content
123
124 Note: SELinux often uses regular expressions to specify labels that
125 match multiple files.
126
127 The following file types are defined for vmware_host:
128
129
130
131 vmware_host_exec_t
132
133 - Set files with the vmware_host_exec_t type, if you want to transition
134 an executable to the vmware_host_t domain.
135
136
137 Paths:
138 /opt/vmware/(workstation|player)/bin/vmnet-natd,
139 /opt/vmware/(workstation|player)/bin/vmnet-dhcpd,
140 /opt/vmware/(workstation|player)/bin/vmware-nmbd,
141 /opt/vmware/(workstation|player)/bin/vmware-smbd,
142 /opt/vmware/(workstation|player)/bin/vmnet-bridge,
143 /opt/vmware/(workstation|player)/bin/vmnet-netifup,
144 /opt/vmware/(workstation|player)/bin/vmnet-sniffer,
145 /opt/vmware/(workstation|player)/bin/vmware-smbpasswd,
146 /opt/vmware/(workstation|player)/bin/vmware-smbpasswd.bin,
147 /usr/sbin/vmware-guest.*, /usr/lib/vmware-tools/sbin32/vmware.*,
148 /usr/lib/vmware-tools/sbin64/vmware.*, /usr/bin/vmnet-natd,
149 /usr/bin/vmware-vmx, /usr/bin/vmnet-dhcpd, /usr/bin/vmware-nmbd,
150 /usr/bin/vmware-smbd, /usr/bin/vmnet-bridge, /usr/bin/vmnet-neti‐
151 fup, /usr/bin/vmnet-sniffer, /usr/bin/vmware-network,
152 /usr/bin/vmware-smbpasswd, /usr/bin/vmware-smbpasswd.bin,
153 /usr/lib/vmware/bin/vmware-vmx
154
155
156 vmware_host_pid_t
157
158 - Set files with the vmware_host_pid_t type, if you want to store the
159 vmware host files under the /run directory.
160
161
162 Paths:
163 /var/run/vmnat.*, /var/run/vmnet.*, /var/run/vmware.*
164
165
166 vmware_host_tmp_t
167
168 - Set files with the vmware_host_tmp_t type, if you want to store
169 vmware host temporary files in the /tmp directories.
170
171
172
173 Note: File context can be temporarily modified with the chcon command.
174 If you want to permanently change the file context you need to use the
175 semanage fcontext command. This will modify the SELinux labeling data‐
176 base. You will need to use restorecon to apply the labels.
177
178
180 semanage fcontext can also be used to manipulate default file context
181 mappings.
182
183 semanage permissive can also be used to manipulate whether or not a
184 process type is permissive.
185
186 semanage module can also be used to enable/disable/install/remove pol‐
187 icy modules.
188
189 semanage boolean can also be used to manipulate the booleans
190
191
192 system-config-selinux is a GUI tool available to customize SELinux pol‐
193 icy settings.
